Description

Technical Field

[0001] This utility model relates to the field of plastic processing machinery, and in particular to a traction pipe auxiliary cutting device for the production of PE steel wire mesh reinforced pipe. Background Technology

[0002] Polyethylene steel wire mesh reinforced pipe is a new type of composite pipe. It uses a mesh-like skeleton formed by winding high-strength steel wires on both sides as reinforcement, with high-density polyethylene as the matrix for both inner and outer layers. The pipes are bonded together with hot melt adhesive and then extruded. This pipe combines the rigidity of metal with the corrosion resistance and flexibility of polyethylene, exhibiting high pressure resistance and wide application in water supply, petroleum, and chemical industries.

[0003] On the aforementioned continuous production line for pipes, the extruded and cooled pipes are clamped and pulled out at a uniform speed by traction equipment. Once the predetermined length is reached, a cutting operation is required. Currently, operators use handheld electric cutting tools to intermittently cut the continuously moving traction pipe. Specifically, the operator does not completely cut the pipe, but rather cuts most of the pipe's circumference at predetermined locations, leaving a small portion connected. As the pipe continues to move under traction, the remaining uncut portion naturally bends and contracts towards the pipe's central axis under stress, eventually breaking and forming an inwardly tapered fracture. This tapered head is then directly used for clamping and pulling by subsequent traction equipment.

[0004] However, during cutting, the severed portion, still under the traction force from the front and freed from the constraint from the rear, will rapidly bend inwards to form a cone shape. This sudden deformation causes vibration and displacement of the entire pipeline, severely interfering with the operator's positioning and operation of subsequent cutting points, making subsequent cutting operations more difficult, further deteriorating the cut quality, and seriously affecting production efficiency and product yield. Utility Model Content

[0005] To overcome the drawback of stress bending during pipe cutting, this utility model provides a traction pipe auxiliary cutting device for the production of PE steel wire mesh reinforced pipes, aiming to solve the above-mentioned shortcomings.

[0006] A traction pipe auxiliary cutting device for the production of PE steel wire mesh reinforced pipe includes a base and a mounting plate. Connecting blocks are connected to both the left and right ends of the middle of the base. A fixed seat is connected to the bottom of the mounting plate. A clamping ring for sleeved pipe is connected to the rear side of the mounting plate. The clamping ring is arranged in two layers. The fixed seat contacts the top surface of the connecting blocks. The mounting plate is vertically arranged above the base. The fixed seat is provided with a lifting component for adjusting the height of the mounting plate.

[0007] More preferably, the lifting assembly includes a motor, the motor is mounted on the top of the fixed base, a lead screw is threadedly connected to one of the connecting blocks, a guide rod is slidably connected to the other connecting block, the top end of the lead screw is connected to the output shaft of the motor, the top end of the guide rod is fixedly connected to the bottom surface of the fixed base, and a controller is mounted on the front side of the mounting plate, the controller being wired to the motor.

[0008] More preferably, the front side of the top of the base is covered with an anti-slip pad.

[0009] More preferably, a collection box is provided on the rear side of the top surface of the base.

[0010] More preferably, the base is equipped with several casters.

[0011] More preferably, the inner side of the double-layer sandwich of the clamping ring is connected with a rubber pad.

[0012] Compared with the prior art, the present invention has the following advantages: 1. By combining the clamping ring and the rubber pad, the end of the pipe is evenly clamped in the elastic interlayer, forming a stable fixed support, thereby achieving effective constraint on the pipe during the cutting process and preventing the pipe from bending and deforming due to stress release.

[0013] 2. Through the precise cooperation of the motor-driven lead screw and guide rod, the mounting plate can be raised and lowered smoothly, achieving accurate alignment between the cutting height and the center line of the pipe, ensuring that the cut end face is straight and vertical, and meeting the requirements of subsequent docking processes.

[0014] 3. The combination of anti-slip foot pads and casters enables operators to operate the equipment safely and stably and quickly position it, forming a flexible and reliable fixed working mode, improving work safety and efficiency. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this utility model are based solely on the accompanying drawings of this utility model and are not intended to specifically limit this utility model.

[0020] Example: A traction pipe auxiliary cutting device for the production of PE steel wire mesh reinforced pipe, such as... Figures 1-3 As shown, the device includes a base 1, a mounting plate 2, a clamping ring 3, a fixing seat 4, a connecting block 6, and a lifting assembly. The base 1 has connecting blocks 6 connected to both the left and right ends in the middle. The mounting plate 2 has a fixing seat 4 connected to the bottom. The mounting plate 2 has a clamping ring 3 connected to the rear side for mounting the pipe. The clamping ring 3 is double-layered and has baffles with equal spacing on its ring body to guide the cutting position. The clamping ring 3 adopts a split adjustable structure and can be finely adjusted according to the pipe diameter. In the initial state, the bottom surface of the fixing seat 4 is in contact with the top surface of the connecting block 6, and the mounting plate 2 is vertically set above the base 1. The fixing seat 4 is equipped with a lifting assembly for adjusting the height of the mounting plate 2.

[0021] like Figure 1 and Figure 3 As shown, the lifting assembly includes a motor 5, a controller 501, a lead screw 7, and a guide rod 8. The motor 5 is mounted on the top of the fixed base 4. The lead screw 7 is internally threaded onto one connecting block 6, and the guide rod 8 is slidably connected to another connecting block 6. The top of the lead screw 7 is connected to the output shaft of the motor 5. The motor 5 is a low-speed, high-torque model that runs smoothly. The top of the guide rod 8 is fixedly connected to the bottom surface of the fixed base 4. The lead screw 7 adopts a trapezoidal thread design, and the surface of the guide rod 8 is hardened. The controller 501 is mounted on the front side of the mounting plate 2, and the controller 501 is wired to the motor 5.

[0022] like Figure 1 As shown, it also includes anti-slip pads 9. Anti-slip pads 9 are laid on the front side of the top of the base 1. The surface of the anti-slip pads 9 has horizontal anti-slip textures of appropriate depth and is made of rubber material with a high coefficient of friction.

[0023] like Figure 1 As shown, it also includes a collection box 10. The collection box 10 is provided on the rear side of the top surface of the base 1. The collection box 10 adopts a detachable design and has a smooth inner surface.

[0024] like Figure 1As shown, it also includes casters 11. Several casters 11 are installed at the bottom of the base 1. The casters 11 are omnidirectional casters with a foot pedal brake and the wheel surface is made of wear-resistant rubber.

[0025] like Figure 2 As shown, it also includes a rubber pad 12. The inner side of the double-layer sandwich of the clamping ring 3 is connected to the rubber pad 12. The rubber pad 12 is made of wear-resistant polyurethane material and has appropriate elasticity and coefficient of friction.

[0026] In the continuous production process of PE steel wire mesh reinforced pipe, after the pipe is pulled to a predetermined length, it is cut first. Then, the operator moves this auxiliary cutting device to the front end of the pipe section to be pulled. The operator pushes the base 1, causing the movable wheels 11 installed at its bottom to rotate, thereby moving the entire device so that the clamping ring 3 is aligned with the predetermined cutting position on the pipe. The operator stands on an area covered with anti-slip pads 9 and operates the motor 5 through the controller 501. After the motor 5 starts, it drives the lead screw 7 to rotate. Since the lead screw 7 and the connecting block 6 on one side form a threaded pair, the rotational motion is converted into linear motion, pushing the fixed seat 4 to rise vertically. At the same time, the guide rod 8 on the other side slides within the corresponding connecting block 6, providing guidance and balance, ensuring the smooth lifting and lowering of the mounting plate 2. Through this adjustment process, the center of the clamping ring 3 installed on the mounting plate 2 can be precisely aligned with the center of the pipe, adapting to production line equipment of different heights.

[0027] After alignment, the operator pushes the base 1 again, inserting the end of the pipe into the double-layer structure of the clamping ring 3. Then, the moving wheel 11 is locked to fix the position of the base 1 and prevent the equipment from moving. When the pipe is inserted, its outer wall contacts the rubber pad 12 on the inner side of the clamping ring 3. The rubber pad 12 undergoes elastic deformation, which protects the pipe surface and enhances the stability of the clamping, preventing the pipe from shaking or slipping during cutting.

[0028] During the cutting operation, the operator uses a cutting tool to cut along the pre-defined intervals marked on the clamping ring 3, according to the area defined by the baffles. The baffles clearly indicate the cutting position and sequence, allowing for both circumferential and axial cutting, making the operation flexible and orderly. Debris generated during the cutting process falls directly into the collection box 10 located behind the base 1 for easy collection and to maintain a clean working environment.

[0029] After all cutting is completed, the operator releases the locking of the moving wheels 11, pulls the base 1 away from the production line, removes the cut pipe section from the clamping ring 3, and cleans the debris from the collection box 10. The horizontal stripes on the anti-slip foot pads 9 always provide a stable foothold for the operator, ensuring safety. Finally, the controller 501 controls the motor 5 to reverse, causing the fixed base 4 to descend until it is in contact with the top surface of the connecting block 6, restoring the device to its initial state and preparing it for the next operation.
