Abstract
The invention relates to a punching die used for passenger car silencer tube body bulging. The punching die comprises a bottom plate, stand columns, a top plate, a concave die and a convex die. The stand columns are arranged on the bottom plate, the top plate is arranged at the upper ends of the stand columns, the concave die is formed on the top plate and corresponds to the convex die, the convex die is fixed on the bottom surface of a convex die installation plate, and the concave die comprises a fixed part and a movable part, wherein the fixed part is fixed to the top plate, and the fixed part and the movable part are hinged through a hinge and locked through a locking device. The concave die of the die for tube body bulging is designed to be of a split structure, namely, the concave die is designed into two halves, then the two halves are hinged through the hinge and locked through the locking device, so that the concave die is opened from the side face, a workpiece is convenient to take and place, production efficiency is greatly improved, labor intensity of a worker is relieved, and the core competitiveness of an enterprise is improved.
Description
technical field:
The present invention relates to passenger vehicle silencer technical field, be specifically related to the diel of a kind of passenger vehicle silencer cylinder bulging.
background technology:
In muffler desing, consider the factors such as easy for installation and technique cooperation, generally silencer cylinder end is designed to bulging or turnup structure, this cylindrical shell end bulging or turnup structure are quite general in the field of passenger vehicle noise elimination at present, and current be generally to realize by the punching press of cylindrical shell bulging die when manufacturing this cylindrical shell bulging structure.Traditional cylindrical shell bulging die is to form by textural associations such as punch, die and auxiliary equipment punch installing plate thereof, die installing plate, column, backing plate, base plates, core work parts punch, die all adopt overall structure, facts have proved that this frame mode die life is high, punching press plate quality is good, but there is a very large drawback in this kind of structure, inefficiency, particularly pick and place workpiece very inconvenient, this does not obviously conform to present advocated high efficiency production.If can design and produce a kind of structure, can either retain the advantage of traditional structure, can greatly enhance productivity again, for cylindrical shell bulging die structural design, be or a difficult problem so.
summary of the invention:
In sum, in order to overcome the deficiency of prior art problem, the invention provides the diel of a kind of passenger vehicle silencer cylinder bulging, it is that the Die Design of cylindrical shell expanding die is become to split-type structural, be about to Die Design into two, then hinged by jointed shaft, by locking mechanism, lock, thereby die can be opened from the side, thereby conveniently pick and place workpiece, thereby greatly enhance productivity, reduce labor strength, improve the core competitiveness of enterprise.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The diel of a kind of passenger vehicle silencer cylinder bulging, wherein: comprise base plate, column, top board, die and punch, on base plate, be provided with column, column upper end is provided with top board, on described top board, is provided with die, die is corresponding with punch, punch is fixed on the bottom surface of punch installing plate, and described die comprises standing part and movable part, and standing part is fixed on top board, standing part and movable part are hinged by hinge, by locking device, lock.
Technical scheme of the present invention can also be achieved in that described locking device comprises rotating dog, U-shaped fixture block, locking nut and mount pin, one end of rotating dog is connected with the standing part of die by mount pin, by standing part and the movable part of locking nut and U-shaped fixture block locking die.
Technical scheme of the present invention can also be achieved in that on described base plate and be provided with backing plate, the die on the corresponding top board of backing plate.
Technical scheme of the present invention can also be achieved in that the top of the standing part on described die is provided with alignment pin and locating hole.
Technical scheme of the present invention can also be achieved in that on described base plate and be provided with mounting groove.
Technical scheme of the present invention can also be achieved in that on described top board and be provided with U-shaped groove, by U-shaped groove, pick and place workpiece.
Beneficial effect of the present invention is:
1, the present invention becomes split-type structural by the Die Design of cylindrical shell expanding die, be about to Die Design into two, then hinged by jointed shaft, by locking mechanism, lock, thereby die can be opened from the side, thereby conveniently pick and place workpiece, thereby greatly enhance productivity, reduce labor strength, improve the core competitiveness of enterprise.
2, the present invention is simple in structure, easy to operate, result of use is good, can realize the convenient and swift of blowing, feeding, can effectively improve the ram efficiency of silencer cylinder bulging structure, thereby improves enterprises production efficiency.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of the mold closing state of die of the present invention;
Fig. 3 is the structural representation of the die opening state of die of the present invention.
the specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3, the diel of a kind of passenger vehicle silencer cylinder bulging, comprise base plate 1, column 2, top board 3, die 4 and punch 5, on base plate 1, be provided with column 2 and mounting groove 18, on base plate 1, be provided with backing plate 15, die 4 on the corresponding top board 3 of backing plate 15, column 2 upper ends are provided with top board 3, on described top board 3, be provided with die 4, die 4 is corresponding with punch 5, punch 5 is fixed on the bottom surface of punch installing plate 6, described die 4 comprises standing part 7 and movable part 8, standing part 7 is fixed on top board 3, standing part 7 is hinged by hinge 9 with movable part 8, by locking device 10, lock, locking device 10 comprises rotating dog 11, U-shaped fixture block 12, locking nut 13 and mount pin 14, one end of rotating dog 11 is connected with the standing part 7 of die 4 by mount pin 14, by the standing part 7 and movable part 8 of locking nut 13 and U-shaped fixture block 12 locking dies 4.The top of the standing part 7 on described die 4 is provided with alignment pin 16 and locating hole 17.On described top board 3, be provided with U-shaped groove 19, by U-shaped groove 19, pick and place workpiece
