Beauty people often put such a sentence on the lips: fire prevention, anti-theft, anti-colored wolf, this is the three defense requirements of the majority of beauty. As the "beauty" of our production workshop - CNC cutting machine, there are also "three defenses." Xiaobian will explain to you about the “three defenses†knowledge of CNC cutting machine: Extrustion Blow Molding Machine Blow moulding machines can be divided into three categories: extrusion blow moulding machines, injection blow moulding machines and special structure blow moulding machines. Stretch blow molding machines can be classified into each of the above categories. Extrusion Blow Molding Machine is the combination of extruder, blow molding machine and die closing mechanism, which is composed of extruder and blank die head, blow expansion device, die closing mechanism, blank thickness control system and transmission mechanism. The blank die is one of the important components that determine the quality of blow molding products, usually including the side feed die and the center feed die. The storage cylinder type blank die head is often used for large products during blow molding. The minimum volume of the storage tank is 1kg and the maximum volume is 240kg. The parison thickness control device is used to control the parison wall thickness. The maximum control point is 128 points, generally 20~30 points. The extrusion blow molding machine can produce hollow products with a volume range of 2.5ml~104l.

One of the three defenses: to prevent damage As the CNC cutting machine is a relatively sophisticated numerical control equipment, so whether it is in the process of handling or moving, we must pay special attention to prevent damage, the specific requirements are as follows:
1. When the cutting machine is running, you should pay attention to whether there are people or other objects in front of it so as to avoid hitting.
2. After each cutting is completed, the torch should be raised to the highest position so as not to hit the steel plate and damage the cutting torch.
3, mechanical maintenance personnel in the maintenance should ensure that the machine is stopped working. And hang up warning signs to prevent the sudden operation of the machine and human accidents.
The third defense: the fire prevention Because the CNC cutting machine will use the corresponding gas during the operation, such as: acetylene, propane, liquefied gas and other gases, some of these gases are flammable, of course, there are other factors, the specific requirements are as follows :
1. The working materials used by the cutting machine are flammable gases such as acetylene, propane, liquefied gas and other gases. Therefore, it is necessary to periodically check whether the entire air path is sealed.
2. During the flame cutting, it must be ensured that flammable substances are not allowed to appear within the splash range of the slag.
3. Inspect the circuit of the CNC cutting machine to prevent the fire caused by the aging of the line.
Three defenses: The specific requirements for preventing electric shock and preventing electric shock are as follows:
1. When checking the circuit or replacing electronic components, please disconnect the power supply to prevent accidents.
2. Do not touch the power distribution cabinet or the console during the operation of the machine. Otherwise, there is a risk of electric shock.
3. Do not operate any switch knob wetly to prevent electric shock.

Injection blow molding machine is the combination of Injection Molding Machine and blow molding mechanism, including plasticizing mechanism, hydraulic system, control electrical apparatus and other mechanical components. Common types include three-station injection blow molding machine and four-station injection blow molding machine. The three-station machine has three stations for preforming, blowing and demoulding, each of which is separated by 120 °. The four-station machine has more pre-forming stations, each of which is separated by 90 °. In addition, there is a dual-station injection blow molding machine with 180 ° between stations. The plastic containers produced by the injection blow molding machine are accurate in size and do not need secondary processing, but the mold cost is high.
The special structure blow molding machine is a blow molding machine that uses sheet, molten material and cold blank as parison to blow mold hollow body with special shape and purpose. Due to the different shapes and requirements of the products produced, the structure of the blow molding machine is also different.
