Technical field
The utility model belongs to the machine for press-bending metal sheet tool, especially relates to a kind of mould of numerical control electrohydraulic servo-type bending machine tool.
Background technology
Between the counterdie and die holder of the two flanging moulds in the existing sheet metal bending industry; basically counterdie all adopts the jacking of compression spring to reset; promptly after the sheet metal bending end of job between upper die and lower die or counterdie and the die shoe; the screen resilience pushing tow of the pressured spring that contracts of counterdie rises and resets; just can carry out the bending of next round then; but each pushing tow rises and resets; the compression spring all will be raised to highest order; counterdie also rises to highest order thereupon; so increased virtually counterdie press down bending the time the inoperative stroke, especially little workpiece to the bending drafts, idle work has increased; not only increased the consumption of power; and reduced production efficiency, in addition, compression spring height is big more; stability is poor more, just can reduce the precision of bending part finished product more.
Summary of the invention
The purpose of this utility model provides a kind of pneumatic pair of flanging sheet metal Bending Mould, can freely adjust the top lifting height of counterdie as required, and the jacking balance of movement reduces the idle work in the sheet metal bending operation effectively, further improves the precision of sheet metal bending productivity ratio and product.
The purpose of this utility model is achieved like this: a kind of pneumatic pair of flanging sheet metal Bending Mould, comprise patrix, counterdie, die holder, base plate and die holder holder, base plate is installed on the horizontal straight trough bottom land of die holder holder, the bottom cunning of die holder is contained in the horizontal straight trough of die holder holder and is packed on the base plate, the bottom of counterdie is then corresponding sliding to be contained in the jacking groove or jacking hole on body top at the bottom of the mould, patrix downwards in the V-shaped groove of counterdie bending workpieces or counterdie downwards on the plane, bottom right of counterdie and the die holder between the plane bending workpieces form two flanging bendings, it is characterized in that die holder segmentation along its length, the bottom of each section die holder is all slided in the horizontal straight trough that is contained in the die holder holder and is installed on the base plate, the counterdie of corresponding sliding dress segmentation in the jacking groove of each section die holder or jacking hole, the die holder of segmentation and the counterdie of segmentation can be by by assembly freely of the length of bending workpieces and assembly units; In addition, bottom at each section die holder, position corresponding to jacking groove or jacking hole, offer little and the vertical stepped hole that lower diameter is big of the upper diameter that communicates with it respectively, be arranged in each bottom large diameter hole, pneumatic cylinder be installed on base plate and the piston rod of each pneumatic cylinder is stretched out from the small diameter bore of top all and lean mutually with the baseplane of each section counterdie; Be positioned at a side of each pneumatic cylinder bottom simultaneously, offer shared air pipe passway in the bottom of each section die holder, in air pipe passway, lay corresponding the joining of porting of air inlet-outlet pipe and each pneumatic cylinder with ready-packaged joint, advance, the other end of blast pipe is connected with external air pump station is corresponding, air pump station has the numerical control travel control device, during bending work, press by the drafts of bending workpieces, regulate the best jacking stroke of pneumatic cylinder piston rod by the air pump station that has the numerical control travel control device, make counterdie be in best height and position, just can reduce the idle work of bender to greatest extent, boost productivity effectively and the precision of product.
A kind of pneumatic pair of flanging sheet metal Bending Mould that the utility model proposed, rational in infrastructure, safe and reliable, can freely adjust the top lifting height of counterdie as required, and jacking balance of movement, reduce the idle work in the bending operation effectively, further improve the precision of sheet metal bending productivity ratio and product.
Now the pneumatic pair of flanging sheet metal Bending Mould of in conjunction with the accompanying drawings and embodiments the utility model being carried is further described.
