Features of the design of the machine CA-2A

The location of the saw shaft relative to the workpieces processed is lower. The filing of the billets is made by four rollers: two lower and two tops. The lower rollers are based on the blanks, the upper - they carry them out to the lower rollers. All rollers are driven, which ensures a stable supply of blanks.

High machine performance is provided by the powerful drive of the saw shaft drive (15 kW) and high feed rates (up to 102 m / min). Unlike other machines of this purpose, Central Asia 2a-1 can cut the hill.

In order to eliminate the vibrations of the saw shaft in the spindle node, a dual radially resistant bearing of increased accuracy is applied; The transmission of rotation to the shaft is carried out by one wide polyclinite belt. Upper roller and presser discs are swing around a fixed axis. They press the workpiece with their own weight, which makes it possible to cut blanks, different in thickness, and hill. All feed rollers and discs are corrugated, which provides feeding even frozen wood.

Excursion to the history of the Central Tsa-2A multi-storage machine (multi-seated Tsa-2a Multi-War Machine)

The Tyumen Machine-Plant, founded in 1899.

Currently, the plant manufactures produces machines of CA-2A-1, CA-2A-2, which are characterized by a more powerful electric motor of a saw shaft and a greater feed rate.

According to the reviews of manufacturing machines of the Tsa-2a series - one of the most reliable domestic circular sawing machines. Until now, applications come to the plant for the supply of spare parts or individual parts instead of worn out for machines that have worked at the production of 25 to 30 years. Such durability is explained by the thoughtfulness of the structure and the high quality of the manufacture of the machine.

Tsa-2a machine tested by time. His predecessor, the machine model of the Central Tsa2, was launched in production in 1973. Since then, he has repeatedly undergraduated with the expansion of technological capabilities and an increase in power. The power of the saw drive was increased during this time from 11 kW to 22 kW, the greatest distance between the extreme saws changed from 50 to 210 mm, instead of six fixed feed speeds, eight was eight, etc.

According to the reviews of the production workers of the Tsa2a series, one of the most reliable domestic circular circular machines. Until now, applications come to the plant for the supply of spare parts or individual parts instead of worn out for machines that have worked at the production of 25 to 30 years. Such durability is explained by the designedness of the structure and the high quality of the manufacturer of the Tsa-2a machine.

Designed for high-performance longitudinal sawmills of edged and unedged boards with a thickness of up to 80 mm on the bars of the desired width.

On the machine you can paint and hill with a drop of their thickness (within one porch) up to 30 mm. At the same time, the hill are fed into the machine with a flat surface down.

• The base of the machine and its bed has a welded and quite rigid construction. The table of the machine is made by a gray cast iron. The housing of the saw shaft, the lower feed rollers and the housing of the upper clamping rollers are mounted on the table, the material of which exits the emerging vibrations. Therefore, the machine has sufficient vibration resistance.
• The saw shaft gets rotation from the electric motor through the polyclinic belt. The use of such a belt instead of a group of classic wedge belts made it possible to reduce the load on the saw shaft and its bearings, reduce vibrations, because The polyclinic belt works more calmly.
• The saw shaft is mounted in bearings, the housings of which are installed on the lower surface of the cast-iron table. Front bearing - radially resistant double high accuracy. It excludes the axial movement of the shaft and provides, among other factors required by the processing accuracy. The rear bearing is also high accuracy. In order to increase the durability of bearings, the replenishment of the lubricant in them through the oils is provided.
• The saws are installed on the cantilever section of the shaft through the key, which eliminates their turn. Between the saws, there are space sleeves, the thickness of which is selected depending on the width of the bars of bars. From the outside of extreme saws, the flanges are installed. The collected panel of the saw is clamped with a special gear nut, which has a thread direction opposite to the direction of rotation of the saw shaft. After the clamp of the package, the nut-gear fell will stop the special screw. All this provides a reliable fastening of saws. A special key for this nut is included in the package of the machine. It makes much easier and accelerates the fastening process saw.
• The lower rollers are made steel to increase their wear resistance. Their length is 350 mm. To improve the clutch of rollers with wood blanks on their outer surface, longitudinal grooves are made. In places of crossing the surfaces of the grooves with the outer surface of the rollers, sharp edges are formed (ripples), which ensures a stable filing of the billets.
  The upper rollers are also made by steel and corrugated - with the same purpose. They are console on the shafts. The latter are installed in bearings in brackets that have the possibility of swing around the stationary axis. These rollers pressed the workpiece to the lower rollers both under the action of their own weight and springs. The adjustment of the upper rollers in height (on the thickness of the sawing blanks) is made by rotating the corresponding flywheel. The countdown of the lift of the rollers is carried out on a special scale.
  All rollers, both lower and upper, get rotation from the electric motor. This ensures a stable billet feed, even in winter conditions.
• Changing the feed rate is performed by switching the rotational speed of the two-speed electric motor and by reinstalling the gear on one of the shafts of the feed mechanism. For this purpose, the machine includes four replaceable gears. They are located on the cantilever sector of the shaft and the change of them takes just a few minutes. The variety of fixed feed speeds allows processing at optimum speed.
• Each of the saws is installed on a single guide knife, which is also included in the package of the machine. When the billet moves, the knives are included in the propuls and additionally provide its rectilinear movement.
• The machine has a guide ruler. It serves to base the sawed cutting boards. The ruler can be reinstalled in the machine, depending on the width of the bar, fixed by the extreme sawpatch (between the saw and a ruler). The width count is carried out on the scale. To adjust the base surface of the line parallel to the saw plane serve as adjusting screws.
• The machine is safe in work. For this, there are special protective devices: two rows of upper safety stops that prevent the release of the workpiece or its unlocked parts towards the machine room; Fences of saws, chain gears, rollers; The dynamic braking system of the drive motor saw, providing a quick stopper saw when the drive from the network is disconnected: Reverse feed - to extract the acute harvesting from the machine (if necessary); Cutting safety pin in the feeding mechanism and others.
• The machine is quite compact due to the fact that the drive saw and the feed drive is located in the bed. As a result, he occupies a little manufacturing area.
