Description
Technical field
The utility model relates to the technical field of mould, especially a kind of U-shaped bending die.
Background technology
Bending process is the needs according to part shape, by mould and forcing press, blank is curved the Sheet Metal Forming Technology method of certain angle, definite shape workpiece.In actual mechanical process, the situation bending to the parts of U-shaped structure is many, but, in structural design, certain defect is there is in existing great majority for the bending die of bending U-shaped, the baffle plate of the U-shaped parts both sides after bending usually and be not vertical distribution between base plate, between two baffle plates, shape has a certain degree in other words, and cause the situation of substandard products more, qualification rate is lower.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provide a kind of U-shaped bending die of improvement, to ensure the qualification rate of shaping U-shaped parts.
The utility model solves the technical scheme that its technical problem adopts: a kind of U-shaped bending die, the targeting part comprising part of the lower die, part of the upper die and be positioned between the two, described part of the lower die comprises die shoe, is positioned at the die backing plate of die shoe upper surface, is positioned at the concave template of die backing plate upper surface and is positioned at the fixed stripper of concave template upper surface, and described fixed stripper is the rectangular configuration of middle part with middle font hole; Described part of the upper die comprises upper bolster, is positioned at the upper die plate of upper bolster lower surface and is positioned at the punch retainer of upper die plate lower surface, the top of upper bolster arranges die shank, the bottom of described die shank is fixedly connected with the punch that can pass upper bolster, upper die plate, punch retainer, fixed stripper and concave template successively by fastening bolt, the bottom of described die shoe is provided with the stripper bolt that can contact with punch, described stripper bolt is arranged with rectangular coil spring.
Further specifically, be connected with multiple dog screw by multiple alignment pin between described upper bolster, upper die plate and punch retainer.
Further specifically, be connected by multiple dog screw between described die shoe, die backing plate and concave template; Also be connected by multiple dog screw between fixed stripper and concave template.
The beneficial effects of the utility model are: U-shaped bending die of the present utility model, by fixed stripper being processed the rectangular configuration in middle part with middle font hole, punch is not only facilitated to pass through, also be convenient to the styling of U-shaped part in forming process, ensure the baffle plate of U-shaped parts both sides vertical distribution respectively and between base plate, namely the angle formed between two baffle plates is zero degree, and the qualification rate of U-shaped parts finished product significantly improves.

Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, die shoe, 2, die backing plate, 3, concave template, 4, fixed stripper, 5, upper bolster, 6, upper die plate, 7, punch retainer, 8, die shank, 9, punch, 10, stripper bolt, 11, rectangular coil spring, 12, alignment pin, 13, dog screw.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, U-shaped bending die, the targeting part comprising part of the lower die, part of the upper die and be positioned between the two, described part of the lower die comprises die shoe 1, is positioned at the die backing plate 2 of die shoe 1 upper surface, is positioned at the concave template 3 of die backing plate 2 upper surface and is positioned at the fixed stripper 4 of concave template 3 upper surface, and described fixed stripper 4 is the rectangular configuration of middle part with middle font hole; Described part of the upper die comprises upper bolster 5, is positioned at the upper die plate 6 of upper bolster 5 lower surface and is positioned at the punch retainer 7 of upper die plate 6 lower surface, the top of upper bolster 5 arranges die shank 8, the bottom of described die shank 8 is fixedly connected with the punch 9 that can pass upper bolster 5, upper die plate 6, punch retainer 7, fixed stripper 4 and concave template 3 successively by fastening bolt, the bottom of described die shoe 1 is provided with the stripper bolt 10 that can contact with punch 9, and described stripper bolt 10 is arranged with rectangular coil spring 11.
Wherein, be connected with multiple dog screw 13 by multiple alignment pin 12 between described upper bolster 5, upper die plate 6 and punch retainer 7.Be connected by multiple dog screw 13 between described die shoe 1, die backing plate 2 and concave template 3; Also be connected by multiple dog screw 13 between fixed stripper 4 and concave template 3.
By fixed stripper 4 being processed the rectangular configuration in middle part with middle font hole, punch 9 is not only facilitated to pass through, also be convenient to the styling of U-shaped part in forming process, ensure the baffle plate of U-shaped parts both sides vertical distribution respectively and between base plate, the angle namely formed between two baffle plates is zero degree.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
