[0003] In the manufacturing process of screwdrivers, the cutting device is one of the key processing equipment, and its performance directly affects the manufacturing efficiency and product quality of the screwdriver. At present, most of the common screwdriver manufacturing cutting devices on the market adopt the traditional mechanical cutting method. Although it can achieve basic cutting functions, the screwdriver head structure is usually composed of a steel structure, and the cutting knife structure of the traditional cutting device can often only be used for continuous cutting of a group of steel wire raw materials, and the steel wire raw materials are required to have a high continuity. It is not convenient to continuously cut and adjust the existing multiple sections of steel wire raw materials. In addition, during the continuous cutting process, the cutting knife structure of the traditional cutting device can often only cut a single length. Although it has a high work efficiency, it is limited by its integrated production line equipment. In order to facilitate the subsequent processing of the screwdriver head raw materials, the overall structural design of the cutting knife of the cutting device is usually simpler and the function is relatively single. If it is only for the cutting process of the screwdriver raw materials, the traditional cutting device also has certain limitations during use. Utility Model Content

The cutting knife 1 is rotatably provided on the second connecting seat 1012 and is driven to rotate by a fourth driving component 114 provided on the second connecting seat 1012. A base 2 for fixing a plurality of steel wire 110 raw materials is provided on the second frame 102 and is placed below the first frame 101.

[0024] Specifically in this embodiment, the overall structure of this cutting device can be seen in Figure 1As shown, the base 2 can be fixed with multiple sections of steel wire 110 with different redundant lengths and other raw materials for manufacturing screwdriver blades. After the multiple sections of steel wire 110 are fixed on the base 2, the cutting device starts to work. The second frame 102 and the first frame 101, the first frame 101 and the first connecting seat 1011, and the first connecting seat 1011 and the second connecting seat 1012 are respectively slid to corresponding positions through the slide rails 120 and the adapter slider 121 provided thereon, and the first driving component 111 on the second frame 102 drives the cutting blade 1 on the first frame 101 and the second connecting seat 1012 to move forward and backward along the fixing direction of the steel wire 110 on the base 2 of the second frame 102. The sliding on the device, by controlling the start and stop of the first driving component 111, the movement process of the second frame 102 at different positions is realized, so that the steel wire 110 of different lengths is cut. At the same time, in the process of adjusting the specific cutting length according to the use requirements, the third driving component 113 on the first connecting seat 1011 drives the second connecting seat 1012 to move left and right on the slide rail 120 on the first connecting seat 1011 along the arrangement direction of the multiple sections of steel wire 110 on the base 2, thereby driving the cutting knife 1 and the fourth driving component 114 on the second connecting seat 1012 to move to different positions and place them at the specific cutting position of the steel wire 110 to be cut. After the position adjustment of the cutting knife 1 is completed, the The fourth driving component 114 on the second connecting seat 1012 starts to drive the cutting knife 1 to rotate. While the cutting knife 1 rotates, the second driving component 112 on the first frame 101 can drive the first connecting seat 1011 and the second connecting seat 1012 to slide up and down along the direction of the slide rail 120 on the first frame 101, thereby driving the cutting knife 1 on the second connecting seat 1012 to move up and down to realize the cutting process of the steel wire 110 at the cutting position. Specifically, during the cutting process, the third driving component 113 on the first connecting seat 1011 can repeat the above working process according to the specific cutting situation and cutting requirements. The first driving component 111, the second driving component 112, and the third driving component 113 provided on the cutting device The driving component 113 and the fourth driving component 114 are both connected to the controller provided on their signal lines, so that the setting of this tool holder 100 structure can realize automatic cutting according to specific cutting requirements compared to the tool holder 100 structure of the traditional cutting device, and can continuously cut the multiple sections of steel wire 110 fixed on the base 2, and can also facilitate the cutting process of different lengths at different cutting positions, and is not affected by the specific length of the raw material of the steel wire 110. It is convenient to operate and is aimed at the specific cutting process in the screwdriver manufacturing process. It can meet different cutting requirements and has a higher cutting efficiency, and realizes the storage of screwdriver blades in batches and of different lengths, thereby facilitating the subsequent process.

[0025] The second driving component 112 and the third driving component 113 are both driven by ball screws, and the second driving motor and the third driving motor arranged thereon respectively drive the first screw shaft 1121 and the second screw shaft adapted to rotate at the corresponding positions of the first frame 101 and the first connecting seat 1011 through the synchronous belt 122 structure. Figure 1-2 As shown in the figure, the second drive component 112 and the third drive component 113 driven by the ball screw drive method have higher transmission efficiency and transmission accuracy, further reducing the unnecessary influence of the vibration or position offset of the first connecting seat 1011 and the second connecting seat 1012 during the transmission process on the cutting position, further improving the cutting accuracy and cutting effect. In addition, the second drive motor and the third drive motor respectively drive the matching first screw shaft 1121 and the second screw shaft through the synchronous belt 122 structure. This indirect driving method can avoid the damage to the drive motor caused by direct drive due to a certain load formed during the cutting process, thereby further improving the working stability of the drive motor during the cutting process, and appropriately extending the service life, and further reducing the use and maintenance costs.

[0026] The first driving component 111 disposed on the second frame 102 and the fourth driving component 114 disposed on the second connecting seat 1012 are both driven by a synchronous belt 122, and the first driving motor and the fourth driving motor disposed thereon are respectively connected by the synchronous belt 122 structure and drive the first frame 101 to slide on the second frame 102 and the cutting knife 1 to rotate on the second connecting seat 1012. Figure 2 As shown in the figure, the slider 121 on the first frame 101 is installed on the synchronous belt 122 connected to the first drive motor on the second frame 102, so that the first frame 101 is driven by the first drive motor to slide on the slide rail 120 of the second frame 102, and the transmission is more stable. Figure 3 The fourth drive motor is connected through a synchronous belt 122 structure and drives the cutting knife 1 on the second connecting seat 1012 to rotate. Compared with the traditional direct drive method, this indirect drive method can reduce the load and impact generated by the cutting knife 1 on the fourth drive motor during the cutting process and play a certain protective role, thereby improving the operating stability and extending the service life.

The baffle 21 and the support 22 on the base 2 respectively arranged at the two end points of the scale line 1021 are convenient for the installation and fixation of the multiple sections of steel wire 110. The setting of the baffle 21 can avoid the displacement of the steel wire 110 during the cutting process. The setting of the multiple groups of supports 22 can facilitate the support and fixation of the multiple sections of steel wire 110 and avoid the position deviation of the steel wire 110 during the cutting process, thereby further improving the cutting stability.

[0029] The first frame 101 is also provided with a slide 1014, which is placed on one side of the cutting blade 1 and has a plurality of through holes 10141 adapted to the sizes of the plurality of steel wires 110. Figure 6 As shown in the figure, a plurality of sections of steel wire 110 can be passed through the through hole 10141 of the slide 1014. In the process of the first frame 101 driving the cutting knife 1 to move, the slide 1014 on one side of the cutting knife 1 can be driven to slide on the plurality of sections of steel wire 110 fixed on the base 2. The slide 1014 disposed on one side of the cutting knife 1 can provide a certain support for the steel wire 110 at a specific cutting position, so that the steel wire 110 has a certain stability during the cutting process, thereby ensuring the stable cutting process of the cutting knife 1 and reducing the influence of the bending deformation or position displacement of the steel wire 110 during the cutting process on the cutting effect at the cutting position.

[0030] The outer periphery of the cutting knife 1 is also covered with an adaptive protective cover 11, and the protective cover 11 is installed on the second connecting seat 1012 through a detachable structure. Figure 7As shown, the protective cover 11 provides a certain degree of protection for the cutting knife 1 and can reduce the damage caused to the cutting knife 1 and even the rotating shaft by splashing waste residue during the cutting process. At the same time, the protective cover 11 is installed on the second connecting seat 1012 by bolts, which facilitates the installation, disassembly and replacement of the protective cover 11 and the cutting knife 1.
