Abstract
The utility model provides a curved workpiece-machining die, which comprises a die holder, a female die and a male die, the male die comprises a curving male die and a cutting male die, and is located over the female die, the female die is mounted on the die holder, ejector pins are arranged in the female die, the tops of the ejector pins are connected with a discharge block, a striking pin and a discharge pin are arranged sequentially from the top down in the curving male die, and the cutting male die is arranged under the discharge pin. On the basis of the ordinary curving male die, the curved workpiece-machining die is added with the cutting male die, consequently, when the curved workpiece-machining die operates, the female die and the curving male die can curve a workpiece into the shape of a complete U, the cutting male die then cuts off the middle part of the U-shaped workpiece, so that two half U-shaped workpieces are produced at the same time, and therefore the curved workpiece-machining die not only increases working efficiency, but also dispenses with the process of correction, decreases labor intensity, and saves the production cost.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of workpiece processing mold of arc-shaped workpiece processing mold, particularly half U type.
Background technology
In production process, usually need to process some asymmetric curved workpieces, conventionally make workpiece carry out proofreading and correct again after bending.The intensity of workpiece is large, and correction work can be more difficult, and production efficiency ground, production cost uprise, and make labour intensity high simultaneously, and asymmetric workpiece has relatively high expectations to mould conventionally, simultaneously larger to the damage ratio of mould.Such as the workpiece of half U type, due to the particularity of its shape, common mould conventionally cannot production and processing.
Utility model content
utility model object: the purpose of this utility model is just to provide a kind of arc-shaped workpiece processing mold.
technical scheme:for achieving the above object, the utility model has been taked following technical scheme:
A kind of arc-shaped workpiece processing mold, comprise die holder, die and punch, it is characterized in that: described punch comprises crooked punch and cuts off punch, described punch be positioned at described die directly over, described die is installed on described die holder, described die inside is provided with ejector beam, described ejector beam top connects unloading block, in described crooked punch, be provided with successively from top to bottom knockout rod and discharge arm, described cut-out punch is located at described discharge arm below, described ejector beam and unloading block respectively have two covers, are located at respectively the described cut-out punch left and right sides.Compared to common mould, be only provided with a punch and die; of the present utility modelly on common crooked punch basis, set up a cut-out punch; the utility model at work like this; by die and crooked punch workpiece can be bent to one complete U-shaped; by cutting off punch, cut again the mid portion of U-shaped workpiece; so just can complete the workpiece of two half U types simultaneously; not only improve operating efficiency and also saved the program of proofreading and correct; reduce labour intensity, saved production cost.In designs such as the unloading block of cutting off punch left and right sides same design and ejector beams, guaranteed that the half U type part of producing is identical, made Workpiece standard type better.
Described crooked punch top is provided with die shank, and described die shank is positioned at the described knockout rod left and right sides.
Described die holder two ends are provided with screw, and described screw is fixedly connected with described die holder and die.
Described ejector beam is connected with elastic buffer.
beneficial effect:adopt the following advantage that the utlity model has of technique scheme:
Arc-shaped workpiece processing mold of the present utility model is reasonable in design, easy to use, production efficiency is high, of the present utility modelly on common crooked punch basis, set up a cut-out punch, the utility model at work like this, by die and crooked punch workpiece can be bent to one complete U-shaped, by cutting off punch, cut again the mid portion of U-shaped workpiece, so just can complete the workpiece of two half U types simultaneously, not only improve operating efficiency and also saved the program of proofreading and correct, reduce labour intensity, saved production cost; The utility model becomes symmetric workpiece processing by the processing of asymmetric workpiece, thereby the requirement of strength of mould is reduced, and has reduced the working strength of mould, makes die life elongated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-elastic buffer, 2-die holder, 3-screw, 4-die, 5-ejector beam, 6-unloading block, the crooked punch of 7-, 8-die shank, 9-knockout rod, 10-discharge arm, 11-workpiece, 12-cut off punch.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further set forth.
As shown in the figure: a kind of arc-shaped workpiece processing mold of the present utility model, comprise die holder 2, die 4 and punch, it is characterized in that: described punch comprises crooked punch 7 and cuts off punch 12, described punch be positioned at described die 4 directly over, described die 4 is installed on described die holder 2, described die 4 inside are provided with ejector beam 5, described ejector beam 5 tops connect unloading block 6, in described crooked punch 7, be provided with successively from top to bottom knockout rod 9 and discharge arm 10, described cut-out punch 12 is located at described discharge arm 10 belows, described ejector beam 5 and unloading block 6 respectively have two covers, be located at respectively described cut-out punch 12 left and right sides, described ejector beam 5 is connected with elastic buffer 1.
The course of work of the present utility model and principle are as follows:
The utility model and forcing press support the use, arc-shaped workpiece processing mold is positioned on forcing press, ejector beam 5 under the effect of elastic buffer 1 by unloading block 6 jack-up, make it concordant with die 4, pending workpiece 11 is positioned in die 4, forcing press moves down, crooked punch 7 moves down, then at crooked punch 7, under the acting in conjunction of die 4 and unloading block 6 by workpiece 11 bendings, then forcing press continues to move down, the middle part that cuts off 12 pairs of workpiece 11 bottoms of punch cuts off, meanwhile, 7 pairs of workpiece 11 of crooked punch are proofreaied and correct shaping, under the acting in conjunction of cutting off punch 12 and crooked punch 7, generate like this workpiece 11 of two half U types, then on forcing press, move, cut off punch 12 separated with workpiece 11 with crooked punch 7, the workpiece 11 of moulding ejects in die 4 under the effect of unloading block 6, then removed, the waste material producing in production process removes from crooked punch 7 by knockout rod 9 and discharge arm 10, so just completed the processing of half U type workpiece.The utility model can two half U type workpiece of disposable production, have also avoided further correcting process simultaneously, have greatly improved production efficiency, have reduced labour intensity, have saved production cost.
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.
