Design of drilling machine 2118

By its design, the drilling machine is very easy to control. In order to establish the selected drilling speed, it is necessary to rearrange the wedge-shaft to the appropriate pulley stage.

In order to transfer the belt from one step of the pulley to another, it is necessary to unscrew the special handle on the bracket and by turning the screw to the left to submit the bracket together with the electric motor. After that, it is necessary to rearrange the belt, and then (for belt tension) by turning the screw to the right to move the bracket with the electromotor from itself.

Automatic feed is carried out through the feed box, the roller of the latter is rotated from the spindle vapor through a small gearbox, which is connected to the straphek belt.

The magnitude of the automatic feed is 0.2 mm per spindle turnover. Feed more than 0.2 mm. You can only manually implement, for which a special overtaking mechanism is arranged in the feed box.

In order to work with a feed of less than 0.2 mm (when drilling along steel to Ø 6 mm), the automatic feed must be turned off by removing the handle counterclockwise to the failure and on the side of the disk to complete the thrust screw.

In order to automatically be drilled to a given depth, there is a mobile stubborn strap on the disk, and a special scale in millimeters is applied on a sniped ring around the circle, along which the specified depth is counted. Setting the bar is made in accordance with the required depth of drilling.

Starting and stopping the machine is made using an electric motor, and the latter is turned on and off from the drum switch.

Automatic feed 0.2 mm. It can be applied to carbon steel, for drilling diameters from Ø 6 mm to 18 mm. For cast iron, for drilling diameters from 3 mm. up to 18 mm.

When operating an automatic feed, the handle must be installed in the middle position.

The ease of turning off the automatic feed is carried out by selecting the rollers in the feed box: Ø 12,3..12.7.

Cooling drilling machine 2118

To cool the tool when drilling, a special P22-A electric pump is mounted on the machine, which can be turned on using a separate batch switch.

For coolant in the machine, a special reservoir is provided in the machine.

Lubricant drilling machine 2118

The machine lubricant is made daily before starting work in the following places:

The axis of the feed gear - through two oils on the body of the feed box.

With an automatic feed, it is necessary to richly lubricate the neck of the feed box feed roller - through a circular chamfer in the sleeve of the feed box.

All other mechanisms are lubricated periodically by packing taving through the hole specifically provided for this purpose.

The lubrication of the bearing of the labets is performed periodically by unscrewing the roller from the plank (left thread). The lubrication of the feed roller bearings is carried out through the hole in the gear Z63, for which the locking screw is turned.

It is necessary to lubricate the gearbox gears daily.

Lubrication of the rush gearing box of the feed is made by supplying oil to the penoli teeth.

The axis of the worm gear in the table lifting mechanism is lubricated through the insulating on the axis end.

Technical characteristics of the machine 2118

Vertical machinery 2118; 2135; 2150. Drill head with various tools.

Vertical vertical machines 2118; 2135; 2150 are used when drilling holes with a diameter of up to 50 mm.

The first two digits show the type of machine, and the latter is the largest diameter of drilling.

In fig. 129 shows the monoschpindel vertical drilling machine 2150 and its kinematic scheme. It consists of a single-column vertical bed 1 fortified on foundation Plate 2. An electric motor is installed on the bed, the speeds of the speeds and the box of feed 4, with which spindle 5 receives six speeds from 46 to 475 rpm and ten feeds from 0.15 to 0.30 mm per revolution.

Details when drilling are installed and fixed on the table 6. Drill 7 in this machine can be manually carried out with steering wheel 8 or automatically using the speeds and box box. Rises and falls the table with the rotation of the handle 9. The machine is turned on using the buttons stirred on the shield.

The drilling heads are often installed on the spindle of vertical-powered machines (Fig. 130), allowing the drilling with five tools for one form, such as drilling, thread cutting, deployment. Thus, a monoschpindel machine with such a head can replace five-spindle, but the part does not need to be rearranged.

Drilling of metal

Vertical drilling machine model 2118

You have already met the device of the drilling machine NS-12. On such machines you can drill a hole with the largest diameter 12 mm. But in some cases we need holes a much larger diameter. In this case, drill on more powerful machines. We will meet one of these machines now. This is a vertically drilling machine model 2118.

It consists of base, columns, velocity boxes, guide bracket, in which the feed mechanism and spindle node are mounted, and the table. Copper box with an electric motor installed on the top of the column.

Metal different hardness are processed when different speeds. The speed of rotation of the drill is selected taking into account its material and diameter. Procedure for setting machines different design At the desired speed different. Thus, on the desktop drilling machines of the NS-12, the speed changes by moving the belt from one step of the pulley to another. The boring machine 2118 switches the handles of gear wheels in the speed box.

When drilling, the tool and billet are heated. Try to quickly lose your palms about each other.

Senake heat? The same thing happens with the drill. But only the tool heats up very much. The hot drill is quickly stuffed, the metal cuts poorly. So that this does not happen, while working the tool is cooled with a special fluid: soapy and soda water, oil emulsions. At the same time, the hot drill gives part of the heat of the liquid and cools, and the liquid heats up. Therefore, the base of the machine is made hollow and serves both the tank for collecting the coolant.

Details when drilling are installed on a table that can rise and descend with a special handle. Remember! Little holes are better drilled at high speed, and the holes of a large diameter - on a small one.

The vertical drilling machine 2N118 is a universal unit, its power is striking specialists and fans of accurate drilling.

The boring machine 2N118 is designed for such actions such as drilling, cencing, deploying holes, as well as cutting the ends of the parts, subject to the use of a special nozzle.

The main sphere of use is the enterprises of the middle and small profile, where products are produced in small batches. Forgery of equipment - Massown MSZ factory, Republic of Belarus.

When carrying out a drilling operation, the rotational movement of the head and spindle on a moving basis is carried out. As you can see, the mechanism is quite simple, nothing superfluous. When determining drilling parameters, indicators of drilling diameter are taken into account, the length of the spindle itself.
