Primapress Recommended Large Bending Machine

The Prima series large CNC press brake features high speed, high precision, and strong rigidity. A large floor-type milling machine ensures the accuracy of the entire machine frame, including the parallelism of the cylinder mounting surface and the verticality of the worktable. The electro-hydraulic servo synchronization system precisely controls both the mechanical deflection compensation of the ram and the throat deformation compensation, thereby improving bending accuracy. In addition, a digital AC servo motor drives the precision ball screw and linear guide of the backgauge, ensuring stable and reliable positioning.

Processing Equipment

Advantages

Core Configuration

The CNC bending machine is important equipment in sheet metal processing, and its work accuracy directly affects the bending accuracy of the workpiece. In the bending process of the workpiece, the press brake machine is subjected to the greatest force at both ends of the slider, and the reaction force during the bending of the plate causes concave deformation on the lower surface of the slider. The deformation of the middle part of the slider is the largest, and the final bending angle of the workpiece The size varies across the entire length.

Workbench – Full Load Deformation

In order to eliminate the adverse effects caused by the deformation of the slider, it is necessary to compensate for the deflection deformation of the slider. The usual compensation methods include hydraulic compensation and mechanical compensation, both of which make the middle of the worktable produce upward elastic deformation to offset The deformation of the machine tool slide ensures the accuracy of the machining joint surface and improves the accuracy of the workpiece.

Column – Analysis Of Deformation Under Full Load

Introduction to two compensation methods

Hydraulic compensation method

The hydraulic automatic deflection compensation mechanism of the workbench is composed of a group of cylinders installed in the lower workbench. The position and size of each compensation cylinder are designed according to the deflection compensation curve of the slider and the workbench finite element analysis. The hydraulic compensation is achieved by the relative displacement between the front, middle and rear three vertical plates to compensate for the bulge of the neutral plate. The principle is to achieve the bulge through the elastic deformation of the steel plate itself, so the compensation amount can be adjusted within the elastic range of the workbench.

Mechanical compensation method

The CNC system calculates the value of compensation required according to the size of the load force when the workpiece is bending (the force will cause the deflection deformation of theslide r and the table riser), and automatically controls the relative movement of the convex wedge, so as to effectively compensate the deflection deformation generated by the slider and the table, and obtain the ideal bending workpiece.

How Do You Guarantee The Quality?

– We guarantee you the quality of our machine (e.g. processing speed and working performance will be the same as the data of the sample machine as well as your requirements). The contract will contain detailed technical data.

– We always arrange final testing of operation before shipment. The machine will be tested for a few days, and then use customer’s materials to test its performance. After we confirmed there are no problems with the machine, then the shipments will be arranged.

– We provide the machine with a 5-year warranty. Flexible extended warranties can be offered as agreed.

What kind of packing do you use for your machines?

– As our machines are large-scale equipment, they are usually directly loaded into containers and then fixed by steel wires, so that when the freighter is sailing on the sea, the machines will not hit the inside of containers because of the ship’s swing, so as to ensure that the machines are intact. In addition to the machine you ordered, the container will not put any other items.

How does your company provide after-sales service?

– For small problems in the process of using the machine, we will arrange mechanical engineers to help you solve them remotely, one-to-one guidance, such as sending text instructions or videos to teach you how to solve the problem. If the parts need to be replaced are within the warranty period, we will send them to you free of charge. Of course, you can also buy them locally (if you can buy them), which can save more time. For more serious problems, if the way of remote guidance is not working, we will arrange engineers to provide on-site service. For regions with agents, we will contact agents directly to provide services.

Does your company provide training?

– Yes, you can arrange relevant personnel to our company for on-site study, and we will arrange a special person for one-to-one guidance. If it is not convenient for you to come to our company, we can provide remote training.

How do you charge the ocean freight?

– As for the ocean freight, it is usually charged by the freight forwarder. You can use our freight forwarder to arrange the delivery, or you can use your own freight forwarder.
