設(shè)計(jì)總說明
  
本文主要介紹的用于鍛壓機(jī)床上工件加熱機(jī)械裝置的原理、結(jié)構(gòu)及其使用性能。整體設(shè)計(jì)結(jié)構(gòu)采用模塊化設(shè)計(jì)，將加熱機(jī)械裝置分為減速傳動機(jī)構(gòu)、轉(zhuǎn)動機(jī)構(gòu)、反靠定位機(jī)構(gòu)、加熱裝置、支架等。

    本文對加熱機(jī)械裝置進(jìn)行總體方案設(shè)計(jì)，得出如下重點(diǎn)部件的設(shè)計(jì)方案。減速傳動機(jī)構(gòu)采用蝸輪蝸桿減速器加上鏈條傳動；反靠定位機(jī)構(gòu)使用彈簧銷及錐孔定位；間歇傳動使用時(shí)間繼電器控制；加熱裝置采用火焰加熱。采用圓盤作為轉(zhuǎn)動機(jī)構(gòu)使整體設(shè)計(jì)結(jié)構(gòu)緊湊。

     該機(jī)構(gòu)對轉(zhuǎn)動速度要求較高，不僅要求低速傳動，而且要求間歇停留時(shí)間。為解決這一問題，使用調(diào)速電機(jī)和蝸輪蝸桿聯(lián)合使用，并采用時(shí)間繼電器來完成間歇停留的任務(wù)。本文對減速器進(jìn)行了詳細(xì)設(shè)計(jì)計(jì)算，并對轉(zhuǎn)動機(jī)構(gòu)、定位機(jī)構(gòu)、支架進(jìn)行了詳細(xì)結(jié)構(gòu)設(shè)計(jì)。

     本設(shè)計(jì)以自動化裝置設(shè)計(jì)為標(biāo)準(zhǔn)，裝置精度要求較低，采用普通加工工藝，以較低成本完成產(chǎn)品制造為原則，作出該裝置設(shè)計(jì)說明書。

關(guān)鍵詞：加熱機(jī)械裝置、反靠定位、時(shí)間繼電器。

DESIGN INSTRUCTION

This paper describes the principle for forging machine tool on the workpiece heating mechanism, structure and performance. The overall design of the structure is modular in design, the heating mechanism is divided into deceleration transmission mechanism, rotation mechanism, anti-rely on the positioning mechanism, heating devices, such as a stent.

       In this paper, the heating mechanism for the overall program design, draw the design of the following key components. Reducer worm gear reducer with chain drive transmission mechanism; anti-rely on the positioning mechanism using a spring pin and taper positioning; intermittent transmission relay control; heating device heated by the flame. Using the disc as a rotating body so that the overall compact design.

      The higher the rotational speed, requires not only the low-speed transmission, and requires intermittent residence time. To solve this problem, use the speed control motor and worm gear used in conjunction with, and the time relay to complete the task of intermittent stay. Detailed design calculations of the reducer, and the rotating body, the positioning mechanism, stents detailed structural design.
 
     Designed to automate device design, device accuracy requirements are lower, the ordinary process, at a lower cost to complete the manufacturing principle to make the design specification of the device.

Keywords: heating mechanism, anti rely on positioning, time relay.
