4000mm Gantry Type CNC Plasma Cutting Machine with vertical and horizontal cutting

1. ☆ Brief introduction

CNC series digital cutting machine is a kind of newly researched and developed efficient automatic cutting equipment for steel plate to support processing of metallic parts based on absorbing domestic and overseas advanced software and hardware technology and it can perform vertical and horizontal cutting and cutting on any position of arc curve, which is featured with high cutting surface precision and small deformation. The equipment is featured with appropriate structure, easy operation, and advanced technology etc. CNC flame cutting is a traditional thermal cutting method, which is applicable to cut the carbon steel plate with good quality and the cutting thickness is 6-150mm. CNC plasma cutting machine is applicable to cut stainless steel and nonferrous steel with quick speed, good cutting surface roughness, high precision and small deformation. It is a best choice to get the higher quality of cutting metal material. CNC cutting machine is widely applicable to the automobile, shipbuilding petrochemical industry, boilers, pressure vessels, construction machinery, light industrial machinery and other industries.

6. ☆ Machine introduction

CNC series digital cutting machine is a new design machine in good working. Its overall looks nice, lighter, smaller accelerate force, smooth operation and to be used widely. Its main functions and features as below:

• Main structure:

CNC series digital control cutting machine is made up of gantry frame (made up of girder and a couple of end girders), main driven rail, transverse planker, lifting cutting torch, vertical strip cutting torch, cutting platform, seton component, gas path system, electric control and servo control system, etc.

• Gantry frame:

Girder: Square beam welding structure for removing stress is employed for the girder. Binding surface of the girder adopts key groove structure for facilitating binding end girder. Traveling surface of each guide track has undergone precision machining with sound toughness and precision. The transverse rack is fixed by the bolt on the track which is processed by girder. That is convenient for replacement and adjustment. One of the flank of the girder installed 45# high-grade carbon steel track. After tempering, the surface of track is with high rigidity and hard wearing to realize the usage of transverse planker. According to the requirement, the machine can be equipped with rail for the movement of 9 pieces (depends on customers) of multi-head vertical strip cutting torch at another side of the girder. This rail is processed in advance and formed as assembly type to meet the needs of multi-head vertical strip gas cutting.

End girder: Active end girder adopts sheet material box type welding , and removes welding stress after welding, which is compact and nice-looking and process the location key gutter with binding surface of the girder to ensure installation size. AC servo motor made in Japan and reducer made in Germany are installed in the driven end beam, which is also controlled by the driven device. The transmission device is installed on the guide sliding plate, with spring pressing device installed on one flank, to ensure joggle and transmission of gear and rack to make the equipment travel stably and meet the requirement of rate change. Horizontal guide wheel is installed on both ends of the end girder, which is used to adjust pressing content of the concentric wheel on the rail.

The gantry frame is made up of girder and end girder at both ends, with locating by key gutter at one end; it combines high strength bolts to ensure stable operation of the equipment without any deviation. Dust wiper is installed at both end surface of the end girder. During operation, it removes impurities on the rail surface to ensure requirements of processing and thermal cutting to facilitate cutting. During acceleration, deceleration and relocation, the max traveling precision of the equipment can be guaranteed.

• Main and assistant track:

High strength rail processing is used for longitudinal rail at both sides. Precision processing is made for top surface and side surface of the rail, and precise processing rack is installed on the external side of the rail to make the drive motor drive transmission of gear and rack couple. Connect the rail with pressing plate, tie plate and connecting shaft and fix it on the supporting beam. The supporting beam is a welding part and shall be made by customers. It shall remove stress and ensure straightness, parallelism and horizontality of the guide rail, precision processing method and appropriate processing technology ensure operation precision of manufacturing, installation and product precision to make sound joggle of gear and rack with stable operation.

• Lifting cutting torch:

To realize lifting of the cutting torch, transmission screw couple and straight line bearing are used for the numerical control cutting machine. TWT gear DC motor made in Taiwan is used as transmission device. LM straight line bearing is used for upper and lower moving. The cutting torch moves freely on the lifting rod the operation is controlled by travel switch to realize non-special lifting. The cutting torch group includes one set of numerical control cutting torch and ignition device, plasma cutting torch, and the others can selected by user’s requirement. The cutting torches are connected with fixing plate and lifting rod to ensure flexible move of the cutting torch.

• Gas path system

Design of the gas path system shall ensure safe and reliable operation. It is comprised of two parts. One is the customer’s supplied gas supply device and gas source, collective gas supply or junction bus gas supply, with oxygen purity 99.7% and propane 86%. The other is required air way by manufacturer, namely, gas source box, distribution row and numerical control cutting torch (vertical strip cutting torch) to form an air way system. The gas source box holds 3 reduction valves and pressure gauges. Oxygen enters in two ways and propane enters reduction system of the gas source box. After pressure reduction, required gas source is obtained, oxygen pressure 0.98Mpa and acetylene pressure 0.14Mpa, the gas source enter distribution row through the joint pipe, which is made up of 3 pipe rows and fix it on the main beam surface with clamps. The distribution row is the main body of the distribution structure of the cutting torch, one way is connected to the two groups of numerical control cutting torch through the dragging chain of MS and gas source pipe,. Backfire device is installed on the air way pipe (cutting torch) to prevent backfire to make operation safe and reliable. Distribution of gas source pressure and flow is completed by rotating hand value of reduction value and cutting torch. Cutting pressure is selected according to thickness of cutting steel plate. Selection of the parameters depends on familiarized operation.
