Abstract
The invention provides a double-toggle rod type four-hammer forging device, and belongs to the field of metal pressure processing machines. The device comprises an upper anvil block, a lower anvil block, an upper hammer, a lower hammer, a left side slide block, a right side slide block, a left side hammer and a right side hammer, and is characterized in that: double-toggle rod mechanisms are symmetrically arranged on left and right sides of the upper and lower anvil blocks respectively; each double-toggle rod mechanism consists of an oscillating rod, a connecting rod, a toggle rod and a guide rod, the upper end of the oscillating rod is hinged with a fixed point on the upper anvil block, and the lower end which is a movable point of the oscillating rod is hinged with the upper end of the connecting rod, the upper end of the toggle rod Z1 and the upper end of the toggle rod Z2 respectively; the lower end which is a movable point of the connecting rod is hinged with the upper end of the toggle rod Z3 and the upper end of the toggle rod Z4 respectively; the lower end of the toggle rod Z1 and the lower end of the toggle rod Z3 are hinged with the fixed point of the lower anvil block respectively; the lower end of the toggle rod Z2 and the lower end of the toggle rod Z4 are hinged with the fixed point on each side slide block respectively; the upper end of the guide rod is hinged with the fixed point on each side slide block; and the lower end of the guide rod is hinged with the fixed point of the lower anvil block. The device has the advantages that: sliding friction is changed into pivoting friction to reduce energy consumption and save energy; meanwhile, positions of the four hammers are changed along with the change of the diameter of a blank, the distances among the hammers can be regulated by changing the lengths and proportion of the connecting rods and the toggle rod mechanisms so as to regulate the diameter range of the forging blank.
Description
Technical field
The invention belongs to stress metal processing equipment field, be specifically related to a kind of duplex rod-type four tup forging apparatus.
Background technology
In recent years, along with the requirement of socio-economic development and environmental protection and energy saving, quick, efficient forging more and more seems important, especially to difficult-to-deformation material.The input of big press in addition, fully, effectively utilize high-power press, the workload that promotes big press also is the current domestic problem of needing solution badly.
Two tup extrusion billets were accomplished hammered work with transversely deforming vertically about the tradition free forging hydraulic machine just leaned on; Because it is low that transversely deforming not only pulls out efficient; And difficult distortion; Also as easy as rolling off a log face checking in transversely deforming; For this reason; Adopt up and down that the V-type anvil forges having aspect the flat-die forging anvil type, this pulling efficient than flat anvil two tup open die forgings up and down increases, and has the function that prevents face checking.V-type anvil size is certain, and is also constant to the workpiece contact point, and the pulling effect is limited.How can in deformation process, anvil shape change along with the variation of workpiece; Patent ZL 200780001312 " equipment for forging four-hammer " and patent ZL94223996.2 " two actives, two passive four tup forging machines " are installed in four forging hammers up and down on the support of inclined-plane and anti-abrasive disc; The forging hammer support is connected with the motion of side forging hammer support up and down; Forging hammer support and device activity crossbeam and stationary table up and down; The motion of upper ram relies on moved cross beam to drive, and the left and right side tup is driven by upper bracket through inclined-plane motion connection.The motion of lower ram realizes by press motion on above-mentioned two patents; The motion of two side tups leans on the inclined-plane of 40～50 degree to realize through last lower ram relative motion; The horizontal component of side tup produces by the inclined-plane; The size of horizontal component is subjected to the influence of the Area of bearing of tup operation; And whole process all is sliding friction; Frictional force is big, scope of operation lubricating requirement is harsh, and lubricant also is difficult to sealing.
Summary of the invention
The purpose of this invention is to provide a kind of duplex rod-type four tup forging apparatus, can overcome the shortcoming that prior art exists effectively.
The present invention realizes through following technical scheme:
As shown in Figure 1; It includes anvil block 4,11, last lower ram 5,10, left and right sides slide block 6,9, left and right sides tup 7,8 up and down; It is characterized in that in the left and right sides of anvil block 4,11 up and down dual-elbow-bar mechanism being installed symmetrically respectively, the structure of this dual-elbow-bar mechanism is to be that example is by fork 1, connecting rod 2, toggle link Z with the left side

The specific embodiment
As shown in Figure 1, this device is installed on the hydraulic press, following anvil block 11 is connected with stationary table, and last anvil block 4 is fixedlyed connected with moved cross beam.When last anvil block 11 of moved cross beam drive and upper ram 5 are exerted pressure downwards when starting hydraulic press; Drive left and right sides dual-elbow-bar mechanism and promote left and right sides slide block 6; 9 with left and right sides tup 7; 8 to the extrusion forging of blank center; Form up and down four tups simultaneously synchronously to the extrusion forging of blank center; Blank is owing to the effect of forging that is squeezed can only be out of shape vertically; Anvil block and upper ram upwards lifted on moved cross beam upwards lifted and drives subsequently; And left and right sides slide block and side tup draw back under the drive of left and right sides dual-elbow-bar mechanism; Next blank carries out next step in manipulator or other mode effect lower edge axial feeds or rotation and forges, and repeats to forge the pulling process of accomplishing whole blank like this.
