Abstract
Description
Technical Field
[0001] The invention relates to the technical field of forging machine structures, in particular to a wire winding type free forging machine. Background Art
[0002] Free forging is a processing method that uses impact force or pressure to make the metal deform freely in all directions between the upper and lower anvil surfaces, without any restrictions, to obtain forgings with the desired shape, size and certain mechanical properties.
[0003] The load direction of free forging is changeable. The traditional prestressed tie rod frame structure maintains multi-directional stiffness balance through preload, reducing frame deformation caused by changes in load direction. At the same time, the moving beam of the press is driven by the hydraulic cylinder to reciprocate in the vertical direction. The four corners of the moving beam are wrapped around the column to form a closed force ring to resist the torque generated by the eccentric forging of the moving beam and prevent the frame from twisting or tilting. This multi-degree-of-freedom constraint structure can keep the moving beam in vertical motion, eliminate horizontal displacement and rotational degrees of freedom, disperse dynamic loads, and ensure forging accuracy.
[0004] The prestressed winding frame structure has a steel wire winding layer on the outside of the column that cannot withstand lateral extrusion. Therefore, the movable beam cannot construct a closed-loop guide mechanism that wraps the column. The column is not constrained on the outside in the horizontal direction. Under the action of cyclic loads, the column bends outward, and the anti-eccentric load capacity is reduced, affecting the forging accuracy. Summary of the invention
[0005] The technical problem to be solved by the present invention is that under the action of multi-directional eccentric load of free forging, the non-closed-loop guide structure of the wire winding frame has insufficient rigidity, the column is easily deformed, and the forging accuracy and stability are affected.
[0006] In order to solve the above problems, the present invention provides a free forging press that can improve the circumferential anti-eccentric load capacity of a wire winding press and add a reinforcement beam between four columns outside the moving beam. The specific solution is: A wire-wound free forging press comprises two arches which are detachably connected to each other. A steel wire rope is wound around each arch. An upper connecting layer and a lower connecting layer are respectively arranged between the top and the bottom of the two arches. A reinforcing beam assembly is arranged in the middle position between the two arches. A moving beam is arranged in the middle of the reinforcing beam assembly. A hydraulic assembly is arranged at the bottom of the upper connecting layer. The hydraulic assembly passes through the reinforcing beam assembly and is connected to the moving beam for driving the moving beam to move vertically based on the reinforcing beam assembly. A mold is placed on the lower connecting layer. When the moving beam moves to the bottom of the reinforcing beam assembly, the bottom of the moving beam abuts against the mold.
[0007] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: The present invention fixedly connects the tops and bottoms of two archways through an upper connecting layer and a lower connecting layer, and fixes a reinforcing beam assembly in the middle of the two archways, and connects four columns in a closed loop through the reinforcing beam assembly, thereby increasing the rigidity of the middle position of the frame, ensuring the horizontal stability of the moving beam under the action of multi-directional loads or eccentric loads, dispersing the load to prevent the column from twisting, and improving the forging accuracy; a moving beam is arranged in the middle of the reinforcing beam assembly, and a hydraulic assembly is arranged on the upper connecting layer, and the moving beam is driven by the hydraulic assembly to move vertically in the middle of the hollow reinforcing beam assembly, thereby pressing the material in the mold into a forging through the moving beam.
[0008] Preferably, a further technical solution of the present invention is: A single archway includes an upper crossbeam and a lower crossbeam, two columns are connected between the upper crossbeam and the lower crossbeam, and a reinforcement beam assembly is fixed in the middle of the four columns of the two archways. The frame structure of the single archway is formed by the upper crossbeam, the lower crossbeam and the two columns.
[0009] The reinforcement beam assembly includes a cover plate on the top and a connecting tube fixed at the bottom of the cover plate. The hydraulic assembly passes through the cover plate and is connected to the moving beam in the middle of the connecting tube. Guide belts are arranged at the four corners inside the connecting tube. Guide blocks matching the guide belts are arranged at the four corners of the moving beam. The moving beam is moved inside the connecting tube through the guide blocks and the guide belts, so that the moving beam can stably move vertically in the connecting tube.
[0010] The hydraulic assembly includes a working cylinder and a return cylinder. The working cylinder is fixed at the bottom of the upper connection layer, the piston rod of the working cylinder is connected to the top of the moving beam, the return cylinder is fixed on the cover plate, and the piston rod of the return cylinder is inserted and fixed inside the moving beam. The working cylinder drives the moving beam to press down, and the return cylinder drives the moving beam to move up.
[0011] The outer periphery of the upper cross beam, the outer side of the column and the outer periphery of the lower cross beam are all provided with steel wire grooves, in which steel wire ropes are wound to wind and fix the upper cross beam, the columns on both sides and the outer periphery of the lower cross beam. The steel wire ropes are used to increase the stability of the outer periphery of the upper cross beam, the columns and the lower cross beam.
[0012] The upper beams and lower beams of the two archways are fixedly connected by tension bolts. The tension bolts make the upper beam and the lower beam detachable, which is convenient for installation and transportation. BRIEF DESCRIPTION OF THE DRAWINGS
