The present invention relates to a processing seat processing apparatus of the axle beam pipe, and more particularly, to a processing seat processing apparatus of the axle beam pipe, the processing of the processing seat surface on each side of both ends in the manufacturing process of the axle beam pipe. By processing both sides by one press from inside to outside, the number of processes can be significantly reduced, and the processing seat surface processing of the axle beam pipe that can significantly reduce the manufacturing cost since no expensive dedicated cutting device is required. Relates to a device.

Typically, the axle beam (3) mounted to the vehicle serves to support the shock absorber, coil spring and torsion bar of the rear chassis frame of the vehicle, the general form of the axle beam is shown well in FIG. Looking at the form through the manufacturing process, first, the axle beam pipe is cut to fit the axle, and then the axle beam pipe is formed into the required shape, and then the pipe processing seat 4 is processed to manufacture the axle beam pipe. To complete.

In order to process the pipe processing seat surface of the axle beam processing process, various methods have been attempted. The most basic form is a punching method using a press die, which is performed through two punching processes. The upper end of the pipe cutting seat of the axle beam pipe is machined into a semicircle with two press mold punches, the axle beam pipe is turned upside down, and the bottom of the pipe machining seat of the axle beam pipe is cut twice in the second punching process. As a press mold punch, it is processed into a semicircle shape.

The prior art method of punching the pipe processing seat of the axle beam pipe by the press mold has a disadvantage of performing a total of four mold punchings, which requires a great deal of processing time, as well as internally during the press mold. The furnace punching had various problems such as the deformation of the arm pipe due to the increase in the number of punchings due to impossibility.

In order to solve this problem, a device for rotating cutting the semi-circular shape at the same time by a shell cutter of a shell cutting method has been developed and used, but this also has a disadvantage of requiring a lot of cutting time. In order to cut into the shell shape, as well as a lot of other necessary equipment, as well as the price of the cutting device itself is very expensive, it has a problem that acts as a price increase factor of the trailing arm produced.

Accordingly, the present invention has been made in view of the above-described problems, and after the notch punch coupled with the cam slide is rapidly advanced to the lowering of the first cam stroke plate inside both ends of the axle beam pipe, the second cam stroke plate By lowering the cam slide on both sides, the notch punch is punched from the inside of the axle beam pipe to the outside, thereby significantly reducing the number of machining steps on the machining seat and allowing the machining seat to be machined within a short time.

In addition, as it is processed in the form of a press, the additional devices required for it are simplified to significantly reduce the price per unit of processing equipment, and to reduce the manufacturing cost of the axle beam pipe manufactured accordingly for another purpose. do.

The present invention relates to a processing seat processing apparatus of the axle beam pipe, the process number by processing the machining seat surface on each side of both ends in the manufacturing process of the axle beam pipe by only one press working from the inside to the outside during processing, In addition to significantly reducing the cost, there is a feature that can significantly reduce the manufacturing cost because no expensive dedicated cutting device is required.

The present invention is largely composed of four parts, is installed on the base (1) is configured to move forward and backward along the guide rail 14, the notch die 11 is formed on both sides to expand or contract both sides It is configured to be, a notch punch 12 is formed on the front side, the rear side is formed on the cam slider 10 and the upper plate 2, the cylinder 13 is formed, the upper surface of the cam slider 10 The reverse triangular membrane so as to conform to the first cam stroke plate 20 formed to advance the cam slider 10 horizontally by descending vertically along the inclined surface formed at the rear, and the V-shaped groove formed on the upper surface of the cam slider 10. A second cam stroke plate 30 formed on the upper plate 2 in a large shape and formed to extend the cam slider 10 in both side horizontal directions by descending vertically along the v-groove, and the bottom of the upper plate 2. In the notch punch (1 The upper punch guide 41 of the form corresponding to the upper middle part of 2) is formed, the lower punch guide 42 of the form corresponding to the middle lower part of the notch punch 12 is formed in the upper part of the base 1, respectively.
