Abstract

The invention discloses a kind of cup drawing diel, the upper die and lower die being correspondingly arranged including above and below, the upper mould includes upper bolster, punch retainer and punch-pin successively, the lower mould includes cavity plate, die block and die shoe successively, and blank holder is installed with the upper transverse plane of the cavity plate, the punch-pin is in cylinder, and the cavity plate is in the cylindrical shape being engaged with the punch-pin, offered in the middle part of the punch-pin in cavity, the cavity and electric heating tube is installed.By the above-mentioned means, it is of the invention, it is simple in construction, blank holder is used during cylinder drawing, the compression of blank peripheral direction during drawing process can be prevented and make product bottom bending phenomenon occurs, it is ensured that product high yield rate, electric heating tube, punch forming efficiency high are provided with punch-pin simultaneously.

Description

A kind of cup drawing diel

Technical field

The present invention relates to technical field of mold, more particularly to a kind of cup drawing diel.

Background technology

The important component of drawing mould includes punch-pin, cavity plate and location-plate, when from blank drawing process drum, Blank is placed on location-plate, blank is carried out after drawing using punch-pin, product is dropped down onto lower section, mold structure by cavity plate Simply, but found in long-term use, it has the disadvantage that product bottom easily bends, and product product qualified rate is low.

The content of the invention

It is simple in construction the present invention solves the technical problem of a kind of cup drawing diel is provided, during cylinder drawing Using blank holder, the compression of blank peripheral direction during drawing process can be prevented and make product bottom bending phenomenon occurs, Product high yield rate is ensured, while being provided with electric heating tube, punch forming efficiency high in punch-pin.

In order to solve the above technical problems, one aspect of the present invention is:A kind of cup drawing stamping die is provided Tool, including the upper die and lower die being correspondingly arranged up and down, the upper mould include upper bolster, punch retainer and punch-pin successively, described Lower mould includes being installed with blank holder on cavity plate, die block and die shoe, and the upper transverse plane of the cavity plate successively, The punch-pin is in cylinder, and the cavity plate is in offer cavity in the middle part of the cylindrical shape being engaged with the punch-pin, the punch-pin, Electric heating tube is installed in the cavity.

In a preferred embodiment of the present invention, the blank holder is rounded, and its middle part offers cylinder edge formed body.

In a preferred embodiment of the present invention, the cylinder edge formed body is two symmetrical arc surfaces.

In a preferred embodiment of the present invention, the upper end of the upper bolster is integrally formed with die shank.

The beneficial effects of the invention are as follows:The present invention on the upper transverse plane of cavity plate by being provided with blank holder, in cylinder drawing While use blank holder, the compression of blank peripheral direction during drawing process can be prevented, thus avoid product bottom send out Raw buckling phenomenon, it is ensured that product high yield rate, while being provided with electric heating tube, punch forming efficiency high in punch-pin.

Brief description of the drawings

Fig. 1 is the structural representation that a kind of cambered surface of the invention is integrally formed die cutting die;

The mark of each part is as follows in accompanying drawing:1st, upper mould, 2, lower mould, 3, blank holder, 4, electric heating tube, 11, upper bolster, 12, convex Mould fixed plate, 13, punch-pin, 14, die shank, 21, cavity plate, 22, die block, 23, die shoe, 31, cylinder edge formed body.

Embodiment

Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.

Referring to Fig. 1 embodiment of the present invention includes:

A kind of cup drawing diel, including the upper mould 1 and lower mould 2 installed are corresponded to up and down, the upper mould 1 includes upper mould successively Seat 11, punch retainer 12 and punch-pin 13, the lower mould 2 include cavity plate 21, die block 22 and die shoe 23 successively, and Be installed with blank holder 3 on the upper transverse plane of the cavity plate 21, the punch-pin 13 in cylinder, the cavity plate 21 be in it is described The cylindrical shape that punch-pin 13 is engaged, the middle part of the punch-pin 13, which is offered in cavity, the cavity, is provided with electric heating tube 4, energy Enough improve punch forming efficiency.

Wherein, the blank holder 3 is rounded, and its middle part offers cylinder edge formed body 31, the cylinder edge shaping Body 31 is two symmetrical arc surfaces, for cylinder edge shaping.

Preferably, process operation is easy in the upper end of the upper bolster 11 integrally formed with die shank 14.

During work, on the blank holder 3 that blank is placed in the top of cavity plate 21, punch-pin 13 is moved down blank drawing and forming, The edge punching molding of cylinder, the in addition electric heating tube 4 positioned at the middle part of punch-pin 13 can be improved drawing and forming effect by blank holder 3 simultaneously Rate.

The invention provides a kind of cup drawing diel, by being provided with blank holder on the upper transverse plane of cavity plate, Blank holder is used while cylinder drawing, the compression of blank peripheral direction during drawing process can be prevented, so as to avoid system Bending phenomenon occurs for part bottom, it is ensured that product high yield rate, while being provided with electric heating tube, punch forming efficiency high in punch-pin.

Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills Art field, is included within the scope of the present invention.
