三、HT28 油缸帶頂出的四柱油壓機(jī)主要由機(jī)身、液壓系統(tǒng)、電氣控制系統(tǒng)等部分組成，其工作原理如下：
動力傳遞：電機(jī)驅(qū)動油泵運(yùn)轉(zhuǎn)，將液壓油從油箱中吸出并加壓，形成高壓油液。高壓油液通過油管輸送到各個液壓元件，為油壓機(jī)的工作提供動力。
主油缸工作：當(dāng)需要進(jìn)行壓制工作時，電氣控制系統(tǒng)控制相應(yīng)的電磁換向閥動作，使高壓油液進(jìn)入主油缸的無桿腔，推動主油缸的活塞下行，從而帶動滑塊（連接在活塞上）向下運(yùn)動，對放在工作臺上的工件施加壓力，實(shí)現(xiàn)壓制工藝。同時，主油缸有桿腔的油液通過電磁換向閥流回油箱。在壓制過程中，可通過調(diào)節(jié)液壓系統(tǒng)中的溢流閥來控制油液壓力，以滿足不同的壓制力要求。
頂出油缸工作：當(dāng)壓制完成需要頂出工件時，電氣控制系統(tǒng)控制另一組電磁換向閥動作，使高壓油液進(jìn)入頂出油缸的無桿腔，推動頂出油缸的活塞向上運(yùn)動，頂出桿伸出，將工件從模具中頂出。頂出油缸有桿腔的油液則通過電磁換向閥流回油箱。頂出的力度和行程可通過調(diào)節(jié)相應(yīng)的壓力閥和行程開關(guān)來控制。
回程：壓制和頂出完成后，電磁換向閥再次動作，使主油缸和頂出油缸的油路換向。主油缸的有桿腔進(jìn)入高壓油液，推動活塞上行，滑塊回程至初始位置；頂出油缸的有桿腔進(jìn)入高壓油液，使頂出桿縮回至初始位置。此時，油缸無桿腔的油液流回油箱。
保壓與泄壓：在壓制過程中，若需要保持一定的壓力一段時間，液壓系統(tǒng)可通過保壓回路實(shí)現(xiàn)。保壓時，油泵停止供油，由蓄能器或單向閥等元件保持系統(tǒng)壓力。當(dāng)工作完成后，需要對系統(tǒng)進(jìn)行泄壓，以防止在拆卸模具或進(jìn)行其他操作時發(fā)生危險。泄壓過程通過相應(yīng)的泄壓閥來實(shí)現(xiàn)，緩慢釋放系統(tǒng)中的高壓油液，使系統(tǒng)壓力降至安全范圍。
Performance Introduction of the Four-column Hydraulic Press with a Top-out Cylinder of Model HT28
I. Purpose:
This series of hydraulic presses is suitable for the pressing processes of malleable materials, such as stamping, bending, flanging, thin plate stretching, etc. It is also suitable for processes like calibration, press fitting, molding of powder products, as well as the compression molding of non-metallic materials.
II. Features:
The four-column hydraulic press with a top-out cylinder of model HT28 typically has the following performance characteristics:
Solid and Stable Structure: With a four-column structural design and a reasonable cylinder configuration, it can withstand a large working pressure and operate stably and reliably. The fuselage is made of high-quality materials and undergoes strict processing and treatment processes, having good rigidity and strength, which can ensure the accuracy and stability of the equipment during long-term use.
Practical Top-out Function: Equipped with a cylinder top-out device, the top-out force is moderate and can meet various process requirements. The top-out stroke can be adjusted according to the actual processing situation, and the operation is convenient. The top-out action is smooth, and the top-out position and force can be precisely controlled to ensure the processing quality of workpieces and production efficiency.
Efficient Hydraulic System: Adopting an advanced hydraulic system, it is composed of reliable oil pumps, cylinders, and various hydraulic valves, etc. The system has good sealing performance, which can effectively prevent leakage, ensure the cleanliness of the hydraulic oil, and extend the service life of hydraulic components. The pressure and flow rate of the hydraulic system can be adjusted according to process requirements, achieving a fast and stable working cycle and improving production efficiency.
Intelligent Electrical Control: Equipped with an intelligent electrical control system, the operation interface is simple and clear. It can achieve multiple operation modes such as manual and semi-automatic, which is convenient for operators to select according to different processing requirements. The control system has functions of fault diagnosis and alarm, which can timely detect and troubleshoot faults to ensure the normal operation of the equipment.
Good Safety Performance: A variety of safety protection devices are set up, such as emergency stop buttons, upper and lower limit switches, etc., which can effectively prevent unexpected situations during the operation of the equipment, ensuring the personal safety of operators and the normal operation of the equipment. At the same time, complete components such as protective fences and protective covers of the equipment can prevent operators from coming into contact with dangerous parts.
Wide Application Range: It is suitable for various processing processes of metal materials, such as stretching, bending, flanging, calibration, press fitting, etc., and can also be used for the molding processing of non-metallic materials such as plastics and rubbers. Corresponding molds can be equipped according to different process requirements to meet the production needs of different products.
Convenient Maintenance: The structural design of the equipment is convenient for maintenance. The installation positions of each component are reasonable, making it easy to inspect and repair. The components of the hydraulic system are compactly arranged, which is convenient for replacement and adjustment. At the same time, the lubrication system of the equipment can be lubricated automatically or manually to reduce the wear of components and extend the service life of the equipment.
This series of hydraulic presses has two types of electrical control systems, namely relay control and PLC control, and has three operation modes: adjustment, manual, and semi-automatic. It can achieve two process modes: pressing and customized. During fixed-pressure molding, there is an automatic return action. A top-out device is installed in the middle of the worktable. In addition to ejecting products, it can be used as a hydraulic cushion for the molding process of reverse stretching parts. The working pressure and stroke can be adjusted within the specified range according to process requirements.
III. The four-column hydraulic press with a top-out cylinder of model HT28 is mainly composed of parts such as the fuselage, hydraulic system, and electrical control system, and its working principle is as follows:
Power Transmission: The motor drives the oil pump to operate, sucking out and pressurizing the hydraulic oil from the oil tank to form high-pressure oil. The high-pressure oil is transported to each hydraulic component through the oil pipe, providing power for the operation of the hydraulic press.
Operation of the Main Cylinder: When a pressing operation is required, the electrical control system controls the corresponding electromagnetic directional valve to act, allowing the high-pressure oil to enter the rodless cavity of the main cylinder, pushing the piston of the main cylinder to move downward, thereby driving the slider (connected to the piston) to move downward and apply pressure to the workpiece placed on the worktable to achieve the pressing process. At the same time, the oil in the rod chamber of the main cylinder flows back to the oil tank through the electromagnetic directional valve. During the pressing process, the oil pressure can be controlled by adjusting the relief valve in the hydraulic system to meet different pressing force requirements.
Operation of the Top-out Cylinder: When the workpiece needs to be ejected after the pressing is completed, the electrical control system controls another set of electromagnetic directional valves to act, allowing the high-pressure oil to enter the rodless cavity of the top-out cylinder, pushing the piston of the top-out cylinder to move upward, and the ejector rod extends to eject the workpiece from the mold. The oil in the rod chamber of the top-out cylinder flows back to the oil tank through the electromagnetic directional valve. The top-out force and stroke can be controlled by adjusting the corresponding pressure valve and travel switch.
Return Stroke: After the pressing and top-out are completed, the electromagnetic directional valve acts again to reverse the oil circuit of the main cylinder and the top-out cylinder. The high-pressure oil enters the rod chamber of the main cylinder, pushing the piston to move upward, and the slider returns to the initial position; the high-pressure oil enters the rod chamber of the top-out cylinder, making the ejector rod retract to the initial position. At this time, the oil in the rodless cavity of the cylinder flows back to the oil tank.
Pressure Maintaining and Pressure Relief: During the pressing process, if it is necessary to maintain a certain pressure for a period of time, the hydraulic system can achieve this through the pressure maintaining circuit. During pressure maintaining, the oil pump stops supplying oil, and components such as the accumulator or check valve maintain the system pressure. After the work is completed, the system needs to be depressurized to prevent danger during mold disassembly or other operations. The pressure relief process is achieved through the corresponding pressure relief valve, slowly releasing the high-pressure oil in the system to reduce the system pressure to a safe range。
