Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of feed oil cylinder, especially to a band saw machine structure with feed oil cylinder at the center of gravity of saw frame. BACKGROUND

[0002] The band saw machine structure with feed oil cylinder at the center of gravity of saw frame has unique advantages. This structure makes the band saw machine more stable during operation, effectively reduces vibration during sawing, improves sawing accuracy, and makes the movement of the saw frame more stable and smooth by placing the feed oil cylinder at the center of gravity of the saw frame, ensuring uniform distribution of sawing force. It optimizes the overall performance of the band saw machine, improves work efficiency, reduces error risks caused by vibration and instability, and makes the band saw machine more convenient to operate and easier to control sawing depth and speed, providing better user experience. It is widely used in metal processing and other fields to meet different sawing needs. The band saw machine structure with feed oil cylinder at the center of gravity of saw frame usually requires the following technologies:

[0003] 1. Ensure that the position of the feed oil cylinder can maintain good mechanical balance of the saw frame during work, reduce vibration and shaking, and improve sawing accuracy.

[0004] 2. Accurately control the movement of the feed oil cylinder to achieve stable feed speed and pressure to adapt to different material sawing needs.

[0005] 3. Design a strong and reasonable saw frame structure that can withstand various forces during sawing and provide a stable mounting position for the feed oil cylinder.

[0006] 4. Ensure that the transmission system of the band saw is efficient and stable, and coordinates with the action of the feed oil cylinder to improve sawing efficiency.

[0007] 5. Set necessary safety protection devices such as overload protection and emergency stop to ensure the safety of operators and equipment.

[0008] Currently, manufacturers use various equipment and methods to achieve the function of the band saw machine structure with feed oil cylinder at the center of gravity of saw frame. In terms of mechanical balance, through accurate calculation and design, the best installation position of the feed oil cylinder is determined to make the center of gravity of the saw frame as close as possible to the action point of the oil cylinder. In terms of oil cylinder control, advanced hydraulic control systems such as proportional valves and servo valves are used to achieve accurate control of the feed oil cylinder. In terms of saw frame design, high-strength steel or alloy materials are used to improve the rigidity and stability of the saw frame through reasonable structural design. In terms of transmission system, high-quality band saw blades and transmission components are used to ensure the reliability and accuracy of the transmission system. In terms of safety protection, various sensors and protection devices such as pressure sensors and travel switches are installed to detect and handle abnormal situations in a timely manner.

[0009] However, the above-mentioned mode has a prominent hardware structure problem. In the traditional band sawing machine structure, the feed oil cylinder cannot be located at the center of gravity of the saw frame due to the structural problem, which makes the saw frame unbalanced in force, cannot run smoothly and efficiently during sawing, affects the sawing efficiency, and at the same time, the poor stability of the work progress caused by the unbalanced force of the saw frame makes the saw frame easy to shake and deviate during sawing, affects the precision and produces safety hazards, and the unstable movement of the saw frame makes the saw blade unbalanced in force, accelerates the wear of the saw blade, increases the cost and reduces the production efficiency. In view of this problem, a solution is proposed, and a gantry type structure is designed. The structure is assembled by square tubes to form a gantry, and a linear guide rail is installed on the saw frame. The center of gravity of the saw frame is found by calculation, and the feed oil cylinder is installed. In this way, the stability of the work progress of the sawing machine can be effectively improved, and the wear of the saw blade is reduced. Content of the utility model
