Problems solved by technology

[0004] However, after the profile is rolled into a circle, there will inevitably be a certain length of staggered part, which needs to be cut to ensure a neat cut. Manual cutting will easily lead to deformation of the support ring, low efficiency and high cost.

Embodiment Construction

[0012] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the cutting machine of the present invention includes a body 1, a cutting device and a positioning device. The body 1 is a cabinet or table structure, and its upper surface is made of iron plate or steel plate to provide a strong and stable operation surface. Six positioning rollers 2 are arranged on the operating surface. Preferably, the positioning rollers are rotatably fixedly connected to the connecting plate 3, and the connecting plate 3 is provided with a long hole along its axial direction. For slot 4, use bolts to fix the connecting plate on the operating surface of the body. When adjustment is required, loosen the bolts to adjust.

[0014] The outer edge of the positioning roller 2 forms a circle, and the inner diameter of the circle is the same as the predetermined inner diameter of the support ring. When ...

Abstract

The invention discloses a cutting-off machine used for preparing a timpani backing ring, which comprises a machine body, a cutting-off device and a positioning device, wherein the positioning device is at least four positioning rolls fixedly arranged on the upper surface of the machine body; the cutting device comprises a cutting-off motor, a saw bit and a pushing oil cylinder, wherein the cutting-off motor can be arranged on the rail in a back-and-forth sliding mode; the saw bit is fixedly arranged on the end part of the output shaft of the cutting-off motor; and the pushing oil cylinder can push the cutting-off motor to move along the rail. The cutting-off machine disclosed by the invention has the advantages of simple structure, high working stability, simple operation step and high efficiency; the backing ring can be positioned by the positioning rolls to prevent from deforming and displacing in the cutting-off process, can be operated by single person, is suitable for cutting off the backing rings of different diameters and is convenient to regulate; manpower is saved, and cost is lowered; and meanwhile, the cutting edge is tidy to effectively improve product quality.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a cutting machine capable of cutting the interlaced parts of drum support rings. Background technique [0002] The timpani is a relatively common musical instrument and the earliest percussion instrument used in orchestras. Existing timpani usually consists of a drum skin, a drum pot, supporting legs and pedals. The drum skin is buckled on the upper surface of the drum pot. The board can adjust the tension of the drum skin, and then call out the pitch specified in the music, and the pointer on the pitch display panel installed on the outer wall of the drum pot can display the pitch. [0003] The drum pots of the existing timpani are mostly made by casting, the surface smoothness is poor and the follow-up processing is complex and loaded down with trivial details, and the pot is heavy and the product quality is not high. In order to change this situation, the aluminum profile is now used as ...
