Description

Technical Field

[0001] The utility model relates to the technical field of circular saw machines, in particular to a circular saw protective device. Background Art

[0002] A circular saw is a toothed tool used to cut steel. A metal circular saw can cut steel as easily as a traditional hose that cuts 2x4's. The circular saw uses a unique material and tooth shape to cut metal faster, has better chip handling capabilities, and does not transfer heat during the cutting process. The circular saw can be used with most professional circular saw machines.

[0003] When cutting, a circular saw will generate a large amount of high-temperature metal debris and sparks, which can easily burn people. If the circular saw blade is not operated properly, it will shatter and fly, causing great harm to people or even endangering their lives. Therefore, the circular saw needs to be protected when cutting steel. The protection method in the prior art is to install the circular saw blade in a box, with entry and exit holes on both sides of the box for placing steel. This method has limitations on the size of the steel to be cut, and when cutting, high-temperature metal debris will still fly out from the gap of the entry and exit holes, and the circular saw blade may also fly out when it shatters, causing danger to people, which needs to be improved. Utility Model Content

[0010] As an improvement, the cutting device comprises a vertical plate fixedly connected to the horizontal plate, a cutting motor is provided on one side of the bottom of the vertical plate, and an output end of the cutting motor passes through the vertical plate and is connected to a circular saw blade.

[0011] As an improvement, a limiting notch is provided on the inner side of the installation groove, and a limiting strip extending into the limiting notch is fixed on the protection strip.

[0012] As an improvement, a limiting block cooperating with the mounting groove is provided on the top of the protection strip.

[0013] As an improvement, the inverted U-shaped frame is provided with a symmetrically arranged polished rod fixedly connected to the collection box, and a circular ring is sleeved on the polished rod, and the circular ring is fixedly connected to the horizontal plate.

[0014] (III) Beneficial effects

[0015] The advantages of the utility model compared with the prior art are:

[0016] 1. The collection box can collect metal debris;

[0017] 2. The inverted U-shaped frame and the protective strip cooperate to block metal debris and broken circular saw blades, causing them to fall from the collection port into the collection box;

[0018] 3. The telescopic rod can drive the cutting device to move up and down to cut steel of different sizes;

[0019] 4. The movable protection strip can stop moving when it contacts the steel material, while the protection strip that is not in contact with the steel material continues to fall to the collection box and stops, thereby reducing the gap between the steel material and the protection strip, and preventing metal debris and broken circular saw blades from flying out of the gap and causing harm to people;

[0020] 5. The light rod can limit the movement of the horizontal plate to make the device more stable. BRIEF DESCRIPTION OF THE DRAWINGS
