Detailed Description
A metal band sawing machine comprises a base 1, a plurality of rotating wheels (not shown) arranged on the base, an annular chain 7 arranged among the rotating wheels, a saw blade 8 arranged on the annular chain, a support frame 6 fixedly arranged on the base, a saw blade pressing mechanism, a workpiece pressing mechanism and a workpiece positioning mechanism, wherein the base is provided with a feeding abdication port 16, the workpiece pressing mechanism comprises a workpiece pressing cylinder 3 fixedly arranged on the support frame and positioned at the outer side of the saw blade and a workpiece pressing block 2 fixedly arranged at the end part of a piston rod of the workpiece pressing cylinder, the saw blade pressing mechanism comprises two saw blade pressing cylinders 4 arranged on the support frame and positioned at two sides of the feeding abdication port and a saw blade pressing block 5 fixedly arranged at the end part of the piston rod of the saw blade pressing cylinder, and the workpiece positioning mechanism comprises a front screw 11, a rear screw 14, an adjusting sleeve 12 and a positioning baffle 10, the rear end part of the rear screw is fixedly connected with the base, the positioning baffle is fixedly installed at the front end part of the front screw, external threads with opposite rotation directions are respectively arranged on the front screw and the rear screw, the adjusting sleeve is sleeved between the front screw and the rear screw, and internal threads matched with the threads of the front screw and the rear screw are arranged at two ends of the adjusting sleeve.
Furthermore, the inner side of the base is a slope inclined downwards, and the metal strips fall on the base after being cut off and directly fall to the outer end of the base downwards, so that the metal strips are convenient to collect or enter the next procedure.
Further, a pair of horizontal guide rails 15 is fixedly installed on the base, and the two sides of the positioning baffle are connected with the guide rails in a sliding mode through the sliding blocks, so that the positioning baffle can move linearly along the guide rails in the adjusting process, and the operation is more stable and reliable.
Furthermore, a graduated scale 13 is arranged on the guide rail, so that the position of the positioning baffle plate can be conveniently and accurately controlled.
Further, fixed mounting has photoelectric switch 9 on the locating baffle, and photoelectric switch's control end compresses tightly the cylinder and two saw blade through the cable and pushes down the input of cylinder to be connected, and when the material was loaded, the material touched photoelectric switch and stopped the material loading promptly, touched the automatic descending of switch control work piece compression cylinder and two saw blade push down the cylinder, pushed down the chain to compress tightly the material, conveniently saw cut the material and prevent to saw cut the in-process material and remove at will.
When the metal band needs to be sawed, the position of the positioning baffle is adjusted according to the length of the metal band needing to be cut, and the positioning baffle can move inside and outside as long as the adjusting sleeve is rotated, so that the cutting length of the metal band is controlled. Then after the strap passed the feeding of base from the outside of support frame and let the position mouth, the tip withstood locating baffle, the work piece compresses tightly cylinder and two saw blade and pushes down the cylinder and down automatically, and the work piece compresses tightly the cylinder and compresses tightly the material from the material top, prevents to take place the dislocation removal at the in-process of saw cutting, and the saw blade pushes down the cylinder and pushes down the saw blade, and the initiative runner rotation in the motor drive runner, the chain will drive the saw blade and remove, saw cuts to the work piece.
The utility model discloses a metal band sawing machine of protection, because in the course of working, the saw blade is in motion state, and the material is in quiescent condition, has avoided the saw blade to process at same position, and the saw blade wearing and tearing are difficult to the fracture, have reduced the time of shutting down the maintenance and changing the saw blade, and the saw blade is annular saw blade, and machining efficiency is than higher.
Simultaneously because the work piece compresses tightly the setting of cylinder and two saw blades push down the cylinder, the work piece compresses tightly the cylinder and compresses tightly the material from the material top, can prevent to take place the dislocation removal at the in-process material that saw cuts, and the saw blade pushes down the cylinder and pushes down the saw blade, conveniently saw cuts the material, and the setting of level mouth is let in the feeding on the base can prevent that the saw blade from touching the base when being pushed down the cutting.
And because work piece positioning mechanism includes anterior screw rod, rear portion screw rod, adjusting collar and positioning baffle, rear portion screw rod rear end and base fixed connection, positioning baffle fixed mounting is in the preceding tip of anterior screw rod, be equipped with the external screw thread that turns to opposite respectively on anterior screw rod and the rear portion screw rod, adjusting collar suit is in between anterior screw rod and the rear portion screw rod and both ends are equipped with the internal thread with anterior screw rod and rear portion screw rod screw thread assorted, when the length of strap is cut according to needs to the needs, when adjusting positioning baffle's position, as long as twist the adjusting collar can, adjust labour saving and time saving to be convenient for control positioning baffle's position, and can realize the auto-lock, can be dead with the tip of strap top, can not take place to remove the dislocation, make the processing length of strap more.
To sum up, the utility model discloses a strap sawing machine of protection, simple structure, the operation is reliable, need not frequently to change saw blade and scale and adjusts convenient and fast.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
