[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping.

[0017] The method of using the precision stamping die for the production of mechanical parts includes the following steps:

[0018] Step 1: Fix the sheet to be punched, and the hydraulic cylinder drives the punching cylinder at the bottom to move downward. The punching cylinder moves downward and drives the pressing piece to move toward one end close to the lower punching die groove. At this time, the punching cylinder drives the pressing piece to move downward. The pressing piece moves downward and is squeezed with the pressing telescopic rod just above the processing platform. The top of the pressing telescopic rod is squeezed and drives the moving block at one end of the linkage rod to move along the fixed groove toward one end close to the lower punching die groove. At this time, the moving block drives the fixed arc piece at one end of the fixed telescopic rod to be squeezed with the edge of the punching sheet;

[0019] Step 2: Punch and shear the sheet to be punched. When the punching upper die and the sheet to be punched are punched, the punching cylinder drives the extrusion column and the extrusion inclined block to produce extrusion. The extrusion column is squeezed by the extrusion inclined block and drives the clamping block to slide into the inside of the punching cylinder. At this time, the extrusion column drives the clamping block to disengage from the clamping groove. The hydraulic cylinder continues to drive the sliding plate to slide downward along the inside of the punching cylinder. The sliding plate drives several shearing columns at the bottom to slide downward. At this time, the shearing column shears the sheet to be punched downward;

[0020] Step 3: Push out the stamped parts. When the stamping cylinder drives the stamping upper die to move downward, the stamping upper die drives the telescopic rod to move downward. When the pushing head at the bottom of the telescopic rod is squeezed with the plate, the telescopic rod is squeezed and shrinks along the stamping upper die toward the inside of the stamping cylinder. When the extrusion column drives the clamping block to slide inward along the sliding groove, the clamping block drives the sliding frame at one end of the linkage rod to slide upward, and the sliding frame drives several telescopic rods to slide upward. This arrangement is conducive to reducing the extrusion force between the pushing head and the surface of the stamping plate, thereby avoiding the pushing head from damaging the stamping plate. This arrangement is conducive to improving the stamping quality of the mechanical parts.

[0021] Step 4: Remove waste. When the shear column shears the stamped sheet downward, the shear column discharges the sheared sheet waste through the discharge port at the bottom of the reserved hole. When the sheet waste sticks to the bottom of the shear column, the shear column can continue to slide downward along the reserved hole. The shear column slides downward and is squeezed by the clearing block on the linkage rod three. At this time, the shear column slides downward and exceeds the clearing block. When the shear column slides upward to reset, the end of the clearing block close to the shear column scrapes off the sheet waste stuck to the bottom of the shear column.

[0022] The present invention has the following beneficial effects:

[0023] (1) The present invention sets a stamping and shearing mechanism. When the hydraulic cylinder moves downward, the hydraulic cylinder drives the stamping cylinder to move downward, and the stamping cylinder drives the clamping plate to move downward toward one end of the stamping die groove. When the stamping upper die and the sheet to be stamped are stamped, the stamping cylinder drives the extrusion column and the extrusion bevel block to produce extrusion. The extrusion column is squeezed by the extrusion bevel block and drives the clamping block to slide toward the inside of the stamping cylinder. At this time, the extrusion column drives the clamping block to disengage from the clamping groove. The hydraulic cylinder continues to drive the sliding plate to slide downward along the inside of the stamping cylinder. The sliding plate drives several shearing columns at the bottom to slide downward. At this time, the shearing column shears the sheet to be stamped downward. This arrangement is conducive to shearing the stamped sheet after the stamping step is completed. This arrangement is conducive to avoiding the simultaneous stamping and shearing of the sheet, ensuring that the shearing of the sheet is not affected by the stamping of the sheet, thereby ensuring the quality of part processing.

[0024] (2) According to the present invention, when the precision stamping die is used, the sheet to be stamped is first placed in the lower stamping die groove just above the processing platform. At this time, the hydraulic cylinder is started, and the hydraulic cylinder drives the stamping cylinder at the bottom to move downward. The stamping cylinder moves downward and drives the clamping plate to move toward one end close to the lower stamping die groove. At this time, the stamping cylinder drives the clamping plate to move downward. The clamping plate moves downward and is pressed against the pressing telescopic rod just above the processing platform. The top of the pressing telescopic rod is squeezed and drives the moving block at one end of the linkage rod to move along the fixed groove toward the end close to the lower stamping die groove. One end moves, and at this time the moving block drives the fixed arc piece at one end of the fixed telescopic rod to squeeze the edge of the stamping plate. Under the squeezing action of several fixed arc pieces, the plate to be stamped is fixed in the center of the lower stamping die groove. On the one hand, this arrangement is beneficial to fix the plate to be stamped inside the lower stamping die groove, thereby avoiding the phenomenon of misalignment of the stamping plate during stamping; on the other hand, several fixed arc pieces squeeze the edge of the plate to be stamped at the same time, which is beneficial to align the plate to be stamped directly below the stamping upper die, thereby ensuring the accuracy of the stamping parts.

[0025] (3) The present invention sets a pushing mechanism. When the stamping cylinder drives the stamping upper die to move downward, the stamping upper die drives the telescopic rod to move downward. When the pushing head at the bottom of the telescopic rod is squeezed with the plate, the telescopic rod is squeezed and shrinks along the stamping upper die toward the inside of the stamping cylinder. When the extrusion column drives the clamping block to slide inward along the sliding groove, the clamping block drives the sliding frame at one end of the linkage rod to slide upward, and the sliding frame drives a plurality of telescopic rods to slide upward. This arrangement is conducive to reducing the extrusion force between the pushing head and the surface of the stamping plate, thereby avoiding the pushing head from damaging the stamping plate. This arrangement is conducive to improving the stamping quality of the mechanical parts. When the stamping is completed, the hydraulic cylinder drives the stamping upper die at the bottom of the stamping cylinder to move upward. At this time, under the elastic force of the pressure spring and the extrusion spring, the pushing head pushes the mechanical parts stuck to the stamping upper die downward and separates them from the bottom of the stamping upper die. This arrangement is conducive to avoiding the parts from sticking to the bottom of the stamping upper die.

[0026] (4) The present invention provides a cleaning mechanism. When the shear column shears the stamped sheet downward, the shear column discharges the sheared sheet waste through the discharge port at the bottom of the reserved hole. When the sheet waste sticks to the bottom of the shear column, the shear column can continue to slide downward along the reserved hole. The shear column slides downward and is squeezed by the cleaning block on the linkage rod three. At this time, the shear column slides downward and exceeds the cleaning block. When the shear column slides upward to reset, the cleaning block close to the end of the shear column scrapes off the sheet waste stuck to the bottom of the shear column. This arrangement is conducive to quickly discharging the sheet waste at the bottom of the shear column, ensuring that the shear column can continuously process different stamped sheets, thereby improving the working efficiency of the device.

The function of this mechanism is that when the precision stamping die is used, the plate to be stamped is first placed into the lower stamping die groove 15 just above the processing platform 1, and the hydraulic cylinder 14 is started at this time. The hydraulic cylinder 14 drives the stamping cylinder 201 at the bottom to move downward, and the stamping cylinder 201 moves downward to drive the clamping plate 203 to move toward the end close to the lower stamping die groove 15. At this time, the stamping cylinder 201 drives the clamping plate 203 to move downward, and the clamping plate 203 moves downward. The top of the pressing telescopic rod 209 is squeezed to drive the moving block 205 at one end of the linkage rod 211 to move along the fixed groove 204 to one end close to the lower stamping die groove 15.

Under the squeezing action of several fixed arc pieces 207, the plate to be stamped is fixed in the center of the lower stamping die groove 15. On the one hand, this arrangement is conducive to fixing the plate to be stamped inside the lower stamping die groove 15, thereby avoiding the phenomenon of misalignment of the stamping plate during stamping; on the other hand, several fixed arc pieces 207 squeeze the edge of the plate to be stamped at the same time, which is conducive to aligning the plate to be stamped directly below the stamping upper die 202, thereby ensuring the accuracy of the stamping parts.

[0047] A stamping shearing mechanism 3 is arranged inside the stamping upper die 202, and the stamping shearing mechanism 3 includes a sliding plate 301 slidably connected to the inner wall of the stamping upper die 202, the top of the sliding plate 301 is fixedly connected to the bottom of the hydraulic cylinder 14, and a plurality of shearing columns 302 are fixedly connected to the bottom of the sliding plate 301, and a plurality of sliding grooves 303 are opened on the side wall of the stamping cylinder 201.

At this time, under the elastic force of the pressure spring 308 and the extrusion spring 403, the push head 402 pushes the mechanical parts stuck to the stamping upper die 202 downward and separates them from the bottom of the stamping upper die 202. This arrangement is conducive to preventing parts from sticking to the bottom of the stamping upper die 202; by setting Cleaning mechanism 5, when the shear column 302 shears the stamped sheet downward, the shear column 302 discharges the sheared sheet waste through the discharge port 502 at the bottom of the reserved hole 501, and when the sheet waste sticks to the bottom of the shear column 302, the shear column 302 can continue to slide downward along the reserved hole 501, and the shear column 302 slides downward and is squeezed by the cleaning block 508 on the linkage rod 3 509. At this time, the shear column 302 slides downward and exceeds the cleaning block 508.

[0053] The method of using the precision stamping die for the production of mechanical parts includes the following steps:

[0054] Step 1: Fix the sheet to be punched, the hydraulic cylinder 14 drives the punching cylinder 201 at the bottom to move downward, the punching cylinder 201 moves downward and drives the pressing piece 203 to move toward one end close to the lower punching die groove 15, at this time, the punching cylinder 201 drives the pressing piece 203 to move downward, the pressing piece 203 moves downward and is pressed against the pressing telescopic rod 209 just above the processing platform 1, the top of the pressing telescopic rod 209 is pressed and drives the moving block 205 at one end of the linkage rod 211 to move along the fixed groove 204 toward one end close to the lower punching die groove 15, at this time, the moving block 205 drives the fixed arc piece 207 at one end of the fixed telescopic rod 206 to be pressed against the edge of the punching sheet;

[0055] Step 2: Punching and shearing the sheet to be punched. When the punching upper die 202 and the sheet to be punched are punched, the punching cylinder 201 drives the extrusion column 304 and the extrusion inclined block 311 to produce extrusion. The extrusion column 304 is squeezed by the extrusion inclined block 311 and drives the clamping block 306 to slide into the inside of the punching cylinder 201. At this time, the extrusion column 304 drives the clamping block 306 to disengage from the clamping groove 305. The hydraulic cylinder 14 continues to drive the sliding plate 301 downward to slide downward along the inside of the punching cylinder 201. The sliding plate 301 drives the several shearing columns 302 at the bottom to slide downward. At this time, the shearing columns 302 shear the sheet to be punched downward;

[0056] Step 3: Push out the stamped parts. When the stamping cylinder 201 drives the stamping upper die 202 to move downward, the stamping upper die 202 drives the telescopic rod 401 to move downward. When the pushing head 402 at the bottom of the telescopic rod 401 is pressed against the plate, the telescopic rod 401 is pressed and shrinks along the stamping upper die 202 toward the inside of the stamping cylinder 201. When the extrusion column 304 drives the clamping block 306 to slide inward along the sliding groove 303, the clamping block 306 drives the sliding frame 309 at one end of the linkage rod 2 310 to slide upward. The sliding frame 309 drives a plurality of telescopic rods 401 to slide upward. This arrangement is conducive to reducing the extrusion force between the pushing head 402 and the surface of the stamping plate, thereby preventing the pushing head 402 from damaging the stamping plate. This arrangement is conducive to improving the stamping quality of the mechanical parts.

[0057] Step 4: Remove waste. When the shear column 302 shears the stamped sheet downward, the shear column 302 discharges the sheared sheet waste through the discharge port 502 at the bottom of the reserved hole 501. When the sheet waste sticks to the bottom of the shear column 302, the shear column 302 can continue to slide downward along the reserved hole 501. The shear column 302 slides downward and is squeezed by the clearing block 508 on the linkage rod 3 509. At this time, the shear column 302 slides downward and exceeds the clearing block 508. When the shear column 302 slides upward to reset, the clearing block 508 close to the end of the shear column 302 scrapes off the sheet waste stuck to the bottom of the shear column 302.
