Description
Technical field:
The utility model relates to the machine for rolling ring rolling technical field, a kind of machine for rolling ring isolated plant of rolling asymmetric special-shaped ring.
Background technology:
Asymmetric special-shaped ring is a kind of strength member on the Solid Rocket Motor combustion chamber housing.Because will bear high temperature and high pressure during its work, the stability of its structure and performance can directly have influence on the technology and the tactics index of rocket, so proposed very complicated requirement for the production technology of this part; This part at initial stage, its awl tube encircles assembly welding again for roll of steel plate welding structure and front and back, has four longitudinal seams, three girth joints, its total quality of such part and poor reliability.The process of known external production like product has two kinds, and is a kind of for adopting tubular electroslag remelting process, promptly smelts superstrength alloy steel pipe shape electroslag remelting spare with special equipment, the electroslag remelting pipe fitting carried out hot rolling; This kind complex process and investment are big, and China does not possess the working condition of tubular electroslag remelting process at present; Another kind is to adopt open die forgings to be processed into the product of required form after turning; Though this method is fairly simple, because the internal soundness instability of forging, all there is certain problem in aspects such as the efficient when its economy and batch process, stability.
Summary of the invention:
For overcoming the defective that exists as mentioned above, the utility model provides a kind of machine for rolling ring isolated plant of rolling asymmetric special-shaped ring, use this device can directly roll out required asymmetric special-shaped ring part, substitute intrinsic five smithwelding structures with this assembly welding structure, make the entire engine shell structure have only a girth joint, replace intrinsic seven weld seams, improved precision, reliability and the quality of stability of solid rocket motor case greatly.
For achieving the above object, the utility model adopts following technical scheme:
The machine for rolling ring isolated plant of described rolling asymmetric special-shaped ring, it adopts the method for flat-die forging, by the prefabricated special-shaped ring blank of designing requirement elder generation; Its cone-shaped roll can rotate around self axis, and can do horizontal movement, and the epicone roller can also move downward; Right-hand unit outer surface at the machine for rolling ring workbench is equipped with regulation tapering size and the king roller of takeing on neck, and king roller can rotate around the axis of self, also can be in the cross-sectional direction move left and right of its axis; Device is shaped on the mandrel of regulation appearance above the machine for rolling ring workbench, and this mandrel can rotate around self axis, also can be in the cross-sectional direction move left and right of its axis; The machine for rolling ring workbench can with the synchronous move left and right of mandrel.When starting working, the asymmetric special-shaped ring blank of prefabricated shape is installed between mandrel and the work king roller from workbench, start king roller and cone-shaped roll, make them separately around self axis rotation, simultaneously king roller is moved to the left feeding along its axis cross-sectional direction, makes cone-shaped roll along the feeding that moves right of its axis direction; Along with the carrying out of this operation of rolling, the attenuation gradually of blank cavity thickness, special-shaped ring around self axis rotation, is realized radial rolling under the effect of king roller, mandrel and cone-shaped roll; The inner flange of special-shaped ring upper end also is shaped because of the rolling effect of shoulder neck on cone-shaped roll, the king roller and mandrel.By the axial feed motion of cone-shaped roll, make the special-shaped ring blank also be rolled into the given size of designing requirement at axial direction, whole asymmetric special-shaped ring is rolled in this isolated plant to be finished.Owing to by different special-shaped ring tapering requirements designs a corresponding anti-coning angle Φ is arranged on the surface of king roller, the axial additional force in the rolling course of work and the opposite shaft orientation power of low-angle Φ generation are cancelled each other, realized the mechanical balance of the operation of rolling.
According to the special-shaped dimensional requirement of the different asymmetric special-shaped ring of required production,, just can produce the asymmetric special-shaped ring part of various different size specifications easily as long as change the physical dimension of corresponding king roller and mandrel.
Description of drawings:
Fig. 1 is asymmetric special-shaped ring machine for rolling ring isolated plant structural representation.
As shown in Figure 1: 1-machine for rolling ring mandrel, 2-machine for rolling ring king roller, 3-machine for rolling ring workbench, 4-machine for rolling ring cone-shaped roll, the asymmetric special-shaped ring of 5-.
Specific embodiment:
As shown in Figure 1: the machine for rolling ring isolated plant of this rolling asymmetric special-shaped ring, the left side in machine for rolling ring workbench (3), device has two cone-shaped rolls (4) up and down; Cone-shaped roll (4) is contained on the frame, can rotate around self axis, and can move forward and backward along horizontal direction, and the epicone roller can also move up and down, and guarantees the axially rolled of workpiece; Right-hand unit outer surface at workbench (3) is shaped on regulation tapering size and the king roller (2) of takeing on neck, and king roller (2) can rotate around self axis, also can be in the cross-sectional direction move left and right of its axis; The top device of workbench (3) is shaped on the mandrel (1) of regulation appearance, and mandrel (1) can rotate around self axis, also can be in the cross-sectional direction move left and right of its axis; Machine for rolling ring workbench (3) can with the synchronous move left and right of mandrel.During the work beginning, between the asymmetric special-shaped ring (5) of prefabricated shape, workbench (3), mandrel (1) and king roller, and asymmetric special-shaped ring (5) is close on their surface, starting king roller (2) and cone-shaped roll (4) makes them separately around self axis rotation, blank also is driven to rotate simultaneously, make simultaneously cone-shaped roll (4) along horizontal direction move forward into to; King roller is moved to the left feeding along the cross-sectional direction of its axis, and along with the carrying out of this operation of rolling, the thickness attenuation gradually of special-shaped ring (5) die cavity is until given size; Special-shaped ring (5) under the effect of king roller (2), cone-shaped roll (4) and mandrel (1) around the rotation of self axis, realize radial rolling, special-shaped ring (5) upper end inner flange also is shaped because of the rolling effect of shoulder neck on cone-shaped roll, the king roller (2) and mandrel (1).By the axial feed motion of cone-shaped roll, make special-shaped ring (5) also be rolled into the given size of designing requirement at axial direction, whole asymmetric special-shaped ring just is rolled to be finished.
Surface in king roller (2) by corresponding anti-coning angle Φ of different special-shaped ring tapering requirement design, makes the axial additional force in the operation of rolling cancel each other with the opposite shaft orientation power of low-angle Φ generation, has realized the mechanical balance of the operation of rolling.
According to the special-shaped dimensional requirement of the different asymmetric special-shaped ring of required production,, just can produce " asymmetric special-shaped ring " part of various different size specifications easily as long as change the physical dimension of corresponding king roller (2) and mandrel (1).
