Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a pipe bending machine with a correction structure. Background Art

[0002] A pipe bender is a machine that can bend a pipe. Based on the principle of vector pipe bending and controlled by a microcomputer, it can complete any spatial three-dimensional pipe shape required by the user. It is an important processing equipment for modern bending and shaping. The existing pipe bender has a relatively simple structure. Through the guide structure, the base and the bending structure set on the base, the pipe body is transported to the pipe bending structure through the guide structure for bending. However, the guide structure drives the pipe bending structure to transport the pipe body forward, and the pipe body is prone to hanging and jumping, thereby affecting the effect of the pipe bending structure on the pipe bending process.

[0003] According to a disclosed pipe bending machine (publication number: CN 220161118 U), in the above application, the brake wheel is rotated forward or reversely to rotate the threaded rod, thereby driving the slide plate and the movable plate to approach and move away from the clamping plate, thereby adjusting the distance between the movable plate and the clamping plate, and can clamp and fix pipes of different sizes, and increase the friction force through the convex strips to avoid the movement of the pipe body during the bending process. By rotating the rotating wheel and under the guidance of the limit rod, the lead screw drives the pressure plate to move downward and contact the surface of the pipe body, thereby avoiding the phenomenon of hanging and jumping of the pipe body during the bending process.

[0004] However, in actual use, when bending pipes, due to the simple fixed structure, the hollow pipe may easily tilt at one end due to the lack of pressure restriction, thus affecting the bending operation. In view of this, we propose a pipe bending machine with a correction structure. Utility Model Content

[0005] The purpose of the utility model is to provide a pipe bending machine with a correction structure to solve the problems raised in the above background technology.

[0009] The main threaded rod, the notched hollow column is threadedly connected to the main threaded rod, and the inner wall of the notched hollow column is fixed with a spring.

[0010] Preferably, the clamping assembly comprises a fixing plate fixedly mounted on the surface of the machine body, a through slot provided on the surface of the machine body, and a capped threaded rod fixedly mounted on the inner wall of the machine body.

[0011] Preferably, the fixing assembly includes a fine threaded rod threadedly connected to the upper surface of the handle, the fixing rod is slidably installed on the surface of the handle, and the fixing rod and the fine threaded rod pass through the handle, and the bending rod is fixedly installed on the lower surface of the handle.

[0012] Preferably, the upper surface of one end of the hollow column with a missing corner has a semi-arc notch, and the curvature of the semi-arc notch matches the arc of the circular groove, and the diameter of the circular groove matches the diameter of the bent pipe. A movable groove is provided at the lower end of the hollow column with a missing corner, and the support column is clamped in the movable groove.

[0013] Preferably, the number of the notched hollow columns is set to two, the main threaded rod passes through one of the notched hollow columns, and a half-length thread groove is opened inside the other notched hollow column.

[0014] Preferably, the surface of the threaded sleeve is provided with threads, and the curvature of the sleeve shell on the lower surface of the threaded sleeve is matched with the curvature of the left end of the flower-shaped clamping seat.

[0015] Compared with the prior art, the utility model provides a pipe bending machine with a correction structure, which has the following beneficial effects:

[0016] 1. The pipe bending machine with a correction structure is designed to prevent the hollow pipe from easily tilting up due to unstable reinforcement during bending, which is not conducive to the bending of the hollow pipe. A clamping mechanism is provided, and the hollow pipe is in a circular groove. The corner-less hollow column is moved by the main threaded rod to fix the hollow pipe, so that the hollow pipe is in a horizontal straight line position, which better fits the arc groove of the hollow pipe on the bending wheel, and the hollow pipe is corrected, thereby ensuring the bending accuracy of the hollow pipe and making the bent product better.

[0017] 2. For the pipe bending machine with a correction structure, when the pipe is being bent, the bending trajectory of the hollow pipe may cause the hollow pipe to move left and right. In order to strengthen the fixation of the hollow pipe, a flower-shaped clamping seat is provided, and the threaded sleeve is twisted so that the arc surface of the lower surface of the threaded sleeve rotates and passes through the arc-shaped mouth of the upper surface of the flower-shaped clamping seat for clamping, thereby completing the fixation of the joint and allowing the hollow pipe to be better bent at the groove of the bending wheel without deviation.

[0025] In the embodiment of the utility model, a vertical plate 409 is fixedly installed on the upper surface of the body 1 so that the base of the correction mechanism 4 maintains stability during correction. A circular groove 404 is provided on the surface of the vertical plate 409 to facilitate the penetration of the hollow tube and maintain the fixation of the hollow tube. A flower-shaped clamping seat 403 is fixedly installed on the outer side of the vertical plate 409 to better fix the hollow tube. A support plate 401 is fixedly installed on the outer side of the vertical plate 409. The surface of the support plate 401 is threadedly connected to the threaded sleeve 402 to better fix the threaded sleeve 402 and prevent the threaded sleeve 402 from falling off. The interior of the vertical plate 409 is slidably connected to a hollow column 410 with a missing corner. A square groove is provided at one end of the hollow column 410 to facilitate the subsequent placement of a spring 407 to maintain the stability of the mechanism. The hollow column 410 with a missing corner is threadedly connected to the main threaded rod 405, and the spring 407 is fixedly installed on the inner wall of the hollow column 410 with a missing corner.
