Description

Technical Field

[0001] This invention relates to the field of hardware processing technology, and in particular to a stamping device for hardware processing. Background Technology

[0002] Hardware parts refer to metal products obtained through processing. Hardware parts come in various shapes. In order to ensure processing quality and speed, stamping equipment is needed to assist in production. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in a mold and deform it, thereby obtaining product parts with certain shapes, sizes and properties.

[0003] Chinese patent document CN113118282B discloses a sheet metal stamping device, including a support base 1, a fixed plate 2 on the support base 1, a motor 3 on one side of the fixed plate 2, a first rotating shaft 4 connected to the extended end of the motor 3, the first rotating shaft 4 passing through the fixed plate 2 and having a first rotating wheel 5 at its end, a first locking block 6 fixed on the first rotating shaft 4, and a first connecting shaft 7 on the first locking block 6; a second rotating shaft 8 is mounted on the fixed plate 2 via a bearing, a second rotating wheel 9 is mounted on the second rotating shaft 8, the second rotating wheel 9 meshing with the first rotating wheel 5, a second locking block 10 fixed to the end of the second rotating shaft 8, and a second connecting shaft 11 on the second locking block 10. The above document can stably stamp sheet metal, ensuring stamping quality.

[0004] The above-mentioned documents still have the following shortcomings in implementation:

[0005] Although the aforementioned patent documents can stamp the sheet metal during implementation, they only have the effect of fixing the sheet metal and lack structures related to feeding and unloading. They require manual or mechanical feeding and unloading of each sheet individually, resulting in a low degree of automation. Summary of the Invention

[0006] The main objective of this invention is to provide a stamping device for processing hardware parts, which can effectively solve the problems mentioned above.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A stamping device for processing hardware parts includes a lower support, an upper support mounted on the top of the lower support, hydraulic cylinders mounted on the left and right sides of the top of the upper support, upper molds mounted on the bottom of the piston rods of the two hydraulic cylinders via bolts, raw material bins for holding sheet-shaped hardware raw materials mounted on the front and rear sides of the upper support, a rotatable moving mechanism mounted on the top of the lower support, a plurality of evenly distributed lower mold structures mounted in a ring on the moving mechanism, lifting mechanisms mounted between the left and rear sides and between the front and right sides of the lower support, and a pop-out mechanism mounted on the lower side of the vertical portion of the upper support.

[0009] Preferably, the outer side of the top of the lower support has a boss.

[0010] Preferably, the moving mechanism includes a support tray rotating on the top of the boss, a gear, and a servo motor installed below the gear. An external gear ring is installed at the bottom of the support tray. The servo motor is used to drive the gear. The gear meshes with the external gear ring. The support tray is hollow and sleeved on the outside of the upper support. Two energy storage plates are installed on the inner side of the top of the support tray. The top of the support tray has several mounting grooves.

[0011] Preferably, an L-shaped support plate is installed on the outer side of the L-shaped support plate, and an arc-shaped push plate is installed on the top of the vertical part of the L-shaped support plate.

[0012] Preferably, two L-shaped connecting plates are installed diagonally at the bottom of the tray, and each of the two L-shaped connecting plates has a lifting wheel at its bottom.

[0013] Preferably, the pop-out mechanism includes two arc-shaped connecting plates 1, and an arc-shaped connecting plate 2 is provided at both the head and tail of the two arc-shaped connecting plates 1. An elastic lever is installed on the outer side of each of the two arc-shaped connecting plates 2, and an auxiliary elastic support piece is provided between each elastic lever and the arc-shaped connecting plate 1 on the same side. Several connecting rods fixed to the outer side of the upper support are installed inside the two arc-shaped connecting plates 1.

[0014] Preferably, the lower mold structure includes a housing, which is bolted to the inner cavity of the mounting slot. A limiting ring I for improving stamping stability is installed on the top of the housing. A through slot parallel to the long side of the housing is opened at the bottom of the housing. A limiting ring II is installed in the middle of the inner side of the housing. Several guide rods slide on the limiting ring II. The tops of the several guide rods jointly support the lower mold I. The several guide rods and the lower mold I are fixed together by suction cups. A spring is provided between the bottom of the several guide rods and the limiting ring II. The several springs are evenly distributed in the inner cavities of the two through slots.

[0015] Preferably, the lifting mechanism includes two L-shaped support rods, both of which slide on the vertical part of the lower support. The top of the two L-shaped support rods is provided with a tray, and an arc-shaped adjusting block that works with the lifting wheel is installed on the inner side of the bottom of the tray. When the arc-shaped adjusting block passes the lifting wheel, the lifting wheel can lift the arc-shaped adjusting block to drive the guide rod to push the stamped hardware out of the inner cavity of the housing.

[0016] Preferably, the two elastic levers are located above the two lifting wheels respectively.

[0017] Preferably, the raw material bin has a discharge trough on the side away from the upper support. The bottom of the discharge trough is provided with an arc-shaped support plate parallel to the long side of the raw material bin. The two short sides of the surface of the discharge trough have discharge troughs. The arc-shaped push plate is arc-shaped and can enter the inner cavity of the discharge trough through the two discharge troughs to push out the metal sheet raw material.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This device, through the coordinated design of the raw material hopper, the arc-shaped push plate of the moving mechanism, the lifting mechanism, and the ejection mechanism, realizes a cyclical process of "automatic feeding of metal sheets - stamping processing - automatic unloading of finished products". Specifically, the arc-shaped push plate can automatically push the metal sheet raw material to the lower mold structure through the discharge chute of the raw material hopper to complete the automatic feeding. After stamping, the lifting mechanism lifts the finished product, and the ejection mechanism ejects the finished product from the lower mold to complete the automatic unloading. No additional manual or mechanical intervention is required, which significantly improves the level of automation.

[0020] 2. This device uses an arc-shaped pusher plate to push out the bottom metal sheet and let it fall into the inner cavity of the outer shell. The remaining metal sheets in the inner cavity of the raw material hopper will automatically fill the gap under the action of gravity.

[0021] 3. This device uses a designed servo motor to drive the tray to rotate. With the wedge-shaped engagement of the arc-shaped adjusting block and the lifting wheel, it automatically completes the lifting of the tray and the upward movement of the guide rod. Without manual or additional mechanical intervention, the stamped finished hardware parts can be completely pushed out of the inner cavity of the outer shell. This effectively solves the problem of low automation caused by reliance on manual or separate mechanical material feeding in the background technology, reduces manual operation costs, and improves processing continuity.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] This device uses sheet metal. Before stamping, the complete sheet metal needs to be divided into long strips using existing metal sheet cutting equipment, and then the stamping operation is performed using this device.

[0036] Example 1, as Figure 1 and Figure 2 As shown, a stamping device for processing hardware parts includes a lower support 1, an upper support 2 installed on the top of the lower support 1, hydraulic cylinders 3 installed on the left and right sides of the top of the upper support 2, upper molds 8 installed at the bottom of the piston rods of the two hydraulic cylinders 3 by means of bolt removal, raw material bins 4 for holding sheet-shaped hardware raw materials installed on the front and rear sides of the upper support 2, a rotatable moving mechanism 6 installed on the top of the lower support 1, several evenly distributed lower mold structures 7 are installed in a ring on the moving mechanism 6, lifting mechanisms 5 are installed between the left and rear and between the front and right sides of the lower support 1, and a pop-out mechanism 9 is installed on the lower side of the vertical part of the upper support 2.

[0037] In this embodiment, the cut metal sheets are stacked in the inner cavity of the raw material silo 4 in sequence. Then, the moving mechanism 6 is activated. By rotating the moving mechanism 6, the metal sheets in the inner cavity of the raw material silo 4 are released from the bottom of the raw material silo 4 to the lower mold structure 7 in sequence. When the metal sheets move to the bottom of the upper mold 8, the hydraulic cylinder 3 is activated to press the metal sheets through the upper mold 8. With the cooperation between the upper mold structure 7 and the lower mold structure 7, the metal parts are stamped and produced.

[0038] Subsequently, as the moving mechanism 6 rotates, the lower mold structure 7 is moved above the lifting mechanism 5. During this process, the moving mechanism 6 stores force on the ejection mechanism 9, and the lifting mechanism 5 starts to drive the lower mold structure 7 to run, pushing the stamped finished hardware upward. As the moving mechanism 6 rotates, the storage process on the ejection mechanism 9 is released. At this time, the lifting mechanism 5 also pushes the finished hardware completely out of the lower mold structure 7, and ejects the finished hardware through the ejection mechanism 9.

[0039] Subsequently, the moving mechanism 6 continues to rotate, squeezing the ejector mechanism 9 again, causing the ejector mechanism 9 to continue to accumulate power. The lower mold structure 7 moves to the bottom of another raw material bin 4, pushing out the metal sheets stacked inside the raw material bin 4, and continuing to stamp the metal sheets through another hydraulic cylinder 3 and the upper mold 8.

[0040] Based on the above description, this embodiment can sequentially complete the cyclical process of metal sheet loading - metal sheet stamping - finished hardware ejection - metal sheet loading.

[0041] Specifically, to achieve the aforementioned material handling, the lower mold structure 7 is moved by dragging it. (See [reference needed]). Figure 3 and Figure 4In this embodiment, the lower support 1 has a boss on the outer side of the top, which is used to raise the height of the moving mechanism 6 so that the lower mold structure 7 can not interfere with the lower support 1 during operation, and ensure that the lower mold structure 7 can operate normally.

[0042] For further details, please refer to [link / reference]. Figure 3 and Figure 4 In this embodiment, the moving mechanism 6 includes a support tray 64 rotating on the top of the boss, a gear 62, and a servo motor 63 installed below the gear 62. An external gear ring 61 is installed at the bottom of the support tray 64. The servo motor 63 is used to drive the gear 62. The gear 62 meshes with the external gear ring 61. The support tray 64 is hollow and sleeved on the outer side of the upper support 2. Two energy storage plates 68 are installed on the inner side of the top of the support tray 64. The top of the support tray 64 has several mounting grooves 67.

[0043] Before implementing this example, the rotation angle of the servo motor 63 needs to be preset according to the number of lower mold structures 7 so that the servo motor 63 can rotate at the preset angle.

[0044] For example, in this case, there are 8 lower mold structures 7. In order to ensure that each lower mold structure 7 can be moved directly below the upper mold 8 and the raw material hopper 4, the pallet 64 rotates 45° each time, based on a 360° circle.

[0045] The servo motor 63 mentioned above is installed on the side of the lower support 1. The servo motor 63 drives the gear 62 to rotate, which in turn drives the external gear ring 61 to rotate at a specific angle.

[0046] Specifically, for the purpose of stamping the sheet metal in coordination with the upper die 8, please refer to... Figure 6 and Figure 7 The lower mold structure 7 includes a housing 71, which is bolted to the inner cavity of the mounting groove 67. A limiting ring 72 for improving stamping stability is installed on the top of the housing 71. A through groove 74 parallel to the long side of the housing 71 is opened at the bottom of the housing 71. A limiting ring 75 is installed in the middle of the inner side of the housing 71. Several guide rods 76 slide on the limiting ring 75. The tops of the several guide rods 76 jointly support the lower mold 73. The several guide rods 76 and the lower mold 73 are fixed together by suction cups. A spring 77 is provided at the bottom of the several guide rods 76 and between the limiting ring 75. The several springs 77 are evenly distributed in the inner cavities of the two through grooves 74.

[0047] The outer casing 71 described above is installed in the inner cavity of the mounting groove 67 by bolts, which facilitates the replacement of the outer casing 71.

[0048] In this embodiment, in the initial state, the top height of the lower mold 73 and the top height of the outer shell 71 are at the same level. The height of the limiting square ring 72 is higher than that of the lower mold 73 in the initial state. After the metal sheet is placed on the lower mold 73, the limiting square ring 72 can block the metal sheet to prevent the metal sheet from shifting during the rotation of the outer shell 71 with the support tray 64, thus ensuring the processing quality.

[0049] When the metal sheet is stamped by the upper die 8, the upper die 8 will push the lower die 73 downward. Under the guidance of the guide rod 76, the lower die 73 gradually moves to the top of the limiting ring 75. The limiting ring 75 supports the lower die 73, forcing the lower die 73 to stop moving downward. It cooperates with the upper die 8 to stamp the metal sheet into finished hardware parts. During the stamping process, several springs 77 are stretched and stored. After the stamping is completed, several springs 77 release their elasticity and push the lower die 73 back to the initial position.

[0050] In this case, the lower mold 73 is placed on top of several guide rods 76, and the two are in contact. During the movement of the lower mold 73, the guide rods 76 and the inner wall of the outer shell 71 jointly guide the lower mold 73, ensuring that the lower mold 73 can move downward normally horizontally.

[0051] Specifically, to ensure that the ejector mechanism 9 can eject the finished hardware parts, please refer to... Figure 8 and Figure 9 In this embodiment, two L-shaped connecting plates 65 are installed diagonally at the bottom of the support tray 64, and each of the two L-shaped connecting plates 65 has a lifting wheel 66 rotating at its bottom.

[0052] The lifting mechanism 5 includes two L-shaped support rods 51. Both L-shaped support rods 51 slide on the vertical part of the lower support 1. The top of the two L-shaped support rods 51 is provided with a tray 52. ​​An arc-shaped adjusting block 53 that works with the lifting wheel 66 is installed on the inner side of the bottom of the tray 52. ​​When the arc-shaped adjusting block 53 passes the lifting wheel 66, the lifting wheel 66 can lift the arc-shaped adjusting block 53 to drive the guide rod 76 to push the stamped hardware out of the inner cavity of the outer shell 71.

[0053] The process of rotating the pallet 64 to pick up materials is divided into two stages;

[0054] First stage: After stamping is completed, the upper mold 8 separates from the outer shell 71, and the lower mold 73 returns to its initial position. Then, the servo motor 63 drives the tray 64 to rotate counterclockwise from a top-down perspective. The head of the arc-shaped adjusting block 53 begins to contact the lifting wheel 66. Since the arc-shaped adjusting block 53 is an arc-shaped wedge, the horizontal height of the tray 52 will be gradually raised during the rotation of the lifting wheel 66, so that the tray 52 moves upward under the support of the L-shaped support rod 51. The tray 52 drags several guide rods 76 upward, completely pushing the finished hardware out of the inner cavity of the outer shell 71.

[0055] For further details, please refer to [link / reference]. Figure 4 and Figure 5 In this embodiment, the pop-out mechanism 9 includes two arc-shaped connecting plates 91. The head and tail of the two arc-shaped connecting plates 91 are both provided with arc-shaped connecting plates 92. Elastic paddles 93 are installed on the outer side of the two arc-shaped connecting plates 92. Each elastic paddle 93 and the arc-shaped connecting plate 91 on the same side are both provided with an auxiliary elastic support piece 94. Several connecting rods 95 fixed to the outer side of the upper support 2 are installed inside the two arc-shaped connecting plates 91.

[0056] The two flexible levers 93 are located above the two lifting wheels 66 respectively;

[0057] The elastic paddle 93 mentioned above is an elastic arc-shaped metal sheet. The auxiliary elastic support plate 94 supports the elastic paddle 93 and is also elastic. The auxiliary elastic support plate 94 can pop out instantly without the action of external force, ensuring that the elastic paddle 93 can generate sufficient elastic force.

[0058] The arc-shaped connecting plate 91 and the four connecting rods 95 mentioned above can fix the elastic lever 93 and the like to the outside of the upper support 2, ensuring the stability of the elastic lever 93 during the pop-out process.

[0059] The arc-shaped connecting plate 92 is used to provide space for the deformation of the elastic lever 93.

[0060] Second stage: After the finished hardware is fully lifted by the lifting wheel 66 and the arc-shaped adjusting block 53, as the support tray 64 rotates again, the elastic paddle 93 separates from the power storage plate 68. The elastic force generated by the pressing is released in the gap between the two power storage plates 68 and is released instantly, popping the finished hardware out of the lower mold 73, separating the finished hardware from the lower mold 73, and completing the automatic unloading step. As the support tray 64 drives the power storage plate 68 to rotate again, the power storage plate 68 squeezes the elastic paddle 93 again to continue storing the elastic force.

[0061] After the lifting wheel 66 and the arc-shaped adjusting block 53 separate, the pallet 52 returns to its initial position under the action of gravity, and the lower mold 73 also returns to its initial position.

[0062] Example 2: Based on Example 1, this example can automatically feed materials simultaneously.

[0063] Specifically, to achieve the aforementioned goal of automatic feeding, please refer to... Figure 10 and Figure 11 In this embodiment, an L-shaped support plate 681 is installed on the outside of the L-shaped support plate 681, and an arc-shaped push plate 682 is installed on the top of the vertical part of the L-shaped support plate 681.

[0064] For further details, please refer to [link / reference]. Figure 10 and Figure 11 In this embodiment, the side of the raw material silo 4 away from the upper support 2 is provided with a feeding trough 41. The bottom of the inner cavity of the feeding trough 41 is provided with an arc-shaped support plate 42 parallel to the long side of the raw material silo 4. The two short sides of the surface of the feeding trough 41 are provided with a discharge trough 43. The arc-shaped push plate 682 is arc-shaped and can enter the inner cavity of the feeding trough 41 through the two discharge troughs 43 and push out the metal sheet raw material.

[0065] The aforementioned feeding trough 41 not only facilitates the placement of metal sheets into the inner cavity of the raw material hopper 4, but also allows for easy observation of the number of metal sheets within the inner cavity of the raw material hopper 4.

[0066] The metal sheet inside the raw material silo 4 is supported by two arc-shaped support plates 42. The arc-shaped push plate 682 shuttles through the inner cavity of the two discharge troughs 43. The thickness of the arc-shaped push plate 682 is suitable for the thickness of common stamping plates, that is, the thickness of the arc-shaped push plate 682 cannot exceed the thickness of a metal sheet.

[0067] Since the power storage plate 68 rotates along an arc path, in order to ensure that the arc-shaped push plate 682 can pass smoothly through the inner cavity of the raw material bin 4, the arc-shaped push plate 682 needs to be set to an arc shape as well. Similarly, in order to ensure that the L-shaped support plate 681 does not interfere with the raw material bin 4, the L-shaped support plate 681 needs to pass between the raw material bin 4 and the outer shell 71.

[0068] After the arc-shaped pusher plate 682 pushes out the metal sheet at the bottom and it falls into the inner cavity of the outer shell 71, the remaining metal sheets in the inner cavity of the raw material bin 4 will automatically fill the gap under the action of gravity.

[0069] The entire implementation process of this plan is as follows:

[0070] 1. Preliminary preparations

[0071] The cut long metal strips are stacked in sequence in the feeding trough 41 of the raw material silo 4, and supported by the arc-shaped support plate 42.

[0072] 2. Automatic feeding

[0073] The servo motor 63 drives the gear 62 to rotate, which in turn drives the bearing tray 64 to rotate by meshing with the external gear ring 61.

[0074] The energy storage plate 68 on the support plate 64 rotates with it, driving the L-shaped support plate 681 and the arc-shaped push plate 682 to move.

[0075] The arc-shaped push plate 682 enters the discharge trough 41 through the discharge trough 43 of the raw material bin 4, pushing out the bottom metal sheet so that it falls into the outer shell 71 of the lower mold structure 7.

[0076] The remaining metal sheets in raw material silo 4 are automatically replaced by gravity, waiting for the next feeding.

[0077] 3. Stamping process

[0078] The support tray 64 drives the lower mold structure 7 carrying the metal sheet to rotate to directly below the upper mold 8;

[0079] Hydraulic cylinder 3 drives upper mold 8 to move downwards to stamp the metal sheet;

[0080] During the stamping process, the lower die 73 moves under the guidance of the guide rod 76, compresses the spring 77, and is supported and limited by the limiting square ring 75;

[0081] After the upper die 8 and the lower die 73 cooperate to complete the stamping, the spring 77 returns to its original position, driving the lower die 73 back to its initial position.

[0082] The limiting square ring 72 prevents the metal sheet from shifting throughout the process, ensuring stamping stability.

[0083] 4. Automatic feeding

[0084] The support tray 64 continues to rotate, moving the stamped finished hardware parts above the lifting mechanism 5;

[0085] 5. Lifting stage: The lifting wheel 66 at the bottom of the support tray 64 contacts the arc-shaped adjusting block 53. Because the arc-shaped adjusting block 53 is an arc wedge, the lifting wheel 66 gradually lifts the tray 52. ​​The L-shaped support rod 51 drives the guide rod 76 to move upward, and the finished product is completely pushed out of the outer shell 71.

[0086] 6. Pop-out stage: The support tray 64 rotates to separate the power storage plate 68 from the elastic tab 93 of the pop-out mechanism 9. The elastic tab 93 releases its elastic force under the action of the auxiliary elastic support plate 94, popping the finished product out of the lower mold 73.

[0087] After the lifting wheel 66 separates from the arc-shaped adjusting block 53, the tray 52 resets under the action of gravity, and the lower mold 73 also returns to its initial position, waiting for the next cycle.

[0088] 7. Cyclic operation

[0089] The pallet 64 rotates continuously at a preset angle, repeating the "loading-stamping-unloading" process to achieve continuous automated processing.
