A special angle code band sawing machine for the door and window industry

Abstract

The invention discloses a special corner code band saw for the door and window industry. The feeding and clamping mechanism includes a first clamping unit that is stuck on a guide rail and can move reciprocatingly along it. The first clamping unit is driven to reciprocate by a connected feeding cylinder. , corresponding to the first clamping unit is a matched second clamping unit, and the second clamping unit is correspondingly matched with the band saw cutting mechanism; the band saw cutting mechanism includes a band saw installed on the vertical guide post The mounting seat is driven by a master cylinder to move up and down along the vertical guide column. A driving wheel and a driven wheel located on the same horizontal plane are arranged on the band saw mounting seat, and both the driving wheel and the driven wheel are arranged horizontally. The connected power mechanism drives the rotation, and the outer circumference of the driving wheel and the driven wheel is covered with a band saw with the saw blade vertically downward, and the driven wheel is connected with a tensioning mechanism capable of adjusting the distance between it and the driving wheel. This device has completely changed the mechanical form of the traditional corner saw.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a corner code band sawing machine specially used for the door and window industry. Background technique [0002] Corner saw equipment is used to process doors and windows to reinforce the reinforcements used for doors and windows, commonly known as corners. Therefore, the name of the angle code saw comes from this. The so-called corner codes are made of aluminum alloy and then cut into corner codes of different sizes. For many years, the corner saws manufactured by my country's door and window industry have adopted circular saws with a diameter of 500 mm and an inner hole of 30 mm, which are divided into 100 teeth and 120 teeth, with a thickness of 3.8 mm and a width of 4.2 mm. code. Generally, a saw blade needs to be sharpened after being sawed 10,000 times, and the saw blade is useless after sharpening 4 to 5 times. The value of a saw blade is generally around 1,000 yu...

AI Technical Summary

Problems solved by technology

The waste of the above materials will inevitably increase the cost and reduce the profit. The users in the door and window industry are complaining and eagerly looking forward to the advent of a kind of equipment that can save materials. It is known that many door and window equipment manufacturers are also trying to modify the equipment. fruit

[0004] Although Chinese patent applications CN2550121Y, CN 102554343A, and CN 103769937A disclose different automatic sawing machines, they all use circular saws, which cannot solve the problem of waste of aluminum alloy profiles

In the industry, it is believed that the conventional band sawing machine is not suitable for corner cutting, or that the operation is very difficult. Therefore, there is no use of band saws to cut aluminum alloy profiles as corner cutting.
