Abstract
The utility model discloses a barrel-shaped casing extending mould which comprises a lower base (1), a concave mould system, an upper base (9) and a convex mould system. The concave mould system is composed of a concave mould case (4), a discharge ring (7), a concave mould (16), a location ring (15) and a concave mould fixing plate (8). The convex mould system is composed of a convex mould fixing plate (11), a punch and punch handle (12), a punch clamp (13) and a convex mould (14). The barrel-shaped casing extending mould has the advantages of reducing process of moulds based on a traditional structure, reducing equipment and personnel, being simple to replace and easy to operate, saving labor and materials, being especially suitable for processing metal casings of liquid tantalum electrolytic capacitors and being simple in structure and convenient to use.
Description
Technical field
The utility model relates to the cylindrical case Stretching die, belongs to processing mold manufacturing technology field.
Background technology
The metal shell that liquid tantalum electrolytic capacitor uses is generally silver alloy shell, tantalum metal shell, by silver band or tantalum plate through punching press, extend, the operation such as cut-out processes, generally to just can meet the demands through the enclosure depth of repeatedly extending.And because the sealing requirements of liquid tantalum electrolytic capacitor, employed metal shell can not have monolateral (thick one side is thin on one side), there is cut on the surface or groove, the phenomenon such as crooked.In order to guarantee the crudy of shell, per one manufacturing procedure of at present shell processing, the special-purpose Stretching die of extending guarantees each time.Therefore when the processing shell, die change, equipment debugging are frequent, and configuration personnel and equipment are many; Because die change and equipment debugging are frequent, so that the shell crudy is difficult to guarantee that the shell process-cycle is long that cause product quality to descend, manufacturing schedule does not satisfy the demand in market.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid tantalum electrolytic capacitor that can be applicable to add equipment needed thereby in man-hour, the less general cylindrical case Stretching die of personnel with metal shell.
The purpose of this utility model is achieved through the following technical solutions: the cylindrical case Stretching die, and it comprises bottom base, die system, top base and punch system, wherein,
Described die system is comprised of die case, discharging ring, die, centring ring and die block, die case is fixed on the bottom base by pin and screw, and centring ring, die and discharging ring closely are fixed on the die case from top to bottom by die block;
The punch system is comprised of punch retainer, drift and punch-holder shank, drift folder and punch, and punch is clipped in the drift folder and places together drift and punch-holder shank, and drift and punch-holder shank embed in the top base and by punch retainer and fix.
Be provided with the guide pillar with guide pin bushing between described bottom base and top base.
Be provided with backing plate between described die case and the bottom base.
Be provided with latch between described punch retainer and the top base.
The beneficial effect of the utility model method is: reduced the processing of overpaying mould on the basis of traditional structure, equipment and personnel have been reduced, die change is simple, easy to operate, manpower and materials have been saved, be specially adapted to be applicable to liquid tantalum electrolytic capacitor and process with metal shell, and have characteristics simple in structure, easy to use.

The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
Such as Fig. 1, the cylindrical case Stretching die, it comprises bottom base 1, die system, top base 9 and punch system, wherein,
Described die system is comprised of die case 4, discharging ring 7, die 16, centring ring 15 and die block 8, die case 4 is fixed on the bottom base 1 by pin 2 and screw 17, and centring ring 15, die 16 and discharging ring 7 closely are fixed on the die case 4 from top to bottom by die block 8;
The punch system is comprised of punch retainer 11, drift and punch-holder shank 12, drift folder 13 and punch 14, punch 14 is clipped in the drift folder 13 and places together drift and punch-holder shank 12, fix in drift and the punch-holder shank 12 embedding top bases 9 and by punch retainer 11, punch retainer 11 can be fixed punch 14, drift folder 13 simultaneously together.
9 of described bottom base 1 and top bases are provided with the guide pillar 5 with guide pin bushing 6.
Be provided with backing plate 3 between described die case 4 and the bottom base 1.
Be provided with latch 10 between described punch retainer 11 and the top base 9.
