Discharging device and discharging method of suspended centrifugal casting machine

Abstract

The invention discloses a discharging device and discharging method of a suspended centrifugal casting machine. The suspended centrifugal casting machine is involved, and comprises a push rod, a hydraulic oil cylinder for driving the push rod to reciprocate and a control device for controlling the working of the hydraulic oil cylinder; a limiting mechanism for controlling advancing and retreating travels of the push rod and a workpiece sensing device are further arranged on the suspended centrifugal casting machine; the limiting mechanism and the workpiece sensing device are electrically connected with the control device, respectively, and transmit working signals for starting and stopping the hydraulic oil cylinder to the control device. The suspended centrifugal casting machine is reasonable in design, exquisite in structure, safe and reliable and convenient to operate; the hydraulic oil cylinder is controlled through a stopping signal so that a pushing distance of the push rod is controlled; the problem that a small-diameter barrel ring is ejected to burn the working personnel under a great ejection force is avoided, and the service life of a shaft can be greatly prolonged through travel control and the replacement frequency of the shaft is reduced; as a result, the double effects of safe production and economic benefit increase are achieved.

Description

technical field [0001] The invention relates to a discharge device and a discharge method, in particular to a discharge device and a discharge method of a suspended centrifugal glue injection machine. Background technique [0002] At present, the centrifugal casting machine is mainly used to produce cylindrical piston rings of various diameters, the diameter size is from 200mm-900mm, the height is 200mm-500mm, and the casting quality is from 20kg-150kg. [0003] In order to produce large-diameter cylinder rings, hydraulic cylinders are used as power for the ejection of the unloading parts, and the jacking force is large. The rated ejection force of the machine is 40000N. The force is so strong that the operator has no time to clamp the cylinder ring with a special clamp and drag it out slowly. Therefore, the cylinder ring is easy to pop out of the centrifugal casting machine and burn the operator. There are many potential safety hazards and the degree of automation is low. ...

Problems solved by technology

[0003] In order to produce large-diameter cylinder rings, hydraulic cylinders are used as power for the ejection of the unloading parts, and the jacking force is large. The rated ejection force of the machine is 40000N. The force is so strong that the operator has no time to clamp the cylinder ring with a special clamp and drag it out slowly. Therefore, the cylinder ring is easy to pop out of the centrifugal casting machine and burn the operator. There are many potential safety hazards and the degree of automation is low.

[0004] And because the thrust of the push rod is relatively large, when the cylinder ring encounters the resistance of the baffle during the pushing out process of the cylinder ring, it is very easy to bend the transmission shaft. At this time, the shaft needs to be replaced again, which not only causes economic losses, but also increases The production cost of the enterprise, frequent shaft replacement will also reduce the processing efficiency of the entire equipment

[0005] Furthermore, since the quality of castings is generally between 20 kg and 150 kg, and the weight is large, manual clamping with special fixtures is labor-intensive, low-efficiency, and requires high physical endurance of the staff, which is difficult for ordinary workers to perform.
