Abstract
The present invention relates to metal sectional bar manufacture, particularly to a manufacturing technology of a metal frame sectional bar, which is characterized in that manufacturing the metal frame sectional bar is mainly completed by the following technologies: cutting board, punching die and holes, and using the special purpose mould to bend and shape each corresponding edge in sequence. The present invention has the advantages that the present invention is suitable for making the sectional bar with various specifications and has flexible and convenient manufacture. A common bender can complete the sectional bar manufacture.
Description
Technical field
The present invention relates to a kind of making of shape, relate in particular to a kind of manufacturing process of metal framework section bar.
Background technology
Current, the manufacturing process of metal framework section bar mostly adopts tens meters large-scale knurling machines that metal material material is processed by a plurality of pressure rollers, a kind of shape moulding needs a lot of pressure rollers to finish, invest very big and produce dumb, processing specification and be restricted, especially plurality of specifications section bar processing is not suitable for.
Summary of the invention
The object of the invention aims to provide a kind of manufacturing process of metal framework section bar, and it is applicable to the making of plurality of specifications section bar, makes flexiblely, and common bender can be finished.
For realizing purpose of the present invention, the technical scheme that is adopted is: a kind of manufacturing process of metal framework section bar, it is characterized in that mainly comprising cut out plate, towards digital and analog hole, bending, moulding, concrete steps are as follows:
(1), cuts out plate: use conventional plate shearing machine that sheet material is cut into required width;
(2), towards digital and analog hole: use punch press to go out two row's digital and analog holes, and go out recess on a long limit at the good sheet material of sanction;
(3), bending, moulding: use common bender to adopt particular manufacturing craft, to corresponding each Edge Bend, its operation is successively:
A. roll over three quarter bends successively on the long limit of no recess,
It is B. curved at obtuse angle of jagged long edge break,
C. at the obtuse angle between the curved and quarter bend folding acute angle curved,
D. between obtuse angle and acute angle, roll over a quarter bend again,
E. be squeezed into the straight angle with acute angle is curved then, make its two sides be merged into faying surface, again faying surface is rolled over quarter bend;
F. after the curved branch in its obtuse angle being converted into right angle, acute angle and the straight angle successively, make its obtuse angle face be merged into faying surface, moulding.
Described obtuse angle is curved to be 100 degree-135 degree.
Described acute angle is curved to be 30 degree-60 degree.
The every round of described digital and analog hole put in order for square hole and circular hole alternately.
The invention has the beneficial effects as follows; It is applicable to the making of small dimension section bar, makes flexiblely, and simple bender can be finished.
Description of drawings
Fig. 1 is a bending technique flow chart of the present invention;
Fig. 2 is a bending flow chart of the present invention.
The specific embodiment
Further specify the specific embodiment of the invention below in conjunction with embodiment.
A kind of manufacturing process of metal framework section bar, mainly comprise cut out plate, towards digital and analog hole, bending, moulding,
Concrete steps are as follows:
1, cuts out plate: use conventional plate shearing machine that the sheet material of 1.4-1.5mm is cut into required width;
2, towards digital and analog hole: as shown in Figure 2, use punch press to go out two row's digital and analog holes, and go out recess on a long limit at the good sheet material of sanction; The every round of digital and analog hole put in order for square hole and circular hole alternately, its pitch-row is 12.5mm ± 0.1, centre-to-centre spacing is 25mm ± 0.2 between long limit recess of sheet material and the recess, recess is used in when miscellaneous part is installed and plays the role of positioning,
3, bending, moulding: use common bender to adopt particular manufacturing craft, to corresponding each Edge Bend, its operation is successively: as shown in Figure 1,
A. roll over three 90 degree curved (as 1 among Fig. 1,2,3) successively on the long limit of no recess, its first right angle is of a size of 18-20mm apart from the face width on the long limit of no recess, and second and third right angle is 21.5mm apart from adjacent right angle face width,
B. curved at one 100 degree of jagged long edge break-135 degree, (as 4 among Fig. 1), its bending width dimensions is 12-14mm,
C. folding 30 degree-60 degree are curved between obtuse angle and right angle, and (as 5 among Fig. 1), its bending width dimensions apart from the right angle is 35-37mm,
D. it is curved to roll over one 90 degree between obtuse angle and acute angle again, and (as among Fig. 1 6), be of a size of 42-45mm apart from face width between itself and the obtuse angle, be of a size of 58-60mm apart from face width between itself and the acute angle,
E. degree is curved is squeezed into the straight angle with 30 degree-60 then, and (as 7 among Fig. 1,8) makes its two sides be merged into faying surface, and be again that faying surface folding 90 degree are curved, as 9 among Fig. 9; It is of a size of 18-20mm,
F. with its 100 degree-135 degree curved divide be converted into 90 degree (as 10 among Fig. 1), 30 degree-60 degree curved (as 11 among Fig. 1) and 180 for three times and spend (as 12 among Fig. 1) after, make its obtuse angle face be merged into faying surface, its each face size is respectively 43-44mm, the section bar end face has the square hole of a 20 * 20mm after the moulding, its tolerance is ± 0.2mm in.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
