[0042] The crimping device of this embodiment can move horizontally to realize the crimping operation of different positions of the butt joint pipe. Its structure includes a crimping pliers 11, and a crimping die is arranged on the crimping pliers 11; a guide rail is arranged on the main frame 6, and the bottom of the crimping pliers 11 is fixedly arranged on the crimping pliers moving base, and the crimping pliers moving base is slidably arranged on the guide rail; a crimping screw assembly 9 is arranged on the inner side of the guide rail, and the crimping screw assembly 9 includes a screw and a screw nut, and the screw nut is fixedly connected to the crimping pliers moving base, so that the crimping screw assembly 9 can drive the crimping pliers 11 to move horizontally along the guide rail.

[0043] When the present invention is working, the driving motor is switched to be connected with the crimping screw assembly 9; the demoulding cylinder 14 will move up and down according to the working state, driving the demoulding movable frame to move up and down to adjust the center position of the wire. When crimping, the demoulding cylinder 14 will drive the demoulding movable frame to move upward with the lower die of the crimping pliers 11 to ensure that the center of the wire coincides with the closing line when the mold is closed. The driving motor drives the screw to drive the crimping pliers 11 to move left and right to complete the crimping work. When demoulding, the demoulding cylinder 14 will drive the demoulding movable frame to move downward with the lower die to ensure that the connecting pipe is separated from the upper and lower dies.

[0044] Specifically, the crimping pliers 11 include a pliers seat with a U-shaped groove, the pliers seat is fixedly arranged on the crimping pliers 11, and the die is located in the U-shaped groove of the pliers seat; a hydraulic cylinder 119 is arranged at the bottom of the pliers seat, and the hydraulic cylinder 119 is connected to the pump station through the oil port 118; the piston 117 of the hydraulic cylinder 119 is connected to the lower die through the fixed pin 116, and the upper die 114 is fixed to the mold fixing block 113 at the top of the pliers seat, and the top of the mold fixing block 113 is provided with a top cover 112, and the top cover 112 is provided with a handle 111 for easy movement.

The pressing die is used in conjunction with the connecting pipe fastener 7 and can be used as a connecting pipe clamp, thereby improving the use efficiency of the crimping pliers 11 and increasing the applicability of the crimping pliers 11.

[0045] When the present invention is used, the PLC program automatically controls the pump station to fill hydraulic oil into the hydraulic cylinder, drives the lower die to move up and down, and crimps the connecting pipe with the wire inserted between the upper die and the lower die. The mold is moved by the crimping screw assembly 9 to achieve crimping of different positions of the connecting pipe, and the demoulding cylinder 14 is controlled to drive the wire and the connecting pipe to move up and down to assist in demoulding. After the crimping of the steel connecting pipe is completed, the above-mentioned method is used to crimp the aluminum connecting pipe, and finally the threading and crimping of the connecting pipe are completed.

The moving plate 5 moves with the pipe threading screw assembly 4 to realize the action of wire threading. The moving plate 5 can be repeatedly operated until the wire is in place. When threading the steel connecting pipe, the wire must first be clamped in the right wire fastener 8, and then manually inserted into the steel connecting pipe, and then the wire fastener 8 is fixed, and finally the wire installed on the moving plate 5 is moved to penetrate into the steel connecting pipe; When the driving motor drives the crimping screw assembly 9, the equipment can perform crimping work, the lower pressing film 115 of the crimping pliers 11 is connected to the pin shaft of the jacking cylinder, the lower pressing die can move with the cylinder, and a wire mounting plate is provided on the demoulding cross bar 13, and a demoulding wire fastener 12 is provided on the top of the wire mounting plate. The demoulding cylinders 14 on both sides will drive the demoulding wire fasteners 12 on the demoulding cross bar 13 and the wires fixed on the demoulding wire fasteners 12 to move up and down. There is a stroke difference between the demoulding cylinder 14 and the crimping pliers 11, thereby realizing crimping and demoulding. During crimping, the PLC program will automatically control the motor to drive the crimping screw assembly 9, drive the crimping pliers 11 to perform crimping and mold shifting, and the PLC will deploy the pump station to realize the crimping and demoulding actions, thereby realizing the full automation of the crimping process.
