Abstract
The utility model relates to prepressing tooling equipment, and the utility model is composed of an upper mould and a lower mould, wherein, the lower mould comprises a guide sleeve, a sliding chute and a base. By utilizing the utility model, rubber metal pieces can be conveniently prepressed to integration; besides, the percent of pass of the products of the rubber metal pieces is high, damage to the rubber metal pieces can be generated, and the utility model is ideal prepressing working equipment for rubber metal.
Description
The utility model relates to a kind of for implementing the precompressed technological equipment of elastomer, is mainly used in assembling locomotive or other mechanical industry and has precompressed product.
Along with progress of science and technology and development, people find to give suitable initial pressure of rubber element (also claiming precompression) by research and practice, and its fatigue properties, stressing conditions and mechanical performance all had very big benefit.Therefore the designer is when this class flexible member of design rubber, must consider that all this point gives element a suitable pre compressed magnitude.Does but how guaranteeing that rubber element is pressed within the specified cavity intactly go? because the intensity of elastomeric material is far away from metal, and its percentage elongation is much larger than metal, add often more complicated again of cavity geometry that rubber element will be pressed into, so if it is improper to press-fit the worker in advance, will be easy to damage rubber, cause the extremely useless of product.Easy hand assembled is just leaned in press-fiting in advance in the past, and the qualification rate of its product is low, the success or not of precompressed design thus, and its key is in the design of Prepressing working.
The purpose of this utility model is in order to improve the success that precompressed design guarantees pre-die pressing product, and proposes a kind of promptly simple technology and pattern assembly that is suitable for, guaranteeing can not cause damage in the rubber layer assembling process, and the efficient height.
The implementer's case that is proposed for achieving the above object is, utilize the good characteristics of resistance against compression energy of rubber, rubber element is placed in the guide pin bushing, again by a pressure head and briquetting, rubber element slowly is pressed into sliding formwork, rubber evenly is compressed to the path of the internal diameter that is pressed into cavity, and slips in the cavity that to be pressed into, form composite component with certain precompressed amount.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
The utility model is made of patrix (1) and counterdie (2) as can be seen from accompanying drawing, it is characterized in that patrix (1) is made up of pressure head (3) and briquetting (4), pressure head (3) is concentric and install and be one with briquetting (4), and counterdie (2) is by guide pin bushing (7), sliding formwork (8) and base (10) three parts are formed, and pressure head (3) is a cylindrical barrel, briquetting (4) is "T"-shaped shape body, and the head (11) that briquetting (4) is "T"-shaped is made taper, and guide pin bushing (7) also is a column, but sliding formwork (8) is the cone that has constant slope, its gradient ratio is 1: 5 to 1: 20, and this outer base (10) is to be pressed into the column that cavity shape matches with rubber element.
Only need earlier during use rubber assembly (5,6) be positioned in the guide pin bushing (7), again briquetting (4) is put in the rubber assembly center, on put briquetting and give (3) even downward pressure of pressure head, pressure head (3) is passed to briquetting (4) with counter-force and is driven rubber assembly (5,6) enter sliding formwork (8) by guide pin bushing (7), when rubber assembly (5,6) under the effect of briquetting (4) when sliding formwork (8) glides, under the effect of sliding formwork (8) hypotenuse, rubber parts (6) will be contracted, until be pressed onto with will go into very much the cavity lowest calibre after, naturally fall in the cavity that will be pressed into, must not unload this moment, but want reducing speed, finish to press-fiting the degree of depth when exceeding cover degree of depth 10-50%, press-fiting promptly, carry out release, the rubber assembly that can obtain installing.
Claims (1)
1, Prepressing working is made of patrix (1) and counterdie (2), it is characterized in that patrix (1) is made up of pressure head (3) and briquetting (4), pressure head (3) is concentric and install and be one with briquetting (4), and counterdie (2) is by guide pin bushing (7), sliding formwork (8) and base (10) three parts are formed, and pressure head (3) is cylindric simplified, briquetting (4) is "T"-shaped dress body, and make taper at "T"-shaped head (11), and guide pin bushing (7) also is a column, but sliding formwork (8) is the cone that has constant slope, its gradient was than 1: 5 to 1: 20, and this outer base (10) is to be pressed into the column that cavity shape matches with rubber element.
