Device for changing the saw blade on a circular saw machine

A device (1) for changing the saw blade (2) on a circular saw machine with a detachably fastened saw blade (2) has at least one gripper (8) for taking hold of a loose flange (5) on which the saw blade (2) is located and held, this gripper permitting a guided movement of the saw blade (2) from and to the fixed flange (3). In this arrangement, it is advantageous if the device (1) has a driven screw driving means for releasing and/or tightening a fastening screw (4) between the loose flange (5) and a fixed flange (3) so that the release and fastening of the saw blade (2) can also be mechanised. The device (1) thus permits refinements if, for example, two grippers (8) are provided which accelerate the changing of the saw blade and automate the changing when an appropriate control system is used.

FIREWOOD SAWING APPARATUS

FIREWOOD SAWING APPARATUS Abstract of the Disclosure Logs which have previously been de-limbed are placed onto and removed from a loading deck one at a time and delivered to an aligning trough or mechanism where one end of all logs are moved to a common point. The logs are then conveyed one at a time by a feed conveyor in a direction transverse to the longitudinal axis of the logs and presented to a sawing mechanism where each log is sawed simultaneously into a plurality of shorter firewood pieces. The sawing mechanism includes a plurality of circular saws spaced longitudinally along a common axis which is, in turn, spaced above the level of the feed conveyor and extends parallel to the longitudinal axis of the logs. Each saw is individually mounted for ease of removal and adjustment. A spring device urges the log downwardly, while lugs on the feed conveyor at the same time urge the log forwardly through the sawing mechanism.

LARGE DIAMETER TRAVELLING PIPE CUTTER

According to an aspect of the present disclosure, a low profile travelling pipe cutter (100) is provided which is adapted to perform at least one of cutting and beveling a hollow vessel (120) while traveling around the vessel using a cutting tool (120, 270) mounted thereon. The pipe cutter includes inner and outer carriages, a capstan assembly (130) attached to the outer carriage (138) to which a feed cable (252) is attached, and rollers attached to the outer carriage (138) to which a tension cable (250) is attached. The force adjustment assembly (140) changes the vertical position of the outer carriage (138) relative to the inner carriage (134, 136) to compensate for the pipe cutter going inwardly and outwardly as it travels around a hollow vessel (120) in order to maintain constant pressure caused by the lever tension interface (1307). A guard assembly (134) is provided for covering and uncovering the cutting tool (120, 270) during cutting.

A TOOL DEVICE

The invention relates to a tool device which is suitable for use with an, in particular hand-held, machine tool, having a drive device moving, in particular in oscillating fashion, about a drive axis. The tool device has a connection device which allows it to be fastened on a machine tool such that its drive axis and an axis of rotation of the tool substantially coincide. The connection device, for absorbing drive power, has at least two drive-surface regions, which are spaced apart from said axis of rotation of the tool and each have a multiplicity of surface-area points. Planes tangential to said surface-area points are inclined in relation to an axial plane which encloses the axis of rotation of the tool. Furthermore, said tangential planes are inclined in relation to a radial plane which extends perpendicularly to the axis of rotation of the tool. This means that the torque introduced into the tool device by the machine tool, via the drive device, is reliably absorbed.

WORKING ACCESSORY THAT CAN BE ACCOUPLED WITH MULTIPLE TREE BOLTS

Tool device

The invention relates to a tool device which is suitable for use with a machine tool, in particular a hand guided machine tool, having a driving device moving, in particular in an oscillating manner, around a driving axis. The tool device has an attachment device which allows it to be fastened on a machine tool such that its driving axis and an axis of rotation of the tool substantially coincide. The attachment device, for absorbing the driving force, has at least two driving area regions, which are spaced apart from said tool axis of rotation and each has a plurality of surface points. The tangent planes to said surface-area points are inclined in regard to an axial plane, which encloses the tool axis of rotation. Furthermore, said tangent planes are inclined regard to a radial plane which extends perpendicularly to the tool axis of rotation. This means that the torque introduced into the tool device by the machine tool, via the driving device, is reliably absorbed.

Cutting machine with double saw blades

Abstract of the description The present utility model relates to a twin saw blade cutter, improves upon the existing foundation of inner and outer saw blades, small and large output shafts, first and second gearwheels and a power gear shaft, etc., in that the small output shaft is designed with a first annular locking groove and a second annular locking groove located between the first and second gearwheels, a first locking spring which presses against a fifth bearing is mounted in the first annular locking groove, a second locking spring is mounted in the second annular locking groove, and at the same time a flexible piece which arches towards the side of the second locking spring is further sleeved on the small output shaft, the two ends of the flexible piece pressing against the second gearwheel and the second locking spring respectively. After adopting the above solution, it is possible to not only prevent outward protrusion of the small output shaft, but also prevent retraction of the small output shaft, and at the same time absorb the cumulative manufacturing tolerance of the various components and preload the small output shaft in the axial direction, thereby ensuring coincidence of the axial positions of the two shafts such that the inner saw blade has a limited amount of space for sliding movement left and right, and ensuring that there is an appropriate gap between the two saw blades at all times, such that the cutting operation may proceed smoothly and reliably.

Drill electric motion saw

본 고안은 드릴에 간편하게 부착하여 사용할 수 있도록 한 드릴 전동톱에 관한 것이다. The present invention relates to a drill chainsaw that can be easily attached and used on the drill. 종래의 전동톱은 고정식 톱과 휴대용 톱이 있는데, 고정식톱은 부피가 커 대부분 목공소나 제제소와 같은 곳에서 사용하므로 가정에서 사용하기는 부적합하고, 휴대용톱은 톱날이 체인구조로 되어 있어 이를 제조하기가 어렵고 또 엔진 및 엔진을 구동시키는 장치들이 복잡하며 또 휴대용톱에는 절단선을 따라 톱을 안내하는 안내수단이 없어 정밀한 절단작업에는 부적합함은 물론 제품의 가격이 고가이므로 가정에서는 사용하기가 부적합하다. Conventional chainsaws have a fixed saw and a portable saw, the fixed saw is large and bulky used in places such as woodworking shops or mills are not suitable for use at home, the portable saw is a chain saw saw blade manufacturing it It is difficult to do, the engine and the devices that drive the engine are complicated, and the portable saw does not have a guide means for guiding the saw along the cutting line, which makes it unsuitable for precise cutting work and the high price of the product. Do. 본 고안의 드릴 전동톱은 구조가 간단하고 천공작업에 사용되는 드릴(10)에 간단히 부착하여 드릴(10)의 동력으로 회전톱날(20)을 회전시켜 절단물을 절단하기 때문에 가격이 저렴하고 조작이 간편하여 일반가정에서 쉽게 구입하여 사용함은 물론 편리하게 사용할 수 있다. 그리고 길이조절이 가능한 가이드(31) 및 지지판(29)이 설치되어 있어 이를 이용하여 절단두께나 회전톱날(20)의 각도를 정확하게 유지할 수 있으므로 누구나 정밀한 절단작업을 할 수가 있는 장점이 있다. The drill chain saw of the present invention has a simple structure and is easily attached to the drill 10 used for drilling, thereby rotating the rotary saw blade 20 with the power of the drill 10 to cut the cuttings, and thus the price is inexpensive and operation. This simple, easy to buy and use at home as well as convenient to use. In addition, the length of the guide 31 and the support plate 29 is adjustable, so that the cutting thickness or the angle of the rotary saw blade 20 can be accurately maintained by using the same, so anyone can make precise cutting work.
