The development and application of servo-electric tapping machine

The development and application of servo-electric tapping machine.

1.1 Principle of tapping machine: 

The drilling of the drilling and tapping machine is to use a twist drill bit to process the hole in the material, and this cutting method is called drilling. In the field processing of large workpieces, drilling is the most widely used processing technology. For example, there are 50-60 large holes of 30-130mm distributed on large equipment. Due to the different uses of these holes, they often need to go through various processes such as drilling, reaming, boring, and tapping. In order to ensure the position accuracy of the hole, the drilling should have a preparation process - the pressing and punching process. The sample punch is used to press out the sample punching pit at the position where the workpiece surface needs to be drilled, so that the drill bit can be guided during drilling to avoid the deflection of the drilling. Then move the drilling and tapping machine to drill, ream, boring and tapping one by one, so the design of drilling and tapping must be light and easy to move.

The tapping of the drilling and tapping machine is to use the national standard machine to tap on the bottom hole that has been drilled, and the distribution on the large equipment is very uneven, some on the plane, some on the side, and some on the top. Therefore, the drilling and tapping rig is required to be rigid, strong and lightweight, and easy to move. The largest threaded hole on a large machine is M130, and the drilling and tapping rig must have the ability to process large threaded holes. Machine tap refers to the high-speed steel grinding tap, which is suitable for tapping on the machine tool, and the drilling and tapping machine must have the ability to use the national standard machine tap to reduce the cost of use.

In addition to the ability of drilling and tapping, the drilling and tapping machine should also have the ability of reaming and boring to meet the customer's requirements for various hole processing processes.

1.2 Classification of tapping machines

According to the different driving power sources, the knuckle arm tapping machine can be divided into hydraulic tapping machine, electric tapping machine, pneumatic tapping machine;

According to the number of tapping machine spindles, it can be divided into single-axis tapping machine, two-axis tapping machine, four-axis tapping machine, six-axis tapping machine, multi-axis tapping machine, etc.;

According to the different types of processed parts, the tapping machine can be divided into in-mold tapping machine, universal tapping machine, hot nut tapping machine, flange nut tapping machine, round nut tapping machine, hexagon nut tapping machine, blind hole nut tapping machine, anti-theft nut tapping machine and other models;

According to the different degree of automation of the tapping machine, the tapping machine can be divided into automatic tapping machine, semi-automatic tapping machine and manual tapping machine, CNC tapping machine, etc.;

According to whether the tapping machine is drilling at the same time when tapping, the tapping machine is divided into drilling and tapping machine, reaming tapping machine, special tapping machine, CNC tapping machine, and universal boom tapping machine.

The automatic tapping machine has the highest degree of automation, when working, as long as the parts blank is put into the hopper, it can be automatically fed, automatic positioning, automatic clamping, automatic tapping, automatic unloading, a worker can operate multiple equipment at the same time, high production efficiency, can significantly save labor costs! The high-quality tapping machine has the characteristics of novel design, reasonable structure, simple and easy to use, high degree of automation, easy to use, high efficiency, maintenance-free, cost-effective, etc., and the high-quality nut tapping machine has high thread finish and high pass rate of finished products.

Fields of application

Since the tapping machine was introduced to the market, it has been deeply cared for by users for its lightweight, flexible, efficient and irreplaceable advantages with other similar equipment. It avoids the limitations of lathes, drilling machines or manual tapping, and saves time, labor, is not easy to rot teeth, and taps are not easy to break, etc., and its remarkable characteristics are widely praised and adopted by users. This machine is suitable for all machinery manufacturing industries, and the mainland customers cover machine tools, mold (factory) machinery, plastic machinery, printing machinery, packaging machinery manufacturing plants, construction machinery, automobile and motorcycle parts, aero engines, rolling stock, tobacco machinery and general machinery and other industries
