Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, and particularly discloses an in-mold transmission mechanism for micro-punching parts. Background Art

[0002] In the metalworking industry, the production of micro-stamped parts typically involves multiple steps. First, a metal strip blank is punched through a stamping machine to form a blank. These blanks then undergo a secondary stamping process to be further processed into the final product. For example, in the production of a three-layer Ag / C1020 / Fe composite metal strip, it is first formed into a cylindrical blank with a diameter of φ3.0, and then the surface is stamped with protrusions or other features.

[0003] The existing production process faces several major challenges. First, due to the need for multiple stamping operations, production efficiency is relatively low. After each stamping operation, the production line must be stopped to collect and transport the blanks, which increases production time and reduces efficiency. Second, this multiple stamping method takes up a large amount of production space. The process of collecting and transporting blanks requires additional equipment and space, which not only increases the complexity of the factory layout but also increases production costs. Therefore, further improvement is needed. Utility Model Content

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] This embodiment discloses a micro stamping part in-mold transmission mechanism, referring to Figure 1-6 It includes a mold, a punching machine, a feeding belt 3, a blanking punch 44, a blanking insert 5, a forming punch 8, a forming insert 9 and a feeding assembly.

[0037] The mold includes an upper mold 1 and a lower mold 2. The upper mold 1 is driven to rise and fall by the punching equipment, and the lower mold 2 is supported on the base platform of the punching equipment. The upper mold 1 and the lower mold 2 are molds with multiple cavities, so that the feed belt 3 and feeding components and other components can be accommodated in the mold cavity when the mold is closed. The specific position and shape are not described in detail.

[0038] The feeding belt 3 is used to convey the material belt 3 to the mold. The feeding belt 3 can be driven by a motor roller. The feeding belt 3 is hollow in design and can be used for unloading the blank 200 after stamping.

[0039] The blanking punch 4 and the blanking insert 5 are provided under the upper die 1, and the blanking insert 5 is provided on the lower die 2. The blanking punch 4 and the blanking insert 5 are arranged opposite each other, and the feeding belt 3 is extended between the blanking punch 4 and the blanking insert 5. The blanking punch 4 and the blanking insert 5 are used to punch the blank strip 100 into the blank 200. Preferably, a spring pin is provided in the blanking punch 4 to help the blank 200 fall smoothly. In addition, preferably, a cutter is provided under the upper die 1, and the cutter is located on one side of the blanking punch 4. The cutter is used to cut the edge material strip left by the blanking punch 4 into small pieces. The lower die 2 is provided with an edge material hole 7, and a blow pin 6 is provided on one side of the end of the feeding belt 3. The blow pin 6 is used to blow the edge material toward the edge material hole 7 and discharge the edge material from the edge material hole 7.

[0040] The forming punch 8 and the forming insert 9 are arranged under the upper mold 1 and on one side of the conveying direction of the feeding belt 3 of the blanking punch 4. The forming insert 9 is arranged on the lower mold 2. The forming punch 8 and the forming insert 9 are arranged opposite to each other.

[0041] The feed assembly includes a first beveled wedge 10, a first slider 11, a first elastic member 12, and a feed plate 13. The first beveled wedge 10 is disposed below the upper mold 1, and the first slider 11 is slidably disposed on the lower mold 2 and connected to the first elastic member 12. The first slider 11 is provided with a first inclined surface that cooperates with the first beveled wedge 10. Under the push of the first beveled wedge 10 and the action of the first elastic member 12, the first slider 11 can slide back and forth on the lower mold 2 along the conveying direction of the feed belt 3. The feed plate 13 is connected to the first slider 11 and can extend to the molding insert 9. Preferably, the lower mold 2 is provided with two guide plates 14 extending along the conveying direction of the feed belt 3. The two guide plates 14 are located on both sides of the first slider 11, which play a guiding role in ensuring that the first slider can slide back and forth along the conveying direction of the feed belt 3 without deviation.

[0042] Specifically, the blanking inlet 5 is provided with a cavity for accommodating stacked blanks 200. The bottom of the blanking inlet 5 is provided with an opening for the feeding plate 13 to extend into. The opening connects the cavity to the top surface of the lower mold 2. The thickness of the feeding plate 13 is less than or equal to the thickness of a single blank 200. The feeding plate 13 pushes out the blanks 200 stacked on the bottom of the blanking inlet 5. In this way, the blanking inlet 5 can store a certain number of blanks 200 for blanking, so that when the blanking window gap of the blank belt 100 is replenished, there are also stored blanks 200 for stamping and forming operations. In addition, the top surface height of the forming inlet 9 is lower than the bottom surface height of the blank 200 at the bottom of the blanking inlet 5. The feeding plate 13 is provided with a blanking hole for accommodating a single blank 200. The blank 200 falls onto the forming inlet 9 through the blanking hole. In this way, the process of transporting the blanks 200 by the feeding plate 13 is smoother.

[0043] When the mold is closed, the upper mold 1 drives the first inclined wedge 10 to descend and contact the first slider 11. The first slider 11 is pushed to slide and drives the feed plate 13 to move toward the blanking input 5. The feed plate 13 pushes the blank 200 out of the blanking input 5. The blank 200 is pushed onto the forming input 9 and is punched into a product by the forming punch 8; when the mold is opened, the upper mold 1 drives the first inclined wedge 10 to rise and leave the first slider 11. The first elastic member 12 pulls the first slider 11 to slide, and the feed plate 13 returns to its original position. In this way, the two processes of simultaneous stamping and stamping in the same mold are realized.

[0044] As a preferred solution, the micro-stamping part in-mold conveying mechanism also includes a calibration component, which is arranged on one side of the forming inlet 9. The feed plate 13 pushes the blank 200 to the side of the forming inlet 9. The calibration component is used to clamp the blank 200 and push it forward along the direction of the feed belt 3 to the forming inlet 9. By adding the calibration component, even if the blank 200 is pushed out of the blanking inlet 5 at high speed by the feed plate 13 and slightly slips due to inertia, it can be calibrated to the position directly below the forming punch 8 under the clamping and pushing of the calibration component, thereby further accelerating the stamping operation speed and improving production efficiency while ensuring product quality. Of course, in other embodiments, if there is no requirement for the stamping speed, the calibration component may not be provided, but the pushing end position of the feed plate 13 may be matched and set directly below the forming punch 8, which can also achieve simultaneous stamping and forming in the same mold.

[0045] Specifically, the calibration assembly includes a second beveled wedge 15, a second slider 16, a second elastic member 17, and a clamping block 18. Two of each of the second beveled wedge 15, the second slider 16, the second elastic member 17, and the clamping block 18 are symmetrically arranged. The second beveled wedge 15 is positioned below the upper mold 1, and the second slider 16 is slidably positioned on the lower mold 2 and connected to the second elastic member 17. The second slider 16 is provided with a second inclined surface that cooperates with the second beveled wedge 15. Driven by the second beveled wedge 15 and the action of the second elastic member 17, the second slider 16 can slide back and forth on the lower mold 2 along the conveying direction of the feed belt 3. The clamping block 18 is positioned on the second slider 16. The two clamping blocks 18 are arranged opposite each other in a direction perpendicular to the feed belt 3. The two clamping blocks 18 are used to place the blanks 200 pushed out from the feed plate 13. When the mold is closed, the upper mold 1 drives the second inclined wedge 15 to descend and contact the second slider 16. The second slider 16 is pushed to slide and drives the clamping block 18 to move. The clamping block 18 pushes the blank 200 on the lower mold 2 along the conveying direction of the feed belt 3 to the forming input 9; when the mold is opened, the upper mold 1 drives the second inclined wedge 15 to rise and leave the second slider 16. The second elastic member 17 pulls the second slider 16 to slide, and the clamping block 18 returns to its original position.

[0046] As a preferred embodiment, the calibration assembly further includes a third beveled wedge 19, a third slider 20, and a third elastic member 21. Two third beveled wedges 19, two third sliders 20, and two third elastic members 21 are provided, each symmetrically arranged. The third beveled wedge 19 is provided below the upper mold 1. The third slider 20 is slidably mounted on the second slider 16 and connected to the third elastic member 21. The third slider 20 is provided with a third inclined surface that cooperates with the third beveled wedge 19. The clamping block 18 is fixed to the second slider 16 by the third slider 20. The third slider 20 is pushed by the third beveled wedge 19 and the third elastic member 21, thereby driving the two clamping blocks 18 to move back and forth on the second slider 16, moving them closer or further apart. During the downward movement of the upper mold 1, the second beveled wedge 15 first contacts the second slider 16, followed by the third beveled wedge 19 and the third slider 20, and finally the first beveled wedge 10 and the first slider 11. When the mold is closed, the clamping block 18 pushes the blank 200 on the lower mold 2 along the conveying direction of the feed belt 3 to the forming insert 9, and the third inclined wedge 19 is driven by the upper mold 1 to descend and contact the third slider 20. The third slider 20 is pushed to slide and drive the clamping block 18 away from the blank 200. When the mold is opened, the upper mold 1 drives the third inclined wedge 19 to rise and leave the third slider 20. The third elastic member 21 pulls the third slider 20 to slide, and the clamping block 18 returns to its original position. By adopting the above design, the third inclined wedge 19 drives the clamping block 18 to leave the blank 200 by a certain distance before the forming punch 8 punches the blank 200. For some products whose outer contours will expand to a certain extent during stamping, the clamping block 18 will not hinder the expansion of the blank 200, which not only avoids damage to the clamping block 18, but also ensures the smooth operation of stamping.

[0047] The specific action process of the in-mold transfer mechanism for fine stamping parts in this solution is as follows:

[0048] 1. The punch press's feed belt 3 feeds the Ag / C1020 / Fe three-layer composite material into the mold. The blanking punch 4 and blanking insert 5 punch out the three-layer composite sheet into a cylindrical blank 200. The blank 200 falls sequentially on the bottom of the punching insert. When the mold closes, the product's edge material is cut off by the cutter and blown into the adjacent edge material hole 7 by the blow pin 6. The edge material is then discharged from the bottom of the mold.

[0049] 2. The product blanks 200 are lined up in the blanking insert 5. The bottom blank 200 falls into the circular blanking hole of the feed plate 13. The mold is opened. As the upper mold 1 moves upward, the first inclined wedge 10 will be disconnected from the first slider 11. The first slider 11 will feed the material together with the feed plate 13 under the action of the first elastic member 12 until the material is fed to the specified position. At this time, the upper mold 1 moves to the top dead center of the punch press, completing the feeding of the blank 200.

[0050] 3. After the blank 200 is delivered to the designated position, it falls into the cavity formed by the surface of the forming insert 9 and the two clamping blocks 18. At this time, the punch press drives the upper die 1 to continue to move downward. The second wedge 15 moves downward with the upper die 1 and gradually begins to contact the second slider 16 and starts to move toward the product forming position until it moves into place.

[0051] 4. At this time, the third inclined wedge 19 will push the clamping blocks 18 on both sides back and make way. As the upper die 1 continues to move downward, the forming punch 8 of the upper die 1 begins to contact the blank 200. When the die moves to the bottom dead center, the product blank 200 is formed under the action of the downward pressure.

[0052] 5. At this time, the first inclined wedge 10 will push the first slider 11 and the feed plate 13 back together until the mold reaches the bottom dead center and the feed plate 13 retreats into place;

[0053] 6. The upper mold 1 will then rise. At this time, the first oblique wedge 10, the second oblique wedge 15 and the third oblique wedge 19 begin to rise. The third oblique wedge 19 rises, causing the clamping blocks 18 on both sides to begin to reset under the action of the third elastic member 21. At the same time, the second oblique wedge 15 rises, causing the second slider 16 to bring the clamping blocks 18 to reset under the action of the second elastic member 17. The upper mold 1 continues to move upward until the reset is completed. At this time, the first oblique wedge 10 continues to rise, and the first slider 11 will feed the material together with the feeding plate 13 under the action of the first elastic member 12 until the material is fed to the specified position. The upper mold 1 reaches the top dead center and completes feeding again. The reciprocating cycle is repeated to continuously form multiple products.
