Description

Изобретение относитс к кузнечнопрессоврму машиностроению, в частности к конструкции механизмов регулировки закрытой высоты пресса.The invention relates to forging and pressing machinery, in particular, to the design of mechanisms for adjusting the closed height of the press.

Известен механизм регулировки закрытой высоты пресса, содержащий смонтированный ,в направл ющих станины ползун, сочлененный с шатуном эксцентриковой осью, на которой закреплен приводной рычаг 1.A mechanism for adjusting the closed height of the press is known, which comprises a slide mounted in the bed guides, which is articulated with a connecting rod by an eccentric axis on which the drive lever 1 is fixed.

Недостатком известного механизма регулировки зак1зытой высоты вл етс сложность конструкции.A disadvantage of the known height adjustment mechanism is the complexity of the design.

Цель изобретени - упрощение конструкции . . The purpose of the invention is to simplify the design. .

Поставленна цель достигд1етс тем, что в механизме регулировки закрытой высоты пресса, содержащем смонтированный в направл ющих станины ползун, сочлененный с шатуном эксцентриковой осью, на которой закреплен приводной рычаг, привод последнего выполнен в виде ссшазок, смонтированных на станине с возможностью возвратно-поступательного перемещени , на салазках выполнен паз, параллельный направлению перемещени ползуна,а-на рычаге выступ ,размещенный в упом нутом пазу.The goal is achieved by the fact that in the mechanism for adjusting the closed height of the press, which contains a slide mounted in the bed guides, articulated with a connecting rod with an eccentric axis on which the drive lever is fixed, the drive of the latter is made in the form of shafts mounted on a frame with the possibility of reciprocating movement, on the slide, a groove is made parallel to the direction of movement of the slide; on the lever, a protrusion located in said slot.

На фиг. 1 показан механизм регули ровки закрытой высоты пресса, общийFIG. 1 shows the mechanism for adjusting the closed height of the press;

Вий; на фиг. 2 - разрез А-А на фиг.If на фиг. 3 - разрез Б-В на фиг. 1.Wii; in fig. 2 is a section A-A in FIG. If in FIG. 3 shows a section B-B in FIG. one.

Механизм регулировки закрытой высоты , пресса содержит смонтированный в направл ющих 1 станины 2 ползун 3, шатун 4, жсцент-р ковую ось Б, посредством которой шатун 4 с6членен с ползуном 3, приводной рычаг 6, сгшазки 7 смонтированные в направл ющих В и 9, The mechanism for adjusting the closed height, the press contains mounted in the guides 1 of the bed 2, the slider 3, the connecting rod 4, the forging axis B, through which the connecting rod 4 has 6 members with the slide 3, the drive lever 6, the knobs 7 mounted in the guides B and 9,

10 закрепленных на станине 2. В салазках 7 выполнен паз 10, паргшлельный направлениюперемещени ползуна 3, а на приводном рычаге 6 - выступ в виде ролика 11.10 mounted on the bed 2. In the slide 7, a groove 10 is made, the direction of movement of the slide 3 is parked, and on the drive lever 6 there is a protrusion in the form of a roller 11.

В салазках 7 закреплена гайка 12, св занна с винтом 13, установленным в опоре 14 и соединенным с выходным МО тор-редуктора. 15.A nut 12 is fixed in the slide 7 and is connected to the screw 13 mounted in the support 14 and connected to the output torus gearbox MO. 15.

Регулировка закрытой высоты пресса Adjust the closed height of the press

20 происходит следующим образом.20 occurs as follows.

Claims

The motor gearbox 15 is turned on, the rotation is transmitted from it to the screw 13, which moves the nut 12 and the slide 7 totoral. The slide 7, moving through the roller 11 and the lever 6, turns in the slider 3 the eccentric axis 5. This changes the distance from the axis of the lower hole in the connecting rod 4 to the shtampa, and therefore the height of the press is closed. When the press is in operation, the roller 11 is moved along the groove of the slide 7 without rotating the lever 6 around the eccentric axis 5, and the screw 13 through the nut 12 holds the slide away from movement. The technical and economic effect of implementing the invention is achieved by simplifying the design of the mechanism. Claims The mechanism for adjusting the height of the press, containing a slide mounted in the bed guides, articulated with a connecting rod by an eccentric axis on which the drive lever is attached, characterized in that, in order to simplify the design, the lever drive is designed as a slide mounted on the frame with the possibility reciprocating movement; a slot is made on the slide parallel to the direction of movement of the slide; and on the lever there is a protrusion located in said slot.
