Abstract
The utility model relates to a flanging positioning structure of a spring seat, which improves the flanging quality of products by lower cost and comprises a positioning core for positioning a front material piece of a flanging and a flanging core for flanging hole forming of the material piece. The flanging positioning structure of the spring seat is characterized by also comprising a supporting seat for connecting a mold fixing plate; the positioning core, the flanging core and the supporting seat are three separated members; a fastening screw inserts into the positioning core, the flanging core and the supporting seat simultaneously to fixedly connect the positioning core, the flanging core and the supporting seat together; and the flanging core is positioned between the positioning core and the supporting seat.
Description
Technical field
The utility model relates to a kind of location structure that is applicable to flanging process.
Background technology
As shown in Figure 1, the flange location structure of spring base cold-work die comprises location core 2 and flange core 6, when work, tablet 3 is enclosed within on the core 2 of location before the flange, and finish flange by the flange working position 4 of flange core 6, obtain tablet 5 behind the flange, the flange location structure is fixed on the mold fixed plate 8 by flange core stiff end 7, and location core and flange core 6 are fixed together by trip bolt 1.
Because the gap that fixedly belongs between location core 2 and the flange core 6 is fixed, there is not circumferential location structure, be easy to generate play in the fixed pan side direction, cause in the flange flange hole technology of spring base cold-work die, hole flanging often produces the situation of hole flanging off-centre, the serious plucking in product working position, causes product to scrap in a large number; The holding screw 1 easily broken (being subjected to the effect of side force when working for screw by analysis) of flange body in addition, flange core working position 4 serious wear, often need to change spare part, expense has high input, if the coating surface coating improves the flange product quality on flange core 6, just need be coated with, produce too much waste flange core integral body (containing stiff end 7).
The utility model content
The purpose of this utility model is to provide a kind of spring base flange location structure, improves product flange quality originally with lower one-tenth.
For realizing described purpose, spring base flange location structure of the present utility model, comprise and be used for location core that tablet before the flange is positioned and the flange core that carries out the hole flanging moulding greater than tablet, be characterized in, also comprise supporting base, supporting base is used to connect mold fixed plate, location core, flange core and supporting base are three separating members, and trip bolt inserts location core, flange core and supporting base simultaneously and will locate core, flange core and supporting base and be fixed together, and the flange core is being located between core and the supporting base.
Described spring base flange location structure, its further characteristics be, the flange core has and prevents that tablet is by the face coat of flange plucking.
Described spring base flange location structure, its further characteristics are that the contact-making surface between location core and the flange core has circumferential location structure, and the contact-making surface between flange core and the supporting base also has circumferential location structure.
Described spring base flange location structure, its further characteristics are that described circumferential location structure is circumferentially to locate the shaft shoulder.
Described spring base flange location structure, its further characteristics are that the described circumferential location shaft shoulder is the conical surface.
The beneficial effects of the utility model are:
Former flange location structure adopts location-flange disome formula structure, and the utility model changes the trisome formula structure of location-flange-fixedly into; Flange location structure of the present utility model all adopts between structure and structure circumferentially to locate to take on the bolt thread fastening means and fixes, and has prevented that product from producing the hidden danger of quality of hole flanging off-centre, has stopped screw simultaneously because of being subjected to the phenomenon that side force often ruptures; The flange active section is separated from original turnup structure integral body, become the flange core, and carry out face coat and handle,, reduce the generation of part hole flanging plucking phenomenon to increase abrasion-resistant surface; Because it is a lot of that new flange core lacks than the volume of original flange core, so the expense of PVD is than reduction greatly originally; When producing, be damaged in addition, can keep in repair at the scene, only need change corresponding spare part, just can finish maintenance work in 5 minutes, very convenient; Must stop line 1-2 hour and damage in the past, carry out the mould unloading maintenance.
Description of drawings
Fig. 1 is the front view of the spring base flange location structure in the prior art.
Fig. 2 is the front view of spring base flange location structure of the present utility model.
The specific embodiment
As shown in Figure 2, spring base flange location structure of the present utility model comprises location core 2, flange core 7 and supporting base 5, location core 2, flange core 7 and supporting base 5 are members of three separation, flange core 7 is between location core 2 and supporting base 5, the three links together by trip bolt 1, contact-making surface between location core 2 and the flange core 7 has circumferential location structure, the contact-making surface of for example locating the upper end of the lower end of core 2 and flange core 7 is an on-plane surface, contact-making surface between flange core 7 and the supporting base 5 also has circumferential location structure, for example the contact-making surface of the upper end of the lower end of flange core 7 and supporting base 5 is an on-plane surface, therefore after the three links together, location core 2, circumferentially also being positioned of flange core 7, limited the location core, the horizontal looseness of flange core, thus the position degree in moulding hole guaranteed, do not produce off-centre.Supporting base 5 has supporting base stiff end 6, supporting base stiff end 6 fixedly connected mold fixed plates 9, thus whole spring base flange location structure is fixed on the mould.In when work, spring base tablet 3 is enclosed within on the core 2 of location, and finishes the flange moulding process by flange core 7, obtains the spring base tablet 4 after the moulding.On the flange core 7 coating is arranged, PVD coating for example, take place with the situation of improving product flange plucking, and because flange core 7 and supporting base 5 are separating member, need not to be provided with coating on the supporting base 5, the coating area reduces greatly, if the flange core damages, directly change flange core 7 and just finished repairing, very economical.
Describe the circumferential location structure between location core 2 and flange core 7, flange core 7 and the supporting base 5 below again in detail.
In the embodiment that Fig. 2 implemented, the upper and lower side of lower end, the flange core 7 of location core 2 and the upper end of supporting base 5 all are formed with the circumferential location shaft shoulder 8 (conical surface of corner among the figure for example, but be not limited thereto, can be any face that can realize circumferential location), after location core 2, flange core 7 and supporting base 5 link together by trip bolt, the corresponding circumferential location shaft shoulder 8 contacts cooperate, thereby have limited the horizontal looseness that may exist of locating core 2, flange core 7.
