Abstract

The utility model discloses a punching device for a battery shell. The punching device comprises a puncher, a concave mould and a concave mould frame, wherein the concave mould is arranged in a slot at the top of the concave mould frame; mould cavities are concentrically formed on the concave mould and the concave mould frame; an annular slot is arranged on an external circle of the puncher; an elastic O-shaped ring is arranged in the annular slot; and a tapered opening is arranged at the top of the concave mould. The annular slot is arranged on the external circle of the puncher and the elastic O-shaped ring is arranged in the annular slot; when the puncher descends, the elastic O-shaped ring is plugged into a tapered horn opening on an inlet part; the elasticity of the elastic O-shaped ring is utilized to tightly support cut waste materials, so as to ensure that the waste materials are efficiently extracted by the puncher; and compared with the prior art, the punching device has the advantages that the extracting problem of the waste materials is efficiently solved, the mould is prevented from being damaged, the service life of the mould is prolonged, the structure is simple and the practicability is stronger.

Description

A kind of battery case decompressor

Technical field

The utility model relates to a kind of battery case decompressor, relates in particular to a kind of waste material that can prevent and extracts the battery case decompressor that lost efficacy.

Background technology

Battery refers to fill electrolyte solution and the metal electrode segment space with the cup, groove or other containers or the clad vessel that produce electric current.Along with the progress of science and technology, the battery general reference can produce the midget plant of electric energy.The kind of battery is a lot, and battery commonly used mainly is dry cell, battery, and the little minicell of volume or the like.But owing to contain heavy metal noxious materials such as mercury, cadmium, lead, zinc in the battery; The people is if directly this type of heavy metal of contact can cause very big injury to human body; So battery case also accounts for considerable position in battery; Both can the material in the battery be held, can also noxious material and people be separated.

Battery case need cut the waste material of oral area behind drawing and forming, and is as shown in Figure 3, and conventional battery shell decompressor mainly comprises drift and die; Drift descends, through with the extruding of die, the oral area waste material is cut off, and continues the battery case that cuts is delivered to downwards below the die lower surface; Drift gos up then, relies on the lower plane of die to stop, battery case is unloaded from drift, falls in the following finished product frame; The waste material of excision then need be stayed on the drift, forward the waste product district then to and handle, yet in actual production, waste material is stayed on the drift and is extracted by drift; Often receive the performance of material, the factor affecting such as surface roughness of drift, be easy to cause inefficacy, in case lost efficacy; Waste material can not in time be removed and stay on the die upper surface, and mould is broken down, and heavy then mould wracks.

The utility model content

The purpose of the utility model is to address the above problem, and a kind of battery case decompressor is provided, and it can effectively extract the waste material in the punching course, has protected the integrality of mould, has made things convenient for use.

The purpose of the utility model is to realize through following technical scheme:

A kind of battery case decompressor comprises drift, die, die frame, and die places in the groove of die arch; Die, die frame are concentric has die cavity; Said drift outer ring is provided with annular groove, and said inside grooves is provided with elasticity O type circle, and the top of die is provided with bell.

The aperture of said die frame die cavity is slightly larger than the aperture of die die cavity.

Said die is the carbide alloy die.

The center of the bell that the center of said die die cavity, die top are provided with is on same straight line.

The beneficial effect of the utility model is: through in the drift outer ring one annular groove being set, be provided with elasticity O type circle in the groove, when drift was descended, elasticity O type circle was just filled in the conical horn mouth of oral area; Lean on the elasticity of elasticity O type circle, the waste material that downcuts is tightly propped up, thereby guarantee effectively to be extracted by drift; The contrast prior art, this device can effectively solve the extraction problem of waste material, prevents the damage of mould; Prolong the service life of mould, and simple in structure, practicality is stronger.

Description of drawings

According to accompanying drawing and embodiment the utility model is done further explain below.

Fig. 1 is the cross-sectional schematic of the described a kind of battery case decompressor of the utility model;

Fig. 2 is that the A shown in Fig. 1 is to enlarged diagram;

Fig. 3 is the cross-sectional schematic of former decompressor.

Among the figure:

1, die frame; 2, die; 3, elasticity O type circle; 4, drift; 5, waste material; 6, battery case.

The specific embodiment

Among the embodiment as illustrated in fig. 1 and 2, the described a kind of battery case decompressor of the utility model comprises drift 4, carbide alloy die 2, die frame 1; Die 2 places in the groove at die frame 1 top; Die 2, die frame 1 are concentric has die cavity, and drift 4 outer rings are provided with annular groove, and inside grooves is provided with elasticity O type circle 3; The top of die 2 is provided with bell; And the center of bell and die 2 die cavity centers are on same straight line, and 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 behind drawing and forming, and drift 4 descends, through with the extruding of die 2, oral area waste material 5 is cut off; And continue the battery case that cuts 6 is delivered to downwards below die 2 lower surfaces, drift 4 gos up then, relies on the lower surface of die 2 to stop, battery case 6 is unloaded from drift 4; Fall in the following finished product frame, and the waste material 5 of excision is stayed on the drift 4 by the propping up tightly of the elasticity O type circle 3 on the drift 4; Extracted by drift 4, move to the waste material frame, be blown in the waste material frame with compressed air.

Claims

1. battery case decompressor; Comprise drift, die, die frame, die places in the groove of die arch, and die, die frame are concentric has die cavity; It is characterized in that; Said drift outer ring is provided with annular groove, and said inside grooves is provided with elasticity O type circle, and the top of die is provided with bell.
