In addition, the application also provides a method for rolling the workpiece 33 by using the reciprocating rolling device 100. The method comprises the following steps: a pair of roller blades in the roller blade set 21 of the rolling mechanism 2 are reciprocated to roll the workpiece 33 reciprocally.
In the method for rolling the workpiece 33, on one hand, only two roller cutters are adopted, so that the generation of heat on the workpiece 33 can be effectively reduced in the process of hard and rapid contact between the roller cutters and the workpiece 33, the phenomenon of stress concentration is effectively avoided, and the structural strength of the workpiece 33 is further protected; on the other hand, the workpiece 33 is rolled respectively in the forward direction and the backward direction of the same straight line by the two roller cutters, so that burrs and marks on the surface of the workpiece caused by larger impact force generated on the workpiece in the same direction by the roller cutters in the prior art are effectively avoided, the surface of the workpiece 33 repeatedly rolled by the pair of roller cutters is smoother, and further secondary processing on the workpiece is effectively avoided.
In a preferred embodiment, in an initial state in which the roller blade set 21 reciprocates, the workpiece 33 is located in an area between a pair of roller blades, and during completion of one rolling cycle of the roller blade set 21, one roller blade in the roller blade set 21 reciprocates first the entire rolling width of the workpiece, and then the other roller blade in the roller blade set 21 reciprocates again the entire rolling width of the workpiece. With this arrangement, one of the roller blades in the roller blade group 21 can be reciprocated first to punch the notch into the workpiece 33, and in this process, the reciprocation of the roller blade can realize the deburring function for the notch, and then the reciprocation of the other roller blade can roll the notch again, which helps to improve the quality of the rolled notch while further avoiding the generation of burrs.
In another preferred embodiment, in an initial state in which the roller blade group 21 reciprocates, the workpiece 33 is located in an area between a pair of roller blades, and during completion of one rolling cycle of the roller blade group 21, one roller blade of the roller blade group 21 rolls the entire rolling width of the workpiece 33 in the forward direction when the roller blade group 21 moves in the forward direction, and rolls the entire rolling width of the workpiece 33 in the reverse direction when the roller blade group 21 moves in the reverse direction, and the other roller blade rolls half or more of the rolling width of the workpiece 33 in the reverse direction. With this arrangement, one of the roller blades in the roller blade group 21 can positively punch the notch into the workpiece 33, and the other roller blade reversely presses the notch back, so that the generation of burrs can be effectively avoided. The roller blade of the reverse back-pressing notch can effectively shorten the period of one-time reciprocating movement of the roller blade set 21 only by half or more than half of the rolling width of the workpiece 33, thereby being beneficial to improving rolling efficiency.
It should be noted that the above-mentioned "rolling width" is to be understood as the width of the entire notch rolled out by the roller blade set during completion of one rolling cycle, and the width of the notch is to be understood as the length of the notch on the workpiece 33 in the left-right direction as shown in fig. 3.
The method of rolling the workpiece 33 according to the present application further comprises: after the roller blade set 21 of the rolling mechanism 2 completes one rolling cycle, the second driving device 23 controls the roller blade set 21 to move towards the workpiece 33 so as to adjust the rolling depth. Preferably, the displacement of the movement of the control roller blade set 21 towards the workpiece 33 ranges between 0.01mm and 0.03mm, preferably 0.02mm. Because the rolling depth of each adjustment is smaller, namely the feeding amount of the roller cutter is smaller, the phenomenon of slotter of the notch can be effectively avoided, namely the notch of the workpiece 33 is communicated with the inner cavity of the workpiece 33 due to the overlarge feeding amount.
It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs.
In the description of the present application, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or number of technical features indicated. In the description of the present application, the meaning of "plurality" is two or more unless specifically defined otherwise.
