Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a shaft guide tube punching processing device. Background Art

[0002] In the existing punching processing technology for shaft guide tubes, a punch is often used to directly punch the workpiece confined on the die core. The part of the workpiece to be punched will be processed out by the punch through extrusion. Compared with drilling, punching is faster and more convenient, and the punching size is fixed, which reduces processing errors.

[0003] After the shaft guide tube is punched, it can more conveniently allow hydraulic transmission pipelines, wires, etc. to pass smoothly, and it can also effectively reduce the resistance encountered by the fluid when flowing in the pipeline. However, it should be noted that when punching the workpiece, raised burrs are often produced on the back of the workpiece. The presence of these burrs may scratch the transmission pipeline, causing it to be damaged, and may also hinder the normal movement of the fluid and affect its smoothness. In view of this, an additional process specifically for trimming burrs is required in the future. This will inevitably increase the cost of manpower, and also reduce the overall production efficiency to a certain extent, so that the production progress is adversely affected to a certain extent.

[0030] Working principle: Please refer to Figure 1-Figure 6As shown, the unprocessed shaft guide tube is placed in the gap between the mold core 8 and the limiting block 9. When the workpiece is placed in a suitable position, the top of the U-shaped movable plate 701 will press against the bottom of the workpiece, and the hydraulic cylinder 1001 will be started. The hydraulic cylinders 1001 on both sides will push the movable plate 1002 to move in the direction of the limiting block 9. Synchronously, the two punches 1003 fixed on the movable plate 1002 will also be pushed into the inside of the limiting block 9 and squeeze the thin wall of the shaft guide tube that needs to be processed. With continuous squeezing, the punches 1003 will pass through the through hole 803 and punch out a plurality of circular holes on the thin wall of the shaft guide tube.

When the clamping devices on both sides clamp and fix the mold core 8, the first cylinders 6 on both sides will shrink the cylinders synchronously, which will drive the gear sliding mechanism 7 to move toward the edge of the bottom plate 1, thereby guiding The shaft guide tube will lose the support of the U-shaped movable plate 701 and will fall from the discharge port 2 to the outside of the machine, thereby reducing the steps of removing the workpiece. After the workpiece is moved out, the first cylinders 6 on both sides will extend the cylinders, so that the gear sliding mechanism 7 moves closer to the center of the bottom plate 1, so that the bevel gear sets will mesh with each other again, and at the same time, the upper end of the U-shaped movable plate 701 will also be inserted into the limit ring 805. At this time, the second cylinder 1101 will contract, and the clamping mechanism 11 will release the mold core 8 and put the unprocessed shaft guide tube in again, and the cycle will be repeated.
