Punching Device Cam Block Force Boosting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing punching devices are large in size and have limited output, making them inefficient for compact installations and requiring high drive unit power for effective hole formation.
Innovation Solution
The punching device incorporates a driving force transmission mechanism with inclined sections that convert the drive unit's force perpendicular to the rod's displacement direction, enhancing output and reducing device width by using a slider and cam block system with power boosting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional punching device configuration is used, then the device structure is simple, but the device width is large and the output is limited
Solution Approach 1:
The drive shaft is arranged substantially perpendicular to the direction of displacement of the slider, changing the force transmission direction from parallel to perpendicular. This dimensional change allows the drive unit to be positioned above the slider rather than alongside it, reducing the device width while maintaining force transmission capability through the inclined sections
Solution Approach 2:
The first and second inclined sections act as intermediary elements that convert the driving force direction. The first inclined section converts the perpendicular drive shaft force into horizontal slider movement, while the second inclined section converts it back to vertical rod pressing force, enabling compact arrangement without losing output capability
2Power
If the drive unit power is increased to achieve effective hole formation, then the output is improved, but the device size increases
Solution Approach 1:
The inclined sections change the mechanical parameters of force transmission by converting force magnitude and direction. The perpendicular arrangement of the drive shaft with the slider allows for more efficient force utilization, achieving the required output with a smaller drive unit power rating, thus reducing overall device size

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the device's transverse dimension, boosts the output applied to the rod, and allows for efficient hole formation with a smaller drive unit, enabling compact installation and versatile machining capabilities.

AI summary
A punching device (10) includes a body (12), a drive unit (18) connected to an upper part of the body (12), and a cam block (76) that moves in a horizontal direction in the interior of the body (12) under a driving action of the drive unit (18). A second rotating roller (108), which is connected to a rod (16), is inserted in a second cam groove (96) of the cam block (76). The second cam groove (96) includes first and second groove portions (98, 100) inclined at predetermined angles with respect to the direction of movement of the cam block (76), such that when the rod (16) descends downwardly toward a workpiece (W), a second rotating roller (108) moves from the second groove portion (100) to the first groove portion (98) having a smaller angle of inclination, whereby the driving force transmitted to the rod (16) is boosted in power.
