Description
技术领域technical field
本实用新型涉及压力设备，更具体地说，涉及一种液压压力机。The utility model relates to pressure equipment, in particular to a hydraulic press.
背景技术Background technique
根据产生压力的方式，压力机可以分为以下两类：采用液体传递压力的被称为液压压力机，采用机械传递压力的被称为机械压力机。液压压力机与机械压力机相比，不仅结构不同，而且很多技术问题也不同。According to the method of generating pressure, presses can be divided into the following two categories: those that use liquid to transmit pressure are called hydraulic presses, and those that use mechanical transmission of pressure are called mechanical presses. Compared with mechanical presses, hydraulic presses not only have different structures, but also have different technical problems.
液压压力机的优点是：行程较长、压力可调节、白身结构简单且容易制造、加工速度稳定、不会产生超负荷等。液压压力机由于其众多的优点，是一种很好的成形设备，特别是当液压压力机系统具有对压力、行程速度单独调整的功能后，不仅能够实现对复杂工件以及不对称工件的加工，而且还很适合长行程、难成形及高强度材料的加工，并且加工的废品率极低。因此，液压压力机已成为压力加工领域重要的研究和发展方向。但是，从液压压力机结构来看，国内外液压压力机的基本结构相似，主要由主缸、横梁、滑块、立柱、底座和工作台组成，该种结构的缺点是：结构单一、不能实现增力、不利于压力机的大型化。如何能设计出符合使用性能要求的优越的结构对于液压压力机而言，一直是一个富有挑战性的命题。The advantages of hydraulic presses are: long stroke, adjustable pressure, simple body structure and easy manufacturing, stable processing speed, and no overload. Due to its many advantages, the hydraulic press is a good forming equipment, especially when the hydraulic press system has the function of independently adjusting the pressure and stroke speed, it can not only realize the processing of complex workpieces and asymmetrical workpieces, It is also very suitable for the processing of long-stroke, difficult-to-form and high-strength materials, and the reject rate of processing is extremely low. Therefore, the hydraulic press has become an important research and development direction in the field of pressure processing. However, from the perspective of hydraulic press structure, the basic structure of hydraulic presses at home and abroad is similar, mainly composed of main cylinder, beam, slider, column, base and workbench. Increased force is not conducive to the enlargement of the press. How to design a superior structure that meets the performance requirements has always been a challenging proposition for hydraulic presses.
