Description

Technical Field

[0001] This utility model relates to a traction device for pipe extrusion, belonging to the technical field of traction devices. Background Technology

[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipe materials, and the quality of the pipe material directly determines the quality of the pipe fittings. Pipes are widely used in construction projects, power plants, chemical plants, and other fields. They are essential materials for construction projects. Common types include water supply pipes, drainage pipes, gas pipes, heating pipes, electrical conduits, and rainwater pipes. Traction devices are used during the production of pipes.

[0003] Chinese Patent Publication No. CN 212194122 U discloses a traction device for a rubber and plastic pipe extruder, comprising a base, support frames, reinforcing rods, screws, rotating sleeves, support plates, and sliding columns. Several sets of support frames are symmetrically welded to the front and rear ends of the upper surface of the base. Reinforcing rods are welded between the opposing support frames. The upper end of each reinforcing rod has a through hole through which the screw passes. A mounting plate is vertically welded to the top of the screw, and the mounting plate is fixed to the bottom end of the support plate by bolts. The support plate includes a first support plate and a second support plate. A rotating sleeve is threadedly connected to the screw between the mounting plate and the through hole. Grooves are equally spaced on the first and second support plates, and sliding columns are placed within these grooves. This invention reduces friction between the sliding columns on the support plates and the rubber and plastic pipe, which helps maintain the shape of the pipe. The included angle between the two support plates allows for traction of rubber and plastic pipes of various diameters, making it widely applicable and highly practical.

[0004] The aforementioned device mainly relies on manual rotation of the rotating sleeve multiple times to adjust the inner spacing of the sliding column. This process is cumbersome and time-consuming, and each adjustment wastes a lot of labor costs, resulting in low overall ease of use of the equipment and making it inconvenient for operators to use.

[0005] To address this, a traction device for pipe extrusion is proposed. Utility Model Content

[0010] More preferably, a limiting groove is provided at the bottom of the inner cavity of the box, and the bottoms of the two screw blocks are slidably connected to the inner cavity of the limiting groove.

[0011] More preferably, each of the two box covers has a movable groove at its top, and the support frame passes through the inner cavity of the movable groove and extends to the top of the box cover.

[0012] More preferably, each of the two box covers has mounting bolts on its surface, and the bottom of each of the four mounting bolts is threaded to the inner surface of the box body.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model embodiment provides a traction device for pipe extrusion, including a housing 1. A housing cover 3 is provided on both the left and right sides of the top of the housing 1. An electric traction frame 4 is provided on the top of each of the two housing covers 3. An adjustment mechanism 2 is provided on the surface of the housing 1. The adjustment mechanism 2 includes a motor 201 and connecting rods 204. The motor 201 is fixedly installed on the front side of the housing 1. The four connecting rods 204 are located on the left and right sides of the inner cavity of the housing 1. Moving rods 205 are movably connected to the outer sides of each of the four connecting rods 204. Support frames 206 are fixedly installed on the top of each of the two moving rods 205. Two electric traction frames 4 are fixedly installed on the top of the support frames 206. The output end of 201 is fixedly connected to a bidirectional screw 202. Both the front and rear sides of the surface of the bidirectional screw 202 are threaded with screw blocks 203. The inner sides of the four connecting rods 204 are movably connected to the outer sides of the two screw blocks 203. The left and right sides of the bottom of the inner cavity of the housing 1 are provided with sliding grooves 207. The bottom of the two moving rods 205 are slidably connected to the inner cavity of the four sliding grooves 207. The bottom of the inner cavity of the housing 1 is provided with a limiting groove 208. The bottom of the two screw blocks 203 are slidably connected to the inner cavity of the limiting groove 208. The top of the two housing covers 3 is provided with a moving groove 209. The support frame 206 passes through the inner cavity of the moving groove 209 and extends to the top of the housing cover 3.

[0030] By setting the adjustment mechanism 2, the connecting rod 204 drives the moving rod 205 to move inward through the output of the motor 201, thereby causing the electric traction frame 4 to move inward synchronously. By adjusting the inner spacing of the electric traction frame 4, the electric traction frame 4 can pull pipes of different sizes. At the same time, this adjustment method is relatively convenient, reduces the waste of labor costs, and is convenient for operators to use. By setting the sliding groove 207, the movement of the moving rod 205 can be limited to prevent the moving rod 205 from deviating during movement, which would affect the adjustment of the spacing of the electric traction frame 4. By setting the limiting groove 208, the movement of the screw block 203 can be limited to prevent the screw block 203 from changing direction during movement, which would affect the adjustment effect of the spacing of the electric traction frame 4. By setting the moving groove 209, the movement of the support frame 206 can be limited to prevent the support frame 206 from deviating during movement, which would affect the adjustment effect of the spacing of the electric traction frame 4.

[0031] Example 2

[0032] like Figure 1-3 As shown, in one embodiment, mounting bolts 5 are provided on the surface of both box covers 3. The bottom of the four mounting bolts 5 is threaded to the inner surface of the box body 1. A box body 7 is fixedly installed in the inner cavity of the box body 1. Rollers 8 are movably connected in the inner cavity of the box body 7. Anchor bolts 6 are threaded to the outer side of the box body 1. The four anchor bolts 6 are threaded to the ground.

[0033] By setting the mounting bolts 5, the cover 3 can be disassembled, facilitating maintenance of the components inside the housing 1. The housing 7 and rollers 8 provide support and guidance for the bottom of the pipe, preventing it from falling off the inside of the electric traction frame 4 due to its weight during traction. The anchor bolts 6 stabilize the entire equipment, preventing accidental collisions from external factors that could cause the equipment to shake and affect the traction of the pipe.

[0034] When this utility model is in operation: First, according to the size of the pipe, the output of the motor 201 causes the bidirectional screw 202 to rotate. At this time, the screw block 203 moves outward along the thread on the surface of the bidirectional screw 202, causing the connecting rod 204 to swing and pull the moving rod 205 to move inward. The support frame 206 simultaneously drives the electric traction frame 4 to move inward. The inner side of the electric traction frame 4 is in contact with the surface of the pipe. Then, through the operation of the electric traction frame 4, the pipe is pulled backward, completing the traction work of the pipe.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
