Please refer to Figures 1, 2 and 3 for a preferred embodiment of the metal bar sizing machine of the present invention, but the embodiments are for illustrative purposes only and are not limited by the structure in the patent application; The metal bar fine boring machine A comprises the following structure: a base 10 comprising a bottom portion 11 for placement and a processing table 12, wherein the processing table 12 is provided with a transversely extending linear guide. The movable rail 13; the lower squeezing die 20 is disposed on the guiding track 13, and the lower squeezing die 20 is laterally reciprocatingly displaced along the guiding track 13, and wherein the top surface of the lower squeezing die 20 The set position has a plurality of limiting pieces 21 arranged in parallel, and each of the limiting pieces 21 forms a bar-shaped limiting groove 22 opposite to the concave shape for placing the metal bar 30 to be processed therein; At least one reciprocating driving device 40 is disposed on the processing table 12 of the base 10 and coupled with the lower jaw 20 to drive the lower reciprocating mold 20 to generate a lateral reciprocating displacement motion by the reciprocating driving device 40. a lifting upper seat 50, which is disposed on the base 10 by a plurality of lifting columns 60 Upper surface 12, and enabling the system 50 may be located in the upper seat lift die orientation rubbing surface 20 An upper die 70 is disposed at the bottom of the liftable upper seat 50. The bottom surface of the upper die 70 is provided with a flat pressing surface 71 and a limiting piece 21 and a rod provided on the top surface of the lower jaw 20 The material limiting groove 22 is vertically opposed to the top side of the metal bar 30 to be processed; and the upper pressing die 70 is driven by a pressure device 80. Pressing to generate a pressing force on the metal bar 30.

With the above structural composition and technical features, the practical use of the metal bar fine boring machine A disclosed in the present invention is mainly for surface precision processing of the metal bar 30, and the operation mode is a squatting squatting mode. 20 is displaced to a position which is offset from the upper die 70 and is exposed (as shown in FIG. 3), and then the metal bar 30 to be processed is placed on the top surface of the lower jaw 20 The bar limiting groove 22 formed between the bit pieces 21 is then driven by the reciprocating driving device 40 to displace the lower jaw 20 to a position corresponding to the lower portion of the upper die 70 (as shown by L1 in FIG. 4). And then, by lowering the liftable upper seat 50, the flat pressing surface 71 provided on the bottom surface of the upper stamper 70 is driven downward against the top side of the metal bar 30 to be processed (as shown in FIG. 5, L2). As shown, the surface processing of the metal bar 30 can be performed. The processing method of the present invention is to use the reciprocating driving device 40 to drive the lower squeezing die 20 to generate a lateral reciprocating displacement motion during which the top side of each metal bar 30 is flattened by the bottom surface of the upper die 70. The surface 71 is pressed, wherein the pressure device 80 is pressed down by a set value (for example, 1 μm in one feed), and the bottom sides of each metal bar 30 are again restricted to the adjacent limit piece 21 In the bar limit groove 22 formed therebetween, each of the metal bars 30 faces the flat pressing surface 71 of the lower jaw die 20 and the upper die 70 in the case where both the up-and-down direction and the lateral position are restricted. The mutual misalignment between the front and the rear drives the metal bars 30 to produce an interactive movement of the forward and reverse rotations in the bar limit groove 22 (please refer to L3 and L4 in Figures 6 and 7). a reciprocating displacement within a radial distance that produces a small and stable roll shaping effect on the surface of the rotating metal bar 30 during the movement, constituting a unique processing form of the side edge rim, thus continuing One section of processing After the time, the processing of the metal bars 30 can be achieved. The purpose of the press roll forming is to perform a relatively precise refining process on the outer diameter of the metal bar 30 (very similar to a hand roll) The principle of the dough, and its greatest advantage is that the processing of the majority of the metal rods 30 can be carried out at the same time, which is by no means comparable to the conventional bar processing methods.

As shown in FIG. 2, the top surface of the lower jaw 20 can be formed with a plurality of mounting recesses 23 arranged in parallel, and each of the mounting recesses 23 is provided with a screw hole 24 at both ends thereof. Each of the limiting pieces 21 is correspondingly embedded in each of the mounting recesses 23, and each of the limiting strips 21 is provided with a through hole 25 at opposite ends thereof to be opposite to the screw holes 24 provided at the two ends of the mounting recess 23. The position of the limit piece 21 is achieved by the bolts 26 being threaded through the set of screws.
