DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4 A cutting device for galvanized pipe processing, including workbench 1, feeding assembly, pressing assembly and cutting assembly, the workbench 1 below four corners are provided with supporting leg 2, the feeding assembly includes motor 3, screw rod 4, sliding block 5, feeding plate 6 and connecting piece, the workbench 1 top one end is provided with chute, the chute is provided with screw rod 4 and sliding block 5, the sliding block 5 is connected with screw rod 4 by screw thread, the sliding block 5 is provided with mounting groove, the feeding plate 6 below is connected with the mounting groove through connecting piece, the motor 3 output passes through the workbench 1 and is connected with screw rod 4, the cutting assembly includes the supporting frame 7 that is open at the bottom, first lifter 8, mounting seat 9 and cutter 10, the workbench 1 top other end is provided with supporting frame 7, the first lifter 8 passes through the top wall of supporting frame 7 and is connected with mounting seat 9, the mounting seat 9 is provided with cutter 10 near one end of feeding assembly, the supporting frame 7 top wall below is also provided with pressing assembly, the workbench 1 is also provided with roller frame 11, the roller frame 11 is also provided with supporting roller 12, the supporting roller 12 is arranged below the output end of pressing assembly, the supporting roller 12 is provided with rounded corner.

[0024] The corresponding feeding plate 6 is provided with a groove matched with the outer wall of the galvanized pipe of the corresponding specification. The pipe is inserted into the groove. The feeding plate 6 is connected with the sliding block 5 through the connecting piece. The bottom wall of the pipe contacts the supporting roller 12. At this time, the first lifter 8 is in the retracted state. After the motor 3 (a servo motor is adopted) is started, the output end drives the screw 4 to rotate in the sliding groove at one end above the workbench 1. Since the sliding block 5 is threadedly connected with the screw 4, according to the screw transmission principle, the sliding block 5 will accurately move in the sliding groove along the axial direction of the screw 4. The feeding plate 6 is connected with the mounting groove on the sliding block 5 through the connecting piece. Therefore, the feeding plate 6 will move synchronously with the sliding block 5, so as to realize the stable feeding of the galvanized pipe. The servo motor 3 can accurately control the rotating speed and direction according to the cutting requirement, and then accurately control the feeding speed and direction of the feeding plate 6. After the material is fed to the corresponding position, the material is clamped by the pressing assembly. After the first lifter 8 (a hydraulic cylinder is adopted) is started, the output device drives the mounting seat 9 to lift. The cutter 10 on the mounting seat 9 also lifts. According to the pipe diameter of the galvanized pipe and the cutting requirement, the first lifter 8 is adjusted to make the cutter 10 reach the appropriate height. In the cutting process, the cutter 10 cuts the galvanized pipe which is stably fed by the feeding assembly and fixed by the pressing assembly. Since the height of the cutter 10 can be flexibly adjusted, the accuracy and quality of cutting can be ensured, and the inclination of the end of the galvanized pipe can be avoided. The supporting frame 7 provides a stable support structure for the cutter 10.

[0025] In actual use, the pressing assembly includes a second lifter 13 and a pressing plate 14. The output end of the second lifter 13 penetrates through the top wall of the supporting frame 7 and is connected with the pressing plate 14. Two groups of symmetrically arranged pressing rollers 15 are further arranged below the pressing plate 14. After the second lifter 13 (a hydraulic cylinder is adopted) is started, the output end drives the pressing plate 14 to lift. When the galvanized pipe is placed on the supporting roller 12 on the workbench 1, the pressing plate 14 is lowered by adjusting the second lifter 13. The two groups of symmetrically arranged pressing rollers 15 below the pressing plate 14 cooperate with the supporting roller 12. The pressing roller 15 and the supporting roller 12 apply pressure to the galvanized pipe, stably fix the galvanized pipe therebetween, and prevent the galvanized pipe from moving in the cutting process. The lifting height of the second lifter 13 can be adjusted to adapt to galvanized pipes of different diameters. For the galvanized pipe with a larger diameter, the pressing plate 14 can be appropriately raised to increase the distance between the pressing roller 15 and the supporting roller 12. For the galvanized pipe with a smaller diameter, the pressing plate 14 can be appropriately lowered to reduce the distance between the pressing roller 15 and the supporting roller 12.

[0026] In actual use, the connecting piece comprises the insertion block 16, the elastic piece and the clamping block 17, the insertion block 16 is connected with the feeding plate 6 above, the insertion block 16 is connected with the mounting groove below, the insertion block 16 is symmetrically provided with the movable groove on the front and back sides, the elastic piece and the clamping block 17 are arranged in the movable groove, the elastic piece is connected with the inner wall of the movable groove and the clamping block 17 at both ends respectively, the elastic piece comprises the spring 18 and the telescopic rod 19, the spring 18 is sleeved on the telescopic rod 19, the spring 18 and the telescopic rod 19 are connected with the inner wall of the movable groove and the clamping block 17 at both ends respectively, when the feeding plate 6 needs to be installed, the insertion block 16 of the connecting piece is inserted into the mounting groove on the sliding block 5. During the insertion process, the clamping block 17 in the movable groove symmetrically arranged on the front and back sides of the insertion block 16 is extruded by the wall of the mounting groove. Since the clamping block 17 is connected with the inner wall of the movable groove through the elastic piece (the spring 18 and the telescopic rod 19), the clamping block 17 will compress the elastic piece towards the movable groove, when the insertion block 16 is completely inserted into the mounting groove, the clamping block 17 is ejected under the elastic force of the elastic piece, and is clamped into the corresponding position of the mounting groove, so that the feeding plate 6 and the sliding block 5 are quickly connected, when the feeding plate 6 needs to be disassembled, an external force is applied to compress the elastic piece and make the clamping block 17 separate from the corresponding position of the mounting groove, then the insertion block 16 is pulled out of the mounting groove, and the feeding plate 6 can be easily taken off.
