Abstract

The invention relates to the processing of metals by pressure, in particular to equipment for bending bar-type workpieces. The purpose of the invention is to increase productivity, reliability. The device comprises a bending unit and a feed mechanism. The bending unit is made in the form of two coaxially mounted discs with gripping grooves on the shaft. The processors use the rollers placed on the frame as a reference tool. Arched cams rigidly attached to them are mounted on the disks. The feeder contains sliders with stepped combs, pushers and rods, bearing rollers. Sliders by stepped combs are engaged with the pushers. Pushers pivotally connected with rods. Rods interact via rollers with disco cams. During the bending process, the bar bends against the rollers of the support tool in the bracket. 3 or

The invention optsit to the processing of metals by pressure, often to the equipment for bending bars in the form of rods.

The purpose of the invention is to pave in the performance of a flexible and reliable process.

Figure 1 shows the device without the feed mechanism blanks, top view; figure 2 - the feed mechanism blanks, side view; fig.Z - feed mechanism blanks, top view.

The device comprises a bed 1, a gear 2, a pulley 3, a coupling sleeve 4, a shaft 5 of square section. On the shaft there are two discs 6 with catch grooves 7 parallel to the axis of rotation of the discs 6. Furthermore, on the shaft 5 there are removable holders 8 spaced across the width of the square of the shaft, which are clamped by a nut 9. The supporting element is when () serving as bending rollers 10 placed on the strap 1I rigidly mounted on the frame, supports 12 for the shaft 3, as well as inclined brackets 13 on which the corners 14 and 15 are mounted to the frame. Lower guides 16 are attached to the corner 14, and yrq: i- 15 - guides 17. Sliders are mounted on the lower guides 16 18 with stepped combs 19 that engage with the pushers 20, hinged together} 1 M1 1; spring-loaded rods 21 placed in guide tubes 22. Each stem is equipped with a transfer roller 23 in contact with arcuate cams 24 mounted on disks 6 and providing smooth movement of thrust pulleys 20. ia corner 15 has a magazine 25 and cross-sectional 26 corners; on the latter, guides 27 are placed forming the cells for laying the blanks.

The device works as follows.

Eight rods of the blank 28 are placed in the magazine cells formed by the guides 27, which corresponds to the number of slots 7 on the discs 6. At the beginning of the cycle, the entire assembly rests on sliders 18, which prevent the rolls 28 from rolling. welded to discs 6, click on the rollers

23, with the result that the spring-loaded rods 21, in turn, press the pushers 20, which advance the sliders 18. At the same time, the first guide guides 27 are opened and the workpiece is slit along the guide 16 directly to the discs 6, which with their grooves 7 capture the workpiece 28, G of the groove of the slots 7 corresponds to the thickness of the billet. The bending is carried out on the rollers 10, after which the resulting bracket falls down, with this pushing of 20 seconds. using the springs 29, they return to their original position and engage with the next gear stage of the dies 19.

Upon completion of the cycle, the sliders 18 ascend 5a1 to the initial position and the cycle is repeated.

The spacing between the gripping discs 6 15 is regulated with the help of C1 cage holders 8.
