[0001] The present application relates to the technical field of forming machines, in particular to an automatic blanking forming machine with waste self-cleaning function. BACKGROUND

[0002] In the operation process of the automatic blanking forming machine, waste treatment has always been a key problem affecting the operation efficiency of the equipment and the product quality.

[0003] However, in the blanking process of the existing traditional blanking forming machine, the blade edge is prone to adhere to waste. If these waste is not cleaned in time, it will repeatedly rub against the workpiece and the die with the blanking action, resulting in a decrease in product precision and an increase in die wear. At the same time, fine waste is also prone to accumulate in the concave cavity, affecting the continuity and stability of subsequent blanking. Therefore, manual cleaning is often required frequently, which affects the production efficiency and cannot realize the automatic treatment of waste from generation to collection.

[0013] The beneficial effects of the present invention are: 1.

Since the scraper is in contact with the surface of the punch edge, the lifting frame and the scraper will move downward with the punch during punching and be limited by the die during the punching process. The fixed ring on the output end of the electric cylinder will compress the reset spring when it moves downward. When the output end of the electric cylinder shrinks and moves upward after punching, the reset spring automatically rebounds when it is reset, prompting the scraper to scrape off the waste material adhered to the punch edge. 2.

When the sliding box moves, the cleaning brush head is also driven by the movable rod to move left and right in the molding groove, so that the waste in the molding groove can be cleaned left and right; at the same time, the negative pressure collection pump cooperates with the work to better collect the negative pressure when cleaning the waste in the molding groove, so that the molding groove is cleaned more thoroughly; 4. In the present invention, the rotating wheel is driven by a driving motor to rotate. When the rotating wheel rotates, the roller vibrates and strikes the vibrating spring back and forth. At the same time, the movable block compresses the vibrating spring and resets it by the vibrating spring. The vibrating spring also vibrates the waste collection funnel during the vibration striking process. This can prevent the waste from being retained in the waste collection funnel due to static electricity or viscosity, thereby further preventing the accumulation of waste in the waste collection funnel during the unloading process. To sum up, the present invention can not only avoid the situation where the cutting edge of the punching and forming die is easily adhered to waste during punching, but also automatically clean up the cleaned waste in time, which is conducive to ensuring the continuity and stability of subsequent punching; and the waste is automatically cleaned from the residue in the mold to the final collection and storage throughout the entire process without the need for manual intervention; at the same time, the cleaning action is linked with the punching action, which does not affect the normal rhythm of the equipment and greatly improves production efficiency; reduces the impact of waste accumulation on mold accuracy and work surface, reduces equipment failure rate, and ensures better overall use effect.

[0021] The vibration spring 801 is an overall arched structure. A rolling groove 151 is provided on the circumference of the rotating wheel 15 , and the roller 152 is rollingly installed in the rolling groove 151 .

[0022] like Figure 5 In the embodiment, a second guide slider 20 is provided on the top of the movable block 13 , a second guide rail 19 is provided on the top inner wall of the installation cavity 100 , and the second guide slider 20 is slidably installed on the second guide rail 19 along the horizontal direction.

[0023] like Figure 3 In the embodiment, vertical sliders 124 are fixedly provided on the inner walls on both sides of the movable ring 123, and vertical slide grooves 126 are symmetrically provided on the output end of the electric cylinder 4. The vertical sliders 124 are slidably installed in the vertical slide grooves 126 along the vertical direction.

[0024] Among them, an opening 101 is provided on the front side of the punching and forming machine 1, and the opening 101 is located on the front side of the waste collection box 11, and a door panel 102 is rotatably hinged on the opening 101; a controller 103 is provided on the front side of the punching and forming machine 1, and the controller 103 is electrically controlled and connected with the electric cylinder 4, the negative pressure collection pump 9, the stepper motor 181 and the drive motor 14.

[0025] like Figure 1-7In use, the output end of the electric cylinder 4 is used to drive the mounting frame 5 and the punching and forming punch 6 to move downward, and then the punching and forming punch 6 and the blade cooperate with the forming groove 701 on the die 7 to perform punching and forming on the workpiece. Since the scraper 121 is in contact with the cutting edge surface of the punch 6, the lifting frame 12 and the scraper 121 will move downward with the punch 6 during punching and be limited by the die 7 during the punching process. The fixing ring 127 on the output end of the electric cylinder 4 will compress the reset spring 125 when it moves downward. When the output end of the electric cylinder 4 shrinks and moves upward after punching, , driving the punching and forming punch 6 and the lifting frame 12, L-shaped bracket 122, and movable ring 123 to move upward as a whole. At the same time, the reset spring 125 automatically rebounds when it is reset, and prompts the scraper 121 to scrape off the waste material adhering to the cutting edge of the punch 6, and then the waste material falls into the forming groove 701; at the same time, a negative pressure channel 702 is opened at the bottom of the forming groove 701. After the punching is completed, the negative pressure collection pump 9 is started, and the scraped fine waste material is sucked into the negative pressure channel 702 through the airflow to avoid the waste material from accumulating in the forming groove 701, and then collected into the waste collection box 11.

[0026] As a further step, when the punching is completed, the stepper motor 181 can also be used to drive the worm 182 to rotate and engage with the worm gear 183, thereby driving the threaded barrel 184 to rotate, so that the sliding box 18 can be threaded to the left or right based on the fixed screw 185 through the threaded barrel 184. When the sliding box 18 moves, it also drives the cleaning brush head 187 to move left and right in the molding groove 701 through the movable rod 186, so that the waste in the molding groove 701 can be cleaned left and right; at the same time, it cooperates with the negative pressure collection pump 9 to better collect the negative pressure when cleaning the waste in the molding groove 701, so that the molding groove 701 is cleaned more cleanly.

[0027] At the same time, when the waste is discharged from the waste collection funnel 8, the driving motor 14 can also drive the rotating wheel 15 to rotate. When the rotating wheel 15 rotates, the roller 152 will vibrate and knock the vibrating spring 801 back and forth. At the same time, the movable block 13 will also compress the vibrating spring 16 and use the vibrating spring 16 to reset it. The vibrating spring 801 will also vibrate the waste collection funnel 8 during the vibration knocking process. This can avoid the waste from being retained in the waste collection funnel 8 due to static electricity or viscosity, so as to further prevent the accumulation of waste during the discharge process of the waste collection funnel 8. Ultimately, the present invention can not only avoid the situation where the cutting edge of the punch 6 is prone to sticking to waste during punching, but also automatically clean up the cleaned waste in a timely manner, avoiding the disadvantages of frequent manual cleaning in the past, which is conducive to ensuring the continuity and stability of subsequent punching, and making the use effect of waste from generation to collection better.
