Description
Technical field
The utility model relates to a kind of circular arc anvil that forges, particularly a kind of simple in structure, locate forging circular arc anvil reliable, applied widely.
Background technology
Forging is that one utilizes metal forming machinery to exert pressure to metal stock, makes it produce plastic deformation to obtain the processing method with certain mechanical performance, definite shape and size forging, one of two large parts of forging and stamping (forging and punching press).Can eliminate the defects such as cast condition that metal produces in smelting process is loose by forging, optimize heterogeneous microstructure, simultaneously owing to having preserved complete metal streamline, the mechanical performance of forging is generally better than the foundry goods of same material.The strength member that in associated mechanical, load is high, condition of work is severe, except sheet material, section bar or the weldment of the better simply available rolling of shape, adopts forging more.
Current large-scale columnar workpiece, in the time forging, all adopts open die forging, and it controls the shape and size of forging by manual operation, so forging precision is low, allowance is large, and labour intensity is large, and productivity ratio is not high yet.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, locate forging circular arc anvil reliable, applied widely.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of circular arc anvil that forges, and its innovative point is: comprise the upper and lower mould bases of U-shaped, between the top of described lower mold holder and top mold frame, be provided with hydraulic cylinder device; In described lower mold holder, U-shaped bottom end face is fixedly connected with the counterdie of open semicircle shape cavity, in described top mold frame, U-shaped bottom end face is fixedly connected with the patrix of open semicircle shape cavity, the chimeric connection of described upper and lower mould bases, described upper and lower mould bases joint face place is provided with guide post along hydraulic cylinder direction, be provided with butterfly with the upper and lower mould frame end face of upper and lower mould fixed connection place, also comprise backing plate, described backing plate is arranged between upper and lower mould frame contact-making surface.
On this basis, the structure of described top mold frame is: described top mold frame comprises in-line member and 4 baffle arrangements, described baffle arrangement forms the dual-side of U-shaped structure, described baffle arrangement is positioned at four angles of an end face of in-line member, described baffle arrangement and the moulding of in-line structural entity form, and the region division between described baffle plate has guide post groove and hydraulic cylinder push rod container cavity.
On this basis, the structure of described lower mold holder is: described lower mold holder comprises the portion of inlaying and U-shaped member, the described portion of inlaying is the structure similar with top mold frame baffle arrangement, the described portion of inlaying is provided with the hydraulic cylinder container cavity corresponding with top mold frame and guide post groove, described hydraulic cylinder container cavity bottom sidewall is connected with fluid pressure line, and it is external that described fluid pressure line converges at a pipeline.
The utility model has the advantage of: when forging, workpiece is placed between upper and lower mould, utilize the slide block of press to impact top mold frame, make upper and lower mould matched moulds extruding workpiece, after slide block is up, top mold frame and patrix reset under the effect of hydraulic cylinder device, realize die sinking; Slide block is descending forging again, so repeatedly, thereby workpiece rapid forge is become to require shape.
Hydraulic cylinder device, the design of guide post and backing plate makes it possible to control flexibly the aperture of upper and lower mould, is suitable for the workpiece of different size, and the scope of application is wider, has also guaranteed in addition the reliability of upper and lower mould bases location.
Brief description of the drawings
Fig. 1 is that the utility model forges circular arc anvil structural representation.
Fig. 2 is that the utility model forges circular arc anvil side structure schematic diagram.
Detailed description of the invention
The utility model forges circular arc anvil and comprises lower mold holder 1, top mold frame 2, hydraulic cylinder device 3, fluid pressure line 4, guide post 5, backing plate 6, butterfly 7, baffle arrangement 8, patrix 9, counterdie 10, guide post groove 11, hydraulic cylinder push rod container cavity 12, inlays portion 13, hydraulic cylinder container cavity 14.
As shown in Fig. 1 Fig. 2, the utility model forges circular arc anvil and comprises the mould bases up and down taking the shape of the letter U, and between the top of lower mold holder 1 and top mold frame 2, is provided with hydraulic cylinder device 3; The interior U-shaped bottom end face of lower mold holder 1 is fixedly connected with the counterdie 10 of open semicircle shape cavity, the interior U-shaped bottom end face of top mold frame 2 is fixedly connected with the patrix 9 of open semicircle shape cavity, the upper and lower chimeric connection of mould bases, upper and lower mould bases joint face place is provided with guide post 5 along the direction of hydraulic cylinder device 3, be provided with butterfly 7 with the upper and lower mould frame end face of upper and lower mould fixed connection place, also comprise backing plate 6, this backing plate 6 is arranged between upper and lower mould frame contact-making surface; The benefit of this structure is: guide post 5 be arranged so that the top mold frame unlikely sideslip that is in operation, location is reliable, adding of butterfly 7 also stoped the offsetting of upper and lower mould with upper and lower mould bases fore-and-aft direction, the setting of backing plate 6 more makes the scope of application of the utility model forging circular arc anvil wider in addition, can realize by the number of increase and decrease backing plate 6 increase of the range of work.
