DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Laser cutting machines are often required when processing metal plates. When using existing laser cutting machines, workers are usually required to manually place the plates at the processing position. Metal plates are usually heavy, and manual handling and loading require a lot of physical strength from workers, which can easily lead to fatigue and physical injuries. It takes a lot of time and manpower, especially in mass production. This manual operation will significantly reduce overall production efficiency.

[0023] To solve the defects of the above equipment in the feeding process, please refer to Figure 1-Figure 5The utility model provides a metal plate feeding structure for a laser cutting machine, which can automatically push the metal plate to the processing position, realize automatic feeding of the metal plate, reduce the frequency and intensity of manual handling and feeding required by workers, not only improve the working comfort of workers, but also greatly improve the overall production efficiency. The device uses a workbench 1 and a sub-table 2 as the basic structure. A cutting piece 4 is installed on the top of the workbench 1. The cutting piece 4 is specifically set as a laser cutting machine for curved cutting of metal plates. The laser cutting machine is a prior art, and its component composition and cutting principle are not described in detail here. A feeding mechanism 3 is set between the workbench 1 and the sub-table 2. The feeding mechanism 3 is used for automatic feeding of metal plates. The metal plate can be pushed to the bottom of the cutting piece 4 through the feeding mechanism 3, and then the cutting piece 4 can cut the metal plate. The feeding mechanism 3 includes a first slide 31 and a second slide 32. The first slide 31 is for the metal plate to slide. The first slide 31 and the second slide 32 are both fixedly installed on one side of the workbench 1, and the first slide 31 is set above the second slide 32. The height of the first slide 31 is set to The height of the workbench 1 is not lower than that of the workbench 1. The metal plate can be slid onto the workbench 1 through the first slide 31. The end of the first slide 31 is fixedly connected to a material frame 33 for loading the metal plate. The material frame 33 is composed of two symmetrically arranged L-shaped plates. The metal plates to be processed can be stored in batches in the material frame 33. The interior of the second slide 32 is provided with a plurality of pushing members 34 for pushing the metal plate onto the workbench 1. A connecting plate 36 is commonly installed at the bottom of the plurality of pushing members 34. A driving member 35 is provided at the bottom of the connecting plate 36. The driving member 35 can drive the connecting plate 36 and the plurality of pushing members 34 on the connecting plate 36 to slide back and forth. The reciprocating sliding of the pushing members 34 can push the metal plates one by one onto the workbench 1, thereby realizing automatic loading of the metal plates and improving the overall production efficiency.

[0024] In order to achieve the pushing effect of the metal plate by the reciprocating sliding of the pusher 34, refer to Figure 3-Figure 4, a support seat 341 is specially provided, and the support seat 341 is slidably installed in the second slide 32. A rotating shaft 342 is rotatably installed inside the support seat 341, and a push plate 343 is fixedly connected to the outside of the rotating shaft 342. Torsion springs 344 are sleeved on both ends of the rotating shaft 342. One side of the support seat 341 is fixedly connected to a limiting plate 345. The inner bottom wall of the material frame 33 is flush with the metal plate. When the metal plate is placed in the material frame 33, the height of the push plate 343 is higher than the height of the lowest metal plate. The metal plate can be pushed along the first slide 31 by the push plate 343. Due to the setting of the limiting plate 345, the steering of the push plate 343 can be limited to prevent the push plate 343 from moving to The rear flipping can ensure that the push plate 343 can push the metal plate forward when it slides forward. After the metal plate is successfully pushed onto the workbench 1, the support seat 341 drives the push plate 343 to slide backward, and the push plate 343 is against the metal plate to be processed on the first slide 31, so that the push plate 343 flips forward and slides from the bottom of the metal plate to the back of the metal plate. The rotation of the push plate 343 drives the torsion spring 344 to deform, and the deformation of the torsion spring 344 generates torque. When the push plate 343 slides out from the bottom of the metal plate, the push plate 343 can be flipped and reset by the torque of the torsion spring 344, which is convenient for pushing the metal plate forward next time. Such a cycle can realize automatic pushing and loading of the metal plate.

[0025] In order to realize the reciprocating sliding of multiple pushing members 34, a first connecting rod 351 is provided. The first connecting rod 351 is rotatably installed at the bottom of the connecting plate 36, and the lower end of the first connecting rod 351 is rotatably installed with the second connecting rod 352. A bracket 353 is fixedly connected to one side of the sub-table 2. The end of the second connecting rod 352 away from the first connecting rod 351 is rotatably installed at the end of the bracket 353. A servo motor 354 is fixedly installed on one side of the bracket 353. The output end of the servo motor 354 passes through the bracket 353 and is fixedly connected to the end of the second connecting rod 352. Driving the servo motor 354 can drive the second connecting rod 352 to rotate. The rotation of the second connecting rod 352 drives the first connecting rod 351 to rotate. The rotation of the first connecting rod 351 pulls the connecting plate 36 to slide reciprocally. The reciprocating sliding of the connecting plate 36 drives multiple pushing members 34 to slide synchronously. The pushing members 34 can push the metal plates onto the workbench 1 one by one, so as to realize orderly loading of the metal plates.

[0026] Reference Figure 1 and Figure 5 As shown, reinforcing rods 37 are fixedly connected to both sides of the material frame 33, and the ends of the reinforcing rods 37 are fixedly installed on the top of the sub-platform 2. Positioning plates 38 are fixedly connected to both sides of the inner wall of the material frame 33. The reinforcing rods 37 fix the material frame 33. Since the metal plate is heavy, the setting of the reinforcing rods 37 can enhance the stability of the material frame 33. The positioning plates 38 help to place the metal plates more neatly. Put the metal plate into the material frame 33 so that its side faces are against the positioning plates 38.

[0027] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
