Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe punching machines, and in particular to a guide mechanism of a steel pipe punching machine. Background Art

[0002] The steel pipe piercing machine is a device specially used for piercing steel pipes. Its working principle is mainly to heat the surface of the steel pipe through electric spark discharge, so that it reaches the melting point and drills through, thereby completing the piercing operation; seamless steel pipe is made by piercing a whole round steel, and there is no weld on the surface of the steel pipe. In the production of seamless steel pipes, the role of the piercing process is to pierce the tube blank into a hollow steel pipe. If there are some defects on the steel pipe, it is difficult to eliminate or reduce them through subsequent processes. Therefore, it plays an important role in the piercing process in modern steel pipe production.

[0003] In the prior art, for example, Chinese patent CN213224396U discloses a punching machine for steel pipe processing, which includes a workbench, a support frame, a drilling device, a fixing device and a controller. A groove is provided at the upper position of the workbench, a screw is provided at the inner cavity of the groove, a rotating handle is installed at the right end of the screw, a threaded sleeve is engaged and transmitted at the outer wall of the screw, a storage box is fixedly connected to the top position of the threaded sleeve through a connecting rod, a bracket is installed at the upper position of the inner cavity of the storage box, and a rotating wheel is rotatably connected to the top position of the bracket.

[0004] When drilling holes in steel pipes, existing punching machines usually use a clamping device to clamp the steel pipe, and then use a guide structure to push the steel pipe, and the drill bit drills the steel pipe. However, when the steel pipe is punched, only one end of the steel pipe is clamped, and the guide structure cannot effectively fix the steel pipe, resulting in the steel pipe being prone to shaking and instability during the punching process. At the same time, the steel pipe is in a clamped state during the pushing process, resulting in the drill bit being able to drill the steel pipe in only one direction during one processing process of the drilling machine. After the steel pipe is drilled in one direction, the direction cannot be quickly adjusted.

[0005] Therefore, improvements are made to address the above problems. Utility Model Content

[0033] A driving motor 4 and an adjusting and pushing assembly 6, wherein the driving motor 4 is arranged on a side surface of the base 1, and the adjusting and pushing assembly 6 is arranged inside the base 1;

[0034] The clamping assembly 5 includes a pair of telescopic cylinders 5-1, which are fixed on both sides of the top frame 2. The output ends of the pair of telescopic cylinders 5-1 are connected to the cross frame 5-2. Several sleeve frames 5-3 are set at the bottom of the cross frame 5-2. The surface of the sleeve frame 5-3 is provided with a side opening 5-4. The side opening 5-4 is rotatably connected to a rotating wheel 5-5. The surface of the rotating wheel 5-5 is an arc-shaped concave structural surface.

[0035] In this embodiment, in order to achieve the effect of stably clamping the entire steel pipe, a clamping assembly 5 is designed. Two telescopic cylinders 5-1 are provided on both sides of the top frame 2. The output end of the telescopic cylinder 5-1 is connected to a cross frame 5-2. The cross frame 5-2 is located at the long mouth 3. A plurality of sleeve frames 5-3 are provided at the bottom of the cross frame 5-2. The surface of the sleeve frame 5-3 is provided with a side opening 5-4 and is connected to a rotating wheel 5-5 for rotation inside.

[0036] Furthermore, the adjustment pushing assembly 6 includes a long slot 6-1, which is opened on the surface of the base 1, and a pair of round rods 6-2 are arranged in the long slot 6-1. The round rods 6-2 are slidably sleeved and connected to a movable frame 6-3. A driving screw 6-4 is rotatably connected in the long slot 6-1, and the driving screw 6-4 is connected to the output end of the driving motor 4. The driving screw 6-4 is connected to the movable frame 6-3 by threaded cooperation. A second motor 6-5 is provided on the side surface of the movable frame 6-3, and a rotating seat 6-6 is provided at the output end of the second motor 6-5.
