Description

Technical Field

[0001] The utility model relates to the technical field related to saw blade processing, in particular to an automatic flattening machine for quenching saw blades. Background Art

[0002] After the blank saw blade is heated and quenched in a heating furnace, its internal structure changes due to thermal expansion and contraction, which can cause large deformation and distortion. The existing method to solve the deformation and distortion of the blank saw blade is as follows: after the blank saw blade is output through the conveying device in the quenching oil pool, a worker uses a clamp to clamp the quenched blank saw blade and places it between the upper pressure block and the lower pressure block on the flattening device, and then manually presses the start button on the flattening device. The hydraulic cylinder on the flattening device drives the upper pressure block to move downward and cooperate with the lower pressure block to clamp the blank saw blade for a few seconds to flatten the blank saw blade. After flattening, another worker takes the blank saw blade away, processing one or two blank saw blades at a time, resulting in low leveling efficiency and low output after quenching, which cannot meet the production needs of the company. Utility Model Content

[0003] In order to overcome the existing technical defects and solve the technical problem of low leveling efficiency of the existing rough saw blade after quenching, the purpose of the utility model is to provide a saw blade quenching automatic flattening machine to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] According to one aspect of the utility model, a saw blade quenching automatic flattening machine is designed, comprising: a frame, a first driving shaft, a second driving shaft, a first driven shaft, a second driven shaft, a first conveyor mesh belt, a second conveyor mesh belt, a first driving device and a second driving device, the first driving shaft and the second driving shaft are rotatably connected to the left end of the frame, the first driven shaft and the second driven shaft are rotatably connected to the right end of the frame, the left end of the first conveyor mesh belt cooperates with the sprocket connected to the first driving shaft, and the right end cooperates with the sprocket connected to the first driven shaft, the first driving device cooperates with the first A driving shaft is connected to drive the first driving shaft to rotate and link the first conveyor mesh belt to rotate counterclockwise. The second conveyor mesh belt is arranged above the first conveyor mesh belt. The left end of the second conveyor mesh belt cooperates with the sprocket connected to the second driving shaft, and the right end cooperates with the sprocket connected to the second driven shaft. The second driving device is connected to the second driving shaft to drive the second driving shaft to rotate and link the second conveyor mesh belt to rotate clockwise. The counterclockwise rotation of the first conveyor mesh belt and the clockwise rotation of the second conveyor mesh belt can press and level the blank saw blade transported between the two.

[0006] By adopting the above technical scheme, the right end of the automatic flattening machine for saw blade quenching is the feeding end, and the left end is the discharging end. When in use, it is connected to the output end of the conveying device in the quenching oil pool to receive the blank saw blade outputted by it. When the equipment is started, the first driving device drives the first active shaft to rotate and links the first conveyor mesh belt to rotate counterclockwise, and the second driving device drives the second active shaft to rotate and links the second conveyor mesh belt to rotate clockwise. When the blank saw blade enters from the feeding end to between the first conveyor mesh belt and the second conveyor mesh belt and is transported to the left, the blank saw blade can be pressed and flattened by the first conveyor mesh belt and the second conveyor mesh belt. Since the equipment runs continuously, the blank saw blade can be continuously pressed and flattened. Compared with the existing pressing and flattening of the blank saw blade by a flattening device, the pressing and flattening of the blank saw blade is realized continuously and automatically, which greatly improves the flattening efficiency of the blank saw blade, can meet the production needs of the enterprise, and can reduce labor and reduce labor costs.
