Abstract

The utility model relates to a direct releasing mould for pressing and extending a shell cover of a cylinder. The utility model is composed of an upper template, a lower template, a concave mould, a concave mould gasket, a convex mould, etc. An elastic discharging device which is composed of an elastic component and a retreating slide block is arranged between the concave mould and the concave mould gasket. The retreating slide block is used for acting on the surface of the convex mould in a radial direction, when the convex mould returns and travels upwards, a workpiece which is packed on the convex mould is disassembled for stripping. Therefore, working strokes of a presser are shortened, and pressing speeds of the shell cover are enhanced; meanwhile, a crimping flange of the shell cover is cancelled, raw material is saved, and production cost is reduced.

Description

The straight stripper member that is used for the steel cylinder seal head calendering

The utility model relates to the straight stripper member in the field of rolling mould, particularly a kind of steel cylinder seal head molding.

In traditional steel cylinder seal head molding production process, must divide two operations to finish, at first suppress the end socket semi-finished product that the flanging flange is arranged at peristome with traditional calendering mould, then half-finished flange and fillet part lease making side cut operation are cut.Why will at the end socket peristome flanging flange be set artificially, be to be the stability of guaranteeing flanging in traditional calendering formation process and the quality of seal head molding.But there is not only tangible weak point in such design: 1. flange of Ya Chuing but also excision again, increased the consumption of material, and cost improves; 2. because the existence of flange can only cause the impulse stroke of press to increase respectively by special discharging, material jacking mechanism depanning between upper and lower mould behind the seal head molding, the pressing speed of press is restricted, production efficiency is difficult to improve.

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of both economical with materials are provided, reduce production costs, can shorten the press impulse stroke again, improving the straight stripper member of the steel cylinder seal head calendering usefulness of pressing speed.

The purpose of this utility model is achieved through the following technical solutions: the straight stripper member that is used for the steel cylinder seal head calendering, constitute by cope match-plate pattern, lower bolster, punch, die, cupped washer etc., special feature is equipped with elastic tripper between die and die packing ring, elastic tripper is by elastic component and return slide block and constitute; Under the elastic force of elastic component, the end face of returning slide block can act radially on the punch.Further, the elastic component of elastic tripper and returning in the groove that slide block is flush-mounted in the die packing ring, the end face top of returning slide block has chamfering.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are elaborated.

Structural representation when Fig. 1 is the utility model calendering end socket;

Structural representation when Fig. 2 is the utility model demoulding;

Fig. 3 is the structural representation of end socket workpiece.

Referring to Fig. 1, Fig. 2 and Fig. 3, the basic composition of the steel cylinder seal head of present embodiment calendering mould and traditional structure roughly the same promptly include cope match-plate pattern, lower bolster (not drawing among the figure), punch 1, die 2, die packing ring 5 etc.Die packing ring 5 is having the groove 6 of two symmetries with die 2 adjoiners, by spring 4 with return the elastic tripper that slide block 3 constitutes and be flush-mounted in the groove 6, return slide block 3 under the effect of spring 4 elastic force, its end face part is exposed to outside the inwall of die packing ring 5, and the end face top of returning slide block 3 has chamfering.

When the sheet material of using when moulding is put on the mould by the downward punching press of punch 1, sheet material is rolled, hug on punch 1, and directly form the steel cylinder seal head workpiece 7 (as shown in Figure 3) of no flanging flange, in the calendering formation process, workpiece 7 tightly encases punch 1, and it is descending to pass die 2 with punch 1, because being extruded with, the joint of die 2 and die packing ring 5 returns slide block 3, at 1 time stamping press of punch and return in the interaction of slide block 3 end face chamferings, returning slide block 3 is radially pressed and is retracted in the groove 6 (as shown in Figure 1), make punch 1 and workpiece 7 successfully enter in the die packing ring 5 fully, after workpiece 7 passes completely through die 2, the radial effect power that 7 pairs of workpiece are returned slide block 3 disappears, and returns slide block 3 and ejects under the effect of spring 4, and its end face acts radially on the punch 1.When punch 1 backhaul was up, the slide block 3 of returning of being close to punch 1 surface had stopped the stroke that hugs workpiece 7 on punch 1, thereby workpiece 7 is unloaded (as shown in Figure 2) from punch 1.After workpiece 7 unloads, directly fall into the receiving system of pipeline through lower bolster and workbench hole.

Adopt the structure of above-mentioned direct discharging, the demoulding, the utlity model has obvious advantage:

1, the impulse stroke of press greatly reduces, and the speed of pressing seal head can improve 25%;

2, workpiece can directly be fallen from lower bolster, workbench hole, be conducive to the automatic of workpiece Change conveying, improved production efficiency;

3, cancel the flanging flange of workpiece, reduced the loss of material, reduced production cost.

Claims

1, the straight stripper member that is used for the steel cylinder seal head calendering, by cope match-plate pattern, lower bolster, punch (1), die (2), die packing ring formations such as (5), it is characterized in that: between die (2) and die packing ring (5) elastic tripper is housed, elastic tripper is by elastic component (4) and return slide block (3) formation; Under the elastic force of elastic component (4), the end face of returning slide block (3) can act radially on the punch (1).

2, straight stripper member according to claim 1 is characterized in that the elastic component (4) of elastic tripper and returns in the groove (6) that slide block (3) is flush-mounted in die packing ring (5) that the end face top of returning slide block (3) has chamfering.
