Description

Disc grinder for producing and repairing flat die end face of bulking machine

Technical Field

The utility model relates to the field of metal workpiece processing, in particular to a disc grinder for producing and repairing a flat die end face of a bulking machine.

Background

The grinding machine is a machine tool for grinding a surface of a metal workpiece using a grinding tool. Most grinding machines are grinding machines using grinding wheels that rotate at high speeds, and a few are grinding machines using other grinding tools such as whetstones, sanding belts, and free abrasive materials, such as honing machines, superfinishing machines, sanding belt grinding machines, and polishing machines.

Bulking machines are devices for processing puffed food, such as rice, corn, soybean, wheat, etc. in daily life. The main working principle is that mechanical energy is converted into heat energy, and the heat generated during machine rotation is used for extruding and cooking food, and the puffed food has the most obvious characteristic of large volume. The bulking machine has various functions, so that the bulking machine can be widely applied to the fields of feed, food, industry and the like, and can be roughly divided into a feed bulking machine, a flour bulking machine, a soybean bulking machine and other types of bulking machines according to the application paths.

When the flat die is used as a key accessory for forming feed pellets, the flat die is required to be ground, and when the flat die of a common bulking machine is used, the discharging end face of the flat die of the bulking machine is continuously rubbed and impacted by a blade in the feed production process to cause uneven end face, namely, the discharging surface of the flat die can generate waves or grooves due to abrasion, so that the quality of the produced pellets is reduced, the continuous production of a production line is prevented, and meanwhile, the service life of a cutter is also reduced due to the waves and the grooves; at this time, the flat die end face needs to be repaired. At present, the repairing method of the flat die end face generally adopts an angle grinder to manually polish the damaged flat die end face, and the method has the advantages of low cost and convenient repairing; the second method is that the enterprises send the flat mould of the bulking machine to suppliers or mechanical processing factories to repair by a surface grinder, and the method has the advantages of high repair precision and more comprehensive repair of the worn part.
