Abstract
The invention discloses a die structure specially used for processing an integral glass fiber reinforced plastic flange. The die structure comprises a glass fiber reinforced plastic flange, a guide rod, a die seat, a core shaft, a press block and a positioning sleeve, wherein the glass fiber reinforced plastic flange is arranged in a cavity formed by the press block and the die seat; the die seat is arranged at the bottom part of the glass fiber reinforced plastic flange; the press block is arranged at the top part of the glass fiber reinforced plastic flange; the core shaft is connected with the die seat; the press block and the die seat are provided with bolt holes; the guide rod is arranged in the bolt holes and used to fix and connect the press block and the die seat; the exterior of the die seat is surrounded by the positioning sleeve; the top part of the positioning sleeve is contacted with the bottom part of the press block; and the glass fiber reinforced plastic flange comprises a flange drum body and a flange ring. The die structure specially used for processing the integral glass fiber reinforced plastic flange provided by the invention has simple structure, can greatly reduce local stress concentration and oversize deformation of the flange due to an unreasonable structure, and improves the strength and rigidity of the integral glass fiber reinforced plastic flange.
Description
Technical field
The present invention relates to a kind of mould structure being specifically designed to processing whole glass steel flange, belong to flange processing technique field.
Background technology
Flange uses the widest detachable connection part in pipeline and container, and along with GRP pipe, container use increasingly extensive, the performance of glass fiber reinforced plastic flange and making also comes into one's own gradually.Conventional glass fiber reinforced plastic flange is used for mesolow hydraulic piping, the container that pressure is not more than 3MPa, and primary structure is formed with integral (type) flange, bonding flange and lap joint flange.
Integral (type) flange such as to be generally at the wall thickness flat flange.The advantage of this structure is that flange ring and cylindrical shell are monolithic molding, reinforcing glass fiber and fabric are continuous print, can give full play to the characteristic of high, the easy shaping of fiberglass intensity, its shortcoming waits wall thickness structure to distribute with flange internal stress not mate, be difficult to realize equal strength, etc. rigidity Design requirement; In using, easily there is moderate finite deformation in flange ring and cylindrical shell junction, even occur micro-crack and cracking destruction under longitudinal stress effect.
Summary of the invention
The object of the present invention is to provide a kind of mould structure being specifically designed to processing whole glass steel flange, solve flange stress concentration and micro-crack and cracking destruction.
The present invention adopts following technical scheme: a kind of mould structure being specifically designed to processing whole glass steel flange, it is characterized in that, comprise glass fiber reinforced plastic flange, guide pillar, die holder, mandrel, briquetting, positioning sleeve, described glass fiber reinforced plastic flange is arranged in the cavity that described briquetting and described die holder formed, described die holder is arranged at the bottom of described glass fiber reinforced plastic flange, described briquetting is arranged at the top of described glass fiber reinforced plastic flange, described mandrel is connected with described die holder, described briquetting and described die holder all have bolt hole, described guide pillar is arranged in described bolt hole, be used for fixing and be connected described briquetting and described die holder, the outside of described die holder is also surrounded with positioning sleeve, the top of described positioning sleeve and the bottom connection of described briquetting touch, described glass fiber reinforced plastic flange comprises flange cylindrical shell, flange ring.
Preferably, the external diameter of mandrel is equal with the internal diameter of glass fiber reinforced plastic flange.
Preferably, the external diameter of die holder is equal with the external diameter of glass fiber reinforced plastic flange.
Preferably, the diameter of guide pillar is equal with the diameter of bolt hole.
Preferably, to deduct the thickness of die holder equal with the thickness of the flange ring of glass fiber reinforced plastic flange for the height of positioning sleeve.
Preferably, the number of briquetting is 2 ~ 4.
The beneficial effect that the present invention reaches: greatly can reduce stress raisers that flange occurs due to unreasonable structure and distortion excessive, improve the strength and stiffness of whole glass steel flange.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication marked in figure: 1-guide pillar, 2-die holder, 3-mandrel, 4-glass fiber reinforced plastic flange, 5-briquetting, 6-positioning sleeve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1 be structural representation of the present invention, the present invention proposes a kind of mould structure being specifically designed to processing whole glass steel flange, comprise glass fiber reinforced plastic flange 4, guide pillar 1, die holder 2, mandrel 3, briquetting 5, positioning sleeve 6, glass fiber reinforced plastic flange 4 is arranged in the cavity that briquetting 5 and die holder 2 formed, die holder 2 is arranged at the bottom of glass fiber reinforced plastic flange 4, briquetting 5 is arranged at the top of glass fiber reinforced plastic flange 4, mandrel 3 is connected with die holder 2, briquetting 5 and die holder 2 all have bolt hole, guide pillar 1 is arranged in described bolt hole, be used for fixing and be connected briquetting 5 and die holder 2, the outside of die holder 2 is also surrounded with positioning sleeve 6, the top of positioning sleeve 6 and the bottom connection of briquetting 5 touch, glass fiber reinforced plastic flange 4 comprises flange cylindrical shell, flange ring.
The external diameter of mandrel 3 is equal with the internal diameter of glass fiber reinforced plastic flange 4; The external diameter of die holder 2 is equal with the external diameter of glass fiber reinforced plastic flange 4; The diameter of guide pillar 1 is equal with the diameter of bolt hole; The thickness that the height of positioning sleeve 6 deducts die holder 2 is equal with the thickness of the flange ring of glass fiber reinforced plastic flange 4; The number of briquetting 5 is 2 ~ 4.
The beneficial effect that the present invention reaches: greatly can reduce stress raisers that flange occurs due to unreasonable structure and distortion excessive, improve the strength and stiffness of whole glass steel flange.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
