Description

TECHNICAL FIELD

[0001] The present application relates to the field of hydraulic pipes, in particular to a hydraulic pipe crimping anti-bending deformation device. BACKGROUND

[0002] The hydraulic pipe crimping anti-bending deformation device is an auxiliary equipment for preventing pipe body bending deformation in the hydraulic pipe crimping process.

[0003] By installing the anti-bending clamping plate at both ends of the hydraulic pipe crimping device, the force balance of the crimping pipe is achieved at the two ends of the clamp in the vertical direction, and the two ends of the clamp are fixed on a straight line in the horizontal direction, thereby reducing the possibility of bending of the hydraulic pipe during the crimping process.

[0004] For a certain length of ground wire, when hydraulic crimping is performed, the ground wire needs to be moved to crimp the connection at different positions, and when local crimping is performed, the force at the edge of the crimping position disappears, causing a turning at the edge of the crimping position, resulting in bending at the edge due to unbalanced force, and requiring secondary correction after crimping, increasing the workload and easily causing hydraulic pipe wear. SUMMARY

[0005] The present application aims to solve the problems in the prior art and provides a hydraulic pipe crimping anti-bending deformation device.

[0006] In a first aspect, the present application provides a hydraulic pipe crimping anti-bending deformation device, comprising a processing table, further comprising:

[0007] Two fixed plates symmetrically fixed on both sides of the top of the processing table;

[0008] Two first air cylinders symmetrically fixed on the opposite sides of the two fixed plates, and the extension rods of the two first air cylinders both penetrate the fixed plates;

[0009] Two first moving frames respectively fixed on the end portions of the extension rods of the two first air cylinders;

[0010] An anti-bending extrusion assembly installed between the two first moving frames for crimping the workpiece and guiding and connecting the crimping edge to reduce bending deformation;

[0011] Two drive assemblies symmetrically installed at both ends of the top of the processing table for driving the movement of the workpiece;

[0012] The workpiece to be processed is placed on the fixed plate, and the workpiece can be moved to the next position for crimping after crimping at one position by driving the workpiece to move through the drive assembly, so as to crimp the workpiece at each position;

[0013] The first cylinder can drive the first moving frame to move through the telescopic rod after starting. After the two first moving frames are aligned, the anti-bending extrusion assembly can be started to press the workpiece and guide and connect the edges of the press joint position to make the edges of the press joint position smooth and connected, thereby preventing the edges of the press joint position from being suddenly stressed and unbalanced to cause bending deformation of the edges of the press joint position of the workpiece.

[0014] Preferably, the anti-bending extrusion assembly comprises:

[0015] Two groups of clamping plates are arranged inside the two first moving frames, respectively.

[0016] Two groups of second cylinders are fixed on the outer walls of the two first moving frames, respectively, and the second cylinders are used to drive the first moving frames to move to press the workpiece.

[0018] The second cylinder can drive the clamping plate to move after starting. When the clamping plate moves, it is extruded on the surface of the workpiece to press the workpiece. The two ends of the clamping plate are provided with guide blocks, and the guide blocks and the clamping plate are provided with guide arc surfaces. When the clamping plate is pressed on the workpiece, the edges of the press joint position are guided by the guide blocks, the stress is gradually reduced along the extension of the guide blocks, and the extrusion radius is gradually increased, so that the edges of the press joint position of the workpiece form a smooth inclined plane, thereby preventing the sudden disappearance of stress from causing stress imbalance and bending deformation, thereby reducing the bending deformation of the workpiece during the press joint process.

[0019] Preferably, the anti-bending extrusion assembly further comprises:

[0020] The guide block is rotatably connected to the end edge of the clamping plate through the end edge;

[0024] The third cylinder drives the guide block to move through the telescopic rod, so that the guide block is flipped to be inclined upward, so that the guide block is no longer attached to the workpiece, thereby being capable of switching to the effect of only pressing the pressing position of the workpiece. When the third cylinder pushes the guide block to flip to be attached to the clamping plate, the guide block can be switched to be connected to the end of the clamping plate, so that the edge can generate a connection surface by extrusion to avoid the deformation of the soil due to the disappearance of stress.

[0025] The telescopic rod of the third cylinder moves to drive the sliding block to move.

[0034] After the guide block is inserted into the clamping plate, the electromagnet is powered on to start, so that the electromagnet and the magnet are opposite to each other, thereby generating a magnetic driving force on the magnet, so that the magnet is inserted into the inside of the limiting groove, thereby limiting the insertion of the guide block and the clamping plate, when the limiting needs to be cancelled, the electromagnet is reversely powered on, so that the magnetic pole direction of the electromagnet is switched, thereby the electromagnet generates a magnetic attraction force on the magnet, thereby pulling the magnet out of the inside of the limiting groove, thereby cancelling the limiting;

[0035] The limiting clamping of the guide block and the clamping plate after the insertion makes the abutting surface of the guide block and the clamping plate provided with a plurality of limiting points, thereby facilitating the dispersion of the force between the guide block and the clamping plate, and avoiding the breakage caused by the force acting on the rotating connection of the guide block and the clamping plate, thereby improving the connection stability of the guide block and the clamping plate.
