Crafting a Screwdriver in Creo: A Step-by-Step Guide

圖片
Creating a screwdriver in Creo can be an enriching experience, especially when you use a variety of features to replicate a real-world object. In this tutorial, we'll guide you through the process of designing a screwdriver using Extrude , Extrude (cut) , Revolve (cut) , Swept Blend , Shell , and Pattern functions. Step 1: Start a New Part Go to New > Type = Part > Sub-Type = Solid > Use default template > OK . Step 2: Create the Handle Base Select the FRONT plane , then choose Extrude . Sketch a hexagon : Select Palette , choose a 6-sided hexagon, and click OK to exit the sketch. Set the extrusion Depth to 90 and click OK to create the handle body. Step 3: Trim the Handle with a Revolve Cut Select the TOP plane , then choose Revolve . Sketch the cutting shape as per the reference photo and click OK to exit the sketch. Select the Axis A_1 (created by selecting both TOP and RIGHT planes). Set to remove material and click OK to trim the body. Note that if we s...

生產壓縮彈簧

最近開始操作彈簧機生產壓縮彈簧。根據維基百科，壓縮彈設計用於在壓縮載荷下運行，因此彈簧在施加載荷時會變短。彈簧機主要的部份有送線機，CAM/CNC主機和熱處理設備。線材是不鏽鋼316,直徑0.9-1.0mm。 生產前調機主要的問題有送料機和主機速度不配合：送料過慢會停機，過快的時候會令到線材糾纏。CAM/CNC主機上有送線輪、金屬導向線板、曲線規和模心，配合線材直徑送線。送線輪壓得線材太緊或送線輪和線板有干涉可能會引起送線不暢順，或會導致伺服馬達報錯。由設定主機的曲線規、模心位置和CNC程序輸入x、y、z參數來控制彈簧的外徑、圈數、間距(pitch)和自由長度。CNC編程壓線圈我知道的不多，希望找到相關資料再和大家分享。 彈簧品質控制是生產過程重要的一環。以下是壓縮彈簧關鍵控制參數： 1) 線材直徑 wire diameter 2) 彈簧外徑 spring outer diameter 3) 自由長度 free length 4) 總圈數 total coils 5) 有效圈數 active coils 根據胡克定律(Hooke's law)和JIS標準，彈簧系數(spring constant k)和彈簧行程受上述的參數影響而改變。例子如減少有效圈數，彈簧系數增加、彈簧行程減少。
