A double-knuckle-type four-hammer forging device belongs to the field of metal pressure processing machinery, including upper and lower anvils, upper and lower hammers, left and right sliders, and left and right hammers. The feature is that the double toggle mechanism is symmetrically installed on the left and right sides of the upper and lower anvil respectively. The double toggle mechanism is composed of a swing rod, a connecting rod, a toggle rod and a guide rod. The lower end is hinged with the upper end of the connecting rod, toggle Z 1 , Z 2 respectively, the lower end of the connecting rod is hinged with the upper end of the toggle Z 3 , Z 4 respectively, and the toggle Z 1 , Z 3 The lower ends are respectively hinged with the fixed points of the lower anvil, the lower ends of the toggle rods Z 2 and Z 4 are respectively hinged with the fixed points on the side slider, the upper end of the guide rod is hinged with the fixed point on the side slider, and the lower end is hinged with the lower anvil The seat fixed point is hinged. The advantage is that sliding friction is changed into rotational friction, which reduces energy consumption and saves energy. At the same time, the positions of the four hammerheads change with the diameter of the billet, and the length and ratio of the connecting rod and the toggle mechanism can be changed to adjust the distance between the hammerheads, adjust the diameter range of the forging billet, and expand the scope of use.
Description
Technical field
The invention belongs to stress metal processing equipment field, be specifically related to a kind of Double-toggle rod type four hammer forging devices.
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 in addition input of large press, fully, effectively utilize high-power press, the workload that promotes large press also is the problem that Present Domestic is needed solution badly.
The tradition free forging hydraulic machine is that top lower two tup extrusion billets are finished hammered work with transversely deforming vertically, not only drawing efficiency is low owing to transversely deforming, and difficult distortion, as easy as rolling off a log face checking in transversely deforming also, for this reason, adopt up and down that the V-type anvil forges having aspect the flat-die forging anvil type, this drawing efficiency 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 friction-proof piece, forging hammer support is connected with the motion of side forging hammer support up and down, forging hammer support and device activity crossbeam and workbench are fixed 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 by inclined-plane motion connection.The pressured machine of motion of lower ram moves to realize on above-mentioned two patents, the motion of two side tups realizes by upper lower ram relative motion by the inclined-plane of 40～50 degree, the horizontal component of side tup produces by the inclined-plane, the size of horizontal component is subjected to the impact of the Area of bearing of tup operation, and whole process all is sliding friction, frictional force is large, 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 Double-toggle rod type four hammer forging devices, can effectively overcome the shortcoming that prior art exists.
The present invention is achieved through the following technical solutions:
As shown in Figure 1, it includes up and down anvil block 4,11, upper lower ram 5,10, left and right sides slide block 6,9, left and right sides tup 7,8, it is characterized in that in anvil block 4 up and down, 11 the left and right sides dual-elbow-bar mechanism being installed symmetrically respectively, the structure of this dual-elbow-bar mechanism be take the left side as example be by fork 1, connecting rod 2, toggle link Z

Be hinged, the fixing point D on lower end and the lower anvil block 11 is hinged.Advantage of the present invention and good effect are: the change sliding friction is pivoting friction, can greatly reduce energy consumption, saves the energy.Simultaneously, the position of having realized four tups changes automatically along with the vary in diameter of blank, can also change the length of connecting rod and elbow-bar mechanism and ratio and adjust distance between tup, adjust the diameter range of forging blank, enlarged device the scope of application, increased the versatility of equipment.
Description of drawings:
Fig. 1 is the structural representation of Double-toggle rod type four hammer forging devices; Left-half is opening, and right half part is closure state, left-right symmetry, and structure is identical.Among the figure:

The specific embodiment
As shown in Figure 1, this device is installed on the hydraulic press, lower anvil block 11 is fixedly connected with workbench, and upper anvil block 4 is fixedly connected with moved cross beam.When the upper 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 and 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 pull open under the drive of left and right sides dual-elbow-bar mechanism, next blank vertically feeding or rotation under manipulator or other mode effects carried out next step and forged, and repeats like this to forge the pulling process of finishing whole blank.
