Detailed Description

Referring to fig. 3-4, the angle steel chamfering tool for the building comprises a lower die and an upper die, wherein the lower die consists of a lower die base 1, a lower tool rest 9, a lower tool 5, an angle scale 8, a directional angle steel slide block 6, a rear material blocking and positioning angle steel slide block 2 and a fixing bolt; the upper die consists of an upper knife rest 4 and an upper knife 3; the upper knife 3 is positioned below the upper knife rest 4 and is provided with a cutting edge with inclination; the rear material blocking and positioning angle steel slide block 2 and the lower tool rest 9 are fixedly connected to the lower die base 1; the directional angle steel slide block 6 is connected above the angle scale 8 to adjust the fixed position and the cutting angle of the angle steel part 7; the lower blade 5 comprises a double-sided edge; the angle scale 8 is formed by engraving an iron plate and comprises two concentric circular arc hole grooves; the directional angle steel slide block is connected above the angle scale through a fixing bolt; two long holes are milled on the rear material blocking and positioning angle steel sliding block 2 to adjust the distance between the sliding block and the cutting edge.

Wherein, the upper knife 3 should be made into a blade with a certain inclination, and the lower knife 5 can be made into a double-sided blade to prolong the service life. Aiming at the angle steel chamfer with small angle (large shearing length), the upper edge of the side retaining surface of the directional angle steel slide block 6 can be made into an outward and downward folded shape, and the vertical edge of the angle steel material piece is inserted to play a role in preventing the material piece from jumping during punching and shearing during working. And a long hole is milled on the rear material blocking and positioning angle steel slide block 2 so as to adjust the distance between the long hole and the cutting edge. The distance is determined according to the length of the bevel edge of the triangular lower scraps to be cut correspondingly to the height, the height of the bevel edge is slightly higher than the upper surface of the lower cutter 5, and the width of the angle scale 8 generally exceeds the width of the lower die base 1 so as to better support the scraps.

In addition, the manufacturing of the angle scale is critical, an iron plate can be adopted for carving, and the angle scale is fixed with the lower die holder and the lower cutter for use after being bent and drilled, and the heights of the upper end faces of the three are ensured to be consistent. The directional angle steel slide block can move in two concentric arc hole grooves of the angle scale, and can be screwed and fastened by screws after the angle is determined. The angle range can be designed to be relatively common-70 degrees, and if the working area is enough, the wide angle range can be enlarged. 1 degree to 5 degrees can be selected according to each graduation of conditions, the design should ensure that the intersection points of extension lines of all scale lines of the angle scale are concentric with the circle center of the arc groove and fall on the cutting edge line so as to ensure that the gravity center is not unbalanced loaded when the punch works and if the two sides of the angle steel material piece need chamfering, a directional slider can be respectively fixed on the left side and the right side of the central graduation (90 degrees), the left side and the right side are alternated, and meanwhile, the angle steel material piece is overturned for use, so that the chamfering of the whole workpiece can be completed.

The utility model discloses a working principle of angle steel chamfer frock for building: and (1) aligning the scales on the angle scale according to the required chamfering angle of the pattern before working. And (2) fixing the directional angle steel slide block 6 according to the angle. And (3) fixing the positioning angle steel slide block 2 (the fixed position is proper to prevent the angle steel from entering too much to cause the contact of the upper cutter and the vertical edge of the angle steel part, thereby damaging the cutter). And (4) punching and shearing. (5) Melt cutting the other side (double side or double end chamfering) until the chamfering of the material is completed.

When the punching and shearing force is calculated, the calculation is carried out according to the largest specification material piece with the smallest angle; the clearance between the upper cutter and the lower cutter is designed according to the maximum wall thickness of the angle steel; the scale sequence of the angle scale is consistent with the angle of the workpiece, the middle scale mark is generally 90 degrees, and other scales are reduced towards two sides in sequence as shown in the figure. When the workpiece angle is 30 degrees, the corresponding angle of the angle scale is also 30 degrees.

To sum up the embodiment just describes the preferred embodiment of the utility model, is not to the scope of the utility model is injectd, all is in the technical idea and technical means or technical scheme of the utility model within, to any modification, equivalent replacement and improvement etc. that the utility model made all fall into within the scope of protection of the utility model.
