Description

Cutting tool with saw blade for ring cutting

Technical Field

The utility model belongs to ring processing equipment field, more specifically say, relate to a frock is tailor with band saw blade to ring cutting.

Background

The band saw is a machine which uses a ring-shaped endless band saw blade to surround two saw wheels and makes continuous rotary motion in the same direction to perform saw cutting, and the band saw has high efficiency and small saw path, and is the most widely used main saw in Chinese material manufacturing equipment.

In the ring processing field, the ring blank is usually cut by adopting an annular band saw, and along with the prolonging of the service life of the band saw blade, the cutting edge of the band saw blade gradually becomes dull, or the saw teeth are lost due to the action of external force, so that the band saw is more likely to be broken. In order to save manufacturing cost better, the band saw that dismantles needs to be repaired, get rid of the damaged section promptly, the band saw section that uses up is makeed up length and is carried out welded connection, form usable new band saw, wherein, tailor the damaged section and need make the kneck of treating welding band saw blade two welding ends level and smooth, two joint shape size are the same or close, contact surface heating is even when guaranteeing the welding, and band saw blade thickness is thicker than ordinary saw bit, ordinary pliers can't be tailor it, if use large-scale equipment such as plate shearing machine, need purchase equipment alone, the cost consumption has been increased, the original intention of repairing band saw blade saving cost has been deviated from.

Through retrieval, the Chinese patent publication number: CN 205764217U; the publication date is as follows: 2016, 12 months, 7 days; the utility model discloses a saw blade sheet cutting device, including the frame that is L shape, be provided with on the horizontal segment of frame and cut the base, it is connected with the sheet carriage to cut the base, it is provided with along the vertical direction slip and cuts the frame to cut on the vertical segment of frame, the fixed alloy of being provided with in bottom of cutting the frame is cut the blade, be provided with the gliding actuating mechanism of drive cutting frame in the frame, actuating mechanism is including setting up the actuating cylinder that drives in the frame, the actuating lever of being connected with the piston rod looks rotation that drives actuating cylinder, the connecting axle of tip looks fixed connection of middle part and actuating lever, connect in the drive swing arm at connecting axle both ends, the one end of drive swing arm and the both ends looks fixed connection of connecting axle, the other end of drive swing arm with cut the frame and rotate through rolling bearing mutually and be connected. The device of this application compares in plate shearing machine, and the structure is little, can accomplish the work of tailorring to the band saw blade, but the device is driven by the cylinder, has promoted device cost, and the shearing force that needs when tailorring is too big, causes the damage of blade or actuating arm easily.
