Description

Technical Field

[0001] This utility model belongs to the field of dual master cylinder technology, and in particular relates to a dual master cylinder multi-layer structure air cushion device. Background Technology

[0002] When processing workpieces using a press, an air cushion structure needs to be installed below the lower die to ensure the blank holder force and unloading force during workpiece stretching. For multi-station presses, since there are multiple stations, an air cushion structure needs to be installed at the first station. However, multi-station presses have limited space for installing the air cushion structure, and the pressure requirements for the air cushion structure are high. Therefore, most multi-station presses cannot currently install a universal air cushion structure and require the use of a hydraulic stretching device. Hydraulic stretching devices are generally expensive, and their complex structures greatly increase maintenance costs, causing difficulties in production. In addition, hydraulic stretching devices have poor stability during operation and are prone to operational errors.

[0003] Utility model patent CN204308009U discloses a dual-main-cylinder multi-layer air cushion device, including a support plate installed at the bottom of a press base. A through hole is provided in the middle of the support plate, and a mounting bracket is provided at the bottom of the support plate. An adjusting screw, corresponding to the through hole, is mounted on the mounting bracket. A motor is mounted on the mounting bracket, and the motor's output shaft is connected to a worm gear mechanism mounted on the mounting bracket. The worm gear mechanism is connected to a vertically arranged adjusting shaft that passes sequentially through the through hole and the adjusting screw. This utility model adopts the above-mentioned solution, with a reasonable structural design. It uses a dual-main-cylinder multi-layer air cushion structure, where the multi-layer air cushion drives the two main shafts to cooperate with the mold for stamping. The air cushion structure is small in size and easy to install. The simultaneous operation of the two main shafts ejects the workpiece, resulting in high ejection force, good stability, and precise operation, bringing convenience to production. At the same time, it significantly reduces maintenance costs and saves money.

[0004] Regarding the aforementioned related technologies, the inventor believes that the following defects exist:

[0005] 1. The above structure lacks the function of detecting the air pressure inside the cylinder during use. Because during the use of the cylinder, the air pressure inside may be abnormal or the airflow may be interrupted due to other factors, which will affect the use of the cylinder.

[0006] Therefore, it is necessary to provide a new dual-master cylinder multi-layer structure air cushion device to solve the above-mentioned technical problems. Utility Model Content

Figure 7 The dual-master cylinder multi-layer structure air cushion device includes: a pressure detection mechanism 101 disposed on the dual master cylinder body 100, the pressure detection mechanism 101 including a fixing ring 1, a mounting ring 111, a fixing bolt 112, a mounting ring 2, a pressure sensor 3, and a sealing ring 4. A through hole is provided on the dual master cylinder body 100, the through hole communicating with a gas flow chamber on the dual master cylinder body 100. The fixing ring 1 is disposed on one outer wall of the dual master cylinder body 100, and the mounting ring 111 is fixedly mounted on the inner ring of the fixing ring 1. The inner ring of the mounting ring 111 is adapted to the through hole. The fixing ring 1 communicates with the dual master cylinder body 100. The mounting ring 2 is fixed by multiple fixing bolts 112. The mounting ring 2 is set on one outer wall of the mounting ring 111. The pressure sensor 3 passes through the inner hole of the mounting ring 2 and the mounting ring 111 and extends through the through hole to the gas flow chamber on the dual main cylinder 100. The inner hole of the mounting ring 2 is provided with a sealing ring 4. The sealing ring 4 passes through the inner hole of the mounting ring 111 and extends into the through hole. The sealing ring 4 is adapted to the pressure sensor 3, the mounting ring 2, the mounting ring 111 and the through hole. The pressure sensor 3 forms a seal with the inner hole of the mounting ring 2 and the mounting ring 111 and the through hole through the sealing ring 4.

[0027] The mounting ring 111 has multiple limiting holes, and the inner wall of the limiting holes has multiple limiting slots. The mounting ring 2 has multiple mounting holes, and the multiple mounting holes correspond one-to-one with the multiple limiting holes.

[0028] The air pressure detection mechanism 101 also includes multiple limiting components, each including a limiting insert 5, multiple limiting blocks 6, and a limiting compression column 7. One end of the limiting insert 5 extends into the mounting hole and is fixedly connected to the mounting hole, while the other end of the limiting insert 5 extends into the limiting hole and is slidably connected to the limiting hole.

[0029] The limiting insert 5 has multiple openings at one end away from the mounting ring 2. Multiple limiting blocks 6 are respectively hinged to the multiple openings. The limiting blocks 6 are adapted to the limiting slots. One end of the limiting extrusion post 7 extends into the limiting insert 5 and is slidably connected to the limiting insert 5. The limiting extrusion post 7 is adapted to the multiple limiting blocks 6.

[0030] A connecting ring 8 is threaded onto the mounting ring 2. A limiting block 9 is rotatably mounted inside the connecting ring 8. The outer wall of the limiting block 9 near the mounting ring 2 has multiple receiving holes, each corresponding to a limiting extrusion post 7. The limiting extrusion post 7 is adapted to the receiving holes. The inner wall of the connecting ring 8 has an internal thread, and the outer wall of the mounting ring 2 has an external thread. The internal thread of the connecting ring 8 engages with the external thread of the mounting ring 2.

[0031] The limiting block 9 has an opening that is compatible with the air pressure sensor 3. The air pressure sensor 3 is connected to the power supply via a connecting wire 10.

[0032] The working principle of the dual-master cylinder multi-layer structure air cushion device provided by this utility model is as follows:

[0033] First step: In use, the fixing ring 1 is installed on the dual main cylinder body 100 by multiple fixing bolts 112. The detection end of the air pressure sensor 3 passes through the inner hole and through hole of the mounting ring 111 and extends into the gas flow chamber on the dual main cylinder body 100. At the same time, the limiting insert 5 passes through the limiting circular hole on the mounting ring 111 (the limiting insert 6 is in the retracted state, such as...). Figure 5Then, the limiting compression column 7 is inserted into the limiting insert 5 and squeezes the multiple limiting inserts 6, causing the limiting inserts 6 to pass through the through and be inserted into the limiting slot. Finally, the connecting ring 8 drives the limiting block 9 to pass through the other end of the air pressure sensor 3, and the other end of the limiting compression column 7 is inserted into the storage shell on the limiting block 9. Then, the connecting ring 8 is rotated so that it is installed on the mounting ring 2 under the action of the thread to squeeze and limit the multiple limiting compression columns 7, ensuring that the limiting compression column 7 is always in a squeezed state, thereby improving the stability of the installation.

[0034] The second step: When it is necessary to disassemble the pressure sensor 3, remove the connecting ring 8 by rotating it, then pull out all the limiting squeezing columns 7, and finally pull the mounting ring 2 away from the fixed ring 1. Without the action of the limiting squeezing columns 7, the limiting slot will allow the limiting insert 6 to pass through the opening for storage, making the structure simple. This not only facilitates the disassembly and assembly of the pressure sensor 3, but also allows the pressure sensor 3 to detect the air pressure in the gas flow chamber within the dual main cylinder 100. This allows for timely understanding of the air pressure inside the cylinder, preventing abnormal air pressure or airflow interruption that could render the cylinder unusable. At the same time, the pressure sensor 3 can be wirelessly connected to an external PLC controller, which can then trigger an alarm and alert the staff to perform maintenance.
