Изобретение относитс к нагревательным печам, например дл нагрева заготовок перед штамповкой и может найти применение в машиностроительной и металлургической промышленност х .The invention relates to heating furnaces, for example for heating billets prior to stamping, and may find application in the engineering and metallurgical industries.

Известна нагревательна печь с гидравлическим шагающим подом, состо ща из подвижных и неподвижных балок П .A hydraulically walking bottom heating furnace is known, consisting of movable and fixed beams.

Наиболее близкой по технической сущности и достигаемому результату к предлагаемому вл етс печь дл термообработки заготовок с шагающим подом, включающим подвижные балки с гидроцилиндрами их поступательного и возвратного перемещени , неподвижные балки, установленные на каркасе печи, и подъемную раму с катками ..The closest in technical essence and the achieved result to the proposed is a furnace for heat treatment of blanks with a walking hearth, including movable beams with hydraulic cylinders of their translational and return movement, fixed beams mounted on the furnace frame, and a lifting frame with rollers.

Недостатками известных устройств вл етс то, что гидроцилиндры, перемещающие шагающий под, закреплены вне подъемной рамы на отдельном фундаменте и не имеют возможности сооско работать в горизонтальной плоскости при рабочем и обратном ходах, что ПРИВОДИТ; к понижению надежности печи.The disadvantages of the known devices is that the hydraulic cylinders, which move the walking under, are fixed outside the lifting frame on a separate foundation and do not have the ability to work coaxially in a horizontal plane during working and reverse strokes, which LEADS; to reduce the reliability of the furnace.

Цель изобретени - повышение надежности работы печи.The purpose of the invention is to increase the reliability of the furnace.

Поставленна цель достигаетс тем, что в нагревательной печи, содержащей каркас, под, выполненный в виде стационарных балок, установленных на каркасе печи, и балок с гидроцилиндрами маханизма их возвратно-поступательного перемещени , и раму с катками и приводом подъема, гидроцилиндры механизма возвратно-поступательного перемещени балок установлены на раме симметрично относительно ее поперечной оси.The goal is achieved by the fact that in a heating furnace containing a frame under, made in the form of stationary beams installed on the furnace frame and beams with hydraulic cylinders of the machinism of their reciprocating movement, and a frame with rollers and lifting drive, the cylinders of the reciprocating mechanism The beams are mounted on the frame symmetrically about its transverse axis.

На фиг. 1 изображена нагревательна печь, общий вид; на фиг. 2 разрез А-А на фиг. 1.FIG. 1 shows a heating furnace, general view; in fig. 2, section A-A in FIG. one.

Claims

The heating furnace contains a lifting frame with rollers 2 and lifting, 3 but a lever system 3 with lifting cylinders. On rollers 2 lifting frame 1, a hearth frame 5 with movable beams 6 is supported. The bottom frame 5 is connected to the stems of hydraulic cylinders of translational 7 and return 8, installed on the lifting frame 1 along its longitudinal axis and symmetrically relative to the transverse axis. The device works as follows. The cylinder 4, through the lever system 3, presses the frame 1 and at the same time the movable beams 6 with the hearth frame 5 supported on the rollers 2. Then turn on the hydraulic cylinder 7 and the frame 5 with beams 6 moves one step forward (left), while the rod of the hydraulic cylinder 8 moves to same direction. Thereafter, the cylinders in the reverse order lower the sub-frame 5, and the hydraulic cylinder 8 returns the sub-frame 5 with movable beams 6 to the initial position and at the same time compresses the rod of the hydraulic cylinder 7. After a predetermined holding of the blanks in the cycle repeats. 5 The economic effect from the use of the proposed device is approximately 585 rubles. in year. Claims of the invention A heating furnace comprising a cylinder, below, made in the form of stationary beams installed on the furnace frame, and beams with hydraulic cylinders of their reciprocating movement and a frame with rollers and a lifting drive, characterized in that, in order to increase reliability operation of the furnace, the cylinders of the mechanism for reciprocating the movement of the beams are mounted on the frame symmetrically about its transverse axis.
