A punching mechanism that facilitates die changing

Abstract

This utility model relates to the technical field of blanking mechanisms, specifically a blanking mechanism that facilitates mold replacement. It includes a base plate, with a bracket fixedly connected to the left side of the upper surface of the base plate. When installing the mold, the upper and lower molds are inserted into a card holder. As the molds enter the card holder, they compress a wedge-shaped locking block, causing the wedge-shaped locking block and sliding rod to move outwards, stretching the spring. Once the mold is fully inside the card holder, the wedge-shaped locking block is perfectly aligned with the slot. The spring then shortens, causing the wedge-shaped locking block to insert into the slot, locking the upper and lower molds and completing the quick installation. When mold replacement is needed, pushing the sliding plate moves it closer to the card holder. The sliding plate pushes a connecting plate, which in turn pushes a transmission rod. The transmission rod pushes a connecting frame away from the card holder, causing the wedge-shaped locking block to move out of the slot, releasing the mold from its locking position and allowing for easy removal. The mold installation process can then be repeated, saving time and effort.

[0002] Blanking is a basic process in stamping technology and is widely used in mass production processes in industries such as machinery manufacturing, electronics, automobiles, and hardware. Blanking mechanisms are commonly used equipment in machining, which mainly use dies to blank materials to obtain parts of the required shape and size.

[0003] In actual production, frequent mold changes are necessary to adapt to the production needs of different products. Existing mold replacement methods mostly involve directly fixing the upper and lower molds to the upper and lower mold bases respectively with bolts. This fixing method is time-consuming and labor-intensive; disassembling and installing multiple bolts requires a significant amount of time and manpower, severely impacting production efficiency. Furthermore, operators using tools for heavy tightening operations are prone to tool slippage or injuries. Therefore, how to achieve rapid, safe, and accurate mold replacement to improve production efficiency and safety is one of the problems that needs to be solved in the current use of blanking mechanisms. To address this, a blanking mechanism that facilitates mold replacement is proposed. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, when installing a mold, inserts the upper and lower molds into the card box respectively. During the mold's entry into the card box, it compresses the wedge-shaped locking block, causing the wedge-shaped locking block and the sliding rod to move outward, stretching the spring. When the mold is fully inside the card box, the wedge-shaped locking block is perfectly aligned with the slot. The spring then shortens, causing the wedge-shaped locking block to insert into the slot, locking the upper and lower molds and completing the quick installation. When mold replacement is needed, pushing the sliding plate moves it closer to the card box. The sliding plate pushes the connecting plate, which in turn pushes the transmission rod. The transmission rod pushes the connecting frame away from the card box, causing the wedge-shaped locking block to move out of the slot, releasing the mold from its lock and allowing for easy removal. The mold installation operation can then be repeated. This saves time and effort, allowing a single person to quickly disassemble and install the mold, enabling rapid, safe, and accurate mold replacement, thereby improving production efficiency and safety, and bringing convenience to the use of the punching mechanism.

[0023] Please see Figure 1-6This utility model provides a technical solution: a punching mechanism that facilitates mold replacement, including a base plate 1, a bracket 2 fixedly connected to the left side of the upper surface of the base plate 1, an electric cylinder 4 fixedly connected to the upper surface of the bracket 2, a lower plate 3 fixedly connected to the middle of the upper surface of the base plate 1, one end of the piston rod of the electric cylinder 4 passing through the upper surface of the bracket 2 and fixedly connected to an upper plate 5, and card boxes 6 fixedly connected to the upper surface of the lower plate 3 and the lower surface of the upper plate 5, respectively. An upper mold 7 and a lower mold 8 are respectively inserted into the inner sidewalls of the two card boxes 6, and slots 9 are provided on both sides of the outer sidewalls of the upper mold 7 and the lower mold 8. Both sides of the outer side wall of the card box 6 are provided with sliding grooves 10. The inner side wall of the sliding groove 10 is slidably connected to a sliding rod 11.

[0029] The working principle of this utility model is as follows: The fixing block 23 can be locked onto the punching worktable using the fixing hole 24 and external screws, preventing accidental movement of the punching mechanism. During mold installation, the upper mold 7 and lower mold 8 are inserted into the card box 6 respectively. As the mold enters the card box 6, it compresses the wedge-shaped locking block 12, causing the wedge-shaped locking block 12 and the sliding rod 11 to move outwards, stretching the spring 14. When the mold is fully inserted into the card box 6, the wedge-shaped locking block 12 is perfectly aligned with the card slot 9. The spring 14 then shortens, causing the wedge-shaped locking block 12 to insert into the card slot 9, locking the upper mold 7 and lower mold 8, thus completing the process.
