[0030] Example: Figure 1-5 As shown, a profile sawing and pressing tool for a double-head sawing machine includes a sawing machine bed 1 and a sawing machine table 2. A slide 3 is provided on the sawing machine bed 1, and a sawing machine table 2 is provided on the slide 3. There are two sawing machine tables 2. Both sawing machine tables 2 can be moved and fixed on the slide 3 of the sawing machine bed 1, so that the distance between the two sawing machine tables 2 can be adjusted conveniently to achieve the purpose of sawing profiles 17 of different lengths.

[0031] The end surfaces of the two sawing machine tables 2 away from the sawing machine bed 1 are both stepped end surfaces, each of which is divided into an upper step 4 and a lower step 5, and the upper step 4 and the lower step 5 are an integrated structure.

[0032] A through hole is provided on the side surface of the upper step 4 and the upper end surface of the lower step 5. The length of the through hole on the upper end surface of the lower step 5 is greater than the distance between the profile 17 and the side surface of the upper step 4 after the profile 17 is fixed. The two through holes are connected to form an L-shaped through hole 6. A saw blade 7 is provided in the L-shaped through hole 6 to facilitate the saw blade 7 to extend and retract on the sawing table 2 to cut the profile 17.

[0033] A limit block 8 is arranged on the upper end surface of the lower step 5 , the limit block 8 is arranged on the inner side, and the L-shaped through hole 6 is arranged on the outer side, that is, the saw blade 7 is arranged on the outer side and is arranged vertically with the limit block 8 .

[0034] A special-shaped pressing block is also arranged on the upper end surface of the lower step 5. The special-shaped pressing block and the limit block 8 are arranged in a horizontal arrangement. The special-shaped pressing block includes a fixed pressing block 9 and a movable pressing block 10. The fixed pressing block 9 and the movable pressing block 10 are both arranged on the upper end surface of the lower step 5 and are relatively separated. A profile placement cavity 11 is formed in the middle. The cavity shape of the profile placement cavity 11 matches the external contour of the profile 17 to be processed, which can achieve full contact between the pressing block and the profile 17, realize the fixation of the profile 17 before sawing, and ensure the sawing accuracy.

[0035] The left side surface of the limit block 8 is connected and fixed to the side surface of the upper step 4, the lower end surface is arranged on the upper end surface of the lower step 5, and the right end surface is connected and fixed to the fixed pressing block 9 on the special-shaped pressing block. The movable pressing block 10 on the special-shaped pressing block is connected to the telescopic end of the horizontally placed first pressing cylinder 12, and the fixed end of the first pressing cylinder 12 is fixed to the sawing machine table 2 through the first buckle 14.

[0036] The first buckle 14 is a U-shaped buckle, and is disposed on the upper end surface of the lower step 5 .

[0037] The movable pressing block 10 can reciprocate on the upper end surface of the lower step 5 of the sawing machine table 2 as the telescopic end of the first pressing cylinder 12 is extended and retracted, thereby facilitating the pressing and loosening of the side surface of the profile 17.

[0038] A second buckle 15 is arranged on the end surface where the upper step 4 of the sawing machine table 2 connects with the upper end surface of the lower step 5. The second buckle 15 is also a U-shaped buckle. A longitudinally placed second clamping cylinder 13 is arranged in the second buckle 15. A cylindrical clamping block 16 is arranged at the telescopic end of the second clamping cylinder 13. The cylindrical clamping block 16 approaches the upper end surface of the profile placement cavity 11 as the telescopic end of the second clamping cylinder 13 extends, thereby clamping the profile 17 in the profile placement cavity 11. As the telescopic end of the second clamping cylinder 13 contracts, it moves away from the upper end surface of the profile placement cavity 11, thereby loosening the profile 17 in the profile placement cavity 11.

[0039] Two horizontal and vertical clamping cylinders are designed to fix the profile 17 and improve the stability of the profile 17. The two cylinders are used to achieve rapid clamping, which can improve production efficiency.

[0040] The limiting blocks 8 , the special-shaped pressing blocks and the L-shaped through holes 6 on the two sawing machine tables 2 are symmetrically arranged.

[0041] The process of using the overall technical solution formed by the above embodiments is as follows: the distance between the two sawing machine tables 2 is adjusted according to the length of the profile 17 to be sawed, and then the two ends of the profile 17 are placed in the profile placement cavity 11 on the two sawing machine tables 2 respectively. Note that the placement surface of the profile 17 must match the shape of the profile placement cavity 11, and then the first clamping cylinder 12 is adjusted to extend the telescopic rod of the first clamping cylinder 12, and the mobile clamping block 10 thereon is pushed close to the profile 17 until the profile is clamped. 17; then adjust the second clamping cylinder 13 to extend the telescopic rod of the second clamping cylinder 13, push the cylindrical clamping block 16 thereon close to the profile 17, until the profile 17 is clamped. After the profile 17 is fixed, start the saw blade 7 switch to move the saw blade 7 in the L-shaped through hole 6 to cut the profile 17. After cutting, adjust the first clamping cylinder 12 and the second clamping cylinder 13 to shrink the telescopic ends thereon, release the profile 17, and finally remove the cut profile 17 from the sawing table 2.

[0042] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
