Detailed Description

The invention will be further explained with reference to the following figures and examples:

Referring to fig. 1 to 4, a piston gate punching machine for removing a gate between two cast pistons 8 includes a punching machine body 1, a piston 8 positioning structure is fixed on a punching table 3 of the punching machine body 1, the piston 8 positioning structure includes two fixed knives 6 fixed symmetrically, a first positioning seat 4 for positioning a left piston 8 is fixed on the left side of a first shearing knife 12 of the punching table 3, a second positioning seat 13 for positioning a right piston 8 is fixed on the right side of a second shearing knife 12 of the punching table 3, and a shearing knife 12 corresponding to the two fixed knives 6 is further fixed on a punching head 2 of the punching machine body 1.

When the utility model is used, the two pistons 8 are positioned by the first positioning seat 4 and the second positioning seat 13 when the sprue 9 in the middle of the piston 8 needs to be punched and cut, after the piston 8 is positioned by the two positioning seats, the punching head 2 of the punching machine body 1 is started, the punching head 2 punches downwards to drive the shearing knife 12 on the punching machine body to move downwards, and when the shearing knife 12 shears downwards, the shearing knife is matched with the fixed knife 6, the sprue between the two pistons 8 can be cut, then the punching head 2 is lifted again, then the piston 8 at the left side is turned over by 180 degrees, the piston 8 at the right side is also turned over by 180 degrees, so that the outer sprue 10 of the piston 8 is abutted with the fixed cutter 6, the punch head 2 then punches downward again to punch out the outboard gate from the piston 8, completing the removal of the gate from the piston 8.

Further, the fixed knife 6 comprises a horizontal connecting plate 7 and is fixed on the punching table 3 through the horizontal connecting plate 7. In order to facilitate the connection of the fixed knife 6, the fixed knife 6 comprises a vertical knife edge and a horizontal connecting plate 7, and the fixed knife 6 can be rapidly fixed and detached through the horizontal connecting plate 7, so that the fixed knife is convenient to install or replace.

Furthermore, a blanking hole 11 is formed in the punching table 3 between the two fixed cutters 6, the blanking hole 11 is a long-groove through hole, and the length of the long-groove through hole is greater than that of a sprue between the two pistons 8. After the gate between the two pistons 8 is cut off, the operator takes it up, rotates it by 90 degrees to directly drop the gate from the blanking hole 11, and after the gate part outside the piston 8 is cut off, the gate can also drop from the blanking hole 11, and in addition, a material sliding table 14 can be arranged in the middle of the support table at the bottom of the stamping table 3, the upper surface of the material sliding table 14 is inclined towards the rear part of the stamping table, and the cut gate can directly slide from the material sliding table 14 to the rear part.

further, first positioning seat 4 and second positioning seat 13 are L type seat, be fixed with a retaining ring 5 on the riser of L type seat, the internal diameter of retaining ring 5 and the external diameter phase-match of piston 8 specific, the utility model discloses a all be fixed with a retaining ring 5 on the riser of two positioning seats, because the hole of piston is anomalous hole, so the utility model discloses a it fixes a position the outside of piston to the retaining ring, after the runner at two piston middle parts is got rid of, the piston can rotate in retaining ring 5, this retaining ring 5's setting, piston 8 that can be quick fixes a position, after piston 8 location, two pistons 8 can remain stable state when die-cut, after the runner between equivalent weight piston 8 is die-cut, abandons the runner at the middle part from blanking hole 11, after punching head 2 upwards resets, rotates 180 degrees respectively with left side piston 8 and right side piston 8 for outside runner 4 and fixed knife 6 contact, punching head 2 is die-cut once more, makes outside runner 4 by the die-cut that the runner was abandoned smoothly in the blanking hole, finally can follow the blanking hole 11 with the outside 4.

further, be fixed with a thickening portion 16 on the horizontal plate of L type seat, an arc constant head tank 15 has still been seted up on thickening portion 16 the utility model discloses an arc constant head tank 15 has been seted up on the horizontal plate of L type seat, this arc constant head tank 15 and piston 8 are the assorted for piston 8 obtains certain support in the location, still makes when pegging graft the holding ring with piston 8, has certain guide effect, can realize quick location.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation.
