Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and more specifically, to a device for supporting materials during the material feeding process of a cutting machine, particularly a cutting machine material support frame designed specifically for cutting long materials. Background Technology

[0002] Flame cutting and plasma cutting are widely used in steel and machining industries. While their equipment costs are relatively low and they are suitable for cutting thicker steel plates, flame cutting has several drawbacks. It generates a large amount of heat during cutting, which can easily cause steel deformation and affect cutting accuracy; the cutting speed is slow, and molten slag remains on the cut edges, requiring subsequent cleaning and processing, increasing workload and costs. As industry demands for cutting technology increase, the required precision in steel processing is also rising. However, in the cutting of long steel sections, there is a lack of effective support devices, and existing technologies cannot meet the requirements. Therefore, there is an urgent need for a cutting machine support device that can improve this situation. Summary of the Invention

[0003] This invention provides a device specifically designed for supporting the material cutting of cutting machines. It primarily addresses the issue of long and heavy steel materials during cutting operations by providing stable physical support to prevent sagging, bending, and deformation due to their own weight. This ensures the steel remains flat during the cutting process, thereby improving cutting accuracy and producing finished products with neat edges and precise dimensions. Furthermore, the device can flexibly adjust the material height according to the height of the cutting machine, optimizing the manual operation process and increasing cutting efficiency.

[0004] The technical means adopted in this utility model are as follows:

[0005] A portable cutting machine material support rack, comprising:

[0006] The base is made of three square steel bars welded into an I-shaped frame, which provides stable support for the overall structure.

[0007] The base is made of 40mm square steel. The two horizontal square steels that form the I-shaped frame are 300mm long, and the longitudinal connecting square steel is 400mm long. The longitudinal connecting square steel is located at the geometric center of the two horizontal square steels and is fully welded.

[0008] The fixed columns consist of two steel pipes, which stand vertically on both ends of the longitudinal connecting square steel of the base. They are fitted with sleeves, which are fitted with the fixed columns with clearance. The two sleeves are welded and fixed by the rising frame square steel, forming a fixed structure frame that can slide up and down.

[0009] The rotary feed mechanism includes bearings, steel pipes, and steel plates. The bearings are embedded in both ends of the steel pipes. Bolts pass through the inner rings of the bearings and are fastened with nuts I. The outer rings of the bearings are spot-welded to the steel pipes to form a rotary mechanism that allows the steel pipes to rotate freely. The steel plates are welded onto the sleeves. A U-shaped groove is cut on the top of the steel plates. The rotary mechanism is embedded in the U-shaped grooves and fastened with nuts II.

[0010] The lifting mechanism consists of a screw, nut III, handwheel, and rising frame square steel. One end of the screw is welded to the center point below the rising frame square steel, and the other end of the screw extends through a pre-set through hole in the longitudinal connecting square steel to the bottom of the longitudinal connecting square steel. The handwheel is made with nut III as the center and is installed on the screw between the rising frame square steel and the longitudinal connecting square steel through the cooperation of nut III and screw 11. The lifting of the fixed structure frame is achieved by rotating the handwheel.

[0011] Furthermore, the steel pipe used for the fixed column has an outer diameter of 20mm and an inner diameter of 16mm, and the gap between the sleeve and the fixed column on one side is maintained between 0.5mm and 1.5mm.

[0012] Furthermore, the inner diameter of the bearing and the outer diameter of the steel pipe are fitted together with an interference fit.

[0013] Furthermore, the steel plate is 100-150mm long, 50-70mm wide, and 2-5mm thick.

[0014] Furthermore, the thickness of the square steel of the rising frame is not less than 40mm, the outer diameter of the handwheel is 250-290mm, and the screw and nut III can realize the lifting and lowering of the fixed structure frame by rotating the handwheel.

[0015] Furthermore, the surface treatment process for each component of the device is selected according to the operating environment. In humid and corrosive environments, galvanizing and passivation are adopted, and the coating thickness is not less than 15μm.

[0016] Compared with the prior art, the present invention has the following advantages:

[0032] like Figure 1 and Figure 2 As shown,

[0033] (I) Overall Structural Design

[0034] The core structure of the portable cutting machine material support includes a base 1, a fixed column 2, a sleeve 3, a rising frame square steel 4, and a rotating feed mechanism and a lifting mechanism.

[0035] Base 1: Constructed from three carefully selected 40mm square steel bars, forming an I-shaped frame through precise welding. The two horizontal square steel bars are precisely 300mm long, providing a stable lateral support foundation for the entire device. The longitudinal connecting square steel bar is 400mm long and precisely located at the geometric center of the two horizontal square steel bars, connected using a full welding process to ensure structural strength and form a stable load-bearing platform that effectively distributes the pressure applied by the cutting material.

[0036] Fixed Column 2: Two steel pipes with an outer diameter of 20mm and an inner diameter of 16mm are vertically and precisely erected on both ends of the longitudinal connecting square steel of the base 1, providing vertical support for the device. An outer sleeve 3 is added, and the gap between the sleeve 3 and the fixed column 2 on one side has been repeatedly tested and maintained between 0.5mm and 1.5mm. This ensures that the fixed column 2 slides smoothly within the sleeve 3, enabling height adjustment, while preventing excessive gaps that could lead to structural loosening. The two sleeves 3 are firmly welded together by the rising frame square steel 4, forming a stable and flexibly sliding fixed structural frame to adapt to different cutting height requirements.

[0037] Rotary feed mechanism: This mechanism consists of bearing 5, steel pipe 6, and steel plate 7 working in tandem. The inner diameter of bearing 5 and the outer diameter of steel pipe 6 are tightly fitted with an interference fit. The interference fit is optimized to ensure a stable connection between bearing 5 and steel pipe 6 while allowing for free rotation. Bolt 8 passes through the inner ring of bearing 5 and is reliably tightened with nut I9. The outer ring of bearing 5 is spot-welded to steel pipe 6, forming a stable rotating support shaft. Steel plate 7 is welded to a key position on sleeve 3. Its dimensions are carefully designed: 100-150mm long, 50-70mm wide, and 2-5mm thick. A precise U-shaped groove is cut into the top, allowing the rotating mechanism to be precisely fitted into the U-shaped groove and tightened with nut II10. This enables the cutting material to be fed smoothly and continuously to the cutting tool with the assistance of the rotary feed mechanism, improving cutting efficiency.

[0038] The lifting mechanism, consisting of screw 11, nut III 12, handwheel 13, and rising frame square steel 4, forms the key height adjustment component. One end of screw 11 is connected to the center point below the rising frame square steel 4 using a high-strength welding process, while the other end extends through a pre-drilled hole in the longitudinal connecting square steel to its lower part. Handwheel 13, centered on nut III 12, is made of a mechanically sound material with an outer diameter controlled between 250-290mm for easy gripping and force application by the operator. Through the precise fit between nut III 12 and screw 11, mounted on screw 11 between the rising frame square steel 4 and the longitudinal connecting square steel, the operator can easily raise and lower the fixed frame by simply rotating the handwheel, quickly adjusting to the required cutting height, making operation convenient and efficient.

[0039] (II) Surface Treatment Process

[0040] Considering the complex operating environments the equipment may face, the surface treatment processes for each component can be flexibly selected according to actual conditions. In humid and corrosive environments, advanced galvanizing and passivation technologies are employed to ensure a coating thickness of no less than 15μm, effectively preventing rust and corrosion and extending the service life of the equipment. In general dry environments, conventional protective treatments such as powder coating can also be used, which not only protect the components but also make the equipment look aesthetically pleasing and clean.

[0041] (I) Example 1: Application in a small metal processing plant

[0042] In small metal processing plants, it is often necessary to cut metal profiles of different lengths and specifications, such as aluminum profiles and stainless steel angle bars. This portable cutting machine support rack offers significant advantages.

[0043] Installation and Debugging: Move the material support frame to the cutting area. Due to its compact structure and suitable weight, it can be easily placed by a single person. Adjust the height of the fixed structure frame by rotating handwheel 13 according to the length of the metal profile to be cut, so that the support height of the material support frame is slightly lower than the cutting part of the profile, facilitating subsequent operations. For example, when cutting an aluminum profile with a length of 1.5m and a thickness of 20mm, rotate handwheel 13 clockwise to raise screw 11, causing the rising frame square steel 4 to rise to the appropriate position. At this time, the fixed column 2 slides smoothly within the sleeve 3. After adjustment, confirm the height by observing the preset scale markings on the device (simple scales can be set on the fixed column or the rising frame square steel, with an accuracy of ±1mm).

[0044] Cutting operation: Place one end of the aluminum profile on the base 1 and push the profile along the steel plate 7 of the rotating feed mechanism. Due to the smooth and unobstructed rotation mechanism composed of bearing 5 and steel pipe 6, the profile can easily feed towards the cutting tool. During the cutting process, the I-shaped frame of the base 1 stably supports the weight of the profile, and the structural frame composed of fixed column 2 and sleeve 3 ensures that the support height remains unchanged, effectively avoiding problems such as profile swaying and sinking. The cutting accuracy is improved by about 30% compared with the traditional support method, and the cut flatness error is controlled within ±0.5mm.

[0045] Maintenance: After each shift, operators only need to wipe the surface of the device with a clean cloth to remove cutting debris and dust. Regularly (e.g., once a month) check the rotational flexibility of bearing 5. If any jamming is found during rotation, unscrew nut II10, remove the rotating mechanism, clean and lubricate bearing 5, and reinstall it to restore normal operation.

[0046] (II) Example 2: Application of Outdoor Temporary Processing Point

[0047] In some outdoor construction and emergency repair scenarios, temporary cutting work areas need to be set up. The portability of this material support rack is fully demonstrated.

[0048] Transportation and Portability: Since the components of the device use a detachable connection method (e.g., some connections are bolted, which can be disassembled before transportation), the material support frame can be disassembled into several main parts and placed in a dedicated toolbox. The toolbox is designed to be 600mm long, 400mm wide, and 200mm high for easy transport. Upon arrival at the site, assemble quickly according to the instructions. The entire assembly process takes no more than 15 minutes and requires no special tools; ordinary wrenches and screwdrivers are sufficient.

[0049] Cutting Adaptation: Assume a batch of 1m long, 30mm diameter steel pipes needs to be cut outdoors for scaffolding construction. After assembling the support frame, adjust handwheel 13 again according to the pipe diameter and cutting position to ensure the support height is just right. Place the steel pipes on the support frame. Due to the stable support of base 1 and the assistance of the rotating feed mechanism, the operator can easily push the pipes for cutting, increasing cutting efficiency by approximately 50% compared to manual cutting. Furthermore, the cutting process is safe and reliable, avoiding safety hazards caused by the pipes rolling or slipping.

[0050] Environmental Protection: Considering the complex outdoor environment, which may be affected by rain, dust, and other corrosive elements, if it is anticipated that the equipment may encounter rain during operation, it can be galvanized and passivated before assembly (if not pre-treated at the time of purchase) to ensure normal operation in humid environments. After use, wipe off moisture promptly and check all connections for looseness. If any are loose, tighten them immediately to prepare for the next use.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
