An air conditioner fin die with fast switching of point cutting and longitudinal cutting number

Abstract

The present invention discloses an air conditioner fin mold capable of quickly switching between spot cutting and longitudinal cutting rows. The mold comprises an upper mold plate and a lower mold plate, with longitudinal cutting devices and spot cutting devices arranged side by side in the front-to-back direction between the upper and lower mold plates. Compared with the prior art, the present invention provides separate longitudinal cutting and spot cutting devices. Therefore, when producing fins with different spot cutting rows, there is no need to remove and replace the blades. The mold's operating state can be quickly switched using the spot cutting and longitudinal cutting adjustment plates, significantly reducing the debugging work after mold disassembly and assembly, saving labor time, and preventing damage caused by disassembly due to changing the number of fin rows.

Description

Technical Field

[0001] The invention relates to the field of moulds, and in particular to an air-conditioning fin mould capable of quickly switching the number of point cutting and longitudinal cutting rows. Background Art

[0002] In the existing longitudinal cutting structure of the air conditioner fin mold, the row number of fins is changed by controlling the cutting depth of the upper and lower cutters. Manufacturers often need 2 or more rows of fins when producing, and the middle of each row needs to be cut without being cut off (hereinafter referred to as the virtual cutting state). At present, the mature solution is to modify the row cutter in the position where cutting without being cut off, and add a small notch in the middle of the blade, commonly known as the virtual cutter, such as Figure 1 As shown in the figure, the fins cut in this way will have a continuous state of "cut-connect-cut-connect" in the middle.

[0003] However, the above solution brings another problem while achieving virtual cutting. Figure 2 As shown in the figure, it is a schematic diagram of the production structure of two rows of fins. Figure 3 The figure shows a schematic diagram of the production structure of 3 rows of fins. When switching from 2 rows of fins to 3 rows of fins, some of the positions that originally needed to be virtual cut need to be changed to a cut state, and the positions that were originally cut need to be changed to a virtual cut state. In this way, it is necessary to disassemble these blades and replace them with the required blade types. If a 60-row mold is used to convert the number of rows from point cutting to longitudinal cutting, it will be necessary to disassemble and change the blades more than 10 times for each switch. After changing the blades, the clearance between the upper and lower blades must be debugged to prevent abnormalities such as fin cutting or burrs. The conversion takes at least 2 hours. At the same time, the skills of the on-site conversion personnel are very high. Ordinary personnel may spend half a day on conversion and debugging, which greatly affects production efficiency. Therefore, it is urgent to solve this problem. Summary of the Invention
