Недостатками мащины вл ютс больщие размеры относительно длин обрабатываемых изделий заготовок, а также возможность резкоге обрыва изделий в процессе правки, что снижает безопасность работы на ней.The disadvantages of the maschina are the large sizes relative to the lengths of the workpieces being processed, as well as the possibility of cutting off the products during the dressing process, which reduces the safety of work on it.

Цель изобретени - снижение габаритной длины, улучшение условий эксплуатации и повышение безопасности работы при резком обрыве издели .The purpose of the invention is to reduce the overall length, improve operating conditions and improve safety when a sharp break in the product.

Указанна цель достигаетс тем, что в правильно-раст жной машине, содержащей установленные на катках станины и несущие зажимные головки т нущую приводную от гидроцилиндра каретку и неподвижнуюThis goal is achieved by the fact that in a straightening machine containing beds installed on rollers and bearing clamping heads, the carriage is driven by a carriage and fixed

Claims

mi 7, have vertically oriented work surfaces. Under the carriage 3, the hydraulic cylinder 8 is rigidly fixed on the frame, the rod of which is pivotally attached to the bracket of the carriage 3. The stationary carriage 4 is pivotally attached by means of the screw-nut mechanism 9 to the elastic-fixing carriage 10, which can be installed in several 1x position along the length of the frame 1, with the installation pitch not exceeding the stroke of the screw between its extreme positions. The carriage 10 is fixed on the bed by means of a pin II, which is inserted into an inclined groove a serving as a wedge and located in the carriage 10, and at the same time into the through holes of the bed 1. The vertical composition of the carriage 10 arises Stretching force, which presses the carriage 10 downwards, overcoming the spring resistance of the elastic bend of the bracket 12, the support rollers of which perceive the weight of the carriage 10. The movement of the carriage 10 downwards stops when it touches the arms ins I. After the stretching force of the elastic arm 12, carriage 10 returns to its original position. The proposed device of the spring-wedge mechanism for fixing the carriage 10 provides some elastic compliance of the stationary carriage 4 at the time of stretching, which reduces the energy emitted by the product 2 when it breaks and, in addition, signals the operator about the end of the curvature of the brains of the product and the beginning of the dressing, increasing operator productivity. The vertical orientation of the working surfaces of the cams 6 is ensured by the horizontal arrangement of the head bodies 5, thus reducing the distance between the axes of the product 2 and the hydraulic cylinder 8, as well as reducing the support reactions in the roller bearings of the carriage 3 and increasing its service life. The introduction of a straightening machine saves production space, reduces the weight of the stretching machine, which is in direct relation with a decrease in its length. Claim 1. Straightening and stretching machine, comprising beds and supporting clamping heads on a carriage and a stationary carriage connected to the fixing carriage by means of a screw and a nut, so as to reduce the overall length and to improve the operating conditions, the hydraulic cylinder is located on the frame under the carrying carriage and pivotally connected to the rod, and the stationary carriage is connected to the screw of the fixing carriage pivotally, while the frame is made Suitable grooves, and rollers nuschey t and fixed carriages mounted therein.

2.Mashchina according to claim 1, characterized in that, in order to increase the safety of work in case of a sharp break in the product, the locking carriage is connected to the frame by a spring-wedge mechanism in the form of a fixing pin, which is inserted into the groove in the carriage and through holes in the frame. , an elastic bracket with support rollers, as well as carriage consoles supported on the bed surface during stretching.
