Description

Guiding mechanism and four-column press with same

Technical Field

The utility model relates to the field of machinery, in particular to a guide mechanism and a four-column press with the same.

Background

The precision of a guide structure of a traditional four-column press depends on the machining precision and the assembling precision, the machining precision is high in requirement, the installation difficulty is high, and after the guide structure is installed, the guide gap between a guide sleeve and a stand column cannot be adjusted, so that the best guide precision is difficult to obtain.

In the use process of the press, the upright post and the guide sleeve generate friction, so that the abrasion is inevitable. After the uide bushing wearing and tearing reach the certain degree, because of the guide clearance is unadjustable, the direction precision worsens, can not satisfy the production demand, must change the uide bushing this moment, must dismantle relevant parts such as fuselage and slider during the change, the dismouting is inconvenient, wastes time and energy. In addition, the guide sleeve is made of special materials, so the replacement cost is high.

Disclosure of Invention

The embodiment of the utility model provides a guide mechanism and a four-column press with the same, which at least solve the problem of difficulty in installation of a guide sleeve.

The embodiment of the utility model provides a guide mechanism which comprises an upright post, a sliding block, a guide sleeve and a gland, wherein the sliding block and the guide sleeve are respectively connected to the gland, the guide sleeve is slidably sleeved on the upright post, the guide sleeve comprises a first inclined surface positioned on one side away from the upright post, the sliding block comprises a second inclined surface in contact with the first inclined surface, and the guide sleeve can move relative to the gland, so that the interval between the guide sleeve and the upright post is adjusted under the abutting of the second inclined surface.

Further, the guide sleeve is provided with an adjusting gap so that the guide sleeve can deform when being extruded.

Further, guiding mechanism still includes adjusting pole and adjustable ring, the adjustable ring is fixed in the gland, it wears to locate to adjust the pole the adjustable ring is connected the uide bushing, it drives to adjust the pole removal back the uide bushing is followed stand axial displacement.

Further, along keeping away from the gland direction, first inclined plane and second inclined plane are close to the stand gradually.

Another embodiment of the present invention provides a four-column press, including the above-mentioned guiding mechanism.

Advantageous effects

The guide mechanism (1) is simple in structure, few in positioning matching surface required during installation, and easy and convenient to install.

(2) The structure can conveniently adjust the guide clearance between the guide sleeve and the upright post so as to reach the optimal guide precision, thereby improving the product percent of pass and prolonging the service life of the die.

(3) When the guide sleeve is worn to a certain degree and cannot meet production requirements, the optimal guide precision can be achieved only by adjusting the position of the guide sleeve relative to the gland, and the guide sleeve does not need to be replaced. Firstly, the manufacturing cost is saved, secondly, the dismounting, mounting and transporting cost is saved, and the maintenance cost is low.
