Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction machine technology, and in particular to a pipe fixing and traction device for pipe processing. Background Technology
[0002] In the pipe extrusion process, the traction system is a key piece of equipment to ensure pipe shaping and continuous production. The equipment used for traction is the traction machine, which pulls the extruded plastic pipe out of the die head and then sends the plastic pipe into the pipe cutting machine.
[0003] The three types of traction machines commonly used in the existing technology are rubber belt type, roller type and crawler type. The existing traction machines, rubber belt type and roller type have relatively small traction force and are suitable for traction of small diameter pipes, while crawler type has larger traction force and is suitable for traction of large diameter pipes. The roller type traction machine is suitable for large diameter solid wall pipes. The upper and lower opposing roller groups clamp and pull the pipe to move. During the traction process, the roller group is in hard contact with the pipe, which can easily damage or deform the pipe. It can easily crush soft pipes, and the surface is relatively smooth, so it cannot be used to pull corrugated pipes.
[0004] Therefore, this application provides a pipe fixing and traction device for pipe processing to meet the requirements. Utility Model Content
[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a pipe fixing and traction device for pipe processing.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A pipe fixing and traction device for pipe processing includes: a base, a cabinet, an adjusting handwheel, a column, a fixed seat, a lower traction roller, a movable seat, an upper traction roller, an adjusting screw, a clamping block, a first connecting seat, a second connecting seat, a telescopic spring, and a sealing sleeve. The cabinet is mounted on the upper end of the base. An adjusting handwheel is mounted on the front of the cabinet. Columns are vertically mounted on the left and right sides of the upper end of the cabinet. A fixed seat is mounted at the lower outer end of each column. Several lower traction rollers are mounted on the front of the fixed seat. A movable seat is mounted on the upper end of the column above the fixed seat. Several upper traction rollers are mounted on the front of the movable seat. An adjusting screw is mounted at the top center of the movable seat. A clamping block is nested between the outer ends of the lower and upper traction rollers. A second connecting seat is heat-fused and fixed inside the clamping block. A telescopic spring is installed inside the second connecting seat. The other end of the telescopic spring is glued to the first connecting seat. A sealing sleeve is installed at the side opening of the clamping block.
[0008] Preferably, the clamping block is cylindrical, and the shape of the clamping block matches that of the lower traction roller and the upper traction roller.
[0009] Preferably, the clamping block is hollow inside, and the contact surface of the clamping block is arc-shaped.
[0010] Preferably, the surface of the sealing sleeve is provided with a circular through hole, and the output shafts of the lower traction roller and the upper traction roller extend through the sealing sleeve into the interior of the clamping block.
[0011] Preferably, the second connecting seat is provided in four groups, with the eight groups of second connecting seats located on the left and right sides of the upper and lower ends of the clamping block, respectively.
[0012] Preferably, the second connecting seat and the telescopic spring are arranged vertically.
[0013] Preferably, the first connecting seat extends to the sides of the lower and upper traction rollers at both ends via a telescopic spring, and the first connecting seat is fixed to the lower and upper traction rollers by bolts.
[0014] Preferably, the cavity of the clamping block is spaced apart from the outer end faces of the lower traction roller and the upper traction roller.
[0015] Preferably, the clamping block is made of polyurethane elastomer, and the contact surface of the clamping block is covered with a foamed silicone pad.
[0016] Preferably, the surface of the clamping block is uniformly distributed with toothed grooves.
[0017] Compared with the prior art, this utility model has at least the following beneficial effects:
[0018] In the above scheme, a cylindrical clamping block with a matching shape is nested at the outer end of the lower traction roller and the upper traction roller. The clamping block is fixed to the lower traction roller and the upper traction roller by bolts installed at the first connecting seat. The clamping block can contact the pipe, and the internally supported telescopic spring can be compressed. As the lower traction roller and the upper traction roller rotate, the telescopic spring can be compressed and deformed, so that the clamping block always stays in contact with the surface of the pipe. Thus, when the pipe is pulled, the traction pressure can be adjusted in real time to avoid overpressure causing elliptical deformation of the pipe, thereby adapting to changes in pipe stiffness.
[0019] In the above solution, the clamping block is made of polyurethane elastomer, and the contact surface of the clamping block is covered with a foamed silicone pad. While ensuring friction, the material is relatively soft and can balance gripping force and protection during traction. The surface of the clamping block is evenly distributed with toothed grooves, which can match the corrugated pipe, increase the contact area of the corrugated pipe, and pull the corrugated pipe.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention discloses a pipe fixing and traction device for pipe processing, which includes, according to an embodiment, a base 1, a cabinet 2, an adjusting handwheel 3, a column 4, a fixed seat 5, a lower traction roller 6, a movable seat 7, an upper traction roller 8, an adjusting screw 9, a clamping block 10, a first connecting seat 11, a second connecting seat 12, a telescopic spring 13, and a sealing sleeve 14. The cabinet 2 is mounted on the upper end of the base 1. The adjusting handwheel 3 is mounted on the front of the cabinet 2. Columns 4 are vertically mounted on the left and right sides of the upper end of the cabinet 2. Fixed seats 5 are mounted on the lower outer ends of the columns 4. Several lower traction rollers 6 are installed on the front of the fixed seat 5. A movable seat 7 is installed on the upper end of the column 4 located on the fixed seat 5. Several upper traction rollers 8 are installed on the front of the movable seat 7. An adjusting screw 9 is installed in the middle of the top of the movable seat 7. A clamping block 10 is nested on the outer ends of the lower traction rollers 6 and the upper traction rollers 8. A second connecting seat 12 is fixed inside the clamping block 10 by heat fusion. A telescopic spring 13 is installed inside the second connecting seat 12. The other end of the telescopic spring 13 is glued to the first connecting seat 11. A sealing sleeve 14 is installed at the side opening of the clamping block 10.
[0031] In this embodiment, the clamping block 10 is cylindrical, and the shape of the clamping block 10 matches that of the lower traction roller 6 and the upper traction roller 8, making it convenient to be nested and installed on the outer ends of the lower traction roller 6 and the upper traction roller 8. The shape of the clamping block 10, which matches the shape, is suitable for traction operations.
[0032] In this embodiment, the clamping block 10 is hollow inside, and the contact surface of the clamping block 10 is arc-shaped, so that the clamping block 10 has space to move up and down, and fits with pipes of different diameters.

[0038] In this embodiment, the clamping block 10 is made of polyurethane elastomer, and the contact surface of the clamping block 10 is covered with a foamed silicone pad. While ensuring friction, the material is relatively soft and can balance gripping force and protection during traction.
[0039] In this embodiment, the surface of the clamping block 10 is uniformly distributed with toothed grooves, which can match the corrugated pipe and increase the contact area of the corrugated pipe.
