Description

Technical Field

[0001] This utility model relates to the field of frying pan processing technology, specifically a novel frying pan rapid stretching device. Background Technology

[0002] A frying pan is a type of flat-bottomed pan widely used in cooking, especially for frying, stir-frying, and boiling. Its characteristic is its flat bottom, making it suitable for cooking dishes that require less oil and need to maintain a golden-brown, crispy surface. During processing, it is stretched and shaped using a stretching die. In small-batch production, the die is not coated with a special release agent. To prevent the workpiece from sticking to the die, a thin film is placed on the workpiece surface before stamping. This film temporarily acts as a lubricating and isolating medium, ensuring a smooth surface. After stamping, some film debris remains on the die, requiring manual cleaning. This cleaning process is time-consuming and labor-intensive, especially in small-batch production, where frequent cleaning reduces overall production efficiency. Utility Model Content

[0023] 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.

[0024] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a novel rapid stretching device for a frying pan, comprising: a support platform 1; a support plate 4 fixedly connected to the top of the support platform 1, a punch 8 fixedly connected to the top of the support plate 4, a lifting frame 6 slidably connected to the outer side of the punch 8, and a reset part installed at the bottom of the lifting frame 6; a concave mold 9 lifted and positioned above the punch 8, and a push plate 10 for pushing material installed inside the concave mold 9; an air blowing unit positioned on the top of the support platform 1, the air blowing unit comprising a material ejection frame 16 horizontally positioned on the top of the punch 8, and air nozzles 17 and 19 respectively provided at the bottom and top of the material ejection frame 16, both air nozzles 17 and 19 being installed on an air duct, one end of which is connected to the workshop air source via a flexible hose, for cleaning the upper and lower molds while the material ejection frame 16 is discharging material.

[0025] It should be noted that this embodiment is equipped with a PLC controller and corresponding operating switches. During processing, the metal sheet is placed on top of the punch 8, and the die 9 contacts the punch 8 downwards. The die 9 mates with the top of the lifting frame 6, and the cavity inside the die 9 is fitted onto the outside of the punch 8, thereby stretching the metal sheet downwards along the punch 8 to form the shape. When the die 9 moves to its limit position, under the action of the limit switch, the die 9 resets upwards. Under the push of the push plate 10, the material remains on the outside of the punch 8, and under the action of the reset part, the lifting frame 6 resets upwards, thereby placing the formed frying pan on the outside of the punch 8. At the top of the lifting frame 6, when the die 9 is reset, the limit switch is triggered. The switch sends a signal to the PLC controller. After the timer counts, the ejector frame 16 moves laterally and pushes one side of the material box, causing it to slide along the slide groove to one side. During the movement of the ejector frame 16, the first air nozzle 17 blows high-pressure air onto the surfaces of the lifting frame 6 and the punch 8, and the second air nozzle 19 blows air into the interior of the die 9. This cleans the punch 8 and the die 9, reducing the accumulation of metal powder, oil, dust, etc., and preventing dirt from affecting the precision of the mold and production efficiency, and preventing it from affecting the surface quality of the product.

[0026] In one embodiment, a support column is fixedly connected to the top of the support platform 1, a support plate 4 is fixedly connected to the top of the support column, a lifting plate 5 is slidably connected to the outside of the support column, a sliding rod 7 is fixedly connected to the top of the lifting plate 5, the sliding rod 7 is fixedly connected to the lifting frame 6, and a plurality of nitrogen springs 13 are fixedly connected to the top of the support platform 1, the output end of the nitrogen springs 13 is fixedly connected to the lifting plate 5.

[0027] It should be noted that, in this embodiment, when the die 9 moves, the die 9 presses the lifting frame 6 downward along the punch 8. At the same time, the lifting frame 6 drives the slide rod 7 to press the lifting plate 5 downward. While the lifting plate 5 slides on the outside of the support column, it compresses the nitrogen spring 13. The structure of the nitrogen spring 13 adopts the existing setting scheme. For the specific structure, please refer to the patent document of Chinese Utility Model Patent ZL202420690918.2, which has been applied for and published. When the die 9 resets downward, the lifting frame 6 drives the lifting plate 5 to move upward. The lifting plate 5 pushes the lifting frame 6 to reset upward through the slide rod 7.

[0028] In one embodiment, support rods 2 are fixedly connected to the four corners of the top of the support platform 1. A top plate 20 is fixedly connected to the top of the support rods 2. A hydraulic cylinder is fixedly connected to the top of the top plate 20. The output end of the hydraulic cylinder is fixedly connected to the lifting plate 3. The lifting plate 3 is slidably connected to the outer side of the top plate 20. The die 9 is fixedly connected to the bottom of the lifting plate 3. A plurality of limiting rods 11 are slidably connected to the middle of the die 9. The bottom of the limiting rods 11 is fixedly connected to the push plate 10. An ejection spring 12 is sleeved on the outer side of the limiting rods 11 and above the push plate 10.

[0029] It should be noted that in this embodiment, the die 9 moves downward to cooperate with the punch 8, and the workpiece is squeezed and stretched by the gap between the punch 8 and the die 9. During this period, the workpiece squeezes the push plate 10 upward. While applying pressure, the push plate 10 drives the limit rod 11 to move upward and compresses the ejector spring 12. When the die 9 returns to its original position, the ejector spring 12 returns to its original position and drives the push plate 10 to move downward. A limit switch is installed on one side of the top plate 20, and a corresponding metal block is installed on one side of the lifting plate 3. When the hydraulic cylinder drives the lifting plate 3 to return to its original position, the metal block contacts the limit switch. The limit switch transmits a signal to the PLC controller, and the PLC controller controls the corresponding component to work.

[0030] In one embodiment, the blowing unit includes a bracket 14 fixedly attached to the top of the support platform 1, a cylinder 15 fixedly connected to the top of the bracket 14, a ejector frame 16 fixedly connected to the output end of the cylinder 15, a bottom punch 8 of the ejector frame 16 slidably connected to the top, a metal rod slidably connected to the bracket 14 fixedly connected to one side of the ejector frame 16, a bracket 2 18 fixedly connected to the top of the ejector frame 16, and a nozzle 2 19 fixedly connected to the top of the bracket 2 18.

[0031] It should be noted that, in this embodiment, after the lifting plate 3 is reset, the controller controls the cylinder 15 to drive the ejector frame 16 to move forward. By controlling the solenoid valve connected to the nozzle, the ejector frame 16 drives the metal rod to slide in the middle of the bracket 14. The ejector frame 16 contacts the workpiece and pushes it down to one side. The bracket 2 18 has an inclined Z-shaped structure, so that the nozzle 2 19 is located in front of the nozzle 17, so that the nozzle 2 19 blows air upwards. The dust falling on the punch 8 will be blown down by the nozzle 17 behind it. The nozzle 17 cleans the surface of the punch 8, and the nozzle 2 19 blows air to clean the inside of the die 9. The nozzle 17 is inclined so that its air outlet direction is towards the direction of the cylinder 15's movement, so as to blow off the plastic film adhering to the outside of the punch 8.
