3. 700T Suspension-Type Puller
1.1 Equipment Overview
This machine is used for the pulling and sawing operations of extruded profiles from the extruder. Based on synchronization with the extrusion discharge speed, the pulling force value is set to straightly draw the profiles from the die cavity and cool them under tension, preventing uneven lengths, springback, or twisting deformation of the profiles, thereby improving the yield and surface quality of the profiles.
The triple-head dual-track puller consists of two sets of pulling heads and one synchronized automatic interrupt saw. Compared to the dual-track dual-head dual-puller, it simplifies production processes, reduces work cycle time, features a streamlined body structure, and is flexible and lightweight. The two fully functional pulling heads alternate in operation, significantly lowering return speed, thereby reducing equipment wear and making maintenance easier. This product overcomes challenges such as multi-hole molds, multi-cut per billet, deformation of thin materials, and high-speed extrusion of profiles, greatly improving production efficiency and yield rates.
This equipment is primarily used for pulling, saw-cutting separation, and conveying extruded aluminum profiles, suitable for pulling aluminum profiles extruded by 600–1000T presses.

VII. Detailed Technical Specifications of Automatic Heating Multi-Bar Long Aluminum Rod Hot Shear Furnace
1. Material Storage Rack and Conveying Mechanism: Constructed with precision-welded high-quality steel sections, the storage rack features an inclined surface design. Aluminum billets are placed on the sloped platform of the storage rack; pneumatic cylinders and indexing plates propel the billets toward the conveying mechanism. Simultaneously, hydraulic cylinders drive manipulators to support the billets, minimizing impact when they roll into the pushing mechanism. Roller chains coupled with reducer motors drive push plates to feed billets into the furnace.

2.1. Bar Outfeed Roller System: The infeed side rollers consist of furnace body supports, roller seats, and rollers, all made of heat-resistant materials. The outfeed side rollers are driven by an external reducer on the furnace, which rotates the roller shafts and rollers on several water-cooled bearing supports via a chain. This system enables the aluminum bars on the rollers to move reciprocally between the furnace and the hot shear machine for outfeed shearing or retraction back into the furnace for reheating.
2.2. Heating Circulation System: Composed of a circulation fan and air ducts.

The air intake duct is formed by a multi-groove suction port. The air outlet is directly connected to Foshan City Nanhai Minxing Machinery Co., Ltd.
Foshan City NanHai MinXing Machinery Pty., Ltd
Connected to the combustion chamber burner, the heated air is directed through the air duct and blown onto the aluminum billets via the air outlet. After heat exchange, the low-temperature air is drawn into the fan for cyclic heat recovery, while residual heat is discharged through the exhaust vents on the furnace body, ensuring the furnace maintains a balanced positive/negative pressure within the optimal working range.
2.3. Billet Transfer Mechanism: Composed of a push rod, transfer block, linkage rail, and hydraulic cylinder. High-temperature-resistant stainless steel materials and heat-resistant castings are used for the furnace components. This mechanism operates in a unidirectional step-by-step motion, advancing one aluminum billet toward the discharge rollers with each cycle. The smooth pushing action ensures even heating as the billets rotate inside the furnace.
2.4. Furnace Door: The door is actuated by a pneumatic cylinder to open and close for billet loading and unloading. Safety inspection doors at both ends are manually operated with reliable performance.
2.5. Combustion System: Consists of a main pneumatic valve, solenoid valves, actuators, combustion program controller, pressure switches, pressure gauges, combustion air fan, and burners. The solenoid valves, combustion program controller, UV sensor, and pressure switches are all high-quality, proven products, while other components are premium domestic brands. The system features stable and reliable performance; the combustion program controller includes automatic ignition, flame monitoring, flameout protection, alarm output, and purging functions, ensuring safety, reliability, and stability.
2.6. Temperature Measurement System: Composed of three sets of thermocouples, temperature modules, and a PLC controller, it achieves functions such as high-temperature alarms, low-temperature combustion, and standby heat preservation.
3. Hot Shear Machine (Simple Vertical Type): Cuts aluminum rods according to extrusion process requirements to meet the needs of the extrusion press.
3.1. Rod Feeding Wheel System: Consisting of rollers, transmission sprockets, brackets, etc., this mechanism is integrated with the rod discharge wheel system inside the furnace. It delivers aluminum rods from the furnace to the shear machine's inlet for cutting.
3.2. Main Frame and Hydraulic Cylinder: Composed of movable and fixed blade seats, frame plates, etc. After the aluminum rod enters the shear machine, it performs actions such as clamping the rod, cutting the rod, and ejecting and conveying the rod. The hydraulic cylinder is custom-made by a specialized manufacturer.
Machining, with sealing elements using temperature-resistant components from Japan and Germany, while other materials are crafted from high-quality steel. The guide rails are processed with wear-resistant tin bronze and feature a centralized lubrication system.
3.3 Shear Blades: Made from specially processed 4Cr5MoSiV1 (H13) material, offering long service life, clean cutting edges, and a shear gap adjustment mechanism to ensure cutting quality.
3.4 Manual Adjustable Length Mechanism: Composed of a handwheel, bracket, stopper, screw rod, and nut, enabling aluminum billet dimensions to be adjusted within the extrusion press's process requirements.
3.5 Billet Turning Mechanism: Consisting of a cylinder, turning chute, and support frame, it transports the sheared aluminum billets to the feeding mechanism. The components are made of high-quality steel.

I. Introduction to the Dedicated Closed Oil Cooler for Extruders
(1) Advantages of Closed Oil Coolers
1. Significant energy-saving effect, achieving approximately 30-50%30-50 \% higher energy efficiency compared to plate exchange cooling systems.
2. Simple design, eliminating the need for constructing concrete pools or laying long pipelines; no need to purchase cooling towers or plate exchangers. This saves space for pools and avoids the hassle and maintenance costs of cleaning plate exchangers, while also reducing electricity consumption and water loss, truly achieving energy-saving and consumption-reducing effects.
3. When hydraulic vulnerable parts such as relief valves and piston oil seals are not severely worn or leaking, the oil outlet temperature of the cooler can stabilize between 35-39^(@)C35-39^{\circ} \mathrm{C} . This temperature range represents the optimal working condition for hydraulic oil. (Note: This equipment is specifically designed for
Minxing Machinery
Hydraulic oil cooling for the extrusion press (excluding cooling for other auxiliary equipment).
(2) Working Principle
1. The hydraulic oil from the extrusion press is directly pumped from the oil tank through a circulating oil pump to the cooler. It undergoes heat exchange via water sprayed on the outer surface of the tubes, while the hot air vaporized by the cooler is expelled upward by counter-flowing air. Simultaneously, the sprayed water, cooled by the air, flows back into the water tank, achieving a continuous spray cycle through a high-efficiency, low-lift spray fountain. The coolers produced by our company are made of 304 stainless steel, ensuring a long service life.
