[0002] Knives and scissors grinder is one of the important equipment used to process various metal knives and scissors. It is mainly used to process the plane and curved surface of various metal knives and scissors. However, on the existing knives and scissors grinding machines, the processing of plane and curved surfaces is mostly done by manual adjustment. This operation method has low precision, unstable quality, and low efficiency, which obviously cannot meet the production needs.

The invention discloses a cutter and scissor grinder hydraulic control device and a control method of the cutter and scissor grinder hydraulic control device. The cutter and scissor grinder hydraulic control device comprises a grinding oil cylinder, a clamping oil cylinder and a feeding oil cylinder; the clamping oil cylinder is connected with a hydraulic main pipeline through a second reversing valve; the feeding oil cylinder is connected with the hydraulic main pipeline sequentially through a first one-way throttle valve and a third reversing valve; the grinding oil cylinder is sequentially connected with a first reversing valve, a fourth reversing valve and the hydraulic main pipeline; a second one-way throttle valve and a pressure gauge are connected between the first reversing valve and the hydraulic main pipeline, and the second one-way throttle valve is in parallel connection with the fourth reversing valve; and a counterbalance valve and a one-way valve are arranged on a connecting pipeline between the first reversing valve and the fourth reversing valve. The control device and the control method are mainly used for processing planes and curved surfaces of a variety of metal cutters and scissors, the control device is composed of a left unit and a right unit, the inner and outer surfaces of the cutters and the scissors are respectively processed by the left unit and the right unit, the control device and the control method are applied to mass production of the cutters and the scissors, roughness can reach more than 1.6, and quality is steady. Besides, the cutter and scissor grinder hydraulic control device and the control method of the cutter and scissor grinder hydraulic control device have the advantages of being small in size, high in efficiency, long in service life, compact in structure, convenient to operate, and the like.
Description
technical field [0001] The invention relates to the technical field of hardware machinery, in particular to a hydraulic control device and a control method for a knife-scissor grinder. Background technique [0002] Knives and scissors grinder is one of the important equipment used to process various metal knives and scissors. It is mainly used to process the plane and curved surface of various metal knives and scissors. However, on existing knives and scissors grinders, the processing of planes and curved surfaces is mostly done by manual adjustment. This operation method has low precision, unstable quality, and low efficiency, which obviously cannot meet production needs. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the purpose of the invention is to provide a hydraulic control device for knives and scissors grinders, which is suitable for mass production of knives and scissors, with a roughness of more than 1....
