Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, and in particular relates to a saw cutting device used for metal plate processing. Background Art

[0002] In the field of mechanical processing, the cutting technology for metal plates is relatively mature. Common metal cutting methods include saw cutting, flame cutting, laser cutting and water jet cutting. Saw cutting equipment is relatively simple, easy to maintain, convenient for personnel to operate, low investment cost and widely used.

[0003] In a Chinese patent with publication number CN218224908U, a saw cutting device for metal plate processing is mentioned. The device of this patent follows the movement of the saw blade through an extrusion structure, and squeezes both sides of the cutting position of the metal plate to be processed to ensure its axial and radial stability, avoid edge collapse and uneven cutting surface near the tail end, and improve processing quality.

[0004] However, in the initial state of the device of this patent, the saw blade can only be located at one end of the metal plate, and the metal plate is cut from the end of the metal plate, rather than being located at the top of the metal plate. This results in the clamping wheel being located only at one end of the metal plate, and the clamping wheel cannot clamp the metal plate from the top of the metal plate at the beginning of cutting (if the clamping wheel clamps the metal plate from the top of the metal plate in the initial state, the metal plate will conflict with the saw blade in position), and the clamping wheel will be squeezed downward by the elastic force of the spring part, resulting in the clamping wheel and the metal plate not being in the same horizontal plane in the initial state, and the height of the clamping wheel is lower than the height of the metal plate. When the clamping wheel moves forward with the saw blade, the clamping wheel is likely to collide with the metal plate, and cannot smoothly move to the top of the metal plate and clamp the metal plate, affecting the cutting work. Utility Model Content

[0005] The utility model aims to provide a saw cutting device for metal plate processing, so as to solve the problems in the prior art that the clamping wheel cannot clamp the metal plate from the beginning and the clamping wheel may not be able to move smoothly above the metal plate.

[0013] Preferably, a clamping mechanism for clamping the metal plate is provided on the top of the workbench.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1.

[0025] Specifically, the clamping mechanism 7 includes a slider 71, the internal thread of the slider 71 is connected to a screw rod 72, the lower end of the screw rod 72 is rotatably installed with a pressure plate 73, the bottom of the pressure plate 73 is fixedly connected to a telescopic rod 74, the lower end of the telescopic rod 74 is fixedly connected to a support 76, and two clamping wheels 77 are rotatably installed inside the support 76.

The metal plate is placed under the clamping wheel 77, and the clamping wheel 77 can squeeze the metal plate downward by the elastic force of the spring 75. The height of the pressure plate 73 can be adjusted by rotating the screw rod 72, thereby controlling the downward squeezing force of the clamping wheel 77, so that the equipment is suitable for metal plates of different thicknesses.

[0026] More specifically, a motor 9 is fixedly installed on the side of one of the fixed rods 5, and a bidirectional screw 8 is fixedly connected to the output end of the motor 9. The thread on the outer surface of the bidirectional screw 8 is divided into two sections with opposite rotation directions. The bidirectional screw 8 is rotatably installed between the two fixed rods 5. The driving motor 9 can drive the bidirectional screw 8 to rotate. The two sliders 71 are respectively threadedly connected to the two ends of the bidirectional screw 8, and the upper ends of the sliders 71 are slidably connected to the bottom of the guide rod 6. The rotation of the bidirectional screw 8 can drive the two sliders 71 to slide in opposite directions, so that the spacing between the two sliders 71 can be adjusted, which is convenient for adjusting the position of the clamping wheel 77 according to the width of the metal plate, and optimizing the clamping effect of the clamping wheel 77 on the metal plate.

[0027] Furthermore, an installation groove 10 is opened inside one of the connecting rods 3, and a motor 2 13 is fixedly installed inside the installation groove 10.

The end of the metal plate can be clamped by the clamping wheel 77, and then the metal plate is clamped and fixed by the clamping mechanism 12. Then the saw blade 4 is driven to cut the metal plate. When the connecting rod 3 drives the saw blade 4 forward, it can also drive the clamping wheel 77 forward. The clamping wheel 77 can squeeze both sides of the metal plate during the cutting process of the saw blade 4 to ensure its axial and radial stability. This solution can place the metal plate under the clamping wheel 77 before cutting. The clamping wheel 77 can clamp the metal plate at the beginning of cutting to ensure the stability of the cutting and ensure that the clamping wheel 77 can move smoothly on the metal plate.
