Problems solved by technology
[0003] However, with the development of the market, customers' demand for high-speed casting machines has increased, and the control of electric cylinders can no longer meet the requirements of use. Cylinder can achieve) and other advantages, more recognized by the owner, which requires us to develop the crystallizer liquid level servo automatic control system as soon as possible (the development of the stopper servo cylinder is an important part of the system, its design is directly related to affect the normal operation of the system) to make up for the technical gap in this field and expand the scope of technology supply to better meet market demand

Embodiment Construction
[0011] The present invention will be described in detail below in combination with specific embodiments.
[0012] The inventive device such as figure 1 and figure 2 As shown, one end of the telescopic rubber protective sleeve 2 is fixed on the front cylinder head 5, and the other end is fixed on the front fork 1, and extends and retracts with the piston rod to prevent dust and iron powder from damaging the piston rod; the ball valve 6 is connected to the cylinder Body 7 and ball valve 6 are used for two-chamber pressure relief when opened, and are used for two-chamber pressure isolation when closed; cylinder body 7, front end cover 5 and rear cylinder cover 9 are fixed by studs 4 and nuts 3, and nuts 3 can support the cylinder 8 Fine-tuning up and down to make up for machining errors. The rear cylinder head sheath 10 is fixed on the rear cylinder head 9 by screws to protect the piston cylinder from damage and facilitate manual removal of the cylinder; the position transmissi...

The present invention discloses a stopper servo hydraulic cylinder. One end of a protective cover is fixed on a front cylinder cover, and the other end is fixed on a front fork to extend and retract with a piston rod to prevent dust and iron powder from damaging the piston rod. A ball valve is connected with a cylinder body. The ball valve opens to release pressure for two chambers and closes to realize pressure isolation between two chambers. The cylinder body is fixed with the front end cover and a rear end cover through a stud and a nut. A rear cylinder cover sheath is fixed on the rear cylinder cover through a screw to protect the piston cylinder from being damaged and to facilitate manually detaching the cylinder. A transmission sheath is fixed to the rear end of the rear cylinder cover sheath through the screw to protect a built-in displacement sensor from being damaged. A wire jacket is welded on the transmission sheath to allow a transmission cable to pass through and to wear afireproof covering outside. The beneficial effects of the present invention are advantages of light weight, new structure, long service life and the like.
Description
technical field [0001] The invention belongs to the technical field of metallurgical equipment and relates to a novel stopper rod servo hydraulic cylinder. Background technique [0002] At present, in the metallurgical industry, there are two types of automatic control of continuous casting machine stopper rods: electric cylinder control and servo cylinder control. Up to now, the standard configuration of the stopper rod mechanism of continuous casting machine has been electric cylinder control. For conventional casting machines To put it bluntly: the control of the electric cylinder is stable, reliable, and cost-effective, which can fully meet the requirements of the casting machine. [0003] However, with the development of the market, customers' demand for high-speed casting machines has increased, and the control of electric cylinders can no longer meet the requirements of use. Cylinder can achieve) and other advantages, more recognized by the owner, which requires us t...
