Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die which is convenient for replacing a stamping head. 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 it, thereby obtaining the desired parts.

[0003] Patent publication number "CN220112040U" discloses "a stamping die for stamping parts. The utility model can conveniently eject the formed stamping parts from the forming cavity through the mutual cooperation of the stripping plate, the damping rod, and the second compression spring, thereby realizing demolding. At the same time, it can also buffer the impact force generated during stamping, reducing the possibility of damage to the stamping parts and the stamping head. Specifically, during stamping, the cylinder drives the mounting seat to move downward, and the mounting seat drives the stamping head to stamp. The product enters the molding cavity for molding, and then the cylinder drives the stamping head to rise and reset. The second compression spring generates a reverse force to lift the stripping plate upward, and then the formed product is ejected. At the moment of stamping, the damping rod and the second compression spring contract to generate a reverse force for buffering. The mutual cooperation of the protective frame, the guide protrusion, the guide groove, and the first compression spring can conveniently protect the stamping area. Specifically, during stamping, the mounting seat presses down the protective frame, and the protective frame protects the stamping area. After the stamping, it can rise and reset, which increases safety and practicality.

The stamping mechanism 3 includes a connecting box 305, a push rod 306 and a sliding rod 311. The push rod 306 is slidably connected to the upper surface of the connecting box 305 and passes through the upper surface of the connecting box 305.

[0037] In this embodiment, the transport mechanism 2 can drive the rotating shaft 201 to rotate through the motor 203, so that the belt 202 rotates and drives the sliding box 204 and the stamping part to move, and the second electric telescopic rod 209 drives the rack 210 to move and mesh with the gear 212, so that the gear 212 drives the rotating rod 211 to rotate, and then the clamping plate 213 rotates and disengages from the belt 202. After the first electric telescopic rod 207 retracts and disengages from the inner wall surface of the base 1, the sliding box 204 can be removed from the device for replacement, and the stamping mechanism 3 can be pneumatically operated. The cylinder 302 drives the stamping block 304 to descend and extrude the stamping part to complete the stamping of the stamping part. After the slide bar 311 is pulled upward to make the slide bar 311 disengage from the push rod 306, the No. 2 spring 307 retracts and drives the push rod 306 to return to the inside of the connecting box 305.

[0041] In this embodiment, by starting the cylinder 302, the cylinder 302 drives the stamping block 304 to descend and extrude the stamping part to complete the stamping of the stamping part. After the slide bar 311 is pulled upward to make the slide bar 311 disengage from the push rod 306, the No. 2 spring 307 retracts and drives the push rod 306 to return to the inside of the connecting box 305. At the same time, the No. 3 spring 310 loses the force and rebounds to drive the telescopic rod 308 and the limit plate 309 to return to the initial position. After that, the slide bar 311 is released to make the No. 4 spring 312 drive the slide bar 211 to contact the limit plate 309. The stamping block 304 and the stamping head can be removed from the device for replacement.

[0042] Reference Figure 3 to Figure 4 In one aspect of this embodiment, a rotating shaft 201 is rotatably connected to both sides of the inner wall of the base 1, a belt 202 is slidably connected to the surface of the rotating shaft 201, a motor 203 is fixedly installed on one side of the inner wall of the base 1, and the output shaft of the motor 203 is fixedly connected to the rotating shaft 201.

[0045] A clamping plate 213 is fixedly mounted on the surface of the rotating rod 211 . A gear 212 is fixedly mounted on the surface of the rotating rod 211 . The gear 212 is meshed with the rack 210 .

[0046] In this embodiment, by starting the motor 203, the motor 203 drives the rotating shaft 201 to rotate, so that the belt 202 rotates and drives the sliding box 204 and the stamping part to move, and the No. 2 electric telescopic rod 209 is started so that the No. 2 electric telescopic rod 209 drives the rack 210 to move and engage with the gear 212 so that the gear 212 drives the rotating rod 211 to rotate and then the splint 213 rotates and disengages from the belt 202. After that, the No. 1 electric telescopic rod 207 is started so that the No. 1 electric telescopic rod 207 retracts and disengages from the inner wall surface of the base 1, and then the sliding box 204 can be removed from the device for replacement.

[0047] Working principle: When the device is used, the device should be placed in the designated position first, and then the stamping part is placed inside the sliding box 204, and then the motor 203 is started. The motor 203 drives the rotating shaft 201 to rotate, so that the belt 202 rotates and drives the sliding box 204 and the stamping part to move. Then the cylinder 302 is started, and the cylinder 302 drives the stamping block 304 to descend and extrude the stamping part to complete the stamping of the stamping part. When the stamping block 304 descends, it squeezes the connecting block 206 so that the connecting block 206 slides on the inner wall surface of the sliding box 204 and squeezes the No. 1 spring 205 so that the No. 1 spring 205 retracts and then rebounds to push out the material under the stamping. If the stamping head needs to be replaced, pull the sliding rod 311 upward to make the sliding rod 311 disengage from the push rod 306, and then the No. 2 spring 307 retracts and drives the push rod 306. When the connecting box 204 is in the state of being moved back to the inside of the connecting box 305, the No. 3 spring 310 loses the force and rebounds to drive the telescopic rod 308 and the limit plate 309 to return to the initial position, and then the sliding rod 311 is released to make the No. 4 spring 312 drive the sliding rod 211 to contact the limit plate 309, and the punching block 304 and the punching head can be removed from the device for replacement. If it is necessary to remove the connecting box 204 from the device, start the No. 2 electric telescopic rod 209 to make the No. 2 electric telescopic rod 209 drive the rack 210 to move and engage with the gear 212, so that the gear 212 drives the rotating rod 211 to rotate and then the splint 213 rotates and disengages from the belt 202. Then, start the No. 1 electric telescopic rod 207 to make the No. 1 electric telescopic rod 207 retract and disengage from the inner wall surface of the base 1, and then the sliding box 204 can be removed from the device for replacement.
