Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and specifically relates to a blanking device for a punching machine. Background Art

[0002] A blanking device for a punching machine is a special equipment used to receive and process parts or waste generated after punching machine processing. It is usually used in conjunction with the punching machine equipment and is located at the discharge port of the punching machine. It is responsible for automatically receiving the parts or waste ejected from the punching die and performing subsequent processing such as classification, counting, conveying, or stacking.

[0003] The existing blanking devices for punching machines usually consist of a frame part, a transmission system, and a blanking plate. The frame part is the supporting structure of the entire blanking device and is usually made of heavy cast iron to ensure that it can withstand high loads and vibrations during operation and provide a stable working platform. The electric motor serves as the power source and transmits power to other parts of the blanking device through a transmission system such as belts, gears, etc. to drive the operation of the entire device. The blanking plate is the component that directly receives the parts or waste ejected from the punching machine, and its design usually takes into account the size, shape, and weight of the parts to ensure that the parts can accurately and smoothly fall into it.

[0004] Although the existing blanking devices for punching machines have made significant progress in terms of automation and efficiency, there are still some disadvantages. There is still room for improvement in terms of intelligence. For the functions of counting and identifying parts, the current devices still require manual intervention or rely on simple sensors and cannot achieve a higher level of intelligent management and control. For some parts with high-precision requirements, the existing blanking devices for punching machines may not be able to fully guarantee the accuracy of the parts during the blanking process. Due to factors such as vibration and impact during the blanking process, the parts may undergo slight deformation or displacement, thereby affecting their quality and performance. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing blanking device, it solves the problems that due to the insufficient accuracy of the blanking plate during use, vibration and impact factors will cause slight deformation or displacement of the parts, thereby affecting their quality and performance, as well as the current insufficient intelligence level, inability to count and identify the produced parts, and the waste of cost caused by the need for manual intervention. The structure of the blanking device is relatively complex, and it is more difficult to adjust and maintain. This also leads to the need to spend a long time and effort on repair and adjustment when a failure or problem occurs during the production process, affecting production efficiency and cost.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A material receiving device for a punching machine according to the present utility model includes a bottom plate.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] The following gives specific embodiments.

[0022] Please refer to Figures 1 - 4 , a material receiving device for a punching machine according to the present invention, characterized in that: it includes a bottom plate 1, a punching table 3 is arranged in the middle of the top surface of the bottom plate 1, the punching table 3 is fixed by fixing screws, a housing 2 is installed on one side of the bottom plate 1, the housing 2 is hollow inside, a upper connecting block 101 is fixedly arranged on the lower bottom surface of one side of the housing 2, a connecting rod 22 is arranged inside the upper connecting block 101, the connecting rod 22 is fixed by an upper pin 201, the other end of the connecting rod 22 is fixedly installed with a material receiving plate 24, a lower connecting block 102 is fixedly installed on one side of the bottom surface of the slider 7, a linkage rod 26 is installed inside the lower connecting block 102, the lower connecting block 102 is fixed by a lower pin 202. During operation, when the slider 7 moves upward, it will drive the forward movement of the linkage rod 26, thereby driving the movement of the material receiving plate 24 to receive materials. When the slider 7 moves downward, it drives the linkage rod 26 to move outward, thereby pushing the material receiving plate 24 to discharge materials outward.

[0023] Further, a driven wheel 16 is fixedly installed on one side of the box body 2. A belt 17 is arranged on the surface of the driven wheel 16. A motor 18 is fixedly installed on one side of the base 1. A driving wheel 27 is fixed to the output end of the motor 18. A belt 17 is arranged on the surface of the driving wheel 27. The driving wheel 27 and the driven wheel 16 are driven by the belt 17. On one side inside the outer shell 2, a turntable 15 is fixedly installed. A fixing block 14 is installed on the top of the turntable 15. On the other side top surface of the fixing block 14, a movable shaft 13 is connected. One end of the movable shaft 13 is connected with a mounting block 12. The bottom surface of the mounting block 12 is a plane. A linkage shaft 11 is fixedly installed on the bottom surface of the mounting block 12. A telescopic shaft 10 is installed at the bottom of the linkage shaft 11. A shaft sleeve 9 is fixedly arranged on the bottom surface of the telescopic shaft 10. A slider 7 is fixedly connected to the bottom surface of the shaft sleeve 9. Slide plates 8 are arranged on both sides of the slider 7. Chute grooves 19 are arranged on both sides inside the outer shell 2. The slide plates 8 move inside the chute grooves 19. A hydraulic rod 6 is arranged at the bottom of the slider 7. A punching clamping plate 5 is fixedly installed at the bottom of the hydraulic rod 6. During operation, when the motor 18 is powered on, the driving wheel 27 at the output end rotates, driving the belt 17 to rotate and also driving the rotation of the driven wheel 16 at the same time. The connecting rod of the driven wheel 16 penetrates through the turntable 15 installed inside the outer shell 2 and also starts to rotate. The rotation of the turntable 15 drives the connected fixing block 14 to rotate, thereby driving the rotation of the movable shaft 12. Subsequently, the mounting block 12 also rotates to drive the fixedly installed linkage shaft 11 below to rotate. Along with the rotation of the linkage shaft 11, the telescopic shaft 10 arranged below also starts to move, thereby driving the up and down movement of the slider 7. The movement of the slider 7 is the cooperation of the slide plate 9 sliding inside the chute groove 19 and the telescopic shaft 10. The movement of the slider 7 can be transmitted to the punching clamping plate 5 arranged below the slider 7, and then the punching of the object is carried out.

[0024] Further, a rotating shaft is rotatably installed on the side wall of the outer shell 2. One end of the rotating shaft is installed with a driven wheel 16. A motor 18 is fixedly installed on the top side of the bottom plate 1. A driving wheel 27 is fixed to the output end of the motor 18. The driving wheel 27 and the driven wheel 16 are in transmission connection through a belt 17. On one side of the base 1, a counter base 28 is fixedly installed on the same side as the receiving plate 24. A counter 29 is arranged on the top surface of the counter base 28. A material discharging hole 29 is opened on one side of the receiving plate 24. During operation, when the receiving plate 24 starts to receive materials, the received standard parts are pushed out from the material discharging port 28. When the standard parts pass through the receiving plate 24, the counter 28 starts to count the number of standard parts passing through.

[0025] Working principle: When the motor 18 is powered on, the driving wheel 27 at the output end rotates, driving the belt 17 to rotate. At the same time, it also drives the rotation of the driven wheel 16. The connecting rod of the driven wheel 16 passes through the inside of the housing 2 and the rotating disc 15 installed also starts to rotate. The rotation of the rotating disc 15 drives the connected fixed block 14 to rotate, thereby driving the rotation of the movable shaft 12. Subsequently, the mounting block 12 also rotates to drive the fixed linkage shaft 11 below to rotate. With the rotation of the linkage shaft 11, the telescopic shaft 10 provided below also starts to move, thereby driving the up and down movement of the slider 7. The movement of the slider 7 is the cooperation of the sliding plate 9 sliding in the chute 19 and the telescopic shaft 10. The movement of the slider 7 can be transmitted to the punching clamp plate 5 provided below the slider 7, and then the object is punched. When the slider 7 moves upward, it will drive the connecting rod 26 to move forward, thereby driving the receiving plate 24 to move for receiving materials. When the slider 7 moves downward, it drives the connecting rod 26 to move outward, thereby pushing the receiving plate 24 to discharge materials outward. When the receiving plate 24 starts to receive materials, the standard parts caught are pushed out from the material discharge port 28. When the standard parts pass through the receiving plate 24, the counter 28 starts to count the number of standard parts passing through.
