Abstract
The invention relates to a U-shaped piece bending and correcting die which comprises a female die body, a top plate, locating plates, an upper die base, a wedge and two male die bodies. A male die body groove is formed in the upper die base. The wedge is fixed into the male die body groove through screws. Two kidney-shaped grooves are formed in the male die body groove. The male die bodies are provided with round pins. The round pins are constrained into the kidney-shaped grooves. The male die bodies are restrained into the male die body groove through the round pins. The male die bodies make contact with the inclined faces of the wedge. The two sides of the upper end of the female die body are each fixedly provided with one locating plate. A work groove is formed in the female die body. The top plate is arranged in the work groove. Two guiding rods are arranged at the bottom of the top plate. The guiding rods extend downwards to penetrate through the female die body and extend out of the female die body. The guiding rods are matched with the female die body in a sliding mode. Springs are arranged on the upper surfaces of the male die bodies. The upper ends of the springs are fixedly connected to the upper die base. By the adoption of the structure, the die is simple and reasonable in structure, and capable of punching and correcting a U-shaped work-piece, so that the U-shaped work-piece accurate in appearance is obtained.
Description
Technical field
The present invention relates to a kind of U-shaped part punch die, particularly U-shaped part press-bending straightening die.
Background technology
In the industries such as growing modern industry, automobile, electrical equipment, the part demand amount of various shape is increasing, wherein also comprises U-shaped part, the most complex structure of punch die of existing punching U-shaped, complex operation, and punching U-shaped part effect is out bad, appearance and size is not accurate enough.
Summary of the invention
The U-shaped part press-bending straightening die that can also correct while the object of this invention is to provide a kind of simple and reasonable, easy to operate, punching.
Realize the object of the invention technical scheme as follows:
A kind of U-shaped part press-bending straightening die, comprise die, top board, location-plate, upper bolster, wedge and two pieces of punch, described upper bolster is provided with punch groove, described wedge is screwed in punch groove, described punch groove is provided with two kidney slots, described punch arranges round pin, described round pin constrains in kidney slot, described punch constrains in punch groove by round pin, the contact of incline plane of described punch and wedge, both sides, described die upper end are respectively fixedly installed a location-plate, described die is provided with work groove, a top board is provided with in described work groove, two guide posts are set bottom described top board, described guide post extends downwardly through die and stretches out die, described guide post and die are slidably matched.
Described punch upper surface is provided with spring, and the upper end of described spring is fixedly connected with upper bolster.
After adopting said structure, the present invention is simple and reasonable, and energy punching and correction U-shaped workpiece, obtain profile U-shaped workpiece accurately.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side view of upper bolster in Fig. 1.
In figure: 1 is die, 2 is top board, and 3 is location-plate, and 4 is upper bolster, and 5 is wedge, and 6 is punch, and 7 is punch groove, and 8 is kidney slot, and 9 is round pin, and 10 is work groove, and 11 is guide post, and 12 is spring.
Detailed description of the invention
Die 1 is comprised by the known U-shaped part press-bending straightening die of the present invention of Fig. 1 and Fig. 2, top board 2, location-plate 3, upper bolster 4, wedge 5 and two pieces of punch 6, described upper bolster 4 is provided with punch groove 7, described wedge 5 is screwed in punch groove 7, described punch groove 7 is provided with two kidney slots 8, described punch 6 arranges round pin 9, described round pin 9 constrains in kidney slot 8, described punch 6 constrains in punch groove 7 by round pin 9, the contact of incline plane of described punch 6 and wedge 5, both sides, described die 1 upper end are respectively fixedly installed a location-plate 3, described die 1 is provided with work groove 10, a top board 2 is provided with in described work groove 10, two guide posts 11 are set bottom described top board 2, described guide post 11 extends downwardly through die 1 and stretches out die 1, described guide post 11 is slidably matched with die 1, described punch 6 upper surface is provided with spring 12, the upper end of described spring 12 is fixedly connected with upper bolster 4.
When the present invention works, blank to be placed on top board and to be located by location-plate, and upper bolster presses down, and punch compresses blank, last punch is squeezed by outer by the effect of wedge, make stamping profile be corrected to just size, when taking out stamping, mention upper bolster, promoting guide post makes top board stamping be ejected, punch moves to original position under the action of the spring, and the present invention is simple and reasonable, can punching and correction U-shaped workpiece.
