Technical Field
[0001] The present invention relates to the technical field of cutting equipment, and particularly relates to an automatic cutting equipment for a shot blasting machine protective shell. Background Art
[0002] A shot blasting machine is a processing technology that high-speed throws steel sand and steel shot in the shot blasting machine onto the surface of a material object. Compared with other surface treatment technologies, the shot blasting machine has a faster speed and higher efficiency; generally, a protective shell for protecting users is provided outside the shot blasting machine. Generally, it is necessary for operators to manually cut the protective shell of the shot blasting machine to be processed, which is not conducive to the mass production of the protective shell of the shot blasting machine, resulting in low processing efficiency in the production of the protective shell of the shot blasting machine; the existing automatic cutting equipment for the protective shell of the shot blasting machine usually cannot perform full-automatic cutting processing for protective shells of different sizes. Summary of the Invention

[0004] Further, the housing mechanism further includes a bottom electric cylinder fixedly installed at the bottom of the housing, the sliding frame is fixedly installed with the output end of the bottom electric cylinder, a tension spring is arranged between the pushing frame and the housing, a compression spring is arranged between the top post and the housing, a discharge slope is fixedly installed on the housing, and a plurality of friction bottom blocks are arranged inside the housing.
[0005] Further, two roller brackets are slidably installed below the housing, four rollers are rotatably installed on the roller brackets, a connecting rod is fixedly installed on the sliding frame, a slope section is arranged on the connecting rod, a triangular block is fixedly installed inside the roller, the triangular block contacts the connecting rod, and the protective shell is placed on the rollers.
[0006] During use, the protective shell is pushed into the outer shell through the discharge slope. The protective shell is located on the roller. The protective shell pushes the push frame to move through the top column. The tension spring is stretched and the compression spring is compressed. Subsequently, the connecting column drives the chute rod to slide along the fixed column, thereby driving the bottom rotating rod to rotate, and then driving the two saw blade holders to slide inward along the outer shell. Thus, the upper lifting frame is driven to descend and the lower lifting frame ascends through the upper rotating rod and the lower rotating rod. The upper left knife slides along the upper lifting frame, and the lower right slider slides along the lower lifting frame. The upper spring and the lower spring are stretched. At the same time, the descent of the upper lifting frame drives the upper left slider to descend, and the ascent of the lower lifting frame causes the lower right slider to ascend, so that the lower right knife, the lower left knife, the upper right knife, and the upper left knife reach the cutting initial position. The upper right slider contacts the upper lifting frame through the lower inner spring, and the lower left slider contacts the lower lifting frame through the upper inner spring.

The upper chute rod slides in the vertical chute of the side vertical rod, and the lower chute rod slides in the vertical chute of the side vertical rod.
[0009] As the bottom electric cylinder continues to contract, the side vertical rods move towards the outer shell, inserting the lower right knife, the lower left knife, the upper right knife, and the upper left knife into the protective shell. Subsequently, the bottom electric cylinder continues to contract, driving the carriage to continue moving towards the outer shell, driving the motor and the motor gear to move inward, and finally the motor gear is engaged and docked with the docking gear ring.
