Abstract

Disclosed is a chain sheet hole repairing device. The device comprises a punching die and a pad die. The punching die is disposed on a plunger chip of a punching machine. The pad die is disposed on a pad plate of the punching machine. A fixing plate of the punching die is provided with two punching rods. The pad die is in the shape of a cabinet. The center of the pad die is provided with a chain sheet positioning chamber. The upper end surface of the cabinet is provided with two punching rod inlet holes, and the lower end surface of the cabinet is provided with two waste outlet holes. The three side surfaces of the cabinet are enclosed. One side surface of the cabinet is provided with a through hole used for allowing the chain sheet to lead in and out. The waste outlet holes are disposed corresponding to through holes on the pad plate. The chain sheet is disposed into the chain sheet positioning chamber through the through hole used for allowing the chain sheet to lead in and out. The chain sheet positioning chamber is provided with a chain sheet positioning block. Installation holes at two ends of the chain sheet, the punching rod inlet holes on the pad die and the waste outlet holes on the pad die share the same axis. By adopting the above-mentioned technical scheme, the chain sheet punched for the first time is put into the dies of the chain sheet hole repairing device to be positioned. The chain sheet hole repairing device is used for carrying out secondary punching on installation holes of the chain sheet. The punching rods of the punching die flatten tearing areas on the surface of the installation holes of the punching rods, so that the rough tearing areas in the installation holes are eliminated.

Description

Chain sheet is repaiied aperture apparatus
Technical field
The utility model belongs to chain manufacturing technology field, relates to a kind of chain sheet and repaiies aperture apparatus.
Background technology
Chain conventional in industrial production is made up of chain sheet, connecting axle and axle sleeve, two ends at chain sheet have installing hole, connecting axle is installed in hole, the two ends of connecting axle are all provided with chain sheet, and every one end is provided with two chain sheets, two chain sheets are connected to form chain with the axle collar ring that is connected of front and back respectively, on some large-sized chains, lining is also installed in the installing hole of chain sheet, and connecting axle is arranged on lining.The method that the installing hole of chain sheet is commonly used is during fabrication pressing, the installing hole stamping machine that is chain sheet two ends is one time punching molded, in actual production, because the manufactured materials of chain sheet has certain adhesive, installing hole is in the time of punching press, the surface in hole can form tear-strap, and tear-strap causes installing hole rough surface, affects the installation of lining or connecting axle.
Summary of the invention
For solving in prior art, there is tear-strap in chain sheet installing hole surface after punch forming, affect the installation of lining or connecting axle, the utility model provides a kind of chain sheet to repair aperture apparatus, this device forms by rushing film and padding film two parts, rush on the drift that film is arranged on punch press, pad mould is arranged on the backing plate of punch press, on the fixed head of punch die, be provided with two and rush post, pad film is box shape, there is chain sheet positioning chamber at middle part, on casing upper surface, have two and rush post hand-hole, on lower surface, having two waste materials portals, three side-closed of casing, on a side, leave the import and export of chain sheet, waste material portal with backing plate on through hole contraposition install, chain sheet packs into chain sheet positioning chamber from the import and export of chain sheet, in chain sheet positioning chamber, be designed with chain sheet locating piece, the installing hole at chain sheet two ends with pad on film rush post hand-hole and waste material portals on same axis.
Adopt technique scheme, chain sheet with tear-strap in installing hole after a punching press is placed in mould of the present utility model, position at mould inner chain sheet is fixed, the installing hole of chain sheet is carried out to two times punch with the utility model, the post that rushes of punch die is bulldozed the tear-strap on installing hole surface, thereby eliminates coarse tear-strap in installing hole.
Adopt after technical solutions of the utility model, when chain sheet was installed in the later stage, installing hole is smooth neat, and lining and connecting axle are installed smooth and easy, does not need the hammering of manually polishing again with by force to install, and the quality of workpiece improves greatly.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 be in Fig. 1 A-A to cross-sectional view.
Fig. 3 is the perspective view of chain sheet.
The specific embodiment
As shown in Figure 3, in the prior art, the interior tear-strap 15 that exists of the installing hole 10 of chain sheet 13, the utility model designs for solving the interior tear-strap 15 that exists of installing hole 10, and specific embodiments is as follows:
Embodiment: as depicted in figs. 1 and 2, a kind of chain sheet is repaiied aperture apparatus, form by rushing film 3 and padding film 6 two parts, rush on the drift 1 that film 3 is arranged on punch press, pad mould 6 is arranged on the backing plate 7 of punch press, on the fixed head 2 of punch die 3, be provided with two and rush post 4, pad film 6 is box shape, there is chain sheet positioning chamber 5 at middle part, on casing upper surface, have two and rush post hand-hole 9, on lower surface, have two waste materials and portal 11, three side-closed of casing, on a side, leave the import and export 14 of chain sheet 13, waste material portal 11 with backing plate 7 on through hole 12 contrapositions install, chain sheet 13 packs into chain sheet positioning chamber 5 from the import and export 14 of chain sheet, in chain sheet positioning chamber 5, be designed with chain sheet locating piece 8, on the installing hole 10 at chain sheet 13 two ends and pad film 6 rush post hand-hole 9 and waste material portals 11 on same axis.
