What are the differences between domestic riveting machine and imported riveting machine?

At present, rivet machine products have been very popular in China, before we have talked about how to buy rivet machine, today we discuss whether to buy imported rivet machine or choose domestic rivet machine, now, I will only with my own experience, talk about this problem.

First of all, the first rivet machine appeared in the 1960s, and the first domestic rivet machine appeared in the 1970s in Wuhan Yangtze River (the former state-owned 733 factory), it should be said that the development process of the rivet machine domestic start is not much later than foreign rivet machine.

Domestic riveting machine and imported rivet machine how to choose Secondly, in terms of ordinary rivet machine, rivet machine imported and domestic rivet machine generation is poor, there is no technology was basically the same level, have the same structure, we know that imported rivet machine work and materials are good, this is the objective fact, but the price of homebred rivet machine is only one-third of JinKouJi, and substantial and durable, Service localization.

Therefore, the domestic market share of riveting machine is very high, more than 95%. For the international development trend of the rivet machine, riveting machine change in the past to learn from China, began to walk into the front desk, rivet machine domestic enterprises and development of heavy duty riveting machine and nc riveting machine, CNC spin riveting machine, rivet intelligent control system has been leading advantage, many Japanese, German companies are also in the procurement of domestic rivet machine, I am very confident predictions, In the future, the development of rivet machine technology will gradually be led by Chinese rivet machine enterprises, which is the inevitable result of the rise of China's industrial economy.

Cold roll riveting method of rotary riveting machine is a riveting method that uses riveting rod to pressure rivet locally and swing around the center continuously until rivet is formed. According to the cold rolling track of this riveting method, it can be divided into swing rolling riveting method and radial riveting method.

Swing roll riveting method is the riveting head of the workpiece first point contact side through the cylinder or hydraulic cylinder of the workpiece surface pressure and all-round rolling, so that the workpiece surface instantaneous deformation and riveting effect. Radial riveting, on the other hand, puts pressure on the central point and bends the metal around.

In terms of comparing the two riveting methods, Radial riveted on workpiece surface deformation when the demand is bigger than rolling type riveting pressure, at the same time its positive and negative sphere because of direct compression, so vulnerable, failure rate is high, after our many years of practice, this method has been gradually replaced by rolling type, and its machining quality not as good as rolling type appearance, its high failure rate at the same time, so the clients are now rolling type spiral Riveting machine.

In the process of riveting parts, the stability of rotary roller is good, the workpiece will not appear radial jitter, and affect the machining quality. Especially in circular arc riveting, when using rotary roll riveting, the workpiece basically does not need to touch the workpiece by hand, then the riveting work can be completed.

Routine maintenance of rotary riveter is as follows:

1, to be able to do, do not rivet beyond the nominal ability of the rivets;

2. The replacement riveting head shall be manufactured strictly in accordance with the specified length and shall not exceed or be lower than the specified length;

3. The maximum working pressure of pneumatic riveting machine shall not exceed 0.6mpa, and the maximum input oil pressure of hydraulic riveting machine shall not exceed 4MPa. Don't

Work under zero pressure or beyond zero pressure for a long time;

4. Adjustable body guide rail needs to be oiled on time to avoid rust;

5, very good riveting head pay attention to light pull and plug, too much force to make the internal structure of the riveting head assembly shift and then affect the riveting quality;

6, pay attention to adjusting the oil mist, usually every 4 days or so for circulating oil mist for a drop of oil;

7. Check the following primary parts on time: 1) Gradually check whether there is air leakage at each joint node from the intake breath; 2) look at the forming part of the riveting head (that is, the cavity of the riveting head) whether there is a binding tumor, and tidy it; 3) Check whether the lubricating oil in the oil mist is sufficient (it is 1/2 the height of the oil can).

8. It is best to protect all the equipment once every six months to ensure that the sealing ring and electrical equipment are in the best condition.
