The utility model is provided with a lifting plate, a convex block, a turntable, a threaded column, a rotating handle, a loading plate, a measuring line, a fixed The invention relates to a bicycle frame having a plurality of plates, a pressing plate, an extrusion block, a tension spring, a tooth plate, a gear, a rotating column and a handle, which solves the problem of the steel pipes required for the frame of the bicycle. Generally, holes are punched in the steel pipes by an electric drill. When a person uses an electric drill to drill holes in the steel pipes, the steel pipes are easy to roll, which makes it inconvenient for the person to determine the drilling position. At the same time, the person's hand is easy to touch the drill bit on the electric drill, which can easily cause injuries to the person.

[0024] The frame tube punching device disclosed in this embodiment determines whether it is necessary to rotate the direction of the first support plate 221 and the second support plate 24 according to the shape of the frame tube 8 to be punched before use. When the end surface shape of the frame tube 8 to be punched is rectangular, the direction of the second rectangular groove 245 above the second support plate 24 is adjusted to a direction perpendicular to the first push plate 31, and the connecting shaft 243 is used to fix it. Then, the angles of the first support plate 221 and the pressing plate 23 are adjusted so that the first rectangular groove 232 is parallel to the second rectangular groove 245. After the adjustment is completed, the frame tube 8 to be punched is placed between the second support plate 24 and the support groove 311, so that the two ends of the frame tube 8 are respectively located at On the inner side of the support groove 311 and the second rectangular groove 245, the servo motor 35 is started by the control box 7, and the first push plate 31 and the frame tube 8 are pushed to the other end of the second rectangular groove 245 by driving the rotation of the screw rod 32 and then stopped after a certain distance, and the punching machine 22 is started to move the punch downward to punch the frame tube 8. During the punching process, the punch drives the first support plate 221 to press the spring 222 and the elastic column 223 downward, so that the spring 222 and the elastic column 223 are deformed, so that the punch continues to move downward after the first rectangular groove 232 at the lower end of the pressing plate 23 contacts the frame tube 8. After the punching operation is completed, the punch is in the spring 222 and the elastic column 223. Under the effect of rebound, the pressing plate 23 moves upward to separate from the second supporting plate 24 and the frame tube 8, and then the servo motor 35 is started again, and after pushing the frame tube 8 forward a certain distance, it is turned off, and the punching machine 22 is used again to punch the frame tube 8, and the storage plate 53 provides support for the frame tube 8 in the direction of the frame tube 8 extending out of the second supporting plate 24. After the punching is completed, the control box 7 is used to control the first telescopic rod 44 and the electric clamp 45 to operate, so that the electric clamp 45 moves in the direction of the frame tube 8 to clamp the frame tube 8, and then the slider 43 is controlled to move in the direction away from the second supporting plate 24. After the frame tube 8 is separated from the second supporting plate 24, the baffle 54 is adjusted. The position in the slide groove 531 makes the distance between the baffle plate 54 and the end of the frame tube 8 slightly larger than the length of the frame tube 8, adjust the position of the clamping block 55 to fix the baffle plate 54, release the electric clamp 45, shrink the first telescopic rod 44, move the electric clamp 45 to the upper end of the frame tube 8, use the control box 7 to start the extension of the second telescopic rod 51, drive the second push plate 52 to move in the direction of the frame tube 8, push the frame tube 8 from above the storage plate 53 to the collection basket 6, then reset the servo motor 35, place another frame tube 8 to be punched between the support groove 311 and the second support plate 24, repeat the above operation, and the punching operation of the frame tube can be realized.

[0025] When the end face shape of the frame tube 8 to be punched is circular, the directions of the first semi-annular groove 233 and the second semi-annular groove 246 are adjusted to be perpendicular to the first push plate 31, and then the above operation is repeated to complete the punching operation of the frame tube. In actual use, the clamping mechanism and the pushing mechanism 5 can also be moved away from one end of the first workbench 1, and the frame tube 8 can be manually placed in the second rectangular groove 245 or the second semi-annular groove 246, so as to perform punching operations on the frame tube after bending and forming, thereby enriching the application scope of the device and improving the utilization rate of the device.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
