Description

TECHNICAL FIELD

[0001] The utility model relates to a steel bar cutting machine technical field, concretely is steel bar cutting machine. BACKGROUND

[0002] In the steel bar processing industry, the steel bar cutting machine is one of indispensable equipment, and it is mainly used for cutting the steel bar into the required length.

[0003] The steel bar cutting machine cutter head widely used in the market is mostly designed as one-way cutting, that is, the cutter head can only cut from one side of the steel bar. Since the cutter head only applies cutting force from one direction, the steel bar is only extruded and cut by one point during the cutting process. This cutting method often leads to the flat or inclined surface of the cut steel bar, which cannot achieve the ideal vertical or flat surface effect. The uneven surface not only affects the appearance of the steel bar, but also may affect the mechanical properties and subsequent processing quality of the steel bar.

[0004] Therefore, the steel bar cut by one-way cutting often needs secondary processing, such as grinding or milling, to correct the cross-sectional shape, so as to meet the subsequent use requirements, which not only increases the processing cost, but also reduces the production efficiency.

[0039] Need to explain is: the existence of baffle 25 can also increase the strength of connecting rod one 22, and in the cutting process, connecting rod one 22 will receive greater pressure and impact force, and the design of baffle 25 can disperse these forces, reduce the stress concentration of connecting rod one 22, to prolong its service life.

[0040] ​Working principle: when the driving motor is started, the lower roller 5 starts to rotate, and the steel bar is sent to the space between the lower roller 5 and the upper roller 4. The lower roller 5 drives the steel bar to move forward, while the upper roller 4 is pressed down by its own weight to ensure that the steel bar does not move left and right during cutting. At this time, the rotating motor 32 is started, which drives the rotating disc 8 to rotate, and through the transmission of connecting rod two 27 and connecting column two 28, the main pressing plate 10 moves up and down reciprocally. However, at this stage, the main pressing plate 10 does not directly contact the driven pressing plate 29. With the continuous advancement of the steel bar, the head of the steel bar will contact the connecting rod one 22 and push it, so that the connecting rod one 22 is inclined downward. The fixed column one 23 at the top of the connecting rod one 22 drives the moving rod 19 to move downward to press the auxiliary plate 11, and pushes the auxiliary plate 11 to rotate to the top of the driven pressing plate 29. When the main pressing plate 10 continues to press down and contacts the auxiliary plate 11, the auxiliary plate 11 will transmit the pressing force to the driven pressing plate 29, so that the driven pressing plate 29 moves downward. During the downward movement of the driven pressing plate 29, the connecting rod three 30 of the side wall will rotate, thereby driving the connecting plate 36 and the rotating ring 31 to rotate. The rotation of the rotating ring 31 drives the variable blade 41 to rotate inward and press the steel bar, so that the steel bar is subjected to cutting force in multiple directions during cutting, thereby improving the quality of the cross section of the cut steel bar. After cutting is completed, the steel bar will naturally fall off. When the force acting on the connecting rod one 22 disappears, the spring two 15 drives the auxiliary plate 11 to move upward and return to the original position, and the moving rod 19 is also driven by the auxiliary plate 11 to return to the original position. The connecting rod one 22 returns to the vertical state and waits for the next cutting operation.
