Guillotine for metal with their own hands

Guillotines are devices that are designed for cutting metal sheets. The limiting thickness depends on the power of the model. To date, the most popular are the hydraulic modifications. However, in the market you can also find manual models that are able to work with a sheet of metal of small thickness.

The main element of the device is considered to be knives. By structure, shape and angle of inclination, they can vary quite a lot. It should also be mentioned that the guillotine can be operated with a hand or foot device. To make this tool yourself, you need to familiarize yourself with the most common modifications and understand their differences.

Model with ball guides

Gathered this type of guillotine for metal with their own hands from the installation of the frame. To do this, use two sheets of metal. Cast iron in this case is ideal. After that, a platform is prepared for work with the workpiece. Control units can be used in a variety of ways. The engine is used most often with a power of about 3 kW. However, in this situation, much depends on the thickness of the metal.

After fixing the platform, you can go directly to the installation of ball rails. You can buy them in the store without any problems. The next step is to fix the upper beam. On it should be fixed knives, which will produce metal cutting. Fasten them on a special plate. It, in turn, is obliged to connect with the pressing mechanism. After installing the motor, the torque must be transmitted through the central crankshaft. You can do this if you install the gear.

Device with hydraulic guides

As a rule, with technical guillotines for metal cutting, the technical characteristics are as follows: nominal power - 3 kW, limiting frequency - at 42 Hz. Assembly of the device begins as standard with the installation of the frame. At this stage, many experts recommend parallel to each other to fix two sheets of metal.

After that, you will be able to install a platform on which you can work with the workpiece. Mount the hydraulic guides on the motor side. In this case, the control unit may be placed on the other side. The electric motor is more conveniently fixed from the bottom of the frame. All this will hide the wiring and do not spend a lot of time on isolation. The upper beam is assembled primarily with the installation of side supports. Only after this, knives are connected to the pressing device.

Model with rear stop

It is done with the rear end of the guillotine for metal with its own hands quite simply. First you need to tackle the bed. In this case, it is possible to use cast iron. The upper platform must be adjusted to fit it. After this, it will be possible to fix the upper beam. Directly the rear retainer should be installed only after the knives. In addition, it is possible to use hydraulic guides. In this case, much depends on the type of pressing device. If it is small, then the side racks can be made narrow. Otherwise, they will have to be expanded for convenience.

Device with front stop

The manual guillotine for metal with the front stop to this day is very in demand. For the assembly of such a device, the frame with the frame is first installed. The control is most often suitable for the specified modifications of the foot type. By the size of the working area, the presented devices can vary greatly. In this case, much depends on the strength of the frame. The electric motor for normal operation of the guillotine is more expedient to choose with a power level of 3 kW and a limiting frequency of about 33 Hz.

The height of the upper beam can be different. However, the knife plate for a knife must have a narrow guillotine for metal. Many experts recommend it to install at an angle of 3 degrees. Due to this, metal cutting will occur quite qualitatively. The forward stop should be fixed on the steel pulley. For this purpose, you need to use a welding inverter.

Modifications with feed mechanism

A guillotine for metal (tabletop) of this type nowadays occurs quite often. Such modifications are most suitable for wide production. It should also be taken into account that the feed mechanism can be installed in different ways. However, the work on assembling the guillotine always begins with the mounting of the frame. After that, the frame with side supports is fixed. The next step is to install the motor to the device.

To do this, it is important to weld a platform over the bed, on which it can be located. The feed mechanism should be manufactured from the installation of the central shaft. After that, a special sealant is selected, on which the workpiece will be placed. The next step is to install the rollers along which the tape will move. All this must be connected to the central crankshaft. Many specialists use side gears. Then, to assemble the guillotine, it will only be necessary to weld the upper beam with the knives.

Device with blade adjuster

A homemade metal guillotine with a blade adjuster is a sought-after design. You can begin assembling the device from the bottom frame. After that, it will be possible to create a platform for future procurement. Directly adjust the blades should be located on the upper beam. For this, the side stops are first installed. They do not need a lot of height. In this case, much depends on the size of the frame. After fixing the side supports, you can proceed to fixing the plate directly to the blade.

In this case, the pressing devices can be used differently. To change the position of the blades it is necessary to weld a special bolt to the upper beam. In addition, you will need to install a lock to secure the blades in a certain position. After this, it is necessary to tighten the screw, with which it will be possible to change the width of the gap. To do this, you will need to use a wrench. In order for the guillotine to work for a long time, it is important to periodically give time to service the adjustment mechanism. For this purpose, many experts recommend lubricating the side bolts with machine oil. Directly work on the guillotine for metal can be carried out by pressing the pedal.

Modifications with a movable bed

The guillotine for metal (hydraulic) with a movable bed is rather complicated. In this case, much depends on the weight of the frame. Use for this purpose is more appropriate steel billets. First of all, the side racks are installed. After this, it is possible to make the lower supports. The upper beam in this case is installed last. After fixing the lower supports, you must proceed to mount the motor. Directly the position of the bed must be changed through the central crankshaft. For this, two gears are mounted on the side supports. Their diameter must be at least 35 cm. Further it is important to fix the central shaft.

To do this, you need to use a welding inverter. The next step is fixing the tape. Thus, the torque from the electric motor will be transmitted to the side gears. Next, you need to estimate the height of the frame. To the frame never flew from it, it is necessary to install the latches. For this purpose, it is more appropriate to reuse the welding inverter. At this stage, care must be taken not to block the working area with the latches.

2 kW device

The guillotine for cutting metal by 2 kW allows you to actively deal with sheets with a thickness of up to 2 mm. In some cases, feeding mechanisms are installed. Blades are most often used hardened and are located at an angle of 2 degrees. In terms of dimensions, these devices are very compact. The height of the upper beam they do not exceed 20 cm. Also note that due to the low power of the electric motor, the central crankshafts are set to a diameter of up to 3 cm. Otherwise, a large pressure is applied to the blade plate, which can lead to breakage of the guillotine.

Modification of 3 kW

Guillotine for metal at 3 kW limit frequency can boast at 35 Hz. It should also be noted that the models are able to work with blanks, the thickness of which does not exceed 3 mm. Most often they are used for cutting steel plates. In this case, you can use both galvanized and stainless material. The walls of such devices, as a rule, are wide. Control units can be used in a variety of ways.

Due to the large dimensions, the frames are designed with lateral stops. At the same fixators on the platform must be on both sides. The height of the upper beam is approximately 40 cm on average. The blades in this case are usually set hardened at an angle of 3 degrees. Feeding mechanisms for such models are the most suitable hydraulic type.

Device with E10 controller

A metal guillotine with a controller of this type is operated by a hydraulic system. Assembly of the mechanism is important to begin with fixing the frame. Directly the controller can be installed only after the electric motor. At the same time with the switch it must be connected. To connect the controller to the hydraulic device you will need to use a soldering iron. The advantage of this unit is that it allows you to change the power of the guillotine. At the same time, failures occur quite rarely.

Application of the controller E15

A guillotine for metal with controllers of this type is quite common. From the previous modification, the models differ in their multifunctionality. The electric motor power in this case is adjusted more precisely. In this regard, it is possible to work with metals of different thicknesses. With a switch, this device must be connected directly. Also, you will need to use a blowtorch to connect the controller to the control unit.
