Description

Technical Field

[0001] The invention belongs to the field of pipe cutting equipment, and in particular, relates to an automatic loading and unloading device for a pipe cutting machine and a working method thereof. Background Art

[0002] With the rapid development of industry, the efficiency and precision of wire cutting and flame cutting can no longer meet the needs of customers, and customers have high requirements for machine tool stability and efficiency. Here we have conducted various studies on laser tube cutting machines and added semi-automatic feeding mechanisms and fully automatic blanking devices to the laser tube cutting machines.

[0003] The common automatic feeding mechanism uses a cloth belt to stack the workpieces, and then multiple motors cooperate to control the feeding arm to take the materials and feed them. However, this feeding mechanism has a complex structure, multiple motion trajectories, poor stability, and low compatibility with special-shaped tubes. In addition, the feeding mechanism with a stacking mechanism will have the following problems:

[0004] 1. Due to the problem of belt material, the uncontrollable deformation will cause errors in the horizontal direction of the pipe. When switching between multiple pipes, a long initial adjustment cycle is required, and long-term work will cause rapid wear and short life;

[0005] 2. Due to the single-arm single-motor control, there are mechanical errors in the synchronization of multiple feeding arms during use, and the uncontrollable range of cutting error value is wider.

[0006] Common pipe cutting equipment blanking devices are just a single blanking slide, or a blanking mechanism with floating rollers. There are some unstable factors in the above two lifting workbenches. The independent blanking slide frame will have the following problems: due to its simple structure, the blanking is relatively close to the processing area during use, and the blanking mechanism has no slag and dust removal structure, which will cause slag to spatter, thus sticking to the surface of the finished product and affecting product quality. The blanking mechanism with floating rollers will have the following problems: the initial installation is more troublesome, and the compatibility with some large and heavy pipes is poor, and it is only suitable for some small or medium-sized pipes. Summary of the invention

The first motor (121) is turned on after receiving the signal, and the first rotating shaft (122) rotates along with the first motor (121). The horizontal mechanical conveying claw (1232) connected to the first rotating shaft (122) via a transmission belt (124) is driven by the first rotating shaft (122); (3) The horizontal mechanical conveying claw (1232) moves to the position directly below the pipe, the vertical mechanical conveying claw (1234) places the pipe on the horizontal mechanical conveying claw (1232), the horizontal mechanical conveying claw (1232) conveys the pipe to the support block (43) of the workbench (4), the other end of the pipe is supported by the chuck (421) of the movable block (42), the movable block (42) moves along the track (411), the pipe moves to the laser pipe cutting machine (2), and the laser pipe cutting machine (2) performs cutting processing; (4) During the pipe cutting process, the connecting arm (33) drives the slag collecting box (32) into the pipe, and the slag collecting box (32) moves below the cutting point to ensure that the cutting slag falls into the box. At the same time, the dust collector (351) is started, and the smoke and dust generated during the cutting process are sucked into the dust removal device (35) by the dust removal pipe (352); (5) After cutting is completed, the finished pipe is sleeved on the outside of the connecting arm (33), the connecting arm (33) retreats to its original position, and the finished pipe is blocked by the baffle (312) and falls onto the landslide (311), and then falls onto the conveyor belt (341) through the landslide (311), and is conveyed by the conveying device (34) to the finished product collection location.
