Product Overview

This double segments cold press mould for core drill bits is specially designed for room-temperature pressing of double core drill segments, adopting dual-cavity synchronous cold forming technology. Optimized for scenarios like concrete wall double-hole construction and stone double-hole docking processing, it achieves simultaneous precise pressing of two segments at ambient temperature, doubling production efficiency compared to single-hole moulds. Suitable for large-scale production of 50-200mm thin-walled drill double segments, especially for batch orders in automated production lines.

Product Features

Dual-cavity Synchronous Pressing Technology：Using a servo hydraulic dual-cylinder drive system for 0-80 tons constant pressure synchronous pressing, double-hole segment density deviation ≤±1.0%, pressing cycle shortened to 12s/group, doubling 产能 compared to traditional single-hole moulds while reducing energy consumption by 35%.

High-wear Resistance Composite Material System：The cavity is made of SKD11 die steel with vacuum quenching + cryogenic treatment, surface deposited with TiCN hard coating (2μm thickness), hardness up to HV2800, fatigue resistance increased by 50%, capable of withstanding 120,000 cold pressing cycles, extending mould life to 3 times that of similar products.

Double-hole Precision Positioning Design：Adopting laser positioning + guide pillar precision guiding structure, double-hole spacing accuracy controlled within ±0.05mm, segment coaxiality error ≤0.03mm, meeting double-hole concentricity requirements of thin-walled drills and reducing drilling yaw risks.

Quick-change Dual-cavity Structure：The mould uses a modular double-hole design, single dual-cavity module replacement time ≤8 minutes. With a hydraulic fine-tuning device, it supports 0.2mm-level hole spacing adjustment, adapting to fast switching of different double-hole segment specifications and compatible with multi-variety small-batch production.
