DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 - Figure 8 The anti-collision pipe bending device for electric vehicles shown in the figure includes an operating table 1, a bending machine body 2, a main clamp 3 and a rotatable auxiliary clamp 4. The bending machine includes a main clamp 3 and an auxiliary clamp 4. The anti-collision tube 24 is placed on the inner walls of the main clamp 3 and the auxiliary clamp 4. The anti-collision tube 24 is bent by driving the auxiliary clamp 4 to rotate. It is an existing conventional technical means and is widely used, so it will not be described in detail here.

[0025] The bending machine body 2 is fixedly arranged on the surface of the operating table 1, the main clamp 3 is fixedly arranged on the top of the bending machine body 2, the auxiliary clamp 4 is rotatably arranged on one side of the fixed clamp, and a plurality of auxiliary bending parts 5 are rotatably arranged on the inner wall of the auxiliary clamp 4 at equal intervals, a rotating disk 6 is rotatably arranged on the surface of the main clamp 3, and the upper end of the auxiliary clamp 4 is fixed to the rotating disk 6, and an electric push rod 7 for driving the rotating disk 6 to rotate is fixedly arranged on one side of the bending machine body 2, and the protruding end of the electric push rod 7 is rotatably connected to the rotating disk 6.

[0026] First, place the anti-collision tube 24 between the main clamp 3 and the auxiliary clamp 4. Then, start the electric push rod 7, extend the protruding end, and synchronously drive the rotating disk 6 to start rotating, driving the auxiliary bending part 5 in the auxiliary clamp 4 to be close to the outer wall of the anti-collision tube 24. As the rotating disk 6 continues to rotate, the auxiliary bending part 5 rotates along the outer contour of the anti-collision tube 24, thereby realizing the bending of the anti-collision tube 24.

[0027] A lubrication component is provided on the auxiliary clamp 4 for adding lubricating oil when the anti-collision tube 24 is bent. When the auxiliary clamp 4 is in close contact with the anti-collision tube 24 and bends, the auxiliary bending part 5 rotates accordingly, and uses the kinetic energy of its rotation to automatically apply an appropriate amount of lubricating oil to the contact area without manual intervention, effectively avoiding the problems of excessive, insufficient or uneven distribution, not only reducing the friction and wear between the auxiliary bending part 5 and the anti-collision tube 24, but also significantly reducing the quality problems such as cracking or extrusion marks of the anti-collision tube 24 caused by insufficient lubrication, thereby improving the efficiency of the bending operation and the quality of the finished product.

[0028] The lubrication assembly includes a rotating rod 8, which is fixedly arranged on the top of the auxiliary bending part 5 through a one-way gear. A plurality of storage tanks 9 are equidistantly fixedly arranged on the top of the auxiliary clamp 4. The storage tanks 9 are used to store lubricating oil. A rotating shaft 10 is rotatably arranged on the inner wall of the storage tank 9. A screw 11 is fixedly arranged at the bottom of the rotating shaft 10. A piston 12 is threadedly connected to the screw 11 through a threaded hole. The piston 12 is slidably connected to the inner wall of the storage tank 9. A discharge pipe 13 is connected to one side of the storage tank 9. The discharge pipe 13 passes through the auxiliary clamp 4 toward the auxiliary bending part 5. A driving gear 14 is fixedly arranged on the top of the rotating rod 8, and a driven gear 15 is fixedly arranged on the top of the rotating shaft 10. The driving gear 14 is meshed with the driven gear 15.

[0029] The extended end of the push rod is extended by driving, and the extended end rotates with the rotating disk 6, and the rotating disk 6 rotates while the auxiliary clamp 4 rotates, and the auxiliary clamp 4 rotates with the rotating rod 8, and the rotating rod 8 rotates with the driving gear 14, and the driving gear 14 drives the driven gear 15 to rotate, and the driven gear 15 rotates to rotate the rotating shaft 10, and the rotating shaft 10 rotates with the screw 11, and the rotation of the screw 11 causes the piston 12 to slide downward along the inner wall of the storage tank 9 and squeeze the lubricating oil, so that the lubricating oil flows out of the discharge pipe 13 and drips on the connection between the anti-collision pipe 24 and the auxiliary bending part 5, thereby achieving a lubricating effect;

[0030] After the anti-collision tube 24 is bent, the extended end of the electric push rod 7 is driven to retract, and the extended end is reset with the rotating disk 6. At this time, the auxiliary clamp 4 is rotated and reset with the auxiliary bending part 5. At this time, when the auxiliary bending part 5 rotates in the opposite direction, it is affected by the one-way gear. At this time, the rotating rod 8 is idle, and the rotating rod 8 does not rotate with the driving gear 14. When the piston 12 rotates to the lowermost end of the screw 11, the piston 12 can be reset by rotating the driven gear 15.

[0031] Furthermore, considering that the discharge pipe 13 is in the downward direction, the lubricating oil in the discharge pipe 13 will flow out when the auxiliary bending part 5 is not working. An opening and closing leaf 21 is rotatably provided on the inner wall of the end of the discharge pipe 13 away from the storage tank 9. The opening and closing leaf 21 is sealed with the inner wall of the discharge pipe 13 by a sealing ring. A torsion spring 22 is sleeved on the opening and closing leaf 21. One end of the torsion spring 22 is fixed to the inner wall of the discharge pipe 13. The lubricating oil is mainly squeezed from the storage tank 9 into the discharge pipe 13 by the extrusion of the piston 12, and the lubricating oil opens the opening and closing leaf 21 and compresses the torsion spring 22 through the extrusion of the piston 12, so that the lubricating oil drips from the discharge pipe 13 to the contact side of the anti-collision tube 24 and the auxiliary bending part 5. When the auxiliary bending assembly stops rotating, the piston 12 stops squeezing the lubricating oil downward, and at this time, the torsion spring 22 recovers its deformation and pushes the opening and closing leaf 21 to reset, thereby sealing the lubricating oil in the discharge pipe 13.

[0032] Furthermore, considering that the lubricating oil dripping on the connection between the anti-collision tube 24 and the auxiliary bending part 5 will drip onto the operating table 1, the lubricating oil can also be recycled for secondary use. A recycling component for recycling the lubricating oil is provided on the surface of the bending machine body 2, which can recycle the lubricating oil dripping on the connection between the anti-collision tube 24 and the auxiliary bending part 5, and filter other impurities in the recycled lubricating oil to make the lubricating oil purer, and the recycled lubricating oil can also be replenished in the storage tank 9;

[0033] The recycling component includes a recycling box 16, and a filter screen 17 is slidably provided on the inner wall of the recycling box 16. Considering that the filter screen 17 needs to be replaced after long-term use, a drawer box 23 is slidably provided on one side of the recycling box 16. When the filter screen 17 needs to be replaced, it is only necessary to pull out the drawer box 23 to pull out the old filter screen 17 and replace it with a new filter screen 17. The operation is simple.

[0034] The filter screen 17 is fixedly arranged on the inner wall of the extraction box 23, and the inner wall of the recovery box 16 is fixedly arranged with a pump body 18, one end of the pump body 18 is connected with a delivery pipe 19, and the delivery pipe 19 passes through the recovery box 16 and is connected with the storage tank 9, and the storage tanks 9 are connected with a feeding pipe 20. The lubricating oil dripping into the recovery box 16 will first contact the filter screen 17, and the impurities in the lubricating oil will be blocked by the filter screen 17, and the filtered lubricating oil will drip into the recovery box 16, and the lubricating oil will be drawn into the delivery pipe 19 and delivered to the storage tank 9 by driving the pump body 18, and the lubricating oil delivered to the storage tank 9 can be squeezed by the piston 12 so that the lubricating oil can be sequentially sent into the storage tank 9 through the feeding pipe 20 to replenish the lubricating oil.
