Abstract
Description
Technical Field
[0001] This invention relates to the field of material punching technology, and in particular to a punch press with a noise reduction function for shoe sole production. Background Technology
[0002] The punch presses commonly used in shoe sole production are usually referred to in the industry as outsole punching machines or cutting machines. The core function of this type of equipment is to quickly and accurately punch and cut large pieces of shoe sole raw materials, such as rubber, EVA, and leather, into shoe soles of specified shapes.
[0003] Its core working principle is stamping. The equipment is usually hydraulically or mechanically driven, which drives the upper punching mechanism, i.e., the punch or top die, to move downwards and cooperate with the bottom die below to cut the raw material into shape like a stamp. To improve production efficiency, advanced punching machines have continuous automation capabilities. For example, the equipment can automatically feed materials through a chain conveyor system and automatically send the punched shoe soles to the next process, realizing assembly line operation.
[0004] The advantage of this type of equipment lies in its ability to significantly improve production efficiency and product consistency. Compared to traditional manual cutting, mechanical punching is not only faster but also ensures high precision in the size and shape of each shoe sole, thereby reducing the defect rate and guaranteeing product quality. Some equipment also supports quick mold changes to adapt to the needs of producing different styles and sizes of shoe soles.
[0005] The existing punch press is noisy and the material feeding process is prone to jamming, which affects the stable operation of the production line. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 5 As shown, this embodiment provides a punch press with noise reduction function for shoe sole production, including a feeding system 1, a punching system 2, a pulling system 3, a frame 4, a closed pressure hood 5, a punching and shearing system 6, a material collection cart 7, and a pneumatic system 8. The feeding system 1 and the pulling system 3 are respectively installed on both sides of the punching system 2 to realize the material supply of the punching system 2 and the pulling out of the punched tail material. The feeding system 1 includes a feeding device 11, a pushing device 12, and a conveying device 13. The feeding device 11, the pushing device 12, and the conveying device 13 are all installed on the frame 4. The feeding device 11 is used to pick up the material pile piece by piece and place it on the pushing device 12. The pushing direction of the pushing device 12 is from the feeding device 11 to the conveying device 13. The pushing device 12 pushes the whole piece of material to the position of the conveying device 13. The conveying direction of the conveying device 13 is towards the punching system 2. The conveying device 13 realizes the material supply.
[0023] The stamping system 2 has a stamping head 22 and a feeding hole 211 adapted to the stamping head 22. The stamping head 22 punches the material into the feeding hole 211. A closed pressure shroud 5 is installed on the frame 4. The stamping head 22 slides up and down along the inner wall of the closed pressure shroud 5. The closed pressure shroud 5 blocks the noise during stamping on the outside of the stamping head 22, achieving a noise reduction effect. The punching and shearing system 6 is installed on the side of the feeding system 3 away from the stamping system 2, and cuts the tail material into sheet-like pieces. The tail material is divided into sections for easy collection. The collection cart 7 is installed on the lower side of the discharge hole 211 of the stamping system 2 to carry the punched shoe material. The air pressure system 8 is installed on the closed pressure cover 5 and is connected to the inside of the closed pressure cover 5. When the stamping head 22 is in the lower limit position, the air pressure system 8 supplies air to the inside of the closed pressure cover 5. After the stamping head 22 is pressed down to the lower limit position, the air pressure system 8 blows the shoe material out to the lower side of the discharge hole 211 for easy dropping.
[0024] Specifically, the feeding device 11 includes a feeding frame 111, a feeding cylinder 112, and a feeding slider 113. The feeding frame 111 is mounted across the frame 4, and the feeding slider 113 is slidably mounted on the feeding frame 111. The feeding slider 113 is pulled on the feeding frame 111 by a commercially available motor and synchronous belt drive mechanism. The sliding direction of the feeding slider 113 is perpendicular to the pushing direction of the pushing device 12. The sliding of the feeding slider 113 allows the entire piece of material to be transported and placed on the pushing device 12. The end of the feeding cylinder 112 is provided with a suction cup 114. The feeding cylinder 112 is mounted on the feeding slider 113. After the suction cup 114 picks up the material, the movement of the feeding slider 113 and the lifting action of the feeding cylinder 112 pick up the sheet material in the material pile and transport it to the pushing device 12.
[0025] Specifically, the feeding device 12 includes a feeding motor 121, a feeding sliding rod 122, and a feeding plate 123. The feeding plate 123 is slidably mounted on the feeding sliding rod 122, and the feeding motor 121 is mounted on the feeding sliding rod 122. The feeding motor 121 is connected to the feeding plate 123 via a synchronous belt. The sheet material is placed on the feeding plate 123 by the feeding device 11, and the movement of the feeding plate 123 pushes the sheet material toward the feeding device 13.
[0026] Specifically, the feeding device 13 includes a feeding reference plate 131 and several feeding rollers 132. The feeding reference plate 131 is mounted on the frame 4, and each feeding roller 132 is rotatably mounted on the feeding reference plate 131. The feeding direction of the feeding rollers 132 is towards the stamping system 2. After each feeding roller 132 rotates, the sheet material is accurately fed and pushed into the stamping system 2. The accuracy of the punching position can avoid waste.
[0027] Specifically, the stamping system 2 includes a press base 21, a stamping head 22, and a stamping power unit 23. The stamping power unit 23 is mounted on the press base 21 and has a conventional eccentric wheel structure. The stamping power unit 23 is connected to the stamping head 22 for transmission. The stamping head 22 is slidably mounted on the press base 21. The press base 21 is provided with a blanking hole 211. The stamping head 22 is adapted to the blanking hole 211 to realize stamping blanking.
[0028] Specifically, the material pulling system 3 includes a material pulling reference plate 31 and several material pulling rollers 32. The material pulling reference plate 31 is mounted on the frame 4, and each material pulling roller 32 is rotatably mounted on the material pulling reference plate 31. The conveying direction of the material pulling rollers 32 is towards the punching and shearing system 6. After each material pulling roller 32 rotates, the sheet material after punching is conveyed and the tail material is extracted.
[0029] Specifically, the punching and shearing system 6 includes a punching and shearing frame 61, a punching and shearing cylinder 62, and a material discharge frame 63. The punching and shearing cylinder 62 is mounted on the punching and shearing frame 61 by a bracket. The output end of the punching and shearing cylinder 62 is adapted to the punching and shearing frame 61. The output end of the punching and shearing cylinder 62 generates a shearing action with the punching and shearing frame 61 to achieve cutting. The material discharge frame 63 is located on the lower side of the punching and shearing frame 61 to cut and store the tail material for easy reuse.
[0030] Specifically, the pneumatic system 8 includes a pressure accumulator 81 and a vent switch 82. The pressure accumulator 81 is installed on the side wall of the closed pressure hood 5, and the vent switch 82 is installed on the closed pressure hood 5. The closed pressure hood 5 and the pressure accumulator 81 are connected through the vent switch 82. Since the punch head 22 is in contact with the inner wall of the closed pressure hood 5, the airflow has only one outlet, the discharge hole 211. The vent switch 82 opens when the punch head 22 is at its lower limit position, blowing the cut material down through the discharge hole 211. The vent switch 82 points towards the sheet-like material. When the venting switch 82 releases air, the resulting airflow simultaneously blows and shakes the sheet-like material, preventing it from getting stuck in the punch head 22. The pressure storage membrane 81 is connected to a stable air source through an air pipe. The pressure storage membrane 81 stores air as the punch head 22 rises and falls. The external air source stores air in the pressure storage membrane 81 to its maximum when the punch head 22 is at its lower limit position. The function of the pressure storage membrane 81 is to release the stable air source in a concentrated manner when the punch head 22 is at its lower limit position, ensuring that the punched material can fall stably.
