Pressing Machine Horizontal Die Retraction for Floor Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressing machines with a lower cylinder positioned below the die increase the pressurization position, leading to reduced worker productivity and increased costs due to the need for higher floor heights.
Innovation Solution
A pressing machine design featuring a support member and movement mechanism that allows the base table to move from an operating position where the dies apply heat and pressure to a retracted position, intersecting the material transport direction, thereby reducing the need for elevated working heights and maintaining heater functionality during stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lower cylinder is disposed below the lower die to enable emergency lowering, then the pressurization position increases, but worker productivity decreases and floor height requirements increase
Solution Approach 1:
The support member is configured to move not only vertically (pressing direction) but also in a horizontal direction (second direction intersecting the first direction). This dimensional change allows the support member to retract horizontally away from the press object during emergency stops, eliminating the need for elevated pressurization positions while maintaining emergency stop capability.
2Reliability
If the lower cylinder is disposed below the lower die, then emergency lowering is enabled, but the overall cost increases due to elevated floor height requirements
Solution Approach 1:
By adding horizontal movement capability to the support member, the system achieves emergency stop functionality without requiring vertical elevation of the pressurization position. This eliminates the need for elevated floor heights and associated construction costs while maintaining the essential safety function.
3Productivity
If the support member moves in the second direction intersecting the first direction, then worker productivity increases, but device complexity increases
Solution Approach 1:
The movement mechanism combines vertical movement (first direction) and horizontal movement (second direction) into a single integrated support member structure. This merging of movement capabilities in different directions into one component achieves the productivity benefit without proportionally increasing overall system complexity.

Function Achieved in This Case
This design enhances worker productivity by eliminating the need for elevated working heights, reduces overall costs, and allows for quicker resumption of molding operations by minimizing heat transfer to the material during stops.

AI summary
A pressing machine that applies heat and pressure to a press object transported in a first direction includes a first die having a first heater, a second die having a second heater and being disposed above the first die, a support member that supports the first die and the second die, and a movement mechanism that moves the support member from a first position to a second position located in a second direction intersecting the first direction from the first position, in which the first position is the position at which the first die and the second die apply heat and pressure to the press object and the second position is the position at which the first die and the second die do not face the press object.
