Description

Technical Field

[0001] The utility model relates to the field of impact mill accessories, in particular to a novel anti-cracking and wear-resistant grinding needle for a needle-type impact mill. Background Art

[0002] In the impact grinding equipment, the grinding needle is driven by a motor to rotate at high speed, generating strong centrifugal force and impact force. These forces cause the grinding needle to collide and rub with the surface of the workpiece at high speed, thereby removing impurities, oxides, etc. on the surface, achieving the effects of grinding, polishing and surface treatment.

[0003] However, traditional grinding pins have a short service life and are extremely prone to cracking, which not only significantly increases the factory's cost expenditure, but also seriously reduces work efficiency and is more likely to cause damage to the impact grinding equipment itself. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of needle-type impact grinding anti-crack wear-resistant grinding needle to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it comprises a grinding needle body, the surface of the grinding needle body is provided with tiny concave-convex parts, and the surface of the tiny concave-convex parts is electroplated with a chrome layer.

[0006] As a preferred embodiment of the present invention, the surface of the grinding needle body is ground by a grinder to produce tiny bumps.

[0007] As a preferred embodiment of the present invention, the surface of the grinding needle body adopts electrochromium plating technology.

[0008] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0009] 1. The utility model significantly improves the wear resistance of the grinding needle body and extends its service life by arranging tiny concave-convex structures and a chrome-plated layer on the surface of the grinding needle body. At the same time, the tiny concave-convex structure also increases the bonding force between the chrome-plated layer and the grinding needle body, effectively preventing the chrome-plated layer from falling off and cracking during impact and wear. In addition, the chrome-plated layer has a certain lubricating effect, which can reduce the friction coefficient between the grinding needle body and the material to be processed, thereby improving processing efficiency and quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0011] Reference numerals: grinding needle body 1 . DETAILED DESCRIPTION

[0012] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0013] like Figure 1 As shown, the utility model proposes a new type of needle-type impact grinding anti-cracking and wear-resistant grinding needle, which includes a grinding needle body 1. The grinding needle body 1 is made of high-strength and high-hardness material to ensure that it can maintain stable performance under impact and wear conditions. The surface of the grinding needle body 1 is provided with tiny bumps. The surface of the grinding needle body 1 is polished by a precision grinder to form a tiny bump structure, which enhances the bonding force between the chrome plating layer and the grinding needle body 1, thereby improving the overall wear resistance and crack resistance. The tiny bump surface is electroplated with a chrome layer. On the tiny bump surface, a uniform chrome plating layer is plated by advanced electroplating chrome technology. The chrome plating layer has extremely high hardness and wear resistance, which can further protect the grinding needle body 1 from wear and corrosion. At the same time, the chrome plating layer also has a certain lubricating effect, which can reduce the friction coefficient between the grinding needle and the material to be processed and improve processing efficiency.

[0014] The surface of the grinding needle body 1 is grinded by a grinder to produce tiny bumps. The grinding needle body 1 first reduces the quenching time to lower the hardness, and then is grinded by a grinder to produce tiny bumps on the surface of the grinding needle body 1.

[0015] The surface of the grinding needle body 1 adopts electrochromium plating technology. After the surface of the grinding needle body 1 is polished by a grinder, the surface of the grinding needle body 1 is chrome-plated by electric current. The tiny bumps on the surface of the grinding needle body 1 can effectively absorb chromium on the surface of the grinding needle, making the grinding needle body 1 more wear-resistant and not easy to crack.

[0016] During use, the staff first reduces the quenching time of the grinding needle body 1 in the quenching stage, thereby reducing the hardness of the grinding needle body 1. Then the staff can move the grinding needle body 1 to the grinding machine and start the grinder to grind the surface of the grinding needle body 1. After grinding, the grinding needle body 1 will produce tiny bumps. Then, the staff can use electric current to chrome-plate the surface of the grinding needle body 1. The tiny bumps on the surface of the grinding needle body 1 can effectively absorb chromium on the surface of the grinding needle, making the grinding needle body 1 more wear-resistant and not easy to crack.

[0017] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents of such scope and metes and bounds.
