Every year, the scale of construction in Russia is gaining more and more momentum, respectively, the demand for special equipment and materials is also growing. With the development of technology, devices producing building materials are also being improved. One of such devices is equipment for the production of self-tapping screws, which we will talk about today.
Device
It should be noted that regardless of the scale of production, the technology for manufacturing such hardware (metal products) remains unchanged. Thus, each equipment for the production of self-tapping screws includes the following devices:
- Cold-upsetting machine, which forms the configuration of products.
- Quenching furnace, performing the function of removing the surface tension of the metal.
- Thread rolling workbench. It performs the specified metric profile of the device.
- A centrifuge designed for drying finished products using heated air.
- Electroplating line. Often it consists of 5-10 bathtubs, standing in parallel to prepare the surface of the screws and apply additional protection to them.
How does the equipment for the production of self-tapping screws work?
The principle of operation of this device, despite the special formation of finished products, practically does not differ from that used for the production of nails. At the first stage, a wire of a certain diameter is fed into the cutting machine. Its width will determine the further dimensions of the product. Getting into the same machine, the wire is cut into pieces, after which the self-tapping head is planted on the same device. At the next stage, the product is fed to another machine, but already for threading. In this case, the length of the future self-tapping screw is determined before it is fed to this unit. Further, the product goes through a heat treatment stage, and is placed in a special quenching furnace. At the final stage, the tool is washed and anti-corrosion treatment. The output is a finished screw or screw, depending on the equipment used. However, it is worth noting that if you want to produce a high-quality product, your equipment for the production of self-tapping screws must be understaffed with additional tools, a complete list of which we noted in the previous subheading.
Manufacturers
The main machines used in the production of such tools are the devices of the Taiwanese company LianTeng and FOB, as well as the Chinese devices INNOR and Candid. Their products are considered the most high-quality and high-tech in the world market.
How much does a machine for manufacturing self-tapping screws cost?
The price of this device is determined by its performance. So, for example, devices that issue about 50 units of screws per minute cost from 70 thousand rubles. More powerful units with a capacity of up to 250 units / min cost about 200 thousand rubles or more. For the production of self-tapping screws, equipment whose price is less than 50,000 rubles (these are usually used options) is better not to allow, since there are a lot of problems with these units during operation.
