Box Punching Machine with Internal Support for Precise Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing punching machines for box-shaped elements are complex, expensive, and lack precision and repeatability in producing through holes, often requiring special positioning and failing to effectively eliminate scraps.
Innovation Solution
A punching machine with a punch and counter-head system that allows automatic, precise, and repeatable production of through holes on vertical sides of box-shaped elements, using a counter-head to maintain the element in position and a suction device to remove scraps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex punching machines with special positioning means are used, then through holes can be made on box-shaped elements, but the device complexity increases and cost increases
Solution Approach 1:
Instead of moving the box-shaped element horizontally through complex positioning means, the invention inverts the approach by moving the punching head vertically downward onto the stationary box. The counter-head inserts inside the box to provide support, eliminating the need for complex external positioning mechanisms while maintaining punching precision.
Solution Approach 2:
The invention extracts the essential function of positioning from the complex positioning means by using the counter-head inserted inside the box-shaped element. The counter-head provides internal support and positioning at the punching location, removing the need for elaborate external positioning systems.
2Adaptability or versatility
If punching machines with rotation means are used, then through holes can be made on different sides, but the device complexity increases
Solution Approach 1:
The punching head is designed with multi-functionality to perform punching operations on different sides of the box-shaped element without requiring rotation means. By positioning the punching head and counter-head appropriately, the same vertical punching mechanism can punch any side that is accessible, eliminating the need for complex rotation or repositioning systems.
3Ease of manufacture
If manual punching methods are used, then equipment cost is reduced, but productivity decreases
Solution Approach 1:
The punching machine is designed for automatic operation where the punching head moves vertically to punch through the box-shaped element without requiring manual intervention for each punch. The system can automatically position and punch multiple holes, significantly increasing productivity compared to manual punching while keeping the device relatively simple in structure.
4Manufacturing precision
If traditional punching machines are used, then through holes can be produced, but scrap elimination is ineffective
Solution Approach 1:
The counter-head inserted inside the box-shaped element serves as an intermediary that supports the material during punching. This internal support structure allows for cleaner punching with better control over the punching process, improving scrap elimination by preventing material deformation and ensuring clean cuts.
