Problems solved by technology

[0004] The common problem of this punching method is that the worker’s work efficiency is low, the manual punching speed is slow, and the manual punching position is often not accurate enough, often after punching, it is found that the punching position is interfered by other parts of the material belt and cannot be used. The problem is that manual punching is time-consuming and labor-intensive, and the labor co...

Method used

As shown in accompanying drawing 6 to 8, described punch tip 323 has the bevel 3231 that is arranged obliquely with punch 32 length direction, described bevel 3231 and the joint of punch tip 323 peripheral surface are provided with anti- Crack impact surface 3232. The anti-crack impact surface 3232 is a flat or arc-shaped surface, and the width of the anti-crack impact surface 3232 is 0.1 to 1 mm. The anti-cracking impact surface 3232 is the part where the punch 32 first touches the material belt when punching. Although the traditional sharp point like a knife edge is easier to penetrate the material belt with less force, its structure is thin and fragile, and it is easy to repeat. After use, it cracks and the life is short, which increases the loss and man-hours during operation. However, the anti-cracking impact surface 3232 of the present invention adopts a small-area tip with a certain width, which has better structural strength and can basically not increase the perforation resistance. Under the circumstances, the reliability of the punch is greatly improved and the service life is extended, thereby significantly redu...

Abstract

The invention discloses a punching device of a numerical control enclosed machine. The punching device is driven by adopting a stepping motor and a multi-connecting-rod force-increasing structure, sothat the punching is fast, reliable and convenient to use, the punching device is combined with a traditional enclosed machine, punching and grooving of material straps can be completed on the enclosed machine at one step, the punching is fast, the punching position control is accurate and the hole molding is accurate, the molding is performed through primary punching, secondary machining is not needed, so that the efficiency is greatly improved, and the labor cost is reduced; and the punching device is simple in structure, reliable in operation, small in equipment size and capable of accurately controlling the punching position, the speed is faster and more accurate, thus the efficiency is improved, and the cost is reduced.

Example Embodiment

[0029] Example: as attached Figure 1 to 5 As shown, a punching device for a numerically controlled encircling machine includes a mounting frame 1, which is provided with a punching drive device, a punching component 3, and a punching backing plate 4, and the punching component 3 includes a punch The punch 32 and the punch mounting seat 31 are mounted on the punch mounting seat 31, the punching backing plate 4 is provided with a punch through hole 41 and a material belt through groove 42, and the punch through The hole 41 vertically penetrates the belt through slot 42, the end of the punch 32 away from the punch mounting seat 31 extends into the punch through hole 41, and the punching driving device drives the punching component 3 toward the punching backing plate 4 Linear reciprocating motion.

[0030] As attached Figure 6 to 8 As shown, the punch 32 includes an integrated punch tail 321, a punch rod 322 and a punch tip 323, the diameter of the punch tail 321 is larger than the diameter of the punch rod 322, and the punch mounting seat 31 is provided with a punch installation groove 311, the cross section of the punch installation groove 311 is T-shaped, and the punch end 321 is sleeved in the punch installation groove 311.

[0031] As attached Figure 6 to 8 As shown, the punch tip 323 has an inclined surface 3231 arranged obliquely to the length direction of the punch 32, and a crack preventing impact surface 3232 is provided at the junction of the inclined surface 3231 and the outer peripheral surface of the punch tip 323. The anti-cracking impact surface 3232 is a flat or curved surface, and the width of the anti-cracking impact surface 3232 is 0.1 to 1 mm. The anti-cracking impact surface 3232 is the part where the punch 32 first touches the strip when punching. Although the traditional sharp point like a knife edge is easier to penetrate the strip with less force, its structure is thin, fragile and easy to repeat. It cracks after use and has a short service life, which increases the loss and working hours during operation. The anti-cracking impact surface 3232 of the present invention adopts a small area tip with a certain width, which has better structural strength and can basically not increase the perforation resistance. Under the circumstances, the reliability of the punch is greatly improved and the service life is extended, thereby significantly reducing the loss during operation and avoiding the labor cost of frequent replacement of the punch.

[0032] As attached Figure 1 to 5 As shown, the mounting frame 1 is provided with a backing plate mounting seat 5, the backing plate mounting seat 5 includes two side wing mounting plates 51 fixedly installed on the mounting frame 1, and the punching backing plate 4 is provided with A backing plate installation groove 44, the punching backing plate 4 is screwed to the backing plate mounting seat 5 through the backing plate installation groove 44, and the height of the punching backing plate 4 is adjusted through the backing plate installation groove 44. The bolts used for fixing are not shown in the drawings.

[0033] The punching backing plate 4 is provided with a waste recess 43 at one end away from the punch 32, and the waste recess 43 is in communication with the punch through hole 41. The mounting frame 1 is provided with a waste material through hole 101, the waste material through hole 101 is located under the waste material recess 43, the small wafer waste generated by the punch 32 punching through the waste material recess 43 and the waste material through hole 101 falls below the equipment , To prevent the accumulation of waste materials on the equipment and affect the operation.
