Stamping equipment for socket inserts

[0042] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following embodiments or drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0043] Such as figure 1 , 2 As shown, it includes an upper mold control module 1, an upper mold 2, a work table 3, a support 5, and a lower mold 7. The work table 3 is installed on the upper side of the support 5, and the upper side of the work table 3 has evenly distributed lower molds. 7; The upper die control module 1 is installed on the back side of the workbench 3, such as figure 1 , 10 As shown, a plurality of upper molds are uniformly installed on the upper mold control module 1, and the upper mold 2 installed on the upper mold control module 1 and the lower mold 7 on the upper side of the worktable 3 cooperate with each other to form a plurality of different Station, such as figure 1 , 17 As shown, the metal sheet 4 is transported on the upper side of the worktable 3 through the transmission mechanism, and is located on the upper side of the upper mold 2; it is characterized by: figure 1 , 2 As shown, the last one of the plurality of stations has an installation block 6 installed on the lower side of its corresponding workbench 3, such as image 3 As shown, one side of the mounting block 6 is provided with a square notch 8; the mounting block 6 is slidably mounted with a supporting slider 15; Figure 14 As shown, the lower mold 7 corresponding to the station is mounted on a swing plate 28, the swing plate 28 is rotatably mounted on one side of the square notch 8 through a mounting shaft 53, and the mounting shaft 53 slides with the support through a gear and a rack. Block 15 is connected in transmission; before the sliding up movement of the supporting slider 15 is completed, the swing plate 28 first swings to a horizontal state, after the sliding up movement of the supporting sliding block 15 is completed, the upper end of the supporting sliding block 15 and the lower end of the swing plate 28 are in contact and fit ; Through the design of gears and racks to ensure that the swing of the swing plate 28 is greater than 90 degrees, the preferred angle is between 100 and 120 degrees; this can ensure that after the swing plate 28 swings down, the stamping part 27 can be reliably gravity moved from the lower die 7 Disengagement; the support slider 15 supports the swing plate 28, so that most of the impact force received by the lower die 7 during the stamping process is absorbed by the support slider 15. The function of the swing plate 28 designed in the present invention is to make the stamping part 27 that is finally punched out on the swing plate 28 swing with the swing plate 28 during the downward swing of the swing plate 28, and then fall automatically by its own gravity to complete the discharge Process.

[0044] Such as Picture 11 , 12 As shown, a first telescopic structure 30 is installed on the lower side of the supporting slider 15 and a third spring 59 is provided in the first telescopic structure 30; a second rack 10 is installed on the first telescopic structure 30, such as Figure 4 As shown, a first rack 9 is installed on the upper mold 2 corresponding to the station, and the first rack 9 and the second rack 10 are connected by a second gear 31 and a third gear 32 through a variable speed transmission; Figure 5 , 11 As shown in 13, the inner side of the mounting block 6 is slidably mounted with a support block 16, which is connected to the second rack 10 through gears and racks; when the support slide 15 is moved up, it supports The block 16 starts to be driven to slide into the support slider 15 to support and limit the support slider 15. In the present invention, after the support slider 15 slides upward and comes into contact with the swinging plate 28 after being flattened, the support slider 15 stops sliding. At this time, the support square hole 29 opened on the support slider 15 exactly matches the support block 16; After the support slide 15 stops sliding upwards, the support block 16 is driven to start sliding, and slides into the support square hole 29 opened on the support slide 15, and finally the two ends of the support block 16 are opened by the mounting block 6. Supported by two limiting grooves 19, the support slide 15 is supported and limited by the support block 16; the impact force received by the support slide 15 during the stamping process is transmitted to the mounting block 6 through the support block 16, which improves the stability.

[0045] The reason for the design of the first telescopic structure 30 in the present invention is that the upper die 2 will drive the first rack 9 to move down during the downward movement, and the first rack 9 drives the second gear through the transmission of the second gear 31 and the third gear 32 The bar 10 moves up, and the second rack 10 moves up through the first telescopic structure 30 to drive the support slider 15 up. At the same time, when the second rack 10 moves up, the second rack 10 will drive the third rack 20 Move up, because the third rack 20 of the present invention did not mesh with the fourth gear 39 at the beginning; therefore, the support block 16 did not slide when the support slider 15 first moved up; when the support slider 15 After moving up to the limit state and contacting the swing plate 28 after swinging, it stops moving up. At this time, the third rack 20 just meshes with the fourth gear 39; at this time, the third rack 20 passes through the first gear 21 and the fourth gear. The transmission of 39 drives the support block 16 to slide, but because the support slide 15 has moved to the limit state, the upward movement is limited, so the second rack 10 moves upward at this time to compress the first telescopic structure 30; The second rack 10 interferes with the support slider 15 when it drives the support block 16 to slide; on the other hand, when the support slider 15 moves up to position, the existence of the first telescopic structure 30 can also ensure that the upper mold 2 continues to move down. Perform stamping.

[0046] In the stamping equipment designed by the present invention, in the first few stations, the metal sheet 4 is stamped into a specified shape. When passing through the last station, the metal sheet 4 completes the final stamping, and the final stamping is performed while the final stamping is completed. Finally, the punched parts 27 after punching are discharged; that is, the punching equipment designed in the present invention can combine the final punching process, punching process and discharge process in the last station, which improves the production effectiveness.

[0047] Such as Figure 4 , 12 , 13, the second gear 31 and the third gear 32 are coaxially mounted in the mounting block 6, the first rack 9 meshes with the third gear 32, and the second gear 31 meshes with the second rack 10; The diameter of the second gear 31 is greater than the diameter of the third gear 32.

[0048] The present invention changes the transmission ratio by designing the diameter of the second gear 31 to be greater than the diameter of the third gear 32, so that the upper die 2 can complete the final stamping process, punching process and discharge of the metal sheet 4 even when the upper die 2 moves down by a small amplitude. The process solves the situation of combining the final stamping process, punching process and nesting process in the case of small rising space mentioned in the background.

[0049] Such as Figure 7 As shown, the side of the square notch 8 opened on the mounting block 6 is provided with a shaft hole 25, and one end of the mounting shaft 53 is rotatably mounted in the shaft hole 25, as Figure 15 , 16 As shown, the outer circumference of the other end of the mounting shaft 53 is provided with two guide blocks 54 uniformly circumferentially; one end of the swing plate 28 has a mounting sleeve 56, and the outer circular surface of the mounting sleeve 56 has two evenly circumferentially opened There are two guide grooves 57, and the swing plate 28 is installed on the mounting shaft 53 through the cooperation of two guide grooves 57 and two guide blocks 54; a cylindrical rubber pad 55 is also installed between the mounting shaft 53 and the mounting sleeve 56. Through the cooperation of the guide block 54 and the guide groove 57, the mounting shaft 53 can drive the swing plate 28 to swing during the rotation; the designed rubber pad 55 can reduce the impact of the swing plate 28 on the mounting shaft 53 during the stamping process. And most of the impact force is transmitted to the supporting slider 15.

[0050] Such as Figure 8 , 9 As shown, the lower end surface of the square notch 8 opened on the mounting block 6 is provided with a fourth mounting slot 14; the support slider 15 is slidably mounted on the mounting block 6 through the fourth mounting slot 14, and supports the upper end of the slider 15 The fourth installation slot 14 is inserted into the square notch 8.

[0051] Such as Figure 4 , 12 As shown, one side of the fourth installation groove 14 is provided with a third installation groove 13; one side of the third installation groove 13 is provided with a second installation groove 12; the first rotating shaft 33 is rotatably installed in the second installation groove 12; The second gear 31 and the third gear 32 are fixedly mounted on both ends of the first rotating shaft 33; the upper end surface of the second mounting groove 12 is provided with a guide hole 26 passing through the upper side of the mounting block 6, and the first rack 9 The lower end of the first telescopic structure 30 passes through the guide hole 26 to mesh with the third gear 32; the upper end of the first telescopic structure 30 is fixedly installed on the lower side of the support slider 15, and the lower end of the first telescopic structure 30 is transversely installed with a first connecting strip 17, and A connecting bar 17 is located in the third mounting groove 13, and the lower end of the second rack 10 is fixedly mounted on the first connection. The movement of the second rack 10 drives the first telescopic structure 30 to move through the first connecting bar 17.

[0052] Such as Figure 7 As shown, one side of the fourth installation groove 14 is provided with a seventh installation groove 24, and one side of the seventh installation groove 24 is provided with a first installation groove 11; the end of the installation shaft 53 installed in the shaft hole 25 is located in the first In the installation slot 11; Figure 14 As shown, the fifth gear 41 is fixedly mounted on the end of the mounting shaft 53 in the seventh mounting slot 24, the sixth gear 44 is rotatably mounted in the seventh mounting slot 24 through the third rotating shaft 45, the sixth gear 44 and the fifth gear 41 meshing; the seventh gear 46 is rotatably mounted in the seventh mounting slot 24 through the fourth shaft 47, and the seventh gear 46 is meshed with the sixth gear 44; the eighth gear 48 is rotatably mounted in the seventh mounting slot 24 through the fifth shaft 49 Inside, the eighth gear 48 meshes with the seventh gear 46; the fourth rack 22 is mounted on the support slider 15 through the second connecting bar 23, and the fourth rack 22 meshes with the eighth gear 48; the second connecting bar 23 is located The fourth installation slot 14.

[0053] Such as Figure 14 As shown, a third telescopic structure 50 is installed between the fourth rack 22 and the second connecting bar 23, and a fourth spring 52 is provided in the third telescopic structure 50.

[0054] The reason for the design of the third telescopic structure 50 of the present invention is that when the support slider 15 moves up, the support slider 15 will drive the swing plate 28 to swing, and when the swing plate 28 swings to a horizontal state, the support slider 15 has not moved yet. At the limit state, the supporting slider 15 continues to move upward, the swing plate 28 stops swinging, and the fourth rack 22 stops moving; the second connecting bar 23 drives the third telescopic structure 50 to contract, and the fourth spring 52 compresses; After the process is completed, the upper mold 2 at the last station moves up, and the upper mold 2 moves up through the first rack 9, the second rack 10, the third gear 32, and the second gear 31 to drive the support slider 15 down. When the support slider 15 just starts to move down, the support slider 15 drives the second connecting bar 23 to move down. At this time, the originally compressed part of the fourth spring 52 starts to reset. When the fourth spring 52 returns to the initial drive pendulum The second connecting bar 23 starts to drive the third telescopic structure 50 to drive the fourth rack 22 to move down after the state of the plate 28 when it swings. At this time, there is a certain gap between the upper end of the support slider 15 and the lower end of the swing plate 28 The purpose of this design is to prevent the swing plate 28 from squeezing and interfering with the supporting slider 15 during the downward swing, which affects the structure operation.

[0055] Such as Figure 14 As shown, the above-mentioned clamping block 42 is fixedly installed in the seventh installation slot 24, the limiting block 43 is installed on the outer circular surface of the end of the mounting shaft 53 located in the seventh installation slot 24, and the limiting block 43 cooperates with the clamping block 42. Through the cooperation of the limiting block 43 and the clamping block 42, the swing plate 28 has a limiting effect after swinging to a horizontal state.

[0056] Such as Picture 12 As shown, the supporting sliding block 15 is provided with a supporting square opening; Figure 5 , 6 As shown, two limiting grooves 19 are opened on both sides of the fourth installation groove 14. Among the two limiting grooves 19, one side of the limiting groove 19 close to the first installation groove 11 is opened with the first installation groove 11 and The sixth installation groove 18 communicating with the second installation groove 12; Figure 5 , 13 As shown, one end of the guide rod 35 is fixedly mounted on the side surface of the second mounting groove 12, the support block 16 is slidably mounted on the guide rod 35, and the support block 16 and the support slide 15 are opened on the support square and the fourth The two limit grooves 19 opened on the mounting groove 14 are matched; the guide rod 35 plays a guiding and supporting role for the support block 16; a first spring 34 is installed between the support block 16 and the second mounting groove 12; a first spring 34 The function is to reset the support block 16; such as Figure 13 As shown, the lower side of the supporting block 16 has teeth; the second rotating shaft 38 is rotatably installed in the sixth mounting groove 18, the first gear 21 is fixedly installed at one end of the second rotating shaft 38, the first gear 21 and the supporting block The teeth on the 16 mesh; the fourth gear 39 is fixedly installed with the other end of the second shaft 38; the third rack 20 is installed on the second rack 10 through the third connecting bar 37; the third rack 20 and the fourth gear 39 is matched, the diameter of the first gear 21 is greater than the diameter of the fourth gear 39; the reason why the diameter of the first gear 21 is greater than the diameter of the fourth gear 39 in the present invention is that the third rack 20 in the present invention It is not meshed with the fourth gear 39; and the distance that the support block 16 needs to slide when supporting and limiting the support slider 15 is relatively large, so the present invention changes the transmission by the diameter of the first gear 21 and the fourth gear 39 In contrast, after the third rack 20 is meshed with the fourth gear 39, the distance that the third rack 20 can move upward can still enable the support block 16 to be completely inserted into the support square hole 29 opened on the support slider 15. The support slider 15 is supported and limited.

[0057] Such as Figure 13 As shown, a second telescopic structure 36 is installed between the third rack 20 and the third connecting bar 37, and the second telescopic structure 36 has a second spring 40 inside.

[0058] Before punching, the support block 16 needs to be fully inserted for effective limit. The purpose is to support the sliding block 15 during the punching process and the friction force on the support block 16 is relatively large. The support block 16 that is not fully inserted will not be able to continue to move. The effective limit makes the support block 16 easily damaged. The reason for the design of the second telescopic structure 36 in the present invention is that before punching, the upper die 2 passes through the first rack 9, the second rack 10, the third gear 32, the second gear 31, the third rack 20, and the second rack. A gear 21 and a fourth gear 39 drive the support block 16 to be inserted into the support slider 15 to limit the support slider 15, and then the upper die 2 continues to move down to continue punching the metal sheet 4. At this time, the second telescopic structure 36 stretches, avoids interference between the third rack 20 and the third connecting bar 37.

[0059] The lower mold 7 of the last station is detachably installed on the swing plate 28. It is convenient to change different lower molds 7 according to different needs.

[0060] The above-mentioned upper die 2 and lower die 7 have the functions of punching and punching, and the specific design may adopt the existing technology.

[0061] Specific work flow: When using the stamping equipment designed in the present invention, the metal sheet 4 is stamped into the specified shape after the first several stations are stamped. After the metal sheet 4 is moved to the last station, the last station The upper mold 2 moves down, and the upper mold 2 drives the first rack 9 to move down during the downward movement. The first rack 9 drives the second rack 10 to move up through the transmission of the second gear 31 and the third gear 32. The second rack 10 moves up through the first telescopic structure 30 to drive the support slider 15 to move up. At the same time, when the second rack 10 moves up, the second rack 10 will drive the third rack 20 to move up. The third rack 20 did not mesh with the fourth gear 39 at the beginning; therefore, the support block 16 did not slide when the support slider 15 first moved up; at the same time, the support slider 15 would pass through the second connecting bar 23 drives the fourth rack 22 to move. The fourth rack 22 moves to drive the eighth gear 48 to rotate. The eighth gear 48 rotates to drive the seventh gear 46 to rotate. The seventh gear 46 rotates to drive the sixth gear 44 to rotate. The sixth gear 44 rotates. The rotation drives the fifth gear 41 to rotate, the rotation of the fifth gear 41 drives the mounting shaft 53 to rotate, and the rotation of the mounting shaft 53 drives the swing plate 28 to swing upward.

[0062] When the swing plate 28 swings to the horizontal state, the support slider 15 has not moved to the limit state. At this time, the support slider 15 continues to move upward, the swing plate 28 stops swinging, and the fourth rack 22 stops moving; the second connecting bar 23 The third telescopic structure 50 is driven to contract, and the fourth spring 52 is compressed. When the support slider 15 moves up to the limit state and contacts the swing plate 28 after swinging, it stops moving up. At this time, the third rack 20 just meshes with the fourth gear 39; at this time, the third rack 20 passes through the first gear The transmission of 21 and the fourth gear 39 drives the support block 16 to slide, but because the support slide 15 has moved to the limit state, the upward movement is restricted, so the second rack 10 moves upward at this time to compress the first extension Structure 30.

[0063] When the support block 16 is driven to slide into the support square hole 29 opened on the support slider 15, and finally the two ends of the support block 16 are supported by the two limit grooves 19 opened on the mounting block 6, passing the support block 16 The support slider 15 is supported and limited. After that, the metal sheet 4 is transferred into place. After the metal sheet 4 is in place, the upper mold 2 punches the metal sheet 4, and the upper mold 2 punches the metal sheet 4 while punching.

[0064] After the punching is completed, the upper die 2 starts to move upward; the upper die 2 moves upward first through the first rack 9, the second rack 10, the third gear 32, the second gear 31, the third rack 20, and the first rack. The gear 21 and the fourth gear 39 drive the support block 16 away from the support slider 15, drive the support slider 15 to move down, and the support slider 15 drives the second connecting bar 23 to move down. At this time, the originally compressed part of the fourth spring 52 begins Reset, when the fourth spring 52 is reset to the state when the swing plate 28 is initially driven to swing, the second connecting bar 23 starts to drive the third telescopic structure 50 to drive the fourth rack 22 to move down, and the upper end of the support slider 15 is now supported There is a certain gap with the lower end of the swing plate 28. The fourth rack 22 moves down and drives the eighth gear 48 to rotate through the fourth rack 22. The eighth gear 48 rotates to drive the seventh gear 46 to rotate, and the seventh gear 46 to rotate. Rotation drives the sixth gear 44 to rotate. The sixth gear 44 rotates to drive the fifth gear 41 to rotate. The fifth gear 41 rotates to drive the mounting shaft 53 to rotate. The mounting shaft 53 rotates to drive the swing plate 28 to swing down, which makes the lower mold 7 move up. The stamping parts 27 of the dies fall under the action of its own gravity to complete the discharging process.
