DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Such as Figures 1-3As shown in the figure, a double-punch knife drawing machine includes an operating table 1. One end of the operating table 1 is fixedly connected with a mounting frame 2. One end of the mounting frame 2 is fixedly connected with a main slide rail 3 near the upper side of the operating table 1. The outer side of the main slide rail 3 is slidably connected with a main slide carriage 4. The front end of the main slide carriage 4 is provided with a double-punch knife mechanism 7. The double-punch knife mechanism 7 includes a fixing plate 71 fixedly connected to the front end of the main slide carriage 4. The front end of the fixing plate 71 is fixedly connected with a secondary slide rail 72. One side of the front end of the fixing plate 71 near the secondary slide rail 72 is fixedly connected with a control frame 73. The outer side of the secondary slide rail 72 is slidably connected with a secondary slide carriage 74. The front end of the secondary slide carriage 74 is fixedly connected with a connecting member 75. A lead screw 76 is movably connected inside the control frame 73. A moving rod 77 is slidably connected inside the connecting member 75. A limiting rod 78 is slidably connected to one side of the inside of the connecting member 75 near the moving rod 77. A spring 79 is movably connected to the outer side of the moving rod 77. The lower end of the moving rod 77 is fixedly connected with a docking block 710. The lower end of the limiting rod 78 is fixedly connected with a drawing knife 711. The upper end of the lead screw 76 is fixedly connected with a turning handle 712.

[0020] In this embodiment, the upper end of the moving rod 77 is fixedly connected with a linkage block 713. One end of the linkage block 713 is fixedly connected with a fixing frame 714. The inside of the fixing frame 714 is fixedly connected with the outer side of the limiting rod 78. The lead screw 76 passes through the other side of the inside of the connecting member 75 near the moving rod 77. The lead screw 76 is threadedly connected with the connecting member 75. The upper end of the spring 79 is fixedly connected with the lower end of the connecting member 75. The lower end of the spring 79 is fixedly connected with the outer side of the upper end of the docking block 710 near the moving rod 77. One end of the drawing knife 711 is fixedly connected with one end of the docking block 710. The number of the moving rod 77, the limiting rod 78, the spring 79, the docking block 710, and the drawing knife 711 is two groups.

[0021] Specifically, reverse-rotate the turning handle 712 to move the connecting member 75 downward, so that the drawing knife 711 contacts the raw material. And then rotate the turning handle 712 again to move the connecting member 75 downward again, and make the connecting member 75 move downward along the moving rod 77 and the limiting rod 78, and make the connecting member 75 compress the spring 79, so that the spring 79 always has a downward acting force on the drawing knife 711 through the docking block 710, and the drawing knife 711 always contacts the raw material. Then pull the main slide carriage 4 to move along the main slide rail 3, so that the main slide carriage 4 drives the double-punch knife mechanism 7 to move, and the two groups of drawing knives 711 can be moved. By moving the connecting member 75 downward, the two groups of drawing knives 711 contact the raw material, and under the elastic action of the spring 79, the spring 79 always has a downward acting force on the drawing knives 711. Then move the main slide carriage 4, which can achieve the purpose of facilitating the movement of the two groups of drawing knives 711, and make the two groups of drawing knives 711 draw lines on the raw material, so that double lines can be drawn on the raw material, and the drawing efficiency of workers can be improved.

[0022] In this embodiment, a support frame 5 is fixedly connected to the rear end of the operating table 1, a push rod 6 is fixedly connected to the upper end of the main slide carriage 4, and support legs 8 are fixedly connected to the lower end of the operating table 1.

[0023] Specifically, through the function of the support legs 8, the purpose of facilitating the support of the operating table 1 can be achieved, and the stability of the operating table 1 when the worker draws lines on the raw materials can be increased.

[0024] Working principle:

[0025] During use, first rotate the turning handle 712, which causes the lead screw 76 to rotate, and the connecting member 75 drives the auxiliary slide carriage 74 to slide along the auxiliary slide rail 72, increasing the distance between the line drawing knife 711 and the operating table 1. Then, lay the raw materials flat on the operating table 1. Next, rotate the turning handle 712 in the reverse direction, causing the connecting member 75 to move downward, so that the line drawing knife 711 contacts the raw materials. And then rotate the turning handle 712 again, causing the connecting member 75 to move downward again, and the connecting member 75 moves downward along the moving rod 77 and the limiting rod 78, and the connecting member 75 compresses the spring 79. Thus, the spring 79 always exerts a downward force on the line drawing knife 711 through the docking block 710, and the line drawing knife 711 always contacts the raw materials. Then, pull the push rod 6, which drives the main slide carriage 4 to move along the main slide rail 3, so that the main slide carriage 4 drives the double punching knife mechanism 7 to move, enabling the two line drawing knives 711 to move, and the two line drawing knives 711 to draw lines on the raw materials, thus drawing double lines on the raw materials. By moving the connecting member 75 downward, the two line drawing knives 711 contact the raw materials, and under the elastic action of the spring 79, the spring 79 always exerts a downward force on the line drawing knife 711. Then, moving the main slide carriage 4 can achieve the purpose of facilitating the movement of the two line drawing knives 711, and enabling the two line drawing knives 711 to draw lines on the raw materials, thus drawing double lines on the raw materials, which can improve the line drawing efficiency of the worker.
