Abstract
The invention relates to a necking die of a lampshade. The necking die comprises an upper die base (1), a lower die base (2), guide columns (3) and a die shank (8). The guide columns (3) are vertically fixed to the four corners of the lower die base (2), the upper die base (1) vertically slides along the guide columns (3), and the die shank (8) is fixedly installed on the upper die base (1). The necking die further comprises a movable female die (5), a fixed female die (6) and a male die (7). The lower die base (2) is fixedly provided with a male die fixing plate (4) through a dowel, and the male die (7) is fixedly installed on the male die fixing plate (4). The movable female die (5) is arranged above the male die fixing plate (4) and matched with the male die (7). The fixed female die (6) is fixedly installed below the upper die base (1) through a screw (13) and a dowel. A necking structure is arranged in the fixed female die (6), and the fixed female die (6) is matched with the movable female die (5). The necking die has the advantages that matching is accurate, the work efficiency is high and die release is convenient.
Description
Technical field
The present invention relates to technical field of mold, particularly lampshade reducing die.
Background technology
Reducing is by preshaped good cylindrical element or pipe fitting blank, a kind of forming process of its oral area being dwindled by necking die.The application of reducing operation is more extensive, can be used for the reducing processing of cartridge case, gun shell, steel gas bottle, vertical pipe of bicycle frame, saddle saddle pipe, steel pipe drawing etc.General operation, for to exert pressure to cylindrical element or pipe fitting blank, makes it to slide to the die of reducing die, cylinder material necking end reduced under the pressure-acting of die inwall.The structure of reducing die is divided into without supporting, external support and three kinds of forms of interior external support according to supporting situation, can choose corresponding supporting structure according to the dimension precision requirement of reducing deformation and reducing part.Relatively simple without supporting structure, but in reducing process, coordinate inaccurately, blank deformation is unstable, causes product quality to decline.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of and coordinate precision, operating efficiency is high and the lampshade reducing die that is convenient in demoulding.
Object of the present invention is achieved through the following technical solutions: lampshade reducing die, it comprises upper bolster, die shoe, guide pillar and die shank, guide pillar is vertically fixed on four jiaos of die shoe, upper bolster slides up and down along guide pillar, die shank is fixedly mounted on the top of upper bolster, it also comprises movable matrix, fixedly die and punch, on described die shoe, by pin, be installed with punch retainer, punch is fixedly mounted on punch retainer, movable matrix is arranged at the top of punch retainer, and coordinates with punch; Fixedly die is fixedly mounted on the below of upper bolster by screw and pin, and fixedly die inside is provided with throat structure, and fixedly die coordinates with movable matrix.
Described upper bolster and be fixedly also provided with die backing plate between die.
Between described upper bolster and die shank, be also provided with stop pin.
Inner cooperation of described fixedly die is provided with push piece plate, and die shank inside is provided with vertical push rod, and push rod is pressed on the upper surface of push piece plate.
On described die shoe, be also provided with push rod, the upper end of push rod is passed die block and is withstood on movable matrix.
Between described upper bolster and guide pillar, be also provided with guide pin bushing, guide pin bushing is fixedly mounted on upper bolster, and guide pin bushing and guide pillar are slidably matched.
The present invention has the following advantages:
1, by guide pillar, coordinate with upper bolster, upper bolster moves up and down along guide pillar, and guide pillar linearity is good, and die coordinates with punch accurately, product reducing dimensionally stable, and reducing quality significantly promotes.
2, fixedly after die, punch and movable matrix matched moulds, blank completes reducing, and one-step shaping is simple to operate, and production efficiency is high.
3, by push rod and push piece plate, coordinate, after moulding, push rod promotes push piece plate downwards, and push piece plate ejects fixedly die by reducing workpiece, is convenient in demoulding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-upper bolster, 2-die shoe, 3-guide pillar, 4-punch retainer, 5-movable matrix, 6-is die fixedly, 7-punch, 8-die shank, 9-push rod, 10-push rod, 11-guide pin bushing, 12-die backing plate, 13-screw, 14-stop pin, 15-push piece plate.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, lampshade reducing die, it comprises upper bolster 1, die shoe 2, guide pillar 3 and die shank 8, guide pillar 3 is vertically fixed on four jiaos of die shoe 2, upper bolster 1 slides up and down along guide pillar 3, die shank 8 is fixedly mounted on the top of upper bolster 1, it also comprises movable matrix 5, fixedly die 6 and punch 7, on described die shoe 2, by pin, be installed with punch retainer 4, punch 7 is fixedly mounted on punch retainer 4, movable matrix 5 is arranged at the top of punch retainer 4, and coordinates with punch 7; Fixedly die 6 is fixedly mounted on the below of upper bolster 1 by screw 13 and pin, and fixedly die 6 inside are provided with throat structure, and fixedly die 6 coordinates with movable matrix 5.
Described upper bolster 1 and be fixedly also provided with die backing plate 12 between die 6.
Between described upper bolster 1 and die shank 8, be also provided with stop pin 14.
Described inner cooperation of fixedly die 6 is provided with push piece plate 15, and die shank 8 inside are provided with vertical push rod 9, and push rod 9 is pressed on the upper surface of push piece plate 15.
On described die shoe 2, be also provided with push rod 10, the upper end of push rod 10 is passed die block 4 and is withstood on movable matrix 5.
