Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments, is not reality of the invention
Scope limitation is applied in this.
As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment with long-armed spindle bending mould, including lower template 1, in
Template 2, cope plate 3 and Hydraulic Power Transmission System 4, middle about 2 two sides of template be provided with two groups be located at it is collinear
Upper guide bush 21, lower guide sleeve 22, the cope plate 3 are provided with the upper guide post 23 for protruding into the upper guide bush 21, and the lower template 1 is arranged
There is the lower guide post 24 for protruding into the lower guide sleeve 22, upper cavity die 5 is provided with below the middle template 2, the cope plate 3, which is provided with, to be worn
The bending die 6 of the middle template 2 is crossed, the cope plate 3 is provided with the pull rod 7 for template 2 in pull-up, and the pull rod 7 passes through
Drag link sleeve 8 is slidably connected with the cope plate 3, and the lower template 1 is provided with lower cavity die 9.Structure of the invention science, guiding is filled
It installs and is calculated as cope plate 3 and lower template 1 guiding of centering template 2 simultaneously, improve the rigidity of guide post and guide sleeve, both avoid guide post
With length too long the problem of being easy to produce bending of guide sleeve, and the kinematic accuracy of mold can ensure that, be conducive to improve armed and turn to
Save the geometry and dimensional accuracy of forging.The present invention whole will compress correction, and with curved boom bending forming to be combined into a procedure complete
At forging quality not only can be improved, 50 ﹪ or more of production efficiency also can be improved.
The Hydraulic Power Transmission System 4 includes oil cylinder 41, low pressure fuel pump 42, check valve 43, high-pressure overflow valve 44, shut-off valve
45, the first fuel tank 46, the second fuel tank 47, third fuel tank 49, the oil cylinder 41 are set to the upside of the middle template 2, it is described on
Template 3 is provided with piston rod 48 corresponding with the oil cylinder 41, and first fuel tank 46 passes sequentially through low pressure fuel pump 42, check valve
43 are connected to oil cylinder 41, and the oil cylinder 41 is connected to second fuel tank 47 by high-pressure overflow valve 44, and third fuel tank 49 passes through
Shut-off valve 45 is connected to the oil cylinder 41.Hydraulic system uses low pressure fuel pump fuel feeding, high-pressure overflow valve generates high-voltage oil liquid
Working principle, it can be ensured that in entire bending forming process, forging is steadily compressed, and this Hydraulic Power Transmission System is relative to high pressure
Transmission system, not only can substantially energy saving, can also obviously save the manufacturing cost of system.
Further, the oil cylinder 41 is four, is distributed in the quadrangle of the middle template 2.
Further, the limit of restricted 6 downward storke of the bending die is set between the cope plate 3 and middle template 2
Block 10 prevents 6 downward storke of bending die excessive, damages product.
Further, the upper guide post 23, lower guide post 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, is set in the lower cavity die 9
Be equipped with the die cavity for avoiding steering arm crooked route, when the bending die 6 comes downwards to minimum point, the bending die 6 with it is described recessed
Steering arm extrusion pressing type chamber is formed between mould 9.
The present invention is in use, lower template 1 and cope plate 3 are separately fixed on the workbench of tetra- column hydraulic press of 6300kN
Below face and sliding block.When work, starts hydraulic press and promote sliding block and cope plate 3 to upper limit position, at this point, 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 in the steering of higher temperature
Section is put into the impression of lower cavity die 9.
Pressing the operation button makes sliding block that the components that are fixed thereon be driven to move downwardly together, when upper cavity die 5 with it is recessed
When mould 9 is in contact, four oil cylinders 41 stopping being fixed on above middle template 2 is moved down, and is fixed on four above cope plate 3
A piston rod 48 and bending die 6 continue traveling downwardly, and generated oil pressure pressure compresses upper cavity die 5 by forging always, and bending die 6 is applied
The downward active force added makes the forearm bending forming of knuckle.
After bending forming, sliding block upward stroke, first 6, four piston rods 48 of bending die and four pull rods 7 are to moving up
Dynamic, then 2, four oil cylinders 41 of template and upper cavity die 5 are moved upwards up to upper limit position in drive, at this point, upper cavity die 5 and lower cavity die
9 open, and mandril is moved up ejects forging from the impression of lower cavity die 9, can take out forging, and so far, a job follows
Ring terminates.
When particular manufacturing craft device is in original state and open configuration, the cavity of resorptions of four oil cylinders 41 is full of oil liquid, when it is upper,
Lower cavity die be closed when, four oil cylinders 41 stay cool, when four piston rods 48 are continued traveling downwardly with cope plate 3, under it is intracavitary
Oil pressure steeply rises, and pressure oil drains into the second fuel tank 47 by high-pressure overflow valve 44, and the size of pressure can pass through high pressure kicks
Valve 44 is adjusted；Four piston rods 48 and cope plate 3 move up when backhaul, and 2, four oil cylinders 41 of middle template etc. due to self weight at
In lower outstanding position, at this point, increasing rapidly with 41 cavity of resorption volume of oil cylinder, the first fuel tank 46 passes through the pressure that low pressure fuel pump 42 is confessed
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 range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
