1 Special clamping device for machining the outer circumference of sheet workpiece without center grinding machine ZL201320437520.X Sifangda Utility model December 18, 2013
2 Blade holder for cutting the sipe on the blade ZL201320471648.8 Sifangda Utility model January 8, 2014
The special fixture for machining the outer circumference of the sheet workpiece by the centerless grinding machine is to design two oppositely arranged tubular constraining pieces, and the two tubular constraining pieces are assembled into a tubular structure of a semi-open structure, when the outer grinding of the sheet workpiece is required, The plurality of sheet workpieces are placed between the half-opened tubular members composed of two tubular constraining sheets, and the top wires of the two ends are tightened to clamp the sheet workpiece into a cylindrical shape, which is convenient for feeding into the centerless grinding machine. Perform cylindrical grinding.
The blade holder used for cutting the sipe on the blade can hold a plurality of blades, so that the wire electric discharge machine can simultaneously perform cutting sipe processing on a plurality of blades, thereby improving processing efficiency, reducing the number of times of clamping, and reducing the clamping error. Therefore, the accuracy and uniformity of the cut sipe are improved, thereby ensuring the service life of the blade.
The above utility model patents have been applied in the company's products. The acquisition of patents will not have a major impact on the company's production and operation, but it will help protect the company's intellectual property rights, form a continuous innovation mechanism, and enhance the company's core competitiveness.
