Equipment used for machining three-dimensional externally finned tubes

Abstract

The invention discloses equipment used for machining three-dimensional externally finned tubes. The equipment used for machining the three-dimensional externally finned tubes comprises a rack, a cutter and a workpiece feeding device. The cutter comprises cutter bodies, an upper die and a lower die. The cutter bodies are longitudinally inlaid in the upper die. Cone-shaped sleeves are longitudinally inlaid in the lower die. Each cutter body comprises a cutter rest and a group of cutter teeth. Each group of the cutter teeth are radially arranged at the end of the corresponding cutter rest evenly, and space is reserved between every two cutter teeth. Each cutter tooth comprises a cutter blade portion and a cutter point portion. The cutter blade portions are connected with the cutter rests. Included angles are arranged between the cutter point portions and the cutter blade portions, and the cutter point portions are close to the axes of the cutter rests. The cutter point portions are close to the large diameter sides of the cone-shaped sleeves in the lower die. The cutter rests are far away from the large diameter sides of the cone-shaped sleeves. According to the equipment, the defects that the uniformity of the depths, angles and thicknesses of fins cut through a cutter of existing equipment used for machining three-dimensional externally finned tubes are low and the strength and heat dissipation effect of the tubes are lowered are overcome. The equipment used for machining the three-dimensional externally finned tubes comprises the cutter, and the uniformity of the depths, angles and thicknesses of the fins cut through the cutter are high.

Description

technical field [0001] The invention belongs to the field of turning devices, and in particular relates to a device for processing three-dimensional outer ribbed tubes. Background technique [0002] The three-dimensional outer rib tube is to cut three-dimensional fins on the outer wall of the tube, so as to improve the heat dissipation function. Existing three-dimensional externally ribbed tubes are usually fins arranged in an axial line. When processing the outer fins, the cutter teeth are inserted into the outer wall of the tube, and then pushed forward, the three-dimensional fins can be cut out on the outer wall of the tube, and then retreated to reset, repeating the previous action, while the tube itself moves forward, so that the outer wall of the tube Cut out the outer fins that line up neatly along the axial line. [0003] Chinese patent, the notification number is: CN203037126U, in order to strengthen the heat dissipation performance of the outer rib tube, the fins...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing cutting tool used for processing three-dimensional outer ribbed pipe equipment adopts the ring gear to shrink and cut out the fins, and the depth, angle and thickness of the cut out fins are poor in consistency, thereby reducing the strength and Heat dissipation effect, providing a cutting tool with high consistency of fin depth, angle and thickness to avoid affecting the strength and heat dissipation effect of the workpiece for processing three-dimensional outer rib tube equipment
