Abstract
The utility model relates to the technical field of male dies and in particular relates to a straight-through type male die fixing device related to core bar extrusion. The device comprises a male die fixing ring, a male die, a clamping block and a core rod, wherein the upper end of the male die is provided with a fan-shaped clamping groove; the clamping block attached to the male die and the fixing ring is arranged between the male die and the fixing ring; a bayonet part of the clamping block is clamped in the fan-shaped clamping groove of the male die; the other parts of the clamping block are arranged on steps of the male die fixing ring; and the top end of the clamping block is flush with the top end of the male die. Compared with the prior art, the straight-through type male die fixing device has the advantages that the structure is novel and simple, the use convenient, the top end of the clamping block is flush with the top end of the male die, the device serves as a bearing base plate in the vertical direction so as to enlarge the bearing area of the male die and serves as a fastening ring in the circumferential direction, the male die can be conveniently fixed and can be prevented from slipping, the working efficiency is improved, and the device is low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of fixture unit for straight-through type terrace die.
Background technology
The punch of conventional extrusion dies is revolving body normally, generally adopts step or frustum to be fixed method, in recent years, controls the development of forming technology along with extruding, and increasing complex parts can adopt extrusion process to complete.Extruding punch for complex appearance still adopts the fixed form of revolving body punch at present, cause to adopt two-part in punch processing, be that punch top is band step or inversed taper platform revolving body, punch bottom working portion is by the spark machined profile, then reaches required precision by polishing.And adopt the high-precision wire cutting that punch is processed into through type, and can simplify the punch processing technology, improve and make efficient and precision.But extrusion die is different from general diel, can adopt the mode of riveted joint to fix at the general middle-size and small-size through type punch of diel, and large-scale through type punch can adopt the screw lifting.And the stripping force of extrusion process is far longer than the punching press stripping force, and fixedly the through type punch is unreliable to adopt riveted joint; On the other hand, the extruding punch of cored bar leaves through hole for placing the plug center, can not adopt the mode of screw lifting, and therefore, how the through type extruding punch of fixed band plug is the difficult problem of the common existence of an industry.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure and through type extruding punch fixture effectively fixed band plug.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of fixture unit for straight-through type terrace die, comprise punch retainer plate, punch, fixture block and plug, on described punch retainer plate, the step through hole is arranged, punch is arranged in the step through hole, described plug is positioned at the stepped hole of the setting on punch, the punch upper end is provided with draw-in groove, be provided with the fixture block that cooperatively interacts with described draw-in groove between punch and retainer plate, described fixture block is provided with bayonet socket, described bayonet socket is placed in described draw-in groove when coordinating, and described draw-in groove is for having biapiculate crescent shape arcuate structure.
The beneficial effect main manifestations of a kind of fixture unit for straight-through type terrace die of the utility model is: simple in structure easy to use, the card tight loop can prevent landing, and meniscate draw-in groove has better fitment stability energy.
Description of drawings
Fig. 1 is the structural representation of the utility model fixture unit for straight-through type terrace die.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model specific embodiment is described:
With reference to Fig. 1, a kind of fixture unit for straight-through type terrace die of the present utility model, it comprises punch retainer plate 1, punch 3, fixture block 2 and plug 4, on described punch retainer plate 1, the step through hole is arranged, punch 3 is arranged in the step through hole, described plug 4 is positioned at the stepped hole of the setting on punch 3, punch 4 upper ends are provided with draw-in groove, be provided with the fixture block that cooperatively interacts with described draw-in groove between punch 4 and retainer plate 1, described fixture block is provided with bayonet socket, described bayonet socket is placed in described draw-in groove when coordinating, and described draw-in groove is for having biapiculate crescent shape arcuate structure.
The above has done detailed description to the utility model preferred embodiment by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from the utility model aim.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
