Description

a pneumatic punch

technical field

The utility model relates to the technical field of punching machines, in particular to a pneumatic punching machine.

Background technique

Punching machine is an important machine tool for mechanical processing, which is used to punch plates. Many punching machines are only used to process smaller workpieces, usually continuous feeding of plates and continuous stamping. The traditional pneumatic punching press produces less pressure. If a larger punching force is required, a cylinder with a larger bore diameter must be selected, which makes the punch press too large and requires a higher site. Come higher demands.

Utility model content

The purpose of the utility model is to design a pneumatic punching machine with a cylinder and connecting rod booster structure, which not only has a small volume, but also can amplify the punching force several times, so as to meet the requirements of modern production on the punching machine and production efficiency.

In order to achieve the above object, the utility model is achieved through the following technical means: a pneumatic punching machine, including a base, a bracket, a cylinder, a cam, a fixed plate and a punch, the base is vertically provided with a bracket, and the upper end of the bracket is The right side is provided with a fixed plate, and the upper end of the fixed plate is equipped with a cylinder, which can drive the cam below the fixed plate to move up and down through the piston rod. It is an arc surface contact; a support plate is provided on the left side of the upper end of the support plate, and a stroke adjustment device that can control the movement of the connection plate below the support plate is provided on the support plate; the connection plate is movably connected with an upper link. The upper connecting rod is movably connected to the lower connecting rod through a pulley, and the lower end of the lower connecting rod is connected to a slider, which can slide up and down in the limit block fixed on the left side of the bracket, and a punch is fixed at the end of the slider .

Compared with the prior art, the beneficial effect of the utility model is: due to the adoption of the above structure, the cylinder is used as the power source, and the cylinder drives the cam to act on the pulley connecting the upper connecting rod and the lower connecting rod, so that the pulley moves in a curve, not only Give the pulley a horizontal downward force, and also give the pulley a horizontal force. The pulley transmits the horizontal force to the upper and lower connecting rods and then becomes a vertical force, so that the connecting rods amplify the corresponding force twice and increase the momentum. , to achieve twice the momentum amplification. The utility model has novel structure, ingenious conception and wide market value.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1, the utility model: a kind of pneumatic punching machine, comprises base 1, support 2, cylinder 5, cam 6, fixed plate 3 and punch 14, and described base 1 is vertically provided with support 2, and the upper end of support 2 The right side is provided with fixed plate 3, and the upper end of described fixed plate 3 is equipped with cylinder 5, and this cylinder 5 can drive the cam 6 below fixed plate to move up and down by piston rod, and this cam 6 left lower part is arc-shaped surface structure, can Through the bracket 2, it can be in contact with the pulley 11 as an arc surface; the left side of the upper end of the bracket 2 is provided with a support plate 4, and the support plate 4 is provided with an adjustment travel device 7 that can control the movement of the connecting plate 8 below the support plate 4. The connecting plate 8 is movably connected with an upper link 9, and the upper link 9 is movably connected with the lower link 10 by a pulley 11, and the lower end of the lower link 10 is connected with a slider 12, and the slider 12 can be fixed Slide up and down in the limit block 13 on the left side of the bracket 1 , and a punch 14 is fixed at the end of the slide block 12 .

1 and 2, when the utility model works, start the cylinder 5, and the cylinder 5 drives the cam 6 to act on the pulley 11 through the piston rod, not only giving the pulley 11 a vertical downward force, but also a horizontal force to the left ; Since the upper end of the upper link 9 connected by the pulley 11 is fixed, the horizontal force to the left drives the upper link 9 and the lower link 10 to move downwards, making it move vertically downwards, thereby achieving The amplification of the impact force finally processes the workpiece by the punch 14 at the lower end of the slide block 12 .

The exemplary embodiments of the utility model are not self-limiting, and any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model without departing from the content of the technical solution of the utility model are still in effect. It belongs to the scope of the technical solution of the utility model.
