China-Semi-Auto-Hairpin-Bender-SSHB-
The Semi-Automatic Hairpin Bender is specifically designed and manufactured to meet medium-scale production demands. It features manual loading and unloading of straight tubing, while the bending process is driven by a high-precision servo motor, ensuring accurate length control. The machine is suitable for tubing with an outside diameter ranging from 7 to 16 mm, and it can produce hairpin bends with lengths of 200 mm, 1250 mm, 1600 mm, or 2000 mm, offering flexibility for various applications.
**II. Structural Features:**
The machine boasts a compact design, featuring hydraulic drive, manual feeding, and the option to operate in either manual or automatic mode. In automatic mode, the process includes material feeding (by hand), mold clamping, oil spraying, bending, mandrel retraction, clamp release, unloading, return to home position, and tooling reset, ensuring a smooth and efficient workflow.
**III. Main Components:**
The control system is available as a Mitsubishi option, providing reliable and advanced control. Pneumatic components are sourced from SMC, known for their quality and durability. Hydraulic parts are supplied by YUKEN, ensuring stable performance. All electrical components, including limit switches, switches, main switches, connectors, and relays, are high-quality and meet relevant safety standards.
**IV. Acceptance Testing Standards:**
- The difference in leg length of the hairpin should be less than 0.5 mm.
- No visible collisions, bumps, or corrugation should be present.
- Ellipticity should be less than 8%.
- Roundness tolerance of the straight section must be within ±0.3 mm.
- Parallelism between the two straight legs should not exceed 3%.
- The machine should run smoothly without any issues.
**V. Machine Performance Parameters:**
- Working efficiency: 12 seconds per cycle, based on a 1-meter tube example.
- System pressure: Hydraulic system ≤ 7 MPa; pneumatic pressure ranges from 0.5 to 0.7 MPa.
- Pneumatic air consumption is 0.1 m³/min.
- Cooling is achieved through air cooling.
**VI. Additional Spare Parts:**
- 2 sets of bending mandrels
- 2 sets of mandrel connecting rods
- 2 sets of stripper tubes
- 1 set of sensor limit switch
- 2 pieces of bending oil hoses
**VII. Technical Documentation:**
- One set of maintenance manual
- One quality certification document
- A machine nameplate indicating the manufacturing date, serial number, and manufacturer information
**VIII. Customer Support:**
To better serve our clients, the supplier can purchase certain testing materials on behalf of the customer within China, making the process more convenient.
**IX. Machine Color:**
The standard color is bean green, though it can be customized according to the customer's preference.
**X. Warranty:**
A one-year warranty is provided from the date the machine arrives at the customer’s facility, excluding consumable or wear parts.
