Description

Material supporting device for double-head cutting saw

Technical Field

The utility model relates to the field of door and window cutting, in particular to a material supporting device for a double-head cutting saw.

Background

Now, in order to realize the processing steps of once-used fixed length and bevel angle cutting on two end positions of a door and window section bar, a double-head cutting saw device is designed, as shown in fig. 1, the double-head cutting saw is provided with double work tables, the double work tables respectively cut two ends of the section bar, and one work table can move, so that the accurate cutting processing on the length of the section bar can be realized.

In our life, as shown in fig. 7, by holding a long plastic pipe with one hand, it is found that the other end of the plastic pipe is bent downward, and this phenomenon is combined with the fact that when a double-end cutting saw is used to cut a section bar which is long in processing length and made of plastic, the section bar itself is low in hardness due to the plastic material, and when the length is long, the middle part of the section bar is suspended without a support, and the middle part has signs of sinking when the two ends of the section bar are clamped and fastened. For plastic materials or other materials with low hardness, the sinking acting force in the middle of the profile can be opposite to the clamping and fixing acting force at the two ends, so that the mutual contact position of the two acting forces becomes a stress point, and the bending is easy. And when cutting, the cutting action of both ends cutting saw bit in rotatory also can produce the effort that rocks to profile itself, under this kind of circumstances, has further increased the atress effect of atress point, under the influence of multiple effort, can lead to the inaccuracy of profile cutting terminal surface, and the material warp, influences the leakproofness, the aesthetic property of concatenation between the profile. In the prior art, aiming at the situation, a worker can place a support at the centremost position of the section bar when cutting, and after cutting is finished, the support is used for moving the worktable in the double-head cutting saw, so that the movement of the worktable is not influenced. However, the randomly found support can only be supported properly, and its structure cannot be matched with the position of the base frame in the double-head cutting saw, so that the support is easy to topple, and not all workshops can have proper support objects to support the middle suspension position of the cutting profile.

Therefore, based on the problems described in the foregoing, it is desirable to design a material supporting device that can cope with the double-end cutting saw, and support the section bar between the two work tables during the processing, and that can not affect the requirement that one of the work tables needs to be moved in the two work tables.
