Description

a sharpener

technical field

The utility model relates to the technical field of sharpening tools, in particular to a sharpening machine.

Background technique

Historically, the cutting edges of cemented carbide turning tools, high-speed steel planing knives, and blades are generally ground by hand. The operation is labor-intensive and inefficient, which wastes time and materials. In order to improve the efficiency of knife sharpening, people have invented many kinds of knife sharpeners to replace manual grinding, which reduces the labor intensity of workers and improves work efficiency. Knives have a narrow scope of application, while some knife sharpeners with a slightly wider scope of application often fail to meet the requirements of use due to the uneven force of the operator during the entire sharpening process, resulting in poor consistency of the cutting edge.

Utility model content

In view of the above-mentioned defects, the utility model provides a knife sharpening machine, which can grind various kinds of knives, and the force is uniform during the grinding process, and the consistency of the cutting edge is good.

In order to achieve the above object, the technical solution adopted by the utility model is: a sharpening machine, including a workbench, a support frame is arranged at the rear of the workbench, a motor is arranged on the support frame, and the motor controls two output Shaft, a large grinding wheel with a circular arc-shaped grinding surface is set on one output shaft, and a cup-shaped small grinding wheel is set on the other output shaft parallel to the longitudinal direction; a base is set on the front of the workbench, and a lateral movement is set on the base The working platform, the horizontally moving working platform is provided with a left moving working platform along the longitudinal direction near the small grinding wheel, a rotary knife rest base is set on the left moving working platform, a knife rest is set on the rotary knife rest base, and a knife pressing groove is arranged on the knife rest; The horizontally moving working platform is provided with a right moving working platform along the longitudinal direction near the large grinding wheel, and a double tool holder is arranged on the right moving working platform, two sharpening grooves are arranged on the double tool holder, and a pressing plate is arranged on the double tool holder .

Further, a pull handle is provided on the base of the rotary knife holder, which can be used to adjust the angle of the knife.

Further, a lifting slider that can be used to adjust the height of the double-position knife rest is provided between the double-position knife rest and the right movable working platform.

Further, the support frame is provided with a small bracket on the outside close to the small grinding wheel, and a mobile base that moves laterally is provided on the small bracket, and a lateral feed mechanism is provided on the lateral feed mechanism, and a dressing diamond pen is provided on the lateral feed mechanism.

Further, the support frame is provided with a large support near the outer side of the large grinding wheel, and a movable frame capable of lateral feeding is provided on the large support, and a rotary dressing frame with a trimming arc grinding wheel cutter is provided on the mobile frame, and a rocking handle is arranged on the dressing frame .

The knife grinder of the utility model is provided with a large grinding wheel and a small grinding wheel for sharpening the knife. The small grinding wheel is a cup-shaped grinding wheel. The grinding surface of the large grinding wheel is arc-shaped for cutting edge or cutting edge on both sides, and the double-position tool holder on the near side can adjust the tool to be ground to the left or right side of the grinding wheel, so as to grind one side of the arc cutting edge The arc cutter is equipped with two sets of trimmers on the sharpening machine. When the grinding wheel wears out during the grinding process, the arc and flat grinding wheels can be trimmed in time to ensure that the cutting edge of the knife is sharp. The utility model can grind more This kind of tool has uniform strength during the grinding process and good consistency of the cutting edge.
