Description

Technical Field

[0001] The utility model relates to a box-type scrap steel shearing machine, belonging to the technical field of scrap steel shearing. Background Art

[0002] Scrap shears are used to shear scrap steel for recycling. Most scrap shears in the prior art are gantry shears, which are also called scrap shears. Gantry shears have a wide range of applications, and can be used as processing equipment for metal recycling units, as furnace material processing in factory foundries, and as metal shearing processing equipment in the machinery and construction industry.

[0003] Traditional small and medium-sized gantry shears use conveyor belts to feed materials when shearing. When the materials are transported to the shearing position, the hydraulic cylinder drives the blade to move to achieve shearing. The following deficiencies exist in the shearing process: first, when the materials are loose and messy, the material feeding is likely to be unstable during the transportation of the materials. The materials may shake or jump and deviate from the two sides of the feeding mechanism, resulting in a small amount of materials accumulating on both sides of the feeding mechanism and requiring secondary shearing; second, the conveyor belt transportation method is not stable enough. When transporting materials with larger mass, the torque of the conveyor belt is small, the transportation pressure is large, and it is easy to have wear and tear failures and poor stability. Due to its large size and weight and complex structure, it is not conducive to on-site operation and maintenance, and when used, it has low work efficiency and high energy consumption.

DETAILED DESCRIPTION

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 , 2As shown in , 3, 4, and 5, a box-type scrap steel shearing machine in this embodiment includes an open box body, and a hopper 3 is connected to the opening of the box body, and the hopper 3 is connected to the inner cavity of the box body. A pressing chamber and a shearing chamber are provided in the box body, and the shearing chamber is arranged below the pressing chamber. A pressing head 4 is provided in the pressing chamber, and a horizontally arranged pressing cylinder 5 is arranged in the box body. The pressing cylinder 5 extends a rod and is fixedly connected to the pressing head 4. The pressing cylinder 5 drives the pressing head 4 to move forward and backward along the pressing chamber, and compresses the scrap steel that falls into the pressing chamber from the hopper 3 to form a pressing block, which is then arranged in the shearing chamber. An upper blade seat 1 is arranged in the shearing chamber, and an upper blade 9 is arranged on the upper blade seat 1. A shearing head 7 is provided in the shearing chamber, and a horizontally arranged shearing cylinder 6 is arranged in the box body. The shearing cylinder 6 extends a rod and is fixedly connected to the shearing head 7. A lower blade 8 is arranged on the top of the shearing head 7, and the upper blade 9 and the lower blade 8 are arranged relative to each other, and the installation position of the upper blade is higher than the installation position of the lower blade. The box body is provided with a discharge port 11 which is connected to the shearing chamber. The shearing oil cylinder 6 drives the shearing head 7 to move forward and backward along the shearing chamber, driving the lower blade 8 to approach or move away from the upper blade 9. When the lower blade 8 approaches the upper blade 9, the two cooperate to shear the pressing block to form sheared material, which is then pushed to the discharge port 11 by the shearing head 7 for discharge.

[0018] Cutting head

[0019] There is no gap between the pressing head and the shearing head in the vertical direction (the pressing head moves along the upper surface of the shearing head), which avoids damage to the shearing cylinder due to operating errors.

[0020] The open box includes a base 13, a front frame 2 is arranged at the front end of the base 13, a rear frame 10 is arranged at the rear end of the base 13, and side frames 12 are arranged on both sides of the base 13. A discharge port 11 is arranged on the front frame 2.

[0021] The front frame 2 is symmetrically provided with guide grooves, and guide bars 14 are respectively arranged on both sides of the pressing head 4. The guide bars 14 are respectively arranged in the corresponding guide grooves to play a guiding role during the movement of the pressing head.

[0022] The invention has a simple structure, occupies a small area, is easy to operate, improves shearing efficiency, can add materials continuously, and reduces operating costs.

[0023] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
