Description

Technical Field

[0001] The invention relates to the technical field of progressive dies, and in particular to a progressive die feeding detection mechanism which is convenient for protecting workpieces. Background Art

[0002] In the process of automatic stamping of product parts on high-speed punch presses, multi-station progressive dies are generally used for stamping. Since multi-station progressive dies have many processes to complete stamping, including blanking, bending, drawing and forming, they are characterized by a large number of stamping steps and a long working range of strips. In order to ensure the stamping quality, the feeding step of the strip must be correct.

[0003] In progressive dies, it is easy for the material strip to be mis-delivered. Manual observation often leads to mis-delivery, which affects the normal operation of the mold and work efficiency. Summary of the invention

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a progressive die feeding detection mechanism which is convenient for protecting the workpiece. The detection mechanism controls the conveying speed of the workpiece through two photoelectric switches, and through detection, the workpiece with inconsistent step distance is adsorbed by the electromagnet, and then the workpiece is put down after it is detected that the step distance reaches the specified distance, thereby completing the entire process. For the workpiece with inconsistent step distance, adsorption treatment is adopted to stop the entry of subsequent workpieces, which neither affects the normal operation of the processing conveyor belt below nor damages the workpiece.

[0005] The present invention is implemented as follows: a progressive die feeding detection mechanism that is convenient for protecting workpieces includes a processing platform and a feeding platform, wherein the feeding platform is fixedly arranged on the left side of the processing platform, baffles are welded on both sides of the upper ends of the processing platform and the feeding platform, a processing conveyor belt is fixedly arranged at the center of the processing platform, a feeding conveyor belt is fixedly arranged at the center of the feeding platform, a first support frame is fixedly arranged at the upper end of the processing platform near the left side, a second support frame is fixedly arranged on the right side of the first support frame, and a plurality of processing punches are fixedly arranged at the right end of the second support frame.

[0006] In order to protect workpieces with inconsistent step distances and not affect the normal operation of the processing conveyor belt, as a preferred progressive die feeding detection mechanism of the present invention that is convenient for protecting workpieces, a telescopic rod is welded to the lower end of the first support frame, and an electromagnetic adsorption block is welded to the lower end of the telescopic rod.

[0007] In order to protect the workpiece from being damaged when the workpiece is adsorbed by the electromagnet, as a preferred progressive die feeding detection mechanism of the present invention that is convenient for protecting the workpiece, a buffer pad is bonded to the lower end surface of the electromagnetic adsorption block.

[0008] In order to block workpieces with inconsistent step distances, as a preferred progressive die feeding detection mechanism of the present invention that is convenient for protecting workpieces, a T-shaped groove is provided on the lower end face of the second support frame, and electric wheels are clamped at both ends of the interior of the T-shaped groove, and the lower ends of the two electric wheels are movably connected to a limiting plate.

[0009] In order to enable the detection device to promptly control other components to process the workpiece with inconsistent step spacing when it detects the workpiece, as a preferred progressive die feeding detection mechanism of the present invention that is convenient for protecting the workpiece, a first photoelectric detection switch is fixedly provided at the center of the lower end of the second support frame near the front side, and a second photoelectric detection switch is fixedly provided on the inner wall of the baffle of the processing platform on the left side of the processing punch press, and the first photoelectric detection switch, the second photoelectric detection switch, the telescopic rod, the electromagnetic adsorption block, the electric wheel and the feeding conveyor belt are electrically connected.

[0010] In order to better adjust the step distance between each workpiece and make the photoelectric detection switch operate better without affecting work efficiency, as a preferred progressive die feeding detection mechanism for protecting workpieces of the present invention, the distance between the second photoelectric detection switch and the second support frame is slightly greater than the length of one workpiece.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This progressive die feeding detection mechanism, which is convenient for protecting workpieces, ensures that the workpieces can enter the processing platform at a certain speed through the feed conveyor belt and baffle, thus avoiding certain errors. When the workpiece is detected by the second photoelectric switch, the limit plate is controlled to move inward to promptly prevent the workpieces with inconsistent step distances from entering. By setting the first photoelectric switch, when the limit plate starts to work, the first photoelectric detection switch also starts to work. When it is detected that the workpieces with inconsistent step distances are approaching, the telescopic rod and the electromagnetic adsorption block are promptly controlled to work to adsorb the workpieces with inconsistent step distances, which neither damages the workpieces nor affects the work of the processing conveyor belt. At the same time, the conveyor belt is also controlled to stop working to avoid more workpieces from entering later, thus the workpieces can be well detected and protected.

[0013] 2. This progressive die feeding detection mechanism is convenient for protecting the workpiece. By setting a buffer pad, when the electromagnetic adsorption block adsorbs the workpiece, the collision and friction between the workpiece and the electromagnetic adsorption block are reduced, thereby avoiding damage to the workpiece and playing a good protective role for the workpiece.

[0021] See also Figure 1-4 A progressive die feeding detection mechanism for protecting workpieces comprises a processing platform 1 and a feeding platform 2. The feeding platform 2 is fixedly arranged on the left side of the processing platform 1. Baffles 3 are welded on both sides of the upper ends of the processing platform 1 and the feeding platform 2.

By setting the baffle 3, processing conveyor belt 5 and feeding conveyor belt 4, the workpiece will not be located during the entire multiple working steps, and the baffle 3 will prevent the workpiece from falling, thereby playing a role in protecting the workpiece.

[0023] As a technical optimization solution of the present invention, a telescopic rod 9 is welded to the lower end of the first support frame 6 , and an electromagnetic adsorption block 10 is welded to the lower end of the telescopic rod 9 .

[0024] In this embodiment, a telescopic rod 9 is welded to the lower end of the first support frame 6, and an electromagnetic adsorption block 10 is welded to the lower end of the telescopic rod 9. Through the set electromagnetic adsorption block 10, workpieces with inconsistent step distances can be adsorbed without damaging the workpieces and affecting the normal operation of the lower end processing conveyor belt 5.

[0025] As a technical optimization solution of the present invention, a buffer pad 11 is bonded to the lower end surface of the electromagnetic adsorption block 10 .

[0026] In this embodiment, a buffer pad 11 is bonded to the lower end surface of the electromagnetic adsorption block 10. When the electromagnetic adsorption block 10 adsorbs the workpiece, the buffer pad 11 reduces the collision between the electromagnetic adsorption block 10 and the workpiece, and also reduces the friction, which can protect the workpiece well during the adsorption process.

[0027] As a technical optimization solution of the present invention, a T-shaped groove 14 is opened on the lower end surface of the second support frame 7, and electric wheels 15 are clamped at both ends of the inside of the T-shaped groove 14, and the lower ends of the two electric wheels 15 are movably connected to the limiting plate 13.

[0028] In this embodiment, a T-shaped groove 14 is provided on the lower end surface of the second support frame 7, and electric wheels 15 are clamped at both ends of the interior of the T-shaped groove 14. The lower ends of the two electric wheels 15 are movably connected to the limit plate 13. When the second photoelectric detection switch 16 detects the workpiece, the electric wheel 15 and the first photoelectric detection switch 12 are controlled to work, so that when they detect that the subsequent workpiece with inconsistent step distance is approaching, they are blocked by the limit plate 13 in time, and the electromagnetic adsorption block 10 is adsorbed in time to make the subsequent workpiece step distance consistent, and continue normal processing.

[0029] As a technical optimization solution of the present invention, a first photoelectric detection switch 12 is fixedly installed at the center of the lower end of the second support frame 7 near the front side, and a second photoelectric detection switch 16 is fixedly installed on the inner wall of the baffle 3 of the processing platform 1 on the left side of the processing punch 8. The first photoelectric detection switch 12, the second photoelectric detection switch 16, the telescopic rod 9, the electromagnetic adsorption block 10, the electric wheel 15 and the feeding conveyor belt 4 are electrically connected.

[0030] In this embodiment, the first photoelectric detection switch 12, the second photoelectric detection switch 16, the telescopic rod 9, the electromagnetic adsorption block 10, the electric wheel 15 and the feeding conveyor belt 4 are electrically connected. When the second photoelectric detection switch 16 detects a workpiece, the electric wheel 15 and the first photoelectric detection switch 12 are controlled to work, so that when they detect that a workpiece with inconsistent subsequent step distances is approaching, they are blocked in time by the limit plate 13. When the first photoelectric detection switch 12 detects a workpiece, the telescopic rod 9 and the electromagnetic adsorption block 10 are controlled to work, and the electromagnetic adsorption block 10 is adsorbed in time. At this time, the feeding conveyor belt 4 is controlled to stop working.

[0031] As a technical optimization solution of the present invention, the distance between the second photoelectric detection switch 16 and the second support frame 7 is slightly greater than the length of a workpiece.

[0032] In this embodiment, the distance between the second photoelectric detection switch 16 and the second support frame 7 is slightly greater than the length of a workpiece. When the second photoelectric detection switch 16 detects the workpiece consistently, the limit plate 13 works. When a workpiece passes through the second photoelectric detection switch 16, the limit plate 13 is restored and the next workpiece enters.

[0033] Working principle: First, turn on the feeding platform 2 and the processing platform 1, and the staff places the workpiece in the center above the feeding conveyor belt 4. The workpiece is conveyed to the top of the processing conveyor belt 5 in turn. When the workpiece moves to the second photoelectric detection switch 16, the second photoelectric detection switch 16 controls the electric wheel 15 and the first photoelectric detection switch 12 to work. When the subsequent workpiece has inconsistent step lengths and enters the processing conveyor belt 5 in advance, the electric wheel 15 drives the limit plate 13 to move to the middle to block the subsequent workpiece. At this time, the first photoelectric detection switch 12 detects the workpiece and controls the telescopic rod 9 and the electromagnetic adsorption block 10 to work to adsorb the subsequent workpieces with inconsistent step lengths. At the same time, the feeding conveyor belt 4 is controlled to stop feeding. When the workpiece detected by the second photoelectric detection switch 16 passes, the second photoelectric detection switch 16 cannot detect the workpiece at this time, and then controls the electric wheel 15. The wheel 15 and the first photoelectric detection switch 12 are in the closed working state. At this time, the telescopic rod 9 and the electromagnetic adsorption block 10 stop working, so that the subsequent workpiece falls and continues to enter the processing punch 8 for processing. When the telescopic rod 9 and the electromagnetic adsorption block 10 stop working, the feeding conveyor 4 continues to be controlled to resume working. Through the first photoelectric detection switch 12, the second photoelectric detection switch 16, the telescopic rod 9, the electromagnetic adsorption block 10, the electric wheel 15, and the feeding conveyor 4, the entire progressive die can detect the workpiece in time during the processing process. When inconsistent step distances are detected, they are processed in time, and the buffer pad 11 is set and the electromagnet adsorption method is adopted to protect the workpiece from damage and does not affect the operation of the processing conveyor 5.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
