Abstract
The invention discloses an accurate positioning device for quickly changing dies of a large hydropress. A sliding block and a work bench are respectively provided with four round positioning pin holes; a screw hole is arranged at the center of each round positioning pin hole; four rectangular positioning pin holes corresponding to the centers of the round positioning pin holes are respectively arranged on an upper die and a lower die and include two vertically arranged rectangular positioning holes and two horizontally arranged rectangular positioning pin holes; positioning pins are fixed in the round positioning pin holes; screws pass through the positioning pins and are screwed in the screw holes; the length edges of the rectangular positioning pin holes are large than the diameters of the excircles of the positioning pins and gaps are left between the width edges of the rectangular positioning pin holes and the excircles of the positioning pins. The invention can reduce the processing difficulty of die positioning, achieve high positioning accuracy during the change of the upper die and the lower die, and ensure the convenient and quick change of a damaged positioning device so as to ensure the quality of pressed products. The invention has the advantages of simple processing and convenient and easy operation.
Description
Technical field
The present invention relates to hydraulic press quick die change accurate positioning device, more specifically say the quick die change accurate positioning device that is applied on the large hydraulic press.
Background technology
At present known in quickly changing dies of large hydropress, what take is equiform locating pin structure up and down, and this structure is higher to the positioning requirements of upper/lower die, strengthens the difficulty that mould is made.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, the quickly changing dies of large hydropress accurate positioning device is provided, the accurate dowel device that detachably is convenient for changing in large hydraulic press, conveniently mold exchange more.
Solve the problem of prior art, the technical solution adopted in the present invention is:
The quickly changing dies of large hydropress accurate positioning device, slide block at hydraulic press is installed with mold, the workbench of hydraulic press is installed with bed die, described slide block, offer respectively four alignment pin circular holes on the workbench, the center of alignment pin circular hole has screw hole, at mold, have the rectangle dowel hole corresponding with the alignment pin center of circular hole on the bed die, four rectangle pin-and-holes are divided into two of vertically arranging and two of laterally arranging, be installed with alignment pin in the alignment pin circular hole, passed screw in the alignment pin and be screwed together in the screw hole, the long limit of rectangle dowel hole is greater than the alignment pin outside diameter, and broadside and alignment pin cylindrical leave the gap.
Described alignment pin is step-like, and it is oblate that the upper end is, and the lower end is circular, and the middle part offers installing hole, and screw placement is in installing.
The present invention is because the position of four rectangle dowel holes is orthogonal at left and right directions and fore-and-aft direction, to be matched in clearance between the flat limit of the long limit of rectangle dowel hole and alignment pin, broadside does not contact with alignment pin, so upper and lower mould is very convenient quick when die change is installed, how secondary mould is accurately located repeatedly, and be convenient for changing the alignment pin of damage.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention adopts dismountable alignment pin accurate positioning device that is convenient for changing, its great advantage is exactly to reduce the difficulty of processing of mould location, and make upper/lower die in replacing, can reach very high repetitive positioning accuracy, change easily and fast the positioner of damage, to guarantee the product quality of rolled-up stock.This structure processing is simple, easy to operate.
