背景技术Background technique
压力机是一种通过对坯料施加压力，使坯料变形达到预期设计要求的压力加工设备，可实现锻压、冲压、冷挤、拉深等多种成形工艺，其通用性强，广泛应用在各行各业。根据工作原理，压力机可以分为液压机和机械压力机两种，普通液压机由油泵供油，工作阶段液压油一直处于高压状态，由于空行程阶段无负载，高压油液将通过液压阀和液压油路卸荷，压力损耗基本上全部转化为热量，致使液压油温度升高，导致油液泄漏和大量能量损耗。相较于液压机，机械压力机不存在空行程浪费能量这一问题，且空行程速度一般较快，但是机械压力机在设计制造后其冲压曲线一般是固定的，对于某些对冲压曲线有特殊要求的工艺，机械压力机往往容易出现褶皱和裂纹等问题，且机械压力机的设计和制造成本较高，受机械结构的限制机械压力机的设计吨位一般不能做到很大。The press is a pressure processing equipment that deforms the blank to meet the expected design requirements by applying pressure to the blank. It can realize various forming processes such as forging, stamping, cold extrusion, and deep drawing. It has strong versatility and is widely used in various industries. Industry. According to the working principle, presses can be divided into hydraulic presses and mechanical presses. Ordinary hydraulic presses are supplied with oil by an oil pump. The hydraulic oil is always in a high-pressure state during the working stage. Since there is no load in the idle stroke stage, the high-pressure oil will pass through the hydraulic valve and the hydraulic oil. When the road is unloaded, the pressure loss is basically converted into heat, which causes the temperature of the hydraulic oil to rise, resulting in oil leakage and a large amount of energy loss. Compared with the hydraulic press, the mechanical press does not have the problem of wasting energy in the idle stroke, and the idle stroke speed is generally faster, but the stamping curve of the mechanical press is generally fixed after the design and manufacture, and for some stamping curves there are special Due to the required process, mechanical presses are often prone to problems such as wrinkles and cracks, and the design and manufacturing costs of mechanical presses are relatively high. Due to the limitation of mechanical structures, the design tonnage of mechanical presses generally cannot be large.
随着现代制造技术的不断发展，要求压力机具有高的控制精度和响应速度，同时保留大负载特性，传统的机械压力机和液压机由于存在上述问题，使其应用受到一定限制。With the continuous development of modern manufacturing technology, presses are required to have high control precision and response speed while retaining large load characteristics. Due to the above problems, traditional mechanical presses and hydraulic presses have limited their application.

参照图4，与外滚柱508啮合的转子509内螺纹和内缸体502外螺纹均为多头螺纹且螺纹牙型为90°三角形螺牙（α角），外滚柱508外螺纹为单头螺纹且为圆弧形螺牙，三者螺纹螺旋方向相同；与内滚柱526啮合的小活塞525内螺纹和丝杠527外螺纹均为多头螺纹且螺纹牙型为三角形螺牙，内滚柱526外螺纹为单头螺纹且为圆弧形螺牙，三者螺纹螺旋方向相同；假定外滚柱508或内滚柱526公称直径为dR，与之啮合的内螺纹和外螺纹分别为dN和dW，则存在关系式且必须为整数，外滚柱508或内滚柱526螺牙圆弧半径为Referring to Figure 4, the internal thread of the rotor 509 and the external thread of the inner cylinder 502 engaged with the external roller 508 are both multi-start threads and the thread profile is a 90° triangular thread (angle α), and the external thread of the external roller 508 is single-start The threads are arc-shaped threads, and the helical direction of the three threads is the same; the internal thread of the small piston 525 and the external thread of the lead screw 527 meshed with the inner roller 526 are multi-start threads and the thread profile is a triangular thread, and the inner roller The 526 external thread is a single-start thread and an arc-shaped thread, and the three threads have the same helical direction; assuming that the nominal diameter of the external roller 508 or the internal roller 526 is dR , the internal and external threads engaged with it are respectively dN and dW , then there is a relation and Must be an integer, the radius of the thread arc of the outer roller 508 or inner roller 526 is
本发明的工作原理为：空行程阶段，转子509在动子绕组507的电磁力作用下开始转动，带动外滚柱508作行星转动，由于转子509和外滚柱508轴向自由度被限制，活塞531与滑块3相连周向不能转动，又有防转平键503的存在，内缸体502周向自由度被限制，内缸体502只能上下运动，该运动阶段无负载，设计电机时采用小功率。工作行程阶段，交流伺服电机516通过行星减速装置和行星滚柱丝杠装置，驱动小活塞525向下运动，由于有第一防转平键511的限制作用，小活塞525只能上下运动而不能转动，小活塞525底面积要小于大活塞531上表面积，小活塞525上的力经过增压腔A内的油液后传递到大活塞531后得到了放大，放大倍数为大活塞531上表面与小活塞530下表面面积之比，大活塞531活塞杆推动滑块3向下运动，完成公称压力行程。返程阶段，交流伺服电机516反转，带动小活塞525向上运动，增压腔A内油液压力降低，回程腔内的弹簧532处于压缩状态推动大活塞531向上运动，空行程装置内的转子509反转带动内缸体502向上运动，回到初始位置。The working principle of the present invention is: during the idle stroke stage, the rotor 509 starts to rotate under the action of the electromagnetic force of the mover winding 507, and drives the outer roller 508 to perform planetary rotation. Since the axial freedom of the rotor 509 and the outer roller 508 is limited, The piston 531 is connected to the slider 3 and cannot rotate in the circumferential direction, and there is an anti-rotation flat key 503. The degree of freedom in the circumferential direction of the inner cylinder 502 is limited, and the inner cylinder 502 can only move up and down. There is no load in this movement stage, and the design of the motor When using low power. In the working stroke stage, the AC servo motor 516 drives the small piston 525 to move downward through the planetary reduction device and the planetary roller screw device. Due to the restriction of the first anti-rotation flat key 511, the small piston 525 can only move up and down but not Rotate, the bottom area of the small piston 525 is smaller than the upper surface area of the large piston 531, and the force on the small piston 525 is amplified after passing through the oil in the booster chamber A to the large piston 531. The magnification is the upper surface of the large piston 531 and The ratio of the lower surface area of the small piston 530 to the piston rod of the large piston 531 pushes the slide block 3 to move downward to complete the nominal pressure stroke. In the return stage, the AC servo motor 516 reverses, driving the small piston 525 to move upward, the oil pressure in the pressurized chamber A decreases, the spring 532 in the return chamber is in a compressed state and pushes the large piston 531 to move upward, and the rotor 509 in the idle stroke device The reversal drives the inner cylinder body 502 to move upwards and return to the initial position.
