Description

Technical Field

[0001] This utility model relates to the field of baffle plate stamping technology, specifically a stamping die for baffle plate processing. Background Technology

[0002] In the manufacturing of kitchen appliances such as range hoods, corrugated baffles are components used to change the direction of fluid flow, improve grease separation, and assist in smoke collection. They are usually designed in a corrugated shape to increase the contact area with oil fumes. During the stamping process of corrugated baffles, sometimes the formed baffle sticks to the upper die after the stamping action is completed, making it difficult for the baffle to be demolded smoothly from the upper die, affecting production efficiency. Manual removal can easily damage the surface quality of the baffle and reduce the product qualification rate. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a stamping die for processing baffle plates, comprising: a support base 1; a top fixing frame 2 fixed to the top of the support base 1 by bolts; a hydraulic cylinder 3 installed on the top of the top fixing frame 2 by bolts, an adjusting support plate 4 fixedly installed at the output end of the hydraulic cylinder 3, and a plurality of guide rods 9 symmetrically slidably arranged inside the adjusting support plate 4, one end of the guide rod 9 being fixedly connected to the support base 1, and the other end of the guide rod 9 being fixedly connected to the top fixing frame 2; and a limiting support box 19 symmetrically fixed to the adjusting support plate 2. At the bottom of plate 4, a limiting support plate 20 is slidably installed inside the limiting support box 19; the mounting plate 5 is fixedly installed at the bottom of the limiting support plate 20 by bolts; the upper stamping die 6 is installed at the bottom of the mounting plate 5 by bolts; the second ejector pin 10 is equidistantly slidably installed inside the upper stamping die 6, and the second ejector pin 10 is slidably connected to the mounting plate 5; the lower stamping die 7 is installed at the top of the support base 1 by bolts, and multiple first ejector pins 8 are equidistantly slidably installed inside the lower stamping die 7, and the first ejector pins 8 are slidably connected to the support base 1.

[0026] It should be noted that in this embodiment, the metal plate used for processing the baffle is placed on the lower stamping die 7. The output end of the hydraulic cylinder 3 drives the adjusting support plate 4 to move downward. The adjusting support plate 4 drives the limiting support box 19, the limiting support plate 20, the second damper 25, the top frame 24, the mounting plate 5, and the upper stamping die 6 to move downward. Through the cooperation between the upper stamping die 6 and the lower stamping die 7, the metal plate is stamped to obtain the wave-shaped range hood baffle. When the upper stamping die 6 is stamping, the metal plate is pressed by the lower stamping die 7. The second dampers 25 and the third spring 26 on the top of the mounting plate 5 buffer the stamping process. When the mounting plate 5 moves, it drives the top frame 24, support frame 21, first hydraulic cylinder 22, and second ejector pin 10 to move as a whole. After the stamping work is completed, the output end of the hydraulic cylinder 3 drives the adjusting support plate 4 to move upward, and the output end of the first hydraulic cylinder 22 drives the second pin plate 23 and the second ejector pin 10 to move downward. The second ejector pin 10 assists in ejecting the baffle plate that has stuck on the upper stamping die 6. After ejection, the output end of hydraulic cylinder 22 drives needle plate 23 and ejector pin 10 to return to their original position. When adjusting support plate 4 moves upward until the bottom position of auxiliary top plate 18, the output end of hydraulic cylinder 3 still drives adjusting support plate 4 to move upward. Adjusting support plate 4 pushes auxiliary top plate 18, and auxiliary top plate 18 drives fixed support plate 13 and needle plate 12 to move upward. Fixed support plate 13 presses spring 17, and needle plate 12 presses damper 14 and spring 15. The No. 1 needle plate 12 drives each No. 1 ejector pin 8 at the top to move upward. The No. 1 ejector pin 8 ejects the baffle plate that is stuck on the stamping die 7, making it easier to remove the baffle plate after stamping. After removal, the output end of the hydraulic cylinder 3 drives the adjusting support plate 4 to move downward a certain distance, which facilitates the reset of the No. 1 damper 14, the No. 1 spring 15 and the No. 2 spring 17. This drives the No. 1 needle plate 12, the fixed support plate 13 and the auxiliary top plate 18 to reset downward, which is convenient for the next stamping operation.

[0027] In one embodiment, such as Figures 1 to 4 As shown, it also includes a fixed base box 11, which is installed at the bottom of the support base 1 by bolts. A first needle plate 12 is slidably arranged inside the fixed base box 11. The bottom end of the first pin 8 is fixedly connected to the first needle plate 12. A fixed support plate 13 is symmetrically fixed to the top of the first needle plate 12. The fixed support plate 13 is slidably connected to the support base 1.

[0028] It should be noted that in this embodiment, the No. 1 ejector plate 12 drives each No. 1 ejector pin 8 at the top to move. The No. 1 ejector pin 8 slides in the support base 1 and the lower stamping die 7. The No. 1 ejector pin 8 assists in ejecting the baffle plate formed by stamping on the lower stamping die 7, so as to avoid the situation of difficulty in removing the material after sticking.

[0029] In one embodiment, such as Figures 1 to 4As shown, a fixed support frame 16 is slidably provided on the outer side of the fixed support plate 13. The fixed support frame 16 is fixedly connected to the support base 1 and the top fixed frame 2. An auxiliary top plate 18 that cooperates with the adjusting support plate 4 is fixedly connected to the inner side of the fixed support plate 13. The auxiliary top plate 18 is slidably connected to the fixed support frame 16. A second spring 17 is provided inside the fixed support frame 16. One end of the second spring 17 is connected to the fixed support plate 13.

[0030] It should be noted that in this embodiment, when the output end of the hydraulic cylinder 3 drives the adjusting support plate 4 to move upward, the adjusting support plate 4 pushes the auxiliary top plate 18, and the auxiliary top plate 18 drives the fixed support plate 13 and the first needle plate 12 to move synchronously, and the first needle plate 12 drives the first ejector pin 8 to move and complete the ejection work.

[0031] In one embodiment, such as Figures 1 to 4 As shown, multiple second dampers 25 are symmetrically installed between the adjusting support plate 4 and the mounting plate 5, and a third spring 26 is sleeved on the outside of the second damper 25.

[0032] It should be noted that in this embodiment, the stamping operation of the mounting plate 5 and the upper stamping die 6 is slowed down by the second damper 25 and the third spring 26.

The needle plate 23 is slidably connected to the outside of the top frame 24.

[0034] It should be noted that in this embodiment, the output end of the first hydraulic cylinder 22 drives the second needle plate 23 to slide on the outer side of the top frame 24, and the top frame 24 drives each of the second ejector pins 10 at the bottom to move, and the second ejector pins 10 assist in ejecting the sticking baffle plate on the upper stamping die 6.

[0035] In one embodiment, such as Figures 1 to 4 As shown, multiple dampers 14 are symmetrically installed at the bottom of the support base 1. One end of the damper 14 is connected to the needle plate 12. A spring 15 is sleeved on the outside of the damper 14. A limiting slider 27 is symmetrically fixed to the outside of the limiting support plate 20. The limiting slider 27 is slidably connected to the limiting support box 19.
