Elastic floating support device for drawing and extending roller die of drawing and extending hydraulic press

Abstract

The invention discloses an elastic floating support device for a drawing and extending roller die of a drawing and extending hydraulic press. The elastic floating support device comprises a base seat, a spring seat, a support plate and a guide cylinder, wherein the base seat is fixedly installed on a front beam base plate of the drawing and extending hydraulic press, and a guide through hole is arranged on the pedestal; the spring seat is fixedly installed on the front beam base plate and is located in the guide through hole; the upper end surface of the support plate is a cambered surface matched with a shell of the drawing and extending roller die; and the guide cylinder is sheathed in the guide through hole, the upper end surface is fixedly connected with the support plate, the lower end is in sliding fit with the spring seat, and a spring is pretightened between the guide cylinder and the spring seat. In the invention, the guide cylinder and the spring seat are in sliding fit, the guide cylinder is connected with the support plate for supporting the drawing and extending roller die, and the pretightened spring is installed in the guide cylinder. When the drawing and extending roller die undergoes impacts and vibrations during working, the support plate can buffer the impacts and vibrations of the drawing and extending roller die through the guide cylinder and the support plate in sliding fit with the fixedly installed spring seat and via buffering and resetting of the spring in the guide cylinder.

Description

technical field [0001] The invention relates to a horizontal drawing hydraulic press, in particular to a supporting device for a drawing roll mold in the horizontal drawing hydraulic press. Background technique [0002] In my country, high-pressure gas cylinders such as high-pressure oxygen cylinders and natural gas cylinders are widely used in medical treatment and life. High-pressure gas cylinders are usually stretched and formed by drawing hydraulic presses. The overall structural performance of the drawing hydraulic presses used to produce high-pressure gas cylinders has a great influence on the structural performance of high-pressure gas cylinders. The main body mold of the drawing hydraulic press includes a drawing ring die and a drawing roller die, both of which are installed on the front beam, and the cup-shaped preform is worn on the drawing mandrel during drawing. Thinning and stretching are carried out by drawing ring touch and drawing roller molds, and finally f...

AI Technical Summary

Problems solved by technology

Due to the large amount of stretching and deformation of the preform, the drawing roller mold bears a large impact and vibration on the preform. Through the transmission of force, the impact and vibration on the front beam is also very large.

The service life of the front beam and the drawing roller mold is greatly reduced due to the large shock and vibration

In addition, because the wall thickness of the drawing preform is uneven, and the drawing roller mold is rigidly installed on the front beam and remains unchanged, it is easy to deform the drawing mandrel when drawing at the drawing roller mold. , affecting the accuracy of the inner hole of the high-pressure gas cylinder

At the same time, the uneven wall thickness of the drawing preform will seriously impact and vibrate the drawing roller mold and front beam, reducing the service life of the drawing roller mold and front beam

In addition, the seal of the pipeline on the front beam is also easy to loosen and leak under the influence of shock and vibration, which often requires time-consuming maintenance, which reduces production efficiency and increases manual workload

Finally, since the drawing roller mold is rigidly installed on the front beam, the drawing roller mold cannot adjust and improve the uniformity of the wall thickness of the preform, resulting in poor wall thickness uniformity of the drawn high-pressure gas cylinder, and the Poor bottle quality will directly affect the market and revenue of the product
