DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the utility model provides a technical solution: an automobile parts bending mold, comprising a base 1, a lower mold 11 is installed on the top of the base 1, a top plate 12 is installed on the upper side of the base 1 through a support rod, and a hydraulic rod 16 is installed on the top of the top plate 12, the output end of the hydraulic rod 16 passes through the top plate 12 and is connected to an upper mold 13, V-shaped strips 14 are fixedly installed on both sides of the top of the lower mold 11, and a V-shaped plate 15 is installed between two groups of V-shaped strips 14. This structure enables the automobile parts to be processed so that the automobile parts can be bent and formed, and the base 1 is installed on both sides for limiting the parts. The calibration component 2 comprises a movable groove 21 and a fixing bolt 25. The movable groove 21 is provided at the side end of the base 1. A movable plate 22 is slidably installed in the movable groove 21, and a top side of the movable plate 22 is fixedly connected to a limiting plate 23. A scale line 24 is engraved at one end of the movable plate 22. The fixing bolt 25 is installed at one side of the base 1. The movable plate 22 is locked in the movable groove 21 by the fixing bolt 25. This structure can limit the position of the automobile accessories, so that the automobile accessories can be placed on the V-shaped plate 15 for processing and can be more stable, making it less likely to deviate during bending.

[0023] As an implementation method in this embodiment, Figure 4 and Figure 5 As shown, a disassembly and assembly mechanism for replacing the V-shaped plate 15 is installed between the V-shaped plate 15 and the two groups of V-shaped strips 14. The disassembly and assembly mechanism includes a disassembly and assembly component 3 for disassembling and installing the V-shaped plate 15 and a locking component 4 for locking the disassembly and assembly component 3. The disassembly and assembly component 3 includes a slide groove 31 and a limit groove 34. The slide groove 31 is arranged at one end of the two groups of V-shaped strips 14 close to each other. A spring 32 is installed on the inner side of the slide groove 31. A slider 33 is slidably installed at the opening of the slide groove 31. The two ends of the spring 32 are fixedly connected to the inner wall of the slide groove 31 and the inner end of the slider 33 respectively. The limit groove 34 is arranged at the two ends of the V-shaped plate 15 close to the V-shaped strip 14. The slider 33 is inserted into the slide groove 31. The slider 33 is arranged in the limiting groove 34, and the outer diameter of the end of the slider 33 is matched with the inner diameter of the limiting groove 34, so that the V-shaped plate 15 is installed more firmly and is not easy to shake. The inner end of the slider 33 is connected to the pull rod 35, and the pull rod 35 is locked by the locking assembly 4. This structure makes it possible to install and disassemble the V-shaped plate 15 without using tools, and the operation is simpler and more convenient, which greatly increases the practicality of the device. The outer end of the pull rod 35 passes through the spring 32 and extends to the outside of the V-shaped bar 14. The outer end of the pull rod 35 is installed with a handle 36. This structure makes it more convenient to pull the pull rod 35 through the handle 36, and it is also more comfortable to hold the handle 36.

[0024] As an implementation method in this embodiment, Figure 4 and Figure 5As shown, the locking assembly 4 includes a limiting sleeve 41 and a limiting hole 43. The limiting sleeve 41 is fixedly connected to the end of the V-shaped bar 14 away from the V-shaped plate 15. A sliding rod 42 is slidably installed in the limiting sleeve 41. The limiting hole 43 passes through the side end of the pull rod 35, and the sliding rod 42 is inserted in the limiting hole 43. This structure makes it possible to keep the slider 33 in the slide groove 31, so that it is more convenient to disassemble and install the V-shaped plate 15, which greatly increases the convenience of the device. A guide opening 44 is provided on the surface of the limiting sleeve 41, and a connecting rod 45 is fixedly connected to the side of the surface of the sliding rod 42 away from the pull rod 35, and the connecting rod 45 slides in the guide opening 44. This structure makes it more convenient to push and pull the sliding rod 42 to slide in the limiting sleeve 41 through the connecting rod 45.

[0025] Working principle: If you need to bend an automobile part, you only need to place the automobile part on the V-shaped plate 15, and then adjust the distance between the limiting plate 23 and the part according to the width of the part. You only need to pull the limiting plate 23 to drive the movable plate 22 to slide in the movable groove 21. At the same time, by observing the scale line 24, make the distance between the two sets of limiting plates 23 and the lower mold 11 equal. Finally, tighten the fixing bolts 25 to fix the movable plate 22. In this way, the part can be limited. Then start the hydraulic rod 16 to drive the upper mold 13 to move downward until the part is bent into shape.

[0026] In addition, if the V-shaped plate 15 needs to be replaced, it is only necessary to hold the handle 36 and pull it outward, so that the handle 36 drives the pull rod 35, and the pull rod 35 drives the slider 33, so that the slider 33 moves out of the limiting groove 34, until the slider 33 is completely moved into the slide groove 31 and the spring 32 is compressed, and at the same time, the pull rod 35 will also bring the limiting hole 43 out of the slide groove 31, then the connecting rod 45 can be pushed to slide in the guide opening 44, and the connecting rod 45 drives the slide rod 42 to slide in the limiting sleeve 41 until the slide rod 42 is aligned with the limiting hole 43 and inserted, so that the slider 33 can be locked in the slide groove 31 by the pull rod 35. The V-shaped plate 15 can be disassembled by locking several groups of sliders 33 in the slide grooves 31 in turn. If a new V-shaped plate 15 needs to be installed, the V-shaped plate 15 only needs to be placed between the two groups of V-shaped bars 14, and the limiting grooves 34 are aligned with the sliders 33. Then, the connecting rods 45 are pulled in reverse in turn to drive the sliders 42 to move until the sliders 42 are pulled out of the limiting holes 43. At this time, the pull rod 35 will lose its limit, and the slider 33 will also lose its limit. In this way, the slider 33 can be pushed into the limiting groove 34 by the restorative elastic force of the slide groove 31, and the V-shaped plate 15 can be installed and fixed.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
