Cutting tool for machining fin of automobile radiator

Abstract

The invention relates to a cutting tool for machining a fin of an automobile radiator. The cutter comprises a cutter shaft and a plurality of blade units arranged in the axial direction of the cuttershaft, wherein each blade unit comprises a left rotary cutter, a right rotary cutter, a folding piece arranged between the left rotary cutter and the right rotary cutter and an interval piece arrangedat the other end of the left rotary cutter and the other end of the right rotary cutter, and each of the left rotary cutter and the right rotary cutter comprises a plurality of saw-shaped cutter teeth which are arranged in order. According to the cutting tool for machining the fin of the automobile radiator, compared with the prior art, due to the fact that the cutting edge length, the thickness,the angle and the blade arrangement of the saw-shaped cutter teeth is changed, the window opening length and angle of the fin are changed, the wind resistance of the radiator is reduced, the coolingefficiency of the fin is improved, and thus the heat dissipation performance of the radiator is improved.

Description

technical field [0001] The invention relates to the technical field of automobile radiators, in particular to a cutter for processing the fins of automobile radiators. Background technique [0002] The car radiator is composed of three parts: the water inlet chamber, the water outlet chamber and the radiator core. Coolant flows inside the radiator core and air passes outside the radiator. The hot coolant cools by dissipating heat to the air, and the cold air heats up by absorbing heat from the coolant. However, since the area of ​​the automobile radiator cannot be too large, how to improve the heat dissipation efficiency in the limited fin area is of great significance for improving the heat dissipation performance of the automobile radiator. The performance of the existing radiator is about 15% different from the heat dissipation performance index required by the customer, which is far from meeting the customer's demand. [0003] In addition, due to the different models,...

The performance of the existing radiator is about 15% different from the heat dissipation performance index required by the customer, which is far from meeting the customer's needs

[0003] In addition, due to the different models, the width of the fin strips is also different. The current production process can only produce fin strips with two length specifications, which cannot meet customer requirements.
