[0002] A band saw blade consists of a tough, sharp-toothed saw blade stretched in a frame and is used for cutting wood and other shaped materials.

[0003] The tension processing of a band saw blade refers to the process of stretching the middle portion of the saw blade by rolling, causing it to deform, thereby increasing the working strength of the saw tooth portion of the saw blade and making the cutting section straight, thereby increasing the rigidity and service life of the saw blade. In the prior art, most tension processing devices are unable to adjust the rolling force during use, thereby being unable to adjust the tension processing force, and are insufficiently practical. Therefore, it is necessary to redesign a saw blade tension control device for mechanical saw processing in response to the above-mentioned problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A saw blade tension control device for mechanical saw processing includes a processing table 1, a pressure detector 2 is fixedly installed on the upper end surface of the processing table 1, and a placement plate 4 is fixedly connected to the upper end surface of the pressure detector 2 through a supporting mechanism. The supporting mechanism includes a plurality of support rods 3 fixedly installed on the upper end surface of the pressure detector 2, and each end of the support rod 3 is fixedly connected to the bottom wall of the placement plate 4. A plurality of baffles 5 cooperating with the placement plate 4 are fixedly installed on the upper end surface of the processing table 1, and a moving frame 6 is fixedly installed on the upper end surface of the processing table 1. A screw rod 7 is rotatably installed inside the moving frame 6, and a first motor 8 cooperating with the screw rod 7 is fixedly installed on the outer wall of the moving frame 6. A moving block 10 is threadedly installed on the outer wall of the screw rod 7 through a limiting mechanism. The limiting mechanism includes a limiting rod 9 fixedly installed inside the moving frame 6, and the limiting rod 9 slides through the moving block 10. The limiting rod 9 can limit the moving block 10 so that it can only move axially along the outer wall of the screw rod 7.

[0023] A support frame 11 is fixed to the end of the moving block 10, a cylinder 12 is fixedly installed on the top wall of the support frame 11, a lower pressing frame 13 is fixedly connected to the telescopic end of the cylinder 12, a lower pressing roller 14 is rotatably installed inside the lower pressing frame 13, a connecting frame 15 is fixedly installed on the upper end surface of the processing table 1, a rotating shaft 16 is rotatably installed inside the connecting frame 15, a second motor 17 connected to the rotating shaft 16 is fixedly installed on the upper end surface of the connecting frame 15, a connecting sleeve 18 is fixedly installed on the outer wall of the rotating shaft 16, a connecting rod 19 is fixedly installed on the outer wall of the connecting sleeve 18, and a high-temperature heating plate 20 is fixedly connected to the end of the connecting rod 19.

[0024] When the utility model is used, the saw blade is first placed on the upper end surface of the placement plate 4, and then the second motor 17 can drive the rotating shaft 16 to rotate, and the rotating shaft 16 then drives the high-temperature heating plate 20 to rotate through the cooperation of the connecting sleeve 18 and the connecting rod 19, so that it rotates above the saw blade, thereby allowing the high-temperature heating plate 20 to heat the saw blade. When the saw blade is heated, the second motor 17 can drive the rotating shaft 16 to reverse, thereby driving the high-temperature heating plate 20 to rotate and move out from above the saw blade, and then the cylinder 12 can drive the lower pressing frame 13 to move, so that the lower pressing frame 13 drives the lower pressing roller 14 to squeeze the surface of the saw blade, and the placement plate 4 can transmit the squeezing force to the pressure detector 2 through the cooperation of the support rod 3. At this time, the pressure detector 2 can monitor the squeezing force applied by the lower pressing roller 14, and the squeezing force can be adjusted by the extension and contraction of the cylinder 12, thereby realizing the control of the appropriate tension of the saw blade;

[0025] At the same time, the first motor 8 drives the screw 7 to rotate, and the screw 7 drives the moving block 10 to move by cooperating with the limit rod 9. The moving block 10 then drives the support frame 11 to move, thereby driving the lower pressure roller 14 to move and roll the surface of the saw blade, thereby realizing the extension and deformation of the saw blade. In the process of extension and deformation of the saw blade, the cooperation of multiple baffles 5 can limit the saw blade, avoid its displacement and deviation during the rolling process, and prevent it from falling from the upper end surface of the placement plate 4.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
