the usage mode is that when the band saw is pressed down, the ruler pressing strip (219) is adjusted to the outermost edge of the cut pipe body, namely as shown in fig. 11, when the band saw is pressed down for cutting, the outer saw band strip cannot deform because the sudden bottom of the outer saw band strip does not abut against a pressed object;
the right-side guide structure is described, and in the prior art, as shown in fig. 1-2, the power structure is arranged on the right side and drives the saw band to rotate clockwise, that is, when the saw band is led out from the right-side saw blade outlet window (3), the transmission is active transmission, the speed is high, and the vibration of the saw band is much larger than that of the left-side passive transmission; the structure of the guide body on the right side is needed, because the saw band is twisted too much due to pressing down in long-term use, a structure with a tidying and straight guide structure is arranged, as shown in figures 5-8, the right seat (207) comprises two objects, namely a right tidying head (13) and an anti-collapse head (209), wherein the right seat (207) is a mirror image of a tidying head (212) with the same structure of the left seat (206), the right tidying head and the anti-collapse head can be integrally shaped or can be separately assembled as shown in figures 5-6, if the structure is a separately assembled structure, the guide structure can be used only for tidying, only the separate assembled structure is recommended to be used, an upper split connecting plate (210) is arranged obliquely upwards at the head ends of the tidying head (212) and the right tidying head (213), an upper split connecting plate (210) is arranged obliquely upwards at the head end of the anti-collapse head (209), and the positions of the grooves of the lower split connecting plate (211) and the upper split connecting plate (210) are matched with each other, the upper splicing connecting plate (10) and the lower splicing connecting plate (211) are spliced with each other to complete connection; then the following structure is used for fixing the connection suspension structure with screws from bottom to top: lower amalgamation connecting plate (211) set up the screw and adopt screw and suspension board (204) to connect, go up amalgamation connecting plate (210) and set up the screw and adopt screw and suspension board (204) to connect or right reason take head (213) and prevent collapsing head (209) amalgamation back, adopt the screw to fix amalgamation last amalgamation connecting plate (210) and lower amalgamation connecting plate (211) at suspension board (204) and connect. The using effect of the right band tidying head (213) is the same as that of the band tidying head (without a telescopic pressure bar) of the left seat (206) of the machine body, but the effect is different after the combined anti-collapse head (209) is combined, and in most use conditions during cutting, a cut pipe body is placed on the right side as far as possible, so that the right band saw is stressed too much because the pipe body is obliquely cut and is not directly and flatly cut from bottom to bottom, and a very firm upward-pressing structure is needed for preventing collapse teeth and guiding, and a height difference is formed after the right seat (7) is stacked as shown in figures 3-4, so that a pressing (guiding) straight structure can be provided for the arc-shaped band saw just led out from the right band outlet window (3).
Preferably, the transverse section of the right belt tidying head (213) is L-shaped and comprises a vertical block (213) and a transverse block (214), the vertical block (213) and the transverse block (214) are vertically arranged, two groups of belt guide pulleys (215) are arranged at the bottom of the vertical block (213), the belt guide pulleys (213) are arranged in parallel in the front and at the back, the distance is equal to the thickness of a belt saw blade, a top guide wheel hole (216) is arranged in a hollow manner in the transverse position between the two belt guide pulleys (213) in the body of the transverse block (214), a top guide wheel (217) is suspended in the top guide wheel hole (16), and a lower split connecting plate (211) is obliquely arranged. The right tape managing head (13) mainly needs 2 structures, 1 can extend outwards but needs the extending structure to be firmer, so that the tape managing head is provided with 1 assembling structure to be assembled with the tape managing head, and the block structure is firm and has strong stress resistance.
Preferably, the strip arranging head (212) is of an integrally molded block structure in a vertical L shape, and comprises a transversely arranged head table block (222) and an upper splicing connecting plate (10) obliquely arranged backwards above the head table block (222), two groups of guide belt pulleys (215) are arranged at the bottom of the head table block (22), the front and the back of each guide belt pulley (213) are arranged side by side, the distance is equal to the thickness of a band saw blade, a top guide wheel hole (16) is arranged in the transverse position of a body of a transverse block (14) between the two guide belt pulleys (213) in a hollow mode, and a top guide wheel (217) is suspended in the top guide wheel hole (216). The tape-arranging heads (212) can be used singly, or can be combined with the right tape-arranging head (213) for splicing and then used, and the right tape-arranging head (213) can also be used singly, but the effects of the two single use are not very good.
Preferably, the right seat (207) is provided with 1 ribbon tidying head (212) and 1 right ribbon tidying head (213) which are combined for use. In combination with the above preference, this combination is the best use, since it prevents rapid vibrations in the transmission section (i.e. on the side where the motor is located on the right) and also corrects if the blade is deformed, while the passive end (on the left where the motor is not located) only needs to be corrected normally.
The above description is only for the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be covered within the protection scope of the present invention.
