Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for metal products. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products).

[0003] However, in the existing technology, the upper and lower molds of common stamping dies are rigidly connected and fixed to the device body, which can only stamp metal products into products of fixed shape and specifications. The function is limited, and the mold parts are prone to wear over time, making disassembly and replacement inconvenient. Therefore, we propose a metal product stamping die. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1-5 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0025] like Figure 1-5 As shown, this utility model discloses a metal stamping die, including a base 1. A lower die 2 is mounted on the upper surface of the base 1 via a snap-fit ​​mechanism. A top plate 4 is fixedly mounted on the base 1 via a vertically arranged support column 3 at a corner. A connecting plate 5 is mounted on the top plate 4 via a lifting control mechanism. The lifting control mechanism includes an electric push rod 19 vertically fixedly mounted on the upper surface of the top plate 4. The free end of the electric push rod 19 movably passes through the top plate 4 and is fixedly connected to the connecting plate 5. A transition plate 6 is mounted on the connecting plate 5 via a buffer mechanism. An upper die 7 is horizontally arranged on the lower surface of the transition plate 6. Two movable connecting pieces 8 are vertically fixedly installed on the upper end face of the mold 7, passing through the adapter plate 6. A door-shaped mounting piece 9 is fixedly installed on the upper end face of the adapter plate 6. A force-bearing plate 10 is fixedly installed in the middle of the mounting piece 9. A pulling plate 11 is installed on the force-bearing plate 10 through an elastic clamping mechanism. An inverted T-shaped snap-fit ​​piece 12 is fixedly installed on the outer wall of the pulling plate 11. The snap-fit ​​piece 12 movably passes through the mounting piece 9 and the connecting pieces 8. By setting up a detachable lower mold 2 and an upper mold 7, different specifications of lower mold 2 and upper mold 7 can be replaced and installed, and metal products can be stamped and processed into different shapes, making it more functional.

[0026] Specifically, the locking mechanism includes two fixing blocks 13 fixedly installed on the upper surface of the base 1. The two fixing blocks 13 are symmetrically arranged and slide in cooperation with the outer side wall of the lower mold 2. The side wall of the fixing block 13 has a groove 14 opened laterally. The inner wall of the groove 14 is fixedly installed with a plug post 16 through a first spring 15 arranged laterally. The plug post 16 is movably embedded into the side wall of the lower mold 2. The plug post 16 is connected to a locking cancellation mechanism, which locks the lower mold 2 in place by the plug post 16, making the lower mold 2 detachable and replaceable. The locking cancellation mechanism includes a control rod 17 rotatably installed on the lower surface of the base 1. The control rod 17 is fixedly connected to the plug post 16 through a steel wire 18. The steel wire 18 movably passes through the fixing block 13 and the base 1. A knob is installed at the end of the control rod 17 for easy rotation. Rotating the control rod 17 allows the steel wire 18 to be wound onto the control rod 17, indirectly pulling the plug post 16 back into the groove 14 to cancel the locking and simplifies the operation.

[0027] More specifically, the buffer mechanism includes a limiting rod 20 vertically fixedly installed at the corner of the upper end face of the adapter plate 6. The limiting rod 20 movably passes through the connecting plate 5. The adapter plate 6 is fixedly connected to the connecting plate 5 through a second spring 21 movably sleeved on the limiting rod 20. The limiting rod 20 is set to work with the second spring 21 to buffer, making the contact between the upper mold 7 and the lower mold 2 more gentle and protecting the device components.

[0028] Furthermore, the elastic clamping mechanism is horizontally fixedly installed on the telescopic rod 22 on the outer wall of the force-bearing plate 10. The telescopic rod 22 is fixedly connected to the pulling plate 11. A third spring 23 is movably sleeved on the outer wall of the telescopic rod 22. The telescopic rod 22 provides an installation base for the third spring 23. The third spring 23 indirectly presses the snap-fit ​​member 12 to fix the connecting piece 8.

[0029] Furthermore, the connecting plate 5 and the adapter plate 6 are respectively movably sleeved on the outer wall of the support column 3, and the support column 3 limits the connection plate 5 and the adapter plate 6, making the up-and-down movement of the connection plate 5 and the adapter plate 6 more stable.

[0030] Working principle:

[0031] Pushing the two pull plates 11 against the force of the third spring 23 to move them towards the center, the pull plates 11 drive the snap-fit ​​piece 12 to move towards the center, and then insert the connecting piece 8 of the selected upper mold 7 into the adapter plate 6. Then, release the pull plates 11 to allow the third spring 23 to push the pull plates 11 back to their original position. The pull plates 11 push the snap-fit ​​piece 12 into the connecting piece 8, indirectly fixing the upper mold 7. Rotate the control lever 17 by the knob to pull the plug-in post 16 back into the groove 14 through the steel wire 18. Then, place the selected lower mold 7 on the base 1. Then, release the control lever 17 to allow the plug-in post 16 to return to its original position. The plug-in post 16 snaps and fixes the lower mold 7. Then, place the metal product in the lower mold 2. Control the electric push rod 19 to extend and indirectly drive the upper mold 2 to move downward. The upper mold 2 cooperates with the lower mold 7 to stamp the metal product into a fixed shape.
