Introduction Of The Function Of The Lamp Pole Bending Machine

At present, the common size of the turning machine table sold in the market is 4000 (mm), and the maximum size is generally not more than 6000 (mm). When the processing of ultra-long workpieces occurs, it is hoped that the two sets of linkages work together, that is, the molds of the two bending machines are arranged on a straight line, the sliders of the two bending machines are synchronously descended, and the workpiece is driven to bend the workpiece to meet the long length. Workpiece bending requirements.

At present, the main technical solutions for the synchronization of two bending machines are mechanical synchronization, electrical synchronization, and numerical control synchronization. Among them, the mechanical synchronization uses the mechanical transmission member to rigidly connect the sliders of the two bending machines, and forcibly realizes the synchronization of the two bending machines. The mechanical synchronization is simple to implement and reliable, but it limits the two bending machines to work independently. That is, when the machining is not too long, it is troublesome to disengage the two bending machines. The technical solution of the numerical control synchronization is to install the position detecting sensor on the sliders of the two bending machines, and use the proportional valve to control the flow into the cylinder, so that the sliders of the two bending machines are synchronously descended.

Although the numerical control synchronization can meet the requirements that the two bending machines can work together and work independently, the cost of the numerical control system and the proportional valve are relatively high. Only the numerical control system and the proportional valve are arranged on the high-grade bending machine, which limits the technology. Application in ordinary bending machines. The electric synchronization adopts the travel switch as the position detecting device, and the electric control method realizes the downward control of the sliders of the two bending machines. Since the sheet material is generally a steel workpiece, the value of the elastic modulus E is very large. During the bending process, the contact displacement between the tool and the workpiece, even if the increment is very small, will result in a very large contact force increment.

The use of the travel switch to detect the displacement of the slider of the bending machine and to control the synchronization of the two bending machines obviously has major technical defects, so the electrical synchronization method is difficult to implement in engineering. The double-machine synchronization of the bending machine essentially requires that the tools of the two bending machines simultaneously apply the bending force to the urea workpiece of the vehicle to ensure that the workpiece does not have warpage and offset during the bending process, and the workpiece is satisfied in two. The curved surface formed on the bending machine has the same shape, and the curved grooves are in a straight line. For the shortcomings of mechanical synchronization, electrical synchronization and numerical control synchronization, the new type of force control realizes the double-machine synchronization function of the bending machine.
