Description

Technical Field

[0001] This utility model relates to the field of precision stamping die technology, specifically a precision stamping die for a highly symmetrical automotive clutch integrated spring plate. Background Technology

[0002] Precision stamping dies are dies used for high-precision stamping processes. They are mainly used for punching, bending, stretching, and forming of metal or non-metal sheets to mass-produce parts with high dimensional accuracy, good surface quality, and complex shapes.

[0003] For example, patent application number CN201721642205.5 describes a precision stamping die. This precision stamping die uses a one-step direct cutting to a two-step cutting process. While ensuring product quality meets requirements, it reduces unnecessary downtime and changeovers, improves the service life of die components, and reduces maintenance frequency, thereby achieving the goal of reducing parts costs. However, during use, demolding is required. In the demolding process, it is inevitable that the die will come into contact with the product, causing damage and affecting product quality, thus compromising quality assurance.

[0004] For example, patent application number CN202322839143.9 relates to the field of stamping die technology and discloses a precision workpiece stamping die. This utility model achieves the effect of automatic unloading of stamped workpieces, avoiding manual unloading by workers, saving time and labor costs, and improving the practicality of the overall device. However, during use, demolding is required. In the process of demolding, it is inevitable that the die will come into contact with the product, causing damage to the product and affecting its quality, thus failing to guarantee quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a precision stamping die for a highly symmetrical automotive clutch integrated spring plate. The rotation of gears allows the push rod to rotate 90 degrees, increasing the distance between the connecting rod and the vertical rod, enabling simultaneous movement of both. When the vertical rod moves, the moving support rod separates from the lower die, facilitating the subsequent downward movement of the lower die. As the connecting rod moves, the bracket comes into contact with the upper and lower dies. When the upper die moves downward, both the upper and lower dies move downward simultaneously, allowing the lower die to move downward along the support rod, exposing the material on the fixed plate and completing the demolding process. This avoids deformation caused by contact demolding, ensuring product quality and solving the problem of damage caused by contact with the product during demolding, which negatively impacts product quality.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a precision stamping die for a highly symmetrical automotive clutch integrated spring plate, comprising a base, a motion mechanism disposed above the base, a lower die disposed below the motion mechanism, an upper die disposed on the top of the lower die, and an electric push rod fixedly disposed on the top of the upper die.

A moving rod is provided at the end of the threaded rod away from the rotating rod. The moving rod is threadedly connected to the threaded rod. A gear is provided at the bottom of the moving rod. A round rod is fixedly provided at the end of the gear near the upper mold. Push rods are provided at the top and bottom of the round rod. A bracket is provided below the gear. A vertical rod is provided on the side of the bracket away from the lower mold.

[0008] Preferably, the moving rod is slidably connected to the upper mold, and the bottom of the moving rod is provided with a toothed rail, which meshes with a gear.

[0009] Preferably, the bottom inner wall of the lower mold is provided with a groove, and a fixing plate is provided inside the groove, the fixing plate being in contact with the lower mold.

[0010] Preferably, support rods are provided at the bottom of both ends of the fixing plate, the support rods are in contact with the lower mold, and the fixing plate is fixedly connected to the base through the support rods.

[0011] Preferably, both ends of the lower mold are provided with movable support rods, which are in contact with the lower mold.

[0012] Preferably, a sliding rod is provided on the side of the moving support rod near the base, one end of the sliding rod is fixedly connected to the moving support rod, and the other end of the sliding rod extends into the interior of the base.

[0013] Preferably, a connecting rod is fixedly provided on the top of the bracket, the connecting rod is slidably connected to the upper mold, and the cross-sectional shape of the moving rod is L-shaped.

[0014] Preferably, a guide rod is provided below the moving rod, the guide rod passes through the bracket and contacts the bracket, and connecting springs are provided inside the base, outside the guide rod and bottom of the lower mold.

[0015] Preferably, a mounting rod is provided on one side of the base, and the base is fixedly connected to the electric push rod through the mounting rod.

[0016] Beneficial effects

[0017] This invention provides a precision stamping die for a highly symmetrical automotive clutch integrated spring plate. Compared with the prior art, it has the following advantages:

[0018] 1. This high-symmetry automotive clutch integrated spring plate precision stamping die, through the rotation of gears, allows the push rod to rotate 90 degrees, increasing the distance between the connecting rod and the vertical rod. This allows the connecting rod and the vertical rod to move simultaneously. When the vertical rod moves, the moving support rod separates from the lower die, facilitating the subsequent downward movement of the lower die. When the connecting rod moves, the bracket comes into contact with the upper and lower dies. When the upper die moves downward, both the upper and lower dies move downward simultaneously, allowing the lower die to move downward along the support rod. This exposes the material on the fixed plate, completing the demolding process and avoiding deformation caused by contact demolding, thus ensuring product quality.

[0019] 2. This high-symmetry automotive clutch integrated spring plate precision stamping die, through the contact between the bracket and the vertical rod, will make the bracket be located directly above the gap between the vertical rod and the lower die. The downward movement of the bracket can enter between the vertical rod and the lower die, without affecting the mold closing operation of the upper and lower dies. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a precision stamping die for a highly symmetrical automotive clutch integrated spring plate, including a base 1, a motion mechanism 2 above the base 1, a lower die 3 below the motion mechanism 2, an upper die 4 on the top of the lower die 3, and an electric push rod 5 fixedly mounted on the top of the upper die 4.

[0028] The motion mechanism 2 includes a rotating rod 201, and threaded rods 202 are fixedly provided at both ends of the rotating rod 201. There are two threaded rods 202, and the threads on the surfaces of the two threaded rods 202 are arranged in opposite directions. A moving rod 203 is provided at the end of the threaded rod 202 away from the rotating rod 201. The moving rod 203 is threadedly connected to the threaded rod 202. A gear 204 is provided at the bottom of the moving rod 203. A round rod 205 is fixedly provided at the end of the gear 204 near the upper mold 4. Push rods 206 are provided at the top and bottom of the round rod 205. A bracket 207 is provided below the gear 204. A vertical rod 208 is provided on the side of the bracket 207 away from the lower mold 3.

[0029] A mounting rod 6 is provided on one side of the base 1. The base 1 is fixedly connected to the electric push rod 5 through the mounting rod 6. The moving rod 203 is slidably connected to the upper mold 4. A toothed rail is provided at the bottom of the moving rod 203, and the toothed rail meshes with the gear 204. The movement of the moving rod 203 can cause the toothed rail to move and mesh with the gear 204, causing the gear 204 to rotate.

[0030] Both ends of the lower mold 3 are provided with moving support rods 211. The moving support rods 211 are in contact with the lower mold 3. A sliding rod 212 is provided on the side of the moving support rod 211 near the base 1. One end of the sliding rod 212 is fixedly connected to the moving support rod 211, and the other end of the sliding rod 212 extends into the interior of the base 1. The movement of the sliding rod 212 can stretch the connecting spring inside the base 1.

[0031] A connecting rod 213 is fixedly installed on the top of the support 207. The connecting rod 213 is slidably connected to the upper mold 4. The cross-sectional shape of the moving rod 203 is L-shaped. A guide rod 214 is installed below the moving rod 203. The guide rod 214 passes through the support 207 and is in contact with the support 207. Connecting springs are installed inside the base 1, outside the guide rod 214, and bottom of the lower mold 3. When the connecting rod 213 moves, the support 207 fixedly connected to the connecting rod 213 moves simultaneously, allowing the support 207 to move between the upper mold 4 and the lower mold 3. Because the guide rod 214 passes through the support 207 and is in contact with the support 207, the support 207 can move along the guide rod 214, allowing the support 207 to move linearly and compressing the connecting spring at the guide rod 214, which facilitates subsequent operations.

[0032] Please see Figure 2 and 5 The lower mold 3 has a groove on its inner bottom wall, and a fixing plate 209 is installed inside the groove. The fixing plate 209 is in contact with the lower mold 3. Support rods 210 are installed at both ends of the fixing plate 209. The support rods 210 are in contact with the lower mold 3. The fixing plate 209 is fixedly connected to the base 1 through the support rods 210. The fixing plate 209 can support the product. When the lower mold 3 moves downward, it moves downward along the support rods 210, which can prevent the product on the fixing plate 209 from moving downward with the lower mold 3. This will expose the material on the fixing plate 209, completing the demolding work and avoiding deformation caused by contact demolding, thus ensuring the quality of the product.

[0033] During operation, the material is placed in the lower mold 3. Using the electric push rod 5, the upper mold 4 moves downwards, reducing the distance between it and the lower mold 3 until they come into contact, allowing the product to be formed. As the upper mold 4 moves downwards, the supports 207 on both sides also move downwards simultaneously, positioning themselves between the lower mold 3 and the vertical rod 208, without affecting the downward movement of the upper mold 4. After forming is complete, the upper mold 4 returns to its original position, and the rotating rod 201 rotates, causing the threaded rods 202 on both sides to rotate. The threads on surface 02 are arranged in opposite directions, and the threaded rod 202 is threadedly connected to the moving rod 203. Rotation of the threaded rod 202 causes the moving rod 203 to move, and simultaneously moves the toothed rail below the moving rod 203. During the movement of the toothed rail, since the toothed rail meshes with the gear 204, the rotation of the toothed rail causes the gear 204 to rotate, and the round rod 205, which is fixedly connected to the gear 204, rotates simultaneously, driving the rotation of the push rod 206, causing the push rod 206 to rotate 90 degrees. During this rotation, the push rod 206 can interact with the connecting rod 213 and the vertical... When rod 208 moves, and push rod 206 is in a horizontal state, the movement of connecting rod 213 and vertical rod 208 stops. When connecting rod 213 moves, the bracket 207, which is fixedly connected to connecting rod 213, moves simultaneously, allowing bracket 207 to move between upper mold 4 and lower mold 3. Because guide rod 214 passes through bracket 207 and bracket 207 is in contact with it, bracket 207 can move along guide rod 214, allowing bracket 207 to move linearly and compress the connecting spring at guide rod 214, facilitating subsequent operations. When vertical rod 208 moves... At the same time, the moving support rod 211, which is fixedly connected to the vertical rod 208, moves simultaneously, separating the moving support rod 211 from the lower mold 3, facilitating subsequent operations. After the moving support rod 211 and the bracket 207 have moved, the electric push rod 5 is used again to move the upper mold 4 and the bracket 207 downwards. This causes the upper mold 4 and the lower mold 3 to move downwards simultaneously, allowing the lower mold 3 to move downwards along the support rod 210, which exposes the material on the fixed plate 209, completing the demolding process. This avoids deformation caused by contact demolding and ensures product quality.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
