Problems solved by technology

[0003] The above-mentioned transmission mechanism composed of motor-eccentric wheel-rocking lever-lower rocker arm-connecting rod-upper rocker arm-saw blade holder is quite complicated in structure and shape, and the processing technology is also complicated, the production cost is high, and the working time is relatively high. Loud vibration and loud noise
Jig saws are generally not fixed on the ground. Therefore, the whole machine often shifts due to excessive vibration during work, which is very unsafe.
In addition, the casing mold made of aluminum alloy die-casting is expensive to manufacture, and the material cost is also high

Embodiment 1

[0015] Example 1. A wire-driven jigsaw, as shown in Figures 1-2. It includes a base 1, a casing 2 installed on the base 1, a workbench 3 and a motor 4, upper and lower saw blade holders 5, 6 and saw blades 7 installed in the casing 2 and installed in the base 1 and the casing 2 transmission mechanism. The transmission mechanism consists of a flywheel 8 fixed on the shaft of the motor 4, a small shaft 9 eccentrically fixed on the flywheel 8, a roller 10 set on the small shaft 9, and a long groove 11 set on the roller 10 with left and right arms. The slide block 13 of 12, the guide block 14 fixed on the casing 2 with the left and right guide holes to be respectively sleeved on the left and right arms 12 of the slide block 13, the long steel wire 15 and the short steel wire fixedly connected to the two ends of the slide block 13 respectively 16. The guide wheel set installed on the casing 2, the upper and lower guide rails 23 and 24 with guide grooves installed on the casing 2,...

Embodiment 2

[0018] Example 2. A wire-driven jigsaw, the long steel wire and the short steel wire 16 are both made of steel wire ropes. The left and right arms 14 of the slider 13 are located at the upper end. All the other are with embodiment 1.

[0019] Embodiment 1 and Embodiment 2 have simple structure, good processing technology, small vibration and low noise during operation, and greatly reduce mold cost, material and processing cost. Its overall production cost is only a quarter of what it used to be. It can be widely used in the sawing of thin boards such as wood boards.

Abstract

The steel wire driven scroll saw as one sawing machine includes pedestal, casing, work bench, motor, saw blade holder, saw blade, flywheel fixed on the motor shaft, small axle fixed eccentrically on the flywheel, roller on the small axle, block on the roller and with right and left arms, guide block, long and short steel wires connected to the blocks, guide wheel set on the casing, upper and lower tracks, steel wire tensing mechanism, etc. The guide wheel set includes five wheels; the long and short steel wires are fixed also to the upper and the lower saw blade holders separately; and the casing is made of steel plate through punching. The present invention has simple structure, good machining performance, less noise and low cost, and may be used widely in sawing wood board and other material.

Description

technical field [0001] The invention belongs to the technical field of sawing machinery, and more specifically relates to the design of a wire-driven curve saw. Background technique [0002] The traditional jigsaw consists of a base, a casing fixed on the base, a lower rocker arm and an upper rocker arm installed on the casing, a connecting rod connecting the rear ends of the lower rocker arm and the upper rocker arm, a workbench fixed on the base and The motor, the eccentric wheel installed on the shaft of the motor, the rocker installed between the eccentric wheel and the lower rocker arm with a small shaft, the saw blade holder installed at the front end of the lower rocker arm and the upper rocker arm, and the front end of the upper rocker arm Consists of saw blade tensioner. Its casing is aluminum alloy die-casting. [0003] The above-mentioned transmission mechanism composed of motor-eccentric wheel-rocking lever-lower rocker arm-connecting rod-upper rocker arm-saw b...
