Abstract
The utility model relates to a drawing die for large-caliber bullet shells. The outer side of the drawing die is a jacket. The drawing die is characterized in that: the drawing die comprises a guide die part and a drawing die part, an annular oil storage groove and oil outlet channels connected with the annular oil storage groove are machined along the circumference of the guide die part on the surface of the guide die contacted with the drawing die part, the oil outlet channels are radially and centripetally distributed along the guide die part, an oil supply hole and an oil intake hole which are connected with the annular oil storage groove are machined in the jacket, the periphery of the drawing die part is wrapped by an annular circulating water groove for cooling, and a cooling water inlet and a cooling water outlet are machined on the jacket and connected with both ends of the annular circulating water groove. The structure of the drawing die can guarantee lubrication and cooling. Compared with the prior art, the utility model can solve the current problem that flow is overhigh during drawing, and can reduce the cost and the consumption of energy.
Description
Technical field
The utility model is a long mould of drawing of a kind of large caliber ball cartridge bullet jacket, belongs to the machine-shaping technical field of product.
Background technology
Existingly draw long equipment because need not consider that the back dashes sharp problem, flow of lubricant can be very big, lubricant (suds) plays cooling effect simultaneously, in order to adopt the pressing equipment of multiple station vertical, the work step of back needs to solve the existing excessive problem of flow in the length of drawing, because can't be processed.
Summary of the invention
The utility model designs at above-mentioned the deficiencies in the prior art just long mould of drawing of a kind of large caliber ball cartridge bullet jacket is provided, its objective is to overcome the problem that need make in a large number in a large number in the existing processing with lubricator, satisfy the requirement of multi-station processing equipment.
The purpose of this utility model is achieved through the following technical solutions:
This kind large caliber ball cartridge bullet jacket draw long mould, its outside is an overcoat, it is characterized in that: this draws long mould and comprises the guiding mould and draw long mould composition, the guiding mould with draw on the contact-making surface of long mould, periphery along the guiding mould is processed with annular oil storage tank and the oil duct that goes out that is connected annular oil storage tank, fuel-displaced bank guiding mould radially, entad distribute, in overcoat, be processed with the oil transportation hole and the fuel feed hole that connect annular oil storage tank, be coated with the annular circulating water chennel that is used to cool off in the periphery of drawing long mould, and be processed with cooling water on the coat and advance, outlet connects the two ends of annular circulating water chennel.This kind draws the die structure and can guarantee lubricated and cooling.
The utility model has the advantages that:
(1) drawing long mould is combination die, and overcoat is an alloy tool steel as overcoat, and interior tungsten carbide button is with the guiding mould and draw long mould, is steel alloy.
(2) mould is cooled with circulating water, and cooling circulating water has been made in has drawn in the middle of long mould and the overcoat, and water is entered by water inlet, is flowed out by delivery port then in one week of mould around drawing, and takes away heat.
(3) standard multiple site punching equipment does not all have to carry out specialized designs for the bullet jacket punching press separately, do not place the space structure of guiding mould, poor for improving the quality of products, guarantee wall thickness, designed the guiding mould and be pressed onto in the overcoat overcoat, also guaranteed guiding mould and the axiality of drawing long mould simultaneously with drawing long mould.
(4) designed lubrication system, annular oil storage tank is made in the bottom with the overcoat contact-making surface at the guiding mould, the guiding mould with draw long mould contact-making surface and make many and radially go out oil duct, lubricating oil just enters annular oil storage tank by the outer passing hole channel of mould like this, directly flow to mould inside by oil duct again, promptly satisfy the requirement of the flow and the lubricated uniformity, also saved lubricating oil.

The specific embodiment
Below with reference to drawings and Examples the utility model is further described:
Shown in accompanying drawing 1～2, this kind large caliber ball cartridge bullet jacket draw long mould, its outside is an overcoat 1, it is characterized in that: this draws long mould and comprises guiding mould 2 and draw long mould 3 compositions, guiding mould 2 with draw on the contact-making surface of long mould 3, along the periphery of guiding mould 2 be processed with annular oil storage tank 4 be connected annular oil storage tank 4 go out oil duct 5, go out oil duct 5 radially along guiding mould 2, entad distribute, in overcoat 1, be processed with the oil transportation hole 6 and the fuel feed hole 7 that connect annular oil storage tank 4, be coated with the annular circulating water chennel 8 that is used to cool off in the periphery of drawing long mould 3, and on overcoat 1, be processed with cooling water and advance, outlet 9,10 connect the two ends of annular circulating water chennel 8.
The lubricating oil employing trade mark is 32 to 64 steam turbine oil or L-AN total loss system oil, or rapeseed oil.
Compared with prior art, the utility model mould can solve the existing excessive problem of flow in the length of drawing, and reduces cost and energy consumption.
