300-1200mm Core Length | Plate-Fin Heat Exchanger Core Assembly Machine | Core Pre-tightening, Shaping & Tie-rod/Banding Assembly System

1. Product Overview

This equipment is specifically designed for manual-assisted assembly of plate-fin heat exchanger cores, completing pre-tightening, shaping, secondary pressing, tie-rod installation, and steel banding after core stacking. Featuring push-button manual control and pneumatic-hydraulic booster cylinders for pressing force, it offers convenient and efficient operation. Typical applications include assembly lines for various plate-fin heat exchanger cores, particularly suited for multi-variety, medium-to-small batch production.

2. Industry Challenges & Root Cause Analysis

Insufficient core verticality and diagonal accuracy:Stacked fins, separators, and bars tend to shift during pressing, resulting in excessive verticality deviation and diagonal errors. Root cause: lack of uniform pre-tightening and shaping procedures – uneven pressure distribution.

Imprecise pressing force control:Traditional pneumatic or mechanical pressing methods have fluctuating pressure and cannot precisely set force per product specification. Root cause: lack of pneumatic-hydraulic boosting mechanism – unable to achieve high force output from low-pressure air supply.

Low loading/unloading efficiency:Tie-rods or steel bands must be installed after pressing – traditional equipment offers cramped operating space in the pressed state. Root cause: lack of slide-out table function for convenient workpiece access.

Cumbersome multi-specification changeover:Different core heights, lengths, and thicknesses require adjustments at multiple positioning points – time-consuming. Root cause: lack of quickly adjustable clamp plate positioning and stroke adjustment mechanisms.

3. Solution

3.1 Efficient Pneumatic-Hydraulic Boosting Pressing System:Uses pneumatic-hydraulic booster cylinders for pressing force – driven by 0.4-0.7MPa compressed air, output adjustable 0-5T – no high-power hydraulic station required – energy-saving and environmentally friendly. Dual-cylinder synchronized clamping – each cylinder independently adjustable for different core sizes.

3.2 Precision Guide & Stroke Adjustment:Pressing action driven by stepper motor – speed 0-30m/min infinitely adjustable. Length stroke 300-1200mm adjustable; thickness stroke 30-200mm adjustable – accommodates multiple core specifications.

3.3 Worktable Slide-Out Function:After pressing, the sliding worktable extends outward approximately 260mm – provides ample operating space for tie-rod installation or steel banding – quick and convenient workpiece loading/unloading.

3.4 Step-by-Step Operation Process:Pre-press → shaping → secondary pressing. Pre-press for initial positioning – adjust verticality on both sides – secondary press to final position – ensures core verticality ≤±0.6mm, diagonal deviation ≤2mm (core size ≤1200×1100mm).

3.5 Push-Button Manual Control:Entire machine controlled via push-buttons – simple and intuitive – no complex programming training required. Equipped with emergency stop and pressure regulation for operational safety.

6. FAQ

Q1: What are the advantages of pneumatic-hydraulic booster cylinders over conventional cylinders?

A: Driven by standard compressed air (0.4-0.7MPa), the booster cylinder amplifies output force through area ratio – delivers 0-5T pressing force without a high-power hydraulic station – energy-saving, oil-free, and low maintenance.

Q2: How are core verticality and diagonal accuracy ensured?

A: Step-by-step process: pre-press for initial positioning – manual adjustment of verticality on both sides – secondary press to final position. Precision guide mechanisms ensure core verticality ≤±0.6mm and diagonal deviation ≤2mm.

Q3: What is the benefit of the worktable slide-out function?

A: After pressing, the table slides out approximately 260mm – provides ample space for tie-rod installation or steel band threading – avoids cramped operation inside the pressing zone – improves loading/unloading efficiency and safety.

Q4: Can the equipment accommodate different core specifications?

A: Yes. Length adjustable 300-1200mm, thickness adjustable 30-200mm – clamp plate positions quickly adjustable. No tooling replacement required for specification changes – mechanical adjustments only.

Q5: Does the equipment require complex programming?

A: No. Push-button manual control – simple and intuitive – ordinary operators can become proficient after brief training.
