Abstract
The utility model discloses a batch punforming screw thread hole by mold, comprising an inner hole, wherein, a cut communicated with the inner hole is arranged at the edge of the inner hole and the two sides of the cut are respectively provided with the head and the end of the screw thread. The screw hole in the utility model can be formed by punching in batch through dies without the process of artificial tapping and greatly improves the production efficiency of finished goods; In addition, the screw hole formed by punching by molds with no burr is guaranteed safety, completely eliminating the defect of tap missing during the course of artificial tapping .The screw hole can completely substitute the normal screw thread hole on the metal plank stuff.
Description
Technical field
The utility model relates to a kind of tapped hole, refers more particularly to a kind of tapped hole that is opened on the sheet metal.
Background technique
Being threaded is a kind of common Placement, and this Placement has made things convenient for the installation and removal between each need parts.It is that internal and external threads by cooperatively interacting realizes that said internal thread is exactly a tapped hole here that what is called is threaded, and it comprises: endoporus and the screw thread that adapts with it.At present, on sheet metal, offer tapped hole,, normally on sheet metal, stamp out endoporus, the flange tapping that punching press is formed then, formation tapped hole in order to save cost.Obviously, contain too many burr in the tapped hole of Xing Chenging like this, in the assembling of component and unloading process, be easy to damage to the operator; And because the screw thread in this internal thread all comes by artificial tapping tapping one by one, efficient is extremely low, but also the phenomenon of attacking takes place to leak easily, forms " bald " hole that does not have screw thread.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of by the stamping forming tapped hole of mould batch.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of tapped hole comprises: endoporus, the edge of described endoporus are provided with an otch that connects with endoporus, and the both sides of otch are the setting of staggering, constitute the head and tail of screw thread respectively.
Above-mentioned screw thread is a single screw thread.
The beneficial effects of the utility model are: tapped hole described in the utility model, can save this procedure of artificial tapping by mould impact briquetting in batches, and improved the manufacturing efficiency of finished product greatly; And be not with burr by the tapped hole that die stamping forms, its Security is guaranteed, and has fundamentally eliminated to leak the defective of attacking in the artificial tapping process easily.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Among the figure: 1, sheet metal, 2, otch, 3, endoporus, 4, screw thread.
Embodiment
As shown in Figure 1, a kind of tapped hole described in the utility model comprises: endoporus 3, the edge of endoporus 3 are provided with an otch 2 that connects with endoporus 3, and the both sides of otch 2 are the setting of staggering, constitute the head and tail of screw thread 4 respectively; Described screw thread 4 is a single screw thread.
During practical application, determine tapped hole according to employed single-threaded screw, quantity and position according to required pore-forming on the sheet metal 1 makes stamping die and forming die respectively then, be respectively arranged with the drift that endoporus 3 and otch 2 with described tapped hole adapt on the relevant position of stamping die, forming die is the screw thread 4 corresponding concavo-convex moulds of a pair of and described tapped hole; Like this, just can go out endoporus 3 and otch 2 by the relevant position of stamping die on sheet metal 1 on the stamping press, then, on the relevant position of the sheet metal 1 of going out endoporus 3 and otch 2 on the stamping press by forming die, stamp out screw thread 4 again, thereby saved this procedure of artificial tapping, improved the manufacturing efficiency of finished product greatly; And be not with burr by the tapped hole that die stamping forms, its Security is guaranteed, and has fundamentally eliminated to leak the defective of attacking in the artificial tapping process easily.
Claims (2)
1. tapped hole, comprising: endoporus [3] is characterized in that: the edge of described endoporus [3] is provided with an otch [2] that connects with endoporus [3], and the both sides of otch [2] are the setting of staggering, constitute the head and tail of screw thread [4] respectively.
