[0042] Working principle:

[0043] First, the stamping die 1 is driven to move upward and the steel plate 3 is pushed horizontally from the back to the top of the positioning plate 23, and then fed forward along the top of the positioning plate 23 at a certain speed. At the same time, the stamping die 1 will also repeatedly move up and down at a certain frequency. When the pressure plate 15 is against the positioning plate 23, the guide plate 14 and the pressure plate 15 will both retract upward to allow the knife plate 13 to continue to move downward a certain distance; when the stamping die 1 moves upward to allow the pressure plate 15 to leave the positioning plate 23, the guide plate 14 and the pressure plate 15 will both move downward and elastically reset. The above structure and principle are all prior art.

[0044] When the steel plate 3 moves to the top of the first positioning block 24, the stamping die 1 just moves downward, so that the bottom of the pressure plate 15 is pressed against the steel plate 3 to prevent the steel plate 3 from shifting; then, the end of the first sheet cutter 16 on the knife plate 13 extends to the bottom of the pressure plate 15 and extends into the first positioning groove 241, and then with the help of the first sheet cutter 16 and the first dividing block 161 on the first sheet cutter 16, a part of the material is punched out on the left side of the steel plate 3 in turn, after which the stamping die 1 will move up and reset; after repeating the above steps, an extension sheet 311 located at the left end of the water tank bracket 31 is formed between each position on the steel plate 3 that is punched out.

[0045] When the root of the extension piece 311 moves to above the second positioning block 28, the stamping die 1 just moves downward again, and the first bending notch 1101 on the first bending column 110 presses the extension piece 311 above the first positioning notch 281, thereby forming a first bending section 312 at the root of the extension piece 311. After that, the stamping die 1 will move up and reset.

[0046] When the end of the extension piece 311 moves to the top of the positioning hole 231, the stamping die 1 just moves downward again, and the end of the second bending column 17 extends to the bottom of the pressing plate 15 and extends into the positioning hole 231, thereby bending the end of the first bending section 312 downward to form a second bending section 315. After that, the stamping die 1 will move up and reset.

[0047] When the end of the second bending section 315 moves to between the outer pressure block 26 and the inner pressure block 27 in the hook forming assembly, the stamping die 1 just moves downward again, and the end of the driving column 18 extends below the pressing plate 15 and causes the first inclined surface 181 at the end of the driving column 18 to move downward along the second inclined surface 262 on the outer pressure block 26, thereby forcing the arc-shaped bending groove 261 on the outer pressure block 26 to move toward the end of the second bending section 315, and the first bending section 312 cooperates with each other to sink into the second positioning notch 271 on the inner pressure block 27 and push the inner pressure block 27 to move downward, thereby forcing the inner pressure block 27 to move obliquely downward in the direction of the outer pressure block 26, and then under the mutual cooperation of the end of the protrusion 272 on the inner pressure block 27, a bent hook section 316 is formed at the end of the second bending section 315; thereafter, the stamping die 1 will move up and reset.

[0048] When the right end of the water tank bracket 31 moves to the top of the carrier block 210, the stamping die 1 just moves downward again, and the end of the waist-shaped knife column 114 extends to the bottom of the pressure plate 15 and acts on the top of the right end of the water tank bracket 31, and then with the cooperation of the waist-shaped block 2101 on the carrier block 210, a waist-shaped hole 314 is opened at the right end of the water tank bracket 31; at the same time, the first bending section 312 also just moves to the bottom of the columnar cutter 115, and the end of the columnar cutter 115 extends to the bottom of the pressure plate 15 and acts on the top of the first bending section 312, and then a circular hole 317 is opened in the first bending section 312; thereafter, the stamping die 1 will move up and reset.

[0049] Finally, when the steel plate 3 moves to the top of the third positioning block 25, the stamping die 1 just moves downward again, and the end of the second sheet cutter 19 will extend to the bottom of the pressing plate 15 and extend into the second positioning groove 251, and then with the help of the second sheet cutter 19 and the second dividing block 191 on the second sheet cutter 19, a part of the material on the right side of the steel plate 3 is punched out in turn, and then the stamping die 1 will move up and reset; after repeating the above steps, each time a part of the material on the right side of the steel plate 3 is punched out, the final formed water tank bracket 31 will be separated in turn.

[0050] Before the steel plate 3 moves to the first positioning block 24, it will first pass under the nameplate forming block 112 and the rib bag upper forming block 113 in turn. When the end of the nameplate forming block 112 extends to the bottom of the pressing plate 15 and is pressed against the top of the steel plate 3, a nameplate area with a concave and convex distribution will be formed; when the rib bag upper forming block 113 and the rib bag lower forming block 29 press the top and bottom of the steel plate 3 respectively, the convex rib 313 will be pre-formed on the water tank bracket 31 with the help of the mutual cooperation between the rib groove 1131 and the rib 291.

[0051] The utility model can complete all the steps required for the processing of the water tank bracket 31 in a certain smooth sequence with the help of only one set of stamping dies. It does not need to be divided into several steps, nor does it need to make stamping dies matching each step, thereby reducing the mold manufacturing cost to reduce the processing cost, and there is no need to transfer the automobile water tank bracket and repeatedly take it out of the mold and put it into the mold, thereby simplifying the operating steps to achieve the effect of saving time and labor and improving the processing efficiency.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents.
