Omnidirectional Transfer Trolley To Handle Dies 15 Tons

Mold Handling Challenges

As the core tooling in the manufacturing industry, heavy dies have heavy weight, high value, concentrated load, and stringent requirements on positioning accuracy, which may lead to huge losses due to bumping and deformation, and the slightest positional deviation may affect product quality and cause production line downtime.

In addition, the stamping and mold workshop is densely packed with equipment and narrow passages, so the traditional handling equipments have large turning radius and a lack of flexibility, which makes it difficult to realize efficient transfer and accurate alignment of molds and dies, thus exacerbating the handling problems.

Case Study Omnidirectional Die Transfer Cart

The customer in this case is a large auto parts manufacturer; the layout of its stamping workshop is compact, the mold storage area is close to the stamping equipment, and the width of the channel is only 3.5 meters, which makes it difficult for forklifts and cranes to shuttle flexibly.

The single weight of the molds to be handled by the customer reaches 12-15 tons, with dimensions of 3.2m×1.8m×1.5m, which is not only close to the upper limit of equipment loading, but also the center of gravity of the molds is shifted, which makes it easy for conventional handling equipment to tilt and realize multi-directional movement of the molds in the storage area, the access area, and the stamping presses, which is difficult to meet the demand of traditional equipment.

15 ton omnidirectional die transfer cart is customized, equipped with a wheat wheel omnidirectional walking system, reinforced load-bearing platform and precise positioning module, powered by a high-capacity lithium battery, with endurance covering 8 hours of continuous operation.

After the application, the mold handling efficiency is enhanced by 40% compared to traditional equipment to enhance 40%, the original need for two people to cooperate with the completion of the mold alignment of an hour, can now be completed within 30 minutes, and the whole process of no mold bumping, positional deviation problems, workshop operation safety and production continuity significantly improved.

What is Omnidirectional Heavy Duty Die Cart?

Omnidirectional die transfer cart is an industrial handling equipment with multi-directional movement capability, which can travel straight, traverse, diagonal, and 360-degree in-situ rotation without additional turning space, and is suitable for narrow workshops. Relying on the omnidirectional traveling mechanism and power distribution system, it realizes movement in all directions through independent control of wheel speed and steering, and responds to operational needs precisely.

The core components include three types: omnidirectional wheels, drive system, and control unit.

Load Capacity and Structural of Mold Transfer Trolley

The rated load of this type of transfer trolley is 15 tons, and at the same time, it is designed with a 1.5 times safety coefficient, so the actual maximum load capacity can reach 22.5 tons, which can cope with the problems of weight fluctuation of molds and load concentration, and avoid the structural fatigue in long-term use.

The body adopts Q355B high-strength steel to create a reinforced frame; the crossbeam and longitudinal beams are welded and reinforced, and the thickness of key load-bearing parts is increased to 20mm, which effectively disperses the concentrated load of the molds and prevents deformation of the frame.

The platform adopts anti-deformation design, the surface is milled to ensure flatness, the error is controlled within 0.5mm, and at the same time, it is equipped with anti-slip pads and mold positioning buckles, which not only avoids sliding of the molds, but also reduces the vibration impact on the precision of the molds in the process of handling, and improves the overall stability of the operation.

Power System and Control Configuration of Die Trolley

Power supply mode of lithium battery, equipped with 48V/200Ah high-capacity battery pack, supports fast charging function, charging 2 hours to restore 80% of the power, and has no exhaust emissions, low noise, suitable for flexible operation in a closed workshop environment, free from the cable dragging on the restrictions on the scope of movement.

The control configuration provides three operation modes: wireless remote control (control distance up to 50 meters, equipped with an emergency stop button), hand-held joystick (suitable for close precision alignment, delicate operation feel), and PLC interface (can be docked with the workshop MES system, to realize automated transfer scheduling).

Die transfer cart is equipped with a smooth start-stop function, acceleration and deceleration processes controlled by frequency conversion technology to avoid load impact, and a speed limitation module, with a no-load speed up to 5km/h, load speed control at 2km/h, taking into account the efficiency and safety.

Safety Features of Mold Transfer Trolley

In terms of safety protection, the body is equipped with infrared anti-collision sensors and mechanical buffer devices around the body, automatically decelerating when it detects an obstacle 50cm away and stopping in case of emergency when it is 20cm away, effectively avoiding the collision between die transfer cart and the molds and workshop facilities.

Load stability and braking system are linked to each other, equipped with electromagnetic brake and parking brake dual device, power failure or emergency stop can instantly lock the wheels to prevent trolley from sliding, and at the same time through the gravity sensing module real-time monitoring of the center of gravity of the molds, when there is a deviation in a timely manner to send out an alarm.

In order to protect the safety of personnel and equipment, battery electric flatbed trolley is also equipped with sound and light alarm devices, warning lights, overload protection module. The operator needs to be authorized to start the equipment, to ensure all-around avoidance of safety risks in the handling process, and to provide reliable protection for high-value molds.
