Abstract
The invention discloses an angle opening die for angle steel. The angle opening die comprises a female die and a male die which are separated from each other, a V-type groove is formed in the upper end of the female die, and the opening included angle of the V-type groove is larger than 90 degrees. An outward-protruding pressing strip is arranged at the lower end of the male die, and the lower portion or all of a horizontally-arranged cylinder is arranged on the protruding portion of the pressing strip. The angle steel used for angle opening can be contained in the V-type groove, and the protruding portion of the pressing strip can be contained between two wings of the angle steel and is in contact with the inner side faces of the two wings. When the angle opening die is used for angle opening, dovetail-type elastic deformation is avoided after angle opening of the angle steel by changing the stress point in the process of angle opening of the angle steel, and the angle opening quality of the angle steel is guaranteed.
Description
Technical field
The invention belongs to steel construction processing technique field, be specifically related to a kind of angle opening die for angle steels.
Background technology
Be similar to Chinese patent application CN201020203635.9, CN201310370648.3 and CN201110385258.4, traditional steel angle opening method is to use the punch of angle of designing requirement and corresponding die, under the acting in conjunction of pressure, make angle steel open up into the angle of Design of Dies.But because the active force of such opening mold is on the limit of angle steel; when punch will separate with member; often there will be member and punch to be difficult to separated situation; and after separation; easily cause the strain that occurs dove-tail form after steel angle opening; make angle steel limit become curved surface, affect the presentation quality of member.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of angle opening die for angle steels, and the strain of dove-tail form has been avoided occurring after steel angle opening in stressed position during angle of release when changing steel angle opening, has guaranteed the angle of release quality of angle steel.
For solving the problems of the technologies described above, the present invention will be by the following technical solutions:
Angle opening die for angle steels, comprises the die and the punch that are separated from each other; Described die upper end is provided with V-type groove, and the opening angle of V-type groove is greater than 90 °; The lower end of described punch is provided with the press strip of evagination, the bottom that the projection of press strip is the flat sleeping cylinder arranging or whole; In V-type groove, can hold the angle steel for angle of release, the projection of press strip can be placed between the both wings of this angle steel and contact with the medial surface of both wings.
Further, described press strip is cylindrical, and the lower end of punch arranges groove, and the top of press strip is fixed in groove, and expose outside groove bottom, so that press strip can firmly be fixed in the lower end of punch.Generally, can select suitable round steel to use as press strip, the round steel that diameter is 50～100mm is the most conventional.
Preferably, the opening angle size of described V-type groove is preferably the angle after steel angle opening; Wherein, the angle of release angle of 120～150 ° is the most conventional.
Preferably, the projection of described press strip is placed in for after between the both wings of the angle steel of angle of release, answers line to be contacted with the position of centre of gravity of angle steel both wings.Conventional opening mold to steel angle opening after, its distortion is generally all the region occurring on angle steel both wings center of gravity, now, because press strip line is contacted with the center of gravity of angle steel both wings, can make that angle steel is stressed to be uniformly distributed, and guaranteed near angle of release process stress point region on the lower side position of centre of gravity and position of centre of gravity always, more can effectively avoid the distortion of angle steel.
In addition, described die bottom also can be provided with backing plate, the suffered pressure of die when cushioning angle of release.
The invention has the beneficial effects as follows:
The greatest improvement point of this angle opening die for angle steels is, in punch lower end, cylinder press strip is set, the stress point of press strip when steel angle opening acts on the medial surface of angle steel both wings, rather than the edge of angle steel, and the process punch that has guaranteed angle of release contacts with angle steel inside cord all the time, avoid occurring after steel angle opening not easily separated between the strain of dove-tail form and punch and angle steel, guaranteed the angle of release quality of angle steel.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of the present invention.
Number in the figure: 1, punch; 2, press strip; 3, angle steel; 4, die; 5, backing plate.
The specific embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, the angle opening die for angle steels of the present embodiment comprises die 4 and the punch 1 being separated from each other; Die 4 upper ends are provided with V-type groove, and the opening angle of V-type groove should be greater than 90 °, and are preferably the angular dimension after angle steel 3 angle of releases; The lower end of punch 1 is provided with the press strip 2 of evagination, and the projection of press strip 2 is the bottom of the flat sleeping cylinder arranging; In V-type groove, can hold the angle steel 3 for angle of release, the projection of press strip 2 can be placed between the both wings of this angle steel 3 and contact with the medial surface of both wings.
Wherein, described press strip 2 is columniform round steel, and the lower end of punch 1 arranges groove, and the top of press strip 2 is fixed in groove, and expose outside groove bottom.Press strip 2 should be selected the round steel of suitable diameter, so that the projection of press strip 2 is placed in for after between the both wings of the angle steel 3 of angle of release, line is contacted with the position of centre of gravity of angle steel 2 both wings.In the present embodiment, the diameter of press strip 2 is preferably 50～100mm, and the opening angle of V-type groove is preferably 120～150 °.
In addition, described die 4 bottoms are also provided with backing plate 5.
During use, first according to the angle of release of angle steel 3, require to select suitable die 4, press strip 2 and punch 1, then die 4 is installed on backing plate 5, press strip 2 is fixed on die 4, according to the thickness of angle steel 3, select suitable press device, after the V-type groove that is placed in die 4 until angle steel 3, with press device, by press strip 2, strut angle steel 3 to suitable angle.
