Wherein, the inner wall of the profiling block 13 is respectively provided with an oil control groove, the oil control groove is movably provided with an oil control ball 12, the upper end and the lower end of the oil control groove on the profiling block 13 are respectively fixedly provided with a retainer ring 120 for limiting the oil control ball 12, in order to achieve the purpose of preventing the generation of an air cavity, the oil control ball 12 is arranged on the profiling block 13, and the retainer rings 120 are arranged at the upper end and the lower end of the oil control groove on the profiling block 13, so that when the wire drawing oil is continuously introduced into the oil storage cavity 80, the oil control ball 12 is contacted with the retainer ring 120 at the lower side, the oil control ball 12 is sealed with the retainer ring 120 at the lower side, the phenomenon that the wire drawing oil in the oil storage cavity 80 leaks is avoided, meanwhile, when the profiling block 13 extrudes the wire drawing belt 7 through the oil control ball 12, the oil control ball 12 is extruded with the retainer ring 120 at the upper side, and the wire drawing belt 7 rotates through extrusion in the process of movement, therefore, the wire drawing oil in the oil storage cavity 80 slides out, meanwhile, the phenomenon of local high temperature caused by continuous sliding friction between the wire drawing belt 7 and the profiling block 13 is avoided through the rolling contact between the oil control ball 12 and the wire drawing belt 7, meanwhile, the wire drawing belt 7 is extruded on a curved part through the wire drawing oil medium in the oil storage cavity 80 through the oil control ball 12, so that the wire drawing belt 7 can be continuously attached to the surface of the curved part through the extrusion of the oil control ball 12, and therefore, in the process of friction between the wire drawing belt 7 and the part, the air cavity generated on the wire drawing belt 7 can be discharged, the wire drawing belt 7 can be always attached to the surface of the curved part for processing, and the purpose of preventing the generation of the air cavity is finally achieved.
The side wall of the oil control ball 12 is provided with a ball groove for discharging the wire drawing oil in the oil storage cavity 80, and in order to achieve the purpose of wetting the wire drawing belt 7 in time, the side wall of the oil control ball 12 is provided with the ball groove, so when the wire drawing belt 7 drives the oil control ball 12 to rotate, the amount of the wire drawing oil flowing out in single rotation can be increased through the ball groove on the surface of the wire drawing belt 7, meanwhile, the wire drawing belt 7 is always attached to the oil control ball 12, when the wire drawing oil in the oil control ball 12 flows out, the wire drawing oil can directly act on the wire drawing belt 7, so that the wire drawing oil always exists on the wire drawing belt 7, and finally the purpose of wetting the wire drawing belt 7 in time is achieved.
The wire drawing belt 7 is made of wear-resistant cloth with a certain tensile strength and oil conveying holes in the inner wall, the wire drawing oil on the wire drawing belt 7 is easier to act on the contact surface of the wire drawing belt 7 and the curved surface part, so that the oil conveying holes are formed in the wire drawing belt 7, and the wire drawing oil is continuously rotated through the wire drawing belt 7 when flowing to the oil conveying holes in the wire drawing belt 7 through the oil control balls 12, so that the wire drawing oil is thrown out to the contact surface of the wire drawing belt 7 and the curved surface part under the action of centrifugal force.
The end area value of the oil storage tank 8 is 10-13 times of the end area value of the tightening rubber 100, in order to enable the tightening rod 10 to timely push the driven wheel 6 to tighten the wire drawing belt 7, the end area value of the tightening rubber 100 is smaller than the end area value of the oil storage tank 8, therefore, in the working process, the medium pressure in the oil storage chamber 80 is the same at all positions, when the end area of the oil storage tank 8 is large, the stress is faster relative to the tightening rubber 100, the medium in the oil storage chamber 80 can continuously push out the profiling block 13 to pressurize the tightening rubber 100 again, when the curvature of the curved surface part changes, the profiling block 13 can be firstly attached, and the driven wheel 6 can timely adjust the tightness of the wire drawing belt 7 along with the extension amount of the profiling block 13.
Wherein, the end face diameter value of the oil control ball 12 is 2-4 times of the diameter value of the oil delivery hole on the wire drawing belt 7, in order to prevent the oil control ball 12 from being blocked to the oil delivery hole on the oil control ball 12 when the oil delivery hole on the wire drawing belt 7 is contacted with the oil control ball 12, the end face diameter value of the oil control ball 12 is larger than the end face diameter value of the oil delivery hole on the wire drawing belt 7, which is not only convenient for the wire drawing oil to flow to the oil delivery hole on the wire drawing belt 7, but also prevents the phenomenon that the movement resistance of the wire drawing belt 7 is increased because the oil control ball 12 is blocked to the oil delivery hole.
Meanwhile, in the application, in order to prevent the driving wheel 5 from being pushed out of the driven wheel 6 due to the rotational tension of the driving wheel 5 in the rotating process, in the working process of the driven wheel 6, the extrusion pressure on the tightening rubber 100 in the oil storage chamber 80 is always greater than the tension on the driven wheel 6 due to the wire drawing belt 7 of the driving wheel 5 in the working process, so that the phenomenon that the driven wheel 6 is continuously displaced left and right in the working process due to the tension of the wire drawing belt 7 in the continuous rotating process of the driving wheel 5 is avoided.
The using method and the working principle of the invention are as follows: firstly, a curved surface part is fixedly placed on a lifting platform 2, the lifting platform 2 is lifted to a proper position through a lifting switch 3, secondly, the wire drawing oil is continuously connected into an oil inlet 9, meanwhile, a driving motor drives a driving wheel 5 to rotate (the driving motor is not shown in the figure) through a driving switch 4, further, a wire drawing belt 7 is synchronously rotated through the rotation of the driving wheel 5, the wire drawing oil continuously flows into an oil storage cavity 80 from the oil inlet 9, so that the profiling block 13 continuously causes the profiling block 13 to protrude outwards due to a medium in the oil storage cavity 80 and extrudes the wire drawing belt 7 to the curved surface part through an oil control ball 12 on the profiling block 13, and then, the profiling block 13 is completely attached to the surface of the curved surface part due to the continuous filling of the medium in the oil storage cavity 80, and simultaneously, the tightening rubber 100 in the oil storage cavity 80 pushes a tightening rod 10 to move outwards, and then the tension rod 10 pulls the driven wheel 6 to slide on the relaxation groove 11, so that the wire drawing belt 7 is tensioned by the driven wheel 6, and then the rotation is more convenient, then the wire drawing belt 7 is attached to the curved surface part by the profiling block 13, and then the oil control ball 12 is attached to the upper part of the retainer ring 120 by the wire drawing belt 7 (shown in figure 3), then after the wire drawing belt 7 rotates, the oil control ball 12 is driven to rotate synchronously, so that the wire drawing oil in the oil storage cavity 80 continuously slides out through the ball groove arranged on the oil control ball 12 and then flows to the oil conveying hole on the surface of the wire drawing belt 7, and simultaneously the wire drawing oil in the oil conveying hole slides to the contact part of the curved surface part and the wire drawing belt 7 under the influence of the centrifugal force by the continuous rotation of the wire drawing belt 7, and then after the processing is finished, part of the wire drawing oil in the oil storage cavity 80 is pumped out from the oil inlet 9, and the copying block 13 is self-restored to the original position;
when the plane part is processed, the surface of the plane part can still be subjected to wire drawing and polishing according to the operation.
