Double-head bending machine for cart handle production

Double-head bending machine to complete the handrail molding on both sides of the cart at once, compared with single-head machine or segmental stamping, in the four dimensions of efficiency, precision, cost and quality have obvious advantages.

1.High efficiency

double-head bending at the same time, once the completion of the left and right symmetry of the “U” shaped or space three-dimensional handrail, the beat can be compressed to 3-4 seconds / piece. There is no need to turn the head of the second clamping, when changing the type of parameters can be input into the touch screen at once, setup time <3 minutes.

2. High precision

servo dual-axis independent control, bending error ≤ ± 0.1 °, left and right mirror size error ≤ ± 0.5 mm, to ensure that the two sides of the handrail is completely symmetrical, subsequent welding/assembly without the need for a second shaping. 90 ° head rotation function can be easily realized in space bending, to meet the demand for ergonomic handrail tilt angle.

3.High material utilization

One time molding to reduce the intermediate cut off, repositioning of the material produced by the head, tube utilization increased by 6%-10%. Smooth corner transition, R angle uniformity, can reduce the size of the handrail profile, the whole vehicle packaging volume is reduced, and the amount of ocean freight loading increased.

4. High consistency and appearance quality

program automatically compensates for rebound, consistent curvature of the batch handrail, no indentation, no wrinkles on the surface, and more uniform adhesion of subsequent powder coating or plating. Fixed clamps + automatic oiling system, to avoid scratches on the tube wall, to enhance the grade of the finished product.

5. Low labor cost

One person can watch multiple machines at the same time, reducing labor cost by 30 %-50 % compared with single-head machine. Operation interface with fault self-diagnosis, reducing the dependence on debugging technicians.

6. Low mold investment

Quick change mold design, the same clamping mold can complete different pipe diameters, different center distance of the handrail; no need to open the mold for the left and right parts separately.

In addition to cart handrails, double-head pipe bender in the automotive, aerospace, marine, petrochemical, furniture, construction, home appliances, fitness equipment, and almost any other need for “symmetrical/mirror image bending” batch manufacturing scenarios, are more efficient, more stable accuracy, faster changeover, more labor-saving.
