Automatic Round & Square Tube Hole Pulling Machine

The Automatic Round&Square Tube Hole Pulling Machine is a specialized numerical control metal processing equipment designed for precision hole pulling,flanging and hole forming on round tubes,square tubes and rectangular hollow profiles.Different from ordinary punching machines that simply cut through materials,this professional hole pulling equipment completes integrated processes including automatic feeding,precise positioning,hydraulic extrusion,one-piece hole flanging and shaping.It is mainly used to form vertical flanged holes on pipe surfaces,which greatly improves the strength,assembly performance and welding convenience of tubular workpieces.Effectively solving common industry pain points such as manual flanging distortion,low efficiency,uneven hole height and poor verticality,the machine has become ideal automated processing equipment for guardrail manufacturing,furniture pipe processing,solar pipe fittings and metal profile factories.

Built with heavy-duty welded steel frame and high-rigidity mechanical structure,the equipment maintains stable and vibration-free operation during high-pressure hole pulling and flanging processes.Equipped with high-precision servo positioning system and specially customized hole-pulling dies,the machine adopts gradual hydraulic extrusion technology instead of impact punching.This professional processing method ensures that the metal material is stretched evenly without cracking,warping or pipe wall deformation.The finished flanged holes feature uniform height,smooth roundness,vertical hole walls and consistent aperture size.The overall forming quality greatly enhances the structural firmness of subsequent bolt assembly and welding construction,fully meeting high-standard industrial manufacturing requirements.

This machine boasts outstanding dual-spec compatibility and flexible production capacity,supporting both round tubes and square tubes of various specifications.It is widely adaptable to carbon steel,galvanized steel,stainless steel and alloy tubular materials commonly used in the metal processing industry.Operators can freely adjust core parameters such as hole position,hole spacing,flanging height,hole diameter and processing speed through the intelligent touchscreen system.It can realize single-sided hole pulling,double-sided symmetrical hole pulling and multi-row staggered flanging processing.Fast die replacement allows quick switching between round tube and square tube production modes,enabling manufacturers to handle diversified customized orders and enrich product lines efficiently.

In terms of production efficiency,the fully automatic integrated workflow completely replaces traditional manual positioning,drilling and secondary flanging processes.After one-time pipe loading,the machine independently completes feeding,precise positioning,hydraulic hole pulling and finished product discharging,realizing continuous unmanned cyclic production.It greatly reduces manual intervention,saves labor costs and shortens processing cycles.Built-in anti-deviation correction device and constant-pressure hydraulic control system effectively avoid pipe body torsion and defective flanging,significantly improving material utilization rate and finished product yield.With stable operating performance and low failure rate,the equipment fully adapts to long-hour,high-volume industrial batch production.

Featuring humanized intelligent configuration,the machine is equipped with an intuitive CNC touchscreen HMI.It supports digital parameter setting,multi-group production formula storage,one-key mode switching and real-time production monitoring.Workers can complete equipment debugging and product specification replacement quickly without professional technical training,effectively lowering workshop operation thresholds and improving production efficiency.Comprehensive safety protection mechanisms including overload protection,emergency stop function,material shortage detection and automatic fault alarm ensure safe and reliable long-term operation.The modular structural design simplifies daily inspection,die maintenance and wearing part replacement,reducing enterprise operating costs.

Tubular workpieces processed by this machine feature high-precision flanged holes,stable structural strength and excellent assembly consistency.They are widely applied in road guardrail pipes,metal furniture frames,solar equipment pipes,mechanical support pipelines,fitness equipment and architectural metal accessories.With dual-tube-type processing capacity,superior hole forming quality,high automation level and remarkable cost performance,the Automatic Round&Square Tube Hole Pulling Machine has become a preferred intelligent processing solution for global metal pipe manufacturing enterprises,providing standardized and high-efficiency flanging production support for the modern tubular profile processing industry.
