Description

Three-Beam and Three-Column Diagonal Press LU503113

TECHNICAL FIELD

The invention belongs to the technical field of forging machinery manufacturing, in particular to a three-beam three-column diagonal press.

BACKGROUND

Press, including punch press, hydraulic press, etc., is a universal forging machine with exquisite structure, which is widely used in punching, blanking, cutting, bending and forming processes. By exerting strong pressure on the metal blank, the metal is plastically deformed and broken to be processed into parts, which has outstanding characteristics such as high production efficiency. At present, the structure of the press is usually three beams and four columns or three beams and two columns. Four or two columns are used to firmly connect the upper, lower and movable beams together through column nuts to form a rigid closed space. When the workpiece is processed, the columns play a guiding and structural supporting role. Workers or manipulators can only place the workpiece on the workbench from the front and rear positions of the press, and the workbench has a rectangular or square cross section. This structure has certain limitations for operators and operating space, and the overall center of gravity of the press is unstable, so the columns and beams are prone to cracks and fractures under the reciprocating load.

China Patent Application No. "201610687252.2" discloses a forging hydraulic unit with three beams, three columns and multiple manipulators, which is composed of a forging hydraulic press and manipulators. The forging hydraulic press is an up-driving and up-pressing hydraulic press, and its mechanical structure includes an upper fixed beam, a movable beam, a lower fixed beam, columns, a main hydraulic cylinder, a return hydraulic cylinder and a hammer head. The hammer head is fixed below the movable beam, which is fixed below the plunger of the main hydraulic cylinder, and the cylinder of the main hydraulic cylinder is fixed blow the upper fixed beam. The cylinder of return hydraulic cylinder is fixed blow the upper fixed beam and its piston rod and the movable bean are fixed. There are three columns, which form a triangular prism in space. The axes of the three columns are parallel to each other in space. The upper fixed beam 15031 13 fixed on the upper part of the three columns, the movable beam passes through the two columns with the largest distance and can slide up and down, and the lower fixed beam is fixed on the lower part of the three columns. The movable beam of the three-beam and three-column hydraulic press disclosed in the above patent is elliptical, the fixed beam is rectangular, and the column space structure is a right triangle structure. The movable beam only passes through the two columns with the largest spacing, and its operability, space utilization and stability are still similar to those of the traditional three-beam four-column and three-beam two-column presses.

During operation, the workpieces can only be clamped between the two columns with the largest spacing, and the mechanical structure of the hydraulic press is biased to one side of the triangle, which leads to low stability.

SUMMARY

The invention aims to effectively overcome the shortcomings of the prior art, and solve the technical problems in the prior art that the columns and beams of a three-beam and four-column or three-beam and two-column press are prone to crack and break under the reciprocating load, and the stability of the three-beam and three-column press is poor. The invention provides a three-beam and three-column diagonal press.

The invention is realized by the following technical scheme.

A three-beam and three-column diagonal press comprises an upper beam, a lower beam, a movable beam, a hydraulic cylinder and columns, wherein the press is arranged in a regular triangular prism structure in space, the press is arranged in the vertical direction, three columns are respectively arranged at the edge positions of the regular triangular prism, the upper beam is fixedly installed above the columns, the lower beam is fixedly installed below the columns, and the movable beam is arranged on the columns between the upper beam and the lower beam; the upper beam, the lower beam and the movable beam are all in the shape of an equilateral triangle; the hydraulic cylinder is vertically and downwards arranged above the upper beam, the piston rod of the hydraulic cylinder runs through the upper beam and extends above the movable beam,

the piston rod is fixedly connected with the upper surface of the movable beam through a flange, 503113 and the piston rod drives the movable beam to slide up and down along the columns.

Further, the center of gravity of the press is on the same axis as that of the regular triangular prism structure.

Furthermore, a hammer or an upper anvil is installed below the movable beam, and a lower anvil is installed above the lower beam.

Further, the lower beam is installed on the base, and a connecting nut is arranged below the base.

Compared with the prior art, the invention has the advantages that: according to the three-beam and three-column diagonal press provided by the invention, the upper beam, the movable beam, the lower beam and the three columns form a regular triangular prism structure in the spatial position, and the triangle has the characteristic of stability, so that the stability is higher than that of the three-beam and four-column presses and the three-beam and two-column presses, and the three-beam and two-column presses also have higher strength and rigidity, and the structure and the center of gravity can be kept stable and the whole frame cannot be deformed under a larger load. In addition, the distance between the three columns is equal, and workpieces can be clamped between two columns, so that the space operability is improved, and the structure is simple, the manufacturing is easy, and the cost is reduced.
