Plate polishing and edge sawing device for fire-fighting box body production line

Abstract

The invention discloses a plate polishing and edge sawing device for a fire-fighting box body production line. The plate polishing and edge sawing device comprises a base, a positioning plate, a clamping part, a sliding seat, a translation part, a polishing motor, a self-adjusting part and a polishing grinding wheel. The self-adjusting part comprises an adjusting seat, a telescopic rod, a clampingblock, a clamping groove and a compression spring. The plate polishing and edge sawing device for the fire-fighting box body production line has the beneficial effects that the self-adjusting part isarranged, and the end face of the polishing grinding wheel can move close to the end of a plate through elastic abutting of the compression spring to the clamping block, so that the polishing grinding wheel can adapt to plates with uneven ends to carry out polishing and grinding, and the working efficiency is improved. The clamping part is composed of a rotating shaft, a nut base, connecting rods, a fixing part, rotating arms and abutting columns, the two connecting rods pull the two rotating arms to rotate respectively through rotation of the rotating shaft, the two abutting columns clamp the plate synchronously, and the tilting phenomenon caused by asynchronous stress on the two sides in the plate clamping process is avoided.

Description

technical field [0001] The invention relates to the field of polishing equipment, in particular to a polishing and sawing device for plates used in the production line of fire box boxes. Background technique [0002] The fire box refers to the box used to store fire hydrants. It is used to extinguish fires when a fire occurs. It must be equipped with water belts, water guns, etc. The installation methods include surface-mounted, concealed, and semi-concealed. There are many types of fire boxes. [0003] The body of the fire box is generally a sheet metal part. When the sheet metal part is processed, it is generally cut and sawed, then polished, and then bent. The edge after cutting is generally burr and burr It is large and needs to be polished. At present, the workers mainly hold the grinder, and the grinder sticks to the edge after cutting for grinding and polishing. This method increases the labor intensity of the workers, and the safety factor is low, which is prone to s...

[0003] The body of the fire box is generally a sheet metal part. When the sheet metal part is processed, it is generally cut and sawed, then polished, and then bent. The edge after cutting is generally burr and burr It is large and needs to be polished. At present, the workers mainly hold the grinder, and the grinder sticks to the edge after cutting for grinding and polishing. This method increases the labor intensity of the workers, and the safety factor is low, which is prone to safety accidents In view of this, in the current prior art, equipment for polishing and grinding instead of manpower has appeared. These grinding equipment basically do not require workers to operate manually, which greatly reduces labor intensity and reduces potential safety hazards. However, the existing The polishing and grinding equipment in the technology generally drives the polishing wheel to rotate by the polishing motor, and then the polishing motor moves (or the plate moves horizontally) to polish the plate. Since the distance between the polishing wheel and the edge of the plate is fixed, when the end of the plate is at There is a large deviation during cutting, so that when the end is not neat, and the position of the polishing wheel is fixed, when the polishing wheel is polishing the end, some areas may not be polished, or some areas are more prominent, resulting in the polishing wheel The amount of wear is large, and at this time it can only be polished manually by workers, which leads to the problem of low work efficiency
