Problems solved by technology

The support beam and its cylinder liner are welded structural parts or castings, and the cylinder body of the main hydraulic cylinder is a forging, which has a large machining allowance and wastes materials. Although it is convenient to process separately, the cost is high, and the force on the cylinder body and cylinder liner separately also wastes materials.

Embodiment 1

[0016] like figure 1 As shown, the main hydraulic cylinder with the support beam of the hydraulic three-roll plate bending machine includes the main hydraulic cylinder, the support beam, and the support beam forms a closed force-bearing frame with the column and the bed (not shown). There is a main hydraulic cylinder at each end of the upper roll, figure 1 One of them is shown. The main hydraulic cylinder at both ends of the upper roll drives the upper roll down. The main hydraulic cylinder is a piston cylinder. The cylinder body 2 is a steel casting. The body and the bottom of the cylinder are cast as one, and the cylinder body 2 is inlaid with the inner cylinder liner 12, which is light in weight and can be made of better materials. The standard low-pressure thin-walled cylinder barrel produced by a professional manufacturer is used as the inner cylinder of the high-pressure main hydraulic cylinder. The inner cylinder liner 12 and the inner wall of the cylinder body 2 are b...

Embodiment 2

[0018] like figure 2 As shown, the main hydraulic cylinder with the support beam of the hydraulic three-roller plate bending machine includes the main hydraulic cylinder, the support beam, the support beam 1, the column 13, and the bed (not shown) to form a closed stress-bearing frame. There are two main hydraulic cylinders in the span direction of the support beam at both ends of the upper roller. figure 2 The two main hydraulic cylinders at one end are shown, the main hydraulic cylinders at both ends of the upper roller drive the upper roller to press down, the main hydraulic cylinder is a piston cylinder, the cylinder body 2 is a steel casting, and the main hydraulic cylinder body and cylinder sleeve are combined into a One body, the main hydraulic cylinder cylinder body and the cylinder bottom are cast as one, the two cylinder bodies are cast as one body, and the inner cylinder liner 12 is inlaid in the cylinder body 2. The inner cylinder liner 12 is light in weight and...

Embodiment 3

[0020] like image 3 Shown, the main hydraulic cylinder of the band supporting beam of four-column hydraulic press, it comprises main hydraulic cylinder, supporting beam, and supporting beam 1 forms a closed stressed framework with column 13, lower beam (not shown). The cylinder block 2 is welded with the support beam 1 and becomes a part of the support beam. The cylinder bottom 15 is connected with the cylinder liner 2 with bolts, the guide sleeve 8 is connected with the cylinder liner 2 with bolts, and the inner cylinder liner 12 is connected with the inner wall of the cylinder body 2. Adhesives 3 are used to bond together, and the piston rod 4 is connected to the movable beam 14 through the semicircular snap ring 9 to drive the movable beam 14 to move.

Abstract

A master hydraulic cylinder with supporting beam is a piston-type one and features that its cylinder body with internal cylinder sleeve is directly fixed to machine frame.

Description

technical field [0001] The invention belongs to the main executive part of the hydraulic pressure processing equipment - the main hydraulic cylinder, in particular to a main hydraulic cylinder with a support beam. Background technique [0002] Existing hydraulic pressure processing equipment, such as hydraulic presses, hydraulic plate rolling machines, hydraulic balers, etc., the main actuator is the main hydraulic cylinder, the main hydraulic cylinder is installed on the support beam, installed in the cylinder sleeve fixed on the support beam, Install the support beam of the main hydraulic cylinder and the column, lower beam or bed to form a closed force-bearing frame such as frame hydraulic press, hydraulic plate rolling machine, or an open force-bearing frame such as cantilever hydraulic press, to carry out pressure processing and support on the workpiece The beam and the cylinder liner fixed on the support beam bear the bending load, the hydraulic cylinder bears the hydr...
