Description

Plasma cutting machine workbench capable of accelerating water inlet and outlet

Technical Field

The invention relates to the technical field of plasma cutting equipment, in particular to a workbench of a plasma cutting machine for accelerating water inlet and outlet.

Background

Plasma cutting is a processing method in which a metal portion or a part at a notch of a workpiece is melted (and evaporated) by heat of a high-temperature plasma arc, and the melted metal is removed by momentum of high-speed plasma to form a notch, and cutting of an arbitrary shape can be realized in combination with numerical control. The plasma cutting machine can be matched with different working gases to cut various metals which are difficult to cut by oxygen, and particularly has better cutting effect on nonferrous metals (stainless steel, carbon steel, aluminum, copper, titanium and nickel); the plasma cutting machine has the main advantages that when metal with small thickness is cut, the plasma cutting speed is high, particularly when a common carbon steel sheet is cut, the speed can reach 5-6 times of that of an oxygen cutting method, a cutting surface is smooth and clean, thermal deformation is small, and a heat affected zone is almost absent.

At present, plasma cutting equipment can make metal workpiece produce very high temperature when cutting work, and some metal workpiece melting points are lower, and high temperature can make metal workpiece warp, if not in time carry out quick cooling to it, then can influence the precision of cutting.

Disclosure of Invention

The invention aims to provide a plasma cutting machine workbench for accelerating water inlet and outlet, and aims to solve the technical problem that plasma cutting equipment in the prior art cannot be rapidly cooled when cutting a metal workpiece.

In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a business turn over plasma cutting machine workstation of water with higher speed, includes casing, water tank and air compressor machine, the water tank is rectangle hollow structure and sets up in the casing to the bottom of water tank and the interior diapire fixed connection of casing, be equipped with the basin between the lateral wall of water tank and the inside wall of casing, be close to the bottom of water tank and be equipped with a plurality of wash ports all around, be close to be equipped with on the top lateral wall of water tank with equal inside gas tube and the blast pipe that is linked together, be equipped with communicating pipe between air compressor machine and the gas tube, the both ends of this communicating pipe are connected with air compressor machine and gas tube respectively, be equipped with.

Compared with the prior art, the invention has the beneficial effects that:

when the plasma cutting machine works, firstly, a workpiece to be processed is placed at the top of a water tank, the water level in the water tank is the same as the water level in a water tank formed between the water tank and a shell, when the workpiece needs to be cooled after being cut, air flows into the water tank from a communicating pipe through the work of an air compressor, so that water in the water tank is extruded out, the workpiece is soaked by the water level in the water tank, and then the air compressor is closed to keep the water level, so that the cooling step of the workpiece is completed; after the workpiece is cooled, air in the water tank is discharged from the exhaust pipe through the exhaust valve, so that water in the water tank flows back into the water tank, and when the water level in the water tank is the same as the water level in the water tank, the exhaust valve is closed, so that the workpiece can be rapidly cooled, and the purposes of reducing water consumption and production cost can be achieved; compared with the prior art, the drainage cooling mode accelerates the speed of water injection and drainage, shortens the drainage time and improves the production efficiency.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Referring to fig. 1 to 3, it can be known that a plasma cutting machine workbench for accelerating water inlet and outlet is disclosed, which comprises a casing 1, a water tank 2 and an air compressor 3, wherein the water tank 2 is of a rectangular hollow structure and is arranged in the casing 1, the bottom of the water tank 2 is fixedly connected with the inner bottom wall of the casing 1, a water tank 4 is arranged between the outer side wall of the water tank 2 and the inner side wall of the casing 1, a plurality of drain holes 5 are arranged around the bottom close to the water tank 2, an inflation tube 6 and an exhaust tube 7 which are communicated with the inside of the inflation tube are arranged on the side wall of the top close to the water tank 2, a communicating tube 8 is arranged between the air compressor 3 and the inflation tube 6, two ends of the communicating tube 8 are respectively connected with the air compressor.
