Instructions and principles of the hose crimping machine

Instructions and principles of the hose crimping machine The hose crimping machine is a special equipment such as (hydraulic machinery, excavators, loaders, cranes, automobile air-conditioning hoses) that deform the metal joints under pressure, so as to smoothly and accurately crimp the hoses. It is a hydraulic machinery factory , Required equipment for excavator repair points. This tube press module adopts double inclined surface design, with increased buckle pressure, no taper of the tube, long service life, low noise, small size, light weight, multiple functions, fast mold opening, easy operation, and easy maintenance. The plunger pump is installed in the oil tank and soaked in the hydraulic oil to achieve the purpose of scientific heat dissipation and mute design. The plunger pump is driven by the motor to output hydraulic oil and push the plunger in the withholding cylinder to move, causing the mold base to shrink radially to realize the mold. Squeeze the outer sleeve of the hose joint. When the shrinkage reaches the preset value of the micrometer, the squeezing stops automatically. After the electromagnetic reversing valve changes direction, the plunger in the cylinder moves in the opposite direction, the mold opens, and the hose is crimped. Test Example of hose crimping machine Refer to the plastic hose to be crimped for the selected mold. If you are not satisfied after crimping, fine-tune the micrometer and crimp a hose. When crimping the hose joint: Too much crimping size, the rubber layer in the hose is crushed, causing oil leakage; too small crimping size, causing oil leakage and being flushed out of the joint by hydraulic pressure. Be sure to grasp a reasonable degree of crimping, subject to the shrinkage of the inner hole of the connector core. Precautions for hose crimping machine 1. When crimping, place the joint in the center of the mold as much as possible, and do not press on the hexagonal nut. 2. Prevent tools and other foreign objects from entering the press head. 3. After the work is completed, the eight mold bases must be opened to the maximum extent, so that the spring can be in the open state and the spring can be maintained, and the oil cylinder is also in the pressure relief state to extend the life of the oil seal.

Working principle of hose crimping machine

Working principle of hose crimping machine The hose crimping machine is a hydraulic equipment used to crimp the pipe assembly. It applies the crimping force to the matched metal joints through the mold of the crimping machine, and firmly crimps the metal joints on the matched high-pressure oil pipes for construction machinery or automobiles. The brake hose, engine oil hose, air-conditioning hose and power hose are installed. The crimping machine is suitable for the crimping of various mechanical high and low pressure oil pipes, air pipes, water pipes, cable joints, automobile air conditioning pipes, automobile power steering pipes, oil pipes, gasoline supply pipes, as well as construction accessories and daily hot water pipes. It is widely used Vehicles, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. The pressure is accelerated in the nozzle by the main oil pump, thereby forming a negative pressure in the mixing chamber of the nozzle. Due to the entrainment of the negative pressure and the free jet, the oil in the mixing chamber in the oil tank is continuously brought into the diffuser tube. The mixed oil flow is decelerated and boosted in the diffuser tube and then sent to the main oil pump or lubricated oil for the bearing. The oil injector is one of the main equipment of the centrifugal oil pump oil supply system. It is mainly composed of a nozzle, a mixing chamber and a diffuser tube. The pipe pressing machine drives the steel pipe to rotate through mechanical transmission and heats it with flame at one end of the steel pipe. When a certain temperature is reached, the heated steel pipe head is driven by a forming die until it reaches the required shape. The structure of the hose crimping machine: Weld a site with channel steel, and the power end is equipped with a motor, a reducer, and a chuck (for pipe clamping, it can be replaced by a lathe chuck). A support base (openable) is installed at the other end, and a heating ring is fixed on the outer end of the support base (8-10 nozzles, welded to a copper pipe ring by gas welding). *On the outside is a movable bracket with an alloy mold installed on it. How to use: Fix the tube on the tube press and turn on the heater (ring). After the temperature is reached, the alloy mold is pushed, and the shape of the tube head meets the requirements. The whole process takes about 15 minutes. With the slowdown and delay of infrastructure projects such as real estate and road and bridge construction, the crimping machine industry is affected by the decline in overall economic growth. In the future, under the premise of maintaining overseas markets, it will increase independent product innovation and continue to improve the research and development of crimping machines and pipe crimping machines. Invest in efforts to create value for products and services and maintain a leading position in the industry.

About crimping machine

About crimping machine 1. Visually observe 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 pipeline design of the oil station is reasonable; whether there is oil leakage at the connection. If the above passes the visual inspection, you can proceed to the next step. 2. Turn on the device after connecting it to the power source, and listen to whether the device's operating sound is normal. If there is abnormal noise, it is usually 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. 3. Measurement: Finally, the main parameters of the equipment are measured 3.1 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. 3.2 Mount 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. 3.3 The hardness of the mold base and the 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. 3.4 The last is to inspect the eight-petal uniform indexing of the mold base of the equipment and the flushness of the mold. 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 manufacturer explains the precautions for the installation of the shrinking machine: First, add 79 liters of Changcheng brand 46# anti-wear hydraulic oil. If the room temperature is lower than 10℃, add 10 transformer oil. Connect the power supply according to the requirements of the machine, make the rotation direction of the motor consistent with the rotation direction mark on the motor, and make grounding protection. Second, adjust the ruler The ruler is used to adjust the size of the crimping amount. Adjust the withholding amount clockwise to decrease, and adjust the withholding amount counterclockwise to increase. The ruler is connected with the cylinder end cover by three hexagon socket screws and three springs on the ruler seat. Pull the ruler by hand (perpendicular to the cylinder end cover direction), and it should be able to leave the cylinder end cover flexibly, and then rest on the spring force to recover. , It should be carefully checked each time before starting up.
