Embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not the reality the present invention
Apply scope limited to this.
As shown in Figure 1, Figure 2, Figure 3 shows, the long-armed spindle bending mould of the band of the present embodiment, including lower template 1, in
Template 2, cope plate 3 and Hydraulic Power Transmission System 4, the middle template are respectively arranged with upper guide bush 21, lower guide pin bushing 22 in both sides about 2,
The cope plate 3 is provided with the upper guide post 23 for stretching into the upper guide bush 21, and the lower template 1, which is provided with, stretches into the lower guide pin bushing 22
Lower guide pillar 24, the lower section of middle template 2 is provided with upper cavity die 5, and the cope plate 3 is provided through the curved of the middle template 2
Bent mould 6, the cope plate 3 are provided with the pull bar 7 for template in pull-up 2, and the pull bar 7 passes through drag link sleeve 8 and the upper mould
Plate 3 is slidably connected, and the lower template 1 is provided with lower cavity die 9.Scientific structure of the present invention, it is directed to device and is designed as the He of cope plate 3
Centering template 2 is oriented to lower template 1 simultaneously, improves the rigidity of guide pillar and guide pin bushing, the length for both having avoided guide pillars and bushes is long
The problem of easily producing bending, and can ensures the kinematic accuracy of mould, is advantageous to improve the geometry of armed knuckle forging
And dimensional accuracy.Overall compression correction is combined into a procedure with curved boom bending forming and completed by the present invention, can not only improve forging
Part quality, it can also improve more than the ﹪ of production efficiency 50;
The Hydraulic Power Transmission System 4 includes oil cylinder 41, low pressure fuel pump 42, check valve 43, high-pressure overflow valve 44, stop valve 45, the
One fuel tank 46, the second fuel tank 47, the 3rd fuel tank 49, the oil cylinder 41 are arranged at the upside of the middle template 2, the cope plate 3
Piston rod 48 corresponding with the oil cylinder 41 is provided with, first fuel tank 46 passes sequentially through low pressure fuel pump 42, check valve 43 connects
Oil cylinder 41 is passed to, the oil cylinder 41 is communicated to second fuel tank 47 by high-pressure overflow valve 44, and the 3rd fuel tank 49 passes through cut-off
Valve 45 connects with the oil cylinder 41.Hydraulic system employs low pressure fuel pump fuel feeding, high-pressure overflow valve produces the work of high-voltage oil liquid
Principle, it can be ensured that in whole bending forming process, forging is stably compressed, and this Hydraulic Power Transmission System is relative to high-voltage drive
System, energy consumption not only can be significantly saved, can also substantially save the manufacturing cost of system.
Further, the oil cylinder 41 is four, is distributed in the corner of the middle template 2.
Further, the spacing of the restricted downward storke of the bending die 6 is set between the cope plate 3 and middle template 2
Block 10, prevent bending die 6 is descending from forming excessive, damage product.
Further, the upper guide post 23, lower guide pillar 24 are solid by caging bolt and the cope plate 3, lower template 1 respectively
Fixed connection.
Further, it is provided with the die cavity for avoiding steering arm crooked route in the lower cavity die 9.
The present invention is in use, lower template 1 and cope plate 3 are separately fixed on the workbench of the column hydraulic presses of 6300kN tetra-
Below face and sliding block.During work, start hydraulic press and sliding block and cope plate 3 are lifted into upper limit position, now, four piston rods
48 are also at upper limit position with bending die 6, and upper and lower cavity plate is in open configuration, by trimming and the steering in higher temperature
Section is put into the impression of lower cavity die 9.
Pressing the operation button makes sliding block drive the parts that are fixed thereon stroke downwardly together, when upper cavity die 5 with it is recessed
When mould 9 is in contact, four oil cylinders 41 being fixed on above middle template 2 stop moving down, and are fixed on four above cope plate 3
Individual piston rod 48 and bending die 6 continue traveling downwardly, and caused oil pressure pressure makes upper cavity die 5 always compress forging, and bending die 6 is applied
The downward active force added makes the forearm bending forming of knuckle.
After bending forming terminates, sliding block upward stroke, first 6, four piston rods 48 of bending die and four pull bars 7 are to moving up
Dynamic, 2, four oil cylinders 41 of template and upper cavity die 5 are moved upwards up to upper limit position in then driving, now, upper cavity die 5 and lower cavity die
9 open, and push rod moves up ejects forging from the impression of lower cavity die 9, you can takes out forging, so far, a job follows
Ring terminates.
When particular manufacturing craft device is in original state and open configuration, the cavity of resorption of four oil cylinders 41 is full of fluid, when it is upper,
When lower cavity die closes, four oil cylinders 41 stay cool, when four piston rods 48 continue traveling downwardly with cope plate 3, lower intracavitary
Oil pressure steeply rises, and pressure oil drains into the second fuel tank 47 by high-pressure overflow valve 44, and the big I of its pressure passes through high pressure kicks
Valve 44 is adjusted；Four piston rods 48 and cope plate 3 move up during backhaul, and 2, four oil cylinders 41 of middle template etc. due to deadweight at
In lower outstanding position, now, with the rapid increase of the cavity of resorption volume of oil cylinder 41, pressure that the first fuel tank 46 is confessed by low pressure fuel pump 42
Cavity of resorption is full of rapidly by power oil.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention
Matter and scope.
