Accordingly, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In addition, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Referring to fig. 1 to 6, the present application provides a movable tool rest assembly of a gantry shearing machine. The gantry shearing machine is used for cutting off a metal material and is provided with a movable tool rest positioned on the upper side and a fixed tool apron positioned on the lower side; the movable cutter frame can move downwards to be matched with the fixed cutter seat to cut off the materials. Fig. 1 is a schematic structural diagram of a shearing structure of a gantry shearing machine in an embodiment of the present application, and a movable tool rest assembly s is driven by a shearing oil cylinder, so as to realize up-and-down movement to shear a material.

The knife rest assembly of the gantry shearing machine comprises: the cutter comprises a plurality of blades 1, a cutter frame main body 2 and a guide rail 3; wherein, the tool rest main body 2 is provided with at least two boss parts 21 which penetrate up and down at one side for installing the blade 1; the tool rest main body 2 is provided with a bent blade mounting position 22 at the bottom edge position of one side with the boss part 21; an oil cylinder mounting position 23 is arranged at the top position of the boss part 21; the guide rails 3 are provided on both sides of the tool rest main body 2.

Referring specifically to fig. 2 and 3, the main body 2 of the tool holder is provided with two boss portions 21 penetrating up and down, and the boss portions 21 make the insert mounting portion 22 in a concave-convex bent shape. Therefore, the required small-size cut material can be formed in one step, the efficiency is high, and the cost is low. At the moment, if the stress point of the shearing oil cylinder arranged on the movable knife rest is unreasonable, the movable knife rest is subjected to couple action to generate extra side-turning moment, so that the abrasion of the guide rails 3 on the two sides of the movable knife rest is aggravated. Specifically, the cylinder mounting position 23 is used for mounting a shearing cylinder and bearing a pushing force from the shearing cylinder so as to push the movable knife rest assembly to shear the material downwards. In the embodiment of the application, the oil cylinder mounting positions 23 are arranged on the boss parts 21, and the two oil cylinder mounting positions can be arranged in a one-to-one corresponding relationship, namely, one oil cylinder mounting position is arranged on each boss part 21; therefore, the blades 1 are uniformly distributed on the oil cylinder mounting position 23 in the horizontal direction, namely around the stress point of the shearing oil cylinder, the overturning moment of the movable knife rest in the operation process is effectively reduced, so that the stress of the movable knife rest is more reasonable, the abrasion of the guide rails 3 on two sides is reduced, and the service life of the guide rails 3 on two sides is prolonged.

Further, the boss portion 21 includes: first boss portions 211 provided at both sides and engaged with the guide rail 3, and a second boss portion 212 provided between the two first boss portions 211. Here, the boss portion 21 includes two first boss portions 211 at both sides and a second boss portion 212 at the center, and the first boss portions 211 at both sides are engaged with the guide rails 3, so that the pushing force of the shearing cylinder is more uniformly distributed between the two guide rails 3, and the wear is reduced.

Referring to fig. 6, in some embodiments, the bottom height of the first boss portion 211 is lower than the bottom height of the second boss portion 212 on both sides. When the movable knife rest cuts and shears materials downwards, the first boss parts 211 on two sides participate in shearing firstly, and the whole rigidity and the strength of the movable knife rest can be improved.

In some embodiments, the tool holder body 2 is provided with one second boss portion 212. It should be noted that the number of the second boss portions 212 may be determined according to actual conditions, and is not limited herein.

In some embodiments, referring to fig. 6, the width of the guide rail 3 is not less than the width of the tool holder body 2. The width of the guide rail 3 is increased, so that the structural strength of the guide rail can be enhanced, and the service life of the guide rail is prolonged. In addition, the width of the guide rail 3 is increased, so that the stress condition of the whole tool rest main body 2 can be improved to a certain degree.

In some embodiments, the bottom of the guide rail 3 is lower than the bottom of the tool holder body 2; the top of the guide rail 3 is higher than the top of the main body 2 of the tool holder. Specifically, the length of the guide rail 3 is increased, so that the stress area of the guide rail 3 is larger when the guide rail slides, the force applied to a single point is reduced, and the service life of the guide rail 3 is prolonged to a certain extent.

Referring to fig. 2 and 3, in some embodiments, the bottom of the cartridge body 2 is disposed obliquely in the left-right direction such that the blade mount 22 and the blade 1 are disposed at an oblique angle.

In some embodiments, the tool holder body 2 is a one-piece component with the guide rail 3. The provision of integral parts here reduces the number of parts.

Referring to fig. 4, in some embodiments, the insert mounting location 22 is provided with a plurality of threaded holes 221 for mounting the insert 1. Thus, the insert 1 can be mounted in the insert mounting location 22 by means of a threaded connection. In addition, the blade 1 can be mounted in various ways, and can be partially connected by screw threads.

Referring to fig. 5, the tool holder main body 2 is provided with a groove structure 24 on the other side opposite to the boss portion 21. The groove structure 24 reduces the weight of the tool holder body 2 and reduces the energy consumption required by the tool holder body 2 during movement.

The embodiment of the application also provides a gantry shearing machine, which is provided with the moving tool rest assembly of the gantry shearing machine provided by the embodiment part of the application. For the moving blade holder assembly of the gantry shearing machine, reference is made to the description in the previous section, and the description is omitted here.
