Abstract
The utility model relates to a detachable upper punch die. The detachable upper punch die comprises a die sleeve, the middle of the die sleeve is provided with a cavity, and the top of the die sleeve is provided with an exhaust hole which is communicated with the cavity; a large cushion plate is arranged inside the cavity, a movable punch is pressed onto the large cushion plate through a fixed pressing seat, the fixed pressing seat is fixed through die sleeve pressing pins inserted from both sides, and the movable punch is made of H13 steel materials. The detachable upper punch die can save high die expenses, achieve rapid switching among products of different specifications and accordingly achieve the aim of reducing the cost and improving the working efficiency.
Description
Technical field
The utility model belongs to mould applications, is specifically related to a kind of detachable upper punch mould.
Background technology
Aluminum alloy forge piece has application more widely in relevant industries such as engineering machinery, textile machine, communications and transportation, Aero-Space as load-carrying member, forge die can save material, greatly reduce follow-up machined and measure, the overall mould design of the many employings of the middle-size and small-size design of forging die of tradition, large-scale forging die adopts die sleeve to add the method for designing of integral mould core more, because mold materials is valuable and manufacturing expense is expensive, limit its application thereby increased to a certain extent cost.Especially patrix, with compared with the mould of deep-draw head, adopts global design meeting greatly to increase the input of mold materials and expend a large amount of machining.During due to forge die, temperature can reach 480 DEG C, and internal pressure is very large, conventionally can reach 30Kg/mm
2, concerning mould itself, condition of work is very severe, therefore require mould at high temperature to have good intensity, toughness and have scientific and reasonable structural design, otherwise mould is easy to distortion and scraps even cracking.
Utility model content
For above-mentioned prior art, the utility model aims to provide a kind of detachable upper punch mould, and this mould can be saved expensive die cost, realizes the quick conversion between products of different specifications, thereby reaches the object that reduces costs, improves work efficiency.
In order to achieve the above object, the technical solution of the utility model: a kind of detachable upper punch mould, comprise die sleeve, described die sleeve middle part is provided with a cavity, and described die sleeve top is also provided with a steam vent, and described steam vent and cavity are communicated with, one switch base plate is set in described cavity, one movable ram is pressed on switch base plate by fixing wedge, and described fixing wedge is fixing by penetrate respectively die sleeve compression pin from both sides, and described movable ram adopts H13 material.
Further, between described movable ram and switch base plate, be also provided with small cushion block.
Further, described compression pin is bolted on die sleeve.
Further, on described switch base plate and fixing wedge, be provided with lifting eye, described lifting eye is screwed hole.
Further, described movable ram is provided with radian at place concordant with die sleeve.
The beneficial effects of the utility model: when adopting the detachable upper punch mould of this structure, in manufacturing the part of different model different size, can save expensive die cost, realize the quick conversion between products of different specifications, thereby reach the object that reduces costs, improves work efficiency.Movable ram adopts H13 material, other parts of mould adopt 5CrNiMo material, H13 material has higher intensity and heat endurance than 5CrNiMo material, the distortion of the deformation ratio patrix that therefore movable ram produces is little a lot, and it is the contact of circular arc band tapering with being connected of patrix, therefore can ensure that movable ram can dismantle smoothly under hot state.When dismounting, first die sleeve is taken out and set level, the hold-down bolt of dismantling, outwards exits and compresses pin, hangs out successively patrix, movable ram, changes drift and counterdie and can realize the quick conversion between different size.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, 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 structural representation of the present utility model.
Fig. 2 is the structural representation of movable ram.
In figure 1, die sleeve; 2, switch base plate; 3, small cushion block; 4, steam vent; 5, fixing wedge; 6, movable ram; 7, compress pin; 8, hold-down bolt.
Detailed description of the invention
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
The detachable upper punch mould of one as shown in Figure 1-2, it is characterized in that: comprise die sleeve 1, described die sleeve 1 middle part is provided with a cavity, described die sleeve 1 top is also provided with a steam vent 4, described steam vent 4 and cavity are communicated with, and switch base plate 2, one movable ram 6 are set in described cavity and are pressed on switch base plate 2 by fixing wedge 5, described fixing wedge 5 is fixed by the compression pin 7 that penetrates respectively die sleeve from both sides, and described movable ram 6 adopts H13 material.Described movable ram 6 is provided with radian at place concordant with die sleeve 1.
In order to ensure the forming quality (not making goods produce the phenomenons such as bubble and stagnant gas starved) of goods part, the steam vent 4 arranging at die sleeve 1 top.Because movable ram 6 is pressed on switch base plate 2 by fixing wedge 5, be that movable ram 6 can be dismantled, this mode, in manufacturing the part of different model different size, can save expensive die cost, realize the quick conversion between products of different specifications, thereby reach the object that reduces costs, improves work efficiency.Movable ram 6 adopts H13 material, other parts of mould adopt 5CrNiMo material, H13 material has higher intensity and heat endurance than 5CrNiMo material, the distortion of the deformation ratio patrix that therefore movable ram 6 produces is little a lot, and it is the contact of circular arc band tapering with being connected of patrix, therefore can ensure that movable ram 6 can dismantle smoothly under hot state.When dismounting, first die sleeve 1 is taken out and set level, the hold-down bolt 8 of dismantling, outwards exits and compresses pin, hangs out successively patrix, movable ram 6, changes drift and counterdie and can realize the quick conversion between different size.
Be more preferably, between described movable ram 6 and switch base plate 2, be also provided with small cushion block 3.In order to reduce cost, between switch base plate 2 and movable ram 6, be also provided with small cushion block 3, corresponding, the material of movable ram 6 just can reduce accordingly.
Be more preferably, described compression pin is fixed on die sleeve 1 by hold-down bolt 8, on described switch base plate 2 and fixing wedge 5, is provided with lifting eye, and described lifting eye is screwed hole.That is to say, in dismounting switch base plate 2 and fixing wedge 5, first mold integral is turned over, re-use suspender and by lifting eye, switch base plate 2 and fixing wedge 5 are sling.
The technical scheme above the utility model embodiment being provided is described in detail, applied principle and the embodiment of specific case to the utility model embodiment herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in detailed description of the invention and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
