Description

Technical Field

[0001] The utility model relates to the technical field of cable bridge production, in particular to a cutting device for cable bridge production. Background Art

[0002] In the cable tray production industry, the cable tray is an important supporting structure used to support and protect cables, wires and other communication equipment. With the development of communication technology and the expansion of its application scope, the demand for cable trays is also increasing. Therefore, the production of high-quality cable trays has become one of the important tasks of manufacturers.

[0003] However, traditional cable tray cutting equipment has some shortcomings:

[0004] Reliance on manual operation:

[0005] Traditional cable tray cutting equipment usually requires operators to perform manual adjustments and operations, including adjusting the cutting angle, moving the cutting position, etc. This reliance on manual operation can easily lead to inconsistent operations, affecting cutting quality and efficiency.

[0006] The cutting angle is not flexible:

[0007] Traditional equipment usually lacks the function of adjusting the cutting angle and can only perform fixed-angle cutting. This limitation makes it impossible to flexibly adjust the cutting angle when facing cable trays of different shapes or sizes, affecting the applicability and flexibility of the equipment.

[0008] The cutting process is unstable:

[0009] Since traditional equipment is affected by manual operation during the cutting process, the bridge position may be unstable during the cutting process, resulting in unstable cutting quality, or even cutting deviation or poor quality.

[0010] Security is difficult to guarantee:

[0011] Since traditional equipment may have safety hazards such as unstable bridge position during the cutting process, the safety of operators cannot be effectively guaranteed and there are certain safety hazards.

[0012] Therefore, this invention proposes a cutting device for cable tray production to solve the above problems. Utility Model Content
