Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant ball processing, and specifically relates to a wear-resistant ball grinding device. Background Art

[0002] Wear-resistant balls are widely used in ball mills in the mining, cement, electric power, metallurgy and other industries to grind materials such as ores and cement clinker. Their quality directly affects the operating efficiency, energy consumption and equipment life of the ball mill. High-quality wear-resistant balls have excellent wear resistance, hardness and toughness, and can maintain a stable shape and size during long-term grinding processes, reducing wear on the ball mill cylinder and liner, improving production efficiency and reducing production costs. Laser grinding uses a high-energy laser beam to irradiate the surface of the wear-resistant ball, causing the surface material to instantly melt, evaporate or gasify, thereby achieving the purpose of removing surface defects and improving surface finish.

[0003] It is difficult for the laser grinding device in the prior art to grind all surfaces of the wear-resistant ball, resulting in grinding dead corners. The utility model solves the above problem. Utility Model Content

[0004] In order to solve the technical problem that the laser grinding device in the prior art is difficult to grind all surfaces of the wear-resistant ball, resulting in grinding dead corners, the utility model provides a wear-resistant ball grinding device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant ball grinding device, comprising: a wear-resistant ball channel, the wear-resistant ball channel is arranged to be tilted downward along the inlet end, the cross-section of the bottom wall of the wear-resistant ball channel is semicircular, the diameter of the semicircle is equal to the diameter of the wear-resistant ball, the wear-resistant ball channel is provided with multiple sections, adjacent wear-resistant ball channels are connected and are vertical when viewed from above, a laser head is connected to the top wall of each section of the wear-resistant ball channel, the laser head emits a laser covering the lower part of the wear-resistant ball channel, the laser head is connected to the power supply through an electric wire, and the wear-resistant ball channel is connected to the base plate through a bracket.

[0006] Preferably, the inlet end of the wear-resistant ball channel is connected with a guide groove plate.

[0007] Preferably, an electromagnet is provided at the lower portion of the wear-resistant ball channel, and an electromagnet is provided in parallel at the lower portion of each wear-resistant ball channel, and the electromagnet is connected to the bottom plate through a magnet bracket.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] By controlling the wear-resistant balls to roll in different sections of the wear-resistant ball channel which is vertical when viewed from above, and changing the angle of the wear-resistant balls, different surfaces of the wear-resistant balls are covered by the laser of the upper laser head. The surface material of the wear-resistant balls melts, evaporates or gasifies instantly, and there is no dead angle in the grinding.

[0010] The electromagnet generates a vertical downward attraction to the wear-resistant balls. The magnetic force of the electromagnet is controlled by controlling the current passing through the electromagnet to change the speed of the wear-resistant balls in the wear-resistant ball channel.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0016] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0017] The following is combined with Figure 1-2 This embodiment describes a wear-resistant ball grinding device, including: a wear-resistant ball channel 1, which is arranged to be tilted downward along the inlet end. The cross-section of the inner bottom wall of the wear-resistant ball channel 1 is semicircular, and the diameter of the semicircle is equal to the diameter of the wear-resistant ball. The wear-resistant ball channel 1 has multiple sections, and adjacent wear-resistant ball channels 1 are connected and vertical when viewed from above. A laser head 2 is connected to the top wall of each section of the wear-resistant ball channel 1. The laser head 2 emits a laser that covers the lower part of the wear-resistant ball channel 1. The laser head 2 is connected to a power supply via a wire 3. The wear-resistant ball channel 1 is connected to a base plate 5 via a bracket 4.

[0018] Place the wear-resistant ball inside the wear-resistant ball channel 1 through the entrance end of the wear-resistant ball channel 1, start the wear-resistant ball to roll along the inner bottom wall of the inclined wear-resistant ball channel 1, and pass through the area covered by the upper laser head 2 during the rolling process. The surface material of the rolling wear-resistant ball instantly melts, evaporates or gasifies, and then the wear-resistant ball moves to the intersection of the two wear-resistant ball channels 1 and changes direction to roll. After changing direction, the rolling surface of the wear-resistant ball changes, and the wear-resistant ball surface that the previous laser head 2 does not cover is covered by the new laser head 2. After multiple changes in direction, all surfaces of the wear-resistant ball are polished several times and completed.

[0019] The inlet end of the wear-resistant ball channel 1 is connected to a guide groove plate 6;

[0020] The guide slot plate 6 makes ball injection more convenient.

[0021] An electromagnet 7 is provided at the bottom of the wear-resistant ball channel 1. An electromagnet 7 is provided in parallel at the bottom of each wear-resistant ball channel 1. The electromagnet 7 is connected to the bottom plate 5 through a magnet bracket 8.

[0022] The electromagnet 7 generates a vertical downward attraction to the wear-resistant balls. By controlling the current passing through the electromagnet 7, the magnetic force of the electromagnet 7 is controlled to change the speed of the wear-resistant balls in the wear-resistant ball channel, thereby increasing the grinding time to adapt to wear-resistant balls with different surfaces and different grinding requirements.
