Summary of information:We have more than ten years of production experience in the screw industry, the main products are: multi-functional one-...

The composition and proportion of this high-performance stainless steel screw thread are: 0.08%-0.15% C; 0.01%-0.60% Si; 0.02%-0.60% Mn; 0.01%-0.03% P; 0.002%- 0.03% S; 12%-14% Cr; 0.8%-1.5% Mo and the rest is Fe. The preparation method includes the following steps: smelting molten steel according to chemical composition requirements; hot rolling; annealing and pickling to obtain a stainless steel plate blank; coating and drying; cold drawing; cleaning and drying with a neutral activator; quenching; tempering ; coated and dried; drawn into stainless steel thread. This high-performance stainless steel screw line is energy-saving and environmentally friendly, with high corrosion resistance, high elasticity and high toughness. The preparation method and process are advanced and simple, and the production cost is low.

As the preferred embodiment of the above-mentioned embodiment, the motor 41 is provided with a thruster 46 that moves the cutting wheel 42 toward the conveying device 3. When the screw needs to be slotted, the thruster 46 generates a thrust toward the screw, and the motor 41 generates a thrust in the direction of the screw. Under the action, the groove is moved along the track 47 toward the screw. The other end of the motor 41 is provided with a bearing 45, and the output end of the motor is provided with a special-shaped wheel 44. The special-shaped wheel 44 is geared to the bearing 45. The wheel 42 is close to or away from the conveying device 3. When the grooving is completed, the special-shaped wheel 44 rotates and drives the bearing 45 to generate the opposite force from the above-mentioned thrust, so that the motor 41 moves back to the original position along the track 52.

Screws are a kind of fasteners commonly used in machinery, but most of the screws commonly used in the market are standard parts. The screws themselves are ordinary and have no function of preventing loosening and protecting the matrix. Therefore, in order to prevent the screws from loosening during use , Usually it is necessary to configure additional elastic washers, flat washers, etc. that are suitable for screws, and these elastic washers and flat washers are mostly metal products. During use, it is easy to wear with the body base and damage the protection of the sheet metal base. After long-term use, metal washers are easy to rust, which affects the tightening effect and appearance of screws. In addition, the use of metal washers not only increases the weight and cost, but also the assembly process is complicated and cumbersome, and the anti-loosening and anti-wear effects are not ideal. .

Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of locking nut, which includes a nut, the bottom of which is circular, the middle is hexagonal, the top is circular, there is a bolt hole in the center, the side wall of the bolt hole is threaded, and the top of the nut is Set up several squash notches. According to the locking nut of the preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the number of flattening notches is three. The three flattening gaps can be used as the focal point of the tightening tool and the clamping place of the anti-loose gasket bayonet, and the structure is simple and can be formed by die stamping at one time.

At present, the known automatic nail feeding screws are composed of the traditional hand-held electric drill modified electric screw and the automatic nail feeding device, in which the screw head cannot be moved and the angle can be changed. It is difficult to complete the installation due to the obstruction, so a multi-directional screw with a movable and rotatable screw head is required.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: external tongue washers, quick-release joints FKM gaskets, corrosion resistance, cross recessed round head screws, cabinet case nuts and other products, we can provide you with suitable products. Your fastener solution.
