Abstract

The utility model relates to a mold, especially, relate to a shielding case upper cover turn -ups mould. Including formpiston 1, set up the lower bolster 6 in 1 below of formpiston, the upper surface from the bottom up of lower bolster 6 is fixed with backing plate 5, bed die 4, locating plate 3 in proper order, is provided with the ejector rod 2 through ejector pin 7 and elasticity tripper 8 swing joint in the cavity of backing plate 5, bed die 4, 3 formation of locating plate, is provided with on the bed die 4 and dodges groove 4 -1. Compared with the prior art, the utility model discloses the type has been owing to adopted above -mentioned technical scheme, fixes a position crooked mould for bending, one process and can accomplish the work that original setting -out and crooked twice process could be accomplished, has overcome a great deal of defects such as the process is loaded down with trivial details, cost of labor height, in addition, adopting turn -ups die positioning to carry out the turn -ups and replacing the setting -out location, its precision is high, the steady quality.

Description

Shielding box upper cover flanging die

Technical field

The utility model relates to a kind of mould, particularly relates to a kind of shielding box upper cover flanging die.

Background technology

As shown in figure 12, shielding the lid that closes is parts of thin-wall casing, and structure is comparatively complicated, comparatively strict to the coherence request of supporting installing hole, angle, flange height.When current processing shielding is closed and covered, usually through following operation: blanking-setting-out-bending-check and correction-bending-correction-boring.Owing to needing first to locate blanking on blanking mold, setting-out is carried out after having descended material, then twice bending on Bending Mould is transferred to, after transfer to again location drilling on hole drilling die, resetting can cause part processing precision to decline, bending position adopts setting-out mode to specify, and cause scale error large, and whole technique exists, and production process is loaded down with trivial details, efficiency is low, high in cost of production defect.Fig. 9 in order to overcome above weak point, processing method changed into blanking and punching-bending-curved-recurvation type, so can be located the mould carrying out being bent into part shown in Figure 10 ~ 11 by development automatically, becomes problem demanding prompt solution.

Utility model content

For the above-mentioned defect existed in prior art, the utility model aims to provide a kind ofly can locate the shielding box upper cover flanging die carrying out bending automatically.

To achieve these goals, the utility model is by the following technical solutions: comprise formpiston, be arranged on lower bolster below formpiston 1, the upper surface of lower bolster is fixed with backing plate, former, location-plate from top to bottom successively, be provided with the ejector that push rod is flexibly connected with elasticity discharger in the cavity that described backing plate, former, location-plate are formed, former is provided with escape groove.

Compared with the prior art, the utility model type is owing to have employed technique scheme, bending mould is positioned bending a, procedure and can complete the work that original setting-out and bending two procedures just can complete, overcome many defects such as operation is loaded down with trivial details, cost of labor is high; In addition, adopt flanging die location to carry out flange and replace setting-out location, its precision is high, steady quality.

Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

As shown in figs. 1 to 6, shielding box upper cover Bending Mould comprises formpiston 1, be arranged on lower bolster 6 below formpiston 1, the upper surface of lower bolster 6 is fixed with backing plate 5, former 4, location-plate 3 from top to bottom successively, be provided with the ejector 2 that push rod 7 is flexibly connected with elasticity discharger 8 in the cavity that described backing plate 5, former 4, location-plate 3 are formed, former 4 is provided with escape groove 4-1.Before bending, the workpiece shown in Fig. 9 is positioned on ejector 2, as shown in Fig. 7 ~ 8, under the promotion of power, formpiston 1 moves downward, and workpiece 9 is down compressed into row flange, after flange terminates, formpiston 1 is regained, elasticity discharger 8 promote push rod 7 move up eject workpiece 9.Adopt the part after the utility model bending as shown in Figure 10 ~ 11.
