Abstract

The utility model relates to a sheet stamping device used for processing a sheet. A stamping hydraulic machine comprises a working table, a lower terrace die and an upper concave die, wherein the lower terrace die is fixedly arranged on the upper end face of the working table, and the upper concave die is arranged above the lower terrace die and matched with the lower terrace die. The upper concave die is fixedly arranged on a movable block which can move vertically in a reciprocating mode. A lifting plate is arranged below the working table. The upper end face of the lifting plate is fixedly provided with at least two guide top rods. The upper ends of the guide top rods penetrate through the working table and the lower terrace die, and are exposed above the lower terrace die. A workpiece placing panel is fixedly arranged on the guide top rods which are exposed out of the lower terrace die. A receding hole is formed in the middle portion of the workpiece placing panel, and a terrace die on the lower terrace die can penetrate through the receding hole. A driving cylinder is arranged below the working table so as to drive the lifting plate to move vertically in the reciprocating mode. The upper end of a telescopic rod of the driving cylinder is fixed with the lower end face of the lifting plate. The sheet stamping device has the advantages of being simple in structure, convenient to operate, easy to install and dismantle, accurate in locating, high in stamping quality and small in occupied area.

Description

Sheet stamping device
Technical field
The utility model relates to the pressing equipment in the machining equipment technical field, is specifically related to a kind of sheet stamping device that thin plate is processed.
Background technology
Present sheet stamping device complex structure, complex operation, accurate not to the punching press of thin plate, when installation, dismounting mould, inconvenience, changing a mold will for a long time, affect operating efficiency.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of sheet stamping device, and it is simple in structure, easy to operate, easy installing/dismounting, accurate positioning, stamping quality height.
The realization the technical solution of the utility model is as follows:
Sheet stamping device, this hydralic stamping press comprises workbench, be fixedly installed on the lower punch of workbench upper surface, and be positioned at the upper cavity die that lower punch top cooperates with lower punch, this upper cavity die is fixedly installed on the movable block that can pump, described workbench below is provided with lifter plate, the upper surface of this lifter plate is fixedly installed two guiding push rods at least, workbench is passed in the upper end of guiding push rod, lower punch is exposed at the top of lower punch, expose and be fixedly installed workpiece on the guiding push rod of lower punch and place dull and stereotyped, this workpiece is placed dull and stereotyped middle part and is offered the resigning hole that passes for the punch on the lower punch, and being arranged on the driving cylinder that driving lifter plate in workbench below pumps, the expansion link upper end of this driving cylinder is fixedly installed with the lower surface of lifter plate.
Be provided with guide pipe in the through hole that described workbench, lower punch pass for the guiding push rod, can carry out precise positioning to the guiding push rod like this, the push rod that reduces to lead and through hole between error, the guide pipe inner wall smooth, it is little rub, reduces the wearing and tearing to the push rod that leads.
In order further to reduce error and to reduce wearing and tearing to the guiding push rod, the guide pipe of setting is same in the through hole that the guide pipe that arranges in the through hole that described workbench passes for the guiding push rod and lower punch pass for the guiding push rod.
Described upper cavity die adopts the connected mode of bolt or screw to be fixedly connected on the movable block lower surface.
The upper end of described guiding push rod is placed the dull and stereotyped thread connecting mode that adopts with workpiece and is connected.
Adopted such scheme, before to sheet stamping, under the effect of driving cylinder, workpiece is placed flat board and is upwards ejected by the guiding push rod, be placed on workpiece with thin plate and place on the flat board this moment, and under the effect of movable block, upper cavity die moves to the lower punch direction, when upper cavity die carries out punching press to thin plate, driving cylinder can not produce larger resistance, does not affect upper cavity die, the matched moulds of lower punch is behind upper cavity die and lower punch matched moulds, the thin plate moulding that just is stamped, this moment, upper cavity die was upwards got back to original position, waited for punching press next time, and lifter plate move upward under the effect of driving cylinder and drive by the guiding push rod workpiece place dull and stereotyped with and on shaping sheet move upward together, be convenient to take off shaping sheet, thereby finish the punching course of thin plate.This is simple in structure, easy to operate, easy installing/dismounting, and accurate positioning, stamping quality is high, floor space is little.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Structural representation when Fig. 2 is upper cavity die and lower punch matched moulds;
Fig. 3 is the structural representation after upper cavity die and lower punch divide mould;
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Referring to Fig. 1,2,3, sheet stamping device, this hydralic stamping press comprises workbench 1, be fixedly installed on the lower punch 2 of workbench 1 upper surface, and be positioned at the upper cavity die 3 that lower punch 2 tops cooperate with lower punch 2, this upper cavity die 3 is fixedly installed on the movable block 4 that can pump, workbench 1 below is provided with lifter plate 5, the upper surface of this lifter plate 5 is fixedly installed four guiding push rods 6, workbench 1 is passed in the upper end of guiding push rod 6, lower punch 2 is exposed at the top of lower punch, expose and be fixedly installed workpiece 10 on the guiding push rod of lower punch and place dull and stereotyped 7, this workpiece is placed dull and stereotyped 7 middle parts and is offered the resigning hole that passes for the punch on the lower punch, and being arranged on the driving cylinder 8 that workbench 1 below driving lifter plate 5 pumps, the expansion link upper end of this driving cylinder 8 is fixedly installed with the lower surface of lifter plate 5.
Wherein, be provided with guide pipe 9 in the through hole that workbench 1, lower punch 2 supply the guiding push rod to pass.Preferably, the guide pipe that arranges in the through hole that workbench passes for the guiding push rod for the guide pipe that arranges in the through hole that passes of guiding push rod and lower punch is same, reduces the wearing and tearing to the push rod that leads.
In the implementation, upper cavity die 3 adopts the connected mode of bolt or screw to be fixedly connected on movable block 4 lower surfaces.The upper end of guiding push rod 6 is placed dull and stereotyped 7 with workpiece and is adopted thread connecting mode to be connected.
