Truck longitudinal beams are the longest stamped parts on a car. The truck's longitudinal beam is almost equal to the longitudinal length of the passenger car. The longitudinal beam material is a high-strength thick steel plate, so the blanking, punching, and bending forming forces are very large. Commonly used ones include 2,000-ton, 3,000-ton, 4,000-ton, and 5,000-ton truck chassis hydraulic presses.
The equipment is equipped with a side-opening movable workbench, a mold quick-change clamping mechanism, a hydraulic protection device, and a lower air cushion. This 4,000-ton truck chassis hydraulic press has a main body with a three-beam and eighteen-column structure, consisting of an upper beam, a sliding beam, a workbench, a column, a lock nut, a guide bush, and a stroke limiter.
Our 4,000-ton truck chassis hydraulic press is mainly used for cold stamping of various large and medium-sized covering parts, stretching, bending, forming, and other processes of thin plates. In order to expａnd the scope of the process, some products can also be punched and blanked (blanking) and other processes. It is generally suitable for the manufacturing process of thin plate parts forming in aviation, auto, tractor, machine tool, instrument, chemical, and other industries.
1) The tie rods and nuts of the auto longitudinal beam and crossbeam stamping forming equipment are made of 45# forged steel.
2) The main cylinder is a piston cylinder. The cylinder body is connected to the upper beam through a flange, and the piston rod is connected to the slider. The surface of the piston rod is quenched and ground to improve its surface accuracy and wear resistance. The oil cylinder is sealed with an imported U-shaped sealing ring, which has reliable sealing and a long service life.
3) All structural parts of the fuselage, such as upper beams, columns, worktables, sliders, lower beams, and other large welded parts, are all made of Q235B all-steel plate welded box structures. All major components need to be annealed after welding to eliminate internal stress.
4) The appearance of the fuselage is smooth with no obvious concave and convex phenomena. The welds are neat and tidy, with no welding slag or welding scars.
1. It has two structural forms: frame type and column type.
2. Multiple hydraulic linkages or integral structures.
3. The hydraulic system adopts a proportional valve, proportional servo valve, or proportional pump control, and the action is sensitive and reliable. High control accuracy.
4. It can realize two molding processes of constant pressure and fixed stroke, and has the function of maintaining pressure and delay, and the delay time is adjustable.
5. The working pressure and stroke can be adjusted within the specified range according to the process requirements, and the operation is easy.
6. Use button centralized control. It has three operation modes: adjustment, manual and semi-automatic.
This series of presses is mainly suitable for the pressing and molding of various auto longitudinal beams, large transmission towers, and similar long parts.
In addition to the multi-cylinder and multi-column structure, truck chassis hydraulic presses can also be designed as a combined frame structure. Generally, it is determined according to the specifications and dimensions of the longitudinal and cross beams of the auto, and the thickness of the plates. Zhengxi is a professional hydraulic press manufacturer that can provide high-quality truck chassis hydraulic presses. If you have any needs, please contact us!
