Abstract
The present invention discloses a kind of drawing die, comprises die socket and is arranged at the die in die socket, described die socket has cooling duct.Described drawing die sets up cooling duct on die socket, thus can carry out pressure cooling to die socket, and by being equipped with cooling-water machine; the temperature of cooling water is reduced, further enhances cooling effect, by adopting the die socket of this kind of structure; when temperature 35 DEG C; the temperature of die socket is only 20 ~ 25 DEG C, considerably reduces die temperature, improves the depositional phenomenon of built-up edge greatly; decrease shutdown to repair a die number of times; extend uninterrupted working time, improve production efficiency, add output.
Description
Technical field
The present invention relates to a kind of drawing die.
Background technology
Battery steel shell is by the shaping stamping parts of multi-drawing with thin plate.As shown in Figure 1, for existing for the drawing die of the box hat that stretches, it comprises die socket 11 and die 12, in drawing process, the die 12 of drawing die, owing to subject huge extruding force and sliding friction fast always, can produce a large amount of heats, particularly at the oral area of die 12 active section.Although whole process has drawing oil to lubricate, but the high temperature that the oral area of die 12 produces when stretching, sharply can worsen box hat and pass through lubrication environment and the lubricant effect of this section moment, time one is long, from the fine particle that box hat surfacial spalling is got off, built-up edge 13 will be gathered at the oral area of die 12, the built-up edge 13 of this attachment is very firmly with the combination of die 12, die 12 must be pulled down again grind and could remove, if removed not in time, " wire drawing " phenomenon will be produced on box hat surface, cause box hat to scrap.
Above-mentioned phenomenon is not also clearly when temperature is lower in the winter time, because environment temperature is low, and drawing die rapid heat dissipation; But arrived summer temperature higher time, situation is just very bad, because heat radiation is slow; the die socket 11 of die 12 itself have accumulated a large amount of heats; the high temperature of die 12 oral area is with regard to more difficult conduction and distribute, so often can produce built-up edge 13, brings great impact to production.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of drawing die is provided, in use easily produce built-up edge to solve existing drawing die, affect box hat quality, reduce the problem of production efficiency.
The object of the invention is to be achieved through the following technical solutions:
A kind of drawing die, comprises die socket and is arranged at the die in die socket, described die socket has cooling duct.
Further, described cooling duct is arranged at the circumferential perimeter place of die.
Preferably, described cooling duct is arranged at the circumferential perimeter place of die oral area.
Further, described cooling duct comprises the feed tube, the drain pipe that are parallel to each other, one end of described feed tube has inlet, the other end was connected with communicating pipe, one end of described drain pipe has liquid outlet, the other end was connected with communicating pipe, and described communicating pipe and feed tube, drain pipe are perpendicular, and the two ends of communicating pipe are provided with silently.
Preferably, described liquid outlet connects water tank, and described water tank is connected with pump, and described pump is connected with cooling-water machine, and described cooling-water machine is connected with inlet.
Beneficial effect of the present invention is; described drawing die sets up cooling duct on die socket; thus pressure cooling can be carried out to die socket; and by being equipped with cooling-water machine; the temperature of cooling water is reduced; further enhance cooling effect; by adopting the die socket of this kind of structure, when temperature 35 DEG C, the temperature of die socket is only 20 ~ 25 DEG C; considerably reduce die temperature; improve the depositional phenomenon of built-up edge greatly, decrease shutdown and to repair a die number of times, extend uninterrupted working time; improve production efficiency, add output.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Please refer to shown in Fig. 2 and Fig. 3, Fig. 2 is the structural representation of a kind of drawing die of the present invention; Fig. 3 is the cross-sectional schematic of a kind of drawing die at A-A place shown in Fig. 2.In the present embodiment, a kind of drawing die, comprise die socket 21 and be arranged at the die 22 in die socket 21, described die socket 21 has cooling duct 23, described cooling duct 23 is arranged at the circumferential perimeter place of die 22 oral area, and described cooling duct 23 comprises the feed tube 231 be parallel to each other, drain pipe 233, one end of described feed tube 231 has inlet 234, the other end was connected with communicating pipe 232, one end of described drain pipe 233 has liquid outlet 235, the other end was connected with communicating pipe 232, described communicating pipe 232 and feed tube 231, drain pipe 233 is perpendicular, and the two ends of communicating pipe 232 are provided with silently 236, described liquid outlet 235 connects water tank, described water tank is connected with pump, described pump is connected with cooling-water machine, described cooling-water machine is connected with inlet 234.
The present invention is in drawing process; by pump, cooling water is circulated in cooling duct 23; pressure cooling is carried out to die socket 21; and by arranging cooling-water machine, making the temperature of cooling water below 10 DEG C, further enhancing cooling effect; thus improve the depositional phenomenon of built-up edge greatly; decrease shutdown to repair a die number of times, extend uninterrupted working time, improve production efficiency.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
