Self Drilling Screw Point Forming Machine

This Self Drilling Screw Point Forming Machine adopts precision indexing rotation positioning and high-speed cold extrusion forming technology, which can complete automatic feeding, positioning, tip trimming, angle shaping, edge polishing and discharging of self-drilling screws in one continuous process.

Compatible with various specifications of metal self-drilling screws, the equipment features stable operation, high forming precision and low defective rate. It is an essential core equipment for improving the drilling performance and qualified rate of finished self-drilling screws, widely applicable to hardware fastener manufacturing, construction screw production and automotive fastener processing industries.

Technical Parameters

The equipment supports full coverage of mainstream self-drilling screw specifications on the market, with stable and reliable technical parameters, meeting mass and customized production needs:

Machine Structure and Core Functions

The Self Drilling Screw Point Forming Machine adopts modular integrated design, with independent functional modules, reasonable layout and high operation coordination, ensuring high-precision and high-efficiency screw tip processing:

1. Automatic Feeding and Sorting Module

Equipped with vibration automatic feeding tray and precise sorting mechanism, it can automatically arrange and feed disordered self-drilling screw blanks, effectively avoid material stacking and missing feeding. The feeding speed is adjustable synchronously with the forming speed, realizing uninterrupted continuous feeding and greatly improving production efficiency.

2. Precision Indexing Positioning Module

Adopts high-precision cam indexing positioning technology, with accurate positioning error within 0.01mm. It can fix the screw workpiece stably, ensure the drill tip processing position is completely accurate, and avoid deflection and offset during tip forming, which is the key to ensure consistent screw drill tip quality.

3. High-Hardness Tip Forming and Trimming Module

The forming cutter head is made of imported high-speed steel alloy, with high hardness, wear resistance and high temperature resistance. It completes cold extrusion forming and edge fine trimming of the screw drill tip at one time, removing tail burrs, smoothing cutting edges, and forming standard drill tip angles. The processed screw tip has sharp cutting performance, fast drilling speed and no cracking during actual use.

4. Intelligent Parameter Adjustment System

Humanized touch screen operation interface, supporting one-key switching of different screw specifications. Users can freely adjust forming speed, drill tip angle, trimming depth and other parameters. The system supports parameter memory function, no need to reset repeatedly after specification replacement, which is convenient and efficient.

5. Fault Alarm and Safety Protection Module

Built-in material shortage alarm, material jamming protection, overload protection and automatic shutdown functions. When abnormal conditions such as no material, material blockage and equipment overload occur, the machine will automatically alarm and stop running to protect the machine body and molds, reducing production loss and equipment failure rate.

6. Automatic Dust and Chip Removal Device

Equipped with a special iron chip cleaning fan and chip collecting box, it can automatically clean the metal debris generated during screw tip forming, keep the processing area clean, avoid debris affecting forming precision, and reduce manual cleaning workload.

Complete Operation Instructions

1. Pre-Operation Preparation

Equipment Inspection: Check whether the machine body bolts, cutter head and positioning fixture are fastened firmly, confirm the forming cutter head is intact without wear and gap deviation, and clean the internal sundries and residual iron chips of the equipment.

Lubrication Inspection: Check the lubricating oil level of gears, bearings and transmission parts, ensure the oil quantity is sufficient, and start the automatic lubrication system for pre-oiling to reduce running friction.

Raw Material Confirmation: Prepare qualified self-drilling screw blanks that match the equipment processing specifications, ensure no serious deformation and impurity adhesion on the workpiece surface, and pour the raw materials into the vibrating feeding tray.

Parameter Setting: Turn on the power supply, enter the touch screen control interface, select the corresponding screw model, set the drill tip angle, forming speed and processing depth, and save the parameters.

2. Debugging and Formal Production Steps

No-Load Debugging: Start the jog mode, run the Self Drilling Screw Point Forming Machine without load for 3-5 minutes, check whether the transmission system, feeding system and forming mechanism operate smoothly without abnormal noise and jamming.

Trial Production Inspection: Carry out trial processing of 10-20 workpieces after no-load debugging is normal. Measure the drill tip angle, tip smoothness and workpiece size tolerance, fine-tune parameters according to the processing effect until the products meet the standard.

Automatic Mass Production: After the trial products are fully qualified, switch the equipment to automatic continuous operation mode. The machine will automatically complete feeding, positioning, tip forming, trimming and discharging, realizing unattended batch production.

Real-Time Monitoring: During production, regularly sample and inspect the finished screw drill tips, observe the equipment operation status, and deal with minor abnormalities such as material jamming in time to ensure stable production quality.

3. Standard Shutdown Operation

Normal Shutdown: First stop the feeding system, wait for all workpieces in the equipment to complete processing and discharging, then turn off the operation switch, cut off the power supply and clean the residual iron chips in the machine.

Emergency Shutdown: In case of equipment failure, workpiece jamming, cutter head collision and other dangerous situations, press the emergency stop button immediately to cut off the power supply, and carry out troubleshooting after the equipment stops completely.

Daily Maintenance and Precautions

1. Daily Maintenance

Clean the surface iron chips and dust of the equipment after daily work; check the wear of the forming cutter head regularly; replenish lubricating oil in time; check whether the feeding tray operates normally to avoid material blockage.

2. Weekly Maintenance

Fasten all loose connecting bolts; clean the lubricating oil circuit and chip removal device; calibrate the positioning precision of the indexing mechanism; check the sensitivity of the fault alarm system.

3. Monthly Maintenance

Replace the circulating lubricating oil; detect the wear degree of the alloy cutter head and replace worn parts in time; conduct overall precision calibration of the equipment to ensure processing tolerance meets the standard; inspect circuit and air pipeline aging.
