Description

Technical Field

[0001] This invention relates to the field of residential building construction technology, specifically to a bending device for processing steel bars in residential construction. Background Technology

[0002] Residential buildings, as the name suggests, are buildings for family living. The construction of residential buildings requires the use of concrete and steel bars. When using steel bars, it is necessary to bend steel bars of different diameters to facilitate the assembly of steel cages.

[0003] In existing steel bar bending devices, a high-torque motor drives a transmission gear to rotate a worm gear inside the drive box. The worm gear then drives a turbine and a rotating spindle within the drive box to rotate, thus completing the reciprocating bending operation of the steel bar placement disc. However, the drive box of existing steel bar bending machines is often fixedly connected to the processing panel through numerous bolts, and the rotating spindle also needs to be connected through the processing panel. After prolonged use, this connection method allows a large amount of rainwater to seep into the drive box from the spindle connection and bolt holes, potentially causing the original lubrication within the drive box to fail, affecting the service life of the worm gear and turbine, and making it inconvenient to use.

[0040] Example 4

[0041] Based on Embodiment 3, a lubricating oil lifting operation is performed. The lubrication assembly is located at the lower center of the drive box 2. The lubrication assembly includes an oil cylinder 33 and a top oil seat 21. The lower end of the drive box 2 is tapered, and a threaded groove is opened through the center of the lower end of the drive box 2. The oil cylinder 33 is vertically inserted into the threaded groove, and a sealing gasket is fitted on the side of the oil cylinder 33 that is inserted into the threaded groove. A push tube 18 is vertically provided at the lower end of the bearing seat 7. The center of the push tube 18 passes through the rotating seat 6 and the center of the connecting column 12, and a conveying groove 19 is opened. The top oil seat 21 is vertically located at the lower center of the oil cylinder 33. A top oil groove is opened at the lower end of the top oil seat 21, and four replenishment grooves are opened through the top oil seat 21 on the four sides of the top oil groove. 22. A spring groove is provided at the upper end of the top oil seat 21. A prismatic rod 23 is vertically inserted between the spring groove and the top oil groove. A first piston 24 and a pressing block 25 are respectively provided in the top oil groove and the spring groove of the prismatic rod 23. A return spring 26 is sleeved on one side of the prismatic rod 23 in the spring groove. An inlet tube 27 is vertically provided at the upper end of the pressing block 25. The upper end of the inlet tube 27 is movably inserted into the lower end of the conveying groove 19 of the push tube 18 and is movably sleeved with a second piston 28. Two first protrusions 29 are symmetrically provided at the lower end of the push tube 18. Two second protrusions 30 are symmetrically provided at the upper end of the pressing block 25. Both sides of the first protrusions 29 and the second protrusions 30 are inclined surfaces. The inclined surfaces of protrusions 29 and 30 are arranged in relative contact. A one-way groove is formed in the center of the inlet pipe 27, passing through the extrusion block 25, the prismatic rod 23, and the first piston 24. A first one-way valve 31 is inserted into the lower end of the one-way groove, and a second one-way valve 32 is inserted into the lower end of the conveying groove 19. The descent length of the first piston 24 is greater than the height of the supplementary groove 22. When the drive worm gear 4 drives the turbine ring 8 to rotate, the turbine ring 8 controls the rotating seat 6 and the lower push pipe 18 to rotate. The push pipe 18 causes the two first protrusions 29 to make misaligned contact with the two second protrusions 30. Under the action of their inclined surfaces, the second protrusions 30, along with the extrusion block 25, are pressed downwards. At this time, the extrusion block 25 drives... The prism rod 23 presses the return spring 26, causing the lower end of the first piston 24 to pass over the replenishment groove 22 and continue to move downward. At this time, the oil cylinder 33 is filled with lubricating oil, and a certain amount of lubricating oil enters the top oil groove from the replenishment groove 22. As the first piston 24 passes over the replenishment groove 22, the lubricating oil in the top oil groove pushes the first one-way valve 31 to enter the one-way groove. The lubricating oil that enters the one-way groove will then enter the conveying groove 19 and push the second one-way valve 32 to continue to move upward, completing the lifting operation of the lubricating oil. After the first protrusion 29 and the second protrusion 30 pass their respective highest points, the first piston 24 quickly returns to its original position under the elastic action of the return spring 26, and the top oil groove is refilled with lubricating oil through the replenishment groove 22.

[0042] The oil cylinder 33 is a visible structure. An oil filter screen can be horizontally inserted into the upper end of the oil cylinder 33, and the lower end of the push tube 18 is set through the center of the oil filter screen.

[0043] Example 5

[0044] Based on Embodiment 4, lubrication is applied to the first and second bearings to improve the service life of the equipment. A diversion groove is provided at the upper end of the rotating seat 6, and support fork grooves 10 are provided at the upper ends of several welded arms 9. One side of each support fork groove 10 penetrates one side of the turbine ring 8. A drip hole 11 is vertically provided inside the rotating seat 6 near the first bearing. Two seepage grooves 20 are provided at the upper end of the conveying groove 19, penetrating both sides. The seepage grooves 20 are positioned between the bent disc 14 and the second bearing, allowing the lubricating oil entering the conveying groove 19 to continuously rise. After being lifted to the position of the seepage groove 20, the lubricating oil flows out naturally to lubricate the second bearing. After the second bearing is lubricated, the lubricating oil falls naturally or flows along the connecting column 12 into the diversion groove, and then flows further into the several support grooves 10. Then, when the turbine ring 8 rotates, the lubricating oil flowing out through the several support grooves 10 lubricates the meshing parts of the drive worm 4 and the turbine ring 8. In addition, the diversion groove is provided with an oil drip hole 11, which can directly flow out some lubricating oil to lubricate the first bearing, thereby improving the service life and convenience of the equipment.

[0045] Both the first check valve 31 and the second check valve 32 are common check valves used in oil and gas applications.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
