Abstract
The utility model belongs to forging appliances and particularly relates to an improvement on the structure of a closed sleeve die. The closed sleeve die comprises an upper die, a lower die and a cushion block used for sealing a forge piece; the upper die is fixedly connected with the lower die below the upper die; the cushion block used for sealing a forge piece is embedded in the bottom of the lower die; the lower die comprises a die sleeve and a lower die seat; the upper part of the die sleeve is sleeved on and fixedly connected with the outer side of the upper die; and the inside wall of the bottom of the die sleeve is connected with the outer edge of the top of the lower die seat in an interference fit manner. The closed sleeve die provided by the utility model has the advantages of novel structure and economy of material.
Description
Technical field
The utility model belongs to the forging apparatus, particularly relates to a kind of architecture advances of enclosed sleeve mould.
Background technology
When forging all kinds of gear shaft, usually adopt the forging mode of enclosed sleeve mould, all-in-one-piece sleeve mould is often used in traditional forging, its structure as shown in Figure 1, comprise patrix 1, counterdie 2 and cushion block 3, patrix 1 is fixedlyed connected with the counterdie 2 of its below, and the cushion block 3 that is used to seal forging is embedded in counterdie 2 bottoms.The counterdie of this structure has only single parts, is integral structure, and all adopts die steel.Thereby to the also difficult processing of spool gear axle forging die monoblock type mould, in case a certain shelves of forging die size does not reach requirement, whole forging die just abandoned, thereby causes very big waste.
Summary of the invention
In order to increase the utilization rate of forging die material, overcome above deficiency.Goal of the invention of the present utility model provides a kind of novel structure, saves the enclosed sleeve mould of material.
Technical scheme that the utility model adopts is:
A kind of enclosed sleeve mould, comprise upper die and lower die and the cushion block that is used to seal forging, patrix is fixedlyed connected with the counterdie of its below, the cushion block that is used to seal forging is embedded in the counterdie bottom, described counterdie comprises die sleeve and die shoe, die sleeve top is set in the patrix outside and fixedlys connected with it, and the madial wall of die sleeve bottom is connected with the outward flange interference fit at die shoe top.
As preferably, also fixedly connected between described die shoe and the die sleeve by screw.
Adopt the enclosed sleeve mould of technique scheme, by improving existing integral type counterdie, make this counterdie comprise die sleeve and die shoe, die shoe top interference fit bottom die sleeve is connected, novel structure and being connected firmly.In the workpiece forging process, in case a certain shelves of forging die size does not reach requirement, existing enclosed sleeve mould is wanted and whole integral type counterdie can only be abandoned, thereby causes very big waste.And this structure of the utility model, the die sleeve in the counterdie but can use under the situation that meets the requirements in size gap repeatedly, and only discarded die shoe part is saved material.Major advantage of the present utility model is: novel structure, save material.
Description of drawings
Fig. 1: the structural representation of existing enclosed sleeve mould.
Fig. 2: the structural representation among the utility model embodiment.
The specific embodiment
Be described further this use is novel below in conjunction with drawings and Examples.
Embodiment: enclosed sleeve mould as shown in Figure 2, comprise patrix 4, counterdie and the cushion block 6 that is used to seal forging, counterdie is fixedlyed connected by screw 53 with die shoe 52 by die sleeve 51 and is constituted, counterdie is fixedlyed connected with patrix 4 by die sleeve 51, specifically be that die sleeve 51 tops are set in patrix 4 outsides and fixedly connected with it, the madial wall of die sleeve 51 bottoms is connected with the outward flange interference fit at die shoe 52 tops, screw 53 is in the interference fit junction of die sleeve 51 and die shoe 52, laterally run through die sleeve 51 to die shoe 52 from the outside, make die sleeve 51 and die shoe 52 be connected more firm.The cushion block 6 that is used to seal forging is embedded in die shoe 52 bottoms, and the material of above-mentioned die sleeve 51 can be 40Cr.And the material of die shoe 52 is a die steel, and die sleeve 51 can use under size gap meets the requirements situation repeatedly.Therefore, in the workpiece forging process,, can only change die shoe 52, will not change by whole counterdie, save material in case a certain shelves of forging die size does not reach requirement.
Claims (2)
1. enclosed sleeve mould, comprise upper die and lower die and the cushion block that is used to seal forging, patrix is fixedlyed connected with the counterdie of its below, the cushion block that is used to seal forging is embedded in the counterdie bottom, it is characterized in that described counterdie comprises die sleeve and die shoe, die sleeve top is set in the patrix outside and fixedlys connected with it, and the madial wall of die sleeve bottom is connected with the outward flange interference fit at die shoe top.
2. a kind of enclosed sleeve mould according to claim 1 is characterized in that also fixedlying connected by screw between described die shoe and the die sleeve.
