Abstract
The utility model relates to a special stretching device arranged in a press machine. An upper mould of a mould is composed of a piece of polyaminoresin, and a lower mould is composed of a left and a right half parts which are made of metal. The mould improves complicated processes of manufacturing an oil tank casing, leaves out the welding process of the casing, and heightens the surface smoothness and the quality of the oil tank casing; the mould can also manufacture irregular-shaped oil tank casings which are greater than semicircles, and the irregular-shaped oil tank casings can be one-step integrally formed. The utility model which has the advantages of convenient operation and high work efficiency is an ideal mould for manufacturing various oil tank casings, particularly the irregular-shaped oil tank casings which are greater than the semicircles.
Description
The utility model relates to the special stretching device that is disposed in the forcing press, is a kind of mould of making fuel tank shell.
At present, the mould of manufacturing fuel tank shell all is with metal.Make shape comparatively complicated, particularly to the time greater than the fuel tank shell of the non-regular shape of semicircle, often adopt and overpay mould and divide several procedures to create.Complex-shaped fuel tank shell must become left and right two parts by several pairs of Mould Machining, and then is welded into a complete fuel tank shell.The example that is fabricated to present domestic advanced " happy 250C " motorcycle oil tank shell: first pair of stretching die is pressed into certain hull shape to material.Second pair of shaving die is unnecessary four limits excision.The Third Mate cuts two mould, and the excision of housing semi-finished product two bossing, the 4th pair of side cut concora crush muscle mould is the further integer of housing.The 5th pair is cut mould, and the left and right two halves that connects together is cut.Be welded into a complete fuel tank shell with the left and right two halves of some electrode holder more at last.Make the operation more complicated of fuel tank shell like this.How operation causes raw-material waste, labour's waste again.The speed that manufactures a product is slow, and quality is also poor, and the fineness of welding portion is poor, and oil leakage phenomenon also takes place sometimes.
The purpose of this utility model is to provide a kind of new fuel tank mould, with the manufacturing procedure of minimizing fuel tank, and economical with materials, the power that lightens one's labor becomes the moulding several times of the left and right two halves of separating Integratively formed.Save welding sequence, improve the surface smoothness of fuel tank shell, overcome oil leakage phenomenon.
The purpose of this utility model realizes that by following method mould is made up of upper and lower mould, and counterdie divides left and right two parts again.Patrix is with there being the polyamino resin rubber of retractility to make, left and right two halves counterdie is made with mould steel, its inner chamber has the profile lines of fuel tank, add and man-hour steel plate is put into counterdie downforce machine patrix is depressed, because polyamino resin rubber can be out of shape arbitrarily, just steel plate is squeezed in the inner chamber of counterdie, and has been full of whole fuel tank inner chamber, mention patrix again and separate left and right two counterdies, just a press forming of fuel tank.Left and right two parts are processed because counterdie is a branch, and therefore the curvature of its shape can suppress the non-regular die cavity greater than semicircle greater than 180 °.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the state of mould when starting working.
Fig. 2 is the state of mould when carrying out the work matched moulds.
Fig. 3 is the state of mold work when finishing molding.
(1) is the four-column type universal hydraulic machine among the figure.
(2) be the counterdie left-half.
(3) be fuel tank shell.
(4) be patrix.
(5) be cushion block.
(6) be stage clip.
(7) be pressing plate.
(8) be the counterdie right half part.
This mould with polyamino resin rubber a little the worker make simple shape, just can be made into the patrix of mould. Patrix can be fixed on the top mold frame with cushion block, also can directly be fixed on the top of hydraulic press. Counterdie 2, the 8th, separate machined, a whole die cavity become altogether. Counterdie 2,8 can be placed on lower mold holder, also can be placed directly on the workbench of hydraulic press. Stage clip 6, pressing plate 7 all are attached to the patrix mould bases, also can be contained in the top of hydraulic press, be used for fixing fuel tank shell, i.e. processing work 3.
Specific embodiment of the utility model: (3) fuel tank shell is put into counterdie 2,8.Patrix 4 moves down.When hydraulic press 1 is extruded patrix 4 downwards,, fuel tank shell is squeezed into the shape of counterdie 2,8 inner chambers in counterdie because polyamino resin rubber expands to all directions.So just finished the pressing process of fuel tank.The hydraulic press beginning molding that moves up this moment, the oil pump on the hydraulic press is the left-half horizontal open of counterdie simultaneously, and the fuel tank shell of forming can take out from mould.
The utility model can be made can be Integratively formed greater than the housing ， And of the irregular shape of semicircle. Or else need fuel tank shell is divided into and weld again after left and right two halves is processed respectively. Reduce a lot of operations, saved welding sequence, improved the surface smoothness of fuel tank shell, overcome oil leakage phenomenon.
The utility model is applicable to the moulding of various automotive oil tank shells.
Characteristics of the present utility model are simple in structure, and are easy to use, and patrix is made by a polyamino resin rubber. Polyamino resin rubber can be made arbitrarily needed simple shape. Counterdie is that the left and right two halves that is made of metal forms. Even complicated die cavity is processed also very convenient. Two halves is removable, is convenient to take out the workpiece of making, and mould can use at all kinds of hydraulic presses.
Claims (3)
1, fuel tank shaping mould, it is made up of upper and lower mould, it is characterized in that patrix is to be made by a polyamino resin rubber, and described counterdie is made by mould steel, and is made up of left and right two parts.
2, according to the said fuel tank shaping mould of claim 1, it is characterized in that polyamino resin rubber makes certain simple shape as required.
3, according to the said fuel tank shaping mould of claim 1, the counterdie die cavity that it is characterized in that being divided into two parts makes the die cavity greater than semicircle.
