Abstract

The utility model discloses a novel negative angle bending device, which comprises a first bending forming punch, a second bending forming punch, a swinging forming block, a pin roll and a bending forming die. The swinging forming block is connected moveably with the second bending forming punch through the pin roll in a movable mode, and the first bending forming punch, the second bending forming punch and the bending forming die are respectively arranged on an upper mould and a lower mould of a mould. The device has the advantages of being simple in operation, low in technical requirement and processing cost, and capable of reducing the damage to personnel and equipment greatly.

Description

A kind of novel negative angle apparatus for bending
Technical field
The utility model relates to the Machining Technology field, is specifically related to a kind of apparatus for bending.
Background technology
Bending and molding is a kind of common technology in the punching production, is that independent Bending punch and bending and molding piece comes moulding usually.Though such structure is simple, for the special bending structure of product requirement, especially have being difficult for taking off and expecting and bending of negative angle, often do not reach requirement of client.At present; For the similar structure employing of bending in the common progressive die all is the side slide mechanism that the vertical up-or-down movement of punch press is converted to horizontal movement; And then after bending and molding is accomplished; Against the disengaging of accomplishing product of returning of side slide mechanism, this structure is high for the requirement on machining accuracy height and the processing cost of mould, and this kind structure mold maintenance difficult.Moreover, in lasting a large amount of production of the progressive die, in case product produces misdelivery in mould, cause blocking of side slide mechanism easily, and then the slotting tool mechanism of patrix is left behind, if mould continues motion, will cause serious injury to mould and producers.
The utility model content
In order to solve the problem of above-mentioned existence, the purpose of the utility model is to provide a kind of novel flexibly negative angle apparatus for bending simple to operate, easy to use.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel negative angle apparatus for bending; It is characterized in that; Comprise the first bending and molding drift, the second bending and molding drift, swing-shaping piece and bending and molding die; Said swing-shaping piece flexibly connects through a bearing pin and the second bending and molding drift, is acute angle between the outer side edges of said swing-shaping piece and the base.
Preferably, the workpiece contact-making surface and the horizontal plane of the said first bending and molding drift acutangulate.
Preferably, the said second bending and molding drift is provided with limited mouth.
Preferably, the side bottom the said swing-shaping piece is a fillet.
The angle of the utility model swing-shaping piece outer side edges and acute angle that the base is is exactly that workpiece is wanted angle bending; The swing-shaping piece is movably connected through a bearing pin and the second bending and molding drift, and therefore can be better, safer when touching workpiece rotate around bearing pin matches with the first bending and molding drift; Completion is to the negative angle bending of product; After the negative angle bending was accomplished, the swing-shaping piece was driven by second Bending punch and moves upward, and the swing-shaping piece resets owing to gravity; The quality of product has been guaranteed in the collision of swing-shaping piece and product when having avoided rising.This novel negative angle apparatus for bending is than existing apparatus, and its production operation is simple, and product quality is better, has improved production efficiency greatly, has guaranteed the qualification rate of product, has reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model when not closed;
Structural representation when Fig. 2 is the utility model closure;
Fig. 3 is the structural representation after the utility model separates.
Among the figure 1, swing-shaping piece 2, the first bending and molding drift 3, the second bending and molding drift 4, bearing pin 5, workpiece 6, bending and molding die
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is made further description explanation.
To a kind of novel negative angle apparatus for bending shown in Figure 3, comprise swing-shaping piece 1, the first bending and molding drift 2, the second bending and molding drift 3, bearing pin 4, workpiece 5 and bending and molding die 6 like Fig. 1, said workpiece 5 abuts against on the said bending and molding die 6; Because of needs carry out the negative angle bending to workpiece, workpiece processing for ease is so be movably connected said swing-shaping piece 1 through a bearing pin 4 and the second bending and molding drift 3; And swing-shaping piece 1 bottom one side is made as fillet, when swing-shaping piece 1 touched the workpiece 5 that abuts against on the bending and molding die 6 in the device closed process, 1 of swing-shaping piece slided along the fillet direction; Match with the first bending and molding drift 2, to reach the negative angle bending of workpiece, when device separates; The said second bending and molding drift 3 drives swing-shaping pieces 1 and moves upward, and swing-shaping piece 1 has avoided that swing-shaping piece 1 collides workpiece 5 when separating because gravity restores to the original state; Shape and precision to workpiece 5 impact, thereby have improved the qualification rate of product greatly, have simplified the process of product; Improved production efficiency greatly; Reduced production cost, when device closed, the limited mouth on the said second bending and molding drift 3 and the top margin of swing-shaping piece 1 join; Jointly swing-shaping piece 1 there is downward active force left with the first bending and molding drift 2; After workpiece 5 negative angle bendings were accomplished, the continuation of the limited mouth restriction swing-shaping piece 1 on the second bending and molding drift 3 was slided, and prevents because of impulse force is excessive the second bending and molding drift 3 to be caused excessive compression; So that cause the damage of equipment; Therefore novel negative angle apparatus for bending is improving production efficiency greatly, can also reduce the damage of equipment when having reduced production cost, has prolonged the service life of equipment greatly.
Above-described only is the optimal way of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these also should be regarded as within the protection domain of the utility model.
