Abstract
The utility model relates to a special cutter for a galvanized iron-soldered tungsten steel type PCB (printed circuit board), which comprises a galvanized iron handle part, a tungsten steel head material and a cutter head. The galvanized iron handle part is connected with the tungsten steel head material through a silver soldering terminal. The special cutter for the galvanized iron-soldered tungsten steel type PCB uses the silver soldering terminal which is heated to the temperature of 290-310 DEG C through a soldering machine, the performance of tungsten steel is unchanged, and meanwhile, the aim of effectively saving the tungsten steel is achieved, the production cost of factories is lowered, and the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of cutter, particularly a kind of galvanized iron welding wolfram steel type pcb board dedicated tool.
Background technology
For a long time, the pcb board dedicated tool can only be the precision cutting tool that full wolfram steel is produced, and unalterable production and the use of this mode exists this maximum drawback of waste rare metal (wolfram steel).
Summary of the invention
Technical problem to be solved in the utility model provides a kind of galvanized iron welding wolfram steel type pcb board dedicated tool, and the shank of the pcb board dedicated tool of full wolfram steel in the former production technology is alternative with galvanized iron, economizes on resources to greatest extent, improves traditional mode of production.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of galvanized iron welding wolfram steel type pcb board dedicated tool, comprise the galvanized iron shank, and wolfram steel head material, cutter head, the galvanized iron shank is connected by the silver soldering sheet with wolfram steel head material.
The silver soldering temperature of described connection galvanized iron shank and wolfram steel head material is 290 ℃-310 ℃.
A kind of galvanized iron welding of the utility model device wolfram steel type pcb board dedicated tool is by the silver soldering sheet, use welding machine to heat to 290 ℃-310 ℃, the performance that does not change wolfram steel has reached the purpose of efficient economizing wolfram steel simultaneously, has reduced the production cost of factory, enhances productivity.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structure drawing of device.
The specific embodiment
A kind of galvanized iron welding wolfram steel type pcb board dedicated tool comprises galvanized iron shank 1, wolfram steel head material 2, and cutter head 3, galvanized iron shank 1 and wolfram steel head material 2 are connected by the silver soldering sheet.The silver soldering temperature of described connection galvanized iron shank 1 and wolfram steel head material 2 is 290 ℃-310 ℃.
The utility model device substitutes the shank of the pcb board dedicated tool of full wolfram steel in the former production technology with galvanized iron, that is: the total length of cutter is 38.30 ± 0.05mm, wolfram steel head material 2 sizes have following several respectively: 14.40mm, 13.5mm, 12.5mm etc., galvanized iron shank 1 corresponding size has following several: 24.0mm, 24.9mm, 25.9mm etc., saved most wolfram steel.
