Description

Technical Field

[0001] This invention relates to a nut, specifically a lightweight stamped drum-shaped nut. Background Technology

[0002] With the development of modern industry, automobiles have become an indispensable means of transportation in people's daily lives. In the automobile manufacturing process, the selection of materials for parts is particularly important, and with continuous technological advancements, plastic parts have gradually replaced sheet metal parts, becoming the preferred choice for many automakers.

[0003] Existing nuts used for connecting sheet metal and plastic parts in automobiles are mostly standard parts or old-fashioned plate nuts, which are tightened and fixed by a fastening gun. The large number of these parts increases the overall weight of the machine, hindering current energy-saving and lightweight design principles; moreover, plate nuts have poor tightening performance and are prone to failure during use. Summary of the Invention

[0004] The purpose of this invention is to overcome at least one of the defects of the prior art and provide a lightweight stamped drum nut.

[0005] In this invention, the drum-shaped nut is integrally formed. It is made of cold-rolled spring steel material and stamped by a mold. Then, the part is heat-treated to increase its strength and rigidity. Finally, it is surface-treated (Dacromet / galvanized) to ensure corrosion resistance and aesthetics.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A lightweight stamped drum-shaped nut, comprising:

[0008] The nut body has a threaded hole in its middle and multiple weight-reducing holes along its circumference;

[0009] The positioning claw, which has the function of assembling tool slot, is set on the side of the weight reduction hole away from the threaded hole and extends towards the bulging end of the nut body.

[0010] Anti-slip protrusions are set on the clamping surface of the nut body.

[0011] Furthermore, positioning blocks are provided around the periphery of the nut body.

[0012] Furthermore, the positioning blocks are evenly distributed around the nut body in the circumferential direction.

[0013] Furthermore, there are at least two positioning blocks, preferably two.

[0014] Furthermore, the clamping surface of the nut body along the circumferential direction is provided with anti-slip protrusions, which can prevent slippage during the tightening process.

[0015] Further, the anti-skid protrusions are at least two, preferably two.

[0016] Further, the weight-reducing holes are at least six, preferably six.

[0017] Further, the positioning claws are at least six, preferably six.

[0018] Further, the positioning claws gradually narrow in width during the outward extension, and the positioning claws can ensure the positioning between the nut and the nut clamping piece.

[0019] Further, the nut surface is plated with a 12-25um corrosion-resistant film, preferably a Dacromet or galvanized film.

[0020] Compared with the prior art, the present application has the following advantages:

[0021] (1) The stamping drum nut designed in the present application is light in weight through the weight-reducing holes, and provides a certain anti-loosening force through the pressing surface of the nut extruded by the screw screwed in subsequently, and avoids slipping during fastening through the anti-skid protrusions.

[0022] (2) The stamping drum nut designed in the present application is integrally formed under die stamping, and has light part weight and high nut strength.

[0023] (4) The stamping drum nut designed in the present application is produced by a continuous die, and has high product size and precision, high product qualification rate, good consistency and stability, good interchangeability, and can meet the assembly and use requirements without further mechanical processing.

[0024] (5) The stamping drum nut designed in the present application is produced by a die, and has high production efficiency and simple operation, is easy to form mechanized production, liberates labor, is light in weight and low in energy consumption compared with traditional nuts, greatly improves production capacity, and reduces cost

[0025] (6) The stamping drum nut designed in the present application has low cost, simple structure, and high overall strength.

[0026] (7) The stamping drum nut designed in the present application can be adjusted according to actual environment, and increases its applicability and universality.

[0027] (8) The stamping drum nut designed in the present application has the advantages of light weight, good rigidity, and outstanding consistency compared with traditional types of lock nuts, and is widely used in the automobile (home appliance) industry. BRIEF DESCRIPTION OF DRAWINGS
