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.

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 surface of the piston front end.

A replaceable tooth plate is connected to the inner surface of the slider; where the piston rod and the rear end cover contact, where the outer wall of the piston contacts the inner wall of the cylinder liner, where the sealing sleeve contacts the inner wall of the cylinder liner, and the seal sleeve contacts the outer wall of the front end of the piston Seals are provided everywhere.
The beneficial effects of the present invention are: because the structure of the locking assembly of the present invention is a cylinder liner with a hollow structure as the main body, the piston and the piston rod arranged in the cylinder liner are also hollow structures, and the locking assembly has two ends In this way, the pipe to be locked can pass through the middle of the locking assembly, and the original only end-face locking is changed to a through-lock. In addition, the piston, the cylinder liner and the sealing sleeve form an annular return oil chamber , The piston rod and the piston, the cylinder liner and the rear end cover constitute an annular sealing process oil chamber. When locking, the end surface of the pipe to be locked is covered with a lock skin, and the front end of the locking assembly is extended to remove the other pipe from the lock. The rear end cover of the assembly is extended, the two pipes are connected together, and the piston is driven by hydraulic action to directly lock the pipes. In this way, the pipe connection is easily realized, and for large end-face parts and the middle of the pipe It can be locked in one position. In addition, the tube locking machine has a simplified structure and a light body, only one-third of the same product, less materials, and a half of the production cost.
