The invention discloses a timpani pot bottom processing device, which comprises a base frame, an upper beam, a stretching cylinder, an upper concave die, a side pressing ring mechanism and a lower convex die. The upper beam is supported by upright columns to be disposed on the base frame, the stretching cylinder is fixedly disposed on the upper portion of the upper beam, the upper concave die can be driven by the stretching cylinder to move up and down, the side pressing ring mechanism can be pushed by a side pressing cylinder disposed below the base frame to move up and down, the lower convex die is fixedly disposed on the base frame, and an end of the lower convex die is semispherical. By the aid of a semispherical bump and recess symmetrical structure and good extensibility of red copper, a red copper plate can be conveniently stretched to form a pot body, efficiency is greatly improved, stability of pot bottom quality and identity of products can be guaranteed effectively by the aid of stable forming in a stretching process, production quality of timpani is improved, and competitiveness of enterprises is enhanced.
Description
technical field [0001] The invention relates to a timpani, in particular to a timpani pot bottom processing device. Background technique [0002] The timpani is a relatively common musical instrument and the earliest percussion instrument used in orchestras. The existing timpani usually consists of a drum skin, a drum body, supporting legs and pedals. The drum body is usually semi-spherical, the drum skin buckles the upper surface of the drum body, and the drum skin is connected to the pedals through a pull rod device located in the drum cavity. The tension of the drumhead can be adjusted by stepping on the pedal, and then the pitch specified in the music can be called out. The pointer on the pitch display panel installed on the outer wall of the drum body can display the pitch. [0003] Wherein, the drum body includes the bottom of the pot and the side part of the drum welded together with the bottom of the pot. In the past, the hemispherical pot bottom was generally press...
