Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a vertical abrasive feeding device for electroplated diamond wire. Background Technology

[0002] Diamond wire saws, as a new cutting technology applied to hard and brittle materials, are rapidly replacing traditional cutting techniques. Diamond wire is mainly used for cutting and processing high-hardness and brittle materials such as crystalline silicon, sapphire, and precision ceramics. Due to the high cutting efficiency, excellent cutting quality, and low material loss of electroplated diamond wire, it has even greater advantages under the trend of diamond wire refinement. With its widespread use in the materials field, the quality control of its production process is becoming increasingly strict. For diamond wire to have good cutting performance, the diamonds coated on the wire must be continuously and uniformly distributed, and the number of abrasive grains on different types of diamond wire also needs to be different.

[0003] Traditional sanding devices mostly use aluminum profiles to make the frame, which is not strong enough. During production, components such as the conductive wheel, conductive wheel bearing seat, and reinforcing barrel often vibrate, leading to quality problems such as sand falling off. The bottom return structure of the inlet conductive wheel group located below does not have a sealing structure, resulting in a poor working environment. The bearings and conductive slip rings are severely corroded by plating solution and steam, and are frequently damaged. On average, the slip rings need to be replaced every 1-2 months, resulting in very high maintenance costs. The structure of the line passing through is not transparent enough, making it impossible to directly observe the sanding condition on the diamond wire.

[0004] Therefore, the problem that the inventors wanted to solve was to design a device with a stable structure, a sealed liquid return structure, and improved transparency for easy observation. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a vertical sand-applying device for electroplating diamond wire, which achieves structural stability, a sealed return liquid structure, and improved transparency for easy observation.

[0006] The technical solution adopted by this utility model device is: a vertical sanding device for electroplating diamond wire, comprising a stainless steel frame, a sand agitator installed at the top of the stainless steel frame, a sand cup installed on the outer side of the output end of the sand agitator, the sand cup being installed at the top of the stainless steel frame, a peristaltic pump installed on the inner side of the top of the stainless steel frame, the peristaltic pump being connected to the sand cup through a pipeline, a connecting aluminum plate installed in the middle of the stainless steel frame through bolts and an insulating plate, a large cone installed at the upper end of the connecting aluminum plate, a reinforcing barrel installed at the upper end of the large cone, a sand adding pipe installed at the top of the reinforcing barrel, the sand adding pipe being connected to the output end of the peristaltic pump through a pipeline. The reinforced tank is connected to a lower liquid inlet on its lower side and an upper liquid return outlet on its upper side. An annular anode titanium basket is located inside the reinforced tank, and a wire-passing titanium tube is located inside the annular anode titanium basket. A long upper sand pipe is connected to the bottom of the large cone, and a small cone is connected to the lower end of the long upper sand pipe. A sand-blocking tee is connected to the lower end of the small cone, and a sand-blocking pipe is connected to the interface of the sand-blocking tee. An upper wire-exit conductive wheel assembly is located at the upper end of the wire-passing titanium tube, and a lower wire-inlet conductive wheel assembly is located at the lower end of the sand-blocking tee. A secondary liquid return tank is located at the bottom of the lower wire-inlet conductive wheel assembly, and the main liquid return tank is connected to the bottom of the secondary liquid return tank.

[0007] A sand collection box is provided at the bottom of the upper lead-out conductive wheel assembly.

[0008] Both the main return tank and the auxiliary return tank are equipped with sealing structures at their ports.

[0009] The large cone, small cone, reinforced barrel, and long sand-filled pipe are all transparent.

[0010] The lower inlet conductive wheel assembly is the cathode.

[0011] The sand cup is connected to an external feeding device.

[0012] The lower end of the lower inlet conductive wheel assembly is located on the inner side of the upper end of the auxiliary return liquid tank.

[0013] The beneficial effects of this utility model device are:

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0018] Example 1: See Figure 1 This is a structural view of the present invention, a vertical sanding device for electroplating diamond wire, comprising a stainless steel frame 22, a sand agitator 1 mounted on top of the frame 22, a sand cup 2 mounted on the outer side of the output end of the sand agitator 1, the sand cup 2 mounted on top of the frame 22, a peristaltic pump 3 mounted on the inner side of the top of the frame 22, the peristaltic pump 3 connected to the sand cup 2 via a pipeline, a connecting aluminum plate 13 mounted in the middle of the frame 22 via bolts and an insulating plate 14, a large cone mounted on the upper end of the connecting aluminum plate 13, a reinforcing barrel 7 mounted on the upper end of the large cone, a sand adding pipe 4 mounted on the top of the reinforcing barrel 7, the sand adding pipe 4 connected to the output end of the peristaltic pump 3 via a pipeline, for reinforcement. The lower side of the barrel 7 is provided with a lower liquid inlet 8, the upper side of the reinforced barrel 7 is provided with an upper liquid return outlet 9, the inner side of the reinforced barrel 7 is provided with an annular anode titanium basket 10, the inner side of the annular anode titanium basket 10 is provided with a wire-passing titanium tube 11, the bottom of the large cone is connected to a long upper sand tube 15, the lower end of the long upper sand tube 15 is connected to a small cone, the lower end of the small cone is connected to a sand-blocking tee 17, the interface of the sand-blocking tee 17 is connected to a sand-blocking tube 18, the upper end of the wire-passing titanium tube 11 is provided with an upper wire-exiting conductive wheel assembly 6 at a relative position, the lower end of the sand-blocking tee 17 is provided with a lower wire-inlet conductive wheel assembly 19, the bottom of the lower wire-inlet conductive wheel assembly 19 is provided with a secondary liquid return tank 21, the bottom of the secondary liquid return tank 21 is connected to a main liquid return tank 20.

[0019] The bottom of the upper lead-out conductive wheel assembly 6 is equipped with a sand receiving box 5 for collecting falling sand, the lower lead-in conductive wheel assembly 19 is the cathode, and the sand cup 2 is connected to an external feeding device.

[0020] The frame used for installation is made of aluminum profiles, which are prone to deformation and have weak strength. The aluminum profile frame is not strong enough. During the production process, components such as conductive wheels, conductive wheel bearing seats and reinforcing barrels often vibrate, resulting in quality problems such as sand falling off. This utility model uses stainless steel as the main body of the mining machine to strengthen the overall strength of the frame.

[0021] The lower end of the lower inlet conductive wheel assembly 19 is located inside the upper end of the auxiliary return liquid tank 21. In traditional sand-grinding devices, the bottom return liquid of the lower inlet conductive wheel assembly 19 does not have a sealing structure, resulting in severe splashing of plating solution, leading to a poor working environment. The bearings and conductive slip rings are severely corroded by plating solution and steam, and are frequently damaged. On average, the slip rings need to be replaced every 1-2 months, resulting in very high maintenance costs. Furthermore, sealing structures are provided at the ports of the main return liquid tank 20 and the auxiliary return liquid tank 21. This utility model provides sealing structures at the interfaces of the main and auxiliary return liquid tanks 21 to improve sealing performance, thereby sealing off plating solution steam. The auxiliary return liquid tank 21 is installed at the bottom of the conductive wheel assembly at the closest distance to prevent plating solution splashing and avoid corrosion of the conductive slip rings and bearings by the plating solution, greatly reducing abnormalities caused by bearing jamming and slip ring damage. The main return liquid tank 20 and the auxiliary return liquid tank 21 are sealed by a sealing structure.

[0022] All parts that pass through the sanding process are made of transparent material, preferably acrylic, to facilitate observation of the amount of sand and the condition of the rigid line. The large cone, small cone, reinforcing barrel 7, and long sanding pipe 15 are all transparent. Shoulder positioning structures are set on the large cone, sanding pipe, small cone, and tee to ensure that the parts are coaxial after assembly. During maintenance, it is easier to adjust the rigid line to the center of each acrylic part, avoiding the risk of the acrylic grinding the rigid line.

[0023] In traditional sanding devices, the upper and lower sets of conductive wheels are usually fixed by cantilever without a limiting structure. Due to long-term tension, the position of the conductive wheels may shift. The conductive wheel set of this utility model is equipped with a limiting mechanism in six directions, which strengthens the conductive wheel set and ensures that the position of the conductive wheels remains unchanged during long-term production. The wire position does not shift, which effectively ensures that the wire is centered on the screw plug and avoids abnormal wire grinding.

[0024] The agitator 1 agitates the diamond abrasive in the agitator cup 2. The peristaltic pump 3 continuously adds abrasive to the inlet pipe. The diamond wire to be coated with abrasive is guided by the lower inlet conductive wheel of the cathode, passes through the sand-blocking tee 17 and enters the small cone 16, the long sand-adding pipe 15, the large cone 12, and the reinforcing tank 7. Finally, it exits from the upper conductive wheel. The diamond abrasive flows from the agitator cup 2 through the sand-adding pipe 4 to the large cone 12, the long sand-adding pipe 4, and the small cone 16. At the same time, the electroplating solution is injected from the lower liquid inlet 8. The upward flow of the liquid impacts the diamond abrasive, making the abrasive and diamond wire fully contact each other, improving adhesion and plating rate. Then the diamond wire enters the reinforcing tank 7. Under the action of the lower inlet conductive wheel group 19 of the cathode, the upper outlet conductive wheel group, and the nickel beads of the anode, a layer of nickel is plated on the surface of the diamond wire, firmly adhering the diamond abrasive to the diamond wire.

[0025] This utility model uses a stainless steel frame and a steel structure to improve the overall strength of the frame. A sealing structure is set at the interface of the main and auxiliary return tanks 21 at the bottom to improve the sealing performance. The main sand passage is made of transparent material to facilitate observation of the sand quantity and the state of the steel line. It achieves the functions of structural stability, sealing of the return structure, and improved transparency for easy observation.
