Description

Adjusting device for guide gap between square column and movable beam of hydraulic press

technical field

The present invention relates to a clearance adjustment device used on hydraulic press equipment, in particular to a guide clearance adjustment device between a square column and a movable beam of a hydraulic press.

Background technique

The adjustment of the guide gap between the square column and the movable beam of the existing hydraulic machine is carried out manually. The adjustment of the guide gap requires tools such as wrenches, crowbars, and feeler gauges. At least two people are required to cooperate to complete the task. The problem of time and labor consumption, especially this adjustment method, cannot ensure the reliable fit between the adjustment guide inclined iron and the fixed inclined iron, resulting in uneven stress on the fasteners when the hydraulic press is working, reducing the working life of the hydraulic press.

A wrench head is provided on the head of the lead screw, a counterbore with an internal thread is provided on the inner surface of the inverted wedge-shaped guide block, and a stud passing hole is provided on the movable beam and the wedge-shaped nut block, and the double-headed One end of the tension bolt is screw-connected with the inner threaded counterbore provided on the inner surface of the inverted wedge-shaped guide block, and the other end of the double-ended tension bolt passes through the stud through the hole and is screw-connected with the nut.

A guide anti-wear plate is provided on the outer surface of the inverted wedge-shaped guide block, a gap adjustment device is provided on the four gaps formed by the square column of the hydraulic press and the movable beam, and a lubricating oil injection hole is provided in the double-headed tension bolt.

The invention can facilitate the adjustment of the guiding gap of the movable crossbeam of the hydraulic press, and ensures the evenness of the gap after adjustment and the bonding of the guiding inclined iron and the adjusting inclined iron, so that the service life of the hydraulic press is improved.

Detailed ways

A device for adjusting the guide gap between a hydraulic press square column and a movable beam, comprising a hydraulic press square column 2 and a movable beam 1, a pressing plate 5 is arranged on the top surface of the movable beam 1, and a through hole 8 and a groove 7 are arranged on the pressing plate 5, One end of the pressing plate 5 is fixedly arranged on the top surface of the movable beam 1 by the fixing bolt 6, and the other end of the pressing plate 5 and the groove 7 on the pressing plate 5 are arranged above the gap 3 between the square column 2 of the hydraulic press and the movable beam 1. In the gap between the square column 2 of the hydraulic press and the movable beam 1, a wedge wire female block 11 and an inverted wedge-shaped guide block 12 are movable, and the wedge-shaped surface of the wedge-shaped wire female block 11 is movably matched with the wedge-shaped surface of the inverted wedge-shaped guide block 12. An auxiliary pressing block 4 is arranged in the groove 7, and the leading screw 9 passes through the auxiliary pressing block 4 and is screwed with the wedge-shaped nut block 11. A wrench head 10 is arranged at the head of the leading screw 9, and inside the inverted wedge-shaped guide block 12 A counterbore 18 with an internal thread is provided on the side, and a stud passing hole 15 is provided on the movable beam 1 and the wedge-shaped nut block 11, and one end of the double-ended tension bolt 14 is connected to the inner surface of the inverted wedge-shaped guide block 12. The counterbore 18 of the band internal thread that is provided is screwed, and the other end of the double-ended tension bolt 14 passes through the stud and is screwed with the nut 16 after passing through the hole 15 .
