Abstract

The invention belongs to the technical field of molds, and discloses a guide pillar for bending a steel bar mold. A guide hole is formed in the center of an end cover, and a guide pillar body A is installed in the guide hole. A sealing washer is arranged between the inner wall of the guide hole and the outer wall of the guide pillar body A. A stopping block is installed at the top of the guide pillar body A. A reset spring is arranged between the stopping block and the end cover. The bottom of the guide pillar body A is connected with a guide pillar body B. The guide pillar body B makes contact with the inner wall of a guide sleeve. An oil storage part is arranged between the inner wall of the guide sleeve and the guide pillar body B. The side, making contact with the guide pillar body B, of the oil storage part is provided with rubber. An opening is formed in the top end of the oil storage part. A baffle is obliquely arranged on the inner wall of the guide sleeve. The baffle is fixed to the side wall of the upper portion of the oil storage part. One side, fixed to the inner wall of the guide sleeve, of the baffle is lower than the other side of the baffle. The opening of the oil storage part abuts against the baffle. Fluid oil is contained in the oil storage part. The problems that the abrasion reducing effect of the guide pillar is bad, cost is high and the structure is complex in the prior art can be solved.

Description

technical field [0001] The invention belongs to the field of molds, and in particular relates to a guide post of a mold for bending steel bars. Background technique [0002] Steel bar is a kind of strip-shaped steel, which is widely used in automobile manufacturing, decoration, and construction industries, and the shapes of steel bars that need to be used in different occasions are different, so there is a mold for bending steel bars, steel bars The bar needs precise positioning during the bending process to ensure the accuracy of the bending angle and improve the accuracy of the parts. The mold guide column is an important part in the process of mold closing, and its main function is to position and guide the movement of the mold. When the mold is clamped, it usually produces a certain impact force, which deforms the guide post, and in the process of reciprocating movement of the guide post in the guide sleeve, friction will be generated, which will cause wear to the guide...
