Abstract
A hydraulic clamp for clamping plates relates to a plate clamp in numerical controlled plate processing. The utility model consists of a clamp body, a hydraulic system, a controller, a hydraulic cylinder and a piston. Within the hydraulic cylinder is located a two-phase pistons with their piston rods being connected with the clamp body respectively. Within said piston rods are located an axial hole, one end of the said axial hole being through the piston, the other end being connected with an air compressor. Said two pistons with through rod concavities communicate with the hydraulic system. The air compressor is connected with the controller. The oil concavities of two pistons of the hydraulic clamp are communicated with each other, being floating upward and downward while in stable clamping adaptable to form changes of warping plates. at clamping, when one piece of the clamp bocy contacts plates, said clamp piece gets resistance, then the other clamp piece serves fast feed, thereby realizing adaptable clamping of plates; at material returning, compressed gas is applied for fast restoration. The utility model is especially applicable for clamping hot rolling thick plates requiring low precision.
Description
Technical field
The utility model relates to a kind of hydraulically operated fixture, relates in particular to a kind of plate clamp of digital control plate processing equipment.
Background technology
When some thicker heat of processing were pricked sheet material, because these slabs have metabolies such as warpage, distortion, sometimes, when sheared edge entered the edge of a knife, clamping place and the edge of a knife were not easy to realize mechanical grip during shearing not on a horizontal plane.The hydraulic clamp of fixed position, clamp sheet material after, processing the limit since warpage can't enter the edge of a knife.Therefore, when thicker heat bundle plate is sheared, need personnel to assist charging, personnel's labour intensity is big, and working (machining) efficiency is low.
Summary of the invention
Of the present utility modelly provide a kind of hydraulic tongs that can adapt to the clamping plate with float function of blank shape automatically at above defective.
The technical solution of the utility model is: be made up of caliper, hydraulic system, controller, hydraulic cylinder, piston, in hydraulic cylinder, establish two in opposite directions pistons, the piston rod of two-piston links to each other with caliper respectively, be provided with the hole coaxial in the piston rod with piston rod, one end in hole runs through piston, one end links to each other with air compressor machine, and the rod chamber of two-piston links to each other and is communicated with hydraulic system, and air compressor machine connects controller.
Two calipers are provided with the guide post of a control caliper direction of motion, and guide post is parallel to hydraulic cylinder.
Be respectively equipped with the adjusting bolt on the tong arm of caliper.
The oil pocket of hydraulic tongs two-piston of the present utility model is communicated with, and can fluctuate in firm grip, to adapt to the change of shape of buckling deformation plate; When clamping, when wherein a caliper touched plate, this caliper was subjected to resistance, and another caliper fast feed has realized the adaptability clamping for plate; During the material returned, adopt Compressed Gas to reset, speed is fast.Hydraulic tongs of the present utility model is specially adapted to the clamping that the lower heat of precision is pricked slab.
