EQUIPMENT FOR CALIBRATING YON PIECES WITH CHANGING PROFILES

The present invention relates to equipment for pressure forming of metals, more precisely on devices for straightening piece products with variable profiles Cross-sectional.

The present invention can be most effective for calibration. can be used by latch needles.

At present devices for straightening latch needles are known which have a table for storage a needle package on the same, which is held on the table at the moment of the straightening process by a hold-down device attached above the mentioned table,

as well as calibration rolls mounted on levers, which form two parallel rows, in the gap between which the section of the needle sheet free of the hold-down device (see for example above copyright of the USSR Ur. 182101 according to class 7e »6) finds its place. In this device, the table is progressively moved together with the needle package by tie rods connected to the drive shaft mounted cams in the direction perpendicular to the direction of travel of the package along the table, and the rollers are mounted on levers that are below Under the action of cams fixed in the grooves of a rotatable disc mounted on the same shaft.

The straightening process takes place on the known device intermittently due to the progressive movement of the Table. The number of straightening rollers in this device is limited by being in the grooves of the rotatable washer only a limited number of cams can be attached to control the levers with the straightening rollers. As a result of the limited The number of straightening rolls is the number of needle bends low to one side or the other.

The working cycle of the known device closes the time for the advance of the needle package along the table, the intermittent transverse movement of the table and the Needle bends to one side or the other with each standstill of the table, which is not a sufficiently high

309844 / CU54

Can achieve work performance.

In addition, the limited number of calibration rolls reduces and thus the limited number of wraps the quality of the needle straightening. Furthermore, in the known Establish the Naaeln only in the section of the JJadelfuß (from äaaelvorsprung) to be directed to the end of the same, but the section behind the loading foot (rear end the needle) is impossible to straighten because this section is on the table under the hold-down - this also affects the straightening quality, because to ensure the high quality straightening on the whole The length of the needle is necessary.

In addition, the constant reciprocating movement of the table in the transverse direction creates obstacles when operating the device.

The aim of the present invention is to eliminate

4> the disadvantages mentioned above.

The invention is based on the object of creating an execution for straightening piece products, which a high quality straightening along the whole length of the product nowie high work efficiency and convenient operation thanks to an increase in the number of folds of the product in different places of the same after the one or the other side when moving the JSadel package guaranteed along the immovable table.

variable cross-section, which contains a table for the ^{v of} a needle packet on the same, which is held on the table at the moment of the straightening process by means of a movable hold-down device, which is mounted above the mentioned table, as well as straightening rollers mounted on rotatable levers, which form two parallel rows , in the gap between which the section of the package of products free from the hold-down device finds its place, according to the invention, step-shaped continuous cutouts are made on the side surfaces of the table and hold-down device, in which the mentioned straightening rollers are housed, while the steps of the cut-outs are arranged one opposite the other are in such a way that they form a stepped line of the successive bending of the package of products as they pass it between the rows of straightening rollers. Thanks to the step-shaped cutouts, the number of bends of the products to one or the other side increases at different points, which increases the work efficiency of the device and improves the quality of the straightening. In addition, thanks to the stepped cutouts, the package of products moves only along a table, which is immobile, which eliminates the time for the transverse feed of the package of products together with the table and thus increases the work efficiency. ■ For this purpose, the product

(EIg.1) to the γ of a .Nadel package 2 on the same, a hold-down device 3, which is mounted above the table 1 and holds the Hauel package 2 at the moment of the ßichtvorgangs, Hichtrolle 4 and a device 5 for moving the

309844/0454

Needle package 2 over the table 1 after the completion of a straightening cycle. On the side surfaces of the table 1 and the hold-down device 5, step-shaped continuous cutouts 7 and 7 (FIGS. 3 and 4) are made, in which the mentioned straightening rollers 4 are accommodated. The steps of these cutouts are arranged one opposite the other in such a way that they form a stepped line of the successive bending of the needle package when it passes between the rows of straightening rollers. The hold-down ? be, sitat a work surface 8 (i'ig.2), the profile of which corresponds to the profile of the needles to be processed and which has a continuous longitudinal groove 9 for the passage of the foot 10 of the needles.

In the table 1 there is a cutout 11 to ensure the straightening of the section behind the foot 10. The steps, in the table and in the hold-down device are designed in such a way that that when you press down almost the entire section of the needle body from the needle butt to the end remains free, then this open section when moving the needle package over the table to the right (according to the drawing) slowly becomes shorter and shorter, then only the end of the needle remains open and finally only the section behind the needle butt on the other 3 side is free, while the rest of the needle part is pressed against the table 1 by the hold-down device 3. The table 1 is mounted on cantilever arms 12 on a Plate 13 are attached.

The hold-down device 5 is attached to a lever 14, which is rotatable about the axis 15 by a cam 16, which sits on a shaft 17. The axis 15 is located in a stand 18. The shaft 17 receives its rotary movement from an electric motor 19 (3? ig.1) via a belt drive 20, a pair of worm gears 21, 22 and a chain drive 23 and 24.

The Rient rolls 4 are arranged on Liebeln 25-54- of which the levers 25-29 are housed above the needle package 2 and are attached to a ball 55. This wave is arranged in bearings 56 and is on a her attached lever 57 of one. Bocken 58 »the one on the λeile 17 sits, set in rotation. The levers are 5 ° -5 ^ arranged under the needle package and oefeatigt on the shaft 59, which is arranged in bearings 40. The V / elle 59 receives its rotary movement via a mounted on it Lever 41 from a cam 42 which sits on shaft 17. The bearings 56 and 40 are housed in the stand 10.

The levers 14, 57 and 41 each wexuen to the squat 16, 58 and 42 pressed on by springs (not shown in the drawing).

The width of each roller 4 is slightly less than half the step width of the table 1 and the hold-down device 5) and the levers 25-54 are arranged such that the liollen of a jeuen raares (the upper and the lower) do not lie one opposite the other.

This arrangement allows all upper and lower Roll to participate in the work at the same time, so that the corresponding sections of the .Nadel package 2 up and be bent downwards, whereby a high work performance is ensured.

The package 2 is pressed against the hold-down device 3 by a bar 4j5 with the aid of a weight 44 and a thread 45, which is looped over rollers 46, 47 and 48.

Hit the roller 48 is connected to a ratchet wheel 49 of the device for moving the needle package over the table. This device also includes a filinke 50 (FIG. $) Which is fastened on an axle 51 which is arranged on a lever 52. This lever interacts with cams 55 ^and 54 mounted on the shaft 17.

with the hold-down device 3 attached to it, which presses the needle package 2 against the table 1 with its surface 8. Thereafter, the cams 38 and 42 take over the levers 25-54 by means of the rollers 4 bending of individual sections of the needle package up and down with respect to the line aes meeting of hold-down 3 and table 1 before. Here, the roller 4, which is attached to the lever 25 (FIG. 6), bends the section of the needle package below it near the line where the first stages of the table and hold-down device meet. The cover 4, which is arranged on the lever JO (3? Ig.7), bends the section of the needle package located above it in the vicinity of the same line of the meeting of the first stages upwards. As a result of the bends vns / A up and down, the needles are directed in the section adjacent to the line of meeting of the first stages.

The rollers 4, which are attached to the levers 26 and *> 1 (KLg.8 and 9), bend their sections of a Naael packet downwards and upwards in the vicinity of the meeting of the second stages of table and hold-down device , the previously directed needle sections on the line where the first stages meet are now pressed against the table. The rollers 4, which are attached to the levers 27 «τ><1 CFig.10 and 12), bend downwards, the rollers 4 in turn, which are attached to the levers 32 and 33 (E'ig.11 and 13) , up their sections of the

309844/0454

Needle package near the meeting point of the subsequent Step up, and are they ready in any case? directed needle sections pressed against the table.

The rollers 4, which are attached to the levers 29 and 34 (Fig. 14 and 15), each bend downwards and downwards up their sections of the needle package in the zone behind the nail foot, and here the pins are all over The section from the needle butt Ms to the end of the needle is pressed because this section is already straightened. Everyone on the levers attached rollers 4 'take step-like on one

the other bend over the entire length of the needle.

Since the feed rate during a work cycle of the device is smaller than the width of each roll, each needle necessarily bends up and down at the meeting lines of each step pair of table and hold-down device. Here it is assumed that vienxL individual needles twice under the influence of one and the other? the same roll, ie if sift are bent up or down twice at one and the same point (v / o one and the same pair of steps meet), this cannot affect the quality of the straightening.

After the completion of the rectification process, when the above Straightening rollers 4 from <xen levers 25-29 and the hold-down device 3 lifted up by the lever 14 and the lower rollers are lowered down by the levers 30-34, whereby the needle package 2 is released, the pre-

Here, the lever 52, in which the axis 51 is arranged with the pawl 50 attached to it, reaches the section of the bracket 55 with a smaller diameter, whereby it moves together with the The pawl 5 ° i & relative to the axis of the ratchet wheel 49 rotates. Here, the pawl 50, while remaining in engagement with the teeth of the ratchet wheel 49, rotates the same counterclockwise on the axis by a certain angle which corresponds to the size of the difference in diameter of the jib 53.

The thread 45 with the weight 44, which over the with the Ratchet 49 connected roller 48 is looped, lowers, which is why the bar 43 the iJadei package 2 over the table 1 to the right by exactly the required distance, which is the size of the difference in diameter of the cam is determined as well as the length of the lever 52 and the diameter of the roller 48.

After completion of the advance of the needle package 2 over the table Λ to the right, the hold-down device 3 presses the package against the table, and the straightening process begins anew. At this time, when the weight 44 does not allow spontaneous advancement of the iiauel packet, the squat 54 rotates while it presses the lever 52, this together with the pawl pQ, which disengages it from the teeth of the ratchet wheel 49. Then the cam 53, iii it presses on the lever 52, brings this lever together
