Abstract
The utility model relates to a mold, in particular to a triangular head connecting bolt forming process mold. The triangular head connecting bolt forming process mold is structurally composed of a punch pin mechanism and a female mold mechanism. The punch pin mechanism comprises a punch pin sleeve, the front of the punch pin sleeve is connected with a rear punch pin sleeve cushion, a punch pin cushion block is arranged inside the punch pin sleeve, an upper punch pin is arranged in a hole in the rear of the punch pin sleeve, a rear upper punch pin cushion is arranged between the upper punch pin and the punch pin cushion block, and punch pin springs are arranged between the punch pin cushion block and the punch pin sleeve. The female mold mechanism comprises a lower mold sleeve, a lower mold, an alloy mold, a chamfering mold and a female mold cushion block are sequentially arranged inside the lower mold sleeve from front to back, a female mold sleeve thread cushion is arranged between the female mold cushion block and the lower mold sleeve, a rear female mold sleeve cushion is arranged behind the female mold sleeve thread cushion, and a charging punch penetrates through the center of the lower mold, the center of the alloy mold, the center of the chamfering mold, the center of the female mold cushion block and the center of the rear female mold sleeve cushion. The triangular head connecting bolt forming process mold has the advantages of being reasonable in design, simple in structure, convenient to maintain and capable of reducing production cost, and the forming process of a blank obtained after upsetting can be directly finished through a cold header.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of trigonocephalia connecting bolt molding procedure mould.
Background technology
Under prior art, trigonocephalia connecting bolt product nose shape is special, triangular in shape, the lower cylindrical of head and bottom surface R transition.Domestic production technology goes out the hot Upsetting moulding of wing on being all, rear neat wing after hot upsetting.This technique is very complicated, and the mould structure using during enforcement is complicated, causes production cost to increase, and production efficiency reduces.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of trigonocephalia connecting bolt molding procedure mould.It adopts movable ram structure, can utilize cold headers directly to complete the molding procedure of the blank that upsetting completes.
The technical scheme that the utility model adopts is as follows:
A kind of trigonocephalia connecting bolt molding procedure mould, by plunger mechanism and die mechanism, formed, plunger mechanism comprises drift cover, after connecting drift cover, described drift cover the place ahead pads, described drift cover inside is provided with ram block, in described drift cover rear square hole, upper punch is set, pads after upper punch is set between described upper punch and ram block, described ram block arranges drift spring before with drift cover; Described die mechanism comprises lower die-sleeve; described lower die-sleeve inside is disposed with counterdie, alloy mould, chamfering mould and die cushion block from front to back; die mantle fiber pad is set between described die cushion block and lower die-sleeve; after described die mantle fiber pad rear arranges die case, pad, described counterdie, alloy mould, chamfering mould, die cushion block and die case Hou Dian center are interspersed with the punching that feeds intake.
Between counterdie and lower die-sleeve, adopt tiltedly cover interference fit.
Upper punch adopts movable ram, by nose shape, be designed to leg-of-mutton upper punch by drift spring action, blank after in advance upsetting operation being completed pushes counterdie, blank direction is consistent with counterdie direction, when mould moves to front dead point, a upper punch front end part enters counterdie, head upsetting moulding (with R transition subtriangular).
The benefit that upper punch enters counterdie is in advance to align by upper and lower mould, and avoid shunting improper drift and counterdie collide the mould causing and damage.Counterdie and lower die-sleeve adopt tiltedly cover interference fit, and with the locking of die mantle fiber pad, during upsetting, counterdie can not retreat, and can guarantee the magnitude of interference, prevents counterdie cracking.Counterdie adopts LD steel to do, and after damage, can change, and other moulds need not be changed, and can reduce die cost.
The beneficial effect that the technical scheme that the utility model provides is brought is:
A kind of trigonocephalia connecting bolt molding procedure mould of the present utility model, its have reasonable in design, simple in structure, be convenient to the feature safeguarding, reduce production costs, it utilizes cold headers can directly complete the molding procedure of the blank that upsetting completes.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of trigonocephalia connecting bolt molding procedure mould of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment mono-
As shown in Figure 1, a kind of trigonocephalia connecting bolt molding procedure mould, by plunger mechanism and die mechanism, formed, plunger mechanism comprises drift cover 3, described drift overlaps 3 the place aheads and connects pad 6 after drifts cover, and described drift overlaps 3 inside and is provided with ram block 4, and described drift overlaps upper punch 1 is set in 3 rear square holes, after upper punch is set between described upper punch 1 and ram block 4, pad 2, described ram block 4 arranges drift spring 5 before with drift cover 3; Described die mechanism comprises lower die-sleeve 9; described lower die-sleeve 9 inside are disposed with counterdie 7, alloy mould 8, chamfering mould 10 and die cushion block 11 from front to back; die mantle fiber pad 12 is set between described die cushion block 11 and lower die-sleeve 9; after described die mantle fiber pad 12 rears arrange die case, pad 13, described counterdie 7, alloy mould 8, chamfering mould 10, die cushion block 11 and die case Hou Dian 13 centers are interspersed with the punching 14 that feeds intake.
Between counterdie 7 and lower die-sleeve 9, adopt tiltedly cover interference fit.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
