Description

Drilling tool convenient for large-span steel

Technical Field

The utility model relates to a steel processing technology field, concretely relates to big span steel drilling frock of being convenient for.

Background

The steel is a material with certain shape, size and performance, which is made by pressing steel ingots or billets, is an essential important material for national construction and realization of quartification, and has wide application and various varieties, the types of the common steel comprise section steel, steel plates, steel wires and the like, and the section steel can be divided into round steel, square steel, flat steel, hexagonal steel, I-shaped steel, channel steel and the like according to the section shape.

In the mechanical production and processing process of steel, drilling equipment is often required to drill the steel. Conventional drilling equipment is classified into a bench type, a stand type and a radial drilling machine. The radial drilling machine has one rocker capable of rotating around the upright column, and the rocker drives the main shaft box to move vertically along the upright column while the main shaft box moves transversely on the rocker. Therefore, the position of the cutter can be conveniently adjusted during operation to be aligned with the center of the hole to be machined, and the workpiece does not need to be moved for machining. Therefore, the radial drilling machine is suitable for machining heavy large workpieces and porous workpieces. Although, the rocking arm can be rotatory around the stand, the headstock can also make lateral shifting on the rocking arm simultaneously, use the stand as the centre of a circle, the rocking arm is the radius, can obtain the maximum distance that radial drill can carry out the drilling to steel both ends, when the span of steel is greater than the maximum distance of radial drill drilling, it changes the position of steel on the operation panel to transversely stimulate or promote steel usually, the realization makes the adjustment to steel drilling position, in order to compensate the rocking arm and receive steel length restriction, can not directly rotate around the stand through the rocking arm, headstock lateral shifting on the rocking arm adjusts steel drilling position, in order to carry out drilling operation to steel.

Because the shaped steel shape is various to influenced by the steel span, when holing to it, need confirm the pre-drilling position of steel earlier, place steel on the operation panel before radial drill again, through horizontal pulling or promote steel adjust the pre-drilling position of steel and the position of cutter, can have the following condition this moment: firstly, when the contact surface between one end face of the steel and the table top of the operation table is large, the steel and the table top of the operation table have good stability, meanwhile, the friction surface with the operation table is increased, the force is small and the steel cannot be pulled when being pulled, and the pre-drilling position of the steel and the cutter are easy to deviate due to overlarge force, so that the pre-drilling position of the steel or the position of the cutter needs to be adjusted again, and time and labor are wasted (for example, channel steel and flat steel). When the contact surface of one end face of the steel material and the table top of the operation table is small, although the friction surface is reduced, the steel material is convenient to pull, the steel material is easy to rotate (such as round steel) during transverse movement, so that the pre-drilling position of the steel material and the cutter are offset, and the pre-drilling position of the steel material or the position of the cutter needs to be adjusted again. Third, through add rotatable roller on the operation panel, change the face contact into point or line contact, conveniently remove steel like this and compare laborsaving, nevertheless not stable enough when steel is placed on the operation panel to can lead to steel when lateral shifting or to its drilling, the pre-drilling position of steel can produce the skew with the cutter. No matter the contact surface of steel and operation panel is big or small, when placing steel on the operation panel or removing steel at every turn, all need the position of the preliminary drilling position of adjustment steel or cutter, make both can not produce the skew to increase the drilling degree of difficulty, thereby bring the inconvenience.
