Working principle:
The cold rolling machine tool adopts a vertical layout, two frames 11 are vertically arranged on a base 1, a rolling wheel shaft assembly 2, a mandrel assembly 3 and a supporting wheel assembly 5 are arranged on the frames 11 from bottom to top, a feeding mechanism mainly composed of a feeding slideway 61 is arranged on one side of each frame 11, and a discharging mechanism mainly composed of a discharging slideway 62 is arranged on the other side of each frame 11. The workpiece 8 to be processed is vertically placed in the feeding slide 61, the workpiece 8 slides down along the feeding slide 61 to the bottom of the feeding slide 61, the horizontal pushing cylinder 64 pushes the workpiece 8 into the claw 63, and the pushing cylinder 65 pushes the workpiece 8 into the processing area between the two frames 11. After the workpiece 8 is in place, the mandrel assembly 3 adjusts the vertical height by utilizing the vertical guide rail 31, the oil cylinder 33 is started, the piston rod 33a extends out, and the mandrel 34 is sent into an inner hole of the workpiece 8; the master cylinder 51 of the support wheel assembly 5 is then operated to lower the master slide 52 with the support wheel 53 and bring the support wheel 53 into supporting contact with the spindle 34. As shown in fig. 15, during cold rolling, the supporting wheel 53 provides a pressing force, the rolling wheel 22 is driven by the gear motor 21 to rotate clockwise, the rolling wheel 22 (as an outer die, the outer circumferential surface of the rolling wheel 22 has a workpiece contour shaped groove) contacts the outer surface of the workpiece 8, the mandrel 34 (as an inner die, the outer circumferential surface of the mandrel 34 also has a workpiece contour shaped groove) contacts the inner surface of the workpiece 8, the mandrel 34 performs a counterclockwise driven rotation movement, the mandrel 34 continuously leans against the rolling wheel 22 under the pushing of the supporting wheel 53, so that the wall thickness and the diameter of the workpiece 8 are reduced, the groove shape is mapped on the workpiece 8, and the workpiece 8 is subjected to cold rolling; the workpiece 8 after the cold rolling is finished being blanked from the blanking slide 62 (the workpiece 8 to be next processed is pushed into the processing area while the workpiece finished in the processing area is pushed into the blanking slide 62). The feeding and discharging of the workpiece 8 is automatically completed by the feeding and discharging mechanism, and the automation degree is high. The cold rolling machine tool adopts a vertical structure, utilizes a vertical space, greatly reduces the occupied area of equipment, and can be suitable for processing workpieces with the outer diameters of 250mm-400 mm.
The cold rolling machine tool is provided with the roundness roller assembly 4, and the roller 44 of the roundness roller assembly 4 always keeps applying proper correction force to the workpiece 8 under the control of the servo motor 41, the rolling guide rail 42 and the ball screw 43 so as to ensure the roundness precision of the workpiece. If the correction force is too small, the effect of repairing the round is not good, and if the correction force is too large, the rolling force energy parameter is deteriorated, so that the position of the workpiece is accurately controlled by a pre-programmed program along with the increase of the size of the workpiece.
The main slide block 52 of the supporting wheel assembly 5 is guided by the slide block guide rail 54, and the supporting wheel 53 is driven to press the mandrel 34 under the pushing of the main oil cylinder 51, and then the mandrel 34 presses the workpiece 8, so that the rolling and expanding processing is completed. The rolling force is very large and is 500-1500KN, and the feeding speed is required to be changed in a very large range (0.01-20 mm/s), so as to adapt to the requirements of different stages of fast forward, rough rolling, fine rolling and the like. Wherein the fast forward and fast backward actions are supplied by a hydraulic pump, and the rolling stage is supplied by a high-pressure small-flow pump driven by a servo motor.
The cold rolling machine tool is also provided with a measuring mechanism 7, the size of a workpiece can be measured through a grating ruler 74 on the measuring mechanism 7 and fed back to an electric control system, and the electric control system timely adjusts feeding parameters according to the change of the size until the rolling process is completed.
While the preferred embodiments of the present invention have been illustrated, various changes and modifications can be made by one of ordinary skill in the art without departing from the scope of the invention.
