Knowledge of punch maintenance: the use and characteristics of punch.

Stamping production is mainly aimed at sheet metal. Blanking, punching, forming, stretching, trimming, fine punching, shaping, riveting and extruding parts can be made through the die, which is widely used in various fields. For example, we use switch sockets, cups, cupboards, dishes, computer mainframes, and even missile planes ... there are many accessories that can be produced by punching machines through molds. Let me tell you something about punching machines. Let's have a look.

Working principle of punch press

The design principle of punching machine is to convert circular motion into linear motion, and the flywheel is driven by the main motor, and the gear, crankshaft (or eccentric gear) and connecting rod are driven by the clutch to realize the linear motion of the slider. The motion from the main motor to the connecting rod is circular.

For circular motion and linear motion, there must be a connection point between the connecting rod and the slider. There are two kinds of mechanisms in its design, one is ball type, and the other is pin type (cylindrical type). Through these two mechanisms, the circular motion is transformed into the linear motion of the slider. The punch presses the material to plastically deform it, thus obtaining the required shape and accuracy. Therefore, it is necessary to cooperate with a set of molds (divided into an upper mold and a lower mold) to put the material between them, and the machine exerts pressure to deform it. The reaction force caused by the force applied to the material during machining is absorbed by the main body of the punching machine.

Use and characteristics of punch press

Punch machines are widely used in the stamping of electronic, communication, computer, household appliances, furniture, vehicles and (automobiles, motorcycles and bicycles) hardware parts.

1.( 1) The high-rigidity and high-precision frame is welded with steel plates, and the internal stress of the fuselage technetium is eliminated after heat treatment, so that the equipment can work stably for a long time without deformation.

⑵ The structural members are uniformly stressed and the stiffness is balanced.

2. Stable high precision

The main parts of the equipment, such as crankshaft, gear and transmission shaft, have high wear resistance and long-term stability after hardening heat treatment, which ensures the requirements of high precision and stability.

3. Reliable and safe operation performance

The reason for convenient operation and accurate positioning is that it is different from the traditional brake.

The combination device of clutch/brake has high sensitivity, and the double electromagnetic control valve and overload protection device widely used in international high-end equipment ensure the accuracy and safety of the high-speed movement and stop of the punch slider. 4. Automatic production, saving manpower and high efficiency.

Punch press can be equipped with corresponding automatic feeding device, with feeding error detection, pre-cutting and pre-cutting devices, and fully realize low-cost and high-efficiency automatic production.

5. Sliding block adjusting mechanism

Sliding adjustment is divided into manual adjustment and electric adjustment, which is convenient, reliable, safe and fast, and the accuracy can reach 0.1mm.

6. Novel design and environmental protection

Adopting advanced technology and design concept from Japan and Taiwan Province Province, it has the advantages of low noise, low energy consumption and no pollution.

Introduction of punch maintenance knowledge

1, cleaning, cleaning equipment.

2, guide the crankshaft, connecting rod refueling screw ball head shaft refueling.

3. Check whether the manipulator and clutch brake are normal.

4, oil, oil pump check whether in good condition.

5, holidays holiday punching table, guide rail, mold, etc. Do a good job of rust prevention.

6.3 months regularly check the operation of the transmission shaft, copper sleeve and bearing, and disassemble, refuel or replace it.

7. Check the manipulator clutch, disassemble and refuel, observe its wear and tear, and repair or replace it.

After-sales maintenance of punching machine

(1) Response and maintenance speed of punch manufacturers. To find out whether the punching machine manufacturer you bought has an after-sales service point in the local area,

Can equipment problems be dealt with at home in time? (2) Maintenance cost. Equipment is cheap. If after-sales maintenance is expensive, it is definitely not a wise choice to buy such equipment. The life cycle of punching machine is relatively long, so the current price and after-sales price of equipment should be added together for comprehensive selection.

(3), the difficulty of the purchase manufacturer's own maintenance. Some simple problems can be solved by yourself without going to the manufacturer to solve them.

The above is the introduction I brought to you. If you want to know more, please continue to pay attention to Qijia Consulting. Please look forward to more wonderful consultation.
