Description

Technical Field

[0001] The utility model belongs to the technical field of gear dividing machines, in particular to a small-tooth band saw blade gear dividing machine. Background Art

[0002] Band saw blade toothing machine is a kind of equipment specially used for processing the tooth shape of band saw blade. Band saw blade is a kind of ring-shaped saw blade used for cutting operation on band saw machine. In order to ensure the cutting performance and service life of band saw blade, its tooth shape needs to be processed accurately.

[0003] Conventional bimetallic band saw blade tooth-splitting machines are made according to the different tooth types of the saw band. Each tooth-splitting collision tooth needs to be ground separately and finally assembled. The processing is complicated and the precision requirements are high. For too fine saw teeth, the tooth-splitting mold cannot even be made. Because the transmission chains of the existing tooth-splitting machines are mechanically linked, the processing and assembly are often prone to accumulated transmission errors, resulting in inaccurate tooth-splitting. In addition, the existing tooth-splitting structure is mechanically linked, and the accumulated errors in the transmission process are transmitted to the tooth-splitting, which is very easy to mis-pick the specified saw teeth, causing the feeding teeth to be misplaced, resulting in poor tooth-splitting or even damage to the saw blade.

[0050] In the description of the present invention, it should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present application. For the convenience of description, the dimensions of each part shown in the drawings are not drawn in actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technologies, methods, and devices should be regarded as a part of the authorization specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0051] Before the band saw blade is tooth-divided by a tooth-dividing machine, the tooth tips extend in the width direction of the band saw blade. As shown in the structure on the left side of Figure 9 At this time, it is also called the workpiece band saw blade 100. The workpiece band saw blade 100 cannot be used in a band sawing machine for metal cutting. After being tooth-divided by a tooth-dividing machine, its tooth tips are inclined at a certain angle with respect to the length direction of the band saw blade. As shown in Figure 9As shown by the structure on the right side in the figure, at this time, it is also called the product band saw blade 200. When the product band saw blade 200 moves into the band sawing machine, driven by the band sawing machine, the band saw blade moves along the length direction to cut metal.

[0052] Embodiment 1

[0053] This embodiment provides a small tooth type band saw blade tooth dividing machine, including: a workbench 1, a servo tooth dividing part 2, and a servo tooth shifting part 3.

[0054] The workbench 1 is used to carry each functional part.

[0055] Please refer to Figure 1 , the servo tooth dividing part 2 includes a front tooth dividing die 201 and a rear tooth dividing die 202. The front tooth dividing die 201 and the rear tooth dividing die 202 are respectively located on the front and rear sides of the workbench 1. The front tooth dividing die 201 is fixed on the front tooth dividing slider, and the rear tooth dividing die 202 is fixed on the rear tooth dividing slider. The front tooth dividing slider and the rear tooth dividing slider are respectively driven by a combination of two servo motors + linear electric cylinders to slide on the workbench 1. The front tooth dividing die 201 and the rear tooth dividing die 202 approach and impact the workpiece band saw blade 100 and move away from the workpiece band saw blade 100 under the movement of the front tooth dividing slider and the rear tooth dividing slider, so as to perform tooth profile processing on a group of teeth on the workpiece band saw blade 100. Here, a group of teeth can be understood as multiple teeth on the workpiece band saw blade 100 located between the front tooth dividing die 201 and the rear tooth dividing die 202.

[0056] The servo tooth shifting part 3 includes a linear module 301 and a pawl 302. The linear module 301 is precisely controlled by a servo motor. The pawl 302 can contact and separate from the workpiece band saw blade 100 by swinging up and down. The linear module 301 can drive the pawl 302 to move linearly. Specifically, when the pawl 302 swings downward, it can extend into the space between two adjacent teeth on the workpiece band saw blade 100. In this way, when the linear module 301 drives the pawl 302 to move linearly, the pawl 302 can push the workpiece band saw blade 100. When the workpiece band saw blade 100 is pushed to a suitable position, the pawl 302 swings upward to separate from the band saw blade. At this time, the linear module 301 drives the pawl 302 to move linearly and reset.

[0057] Please refer to Figure 6 , a fixed frame 303 is provided on the workbench 1. One end of a swing fork 304 is rotatably connected to the fixed frame 303. The pawl 302 is connected to the linear module 301 through an adjustment frame 305. One end of the pawl 302 is rotatably connected to the adjustment frame 305 through a rotating shaft 306. The outer peripheral wall of the end of the rotating shaft 306 has an arc section and a straight section. A linkage groove is provided at the free end of the swing fork 304. The end of the rotating shaft 306 is slidably arranged in the linkage groove, and the end of the rotating shaft 306 can only slide relative to the linkage groove and cannot rotate relative to the linkage groove. Please refer to Figure 5, the rotating shaft 306 is integrally Z-shaped. The section of the rotating shaft 306 connected to the pawl 302 and the section of the rotating shaft 306 connected to the linkage groove are not collinear. During the process of being driven by the linear module 301, the pawl 302 will drive the free end of the swing fork 304 to swing through the rotating shaft 306. During the swinging process of the free end of the swing fork 304, it will drive the rotating shaft 306 to rotate, thereby driving the pawl 302 to swing. In this way, when the pawl 302 is in the initial position, the pawl 302 is at the highest point on the swinging track. During the process of the linear module 301 driving the pawl 302 to move linearly to push the workpiece band saw blade 100, the cooperation between the rotating shaft 306 and the swing fork 304 causes the pawl 302 to continuously swing downward and approach the workpiece band saw blade 100. During the process of the linear module 301 driving the pawl 302 to reset, the cooperation between the rotating shaft 306 and the swing fork 304 causes the pawl 302 to continuously swing upward and move away from the workpiece band saw blade 100.

[0058] In this embodiment, a control panel 8 is provided on the workbench 1. The operator can input the required values through the control panel 8 to control each servo motor, thereby controlling the length of each tooth pushing of the workpiece band saw blade 100 by the servo tooth pushing part 3 and the tooth dividing amount of the servo tooth dividing part 2.

[0059] In this embodiment, the linear module 301 controlled by the servo motor cooperates with the pawl 302 to push a section of the band saw blade between the front tooth dividing die 201 and the rear tooth dividing die 202 each time. The front tooth dividing die 201 and the rear tooth dividing die 202 controlled by the servo motor and the linear electric cylinder move towards each other to impact the band saw blade, and at the same time perform tooth profile processing on a group of multiple teeth located at the servo tooth dividing part 2 of the band saw blade. After the processing is completed, the front tooth dividing die 201 and the rear tooth dividing die 202 move away from each other. The linear module 301 and the pawl 302 cooperate to push the subsequent section of the band saw blade between the front tooth dividing die 201 and the rear tooth dividing die 202, and perform tooth profile processing again. In this way, the tooth profile processing of the entire band saw blade is completed repeatedly.

[0060] The tooth dividing machine of this embodiment adopts full servo control, with accurate feeding, not easy to misplace the saw teeth. The front tooth dividing die 201 and the rear tooth dividing die 202 can be independently controlled, and the tooth dividing amount on each side can be set by inputting corresponding values through the control panel 8.
