Abstract

The invention relates to the processing of metals by pressure, in particular, to jress for straightening sheets and allows for the correction of the curvature of sheet metal (SLM), on a press (P) with a higher productivity than on known structures P, ensuring at the same time more reliable operation of equipment . II is provided with two support beams, interacting with shock absorbers fixed on the table and transport rollers retracting into the table cuts. In the process of straightening, NM is fed under the movable yoke P, which, moving down, first lowers the support beams together with the rollers below the working surface of the table, as well. then presses LM to this surface, carried out its editing. 1 hp f-ly, b 5 ill.

The invention relates to the processing of metals by pressure, namely to equipment for straightening sheet material.
The purpose of the invention is to improve the productivity of the process of editing and reliability of the press.
Fig, 1 shows the proposed press, front view; in Fig.2 a section aa in Fig.1; on fig.Z - section bb in figure 2; 4 shows the node I in FIG. 3 in the straightening position; Fig, 5 - the same, after editing,
The press for straightening sheet material contains upper 1 and lower 2 traverses connected by columns 3, movable traverse 4 and working hydraulic cylinders 5 placed in the upper traverse.
The table is fixed on the lower traverse.
6 with driven rollers 7. In the side walls of the table, slots 8 are made and limiters 9 are installed. In the slots of the table there are supports 10 of rollers 7 in which grooves are made and which rest on limiters 9 in the lower position of the rollers. In the upper position of the rollers of the support 10 lie on the support beams 11 located on both sides of the table along the feed axis.
Each of the beams is freely mounted on two press columns and can be moved along them. The beams 11 rest on the damper rods 12 mounted on the ng-traverse. The side restrictive rollers 13 are rigidly fixed on the beams 11 in the upper part. The beams are equipped with guide sleeves 14. In the initial position, the support beams 11 with the help of shock absorbers 12 hold the drive rollers
7 above the surface of the table 6. The lateral limiting rollers 13 are also above the surface of the table on either side of it, but slightly lower than the sleeves 14.
Press for straightening sheet material works as follows
 The sheet to be edited is driven by the drive rollers 7 into the press working space, and the side limiting rollers 13 prevent the sheet from moving, increasing the reliability and accuracy of setting the sheet to the editing position. Due to the absence of any additional devices in the press working space and devices that prevent movement of the sheet, its feed to the straightening position is greatly facilitated and carried out without the use of manual labor.
The mobile yoke 4 under the action of the hydraulic cylinders 5 is lowered and, acting on the direction of the sleeve 14 of the support beams 11, lowers them together with the side rollers 13, overcoming
Amortized resistance 12. Along with beams, they are lowered freely; drive rollers 7, lying on them, with an extra sheet lying on them. The supports of the last 10, moving to
The 5 slots of the table 6 meet the stops 9 and are kept by them from further lowering. In this case, the prefab rollers are below the surface of the table at a given distance from it, and the sheet to be straightened on the table, the position of the sheet being strictly fixed by the side rollers.
In this position, the sheet is edited, which is acted upon by the force of the movable cross-member, which presses it against the surface of the table. Once the sheet has been edited, the traverse continues to lower. Under its action, beams 11 continue to descend.
0 Thus, in the process of editing
drive rollers lowered below the table surface do not affect the bottom surface of the sheet, which contributes to improved quality
5 edits. In addition, the design of the rollers, which is subject to a small load, depends only on the weight of the sheet, which is simplified. At the end of the traverse straightening, 4 return cylinders (not shown) are raised. The shock absorbers 12, acting on the support beams, press their guide bushes 14 to the surface of the cross member and lift the beams, which, when moving
5, meet the supports of 10 drive rollers and lift them together with the etched sheet above the table surface. The drive of the rollers (not shown) is turned on and the sheet is withdrawn from the working space of the press, and the traverse is raised to the initial position, coming out of contact with the guide sleeves 14.
The use of the proposed product (compared with the prototype) increases productivity by 15-20% by reducing the time lost when the sheets are set to
editing and exclusion of manual labor in the implementation of the operation.
