About the working principle and inspection method of a single column hydraulic high-speed punch machine

Reading Time: 5 minutes

The punch machine press is a kind of punch machineing press equipment, which is an energy-saving energy source. Many accessories are produced by punch machineing tools. The operation performance is reliable and safe, which ensures the safety of high-speed movement and stop of the punch machineing block, and has low noise. and pollution-free. The following is an introduction to “the working principle and inspection method of a single column hydraulic high-speed punch machine”.

【Operating principle and characteristics of single column-plant hydraulic high-speed punch machine】

The working principle of single column hydraulic high-speed punch machine

The design principle of the single column-plant hydraulic high-speed punch machine press is to change the circular motion to linear motion, the main motor outputs power to drive the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod and other operations to achieve the linear motion of the slider, The movement from the main motor to the connecting rod is a circular motion.

Between the connecting rod and the slider, there needs to be a transition point for circular motion and linear motion. There are roughly two arrangements in its design, one is a ball type, and the other is a pin type (cylindrical type). Through this arrangement, the circular motion will be Change to the linear motion of the slider.

According to the requirements of the limited process, the main cylinder of the single column-plant hydraulic high-speed punch machine can end the basic working cycle of rapid downward movement, deceleration limit, pressure holding delay, pressure relief return, and intermittent (any orientation), and the pressure, speed and pressure holding time can be adjusted. The ejector hydraulic cylinder is mainly used to eject the workpiece, and it is required to complete the actions of ejection, retraction and intermittent.

For example, when the sheet is stretched, auxiliary actions such as lifting, intermittent and pressure return of the ejector hydraulic cylinder are required. Sometimes it is necessary to press the blank with a blank holder to prevent the periphery from wrinkling.

The single column-plant hydraulic high-speed press takes the possible output pressure (tonnage) of the main performance device (master cylinder) in the main movement as the main standard of the single column-plant hydraulic high-speed punch machine, and has been serialized. The tonnage of the top cylinder is usually 20% to 50% of the tonnage of the main cylinder. Now, the single column-plant hydraulic high-speed press adopts the self-developed double dead cycle servo system control method, which has a high degree of humanization, full automation, intelligence and powerful functions.

Features of single column hydraulic high-speed punch machine

1. The single column-plant hydraulic high-speed punch machineing system is a single column-pump, open-type and series-connected system, and a series combination of reversing valves is selected. Not only the actions of each arrangement can be carried out independently, but also during light-load operation, the lifting and reversing can be combined. action to improve work efficiency.

2. The balance circuit, locking circuit and braking circuit are selected in the hydraulic high-speed punch machineing system of each plant, which ensures the reliable operation and safe operation of the crane.

3. The three-position four-way manual reversing valve is used for reversing, which can not only control the reversing action flexibly and conveniently, but also control the flow through the handle operation, so as to realize the economical speed regulation. In the hoisting operation, this method of saving speed regulation and the method of controlling the engine speed can be used in combination to complete the micro-speed action of each working part.

4. Each three-position four-way manual reversing valve adopts the M-type neutral function, so that the system can be unloaded when the reversing valve is in the neutral position, which can reduce the power loss of the system, and is suitable for intermittent operation of cranes.

5. The single column-plant hydraulic high-speed press adopts a one-way variable hydraulic pump to supply oil to the system, and the energy loss is small.

6. Use the reversing valve to control the chuck, complete the change of high pressure and low pressure clamping, and adjust the size of high pressure clamping or low pressure clamping pressure respectively. In this way, the clamping force can be adjusted according to the working conditions, and the operation is convenient and simple.

7. The hydraulic motor of the single column-plant hydraulic high-speed punch machine can complete the indexing of the tool rest, realize stepless speed regulation, and can control the forward and reverse rotation of the tool rest.

8. The reversing valve is used to control the reversing of the hydraulic cylinder of the tailstock sleeve to realize the extension or retraction of the sleeve, and to adjust the pre-tightening force when the tailstock sleeve is extended to adapt to different needs. .

【How to confirm the punch machine of the precision stamping tool before changing the line】

Heju Precision Stamping Factory is an ODM/OEM professional manufacturer specializing in the design and manufacture of precision stamping dies and precision hardware stamping. The molds used for production can be exempted from the mold design fee, the agreed delivery quantity, the mold fee refund, the stamping production efficiency is high, and the processing cost is saved.

(1) First, check the punch machine according to the equipment inspection table.

(2) Check whether the tonnage, stroke and closing height of the punch machine are sufficient. When the precision stamping die is at the bottom dead center, the die height cannot exceed the upper and lower limits required by the punch machine press.

(3) Check whether the length of the precision stamping tool is in line with the size of the bed of the punch machine, and the upper mold clamping method. Whether the blanking hole of the platform under the punch machine is sufficient. (to prevent blockage)

(4) For those that need to be predicted, check whether the scissor switch of the punch machine is working, whether the blowing time is sufficient, and whether the counter is double-segment or single column-segment.

(5) Whether there is a vacuum cleaner. Whether the scraps inside the vacuum cleaner are cleaned up. Prevent mixing. Whether the punch machineing oil needs to be replaced.

(6) Check whether the upper and lower limits of the feeder height meet.

(7) Check the clamping method between the slider and the upper die seat on the punch machine press. 

(8) Whether the punch machineing speed meets the design requirements of precision stamping tools.

(9) Whether the discharge tray is running. Whether the feeder is running.

(10) Whether the punch machine can be operated without failure. Whether it conforms to the discharge method of the product

The above introduction about “the working principle and characteristics of the single column-plant hydraulic high-speed punch machine” and “how to confirm the punch machine of the precision stamping tool before changing the line”, I hope you can understand “the working principle and inspection method of the single column-plant hydraulic high-speed punch machine” “Bring help.
