The frame gantry type deep drawing hydraulic press machine is applicable to the alignment, assembly, alignment, stretching, rolling, bending, stamping, etc. of Machine element. One machine can realize various functions, which can be used to modify deformed workpieces, dismantle cylindrical tapered bearings, restrain and install various fasteners. Let’s learn about the characteristics of the lower frame gantry type deep drawing hydraulic press machine.
Characteristics of frame gantry type deep drawing hydraulic press machine:
1. The biggest advantage of frame gantry type deep drawing hydraulic press machine is its good rigidity. The frame gantry type deep drawing hydraulic press machine directly welds the upper and lower beams and pillars, thus omitting the threaded connection of traditional gantry type deep drawing hydraulic press machinees and avoiding the disadvantage of gantry type deep drawing hydraulic press machine nuts loosening under long-term loads. On the other hand, designs typically use smaller forces to prevent deformation of the main body, thereby increasing the stiffness of the frame.
In the unit frame structure of the frame gantry type deep drawing hydraulic press machine, when the working load increases, the deformation of the frame is small. In addition, when the movable beam is subjected to eccentric load, the lateral thrust generated by the deflection of the movable beam is supported by the column, and the steering tie rod will not bend. The horizontal size of the pillar is large and there are many box structures, so it has good bending resistance and rigidity.
2. The guiding accuracy of the frame gantry type deep drawing hydraulic press machine is very high. The movement of the movable beam is guided by a flat adjustable guide rail installed on the frame, which can adjust the clearance, thus greatly increasing the resistance to lateral thrust. This column has good bending resistance. Therefore, when the frame gantry type deep drawing hydraulic press machine is subjected to lateral thrust, the bending deformation is small and the guiding accuracy is high.
3. Frame gantry type deep drawing hydraulic press machinees are highly fatigue resistant, mainly referring to combination frame gantry type deep drawing hydraulic press machinees. In the structure of a four column gantry type deep drawing hydraulic press machine, the cylinder is subjected to a combination of tensile and bending forces under eccentric load, and is in a complex stress state, with a stress cycle of pulsation. In the unit frame structure, the original columns are replaced by tensile bolts made of high-strength materials to withstand tensile forces, while hollow columns are used to withstand bending moments and axial pressures, resulting in a significant improvement in the stress situation of the columns. Improved fatigue resistance of the frame.
4. Adopting advanced welding technology, with large space for up and down movement and easy suppression of workpieces, pre-set working pressure, equipped with electronic digital ton display, hydraulic system heat dissipation device, independent movable pump station, return hydraulic control unloading, optional protective net
When adjusting the gantry type deep drawing hydraulic press machine, the first step is to adjust the parallelism between the slider and the workbench by adjusting the upper beam nut, and pay attention to the foundation of mechanical accuracy adjustment. In the pressurized state (holding pressure), the live village and the components connected to the movable beam are tightened and integrated, while also tightening the cylinder body and the components connected to the upper beam. Then, try to tighten the locking nut under the workbench as much as possible, so that precision adjustment can be carried out without load.
In precision adjustment, due to the fact that the lower surface of the movable beam is perpendicular to the piston rod, the lower surface of the movable beam becomes flat and deviates from the parallelism of the table, which can reflect that the piston centerline is perpendicular to the table. Therefore, the movable beam can be fixed in the middle position and the deviation of parallelism can be measured in advance. After the parallelism inspection and adjustment, it is necessary to check whether the verticality of the movable beam meets the requirements.
A situation where the requirements are not met. The adjustment method is the same as adjusting the parallelism until the requirements are met. Similarly, when there is a contradiction between the accuracy of verticality adjustment and parallelism, and the value exceeds the specified value, assembly quality inspection and individual quality inspection of components such as movable beams should be carried out.
There are two types of frame gantry type deep drawing hydraulic press machine: gantry type deep drawing hydraulic press machine and gantry type deep drawing hydraulic press machine. The Total pressure generated by the press is relatively large and is usually used for forging and stamping. The forging gantry type deep drawing hydraulic press machine is divided into die forging gantry type deep drawing hydraulic press machine and free forging gantry type deep drawing hydraulic press machine. The die forging gantry type deep drawing hydraulic press machine uses dies, but the free forging gantry type deep drawing hydraulic press machine does not use dies.
