Description

Universal rubber pad cutter and its usage method

technical field

The invention relates to a universal rubber pad cutter, which is especially suitable for the universal rubber pad cutter with non-standard specifications for electrical equipment in the electric power sector.

Background technique

In the electrical equipment currently in use, most of the electrical equipment uses liquid or gas as the insulator medium to protect its safe operation, and a large number of rubber pads are used as sealing elements. The processing and manufacture of non-standard rubber pads with large diameters and ultra-thickness makes it difficult for construction workers to ensure their quality and precision requirements, the cutting efficiency is very low, the geometric shape is difficult to control, and it is easy to cause personal injury without special tools.

Contents of the invention

The object of the present invention is to provide a universal rubber pad cutter capable of making non-standard rubber pads, and further provide a method for using the cutter.

To achieve the above object, the present invention adopts the following technical solutions:

In the present invention, a universal rubber pad cutter includes a beam on which a fixed knife rest and a movable knife rest are slidably arranged; the fixed knife rest includes a positioning pin assembly, and positioning pins are arranged in the positioning pin assembly. The positioning pin can be unscrewed out of the positioning pin assembly, and a positioning pin lock nut is arranged on the positioning pin assembly; A blade locking nut is arranged on the frame assembly.

The fixed knife rest is fixed on the beam through the lock nut of the positioning body; the moving knife rest is fixed on the cross beam through the lock nut of the knife rest.

The beam is provided with a size scale.

A positioning pin handle is arranged on the top of the positioning pin.

A method for using a universal rubber pad cutter, comprising the steps of:

Step 1. Loosen the lock nut of the knife holder, adjust the position of the movable knife holder so that the distance from the movable knife holder to the fixed knife holder is equal to the outer circle radius of the required rubber pad, and then lock the lock nut of the knife holder;

Step 2, loosen the blade lock nut, adjust the feed rate of the blade, make the feed rate of the blade adapt to the thickness of the rubber pad required, and then lock the blade lock nut;

Step 3, unscrew the positioning pin and press it into the rubber pad, hold the positioning pin with the left hand, rotate the movable knife holder with the right hand and apply pressure downward; when the movable knife holder rotates one circle, the outer circle of the rubber pad required can be obtained;

Step 4: Adjust the distance between the movable knife rest and the fixed knife rest to make it equal to the inner circle of the required rubber pad; rotate the movable knife rest and apply downward pressure to cut off the inner circle to obtain the required sealing rubber pad.

The present invention adopts the above-mentioned technical solution, skillfully combines planer, cutter, and scale effectively, and easily completes the production of non-standard rubber pads, especially in terms of safety, high efficiency, and correct performance. Conventional practices are incomparable, making it more than ten times more efficient. The invention can not only reduce the labor intensity and improve the work efficiency, but also reduce the number of operators and ensure the personal safety of the operators. At the same time, the cutter is easy to use, light and comfortable, simple in structure, easy to process, novel in appearance, and convenient to obtain materials. The blade does not need to be customized, and ordinary broken blades can meet the use requirements.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the present invention includes a beam 2 on which a fixed knife rest 10 and a movable knife rest 11 are slidably arranged. In order to conveniently characterize the distance between the fixed knife rest 10 and the movable knife rest 11 , a dimension scale can be set on the beam 2 .

As shown in Figure 2, the fixed tool holder 10 includes a positioning pin assembly 7, and a positioning pin 1 is arranged in the positioning pin assembly 7, and the positioning pin 1 can be rotated out of the positioning pin assembly 7, and is arranged on the positioning pin assembly 7. Locating pin lock nut 6. For ease of use, a positioning pin handle 12 is provided on the top of the positioning pin 1 . For the convenience of positioning, the above-mentioned fixed knife rest 10 is fixed on the beam 2 through the locking nut 5 of the positioning body.

As shown in FIG. 3 , the movable knife rest 11 includes a knife rest assembly 9 , a blade 3 is arranged on the lower part of the knife rest assembly 9 , and a blade locking nut 4 is arranged on the knife rest assembly 9 . For the convenience of positioning, the above-mentioned movable knife rest 11 is fixed on the beam 2 through the knife rest lock nut 8 .

A kind of using method of universal rubber pad cutter among the present invention, it comprises the following steps:

Step 1: Loosen the lock nut 8 of the knife holder, adjust the position of the movable knife holder 11, so that the distance from the movable knife holder 11 to the fixed knife holder 10 is equal to the outer circle radius of the required rubber pad, and then tighten the lock nut of the knife holder 8.

Step 2, loosen the blade lock nut 4, adjust the feed rate of the blade 3, make the feed rate of the blade 3 adapt to the thickness of the required rubber pad, and then lock the blade lock nut 4; it should be noted that, The above-mentioned feed rate suitable for the required thickness of the rubber pad refers to: the feed rate is equal to the thickness of the rubber, or the feed rate is the amount of one feed in the process of multiple feeds.

Step 3, unscrew the positioning pin 1 and press it into the rubber pad, hold the positioning pin handle 12 with the left hand, rotate the moving knife rest 11 with the right hand and apply pressure downward; in this way, centering on the positioning pin 1, the moving knife rest 11 The distance to the fixed knife rest 10 is the radius, and the circle is drawn. The outer circle of the required rubber pad can be obtained when the movable knife rest 11 rotates one revolution.

Step 4: Adjust the distance between the movable knife rest 11 and the fixed knife rest 10 to make it equal to the inner circle of the required rubber pad; rotate the movable knife rest 11 and apply downward pressure to cut off the inner circle to obtain the desired sealing rubber gasket.

It should be noted that for thinner rubber pads, the operation method of synchronously feeding the cutter and double blades into one molding can be adopted.
