Description
Technical field
The present invention relates to machining equipment, in particular to a kind of Multi-head punching machine bed.
Background technology
Punch press is that the compressed air (or hydraulic oil) utilizing compressed air pump (or hydraulic pump) to provide enters cylinder through magnetic valve, driving in piston drive to main shaft makes main shaft formation move downward, thus formation impulse force, make workpiece produce the distortion of regulation in a mold and reach the object of processing.The punch press of prior art only has a drift, can only dull make a call to a hole, and can not distance accurately between determining hole and hole, not easily weighs and designs hole knockout.In addition, the punch press in prior art with a drift adopts manual operation usually, complicated operation, require that operating personnel possess higher technical merit, but operating efficiency is lower.
Summary of the invention
Technical problem solved by the invention: the punch press in prior art with a drift, once can only make a call to a hole, and can not distance accurately between determining hole and hole.
The invention provides following technical scheme:
A kind of Multi-head punching machine bed, comprises frame, upper modular system, lower modular system; Described upper modular system and lower modular system are arranged in frame;
Described upper modular system comprises mold and mold drive system, and described mold is arranged in mold drive system, described mold drive systems mold straight line lifting;
Described lower modular system comprises and the bed die of mold quantity and respective outer side edges and bed die supporter, and described bed die is arranged on bed die supporter;
The quantity of described mold is at least two, and described at least two mold horizontal cross are distributed in mold drive system;
Single bed die comprises die shoe, counterdie, end face offers counterdie installing hole with described die shoe, described die shoe side sets out tailing mouth, described go out tailing mouth pass through tailing passage and be communicated with counterdie installing hole, described go out tailing passage comprise Vertical Channel portion and ramp way portion, cross section, described Vertical Channel portion is circular, the cross section in described ramp way portion is square, described counterdie is circular, described counterdie is embedded in counterdie installing hole, and inner diameter values circle in described Vertical Channel portion is between counterdie installing hole inner diameter values and counterdie inner diameter values.
By technique scheme, Multi-head punching machine bed of the present invention once up and down matched moulds can complete at least two punching processing simultaneously, and can distance accurately between determining hole and hole.Tailing after punching is cut discharges die shoe through going out tailing passage by going out tailing mouth, owing to going out inner diameter values circle in the Vertical Channel portion of tailing passage between counterdie installing hole inner diameter values and counterdie inner diameter values, therefore, tailing successfully can all enter Vertical Channel portion, then flows into ramp way portion.The matching design in described Vertical Channel portion and ramp way portion, can make the first vertical drop of tailing, then discharge tailing mouth through ramp way portion, so, can improve the discharge capacity tailing passage, prevention tailing overstocks in tailing passage.
As to above-mentioned go out the supplementary notes of tailing passage, described in go out the Vertical Channel portion center line of tailing passage, ramp way portion center line, counterdie center line are in the same vertical plane.Design like this, can make tailing discharge tailing mouth through distance short as far as possible, to prevent tailing going out in tailing passage to overstock.Improve as one, described in go out tailing mouth and be opened on die shoe side, and be positioned on the boundary line of described side and die shoe bottom surface, so, tailing passage can be used and trend towards vertical shape as far as possible, to improve its discharge capacity.
As the one explanation of the present invention to upper modular system, described mold drive system comprises crown wall plate, oil cylinder, mono-Oscillating arm, first vertical connecting rod, cornice sheathing, a pair slide rail, described crown wall plate is fixedly mounted in frame, described crown wall plate is vertically arranged, one end of described oil cylinder is articulated on crown wall plate, the other end is Yu the upper end thereof of mono-Oscillating arm, the lower end of described mono-Oscillating arm is provided with a hinge hole and a pivoted hole, described mono-Oscillating arm lower end is articulated on crown wall plate by pivoted hole, described mono-Oscillating arm lower end is by the upper end thereof of hinge hole and the first vertical connecting rod, the lower end of the described first vertical connecting rod is articulated on cornice sheathing, described cornice sheathing vertically arranges and is positioned at the below of crown wall plate, described a pair slide rail is fixedly mounted in frame, described a pair slide rail coordinates with the both end sides of cornice sheathing, for leading to the lifting of cornice sheathing, described mold is arranged on the baseplane of cornice sheathing.By technique scheme, described cylinder action, driving mono-Oscillating upper-arm circumference to swing certain angle mono-Oscillating arm around itself and crown wall plate articulated section drives the first vertical connecting rod hinged with it to move down, first vertical connecting rod drives cornice sheathing to move down under the guiding of a pair slide rail, be arranged on the mold on cornice sheathing baseplane and bed die matched moulds, punching processing is completed to the workpiece be seated on bed die.The driving force of Multi-head punching machine bed of the present invention derives from oil cylinder, without the need to manual operation, simple to operation, is conducive to the raising of operating efficiency.Wherein, described oil cylinder is by oil pump station fuel feeding, and described oil pump station is positioned at by the side of oil cylinder, and described oil pump station is arranged on horizontal stand, and described horizontal stand is arranged in frame.
