Description

Technical Field

[0001] The present invention relates to an electroplating device, in particular to a device for thickening a sand plating layer. Background Art

[0002] At present, diamond wire saws are generally straight. When performing circular cutting, the wire saw needs to be perpendicular to the cutting surface, and then the wire saw moves along a circular trajectory perpendicular to the cutting surface. At the same time, the wire saw moves up and down at a certain frequency to cut an object. This operation method has very high requirements for the accuracy of the cutting equipment, and the movement of the wire saw often needs to be realized by combining programming, making the manual operation difficult. All the above technical problems can be solved by producing an annular cutting wire, that is, the cutting wire is a hard annular wire saw. During use, only need to position the annular wire saw and then make it rotate around the center of the circle and move along the cutting depth direction at the same time. However, in the prior art, there is no diamond sand plating equipment for manufacturing annular cutting wires. Summary of the Invention

The thickening electroplating tank 21 is carried on the bottom support platform 221 with an upward opening. A support frame 222 is provided at the side of the thickening electroplating tank 21. A vertical electric push rod is provided on the support frame 222. A horizontal rectangular back plate 23 is fixed on the telescopic lifting rod 271 of the electric push rod. The top end of the electric push rod is fixedly connected to the bottom surface of the top plate 272 horizontally fixed on the rear side wall of the back plate 23. Vertical guide rods 28 are provided on both sides of the electric push rod. The two ends of the guide rod 28 are fixed on the support frame 222. The guide rod 28 is inserted into the sliding sleeve 281 fixed on the rear side wall of the back plate 23 and is in sliding contact with the sliding sleeve 281.

[0027] The upper tension wheels 24 and the lower tension wheels 25 are both located at the upper two ends of the thickening electroplating tank 21.

A number of wire placement grooves 244 are provided along the circumference on the outer rings of the upper tension wheels 24 and the lower tension wheels 25. To prevent the wire placement grooves 244 from wearing the diamond sand plated on the annular cutting line, the upper tension wheels 24 and the lower tension wheels 25 are both made of polyurethane material. To ensure that the annular cutting line does not slide in the wire placement groove, uneven patterns are provided on the bottom and both side walls of the wire placement groove 244.

[0028] The upper tension wheel 24 is composed of a rotating shaft 241, a connecting plate 242 and an upper positioning shaft 243 that are integrally Z-shaped and sequentially rotationally connected. The end of the upper positioning shaft 243 away from the connecting plate 242 is fixedly connected to the back plate 23. The end of the rotating shaft 241 away from the connecting plate 242 is vertically fixedly connected to the end face of the upper tension wheel 24, so that the upper tension wheel 24 can rotate along the axis of the upper positioning shaft 243. A lower positioning shaft 251 is rotatably provided at the end face of the lower tension wheel 25. The lower positioning shaft 251 is fixedly connected to the front side wall of the back plate 23. A motor is provided inside the rotating shaft 241 or the lower positioning shaft 251, and the motor drives the upper tension wheel 24 or the lower tension wheel 25 to rotate.

[0029] To fix the position of the upper tension wheel 24, a threaded hole plate 231 is fixed on the front side wall of the back plate 23. A number of threaded holes are provided on the threaded hole plate 231. To increase the extension angle of the threaded holes, the threaded hole plate 231 extends outward from both sides of the back plate 23. A tensioning screw rod 232 is screwed into its threaded hole. A mini cylinder is provided between the connecting plate 242 of the upper tension wheel 24 and the tensioning screw rod 232. Fixed collar rings are provided at the bottom end of the cylinder and the free end of its piston rod. The two fixed collar rings are respectively movably sleeved in the connecting rings 2421 provided on the side walls of the tensioning screw rod 232 and the connecting plate 242.

[0030] During use, place the annular cutting wire in the wire placement groove 244 of the upper tension pulley 24 in the shape of an external circumcircle, adjust the telescopic length of the mini cylinder, so that the annular cutting wire is clamped in the wire placement groove 244 and can rotate with the rotation of the upper tension pulley 24 or the upper tension pulley 24. Then start the electric push rod to sink the annular cutting wire into the electroplating solution in the thickened electroplating tank 21 and connect the power supply to carry out sand plating.

[0031] The fixed connection method described in the text is threaded connection or welding.
