Description

Technical Field

[0001] A die with fixed punching parts. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. With the improvement of my country's stamping technology, the use of stamping products has become more and more extensive, the manufacturing accuracy of the products has been greatly improved, and the degree of stamping automation has gradually increased.

[0003] For some specific products (such as auto parts), Fig. 9 The workpiece 10 shown is a bowl-shaped structure and needs to undergo multiple processing steps after stamping. Generally, a robot is used to remove the formed workpiece. With the existing mold structure, it is difficult to demold the workpiece after molding, and the position is prone to shifting after demolding. It is difficult for the robot to achieve fixed-point material picking when picking up materials, which affects the positioning of the workpiece during subsequent processing. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1 As shown, the mold with a fixed stamping component described in the utility model includes an upper mold 8 and a lower mold 2 that are correspondingly arranged. The middle part of the lower mold 2 extends upward to form an integrated forming mold 21. The bottom of the upper mold 8 is processed with a forming groove 81. The outer side of the forming mold 21 is evenly provided with a supporting platform 4 along the circumferential direction for placing a sheet 7 (see Figure 2 ), the lower part of the support platform 4 is connected to the gas spring 3, the gas spring 3 is built into the lower part of the lower mold 2, and the groove 22 is processed on the lower mold 2. After the gas spring 3 shrinks, the lower part of the support platform 4 moves into the groove 22. The distance between the support platform 4 and the outer wall of the forming mold 21 is less than the thickness of the sheet 7. The outer diameter of the lower part of the upper mold 8 matches the diameter of the sheet 7. The bottom edge of the upper mold 8 is evenly provided with a pressing block 9 along the circumferential direction (see Figure 3 ), the height difference between the bottom surface of the pressing block 9 and the bottom surface of the upper mold 8 is greater than the thickness of the sheet 7, the pressing block 9 is in an arc structure, the pressing block 9 and the supporting platform 4 are staggered, the two ends of the pressing block 9 extend to the upper edge of the adjacent supporting platform 4 respectively, and a limit block 41 is installed at the middle edge of the supporting platform 4. The pressing block 9 and the limit block 41 are staggered. A guide rod 5 is slidably provided at the center of the forming mold 21, and an upper positioning block 51 is provided on the upper part of the guide rod 5. The magnetic block 6 is embedded in the middle part of the positioning block 51. A positioning groove 24 is provided at the center of the upper part of the forming mold 21, and the upper positioning block 51 is built into the positioning groove 24. An inner cavity 23 is provided at the center of the lower mold 2, and the inner cavity 23 is connected with the positioning groove 24 through a guide hole 25. The lower part of the guide rod 5 passes through the guide hole 25 and then extends into the inner cavity 23. A lower end of the guide rod 5 is provided with a lower positioning block 52, and the lower mold 2 is installed on the lower workbench 1, and the lower part of the inner cavity 23 extends to the lower workbench 1.

[0026] In the device, the blank is placed on the stripping table and limited by a limit block. The flat blank is punched into a bowl-shaped workpiece through the cooperation of the upper die and the lower die, and a guide rod with a magnetic block is provided in the middle of the lower die for workpiece positioning. After stamping and forming, the workpiece is automatically oriented and demolded by the stripping table. The positioning is accurate, no additional power is required, the operation is efficient, and it is convenient to cooperate with subsequent feeding. A pressing block is provided at the lower edge of the upper die for pressing the stripping table down. The position of the pressing block avoids the blank to prevent the blank from being pressed and affecting the forming.

[0027] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0028] picture Figure 7-9 As shown, the sheet 7 before stamping is a circular flat plate structure, and the workpiece 10 after stamping is a bowl-shaped structure;

[0029] In actual production, the blank is placed on the support table, and the edge of the blank is limited by the limit block. At this time, the blank is located directly above the forming mold, the upper mold moves downward, and the two ends of the pressing block are respectively in contact with the adjacent support table. There is a certain gap between the blank and the bottom surface of the upper mold (see Figure 4 ), the upper die continues to move downward, at this time the gas spring contracts, the pressure block presses the support table downward, and the blank moves downward synchronously until the middle of the sheet contacts the upper surface of the forming die, and the magnetic block located on the upper part of the forming die is adsorbed and positioned with the sheet; as the upper die continues to move downward, when the height of the support table is lower than the upper surface of the forming die, the bottom surface of the upper die contacts the blank, and the forming grooves of the forming die and the upper die cooperate with each other to punch the sheet into a workpiece, and the lower part of the support table extends into the groove of the lower die (see Figure 5 ); After the workpiece is formed, the upper die moves up and resets. After the support table loses the downward pressure of the pressure block, it uses the gas spring to move up and reset. During the upward movement of the support table, the edge of the workpiece abuts against the edge of the support table, and the support table drives the workpiece to move up synchronously. At this time, the magnetic block on the upper part of the guide rod is still in an adsorption state with the workpiece, and the guide rod moves up as a whole with the workpiece (see Figure 6 ), due to the positioning effect of the magnetic block, the position of the workpiece after demoulding is unique, and the position of the manipulator is determined when picking up the material, which is convenient for directional picking up. When the workpiece is taken away, the guide rod slides down and resets under the action of its own gravity, and the next piece of material can be stamped.

[0030] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
