[0012] Compared with the prior art, the utility model of a cylinder reinforcement rib expansion and pressing machine has the following beneficial effects:

[0013] 1. The first connecting piece is passed through the upper mold body, the mold flap and the lower mold body in sequence, and the first connecting piece is embedded in the support frame, so that the upper mold body and the lower mold body are fixed on the support frame through the first connecting piece, so as to improve the stability of the upper mold body and the lower mold body; at the same time, the upper mold body and the lower mold body are fitted with the inner wall of the cylinder body, so that the upper mold body and the lower mold body can position the cylinder body, thereby preventing the cylinder body from moving in the horizontal direction. The hydraulic cylinder is connected to the booster cone section, and the inclined surfaces of the multiple mold flaps are fitted with the outer wall of the booster cone section, so that when the hydraulic cylinder drives the booster cone section to move downward, the booster cone section presses the multiple mold flaps to move outward, so that the multiple mold flaps press the side wall of the cylinder body to bulge outward, and then the reinforcing ribs are processed on the cylinder body. By setting the first guide groove in the mold flap, winding the first guide sleeve around the outside of the first connecting member, and embedding the first guide sleeve in the first guide groove, the first connecting member can guide the mold flap through the first guide sleeve to avoid the mold flap from shifting when moving, thereby improving the stability of the mold flap movement, and further improving the quality of the barrel body processing. By making the force cone section press the multiple mold flaps to move outward, so that the multiple mold flaps press the side wall of the barrel body to bulge outward, so as to realize the processing of reinforcing ribs on the barrel body. Compared with processing the reinforcing ribs on the side wall of the barrel body by welding, not only is the processing difficulty low, but the overall strength of the barrel body is also improved, thereby improving the product use experience.

[0014] 2. The second connecting piece is passed through the upper mold body and the mold flap in sequence, and the second connecting piece is embedded in the lower mold body, so that the upper mold body and the lower mold body are connected together through the second connecting piece, thereby improving the stability of the upper mold body and the lower mold body, and then improving the accuracy of the upper mold body and the lower mold body in positioning the cylinder body. The second guide groove is set in the mold flap, the second guide sleeve is wound around the outside of the second connecting piece, and the second guide sleeve is embedded in the second guide groove, so that the second connecting piece can move in the second guide groove through the second guide sleeve, so that the second guide sleeve can guide the mold flap, and further improve the stability of the movement of the mold flap.

[0015] 3. When the force cone section presses the mold flap to move outward, the mold flap drives the third connecting piece to move in the make way groove, and the spring is in a stretched state at this time; when the force cone section moves upward and separates the force cone section from the mold flap, the spring resets and drives the third connecting piece and the mold flap to move inward, thereby ensuring that the mold flap and the force cone section remain in contact with each other to prevent the subsequent force cone section from continuing to press the mold flap to move outward, and at the same time, the mold flap can be moved out of the processed reinforcing ribs to facilitate the removal of the cylinder body from the outside of the support frame.

[0016] 4. By arranging the second relief hole in the lower die body and surrounding the second relief hole outside the force - increasing cone section, it is realized that the force - increasing cone section can move within the second relief hole, thereby avoiding interference between the force - increasing cone section and the lower die body and improving the product quality. By arranging the third relief hole in the support frame and surrounding the third relief hole outside the force - increasing cone section, it is realized that the force - increasing cone section can move within the third relief hole, thereby avoiding interference between the force - increasing cone section and the support frame and improving the product quality.

[0017] 5. When the output shaft of the hydraulic cylinder drives the force - increasing cone section to move downward, the output shaft of the hydraulic cylinder moves downward synchronously with the transmission cylinder sleeve. When the transmission cylinder sleeve moves downward a predetermined distance, it contacts the limit switch and triggers the limit switch to work. At this time, the limit switch gives a signal to the hydraulic cylinder, so that the hydraulic cylinder stops working, thereby restricting the downward movement distance of the output shaft of the hydraulic cylinder and improving the product's use experience.

[0018] 6. By connecting the limit plate to the side wall of the support frame by welding and fixing the limit seat on the limit plate, the limit plate supports the limit seat. By embedding the limit wheel into the receiving groove of the limit seat, the limit wheel is rotatably connected to the limit seat, and the cylinder body is placed on the limit wheel, so that the limit wheel can rotate within the limit seat, thereby realizing that the limit wheel can support the cylinder body and improving the stability of the cylinder body.

[0019] 7. By arranging the first guiding part with an inclined surface at one end of the lower die body close to the limit component, when the cylinder body is wound around the outside of the lower die body, it is convenient to drive the cylinder body to move upward, thereby reducing the difficulty of removing the cylinder body from the support frame and improving the product's use experience. By arranging the second guiding part with an inclined surface at one end of the upper die body away from the die segment, it is convenient to wind the cylinder body from top to bottom around the outside of the upper die body, thereby improving the product's use experience.
