Solution Overview

Problem

Existing press devices require complex and time-consuming adjustments to form electrical terminals with precise dimensions, often necessitating disassembly and reassembly in a trial-and-error process to achieve accurate fine tuning of punch positions.

Innovation Solution

A press device with an adjustment mechanism that includes an actuator and transfer member, or a knob and threaded drive bolt, allowing for in-situ linear adjustment of the punch position without disassembly, enabling precise control over the bending of terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional adjustment methods using shims are used, then punch position can be adjusted, but the process requires disassembly and reassembly which is time-consuming and complex

Engineering Contradiction:
Improvepunch position accuracyVSAvoidadjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The invention replaces static shim-based adjustment with a dynamic threaded rod mechanism that allows continuous adjustment of punch position. The threaded rod engages with a nut and movable plate, enabling the punch to be positioned at any point within an adjustment range through rotation of the handwheel, eliminating the need for disassembly and reassembly.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention substitutes the traditional mechanical shim insertion/removal system with a threaded fastening system. The threaded rod converts rotational motion from the handwheel into linear displacement of the punch, providing precise and repeatable adjustment without requiring the press to be disassembled.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If traditional adjustment methods are used, then punch position can be changed, but multiple trial and error adjustments are needed which reduces productivity

Engineering Contradiction:
Improveterminal formation accuracyVSAvoidpress operational efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The adjustment mechanism allows the punch position to be pre-adjusted to the correct position before production begins. Once set, the position remains stable during operation, eliminating the need for repeated trial-and-error adjustments and maximizing productivity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mechanism provides visual feedback through the handwheel position and allows for precise incremental adjustments. The operator can observe the punch position changes in real-time and make fine adjustments until the exact desired position is achieved, reducing the number of trial runs needed.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If shims are added or removed to adjust punch height, then position accuracy can be achieved, but the device complexity increases due to disassembly requirements

Engineering Contradiction:
Improvepunch height controlVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The threaded rod and handwheel mechanism serves multiple functions: it adjusts punch height, maintains position stability during operation, and allows for quick re-adjustment if needed. This single integrated mechanism replaces the complex multi-step process of shim insertion, retention, and removal.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A press device for forming a work piece includes a punch and an adjustment mechanism. The punch is configured to move along a punch stroke toward a work piece located in a punch zone below the punch. The punch is configured to engage the work piece during the punch stroke to form the work piece. The adjustment mechanism is coupled to the punch. The adjustment mechanism includes an actuator and a transfer member. The actuator is rotationally coupled to the transfer member. The transfer member is operably coupled to the punch. The actuator is configured to rotate. The transfer member converts the rotational movement of the actuator into translational movement that advances the punch linearly from a first operative position relative to the punch zone to a second operative position relative to the punch zone to adjust a bottom location of the punch along the punch stroke.
