Abstract
The utility model discloses a butterfly screw cap formed by cold forging. The butterfly screw cap comprises wing-shaped handles and a screw cap body which are formed by integrated forging and stamping, a through hole is arranged in the screw cap body and internally provided with a thread; the wing-shaped handles are symmetrically arranged at two sides of the screw cap body, from the bottom end of the screw cap body, the wing-shaped handles are upward eccentrically bent into a folded wing shape, the upper end edges of the wing-shaped handles are aligned to the upper edge of the screw cap body, and the lower end edges of the wing-shaped handles are aligned to the lower edge of the screw cap body; the upper end edges of the wing-shaped handles are arranged as an arc shape, the lower end edges of the wing-shaped handles are arranged as a straight line, and the connecting edges between the upper end edges and the lower end edges of the wing-shaped handles are designed as an arc shape. The butterfly screw cap is formed by automatically cutting, forging and stamping, bending, punching, and tapping a round metal wire, and the like, the automation level in processing is high, and operators and the workload of manual carrying and the like in processing procedures can be greatly reduced.
Description
(1) technical field
The utility model relates to a kind of Novel nut, is specifically related to a kind of novel butterfly nut that adopts cold-forge forming.
(2) background technique
Nut is as a kind of the most frequently used machanical fastener, is widely used in people's the every field such as production, life.And on the nut structure body with the Novel nut of wing handle, be a kind ofly can and use very easily nut device not by means of tool operation.Because the nut with wing handle generally relies on casting molding process, manufacturing process wastes time and energy, and reject rate is high.In recent years, along with the development of production technology, quality and the exterior quality of the wing nut that the previous cast molding of greatly having taken on a new look makes the novel wing nut of cold forging punch forming have appearred adopting in a large number, on the market.The utility model provides a kind of whole novel butterfly nut that adopts the cold forging punch forming by further optimizing the manufacturing process of nut.
(3) model utility content
The utility model provides a kind of whole novel butterfly nut that adopts the cold forging punch forming, and main technical schemes is as follows:
A kind of butterfly nut of cold-forge forming comprises wing handle and nut body, and described wing handle and nut body adopt integral type forging and pressing punch forming, are provided with a through hole in the nut body, are provided with screw thread in the through hole; The bilateral symmetry of nut body is provided with wing handle, and upwards and partially bending forming is for rolling over aliform from the nut body bottom for wing handle, and limit, the upper end section of wing handle is mutually neat with the upper edge hole of nut body, and limit, the lower end section of wing handle is mutually neat with the lower bead of nut body; Limit, the upper end section of wing handle is set to arc shape, and limit, the lower end section of wing handle is set to lineal shape, and the fillet between limit, the upper end section of wing handle and limit, the lower end section designs for arc shape.
The butterfly nut of a kind of cold-forge forming described in the utility model, by the circular metal wire rod is cut automatically, the manufacturing procedure such as forging and pressing, bending, punching, tapping, the disposable butterfly nut that makes with wing handle, the automaticity of course of working is high, can reduce in a large number the workloads such as a dead lift of operating personnel and processing link.
(4) description of drawings
