Gear hot die forging automatic production design scheme, according to the production process, product characteristics, existing equipment and other conditions, design a fully automatic forging production line.

1 Project overview

• Workpiece: Gear
• Weight: 2kg
• Forging temperature: up to 1200°C
• Process: bar material flattening - forming - punching
• Forging method: 3 stations full forging

2 Functional objectives

• Automatic positioning of bar stock
• Oxide scale purging
• Automatic spraying of release agent
• The forging press has three stations for automatic loading and unloading
• Production cycle: 7s/piece

3 Design

3.1 Overall layout

The robot adopts four claws to grasp the workpiece in four processes at the same time: bar stock, flattening, forming, and punching. Move the distance between one process to complete 4 processes to load and unload at the same time.

The bar material of the intermediate frequency furnace cutting chute falls into the positioning device to realize the vertical positioning of the bar stock.

The unloading conveyor line adopts a chain conveyor.

3.2 Cycle time analysis

The time for the forging press slide to press down once is 2s, the spray time of the mold release agent is 2s, and the cycle beat of the press is 7s.

3.3 Device Description

The bar stock conveying adopts a double channel, and the workpieces on channel 1 are pushed to channel 2 one by one by using a cylinder to prevent the adhesion of the two bar stocks.

The design of gear forging robot loading and unloading scheme describes in detail how to use robots to realize forging automation

4 Summary

Small parts forging automatic production line is characterized by fast beat, production cycle 5 ~ 7s / piece, the use of robots to solve the main difficulty of forging loading and unloading is the beat problem, if it is multi-station, multiple robots, try to ensure the balance of each station.

The temperature of the hot template is 1200 °C, and the robot claw is mainly designed with heat insulation and cooling, and the temperature of the claw can be reduced by adding heat insulation panels or adding air cooling or water cooling.
