Description

Изобретение относится к конструкции блоков штампов и может быть использовано во всех отраслях промышленности при листовой штамповке. . _The invention relates to the construction of blocks of stamps and can be used in all industries with sheet stamping. . _

Известен блок штампов, содержащий ³две плиты, связанные с возможностью относительного перемещения двумя направляющими. парами и установленные консольно на двух колонках, входящих в состав направляющих пар (1) и [2].Known block stamps containing ³ two plates associated with the possibility of relative movement of the two guides. in pairs and mounted cantilever on two columns that are part of the guide pairs (1) and [2].

Однако данный блок штампов не исключает возможности перекоса подвижной плиты и не позволяет повысить стойкость штампа.However, this block of dies does not exclude the possibility of skewing the movable plate and does not improve the stability of the stamp.

Цель изобретения - уменьшение перекоса подвижной плиты и повышение стойкости штампа.The purpose of the invention is to reduce the skew of the movable plate and increase the durability of the stamp.

Поставленная цель достигается тем, что блок снабжен дополнительной нап- 20 равняющей парой, ось которой расположена на равном расстоянии от осей двух других направляющих пар и смещена относительно плоскости, проходящей через эти оси, причем ось допол- 25 нительной направляющей пары смещена относительно плоскости, проходящей через оси двух других направляющих пар, предпочтительно в сторону, противоположную консольной части плит. 30This goal is achieved by the fact that the unit is equipped with an additional alignment pair, the axis of which is located at an equal distance from the axes of two other guide pairs and is offset relative to the plane passing through these axes, and the axis of the additional guide pair is offset from the plane passing through the axis of two other guide pairs, preferably in the direction opposite to the cantilever part of the plates. thirty

На фиг. 1 схематически изображен блок штампов; на фиг. 2 - то же, вид сверху.In FIG. 1 schematically shows a block of dies; in FIG. 2 - the same, top view.

Блок содержит направляющие колонки 1 и втулки 2, установленные соответственно в неподвижной 3 и подвижной 4 плитах. Кроме того, блок имеет дополнительную направляющую пару колонку 5 и втулку 6.The block contains guide columns 1 and bushings 2, respectively mounted in fixed 3 and movable 4 plates. In addition, the unit has an additional pair of guide column 5 and sleeve 6.

При работе блока с предлагаемым расположением направляющих изгибающий момент становится меньше и подвижная плита имеет меньший перекос относительно неподвижной плиты.When the unit operates with the proposed arrangement of the guides, the bending moment becomes smaller and the movable plate has less skew relative to the fixed plate.

Claims

This invention relates to the construction of a block of dies and can be used in all industries in sheet metal forming. A block of dies is known, containing two plates connected with the possibility of relative movement by two guides, in pairs and mounted cantilever on two columns that are part of guide pairs 1 and 2. However, this block of dies does not exclude the possibility of skewing the movable plate and does not allow It does not increase the durability of the stamp. The purpose of the invention is to reduce the skew of the movable plate and increase the durability of the stamp. . The goal is achieved by the fact that the block is equipped with an additional guide pair, the axis of which is located at equal distance from the axes of the other two guide pairs and displaced in a relatively plane passing through these axes, and the axis of the additional guide pair is shifted relative to the plane passing through the axes of the two other directional pairs, preferably in the direction opposite to the cantilever part of the plates. FIG. 1 schematically shows a block of dies; in fig. 2 - the same, top view. The block contains guide columns 1 and bushings 2 installed in fixed 3 and movable 4 plates, respectively. In addition, the unit has an additional direction for each pair of column 5 and sleeve 6.. When the unit operates, the proposed arrangement of the guiding bending moment becomes smaller and the movable plate has a smaller skew with respect to the fixed plate. Claims 1. A block of dies containing two plates associated with the relative movement of two guide pairs and mounted cantilever on two columns that are part of the guide pairs, about tons of l and -. in order to reduce the skew of the movable plate and increase the durability of the punch, the block is equipped with an additional guide pair, the axis of which is located at equal distance from the axes of the other two directions of the pairs and shifted relative to the plane passing through these axes.

2. The unit according to claim 1, characterized in that the axis of the additional guide pair is offset relative to the plane passing through the axes of the other two guide pairs, in the direction opposite to the cantilevered end of the plates.
