Description

Improved Structure of Machining Tool

technical field

The utility model relates to a processing tool, in particular to a drill bit and a milling cutter.

Background technique

Under the trend of electronic products becoming lighter, thinner, shorter and smaller, the size of various electronic products is also gradually reduced, and the manufacturing and processing processes of various parts inside electronic products are relatively more and more refined. And all kinds of electronic products must have printed circuit boards for setting the printed circuit boards of electronic parts groups. The volume of the printed circuit boards must also be reduced with the volume of electronic products. , usually use micro-processing tools to drill or cut on the circuit board to connect the inner circuit of the circuit board. However, the existing processing tool material uses tungsten carbide as the material of the processing tool, and tungsten carbide is integrated Although the processing tool has good rigidity and hardness and long service life, the cost is too high, and the processing tool is a consumable material, which will increase the economic cost of manufacturing.

Another industry uses the combination of cutting tools, so that the stainless steel handle and tungsten carbide are combined by welding or high-frequency heating method to make a round bar, and then processed into a processing tool, but because the connecting surface is directly cut by the machine. Smooth, the machining tool cannot be reliably joined when welding or high-frequency heating is used, so that the degree of bonding is greatly reduced, and in the production process, because the contact area of the connecting surface is too small, it is easy to cause damage or fracture of the machining tool.

As shown in Figure 7, it is an exploded plan view of the combination of existing knives, which includes a handle A and a butt end A1 provided at one end thereof, and is provided with a blade B relative to the butt end A1, and one end of the blade B In order to provide a connection end B1, and to use the connection end B1 and the butt end A1 to join, because the combination is to use welding or high-frequency heating method, and the connection end B1 and the butt end A1 are both smooth planes, only the During joining, a connection effect occurs on the outer edge of the connection end B1 and the mating end A1, and a reliable connection cannot be made.

The combination of the above-mentioned existing cutting tools still has many deficiencies to be improved during actual use, such as:

(1) The combination of the cutter is to utilize the butt end A1 of the handle A, and the connection end B1 of the blade B is a combination of two planes, and the joint surface area of the butt end A1 and the connection end B1 is relatively small during processing and combination , resulting in insufficient structural strength after the tool is combined, and because the tool is fixed on the machine and used, when the tool is removed and used for extraction with hand tools, it will be damaged by the force of external force or the accumulated stress under long-term use. Make the combination of the tool loose or break.

(2) After the tool handle A and blade B are combined and processed, due to the poor welding strength between the butt end A1 and the connection end B1, when the machine is running at high speed, it is easy to form cracks at the joint, which affects the quality and safety of the tool.

Therefore, how to solve the problems and deficiencies in the combination of existing cutting tools is the direction that relevant manufacturers engaged in this industry are eager to study and improve.
