[0003] The cut and formed saw blade blanks are transported to the quenching process area for quenching after tooth cutting. During the quenching process, the tooth edges of the saw blade need to be straightened, which requires the overall position of the saw blade when it is transmitted to the quenching station. Traditional processing equipment lacks the function of automatic position adjustment before transporting the saw blade to the quenching process, and relies on manual pre-combing, which is inefficient. Summary of the Invention

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] Example 1

[0027] A saw blade quenching device has three steps: material guiding, combing, and quenching;

[0028] The material guiding steps are as follows:

[0029] like Figure 1 、 Figure 2 、 Figure 3 As shown, the material guide assembly includes a conveyor belt 1 tilted to the left, with an inclination angle of 30°-45°. Side plates 11 are installed on both sides of the conveyor belt 1. A guide plate 12 is fixed to the rear end of the right side plate 11. The guide plate 12 tilts toward the left and moves closer to form a discharge port between the guide plate 12 and the side plate 11.

[0030] A plurality of material rollers 13 are arranged and rotatably mounted between the side plates 11. The material rollers 13 are connected to the conveyor belt 1 via a belt drive. The gap between the material rollers 13 arranged from front to back and the conveyor belt 1 gradually decreases. A pressure wheel 14 is rotatably mounted at the discharge port. The pressure wheel 14 is connected to the rotating shaft of the conveyor belt 1 via a gear drive. The pressure wheel 14 is made of rubber. The gap between the pressure wheel 14 and the conveyor belt 1 is smaller than the thickness of the saw blade.

[0031] Place the toothed saw blade at the front end of the conveyor belt 1, turn on the conveyor belt 1 to transport the saw blade backward, and the material roller 13 is driven to rotate by the conveyor belt 1. The saw blade passes through the material rollers 13 to block and comb, and the stacking height gradually decreases until the saw blade is combed into a single layer and laid flat on the surface of the conveyor belt 1. In the process of the material roller 13 pushing the saw blade, the saw blade is affected by the inclination of the conveyor belt 1 and approaches the left side plate 11. The saw blade is guided by the guide plate 12 to reach the discharge port one by one. The saw blade at the discharge port is kept in a single straight line state and discharged through the clamping of the pressure wheel 14 and the conveyor belt 1.

[0032] The steps for combing are as follows:

[0033] like Figure 4 、 Figure 5 As shown, the combing assembly 2 is arranged at the rear end of the conveyor belt 1, and the combing assembly 2 includes an inclined material tray 22, which is parallel to the conveyor belt 1, and the material tray 22 rotates around the pillow block 21. A drive motor 27 is installed on the surface of the pillow block 21, and the output shaft of the drive motor 27 is fixed with a gear. A gear ring is provided at the bottom of the material tray 22, and the drive motor 27 is connected to the drive material tray 22 through the gear and the gear ring. Six material troughs 23 are provided at equal angles on the upper surface of the material tray 22, and a cross groove 24 is provided on the upper surface of the pillow block 21. The cross groove 24 is aligned with the four material troughs 23 distributed at the right inclined top and the left inclined bottom of the material tray 22. Tooth grooves 26 are provided on both sides of each material trough 23, and a micro switch 25 is installed at the position of the discharge port on the surface of the pillow block 21. The micro switch 25 is electrically connected to the drive motor 27 through the controller;

[0034] The saw blade discharged from the discharge port is inserted into the material trough 23 at the front of the material tray 22. When the saw blade touches the microswitch 25, the controller controls the drive motor 27 to drive the material tray 22 to rotate 60°. The material trough 23 with the saw blade rotates to the right to above the inclined surface of the material tray 22. The saw blade is tilted and close to the front side of the material trough 23. If the smooth side of the saw blade is forward at this time, the saw blade is directly tilted to penetrate the cross groove 24 and the corresponding material trough 23 and slide out. If the saw teeth of the saw blade are located on the front side at this time, the saw blade cannot slide because the saw teeth are hooked with the tooth grooves 26. When the material tray 22 rotates 60° again, the saw blade moves to the rear position of the inclined top of the material tray 22. The smooth edge of the saw blade is tilted and close to the rear side of the material trough 23. The saw blade is tilted to penetrate the cross groove 24 and the corresponding material trough 23 and slide out, ensuring that the saw teeth side of the tilted saw blade is biased upward.

[0035] The quenching steps are as follows:

[0036] like Figure 6 、 Figure 7 As shown, a slide plate 3 extending parallel and obliquely to the left is provided at the lower part of the leftmost end of the material tray 22, and the quenching assembly includes a guide rail groove 4. The cross-section of the guide rail groove 4 is U-shaped. The bottom end of the slide plate 3 is connected to the right top of the guide rail groove 4. The left top height of the guide rail groove 4 is higher than the bottom end height of the slide plate 3. A guide wheel 6 is arranged and rotatably installed on the side of the guide rail groove 4. The guide wheel 6 penetrates into the guide rail groove 4. The guide wheel 6 is connected to a motor through a belt drive. An electromagnetic heating coil 5 is provided on the side of the guide rail groove 4.

[0037] The saw blade that slides out of the material trough 23 continues to slide down along the slide plate 3. Since the saw blade maintains the saw teeth tilted upward during the sliding process, the bottom of the saw blade contacts the left side of the guide rail groove 4, so that the saw blade is gradually adjusted to the right position, and the smooth edge of the saw blade slides down into the guide rail groove 4, with the sawtooth edge of the saw blade facing upward. The guide wheel 6 is driven by the motor to rotate, and the guide wheel 6 conveys the saw blade forward to move in the guide rail groove 4. The saw blade is quickly heated by the electromagnetic heating coil 5. After the saw blade is discharged from the guide rail groove 4, a specific temperature reduction is implemented to complete the quenching process of the saw blade.
