Further, the pressing ram (3) pushes the sliding bars of the hammers (4), thereby pressing the nails into wooden parts (6). The electromechanical actuator comprises a sliding rod (7), a solid part (8) with flanges for mounting to the machine (2) frame and for mounting to a spacer (9) of the drive unit (10).

Description

Technical field

The technical solution relates to a woodworking machine, in particular a machine for nailing wooden parts, which as an exerting force exerting an electromechanical actuator.

BACKGROUND OF THE INVENTION

Currently, mainly hydraulic cylinders are used for shifting the ram for nailing wooden pallets. The device is designed so that under the pressing ram are placed on the guided bar hammers, into which are dosed nails from swinging containers. The nails are then pressed into the nailed parts by pushing the pressing ram. After lifting the press ram, nails are added to the hammers and everything is ready for the next cycle. However, the movement of the ram by means of hydraulics has many drawbacks. The hydraulic system requires frequent checking of oil pressure, tightness and temperature, and hydraulic oil replacement is required every six months. This system is also quite noisy, non-ecological and energy-intensive, since the power is still running on hydraulic power units with power of up to 9 kW.

The essence of the technical solution

The essence of the technical solution is the use of an electromechanical actuator as a part serving to move the pressing ram of the machine for nailing wooden parts. Electromechanical actuators offer a number of advantages over the already mentioned hydraulics. Actuators have quiet operation, high positioning accuracy and reliability, can achieve higher lift speeds and are significantly more energy efficient and also more environmentally friendly. The actuators are driven by 4 kW servomotors. However, they only rotate when the ram is moved, ie the operation of the actuators is not continuous and the energy saving is therefore considerable, when compared to hydraulics it is up to 60%. Location and function of electromechanical actuator, resp. actuators are clearly visible from the attached figures.

The machine is actuated by electromechanical actuators, which exert a force on the pressing ram. The pressing ram then pushes the sliding bars in the hammers and presses the nails into the nailed wooden parts. The hammers are mounted on the guided trapeze.

The actuator consists of a sliding piston rod and a fixed part with flanges for mounting on the machine frame and for mounting the drive adapter clamp. It is also fitted with the adapter of the drive unit and the drive unit itself, eg by the aforementioned servomotor. A ram clamping block with holes for fastening steel screws and steel crescents is secured on the piston rod. The disadvantage of this solution is the higher purchase price than the hydraulic system. However, this disadvantage is compensated by lower operating costs.
