Description
Technical field
The present invention relates to high speed stamping lathe height of packing compact adjustment structure; Relate in particular to lower die height adjusting device.
Background technology
In the prior art, forcing press is regulated height of packing compact and is mainly carried out in slide block.At present, most forcing presses all is this mode that adopts, and this mode has the form of two kinds of adjustings again, the one, adopt the worm and gear adjustment structure, the motion of drive ball screw, the distance between micro-adjusting slider and the bent axle reaches the purpose of regulating height of packing compact; The 2nd, adopt the adjusting screw(rod) screw bushing structure, purpose is the same with aforementioned manner.The shortcoming of these two kinds of structures all can make the risk that the weight of slide block moving part increases and increases oil leak, is difficult to satisfy the needs of lightweight of high-speed blanking press slide block and food, medical equipment processing industry.
Summary of the invention
The present invention is directed to above problem, a kind of press machine lower die height adjusting device that is arranged on the workbench is provided, being adjusted in of height of packing compact worked on the workbench carry out in the backing plate, the risk of having avoided the leakage of lubricating oil that workpiece is polluted simultaneously.
Technical scheme of the present invention is: it is fastened on counterdie on the workbench of forcing press, and it comprises and is used for fixing the following work backing plate that connects workbench, is used for fixing the work of the going up backing plate, piston, Adjusting bolt Adjusting screw, the runner that connect counterdie; Under the backing plate of working be provided with mesopore, the upper and lower end of mesopore is respectively equipped with stepped hole, piston top is provided with screw thread, the lower end of piston is provided with shoulder; Fixedly connected with last work backing plate in the upper surface of piston, Adjusting bolt Adjusting screw is by being threaded on the piston, the cylindrical of Adjusting bolt Adjusting screw and the upper end step hole flexible connection of work backing plate down, the shoulder of piston lower end and the lower end stepped hole flexible connection of work backing plate down are fixedly connected with runner on the cylindrical of Adjusting bolt Adjusting screw.
It also comprises hydraulic locking apparatus, the formed oil pocket in gap under hydraulic locking apparatus comprises between the end face of the periphery at end face, the surface of revolution and the Adjusting bolt Adjusting screw bottom surface of the mesopore of work backing plate, upper and lower end stepped hole, piston middle part, piston lower end shoulder, and the seal of oil circuit that communicates with oil pocket and the described oil pocket of sealing; Oil circuit is arranged on down on the work backing plate, and oil-out is arranged on down on the end face of lower end stepped hole of the backing plate of working.
The present invention has changed the gap of in the past adjusting between the mould can only be improved to the adjustment of counterdie height and position with the mould adjustment by the present situation that could realize with the height of adjusting patrix is adjusted in the slide position.But the work backing plate that counterdie is installed is set to two of relative motion, utilize piston, adjustment swivel nut to connect between the two, runner is set outside adjusting swivel nut adjusts the swivel nut rotation in order to drive, the rotation of adjusting swivel nut drives the axially-movable that piston is done above-below direction, thereby work backing plate and the variation of distance between the work backing plate down in the realization, and then the adjustment of realization counterdie height.For preventing the influence of alternating impulse load to transmission mechanism, the present invention also is provided with hydraulic locking apparatus, regulates screw thread in order to locking, prevents that relative motion produces mismachining tolerance in vibration.The present invention is arranged on the mold height adjusting device on the workbench, and the one, alleviated the weight of slide block, reduced driving load, the 2nd, avoided the pollution of lubricating oil to work piece, guaranteed security such as food, medical device product processing.
