Suspended centrifugal pouring machine unloading device and unloading method

Abstract

The invention discloses an unloading device and a material unloading method for a suspended centrifugal pouring machine, including a suspended centrifugal pouring machine. The suspended centrifugal pouring machine includes a push rod, a hydraulic cylinder for driving the push rod to reciprocate, and controlling the operation of the hydraulic cylinder. The control device of the suspension type centrifugal pouring machine is also provided with a limit mechanism and a workpiece sensing device to control the advance and retreat stroke of the push rod. The control device sends a working signal for starting and stopping the hydraulic oil cylinder. The invention is reasonable in design, compact in structure, safe and reliable, and convenient in operation. The stop signal is used to control the hydraulic oil cylinder and then the push rod distance, which avoids the problem that the small-diameter cylinder ring is ejected and scalds the staff when it is ejected with a large ejection force. Moreover, the service life of the shaft can be greatly improved through the stroke control, and the replacement frequency of the shaft can be reduced, thereby realizing the two-in-one effect of safe production and improved economic benefits.

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.
