Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forming machines without pattern casting face issues with machining errors due to multiple positioning requirements for multi-side processing and waste sand contamination, which affects production efficiency and tool service life.
Innovation Solution
A forming machine with a multi-axis motion system, a cutting system, and a turnover mechanism that allows for multi-angle machining of sand billets without demounting, combined with a sealed cavity and dust cover to prevent sand contamination, enhancing precision and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sand billet is turned over for several times to achieve multi-side machining, then multi-side machining capability is improved, but positioning errors accumulate and machining quality deteriorates
Solution Approach 1:
The machine tool is divided into a fixed seat and a turnover mechanism. The turnover mechanism can rotate the sand billet to different positions (front, back, left, right sides) while maintaining a fixed relationship between the billet and the machining system, eliminating positioning errors from repeated setup
Solution Approach 2:
The turnover mechanism provides multi-functional positioning capability, allowing the sand billet to be machined on all four sides (front, back, left, right) without demounting. This single mechanism replaces multiple separate positioning operations, achieving both versatility and precision
2Device complexity
If the three-axis motion system is arranged above the machining working platform, then space utilization is improved, but sand grains enter the motion system causing contamination and reduced service life
Solution Approach 1:
Instead of placing the motion system above the working platform (conventional arrangement), the patent inverts the arrangement by placing the three-axis motion system below the machining working platform. This inversion prevents sand grains generated during machining from entering the motion system, eliminating contamination while maintaining compact space utilization

AI summary
The disclosure provides a forming machine without pattern casting, including: a multi-axis motion system; a cutting system, connected with the multi-axis motion system; a driving system, driving the multi-axis motion system to move; and a machining base, wherein the machining base includes a fixing seat and a turnover mechanism, wherein the turnover mechanism is revolvably connected with the fixing seat. Since the forming machine without pattern casting of the disclosure adopts a tilting type and needs no working platform, most of the waste sand grains generated from cutting fall freely into the shakeout groove arranged below the fixing seat, and will not fly into the multi-axis motion system, and will not cause stop failure; thus the precision and service life of the forming machine without pattern casting are improved. Meanwhile, the adoption of turnover mechanism realizes double-side or multi-side machining of sand billet, and thus well solves the problem of error caused by multiple times of positioning if the sand billet needs multi-side machining in conventional art.
