In addition to the advantages of a pure air cushion, the CNC hydraulic pad successfully avoids the above defects and has more operability. The CNC hydraulic pad has a complete hydraulic control system. The system is mainly composed of the following components: hydraulic pump, hydraulic cylinder, control valve pipeline, displacement sensing device, monitoring system and so on. The system widely uses advanced valve groups such as proportional pressure control, proportional direction control, proportional flow control, and a large number of hydraulic components such as logic control valves and some large displacement pumps. The combination of these valve members allows the hydraulic pad to control the actuator through the control valve block to meet the process requirements of buffering and blanking force required to stretch the workpiece. Combine the actuators of the hydraulic pad to analyze the tensile properties of the hydraulic pad. The actuator of the hydraulic pad can be divided into two parts: the top crown and the hydraulic cylinder. A plurality of ejector rods are arranged on the top crown, and the ejector rod acts to press the workpiece. The top crown of the hydraulic cushion and the crown structure of the pure air cushion are basically the same, and will not be described. The hydraulic cylinder under the hydraulic crown is different from the cylinder under the pure air cushion. There are five hydraulic cylinders under the hydraulic crown, four of which are the main piston cylinders, distributed at the four corners of the lower part of the crown, a fast The positioning double acting cylinder is arranged in the middle. The intermediate control cylinder controls the speed of the crown and allows it to stop quickly at any point within the stroke range. Because of the above characteristics, it is possible to control the intermediate cylinder before the slider hits the crown, so that the crown has a downward speed, so that a soft contact is made between the slider and the crown, and the vibration is lowered. To the minimum, the problem of the impact of the pure gas cushion is solved. After the slider is in contact with the crown of the hydraulic pad and continues to run downward, the crown provides a blanking force to the workpiece in the mold. Its blank holder force output is realized by the piston cylinders at the four corners. Its blank holder force can be adjusted not only according to the needs of different workpieces, but also the same kind of workpiece can be used in different stretching stages. Adjusted. The adjustment of the blanking force not only can adjust the entire blanking force, but also the pressure of the four points can be adjusted separately. Through the hydraulic pad, the optimal stretching process parameters can be obtained according to the requirements of the stretching process. After the hydraulic pad runs to the maximum stroke, one form is to return quickly with the slider, and the other form is that the hydraulic pad has a hysteresis when the slider returns, then the return stroke is achieved by the proportional valve to achieve the end damping, thereby Reducing vibration. In the hydraulic cylinder, the response time due to the change of the force is very short, so that the adjustment result of the blanking force is very similar to the double-action stretching press to a certain extent, and a single-action press can be equipped with a numerical control hydraulic pad. To achieve the same stretching effect as a double-action press, this greatly simplifies the structure of the press.

What Gym Equipment should beginners use?
In addition to strength equipment and aerobic equipment, the gym also has some essential fitness accessories. These gym fitness accessories can play a good auxiliary role and meet more exercise needs.
Common fitness equipment accessories include:rubber coated dumbbell,rubber straight and curl barbell,Olympic bar,weight plate,colorful kettlebell,rubber floor,aerobic step,gym ball,medicine ball,yoga mat,battle rope,sandbags,etc.
Accessory exercises, sometimes referred to as secondary exercises, generally follow on from the so-called 'primary' or 'compound' exercises. They often allow you to focus on different muscle groups or hit certain muscle groups in different ways.
Accessory exercises are complementary movements you do in addition to your core activities (for example, the bench press, squat, and deadlift) to accumulate additional training volume, build muscle, improve your performance, and enjoy more varied workouts.
Best equipment for Beginners
If you're really stuck, try programming half a session using free weights, focusing on compound lifts like squats, deadlifts and chest press with dumbbells and kettlebells, followed by some time on your favourite cardio machine, aiming for 10-15 minutes of intervals.
Laijian is a fitness equipment accessory supplier from China, with a complete set of fitness equipment and various functional styles for customers to choose from.Our products are sold in Britain, America, Japan, Italy and South East Asia and well appreciated by their purchasers.
