The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The invention discloses a kind of inaccessible formula multiway forging device and forge precision, reduce or avoid the generation of substandard products, increase work efficiency the purpose that reduces production costs to reach effective assurance.
Embodiment 1
As shown in Figure 1, 2, a kind of inaccessible formula multiway forging device comprises frame 1, is used for the mould 2 of shaped article and is fixedly set on the frame 1 and acts on hydraulic transmission on the mould 2; Hydraulic transmission comprises the master cylinder 3 that is arranged at mould 2 tops, is arranged at the lateral compression oil cylinder 5 that mould 2 belows are used for the liftout oil cylinder 4 of blanking and are used for the lateral compression shaping workpiece, lateral compression oil cylinder 5 is 2, and lateral compression oil cylinder 5 rear ends are provided with the moving element that can move along lateral compression oil cylinder 5 inwalls; Frame 1 comprises the support 6 that is used for support fixation lateral compression oil cylinder 5, and the outside and successively that a plurality of moving elements are the fixedly connected securing member that are wire-wrapped in each moving element, and securing member is airtight loop configuration.
By rear end moving element is set at the lateral compression oil cylinder, and make moving element fixedly connected with securing member, when each lateral compression oil cylinder carries out squeezing action to workpiece, the power that reacts on the frame can directly act on the securing member, because securing member is airtight loop configuration, guarantees that securing member is subjected to equilibrium of forces everywhere, effectively improved the forging precision, reduce or avoid the generation of substandard products, increase work efficiency, reduced production cost.
Support 6 is fixedlyed connected with the sidewall of lateral compression oil cylinder 5.The reaction force of lateral compression oil cylinder 5 bottoms generation can not directly act on the support 6 like this, guarantees the stability of support, prevents that it from producing distortion, and influence is processed and forged precision.
Moving element is that an end stretches into lateral compression oil cylinder 5 inboard ends and stretches out the outer bonnets 11 of fixedlying connected with securing member of lateral compression oil cylinder 5.The ring support 12 that securing member is formed in one.When the lateral compression oil cylinder does work, the reaction force that produces will promote bonnet 11 and move, because ring support 12 is wire-wrapped in bonnet 11 outsides, then bonnet 11 can be given ring support 12 with force transmission, make the force balance of each lateral compression oil cylinder generation by ring support, power does not act on above the frame, has reduced the load-bearing requirement of frame, has simplified the structure of frame.Guarantee the machining accuracy of workpiece, enhance productivity, reduce production costs.
Embodiment 2
As shown in Figure 3, all the other are identical with embodiment 1, and difference is, lateral compression oil cylinder 5 is uniform 3, moving element is the lower piston 21 that is arranged at lateral compression oil cylinder 5 inboards, and lower piston 21 is provided with connecting rod 22, and connecting rod 22 stretches out lateral compression oil cylinder 5 outsides and securing member is fixed.Securing member is polygonal framework 23, or is Wrapping formed steel band 24 or steel wire rope, or is the outside polygonal framework 23 that is wound with steel band 24 or steel wire rope.Framework 23 is a triangular framing, is connected to moving element in the securing member.When 5 actings of lateral compression oil cylinder, the reaction force that produces will promote lower piston 21 and move with connecting rod 22, owing to be connected to connecting rod in the framework, then connecting rod can directly act on active force on the framework 23, make the force balance of each lateral compression oil cylinder generation by framework, power does not act on above the frame, has reduced the load-bearing requirement of frame, has simplified the structure of frame.Guarantee the machining accuracy of workpiece, enhance productivity, reduce production costs.
By arranged outside steel band or steel wire rope at framework, improve the intensity of framework, avoid framework to produce distortion, in addition, except that adopting steel band or wire cable strengthening framework, also can on framework, fixedly install reinforcement etc., specific constructive form does not limit.
In addition to the implementation, the quantity of lateral compression oil cylinder can be 4,5 or a plurality of, and the shape of framework can be designed to polygonized structure according to the quantity of lateral compression oil cylinder, specifically needs to decide on workpiece processing.
Inaccessible formula multiway forging device disclosed by the invention comprises frame, is used for the mould of shaped article, and hydraulic transmission; The master cylinder that described hydraulic transmission comprises, liftout oil cylinder and lateral compression oil cylinder, described lateral compression oil cylinder is at least 2, described lateral compression oil cylinder rear end is provided with the moving element that can move along described lateral compression oil cylinder inner wall; Described frame comprises the support that is used for the described lateral compression oil cylinder of support fixation, and be wire-wrapped in described each moving element the outside and successively with the fixedly connected securing member of described a plurality of moving elements, described securing member is airtight loop configuration.The present invention is provided with moving element by the rear end at the lateral compression oil cylinder, and make moving element fixedly connected with securing member, when each lateral compression oil cylinder carries out squeezing action to workpiece, the power that reacts on the frame can directly act on the securing member, because securing member is airtight loop configuration, guarantees that securing member is subjected to equilibrium of forces everywhere, effectively guaranteed the forging precision, reduce or avoid the generation of substandard products, increase work efficiency, reduced production cost.
