To carve, craftsmen use different tools, the choice of which depends on the requirements of a particular task. It can be both hand tools and equipment for machine tools. A separate group of such tools is represented by pipe threading die cutters, which differ in structural and ergonomic data.

Design features of electroclipp

If the majority of manual thread-cutting tools are directly involved in the process of creating technological helical ditches, then screw caps can be considered as a machine frame for carvers in the first place. Machining as such is performed by nozzles similar to dies, which are fixed in a special shutter. The movements of the handle transmit torque to the cutter, which contributes to the formation of threads on the pipe. The basic structural elements include faceplates, housing, clamping devices and a fixing bolt. The main material for the manufacture of an electric cutting screwthreads on pipes - high speed steel or carbide alloys. At least the working equipment is made of high-strength metal, but the body is also made of reliable wear-resistant material. Except that plastic alloys can be used for external elements in the form of pads on the handle and holders.

Klupp consumables

Auxiliary materials and accessories for the electric screw plug can be divided into two categories - adjusting and lubricating. Both groups are indispensable and ensure the quality of the tool. Adjustments include wrenches and metric fasteners for adjusting pipe clamp settings. There are both universal devices of this type, and strictly focused on a specific size - as a rule, they are supplied in the basic package.

For smooth running and minimizing friction of the threading screw mechanism, a special oil and grease such as WD-40 is used. Professionals additionally use oil pumps, which increase the productivity of the threading tool. Such devices are equipped with a trigger switch that allows you to precisely control the supply of technical fluid.

Characteristics of a pipe threading die cutter

The tool is characterized by the diameter of the cylindrical workpiece available for processing and the power. It must be emphasized right away that there are models of a universal tool with interchangeable nozzles, and deviceswith a fixed cutting format. For example, a set of pipe threaders can include cutters for 1, 1/2, and 1/4 inch diameters. The tooling in the form of dies also allows the processing of cylindrical studs, eyelets and bolts with a thickness of 4 to 20 mm.

The power potential of the electric motor will also affect the workflow. A standard manual threading die cutter is equipped with an 800-1200 W motor. Professional general-purpose models provide up to 1700 watts. This value will affect the processing intensity. In particular, the average characteristics of the motor provide a threading speed of the order of 20 rpm. It will not be superfluous to take into account the nominal value of the voltage in the network. Typically, such a tool is powered by single-phase 220 V networks with deviations in the range of 15-20 V.

Additional Klupp functionality

High-tech models of electric dies are equipped with electronic stuffing with the ability to start the reverse stroke. This feature is especially useful in machining carbide workpieces, as it prevents damage to the cut due to a shift in the machining direction. Thread quality can also be significantly improved by maintaining a uniform speed.

The stability of the cutter in reverse and forward modes eliminates the risk of defects on the edges. Some models of modern pipe threading die cutters are also provided with a five-axle gearbox with beveled teeth. The presence of this mechanism increases the transfer of force, whichextends tool life and has a positive effect on cutter rotation accuracy.

If the emphasis is on the ergonomics of physical handling, then you should give preference to screw clamps with the ability to place equipment on different sides (left and right). This solution will save time when processing multi-format pipes.

Producers of thread cutting dies

In choosing a tool, a lot depends on the manufacturer. Experienced craftsmen know that the origin of the electroclip determines not only its quality and performance properties, but also the scope of application. For example, for plumbing pipes, it is recommended to use COMPA products or the MATRIX SPARTA range. The price of COMPA CTFE1700WVAL threading screws with diameters 1 and 1/2 is 20-25 thousand rubles. The manufacturer offers a plastic case and all the necessary equipment for adjustment.

Gerat, Rotorica Twistor, REMS and ROTHENBERG models belong to the universal tool. Together with interchangeable heads, the user receives wear-resistant cases and can count on the high quality of the element base. As for the cost, for example, the price of a die cutter for threading Rotorica Twistor pipes with BSPT R 1/2 format nozzles also reaches 25 thousand rubles.

Use of electro-clipp

The presence of an electric drive makes klupp related to machine tools, but retainsergonomics of manual equipment. To create a thread with such a tool, it is necessary to fix the die of the desired format in a special holder, center it and cut it. The user of an electric threading screw is only required to correctly adjust the mechanism for a pipe of the appropriate size and start the engine. Next, die cutters will come into play, which will remove excess metal in rows. The first line of cutters will make a rough cut, and the subsequent ones will make the thread geometry more accurate and accurate. The number of rotational actions is equivalent to the pitch of the coils being formed.

Tips for using the tool

To get the expected result when creating a thread on a pipe and not spoil its shape, the following recommendations from experts will allow:

• Proper pipe preparation. The cleaner the surface that the tool and especially the cutting elements will contact, the higher the likelihood of obtaining a smooth and accurate thread. The same plumbers, in addition to standard stripping and degreasing, advise removing the lead-in chamfer at the end of the pipe.
• Reliable fixation. Not only the workpiece needs to be securely fastened, but also the threading screw, which must also be pre-lubricated with the aforementioned oil. Not only the rigidity of fixation is monitored, but also the correctness of centering. This will avoid burrs when creating threads.
• Removal of excess metal in the course of work. The ejected chips themselves have a negative effect on machining accuracy. Cutting small coils is a very sensitive operation, the quality of which can be reduced even by a grain of sand. Therefore, periodically it is worth doing several reverse rotations, freeing the working surface from technological waste. Again, this will only be possible if there is a reverse stroke on the electric screw.

Feedback on the use of electric screw cap

This carving equipment is used by both professionals and home craftsmen who often have to deal with metal processing. In both cases, the owners note the high cutting speed and ease of handling the tool, since the operator does not need to apply physical force at all. But the most important thing that experts emphasize is the quality of work, which is incomparable with the results from the use of traditional cutters and dies. Moreover, threading dies are in principle capable of processing to large tolerances in length and thickness. But there are also disadvantages to electric plugs. Among them, users highlight the connection to the power grid and the massiveness of the unit. Both of these disadvantages limit the scope. For example, in hard-to-reach places where compact manual equipment without an electric drive can be handled, it is impossible to use a die-cutting screw.

Conclusion

The need for threading arises in a variety of areas, so tools like the electric screw are becoming more common and are actively moving from a professional niche to a household one. Another thing is that infrequent one-time operations forthreading can also be done with models without an electric motor. They are also cheaper. For example, if the average price of a die cutter for threading pipes exceeds 20 thousand rubles, then a simple mechanical analogue with a ratchet can be purchased for 3-4 thousand rubles. However, saving also entails operational restrictions on the use of the cutter, not to mention the low quality of the thread itself with the risk of damage to the workpiece. It should also be borne in mind that in all types and modifications, the klupps can only be used for external processing. Internal threads in pipes are made with taps of a suitable format.
