Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

In the description of the present utility model, it should be noted that the positional relationship indicated by the terms "above", "below", etc. are based on the positional relationship shown in the drawings, and are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1 to 2, the present utility model is directed to a spring chamfering structure comprising an upper die and a lower die used in combination with the upper die. The upper die comprises an upper die holder 10, an upper cushion block 12 and an upper clamping plate 14 which are arranged below the upper die holder 10, and a punch 16 which is arranged below the upper die holder 10 and is connected with the upper cushion block 12. The lower die comprises a lower die holder 18, a lower base plate 20 and a lower die plate 22 which are arranged above the lower die holder 18, and a female die insert 24 which is arranged on the lower base plate 20 and penetrates through the lower base plate 20 to the upper die plate 22, wherein the position of the female die insert 24 is arranged below the position of the punch 16. Lower stripper plate 50 is disposed between upper clamp plate 14 and lower die plate 22.

Wherein, a guide punch 26 is arranged in the punch 16, and the guide punch 26 is arranged on the upper backing plate 12. The bottom of the pilot punch 26 extends from the punch 16 to pre-guide the product 48 as the upper die holder 10 is depressed, ensuring perpendicularity of the product 48.

The outside of die insert 24 is provided with briquetting 28, and briquetting 28 sets up on lower bolster 22 and blocks die insert 24 for fixed die insert 24. The cavity 30 is arranged in the female die insert 24, the chamfering punch 32 can penetrate into the cavity 30 in the female die insert 24 from the bottom, and the cavity 30 can limit the chamfering punch 32. The pilot punch 26 and the chamfering punch 32 are on the same axis, and a through groove 38 for making the bottom of the pilot punch 26 go deep into the chamfering punch 32 is formed in the chamfering punch 32.

The chamfering punch 32 is provided at the top with a recess 40 for chamfering the product 48. The bottom of the chamfering punch 32 is connected with a push rod 34, and a nitrogen spring 36 for driving the push rod 34 to drive the chamfering punch 32 to move is connected below the push rod 34. The nitrogen springs 36 are disposed on the lower plate 42 by spring blocks 46, and the lower plate 42 is disposed below the lower die holder 18 and connected to the lower die holder 18 by lower legs 44.

In use, the nitrogen spring 36 provides a buoyancy force to the chamfering punch 32, and the product 48 is chamfered in a clamp-to-clamp manner by the punching force of the upper die and the force of the nitrogen spring 36. The chamfering action is not instantaneous and is a continuous process due to the travel of the nitrogen spring 36 itself. When the workpiece initially contacts the product 48, chamfering is started, so that the product 48 is continuously stressed and is not influenced by whether the die is closed or not, the problem that chamfering cannot be performed or the workpiece is overturned is avoided, the chamfering is more stable, and the product 48 is not deformed due to the fact that the chamfering is excessive.

The utility model is more visual to show the utility model point, omits the connecting pieces such as bolts for connecting the lower release plate 50, and the omitted connecting pieces can be self-supplemented by a person skilled in the art according to the mastered technical knowledge.
