Abstract

The invention discloses a battery shell stamping device which comprises a punch, a female die and a female die frame, wherein the female die is arranged in a groove at the top of the female die frame; the female die and the female die frame are concentrically provided with a die cavity; an annular groove is arranged on the outer ring of the punch; an elastic O-shaped ring is arranged in the groove; and a conical opening is arranged at the top of the female die. As the annular groove is arranged on the outer ring of the punch and the elastic O-shaped ring is arranged in the groove, when the punch goes down, the elastic O-shaped ring can be exactly plugged in the conical bell opening of the mouth part; and under the elasticity of the elastic O-shaped ring, the cut waste material is firmly supported and can be effectively extracted by the punch for sure. Compared with the prior art, the device can effectively solve the problem of the extraction of the waste material, prevent the damage of the die and prolong the service life of the die, and has a simple structure and higher practicability.

Description

A kind of battery shell stamping device
Technical field
The present invention relates to a kind of battery shell stamping device, relate in particular to a kind of battery shell stamping device that can prevent that waste material extraction was lost efficacy.
Background technology
Battery refers to fill electrolyte solution and the metal electrode segment space with cup, groove or other containers or the clad vessel of generation current.Along with scientific and technological progress, battery general reference can produce the midget plant of electric energy.The kind of battery is a lot, and conventional battery is mainly dry cell, battery, and the little minicell of volume etc.But owing to containing the heavy metal noxious materials such as mercury, cadmium, lead, zinc in battery, if directly contacting this type of heavy metal, people can cause very large injury to human body, so battery case also accounts for considerable position in battery, both the material in battery can be held, noxious material and people can also be separated.
Battery case is after drawing and forming, the waste material of oral area need to be cut, as shown in Figure 3, existing battery shell stamping device mainly comprises drift and die, drift declines, by with the extruding of die, oral area waste material is cut off, and continue the battery case cutting to deliver to below die lower surface downwards, then drift gos up, rely on the lower plane of die to stop, battery case is unloaded from drift, fall in finished product frame below, the waste material of excision needs to stay on drift, then forwarding waste product district to processes, but in actual production, waste material is stayed on drift and is extracted by drift, often be subject to the performance of material, the factor impacts such as the surface roughness of drift, be easy to cause inefficacy, once lose efficacy, waste material can not be removed in time and stay on die upper surface, gently make mould break down, heavy mould wracks.
Summary of the invention
The object of the invention is to address the above problem, a kind of battery shell stamping device is provided, it can effectively extract the waste material in punching course, has protected the integrality of mould, has facilitated use.
The object of the invention is to be achieved through the following technical solutions:
A kind of battery shell stamping device, comprises drift, die, die frame, and die is placed in the groove of die arch, what die, die frame were concentric has die cavity, described drift outer ring is provided with annular groove, and described inside grooves arranges elasticity O type circle, and the top of die arranges bell.
The aperture of described die frame die cavity is slightly larger than the aperture of die die cavity.
Described die is carbide matrix.
The center of the center of described die die cavity, the bell that die top arranges is on same straight line.
Beneficial effect of the present invention is: by one annular groove being set in drift outer ring, be provided with elasticity O type circle in groove, when drift is declined, elasticity O type circle is just filled in the conical horn mouth of oral area, by the elasticity of elasticity O type circle, the waste material cutting is tightly propped up, thereby guarantee effectively to be extracted by drift, contrast prior art, this device can effectively solve the extraction problem of waste material, prevents the damage of mould, extends the service life of mould, and simple in structure, practicality is stronger.
Brief description of the drawings
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the cross-sectional schematic of a kind of battery shell stamping device of the present invention;
Fig. 2 is that the A shown in Fig. 1 is to enlarged diagram;
Fig. 3 is the cross-sectional schematic of former decompressor.
In figure:
1, die frame; 2, die; 3, elasticity O type circle; 4, drift; 5, waste material; 6, battery case.
Detailed description of the invention
As illustrated in fig. 1 and 2 in embodiment, a kind of battery shell stamping device of the present invention, comprise drift 4, carbide matrix 2, die frame 1, die 2 is placed in the groove at die frame 1 top, what die 2, die frame 1 were concentric has die cavity, drift 4 outer rings are provided with annular groove, inside grooves arranges elasticity O type circle 3, the top of die 2 arranges bell, and the center of bell and die 2 die cavity centers are on same straight line, die frame 1 die cavity aperture is slightly larger than die 2 die cavity apertures, and the finished product of being convenient to battery case 6 rolls off the production line.
Battery case 6 is after drawing and forming, and drift 4 declines, by with the extruding of die 2, oral area waste material 5 is cut off, and continue the battery case cutting 6 to deliver to below die 2 lower surfaces downwards, then drift 4 gos up, rely on the lower surface of die 2 to stop, battery case 6 is unloaded from drift 4, fall in finished product frame below, and the waste material 5 of excision is by the propping up tightly of the elasticity O type circle 3 on drift 4, stay on drift 4, extracted by drift 4, move to waste material frame, be blown in waste material frame with compressed air.

Claims (4)
