Abstract
The utility model provides a spring bending die. The spring bending die comprises a die holder, a female die and a male die and is characterized in that the female die is arranged on the die holder, the male die is located above the female die, the lower part of the female die is provided with a spring of which the top is connected to a lower die, the top of the female die is provided with a positioning plate which can move left and right, the positioning plate is located at two sides of the lower die, and the descending limit position of the male die is higher than the lowest point of a corner of the lower die. The spring bending die is simple and reasonable in structure, practical and stable and can be used for completing the processing on an asymmetric workpiece for one time, and the production efficiency is improved; meanwhile, the descending limit position of the male die is set to be higher than the lowest point of the corner of the lower die, and the male die is protected, so the service life of the die is prolonged; the lower die can be exchanged to realize the processing on workpieces in different shapes, and the application range is wider.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of spring bending mould.
Background technology
In production process, usually need to process the workpiece of some shape matching complexity, spring workpiece such as a kind of Z-type, if the workpiece bending machining for Z-type need to be passed through two procedures conventionally with general mould, if like this, contrast locating is more difficult, and production efficiency is also lower.And, for the workpiece of this asymmetry of picture Z-type, very large to the punch damage of mould in the course of the work, thus cause reduce the service life of mould.
Utility model content
utility model object: the purpose of this utility model is just to provide a kind of spring bending mould.
technical scheme:for achieving the above object, the utility model has been taked following technical scheme:
A kind of spring bending mould, comprise die holder, die and punch, it is characterized in that: described die is installed on described die holder, described punch is located at the top of described die, described die bottom is provided with spring, described spring top is connected with counterdie, described die top is provided with the location-plate that can move left and right, described location-plate is positioned at the both sides of described counterdie, the extreme position that described punch declines is higher than the minimum point at described counterdie turning, exceed 0.1-0.3mm, described spring inner is provided with ejector pin, between described spring and described counterdie, be provided with stop screw, described location-plate top is once provided with pad and dog screw from bottom to up.The utility model is compared to common mould, on die, have additional counterdie, by die, counterdie and punch three, jointly the workpiece of asymmetry is processed, can disposablely complete processing work, compared to two procedures in the past, improved greatly production efficiency; The extreme position that the utility model design punch declines, higher than the minimum point at described counterdie turning, has so just been protected punch, thereby has been extended the service life of punch, and then extended the service life of mould.
Described counterdie is Z-type.
Between described die and die holder, be provided with screw, described screw is fixed on described die on described die holder.
Described screw has 2, is located at respectively the left and right sides of described die.
Described counterdie is replaceable, and its shape can change.The shape of counterdie can be according to wanting the shape of crooked workpiece to adjust.
beneficial effect:adopt the following advantage that the utlity model has of technique scheme:
The utility model is simple and reasonable for structure, practical, stable, can disposablely complete the processing to asymmetry workpiece, has improved production efficiency; Set the extreme position of punch decline higher than the minimum point at described counterdie turning simultaneously, protected punch, thereby extended the service life of mould; The utility model can be changed counterdie, realizes difform workpiece is processed, and the scope of application is wider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-die holder, 2-screw, 3-die, 4-location-plate, 5-counterdie, 6-punch, 7-dog screw, 8-pad, 9-stop screw, 10-ejector pin, 11-spring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further set forth.
As shown in the figure: a kind of spring bending mould of the present utility model, comprise die holder 1, die 3 and punch 6, it is characterized in that: described die 3 is installed on described die holder 1, described punch 6 is located at the top of described die 3, described die 3 bottoms are provided with spring 11, described spring top is connected with counterdie 5, described die top is provided with the location-plate 4 that can move left and right, described location-plate 4 is positioned at the both sides of described counterdie 5, the extreme position that described punch 6 declines is higher than the minimum point at described counterdie 5 turnings, exceed 0.1-0.3mm, described counterdie 5 is Z-type, described spring 11 inside are provided with ejector pin 10, between described spring 11 and described counterdie 5, be provided with stop screw 9, described location-plate 4 tops are once provided with pad 8 and dog screw 7 from bottom to up, between described die 3 and die holder 1, be provided with screw 2, described screw 2 is fixed on described die 3 on described die holder 1.
The course of work of the present utility model and principle are as follows:
The utility model and forcing press support the use, workpiece to be processed is put into mould, forcing press moves down, punch 6 also moves down and contacts with workpiece gradually, then punch 6, die 3, counterdie 5 is jointly to workpiece effect, workpiece is bent, for preventing workpiece movable, can adjust by 4 pairs of location of workpieces of location-plate, when punch 6 arrives its limit dead point, punch 6 and die 3, 5 pairs of workpiece of counterdie are adjusted and are proofreaied and correct moulding, then on forcing press, move, punch 6 is separated with workpiece, 11 pairs of counterdies 5 of spring act on, workpiece is ejected to the die cavity of die 3, can take the workpiece of moulding away, whole workpiece brake forming process finishes.By the utility model can brake forming by asymmetrical workpiece such as being the workpiece of Z-type, improved greatly production efficiency.
Below be only a kind of specific embodiment of the present utility model; should understand these embodiments and only for the utility model is described, be not used in restriction scope of the present utility model; after having read the utility model; those skilled in the art all fall within the utility model claims to the modification of the various equivalent form of values of the present utility model and limit, and protection domain of the present utility model should be as the criterion with claim of the present utility model.
