Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1-5, a steel scrap gantry shearing machine includes a frame 1, a shearing mechanism 3, a hydraulic rod 4 and an anvil 2 are installed on the frame 1, wherein the anvil 2 is located below the shearing mechanism 3 and is used for placing steel scrap, the shearing mechanism 3 is used for shearing the steel scrap on the anvil 2, and during the shearing process, the shearing mechanism 3 adapts to the dimension of the steel scrap in the vertical direction and presses the steel scrap from two sides of a shearing knife 302, the hydraulic rod 4 is used for driving the shearing mechanism 3 to displace in the vertical direction, so as to realize feeding and retracting, and the shearing and pressing of the steel scrap by the shearing mechanism 3 are driven by the same hydraulic rod 4.

In this scheme, order about through same hydraulic stem 4 and cut mechanism 3 and realize cutting and pressing holding the same power supply of shearing sharing to scrap steel, press holding with shearing, the action interval error between the two is less, and shearing efficiency improves to some extent.

In this scheme, shear mechanism 3 can the ascending size of vertical side of self-adaptation steel scrap edge, so need not adjust the hydraulic drive of hydraulic stem 4, and the steel scrap when being pressed and holding, also can not receive too big hydraulic pressure force and the too flat of being pressed.

In this scheme, press from the both sides of shearing sword 302 and hold and cut the completion back, press and hold just cancel, so in the shearing process, the condition that the perk splashes can not take place for the scrap steel, and the shearing process is safer.

As shown in fig. 3-5, the shearing mechanism 3 includes a main plate 301 slidably mounted on the frame 1 along the vertical direction, the main plate 301 is horizontally disposed, the upper end surface of the main plate 301 is connected to the hydraulic rod 4, the hydraulic rod 4 is activated and can drive the main plate 301 to displace along the vertical direction, and the lower end surface of the main plate is provided with a shearing knife 302.

The whole scrap steel shearing process is specifically represented as follows:

first, scrap steel is placed on the anvil 2;

then, the hydraulic rod 4 is started to drive the main plate 301 to move downwards vertically, and in the process of moving downwards:

the pressing plate 309 contacts with the scrap steel firstly, then, the pressing plate 309 stops moving downwards or the hollow scrap steel is compressed by hydraulic pressure to enable the pressing plate 309 to slightly move downwards due to the obstruction of the scrap steel, the spring 304 is compressed, the spring 304 is used as intermediate transmission to enable the pressing plate 309 to press and hold the scrap steel, and the shearing knife 302 can continuously move downwards due to the fact that the shearing knife is not in contact with the scrap steel;

when the shear knife 302 moves down to contact with the scrap, the scrap shearing process begins, during which the spring 304 is continuously compressed;

after shearing, hydraulic stem 4 orders about mainboard 301 and vertically shifts up, moves up the in-process, shears 302 earlier breaks away from the contact with the scrap steel, and wait until spring 304 release elasticity contact after, clamp plate 309 just breaks away from the contact with the scrap steel, so whole scrap steel shearing in-process, the both sides of scrap steel are all firmly pressed and are held, can not take place to stick up the problem of splashing.
