Description

Technical Field

[0001] The utility model relates to the technical field of plasma cutters, in particular to a protective guide rail structure for a plasma cutter. Background Technique

[0002] A plasma cutter is a processing and cutting device that uses the heat of a high-temperature plasma arc to locally melt and evaporate the metal at the workpiece cutting edge, and discharges the molten metal by the momentum of the high-speed plasma to form a cutting edge; with different working gases, the plasma cutting can cut various metals that are difficult to cut by oxygen cutting, especially for non-ferrous metals such as stainless steel, aluminum, copper, titanium, nickel, etc., and the cutting effect is better.

[0003] The guide rails in the existing plasma cutters are mainly used to hold the metal plates to be cut, and are composed of multiple groups of strip-shaped high-strength metal plates. However, after the cutter is used for a long time, the cutting flame will more or less damage the loading track, which will in turn affect the flatness of the plate placement and needs to be replaced regularly. This not only increases the cost, but also is time-consuming and laborious. Content of the Utility Model

[0008] The utility model can be further configured in a preferred example as: the guide rail assembly is provided with four groups symmetrically arranged with respect to the cutting body.

[0009] The utility model can be further configured in a preferred example as: clamping grooves for the mounting frame to be clamped are formed on both sides of the rail car.

[0011] In a preferred embodiment of the present utility model, it can be further configured that a material feeding roller is installed on the material loading plate.

[0012] The above technical solution of the present utility model has the following beneficial technical effects:

[0013] Through the guide rail assembly, the present utility model can use the support roller to suspend and carry the plate to be cut. At the same time, the motor can also drive the support roller to rotate and convey the plate. During the cutting process of the plate, when the cutting tool moves to the right, the cylinder group on the left will push the rail car to move to the right, so that the material loading plate can hold the plate to be cut. After the cutting is completed, the electric telescopic rod contracts and moves to pull the bottom of the support plate, so that the end of the material loading plate tilts downward, and the plate slides down along the material loading plate. This solution does not require a guide rail to be provided under the plate, avoiding damage by the cutting flame, and has high practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0021] The following describes a protective guide rail structure of a plasma cutting machine provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0022] Combined withFigure 1-2 As shown in the figure, a protective guide rail structure of a plasma cutting machine provided by the utility model includes a cutting machine body 100 and a guide rail assembly 200; the guide rail assembly 200 is arranged on the cutting machine body 100.

[0023] Among them, the guide rail assembly 200 includes a driving mechanism arranged on both sides of the bottom of the cutting machine body 100, a rail car 210 connected to the driving mechanism, rollers 220 installed at the bottom of the rail car 210, and a material control mechanism arranged on the rail car 210; the material control mechanism includes a mounting frame 230 clamped in the rail car 210 and connected to the driving mechanism, a motor 240 installed above the roller 220, a support roller 250 fixed to the driving end of the motor 240, a roller frame 260 installed on the mounting frame 230 for the support roller 250 to be assembled, a support plate 270 hinged and installed at the end of the rail car 210 and connected to the driving mechanism, and a material loading plate 280 installed on the top of the support plate 270. Through the guide rail assembly 200, the support roller 250 can be used to suspend and carry the plate to be cut, and at the same time, the motor 240 can also drive the support roller 250 to rotate and convey the plate. During the plate cutting process, when the cutting tool moves to the right, the cylinder group 310 on the left side will push the rail car 210 to move to the right, so that the material loading plate 280 can hold the plate to be cut. After the cutting is completed, the electric telescopic rod 320 contracts to pull the bottom of the support plate 270, so that the end of the material loading plate 280 tilts downward, and the plate slides down along the material loading plate 280. This solution does not require a guide rail to be arranged under the plate, avoiding being damaged by the cutting flame, and has high practicability.

[0024] Specifically, the driving mechanism includes a cylinder group 310 respectively connected to the mounting frame 230 and the rail car 210, and an electric telescopic rod 320 installed on the mounting frame 230 and connected to the bottom of the support plate 270. The driving mechanism can drive the rail car 210 and the mounting frame 230 to move respectively, and can also drive the support plate 270 to tilt. When driving the rail car 210 to move, the mounting frame 230 will also remain stable within the range of the card slot 211, without affecting their respective driving operations.

[0025] Furthermore, the cylinder group 310 is composed of three cylinders.

[0026] Furthermore, the guide rail assembly 200 is provided with four groups symmetrically arranged with respect to the cutting machine body 100. The four groups of guide rail assemblies 200 can support the plate at the four corners of the plate, which is relatively stable.

[0027] On the other hand, card slots 211 for the mounting frame 230 to be clamped are opened on both sides of the rail car 210, which can enable the mounting frame 230 to move stably on the rail car 210, and is relatively reasonable.

[0028] It should be noted that a cushion pad 231 is fixed on the mounting bracket 230 above the support roller 250, which can play a cushioning role for the plate to be cut on both sides and prevent the mounting bracket 230 from being worn.

[0029] Furthermore, a feeding roller 281 is installed on the material loading plate 280. By means of the feeding roller 281, the plate can slide more smoothly when the material loading plate 280 is inclined, which is quite practical.

[0030] The working principle and usage process of the present utility model are as follows: First, place the plate to be cut between the support rollers 250, and then use the support rollers 250 to suspend and carry the plate to be cut. During the cutting process of the plate, when the cutting knife moves to the right, the cylinder group 310 on the left will push the rail vehicle 210 to move to the right, and vice versa, so that the material loading plate 280 holds the plate to be cut off. After the cutting is completed, the electric telescopic rod 320 makes a contraction movement, pulling the bottom part of the support plate 270 to displace, and further causing the end of the material loading plate 280 to tilt downward. Finally, the plate slides down along the material loading plate 280.

[0031] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
