TW201628831A - Non-slip manufacturing process for metal grip of hand tool - Google Patents

Abstract

The invention relates to a non-slip manufacturing process for a metal grip of a hand tool and, more particularly, to a process characterized in using stamping or roll molding to form a plurality of non-slip parts with decorative patterns, convex dots or concave dots on a cambered surface or curved surface of the metal grip of the hand tool along an axial direction of the metal grip of the hand tool, so as to improve a non-slip effect of gripping and provide an excellent grip feeling. The non-slip manufacturing process for the metal grip of the hand tool includes: using two upper and lower stamping molds to form one or plural surfaces of non-slip parts on the cambered surface or curved surface of the metal grip of the hand tool by stamping, wherein the two upper and lower stamping molds are provided with two upper and lower stamping cavities and two upper and lower stamping patterns.

Description

Hand tool metal grip anti-slip process

The anti-slip process of the metal grip of the hand tool of the invention is mainly applied to the technique of increasing the anti-slip effect and the excellent grip feeling of the metal grip of the hand tool.

According to the traditional hand tool metal grip, in order to increase the anti-slip effect when holding, the following methods are included in the implementation: Please refer to the first figure: a schematic plan view of the first type. The hand tool metal grip 10 of the first type is mainly provided with a grid-like embossing 11 on a flat surface, and the hand tool metal grip 10 of the first type can only be applied to a flat surface, and the scope of application is applicable. The narrower shape not only limits the shape of the metal grip 10 of the hand tool, but also affects the grip when holding.

Please refer to the second figure: a schematic plan view of the second formula. The hand tool metal grip 20 of the second type is mainly provided with two annular grooves 21 in front of the circular arc surface, and three annular grooves 21 at the rear, and between the annular grooves 21 The grid-shaped embossing 22 is provided on the flat surface, and since the metal grip 20 of the hand tool has a circular arc surface, embossing cannot be performed, although the shape of the metal grip 20 of the hand tool is relatively beautiful, and the grip feeling when gripping is held. It is also preferable, but the anti-slip effect at the time of holding is poor, and it is easy to loosen, and it is dangerous to use.

Please refer to the third figure: a schematic plan view of the third formula. The third type of hand tool metal grip 30 is mainly to form a plurality of straight grooves 3 on the curved surface. 1. Since the metal grip 30 of the hand tool has a curved surface, it is impossible to emboss, and only a plurality of straight grooves 31 can be used to increase the anti-slip effect when holding, although the shape of the metal grip 30 of the hand tool is relatively beautiful. The grip is also better when held, but the anti-slip effect is poor when gripping, and it is easy to loosen, which is dangerous to use.

Please refer to the fourth figure: a schematic plan view of the fourth formula. The hand tool metal grip 40 of the fourth type is mainly provided with two annular grooves 41 in front of and behind the flat surface, and a grid-like embossing 42 is formed on the flat surface of the metal grip 40 of the hand tool. It can increase the anti-slip effect when holding, but it can only be applied to the flat surface. The scope of application is narrow. It not only limits the shape of the metal grip 40 of the hand tool, but also affects the grip feeling when holding.

Please refer to the fifth figure: a schematic plan view of the fifth formula. The hand tool metal grip 50 of the fifth type is mainly provided with two annular grooves 51 in front of the circular arc surface and an annular groove 51 at the rear, since the metal grip 50 of the hand tool is an arc The surface is not embossed, although the metal grip 50 of the hand tool has a beautiful appearance and a good grip when held, but the anti-slip effect during handling is poor, and it is easy to loose, and it is dangerous to use.

Please refer to the sixth figure: it is the schematic diagram of the action before the second type of embossing. As shown in the seventh figure, it is a schematic diagram of the action of the second type of embossing. The hand tool metal grip 20 of the second embodiment is mainly used to drive the first driven embossing roller 24 and the second driven embossing roller 25 by the active embossing roller 23 when the embossing 22 is formed. The embossing roller 23 and the first and second driven embossing rollers 24, 25 follow the radial circumference of the hand tool metal grip 20, and press the grid-like pressure on the flat surface between the annular grooves 21. Flower 22.

The inventor is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and has actively invested in the spirit of innovation and improvement in response to the existing problems and lacks of the anti-slip technology of the traditional hand tool metal grip. Hand tool metal grip anti-slip process.

The technical means applied to solve the problem and the effect of the prior art are: along the axial direction of the metal grip of the hand tool, on the curved surface or curved surface of the metal grip of the hand tool, using stamping or rolling forming The method has a plurality of anti-slip parts with patterns, bumps or pits, so as to increase the anti-slip effect and excellent grip feeling during the grip, and the effect is improved, and the main purpose is achieved.
