Abstract
The invention relates to a flash precise slicing hydraulic press used for the punching shear of a forging flash. The equipment combines a linear driving mechanism, a blank holding mechanism, a back pressure mechanism and a buffer device into novel special punching shear equipment. By adopting the linear unidirectional driving type of the equipment, a workpiece is only subject to a vertical unidirectional punching shear force, but not subject to a lateral force or an additional torsion in the punching-shear process; owning to the blank holding mechanism, the flash can not be warped in the punching-shear process as the flap edge is subject to a compulsive restraining force; owning to the back pressure mechanism, the forging is supported by a back pressure cylinder in the punching-shear process, and the flexible deformation of the forging is reduced; owning to the buffer device, the impact to the hydraulic system is avoided. The slicing hydraulic press which is provided by the invention can be used for the normal punching shear of the flash of the forging, and is especially suitable for the precise punching shear of the flap edge of the forging; the incision of the forging after punching shear has high precision and good quality. The invention can be suitable for all the enterprises which produce forgings.
Description
Affiliated technical field
The present invention relates to a kind of planning and cutting hydropress that is applicable to forging industry accurate punching forging flash.
Background technology
At present, also be not used in the special equipment of die-cut forging flash, generally use enclosed single-point (two point) crank press, fly press or common hydraulic press to be used for the die-cut of forging flash at forging industry.
On above-mentioned die cutting device, all there are not blank body and back-pressure mechanism, well-known, if there is not blank body, in die-cut process, the easy warpage of overlap causes the decline of decline of forging kerf quality and die life; If there is not back-pressure mechanism, forging is in vacant state in die-cut process, be easy to generate flexural deformation, causes forging precision to descend.
In addition, the work executing agency of closed type single point press and fly press has determined these two kinds of equipment and has not been suitable for the die-cut of forging flash, has not been suitable for the accurate punching of forging flash especially.We know that because closed type single point press adopts the toggle transferring power, when die-cut overlap, workpiece not only is subjected to the flush shear force perpendicular to overlap, and is parallel to the cross force of overlap, cause forging otch offsetting, coarse uneven; Cutting edge of die quick abrasion, life-span on the direction of cross force is low.Fly press is owing to adopt bolt and nut to pay executing agency's transferring power, when die-cut overlap, workpiece not only is subjected to the flush shear force perpendicular to overlap, and is parallel to the additional torque of overlap, causes that the forging otch is inhomogeneous, die point wearing and tearing inequality and life-span be low.Enclosed two point crank press complex structure, the cost height is difficult for applying.
Owing to reasons such as the influence of overlap warpage, cross force and additional torque and complex structures, above-mentioned three kind equipments all can't be applied to the accurate punching of forging flash.
Common hydraulic press is because slide block adopts straight line unidirectional drive mode, avoided closed type single point press and helical pressure chance to produce the defective of cross force and additional torque, but the problem on deformation of the warpage of overlap and forging does not solve, and common hydraulic press reduces to cause the impact of hydraulic system suddenly because of load when die-cut the end.
Summary of the invention
In order to overcome the deficiency of existing die cutting device, the invention provides a kind of new exclusive die cutting device, this equipment can reduce the distortion of forging greatly, improves the quality of forging precision and forging otch, prolongs the life-span of mould, can be used for the accurate punching of overlap.
The technical solution adopted for the present invention to solve the technical problems is: the advantage of using common slider of hydraulic press straight line unidirectional drive, increase blank body (on slide block, increasing flanging cylinder and blank holder) and back-pressure mechanism (at the inner counter pressure cylinder that increases of workbench) simultaneously, in addition, the impact of hydraulic system when alleviating die-cut finish, also can increase buffer unit, be combined into new exclusive overlap die cutting device, because this die-cut mode is similar to " planing tool " cutting of carpenter, so this equipment is named and is " precise planning and cutting hydropress ".
Because slide block has adopted straight line unidirectional drive mode, makes workpiece only be subjected to unidirectional vertical flush shear force in die-cut process, is not subjected to cross force and additional torque; Owing to adopted blank body, before die-cut overlap, earlier flanging cylinder and blank holder are compressed overlap, make overlap since be subjected to obligating power can't warpage in die-cut process; Owing to adopted back-pressure mechanism, forging is supported by counter pressure cylinder in die-cut process, is not to be in vacant state, thereby has reduced the flexural deformation of forging; Owing to be provided with buffer gear, the impact of hydraulic system is avoided in the decline rapidly of hydraulic pressure in the unexpected acceleration of slide block and the main hydraulic cylinder when utilizing little gap discharge opeing resistance to come that balance is die-cut to be finished.
Because the use of above-mentioned measure, the gap between forging and the die can reduce, and therefore the planning and cutting hydropress that the present invention relates to not only can be used for the common die-cut of forging flash, also can be used for the accurate punching (forging precision height, kerf quality is good) of forging flash.
