For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0051] As Figures 1 to 6 shown, the pressing tool head 100 of the present utility model is used to press the indentation knife 220 as Figure 7 shown into the knife slot of the knife template 210, so as to obtain the finished knife die 200. The finished knife die 200 includes a knife template 210, an indentation knife 220 and a cutting knife 230 embedded in the knife template 210.

[0052] As Figures 1 to 6 shown, the pressing tool head 100 includes a moving mechanism 10 and a pressing mechanism 20. The moving mechanism 10 is used to drive the pressing mechanism 20 to move to meet the requirements of the pressing process. The pressing mechanism 20 includes a connecting seat 21 assembled and connected with the moving mechanism 10, a first knife clamping module 22 arranged on one side of the connecting seat 21, a first pressing head 23 arranged on the upper end of the first knife clamping module 22, a downward pressing power element 24 (in this embodiment, the downward pressing power element 24 uses a cylinder) arranged on the upper end of the first pressing head 23, and a second knife clamping module 25 arranged on the front end face of the connecting seat 21. As Figures 4 to 6 shown, a downward pressing surface 26 is provided on the lower end surface of the connecting seat 21, and the downward pressing surface 26 is a horizontal plane; a second pressing head 27 protruding downward is provided on the downward pressing surface 26; the downward pressing surface 26 includes a first long side 261 and a second long side 262 arranged in parallel, and the second pressing head 27 is arranged on one side of the downward pressing surface 26 close to the second long side 262. A working gap 263 is provided between the second pressing head 27 and the first long side 261; a convex block is provided downward at the central part of the second pressing head 27, and the lower end of the convex block is lower than the downward pressing surface 26.

[0053] Among them, the first knife clamping module 22 and the second knife clamping module 25 are used to clamp the indentation knife 220, preventing the indentation knife 220 from tilting due to vibration during the knife pressing process, which affects the quality of knife pressing. During the actual processing, according to the length of the indentation knife 220, the first knife clamping module 22 can be used alone or the first knife clamping module 22 and the second knife clamping module 25 can be used simultaneously to adapt to various indentation knives 220 of different lengths. The first pressing head 23, the lower pressing surface 26 and the second pressing head 27 are used to press down the indentation knife 220 and press the indentation knife 220 into the knife slot of the knife template 210.

[0054] At the same time, the first knife clamping module 22 and the second knife clamping module 25 are arranged in a straight line to prevent the indentation knife 220 from being bent when the first knife clamping module 22 and the second knife clamping module 25 clamp the indentation knife 220 at the same time. At the same time, the lower end surfaces of the connecting seat 21, the first knife clamping module 22 and the second knife clamping module 25 are on the same horizontal plane to avoid interference during the downward pressing process.

[0055] Next, it is necessary to elaborate on the working principle of the knife pressing tool head 100 of the present invention: for the convenience of description, both ends of the indentation knife 220 have a starting end 220a and a terminal end 220b, and both ends of the lower pressing surface 26 have a head 26a and a tail 26b; in addition, the indentation knife 220 has been preset and aligned with the knife slot of the knife template 210.

[0056] Please refer to Figures 8 to 13 , when the length of the indentation knife 220 is greater than the length of the first knife clamping module 22, the following steps are adopted:

[0057] The first step is as Figure 8 shown, the first pressing head 23 aligns with the starting end 220a of the indentation knife 220 and presses down, and the starting end 220a of the indentation knife 220 is pressed into the knife slot of the knife template 210 to complete the preliminary positioning of the indentation knife 220;

[0058] The second step is as Figure 9 shown, the first pressing head 23 moves along the length direction of the indentation knife 220 towards the terminal end 220b of the indentation knife 220. Every time it moves a certain distance, the first pressing head 23 presses down on the indentation knife 220, and the complete positioning of the indentation knife 220 is completed through multiple step-by-step pressings of the first pressing head 23;

[0059] The third step is as Figure 10 and Figure 11As shown, the head 26a of the lower pressing surface 26 is flush with the starting end 220a of the indentation knife 220. The lower pressing surface 26 moves downward to press the indentation knife 220. After the above downward pressing is completed, the lower pressing surface 26 moves along the length direction of the indentation knife 220 towards the end 220b of the indentation knife 220. Every time it moves a certain distance, the lower pressing surface 26 presses the indentation knife 220. Specifically, in the third step, the contact position between the lower pressing surface 26 and the indentation knife 220 is between the working gaps 263 of the lower pressing surface 26. Therefore, the indentation knife 220 will not interfere with the second pressing head 27 during this process.

[0060] As Figure 12 shown, after the lower pressing surface 26 moves a certain distance, the tail 26b of the lower pressing surface 26 will extend beyond the end 220b of the indentation knife 220. At this time, when the lower pressing surface 26 presses down, it will interfere with the cutting knives 230 on both sides of the indentation knife 220, and the cutting knives 230 will scratch the lower pressing surface 26. Therefore, the fourth step is required. As Figure 13 shown, align the second pressing head 27 with the indentation knife 220, and drive the second pressing head 27 to press down step by step along the length direction of the indentation knife 220, and press the indentation knife 220 to the installation depth, thereby completing the pressing down of the indentation knife 220.

[0061] Please refer to Figures 14 to 15 shown, when the length of the indentation knife 220 is less than the length of the first knife clamping module 22, the following steps are adopted:

[0062] The first step, as Figure 14 shown, the first pressing head 23 presses down, and the first pressing head 23 presses the blade body of the indentation knife 220 into the knife slot.

[0063] The second step, as Figure 15 shown, the knife pressing mechanism 20 makes a position adjustment, the second pressing head 27 presses down, and presses the indentation knife 220 to the installation depth to complete the knife pressing of the indentation knife 220.

[0064] It can be understood that when the length of the indentation knife 220 is much less than the length of the first knife clamping module 22 and there is no interference from the cutting knives 230 on both sides of the indentation knife 220 during the pressing process, the first pressing head 23 can directly press the indentation knife 220 to the installation depth without using the second pressing head 27.

[0065] Specifically, the first knife clamping module 22 includes a first clamping cylinder 221 fixed to the side surface of the connecting seat 21 and two clamping arms 222 symmetrically distributed at the lower end of the first clamping cylinder 221; the first clamping cylinder 221 drives the clamping arms 222 to approach each other to clamp the indentation knife 220. Specifically, an inclined surface 223 is provided at the end of the clamping arm 222 facing the first pressing head 23, and the inclined surface 223 is used to clear the first pressing head 23 to prevent interference between the downward pressing of the first pressing head 23 and the clamping arm 222. Further, an extension arm 224 extends from the end of the clamping arm 222 facing the first pressing head 23, and the extension arm 224 protrudes from one end of the clamping arm 222 to expand the knife clamping range and better clamp the indentation knife 220.

[0066] Further, a clamping groove 225 is provided on the opposite side of the clamping arm 222, and an abutting surface 225a is provided at the top of the clamping groove 225. The abutting surface 225a is higher than the upper end surface of the extension arm 224. The clamping arms 222 are driven by the first clamping cylinder 221 to close together so that the indentation knife 220 is clamped in the clamping groove 225.

[0067] Next, a further explanation is made. When the indentation knife 220 is clamped in the clamping groove 225, the top of the indentation knife 220 abuts against the abutting surface 225a; thus, it can be understood that the height difference between the abutting surface 225a and the top surface of the extension arm 224 is the downward pressing depth of the first pressing head 23 driving the indentation knife 220.

[0068] Specifically, the second knife clamping module 25 includes a second clamping cylinder 251 fixed to the front end surface of the connecting seat 21 and a clamping block 252 provided at the lower end of the second clamping cylinder 251; the second clamping cylinder 251 drives the clamping block 252 to move towards the front end surface of the connecting seat 21 to clamp the indentation knife 220.

[0069] Specifically, the motion mechanism 10 includes a horizontally moving component (not shown in the figure), a lifting component 11, and a rotating component 12 that are assembled and connected; the horizontally moving component is used to drive the knife pressing mechanism 20 to perform horizontal movement along the x-axis and the y-axis; the lifting component 11 is used to drive the knife pressing mechanism 20 to perform vertical lifting along the z-axis; the rotating component 12 drives the knife pressing mechanism 20 to rotate in the horizontal plane formed by the x-axis and the y-axis.

[0070] Among them, the transverse movement component can be realized by a linear module or a motor screw, etc. The lifting component 11 includes a lifting drive motor 111, a lead screw 112 drivingly connected to the lifting drive motor 111, and a lifting plate 113 connected to the lead screw 112; the lifting drive motor 111 drives the lifting plate 113 to lift, thereby driving the knife pressing mechanism 20 to lift. The lifting component 11 further includes a support frame 114 assembled on the transverse movement component and a guide rail 115 fixed on the support frame 114; the lifting drive motor 111 is fixed on the support frame 114, the lifting plate 113 is slidably connected to the guide rail 115, the guide rail 115 is vertically arranged, and the lifting plate 113 always vertically lifts along the guide rail 115.

[0071] The rotating component 12 is respectively connected to the lifting plate 113 and the knife pressing mechanism 20. The rotating component 12 includes a connecting piece 121 assembled and connected to the front end of the lifting plate 113 and a rotating motor 122 fixed to the upper end of the connecting piece 121; the rotating end of the rotating motor 122 penetrates downward through the connecting piece 121 and is fixedly connected to the connecting seat 21; the rotating component 30 can drive the knife pressing mechanism 20 to rotate in the horizontal plane to adapt to knife marks at different angles.

[0072] As Figures 8 to 13 shown, a knife pressing method according to the first embodiment of the present invention uses the above-mentioned knife pressing tool head 100, and the length of the indentation knife 220 targeted by this knife pressing method is greater than the length of the first knife clamping module 22. Specifically, it includes the following steps:

[0074] S2. Preliminary positioning: As Figure 8 shown, the downward pressing power element 24 drives the first pressing head 23 to press downward, and the first pressing head 23 presses the starting end 220a of the indentation knife 220 into the knife slot; during this process, the first knife clamping module 22 and the second knife clamping module 25 clamp the indentation knife 220 to prevent shaking.

[0075] S3. Complete positioning: As Figure 9 shown, the knife pressing mechanism 20 moves a certain distance along the length direction of the indentation knife 220, the downward pressing power element 24 drives the first pressing head 23 to press downward, and the first pressing head 23 presses the blade body of the indentation knife 220 into the knife slot; the first pressing head 23 presses the indentation knife 220 step by step along the length direction of the indentation knife 220 until the end 220b of the indentation knife 220 is pressed into the knife slot; during this process, the first knife clamping module 22 and the second knife clamping module 25 always clamp the indentation knife 220 to ensure that the indentation knife 220 is vertically pressed downward.

[0076] S4. First alignment: As Figure 10As shown, the knife pressing mechanism 20 moves so that the downward pressing surface 26 is located above the indentation knife 220, and at the same time, the starting end of the downward pressing surface 26 is aligned with the starting end of the indentation knife 220;

[0077] S5. First knife pressing: As Figure 11 shown, the lifting assembly 10 drives the knife pressing mechanism 20 to move downward, and the downward pressing surface 26 presses down on the indentation knife 220; the knife pressing mechanism 20 moves a certain distance along the length direction of the indentation knife 220, and the downward pressing surface 26 moves downward to press down again; the downward pressing surface 26 presses down on the indentation knife 220 step by step along the length direction of the indentation knife 220 until the end of the downward pressing surface 26 exceeds the end of the indentation knife 220; during this process, the first knife clamping module 22 and the second knife clamping module 25 always clamp the indentation knife 220 to ensure that the indentation knife 220 is pressed down vertically;

[0078] S6. Second alignment: As Figure 13 shown, the knife pressing mechanism 20 moves so that the second pressing head 27 is located above the end 220b of the indentation knife 220;

[0079] S7. Second knife pressing: As Figure 13 shown, the lifting assembly 10 drives the knife pressing mechanism 20 to move downward, and the second pressing head 27 presses down on the end 220b of the indentation knife 220; the knife pressing mechanism 20 moves a certain distance along the length direction of the indentation knife 220, and the second pressing head 27 moves downward to press down again; the second pressing head 27 presses down on the indentation knife 220 step by step along the length direction of the indentation knife 220.

[0080] As Figure 14 and Figure 15 shown, it is a knife pressing method according to the second embodiment of the present invention, using the above-mentioned knife pressing tool head 100, and the length of the indentation knife 220 targeted by this knife pressing method is less than the length of the first knife clamping module 22. It specifically includes the following steps:

[0081] S1. Feeding: The first knife clamping module 22 clamps the indentation knife 220, and the moving mechanism 10 drives the indentation knife 220 to move above the knife slot;

[0082] S2. First knife pressing: As Figure 14 shown, the downward pressing power element 24 drives the first pressing head 23 to press down, and the first pressing head 23 presses the blade body of the indentation knife 220 into the knife slot; during this process, the first knife clamping module 22 remains in a clamped state;

[0083] S3. Second knife pressing: As Figure 15 shown, the moving mechanism 10 drives the knife pressing mechanism 20 to move so that the second pressing head 27 is located at the upper end of the indentation knife 220; the moving mechanism 10 drives the knife pressing mechanism 20 to press down, and the second pressing head 27 presses down on the indentation knife 220; during this process, the first knife clamping module 22 remains in a clamped state.

[0084] Compared with the prior art, for the pressing tool head involved in the present utility model, the mechanical automation completes the downward pressing of the indentation knife 220, which can reduce the pressing error and improve the pressing efficiency; it includes a first knife clamping module 22 and a second knife clamping module 25, which are used to clamp the indentation knife 220 during the pressing process to avoid shaking and affecting the pressing quality. At the same time, two groups of knife clamping dies 200 are selected to adapt to indentation knives 220 of different lengths, and the application range is wide; it also includes a first pressing head 23, a downward pressing surface 26, and a second pressing head 27; the first pressing head 23 presses the indentation knife 220 into the knife slot by means of multiple-step downward pressing to achieve the positioning purpose; the downward pressing surface 26 presses the indentation knife 220 to a deeper depth by means of multiple-step downward pressing; since the downward pressing surface 26 is a plane, when the downward pressing surface 26 presses the end of the indentation knife 220, it is easily damaged by the cutting knife 230 on the knife template 210. Therefore, the end of the indentation knife 220 is pressed by the second pressing head 27 with a smaller contact surface to avoid damage and extend the service life of the pressing tool head 100.

[0085] The above only expresses the preferred technical solution of the present utility model, and its description is relatively specific and detailed, but it should not be construed as a limitation of the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these changes and modifications.
