It can only be cut by manual control, which will result in different lengths of the cut fuse wire. Secondary trimming is required to keep the lengths of the fuse wires consistent. Making the fuse wire length maintain the desired length through manual cutting will cause waste of time and human resources.

[0025] The following combines the drawings to elaborate on the preferred embodiments of the present utility model, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 3 , the embodiments of the present utility model include:

[0027] A wire cutting machine based on patch fuses, which includes a workbench 1 and a feeding component 2, a limiting component 3, a cutting component 4 and a fuse storage box 5 installed on the workbench 1. The feeding component 2 is used for guiding and placing fuses. The limiting component 3 is used for limiting the length of the cut fuses and is opposite to the feeding component 2. The cutting component 4 is located between the feeding component 2 and the limiting component 3 and is used for cutting fuses. The fuse storage box 5 is located below the cutting knife of the cutting component 4 and is used for storing the cut fuses.

[0028] The feeding component 2 includes a guide block 21, a lower cutting knife 22 and a pressing plate 23. A fuse groove 210 is provided on the guide block 21. A horn opening 211 for guiding and placing fuses is provided at the entrance end of the fuse groove 210. A lower cutting knife 22 is installed on the guide block 21 at the end of the fuse groove 210. A pressing plate 23 is installed at one end of the guide block 21 close to the lower cutting knife 22. The setting of the pressing plate 23 prevents the fuse from jumping out during the cutting process.

[0029] The limiting component 3 includes a micrometer base 31 and a micrometer 32 horizontally installed on the micrometer base 31. The height of the micrometer 32 is the same as that of the fuse on the feeding component 2.

[0030] The cutting component 4 includes a cutting bracket 41, a pneumatic valve pressure module 42, an upper tool rest 43, an upper cutting knife 44, a photoelectric detection module 45, an electro-pneumatic magnetic valve 46, and a linear slide rail 47. The pneumatic valve pressure module 42 and the electro-pneumatic magnetic valve 46 are installed on the cutting bracket 41. The pneumatic valve pressure module 42 is connected to the electro-pneumatic magnetic valve 46 through an air pipe. The electro-pneumatic magnetic valve 46 is externally connected to a negative pressure device. The pneumatic valve pressure module 42 uses a cylinder. The pneumatic valve pressure module 42 drives the upper tool rest 43 to move up and down. The upper tool rest 43 is slidably connected to the cutting bracket 41 through the linear slide rail 47. The upper cutting knife 44 is installed on the upper tool rest 43. An installation chute 430 for installing the upper cutting knife 44 is provided on the upper tool rest 43. A waist-shaped hole 440 for adjusting the installation height is provided on the upper cutting knife 44. The cutting edges of the upper cutting knife 44 and the lower cutting knife 22 face each other. The pneumatic valve pressure module 42 is equipped with a photoelectric detection module 45 for detecting and identifying a fuse with a quantitative length. The photoelectric detection module 45 is electrically connected to the electro-pneumatic magnetic valve 46.

[0031] When the wire cutting machine based on the patch fuse of the present utility model is working, the wire cutting machine is powered on. The fuse to be cut is transmitted along the fuse groove 210 of the guide block 21 towards the cutting opening. The fuse slowly approaches the micrometer 32 until it contacts it. When the photoelectric detection module 45 detects the fuse with the required length, for example, when the required length of the fuse is 15 mm, the photoelectric detection module 45 generates a high-level trigger bit from 0 to 1. The pneumatic valve pressure module 42 generates pressure to make the upper cutting knife 44 move down to perform a cutting action. At the same time, the photoelectric detection module 45 changes from a high level to a low level and waits for triggering. At this time, a fuse with a length of 15 mm will fall into the fuse storage box 5 below the cutting opening. When the fuse storage box 5 is taken out, it is found that the length of the fuse is uniform and there is no bending phenomenon. When placed in a porcelain tube, it can just be flush with the tube opening, and can be directly welded in the next step, saving time and labor costs.

[0032] The wire cutting machine based on the patch fuse of the present utility model can continuously cut fuses with consistent required lengths. The lengths of the fuses are uniform and there is no bending phenomenon, which can improve production efficiency.

All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present utility model.
