Background
The movable beam of the horizontal carbon electrode extrusion equipment is a core transmission component of the extrusion force. In the prior art, a movable cross beam of horizontal carbon electrode extrusion equipment adopts a three-cylinder coplanar movable cross beam, three working cylinders of the horizontal carbon electrode extrusion equipment are all connected with the movable cross beam, and acting force acts on the movable cross beam when the three working cylinders work. The defects of the prior art are as follows:
1. the stress condition of the movable beam is complex, and the bending and the deformation of the activity content are easily caused;
2. in order to prevent the bending and deformation of the movable content, the rigidity and the strength of the movable cross beam need to be increased, so that the movable cross beam has a huge appearance and a heavy whole machine weight, and the use requirement cannot be well met.
Disclosure of Invention
The invention aims to provide a three-cylinder direct-acting movable cross beam, which overcomes the defects of the prior art.
The technical scheme of the invention is as follows: a three-cylinder direct-acting movable cross beam comprises a movable cross beam, two auxiliary hydraulic cylinders, a main hydraulic cylinder and an extrusion plunger, wherein the rear end part of the extrusion plunger is fixedly connected with the middle part of the movable cross beam, and the two auxiliary hydraulic cylinders are respectively fixedly connected with the movable cross beam on two sides of the extrusion plunger; the method is characterized in that: the end face of the extrusion plunger protrudes out of the rear part of the movable cross beam by more than 0.5mm at the joint of the rear end part of the extrusion plunger and the movable cross beam; the main hydraulic cylinder is connected with the movable cross beam through a main cylinder flange, the main cylinder flange is a Z-shaped ring with a cross section, the upper transverse edge of the Z-shaped ring is attached to the outer circle of a piston of the main hydraulic cylinder, the front surface of the vertical wall of the Z-shaped ring is attached to the end surface of the extrusion plunger, the rear surface of the vertical wall of the Z-shaped ring is attached to the end surface of the piston of the main hydraulic cylinder, a gap of more than 0.5mm exists between the front surface of the vertical wall of the Z-shaped ring and the rear surface of the movable cross beam, the lower transverse edge of the Z-shaped ring is attached to the inner circular surface of the extrusion plunger, the movable cross beam connecting bolt penetrates through the upper transverse edge of the Z-shaped ring to connect the main cylinder flange with the movable cross beam, and the main hydraulic cylinder connecting bolt penetrates through the Z-shaped.
The invention relates to a three-cylinder direct-acting movable cross beam, which is characterized in that: the movable cross beam connecting bolts are more than three and are uniformly arranged along the circumference of the flange ring of the main cylinder, and the main hydraulic cylinder connecting bolts are more than three and are uniformly arranged along the circumference of the flange ring of the main cylinder.
The principle of the three-bar direct-acting movable cross beam is that the end face of the extrusion plunger protrudes out of the rear face of the movable cross beam by more than 0.5mm, the main hydraulic cylinder is connected with the movable cross beam through the main cylinder flange, the front face of the main cylinder flange is attached to the end face of the extrusion plunger, and a gap of more than 0.5mm is reserved between the front face of the main cylinder flange and the rear face of the movable cross beam.
When the hydraulic press works, the main hydraulic cylinder and the auxiliary hydraulic cylinder operate simultaneously to push the movable cross beam and the extrusion plunger to move forwards simultaneously. Because the front of the main cylinder flange connected with the movable cross beam and the main hydraulic cylinder is only connected with the end face of the extrusion plunger, and a gap of more than 0.5mm is reserved between the front of the main cylinder flange and the movable cross beam, the pressure of the main hydraulic cylinder only acts on the extrusion plunger and does not act on the movable cross beam, and the stress condition of the movable cross beam is improved. When retreating, the auxiliary hydraulic cylinder drives the movable cross beam to retreat, and the structure is stable.
The stress condition of the three-cylinder coplanar movable beam in the prior art and the stress condition of the three-cylinder direct-acting movable beam are analyzed as follows: setting a thrust of an auxiliary hydraulic cylinder to f1Thrust of the two sub-cylinders is 2f1The driving force of the main hydraulic cylinder is F1The counter-force of the squeezing plunger is F2. The stress condition of the three-cylinder coplanar movable beam in the prior art is as follows: the movable cross beam bears the whole thrust F of the main hydraulic cylinder1Thrust 2f of two auxiliary hydraulic cylinders1And a counter force F of the squeezing plunger2The stress relation is as follows:
F2＝2f1+F1
the stress condition of the three-bar direct-acting movable beam is as follows: thrust 2f of two sub-cylinders1ExtrudingCounter-acting force F of plunger3The stress relation of the three-bar direct-acting movable beam is as follows:
F3＝2f1
from the stress analysis, the stress of the three-cylinder direct-acting movable beam is greatly reduced compared with the stress of the three-cylinder coplanar movable beam in the prior art.
The invention has the beneficial effects that:
1. effectively reduce movable beam's atress, prevent movable beam conquassation and bending deformation.
2. The movable cross beam has smaller load, and the weight of the movable cross beam is reduced, so that the overall weight of the equipment is reduced, and the energy consumption of the equipment during working is reduced.
3. The hydraulic press can be widely applied to hydraulic presses with large stress on the movable cross beam.
