Description
Technical field
This utility model relates to a kind of technical field of metal formation, especially a kind of oval circle_curling die lamps structure.
Background technology
In many industrial products, some are used in capital needs the parts through pulleying circle processing, so-called volume circle processing technique refers to a part for an elongated member through punching press, this part is made to form the bending structure of a semicircle, current this processes needs through at least 3-4 procedure, and need staff to be operated, what not only produce is inefficient, and human cost is also significantly high, the cost causing enterprise declines, cut down the profit of enterprise further, it is unfavorable for the fast development of enterprise, and cause the cost increase of production, it is unfavorable for saving social resources, additionally, the operation of Product processing is more many, make a mistake or to produce the probability of substandard products also more high, thus causing the defect rate of product to raise, cost from another convenient production adding again product, the consumption causing social resources increases, furling plate round machine commercially at present, great majority are all that volume is bigger, inefficient.And the circle_curling die structure of these furling plate round machine is complicated, being typically necessary and complete volume circle by cylinder athleticism from the side, too increase production cost, unsightly, otch is irregular for processing work profile, there is the shortcomings such as burr.
Summary of the invention
For the deficiencies in the prior art, this utility model provides the oval circle_curling die lamps structure of a kind of good forming effect.
The technical solution of the utility model is: a kind of oval circle_curling die lamps structure, including punch press, mold and lower mold, described mold is arranged on punch press, described mold can move up and down under the effect of punch press, described lower mold is fixedly mounted in the frame below mold, it is characterized in that: described mold includes fixing, with mold main body, the wedge being connected, push rod, die-cut cutter head, described push rod is arranged on wedge side, described lower mold includes floating block, circle_curling die core, drive block, pusher circle, spring, described circle_curling die core is arranged on above lower mold forming part, described circle_curling die core is arranged with pusher circle from right to left successively, floating block, drive block, spring, described drive block is connected with pusher circle by connecting rod, by Spring driving pusher circle, shaping workpiece on circle_curling die core is released.
Described mold is provided with mold forming part, lower mold is provided with lower mold forming part.
Described push rod is arranged on the surface of floating block, drives the motion of direction, circle_curling die core downward mould molding portion by top rod driving floating block.
Described die-cut cutter head is positioned at the top of lower mold forming part.
Time actual die-cut, punch press drives mold to move downward, arrange wedge on the upper mold to move to being arranged on the drive block in lower mold, and drive block is stirred to spring direction, drive pusher circle to move to spring direction simultaneously, circle_curling die core front end is exposed, workpiece to be processed moves to circle_curling die core exposed end, sheet material material strip is cut off by die-cut cutter head, in the process that mold moves, workpiece to be added is stamped molding in mold forming part, until push rod top is to floating block, workpiece is completed preliminary molding by mold forming part, mold continues to move downward, workpiece lower ends bent is partially in lower mold forming part, under the punching press effect of mold, workpiece completes the volume circle molding of workpiece lower end in lower mold forming part, punch press drives mold to move upward, wedge also moves upward under the effect of mold and unclamps drive block, under the action of the spring, workpiece on circle_curling die core is pushed by pusher circle, complete to roll up round molding.
The beneficial effects of the utility model are: simple in construction, reasonable in design, and once volume circle molding, after first the lamellar section bar of strip is carried out in the forming part of upper die mold preliminary volume circle molding, the sweep of downside enters in the forming part of lower mold, then after mould opposing upper and lower extrudes mutually, complete to roll up round molding, make workpiece circle rolling molding smooth, greatly reduce the problems such as burr and the otch in die-cut volume circle process be irregular, substantially increase volume circle punching molding efficiency, decrease the generation of defective products, decrease production cost.
