Description

Technical Field

[0001] The utility model relates to the technical field of multi-wire cutting machines, in particular to a wire breakage detection device for a multi-wire cutting machine. Background Art

[0002] Multi-wire cutting machines are mostly used in the production and processing of brittle and hard materials such as sapphire, semiconductors, and ceramics. With the rapid development of multi-wire cutting technology, the requirements for cutting technology are getting higher and higher. If the multi-wire cutting machine suddenly breaks during the cutting process, it will cause a lot of damage to the sliced ​​material or produce obvious line marks.

[0003] If the metal wire breaks during use in the existing multi-wire cutting machine, the wire breakage will be detected through the guide wheel baffle. However, due to the large distance between the guide wheel baffle and the wire mesh, the metal wires in high-speed operation are easily tangled together and cannot be thrown onto the baffle, resulting in the failure to trigger the wire breakage alarm, thereby causing the metal wire to be evacuated and the workpiece to be scrapped and the polyurethane layer of the guide wheel to be damaged, which in turn causes great economic losses. Therefore, we propose a wire breakage detection device for a multi-wire cutting machine. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. If the metal wire breaks during use of the existing multi-wire cutting machine, the wire breakage will be detected by the guide wheel baffle. However, due to the large distance between the guide wheel baffle and the wire mesh, the metal wires in high-speed operation are easily entangled and cannot be thrown onto the baffle, resulting in the failure to trigger the wire breakage alarm, thereby causing the metal wire to be evacuated and the workpiece to be scrapped and the polyurethane layer of the guide wheel to be damaged, thereby causing great economic losses.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a preferred solution of the utility model, an extension plate is provided on the left side of the mounting frame, a driving motor is installed on the top end of the extension plate, and a driving wheel is welded to the output end of the driving motor.

[0008] The technical effect of adopting the above further solution is: by turning on the driving motor, the driving wheel can be driven to rotate, thereby driving the metal wire to cut the object to be cut.

[0009] As a preferred solution of the utility model, a rotating column is arranged on the front of the mounting seat, a driven wheel is arranged on the front of the rotating column, a rotating groove is opened on the outer wall of the driven wheel corresponding to the rotating column, the rotating column extends to the inside of the rotating groove, and the rotating column is rotatably connected to the rotating groove.

[0010] The technical effect of adopting the above further solution is: the driven wheel can be relatively movable with the mounting seat through the rotation connection between the rotating column and the rotating groove, so that the mounting seat will not affect the rotation of the driven wheel.

[0011] As a preferred solution of the utility model, sleeve grooves are provided on the outer side walls of the driving wheel and the driven wheel.

[0012] The technical effect of adopting the above further solution is that the metal wire used for cutting can be sleeved inside the sleeve groove through the sleeve groove, so that the objects to be cut can be cut better.

[0013] As a preferred solution of the present invention, the pressing block is made of rubber material, and the pressing block is bonded to the mounting seat.

[0014] The technical effect of adopting the above further solution is that the pressing block made of rubber material can protect the alarm button from damage when a force is applied to the alarm button, thereby increasing the service life of the alarm button.

[0015] As a preferred solution of the utility model, an alarm light is arranged on the right side of the mounting plate.

[0016] The technical effect of adopting the above further solution is: the alarm light can better warn the staff, so that the staff can be notified in time when the metal wire is broken, thereby preventing economic losses caused by a long break time.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] In the utility model, through the design of the slide groove, slider, spring, pressing block and alarm button, when the metal wire of the multi-wire cutting machine is broken, the connection between the driving wheel and the driven wheel will be separated due to the breakage of the metal wire, so that the spring can exert a force on the mounting seat, and the mounting seat can slide quickly toward the alarm button through the slider inside the slide groove under the push of the spring, so that the pressing block can press the alarm button to realize the alarm function, and the alarm can be directly issued when the metal wire is broken, thereby improving the alarm speed and practicality of the multi-wire cutting machine when the metal wire is broken.
