Description

Technical Field

[0001] The utility model relates to the technical field of fire door processing, in particular to a shearing machine for processing steel fire doors. Background Art

[0002] Shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear the plate. It uses the moving upper blade and the fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. Shearing machine is a kind of forging machine, and its main function is metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electricity, electrical appliances, decoration and other industries to provide the required special machinery and complete equipment.

[0003] During the production and processing of steel fire doors, a shearing machine is required to cut the fire doors into qualified sizes. The existing shearing machines for processing steel fire doors only clamp and fix the top of the fire doors when shearing them. However, when shearing the fire doors, a large force will be generated, which will cause the fire doors to shake, and it is very easy to cause deviations in the sheared size of the fire doors, which is inconvenient for staff to use. For this reason, we have proposed a shearing machine for processing steel fire doors. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a shearing machine for processing steel fire doors, which is used to solve the above problems.

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

[0006] A shearing machine for processing steel fire doors comprises a workbench, a mounting groove is provided on the top of the workbench, a plurality of equally spaced rotating rollers are rotatably connected inside the mounting groove, a first fixing frame is fixedly connected to the top of the workbench, a shearing assembly is arranged inside the first fixing frame, two symmetrically distributed second fixing frames are fixedly connected to the top of the workbench, motors are arranged on the tops of the two second fixing frames, rotating shafts are fixedly connected to the output ends of the two motors, threaded sleeves are fixedly connected to the bottoms of the two rotating shafts, two threaded sleeves extend to the inside of the second fixing frames, a top clamping assembly is arranged inside the second fixing frame, and two side clamping assemblies are arranged inside the second fixing frame.

[0007] Preferably, the shearing assembly comprises a cylinder fixedly mounted on the top of the first fixing frame, the cylinder extends to the bottom of the first fixing frame, and the output end of the cylinder is fixedly connected to a shearing knife.

[0008] Preferably, the top of the second fixing frame is fixedly connected to a supporting frame, and the motor is fixedly installed on the top of the supporting frame.

[0009] Preferably, the top clamping assembly comprises a threaded rod threadedly connected to the inside of the threaded sleeve, and a pressure plate is rotatably connected to the bottom of the threaded rod.

[0010] Preferably, slide grooves are provided on both sides of the inner wall of the second fixing frame, and sliding blocks are fixedly connected to both sides of the pressing plate, and the two sliding blocks are slidably connected inside the corresponding slide grooves.

[0011] Preferably, two symmetrically distributed slide rails are fixedly connected to the top of the inner wall of the second fixed frame, the bottoms of the two slide rails are slidably connected to slide tables, and the bottoms of the two slide tables are fixedly connected to racks.

[0012] Preferably, the clamping components on both sides include a gear fixedly sleeved on the outside of the threaded sleeve, the gear is meshingly connected with the two racks, and clamping blocks are fixedly connected to both sides of the two racks.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: when it is necessary to shear the fire door, by starting the motor, the rotating shaft rotates, the threaded sleeve rotates, the threaded rod rotates and moves at the same time, the pressure plate moves, and the pressure plate moves to the top of the fire door and fits together, so that the top of the fire door can be fixed, and the threaded sleeve drives the gear to rotate while rotating. Since the gear is meshed and connected with the two racks, through the rotation of the gear, the two racks move oppositely, the clamping block moves, and the clamping block moves to both sides of the fire door, so that the two sides of the fire door can be clamped and fixed, and by starting the cylinder, the shearing knife starts to move, and the shearing knife will shear the fire door. Through the above structure, the fire door can be clamped and fixed before shearing, and the top and both sides of the fire door can be clamped and fixed at the same time, avoiding the traditional method of only clamping and fixing the top of the fire door, resulting in the shearing force causing the fire door to shake during shearing, causing the shearing size of the fire door to deviate, which greatly facilitates the use of the staff.

[0022] Specifically, the output ends of the two motors 8 are fixedly connected with a rotating shaft 10, and the bottoms of the two rotating shafts 10 are fixedly connected with threaded sleeves 11. The two threaded sleeves 11 extend to the interior of the second fixed frame 7. A top clamping assembly is arranged inside the second fixed frame 7. The top clamping assembly includes a threaded rod 12 threadedly connected to the interior of the threaded sleeve 11, and the bottom of the threaded rod 12 is rotatably connected with a pressure plate 13. The top of the fire door can be clamped and fixed by the set top clamping assembly. Slide grooves 14 are provided on both sides of the inner wall of the second fixed frame 7, and sliders 15 are fixedly connected on both sides of the pressure plate 13. The two sliders 15 are slidably connected to the interior of the corresponding slide grooves 14, and the pressure plate 13 is slidably connected to the interior of the slide groove 14 through the sliders 15, so that the pressure plate 13 will not rotate when moving.

[0023] Specifically, the second fixed frame 7 is provided with clamping assemblies on both sides, and the top of the inner wall of the second fixed frame 7 is fixedly connected to two symmetrically distributed slide rails 17, and the bottoms of the two slide rails 17 are slidably connected to slide platforms 18, and the bottoms of the two slide platforms 18 are fixedly connected to racks 19.
