Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and more specifically, to a stamping die suitable for parts of different specifications. Background Technology

[0002] Stamping dies are production tooling equipment designed to produce corresponding parts based on product data and shape characteristics, after process planning and structural design. Existing stamping dies correspond one-to-one with stamped parts; typically, one die can only stamp parts of a specific specification. To produce different parts, different dies are required.

[0003] In the automotive industry, the manufacture of various parts requires the use of multiple stamping dies. However, die development involves several stages, including product analysis, process design, structural design, foaming, casting, machining, assembly, off-line product development, and mainline product development, resulting in a lengthy development cycle. Even for the same type of part, there are multiple models with different specifications and dimensions. To reduce R&D and production costs, it is necessary to improve the applicability of stamping dies. Utility Model Content

[0004] To overcome the problem in the prior art that the same mold is difficult to apply to parts of different specifications, this utility model provides a stamping mold that is applicable to parts of different specifications, and can be used to process at least two different specifications of parts, thus saving mold costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stamping die suitable for parts of different specifications, including an upper die and a lower die. The upper die is provided with a first cutter, a second cutter and a common cutter at different positions. The first cutter and the common cutter together form the outer contour shape of a part of a first specification. The second cutter and the common cutter together form the outer contour shape of a part of a second specification. The first cutter is located near the edge of the upper die relative to the second cutter, and the length of the first cutter extending toward the lower die is greater than the length of the second cutter extending toward the lower die. The lower die is provided with a first cutting edge, a second cutting edge and a common cutting edge. The vertical positions of the first cutting edge, the second cutting edge and the common cutting edge correspond to the first cutter, the second cutting edge and the common cutter, respectively.

[0006] In the technical solution of this utility model, when the upper and lower dies are closed at the first height, the first cutter and the common cutter contact the blank to be processed, thereby stamping and cutting the blank to obtain a part of the first specification. Since the second cutter is shorter, it will not contact the blank, and at this time the second cutter will not affect the processing of the part of the first specification. When the upper and lower dies are closed at the second height, the second cutter and the common cutter contact the blank to be processed, thereby stamping and cutting the blank to obtain a part of the second specification. Since the first cutter is located on the outside compared to the second cutter, the first cutter is not in the enclosed area of ​​the part of the second specification, and does not affect the processing of the part of the second specification. The stamping die of this solution can realize the processing of at least two different specifications of parts.

[0007] Furthermore, the lower mold is provided with a first positioner and a common positioner, which are used to position the first specification part.

[0008] In this scheme, the first specification part is positioned by a first positioner and a common positioner to facilitate stamping.

[0009] Furthermore, the lower mold is provided with a liftable second positioner, which is located closer to the interior of the lower mold than the first positioner. The second positioner and the shared positioner are used to position the second specification part.

[0010] In this scheme, the second specification part is positioned by a second positioner and a common positioner to facilitate stamping. The second positioner can play a positioning role when it is raised, and will not cause structural interference when the first specification part is processed when it is lowered.

[0011] Furthermore, the second positioner is connected to a lifting drive mechanism, the fixed end of which is connected to the lower mold, and the movable end of which is connected to the second positioner.

[0012] In this solution, the second positioner is driven to move up and down by a lifting drive mechanism, which can position the second specification part without affecting the processing of the first specification part.

[0013] Furthermore, the lifting drive mechanism is a cylinder, and the cylinder is connected to an external air source device.

[0014] In this solution, a stable lifting force is generated by connecting an external air source device through a cylinder.

[0015] Furthermore, a control valve for controlling the lifting and lowering of the cylinder is connected in the air circuit of the cylinder, and the control valve is located on one side of the lower mold.

[0016] In this solution, the lifting and lowering states of the cylinder can be switched by a control valve, thereby controlling the lifting and lowering states of the second positioner to meet the processing requirements of the first specification part and the second specification part respectively.

[0017] Furthermore, the upper mold is provided with a third cutter, and the lower mold is provided with a third cutting edge corresponding to the third cutter in the vertical direction. The third cutter is located near the edge of the upper mold relative to the first cutter, and the length of the third cutter extending toward the lower mold is greater than the length of the first cutter extending toward the lower mold.

[0018] In this scheme, the first cutting edge, the second cutting edge, and the common cutting edge engage with the first cutting tool, the second cutting edge, and the common cutting tool respectively during the stamping process to cut off the blank and form the outline shape of the part.

[0019] Furthermore, the lower mold is provided with a waste trough on its side for discharging waste material.

[0020] In this solution, a waste trough is provided to facilitate the discharge of waste generated during stamping and to prevent waste blockage.

[0021] Furthermore, the first locator and the shared locator are arranged circumferentially around the first specification part.

[0022] In this scheme, the first locator and the common locator arranged around it can achieve a stable positioning function, so as to facilitate the processing of the first specification part.

[0023] Furthermore, the second locator and the common locator are arranged circumferentially around the second specification part.

[0024] In this scheme, the second locator and the common locator arranged around it can achieve a stable positioning function, so as to facilitate the processing of the second specification parts.

[0025] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a stamping die suitable for parts of different specifications. When the upper and lower dies are closed at the first height, the first cutter and the common cutter contact the blank to be processed, thereby stamping and cutting the blank to obtain a part of the first specification. Since the second cutter is shorter, it does not contact the blank, and at this time, the second cutter does not affect the processing of the part of the first specification. When the upper and lower dies are closed at the second height, the second cutter and the common cutter contact the blank to be processed, thereby stamping and cutting the blank to obtain a part of the second specification. Since the first cutter is located on the outside compared to the second cutter, the first cutter is not in the enclosed area of ​​the part of the second specification, and does not affect the processing of the part of the second specification. Each cutting edge is used to cooperate with each cutter for cutting. The stamping die of this solution can realize the processing of at least two different specifications of parts, saving die costs.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0029] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "long," and "short" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1 refer to Figures 1 to 3 This embodiment discloses a stamping die suitable for parts of different specifications, including an upper die 1 and a lower die 2. The upper die 1 is provided with a first cutter 11, a second cutter 12 and a common cutter 13 at different positions. The first cutter 11 and the common cutter 13 together form the outer contour shape of a part of a first specification, and the second cutter 12 and the common cutter 13 together form the outer contour shape of a part of a second specification. The first cutter 11 is located near the edge of the upper die 1 relative to the second cutter 12, and the length of the first cutter 11 extending toward the lower die 2 is greater than the length of the second cutter 12 extending toward the lower die 2. The lower die 2 is provided with a first cutting edge 24, a second cutting edge 25 and a common cutting edge 26. The vertical positions of the first cutting edge 24, the second cutting edge 25 and the common cutting edge 26 correspond to the first cutter 11, the second cutting edge 25 and the common cutter 13, respectively.

[0031] In this embodiment, when the upper die 1 and the lower die 2 are closed at the first height, the first cutter 11 and the common cutter 13 contact the blank to be processed, thereby stamping and cutting the blank to obtain a part of the first specification. Since the second cutter 12 is shorter, it will not contact the blank, and at this time the second cutter 12 will not affect the processing of the part of the first specification. When the upper die 1 and the lower die 2 are closed at the second height, the second cutter 12 and the common cutter 13 contact the blank to be processed, thereby stamping and cutting the blank to obtain a part of the second specification. Since the first cutter 11 is located on the outside compared to the second cutter 12, the first cutter 11 is not in the enclosed area of ​​the part of the second specification, and does not affect the processing of the part of the second specification. The stamping die of this solution can realize the processing of at least two different specifications of parts.

[0032] In practical use, the stamping die is mounted on a press, which provides power for the die's closing and opening. The press can control various closing heights via a program; in this embodiment, the die corresponds to the first height and the second height, respectively, thus enabling the production of two types of parts from a single die. It is understood that while the stamping die in this embodiment has the function of producing two specifications of parts, it does not mean that it can produce two types of parts simultaneously. In other embodiments, a third cutter may be included, and this third cutter is closer to the edge of the upper die 1 than the second cutter 12. The length of the first cutter 11 extending towards the lower die 2 is greater than the length of the second cutter 12 extending towards the lower die 2, allowing the stamping die to be used to produce three different specifications of parts.

[0033] Similarly, by increasing the number of cutters, more parts of different specifications can be produced. For example, in some embodiments, the upper mold 1 is provided with a third cutter, and the lower mold 2 is provided with a third cutting edge corresponding to the third cutter in the vertical direction. The third cutter is located near the edge of the upper mold 1 relative to the first cutter, and the length of the third cutter extending toward the lower mold 2 is greater than the length of the first cutter extending toward the lower mold. This allows three different specifications of parts to be produced using one set of molds.

[0034] Existing stamping dies are typically only suitable for the same part. Even if two parts have only slight dimensional differences, different stamping dies are required. The stamping die in this embodiment, by setting multiple cutting blades, can be used to produce parts of different specifications. This avoids the mold-making costs caused by slight differences in part dimensions and improves economic efficiency.

[0035] refer to Figure 3 In this embodiment, the first cutting edge 24, the second cutting edge 25, and the common cutting edge 26 engage with the first cutting blade 11, the second cutting edge 25, and the common cutting blade 13 respectively during stamping to cut the blank and form the outline shape of the part. The cutting edge can be a notch or groove corresponding to the cutting blade formed in the lower die 2, or an edge portion of the lower die 2. When the cutting blade enters the cutting edge position, the edges of the two engage to cut the part. (Reference) Figure 3 In this embodiment, the first cutting edge 24 and the common cutting edge 26 are located at the edge of the lower mold 2, and the second cutting edge 25 is a groove formed in the lower mold 2, so as to facilitate the processing of a slightly smaller second specification part.

[0036] refer to Figure 3 The lower die 2 is provided with a first positioner 21 and a common positioner 23, which are used to position a first specification part. In this embodiment, the first specification part is positioned by the first positioner 21 and the common positioner 23 to facilitate stamping.

[0037] refer to Figure 3 The lower die 2 is equipped with a liftable second positioner 22. The second positioner 22 is located relatively close to the interior of the lower die 2 relative to the first positioner 21. The second positioner 22 and the shared positioner 23 are used to position the second specification part. In this embodiment, the second specification part is positioned by the second positioner 22 and the shared positioner 23 to facilitate stamping. When the second positioner 22 is raised, it can play a positioning role. When the second positioner 22 is lowered, it will not cause structural interference when processing the first specification part. When the second positioner 22 is raised, it can play a positioning role for the second specification part. When the second positioner 22 is lowered, it can be located inside the lower die 2. The lowered second positioner 22 does not contact the first specification part, so it does not affect the processing of the first specification part.

[0038] refer to Figure 3 The second positioner 22 is connected to a lifting drive mechanism. The fixed end of the lifting drive mechanism is connected to the lower mold 2, and the moving end of the lifting drive mechanism is connected to the second positioner 22. In this embodiment, the second positioner 22 is driven to move up and down by the lifting drive mechanism, which can position the second specification part without affecting the processing of the first specification part.

[0039] In some embodiments, the lifting drive mechanism can be an electric cylinder, a hydraulic cylinder, etc. In this embodiment, the lifting drive mechanism is a pneumatic cylinder, which is connected to an external air source device. In this embodiment, a stable lifting force is generated by connecting the pneumatic cylinder to the external air source device. The pneumatic cylinder has strong driving force and can be used in conjunction with existing air source devices in the production workshop, which is quite convenient.

[0040] refer to Figure 3 The first locator 21 and the common locator 23 are arranged circumferentially around the first specification part. In this embodiment, the first locator 21 and the common locator 23 arranged around each other can achieve a stable positioning function, so as to facilitate the processing of the first specification part.

[0041] refer to Figure 3 The second locator 22 and the common locator 23 are arranged circumferentially around the second specification part. In this embodiment, the surrounding second locator 22 and the common locator 23 can achieve a stable positioning function, so as to facilitate the processing of the second specification part.

[0042] Example 2 refer to Figures 1 to 3 This embodiment is similar to Embodiment 1, except that in this embodiment, a control valve 3 for controlling the lifting and lowering of the cylinder is connected to the air circuit of the cylinder, and the control valve 3 is located on one side of the lower mold 2. In this embodiment, the control valve 3 can have three positions: the first position corresponds to the processing of a part of the first specification, the second position corresponds to the processing of a part of the second specification, and the third position can be a stop position. The connection method between the control valve 3 and the air circuit of the cylinder is prior art and will not be described further here. In this embodiment, the control valve 3 is located on one side of the lower mold 2 for easy operation by the operator. In this embodiment, the lifting and lowering state of the cylinder can be switched through the control valve 3, thereby controlling the lifting and lowering state of the second positioner 22 to meet the processing requirements of the first and second specification parts respectively.

[0043] Example 3 refer to Figures 1 to 3This embodiment is similar to Embodiment 1, except that the lower die 2 has a waste material trough 27 on its side for discharging waste. In this embodiment, the waste material trough 27 is provided to facilitate the discharge of waste generated during stamping and prevent waste blockage. The waste material trough 27 is located outside the edge of the cut-off part blank, and the cut-off waste material falls naturally into the waste material trough 27 for collection. The waste material trough 27 can be set slightly downward to facilitate the discharge and collection of waste material. A waste material collection box can be set below the waste material trough 27 to facilitate waste material recycling.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
