Hydraulic cutting device for cutting a raw aluminum material

A hydraulic cutting device for cutting a raw aluminum material, the hydraulic cutting device comprising:

• a cutting seat having a fixed cutting block securely and immovably mounted inside the cutting seat, a movable cutting block movable relative to the fixed cutting block, and a positioning cylinder mounted beside the fixed cutting block;
• an input track provided on one side of the cutting seat and having first rollers rotatably mounted thereto, a sliding rail mounted on opposite sides of the input track, a fixing seat for supporting the raw aluminum material movably mounted above the sliding rails, a fixing seat cylinder securely mounted under the input track to drive the fixing seat to move along the input track, and an output cylinder mounted under the input track and spaced apart from the fixing seat cylinder to transport the raw aluminum material, the fixing seat including (a) a positioning block, (b) a threaded rod extending out from the fixing seat and having a first free end connected to the positioning block and a second free end connected to a handle so that a position of the positioning block is adjusted by rotation of the handle, and (c) a clamping block connected to a clamping cylinder which is mounted on the cutting seat and disposed opposite to the positioning block such that a raw aluminum material placed on the first rollers is able to be positioned by the positioning block and the clamping block via activation of the handle and the clamping cylinder, the first rollers each being formed with a concave middle portion for receiving the raw aluminum material;
• an output track provided on the other side of the cutting seat and having second rollers rotatably mounted thereto, and a motor mounted under the output track and connected to the second rollers via a chain so that the second rollers are able to be driven by the motor;
• and
• a measuring device mounted on the output track to determine a length of the raw aluminum material to be cut, the measuring device having a pair of parallel guiding rails, a measuring threaded rod extending between the pair of parallel guiding rails, an adjusting handle mounted to a distal end of the measuring threaded rod, an adjusting seat movably mounted relative to the pair of parallel guiding rails and the measuring threaded rod, an arm with two free ends and pivotally mounted on the adjusting seat and provided with a measuring rod mounted on one of the free ends of the arm, and a lifting cylinder mounted on a side of the measuring device and connected to the other free end of the arm so that when the lifting cylinder is activated, the arm is pivoted on the adjusting seat and thus the measuring rod is driven to move accordingly.
