Description
Technical Field
The utility model belongs to the technical field of the mould technique of separating, especially, card mould release mechanism.
Background
In the forging process, materials made of different materials can generate different deformation resistances, and the reasons for influencing the deformation resistances are many, such as material temperature, die lubrication, the projection area of a forging piece, actual capacity occurrence points and the like. If the operation is not proper or the estimation is wrong, the forging machine energy cannot meet the forming energy requirement, so that the forging machine is stopped due to the loss of the forging machine energy, and the sliding block cannot return to the top dead center after the motor is restarted, which is called as die clamping. In the past, the situation of mold clamping can only be eliminated by negatively cutting and damaging the mold, and the following defects of the cutting mold are as follows:
(1) the cutting of the die needs oxyacetylene, and the large die needs more consumption.
(2) The die after cutting can no longer be used.
(3) Time consumption and delayed production.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
The present embodiment will be described in detail with reference to fig. 1 to 3.
Reasonable gaps exist in all mechanisms in the forging machine, so that the condition that the service life of parts is influenced due to interference caused by temperature rise and load in the production process is avoided; the phenomenon of die clamping is that under the condition of overload of a forging machine, the clearance of a transmission part is eliminated, so that the friction force between parts is larger than the energy of the forging machine, the machine is stopped, and no clearance exists between a sliding block and a connecting rod, so that the die clamping is realized. The design principle of the invention is to generate a quantitative gap in advance, and release the gap when the die clamping condition occurs to allow the connecting mechanism to have enough gap to actuate, but the gap needs to keep a constant state in the production process of the forging machine to avoid poor precision of the forging piece, so that the design uses an oil pressure cylinder and a pneumatic oil pressure pump to reduce the size of the oil pressure cylinder by high pressure, thereby reducing the weight and the space requirement.
The mold clamping release mechanism according to the present embodiment includes a hydraulic cylinder 8 disposed below the adjusting screw 6 in the slide mold height adjusting mechanism, and a hydraulic pump communicated with the hydraulic cylinder 8 through a hydraulic line 9. The adjusting screw 6 used is a spherical adjusting screw. The hydraulic pump is a pneumatic hydraulic pump. The mold clamping release mechanism in the embodiment is driven by oil pressure. The hydraulic cylinder 8 is installed below the spherical adjusting screw 6, and the hydraulic cylinder 8 is fixed to the slider and can be regarded as an integral body with the slider adjusting mechanism. The pneumatic oil pressure pump is fixedly arranged on the frame.
The pneumatic oil pressure pump used in this embodiment includes an electromagnetic valve 10, a pressure relief valve 11, a pressure gauge 12, a pressure switch 13, a circuit board 15, an air control valve 15, an oil inlet foot rest 16, an oil level gauge 17, an air pressure regulating valve 18, a pump 19, and an oil tank 20. One side of the air pressure regulating valve 18 is communicated with the pump 19, and the other side is communicated with the hydraulic pipeline 9 to provide pressure for the hydraulic cylinder 8.
Further, the slider according to the present embodiment includes a slider body 1, a coupling mechanism, and a die height adjusting mechanism. The connecting mechanism comprises a mandrel 3 connected with the slider body 1 and an eccentric shaft 4 connected with the mandrel 3 through a connecting rod 2. The die height adjusting mechanism comprises an eccentric adjusting rod 5, an adjusting screw rod 6 and a worm wheel 7. One end of the eccentric adjusting rod 5 is connected with the mandrel 3, and the other end is connected with the spherical adjusting screw 6. The end of the adjusting screw 6 is connected with the worm wheel 7, the spherical adjusting screw 6 and the worm 7 are in threaded connection, and the height of the sliding block can be adjusted by adjusting the spherical adjusting screw 6.
The oil pressure system loop used in the embodiment adopts a normally open design, can avoid power failure and voltage loss, and is 3-4kg/cm2The hydraulic pressure can be ensured to be stable under the action environment of the air pressure. Forging machineUnder the condition of power failure, the continuous voltage state can still be ensured.
And 3-4kg/cm without high pressure gas source2The pressure of the hydraulic oil is increased to 200 and 250cm by a pump2Thus, the functional requirements can be met. In addition, in the embodiment, the clamping and releasing mechanism and the oil pressure system parts are modularized, so that the parts are easy to replace, and the maintenance time is saved.
In a severe mold clamping situation, there is a situation that after the pressure of the oil pressure cylinder 8 is released, there is still no sufficient clearance action, and at this time, an auxiliary mold clamping release scheme needs to be used, as shown in fig. 3, three solutions of the auxiliary mold clamping release scheme are provided. The auxiliary solution for releasing the clamping die is to use a jack 22, and one end of the jack 22 is in contact with the flange 21 on the connecting rod 2, and the other end is in contact with the adjusting screw 6. The jack 22 drives the connecting rod to move, and a gap can be generated. The jack 22 can be connected to an electric hydraulic pump A or a manual hydraulic pump B for operating the jack.
The specific operation procedure of the auxiliary method for releasing the clamping die is as follows:
1. the nut of the air pressure regulating valve 18 is loosened to release the air pressure.
2. The hydraulic line 9 is disconnected to allow the grease in the hydraulic cylinder 8 to flow out.
3. The two ends of the operating jack 22 respectively support the flange 21 on the connecting rod 2 and the top end of the adjusting screw 6, so that the operating jack 22 is pressed by the force to enable the adjusting screw 6 to descend by about 15mm to drive the connecting rod 2, the sliding block is lifted, and the mold clamping phenomenon is separated.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts.
