Abstract

The invention relates to a sheet metal component punching mould belonging to the technical field of sheet metal component processing equipment. The sheet metal component punching mould comprises an upper mould plate and a lower mould plate, wherein the upper mould plate and the lower mould plate are longitudinally distributed; four guide pillars distributed in a square shape are arranged on the lower mould plate; the tops of the guide pillars penetrate through the upper mould plate and are fixed by using nuts; springs are sleeved on the guide pillars; a punching block is fixed on the upper mould plate; the top of the punching block is connected with an air cylinder, and the bottom of the punching block is provided with an L-shaped tool edge; the air cylinder and the L-shaped tool edge are respectively arranged at the upper side and the lower side of the upper mould plate; a square groove is arranged on the lower mould plate; and the L-shaped tool edge stretches into the square groove when the lower mould plate is descended. The sheet metal component punching mould has novel structural design; in the invention, the descending of the upper mould plate is controlled through the air cylinder, thereby realizing the punching operation of a sheet metal component; and the control of the descending direction of the upper mould plate is realized through the guide pillars and the springs, thereby enhancing the accuracy of punching processing.

Description

The sheet metal component blanking die

Technical field

The present invention relates to a kind of sheet metal component blanking die, belong to the sheet metal component technical field of processing equipment.

Background technology

Existing sheet metal component clicker press machine mould, structure is comparatively simple, and working (machining) efficiency is lower.

Summary of the invention

To the problems referred to above that exist in the prior art, the invention provides the high sheet metal component blanking die of a kind of working (machining) efficiency.

The technical scheme that the present invention adopts is following:

The sheet metal component blanking die is characterized in that, has to be the cope match-plate pattern and the lower bolster of vertically arranging,

Lower bolster is provided with four guide pillars that are square and arrange, and the guide pillar top is passed cope match-plate pattern and fixed with nut, is with spring on the guide pillar;

Cope match-plate pattern is fixed with the stamping-out piece, and stamping-out piece top connects cylinder, and the bottom is provided with the L shaped edge of a knife, and the cylinder and the L shaped edge of a knife place the upper and lower side of cope match-plate pattern respectively;

Lower bolster is provided with square groove, and the L shaped edge of a knife stretched in the square groove when cope match-plate pattern fell.

Sheet metal component blanking die of the present invention, structural design is novel, through the whereabouts of cylinder control cope match-plate pattern, realizes the stamping-out operation to sheet metal component.Simultaneously,, realize the falling direction of cope match-plate pattern is controlled, thereby improved the precision of stamping-out processing through guide pillar and spring.

Description of drawings

For the ease of it will be appreciated by those skilled in the art that invention is further described below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present invention.

The specific embodiment

See also Fig. 1, the sheet metal component blanking die has and is cope match-plate pattern of vertically arranging 3 and lower bolster 6.

Lower bolster 6 is provided with four guide pillars 4 that are square and arrange, and guide pillar 4 tops are passed cope match-plate pattern 3 and fixed with nut, are with spring 8 on the guide pillar 4.

Cope match-plate pattern 3 is fixed with stamping-out piece 2, and stamping-out piece 2 tops connect cylinder 1, and the bottom is provided with the L shaped edge of a knife 5, and the cylinder 1 and the L shaped edge of a knife 5 place the upper and lower side of cope match-plate pattern 3 respectively.

Lower bolster 6 is provided with square groove 7, and the L shaped edge of a knife 5 stretched in the square groove 7 when cope match-plate pattern 3 fell.

Above content only is to give an example and explanation to what structure of the present invention was done; Under the technical staff in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the design of invention or surmount the defined scope of these claims, all should belong to protection scope of the present invention.
