[0020] A use method of a bench saw applied to steel pipe production, comprising the following steps:

[0021] S1, first, the steel pipes to be cut are stored in the storage rack for automatic feeding;

[0022] S2, then, the jacking cylinder is started to lower the inclined plate and the resisting plate to the bottom end, at this time, the steel pipes located at the edge directly roll onto the inclined plate, and the remaining steel pipes are temporarily retained in the storage rack by the pressing block;

[0023] S3, the jacking cylinder is started again to raise the inclined plate and the resisting plate to the highest end, at this time, the steel pipes roll onto the plurality of L-shaped supporting plates for temporary support;

[0024] S4, the jacking cylinder is started again to lower the inclined plate and the resisting plate to the bottom end, at this time, the L-shaped supporting plates send the steel pipes into the chute, and the steel pipes in the storage rack are supplemented to the inclined plate again;

[0025] S5, the servo motor is started to drive the positioning block to slide, and the steel pipe is pushed to move and matched with the resisting block to complete the clamping of both ends of the steel pipe;

[0026] S6, then, the lifting cylinder and the driving motor are started at the same time to drive the high-speed rotating circular saw blade to move downward to complete the cutting of the steel pipe;

[0027] S7. Finally, the cut steel pipes roll down the discharge port into the collection box for centralized collection.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. The table-type saw disclosed in this invention, applied to steel pipe production, drives the positioning block to move by starting the servo motor, and pushes one end of the steel pipe to move. When the other end of the steel pipe abuts against the stop block, the servo motor is turned off, and the positioning and clamping of the steel pipe is completed. The positioning length of the steel pipe can be adjusted by rotating the adjusting screw to drive the stop block to move, so as to facilitate the cutting of different lengths.

[0030] 2. The table-type saw disclosed in this invention, applied to steel pipe production, moves the horizontal plate up and down by activating the lifting cylinder, which simultaneously moves the back plate and the inclined plate up and down. When the back plate and the inclined plate move to the bottom, the steel pipe located in the frame can roll down onto the inclined plate through the opening, and the steel pipe is stored by cooperating with the bed body. When the back plate and the inclined plate move to the top, the steel pipe located on the inclined plate is released from the bed body's resistance limit and can fall directly into the inclined groove, achieving the effect of automatic feeding.

[0031] 3. The table-type saw disclosed in this invention, applied to steel pipe production, moves the horizontal plate upward, simultaneously moving the L-shaped top plate upward, and the vertical rod moves the L-shaped support plate upward. When the inclined plate reaches its highest point, the L-shaped support plate is flush with the top of the machine body. At this point, the steel pipe on the inclined plate can roll down the edge of the machine body onto multiple L-shaped support plates, where multiple arc-shaped grooves provide limiting support for the steel pipe. Then, the lifting cylinder is activated again to move the inclined plate and L-shaped top plate downward to reset, while the vertical rod moves the L-shaped support plate downward to reset. When the L-shaped support plate is fully inserted into the chute, the steel pipe will automatically roll downward along the inclined surface of the chute. The downward movement of the steel pipe supported by the L-shaped support plate prevents the steel pipe from falling automatically, effectively improving the positioning accuracy of the steel pipe.

[0032] 4. The table-type saw disclosed in this invention, applied to steel pipe production, uses a pressure block and a spring to compress the steel pipes located within the frame. Only the outermost steel pipes can roll down onto the inclined plate through the opening, while the remaining pipes are confined within the frame to prevent excess pipes from rolling down. When the lifting cylinder is activated, the inclined plate and the stop plate move upwards. Simultaneously, the triangular block and the fixing rod move the long plate upwards, which in turn moves the sleeve and inner rod upwards via the support rod. Finally, the pressure block moves upwards and releases its pressure on the steel pipe, allowing it to roll down and be stopped by the stop plate. When the inclined plate and the stop plate move downwards again to the bottom, the pressure block again compresses and limits the steel pipe. After rolling down to the outermost edge and releasing the stop plate, the pipe rolls back onto the inclined plate. This process is repeated to complete the automatic feeding.

[0033] 5. The table-type saw disclosed in this invention, applied to steel pipe production, involves a lifting cylinder that moves the mounting plate downwards. Simultaneously, the circular saw blade moves downwards to cut the steel pipe, and the mounting plate moves the vertical plate downwards. At this point, a pull rope can be used to pull the baffle upwards, making it vertical. After the steel pipe is cut, its downward rolling motion is first blocked by the baffle, preventing excessive speed. After cutting, the lifting cylinder is activated again to move the mounting plate upwards to reset, and the vertical plate moves upwards as well. At this point, the baffle automatically flips downwards to reset due to its own weight and the pressure of the steel pipe. Once the baffle flips into the slot, the obstruction to the steel pipe disappears, and it continues to roll downwards into the collection box, preventing damage to the steel pipe due to excessive speed.

[0034] This invention uses a storage rack to store steel pipes and utilizes the cooperation of a feeding mechanism and a pressing mechanism to automatically feed the steel pipes. At the same time, it uses the cooperation of a positioning block and a stop block to automatically position the steel pipes and achieve fixed-length cutting of the steel pipes. The whole process can save a lot of manual labor, is simple to operate, and has a high degree of intelligence.
