How to choose high-quality crimping machine

How to choose high-quality crimping machine

How to choose high-quality crimping machine The products on the market are good and bad, and so are the crimping machines, so how do we buy high-quality crimping machines when we buy crimping machines? Here are three tips for everyone, I hope it will be helpful to everyone . Look: Observe visually whether the hydraulic accessories and electrical components selected by the crimping machine are brand-name products or are produced by regular manufacturers; whether the circuit configuration is regular; whether the design of the oil station pipeline is reasonable; whether there is oil leakage at the connection. If the above passes the visual inspection, you can proceed to the next step. Listen: Turn on the device after connecting it to the power source, and listen to whether the device is running normally. If there is abnormal noise, it is often caused by the installation coaxiality of the motor and the oil pump. Another possibility is caused by the unreasonable selection of the oil pump displacement and pipe diameter, and the quality of the selected motor or oil pump. Not very well caused. Measurement: After **, the main parameters of the equipment are measured Keep the equipment in a dry running state, touch each module block with your hand, and there should be no jitter in the hand, otherwise it will be regarded as a substandard product. Install the equipment on the mold, crimp a sample joint, measure the crimp joint with a caliper or a micrometer, the roundness and taper should be buckled within 0.1mm, which is considered excellent. Mold base hardness and mold hardness are also the key to the normal use of the equipment in the future. Customers can request manufacturers to use a desktop or portable hardness tester to test the mold base or mold. When the hardness of the mold base is lower than Rockwell HRC60 and the mold hardness is lower than Rockwell HRC50, it will affect the withholding quality of the hose. **After the inspection, the eight petals of the mold base of the equipment and the flatness of the mold are inspected. Good equipment will specifically control and adjust these two parameters, while some low-quality equipment does not control the above two parameters. The crimping machine is a combination of various engineering machinery, forming a device that integrates multiple purposes, and realizes one machine with multiple functions.

New technology of stripping machine

New technology of stripping machine

New technology of stripping machine The new technical task is to address the shortcomings of the existing technology and provide a hose stripping machine. During the stripping process, the hose is clamped by the clamping device, eliminating the need for manual hand gripping of the hose for stripping, reducing the working strength while ensuring Safety. The technical scheme adopted by the utility model to solve its technical problems is: A rubber hose stripping machine includes a frame, a rubber stripping device and a power traction device horizontally fixed on the frame. The power traction device is extended with a mandrel, and the mandrel is fixedly connected with the rubber stripping device. A hose clamping mechanism is horizontally arranged on the frame, and the hose clamping mechanism includes a clamping seat, a clamping power device and a clamping block. The clamping seat is arranged perpendicular to the axial direction of the mandrel and horizontally fixed on the end of the frame away from the power traction device; the clamping seat is provided with a left-right symmetrical support frame. The clamping power device is horizontally fixed on the support frame and connected with clamping blocks arranged symmetrically. The clamping blocks arranged symmetrically form a rubber tube clamping cavity in the working state, and the rubber tube clamping cavity is concentric with the mandrel to ensure the clamping position of the rubber tube. The clamping power device is connected with a foot valve, and the operator controls the clamping and loosening of the tightening mechanism through the foot valve. Preferably, the power traction device includes a motor and a speed changer. The output shaft of the motor is connected to the input shaft of the speed changer, and the output shaft of the speed changer is fixedly connected to the mandrel. The speed is changed by the speed changer to adapt to different types of hoses. Preferably, the glue stripping device includes a connecting rod, a knife holder and a glue stripping knife. The connecting rod is perpendicular to the mandrel and fixed on the mandrel, one end of the connecting rod is horizontally fixed with a knife holder through an adjusting screw, and a rubber stripping knife is arranged on the knife holder. Adapt to different diameter hoses by adjusting the position of the knife holder. Preferably, the connecting rod is a rectangular block, the center is fixed with the mandrel, the two ends are respectively provided with waist-shaped holes symmetrically, and the tool holder is fixed at the waist-shaped holes by adjusting screws. Preferably, the clamping power device includes two clamping oil cylinders arranged symmetrically, and the two clamping oil cylinders are connected in parallel, and the parallel connection of the liquid inlet pipe and the liquid outlet pipe is connected with an oil pump through a foot valve. The parallel connection of two symmetrical clamping oil cylinders can ensure that the position of the shaft center is unchanged when the hoses of different diameters are clamped, thereby ensuring the processing quality. Preferably, the clamping power device includes two cylinders arranged symmetrically on the left and right sides, the two cylinders are connected in parallel, and the parallel inlet pipe and the outlet pipe are connected to the compressor through a foot valve. Further, a dust collecting groove is provided at the lower part of the frame, and the dust collecting groove is correspondingly arranged under the glue stripping device. Further, a non-slip surface is provided on the clamping block. Further, a protective cover is arranged above the glue stripping device, and flying debris hurts people during the placement work. Compared with the prior art, the rubber hose stripping machine of the utility model has the beneficial effect that in the rubber stripping process, the operator controls the rubber hose clamping device to clamp the rubber hose through the foot valve, instead of the original manual Holding the rubber tube rotated by the peeling force reduces the work intensity of the operator, especially improves the work efficiency when dealing with mass peeling tasks. This structure also ensures the safety of the operator.

Technical background and use of hose crimping machine

Technical background and use of hose crimping machine

Technical background and use of hose crimping machine At present, the hose crimping machine produced by domestic manufacturers still adopts the drawings designed in the 1950s, and is made by the principle of four-column horizontal one-way extrusion. The imported hose crimping machine has exquisite materials and flexible operation, but the structure is similar to the domestic one. This type of hose crimping machine is mainly composed of a fuselage under the workbench, a hydraulic cylinder on the workbench and a horizontal four-post bracket. The fuselage mainly includes fuel tanks, valves and connecting pipes. The front and rear ends of the horizontal four-post bracket are fixed There are two sliding plates sleeved on the four pillars in the middle, which can slide in the direction of the pillars. There are connecting screws between the two sliding plates. A hydraulic cylinder is connected to the fixed plate at the rear end of the four-pillar bracket. A piston and a piston rod are provided. The piston divides the hydraulic cylinder into two oil chambers. The cylinder walls of the two oil chambers are respectively provided with inlet and outlet oil passages. The inlet and outlet oil passages are connected to the oil tank in the fuselage through connecting pipes. The front end of the rod is connected to the sliding plate at the front end of the rear fixed plate. The sliding plate at the front end of the sliding plate has a hollow structure. The front end of the sliding plate of the hollow structure is connected with a shrink sleeve. The fixed plate at the front end of the four-post bracket is a hollow structure. The fixed plate at the front end of the four-post bracket is evenly distributed with radial T-shaped guide rails. The T-shaped guide rail is equipped with a sliding block with an outer slope and an inner slope of the shrink sleeve. The sliding block can slide on the T-shaped guide rail to lock the pipeline to be locked. . When this pipe locking machine is in use, the threaded lock leather is sleeved on the end surface of the pipe to be locked, and the end surface is extended from the hollow of the fixed plate at the front end of the four-post bracket. The piston moves forward by the push of oil pressure. The rod drives the sliding plate to slide forward, and the sliding plate drives the sliding plate of the hollow structure to slide in the same direction. The shrink sleeve on the sliding plate of the hollow structure pushes the squeeze slider to radially slide the pipe to be locked on the T-shaped guide rail. Lock, and then take out this pipe fitting. Similarly, put the lock holster with nut on the end of another pipe to lock the other pipe, and then screw the two pipes together, so that during use A loose head accident may occur in Therefore, this pipe locking machine can only perform one-way end-face locking, which is very inconvenient for pipe docking. In addition, because the length of the horizontal four-post bracket of the pipe locking machine is fixed, it cannot lock some large end-face parts with long ends. Close, and the body is heavy and inconvenient to move. In order to solve the shortcomings that the existing hose crimping machine can only crimp one-way end face and cannot crimp large end-face parts, a hydraulic hose crimping machine is provided, which changes the original one-way crimp only into Pass lock. The technical scheme adopted by the present invention to solve its technical problems is: it includes a fuselage composed of an oil tank, a motor oil pump unit, a program-controlled valve block and a connecting pipe, and a locking assembly fixedly assembled on the fuselage. The cylinder liner is the main body. A hollow piston is arranged in the cylinder liner. A sealing sleeve matching the front end of the piston is provided on the inner wall of the front end of the cylinder liner. The sealing sleeve forms an annular sealing return oil cavity between the inner wall of the piston and the cylinder liner. , The cylinder liner wall is provided with a return oil passage communicating with the return oil cavity, the inner cavity of the piston is a bell mouth shape, the piston and the hollow structure piston rod are of unequal diameter structure, and the rear end of the cylinder liner is assembled In the end cover, the piston rod is in close contact with the inner surface of the back end cover. The back end cover and the inner walls of the piston, piston rod and cylinder liner form an annular sealed process oil chamber. The back end cover is provided with a process communicating with the process oil chamber. The oil passage, return oil passage and process oil passage are connected to the oil tank in the fuselage through connecting pipes. The front end of the cylinder liner is equipped with a hollow locking bracket. The locking bracket is evenly distributed with radial guide rails. A sliding block with an outer inclined surface that can slide radially along the guide rail and an inner inclined s
