[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 , the utility model provides an embodiment: a stamping die with a feed correction function, comprising a sheet material routing frame 1 and slide plates 7 slidably installed on both sides of the top of the sheet material routing frame 1, an L-shaped slat 8 is installed on the outer wall of the side where the two slide plates 7 are close to each other, and a correction and centering mechanism 9 for driving the slide plate 7 to move is installed on both sides of the outer wall of the sheet material routing frame 1, and a self-falling pressing structure 6 for pressing the sheet material downward is arranged on both sides of the top of the sheet material routing frame 1, a back frame 4 is installed on one side of the back of the sheet material routing frame 1, and a sheet material rolling unit 5 is installed on the outer wall of one side of the back frame 4, and a lower feeding roller 10 is rotatably installed inside the sheet material routing frame 1 below the sheet material rolling unit 5, a stamping die body 2 is installed on the outer wall of one side of the sheet material routing frame 1, and a PLC control panel 3 electrically connected to the stamping die body 2, the sheet material rolling unit 5, and the input end of the correction and centering mechanism 9 is installed on the outer wall of one side of the sheet material routing frame 1;

[0019] The corrective centering mechanism 9 includes an E-shaped seat fixed on the outer wall of one side of the sheet material routing frame 1, and an electric push rod installed on the outer wall of one side of the E-shaped seat. The top end of the piston rod of the electric push rod is fixedly connected to the outer wall of one side of the slide plate 7. The slide plate 7 and the L-shaped slats 8 are made of stainless steel. According to the width of the plate material, the staff turns on the corrective centering mechanism 9 through the PLC control panel 3 to adjust the spacing between the two slide plates 7 and the L-shaped slats 8 until the L-shaped slats 8 are in contact with the side of the plate material, which keeps the sheet material always in the correct position for stamping, effectively preventing the occurrence of position offset and material stripping;

[0020] The stamping die body 2 includes a return frame 201 installed on the outer wall of one side of the sheet material routing frame 1, and a guide column 202 fixed at the inner corner position of the return frame 201. A lower stamping die 203 is fixed at the bottom end of the return frame 201. A hydraulic cylinder 204 is installed at the top of the stamping die body 2. An upper stamping die 205 is installed at the top of the piston rod of the hydraulic cylinder 204. The upper stamping die 205 and four guide columns 202 are slidably matched. When the sheet material is delivered between the lower stamping die 203 and the upper stamping die 205, the upper stamping die 205 is driven downward by the hydraulic cylinder 204. At this time, the lower stamping die 203 and the upper stamping die 205 are molded and the stamping action is completed, thereby completing the stamping work on the sheet material;

[0021] The self-falling material pressing structure 6 includes a U-shaped platform 601 fixed to one side of the top of the sheet material routing frame 1, and a swing arm 602 hingedly installed at the top of the U-shaped platform 601. A pressing wheel 603 is rotatably installed at one end of the swing arm 602, and the sheet material is pressed by the pressing wheel 603. In this process, since the pressing wheel 603 is heavy, one end of the swing arm 602 always swings down, thereby pressing the sheet material. Through the action of gravity, the plate material can be pressed and kept in a suitable position, effectively preventing the sheet material from jumping during the stamping process;

[0022] The outer walls on both sides of the sheet material routing frame 1 are provided with lifting and pushing mechanisms 11, which include an I-shaped seat 1101 installed on the outer wall of one side of the sheet material routing frame 1, and a cylinder 1102 installed at the bottom end of the I-shaped seat 1101, a slide 1103 is slidably installed inside the I-shaped seat 1101, the bottom end of the slide 1103 is fixedly connected to the top end of the piston rod of the cylinder 1102, a bearing seat 1104 is fixed to the top end of the slide 1103, and the lower feed roller 10 is rotatably installed between the two bearing seats 1104. When conveying the sheet material, the lower feed roller 10 is pushed up by the lifting and pushing mechanism 11, so that the lower feed roller 10 and the sheet material rolling unit 5 apply pressure to the sheet material, that is, the cylinder 1102 pushes the slide 1103, the bearing seat 1104 and the lower feed roller 10 upward until the lower feed roller 10 and the sheet material rolling unit 5 apply a certain pressure to the sheet material;

[0023] The sheet material rolling unit 5 includes a reduction motor 501 installed on the outer wall of one side of the back frame 4, and an upper feed roller 502 installed at the output end of the reduction motor 501 through a coupling. When the staff turns on the reduction motor 501 through the PLC control panel 3, the reduction motor 501 drives the upper feed roller 502 to rotate, and the upper feed roller 502 and the lower feed roller 10 are used to transfer the sheet material toward the stamping die body 2, which can realize continuous feeding and continuously feed the sheet material into the stamping area, thereby improving the continuity and efficiency of the stamping process.

[0024] When the embodiment of the present application is in use, the staff first passes the plate and strip material to be punched between the two L-shaped slats 8, and makes the plate and strip material pass through the bottom of the self-falling pressing structure 6 and between the plate material rolling unit 5 and the lower feeding roller 10, and finally introduces it into the stamping die body 2 for stamping. During this process, the staff turns on the correcting centering mechanism 9 through the PLC control panel 3, and the correcting centering mechanism 9 pushes the two L-shaped slats 8 closer to each other, so that the L-shaped slats 8 are used to limit the plate and strip material, and the self-falling pressing structure 6 actively presses the plate and strip material to reduce the vertical movement of the plate and strip material. The sheet metal rolling unit 5 is actuated after each punching action of the punching die body 2. The sheet metal rolling unit 5 and the lower feeding roller 10 jointly convey the sheet metal material forward once. The position of the material is actively corrected through the self-falling pressing structure 6 and the correction centering mechanism 9, so that the sheet metal material can always move on the same horizontal line during the punching process, effectively preventing the position deviation and material stripping problems of the sheet metal. The stable feeding process helps to improve production efficiency, reduce the downtime and adjustment time caused by unstable feeding, and also reduce the generation of waste due to position deviation.
