What is Car door hydraulic press machine?
Doors are an essential part of any vehicle, providing functionality and safety to the driver and passengers. Manufacturing a car door requires a series of steps and processes, one of which involves the use of hydraulic presses. A hydraulic press is a machine that uses hydraulic pressure to apply force to a material. The machine consists of a hydraulic cylinder and a pump to generate the pressure needed to shape the material.
Hydraulic presses can be used to shape a variety of materials, including metal, plastic, and wood. Automobile door bezel compression forming hydraulic press, also known as automobile door panel forming four-column hydraulic press, auto door sheet metal stretching hydraulic press, is a multi-functional three-beam four-column hydraulic press for stretching and forming of metal materials.
The automobile door baffle press forming hydraulic press has a compact structure and adopts advanced high-quality hydraulic electronic components, so it has a series of advantages such as sensitive and reliable action, safe and convenient operation, stable work, low energy consumption, long service life, and durability. car door hydraulic press machine

Understandable Principles Of Hydraulic Press Machine Pressing Car Door :
The machine is based on the dynamic characteristics of advanced cartridge valves and electro-hydraulic proportional control valves in the hydraulic system under high pressure, high speed, and large flow conditions, so that it can better meet the excellent control performance, speed, and stability of the hydraulic machine index. Furthermore, the stamping and forming of automobile door panels are carried out. The shear stamping equipment integrates shearing and stamping operations, which can significantly improve the forming efficiency of automobile door sheet metal parts.
During the stamping process of the automobile door bezel, the plastic deformation of the blank is the result of the internal force or the direct action of the internal force caused by the external force exerted by the mold on the blank. The action mode and magnitude of a certain force correspond to a certain deformation. An automobile door baffle press forming a hydraulic press is a machine that uses hydraulic oil as the working medium to transfer energy to realize various processes.
The high-rigidity and high-precision frame of the machine is welded by steel plates, and after heat treatment, the internal stress of the fuselage is eliminated so that the equipment can work stably for a long time without deformation. It has two electrical control systems: relay control and PLC control. There are adjustment, manual and There are three semi-automatic operation modes, and two process modes of constant pressure and fixed range can be realized. When forming under constant pressure, there is a pressure-holding delay and an automatic return action after pressing. car door hydraulic press machine

The movement process of the main cylinder of the automobile door baffle pressing forming a hydraulic press is relatively complicated. There are two steps before the movement, namely the start of the main cylinder and the rapid decline of the slider. The pressure relief of the upper chamber of the main oil cylinder and the return process of the main oil cylinder.
When the pressure in the upper chamber of the main oil cylinder reaches the required working pressure, the electric contact pressure gauge will send out an electric signal, all the electromagnets will be de-energized, and the two related valves will also be closed accordingly, and the upper chamber of the main oil cylinder will be closed to achieve pressure maintenance.
The valve opens and the pump unloads. The pressure in the upper chamber of the main oil cylinder is released. At this time, the pressure in the upper chamber of the main oil cylinder is already high. The role of the valve is slowly opened, and the upper chamber of the main cylinder realizes pressure relief without impact, ensuring that the stretching hydraulic machine is in a safe working state.
7 Amazing Steps Of Production Process:
Step 1: Design the Doors
The first step in manufacturing a door is designing the door. This involves using computer-aided design (CAD) software to create a 3D model of the door. The design shall consider the safety requirements, structural integrity, and aesthetics of the door.
Step 2: Cut the Sheet of Metal
Once the design is complete, the next step is to cut the sheet metal to the desired size and shape. This is usually done with a CNC laser cutter or plasma cutter.
Step 3: Heat the Material
After the material is cut to the correct size and shape, it is heated in a furnace. The purpose of heating metal is to make it more malleable and easier to work with. The temperature of the furnace will depend on the type of metal used and the desired properties of the final product.
Step 4: Press the door with a hydraulic press
After cutting the sheet metal, the next step is to form the shape of the door. This is where hydraulic presses come in. The sheet metal is placed in a hydraulic press which uses hydraulic pressure to form the sheet into the desired shape.

Step 5: Weld the Doors
Once the metal sheets are formed into the shape of the door, the next step is to weld them together. This is often done using robotic welding machines to ensure precise and strong welds.
Step 6: Grind the Doors
After welding, the door is cleaned, sanded, and painted to give it a smooth and even finish. This is an important step, as it not only improves the appearance of the door but also prevents the door from corroding.
Step 7: Add the Door Assembly
The final step in making the door is to add door components such as window regulators, door handles, and locking mechanisms. These components are usually installed by hand, and their placement is critical to the function of the door.Very uneven.
6 Reliable Tips To Help Ensure Use Safety:
- Always read the manufacturer’s instructions before using the machine.
- Make sure the hydraulic press is in good working condition before use.
- Use the correct mold for the material being used.
- Wear appropriate personal protective equipment, including gloves, eye protection, and hearing protection.
- Be careful when operating the machine and keep your hands and other parts of your body away from moving parts.
- Do not exceed the maximum pressure rating of the machine.
In summary, manufacturing a door using a hydraulic press involves a series of steps, from designing the door to adding the door components. The hydraulic press plays a vital role in the process as it is used to form the sheet metal into the desired shape. By following these steps, automakers can produce high-quality doors that are both secure and aesthetically pleasily. car door hydraulic press machine
