Description

Technical Field

[0001] This utility model relates to the field of stamping machinery technology, specifically a stamping device that can be quickly replaced. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. In real life, many parts of everyday items are manufactured using stamping machinery. For example, many accessories for switches and sockets, cups, cabinets, plates, computer cases, and even missiles and airplanes are produced using stamping presses and dies.

[0003] Currently, existing quick-change stamping devices typically use auxiliary equipment to drive a connecting structure, connecting the stamping head to the device. However, these replacement structures often rely on auxiliary equipment, which is prone to problems such as circuit breaks, aging, or malfunctions, making replacement difficult. Furthermore, disassembly requires power outages or readjustment, leading to energy waste and reduced efficiency, resulting in poor ease of replacement. Additionally, in existing stamping dies, after the upper die presses against the lower die to form the material, the workpiece often remains inside the lower die cavity, making it difficult to remove and reducing production efficiency, thus hindering material removal.

[0026] Specifically, the fixed end of the hydraulic telescopic rod 13 is connected to the hydraulic pump and other hydraulic transmission structures through oil pipes. Multiple slide grooves 4 are provided on the connecting seat 1. In order to adapt to molds of different sizes, a connecting plate 6 is provided on each side of the lower mold 3. The support bolts 7 support downwards and lift the slider 18 upwards.

[0027] Please refer to Figure 1 to Figure 3 The support bolt 7 passes through the connecting plate 6 and the slider 18. The slider 18 is T-shaped and fits tightly with the groove 4.

[0028] Specifically, the support bolt 7 is located in the middle of the connecting plate 6, and the support bolt 7 passes through the slider 18 in the middle.

[0029] Please refer to Figure 1 to Figure 3 The lower part of the connecting plate 6 is attached to the connecting seat 1, the moving block of the lower mold 3 is the same size as the slider 18, and the lower mold 3 is located on the upper part of the connecting seat 1.

[0030] Specifically, the slider 18 is in contact with the moving block of the lower mold 3, and the end of the slide groove 4 away from the support frame 14 passes through the connecting seat 1.

[0031] Please refer to Figure 1. Figure 3 , Figure 4 A limiting plate 11 is fixedly connected to one side of the fixing block 19. One side of the limiting plate 11 is connected to the buckle 10 of the connecting block 12. The inner side of the limiting plate 11 is in contact with the connecting block 12.

[0032] Specifically, the limiting plate 11 is connected to the upper mold 15. The size of the upper mold 15 is larger than that of the fixing block 19. The buckle 10 is inserted into both sides of the limiting plate 11 to provide partial traction for the upper mold 15.

[0033] Please refer to Figure 1. Figure 3 , Figure 4 The upper mold 15 and the lower mold 3 are positioned correspondingly. The cross-section of the connecting block 12 is T-shaped. The buckle 10 consists of a fixing rod, a support spring, and a limiting block.

[0034] Specifically, the upper mold 15 is combined with the lower mold 3, and the front of the limiting block is chamfered. The limiting block is snapped into the outside of the limiting plate (11) by the elastic force of the support spring. When disassembling, pressing the limiting block to compress the support spring will disengage it.

[0035] Please see Figure 2 , Figures 5 to 6 A support spring is placed inside the insertion hole 17. The upper part of the support spring supports the connecting rod 16. The upper part of the lower mold 3 is fixedly connected to the limit post 9. The upper part of the limit post 9 is sleeved with the upper mold 15. The support frame 2 is sleeved on multiple limit posts 9.

[0036] Specifically, the upper part of the lower mold 3 is provided with a groove that matches the support frame 2, the upper part of the support frame 2 is in contact with the edge of the material, the edge of the support frame 2 is provided with a connecting hole, and the limiting post 9 is inserted into the connecting hole.

[0037] In use, the moving block of the lower mold 3 is slid into the corresponding groove 4, and then the slider 18 at the bottom of the connecting plate 6 is slid into the groove 4. When the lower mold 3 is connected to the connecting seat 1, a set of fixing structures is first slid in, so that there are a set of fixing structures on both sides of the lower mold 3. The connecting plate 6 is then attached to the lower mold 3. The support bolt 7 is then rotated, and the support bolt 7 supports the groove 4 downwards, thereby indirectly driving the slider 18 upwards. The upper part of the slider 18 supports the upper part of the groove 4, thereby fixing the connecting plate 6 and clamping the lower mold 3. Only one bolt is needed for easy disassembly and installation. Through the design of the groove 4, slider 18, support bolt 7 and connecting plate 6, The upper mold 15 is fixed in place, and the upper fixing block 19 of the upper mold 15 is slid into the connecting block 12. The upper mold 15 is pulled by the T-shaped fixing block 19, while the limiting plate 11 is attached to the connecting block 12. The buckle 10 is inserted into both sides of the limiting plate 11 to connect the fixing block 19, the limiting plate 11 and the connecting block 12. The fixing rod of the buckle 10 provides part of the pulling force on the upper mold 15. Through the cooperation of the connecting block 12, the fixing block 19, the limiting plate 11 and the buckle 10, the upper mold 15 can be quickly disassembled and assembled during use, so as to achieve the purpose of short mold replacement time and strong replacement convenience.

[0038] The material is placed on the lower mold 3. Through an external control structure, the external hydraulic pump is activated, drawing in hydraulic oil and delivering it through oil pipes to the hydraulic telescopic rod 13. This pushes the upper mold 15 downwards, causing it to press the material and form it. The upper mold 15 is then moved back to its original position, with the limiting post 9 aligning it with the lower mold 3. After the material is formed, the support frame 2 lifts the material. The limiting post 9 and connecting rod 16 limit the support frame 2, preventing it from detaching from the upper part of the lower mold 3. The connecting rod 16 serves to limit the position of the support frame 2. When the material is lifted upwards, the upper mold 15 moves upwards and is supported by the support spring pressed by the connecting rod 16, thus lifting the connecting rod 16 upwards. The support frame 2 moves upwards along with the limiting post 9, lifting the material. Through the coordinated arrangement of the connecting rod 16, support frame 2, support post 5, connecting plate 6, and insertion hole 17, the material can be lifted during use, thereby achieving the purpose of quickly removing the material and facilitating its removal.
