Detailed Description

The first embodiment.

The operation method of the embodiment is as follows: 1. placing the material on a front end feeding platform 4 and between a front alignment clamp 5 and a rear alignment clamp 6; 2. before starting, aligning a laser ranging sensor 10 of the clamp 5, and measuring the distance between the laser ranging sensor and the material to obtain the stroke of the slide block 8 needing to move; 3. before starting, the electric slide rail 7 of the alignment fixture 5 drives the two long clamping plates 9 to move oppositely, and when the slide block 8 finishes a stroke needing to move, the slide block stops moving, and at the moment, the material is clamped by the long clamping plates 9; 4. after the electric slide rail 7 of the alignment fixture 6 is started, the slide block 8 drives the roller 11 to move towards the material direction, the moving stroke of the slide block 8 is the same as that of the front alignment fixture 5, and the roller 11 is just in contact with the material when the slide block 8 stops moving; 5. the worker operates the band saw blade to cut at the rear part of the band sawing machine body 1 and continuously drags the material to be fed into the cutting table 2.

In this embodiment, the long splint 9 of the front alignment jig 5 clamps the material, but the clamping effect is not to achieve fixation, but the long splint 9 is attached to the material from two sides by using the length of the long splint 9, so that the material direction is parallel to the long splint 9, thereby achieving the alignment effect. Therefore, the long clamping plate 9 clamps the material to ensure that the material can be dragged, and the clamping force cannot be too large.

The purpose of the rear alignment jig 6 is that it is impossible to feed the material individually for cutting, and in order to improve the cutting efficiency, a plurality of materials are fed together for each cutting, and if only one front alignment jig 5 is aligned, the end of the material is easily spread radially when it is fed to the edge of the cutting table 2, and like the case of holding a bundle of wires by hand, it is generally more likely to appear radially when it is held more tightly. To this situation can theoretically move preceding clamp 5 well to the position that is close to cutting table 2, but material length is very long, and preceding clamp 5 well is too close to cutting table 2, and the part of material before getting into preceding clamp 5 well produces the bending easily, also appears the material swing when dragging the material and rocks easily, leads to dragging the material difficulty. Therefore, the front aligning clamp 5 has to keep a certain distance from the cutting table 2, and the back aligning clamp 6 is required to be arranged at a position close to the edge of the cutting table 2, so that the material aligning effect can be guaranteed, and the material can be easily dragged after being aligned.

Because the long splint 9 is long, the attachment area with the material is large, and a good alignment effect is achieved, the pursuit of the alignment effect of the post-alignment fixture 6 is weakened, the post-alignment fixture 6 only keeps a certain alignment effect, namely, the material cannot be diffused or unstable in the process of being fed into the cutting table 2, and meanwhile, the friction force of the material to the material is reduced, so that the material is simply aligned by adopting the roller 11, and the material can be dragged more smoothly.

In this embodiment, the laser distance measuring sensors 10 are mounted on the left long splint 9 and the right long splint 9, and the distance between the left long splint 9 and the material is assumed to be a, and the distance between the right long splint 9 and the material is assumed to be B, and the distance is calculated

The displacement stroke of the long clamping plate 9 and the displacement stroke of the slide block 8 can be obtained.

In this embodiment, the electric slide rail 7 is a double-slide-block scheme, and the same double-slide-block electric slide rail 7 has two slide blocks 8, and two long clamp plates 9 of the front alignment fixture 5 or two rollers 11 of the rear alignment fixture 6 can be respectively installed. The principle that the electric slide rail 7 realizes the movement of the slide block 8 generally uses a screw rod mechanism, the double-slide-block slide rail is provided with a screw rod with two ends respectively being a positive screw and a negative screw, one slide block 8 moves on the positive screw, and the other slide block 8 moves on the negative screw to realize the opposite movement of the slide block 8. Because the friction force facing the front aligning fixture 5 is larger, for pursuing stability, the electric slide rail 7 of the front aligning fixture 5 can adopt the electric slide rail 7 with the parameter size larger than that of the rear aligning fixture 6, the electric slide rails 7 of the front aligning fixture 5 and the rear aligning fixture 7 have the same structure and use and the same effect, so that the front aligning fixture and the rear aligning fixture do not need to be distinguished, and the electric slide rails 7 can adopt mature products on the market.

Be limited to current band sawing machine scheme limitation, the band saw blade needs the water spray when the cutting, leads to the easy splash of water of during operation to splash four times, for avoiding water direct injection to adjust the problem such as cause the electronic equipment short circuit on the anchor clamps 6 well all around, set up storage tank a16 on the front end feed platform 4 and adjust anchor clamps 5 well before holding, set up storage tank b17 and hold the back and adjust anchor clamps 6 well. In addition, a drainage channel 18 may be provided in each of the receiving groove a16 and the receiving groove b17, and the drainage channels 18 may drain water from the front end feeding platform 4. For better waterproof, can also set up breakwater a19 and block the water that erupts from the cutting bed 2, this breakwater can set up on taking the former anchor clamps 3's of sawing machine body 1 position, can not occupy cutting bed 2 space promptly, also adjust anchor clamps 6 enough closely after the distance, it is better to shelter from the performance. Since the laser distance measuring sensor 10 of the front aligning fixture 5 must be located outside the accommodating groove a16, the influence of the waterproof scheme on the front feeding platform 4 is limited, and to solve this problem, a water baffle b20 is also provided near the accommodating groove a 16. It should be noted that the water baffle a or the water baffle b needs to be disconnected in the middle, so as to facilitate the material to pass through.

Example two.

The present embodiment is used to solve the problem of difficult clamping of non-plate-shaped and block-shaped materials, wherein the most common material shape is an L-shaped material, which results in a small contact area between the long splint 9 and the long splint, and limited clamping and alignment effects. To solve this problem, an extension insert 12 is provided, the height of the extension insert 12 is smaller than the height of the long clamp plate 9, but the length is equal to the height, and the width is determined by the size of the material itself, so that the extension insert 12 can be a plurality of different sizes. Taking fig. 5 and 6 as an example, when the inserting rod 14 of the expansion insert 12 is inserted into the installation through hole 15, the geometrical shape with a right angle formed by the inserting strip 13 and the long clamping plate 9 is just matched with the shape of the L-shaped material, and the clamping effect is good. The limiting mechanism on the inserting rod 14 can adopt any existing scheme, such as a thread scheme or a buckling scheme, and the like, as long as the inserting strip 13 can be stably inserted on the long clamping plate 9.
