Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of tubular castings, and discloses a rounding device for tubular castings. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance. Among them, tubular castings are used to connect cast iron pipes, steel pipes and other pipes to facilitate the assembly, disassembly and maintenance of the pipeline system.

[0003] Since the tube casting is prone to deformation during the casting process, if the tube casting is not rounded, it will affect the subsequent use. The existing rounding correction is usually done manually along the periphery of the tube casting mouth with a wooden hammer. Although this method can solve the deformation problem of some tube castings, the rounding correction cycle is long and it is easy to damage the surface of the tube casting, which leads to low rounding correction efficiency.

[0004] Therefore, a tubular casting rounding device with automatic rounding is needed to solve the problems existing in the prior art. Utility Model Content

The output shaft of the servo motor rotates to drive the bidirectional screw to rotate, so that the push plates move toward the side closer to each other.

[0009] In a preferred embodiment of the utility model, a support frame is also included. The left and right sides of the top of the shell are fixedly connected to the support frame, and the roundness correction rod slides inside the support frame.

The two gears are meshed. Push plates 63 that pass through the top of the shell 1 are threadedly arranged on the left and right ends of the two-way screw rod 64. Two slide grooves are provided on the left and right sides of the shell 1. The push plate 63 slides in the slide groove. A rounding rod 62 is fixedly connected to the push plate 63. The output shaft of the servo motor 66 drives the two-way screw rod 64 to rotate, so that the push plate 63 moves to the side close to each other. It also includes a support frame 61, and the left and right sides of the top of the shell 1 are fixedly connected to the support frame 61. The rounding rod 62 slides inside the support frame 61.
