Description

Technical Field

[0001] The present invention relates to a segment cutting device for radiator production, belonging to the technical field of machining and manufacturing equipment. Background Art

[0002] Currently, in the production of radiator equipment, due to a large number of pipe and plate cutting operations involved, and these pipes and plates often have a small equipment thickness, large length and area, and relatively weak structural strength. To address this problem, currently, mainly traditional sawing machines and other equipment are still used for cutting. Although it can meet the usage requirements, it requires operators to perform frequent workpiece loading and positioning, and disassembly operations. As a result, on the one hand, the work efficiency of raw material and blank clamping, positioning, and disassembly operations during cutting is low, and the labor intensity is high. At the same time, it is also difficult to clamp and position the raw materials, and the positioning stability is poor. Moreover, during operations such as clamping, positioning, cutting, and disassembly, it is easy to cause structural damage to the materials or the cut blanks, thus affecting the production efficiency and accuracy of radiator equipment processing operations.

[0003] Therefore, to address this problem, it is necessary to develop a new segment cutting device for radiator production to meet the actual work requirements. Summary of the Invention

At the same time, during the assembly, synchronously set the number of arc positioning seats and the type of positioning fixture structure provided inside the arc positioning seats; S2. Workpiece clamping: During the cutting operation, first, through the flipping mechanism, adjust the flipping frames of the guide plate and the arc positioning seat to flip and be located at the lowest point position. Then, preliminarily position the raw material to be cut through the positioning fixture connected to the flipping frame. Then, drive the flipping frames of the guide plate and the arc positioning seat to flip to the working state through the flipping structure, so that the flipping frame and the fixed frame form a cylindrical frame structure, and the positioning fixture connected to the fixed frame performs secondary strengthening clamping and positioning on the raw material to be cut; S3.

Finally, after completing the cutting operation, the guide plate and the turning frame of the arc positioning seat are adjusted by the turning mechanism to turn and be located at the lowest point position, and then the positioning fixture connected to the turning frame releases the clamping and positioning of the cut blank, so that the blank slides down along the guide plate to the lowest point under its own gravity and is collected by the staff, thus completing the cutting operation.
