刀桿手動壓力機設(shè)計
摘要: 本課題是刀桿手動壓力機的設(shè)計，針對機械裝置工作條件，設(shè)計符合實際工作要求的壓力機。壓力機的設(shè)計包括齒輪軸、齒條、箱體的設(shè)計和一些零部件的選用校核等。在設(shè)計過程中，根據(jù)任務(wù)書提供的壓力機的長度、寬度、高度、行程等要求，完成壓力機的總體設(shè)計。對壓力機進(jìn)行受力分析，完成齒輪的設(shè)計。由于壓力機的機身結(jié)構(gòu)緊湊，齒輪與軸連成一體，做成齒輪軸結(jié)構(gòu)。在齒輪軸設(shè)計時候，完成選用軸承、擬定軸上的零件的裝配方案、校核軸的強度要求等工作。完成齒輪軸結(jié)構(gòu)的的設(shè)計后，就可以進(jìn)一步確定與其嚙合的齒條的尺寸，并設(shè)計齒條的工藝規(guī)程。齒條的工藝規(guī)程設(shè)計有兩種方案，比較兩種方案的優(yōu)劣，選擇合適的一種。軸承對壓力機的工作發(fā)揮著重要的作用，應(yīng)該校核其強度，設(shè)計其密封裝置等。在以上各項工作完成后，可以設(shè)計壓力機機身（箱體）的設(shè)計和軸承端蓋的設(shè)計。最后，還應(yīng)進(jìn)行成本校核，成本核算的實質(zhì)是一種數(shù)據(jù)信息處理加工的轉(zhuǎn)換過程，即將日常已發(fā)生的各種資金的耗費，按一定方法和程序，按照已經(jīng)確定的成本核算對象或使用范圍進(jìn)行費用的匯集和分配的過程。成本校核的目的是為了在滿足機械工作要求和加工精度的基礎(chǔ)上，設(shè)計出最經(jīng)濟(jì)廉價產(chǎn)品。

The design of Arbor Manual Press
Abstract:Holders of this issue is to manually press-style design, working conditions for mechanical devices, were designed to press the actual job requirements. The design of presses, including gear, rack, cabinet design and a number of components, such as the choice of checking. During the design process, according to mandate the provision of the Press book length, width, height, stroke and other requirements, the completion of the design press. Stress Analysis of Press to complete the design of gear. Completion of the structure of the design of gear, you can further complete the rack design, and design Process rack. Process design of the rack, there are two programs: one-piece small batch production and mass production. According to the actual situation of the workshop process to choose the appropriate line. As the press of the fuselage structure, connecting gear with the shaft, gear shaft into the structure. At the completion of the design of gear based on the complete selection of bearings, shaft to complete the design, preparation of parts of the assembly axis program, check-axis intensity of the work requirements. Bearing on the work of press plays an important role, we should check its strength, the design of the sealing devices. In the above work is completed, press frame can be designed (box) cover the design and the design of bearings. Finally, the cost of checking should be carried out, the real cost of information processing is a data processing conversion process. The purpose of the cost of checking is to meet the mechanical requirements and processing accuracy, based on the most economical to design low-cost products.
