What are the basic safety requirements for mechanical equipment operators?

2021-10-19

To ensure that mechanical equipment does not have work-related accidents, not only the mechanical equipment itself must meet the safety requirements, but more importantly, the operator is required to strictly abide by the safety operation procedures. Of course, the safety operation procedures of mechanical equipment vary according to their types, but their basic safety requirements are: (1) must correctly wear moth good personal protective equipment. The dragon must wear fried. Don't wear anything you shouldn't wear. For example, when machining, female workers are required to protect their handbags. If they do not wear them, they may twist their hair in. At the same time, no gloves are required, if so. The rotating part of the machine may tattooed the glove and wring the hand. (2)

Maintenance process of spot welding machine

2021-10-19

The medium frequency DC spot welding machine shall be provided with reliable grounding protection. The parallel installation distance of multiple equipment shall not be less than 3m. Inspection shall be carried out before operation. The pressure mechanism of the welding machine shall be flexible, the fixture shall be firm, and the gas-liquid system shall be free of leakage. medium frequency dc spot welding machine Before welding, the corresponding parameters and secondary voltage should be adjusted according to the workpiece to be welded, the cooling water should be discharged regularly, the contact points and electrodes of the circuit breaker should be polished, and all connecting bolts of the secondary circuit should be tightened regularly. Regularly inject lubricating oil into the rotating conductive part. The maintenance of the welding arm and electrode lies in that the welding arm and electrode will pass a large current when working. If a thicker oxide layer accumulates on the surface, it will cause electricity.

Do you need a skilled operator to operate a medium frequency spot welder?

2021-10-19

Before welding, the appropriate welding conditions are mainly found at the beginning, and the appropriate parameters are adjusted according to the welded workpiece. The control device (I. e. controller) will weld according to the set conditions. In order to find good welding conditions, people who are familiar with welding technology are required. However, after the good welding conditions are set, even workers without operation experience can operate. However, there is one thing worthy of our attention and learning: in the process of operation, the surface of the electrode will form white medium on its surface with the increase of welding times. if there is no timely grinding, the resistance will increase and the shadow will increase.

What is the function of the transformer of the intermediate frequency spot welding machine

2021-10-19

First of all, a high-quality intermediate frequency spot welding machine, its transformer must first be wound with copper enameled wire at the primary level, and the secondary level is an integrated water-cooled structure poured with copper. High-quality oxygen-free copper structure, good effect, low resistivity, high conductivity, slow oxidation rate, long service life, in recent years, more and more vacuum casting transformers, which has become a trend, because the vacuum casting transformer moisture insulation effect is good, longer service life.

What packaging is generally used for butt welding machines

2021-10-19

The packaging used by the butt welding machine belongs to the mechanical category, which is relatively large in volume and heavy in weight. The requirements for packaging are also very strict. Generally, solid wooden boxes are used for packaging, while plywood wooden boxes that meet international standards are required for export.

How many welding methods are there?

2021-10-19

There are many ways to weld metals. How to find the most suitable welding method for you? I believe everyone is very smart. They will consider the cost, efficiency, product quality, quality of welded products, mechanical life, environmental protection and other aspects. These small series will not be written in detail for the time being. Let's talk about the basic methods first. 1. from the broad category, there are three methods namely 1. Pressure welding 2. Fusion welding 3. Brazing 1) Pressure welding is subdivided: ① Resistance butt welding Resistance spot welding, projection welding and seam welding ③ Cold welding ④ Ultrasonic welding ⑤ Explosive welding

Maintenance of Medium Frequency Spot Welding Transformer

2021-10-19

1. Primary ground insulation inspection Requirements for primary ground insulation inspection 1. Tools: 1000v shaking table 2. Measurement method: First, remove the incoming wire of the primary transformer, clamp one of the two pens of the shaking table at the terminal of the primary incoming wire of the transformer, and clamp the other on the screw fixing the transformer. Shake 3 to 4 turns to observe the change in the block. If there is no group size, it proves that the transformer is well insulated to the ground. If the resistance is less than 2 megohms should be abandoned. And notify the maintenance. 2. Inspection of secondary rectifier diode Check the secondary rectifier diode is relatively simple, with a digital multimeter

Transformer Function of Medium Frequency Spot Welding Machine

2021-10-19

For a medium frequency spot welding machine with excellent quality, its transformer must first be wound with copper enameled wire at the primary level, and the integrated water-cooled structure with copper pouring at the secondary level. High-quality oxygen-free copper structure, the best effect, low resistivity, high conductivity, slow oxidation rate, long service life, in recent years, more and more vacuum casting transformers, which has become a trend, because the vacuum casting transformer moisture insulation effect is good, longer service life. However, due to the result of vicious market competition, some enterprises now upgrade the primary and secondary transformers to aluminum transformers in order to reduce production and manufacturing costs, which greatly reduces the manufacturing cost.

Production Method of Medium Frequency Water-cooled Transformer

2021-10-19

In recent years, with the car into the ordinary family, car production and sales gradually increased. With the needs of automobile production and the progress of science and technology, a variety of welding methods continue to emerge, and there have been more than 20 kinds of welding methods, such as gas shielded welding method, cold pressure welding method, resistance welding method, ultrasonic welding method, and the more commonly used welding methods are generally resistance welding method and gas shielded welding method. At present, the traditional resistance spot welding machine is composed of three parts: power supply and control device (welding controller), energy conversion device (welding transformer) and welding actuator
