Description

Technical Field

[0001] This utility model relates to a sheet metal stamping and drawing die, and in particular to a sheet metal stamping and drawing die used in the field of sheet metal processing. Background Technology

[0002] Sheet metal stamping and drawing dies are a commonly used piece of equipment for processing workpieces. They are core tools in metal plastic forming processes, and their main functions are to control material flow and forming accuracy: through structural designs such as draw beads, the die can precisely adjust the flow resistance of the sheet metal to prevent wrinkling or tearing; enhance the rigidity of parts and reduce defects: the drawing process intensifies the plastic deformation of the sheet metal, effectively reducing springback and improving the rigidity of the formed parts; and optimize process parameters and die life: the die reduces wear on the blank holder surface and extends the die's service life through the synergistic effect of blank holder force and draw beads.

[0003] The existing sheet metal stamping and drawing dies are cumbersome and time-consuming to eject the workpiece after processing, which makes it inconvenient for personnel to remove the processed workpiece and thus hinders the processing of the workpiece. Utility Model Content

[0004] The technical problem to be solved by this utility model is that, in the use of existing sheet metal stamping and drawing dies, the operation steps for ejecting the workpiece from the die after processing are cumbersome and time-consuming, which makes it inconvenient for personnel to remove the processed workpiece.

[0005] To solve the above problems, this utility model provides a sheet metal stamping and drawing die, including a lower die, the bottom of which is fixedly connected to a base; A pair of circular grooves are provided on the inner bottom wall of the base, and a plug-in block is movably inserted into the circular groove. A spring is fixedly connected between the plug-in block and the circular groove. The top of a pair of plug-in blocks is fixedly connected to the same lifting plate, the top of the lifting plate is fixedly connected to a connecting plate, the top of the connecting plate is fixedly connected to a plurality of symmetrically distributed connecting blocks, and the top of the connecting blocks is fixedly connected to a sealing block. The base has a pair of adjustment slots, and a telescopic rod is movably inserted into the adjustment slots. A push-pull plate is fixedly connected to one end of the telescopic rod near the lifting plate.

[0006] As a further improvement of this application, in the initial state, the sealing block is movably inserted inside the lower mold, and the inner bottom wall of the lower mold is flush with the top of the sealing block.

[0007] As a further improvement of this application, the bottom of the lifting plate abuts against the inner bottom wall of the base, and there is a gap between the top of the connecting plate and the bottom of the lower mold.

[0008] As a further improvement of this application, a sleeve ring is fixedly sleeved on the telescopic rod, and a spring is fixedly connected between the sleeve ring and the inner side wall of the base.

[0009] As a further improvement of this application, the end of the telescopic rod away from the push-pull plate passes through the base and extends out of the base to the outside.

[0010] As another improvement of this application, a fixing sleeve is fixedly connected to the side of the lower mold, and a limiting rod is movably inserted inside the fixing sleeve. The same horizontal plate is fixedly connected to the side of the pair of telescopic rods away from the push-pull plate, and a connecting pipe is fixedly connected to the side of the horizontal plate away from the telescopic rods.

[0011] As a further improvement to this application, the surface of the limiting rod is coated with a magnetic coating, and a metal ring that is magnetically attracted to the magnetic coating is fixedly connected to the inner wall of the fixing sleeve.

[0012] This application has the following beneficial effects when used: 1. Manually push the telescopic rod to move the push-pull plate toward the lifting plate. When the chamfered side of the push-pull plate abuts against the lifting plate, continue pushing the push-pull plate. The push-pull plate will push the lifting plate upward. As the push-pull plate moves continuously, the lifting plate will slide on top of the push-pull plate and gradually rise. As the lifting plate rises, it will push the connecting plate, connecting block, and sealing block upward together. Thus, the workpiece in the lower mold will be pushed upward by the sealing block, thereby causing the top of the workpiece to be removed from the lower mold. Finally, the personnel can remove the workpiece from the lower mold. When using this application, the operation steps for ejecting the processed workpiece are relatively simple and time-saving, thus facilitating the personnel to quickly remove the processed workpiece and greatly improving the convenience of personnel processing workpieces.

[0013] 2. When in use, move the push-pull plate so that the workpiece extends a certain length from the lower mold. Then, move the limiting bar down to separate the metal ring from the magnetic coating until the bottom end of the limiting bar is inserted into the fixed sleeve. This limits the horizontal plate and the push-pull plate, improves the stability of the push-pull plate under the lifting plate, prevents it from moving away from the lifting plate, and ensures the smooth progress of the material handling process.

Metal ring. Detailed Implementation

[0016] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0017] First implementation method: Figure 1-4 A sheet metal stamping and drawing die is shown, including a lower die 1, and a base 2 is fixedly connected to the bottom of the lower die 1; A pair of circular grooves 3 are provided on the inner bottom wall of the base 2. A plug-in block 4 is movably inserted into the circular groove 3. A spring 5 is fixedly connected between the plug-in block 4 and the circular groove 3. The top ends of a pair of plug-in blocks 4 are fixedly connected to the same lifting plate 6, the top of the lifting plate 6 is fixedly connected to a connecting plate 7, the top of the connecting plate 7 is fixedly connected to a plurality of symmetrically distributed connecting blocks 8, and the top of the connecting block 8 is fixedly connected to a sealing block 9. The base 2 has a pair of adjustment slots, and a telescopic rod 10 is movably inserted into the adjustment slots. A push-pull plate 11 is fixedly connected to one end of the telescopic rod 10 near the lifting plate 6.

[0018] In the initial state, the sealing block 9 is movably inserted inside the lower mold 1, and the inner bottom wall of the lower mold 1 is flush with the top of the sealing block 9.

[0019] The bottom of the lifting plate 6 abuts against the inner bottom wall of the base 2, and there is a gap between the top of the connecting plate 7 and the bottom of the lower mold 1.

[0020] A connecting ring 12 is fixedly sleeved on the telescopic rod 10. A spring 13 is fixedly connected between the connecting ring 12 and the inner wall of the base 2. When the telescopic rod 10 is moved to push the push-pull plate 11 to move together towards the lifting plate 6, the telescopic rod 10 will drive the connecting ring 12 to move together and stretch the spring 13. When the external force applied to the telescopic rod 10 is removed, the telescopic rod 10 and the push-pull plate 11 will be reset under the action of the elastic force of the spring 13.

[0021] The end of the telescopic rod 10 away from the push-pull plate 11 passes through the base 2 and extends out of the base 2 to the outside.

[0022] This solution can be implemented in the following way: after the workpiece is processed in the lower mold 1, the telescopic rod 10 can be manually pushed to push the push-pull plate 11 towards the lifting plate 6. When the chamfered side of the push-pull plate 11 abuts against the lifting plate 6, the push-pull plate 11 is pushed further and will push the lifting plate 6 upward. As the push-pull plate 11 moves continuously, the lifting plate 6 will slide on the top of the push-pull plate 11 and gradually rise. As the lifting plate 6 rises, it will push the connecting plate 7, connecting block 8 and sealing block 9 to move upward together. As a result, the workpiece in the lower mold 1 will be pushed upward by the sealing block 9, so that the top of the workpiece is moved out of the lower mold 1. Finally, the personnel can take the workpiece out of the lower mold 1.

[0023] In summary, when using this application, the operation steps for ejecting the processed workpiece are relatively simple and time-saving, thus facilitating the quick removal of the processed workpiece by personnel and greatly improving the convenience of personnel processing workpieces.

[0024] Second implementation method: This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below: Figure 4-5 The lower mold 1 is shown to be fixedly connected to a fixed sleeve 14 on its side. A limiting rod 15 is movably inserted into the fixed sleeve 14. A pair of telescopic rods 10 are fixedly connected to the same horizontal plate 16 on the side away from the push-pull plate 11. A connecting pipe 17 is fixedly connected to the side of the horizontal plate 16 away from the telescopic rods 10.

[0025] The surface of the limiting rod 15 is coated with a magnetic coating 18, and a metal ring 19 that is magnetically attracted to the magnetic coating 18 is fixedly connected to the inner wall of the fixing sleeve 14.

[0026] This solution allows for the following operation: when the push-pull plate 11 is moved, the workpiece extends a certain length from the lower mold 1, and then the limiting rod 15 is moved down to separate the metal ring 19 from the magnetic coating 18 until the bottom end of the limiting rod 15 is inserted into the fixed sleeve 14. This limits the horizontal plate 16 and the push-pull plate 11, improving the stability of the push-pull plate 11 below the lifting plate 6 and preventing it from moving down from the lifting plate 6, thus ensuring the smooth progress of the material handling process.
