SU867474A1 - Die for cutting out angles in angular rolled stock flanges - Google Patents

Description

one

The invention relates to the processing of meta. Plastics by pressure and can be used in mechanical engineering for the processing of angular rolled metal.

Known stamp for cutting corners in the shelves of angular rolling, containing a fixed plate, a matrix mounted on it with two angled to one another the cutting edges, a movable plate placed on the matrix rotatably relative to it and a bearing ruler with stops, and a punch 1.

However, the rotation of the plate with the linear -. This is not enough to tune the corner, additional adjustment of the stops using templates or reference details is needed, which complicates the changeover of the stamp.

The purpose of the invention is to simplify the changeover of the stamp when cutting corners in the shelves.

The goal is achieved by the fact that in a die for cutting corners in the shelves of the angular rolled metal containing a fixed plate, a matrix mounted on it with two cutting edges at an angle to one another,

placed on the matrix with the possibility of turning relative to it and the carrier line with stops, and the punch, the axis of rotation of the movable plate is aligned with the apex of the angle formed by the cutting edges of the matrix.

1 shows a stamp, a general view (top view); figure 2 - razoto cut aa in figure 1; on fig.Z - section BB in figure 1; figure 4 is a section bb In figure 1; in fig. 5-7 - sketches of the obtained parts.

The stamp consists of a fixed

15 of the plate 1, on which the holder 2 is fixed with the matrix 3 and the counter-pressing 4. The matrix 3 and the punch 5 have a cutting contour in the form of a right angle. To the holder 2 with screws 6, the sector 7 is fixedly fixed 20, the center of which coincides with the top of the cutting angle of the matrix 3. A scale 8 is rigidly connected to sector 7, graduated with - symmetrically from O to

25

1 With the yoke 2 and the sector 7, the movable plate 9 interacts with the symmetry on the axis of symmetry, having the possibility of rotating with the aid of the handle 10 along a cylindrical surface

30 of sector 7 with the center of rotation coinciding with the tip of the straight yivin cutting; its contour is matched 3. The handle 10 is attached to the MOBILE plate 9 with a screw 11. In the handle 10 10, there is a jolly spring 12, the clamp 9 plate to sector 7.

In sector 7 there is a groove for the passage of the handle 10 when the plate 9 is rotated. On the handle 10 there is a nut 13, in turn: 1: 1, by which the pressing action of the spring 12 can be removed to facilitate the rotation of the PMITEL 9 In the T-slot of the yoke 2 bolts 14, which, when adjusted, secure the plate 9 to the holder 2 nut 15, plate 16 with bolts 16 and nuts 17 attached to the bar 18, having the ability to move along the guide groove 19 of plate 9.

On the strip 18 with the help of the bolt 20, the nut 21 and the clamp 22 of the assembly line 23, it is possible to move relative to the strip 18 during adjustment. On the ruler 23 and on both sides there is a scale of millimeter divisions, and zero risks are in one place. with abutment surfaces of the stops 24, made on the ruler 23. The clamp 22 is precisely oriented along the groove of the section 18 and has a risk that coincides with the axis of the punch, relative to which the reference line 23, reads,

With the strap 1c, xiJOHiMTefiHtJ 25 are rigidly connected, on which the pressure plates 27 are movably mounted with screws 26. The pressure plates 27 press the workpiece to the strap 18 by means of springs 28.

On the fixed plate 1 nuts 29 and bolts 30 fasteners 31, which prevent the vertical movement of the workpiece in the process of stamping.

The symmetrical design of the 1-key 8 and the line-Hzhi-23 is necessary for two-sided processing of workpieces.

The rjj-amp tuning is performed as follows.

To trim the corners of the various frames, the distance ci from the bar 18 to the top of the cutting contour of the die is set by moving the bar 18 through the groove 19 of the movable plate 9. After adjusting the size od, the strip 18 is clamped on the g-; matte fx.iTriMH 16 and (1and 1 7.

When setting up: 1T. on about; -h angle from 0 to 35 ((uir.S) ruler 23 is set; 1 is zeroed at the risk of pressure 22. When cutting the left side of the corner, it uses (;: the right part of the line 23, and when cutting the right, left Part 23. After installing the ruler 23, the movable plate 9 is rotated relative to the matripe 3 by the handle 10 to the desired angle, measured on a scale; 1e 8. When cutting the left side of the corner of the plate 9, it turns to the right side of the scale 8, and when cutting the right side, to the left After

5 installation plate 9 it is fixed on the holder 2, clamping the nut 15.

For trimming in the straight angle shelf (Fig. 6), the ruler 23 shifts relative to the risks of the clamp 22 by the required amount, measured on the scale of the ruler 23, the movable plate 9 is rotated relative to the matrix by an angle of 45.

5 For trimming the corner at 1ibka in the corner steel shelf (Fig. 7), the line 23 is displaced by the required amount, and the mounting plate 9 is set to 0. The combination of the rotation axis is mobile

Q plate 9 with the top of the angle of the cutting contour of the matrix, simplifies setup and reduces the time to set up the stamp.
