Abstract

The utility model relates to a die, in particular to a carriage bolt combined die. The die structurally comprises a female die sleeve. One side inside the female die sleeve is provided with a lower die cushion, and the other side inside the female die sleeve is provided with a female die piece. An alloy die is arranged between the lower die cushion and the female die piece. According to the carriage bolt combined die, the die is structurally designed to be in the mode of combing the female die piece, the alloy die and the female die sleeve, the female die piece which is prone to being pressed can be directly replaced once damaged, die materials are greatly saved, and the service life of the die can be prolonged.

Description

A kind of carriage bolt assembling die
Technical field
The utility model relates to a kind of mould, particularly a kind of carriage bolt assembling die.
Background technology
Under prior art, for the processing of carriage bolt, the mold integral using is all to use the casting of 3Cr2W8V material to process, and it not only wastes mold materials, and the bad cracking phenomena that also often occurs of heat treatment, affects production efficiency, and die cost is higher.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of carriage bolt assembling die, and its structure is designed to the combining form of die sheet+alloy mould+die case, only changes die sheet after damage, greatly saves mold materials, can improve die life.
The technical scheme that the utility model adopts is as follows:
A kind of carriage bolt assembling die, comprises die case, and the inner side of die case is provided with lower die-cushion, and opposite side is provided with die sheet, between described lower die-cushion and die sheet, is provided with alloy mould.
Alloy mould comprises cemented carbide body, and described cemented carbide body outer setting has one deck Pre-stress cover.
Die sheet endoporus is square, the opposite side size of cubic opposite side size Control carriage bolt product, die sheet thickness moulding carriage bolt square neck height; Alloy mould material is SR15C sintered alloy, and effect is wear-resisting, improves die life.
Alloy mould outside is one deck Pre-stress cover, and because carbide alloy compression strength is higher, hardness is high, substantially there is no toughness, needs one deck Pre-stress cover to embrace it, while preventing upsetting, ftractures.
The effect of die case: die case endoporus and die sheet and alloy mould adopt interference fit, three is become one, die case cylindrical and Upper Die-sleeve endoporus play the guiding role, and bear upsetting strength (when Upper Die-sleeve is encountered lower die-sleeve, slide block movement stops, cup head and square neck upsetting moulding).
The beneficial effect that the technical scheme that the utility model provides is brought is:
A kind of carriage bolt assembling die of the present utility model, its mould structure is designed to the combining form of die sheet+alloy mould+die case, for the die sheet part of easily frequent pressurized, once only change die sheet after damaging, greatly save mold materials, more can improve die life.
Brief description of the drawings
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 skill in the art, 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 carriage bolt assembling die of the present utility model.
Detailed description of the invention
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 carriage bolt assembling die, comprises die case 1, and the inner side of die case 1 is provided with lower die-cushion 2, and opposite side is provided with die sheet 3, between described lower die-cushion 2 and die sheet 3, is provided with alloy mould 4.
Cemented carbide body outer setting has one deck Pre-stress cover.
Alloy mould comprises cemented carbide body, and described die sheet endoporus is square.
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 amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
