Abstract

The utility model belongs to the technical field of a dry battery manufacturing device and in particular relates to a die punching device used for manufacturing dry battery carbon cakes, comprising a hollow die punching body; a hollow ceramic tube is embedded in the hollow position of the die punching body; the ceramic tube not only has good acid resistant, alkaline-resisting and corrosion resistant functions, but also has good wear-resisting property, thus leading the die punching body to have long service life; the die punching body is not needed to be frequently replaced, thus reducing the production cost.

Description

A kind ofly make the die set that dry cell carbon cake is used

Technical field:

The utility model belongs to dry cell manufacturing installation technical field, particularly a kind ofly makes the die set that dry cell carbon cake is used.

Background technology:

The die set of present manufacturing dry cell carbon cake is seen accompanying drawing 1, generally comprises the punch die body 1 of hollow, and punch die body 1 is generally metallic object, pours carbon dust the middle vacancy of punch die body 1 into, strikes out ring-type carbon cake with the drift that cooperates with it.Usually be added with various auxiliary agents in the carbon dust, the punch die body 1 of their corroding metals makes that punch die body 1 is impaired.And carbon dust and the 1 frequent high pressure friction of punch die body in the punching production process, punch die body 1 weares and teares easily, and wearing and tearing backlash mould body 1 needs to change the production cost height.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, and the die set that provides a kind of wear-resisting manufacturing dry cell carbon cake to use.

For achieving the above object, the utility model adopts following technical scheme:

A kind ofly make the die set that dry cell carbon cake is used, comprise the punch die body of hollow, be inlaid with the earthenware of hollow in the middle vacancy of punch die body.

Described punch die body is cylindric.

Described punch die body is round table-like.

Described earthenware is identical with the punch die body height.

The utility model beneficial effect is: the utility model comprises the punch die body of hollow, be inlaid with the earthenware of hollow in the middle vacancy of punch die body, earthenware not only has well acidproof, alkaline-resisting, corrosion resistant function, and has an anti-wear performance preferably, make the punch die body have long useful life, do not need often to change the punch die body, reduce production costs.

Description of drawings:

Fig. 1 is a prior art punch die main body structure schematic diagram;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the structural representation of the utility model earthenware.

Embodiment:

In order to further describe the utility model, illustrate with specific embodiment below in conjunction with accompanying drawing:

See Fig. 2-3, a kind ofly make the die set that dry cell carbon cake is used, the punch die body 1 that comprises hollow, be inlaid with the earthenware 2 of hollow in the middle vacancy of punch die body 1, earthenware 2 has well acidproof, alkaline-resisting, corrosion resistant function, even often change the auxiliary agent kind that is added in the carbon dust, punch die body 1 can not be corroded yet, and is durable in use.Earthenware 2 also has anti-wear performance preferably, makes punch die body 1 have long useful life, does not need often to change punch die body 1, reduces production costs.During use, pour carbon dust the middle vacancy of the earthenware 2 of hollow into, the drift punching press from top to bottom with cooperating with it strikes out ring-type carbon cake with carbon dust.

Described punch die body 1 is cylindric, punch die body 1 is made cylindricly can be born bigger stamping press.

Described punch die body 1 is round table-like, can bear bigger stamping press, and conveniently ejects the good carbon cake of punching press.

Described earthenware 2 is highly identical with punch die body 1, and when adding carbon dust, carbon dust is not easy to spread out, and is easy to use.

Certainly, the embodiment of the above, it is better embodiment of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
