Abstract

A pneumatic punch consists of a cylinder and a lever force amplifying mechanism, wherein the cylinder substitutes for the motor of an electric punch; and the lever force amplifying mechanism substitutes for the belt transmission, gear transmission and crankshaft linkage mechanism of the electric punch. Accordingly, the pneumatic punch overcomes the disadvantages of the electric punch, such as large power consumption, heavy weight, high cost, large difficulty in manufacturing, installing and maintaining the belt wheel, the gear and the crankshaft, large noise, and environmental pollution. By adopting clear compressed air as the drive force, the pneumatic punch has the advantages of simple and reasonable structure, energy saving and high efficiency, low cost and small impact vibration and noise, and can purify the operation environment.

Description

Pneumatic punching machine

Technical field

The utility model relates to the sheet stamping process equipment, particularly a kind of pneumatic punching machine.

Background technology

At present, operations such as the blanking of all kinds of thin plates (steel plate, aluminium sheet, copper coin, corrosion resistant plate, plastic plate etc.), moulding, side cut, shaping all adopt electronic punch press (claiming inclinable power press again) to finish.But electronic punch press adds and has the following disadvantages man-hour carrying out sheet stamping: 1. transmission efficiency is low, the energy consumption height; 2. parts such as motor, big belt pulley, gear wheel and bent axle are very heavy, and their manufacturing, installation and maintenance difficulty are big; 3. complete machine manufacturing cost height; 4. noise is big during operation, contaminated environment.

The utility model content

At the above-mentioned deficiency of electronic punch press, the purpose of this utility model provides a kind of pneumatic punching machine of efficient energy-saving.

The technical solution of the utility model is: 1. replace the motor of electronic punch press with cylinder, piston and piston rod in the cylinder are threaded with support, and support and lever boosting mechanism are hinged; 2. the belt transmission, gear drive and the crankshaft connecting rod system that replace electronic punch press with lever boosting mechanism, lever boosting mechanism is made up of mutually hinged support lever upper bracket, short lever, triangle lever, long lever and lever undersetting.

The utility model has the advantages that: 1. energy-conservation, general comparable motor punch press is energy-conservation more than 50%, and the power of output can increase several times to tens times, the work efficiency height; 2. cancelled heavy motor, belt transmission, gear drive and crankshaft connecting rod system, the structure of lever boosting mechanism is obviously simplified, and complete machine weight alleviates greatly, and production cost reduces; 3. using compressed air is power, and not only economy but also clean had been complied with the requirement of the environmental protection and the Scientific Outlook on Development; Can in time regulate drawing velocity as required when 4. working, alleviate the punching press vibration, reduce the punching press noise, purify operating environment.

Description of drawings

Fig. 1 is the structural representation before the utility model punching press;

Structural representation when Fig. 2 is the utility model punching press.

The specific embodiment

Now in conjunction with the accompanying drawings, technology contents of the present utility model is described in detail.

Cylinder (1) is fixed on the air cylinder base (4), piston and piston rod (2) place cylinder (1) to be threaded with support (3), support (3) is hinged with short lever (6), 2 lever upper brackets (5) are fixed on air cylinder base (4) bottom, 2 short levers (6) are hinged with support (3) and triangle lever (7) respectively, 2 triangle levers (7) are hinged with lever upper bracket (5), short lever (6) and long lever (8) respectively, 2 long levers (8) are hinged with triangle lever (7) and lever undersetting (9), and 2 lever undersettings (9) are fixed on the slide block (10).

Operation principle:

1. the state before the utility model punching press as shown in Figure 1.

2. the state during punch process as shown in Figure 2: piston in the compressed air-driven cylinder (1) and piston rod (2) move downward; At this moment, the support (3) that is threaded with piston and piston rod (2) drives short lever (6), triangle lever (7) and long lever (8) simultaneous displacement.When triangle lever (7) and long lever (8) between lever upper bracket (5) and lever undersetting (9) linearly the time, punch die (12) motion downwards of slide block (10) and upper trimming die (11), punch process is finished.

Claims

1. pneumatic punching machine, comprise slide block (10), upper trimming die (11), following punch die (12) and lathe bed (13), it is characterized in that cylinder (1) is fixed on the air cylinder base (4), piston and piston rod (2) place cylinder (1) to be threaded with support (3), support (3) is hinged with short lever (6), 2 lever upper brackets (5) are fixed on air cylinder base (4) bottom, 2 short levers (6) are hinged with support (3) and triangle lever (7) respectively, 2 triangle levers (7) respectively with lever upper bracket (5), short lever (6) and long lever (8) are hinged, 2 long levers (8) are hinged with triangle lever (7) and lever undersetting (9), and 2 lever undersettings (9) are fixed on the slide block (10).
