Description

Technical Field

[0001] This utility model relates to the technical field of cylindrical production equipment, specifically to a one-time cylindrical forming machine. Background Technology

[0002] A cylindrical forming machine is an important piece of machinery, mainly used to roll flat or cylindrical materials into cylindrical shapes. The existing cylindrical forming process generally involves first bending the steel plate on a bending machine and then forming the cylinder through the cylindrical forming machine. This requires multiple machines and multiple processes to complete the cylinder forming, making the operation cumbersome. It is not possible to complete the one-time forming of the cylinder directly on one machine, resulting in low forming efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a one-time cylindrical forming machine that can quickly complete the forming of a cylindrical shape and improve the forming efficiency of the cylindrical shape.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A one-time cylindrical molding machine includes a frame, with a cylindrical inner mold disposed at the center of the frame. An upper mold and a lower mold disposed on both sides of the cylindrical inner mold are respectively installed on the frame, and the upper mold and the lower mold are respectively connected to a hydraulic cylinder. The center of the opposite side of the upper mold and the lower mold is respectively provided with a semi-circular arc-shaped die opening that matches the cylindrical inner mold.

[0006] The above-mentioned cylindrical one-time forming machine has trapezoidal protrusions on both sides of the upper mold opening, and the inclined sides of the protrusions are arranged inward to form an flared opening; trapezoidal grooves are opened on both sides of the lower mold opening to insert into the trapezoidal protrusions.

[0007] In the aforementioned cylindrical one-time forming machine, the hydraulic cylinder is mounted on the machine frame via a hydraulic cylinder mounting base.

[0008] The aforementioned cylindrical one-time forming machine also includes a control system, wherein the controlled end of the hydraulic cylinder is connected to the output end of the control system.

[0009] In the aforementioned cylindrical one-time forming machine, induction plates are respectively installed on one side of the upper mold and the lower mold, and a proximity switch is installed on the frame to determine the upper mold or the lower mold is in place by reacting with the induction plates. The output end of the proximity switch is connected to the input end of the control system.

[0010] The aforementioned cylindrical one-time forming machine has slide rails symmetrically arranged on the frame, and sliders that slide and are symmetrically fitted to the slide rails are arranged on both sides of the bottom end of the upper and lower molds. A sensing plate is installed on the sliders, and a proximity switch is installed on the slide rails.

[0011] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0012] This utility model provides a one-time cylindrical forming machine. Through the cooperation of the upper mold, the lower mold, and the inner cylindrical mold located between the upper mold and the lower mold, the one-time forming of the cylinder can be completed quickly, reducing the conversion between multiple equipment and multiple processes. Furthermore, the flared opening formed by the protrusion of the upper mold can introduce the end of the steel plate into the semi-circular arc-shaped mold opening of the upper mold. Through the cooperation of the protrusion of the upper mold and the groove of the lower mold, the steel plate is clamped between the circular mold opening formed by the upper and lower molds and the inner cylindrical mold, which facilitates forming and improves the forming efficiency of the cylinder. The stability of forming is ensured by the cooperation of the control system and the proximity switch. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A cylindrical one-time forming machine, such as Figures 1 to 2 As shown, the machine includes a frame 1, with a cylindrical inner mold 4 at the center of the frame 1. An upper mold 2 and a lower mold 3 are respectively installed on the frame 1 on both sides of the cylindrical inner mold 4. The upper mold 2 and the lower mold 3 are respectively connected to a hydraulic cylinder 5. The hydraulic cylinder 5 is installed on the frame 1 through a hydraulic cylinder mounting seat 6.

[0018] The upper mold 2 and the lower mold 3 are respectively provided with semi-circular arc-shaped mold openings on opposite sides to fit the inner cylindrical mold 4. The upper mold 2 has trapezoidal protrusions 10 on both sides of the mold opening, and the inclined sides of the protrusions are arranged inward to form an flared opening. The lower mold 3 has trapezoidal grooves 11 on both sides of the mold opening to insert into the trapezoidal protrusions 10.

[0019] It also includes a control system, with the controlled end of cylinder 5 connected to the output end of the control system.

[0020] Induction plates 9 are installed on one side of the upper mold 2 and the lower mold 3 respectively. A proximity switch 8 is installed on the frame 1 to determine whether the upper mold 2 or the lower mold 3 is stamped in place by reacting with the induction plates 9. The output end of the proximity switch 8 is connected to the input end of the control system.

[0021] The frame 1 is symmetrically equipped with slide rails 7, and the bottom ends of the upper mold 2 and the lower mold 3 are symmetrically equipped with sliders that slide and fit with the slide rails 7. The sensing plate 9 is installed on the sliders, and the proximity switch 8 is installed on the slide rails 7.

[0022] In use, the steel plate to be formed is placed between the lower mold 3 and the inner cylindrical mold 4. The lower mold 3 is controlled to move towards the center of the inner cylindrical mold 4 to perform preliminary stamping on the steel plate, completing half of the cylindrical forming. When the proximity switch 8 senses that the sensing plate 9 on the lower mold 3 is in place, the lower mold 3 is controlled to stop moving. At the same time, the upper mold 2 is controlled to move towards the center of the inner cylindrical mold 4 to perform secondary stamping on the steel plate. When the proximity switch 8 senses that the sensing plate 9 on the upper mold 2 is in place, the upper mold 2 is controlled to stop moving, completing the cylindrical forming.

[0023] Since the upper mold 2 has an flared opening composed of protrusions 10 at its end, when the upper mold 2 moves, the two unformed ends of the steel plate will move along the flared opening to the semi-circular arc mold opening at the center of the upper mold 2, and the steel plate will be rounded by the stamping of the upper mold 2. At the same time, after the protrusions 10 of the upper mold are inserted and connected to the grooves 11 on the lower mold 3, a complete circular mold opening is formed between the two semi-circular arc mold openings, and it cooperates with the outer wall of the inner mold of the cylinder to ensure the stability of the cylinder forming.

[0024] This utility model provides a one-time cylindrical forming machine. Through the cooperation of the upper mold, the lower mold, and the inner cylindrical mold located between the upper mold and the lower mold, the one-time forming of the cylinder can be completed quickly, reducing the conversion between multiple equipment and multiple processes. Furthermore, the flared opening formed by the protrusion of the upper mold can introduce the end of the steel plate into the semi-circular arc-shaped mold opening of the upper mold. Through the cooperation of the protrusion of the upper mold and the groove of the lower mold, the steel plate is clamped between the circular mold opening formed by the upper and lower molds and the inner cylindrical mold, which facilitates forming and improves the forming efficiency of the cylinder. The stability of forming is ensured by the cooperation of the control system and the proximity switch.
