Scope of application
1. It is widely used in cold stamping processing industries such as screen mesh, cap making, can making production line, public facilities, sports equipment, instruments, electric control cabinet boards, motors, electrical appliances, lock making, hardware, solar water heaters, battery iron plates, building decorative panels, automobile and bicycle accessories, medical equipment, metal furniture, paper making machines, silencing boards, LED lamps, kitchen equipment, etc. 2. The existing turret punch manufacturers are used as auxiliary equipment for punching process. For example, punching holes with various patterns to reduce manufacturing costs. (Reduce power consumption, unit hour processing fee and operating cost.) 3. For developing sheet metal manufacturers that are not equipped with turret punching machines, punching process and sheet metal part contour processing, reduce start-up investment, improve processing efficiency and accuracy, and reduce industrial accidents compared with conventional punching. 4. Hardware stamping industry, such as can making, bottle cap making, lamps, steel mesh, etc., and decoration industry, such as screen punching holes, decorative plate holes. Compared with ordinary punching, it can improve the production efficiency. The use of sleeve punching distribution punching can improve the material utilization rate. At the same time, it does not need to hold the workpiece by hand, and the production safety is improved.
Whether it is the traditional air feeder clamping plate feeding, or the current common high-speed roller feeder, NC servo feeder, high-speed clamping feeder cylinder clamping feeding, will not scratch most common materials. Of course, for some special stamping industries, if the raw materials are gold, silver, copper, aluminum and other soft surfaces that are easy to damage, and the stamping products have high requirements for surface degree, then the standard machine may be scratched.
The service life of CNC punch feeder is closely related to the user's maintenance of the equipment. Users who use CNC punch feeder must be operated by trained personnel, and special personnel shall be assigned for maintenance. 1. The CNC punch feeder machine tool and machine tool parts shall be checked regularly to see if the screws of the machine tool fasteners are tight. If the screws are loose during movement, tighten them immediately. The iron chipping and waste materials on the machine tool shall be cleaned every day. 2. The guide rail and lead screw of the CNC punch feeder shall be lubricated frequently. The purpose of lubricating oil is to reduce the friction resistance and friction wear, reduce the temperature when the CNC feeder is moving, and play a protective role. 3. After the CNC punch feeder has been used for a certain period of time, the accuracy of the machine tool may have problems due to the serial clearance of the lead screw. At this time, the gland of the motor base can be removed, and 0.2mm copper sheet can be padded, which will be much better. The other is to check the coupling between the lower motor and the screw rod and whether the rubber elastic pieces are damaged, which also has an impact on the accuracy of the feeding machine of the numerical control punch. If damaged, replace it immediately.
At present, there are three main configuration forms of spindle bearing of CNC punch feeder.
(1) The front support adopts double row short cylindrical liquid bearing and double row 60. Angular contact ball bearing assembly. The rear support adopts diagonal contact ball bearing. This configuration can greatly improve the comprehensive stiffness of the spindle and meet the requirements of strong cutting. It is now widely used in the spindle of various machine tools.
(2) Double row angular contact ball bearing is adopted. Angular contact ball bearing has good high-speed performance, but its bearing capacity is small, so it is only used in the spindle of high-speed, light load and sophisticated CNC punch feeder. In order to improve the bearing capacity of the main shaft of the machining center, sometimes the front support combined with three four corner contact ball bearings is used, and the spacer sleeve is used to achieve preloading.
(3) Double row and single row tapered bearings are used. This bearing has high radial and axial stiffness, can withstand heavy loads, especially large dynamic loads, and has good installation and adjustment performance. However, this bearing configuration mode limits the high speed and accuracy of the spindle, so it is only applicable to the spindle of CNC punch feeder with medium precision, low speed and heavy load.
Adjusting the release angle of the press feeder: In actual use, many operators use the feeder with reliable quality. After replacing a new die for the press, they often only remember to adjust the height of the feeder. Because after replacing the die, the die height is different, and the feed height needs to change, which is very intuitive, but they ignore the adjustment of the release angle of the feeder, At this time, there will be inaccurate feeding. The operator is not familiar with the feeder and often can't think of the problem. At this time, the operator will complain that the feeder is not good and can only be used for one kind of mold. In fact, this is because the release angle of the feeder is not adjusted correctly, resulting in inaccurate feeding.
In the production and manufacturing process, the parallelism of the guide rail of the CNC punch feeder and the transmission accuracy of the lead screw directly affect the accuracy of the step punching, so mechanical assembly is very important. Secondly, the technology of control software and the selection of electrical appliances and motors are also very important. At present, stepping motor and servo motor are generally selected as the main drive of CNC punch feeder. In contrast, the driving accuracy of the servo motor is higher. Later, the perpendicularity and parallelism of the CNC punch feeder with the mold during the installation process are also important factors for product processing quality.
