Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of presses, in particular to a quick release device for hot die forging presses when they get stuck Background Art
[0002] The slider of a hot die forging press is small in size and it is impossible to arrange a hydraulic overload protection device inside. When the press gets stuck (the upper and lower dies of the mold cannot be disengaged), for a hot die forging press with a split combined body structure, the stuck situation can be released by manually loosening the locking nuts of the body, but this is time-consuming and laborious, affecting the production efficiency of customers. It can also be released by cutting the mold, which is faster, but will cause economic losses to customers Summary of the Utility Model
[0003] The purpose of the utility model is to provide a quick release device for hot die forging presses that is simple in structure, easy to operate, quickly unlocks, and works stably, so as to solve the problems in the prior art
[0004] The technical solution of the utility model is: a quick release device for hot die forging presses, the device includes a tension screw, a piston, a plurality of oil cylinders, a split body and a plurality of oil inlets and outlets
[0005] The plurality of oil inlets and outlets are respectively arranged on the plurality of oil cylinders, the oil inlets and outlets are connected to the fuel tank of a pneumatic pump, and a solenoid valve is arranged on the pneumatic pump, and the solenoid valve is controlled by a PLC control device
[0006] The plurality of oil cylinders are arranged outside the tension screw, the piston is connected to the oil cylinder and arranged outside the tension screw, the oil cylinder is arranged on the split body, and the tension screw is arranged inside the split body
[0007] The beneficial effect of the utility model is: by controlling the solenoid valve to be energized by the PLC control device, the locking state of the split body is quickly released, so as to quickly disengage the upper and lower dies and restore the normal production of the press Description of the Drawings
[0008] Figure 1 It is a schematic structural diagram of the utility model
[0009] In the figure, 1 is the tension screw, 2 is the piston, 3 is the oil cylinder, 4 is the split body, and 5 is the oil inlet Detailed Embodiment
[0010] A quick release device for hot die forging presses, the device includes a tension screw 1, a piston 2, a plurality of oil cylinders 3, a split body 4 and a plurality of oil inlets and outlets 5
[0011] The multiple oil inlets and outlets 5 are respectively arranged on multiple oil cylinders 3. The oil inlets and outlets 5 are connected to the oil tank of the pneumatic pump. An electromagnetic valve is arranged on the pneumatic pump, and the electromagnetic valve is controlled by a PLC control device;
[0012] The multiple oil cylinders 3 are arranged outside the tensioning screw 1. The piston 2 is connected to the oil cylinder 3 and arranged outside the tensioning screw 1. The oil cylinder 3 is arranged on the split body 4, and the tensioning screw 1 is arranged inside the split body 4.
[0013] The working principle of the present utility model is as follows: When the press is in normal production, the electromagnetic valve is de-energized, and the pneumatic pump is driven by air. The oil tank of the pneumatic pump feeds oil into the oil inlet and outlet holes 5, and oil pressure is generated between the piston 2 and the oil cylinder 3, thereby locking the tensioning screw 1 and the split body 4. At this time, the pre-tightening force of the body is 1.5 times the nominal force.
[0014] When a die jamming and stalling state occurs, the electromagnetic valve is controlled to be energized through the PLC controller. The oil in the multiple oil cylinders 3 flows into the oil tank of the starting pump from the oil inlet and outlet holes 5. At this time, the oil pressure locking force between the piston 2 and the oil cylinder 3 disappears, the split body 4 and the tensioning screw 1 are loosened, and the die jamming and stalling state is relieved;
[0015] The electromagnetic valve is controlled to be de-energized through the PLC controller. The pneumatic pump is driven by air, and the oil tank of the pneumatic pump feeds oil into the oil inlet and outlet holes 5, and oil pressure is generated between the piston 2 and the oil cylinder 3, thereby locking the tensioning screw 1 and the split body 4 again.
