Abstract

The utility model discloses a round steel product stamping die that bends, including spring, drive block, the centering block of bending, the lower mould of bending, the centering block pivot of bending, pressure flitch, the centering block of bending is connected with pressing the flitch through the centering block pivot of bending, and the drive block sets up in the both sides of pressing the flitch, presses the flitch top to be equipped with the spring, presses the flitch fixed with the round steel location down in the spring force effect when bending the punching press, and the drive block drive is bent the centering block and is rotated along with the centering block pivot of bending, and the bend centering block and the lower mould of bending cooperate the round steel shaping of progressively bending. The utility model discloses a stamping die that bends, the centering block of bending in the product forming process is in along with bending centering block pivot pivoted state always, has guaranteed the mobility of material, alleviate the product damage of a material of bending, and the toper that the lower mould was processed into big -end -up of will bending, can be with the product one shot forming who has the bending of negative angle degree and hypomere.

Description

A kind of round steel product bending press tool

Technical field

The utility model relates to mechanical workout apparatus field, particularly relates to a kind of round steel product bending press tool.

Background technology

The round steel product of similar automotive seat hook, the bending process of product adopts Sheet Metal Forming Technology can well ensure accessory size and production control beat.

The concave-convex mold of common Sheet Metal Forming Technology was simple up and down motion in the past, the direct extruding of concave-convex mold is relied on to make round steel bending and molding, the bending part of round steel certainly will be caused damage like this, affect the strength of materials of round steel bending nook, by improvement, install rotating shaft additional in concave-convex mold nook, it is in rolling condition at forming parts process shaft, this reduces the damage of round steel bending part to a certain extent, but cannot avoid concave-convex mold, in up and down motion process, part is caused damage; And the molding mode of common Sheet Metal Forming Technology, cannot be one time punching molded to the bending product that there is negative angle.

Practical novel content

For the problems referred to above, the utility model object is to provide a kind of round steel product bending press tool, not only makes the damage that bending nook is subject in moulding process of round steel product less, and can make the bending product that there is negative angle can once shaped.

In order to realize above-mentioned purpose, the technical solution of the utility model is as follows:

A kind of round steel product bending press tool, comprise spring, driving block, bending pendulum block, bending counterdie, bending pendulum block rotating shaft, holding pad, described bending pendulum block is put block rotating shaft by bending and is connected with holding pad, block is driven to be arranged at the both sides of holding pad, spring it is provided with above holding pad, during bending punching press, holding pad is by fixing for round steel location under spring elastic force effect, drives block to drive bending pendulum block to put block axis of rotation with bending, and bending pendulum block coordinates round steel progressively bending impact briquetting with bending counterdie.

A kind of preferred version of the present utility model, the right and left of described bending counterdie is provided with block, and the spacing between described block and the distance between described driving block outer wall are suitable.

Another kind of preferred version of the present utility model, the taper that described bending counterdie is big up and small down, the contact surface of described bending pendulum block extruding round steel and the outer conical surface shape adaptation of bending counterdie.

Round steel product bending press tool of the present utility model, in the whole moulding process of round steel product, bending pendulum block is in the state putting block axis of rotation with bending always, well ensure that the mobility of material, maximum degree reduces the injury to round steel bending nook material property, bending counterdie is processed into up big and down small taper, a round steel product bending impact briquetting of band negative angle can be made.

Accompanying drawing explanation

Fig. 1 is the utility model round steel product bending punching die structure schematic diagram;

Fig. 2 is the utility model round steel product bending press tool impact briquetting state graph.

Embodiment

It is easy to make technique means of the present utility model and implementation understand, sets forth the utility model further below in conjunction with specific embodiment.

See Fig. 1, round steel product bending press tool of the present utility model comprises spring 1, drive block 2, bending pendulum block 3, bending counterdie 5, bending pendulum block rotating shaft 7, holding pad 8, bending pendulum block rotating shaft 7 is fixedly installed on holding pad 8, bending pendulum block 3 is put block rotating shaft 7 by bending and is connected with holding pad 8, spring 1 it is provided with above holding pad 8, block 2 is driven to be arranged at the both sides of holding pad 8, before punching press, round steel 6 is placed on punching press counterdie 5, punching press patrix is descending, holding pad 8 is located after touching round steel 6, then punching press patrix continues descending, now spring 1 is compressed, thus compress holding pad 8 and round steel 6 is fixed, drive block 2 to drive bending pendulum block 3 to put block rotating shaft 7 with bending to rotate, bending pendulum block 3 extrudes round steel 6 makes round steel 6 progressively bending, put block 3 by bending to coordinate with bending counterdie 5 and to make round steel 6 shaping. it is provided with block 4 at the two ends, left and right of bending counterdie 5, spacing between two pieces of blocks 4 and drive the distance between block 2 outer wall adaptive, like this in the descending punching course of punching press patrix, block 4 will give to drive block 2 with lateral support, ensure to drive the side force in block 2 punching course.

See Fig. 2, bending counterdie 5 is designed to up big and down small conical by its shape, bending pendulum block 3 is when extruding round steel 6 and the contact surface of round steel 6 and the outer conical surface shape adaptation of bending counterdie 5, such punching press patrix goes downwards to the end, is put by bending and coordinating of block 3 and bending counterdie 5 will make the shape that round steel 6 is bent into band negative angle and hypomere bends.

More than show and describe main feature of the present utility model, mode of operation and advantage of the present utility model. The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification sheets; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.
