Abstract

A tensile type flanging nut relates to a fixing part, particularly to a fixing nut. The tensile type flanging nut comprises a cylindrical body which presents a three-layer structure from the interiorto the exterior; a threaded cylinder with a screw thread is arranged in the inner layer, a stretching cylinder without a screw thread is arranged in the outer layer, and a space cylinder is arranged between the threaded cylinder in the inner layer and the stretching cylinder in the outer layer; the threaded cylinder in the inner layer and the stretching cylinder in the outer layer adopt an integral structure formed entirely, and the threaded cylinder in the inner layer is flanged and bent and finally encircled in the stretching cylinder in the outer layer; the threaded cylinder in the inner layer is provided with an internal thread and an external thread which correspond to each other, namely, the internal thread of the threaded cylinder in the inner layer is raised to appear on the outerwall of the threaded cylinder, so as to form the corresponding external thread thereof; the internal thread and the external thread are formed at one time through the thread rolling operation of the mould; and an anti-slip groove is arranged on the outer wall of the stretching cylinder in the outer layer. The utility model has the benefits of simple processing technique, labor and time conservation, energy consumption, convenient use and good fixing effect.

Description

A kind of drawing flange nut

Technical field

The utility model relates to a kind of fixed block, especially a kind of set screw nut.

Background technique

Set screw nut is the requisite fixed blocks of the parts of various electrical equipment.Set screw nut and the double-screw bolt that cooperates with it match, and for example a certain parts can be fixed on the electrical equipment.Traditional set screw nut profile is generally hexahedron, is convenient to cooperate with fastening instrument; Its inwall has been attacked thread, is called internal thread (internal screw thread).In the prior art, generally by lathe car system, operation is numerous and diverse in the making of the internal thread of set screw nut, and it is consuming time to take a lot of work, and a slight set screw nut, the time cost of its making are but very high.

A kind of processing technology of market demand is simple, in light weight, consumptive material is few, cost low and set screw nut easy to use.

The model utility content

The utility model is intended to the above-mentioned deficiency and the market demand at prior art, releases a kind of drawing flange nut.It has, and processing technology is simple, in light weight, consumptive material is few, cost low and characteristics easy to use.Not only can strengthen its market competitiveness, also be beneficial to and save valuable non-renewable metals resources, promote sustainable development.

In order to finish above-mentioned task, realize above-mentioned purpose, a kind of drawing flange nut of the utility model adopts following technological scheme:

A kind of drawing flange nut of structure the utility model, comprise body cylindraceous, described body is three layers of tubular structure from inside to outside, and internal layer is the thread barrel with screw thread, outer for there not being the stretching tube of screw thread, be the space tube between the described thread barrel of internal layer and the outer field described stretching tube; The integrative-structure that the described thread barrel of internal layer and outer field described stretching tube are global formation, the described thread barrel flange bending of internal layer stretches to be enclosed and is placed in outer field described stretching tube; The described thread barrel of internal layer is shaped on internal thread and the outside thread that corresponds to each other, and promptly the internal thread of the described thread barrel of internal layer protrudes the outer wall that is revealed in described thread barrel becomes its corresponding outside thread.

Technique scheme is further set forth:

Described internal and external screw thread rolls tooth by mould and forms single forming.

The outer wall of outer field described stretching tube is shaped on anti-slip tank, and hand can increase friction when twisting, and prevents from that hand from twisting to skid, and is convenient to hand and twists turn.

1., stretch flanging the utility model is compared with prior art, and its beneficial effect is: one, processing technology are simple, are divided into for three steps:; 2., roll tooth; 3. bending stretches.Three steps link up and operate, and accomplish without any letup, and are simple to operate, saving of work and time, and the car system when no longer needing to consume expenses of labour can reduce the production and processing cost greatly.Two, energy-saving and cost-reducing in the processing, screw thread of the present utility model is by the stretching rolling, and single forming not only can reduce labor intensity, also can energy efficient.Three, the utility model is thinner than the nut wall of existing car system annular knurl, and it is light that its weight is wanted, and can save valuable non-renewable metals resources.Simultaneously,, can also alleviate the weight of product, improve Security because weight saving not only is convenient to install.Its four, the outer wall of outer field described stretching tube is shaped on anti-slip tank, hand can increase friction when twisting, and prevents from that hand from twisting to skid, and is convenient to hand and twists turn.Its five, whole sight property is good because described body is three layers of tubular structure from inside to outside, it is solid to seem on the whole, has eliminated by thin, light and shaky sense that produce.Six, easy to use, what be used for fixing is effective.Seven, suitability is good, be convenient to cooperate with screw rod, thereby, of many uses, be applicable to multiple occasion.

Embodiment

Below, in conjunction with the accompanying drawings, introduce embodiment of the present utility model.

As shown in Figure 1, 2, a kind of drawing flange nut of structure the utility model, comprise body 1 cylindraceous, described body 1 is three layers of tubular structure from inside to outside, internal layer is the thread barrel 2 with screw thread, outer for there not being the stretching tube 3 of screw thread, be space tube 4 between the described thread barrel 2 of internal layer and the outer field described stretching tube 3; The described thread barrel 2 of internal layer and outer field described stretching tube 3 are the integrative-structure of global formation, and the described thread barrel 2 flange bendings of internal layer stretch to be enclosed and are placed in outer field described stretching tube 3; The described thread barrel 2 of internal layer is shaped on internal thread 5 and the outside thread 6 that corresponds to each other, and promptly the internal thread 5 of the described thread barrel 2 of internal layer protrudes the outer wall that is revealed in described thread barrel 2 becomes its corresponding outside thread 6.

The described internal thread 5 of described thread barrel 2 and outside thread 6 roll tooth by mould and form single forming.

The outer wall of outer field described stretching tube 3 is shaped on anti-slip tank 7, and hand can increase friction when twisting, and prevents from that hand from twisting to skid, and is convenient to hand and twists turn.
