Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die with an automatic unloading function. Background Technology
[0002] A stamping die is a special type of equipment used in cold stamping processes to process strip material into parts or semi-finished products. The stamping process involves applying pressure to the strip material at room temperature using a die mounted on a press, causing it to separate or undergo plastic deformation to obtain the desired part.
[0003] Currently, in actual production, after stamping, some products have a special structure where the punch fits too tightly to the product. This necessitates manual removal of the stamped product from the punch during the unloading process. This unloading method is not only time-consuming and labor-intensive but also poses a risk of injury to operators, severely impacting work efficiency.
[0004] In view of this, the present invention provides a stamping die with an automatic unloading function to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to overcome the problems of time-consuming, labor-intensive, and inefficient manual unloading in the existing stamping process, and to provide a stamping die with automatic unloading function. By setting an unloading component through the upper die, the product attached to the upper die is detached, thereby improving production efficiency and ease of operation.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A stamping die with automatic stripping function includes a limiting member, an upper die, and a lower die adapted to the upper die. The limiting member is fixedly installed on a stamping press. The upper die is installed on a die shank and located between the limiting member and the lower die. A stripping component is provided inside the upper die. The upper die includes an outer sleeve with a cavity extending vertically through it. An upper gasket is provided at the upper part of the cavity, and a middle sleeve is provided at the lower part. A fine blanking component is provided inside the middle sleeve. The upper end of the fine blanking component abuts against the upper gasket, and the lower end protrudes from the middle sleeve. The stripping component passes through the upper gasket and the middle sleeve sequentially from top to bottom and is located around the fine blanking component.
[0008] Furthermore, the unloading assembly includes a force transmission component and an unloading component. The force transmission component passes through the upper gasket, and the unloading component passes through the middle sleeve. The lower end of the force transmission component contacts the upper end of the unloading component.
[0009] Furthermore, the unloading component includes a pad block, the upper end of which contacts the force transmission component, and the lower end of which is fixedly connected to the pusher component that passes through the middle sleeve. An elastic component is provided between the pad block and the middle sleeve, with the upper end of the elastic component contacting the pad block and the lower end contacting the middle sleeve.
[0010] Furthermore, the lower end of the pusher is flush with the lower end of the middle sleeve.
[0011] Furthermore, the central axes of the force transmission component and the pusher component coincide.
[0012] Furthermore, at least one set of the unloading assembly is provided.
[0013] Furthermore, the outer sleeve and the upper pad, as well as the outer sleeve and the middle sleeve, are detachable connections.
[0014] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:
[0015] This utility model provides a stamping die with an automatic stripping function. A stripping component is installed through the upper die, comprising a force transmission component and a stripping component. The force transmission component passes through an upper gasket, and the stripping component passes through a middle sleeve. The stripping component is equipped with an elastic element. After stamping, the stripping component moves upward with the upper die until the force transmission component contacts a limiting component fixedly mounted on the press. The stripping component then continues to move upward, and the limiting component applies a downward force to the stripping component through the force transmission component. The stripping component moves downward, pushing the product away from the upper die. During the next stamping cycle, the stripping component moves downward with the upper die, the force transmission component moves away from the limiting component, and the stripping component resets under the action of the elastic element, without affecting the next stamping cycle. The entire process effectively improves stamping production efficiency while enhancing the ease of operation and safety of the die. Attached Figure Description

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses consistent with some aspects of this invention as detailed in the appended claims.
[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] Example
[0023] See Figure 1 A stamping die with automatic stripping function includes a limiting member, an upper die, and a lower die 7 adapted to the upper die. The limiting member is fixedly installed on a stamping press. The upper die is installed on a die shank and located between the limiting member and the lower die 7. A stripping component is provided inside the upper die. The upper die includes an outer sleeve 3. A cavity is formed through the outer sleeve 3 from top to bottom. An upper gasket 4 is provided at the upper part of the cavity, and a middle sleeve 5 is provided at the lower part. A fine blanking component 6 is provided inside the middle sleeve 5. The upper end of the fine blanking component 6 abuts against the upper gasket 4, and the lower end protrudes from the middle sleeve 5. The stripping component passes through the upper gasket 4 and the middle sleeve 5 from top to bottom and is located around the fine blanking component 6. After the stamping process is completed, the product is attached to the bottom of the fine blanking assembly 6. The upper die and the stripper assembly move upward with the slider installed on the stamping press. When they move to a certain extent, the stripper assembly contacts the limiting member. The stripper assembly continues to move upward, and the limiting member applies a downward force to the stripper assembly. The stripper assembly moves downward and pushes the product away from the fine blanking assembly 6.
[0024] The outer sleeve 3 is detachably connected to the upper shim 4 and to the middle sleeve 5 to prevent the upper shim 4 and the middle sleeve 5 from shifting during the stamping process. In this embodiment, the outer sleeve 3 is connected to the upper shim 4 and the middle sleeve 5 respectively by bolts provided on its side. The fine blanking assembly 6 includes a fine blanking pad and a fine blanking head. The fine blanking head is disposed inside the middle sleeve 5. The upper end of the fine blanking head abuts against the fine blanking pad, and the lower end protrudes from the middle sleeve 5. The fine blanking pad is located between the upper shim 4 and the fine blanking head. The stripping assembly is located on the periphery of the fine blanking assembly 6, and a certain distance is provided between the stripping assembly and the fine blanking assembly 6 to avoid mutual interference between the two.
[0025] In this embodiment, the unloading assembly includes a force transmission component 1 and an unloading component 2. The force transmission component 1 penetrates the upper gasket 4, and the unloading component 2 penetrates the middle sleeve 5. The lower end of the force transmission component 1 contacts the upper end of the unloading component 2. After the unloading assembly moves upward to a certain position, the force transmission component 1 contacts the limiting component, and the unloading assembly continues to move upward. The limiting component applies a downward force to the force transmission component 1, and the force transmission component 1 pushes the unloading component 2 downward. There are multiple ways in which the force transmission component 1 contacts the limiting component. The force transmission component 1 protrudes outside the upper gasket 4, and the limiting component is set as a flat plate structure. The upper end of the force transmission component 1 is flush with or recessed in the upper gasket 4. The limiting component has a protrusion adapted to the force transmission component 1 at a position opposite to the force transmission component 1, which is used to apply force to the force transmission component 1.
[0026] In this embodiment, the unloading component 2 includes a pad 21. The upper end of the pad 21 contacts the force transmission component 1, and the lower end is fixedly connected to the pusher component 23 that passes through the middle sleeve 5. An elastic component 22 is provided between the pad 21 and the middle sleeve 5, with the upper end of the elastic component 22 contacting the pad 21 and the lower end contacting the middle sleeve 5. During the unloading process, the force transmission component 1 transfers the force to the pusher component 23 through the pad 21. As the pad 21 moves downward, the elastic component 22 is compressed, and the bottom end of the pusher component 23 protrudes from the middle sleeve 5, pushing the product attached to the fine stamping assembly 6 away, thus completing the unloading. When stamping the next product, the force transmission component 1 separates from the limiting component, the force transmission component 1 is no longer under force, the elastic component 22 resets, and applies an upward force to the pad 21 through contraction, thus completing the reset of the pusher component 23 and the force transmission component 1. In this embodiment, the force transmission member 1 is used to transmit an axial downward force to the pusher member 23. It is configured as a rod-shaped structure. The force transmission member 1 can slide up and down in the upper pad 4. The elastic member 22 is used to support or reset the pad 21 and the force transmission member 1. The elastic member 22 is a spring. The pusher member 23 slides up and down in the middle sleeve 5. The length of its downward sliding that exposes the middle sleeve 5 can contact the product attached to the fine blanking assembly 6 and push it away from the fine blanking assembly 6.
[0027] In this embodiment, the lower end of the pusher 23 is flush with the lower end of the middle sleeve 5, and the length of the pusher 23 is greater than the axial height of the middle sleeve 5. When stamping products, the pusher 23 will not affect the product quality and can achieve the purpose of pushing the product.
[0028] In this embodiment, the central axes of the force transmission component 1 and the pusher component 23 coincide, so that the axial force of the force transmission component 1 is uniformly transmitted to the pusher component 23.
[0029] In this embodiment, two sets of stripping components are provided. The pusher 23 is located above the material strip placement position of the lower mold 7, ensuring that when the pusher 23 is exposed in the middle sleeve 5, it can contact the product and push the product.
[0030] In the above embodiments, the number of unloading components, the size of each component, and the connection method between each component are designed and determined according to actual needs.
[0031] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
[0032] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
