Description

Technical Field

[0001] The utility model relates to the technical field of punching sheet material processing, and more specifically to a punching detection device for a punching machine. Background Art

[0002] The existing continuous high-speed punching machines do not adopt punching detection methods during the stamping production process. Needle breakage and failure to punch may occur during the use of high-speed continuous punching machines. No monitoring feedback is performed during the production process. After the stamping is completed and the coil is formed, spot checks cannot be performed. If continuous holes or failure to punch will occur, they will flow directly to end customers, affecting product quality. Utility Model Content

[0005] A punching detection device for a punching machine comprises a divider and a detection piece. The divider is connected to a die on the punching machine. The divider provides an intermittent pulling force to the die so that the punching holes on the die pass through the detection piece in sequence. The detection piece is used to detect the punching holes.

[0006] Furthermore, it also includes a pin wheel, and the pin wheel is sleeved on the output shaft of the divider.

[0007] Furthermore, it also includes a sensing component, which includes a sensing plate fixing ring, a sensing plate and a photoelectric sensor. The sensing plate fixing ring is located on the divider, and the sensing plate fixing ring is sleeved on another output shaft of the divider. The photoelectric sensor is always clamped on the edge of the sensing plate.

[0008] Furthermore, the detection component includes an optical fiber fixing seat and a round hole detection optical fiber and a square hole detection optical fiber located on the optical fiber fixing seat.

[0009] Furthermore, the detection member also includes an adjustment plate, and the adjustment plate is used to adjust the position of the optical fiber fixing seat.

[0010] Furthermore, a dust removal throttle valve with its opening facing the punching hole of the mold is also provided below the optical fiber fixing seat.

[0011] The beneficial effects of the utility model are as follows: by arranging the cooperation of the divider, the needle wheel and the sensing part, when the sensing sheet in the sensing part rotates one circle, the corresponding needle wheel rotates one interval so that the mold on the punch press drives a hole tool, and then the round hole detection optical fiber and the square hole detection optical fiber are used to detect the hole of the current mold, that is, the quality of the punching material can be detected during the high-speed stamping process, and the machine can be shut down in time and a warning signal can be given in case of abnormality, so as to prevent and repair in time.

DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] Since the existing continuous high-speed punching machine does not adopt punching detection means during the punching production process, the high-speed continuous punching machine may break the needle or fail to punch through. No monitoring feedback is performed during the production process. After the punching is completed and the coil is formed, spot checks cannot be performed. If there are continuous holes or failure to punch through, the coil will flow directly to the end customer, affecting the product quality. Therefore, the utility model relates to such a punching detection device for a punching machine, such as Figure 1 and Figure 2As shown, it includes a splitter 1 and a detection part. The splitter 1 is connected to the mold on the punching machine. The splitter 1 provides an intermittent pulling force to the mold so that the punched holes on the mold pass through the detection part in sequence. The detection part is used to detect the punched holes. Specifically, it also includes a pinwheel 2 and a sensing part. The pinwheel 2 is mounted on the output shaft of the splitter 1. The sensing part includes a sensing plate fixing ring 3, a sensing plate 4 and a photoelectric sensor 5. The sensing plate fixing ring 3 is located on the splitter 1. The sensing plate fixing ring 3 is mounted on another output shaft of the splitter 1. The photoelectric sensor 5 is always clamped on the edge of the sensing plate 4. When the splitter 1 rotates, it drives the pinwheel 2 to do intermittent motion. Every time the splitter 1 starts and stops, the sensing plate 4 fixed on the sensing plate fixing ring rotates 360 degrees. When the photoelectric sensor 5 detects that the sensing plate 4 rotates one circle, the mold on the machine tool is pulled back a punching distance. The detection part includes an optical fiber fixing seat 6 and The round hole detection optical fiber 7 and the square hole detection optical fiber 8 are located on the optical fiber fixing seat 6. The detection part also includes an adjustment plate 9. The adjustment plate 9 is used to adjust the position of the optical fiber fixing seat 6 so that the punching material and the detection optical fiber position match each other. The round hole detection optical fiber 7 detects whether there is a broken hole or a connected hole at the position of the punching hole of the splitter 1 when the splitter 1 is stationary. The square hole detection optical fiber 8 counts and compares the number of square holes detected by the square hole detection optical fiber 8 within one rotation cycle of the splitter 1. A dust removal throttle valve 10 with an opening facing the punching hole of the mold is also provided below the optical fiber fixing seat 6. The dust removal throttle valve 10 can perform air flushing on the top of the mold to remove impurities and dust from the surface, thereby improving the detection accuracy of the optical fiber.

[0017] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
