Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a stamping mold. Background Technology

[0002] In related technologies, side punching and side trimming of complex-shaped sheet metal parts (such as car doors, rear door outer panels, etc.) are usually performed using stamping dies. Traditional stamping dies achieve the stamping action by driving the wedge slider to move laterally through the upper die. However, when the part to be stamped has a negative angle area or a complex curved surface, the retraction of the wedge during side punching and side trimming interferes with the negative angle of the part, making it impossible to smoothly place, remove, and process the part. Side punching waste also cannot be smoothly discharged due to space constraints. The current solution is to decompose the process into different production processes. After rotating the stamping direction, the number of die processes is increased, which leads to an increase in the production cycle of sheet metal parts and affects the production efficiency of sheet metal parts.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following is for reference. Figures 1-5 Describes a stamping die according to an embodiment of the present invention.

[0020] like Figures 1-5 As shown, the stamping die according to an embodiment of the present utility model includes: a lower die body 98, a pad 30, a wedge 40, a first driving member 10, and a second driving member 20.

[0021] A pad carriage 30 is movably disposed on the lower die body 98 along a first direction; a wedge 40 is movably disposed on the pad carriage 30 along a second direction, which intersects with the first direction; a first drive member 10 and a second drive member 20 can move synchronously closer to or further away from the lower die body 98. The first drive member 10 is configured to stop driving the pad carriage 30 when it moves along the first direction to a preset position, and the second drive member 20 is configured to drive the wedge 40 to move along the second direction for stamping after the pad carriage 30 moves to the preset position.

[0022] As some embodiments of this application, the stamping die of this application can be used to process complex sheet metal parts with negative angles, such as the outer panel of the rear door of a vehicle.

[0023] As some embodiments of this application, the first driving member 10 is correspondingly arranged with the pad vehicle 30, and the second driving member 20 is correspondingly arranged with the wedge 40.

[0024] Car 30 along the first direction (i.e. Figure 3 The pad carriage 30 is movably disposed on the lower mold body 98 (in the X direction shown), that is, the pad carriage 30 is disposed on the lower mold body 98, and the pad carriage 30 is movable along the first direction (i.e., Figure 3 As shown in the X direction, it is movable. As some embodiments of this application, the lower mold body 98 has a first direction (i.e., Figure 3 The guide rail (shown in the X direction) extends, and the pad carriage 30 has a slider. The guide rail and the slider are movably engaged so that the pad carriage 30 can be movably disposed on the lower mold body 98 in the first direction.

[0025] wedge 40 along the second direction (i.e. Figure 3 The wedge 40 is movably mounted on the pad 30 in the Y direction (as shown), that is, the wedge 40 is mounted on the pad 30, and the wedge 40 is mounted along the second direction (i.e., Figure 3 As shown in the Y direction, the pad vehicle 30 is movable. As some embodiments of this application, the pad vehicle 30 has a second direction (i.e., Figure 3 A guide rail extending in the Y direction (as shown), and a wedge 40 having a slider, the guide rail and the slider being movably engaged so that the wedge 40 can move along the second direction (i.e., Figure 3 The Y-direction shown is movable and mounted on the pad vehicle 30.

[0026] The second direction (i.e.) Figure 3 The Y direction shown) and the first direction (i.e. Figure 3 The second direction (i.e., the X direction shown) intersects with the X direction, that is, the second direction (i.e., the X direction shown) intersects with the X direction. Figure 3 The extension of the line in the Y direction (as shown) and the first direction (i.e. Figure 3 The extensions of the lines in the X direction (as shown) can intersect. As some embodiments of this application, the first direction (i.e. Figure 3 The X direction shown can be the horizontal direction, and the second direction (i.e., Figure 3 The Y direction shown) and the first direction (i.e. Figure 3 The X-direction shown intersects with an angle.

[0027] The first driving member 10 and the second driving member 20 can move synchronously closer to or further away from the lower die body 98. That is, the first driving member 10 and the second driving member 20 can move synchronously closer to the lower die body 98, and the first driving member 10 and the second driving member 20 can move synchronously further away from the lower die body 98. As some embodiments of this application, the synchronous movement of the first driving member 10 and the second driving member 20 closer to the lower die body 98 enables the stamping die to perform stamping. The stamping can be, but is not limited to, processes such as side punching and side trimming.

[0028] The first drive unit 10 is capable of driving the vehicle 30 along a first direction (i.e., Figure 3 When the first drive member 10 moves close to the lower mold body 98, it can drive the pad carriage 30 to move along the first direction to the preset position. When the pad carriage 30 moves to the preset position, the first drive member 10 stops driving the pad carriage 30.

[0029] The second driving component 20 can drive the wedge 40 along the second direction (i.e., after the trolley 30 moves to the preset position) Figure 3 The first drive member 10 moves closer to the lower die body 98 to perform stamping. Specifically, the first drive member 10 can move closer to the lower die body 98 to drive the pad carriage 30 to move along the first direction to a preset position. When the pad carriage 30 moves along the first direction to the preset position, the first drive member 10 stops driving the pad carriage 30 and continues to move closer to the lower die body 98 together with the second drive member 20. The second drive member 20 moves closer to the lower die body 98 to drive the wedge 40 to move along the second direction to perform stamping.

[0030] As some embodiments of this application, the first driving member 10 and the pad carriage 30, and the second driving member 20 and the wedge 40 can all be driven by the inclined surface cooperation, so that when the first driving member 10 stops driving the pad carriage 30 and continues to move closer to the lower mold body 98 together with the second driving member 20, the first driving member 10 no longer drives the pad carriage 30, and the second driving member 20 begins to drive the wedge 40.

[0031] As some embodiments of this application, the first driving member 10 and the second driving member 20 can be logically controlled to achieve the following: when the first driving member 10 drives the pad carriage 30 to move along the first direction to a preset position, it stops driving the pad carriage 30; after the pad carriage 30 moves to the preset position, the second driving member 20 drives the wedge 40 to move along the second direction for stamping. For example, when the pad carriage 30 moves to the preset position, the first driving member 10 can be controlled to move along the first direction to be misaligned with the pad carriage 30. This allows the first driving member 10 to stop driving the pad carriage 30 and continue to move closer to the lower die body 98 together with the second driving member 20. In this case, the first driving member 10 no longer drives the pad carriage 30, while the second driving member 20 begins to drive the wedge 40.

[0032] It should be noted that by enabling the first driving member 10 to drive the pad carriage 30 to move along the first direction to a preset position, and enabling the second driving member 20 to drive the wedge 40 to move along the second direction for stamping after the pad carriage 30 has moved to the preset position, it is possible to make the pad carriage 30 move along the first direction (i.e., ...) even when the part to be stamped 97 has a negative angle. Figure 3 The wedge 40 is moved along the X direction (as shown), moving the entire wedge 40 away from the negative angle region of the part to be stamped 97, so that the entire wedge 40 moves along the second direction (i.e. Figure 3 The lateral stamping in the Y direction (as shown) provides space, which greatly reduces the probability of interference with the wedge 40 when picking up and putting down the part to be stamped 97. Moreover, this setting can facilitate the smooth sliding and discharge of the scrap 71, which is conducive to improving the production efficiency of the part to be stamped 97.

[0033] Moreover, the stamping die of this application can complete complex side punching and side trimming processes in a single sequence, while meeting the four-process production requirements of general equipment. From the perspective of tooling development and process route, it can save mold development costs and significantly shorten the development cycle. From the production perspective, it can save mold storage space and line mold change time, significantly speed up the production cycle and reduce production costs.

[0034] Therefore, by enabling the first driving member 10 to drive the pad carriage 30 to move along the first direction to a preset position, and enabling the second driving member 20 to drive the wedge 40 to move along the second direction for stamping after the pad carriage 30 has moved to the preset position, there will be no interference with the part to be stamped 97 when there is a negative angle. This facilitates the picking and placing and processing of the part to be stamped 97, significantly reduces the production cycle of the part to be stamped 97, and improves the production efficiency of the part to be stamped 97.

[0035] In some embodiments of this utility model, such as Figure 4As shown, the first driving member 10 has a first mating surface 11, and the pad vehicle 30 has a second mating surface 321. The first mating surface 11 and the second mating surface 321 are adapted to each other. The first driving member 10 can drive the pad vehicle 30 to move along the first direction by engaging the first mating surface 11 and the second mating surface 321.

[0036] As some embodiments of this application, such as Figure 4 As shown, the first mating surface 11 is planar, and the second mating surface 321 is planar. The first mating surface 11 and the second mating surface 321 are parallel, and the first mating surface 11 has an angle with the first direction. The first mating surface 11 and the second mating surface 321 are adapted to each other, and the first mating surface 11 can contact the surface of the second mating surface 321. When the first driving member 10 moves closer to the lower mold body 98, it can cause the first mating surface 11 to move towards the lower mold body 98. Since the first mating surface 11 and the second mating surface 321 are adapted to each other, the second mating surface 321 will contact the first mating surface 11 and slide relative to it. Since the pad carriage 30 is slidably disposed on the lower mold body 98, the horizontal component force generated when the first mating surface 11 contacts the second mating surface 321 directly pushes the pad carriage 30 to move, thereby enabling the first driving member 10 to drive the pad carriage 30 along the first direction (i.e., Figure 3 Move in the X direction (as shown).

[0037] This configuration can convert the vertical motion of the first driving component 10 into the horizontal motion of the pad carriage 30. It has a simple structure and does not require an additional force transmission mechanism. The simple structure can significantly reduce the maintenance cost of the stamping die.

[0038] In some embodiments of this utility model, such as Figure 4 As shown, the pad vehicle 30 also has a third mating surface 322. Along the moving direction of the first driving member 10, the third mating surface 322 is connected to the lower end of the second mating surface 321, and the third mating surface 322 is parallel to the moving direction of the first driving member 10.

[0039] Wherein, along the moving direction of the first driving member 10 (i.e. Figure 3 (As shown in the Z direction), the second mating surface 321 has an upper end and a lower end, and the third mating surface 322 is connected to the lower end of the second mating surface 321. In other words, the third mating surface 322 is located below the second mating surface 321. Furthermore, the third mating surface 322 is parallel to the moving direction of the first driving member 10.

[0040] By making the third mating surface 322 parallel to the moving direction of the first driving member 10, after the first mating surface 11 separates from the second mating surface 321, the first driving member 10 can move along the extending direction of the third mating surface 322. The first driving member 10 will not continue to drive the pad carriage 30 to move, so that the pad carriage 30 is in a preset position. It can also limit the pad carriage 30 to reduce the risk of the pad carriage 30 automatically resetting before the wedge 40 completes the stamping process. This is beneficial to improving the accuracy of the pad carriage 30's position and the reliability of the stamping die.

[0041] In some embodiments of this utility model, such as Figure 4 As shown, the cushion vehicle 30 includes: a cushion vehicle body 31 and a first passive member 32. The first passive member 32 is disposed on the cushion vehicle body 31 and has a second mating surface 321 and a third mating surface 322.

[0042] The first passive member 32 is disposed on the vehicle body 31. As in some embodiments of this application, the first passive member 32 is detachably connected to the vehicle body 31. For example, the first passive member 32 and the vehicle body 31 are detachably connected by bolts or snap-fit. The first passive member 32 has a second mating surface 321 and a third mating surface 322, that is, both the second mating surface 321 and the third mating surface 322 are formed on the first passive member 32.

[0043] It is understandable that the second mating surface 321 and the first mating surface 11 will slide relative to each other, which will inevitably cause wear on the second mating surface 321. By making the pad car 30 include the pad car body 31 and the first passive component 32, and by placing the first passive component 32 on the pad car body 31, it is easier to replace the first passive component 32, reducing the maintenance difficulty of the stamping die. In addition, this allows the first passive component 32 of different materials to be replaced according to the stamping material and process parameters, which is beneficial to improving the adaptability of the stamping die.

[0044] In some embodiments of this utility model, such as Figure 5 As shown, the second driving member 20 has a fourth mating surface 21, and the wedge 40 has a fifth mating surface 421. The fourth mating surface 21 and the fifth mating surface 421 are adapted to each other. The fourth mating surface 21 and the fifth mating surface 421 are mated to enable the second driving member 20 to drive the wedge 40 to move in the second direction.

[0045] As some embodiments of this application, such as Figure 5As shown, the fourth mating surface 21 is planar, and the fifth mating surface 421 is planar. The fourth mating surface 21 and the fifth mating surface 421 are parallel, and the fourth mating surface 21 has an angle with the second direction. The fourth mating surface 21 and the fifth mating surface 421 are adapted to each other. When the second driving member 20 moves closer to the lower mold body 98, it can cause the fourth mating surface 21 to move towards the lower mold body 98. Since the fourth mating surface 21 and the fifth mating surface 421 are adapted to each other, the fourth mating surface 21 will contact the fifth mating surface 421 and slide relative to it. Since the wedge 40 is slidably provided on the pad 30, the component force generated when the fourth mating surface 21 contacts the fifth mating surface 421 directly pushes the wedge 40 to move, thereby enabling the second driving member 20 to drive the wedge 40 along the second direction (i.e., Figure 3 (As shown in the Y direction) moves to perform stamping.

[0046] This configuration can convert the vertical movement of the second drive component 20 into the stamping direction movement of the wedge 40 without the need for an additional force transmission mechanism. The structure is simple and can significantly reduce the maintenance cost of the stamping die.

[0047] In some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the wedge 40 includes: a wedge body 41 and a second passive member 42. The second passive member 42 is disposed on the wedge body 41 and has a fifth mating surface 421.

[0048] The second passive member 42 is disposed on the wedge body 41. As in some embodiments of this application, the second passive member 42 is detachably connected to the wedge body 41, for example, by means of bolt connection, snap-fit ​​connection, etc. The second passive member 42 has a fifth mating surface 421, that is, the fifth mating surface 421 is formed on the second passive member 42.

[0049] It is understandable that the fourth mating surface 21 and the fifth mating surface 421 will slide relative to each other, causing the fifth mating surface 421 to wear. By making the wedge 40 include the wedge body 41 and the second passive member 42, and by placing the second passive member 42 on the wedge body 41, it is easier to replace the second passive member 42, reducing the maintenance difficulty of the stamping die. Furthermore, this allows the second passive member 42 of different materials to be replaced according to the stamping material and process parameters, which is beneficial to improving the adaptability of the stamping die.

[0050] In some embodiments of this utility model, such as Figure 3 As shown, the wedge 40 also includes a pressure block 50, which is disposed on the wedge body 41 and is adapted to contact the workpiece to be stamped.

[0051] The material of the pressure block 50 can be, but is not limited to, polyurethane, engineering plastics, alloy tool steel, etc. As some embodiments of this application, the material of the pressure block 50 is polyurethane.

[0052] The pressure block 50 is disposed on the wedge body 41. As some embodiments of this application, the pressure block 50 and the wedge body 41 are detachably connected. For example, the pressure block 50 and the wedge body 41 are connected by bolts.

[0053] By including a pressure block 50 in the wedge 40 and placing the pressure block 50 on the wedge body 41, the stamping accuracy can be significantly improved, the surface quality of the part to be stamped 97 can be improved, and the risk of damaging the part to be stamped 97 during stamping can be reduced.

[0054] In some embodiments of this utility model, such as Figures 3-5 As shown, the stamping die also includes a limiting member 60, which is located on the lower die body 98. When the pad 30 moves to the preset position, it can contact and limit the limiting member 60.

[0055] The limiting member 60 is provided on the lower mold body 98. The connection method between the limiting member 60 and the lower mold body 98 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of this application, the limiting member 60 and the lower mold body 98 are connected by bolt connection.

[0056] When the pad 30 moves to the preset position, it can contact and limit the limit member 60. In other words, the limit member 60 can limit the pad 30 so that the pad 30 is limited to the preset position.

[0057] As some embodiments of this application, the stamping die further includes: a second limiting member 61, which is disposed on the pad carriage 30, and the wedge 40 can contact and limit the movement of the wedge 61 when it moves to the stamping position.

[0058] This setting can significantly improve the accuracy of the preset position of the pad car 30, thereby improving the accuracy of the wedge 40 stamping and improving the production quality of the stamped part 97.

[0059] Understandably, during the stamping process, after the first mating surface 11 separates from the second mating surface 321, the pad carriage 30 is located between the limiting member 60 and the first driving member 10. This can reduce the risk of the pad carriage 30 shifting out of position, so that the wedge 40 is in a precise position, which is beneficial to improving the production quality of the stamped part 97.

[0060] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the stamping die also includes: an upper die body, a first driving member 10 and a second driving member 20 both connected to the upper die body, the upper die body being able to move closer to or further away from the lower die body 98 so that the first driving member 10 and the second driving member 20 move closer to or further away from the lower die body 98 synchronously, and the length of the first driving member 10 is greater than the length of the second driving member 20.

[0061] The stamping die also includes an upper die body. Both the first driving component 10 and the second driving component 20 are connected to the upper die body. The connection method between the first driving component 10 and the upper die body can be, but is not limited to, welding or bolting. As some embodiments of this application, the first driving component 10 is connected to the upper die body by bolting. The connection method between the second driving component 20 and the upper die body can be, but is not limited to, welding or bolting. As some embodiments of this application, the second driving component 20 is connected to the upper die body by bolting.

[0062] Along the third direction (i.e. Figure 3 (As shown in the Z direction), the upper mold body can move closer to the lower mold body 98 so that the first driving member 10 and the second driving member 20 move closer to the lower mold body 98 synchronously, and the upper mold body can move away from the lower mold body 98 so that the first driving member 10 and the second driving member 20 move away from the lower mold body 98 synchronously.

[0063] It should be noted that along the third direction (i.e. Figure 3 (as shown in the Z direction), the length of the first driving member 10 is greater than the length of the second driving member 20, that is, along the third direction (i.e. Figure 3 (As shown in the Z direction), both the first driving member 10 and the second driving member 20 have an end close to the lower mold body 98 and an end far from the lower mold body 98. The distance between the end of the first driving member 10 close to the lower mold body 98 and the lower mold body 98 is less than the distance between the end of the second driving member 20 close to the lower mold body 98 and the lower mold body 98.

[0064] When the upper mold body moves closer to the lower mold body 98, the first driving member 10 moves along a third direction (i.e. Figure 3 The first driven member 10 (in the Z direction shown) first contacts the first passive member 32. At this time, since the length of the first driven member 10 is greater than the length of the second driven member 20, the second driven member 20 has not yet contacted the second passive member 42. The first mating surface 11 and the second mating surface 321 cooperate to make the first driven member 10 drive the pad vehicle 30 along the first direction (i.e., the Z direction shown). Figure 3The upper mold body moves to a preset position (in the X direction shown). When the pad 30 moves to the preset position, the pad 30 can contact the limiting member 60 to limit it, and the first mating surface 11 separates from the second mating surface 321. Then, as the upper mold body continues to move closer to the lower mold body 98, the second driving member 20 contacts the second passive member 42, and the fourth mating surface 21 engages with the fifth mating surface 421 so that the second driving member 20 can drive the wedge 40 along the second direction (i.e., the X direction shown). Figure 3 The device moves in the Y direction (as shown) to perform stamping.

[0065] As some embodiments of this application, while the first mating surface 11 and the second mating surface 321 are separated, the pad vehicle 30 can contact the limiting member 60 to limit it, and at the same time the second driving member 20 contacts the second passive member 42.

[0066] This configuration allows the stamping die to have a reasonable mechanical timing, enabling the first drive component 10 to drive the pad 30 first, and the second drive component 20 to drive the wedge 40 later. Moreover, this configuration has a simple structure, does not require additional complex structural components, has low maintenance costs, and helps to improve the reliability of the stamping die.

[0067] In some embodiments of this utility model, the stamping die further includes: a first elastic element, which is connected between the pad carriage 30 and the lower die body 98. After the first driving member 10 is separated from the pad carriage 30, the first elastic element is used to drive the pad carriage 30 to reset.

[0068] The first elastic element connects the pad 30 and the lower mold body 98. As some embodiments of this application, the lower mold body 98 has a first direction (i.e., Figure 3 The guide rail extends in the X direction (as shown). The pad carriage 30 has a slider. The guide rail and the slider are movable and engaged. The first elastic element is connected between the guide rail and the slider. When the first driving member 10 separates from the pad carriage 30 (this separation means that the first mating surface 11 separates from the second mating surface 321 and the third mating surface 322. This separation exists during the process of the first driving member 10 moving away from the lower mold body 98), the first elastic element can drive the pad carriage 30 to reset from the preset position along the first direction.

[0069] This configuration allows for a reasonable stamping die structure, enabling the padding carriage 30 to automatically reset when the first drive component 10 separates from the padding carriage 30. This is beneficial for improving the automation level of the stamping die and the production efficiency of the parts to be stamped.

[0070] In some embodiments of this utility model, it further includes: a second elastic member, which is connected between the wedge 40 and the pad 30. After the second driving member 20 is separated from the wedge 40, the second elastic member is used to drive the wedge 40 to reset.

[0071] The second elastic element is connected between the wedge 40 and the pad 30. As some embodiments of this application, the pad 30 has a second direction (i.e., Figure 3 The guide rail extends in the Y direction (as shown), the wedge 40 has a slider, the guide rail and the slider are movablely engaged, and the second elastic element is connected between the guide rail and the slider. When the second driving member 20 separates from the wedge 40 (this separation refers to the separation of the fourth mating surface 21 from the fifth mating surface 421, which exists during the process of the second driving member 20 moving away from the lower mold body 98), the second elastic element can drive the wedge 40 to reset along the second direction.

[0072] This configuration allows for a reasonable stamping die structure, enabling the wedge 40 to automatically reset when the second drive component 20 separates from the wedge 40, which is beneficial for improving the automation level of the stamping die and the production efficiency of the parts to be stamped.

[0073] As some embodiments of this application, such as Figure 5 As shown, the stamping die also includes a scrap chute 70, and the scrap 71 generated by the wedge 40 in the second direction during the stamping of the workpiece 97 can fall into the scrap chute 70 and be discharged along the scrap chute 70.
