Description

A kind of eccentric flanging die of multi-notch

Technical field

The present invention relates to machined die technical field, especially a kind of eccentric flanging die of multi-notch.

Background technology

Flange refers to the edge of product translating into straight flange or the molding process of curl in the presence of mould, by turning over Side can make product have appropriate shape, either good rigidity (flange plays strengthening action) or make product have conjunction The spatial form of reason, space shared by product is reduced, therefore flanging process is widely used in actual production.

Cone barrel part is to form the eccentric flange of the notch of cone cylinder side wall, smaller or treat flange in the diameter of cone cylinder part Notch it is more when, due to the notch only cone cylinder axle center of flange, therefore, prior art using many set voussoir ejecting mechanisms with Flange notch is corresponded, and then reaches quality of the improvement to the eccentric flange of notch of cone cylinder side wall, improves cone barrel part Quality.But, bulky, the setting of many set voussoir ejecting mechanisms so that floor space is larger, and then should not answer of the mould For the flange process field of cone barrel part, and then cause the flange processing of cone barrel part in a kind of processing of non_mechanical State, and then cause that the labor intensity to the processing of the flange of cone barrel part is larger, cost is higher, and the quality of flange processing It is poor, it is less efficient.

The content of the invention

In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of multi-notch eccentric flange mold Tool, the mould is used on cone cylinder wall component, can either be realized the flange processing of the cone cylinder part of small diameter, can also be realized Treat the more part of flange notch and carry out batch processing, and then it is strong to reduce the work of the eccentric flange processing of cone cylinder part side Degree, improves the efficiency of flange processing, improves the quality of flange processing, the cost of reduction flange processing.

It is achieved particular by following technical scheme:

A kind of eccentric flanging die of multi-notch, including cope plate, are arranged on outer voussoir and interior voussoir on cope plate, lower mould Plate, is arranged on the angular block in lower template, sets fluted in lower template, and spring a is set in a groove, spring a one end Deduction is in groove on the vertical wall of outer voussoir, and spring a other end and the boss of flanging die are pushed against;It is arranged on lower mould Guide plate and block on plate;Flange cavity plate is provided between guide plate and block, flange cavity plate is in guide block, and is passed through Screw is inserted through spring b through block and is movably connected, and close in one end close to interior voussoir and guide plate;Guide block is set In lower template.

Between described outer voussoir and interior voussoir and cope plate connected by removable connector.

Described angular block is connected with lower template by removable connector.

Described guide plate and block is connected with lower template by removable connector.

Described guide block is that removable connector is connected with lower template.

Described flanging die can be slidably in guide plate.

Described flange cavity plate can be slidably in guide block.

Described removable connector is one kind in screw, pin.

Compared with prior art, technique effect of the invention is embodied in:

By setting outer voussoir and interior voussoir on cope plate, angular block is set in lower template, and groove is set, by bullet Spring a is set in a groove, and spring a one end is deducted in groove on outer voussoir vertical wall, and spring a other ends and flange are convex The boss of mould is pushed against;Guide plate and block are set in lower template;Flange cavity plate is provided between guide plate and block, flange is recessed Mould is in guide block, is inserted through spring b through block by screw and is movably connected, close to interior voussoir one end and guide plate It is close;Guide block is arranged in lower template, and mould die opening state is put into parts to be processed, and sets position with angular block;Hole flanging adds Man-hour cope plate is descending, and the inside and outside voussoir installed in cope plate promotes flange cavity plate and flanging die, completes flange, realizes cone Cylinder side wall flange mechanization production, reduction labor intensity, cost improve efficiency, it is ensured that quality.

By being disposed as dismountable active connection to the above-mentioned connection with cope plate and with the connection of lower template Connection, and then the easy to maintenance and convenient disassembly of follow-up equipment is ensure that, reduce the maintenance cost to flanging die.

It can be moved freely or be slided in zone of action by adjusting flange cavity plate therein and flanging die, Enter time that ensure that and can be realized when carrying out parts flanged-edge operation there is provided the efficiency of flange operation and dismounting flanging die Number.
