Abstract
The invention provides a method of increasing tightening torque by utilizing an edgefold and turnup process so as to fix screws onto metal plates, and the method can save cost, reduce overall weight and improve appearance of the metal plates. The edgefold and turnup process on the metal plates comprises a step of forming a edgefold part (11) on the main body (12) of the metal plate; a step of downwards folding the edgefold part superposed on the main body so as to be inserted into one side of the screw device; and a step of together forming the turnup of the edgefold part (11) and the main body (12).
Description
Technical field
The present invention relates to a kind of by using that flanging and flange are processed to improve Tightening moment and with the method for screw fastening to the metallic plate.
Background technology
Be used for screw is fixed on the metallic plate to obtain the conventional method of enough Tightening moments, be included in hole flanging on the metal with the method on the bent limit that is provided for closely keeping screw.In this conventional method, in the situation of steel plate, the thickness of the metallic plate that uses is generally 0.6 millimeter or thicker (referring to Fig. 1).When used thickness less than 0.6 millimeter metal sheet (in the situation at steel plate) and when using conventional method, be difficult to obtain enough Tightening moments.Therefore, the use of metal sheet is subject to for the restriction that obtains the conventional method of Tightening moment when being fixed on screw on the metallic plate.
For use conventional method screw is fixed on thickness less than 0.6 millimeter metal sheet on the time improve Tightening moment, must additional sheet metal be inserted into (referring to Fig. 2) in this structure by spot welding.
Therefore, the shortcoming of prior art is: the enough Tightening moments when needing a plurality of steps to obtain to be fixed on screw on the metal sheet.
Summary of the invention
According to the present invention, provide a kind of metallic plate has been carried out the method that flanging and flange process to improve Tightening moment, wherein flanging is processed and is comprised the part of metallic plate is turned up to overlay on the main body of metallic plate (referring to Fig. 3).
Purpose of the present invention, feature and advantage comprise provides a kind of two step method, in order to strengthening the surface of metal sheet, thus the Tightening moment when improving screw and being fixed on the metallic plate.
By detailed description of the invention with reference to the accompanying drawings, will fully understand these and other purposes, features and advantages of the present invention.
Description of drawings
By following detailed description to preferred embodiment and best mode, claims and accompanying drawing, these and other purposes, features and advantages of the present invention will be apparent, wherein:
Fig. 1 is the conventional method to the metallic plate flange;
Fig. 2 spots weld conventional method on the metallic plate with the additional metal sheet;
Fig. 3 is the normal axomometric drawing that metallic plate is carried out flanging and flange processing;
Fig. 4 is the sectional view that metallic plate is carried out flanging and flange processing;
Fig. 5 carries out the method that flanging and flange process to improve Tightening moment to metallic plate.
The specific embodiment
Fig. 1 illustrates and utilizes screw (4) will have the metal parts A(1 of through hole) be fixed to have hole flanging another metal parts B(2 of (3)) on conventional method.Hole flanging has the bent limit (5) of tight maintenance screw.In the situation of steel plate, the thickness of part B (6) need to be greater than 0.6 millimeter, to guarantee enough Tightening moments.
Fig. 2 illustrates and will have the metal parts C(7 of through hole) be fixed to thickness less than another metal parts D(8 of 0.6 millimeter) on conventional method.In order to ensure enough moment, with additional metal sheet (9) spot welding (10) to metal parts D.
Fig. 3 illustrates and metallic plate is carried out flanging and flange processes in order to improve Tightening moment.The flanging section (11) of metallic plate is folding with on the main body (12) that overlays metallic plate.(13) form hole flanging in the fold domain.
Fig. 4 illustrates the sectional view through the zone of flanging and flange processing.
Fig. 5 illustrates through the zone of flanging and flange processing how to keep tightly screw.The metal parts E(14 that will have through hole by screw (17)) be fixed to the metal parts F(15 that processes through flanging and flange) on.Can improve the Tightening moment of screw through the zone of flanging and flange processing.
When carrying out the flanging processing on folding with the main body that overlays metallic plate by the part with metallic plate, flanging is processed metallic plate is gained in strength.Include but not limited to that by using anchor clamps and mould come the folding plate of stacked warp to finish flanging and process.Carrying out flange processes to make hole flanging at metallic plate, so that patch material remains adhered on the described metallic plate so that larger screw torque to be provided.
Two step process of flanging and flange are convenient to improve the Tightening moment when thickness is used for the main body wallboard less than 0.6 millimeter metallic plate (in the situation at steel plate).
Although preferred embodiment of the present invention is had been described in detail, yet it will be recognized by those skilled in the art be used to realizing various alternate design of the present invention defined by the following claims and embodiment.
Industrial applicibility
Used thickness is more economical less than the advantage of 0.6 millimeter metallic plate.Form the main element that includes but not limited to automobile, air-conditioning etc. by used thickness less than 0.6 millimeter metallic plate, the parts of this structure also can make structural entity lighten and improve the outward appearance of described structure.
Claims (1)
1. one kind is carried out the method that flanging and flange are processed at metallic plate, comprising:
Form the step of flanging section (11) from the main body (12) of metallic plate;
The described flanging section on the described main body of overlaying is folded to the step of a side of inserting screw device downwards;
Described flanging section (11) and described main body (12) are formed together the step of flange.
