DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] refer to Figure 1-6 The stamping continuous die fixed number cutting mechanism comprises a base 1, a workbench 101 and a cutting device. The workbench 101 is arranged on the top of the base 1. A support plate 102 is fixedly connected to the top of the base 1. A telescopic driving mechanism 103 is arranged on the support plate 102. A stamping block 104 for stamping a material strip is connected to the output end of the telescopic driving mechanism 103. An adjusting block 105 is arranged on one side of the stamping block 104. A bottom plate 4 is arranged on one side of the stamping block 104. The bottom plate 4 is threadedly connected to the side of the stamping block 104 through a screw. The adjusting block 105 is arranged on the bottom plate 4. The bolt 401 connection can be disassembled by rotating and tightening or loosening the bolt 401, so that the maintenance and replacement of the adjusting block 105 becomes easier and more convenient. At the same time, the bolt 401 connection can provide a higher bearing capacity and can withstand the weight of the cutting device and the adjusting block 105.

[0026] An adjusting screw 106 is provided inside the adjusting block 105, and an adjusting slot 402 is provided inside the adjusting block 105. The adjusting screw 106 is arranged in the adjusting slot 402. One end of the adjusting screw 106 passes through the side of the adjusting block 105 and extends to the outside of the adjusting block 105. The cutting device is arranged inside the adjusting block 105 and is threadedly connected with the adjusting screw 106. When the staff needs to adjust the cutting constant of the stamping die, they only need to rotate the adjusting screw 106, and the adjusting screw 106 will drive the cutting device to move inside the adjusting block 105, so as to adjust the cutting constant, thereby improving practicality. Since the threaded connection is self-locking, the cutting device will not move at will. In order to improve the cutting stability of the cutting device, a reinforcing rod 5 is threadedly connected to the top of the adjusting block 105 through a bolt, and the other end of the reinforcing rod 5 is threadedly connected to the side of the stamping block 104. The reinforcing rod 5 can improve the stability of the cutting device during cutting.

[0027] In order to facilitate the staff to rotate the adjusting screw 106, a knob 107 is provided on the side of the adjusting screw 106 away from the adjusting block 105, and the outer surface of the knob 107 is provided with anti-slip texture. The knob 107 can help the staff to obtain a larger torque, which is convenient for the staff to rotate the adjusting screw 106, and the anti-slip texture can increase the contact area between the staff and the knob 107 and provide a better grip. Scale lines are provided on the side of the adjusting block 105 away from the adjusting screw 106. The scale lines can reduce the possibility of errors when the user adjusts the cutting constant. By using fixed scale lines as a reference, the staff can more easily maintain a consistent cutting size and reduce errors caused by human errors.

[0028] In this embodiment, the cutting device includes a cutting block 2, a cutting plate 201, and a cutting knife 202. The cutting block 2 is arranged inside the adjusting block 105 and is threadedly connected to the adjusting screw 106. The cutting block 2 is a rectangular parallelepiped structure. The cutting block 2 with a cubic structure can contact the inner wall of the adjusting groove 402 to prevent the cutting block 2 from rotating when the adjusting screw 106 rotates, thereby improving the stability of the movement of the cutting block 2. The cutting plate 201 is arranged at the bottom of the cutting block 2, and the cutting knife 202 is arranged on the cutting plate 201. At the same time, in order to prevent the cutting block 2 from deviating during the movement, a guide rod 203 is fixedly connected in the adjusting block 105. The guide rod 203 passes through the adjusting block 105 and is slidably connected to the adjusting block 105. The guide rod 203 can limit the radial movement of the cutting block 2 to keep it stable during the movement. When the staff rotates the adjusting screw 106 to drive the cutting block 2 to move, the moving block 303 will be slidably connected to the guide rod 203.

[0029] In this embodiment, since long-term cutting of stamping parts will cause wear of the cutting knife 202, when the cutting knife 202 contacts the stamping parts, it will be affected by friction and pressure. These forces will gradually wear the cutting edge of the cutting knife 202 and reduce the service life of the cutting knife 202. In order to replace the severely worn blade in time and do a good job of blade maintenance, a cutting groove 2011 is set on the side of the cutting plate 201 away from the stamping block 104, and fixing grooves 2021 are set on both sides of the cutting knife 202. A fixing mechanism for fixing the cutting groove 2011 is set in the cutting groove 2011, and the cutting knife 202 is set in the cutting groove 2011. The cutting groove 2011 is set on the side of the cutting plate 201 away from the stamping block 104 to facilitate the staff to disassemble the cutting knife 202 and perform maintenance.

[0030] Specifically, the fixing mechanism includes a connecting frame 3, a control rod 301, and a plurality of telescopic components. A accommodating space 302 is provided inside the cutting plate 201. The connecting frame 3 is arranged inside the accommodating space 302. Two telescopic components are provided, and the plurality of telescopic components are respectively arranged at the connection of the connecting frame 3. The telescopic components include a moving block 303, a fixing rod 304, and an elastic member 305. The elastic member 305 is a cylindrical compression spring. One end of the elastic member 305 is arranged at the bottom of the accommodating space 302, and the other end of the elastic member 305 abuts against the moving block 303. The moving block 303 is arranged to be tilted downward from the side away from the cutting groove 2011. There is a sliding groove 306 running through it, one end of the fixed rod 304 is slidably connected to the sliding groove 306, and the end of the fixed rod 304 close to the elastic member 305 is provided with a sliding column 405, the sliding column 405 is slidably connected to the sliding groove 306, and the sliding column 405 has a cylindrical structure. The sliding column 405 with a cylindrical structure can reduce the friction between the sliding groove 306, so that the staff can disassemble the cutting knife 202. The other end of the fixed rod 304 runs through the side of the accommodating space 302 and extends into the cutting groove 2011. The control rod 301 is arranged on the side of the connecting frame 3 away from the stamping block 104 and extends out of the accommodating space 302.

[0031] In this embodiment, a slide groove 307 is provided on the side of the cutting plate 201 away from the punching block 104, and the control rod 301 is slidingly connected to the inner wall of the slide groove 307. The sliding connection between the inner wall of the slide groove 307 and the control rod 301 limits the freedom of the control rod 301, thereby limiting the freedom of the connecting frame 3, so that the connecting frame 3 and the control rod 301 can only move up and down. The side of the control rod 301 away from the connecting frame 3 is an arc-shaped structure. The control rod 301 of the arc-shaped mechanism can avoid damage caused by sharp corners to the staff, making it easier for the staff to press.

[0032] In order to facilitate the staff to quickly install the cutting knife 202, a positioning block 403 is set at the top of the cutting groove 2011, and a positioning groove 404 is set at the top of the cutting knife 202. During installation, it is only necessary to align the positioning groove 404 with the positioning block 403 for installation, so that the cutting knife 202 can be quickly positioned.

[0033] When the staff needs to disassemble the cutting knife 202, they only need to move the control rod 301 downward, and the control rod 301 will drive the connecting frame 3 to move downward as a whole, thereby driving the moving block 303 to move in the direction of the compression elastic member 305. When the moving block 303 moves downward, the sliding groove 306 on the moving block 303 will move downward. When the sliding groove 306 moves downward, it will drive the sliding column 405 to retract, thereby retracting the fixing rod 304 into the accommodating space 302, so that the staff can disassemble the cutting knife 202 for maintenance.

[0034] When the staff installs the cutting knife 202, firstly, one hand moves the control rod 301 downward to retract the fixing rod 304, then aligns the positioning groove 404 on the cutting knife 202 with the positioning block 403 and inserts it, and then releases the control rod 301. Under the action of the elastic member 305, the fixing rod 304 will penetrate into the fixing grooves 2021 on both sides of the cutting knife 202 and fix it.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
