Abstract

The invention relates to a two-roller plate bending machine with a single cylinder pushing the lower roll, which relates to the technical field of plate bending machines, in particular to a two-roller plate bending machine with a single cylinder pushing the lower roll. The lower roller (3) is fixed to the side plates (7) on both sides through the inner roller shaft (4), the upper corner of the side plate (7) is connected to the fixed bracket (1) through the rotating shaft (2), and the lower end of the side plate (7) A driving lower rod (5) is connected between them, and a hydraulic oil cylinder (6) is arranged in the middle of the driving lower rod (5). It changes the drive of the lower roll into a single-cylinder drive, which has simple structure, low cost and good stability.

Description

A two-roll plate bending machine with a single cylinder pushing the lower roll

Technical field:

The utility model relates to the technical field of plate rolling machines, in particular to a two-roll plate rolling machine in which a single cylinder pushes a lower roll.

Background technique:

With the development of the machinery industry, plate rolling machines have been used by many machinery factories. The two-roll plate rolling machine works through the extrusion of the upper roll and the lower roll. The upper roll is a fixed roll, and the lower roll is a driving roll that moves up and down. The traditional lower roller driving device is equipped with lifting cylinders at both ends of the lower roller to drive the lower roller. However, due to the asynchronous lifting of the cylinders at both ends, it is prone to imbalance, which will bring errors to the operation and affect the product quality.

Utility model content:

The purpose of this utility model is to provide a two-roll plate rolling machine with a single cylinder pushing the lower roll, which changes the drive of the lower roll into a single cylinder drive, which has simple structure, low cost and good stability.

In order to solve the existing problems in the background technology, the utility model adopts the following technical solutions: it includes a fixed bracket 1, a rotating shaft 2, a lower roller 3, a roller shaft 4, a driving lower rod 5, a hydraulic cylinder 6 and a side plate 7; The roller 3 is fixed to the side plates 7 on both sides through the internal roller shaft 4, the upper corner of the side plate 7 is connected to the fixed bracket 1 through the rotating shaft 2, and the lower end of the side plate 7 is connected with the driving lower rod 5, and the middle part of the driving lower rod 5 is set There are hydraulic cylinders 6.

During work, the hydraulic cylinder 6 drives the lower rod 5 to push up the side plate 7, and the side plate 7 drives the lower roller 3 to move in a curve around the rotating shaft 2.

The utility model changes the driving of the lower roller into a single-cylinder driving, and has simple structure, low cost and good stability.

Description of drawings:

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a sectional view taken along line A-A of Fig. 1 .

Detailed ways:

Referring to Fig. 1-2, this specific embodiment adopts the following technical solutions: it includes a fixed bracket 1, a rotating shaft 2, a lower roller 3, a roller shaft 4, a driving lower rod 5, a hydraulic cylinder 6 and a side plate 7; the lower roller 3 The inner roller shaft 4 is fixed to the side plates 7 on both sides. The upper corner of the side plate 7 is connected to the fixed bracket 1 through the rotating shaft 2. The lower end of the side plate 7 is connected to the driving lower rod 5, and the middle part of the driving lower rod 5 is provided with a hydraulic pressure Cylinder 6.

During work, the hydraulic cylinder 6 drives the lower rod 5 to push up the side plate 7, and the side plate 7 drives the lower roller 3 to move in a curve around the rotating shaft 2.

In this specific embodiment, the drive of the lower roll is changed to a single-cylinder drive, which has a simple structure, low cost and good stability.
