Description

Technical Field

[0001] The utility model relates to the technical field of mold design, in particular to a planetary plate punching mold which is convenient for processing and taking out parts. Background Art

[0002] Planetary plate punching dies are used to create holes in planetary plates. Traditionally, these punching dies have been used, often with limitations such as low precision, low punching efficiency, and inaccurate positioning. With the continuous advancement of industrial technology, the quality and performance requirements for planetary plates are becoming increasingly stringent, prompting continuous improvement and innovation in planetary plate punching die technology. New planetary plate punching dies typically utilize advanced design and manufacturing techniques to improve punching accuracy and die life, such as optimizing die structure design and enhancing punching stability and consistency.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Utility Model Content

[0005] In response to the problems existing in the existing technology, the utility model provides a planetary plate punching die that is easy to process and remove parts. The system optimizes the cavity structure of the punching die, increases the jaws, reduces the manufacturing cost, and improves the production efficiency. It effectively solves the technical problems of slow production efficiency caused by the difficulty in processing traditional punching dies and the difficulty in clamping out forgings after punching.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A planetary plate punching die that is convenient for processing and removing parts comprises: a punching convex die, a lower die plate and a punching concave die mounted on the lower die plate. The punching concave die is surrounded by four through holes, which are semi-cylindrical notches and are open structures facing the outside of the punching concave die.

[0008] According to one embodiment of the present invention, the punching die is provided with a lower step. The lower step is a plate extending upward from the outer edge of the punching die's upper surface. The plate has the same curvature as the outer edge of the punching die. No lower step is provided at the aperture. A circular hole is provided in the center of the punching die, which is a through hole. The punching die is provided with a jaw, which is a curved platform provided on the inner curved surface of the aperture. The curved platform is lower than the horizontal level of the punching die's upper surface. A circular array of stepped countersunk holes is provided on the punching die's upper surface. The stepped countersunk holes are cylindrical notches provided in the punching die.

[0009] The planetary plate parts in vehicle gearboxes have a structural feature, namely, there are four slender claws around them and four evenly arranged steps on the bottom surface, so the punching die needs to make corresponding avoidance.

[0010] The four holes arranged around the punching die are used to avoid the four slender claws of the forging. The holes are open to the outside, which is convenient for mechanical processing and can simplify the processing steps; the lower step provided on the punching die is used to position the forging. During the downward punching process of the punching punch, if the positioning of the forging deviates, the stamping position of the forging will be wrong or the stamping accuracy will be too low, which will have a huge impact on the qualified rate of the product, cause waste of resources, increase manufacturing costs and seriously affect production efficiency. Therefore, the positioning effect of the lower step on the forging can improve the stamping accuracy of the forging; the circular hole located in the middle of the punching die can make the forging waste generated during the stamping process fall from the circular hole, and the waste can be cleaned up in time and independently to avoid the accumulation of waste generated by stamping affecting the forming of the forging, and the circular hole can also be used as an exhaust hole to remove the gas accumulated during the stamping process in real time to avoid damage to the stamping machine due to high air pressure, thereby improving the service life of the machine and the qualified rate of the forging products.

[0011] A 40mm long, 40mm wide, and 20mm deep jaw is provided on a hollow arc surface of the punching die to facilitate clamping of forgings and improve production efficiency. The original planetary plate parts were difficult to remove from the mold cavity after the punching operation. If tools were used to forcibly remove the forgings, the forgings would likely be damaged, seriously affecting production efficiency. The punching die is now equipped with jaws. After the punching operation is completed, personnel can use tools to easily remove the forgings from the jaws without damaging the forgings, greatly improving production efficiency. Four stepped countersunk holes are provided in a circular array on the upper surface of the punching die to avoid steps on the forgings. The first step cooperates with the lower template to achieve centering positioning. The center of the lower template is provided with a circular countersunk hole of equal size to the first step. The first step can be placed in the circular countersunk hole to achieve centering positioning and improve stamping accuracy.

[0012] According to one embodiment of the present invention, a first step is provided on the side of the punching die. The step is a circular ring extending from the bottom of the die toward the side of the die, and the ring is fixedly connected to the die. A pressure ring is provided on the first step. The pressure ring is movably positioned on the first step and connected to the lower die plate via a set screw forging. The pressure ring is a disc-shaped structure with threaded holes arranged in an array around its center. The punching punch is a cylinder with a stepped sidewall.

[0013] To further secure the punching die, the lower template is rectangular with three evenly spaced threaded holes around its center for connection to the pressure ring. The pressure ring, located above the lower template, is a disc-shaped structure with three evenly spaced through-holes and countersunk holes around its center for mounting set screws to secure it to the lower template. A circular countersunk hole is also located in the center of the upper surface of the pressure ring, which is used to secure the punching die using a set screw forging. The pressure ring is clamped above the first step, and the punching die is placed in the center countersunk hole of the lower template. The pressure ring and lower template are completely fixed using set screw forgings. Ultimately, the lower template, pressure ring, and punching die are tightly integrated, completely limiting relative displacement among the three, and avoiding problems with punching accuracy caused by misalignment of structural components.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0022] Example 1:

[0023] See attached Figure 1-4 As shown, a planetary plate punching die that is convenient for processing and removing parts includes: a punching punch 50, a lower template 20, and a punching die 40 installed on the lower template 20. The punching die 40 is surrounded by four holes 401, which are semi-cylindrical notches and are open structures facing the outside of the punching die 40.

[0024] The punching die 40 is provided with a lower step 402, which is a plate extending upward from the outer edge of the upper surface of the die 40. The curvature of the plate is the same as that of the outer surface of the die 40. The lower step 402 is not provided at the location of the opening 401. A circular hole 403 is provided in the center of the die 40, which is a through hole. The die 40 is provided with a jaw 404, which is a curved platform mounted on the inner curved surface of the opening 401. The curved platform is lower than the level of the upper surface of the die 40. The upper surface of the die 40 is provided with a circular array of stepped countersunk holes 405, which are cylindrical indentations provided in the die 40.

[0025] The planetary plate component in the vehicle transmission has a structural feature, that is, it has four slender claws around its periphery and four evenly arranged steps on the bottom surface, so the punching die 40 needs to make corresponding avoidance.

[0026] The four holes 401 provided around the punching die 40 are used to avoid the four slender claws of the forging 10. The holes 401 are open outward, which is convenient for machining and simplifies the processing steps. The lower step 402 provided on the punching die 40 is used to position the forging 10. During the downward punching process of the punching punch 50, if the positioning of the forging 10 deviates, it will cause the stamping position of the forging 10 to be wrong or the stamping accuracy to be too low, which will have a huge impact on the qualified rate of the product, cause waste of resources, increase manufacturing costs and seriously affect production efficiency. Therefore, the positioning effect of the lower step 402 on the forging 10 can improve the stamping accuracy of the forging 10; the circular hole 403 located in the middle of the punching die 40 can make the waste of the forging 10 generated during the stamping process fall from the circular hole 403, and the waste can be cleaned up in time and automatically, avoiding the accumulation of waste generated by stamping that affects the forming of the forging 10, and the circular hole 403 can also serve as an exhaust hole to remove the gas accumulated during the stamping process in real time, avoiding damage to the stamping machine due to high air pressure, thereby improving the service life of the machine and the product qualification rate of the forging 10.

[0027] A 40mm long, 40mm wide, and 20mm deep jaw 404 is provided on a circular arc surface of a perforated portion 401 on the punching die 40. This facilitates the gripping of the forging 10, improving production efficiency. The original planetary plate component was difficult to remove from the die cavity after the punching operation. Forcibly removing the forging 10 using tools would likely damage the forging 10, seriously impacting production efficiency. The punching die 40 now has jaws 404. After the punching operation is complete, personnel can use tools to easily remove the forging 10 through the jaws 404 without damaging the forging 10, significantly improving production efficiency. Four stepped countersunk holes 405 are provided in a circular array on the upper surface of the punching die 40 to avoid steps on the forging 10. A first step 406 cooperates with the lower die plate 20 for centering. A circular countersunk hole of equal size to the first step 406 is provided in the center of the lower die plate 20. The first step 406 can be placed within the circular countersunk hole, achieving centering and improving stamping accuracy.

[0028] A first step 406 is provided on the side of the punching die 40. This step is a circular ring extending from the bottom of the punching die 40 toward the side of the die 40 and is fixedly connected to the die 40. A pressure ring 30 is provided on the first step 406. The pressure ring 30 is movably positioned on the first step 406 and connected to the lower die plate 20 via a set screw forging 60. The pressure ring 30 is a disc-shaped structure with threaded holes 201 arranged in an array around its center. The punching punch 50 is cylindrical, with a stepped sidewall.

[0029] To further secure the punching die 40, the lower template 20 is rectangular and has three evenly spaced threaded holes 201 around its center for connection to the pressure ring 30. The pressure ring 30 is located above the lower template 20 and is a disc-shaped structure with three evenly spaced through holes and countersunk holes around its center for installing fixing screws to secure it to the lower template 20. A circular countersunk hole is also provided in the center of the upper surface of the pressure ring 30 for securing the punching die using a fixing screw forging 60. The pressure ring 30 is clamped above the first step 406, and the punching die 40 is placed in the center countersunk hole of the lower template 20. The pressure ring 30 and the lower template 20 are completely secured using the fixing screw forging 60. Ultimately, the lower template 20, the pressure ring 30, and the punching die 40 are tightly combined together, completely limiting the relative displacement between the three and avoiding problems with punching accuracy caused by position deviation of the structural components.
