Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe production and processing, in particular to a steel strip bending and forming integrated machine. Background Art

[0002] Steel belt pipe is a new type of pipeline material. Usually, the steel belt pipe uses high-density polyethylene (HDPE) as the matrix, and the steel belt coated with adhesive resin on the surface is formed into a waveform as the main supporting structure, and is wound and compounded with polyethylene material to form an integral double-wall corrugated pipe. It has excellent chemical stability, aging resistance and environmental stress cracking resistance.

[0003] The processing of steel strips into pipes generally goes through the steps of "bending" and "shaping". The "bending" is generally performed by a bending machine, which bends the steel strips into a set shape to change the shape of the steel strips to meet the use requirements of the pipes. The "shaping" is generally performed by a roll forming machine, which improves its final form and enhances the performance requirements of the steel strips. Since the "bending" and "shaping" steps require the use of separate equipment, when the steel strips are subjected to the "shaping" process after "bending", the staff will take out the bent steel strips and put them into the "shaping" equipment for shaping processing. For this purpose, the bent steel strips need to be transferred manually, which increases production costs and significantly reduces production efficiency. Utility Model Content

[0004] The utility model aims to provide an integrated steel strip bending and forming machine to solve the problem that the existing steel strip bending machine and forming machine operate separately, resulting in increased production costs and reduced production efficiency.

[0005] In order to solve the above problems, the technical solutions provided are as follows:

[0006] A steel strip bending and forming integrated machine comprises a bending part and a forming part, wherein the bending part comprises a reeling roller, a squeezing roller, a traction roller, a guide roller and a guide block, wherein the reeling roller, the squeezing roller and the traction roller are on the same horizontal line, the guide roller is behind the traction roller and is tilted, the guide block is at the lower side of the guide roller and is tilted, and a bent steel strip guide path is provided in the guide block; the forming part comprises a bent steel strip winding frame and a shaping roller, the shaping roller is in the gap at the bottom end of the bent steel strip winding frame, and the forming part is on one side of the bending part.

[0007] The basic principle of the above technical solution is that the steel strip is released from the unwinding roller after being pulled by the traction roller of the bending part, and is initially extruded by the extrusion roller, guided and bent by the guide roller, and guided again by the guide path in the guide block so that the bent steel strip is spiraled. The spiraled bent steel strip is extruded and shaped by the shaping roller of the forming part, and then spirally wound onto the bending steel strip winding frame, thereby completing the bending and shaping of the steel strip.

[0008] The beneficial effect of the above technical solution is that compared with the existing steel strip bending and forming which requires the use of a steel strip bending machine and a forming machine respectively, the present technical solution bends the steel strip first in the bending part and then in the forming part for shaping. After the bending is completed, the steel strip does not need to be taken out of the bending part for transfer, but can directly flow to the shaping part for shaping, which saves manpower and improves the efficiency of the steel strip bending and forming.

[0009] Furthermore, the squeezing rollers include a vertical squeezing roller with an axis arranged in the vertical direction and a horizontal squeezing roller with an axis arranged in the horizontal direction, and the horizontal squeezing roller is located before the vertical squeezing roller. The steel strip is first squeezed through the horizontal squeezing roller and then through the vertical squeezing roller for preliminary shaping, and the initially formed steel strip is convenient for subsequent uniform bending through the guide roller.

[0010] Furthermore, the unwinding roller, the squeezing roller, the traction roller, the guide roller and the guide block are all rotatably connected to the frame. All rollers rotatably connected to the frame are convenient for installation and disassembly and replacement, and rollers of different sizes can be disassembled and replaced to be suitable for bending steel strips of different sizes.

[0011] Furthermore, the curved steel strip winding frame includes two support plates and a plurality of support rods, the two ends of the plurality of support rods are supported between the two support plates respectively, the plurality of support rods are arranged in a ring shape, and the curved steel strip is wound on the support rods arranged in a ring shape. By winding the curved steel strip on the plurality of support rods arranged in a ring shape, not only can the curved steel strip be prevented from being deformed under the action of gravity, but also the subsequent extrusion process into a steel strip corrugated tube can be facilitated.

[0012] Furthermore, the support plate is circular, and a plurality of mounting holes evenly arranged in a circular shape are provided on the outer periphery of the support plate, and the ends of the support rods are inserted into the mounting holes. The support rods are inserted through the mounting holes, which is convenient for disassembly and replacement.

[0013] Furthermore, the side of the shaping roller is rotatably connected with a connecting rod, and the other end of the connecting rod away from the shaping roller is fixedly connected to the frame. The shaping roller is in the gap of the support rod, and the bent steel strip is wound on the support rod after passing through the shaping roller. Before the bent steel strip is wound on the support rod, it first passes through the shaping roller, which can not only shape the bent steel strip, but also correct the steel strip that is bulged or bulged during the bending process.
