Abstract
A punch plate trim waste ejection apparatus comprising: the blind hole of opening on the insert, the pressure spring of assembly in the blind hole bottom, the assembly in the blind hole top by the knock pin of spring top holding, through the big envelope of screw assembly at the blind hole opening part, the knock pin diameter be less than the blind hole diameter, the end that the knock pin is located the blind hole has the end cap with the blind hole clearance fit, the big envelope have with knock pin clearance fit's axle center hole, the outer peripheral face of big envelope have with insert upper blind hole opening part interior screw thread fit's external screw thread. The sleeve is sleeved on the top pin and fixed at the opening of the blind hole on the insert through the threads on the peripheral surface. The utility model has the advantages that: for current bullet knock pin subassembly, the utility model discloses can realize inserting openly to install and remove bullet knock pin liftout subassembly from last mould work, need not insert the dismantlement with last mould work when the installation is dismantled, make things convenient for the pincers worker installation to dismantle, save time, reduce the mould cost.
Description
Technical Field
The utility model belongs to the mechanical equipment field, concretely relates to stamping die annex.
Background
In the production of stamping dies, in order to assist the discharge of trimming waste of plates, a waste ejection device is often attached to an insert on an upper die base. The prior ejection device is shown in fig. 1 and 2: the device comprises a cylindrical top pin 2 arranged in a through hole comprising two sections of unequal-diameter holes on a working insert 1, a pressure spring 3 for pushing the top pin 2 and a plugging plug 4 arranged on one side end port of the through hole spring on the working insert. The end of the knock pin 2 at the depth of the hole has a shoulder at the larger diameter portion of the hole. In the working process of the die, the working insert 1 arranged on the upper die base and the working insert of the lower die complete shearing movement along with downward movement of the upper die, the ejection device is released from a release state to a compression state and then released from the release state, the ejector pin 2 firstly contacts a plate, then the spring 3 is compressed, the ejector pin 2 retracts into the insert 1 (figure 1), and the like, after the work is completed, the spring is changed from the retraction state to the release state, and pushes the ejector pin to extend out of the working end surface (figure 2) of the insert 1 to eject waste materials. Although the existing ejection device has the function of assisting in discharging waste materials, holes with different diameters need to be drilled on the insert, an ejector pin and a spring need to be installed in a hole of a through hole in the back face of the insert, then a plug is used for sealing, and the processing, the installation and the disassembly of the ejection device are relatively complex.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a punching press plate deburring waste material bullet top mounted putting for the supplementary discharge of waste material overcomes the above-mentioned not enough of supplementary waste material exhaust bullet top mounted putting among the prior art existence.
The utility model discloses a bullet top mounted putting includes: the blind hole of opening on inserting, the pressure spring of assembly bottom in the blind hole, the assembly is in the blind hole spring top held knock pin, assemble the big envelope at the blind hole opening part through the screw thread, knock pin diameter be less than the blind hole diameter, the end that the knock pin is located the blind hole has the end cap with blind hole clearance fit, the big envelope have with knock pin clearance fit's axle center hole, the outer peripheral face of big envelope have with insert upper blind hole opening part thread fit's external screw thread, the big envelope cover is on the knock pin, the big envelope passes through the screw thread of outer peripheral face to be fixed on the blind hole opening part on inserting
The utility model has the advantages that: compared with the existing ejection pin assembly, the ejection pin assembly can be assembled and disassembled from the front surface of the upper die working insert, the upper die working insert does not need to be disassembled during assembly and disassembly, the assembly and disassembly by a fitter are convenient, the time is saved, and the die cost is reduced.

Detailed Description
Referring to fig. 3, 4, 5 and 6, the pop-up device of the present invention includes: the blind hole-1 that opens on the insert 1, the pressure spring 3 that assembles in blind hole 1-1 inner bottom, the assembly in blind hole spring upper end supported by spring 3 knock pin 2, through the big envelope 5 of screw thread assembly in the blind hole opening part, 2 diameter of the said knock pin is smaller than blind hole 1-1 diameter, 2 end of knock pin in blind hole 1-1 have with blind hole movable fit end cap 2-1, 5 said big envelope have with 2 movable fit axle center hole 5-1 of knock pin, 5 peripheral surfaces of big envelope have with insert 1-1 opening part internal thread fit external screw thread 5-2. The sleeve 5 is sleeved on the ejector pin 2, and the sleeve 5 is fixed at the opening of the blind hole 1-1 on the insert 1 through the thread on the peripheral surface.
Claims (1)
1. The utility model provides a punching press plate deburring waste material bullet top mounted putting which characterized by: the blind hole assembly structure comprises a blind hole formed in an insert, a pressure spring assembled at the bottom end in the blind hole, a top pin assembled at the upper end of the spring in the blind hole and supported by the spring, and a jacket assembled at the opening of the blind hole through threads, wherein the diameter of the top pin is smaller than that of the blind hole, an end cap in the blind hole is arranged at the end of the top pin, which is positioned in the blind hole, of the top pin, a shaft center hole in movable fit with the top pin is formed in the jacket, an external thread in threaded fit with the opening of the blind hole in the insert is arranged on the outer peripheral surface of the jacket, the jacket is sleeved on the.
