CNC punching machine can be used for all kinds of metal sheet parts processing. It can automatically complete a variety of complex hole types and shallow deep drawing forming processing at one time. (Automatically process holes of different sizes and hole distances according to requirements. Small punch The punching method punches large round holes, square holes, waist-shaped holes and various shapes of curve contours, and can also be processed by special processes, such as blinds, shallow stretches, countersinks, flanging holes, ribs, embossing, etc.) . Through simple mold combination, compared with traditional stamping, it saves a lot of mold costs, can use low cost and short cycle to process small batch, diversified products, has a large processing range and processing capacity, so as to adapt to the market in time And product changes.

Maintenance and maintenance related knowledge of punch press

Add manual lubricating grease to flywheel bearings and check pipelines and joints. Check the operation status of the cylinder and the oil circuit of the gasoline lubrication system and the joint circuit. Test and check the insulation resistance of motor circuits and electrical operation circuits. Test the accuracy of the whole machine (perpendicularity, parallelism, full gap, etc.), and adjust the correction if necessary. The appearance of the punch and the cleaning of appendices, the picking points and the (basic) fixing screws of the machine soles, the locking of the nuts and the level inspection can be adjusted if necessary. Cleaning, maintenance and inspection of the lubrication system and pipeline valves. Pneumatic components, pipelines, etc. of the oxygen system are cleaned, maintained, and motion tested.

Use 3000-4000 hours to maintain the photoelectric safety installation function test and throw angle and area test control. The appearance of other parts of the electrical system, contact wear and loose connection, etc., test and check and control the function of the second-degree automatic cam switch box and emergency stop circuit. Overload protection installation of oil circuit cleaning, oil chamber cleaning, oil renewal, pressure action and function test adjustment. The main motor V-belt wear and tension status check and control. The components of the brake release mechanism are disassembled (not included in the flywheel) for cleaning and maintenance, inspection and control of gaps, and reinstallation and debugging. The other parts of the leveling device are disassembled and used for disassembly, cleaning and inspection, and reassembly and debugging. Use 6000-8000 hours to maintain the saw tooth connecting rod, disassemble, clean and maintain, check the occlusal and abrasion state of saw teeth and connecting rod ribs, and polish, polish the occlusal surface and apply grease. Slider assembly (ball seat, press cover. Overload hydraulic cylinder, worm gear, worm, etc.) dismantle and disassemble, clean and maintain, gap control and wear surface, oil seal check and re-apply grease. Die pads are disassembled and cleaned, inspected for each wear surface, and re-applied with grease, then assembled and tested.

Problems to be paid attention to in turning process of CNC punch press

CNC lathe processing is necessary, the problem to be noted: The processing process of the CNC lathe is similar to that of the ordinary lathe, but because the CNC lathe is a clamping, continuous automatic processing completes all the turning processing. Therefore, we should pay attention to the following aspects.

1 Reasonably choose cutting parameters.

2. Reasonable choice of tools:

　(1) The high strength and durability requirements of rough turning tools are to meet the large depth and feed rate of rough turning.

　(2) For precision turning, choose high-precision and durable tools to ensure the accuracy requirements of the machining.

　(3) To reduce the tool change time and convenience, the machine clamped knife and machine clamped blade should be used.

3. Reasonable choice of fixture:

　(1) Try to use general fixtures to clamp the workpiece, avoid special fixtures;

　(2) The parts positioning datum coincides to reduce the positioning error.

4 Determine the processing route: The processing line is the index in the CNC machining process, the path direction of the tool and the relative part.

　(1) The machining accuracy and surface roughness requirements should be guaranteed;

　(2) The process flow should be shortened as much as possible to reduce the empty travel time of the tool. Rotor pump

5. Machining route and machining allowance: At present, when the CNC lathe has not yet reached the popularization of the punch press, the allowance should be generally on the blank, especially the arrangement with the ordinary lathe for forging and casting shell edges. If you must use CNC lathe processing, you need to pay attention to the flexible arrangement of the program.

6 points: The current installation fixture is realized by connecting a hydraulic cylinder and a hydraulic clamping cylinder. The hydraulic clamping points are as follows: first hand unload the hydraulic cylinder nut and remove the horn, and away from the rear end of the spindle, and then remove the screw by hand to remove the chuck chuck.

Tips for safe use of pneumatic punch

1. Keep it clean Before connecting the booster cylinder to the gas path, please remove the dust and other debris in the pipeline and components to avoid reducing the service life of the booster cylinder.

2. When used within the normal air pressure range, the working air pressure of the cylinder during normal use must work within the working air pressure range specified in the inspection report, and shall not exceed the specified working pressure.

3. Pay attention to the working environment of the booster cylinder. The temperature in the working environment of the cylinder has been determined during the design. If the working environment needs to be changed due to work, the temperature exceeds the temperature, please contact the relevant personnel of the booster cylinder technology. As part of the components in the cylinder are made of iron, please do not use them in a particularly complex environment (if there are chemical substances in contact with the environment), and please install effective air handling components at the front of the cylinder ( Three-point combination) add lubrication and drainage when parallel connection.

4. Do not add other hydraulic oil without authorization. The hydraulic oil used in the design of the booster cylinder is VG68# anti-wear hydraulic oil. It is irrevocable to use other liquid media (such as oil, water, etc.) without authorization.

5. Be sure to follow the procedure. The pneumatic punch manufacturer reminds that the action program must work in accordance with the action program of the gas circuit assembly diagram, that is, pre-pressure action-boost action, boost pressure release-pre-pressure reset.
