Description

Technical Field

[0001] This utility model relates to the field of metal corrugated pipe processing equipment, and in particular to an automatic forming machine for prestressed metal corrugated pipes. Background Technology

[0002] Metal corrugated pipes are formed by corrugating and winding steel strips. The metal corrugated pipe forming machine consists of several main parts, including a frame, corrugating structure, winding structure, and cutting structure. The steel strip surface is corrugated, then wound into a tubular shape, and finally cut.

[0003] Existing metal corrugated pipe forming machines all use traditional, relatively narrow steel strips (around 40mm) for processing, which is slow and cannot process wider steel strips (around 80mm). This is because uneven stress on the steel strip during the corrugation and winding process with wider strips can easily affect the forming stability. Therefore, this application provides an automatic prestressed metal corrugated pipe forming machine to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic prestressed metal corrugated pipe forming machine. This machine solves the problem that existing metal corrugated pipe forming machines cannot process thicker steel strips and have inconsistent forming quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic forming machine for prestressed metal corrugated pipes, comprising a frame, a corrugating structure, a forming structure, and a cutting structure, wherein the corrugating structure, the forming structure, and the cutting structure are all disposed on the upper end face of the frame;

[0006] The wave compression structure includes a feeding motor and a wave compression box. The output end of the feeding motor is connected to the wave compression box via gears. A wave compression box base is fixedly installed at the bottom of the wave compression box. A first adjusting seat is installed at the lower end of the wave compression box base. A rotating seat is connected to the center of the bottom end of the first adjusting seat. The rotating seat is connected to the frame.

[0007] The forming structure includes an active winding motor, a mounting plate, a winding spindle, a first-stage adjuster, a second-stage adjuster, and a third-stage adjuster. The mounting plate is fixed to the upper surface of the frame. The winding spindle and the active winding motor are respectively located on the front and rear sides of the mounting plate. The output end of the active winding motor is connected to the rear end of the winding spindle. The first-stage adjuster, the second-stage adjuster, and the third-stage adjuster are all fixed on the front side of the mounting plate and located on the outside of the winding spindle.

[0008] The cutting structure includes a slide rail, a second adjusting seat, a first cylinder, a process adjusting seat, a second cylinder, and a cutting motor. The slide rail and the first cylinder are fixed side by side on the frame. The second adjusting seat is slidably mounted on the slide rail. The output end of the first cylinder is connected to the bottom end of the second adjusting seat. The process adjusting seat is mounted on the second adjusting seat. The cutting motor is mounted on the upper end of the process adjusting seat and the bottom is fixedly connected to the second cylinder. The movable end of the second cylinder is fixed to an inner side wall of the process adjusting seat. A cutting wheel is fixedly mounted on the output end of the cutting motor.

[0009] Furthermore, the pressure box includes a lower box and several upper boxes disposed at the top of the lower box. A gear set is disposed on one side of the lower box and several upper boxes. Several feeding auxiliary wheels are disposed at the front end of the interior of the lower box. Pressure wheels are disposed in several upper boxes and the lower box directly below, and one end of the central shaft of several pressure wheels is connected to the gear set.

[0010] Through the above technical solution, the pressure rollers set in the pressure box can press and form thick steel strips into waves. Then, the feeding motor, in conjunction with the gear set, drives the steel strip to be transmitted to the main shaft of the forming structure at a stable speed. During this process, the steel strip is under stable force, which can ensure the stability of the forming process.

[0011] Furthermore, the pressure roller is configured as a cylinder with corrugated protrusions on its surface.

[0012] Furthermore, the primary adjuster includes a mounting base, a steering rod, and an adjusting wheel. The mounting base is fixed to the mounting plate, the middle part of the steering rod is fixed to the other end of the mounting base, and the adjusting wheel is located on the inner end of the steering rod.

[0013] Furthermore, the secondary regulator, tertiary regulator and primary regulator have the same structure, but the adjustment wheels of the three regulators are constructed differently;

[0014] Through the above technical solution, the steel strip after pressure wave can be wound onto the winding spindle and formed by adjusting the guidance of the three adjusters.

[0015] Furthermore, a cooling gun is fixedly installed on the front side of the mounting plate, and the cooling gun can be connected to an external water source or a water supply tank can be installed inside the frame.

[0016] The above technical solution allows the cooling gun to cool the corrugated pipe during the winding process after being connected to water.

[0017] This utility model has the following beneficial effects:

[0018] 1. The corrugating structure provided in this application corrugates the steel strip through a corrugating box. The corrugating process is achieved by the cooperation of upper and lower corrugating rollers set in the box, which can quickly and stably press corrugations into the steel strip. It can also process wider steel strips quickly. Moreover, the operation is driven by a feeding motor, which can ensure that the steel strip moves stably during the corrugating process and is subjected to uniform force during the process of moving from the corrugating box to the winding spindle, thus ensuring stable forming.

[0019] 2. The automatic molding machine proposed in this application has a high degree of automation during operation. The processes of wave pressing, molding, and cutting are all driven by motors. It can be started with one button by designing a controller, without the need for manual intervention, and can produce automatically. Attached Figure Description
