Description
Technical field
The utility model relates to punching die, especially relates to pneumatic composite punching mould tool.
Background technology
In automobile manufacture industry,, need carry out elaboration optimization to some vehicles at different customer requirements, thereby need be to outward appearance stamping parts (the left and right sides position outside plate of some vehicles, the tailgate inner panel, products such as left and right daughter board) establish change, increase some new parts installing holes.These installing hole required precision height, position be complicated (product is on a plurality of curved surfaces), and the compound mode in hole needs to switch.Usually the mode of taking is original punching die to be established become or newly-increased 1-2 cover punching die.In addition, traditional punching die type of drive adopts main equipments such as press machine, complex structure, and it is very big to take up room; Because newly-increased hole is arranged on a plurality of curved surfaces of product, 3 groups of above switchings of Kong Weixu, the punching direction is compound direction, even the direction of opposition, so mould establishes change and interference can occur, even influences the structure of original mould, can't satisfy the use needs.And newly-increased mould design difficulty is big, and cost is higher, and the construction cycle is long, and precision is difficult to guarantee, also can causes the stamping machine machine utilization too high.
Summary of the invention
The utility model purpose be to provide a kind of simple in structure, easy to operate, take up room little, the pneumatic composite punching mould tool that production efficiency is high.
For achieving the above object, the utility model can be taked following technical proposals:
Pneumatic composite punching mould tool described in the utility model comprises upper and lower template, is separately positioned on protruding, die body on the described upper and lower template, and is arranged on the guiding mechanism between the upper and lower template; Above cope match-plate pattern, be provided with cylinder body, be provided with upper piston, lower piston, shoe cream room, working oil chamber, working piston from top to bottom at described inner chamber of cylinder block; Between described upper and lower piston, be provided with compression spring; Be fixed with push rod vertically downward at the upper piston middle part, the through hole that the lower piston middle part is passed in described pusher slide movable sealing extends in the described shoe cream room; Between described shoe cream room and working oil chamber, be provided with flow-guiding channel; Offer blind hole vertically downward in the working piston upper surface middle part, the aperture of described blind hole is connected with working oil chamber; Be provided with the ring platform that cooperates with the inboard wall of cylinder block slipper seal at working piston outer peripheral face middle part cylinder body is divided into upper and lower piston chamber; The lower end slipper seal of working piston extend outside the cylinder body and with the blind hole suit that is opened in the cope match-plate pattern upper surface; Be provided with the supercharging air chamber at the cylinder body that is positioned at upper piston top, described supercharging air chamber is communicated with described upper piston chamber by the two-bit triplet solenoid directional control valve; Described upper and lower piston chamber is communicated with two work gas ports of two five-way solenoid directional control valves respectively.
The utility model advantage is to have changed tradition and utilizes press machine to drive the mould mode.Mold mechanism is self-powered, and product is carried out stamping-out.By moving downward of lower piston, hydraulic oil is divided into shoe cream room and two zones of working oil chamber, the proportional output hydraulic oil of hydraulic oil that these two zones are sealed makes the working piston motion, thereby drives the drift stamping-out product that cope match-plate pattern promotes the punch body.In addition,, can guarantee the stamping-out direction of drift exactly, realize multi-faceted product being carried out compound punching easily by adjusting the setting angle of a plurality of pneumatic composite punching mould tool cylinder bodies described in the utility model.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, pneumatic composite punching mould tool described in the utility model comprises upper and lower template 1,2, is separately positioned on protruding, die body 3,4 on the described upper and lower template 1,2, and is arranged on the guiding mechanism 5 between the upper and lower template 1,2; Above cope match-plate pattern 1, be provided with cylinder body 6, be provided with upper piston 7, lower piston 8, shoe cream room 9, working oil chamber 10, working piston 11 from top to bottom at described cylinder body 6 inner chambers; Between described upper and lower piston 7,8, be provided with compression spring 12; Be fixed with push rod 13 vertically downward at upper piston 7 middle parts, the through hole that lower piston 8 middle parts are passed in described push rod 13 slipper seals extends in the described shoe cream room 9; Between shoe cream room 9 and working oil chamber 10, be provided with flow-guiding channel 14; Offer blind hole 15 vertically downward in working piston 11 upper surface middle part, the conical orifice of described blind hole 15 is connected with working oil chamber 10; Be provided with the ring platform that cooperates with cylinder body 6 inwall slipper seals at working piston 11 outer peripheral faces middle part cylinder body 6 is divided into upper and lower piston chamber 16,17; The lower end slipper seal of working piston 11 extend outside the cylinder body 6 and with the blind hole suit that is opened in cope match-plate pattern 1 upper surface; Be provided with supercharging air chamber 18 at the cylinder body 6 that is positioned at upper piston 7 tops, described supercharging air chamber 18 is communicated with described upper piston chamber 16 by two-bit triplet solenoid directional control valve 19; Described upper and lower piston chamber 16,17 is communicated with two work gas ports of two five-way solenoid directional control valves 20 respectively.
The utility model operation principle is summarized as follows:
1, the holding pad casting die stage: two five-way solenoid directional control valves 20 start, and compressed air enters upper piston chamber 16,17 exhausts of lower piston chamber.Working piston 11 moves downward under the effect of F.F. Pneumatic pressure fast, the holding pad 21 that drives cope match-plate pattern 1 promotion punch body 3 touches after the product 22 that is placed on the die body 4, compression along with compression spring 12, holding pad 21 on the punch body 3 continues the descending product 22 of pushing down, working piston 11 stop descending and lower piston under compression spring 12 effect, the hydraulic oil in the shoe cream room 9 is squeezed in the working oil chamber 10.
