[0002] In the process of product production and processing, usually a punch enters a die cavity to stretch out the product and bring it to a stripping block for stripping. In the prior art, when the punch is still in the product, at this time a manipulator has to clamp the product to prevent it from falling down. Since the upper opening part of the product is not completely flat at this time, after the upper opening part of the product is completely separated from the punch and the manipulator has clamped the product and the product will not continue to fall, then the upper opening part of the product contacts and abuts against the stripping block. When the manipulator horizontally transports the product, the upper opening part of the product will rub against the stripping block, resulting in the inclination of the product position, which will affect the next-step processing, handling accuracy and the forming of the product. Aiming at the technical problems that the product abuts against the stripping block and generates friction during the above-mentioned stripping process, it is urgent to improve the existing stripping technology.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0026] Please refer to Figure 1 , Figure 1This is the first schematic diagram of the stamping die and the product 300 provided by the embodiments of the present utility model. The first object of the present utility model is to provide a stamping die, which includes: an upper die 10, a lower die, and a material discharging mechanism. The upper die 10 is provided with a punch 110. The upper die 10 can move up and down under the action of a power source such as a stamping machine or a hydraulic press. The punch 110 can move up and down with the upper die 10 so as to enter the concave die to stretch out the product 300, and cooperate with the material discharging mechanism to perform the material discharging action. The lower die is provided with a cavity 400 adapted to the punch 110 to form the product 300, and the product 300 is wrapped around the punch 110 when the product 300 is just formed. The material discharging mechanism includes a first material discharging member 220a and a second material discharging member 220b disposed corresponding to the periphery of the punch 110. The second material discharging member 220b is fixed on the lower die, and the first material discharging member 220a is movably connected to the second material discharging member 220b so that the product 300 is separated from the punch 110 and the first material discharging member 220a.

[0027] Compared with the prior art, the beneficial effects of the stamping die proposed by the present utility model are as follows: By setting the material discharging mechanism into a first material discharging member 220a and a second material discharging member 220b, and the second material discharging member 220b is fixed on the lower die. When the punch 110 passes through the second material discharging member 220b, the second material discharging member 220b separates the punch 110 from the product 300. Through the movable connection between the first material discharging member 220a and the second material discharging member 220b, the product 300 is separated from the first material discharging member 220a, so as to realize the complete detachment of the product 300 from the stamping die, ensure the normal operation of the subsequent handling and processing of the product 300, reduce the defective rate of the product 300, stabilize the production and processing process of the product 300, and improve the production efficiency of the product 300.

[0028] Among them, when the product 300 is formed and the stamping die is opened, the first material discharging member 220a is set away from the second material discharging member 220b at this time. During the process of the stamping die continuing to open to a preset position, the first material discharging member 220a will approach the second material discharging member 220b until the upper die 10 moves to the preset position. By making the first material discharging member 220a move away from the second material discharging member 220b again, the product 300 can be separated from the punch 110, and then by making the first material discharging member 220a approach the second material discharging member 220b again, the product 300 can be completely separated from the first material discharging member 220a. Thus, the material discharging mechanism will not affect the subsequent handling operation of the manipulator (during the separation process of the product 300 from the punch 110 and the first material discharging member 220a, the manipulator will assist in clamping the product 300 to prevent the product 300 from falling under the action of gravity and the first material discharging member 220a), so that the subsequent handling operation can be completed efficiently and accurately, thereby improving the processing quality.

[0029] Specifically, as Figure 2 shown, Figure 2 Figure 2 is the second schematic diagram of the stamping die and the product 300 provided by the embodiment of the present utility model. When the punch 110 is a cylinder, the cavity 400 of the lower die is designed as a cylindrical cavity structure. In addition, when the punch 110 is a cuboid or other shape, the cavity 400 of the lower die is designed as a cavity structure adapted thereto, and the structure of the cavity 400 is also adapted to the shape and size of the product 300 to facilitate the precise forming of the product 300.

[0030] Please refer to Figure 2 and Figure 3 , Figure 3 Figure 3 is a connection schematic diagram of the first ejector 220a, the driving assembly 210, and the upper die 10 provided by the embodiment of the present utility model. As an implementation manner, the stamping die further includes a driving assembly 210, and the driving assembly 210 is drivingly connected to the first ejector 220a to move the first ejector 220a closer to or away from the second ejector 220b. Specifically, when the punch 110 moves upward following the upper die 10, and the punch 110 drives the product 300 to move upward, during this process, the upper part of the product 300 gradually abuts against the first ejector 220a, and the first ejector 220a abuts against the second ejector 220b. Since the second ejector 220b is fixedly arranged on the lower die, at this time, when the punch 110 continues to move upward, the punch 110 is gradually separated from the product 300, and at this time, the manipulator starts to move to clamp the product 300.

[0031] Please refer to Figure 3 again. The driving assembly 210 includes a first driving member 210a. The upper die 10 is connected to the first ejector 220a through the first driving member 210a. When the upper die 10 moves upward, the first driving member 210a generates a first ejection driving force. By setting the first driving member 210a to provide the first ejection driving force, the upper die 10 can drive the first ejector 220a to move upward, which is beneficial to promoting the separation of the first ejector 220a from the product 300.

[0032] Please refer to Figure 4 , Figure 4It is a schematic longitudinal cross-section view of the stamping die provided by an embodiment of the present utility model. As an implementation manner, the driving assembly 210 includes a second driving member 210b. Both ends of the second driving member 210b are respectively connected to the first material ejecting member 220a and the second material ejecting member 220b. The first material ejecting member 220a is disposed below the second material ejecting member 220b. The second driving member 210b is a driving structure with variable length, such that the first material ejecting member 220a can approach or move away from the second material ejecting member 220b. When the first material ejecting member 220a approaches the second material ejecting member 220b, the second driving member 210b generates a second material ejection driving force, and the second material ejection driving force can cause the first material ejecting member 220a to move away from the second material ejecting member 220b.

[0033] Optionally, the first driving member 210a and the second driving member 210b can adopt power mechanisms such as air cylinders or motors.

[0034] As an implementation manner, the length of the first driving member 210a is greater than that of the second driving member 210b. The first driving member 210a includes a tension spring that provides a first material ejection driving force, and the second driving member 210b includes a compression spring that provides a second material ejection driving force. The first material ejection driving force is a driving force in the upward direction, and the second material ejection driving force is a driving force in the downward direction. To separate the product 300 from the upper die 10, when the punch 110 rises to a preset height position, the pulling force generated by the tension spring at this time needs to meet the following requirements: the pulling force F generated by the tension spring 拉 is greater than the elastic force F generated by the compression spring 压 and the sum of the gravity G1 of the first material ejecting member 220a. The pulling force generated by the tension spring meeting the above requirements can cause the punch 110 to separate from the product 300.

[0035] Please refer to Figure 6 , Figure 6 is a schematic view of the product 300 and the stamping die not separated provided by an embodiment of the present utility model. As an implementation manner, the upper die 10 includes an upper die body 120 connected to the punch 110. The upper die body 120 is connected to the first material ejecting member 220a through the first driving member 210a to drive the first material ejecting member 220a to approach the second material ejecting member 220b.

[0036] Please refer to again Figure 3, as an implementation, the driving component 210 includes a blanking connecting member 210c. The upper die body 120 is connected to the first stripping member 220a through the first driving member 210a and the blanking connecting member 210c in sequence. The blanking connecting member 210c includes a blanking screw, and the blanking screw can improve the connection strength between the first driving member 210a and the first stripping member 220a, and improve the connection strength and reliability of the internal structure of the stamping die.

[0037] Please refer to Figure 5 , Figure 5 is a schematic diagram of the first stripping member 220a and the second stripping member 220b provided by an embodiment of the present invention. As an implementation, both the first stripping member 220a and the second stripping member 220b are hollow structures in the middle, and the punch 110 can pass through the hollow structure. Four first connection holes are spaced on the first stripping member 220a, and four blanking connecting members 210c are provided. The lower end of the blanking connecting member 210c is connected to the four first connection holes, and the upper end of the blanking connecting member 210c is connected to the first driving member 210a. Further, at least four second connection holes are spaced on the first stripping member 220a. The lower end of the second driving member 210b is connected to the second connection holes of the first stripping member 220a, and the lower end of the second driving member 210b is connected to the lower part of the first stripping member 220a, avoiding connection detachment, thereby improving the connection reliability between the first stripping member 220a and the second stripping member 220b.

[0038] Please refer to together Figure 4 and Figure 5 , as an implementation, the lower die includes a base 240 and a bracket 230 connected to the base 240. The second stripping member 220b is fixedly connected to the bracket 230. Specifically, the second stripping member 220b and the bracket 230 are provided with mutually matching screw connection holes, and the second stripping member 220b is fixedly arranged on the bracket 230 by passing screws or other fasteners through the screw connection holes, thereby improving the connection reliability between the second stripping member 220b and the bracket 230.

[0039] The second object of the present invention is to propose a processing device, including the stamping die according to any one of the above embodiments. The processing device further includes a manipulator and a power source. The power source can drive the upper die 10 to move up and down. The working principle of the processing device is as follows:

[0040] Please refer to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of the product 300 provided by an embodiment of the present invention not separated from the stamping die. Figure 7It is a schematic diagram of the separation of the product provided by the embodiment of the present utility model from the stamping die. The power source drives the upper die 10 and the punch 110 into the concave die to stretch out the product 300, and then the power source drives the product 300 to move upward. During the upward movement, the product 300 will contact the first stripping member 220a. Since the position of the second stripping member 220b is fixed, the second driving member 210b, that is, the compression spring, disposed between the first stripping member 220a and the second stripping member 220b, will be gradually compressed until it is completely compressed. During this process, the first stripping member 220a will gradually press against the second stripping member 220b. The upper die 10 continues to move upward with the punch 110 until the upper die 10 rises to a preset height position. The first stripping member 220a no longer moves upward. At this time, the upper part of the product 300 presses against the first stripping member 220a, and the first stripping member 220a presses against the second stripping member 220b. The second stripping member 220b is fixedly disposed on the lower die. At this time, the punch 110 continues to move upward, and the punch 110 and the product 300 are gradually separated. At this time, the manipulator starts to move to clamp the product 300.

[0041] Further, when the elastic force generated by the compression spring, that is, the second stripping driving force F 压 and the sum of the gravity G2 of the second stripping member 220b are greater than the frictional force f clamped by the manipulator, the product 300 will be pushed downward by a certain distance by the compression spring and the first stripping member 220a. After the upper die 10 continues to rise, the tension spring starts to pull the unloading screw. When the tension of the tension spring F 拉 is greater than the elastic force F 压 generated by the compression spring and the sum of the gravity G1 of the first stripping member 220a, the first stripping member 220a will be lifted upward, so that the upper port part of the product 300 is separated from the first stripping member 220a. Then the robotic arm (not shown in the figure) moves horizontally to transfer the position of the product 300. Specifically, it can be viewed Figure 7 , thus completing the separation of the product 300 from the upper die 10. In the solution of the present application, the following requirements are imposed on the power of the driving assembly 210: the tension F 拉 of the tension spring > the elastic force F 压 of the compression spring + the gravity G1 of the first stripping member 220a > the frictional force f between the manipulator and the product 300.

[0042] The solution of the present utility model avoids the product 300 from being scratched and deformed during the stripping process and the handling process of the manipulator by setting the first driving member 210a, the second driving member 210b, the first stripping member 220a, and the second stripping member 220b. At the same time, it avoids the product 300 staying in the stamping die, reduces the risk of insufficient stripping of the product 300, stabilizes the production process of the product 300, reduces the defective rate of the production of the product 300, and improves the production efficiency of the product 300.

[0043] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element present at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or it can also be indirectly connected to the other element through an intermediate element.

[0044] In addition, in the present utility model, the descriptions involving "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the technical features indicated. Thus, the features defined with "first" and "second" can explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0045] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made using the description of the specification and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
