Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, and more particularly to a semi-automatic metal cold-cutting saw. Background Art

[0002] A cold saw is a metal cutting tool primarily used for cutting a variety of materials, including steel, metal, aluminum alloy, stainless steel, and carbon steel. It is widely used in various fields, including industry, firefighting, construction reinforcement, and renovation. The characteristic of a cold saw is its relatively cool cutting process, generating minimal sparks and heat, while also resulting in a smooth, burr-free cut surface, hence the name "cold saw."

[0003] Most cold saws on the market today are push-type. To cut a workpiece, the operator must manually press a switch on the saw handle and then slowly lower the saw blade to complete the cut. This method of operation makes it difficult to cut multiple workpieces simultaneously. For this reason, we offer a semi-automatic metal cold saw.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention. Therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a semi-automatic metal cold cutting saw.

[0006] The semi-automatic metal cold cutting saw provided by the utility model adopts the following technical solutions:

[0007] A semi-automatic metal cold cutting saw includes a frame; a linear guide rail arranged in the frame, a mounting frame slidably arranged on the linear guide rail, a driving component 1 is assembled inside the frame for driving the mounting frame to move linearly on the linear guide rail; a saw blade is arranged on the top of the mounting frame, and a notch is opened on the top of the frame for passing the saw blade, and a driving component 2 is assembled at the bottom of the mounting frame for driving the saw blade to rotate.

[0008] By adopting the above technical solution, the workpiece can be automatically cut off to ensure that the cut edge of the workpiece is smooth and burr-free, and multiple workpieces can be cut off simultaneously.

[0009] Preferably, a shielding cover is installed on the top of the frame at a position relative to the notch.

[0010] Preferably, the first driving member is a cylinder.

[0011] Preferably, the second driving member is a motor.

[0012] Preferably, a pair of limiting mechanisms are provided on the top of the frame, and the limiting mechanisms include a vertical plate fixedly mounted on the top of the frame, an L-shaped plate is mounted on the side of the vertical plate, a pneumatic push rod is slidably mounted on the top of the L-shaped plate, and the output end of the pneumatic push rod is equipped with a rubber pad.

[0013] By adopting the above technical solution, the pneumatic push rod pushes the rubber pad downward, so that the rubber pad moves downward to contact and squeeze the workpiece, thereby fixing the workpiece on the top of the frame.

[0014] Preferably, one of the limiting mechanisms is adjustably mounted on the top of the frame via a movable plate.

[0015] Preferably, the top of the frame is also equipped with a correction block, and the side of the correction block is equipped with an extrusion plate through a push cylinder for extruding and fixing the workpiece.

[0016] Preferably, the correction block is slidably arranged on the top of the frame.

[0017] By adopting the above technical solution, the stability of the workpiece placement can be further increased.

[0018] In summary, the present invention has the following beneficial technical effects:

[0019] The workpiece to be cut (such as iron pipes, steel pipes, rectangular pipes, etc.) is placed and fixed in the notch of the frame, and then the saw blade is driven by the second driving member, and then the mounting frame is pulled to move on the linear guide rail by the first driving member, so that the rotating saw blade moves to contact the workpiece and cuts the workpiece. Through this structural design, the workpiece can be automatically cut to ensure that the incision of the workpiece is smooth and burr-free, and multiple workpieces can be cut simultaneously.

[0020] The above summary is for illustrative purposes only and is not intended to be limiting in any way.

The interior of the frame 1 is equipped with a driving member 4 for driving the mounting frame 3 to move linearly on the linear guide rail 2; a saw blade 5 is arranged at the top of the mounting frame 3, and a notch 6 for passing the saw blade 5 is opened at the top of the frame 1. The saw blade 5 is a cold-cutting saw blade. The bottom of the mounting frame 3 is equipped with a driving member 7 for driving the saw blade 5 to rotate.

[0030] The workpiece to be cut (such as iron pipes, steel pipes, rectangular pipes, etc.) is placed and fixed on the notch 6 of the frame 1, and then the saw blade 5 is driven to work by the driving member 2 7, and then the mounting frame 3 is pulled to move on the linear guide rail 2 by the driving member 1 4, so that the rotating saw blade 5 moves to contact the workpiece and cut the workpiece. Through this structural design, the workpiece can be automatically cut off to ensure that the incision of the workpiece is smooth and burr-free, and multiple workpieces can be cut synchronously.

[0031] Specifically, a shielding cover 8 is installed on the top of the frame 1 relative to the notch 6. By providing the shielding cover 8, flying chips during the cutting process can be shielded to prevent the flying chips from injuring the operator.
