Abstract
The utility model discloses a modified forging mould. The modified forging mould comprises a flaring block 1, a punching plunger chip 3, and a side shearing cutting edge 5, wherein the flaring block is arranged on an upper mould, the punching plunger chip is arranged on a lower mould, and the side shearing cutting edge is arranged on the lower mould. In the punching process of a press machine, the flaring block 1, the punching plunger chip 3, and the side shearing cutting edge 5 move downwards simultaneously, and three processes of flaring, side shearing and punching are completed simultaneously. The modified forging mould has the advantages of being capable of effectively decreasing machining process of products and improving working efficiency, and beneficial for increase of social benefits.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to the edge-cutting and hole-punching enlarging composite die of producing automotive hub.
Background technology
Forged hub is to finish through work steps such as forging, side cut, spinning.Energy-saving and emission-reduction are advocated in the whole world at present, and automotive field is more unexceptional, and in order to reach the purpose of energy-saving and emission-reduction, automotive dead weight develops to lightweight, and the lightweight of wheel hub is the most important to the factor of energy-saving and emission-reduction simultaneously.The side cut operation is necessary operation in the process of forged hub production, in order to reduce production process, enhances productivity, and reduces labour intensity, increases economic efficiency, and is badly in need of a kind of high efficiency, the composite die of casual labourer's order.
Summary of the invention
The purpose of this utility model provides a kind of can with the forging mold of side cut, punching, enlarging operation organic combination, reach the purpose that reduces production process, enhances productivity, reduces labour intensity, increases economic efficiency.
The technical solution of the utility model is: a kind of improved forging mold, expanding device, hole punched device, trimming device are set, press down in the process at forcing press, expanding device, hole punched device, trimming device be action downwards simultaneously, finishes simultaneously enlarging, side cut, punching three process.
As improvement of the present utility model, the utility model arranges enlarging piece, pierce punch, side cut cutting edge, the enlarging piece is arranged on patrix, pierce punch is arranged on counterdie, the side cut cutting edge is arranged on counterdie, press down in the process at forcing press, enlarging piece, pierce punch, side cut cutting edge be action downwards simultaneously, finishes simultaneously enlarging, side cut, punching three process.The enlarging piece plays the enlarging effect to the wheel rim position of workpiece, finishes the enlarging operation, for follow-up spinning operation is prepared; Under the interaction to workpiece, finish punching operation at the workpiece centre position at pierce punch and counterdie; , under the interaction to workpiece the forging overlap of workpiece is removed at cutting edge and counterdie, finished the side cut operation.
The utility model has the advantage of: can effectively reduce the manufacturing procedure of product, increase work efficiency, be conducive to economic benefit and improve.
Description of drawings
Fig. 1 is a kind of improved forging mold cut-away illustration of the utility model.
Among the figure: 1-enlarging piece, 2-workpiece, 3-pierce punch, 4-counterdie, 5-side cut cutting edge.
The specific embodiment
Embodiment 1, and a kind of improved forging mold arranges enlarging piece 1, pierce punch 3, side cut cutting edge 5, and the enlarging piece is arranged on patrix, and pierce punch is arranged on counterdie, and the side cut cutting edge is arranged on counterdie.Press down in the process at forcing press, enlarging, side cut, punching three process are finished in the simultaneously action downwards of enlarging piece 1, pierce punch 3, side cut cutting edge 5 simultaneously.The enlarging effect is played at the wheel rim position of 1 pair of workpiece 2 of enlarging piece, finishes the enlarging operation, for follow-up spinning operation is prepared; Under the interaction of pierce punch 3 and 4 pairs of workpiece 2 of counterdie, finish the punching operation in workpiece 2 centres; Under the interaction of side cut cutting edge 5 and 4 pairs of workpiece 2 of counterdie, the forging overlap of workpiece 2 is removed, finish the side cut operation.
Utility model provides a kind of can with the composite die of side cut, punching, enlarging operation organic combination, reach the purpose that reduces production process, enhances productivity, reduces labour intensity, increases economic efficiency.Edge-cutting and hole-punching enlarging composite die is not limited to the scheme that the drawings and specific embodiments are described, and the similar mould with edge-cutting and hole-punching enlarging complex method all falls into the scope of the utility model protection.
