Forging Die Holder Heater Alignment for Thermal Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forging die holders face inefficiencies in heating and temperature measurement during warm or hot forging, as resistance heaters are positioned far from the dies, leading to slow heat transmission and inaccurate temperature measurement.
Innovation Solution
The forging die holder is designed with heater mounting holes positioned to align with the die's side surfaces, allowing resistance heaters to be placed closer to the dies and reducing the press load on them, while temperature sensors are strategically located for accurate measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resistance heaters are disposed on longitudinal surfaces at positions most distant from the dies, then press load on heaters is reduced, but heat transmission to dies becomes slower and less efficient
Solution Approach 1:
The patent applies local quality by creating different structural zones within the die holder: the longitudinal surfaces far from dies maintain structural integrity and load resistance, while the holder surface near the dies incorporates heater mounting holes for efficient heat transmission. This localized functional differentiation resolves the contradiction between durability and heating efficiency.
Solution Approach 2:
The patent transitions from one-dimensional heater placement (only on longitudinal surfaces) to two-dimensional placement by adding heater mounting holes on the holder surface. This dimensional expansion allows heaters to be positioned both far from dies (for durability) and near dies (for heating efficiency) simultaneously, resolving the contradiction.
2Reliability
If resistance heaters are disposed on longitudinal surfaces far from the dies, then press load is reduced, but preheated temperature measurement becomes inaccurate
Solution Approach 1:
The patent introduces the holder surface as an intermediary zone between the longitudinal surfaces and the dies. Temperature sensors mounted on the holder surface near the dies measure temperature at this intermediate location, providing accurate die temperature data while heaters remain protected on the longitudinal surfaces.
Solution Approach 2:
The patent adds a new measurement dimension by placing temperature sensors on the holder surface rather than only on longitudinal surfaces. This allows temperature measurement near the dies for accuracy while maintaining heater protection at distant locations.
3Productivity
If heater mounting holes are formed at positions opposing the holder surface in aligned relation with die side surfaces, then heating efficiency is improved, but press load on heaters increases
Solution Approach 1:
The patent applies local quality by creating specialized heater mounting zones on the holder surface that are positioned to align with die side surfaces. These localized mounting holes provide direct heat transmission paths while the overall holder structure maintains load distribution to protect heaters from excessive press load.
