[0037] Working principle:

[0038] First, the movable template 2 is driven to move upward and push the steel plate 38 horizontally from front to back to the top of the first support plate 8 in the blanking assembly, and then feeds backward along the top of the first support plate 8 at a certain speed. At the same time, the movable template 2 will also drive the first seat plate 4, the first guide plate 5 and the first pressing plate 6 in the blanking assembly to move up and down repeatedly at a certain frequency. When the bottom of the first pressing plate 6 is attached to the top of the first support plate 8, the first pressing plate 6 will press the steel plate 38 to prevent it from shifting, and the first guide plate 5 and the first pressing plate 6 will both move back upward to place the first seat The plate 4 continues to move downward for a certain distance, so that the bottom of the middle dividing knife plate 9, the bottom of the two side dividing knife plates 10 and the lower ends of the two punching pins 11 pass through the steel plate 38 in sequence and extend into the first knife plate guide block 12, the second knife plate guide block 13 and the first knife plate guide block 12 respectively, thereby punching out materials of corresponding shapes in the steel plate 38 and forming a circular blank 381; when the movable template 2 moves up to make the first pressure plate 6 leave the first support plate 8, the first guide plate 5 and the first pressure plate 6 will both move down and elastically reset. The above structure and principle are all prior art.

[0039] The steel plate 38 is continuously fed backwards, and when the circular blank 381 moves to above the second support plate 19 in the forming assembly, the movable template 2 just moves downward, thereby driving the second seat plate 15, the second pressure plate 17 and the second guide plate 16 in the forming assembly to move downward, until the bottom of the second pressure plate 17 is in contact with the top of the second support plate 19 to prevent the steel plate 38 from shifting; thereafter, the second guide plate 16 and the second pressure plate 17 will both move upward and backward to allow the second seat plate 15 to continue to move downward for a certain distance, thereby allowing the end of the forming column 3 to pass through the steel plate 38 and extend into the forming cavity 201 on the forming block 20, thereby pressing a circular cavity on the circular blank 381; when the movable template 2 moves upward to allow the second pressure plate 17 to leave the second support plate 19, the second guide plate 16 and the second pressure plate 17 will both move downward and elastically reset, and so on.

[0040] When the circular cavity moves to above the fourth support plate 36 in the shaping assembly, the movable template 2 moves downward again, thereby driving the fourth seat plate 31, the fourth pressure plate 32 and the fourth guide plate 33 in the shaping assembly to move downward until the bottom of the fourth pressure plate 32 is in contact with the top of the fourth support plate 36 to prevent the steel plate 38 from shifting; thereafter, the fourth guide plate 33 and the fourth pressure plate 32 will both move upward and backward to allow the fourth seat plate 31 to continue to move downward for a certain distance, thereby allowing the end of each shaping column 34 to be inserted into the circular cavity, and each circular cavity will be shaped each time it passes a shaping column 34; when the movable template 2 moves upward to allow the fourth pressure plate 32 to leave the fourth support plate 36, the fourth guide plate 33 and the fourth pressure plate 32 will both move downward and elastically reset.

[0041] When the shaped circular cavity moves to above the third support plate 24 in the separation assembly, the movable template 2 just moves downward again, thereby driving the third seat plate 21, the third pressure plate 22 and the third guide plate 14 in the separation assembly to move downward until the bottom of the third pressure plate 22 is in contact with the top of the third support plate 24 to prevent the steel plate 38 from shifting; thereafter, the third pressure plate 22 and the third guide plate 14 will both move upward and backward to allow the third seat plate 21 to continue to move downward for a certain distance, thereby allowing the end of the punching column 25 to pass through the bottom of the circular cavity and be inserted into the countersunk hole 242, thereby punching out a portion of material at the bottom of the circular cavity to form a circular structural hole; when the movable template 2 moves upward to allow the third pressure plate 22 to leave the third support plate 24, the third pressure plate 22 and the third guide plate 14 will both move downward and elastically reset.

[0042] Afterwards, when the circular cavity moves to the bottom of the chamfered column 26 in the separation assembly, the chamfered column 26 will follow the third pressure plate 22 to move downward, thereby inserting the step column 261 into the chamfered countersunk hole 243, and the end of the chamfered column 26 and the root of the step column 261 will cooperate with each other to form a chamfered edge at the edge of the opening of the circular cavity.

[0043] When the circular cavity moves to the bottom of the separation column 29 in the separation assembly, the lower end of the separation column 29 will pass through the edge of the opening of the circular cavity and extend into the separation hole 301, thereby separating the circular cavity from the steel plate 38 to form an engine cover.

[0044] The utility model integrates all the processing steps required for the engine cover, and only needs one set of molds to complete all the stamping steps, so there is no need to separately make matching stamping molds for each step, and the steps can be seamlessly connected to each other to achieve connected processing, thereby simplifying the production process to improve processing efficiency; and also reducing the production cost of the mold to reduce the processing cost.

[0045] 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.
