Abstract

The utility model discloses a stamping die which comprises a convex die, a concave die and a stamping channel arranged between the convex die and the concave die, wherein a plurality of floating blocks and movement blocks are arranged in the stamping channel; groups of parallel and different-height flat guide rails are arranged in the stamping channel; the bottom surfaces of the floating blocks and the movement blocks are fitted with the flat guide rails in shape; and the floating blocks and the movement blocks can slide along the flat guide rails to change the width of a stamped workpiece. The top ends of the floating blocks and the movement blocks are connected with telescopic control levers, and the control levers are fixedly connected to the concave die. The floating blocks and the movement blocks can be adjusted to be embedded into the different-height flat guide rails through the telescopic control levers so as to change the depth of the stamping channel in which the floating blocks and the movement blocks are arranged and to further change the length of the stamped workpiece. The stamping die has the benefits that the length and width of the workpiece to be stamped can be changed at the same time, and different-shaped products can be stamped by adjusting the quantity and changing different shapes of the movement blocks.

Description

A kind of diel

Technical field

The utility model relates to mould, relates in particular to a kind of diel.

Background technology

Punching press is at room temperature, utilizes the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Punching press can be made the workpiece that has reinforcement, rib, fluctuating or flange that other method is difficult to make, and the vehicle body of automobile, chassis, fuel tank, radiator fin etc. all are that punch process forms.

But a present secondary diel can only stamp out a kind of product of length dimension, wants to stamp out the product of different length, just need make new mould again.If will make four kinds of size differences but the similar product of shape, then need to make the fourth officer mould, it is higher not only to spend cost, and more the mold exchange program is loaded down with trivial details and lose time.

Also there is mould to reach the purpose of punching press different size, but is only can change the length or the width of stamping products separately mostly, and can not both take into account by architecture advances.

The utility model content

In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of diel, can change the length and the width of stamping products simultaneously, and the product of several different sizes of adjustable size energy punching press, helps reducing production costs.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of diel comprises punch, die, and the punching press passage between described punch and die is provided with a plurality of buoyant pieces and movable block in the described punching press passage, and the flat guide that many groups are parallel, height differs is set in the described punching press passage.

Further, described buoyant piece and movable block are positioned on the above-mentioned flat guide, and the bottom shape and the flat guide of buoyant piece and movable block match, and make it can be along described flat guide move left and right, thereby change the width of wanting stamped workpieces.

Described buoyant piece also is connected with control lever is detachable with the top of movable block, is convenient to change difform movable block.

Described control lever is telescopic, and preferably, its inside is provided with spring, can conveniently elongate or shorten according to demand; Described extension type control lever is connected on the described die.

Preferably, described buoyant piece is equal with the movable block position, helps described buoyant piece the material around the movable block is all floated, and allows strip keep same plane all the time above movable block, prevents that product from breaking, and die breaks, the accuracy when having guaranteed punch die.

Can regulate buoyant piece and movable block by described telescopic control lever and embed in the different flat guide of height, changing the buoyant piece and the degree of depth of movable block in described punching press passage, during punch die so change want the length of stamped workpieces;

By such scheme, can conveniently change length and the width of wanting stamped workpieces, therefore need stamp out the same mould product of different size, just do not needed frequently more mold exchange; Come the workpiece of the different requirements of punching press and make difform product with the difform movable block of replacing by the quantity of regulating described movable block.

The beneficial effects of the utility model are, the mould structure design is ingenious, and the size that changes stamped workpieces easily and effectively, and is easy and simple to handle, reduced labor content, saved resource, the also corresponding cost of making mould that reduced.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a plurality of parallel flat guide front view among Fig. 1.

The specific embodiment:

Be easy to understand understanding in order to make creation characteristic of the present utility model, technological means and to reach purpose, further set forth the utility model below in conjunction with specific embodiment.

Embodiment:

Referring to Fig. 1 and Fig. 2, a kind of diel comprises the punch 1 that is positioned at the top, the die 2 and the middle punching press passage 3 of below, and three groups of parallel, that height is different flat guides 31 are set in the described punching press passage 3.

Equal buoyant piece in a plurality of positions 5 and movable block 6 are set in the punching press passage 3, described buoyant piece 5 matches with flat guide 31 with the bottom shape of movable block 6 and is convenient to be connected, buoyant piece 5 can embed on it with movable block 6 and can horizontally slip along described flat guide 31, thereby can change the width of wanting stamped workpieces, operation is very easy, accurately reliable.

The top of buoyant piece 5 and movable block 6 also with telescopic 4 detachable connections of control lever, change the movable block 6 of respective shapes when being convenient on the punching press different workpieces.

In the telescopic control lever 4 spring 41 is set, changes the length that the body of rod that links to each other stretches out, and then promote buoyant piece 5 and stretch into highly different flat guide 31, and then the length of stamped workpieces is wanted in change with movable block 6 by compression spring 41.

This structure design of signing an undertaking is ingenious, and the size of change stamped workpieces easily and effectively, and is easy and simple to handle, reduced labor content, saved resource, the also corresponding cost of making mould that reduced.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
