Description

Изобретение относится к основному технологическому оборудованию прокатного производства, а именно к станам для изготовления ступенчатых валов поперечно-клиновой прокаткой. 5The invention relates to the basic technological equipment of rolling production, namely to mills for the manufacture of stepped shafts transverse wedge rolling. 5

Цель изобретения - повьппение коэффициента использования рабочего времени стана путем сокращения времени настройки положения приемной призмы относительно проводок.The purpose of the invention is to increase the utilization rate of the working time of the mill by reducing the time to adjust the position of the receiving prism relative to the wiring.

На фиг.1 изображен стан для поперечно-клиновой прокатки, вид в планер на фиг.2 - разрез А-А на фиг. Г; на фиг.З - разрез Б-Б на фиг.2.In Fig.1 shows a mill for transverse wedge rolling, a view in the glider of Fig.2 - section aa in Fig. G; in Fig.Z - section bB in Fig.2.

Стан содержит станину 1, приводные 15 рабочие валки 2, узел центрирования заготовки, выполненный в виде размещенной в пазу станины рамки 3 с установленными в ней проводками 4 и приемную призму 5. 20The mill contains a frame 1, drive 15 work rolls 2, the centering unit of the workpiece, made in the form of a frame 3 placed in the groove of the frame bed with wiring 4 installed in it and a receiving prism 5. 20

Заготовка 6 подается на приемную призму 5 и фиксируется по оси прокатки 1-1. С приемной призмы заготовка подается в пространство между проводками 4, захватывается вращающимися валками 2 и прокатывается в профильное изделие. В конце прокатки заготовка освобождается из валков и удаляется из стана.The workpiece 6 is fed to the receiving prism 5 and is fixed along the axis of rolling 1-1. From the receiving prism, the workpiece is fed into the space between the wires 4, is captured by the rotating rolls 2 and rolled into the profile product. At the end of rolling, the workpiece is freed from the rolls and removed from the mill.

Предлагаемый стан позволяет сократить время настройки положения приемной призмы относительно проводок, так как эта настройка выполняется вне стана на разметочной плите с помощью измерительного инструмента, т.е. обеспечить повышение коэффициента ис10 пользования рабочего времени стана.The proposed mill allows to reduce the time for adjusting the position of the receiving prism relative to the wiring, since this adjustment is performed outside the mill on the scribing plate using a measuring tool, i.e. to ensure an increase in the coefficient of use of the mill’s working time.

Claims

The invention relates to the main process equipment of the rolling mill, namely to mills for the manufacture of shaft steps by cross wedge rolling. The purpose of the invention is to increase the utilization rate of the mill's working time by reducing the time to adjust the position of the receiving prism relative to the postings. FIG. 1 shows a cross wedge rolling mill, the plan view in FIG. 2 is section A-A in FIG. G; FIG. 3 is a section BB in FIG. 2, the mill comprises a frame 1, drive work rolls 2, a centering unit for the workpiece, which is made into a view, e of the frame frame 3 with the wires 4 installed in the groove and the receiving prism 5. The blank 6 is fed to the receiving prism 5 and fixed along the rolling axis 1-1. From the receiving prism, the workpiece is fed into the space between the wires 4, captured by the rotating rollers 2 and rolled into a shaped article. At the end of the rolling, the cooking is released from the rolls and removed from the mill. The proposed mill allows reducing the time required for adjusting the position of the receiving pris1U with respect to the wiring, since this setting is performed outside the mill on the marking plate using a measuring tool, i.e. to ensure the increase in the utilization rate of the mill. Claims for cross-wedge rolling mill comprising a frame, driving work rolls, a workpiece centering unit made in the form of a frame with installed wiring housed in a slot of the frame and a receiving prism, characterized in that in order to increase the utilization rate of the working mill time by reducing the positioning time of the receiving prism relative to the postings, the receiving prism is mounted on the frame of the centering unit of the workpiece.
