Description

TECHNICAL FIELD

[0001] The utility model relates to a flanging machine technical field, specifically is a round pipe flanging machine with clamping function. BACKGROUND

[0002] The round pipe flanging machine is through the flanging die and is folded to the edge of the round pipe inwards to a certain angle, thereby making the pipeline more firm and beautiful. Specifically, the round pipe flanging machine is extruded or rolled to the edge of the round pipe through the flanging die, so that the plastic deformation occurs, thereby realizing the flanging effect.

[0003] The prior art publication CN113102585B discloses a flanging machine for round pipe air duct, which comprises a left die frame and a right die frame, a left pressure type assembly, a right pressure type assembly, a pressure type clamping driving assembly, a pressure type moving driving assembly and a guide support assembly. The left pressure type assembly comprises a plurality of left pressure wheels installed on the bottom of the left die frame. The right pressure type assembly comprises a plurality of right pressure wheels installed on the bottom of the right die frame in front and back intervals. The outer peripheral wall of the left pressure wheel is provided with a left pressure type conical surface with a gradually decreasing outer diameter from top to bottom. The inclination of the left pressure type conical surface on the plurality of left pressure wheels gradually decreases from front to back. The outer periphery of the right pressure wheel is provided with a right pressure type conical surface with a gradually increasing outer diameter from top to bottom. The guide support assembly comprises two guide support members arranged between the front end and the rear end of the left die frame and the right die frame. The pressure type clamping driving assembly allows the left die frame and the right die frame to approach or move away from each other. The pressure type moving driving assembly allows the pressure wheel to rotate. The present application can be applied to the flanging of air ducts.

[0004] In view of the above-mentioned related technology, the following defects are considered: in the round pipe flanging process, the round pipe will slide due to being pushed, causing the flanging position to change. Therefore, a device is needed that can clamp and keep the round pipe fixed during the flanging process. Because the lengths of round pipes are different, it is not possible to block and clamp from the end of the round pipe, so a round pipe flanging machine with clamping function is needed to solve the above problems.
