At present, the above-mentioned device has the following shortcomings from the operation mode and cutting process: first, mechanical transmission is adopted, the cam is running all the time, the corresponding parts have a short service life, wear out quickly and have high cost. Moreover, it is a continuous work, if an abnormality occurs in the process, manual stopping is needed, which has uncontrollable safety hazards and loud noise, and the shearing force is fixed and cannot be adjusted; second, the cutting knife is of shearing type, the cutting edge is relatively thin, only suitable for cutting soft steel wire, the cutting edge is easy to break when cutting hard steel wire, and the cross section of the cut steel wire is extremely uneven whether it is soft or hard. Moreover, the steel wire has no fixture at one end, the head end of the steel wire may be bent for a short distance, and there are burrs, in addition, the cutting device occupies a large space area, which cannot be ignored. In view of the above, the hydraulic cutting mechanism is proposed. SUMMARY

[0003] The utility model discloses a hydraulic cutting mechanism, which can solve the above technical problems.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A hydraulic cutting mechanism includes a hydraulic cylinder and a cutter holder, wherein the cutter holder has a containing space, the hydraulic cylinder is installed in the cutter holder, and a hydraulic cylinder rod of the hydraulic cylinder is arranged in the containing space;

[0006] The hydraulic cutting mechanism further includes a first cutting knife and a second cutting knife, both of which have internal channels, wherein the first cutting knife is connected with the hydraulic cylinder rod arranged in the containing space, and the second cutting knife is embedded in the cutter holder and forms a 90° angle with the first cutting knife;

[0007] The first cutting knife is movable, and during the movement of the first cutting knife, the internal channel of the first cutting knife coincides with or is staggered after coinciding with the internal channel of the second cutting knife. The steel wire enters the two coinciding channels, and the first cutting knife moves relative to the second cutting knife to divide the steel wire into two parts.

[0008] Preferably, a through groove that matches the shape of the first cutting knife is arranged below the containing space, and the through groove restricts the linear movement of the first cutting knife.

[0009] Preferably, the bottom of the blade holder also has an extension for mounting a second cutter, which forms an angle with the blade holder, and the first cutter moves toward the angle.

[0010] Preferably, the channels inside the first cutter and the second cutter overlap within the range of the included angle.

[0011] Preferably, it also includes a connecting block located within the accommodating space, the connecting block locking the hydraulic cylinder rod and the first cutter together.

[0012] The beneficial effects of this utility model are:

[0013] 1. The cutting mechanism proposed in this utility model uses hydraulic transmission, which has low noise, low wear, and the cutting force can be adjusted according to the hydraulic pressure, making it safe and reliable.

[0014] 2. This utility model distributes two cutting tools in a staggered manner. By driving one cutting tool to move relative to the other cutting tool, the channels in the two cutting tools can overlap or be staggered, thereby completing the feeding and cutting process. When using this cutting method to cut steel wire, the steel wire cut is flat and burr-free, and there will be no bending. In addition, the small space occupied by the whole device is also an advantage that cannot be ignored. Attached Figure Description
