[0024] Such as Figures 1 to 6As shown in the figure, a stamping die for street lamp production includes a fixing plate 1. The fixing plate 1 is an "L"-shaped block, and there are two fixing plates 1 which are mirror-symmetrically distributed. The upper sides of the two fixing plates 1 are fixedly connected with a first connecting plate 2. The upper side of the first connecting plate 2 is symmetrically and fixedly connected with two support plates 3. The support plates 3 are rectangular blocks. The upper sides of the two support plates 3 are fixedly connected with a second connecting plate 4. A stamping structure is arranged on the side of the second connecting plate 4. The stamping structure includes a connecting frame 511 fixedly connected to the side of the second connecting plate 4. A fixed punching press 512 is arranged on the side of the connecting frame 511 corresponding to the position of the supporting plate 616. The output end of the punching press 512 is fixedly connected with an extrusion upper die 513 corresponding to the position of the supporting plate 616. Start the punching press 512, and the punching press 512 drives the extrusion upper die 513 to press down on the iron sheet. Above the second connecting plate 4, there is a movable supporting plate 616. Both sides of the supporting plate 616 are provided with first installation cavities 621. The upper side center position of the supporting plate 616 is provided with a forming cavity. An active auxiliary positioning structure is arranged inside the first installation cavity 621. An active supporting structure is arranged on the upper side of the first connecting plate 2. Place the iron sheet to be extruded and formed above the supporting plate 616, restrain the iron sheet through the auxiliary positioning structure, start the stamping and forming structure, and the stamping and forming structure extrudes the patch to the forming cavity at the upper side center position of the supporting plate 616, and presses the upper part of the iron sheet. After the extrusion is completed, then move the supporting structure to make the supporting plate 616 move upward. The supporting plate 616 presses the lower part of the patch to make the iron sheet formed. After forming, then move the iron sheet away from the upper side of the supporting plate 616 through the auxiliary positioning structure to quickly position the iron sheet, and also achieve automatic blanking, improving work efficiency. The upper side of the first connecting plate 2 is fixedly connected with an installation barrel 611. The outer side of the installation barrel 611 is slidably connected with a sliding barrel 612. The upper side of the installation barrel 611 is fixedly connected with a spring 613. Two limiting cavities 651 are symmetrically opened inside the sliding barrel 612. The outer side of the installation barrel 611 is fixedly connected with a second limiting block 652 corresponding to the position of the limiting cavity 651. The second limiting block 652 is slidably connected inside the limiting cavity 651. The upper side of the sliding barrel 612 is fixedly connected with a third connecting plate 614. The upper side of the third connecting plate 614 is equidistantly fixedly connected with connecting columns 615. The connecting columns 615 extend upward and are fixedly connected to the bottom side of the supporting plate 616. The side of the fixing plate 1 is fixedly connected with a hydraulic telescopic cylinder 661. The output end of the hydraulic telescopic cylinder 661 is fixedly connected with an extrusion column 662. The extrusion column 662 extends above the installation barrel 611. The downward movement of the sliding barrel 612 causes the displacement of the limiting cavity 651 and the second limiting block 652. The second limiting block 652 contacts the side of the limiting cavity 651 to form a limit, so as to limit the movement of the sliding barrel 612, thereby supporting and limiting the supporting plate 616. Start the hydraulic telescopic cylinder 661, and the hydraulic telescopic cylinder 661 makes the extrusion column 662 press on the sliding barrel 612.Further, the sliding bucket 612 drives the third connecting plate 614, the connecting column 615 and the supporting plate 616 upward.

[0025] The auxiliary positioning structure includes a swing block 624 movably installed on the side of the first installation cavity 621. A second installation cavity 622 is formed on the side of the supporting plate 616. A fixed rotary motor 623 is arranged inside the second installation cavity 622. The output end of the rotary motor 623 is fixedly connected to the side of the swing block 624. After the iron sheet is extruded and formed, the rotary motor 623 is started. The rotary motor 623 rotates, and the formed iron sheet is moved out from above the supporting plate 616. An adaptation cavity 631 is formed on the bottom side of the swing block 624. An electromagnet 632 is fixedly connected to the side of the first installation cavity 621 corresponding to the position of the adaptation cavity 631. A start button 633 is fixedly connected to the side of the supporting plate 616. When the iron sheet is placed on the supporting plate 616, the start button 633 is pressed. The start button 633 energizes the electromagnet 632, and the electromagnet 632 adsorbs and positions the iron sheet on the supporting plate 616. When the swing block 624 swings, the iron sheet breaks away from the restraint of the electromagnet 632. A groove 641 is formed on the upper side of the supporting plate 616. A first limiting block 642 is fixedly connected to the side of the first installation cavity 621 corresponding to the position of the groove 641. The first limiting block 642 is an arc-shaped block. Two sliding cavities 643 are symmetrically formed on the upper side of the supporting plate 616. The sliding cavities 643 are "L"-shaped cavities. Sliding blocks 644 are slidably connected inside the two sliding cavities 643. Pressing blocks 645 are fixedly connected to the upper sides of the sliding blocks 644 corresponding to the positions of the sliding cavities 643. Handles 646 are fixedly connected to the sides of the two sliding blocks 644. When the iron sheet is placed above the supporting plate 616, the side of the iron sheet is constrained by the first limiting block 642, and then the two sliding blocks 644 are moved. The two sliding blocks 644 drive the two pressing blocks 645 to extrude the other side of the iron sheet to calibrate the iron sheet.

[0026] In summary: Place the iron sheet to be extrusion-molded above the support plate 616, constrain the iron sheet through the auxiliary positioning structure, start the stamping and forming structure. The stamping and forming structure extrudes the patch to the forming cavity at the center position on the upper side of the support plate 616, and extrudes the upper part of the iron sheet. After the extrusion is completed, the support plate 616 is moved upward through the moving support structure, and the support plate 616 extrudes the lower part of the patch to form the iron sheet. After forming, the iron sheet is moved away from above the support plate 616 through the auxiliary positioning structure to quickly position the iron sheet and also achieve automatic blanking. Start the press 512, and the press 512 drives the extrusion upper die 513 to press downward on the iron sheet. When placing the iron sheet on the support plate 616, press the start button 633. The start button 633 energizes the electromagnet 632, and the electromagnet 632 adsorbs the iron sheet on the support plate 616 for positioning. When the swing block 624 swings, the iron sheet breaks away from the restraint of the electromagnet 632. When the iron sheet is placed above the support plate 616, the side of the iron sheet is constrained by the first limit block 642, and then two sliding blocks 644 are moved. The two sliding blocks 644 drive two extrusion blocks 645 to extrude the other side of the iron sheet to calibrate the iron sheet. The sliding barrel 612 moves downward, causing a displacement between the limit cavity 651 and the second limit block 652. The second limit block 652 contacts the side of the limit cavity 651 to form a limit, thereby limiting the movement of the sliding barrel 612 and thus supporting and limiting the support plate 616. Start the hydraulic telescopic cylinder 661, and the hydraulic telescopic cylinder 661 causes the extrusion column 662 to extrude the sliding barrel 612, and further drives the third connecting plate 614, the connecting column 615 and the support plate 616 upward through the sliding barrel 612.
