Description

Technical Field

[0001] The invention belongs to the technical field of machining, and in particular relates to a steel plate drilling machine. Background Art

[0002] In machining work on steel plates, it is often necessary to drill holes in the steel plates. When drilling holes in steel plates, steel plates within a certain thickness range are generally processed by CNC punching machines. However, the CNC punching machine itself is relatively expensive, and a mold is required for punching. The use of the mold is limited to a certain number of times. If a CNC punching machine is used to drill holes, the cost is relatively high. For thicker steel plates, a drilling machine is generally used for drilling.

[0003] Large drilling machines generate a lot of debris during the drilling work, and it is not convenient to stop the machine for cleaning. The existing large drilling machines do not have a debris cleaning function. When a lot of debris accumulates on the drilling machine, it will be entangled on the drilling machine drill bit, which is easy to cause danger. The workload of debris cleaning is large and it is not convenient to clean, resulting in a lot of debris accumulating and adhering to the drilling machine. The workshop environment and sanitation are poor, which is not conducive to the maintenance of the drilling machine. Summary of the invention

[0025] A debris pushing device 8 is provided on the inclined workbench bottom plate 11; the debris pushing device 8 includes a screw 81, a pushing plate 82, and a pushing motor 83. A screw 81 is installed in parallel on both sides of the workbench bottom plate 11 through a bearing seat, and the pushing plate 82 is threadedly installed on the screw 81. The bottom of the pushing plate 82 is in contact with the workbench bottom plate 11. The pushing motor 83 is installed at the bottom of the workbench bottom plate 11, and the pushing motor 83 is connected to the screw 81 in transmission. When smaller debris or powder is adsorbed on the workbench bottom plate 11 to form a thicker waste layer, the screw 81 is driven to rotate by the pushing motor 83, and the pushing plate 82 is driven to push the waste (debris) into the drop port, and then the waste is transported and discharged through the debris conveyor 6.

The structure is simple and the operation is convenient; it is prevented that the drill bit drills into the adjustable longitudinal beam 3 during the drilling work; the pressure block 43 is driven to rise and fall by the hydraulic cylinder 42, so as to realize the clamping and disassembly of the steel plate. During the drilling work, larger debris or clumped waste debris can roll down into the blanking port along the inclined workbench bottom plate 11; smaller debris or powder is adsorbed on the workbench bottom plate 11 and can be cleaned by the dust blowing gun 7. The chips are blown into the material outlet; the inclined workbench bottom plate facilitates the chips to slide into the bottom material outlet, and are transported and discharged to the outside of the drilling machine through the chip conveyor at the bottom, so as to avoid the strip-shaped chips and waste materials being entangled on the drill bit of the drilling machine, thereby ensuring the processing safety. At the same time, there is a dust blowing gun, which can blow the accumulated and adhered chips into the material outlet after the drilling work is completed, thereby ensuring the cleanliness of the workbench, facilitating maintenance, and helping to extend the service life of the equipment. The chips are transported by the conveyor belt, with high transportation efficiency, and the chips are not easy to scatter, thereby reducing the cleaning work in the workshop.
