Description

Technical Field

[0001] The invention relates to the technical field of elbow shaping dies, in particular to a full elbow shaping die. Background Art

[0002] Elbow full shaping dies are usually mold equipment used to make elbows in industrial production. This type of mold is usually designed to process metal pipes so that they are bent at specific angles and shapes. These molds can be customized as needed to accommodate the production of elbows of different diameters and angles. It usually consists of multiple parts, each with a specific function and shape, so that the final elbow product with accurate size and shape can be manufactured.

[0003] Spherical shaping is one of the key steps in the manufacture of pipe elbows. After the pipe is preheated, an iron ball or ball-shaped tool is inserted into the inner diameter of the pipe. By applying pressure, usually through a hydraulic system, the iron ball is gradually squeezed out of the inner diameter of the pipe. During this process, the metal in the inner diameter of the pipe will gradually stretch and deform to form the desired spherical structure.

[0004] In traditional spherical shaping, operators need to constantly place iron balls into the heated elbow for pressurized shaping. At this time, operators need to approach high-temperature equipment or use force to push the iron balls in. This process poses unexpected risks such as burns and pinching.

[0005] In summary, the prior art lacks a technology for automatically feeding spheres when performing spherical shaping on elbows. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a full elbow shaping die.

[0012] Preferably, transmission racks are connected and fixed on both sides of one end of the iron ball loading seat, the transmission racks are meshed with transmission wheels for transmission, and a groove is provided on the iron ball loading seat.

[0013] Preferably, the pushing mechanism includes a push rod group, one end of the push rod group is rotatably connected to the iron ball loading seat, the end of the push rod group connected to the iron ball loading seat is connected and fixed with a gear, a fixed rack is connected and fixed to the equipment frame, the fixed rack is meshed with the gear for transmission, the other end of the push rod group is rotatably connected to a push ball rack, the push ball rack is arranged in a U-shaped structure, and the push ball rack is slidably matched with the iron ball loading seat.

[0015] Preferably, the output end of the hydraulic cylinder is fixedly connected to a connecting seat, a movable rod is rotatably connected to the connecting seat, and the other end of the movable rod is rotatably connected to a ball pressing block.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When the elbow is spherically shaped, the iron ball loading seat can automatically lift the iron ball to a suitable height, and then the iron ball automatically falls into the elbow under the action of the pushing mechanism, effectively reducing the problems and safety hazards caused by manual operation, and improving the safety, accuracy and production efficiency of the elbow manufacturing process; By setting a baffle on the elbow mold, the iron ball that slides out of the elbow can be blocked to prevent the extruded iron ball from falling and injuring the staff. At the same time, the iron ball can smoothly pass through the ball guide hole and fall into the iron ball feeding seat, completing the automatic recovery of the iron ball and improving production efficiency. By arranging a ball stopper on the elbow mold, the pushing mechanism can limit the position of the iron ball while pushing the iron ball into the elbow, so that the iron ball can fall into the elbow accurately, avoiding accidental falling of the iron ball and causing safety hazards.
