[0024] The four sets of punching tools can punch the lawn mower blades in four times during the punching process. This setting can avoid the situation where the blades are simultaneously subjected to excessive pressure from the punching tools, which causes the raw materials to tear and affects the quality of the blades. For details, please refer to Figure 4 , the punching process of the blade is completed from left to right;

[0025] See also Figure 1-4The auxiliary component 4 includes two mounting blocks 401 fixedly connected to the top of the support frame 102 and symmetrically distributed. The opposite sides of the two mounting blocks 401 are fixedly connected with support bars 402. The top of the mounting block 401 is fixedly connected with a fixing plate 403. The top of the fixing plate 403 is fixedly connected with a connecting plate 404. A conveying cavity is formed between the connecting plate 404 and the adjacent supporting bars 402. The interior of the fixing plate 403 is provided with a mounting cavity 405. The interior of the mounting cavity 405 is slidably connected with a pressing plate 407. One end of the pressing plate 407 passes through the mounting cavity 405 and extends to the interior of the conveying cavity. A second spring 410 is fixedly connected between the bottom of the pressing plate 407 and the inner wall of the mounting cavity 405, a trigger rod 406 is arranged on the top of the pressing plate 407, the upper end of the trigger rod 406 passes through the fixing plate 403 and the connecting plate 404 in sequence and extends to the outside of the connecting plate 404, a connecting rod 409 is slidably connected to the inner wall of the trigger rod 406, the lower end of the connecting rod 409 passes through the trigger rod 406 and is fixedly connected to the top of the pressing plate 407, a first spring 408 is fixedly connected to the top of the connecting rod 409, and the upper end of the first spring 408 is fixedly connected to the inner top wall of the trigger rod 406;

[0026] The conveying cavity is used for conveying stamping materials, that is, for conveying strip metal. The strip metal can be continuously conveyed by the conveying device and moved along the inner wall of the conveying cavity. The conveying is stopped when the stamping die body 2 moves downward. The distance of each conveying is the distance between two stamping tools, so that the tool stamping can be completed in four times.

[0027] In the process of the hydraulic push rod driving the stamping seat to move downward, the stamping seat first contacts the top of the trigger rod 406. During this process, the trigger rod 406 can be pushed to insert into the installation cavity 405, and the pressure plate 407 is simultaneously driven to move downward and compress the second spring 410 until the pressure plate 407 contacts the top of the stamped metal blank, thereby completing the limiting of the stamped metal blank and avoiding the position displacement of the metal blank affecting the stamping effect during the stamping process. When the pressure plate 407 contacts the stamped metal raw material, it can be blocked by the metal raw material and stop moving downward. At this time, the stamping seat continues to move downward and drives the stamping tool to stamp the metal blank. During this process, the connecting rod 409 can be inserted into the inside of the trigger rod 406 and compress the first spring 408, so that it will not cause excessive extrusion to affect the stamping effect of the metal blank.

[0028] See also Figure 1-4 The collecting assembly 3 includes a through slot 301 opened on the top of the supporting platform 101, a collecting box 302 is detachably provided inside the supporting platform 101, and the collecting box 302 is communicated with the through slot 301. The collecting assembly 3 also includes a guide block 303 fixedly connected to the inside of the discharge cavity, and a surface of the guide block 303 is provided with an inclined surface, and the guide block 303 uses the inclined surface to guide the stamping waste to the through slot 301;

[0029] The metal waste generated by stamping can fall onto the guide block 303, and under the action of the inclined surface of the guide block 303, the metal waste generated by stamping is introduced into the through groove 301, so that it can fall into the inside of the collection box 302 for unified cleaning by the staff, avoiding the situation where the metal waste generated by traditional equipment falls on the table and the cumbersome cleaning operation is required later.

[0030] Working principle: The strip metal can be moved along the inner wall of the conveying cavity through continuous conveying by the conveying equipment. The conveying stops when the stamping die body 2 moves down. The distance of each conveying is the spacing between two stamping tools, so that the tool stamping can be completed in four times. During the stamping process, the metal blank can be fixed and limited under the action of the auxiliary component 4 to facilitate the stamping of the stamping tool, so as to avoid the position deviation of the metal blank during the stamping process affecting the stamping effect. When the pressure plate 407 contacts the stamping metal raw material, it can be blocked by the metal raw material and stop moving down. At this time, the stamping seat continues to move down and drives the stamping tool to stamp the metal blank. During this process, the connecting rod 409 can be inserted into the inside of the trigger rod 406 and compress the first spring 408, so that it will not cause excessive extrusion to affect the stamping effect of the metal blank. The setting of the collection component 3 can collect the waste generated by stamping in time to facilitate unified cleaning by the staff.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, and that the scope of the present invention is defined by the appended claims and their equivalents.
