Sawing unit device

Technical Field

The utility model relates to a section bar cutting equipment field especially relates to a saw cut unit device.

Background

At present, along with the increasing use of aluminum profiles in people's lives, the cutting and processing equipment of aluminum profiles is widely applied. In order to facilitate the installation of the aluminum profile, the end face of the aluminum profile is generally cut into 45 degrees, 90 degrees and 135 degrees, and accordingly the cutting machine set of the aluminum profile is correspondingly provided with saw blades with three angles for cutting so as to facilitate the one-step processing and forming of the aluminum profiles with different angles.

Because the unit of saw cutting of three saw bit, one of them saw bit is located the feed end, make the feeding space of its feed end less, it is narrower to be close to saw cutting center channel more, need fix a position the section bar at the feed end during cutting, when fixing a position the section bar of feed end position among the prior art, generally use the cylinder to promote the push pedal and fix a position the section bar top tightly, the locating surface in the telescopic link direct perpendicular to of cylinder, this kind of setting mode can be because of the limited position that must set up keeping away from saw cutting center in space, this kind of off tracking easily when the cutting that just leads to the section bar, the location is unreliable, produce great cutting error. In addition, when the saw blade in the prior art retracts after cutting the profile, one is to apply a tangential force to the profile to make the profile easy to deflect, and the other is to apply a machining error to the cut section again, and the service life of the saw blade is affected by the friction; and saw cut among the prior art and directly follow band conveyer after, utilize the friction to drive the section bar and carry, this has just caused to make the section bar that cuts off stop on the locating platform and not carry along with the band because of frictional force is not enough when carrying shorter section bar. This is the current state of the art.

Therefore, to the current situation of aluminium alloy cutting equipment among the above-mentioned prior art, it is the problem that the urgent need be solved to develop a location effectual and do benefit to the saw cutting unit device that the cutting was carried.

SUMMERY OF THE UTILITY MODEL

On the one hand, "saw cut directly following band conveyer at the back in order to overcome among the prior art among the above-mentioned prior art, utilize the friction to drive the section bar and carry, this has just caused when carrying shorter section bar because of frictional force not enough make the section bar that cuts off stop not following band conveyer on the location bench" not enough, the utility model provides a saw cut unit device can reach and does benefit to the purpose that the cutting was carried.
