Description

A kind of reverse-drawing mould of carry magnet

Technical field

The utility model relates to field of machining, specifically a kind of reverse-drawing mould of carry magnet.

Background technology

Along with social progress and the fast development of mechanical industry, with the integral intelligent mechanical processing machine of the manipulator more and more heavier role that bears the responsibility in machining, be also one of important directions of following mechanical industry upgrading. In order to meet the requirement of the novel lathe with manipulator, need to re-construct reverse-drawing mould.

In the prior art, some reverse-drawing moulds can not meet the requirement of the integral intelligent lathe with manipulator, and some problems that exist in reverse-drawing have caused very large impact to producing. These problems comprise: 1, reverse-drawing mould adopts the mode of manual feeding, and production of machinery efficiency is lower, and labour cost is higher, and easily security incident occurs; 2, reverse-drawing mould is to after part processing, and part has by patrix and takes up, thereby occurs the generation of the phenomenons such as the crooked or bullet of part flies; 3, part is after the processing of reverse-drawing position, and part lower end can be close to drawing die bed die, has increased the contact area of part internal layer and mould, thereby has increased friction, is not easy to the picking-up operation of manipulator to part.

The patent No. is that 201220559695.3 Chinese patent discloses a kind of reverse-drawing mould. Its reverse-drawing mould can carry out binder and reverse-drawing to material, but its weak point is can be close to die and push rod after materiel machining, and the frictional force between material and mould is larger, is not easy to the taking-up of material, thereby has reduced productivity ratio; In a large amount of production, thereby there will be material to be taken up and make the phenomenon that material is crooked or bullet flies by mold. Above phenomenon all can not meet accurately crawl and stable requirement of dragging material away of manipulator.

Utility model content

For the deficiencies in the prior art, the technical problem that the utility model quasi-solution is determined is, a kind of reverse-drawing mould of carry magnet is provided, and this mould accurate positioning, precision are high, and can prevent reverse-drawing part takeoff or crooked, structure optimization, pickup are easy. This reverse-drawing mould, adopt manipulator self-feeding mode, can ensure that material inhales stably on mould, material lower end after processing can be spaced apart with lower mould, reduce the frictional force of material and mould, and can treat stably on mould, be convenient to manipulator and accurately capture and stablize holder and walk material.

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is carried out to further clear, complete description. Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiment. Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope that the utility model claim is protected.

The utility model provides a kind of reverse-drawing mould (being called for short reverse-drawing mould or mould, referring to figure 1 ?3) of carry magnet, comprises patrix 1, counterdie 2 and material securing device 3;

Described patrix 1 comprises cope match-plate pattern 12, upper spring 11, dnockout core 13, drift 14 and punch fixing plate 15; Described spring 11 is positioned at the top of cope match-plate pattern 12 inside, dnockout core 13, and when punching machine presses material, dnockout core 13 moves upward, compression upper spring 11, thus upper spring 11 can press down dnockout core 13, and dnockout core 13 is rebounded downwards, and material 51 is separated with drift 14; Described dnockout core 13 is positioned at drift 14 inside, and drift 14 positions dnockout core 13, and dnockout core 13 can move up and down; Described punch fixing plate 15 is embedded in the groove of cope match-plate pattern 12, is bolted and is connected with cope match-plate pattern 12.

Described counterdie 2 comprises lower mold core 20, anti-die 21, anti-die block 25, base 24, lower spring 23, the pad 22 of drawing of drawing; Described base 4 is fixedly connected with punch press; The described anti-die block 25 that draws is embedded on base 24 grooves, is fixedly linked with base 24 use bolts; The described anti-die 21 that draws is positioned at anti-die block 25 inside of drawing, and to draw die block 25 to be fixed it spacing by counter; Described lower mold core 20 is positioned at anti-die 21 inside of drawing, and can move up and down; Described pad is between lower mold core 20 and lower spring 23; Described lower spring 23 is positioned at pad 22 belows, and support pad 22 and lower mold core 20, when punching machine presses material, when lower mold core 20 moves downward, can compress lower spring 23, and the lower mold core 20 thereby lower spring 23 can rebound, makes to move on it.

Described material securing device 3 comprises retainer core 34, cylindrical magnet 33, bolt 32, medi-spring 31, nut 30; Described retainer core 34 is positioned at lower mold core 20 inside, its upper surface higher than lower mold core 20 upper surfaces 2 ?3mm, can move up and down; Described cylindrical magnet 33 is positioned on the locating hole of retainer core 34 inside, fixes with AB glue; Described medi-spring 31 is positioned at lower mold core 20 inside, and retainer core 34 is supported in the bottom of retainer core 34, and in the time of material down-pressing forming, retainer core 34 moves down, and compression medi-spring 31, makes to move on retainer core 34 thereby medi-spring 31 can apply power; Described bolt 32 runs through retainer core 34 and lower mold core 20 by through hole 44, and fixing by the nut 30 that is positioned at lower mold core 20 bottoms, bolt 32 plays spacing effect to retainer core 34.

The operation principle of the utility model mould and workflow: when material is put into after lower mold core 20, punching machine presses, dnockout core 13 contacts upwards retraction with material, and extruding upper spring 11, until drift lower surface is following with drift 14, lower surface is equal. Drift 14 pressing materials, complete reverse-drawing, and in the time that punch press gos up, dnockout core 13, under the elastic force of upper spring 11, can separate material 51 with drift 14 completely, prevents that material 51 from being taken up by drift. In the process pressing down at drift 14, retainer core 34 moves downward under material pressure, and extruding medi-spring 31, until retainer core 34 upper surfaces are equal with lower mold core 20 upper surfaces; Under the effect that lower mold core 20 presses down at drift 14, move downward, can enter anti-die 21 inside of drawing, extruding lower spring 23, until punch press lowest order; After punching machine presses lowest order, go up, in the time that drift 14 leaves material, lower mold core 20 is counter to be popped into position, retainer core 34 moves upward under the counter-force of medi-spring 31, material 51 good reverse-drawing is held up, under the effect of magnet 33, material 51 can be inhaled on retainer core 34 stably, and can be not crooked or bullet fly; After whole operation completes, manipulator can decline and put in place, can accurately hold up stably material, transports to next operation.

The utility model mould is not addressed part and is applicable to prior art.
