A desktop plasma cutting machine

Abstract

The present invention relates to the field of cutting machines, specifically a desktop plasma cutting machine, comprising a cutting module, a feeding module and a loading module. In the present invention, a motor simultaneously rotates a small curved rod and a large curved rod, and the small curved rod affects the large annular plate, the plate body, the push plate and the baffle rod to move back and forth. When the push plate slides toward the discharge frame, the push plate is restricted by the baffle rod, and the push plate and the pipe-like objects in the arc plate are interference-fitted. Then, the pipe-like objects are pressed into the discharge frame, and the pipe-like objects are neatly arranged in the discharge frame. When the pipe-like objects move to the front end of the discharge frame, the pipe-like objects fall and are received by the discharge plate. Then, when the pipe-like objects are transversely coaxial with the limiting sockets, the large curved rod presses the pipe-like objects one by one into multiple limiting sockets through the small annular plate, the connecting rod and the push rod, ensuring that the plasma cutting machine body has sufficient material source and mechanized continuous loading. Then, the loaded blanks can limit themselves, effectively improving the cutting efficiency.

Description

Technical Field

[0001] The present invention relates to the field of cutting machines, in particular to a desktop plasma cutting machine. Background Art

[0002] A plasma arc cutting machine is a machine that uses plasma cutting technology to process metal materials. Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially melt (and evaporate) the metal at the workpiece cut, and then uses the momentum of the high-speed plasma to expel the molten metal to form the cut.

[0003] In order to improve the shaping effect of the object after cutting, the object needs to be fixed after being placed at the bottom of the cutting machine before cutting. In addition, when the existing plasma cutting machine cuts according to this step, the placement and fixation of the object are not continuous. Each of these steps takes a certain amount of time, resulting in very low cutting efficiency. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in the present invention is:

[0006] The cutting tool of the present invention is a kind of table-type plasma cutting machine, comprising a cutting module, a feeding module and a feeding module, wherein the cutting module comprises a supporting table frame, a limiting guide plate installed on the top of the supporting table frame, an L-shaped support plate detachably connected to the limiting guide plate, a T-shaped shaft which is transversely and movably passed through the L-shaped support plate, a rotating drum which is sleeved on the outer side of the T-shaped shaft, a placing table connected to the top of the L-shaped support plate, a slide which is slidably installed on the top of the placing table, a plasma cutting machine body connected to the top of the slide plate, a motor connected to the top of the limiting guide plate, a small gear sleeved on the outer side of the motor output shaft, a large gear which is meshed with the bottom of the small gear and movably connected to the L-shaped support plate, a tooth plate connected to the bottom of the T-shaped shaft, a limiting jack is provided on the rotating drum, the tooth plate is movably meshed with the large gear, the plasma cutting machine body and the motor are electrically connected to an external PLC, and the feeding module is a kind of table-type plasma cutting machine, comprising a table-type plasma cutting machine, a table-type plasma cutting machine and a feeding module. The gear train is connected with the gear train by the large gear and the gear train is connected with the gear train by the large gear, and the gear train is connected with the gear train by the large gear.

[0007] By adopting the above technical solution, the motor rotates the small curved rod and the large curved rod at the same time. The small curved rod affects the large annular plate, the plate body, the push plate and the baffle to move back and forth. When the push plate slides toward the discharge frame, the push plate is restricted by the baffle, and the push plate is interference fit with the pipe objects in the arc plate. Then the pipe objects are pressed into the discharge frame and neatly arranged in the discharge frame. When the pipe objects move to the front end of the discharge frame, the pipe objects fall and are received by the discharge plate. Then, when the pipe objects are horizontally coaxial with the limit sockets, the large curved rod will press the pipe objects one by one into multiple limit sockets through the small annular plate, the connecting rod and the push rod, ensuring that the plasma cutting machine body has sufficient material source and mechanized continuous loading. Then the loaded blanks can limit themselves, effectively improving the cutting efficiency.

[0008] In a preferred example, the present invention can be further configured as follows: the L-shaped support plate and the T-shaped shaft are both made of alloy material, and an annular slideway is retained between the L-shaped support plate and the T-shaped shaft.

[0009] In a preferred example, the present invention can be further configured as follows: a plurality of ball seats are provided inside the annular slideway, and the plurality of ball seats are equally spaced and annularly surrounded on the outside of the T-shaped shaft, one side of the ball seat is fixedly connected to the outer wall of the T-shaped shaft, and the other side of the ball seat is fitted with the outer wall of the L-shaped support plate.

[0010] In a preferred example, the present invention can be further configured as follows: a T-shaped rod is threadedly mounted on the slide, and the bottom end of the T-shaped rod is fitted with the top of the placement table.

[0011] In a preferred example, the present invention can be further configured as follows: the limiting jacks are provided in a plurality, and the plurality of limiting jacks are arranged in a ring shape with equal spacing.

[0012] In a preferred example, the present invention can be further configured as follows: the rubber pad is set to be semicircular, and the height of the rubber pad is flush with the top of the feed port.

[0013] In a preferred example, the present invention can be further configured as follows: a rectangular opening is provided on the rear side of the limiting guide plate, and the plate body movably passes through the rectangular opening.

[0014] In a preferred example, the present invention can be further configured as follows: wear-resistant sleeves are installed on the top and bottom ends of the large annular plate, and the two wear-resistant sleeves are both in contact with the inner wall of the limiting guide plate.

[0015] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0016] 1. In the present invention, the motor drives the small crank arm and the large crank arm to rotate at the same time. The small crank arm affects the large annular plate, the plate body, the push plate and the stop rod to move back and forth. When the push plate slides toward the discharge frame, the push plate is restricted by the stop rod. The push plate and the pipe objects in the arc plate have an interference fit. Then the pipe objects are pressed into the discharge frame and neatly arranged in the discharge frame. When the pipe objects move to the front end of the discharge frame, the pipe objects fall and are received by the discharge plate. Then, when the pipe objects are transversely coaxial with the limiting sockets, the large crank arm presses the pipe objects one by one into multiple limiting sockets through the small annular plate, the connecting rod and the push rod, ensuring that the plasma cutting machine body has sufficient material source and mechanized continuous loading. Then the loaded blanks can limit themselves, effectively improving the cutting efficiency.

[0017] 2. In the present invention, the external PLC starts the motor, the motor drives the large gear to rotate with the small gear, and then the large gear drives the T-shaped shaft and the rotating drum with the toothed plate. When the objects in the rotating drum rotate to the bottom of the plasma cutting machine body, the external PLC starts the plasma cutting machine body, thereby completing the cutting of the objects. The objects are cut continuously, which effectively improves the cutting efficiency.

[0018] 3. In the present invention, a wear-resistant sleeve is provided to prevent the large annular plate from shaking left and right during translation, thereby making the translation of the large annular plate stable. At the same time, it also reduces the degree of wear of the large annular plate and the limiting guide plate, thereby ensuring the service life of the large annular plate and the limiting guide plate and improving the structural stability of the device.
