Description

In the groove 12 of the slide inserted hinged shoe 19 with the axle 20 pressed into it. Rollers 21 are put on the ends of the axle. A tooth 22 is attached to the rear end of the shoe, made in the form of a round pin inserted into the shoe hole and fixed in it by welding. The tooth 22 enters the hole 14 of the bottom of the ram. At the rear end of the shoe 19, a rotatable eccentric axis 24 is inserted into the hole 23, on the eccentric ends 25 of which rollers 26 are freely put on and the handle 27 with clamps 28 is fixed. The shoe is provided with holes 29 and 30 for clamps 28 and thrust rods 31 and 32 to limit the extreme positions of the knob 27.

At the upper end of the shoe 19 is articulated, using a finger 33, a flat self-aligning stop 34 is fixed. Its plane is provided with a soft (for example copper) metal interchangeable pad 35. The height of the stop 34 is such that with small diameters of the products it rests on them with the lower part, and for large diameters - the upper part. The width of this stop is made as large as possible and is almost equal to the width of the C-shaped bed 1. The bed enters between the rollers 36 mounted on the shafts 37, resting c .q on the pillars 38. Connecting parts 39 are placed on the rollers 36. A stop 40 is installed at the end of the roller stand, movable in height along the rack 41. The pitch of the holes 14 is less than or equal to the stroke of the hydraulic cylinder 6. All hydraulic cylinders are driven from the pump station 42. When the hydraulic cylinder 6 is displaced longitudinally, the bed is held by the stop 43, which engages with the rail 44, replennoy between the rails 9.

In the initial position, the frame is removed from the zone between the rollers 36 and is in the extreme right position. A section 39 of the part 39 is installed on the rollers in the immediate vicinity of the stop 40. Then the bottom is installed between the section of the part 39 and the stop 40. The shoe 19 is installed at a distance from the axes of the cylinders 4 and 5, approximately equal to the length of the docked section. For this purpose, the latches 28 are pulled out of the holes 29 and the handle 27 and turned (Fig. 3 and 7) counterclockwise against the stop into the rod 32 and fixed, the clamp 28 is inserted into the opening 30. In this way, the eccentric axis 24 rotates with the handle 27, and the rollers 26 abut against the upper surfaces of the crawl 11. As a result, the rear end of the shoe 19 rises, turning the shoe counterclockwise around the axis 20, and the tooth 22 disengages from the hole 14. Then the shoe 19 is moved to the desired position. At the same time, the shoe moves easily due to the rolling of the rollers 21 in the guide 12 and the rollers 26 along the upper planes of the slider 11. After the shoe 19 is installed into the desired

the position of the handle 27 in the order opposite to the one above, is turned clockwise. The shoe also rotates clockwise, and the tooth 22 enters the nearest hole 14, the rear part of the shoe abuts the bottom 13 of the slider slot, and a gap is formed between the rollers 26 and the slider preventing the transfer of workloads to the rollers 26. Turning on the drive

8, a bed is inserted between the rollers 36 until the axes of the cylinders 4 and 5 coincide with the junction of the sections. Put the stop 43 into engagement with the rail 44, producing fixation of the frame relative to the joint. Cylinder 6 is turned on. Stem 18, moving the frame through finger 17 and erector 16, moves along guides 10 a slider 11 with a shoe 19 and an emphasis 34, which, pressing the end of the section, presses it to the bottom or to the previous section, select the clearance in the junction.

At the same time, the soft overlay, 35 prevents damage to the end of the docked section, and the stop 34, by turning around the finger 33, is self-aligning along the end of the section, ensuring the contact of the overlay

35 with a section on the maximum surface.

Since the pitch of the holes 14 is less than the stroke of the cylinder 6, it is practically provided that the sections of any length are docked. When the cylinders 4 and 5 are turned on, their rods converge, aligning the edges of the sections, after which the joint is tacked. To continue the further assembly, it is necessary to turn the section through a certain angle, for which it is necessary to release

them from clamping cylinder 4-6. After the sections rotate, dock and tack again, and so along the entire perimeter of the joint.

To attach the next section, the frame is retracted to the right, having previously uncoupled the stop 43 with the rail 44. The rollers 36 install a new section of the part 39. If its length differs from the previous one, then the shoe 19 with the stop 34 is set to the size corresponding to the first section, and DOCKING in the described sequence.
