Gantry punching machine manufacturers take you to understand the type of gantry punching machine equipment and specification selection method Gantry punching machine equipment type and specification selection method, small and medium-sized stamping parts production, the main application of open punching machine. Single column punching machine has convenient operating conditions, easy to install mechanized attachments, low cost; The open press has the advantages of feeding and discharging in left and right directions. However, the stiffness of this type of punching machine is poor, and the deformation of the bed under the action of the punching deformation force can destroy the clearance distribution of the punching die. Reduce the life of the die or the surface quality of the blanking part. In the production of large and medium-sized stamping parts, the multi-purpose closed punch machine. Among them, there are general purpose presses, and there are special extrusion presses with small tables and large stiffness, and so on. In the production of large drawing parts, double action presses can be selected, and the mold used is simple in structure and convenient in adjustment.

In mass production of gantry punch or mass production of complex parts, high-speed press or multi-station automatic pressure scraper should be selected; In small batch production, especially in the bending and forming production of large thick plate stamping parts, high-speed presses or friction presses are often used. The hydraulic press has no I.q stroke, and will not be overloaded because of changes in sheet thickness, which has obvious advantages compared with the punch when a large force stroke is required. However, the production rate of the hydraulic press is low, and the dimensional accuracy of the stamping parts is sometimes not very stable due to the influence of the operation cable. Friction press structure is simple, low cost, not easy to overload damage, commonly used to complete bending and other stamping work. Because the stroke of the friction press is not fixed, the flattening or shaping of the stamping parts is not affected by the thickness fluctuations of the plate, and the calibration accuracy is relatively stable. However, the friction press has fewer strokes, low production rate and inconvenient operation.

Development of high-speed punching technology: Process analysis of the main version of modernization, high-speed punching technology integrates the manufacturing cycle, saving a lot of labor and time. High speed punching die design quality improvement. Stamping production automation, in order to meet a large number of production needs, high-speed punching machine production has been developed in the direction of automation and unmanned. Now the use of high-speed punching machine to achieve a single automatic stamping speed of up to thousands of times per minute. The production of large parts has a multi-machine joint production line, from the feed of sheet metal, stamping processing to post-inspection all with computer control, reducing the labor intensity of workers, improve the production rate. At present, stamping production has gradually developed to the flexible stamping processing formed by unmanned production.
