[0002] Saw blade refers to a tool used for cutting materials, usually made of metal with serrations on the edge. There are many types of saw blades, including circular saw blades, band saw blades, curved saw blades, saw blades and special saw blades. During processing, the saw blade shape needs to be initially formed from the base material by stamping or laser cutting, and then heat treated to increase its hardness and wear resistance. Depending on the purpose of use, it is possible to choose whether to weld the teeth or bend the teeth. After dynamic balancing testing, it can be shipped from the factory.

[0003] The existing sawtooth bending process adopts hydraulic or electric drive, and uses a scissor-type impact arm to stamp and bend the sawtooth.

The output end of the motor 21 is connected to the driving shaft 22. The driving shaft 22 is provided with two eccentric hinge shafts 1 221 and an eccentric hinge shaft 2 222. The stamping column 1 25 and the stamping column 2 26 are slidably arranged in the base 1. Two corner columns 251 are symmetrically arranged on the stamping column 1 25. A hinge rod 1 23 is hingedly connected between the corner column 251 and the eccentric hinge shaft 1 221. A hinge rod 24 is hingedly connected between the eccentric hinge shaft 222 and the stamping column 2 26. Buffer pads 27 are provided at the ends of the stamping column 1 25 and the stamping column 2 26.

[0032] Working principle of driving mechanism 2: motor 21 drives driving shaft 22 to rotate, so that eccentric hinged shaft 1 221 and eccentric hinged shaft 2 222 rotate around the axis of driving shaft 22, eccentric hinged shaft 1 221 drives stamping column 1 25 to slide in base 1 through hinged rod 1 23, eccentric hinged shaft 2 222 drives stamping column 2 26 to slide in base 1 through hinged rod 24, stamping column 1 25 and stamping column 2 26 move in opposite directions, and stamping bending mechanism 3 is driven by transmission rod 1 252 and transmission rod 2 261 to bend the saw teeth, and intermittent transmission mechanism 5 is driven by sliding sleeve 253 on the rear side of stamping column 1 25, and intermittent rotation mechanism 7 is driven by groove wheel 1 223. When stamping column 1 25 and stamping column 2 26 move toward each other, the buffer pad 27 at their ends is used to reduce shock.

[0033] Combined with Figure 1 , Attachment Figure 6 , Attachment Figure 7 and attached Fig. 9 As shown, the stamping and bending mechanism 3 includes two symmetrically arranged pressing plates 31, and a stamping head 34 is hingedly provided on each of the pressing plates 31. A transmission rod 1 252 and a transmission rod 261 are respectively provided on one side of the stamping column 1 25 and the stamping column 26. The transmission rod 1 252 and the transmission rod 261 are respectively hinged with the two stamping heads 34. The clamping mechanism 4 includes a cylinder 1 41, a moving platform 42 and a fixed platform 43. The cylinder 1 41 is fixed on the supporting platform 13 on the base 1, and the output end of the cylinder 1 41 is connected to the moving platform 42. The movable platform 42 is slidably arranged in the groove on the support platform 13, and the fixed platform 43 is fixedly arranged on the support plate 14 on the base 1. The movable platform 42 and the fixed platform 43 are respectively provided with a wing plate 1 421 and a wing plate 2 431 on the side close to the stamping and bending mechanism 3. A sliding column 32 is provided at the rear end of the pressure plate 31. The sliding columns 32 on the two pressure plates 31 respectively pass through the through holes on the wing plate 1 421 and the wing plate 2 431. A spring 33 is provided on the outer side of the sliding column 32. A plurality of ball grooves are provided on the inner side of the pressure plate 31. Balls 35 are provided to rotate in the ball grooves.

[0034] The working principle of the stamping and bending mechanism 3 and the clamping mechanism 4 is as follows: the cylinder 1 41 drives the moving platform 42 to move in the inner groove of the support platform 13, so that the pressure plate 31 on the wing plate 1 421 and the wing plate 2 431 clamps the circular saw blade or the long saw blade, and the ball 35 on the pressure plate 31 contacts the saw blade. During stamping, the two stamping heads 34 on both sides of the saw blade are driven to move through the transmission rod 1 252 and the transmission rod 2 261. The stamping head 34 first fits the side of the saw tooth, and then the stamping head 34 presses against the saw tooth to bend the two adjacent saw teeth. In the latter stage of bending, the rotation axis of the stamping head 34 is not in the stamping position. The hinge axis of the punch head 34 and the pressure plate 31, the reaction force of the saw teeth on the punch head 34 will push the pressure plate 31 to move a certain distance toward the wing plate 1 421 or the wing plate 2 431, compressing the spring 33, so that the rotation axis of the punch head 34 is close to the bending line of the saw teeth, so that during the bending process of the saw teeth by the punch head 34, the inner side surface of the punch head 34 is in contact with the saw teeth, so that the bending line of the saw teeth is away from the tooth angle of the saw teeth, preventing the tooth angle from breaking and the saw teeth from bending. After the punch head 34 is reset, the circular saw blade rotates or the long saw blade moves horizontally, and the pressure plate 31 can be kept in the clamping position through the rolling of the ball 35.

[0035] Combined with Figure 1 , Attachment Figure 3 , Attachment Fig.10 , Attachment Fig.11 and attached Fig.12 As shown, the intermittent transmission mechanism 5 includes a cylinder 2 51 and a transmission member 52. The two groups of transmission members 52 are mirror-symmetrical. The transmission member 52 includes a gear 1 521, a half gear 524 and a gear 2 526. A connecting shaft 522 is provided at the bottom of the gear 1 521. A linkage plate 511 is provided at the output end of the cylinder 2 51. The two connecting shafts 522 are rotatably arranged at the two ends of the top of the linkage plate 511. A spline shaft 1 523 is provided at the top of the gear 1 521. A spline groove 1 525 matching the spline shaft 1 523 is provided at the axis center of the half gear 524. The gear 1 521 is meshed with the gear 2 526. The intermittent transmission mechanism 5 also includes two groups of symmetrically arranged turntables 53 and slide bars 54. The turntable 53 is rotatably arranged at In the base 1, a sliding sleeve 253 is provided at the rear end of the stamping column 25, and two sliding rods 54 are slidably arranged in the sliding sleeve 253. A rack 541 is provided at the end of the sliding rod 54, and the rack 541 is meshed with the gear 2 526. The bottom boss of the rack 541 is rotatably connected with the eccentric shaft 531 at the top of the turntable 53. The conveying mechanism 6 includes two groups of symmetrically arranged conveying belts 61, and rotating shafts 62 are provided at both ends of the conveying belts 61. The rotating shafts 62 are rotatably arranged on the guard plates 12 on both sides of the feed trough 11.

One of the gears 3 63 is coaxially connected with a gear 4 64, and the gear 4 64 is meshed with the half gear 524.

[0036] Working principle of the intermittent transmission mechanism 5 and the conveying mechanism 6: When bending the teeth of the long saw blade, the movement of the punching column 25 drives the two slide bars 54 to move along with the punching column 25 through the sliding sleeve 253. Since the bottom boss of the rack 541 at the end of the slide bar 54 is rotatably connected with the eccentric shaft 531 at the top of the turntable 53, the forward and backward movement of the slide bar 54 drives the turntable 53 to rotate. The slide bar 54 slides left and right in the sliding sleeve 253, so that the rack 541 forms a circular motion posture, and the tooth surface of the rack 541 always faces the gear 2 526. After the rack 541 approaches the gear 2 526, the rack 541 meshes with the gear 2 526 for transmission, driving the gear 2 526 to rotate one circle, and the gear 1 521 meshes with the gear 2 526 for transmission, driving the gear 1 521 rotates, and the spline shaft 1 523 cooperates with the spline groove 1 525 to make the half gear 524 rotate one circle. When the teeth on the half gear 524 move to the gear 4 64, the driving gear 4 64 rotates a certain angle, so that the rotating shaft 62 rotates, and the gear 3 63 at the end of the rotating shaft 62 is engaged, so that the two conveyor belts 61 rotate in opposite directions and have the same conveying speed. The two conveyor belts 61 are clamped and convey the long saw blade for a certain distance, so that the long saw blade moves intermittently. When the saw teeth of the circular saw blade are bent, the cylinder 2 51 pushes the linkage plate 511 to move downward, and the connecting shaft 522 is driven downward by the linkage plate 511 to move the gear 1 521 downward, so that the gear 1 521 is disengaged from the gear 2 526, so that the movement of the stamping column 1 25 cannot drive the conveying mechanism 6.

[0037] Combined with Figure 1 , Attachment Figure 4 , Attachment Figure 5 , Attachment Fig.13 , Attachment Fig.14 and attached Fig.15 As shown, the intermittent rotation mechanism 7 includes a cylinder 3 71, a gear 5 72, a groove wheel 2 73, a gear 6 74, a driving platform 75 and a transmission plate 76.

A spline shaft 2 721 is provided at the top of the gear 5 72. The groove wheel 2 73 is rotatably arranged in the base 1. A groove wheel 1 223 is provided on the driving shaft 22, which is matched with the groove wheel 2 73 through a belt drive. A spline groove 2 731 is provided at the axis of the groove wheel 2 73, which is matched with the spline shaft 2 721. The gear 6 74 meshes with the gear 5 72. The gear 5 72 is coaxially connected to the driving platform 75, and a driving plate 751 is provided on the side of the driving platform 75. A plurality of inclined platforms 761 are obliquely provided on the rear side of the transmission disk 76. The driving plate 751 cooperates with the inclined surface of one side of the inclined platform 761. The transmission disk 76 is rotatably arranged on the moving platform 42. A clamping disk 1 762 coaxially connected to the transmission disk 76 is provided at the front end of the moving platform 42. A clamping disk 2 77 cooperating with the clamping disk 1 762 is rotatably provided on one side of the fixed platform 43. A positioning plug-in 763 is provided at the front end of the clamping disk 1 762. The positioning plug-in 763 is plugged into and cooperated with the through hole on one side of the clamping disk 2 77.

[0038] Working principle of intermittent rotation mechanism 7: when bending the teeth of the circular saw blade, the driving shaft 22 drives the groove wheel 1 223 to rotate, and the groove wheel 1 223 cooperates with the groove wheel 2 73 through belt transmission, driving the groove wheel 2 73 to rotate, and the spline groove 2 731 on the inner side of the groove wheel 2 73 cooperates with the spline shaft 2 721 to drive the gear 5 72 to rotate, and the gear 5 72 coaxially connected to the gear 5 72 rotates one circle, and the driving plate 751 rotates with the gear 5 72. When the driving plate 751 moves to the position of the inclined platform 761, the inclined surface of the driving plate 751 slides with the inclined surface of the inclined platform 761, driving the transmission disk 76 to rotate a certain angle, and the clamping disk 1 762 coaxially connected to the transmission disk 76 cooperates with the clamping disk 2 77 to drive the circular saw blade to rotate a certain angle.

[0039] In the specific implementation of the present invention, when bending the teeth of a long saw blade, the saw blade enters the conveying mechanism 6 between the guard plates 12 through the feed trough 11, and the stamping column 1 25 and the stamping column 2 26 are moved in opposite directions through the driving mechanism 2, and the saw teeth are bent in cooperation with the stamping and bending mechanism 3, and the intermittent transmission mechanism 5 is coupled with the conveying mechanism 6, and the power transmission between the driving mechanism 2 and the conveying mechanism 6 is realized through the intermittent transmission mechanism 5, so that the conveying mechanism 6 drives the saw blade to move in an intermittent motion manner, so that the long saw blade switches the saw teeth after the saw teeth are stamped and bent; When bending the saw teeth of the circular saw blade, the saw blade is placed between the clamping disk 1 762 and the clamping disk 2 77, and the clamping mechanism 4 clamps the saw blade between the clamping disk 1 762 and the clamping disk 2 77, the intermittent transmission mechanism 5 is decoupled from the conveying mechanism 6, and the intermittent rotation mechanism 7 is coupled with the driving mechanism 2, so that the driving mechanism 2 drives the saw blade to achieve intermittent rotation effect through the intermittent rotation mechanism 7, and the driving mechanism 2 drives the stamping and bending mechanism 3 to bend the saw teeth, so that the circular saw blade switches the saw teeth after the saw teeth are stamped and bent; When the saw teeth are bent, the punching column 1 25 and the punching column 2 26 move in opposite directions, driving the two punching heads 34 to move in opposite directions, so that the adjacent saw teeth are bent in two directions. During the bending process, the punching head 34 fits against the side of the saw teeth, and the pressure plate 31 moves a short distance, so that the rotation axis of the punching head 34 is close to the bending line of the saw teeth, thereby making the bending line of the saw teeth away from the tooth angle of the saw teeth, preventing the tooth angle from breaking and the saw teeth from bending.
