AI Technical Summary
The clamping surface of the existing hydraulic traction mechanism is a flat plate structure, which results in low friction between the clamping surface and the profile, making it prone to slippage.
A pad with anti-slip grooves is added to the pressure plate. A connecting bolt is screwed into the anti-slip groove. The connecting bolt passes through the pad and screws into the pressure plate. The effective depth of the anti-slip groove is adjusted by the screwing depth to increase the friction.
By adjusting the depth of the anti-slip grooves, the friction between the large material and the pressure plate is increased, preventing slippage.

Abstract
Description
Technical Field
[0001] This application relates to the field of sheet metal processing technology, and in particular to a profile traction structure. Background Technology
[0002] The traction mechanism is a crucial module in the pultrusion molding system for profiles. Existing hydraulic traction mechanisms mainly consist of a frame, clamping cylinders, and pressure plates. The clamping cylinders are mounted on the frame and push the pressure plate downwards towards the base plate to clamp the profile between the pressure plate and the base plate. Since the clamping surfaces of the pressure plate and the base plate are typically flat, the friction between them and the profile is low, making slippage prone to occur. To address this, the inventors have proposed a profile traction structure. Utility Model Content

The clamping surface of the pad is provided with an anti-slip groove, and a connecting bolt is screwed into the anti-slip groove. The connecting bolt passes through the pad and is screwed into the pressure plate. The connecting bolt is provided with a filler strip located inside the anti-slip groove.
[0006] By adopting the technical solution of this application, a pad with anti-slip grooves is added to the pressure plate, and the effective depth of the anti-slip grooves changes with the screwing depth of the connecting bolts, which can increase the friction between the plate and the profile and prevent slippage.

[0008] In some implementations, adjacent anti-slip grooves are arranged symmetrically.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.
[0026] Please see Figure 1 In related technologies, the traction mechanism is an important module of the profile pultrusion system. Existing hydraulic traction mechanisms mainly include a frame 10, a clamping cylinder 20, and a pressure plate 30. The clamping cylinder 20 is mounted on the frame 10 and pushes the pressure plate 30 downwards towards the base plate to clamp the profile between the pressure plate and the base plate. Because the clamping surfaces of the pressure plate and the base plate are usually flat, the friction between them and the profile is relatively low, making slippage prone to occur.
[0027] This embodiment provides a profile traction structure with an adjustable groove on its clamping surface, which can increase the friction between the clamping surface and the profile and prevent slippage.
[0028] Please see Figures 2-3In this embodiment, a profile traction structure includes a frame 10, a clamping cylinder 20 and a pressure plate 30, and also includes a pad 40. The clamping surface of the pad 40 is provided with an anti-slip groove 41. A connecting bolt 43 is screwed into the anti-slip groove 41. The connecting bolt 43 passes through the pad 40 and is screwed into the pressure plate 30. The connecting bolt 43 is provided with a filler strip 42 located inside the anti-slip groove 41.
[0029] By adopting the technical solution of this embodiment, a pad 40 with an anti-slip groove 41 is added to the pressure plate 30, and the effective depth of the anti-slip groove 41 changes with the screwing depth of the connecting bolt 43, which can increase the friction between the bolt and the profile and prevent slippage.
[0030] It should be noted that the pad 40 is made of rigid plastic and is constructed as a longitudinally elongated rectangular strip. Multiple anti-slip grooves 41 are arranged at intervals on the clamping surface of the pad 40, and the anti-slip grooves 41 are arranged at an angle relative to the direction of profile movement. Adjacent anti-slip grooves 41 are arranged symmetrically, that is, adjacent anti-slip grooves 41 are arranged in a figure-eight structure. The anti-slip groove 41 extends from one side wall of the pad 40 to the opposite side wall. The anti-slip groove 41 is constructed as a rectangle along its cross-section. A threaded hole is provided at the bottom of the anti-slip groove 41, which is used to form a threaded connection with the connecting bolt 43.
[0031] In addition, the filler strip 42 is constructed into a rectangular strip that matches the shape of the anti-slip groove 41, and the filler strip 42 is the same length as the anti-slip groove 41. The filler strip 42 and the anti-slip groove 41 are arranged in parallel. A smooth hole 421 is provided at the middle position along the length direction of the filler strip 42. The smooth hole 421 corresponds to the aforementioned threaded hole and is used to pass through the connecting bolt 43. The smooth hole 421 passes through the filler strip 42, and countersunk holes 422 are provided at both ends of the smooth hole 421. The connecting bolt 43 is rotatably inserted inside the smooth hole 421. A limiting plate 431 is screwed onto the connecting bolt 43. The limiting plate 431 and the bolt head of the connecting bolt 43 are located inside the countersunk holes 422 at both ends of the smooth hole 421, thereby connecting the connecting bolt 43 and the filler strip 42 into one unit and allowing relative rotation between the two.
[0032] It should also be noted that the connecting bolt 43 is arranged in the middle of the anti-slip groove 41. The connecting bolt 43 is arranged perpendicularly to the pad 40. The connecting bolt 43 and the threaded hole at the bottom of the anti-slip groove 41 form a threaded connection. After the connecting bolt 43 passes through the threaded hole, it forms a threaded connection with the pressure plate 30. The connecting bolt 43 connects the pad 40 and the pressure plate 30 into a whole structure.
[0033] It should be understood that since the filler strip 42 is fully engaged inside the anti-slip groove 41, the anti-slip groove 41 restricts the rotation of the filler strip 42, and relative rotation can occur between the filler strip 42 and the connecting bolt 43. Therefore, as the connecting bolt 43 is screwed in or out, the height of the filler strip 42 inside the anti-slip groove 41 will change, thereby changing the effective depth of the anti-slip groove 41.
[0034] In this embodiment, in order to further increase the friction between the material and the profile, a pad 40 with the same structure is also provided on the bottom plate opposite to the pressure plate 30.
[0035] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
