The invention provides a section bar cutting-off machine which is simple in structure and low in cost. The section bar cutting-off machine can cut off a section bar with the size slightly larger than a half of the diameter of a grinding wheel at a time, and the cutting-off efficiency is effectively improved. The section bar cutting-off machine comprises a base, the grinding wheel driven by a driving device, and a section bar fixed support fixed to the base, and is characterized in that the driving device and the grinding wheel are installed on a movable support, a swinging arm is arranged below the movable support, the bottom end of the swinging arm is connected with the base through a first rotating shaft, the swinging arm is further connected with a piston rod of a driving air cylinder through a second rotating shaft, and one end, away from the piston rod, of the driving air cylinder is connected with the base or the section bar fixed support through a third rotating shaft. According to the section bar cutting-off machine, due to the fact that the moving path of the grinding wheel is changed into a curve from a straight line, the section bar cutting-off machine can cut off the section bar with the size slightly larger than a half of the diameter of the grinding wheel at a time, the cutting-off efficiency is effectively improved, and the section bar cutting-off machine has good practicability.
Description
Technical field
The invention belongs to section bar manufacturing technology field, specially refer to a kind of sectional material cutter.
Background technology
At present, section bar has been widely used in building trade and metal structure, and as factory building, bridge, boats and ships, agricultural vehicle manufacture, electric power pylon, Transport Machinery etc., mainly comprise aluminium section bar and shaped steel etc.In process of production, need to cut off section bar according to design, traditional sectional material cutter is only to utilize cylinder or miscellaneous equipment to promote emery wheel according to straight path, there is a problem in this sectional material cutter, a half that is slightly larger than grinding wheel diameter when the size of section bar (is for example said for making the section bar of door pillar, there are two vertical limits, its height or length tend to be greater than half of grinding wheel diameter), just must be according to level, vertical both direction cuts successively, sectional material cutter just must possess the cylinder of horizontal and vertical like this, it is complicated that structure is tending towards, and inefficiency.
Summary of the invention
The object of the invention is to propose a kind of simple in structure, sectional material cutter that cost is low, this kind of sectional material cutter can once cut off half the section bar that size is slightly larger than grinding wheel diameter, effectively improves and cuts off efficiency.
Sectional material cutter of the present invention comprises base, utilizes the emery wheel of drive unit drive, is fixed on the section bar fixed support on base, key is that described drive unit and emery wheel are arranged on a travel(l)ing rest, the below of described travel(l)ing rest is provided with swing arm, and the bottom of described swing arm is connected with base by the first rotating shaft; Described swing arm also drives the piston rod of cylinder to be connected by the second rotating shaft with one, and described driving cylinder is connected with base or section bar fixed support by the 3rd rotating shaft away from one end of piston rod.
When cutting off section bar, utilize and drive the flexible travel(l)ing rest that drives of cylinder piston rod to rotate around the first rotating shaft of its bottom, thereby the travel track that makes emery wheel is curve, expand the area that emery wheel participates in cutting, can be so that the area over half of emery wheel can participate in cutting, make sectional material cutter can once cut off half the section bar that size is slightly larger than grinding wheel diameter, effectively improve and cut off efficiency.
Further, described base is provided with lifting cylinder, vertical guide rail and is movably installed in the lifting support on vertical guide rail, and the piston rod of described lifting cylinder is connected with lifting support, to drive lifting support along vertical guide rail lifting; The bottom of described swing arm is connected with lifting support by the first rotating shaft.By changing the height of lifting support, can change the centrostaltic height of swing arm, the driving cylinder in conjunction with highly constant, can change the travel track of emery wheel, thereby meets different section bar split requirements.
Further, described base is provided with limiting bracket, and described limiting bracket is provided with two positive stop strips, and described swing arm is between two positive stop strips, and described positive stop strip is parallel to the plane at swing arm movement locus place.Positive stop strip can provide certain support to swing arm, avoids swing arm to rock when motion.
Further, described section bar fixed support comprises vertical fixed part and horizontal fixed part, for example, for fixedly having the section bar (saying for making the section bar of door pillar) of knuckle, guarantees fixed effect.
Sectional material cutter of the present invention is simple in structure, easy to operate, by changing the travel track of emery wheel into curve by straight line, make this kind of sectional material cutter can once cut off half the section bar that size is slightly larger than grinding wheel diameter, effectively improve cut-out efficiency, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sectional material cutter of embodiment 1.
Fig. 2 is that the sectional material cutter of embodiment 2 is removed the structural representation after limiting bracket.
Fig. 3 is the structural representation of the sectional material cutter of embodiment 2.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in Figure 1, 2, the sectional material cutter of the present embodiment comprises base 1, utilizes the emery wheel 3 of drive unit 2 drives, is fixed on the section bar fixed support 4 on base 1, described drive unit 2 and emery wheel 3 are arranged on a travel(l)ing rest 5, the below of described travel(l)ing rest 5 is provided with swing arm 6, and the bottom of described swing arm 6 is connected with base 1 by the first rotating shaft 7; Described swing arm 6 also drives the piston rod of cylinder 9 to be connected by the second rotating shaft 8 with one, and described driving cylinder 9 is connected with base 1 by the 3rd rotating shaft 10 away from one end of piston rod.
The top of base 1 is provided with limiting bracket 11, and limiting bracket 11 is provided with two parallel positive stop strips 12, and described swing arm 6 is between two positive stop strips 12, and described positive stop strip 12 is parallel to the plane at swing arm 6 movement locus places.Positive stop strip 12 can provide certain support to swing arm 6, avoids swing arm 6 to rock when motion.
