Abstract
The invention relates to a thin steel plate thread fixing mechanism and a manufacturing method thereof and belongs to the technical field of machinery manufacturing processes. The thin steel plate thread fixing mechanism is characterized in that a threaded pipe is fixed on a thin steel plate through convex steps and flange edges on two sides of the threaded pipe. The manufacturing method comprises the steps of blanking, forming and assembly and the like. The assembly process comprises the steps of installation, opening expansion, flattening and tapping. The thin steel plate thread fixing mechanism has the advantages that parts are attractive in appearance, a manufacturing process is good, the quality is guaranteed easily and connecting strength is high.
Description
Technical field
The present invention and a kind of sheet metal screw thread fixed mechanism and manufacture method thereof, belong to manufacturing technology technical field.
Background technique
As everyone knows, the boss hole that sheet metal screw thread fixed mechanism generally comprises sheet metal and is connected as a single entity with sheet metal, in described boss hole endoporus, attack screw thread, its manufacture method is the manufacture method that adopts the flanging process in cold punching technology, this sheet metal screw thread fixed mechanism, although its manufacturing process has advantage simply and easily, but because the thickness of steel plate is generally thinner, made boss hole wall is also thinner, in addition the height of boss hole boss is limited, cause linking intensity and the rigidity of screw thread all lower, thereby, be not suitable for need to having the place of higher linking intensity and rigidity to use at some, so there is the place of higher linking intensity and rigidity at ask for something, generally to make through hole in sheet metal relevant position, and directly over through hole the nut of welding standard on the sheet metal of position, thereby make sheet metal screw thread fixed mechanism, although this sheet metal screw thread fixed mechanism has solved the strength and stiffness problem connecting, but, owing to adopting the technique of welding in the process of manufacturing, there is the defect that manufacturing efficiency is lower, especially because steel plate is generally thinner, not only easily cause the defect of steel plate deformed, also easily cause burning steel plate, cause scrapping of workpiece, in addition, obviously also there is the poor defect of workpiece appearance quality.
Summary of the invention
The object of the invention is to: for existing sheet metal screw thread fixed mechanism and the existing above-mentioned defect of manufacture method thereof, the invention provides a kind of novel sheet metal screw thread fixed mechanism and manufacture method thereof.
Sheet metal screw thread fixed mechanism described in this technological method, it comprises: sheet metal and threaded pipe, described threaded pipe runs through steel-sheet two sides, in the center hole of described threaded pipe, is shaped with screw thread, and described threaded pipe is fixed on sheet metal by boss rank and the flange edge of both sides.
Manufacture method described in the present invention comprises:
(1) technology for blanking: described blanking comprises the blanking of sheet metal blanking and threaded pipe blank;
(2) moulding process: described moulding process comprises ironing steel plate bottom outlet and threaded pipe moulding process, described threaded pipe moulding process comprises: necking down technique;
(3) assembly technology: comprise installation, enlarging, pressing, tapping: described installation refers to the manufacturing process that the cylindrical of the necking down of the threaded pipe blank of necking down is installed into sheet metal bottom outlet; Described reaming refers to that the internal orifice end flaring die of the necking down end of mounted threaded pipe blank makes down the process of female cone; Described pressing is to adopt flattening die the threaded pipe oral area compacting of enlarging to be formed to the process of flange edge; Described tapping is the process of threaded screw thread in threaded pipe blanking inner hole.
beneficial effect: together with being anchored by cold punching technology with sheet metal due to threaded pipe, threaded pipe can be made higher strength and stiffness in addition, has accessory appearance attractive in appearance, and manufacturing process is better, the advantage that quality easily ensures and linking intensity is higher.
