Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending processing, in particular to an anti-wrinkle device for pipe bending processing. Background Art

[0002] As the name suggests, pipe bending is a process of bending pipes. It is usually done with a pipe bender, which can be roughly divided into fully automatic pipe bender and manual pipe bender. During the pipe bending process, the wall thickness of the pipe will change due to the bending. In particular, wrinkles will form when the wall thickness of the pipe becomes thicker. In order to prevent wrinkles, anti-wrinkle plates are currently used to prevent wrinkles during the processing.

[0003] The anti-wrinkle plate will produce wear and deformation during use, and needs to be inspected and replaced after a period of use. The traditional installation method is mostly to fasten it with bolts, which is inconvenient during disassembly and installation. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses an anti-wrinkle device for pipe bending processing, and the technical scheme adopted is that it includes a pipe bending guide die, a pipe bending clamp die, a clamp die seat, a clamp die seat mounting track, a rotating screw and a screw motor. The above belongs to the common prior art, and the remaining parts also include an anti-wrinkle mounting seat, a mounting frame, a penetration portion, a top clamping structure, a stabilizing portion, an internal mounting frame, a top blind hole, a top inclined surface, an anti-wrinkle plate, a side convex plate and an internal adjustment mechanism. One side of the pipe bending guide die is a pipe bending clamp die installed through the clamp die seat, and the clamp die seat is cooperated with the clamp die seat mounting track and installed with the rotating screw therein, and the rotating screw is driven by the screw motor. The pipe bending guide die is fixed on the plate body where the clamp die seat mounting track is located, and a rotating mechanism is arranged at the lower end of the plate body, and the rotation center of the rotating mechanism coincides with the center of the circle of the pipe bending guide die. The rotating mechanism adopts a stepping motor or other existing rotating equipment, which can drive the bending guide die box and the bending clamp die to rotate to realize the bending of the pipe fitting. The left side of the plate body where the clamp seat mounting track is located is a fixed anti-wrinkle mounting seat, and the mounting frame is fixed on the anti-wrinkle mounting seat. The front side of the mounting frame has a through portion, a top clamping structure is arranged on the top, and a stabilizing portion is arranged on the inner bottom surface. The internal mounting frame is installed through the stabilizing portion, and its top surface has a top inclined surface, and a top blind hole is opened on the horizontal part on one side of the top inclined surface. An internal adjustment mechanism is arranged in the internal mounting frame, and the side convex plates integrally formed on the left and right sides of the anti-wrinkle plate are installed in cooperation with the internal adjustment mechanism. The anti-wrinkle plate is initially set to three layers. When the initial outermost anti-wrinkle plate is worn, it can be directly removed by operating the internal adjustment mechanism and the next anti-wrinkle plate can be adjusted to the processing position.

[0005] As a preferred technical solution of the utility model, the top clamping structure includes a top plate, a tensioning spring and a clamping shaft. A hole is opened on the upper surface of the mounting frame, and the clamping shaft passes through the hole. A top plate is fixed on the top of the mounting frame, and a tensioning spring is fixed on the upper surface of the mounting frame. The upper end of the tensioning spring is fixedly connected to the top plate, and the whole is sleeved outside the clamping shaft. Under the action of the tensioning spring, the initial position of the clamping shaft penetrates into the mounting frame, and its lowest point is higher than the lowest point of the top inclined surface. Therefore, in the process of pushing the internal mounting frame in, the clamping shaft can be pushed up by the gradual movement of the top inclined surface until the top blind hole 7 reaches below the clamping shaft, at which time the clamping shaft will extend into it to achieve clamping.

[0006] As a preferred technical solution of the utility model, the stabilizing part includes a stabilizing T-slot, a bottom T-block and a T-block through hole. A stabilizing T-slot is opened on the bottom surface of the mounting frame, and two shafts are fixed in the stabilizing T-slot. A bottom T-block is fixed to the lower part of the internal mounting frame, and a T-block through hole is opened in the bottom T-block. The bottom T-block is placed in the stabilizing T-slot and is mounted on the shaft through the T-block through hole, so that the movement of the internal mounting frame is more stable.

[0007] As a preferred technical solution of the present invention, the bottom T-block is connected to the installation frame by welding.

[0008] As a preferred technical solution of the utility model, the internal adjustment mechanism includes a guide shaft, an adjusting screw and a knob. Two guide shafts are respectively fixed at the four corners of the inner side wall of the internal mounting frame, and two adjusting screws are rotatably installed. The adjusting screws are driven by the knob. The outer wall of the knob has a protective groove. The side convex plates integrally formed on both sides of the anti-wrinkle plate are respectively movably mounted on the guide shaft and are installed in cooperation with the adjusting screw. The position of the anti-wrinkle plate can be adjusted by rotating the adjusting screw when the knob is rotated.

[0009] The beneficial effects of the utility model: through the top clamping structure, the stabilizing part, the top blind hole and the top inclined surface, the internal installation frame can be quickly installed, and the position can be clamped after it is pushed into the installation frame, which is convenient for installation. Multiple anti-wrinkle plates are pre-arranged through the internal adjustment mechanism, and the outermost anti-wrinkle plate can be directly replaced after it is worn, and the operation is simple.
