Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a stamping press base plate. Background Technology

[0002] A clutch disc is a mechanical component that primarily functions through friction and is an essential part of a punch press. During friction operation, the friction material must withstand high temperatures, significant pressure, and shear forces. Therefore, the friction material must possess sufficient mechanical strength to prevent damage and breakage during processing or use. A clutch disc, also known as a circular base plate, consists of an annular plate and several friction discs detachably connected to it. The annular plate is typically connected to the punch press, and the friction discs rub against the press to generate significant friction for braking. However, currently, the friction discs are often connected to the annular plate via threaded holes. Due to the small diameter and large number of these threaded holes, aligning the friction discs with the annular plate's threaded holes is quite cumbersome.

[0003] For example, in patent number CN221374287U, "A novel punch press circular base plate", the T-slots on the annular plate and the T-blocks on the sector plate are connected to improve convenience. However, after the T-slots are opened on the annular plate, its strength to withstand pressure and shear force is greatly reduced, making it extremely easy to be damaged and unable to be used normally.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a punch press substrate to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a punch press base plate, comprising an annular plate, multiple sector plates and multiple friction plates, wherein the multiple sector plates are equally spaced and arranged in a ring on the annular plate, and both the annular plate and the sector plates are provided with through holes of the same size, wherein the annular plate is provided with multiple sets of limiting protrusions, the number of the limiting protrusions being the same as the number of sector plates, and the sector plates being arranged between a set of limiting protrusions.

[0009] Preferably, a sliding groove is provided on one side of the set of limiting protrusions, and sliding strips are provided on both sides of the fan-shaped plate, with the sliding strips and sliding grooves being slidably connected.

[0010] Preferably, the extension lines on both sides of the limiting protrusion pass through the center of the annular plate.

[0011] Preferably, reinforcing ribs are provided between the groups of limiting protrusions, and the reinforcing ribs are multiple groups of arc-shaped strips that coincide with the center of the annular plate.

[0012] Preferably, when the slider (21) moves along the sliding groove toward the center of the annular plate until it can no longer move, the through holes on the annular plate and the sector plate coincide.

[0013] (III) Beneficial Effects

[0014] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The present utility model provides a punch press base plate in which a fan-shaped plate is inserted between the limiting protrusions, and at the same time the slide bar enters the sliding groove to complete the limiting of the fan-shaped plate. After sliding in to the point where it can no longer move, the through holes for bolt fixing on the annular plate and the fan-shaped plate automatically coincide, and no grooves or slots are opened on the fan-shaped plate and the annular plate, ensuring that its working strength is not affected.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This utility model embodiment provides a punching press base plate, such as Figure 1-2 As shown, the device includes an annular plate 1, multiple sector plates 2, and multiple friction plates 3. The sector plates 2 are arranged in a ring at equal intervals on the annular plate 1. Both the annular plate 1 and the sector plates 2 have through holes 4 of the same size. The annular plate 1 has multiple sets of limiting protrusions 5, the number of which is the same as the number of sector plates 2. The sector plates 2 are positioned between sets of limiting protrusions 5. The sector plates 2 are inserted along the limiting protrusions 5 into the spaces between the sets of limiting protrusions 5, thus achieving positioning and fixation.

[0020] Reference Appendix Figure 1-2 A sliding groove 51 is provided on one side of a set of limiting protrusions 5, and sliding strips 21 are provided on both sides of the sector plate 2. The sliding strips 21 and the sliding grooves 51 are slidably connected. The extension lines of the two sides of the limiting protrusions 5 pass through the center of the annular plate 1. Therefore, when the sector plate 2 is inserted along the limiting protrusions 5 on the outside of the annular plate 1, as the limiting protrusions 5 narrow, when the sector plate 2 moves to the point where it can no longer move, the through holes 4 on the annular plate 1 and the sector plate 2 just coincide.

[0021] Reference Appendix Figure 1-2 The limiting protrusions 5 are provided with reinforcing ribs 6 between the groups. The reinforcing ribs 6 are multiple groups of arc-shaped strips and coincide with the center of the annular plate 1. The setting of the arc-shaped reinforcing ribs 6 further improves the ability of the annular plate to withstand pressure and shear force.

[0022] This utility model discloses a punch press base plate, in which a fan-shaped plate is inserted between limiting protrusions, and a slider is simultaneously inserted into a sliding groove to limit the fan-shaped plate. After sliding in until it can no longer move, the through holes for bolt fixing on the annular plate and the fan-shaped plate automatically coincide. Furthermore, no grooves or slots are opened on the fan-shaped plate and the annular plate, ensuring that its working strength is not affected.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
