D28 Series Modular Jig and Fixture Table for Welding Shops

The D28 Series Modular Jig and Fixture Table for Welding Shops is a heavy-duty modular tooling table specifically designed for welding workshops. Its surface is covered with 28mm standard holes, allowing for the quick assembly of precise three-dimensional welding fixtures using various locating pins and clamps. It is particularly suitable for welding and assembling large and heavy workpieces, significantly improving operational accuracy and production efficiency.

Hole System Wear-Resistant Strengthening Process
The inner walls of the table's hole system utilize a diamond honing + ion nitriding composite process, resulting in a surface roughness of ≤Ra0.2μm and a hardness of over HV 850. Compared to ordinary nitriding processes, the wear resistance life of the hole system is extended by 3 times, allowing it to withstand high-frequency insertion and removal of locating pins (≥100,000 times) without wear or deformation, completely solving the common industry problem of decreased positioning accuracy after long-term use.

Table Stress Relief Process
After rough machining of the casting, a double artificial aging treatment (high-temperature tempering + natural aging) is performed to eliminate casting and machining stresses, ensuring that the table's flatness deformation is ≤0.02mm/m² per year under welding temperature differences of -20℃~200℃, preventing tooling accuracy drift caused by stress release.

Anti-Seizing Design for Accessories
The moving parts of the heavy-duty clamps and locating pins use self-lubricating graphite copper bushings, eliminating the need for regular lubrication and ensuring smooth operation even in the dusty and oily environment of a welding workshop; the copper bushings are temperature resistant up to 300℃, eliminating the risk of seizing at high temperatures.

Tooling Development Costs Reduced to Zero
Replacing traditional dedicated welding fixtures, eliminating the need to develop dedicated tooling for new products, saving tooling design costs (approximately 5000-20000 RMB/set) and manufacturing time (reduced from 30 days to 4 hours). In small-batch, multi-variety production scenarios, tooling costs can be reduced by over 90% in the first year.

Reduced Changeover and Labor Costs
Modular design reduces tooling changeover time from 4-8 hours to within 30 minutes, allowing for 2-3 more production batches per shift; simple operation requires only 2 hours of worker training, eliminating the need to hire highly paid professional tooling technicians, resulting in a 15%-20% annual reduction in labor costs.

Controllable Maintenance and Wear Costs
Components can be replaced individually (e.g., locating pins, clamps), eliminating the need to scrap the entire table; the cost of replacing a single component is only 1%-5% of the table cost; wear-resistant hole system extends lifespan by 3 times, extending maintenance cycles from six months to two years, resulting in a 60% annual reduction in maintenance costs.

Optimized Space and Logistics Costs
Multi-layer stacking storage saves 60% of workshop floor space; forklift slots are reserved at the bottom, eliminating the need for lifting equipment, reducing internal workshop movement costs by 80%; for international trade, it can be disassembled into table + components, increasing container utilization by 30% and reducing cross-border logistics costs by 25%.
