Description

Technical Field

[0001] This utility model relates to the field of steel-plastic composite pipe production technology, specifically to a cutting device for steel-plastic composite pipe production. Background Technology

[0002] Steel-plastic composite pipe is a galvanized steel pipe with an inner plastic coating. It is made by using seamless steel pipe or welded steel pipe as the base pipe and coating the inner wall with high adhesion, anti-corrosion, food-grade hygienic polyethylene powder coating or epoxy resin coating. It is an upgraded product of traditional galvanized pipe. Steel-plastic composite pipe needs to be cut and processed by cutting equipment during the production process.

[0003] However, existing cutting devices generally adopt a single-piece sequential feeding operation mode, requiring operators to manually position and clamp each pipe, resulting in long idle time and reduced work efficiency. In addition, slippage is prone to occur during the cutting of steel-plastic composite pipes, affecting the cutting quality. Therefore, a cutting device for the production of steel-plastic composite pipes is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for the production of steel-plastic composite pipes, so as to solve the problems of reduced work efficiency caused by the common single-piece feeding operation mode, and the slippage of steel-plastic composite pipes during the cutting process, which affects the cutting quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for producing steel-plastic composite pipes, including a cutting table, a frame on the cutting table, and a longitudinally movable cutting device installed on the frame;

[0006] Two sets of fixed clamping plates are symmetrically arranged on both the front and rear sides of the cutting table, and two sets of movable clamping plates are arranged on the cutting table between the two sets of fixed clamping plates.

[0007] The cutting table is equipped with a drive assembly for driving the two sets of movable clamping plates to move synchronously.

[0008] Preferably, the cutting device includes a lead screw module mounted longitudinally on a frame, the movable end of the lead screw module is connected to a mounting base, a drive motor is fixed on the mounting base, and the output shaft of the drive motor is connected to a cutting blade.

[0009] Preferably, the driving assembly includes a cavity disposed inside the cutting table, and a threaded rod is rotatably mounted inside the cavity; a forward and reverse motor for driving the threaded rod to rotate is mounted on the cutting table, a slider is threadedly connected to the threaded rod, and a guide rod penetrating the slider is also provided inside the cavity;

[0010] The upper surface of the cutting table has several strip-shaped openings, and two sets of movable clamping plates pass through the corresponding strip-shaped openings and are fixedly connected to the slider.

[0011] Preferably, each set of fixed clamping plates includes multiple clamping units evenly distributed along the length of the cutting table, and the clamping end of each fixed clamping plate is configured as a V-shaped clamping opening;

[0012] Each set of movable clamping plates includes multiple clamping units corresponding to the fixed clamping plates, and the clamping ends on both sides of each movable clamping plate are configured with V-shaped clamping openings.

[0013] Preferably, the clamping end surfaces of both the fixed clamping plate and the movable clamping plate are provided with anti-slip rubber pads.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a cutting device for the production of steel-plastic composite pipes. Through the coordinated action of the fixed clamping plates arranged symmetrically at the front and rear and the movable clamping plate in the middle, two cutting stations are formed. This allows the operator to feed another pipe while the pipe at one station is being cut, greatly reducing the idle waiting time of the equipment and significantly improving the cutting efficiency.

[0015] Both the fixed and movable clamping plates employ a multi-set V-shaped clamping unit design, coupled with anti-slip rubber pads, increasing the clamping points with the pipe and preventing the pipe from rotating or moving axially during the cutting process, ensuring a smooth cut without surface scratches.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 This utility model provides a technical solution: a cutting device for producing steel-plastic composite pipes, including a cutting table 1, a frame 2 on the cutting table 1, and a support frame at both ends of the cutting table 1. The top of the two support frames has a mounting plate, and a triangular reinforcing plate is provided between the mounting plate and the support frame. A longitudinally movable cutting device 3 is installed on the frame 2. The cutting device 3 includes a screw module 31 longitudinally installed on the frame 2. The moving end of the screw module 31 is connected to a mounting base 32. A drive motor 33 is fixed on the mounting base 32. The output shaft of the drive motor 33 is connected to a cutting blade 34. During the cutting process, the drive motor 33 is started to drive the cutting blade 34 to rotate, and the screw module 31 drives the mounting base 32, the drive motor 33 and the cutting blade 34 to move back and forth, so that the cutting blade 34 moves repeatedly between two cutting stations, thereby realizing the cutting of steel-plastic composite pipes.

[0021] Specifically, two sets of fixed clamping plates 4 are symmetrically arranged on both the front and rear sides of the cutting table 1. Each set of fixed clamping plates 4 includes multiple clamping units evenly distributed along the length of the cutting table 1, and the clamping end of each fixed clamping plate 4 is set as a V-shaped clamping opening. The V-shaped clamping openings of the two sets of fixed clamping plates 4 on the front side of the cutting table 1 and the V-shaped clamping openings of the two sets of fixed clamping plates 4 on the rear side of the cutting table 1 are located on the same side close to each other. Two sets of movable clamping plates 5 are arranged on the cutting table 1 between the two sets of fixed clamping plates 4; each set of movable clamping plates 5 includes multiple clamping units corresponding to the fixed clamping plates 4. Furthermore, each movable clamping plate 5 has V-shaped clamping openings on both sides. The clamping ends of both the fixed clamping plate 4 and the movable clamping plate 5 are equipped with anti-slip rubber pads 7. These anti-slip rubber pads 7 increase the friction between the pipe and the clamping material, effectively preventing pipe rotation or axial movement during cutting. The symmetrically arranged fixed clamping plates 4 and the movable clamping plate 5 work together to form two cutting stations. This allows the operator to feed another pipe while one is being cut at a station, significantly reducing equipment idle time and greatly improving cutting efficiency. The use of multiple V-shaped clamping units in both the fixed clamping plates 4 and the movable clamping plates 5, combined with the anti-slip rubber pads 7, increases the clamping points with the pipe, preventing pipe rotation or axial movement during cutting and ensuring a smooth cut without surface scratches.

[0022] Specifically, the cutting table 1 is equipped with a drive assembly 6 for driving two sets of movable clamping plates 5 to move synchronously. The drive assembly 6 includes a cavity 61 inside the cutting table 1, in which a threaded rod 62 is rotatably installed. A forward and reverse motor 63 is installed on the cutting table 1 to drive the threaded rod 62 to rotate. A slider 64 is threadedly connected to the threaded rod 62. A guide rod 65 passing through the slider 64 is also provided inside the cavity 61. Several strip-shaped openings 66 are opened on the upper surface of the cutting table 1. The two sets of movable clamping plates 5 pass through the corresponding strip-shaped openings 66 and are fixedly connected to the slider 64. In actual use, the forward and reverse motor 63 drives the threaded rod 62 to rotate, causing the slider 64 in the cavity 61 to drive the two sets of movable clamping plates 5 to move back and forth in the strip-shaped openings 66, respectively cooperating with the two fixed clamping plates 4 to clamp the pipe.

[0023] Working Principle: During operation, the operator places the pipe to be cut onto the fixed clamping plate 4 at station B. The drive assembly 6 is activated, causing the movable clamping plate 5 to clamp the pipe. The lead screw module 31 drives the cutting blade 34 to move along the Y-axis to station A. The drive motor 33 cuts the clamped pipe at a speed of 2800 r / min. Simultaneously, station B completes the loading process. After cutting at station A, the cutting device 3 automatically moves to station B for further cutting. At this point, station A releases the movable clamping plate 5, allowing the operator to unload the old pipe and place a new one.
