BACKGROUND

[0002] (I) In terms of material surface performance: rolling technology.

[0003] Some large shaft workpieces cannot be ground in the crankshaft, and the rolling processing technology is adopted to achieve the surface roughness requirement in the drawing technical requirement, and good results are obtained. Rolling processing can produce instantaneous high temperature on the surface of the workpiece and short-term softening. The workpiece after rolling can make the metal of the wave peak after turning fill into the wave valley, make the surface produce certain plastic deformation, and then realize the change of part size and roughness. The surface roughness after rolling can reach Ra1.6μm~Ra1.8μm.

[0004] Through the rolling processing of the outer circle, cylindrical surface, conical surface and plane of the workpiece, in addition to reducing the surface roughness of the workpiece, the surface hardness of the workpiece can also be improved. In addition, sometimes the turning is difficult to repair when the tolerance is tens of microns, and the rolling processing method can be used to solve this problem. Due to these advantages, rolling processing technology has been widely used.

[0005] It is difficult to achieve ultra-high precision surface quality by using traditional processing equipment for production; some products have large structure size, which can only be turned on large vertical lathe, and the speed of large vertical lathe is low, so it is more difficult to achieve high surface quality.

[0006] In order to refine grains, reduce porosity, remove stress and improve density, electric arc additive test pieces often follow rolling after additive to improve performance. Among them, the rolling of plate type electric arc additive test pieces can be realized by using standard rolling machine tool combined with additive system, while complex surface features require corresponding special rolling equipment to meet the rolling requirements.

[0007] Prior art: a metal additive manufacturing synchronous shape cooling device, patent number: CN202211302332.6, including a mechanical arm, the end of the mechanical arm is provided with an additive manufacturing machine head, the mechanical arm is used for controlling the printing track of the additive manufacturing machine head, the outer wall of the additive manufacturing machine head is coaxially provided with a rotating device, a linear drive mechanism parallel to the axis direction of the additive manufacturing machine head is arranged on the driving end of the rotating device, and a water cooling device with a flexible cooling body is arranged on the driving end of the linear drive mechanism. The additive manufacturing synchronous shape cooling device is used by cooperating the mechanical arm with the rotating device, additive manufacturing printing and relative lagging same track rolling cooling are realized by single mechanical arm control, and then the printing efficiency and quality of the additive manufacturing device are improved.

[0008] Prior art: a rolling device for electric arc additive manufacturing, patent number: CN202310111902.1, including a base and a base platform, further comprising: a mechanical arm movably installed on the upper side of the base; a three-way rolling head movably installed at one end of the mechanical arm; a gasket arranged on the outer wall of the upper side of the base platform; a driving disc movably installed on the outer wall of the upper side of the base platform and used to drive the gasket to rotate horizontally; the base is fixedly installed on one side of the base and parallel to the base, the mechanical arm is located between the base and the three-way rolling head and fixedly connected with a control power supply, and the mechanical arm is used to drive the three-way rolling head to move on the upper side of the base platform.

[0009] Prior art: a multi-process composite electric arc additive manufacturing device and method, patent number: CN202310061152.1, the device includes an electromagnetic auxiliary electric arc additive manufacturing module, a mechanical rolling fine crystal module, an ultrasonic impact stress relief module, an electric brush surface cleaning module and a workpiece temperature control module. The method comprises the following steps: multi-process path planning and manufacturing preparation; ultrasonic impact and electric brush base plate; electromagnetic stirring pool auxiliary electric arc additive manufacturing, synchronous mechanical rolling in high temperature forging area; ultrasonic impact and electric brush current low temperature state formed pass; repeat the above steps until the workpiece is completed.

[0010] The problems existing in the prior art rolling technology are as follows: Figure 6 .

[0011] (1) The rolling force is small, the structure is complex, and the function is single, such as three-axis control rolling, mechanical arm control additive, nine-axis linkage debugging is complex and difficult.

[0012] (2) The overall structure is not convenient to disassemble, most of which are only suitable for simple hot rolling or simple cold rolling, and cannot realize separate additive or separate rolling function, only have the function of additive at the same time, and the function is less.

[0013] (3) The workpiece type is single, the processing category is single, and the internal horizontal and vertical diagonal ribs and other structures of large size workpieces cannot realize rolling process.

[0014] (ii) in the aspect of material forming: roll bending process.

[0015] The purposes of the roll bending of the profile now mainly include two aspects, the first aspect is to roll the straight plate into a roll bending profile with a predetermined radius of curvature, and the second aspect is to restore the old plate that does not meet the specifications in the process to a straight material.

[0016] The existing problems of the roll bending process are as follows.

[0017] (1) For the roll bending process, most of the simple roll pressing equipment adopts four-axis or three-axis roller structure, and the multi-roll process is not clear.

[0018] (2) It mainly relies on manual experience to assist in processing, and repeatedly bends, which has a certain degree of influence on the material properties.

[0019] In summary, for the combination of roll bending and roll pressing, there is no additive and roll bending and roll pressing integrated equipment at present. The separate roll pressing, additive, and roll bending equipment requires a large amount of manpower and material resources to maintain, and the time cost required for the hoisting and transfer of large-size products in each device is extremely large, and there are certain safety problems. Moreover, the scattered arrangement also requires a large amount of space and transfer storage space, which is a huge cost. For a spacecraft storage tank and other workpieces, once the additive roll pressing is completed, the shell plate will produce irregular deformation, and even the bus will be deformed, which can only be faced with overall scrap, or manual finishing, or returned to the roll bending machine for finishing. The roll bending may cause deformation of the internal rib, and the process of repeated transfer and hoisting is time-consuming and labor-intensive. SUMMARY

The hydraulic cylinder support plate 31 and the fulcrum support plate 32 can be omitted, that is, the sliding platform 2 can be directly connected with the hydraulic cylinder 4 and the fulcrum support rod 5.

[0050] A certain number of support plate transposition reserved hole positions (not shown in the figure) and replacement bearing positions 7 are arranged on the upper part of the sliding platform 2. By changing the positions of the hydraulic cylinder support plate 31 and the fulcrum support plate 32 and the positions of the hydraulic cylinder 4 and the fulcrum, the lengths of the power rod 43 and the force receiving rod 44 can be changed, that is, the machining depth can be changed, and the balance between power and machining depth can be realized.

[0051] The end of the force receiving rod 44 is provided with a tool disc mounting position 6 and a mechanical mounting position 8.
