Description
Technical fields:
[0001] This utility model relates to the field of wedges in stamping dies, and more particularly to a large-stroke double-acting counter-punching wedge. Background technology:
[0002] A wedge mechanism is a mechanical mechanism that converts vertical motion into horizontal or tilting motion, and it is widely used in the stamping die industry. A traditional wedge mechanism generally consists of three main parts: a base assembly, a slide assembly, and a drive assembly. The mounting surface of the stamping tool is located in front of the slide, and it punches parts along the slide's forward direction.
[0003] However, for parts with negative angles on the blanking surface, that is, the angle between the blanking surface of the part and the forward direction of the slide is less than 90°, the part is upside down on the stamping die, making it impossible to remove the part normally after blanking. In this case, the traditional wedge is not applicable. Utility Model Content:

The rear guide slide unit is slidably engaged with the vertical guide plate.
[0010] As a preferred embodiment, the slider seat includes a sliding part, a front mounting part, and a drive connection part. The bottom of the sliding part is slidably disposed on a horizontal guide plate, the front mounting part is disposed at the front end of the sliding part, one end of the drive connection part is fixedly connected to the rear end of the sliding part, and the other end of the drive connection part extends obliquely upward and contacts the drive part to limit the movement direction of the drive seat.
[0011] Furthermore, the lower end of the sliding part is provided with a discharge pipe in the vertical direction.
[0012] Furthermore, both the sliding part and the driving part are right-angled trapezoidal structures, and they are arranged opposite each other. The driving block and slider are designed to be compact, which saves space.

[0034] This utility model relates to the field of wedges in stamping dies, and more particularly to a long-stroke, double-acting, counter-acting wedge. This utility model achieves a double-acting structure in the horizontal direction by adding a retraction component at the lower end of a traditional wedge slider assembly. The retraction component moves in the opposite direction to the slider in the horizontal direction, allowing the wedge to retract into place after work, thus increasing the retraction stroke and ensuring that negative angle parts can be properly removed after stamping. Simultaneously, the overall structure adopts a V-shaped design, uses copper-to-steel friction, employs a nitrogen cylinder for the retraction force, features a long working stroke for the flat wedge, and incorporates a sleeve design for the slider assembly, enabling reverse punching and material discharge. This also ensures the stability of the wedge, high load-bearing capacity, and punching and shaping capabilities even for long negative angle parts. This utility model solves the technical problems associated with punching negative angle parts.
[0035] This utility model provides a long-stroke double-acting counter-punching wedge, including a drive seat 1, a slider seat 2, a return seat 3, and a base 4.

A gap is reserved between the front end of the return seat 3 and the front end of the slider seat 2 for installing stamping parts.
[0036] The drive seat 1 includes a drive part 101, an upper mounting part 102, and a rear guide slide part 103. The bottom of the drive part 101 is slidably connected to the slider seat 2. The upper mounting part 102 is disposed at the upper end of the drive part 101.

One end of the drive connection part 203 is fixedly connected to the rear end of the sliding part 201, and the other end of the drive connection part 203 extends obliquely upward and contacts the drive part 101 to limit the movement direction of the drive seat 1. The front mounting part 202 is used to mount the stamping tool. The lower end of the sliding part 201 is provided with a discharge pipe 204 in the vertical direction. Both the sliding part 201 and the drive part 101 are right-angled trapezoidal structures and are arranged opposite each other.
[0038] The retraction seat 3 includes a front retraction part 301, a rear retraction part 302, and a bottom connecting part 303. Both the front retraction part 301 and the rear retraction part 302 extend upwards. The bottom connecting part 303 is disposed between the front retraction part 301 and the rear retraction part 302. The bottom of the slider seat 2 is slidably mounted on the bottom connecting part 303. The front end of the rear retraction part 302 is provided with a vertical guide plate 304 that cooperates with the drive seat 1. The upper end of the bottom connecting part 303 is provided with a horizontal guide plate 305 that cooperates with the slider seat 2.
[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0040] Figure 1 This is a schematic diagram of the working state of the counter-thrust wedge of this utility model. The punch 6 is installed on the front mounting part 202 at the front end of the slider seat 2. The negative angle part 5 is set in the gap between the slider seat 2 and the return seat 3. The negative angle part 5 is clamped towards the return seat 3 and upside down on the top of the return seat 3.
[0041] like Figure 2 The diagram shows a three-dimensional structural representation of the wedge mechanism of this invention, which consists of four main parts: a drive assembly 1, a slider assembly 2, a retraction assembly 3, and a base assembly 4. The mounting surface of this invention is located in front of the wedge's driving direction. The slider assembly 2 punches parts from the front of the drive assembly 1 along the guide surface of the drive assembly 1. The retraction assembly 3 moves from the rear of the drive assembly 1 along the guide surface of the drive assembly 1, punching parts in the opposite direction to the movement of the slider assembly 2. The base assembly 4 is fixed, providing retraction power and a limiting direction for the retraction assembly 3.
[0042] The motion process of the wedge mechanism of this utility model is as follows: Figure 3 , Figure 4 , Figure 5 As shown, when the drive component 1 moves horizontally downwards, and the drive component 1 initially contacts the inclined surface of the slider component 2, as follows... Figure 3 As shown, drive assembly 1 causes slider assembly 2 to move horizontally to the right by squeezing, while simultaneously compressing the nitrogen cylinder of retraction assembly 3, putting it into a stressed state. When drive assembly 1 continues to move horizontally downwards to reach... Figure 4 At the indicated position, slider assembly 2 continues to move horizontally to the right, while drive assembly 1 contacts the left side of retraction assembly 3, causing retraction assembly 3 to move horizontally to the left through compression. Simultaneously, the nitrogen cylinder of base assembly 4 is compressed, placing it under force. Drive assembly 1 continues to move horizontally downwards to reach the indicated position. Figure 5 The movement reaches its endpoint at the position shown, completing the punching operation. The rear drive assembly 1 moves horizontally upwards to the position shown. Figure 4 At the indicated position, the nitrogen cylinder in the base assembly 4 provides force to move the retraction assembly 3 horizontally to the right back to its initial position. The rear drive assembly 1 continues to move horizontally upward to reach the indicated position. Figure 3At the indicated position, the nitrogen cylinder in the retraction assembly 3 simultaneously provides force, causing the slider assembly 2 to move horizontally to the left back to its initial position, completing one stroke. The drive assembly 1 moves back and forth up and down, pressing the slider assembly 2, and the retraction assembly 3 moves left and right, forming a continuous punching process for the part. The retraction assembly 3 has a retraction function, thus solving the problem of punching parts with negative angles. When the retraction assembly 3 retracts to its initial position, it avoids the angled position of the negative angle part, allowing the negative angle part to be properly removed after punching, thus solving the technical problem of punching parts with negative angle punching surfaces.

The nitrogen cylinder is mounted on the lower right side of the inner cavity of the retraction seat 3, providing force for the retraction movement of the slider seat 2. The nitrogen cylinder mounting plate is installed on the lower right side of the return seat 3, serving to fix and limit the nitrogen cylinder. The nitrogen cylinder top block is installed on the lower left side of the return seat 3, providing a force-bearing surface for the nitrogen cylinder's force. The entire return assembly moves back and forth horizontally, allowing it to avoid the angled position of the negative angle part after the punching work is completed, thus enabling the negative angle part to be properly removed after punching.
[0047] The base assembly includes a base 4, a steel pressure plate, a copper guide plate, a spring fixing seat, a nitrogen cylinder, a positioning key, and a convex steel guide plate. The steel pressure plate is mounted on the upper surface of the base 4, serving to limit the retraction component 3 and provide guidance. The copper guide plate is mounted on the lower surface of the inner cavity of the base 4, reducing the coefficient of friction and guiding the slide. The spring fixing seat is mounted on the left side of the base 4, fixing and limiting the nitrogen cylinder. The nitrogen cylinder is mounted on the right side of the spring fixing seat and is associated with the base 4, providing force for the retraction movement of the retraction seat 3. The positioning key is mounted on the lower surface of the base 4, providing a fixing and limiting function. The convex steel guide plate is mounted on the lower right side of the inner cavity of the base 4, providing directional guidance and sliding. The base assembly, as a whole, provides a fixed state, motion space, retraction power, and limiting direction for the retraction component, ensuring its normal retraction operation and smooth operation of the entire wedge mechanism.
