Davron Indexing Conveyor Oven System Streamlines Heat Treating Process

Davron has been commissioned to design and manufacture a natural gas indexing conveyor oven for a Tier 1 automotive supplier.

Chattanooga, Tennessee June 17, 2014


Davron Technologies, Inc. designed and manufactured the DTI-1140, a natural gas heated indexing conveyor oven system that heat treats engine components for a Tier 1 automotive supplier. The system includes one indexing conveyor oven, one quench tank, one rinse tank, and an automated pick-and-place system, which had to be precisely calibrated to streamline the customer's heat treating process and meet its demanding production requirements.

The heated chamber in the DTI-1140 indexing conveyor oven system includes four index positions that process 840 parts (530 pounds) in an eight-hour cycle. In the first zone, product ramps to temperature and then soaks in the next three positions. For the heat treat process to be successful, the product must never dip below the temperature reached in the first zone. Upon exiting the heated chamber, the product must be submersed in the quench tank within seconds. The DTI-1140's sophisticated heating and air distribution system, along with its pick-and-place system, ensure that both of these critical requirements are met.

The DTI-1140 features two zones of temperature control in the heated chamber. Each zone is individually controlled to enable flexibility in the temperature profile and utilizes its own natural gas burner and circulation fan. The DTI-1140 also includes one exhaust fan to meet NFPA standards for gas-fired equipment. The maximum operating temperature is 1000ᴼ F. The indexing conveyor oven features PLC control and all motion functions are controlled by servo for accuracy and speed. Both the quench and rinse tanks include electric heaters to ensure solutions are the required temperatures prior to the start of production. The quench tank also features a chiller to cool the solution after each cycle.

The useable dimensions of the DTI-1140 are 4'0" wide x 2'6" high x 29'8" long. The interior of the oven is made out of 16-gauge aluminized steel backed by ten inches of eight-pound density mineral wool insulation. The exterior is constructed of 16-gauge carbon steel backed by a structural steel frame and finished with high-temperature paint. The oven features four access doors for explosion relief and access to the heated chamber. Pneumatically operated vertical doors cover both the entrance and exit of the oven chamber.

Davron designed the DTI-1140 indexing conveyor oven system based on three criteria provided by the customer: the production rate, the product size, and the temperature profile for the heat treating process. Once the indexing conveyor oven system was manufactured, Davron did extensive acceptance testing and training with the customer at Davron headquarters in Chattanooga, Tenn., prior to shipment. The system was then disassembled, prepared and packaged for shipment, and installed at the customer's facility by Davron personnel.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
