Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and more specifically, to an automatic flaring device for automotive shock absorber conduits. Background Technology

[0002] The shock absorber guide is a key component of the shock absorber system, primarily used to transmit hydraulic oil or gas to ensure the normal operation of the shock absorber. The main purpose of flaring the shock absorber guide is to ensure the sealing performance of the pipe joint. Flaring is an important step in the shock absorber manufacturing process. Its core function is to change the shape of the guide end to form a tighter and more reliable sealing surface with the connecting components. When the shock absorber is working, the internal oil flows through small holes or gaps to generate damping force. The flared guide design optimizes the oil flow path, reduces the risk of leakage, and thus ensures the stability of the damping force and the shock absorption effect.

[0003] However, existing automatic flaring devices for automotive shock absorber guides lack a measuring structure when placing the shock absorber guide, resulting in the flaring end of the guide not being accurately placed in the mold cavity flaring end. This leads to the flaring end of the guide being placed too long or too short, thus affecting the flaring accuracy. Therefore, we propose an automatic flaring device for automotive shock absorber guides to solve the above-mentioned problems. Utility Model Content

The lower mold base has symmetrical guide rails mounted on the base on one side. A connecting seat is mounted above the guide rail. A slide block that is slidably connected to the guide rail is mounted at the bottom of the connecting seat. An expansion joint is mounted on the surface of the slide block near the lower mold base.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figure 1-3 An automatic flaring device for automotive shock absorber guide tubes includes a base 1, a lower mold base 2 fixed on the base 1, and an upper mold base 3 installed above the lower mold base 2. The front end of the upper mold base 3 is provided with an assembly hole 6, and a scale 8 is inserted into the inner side of the assembly hole 6. The top of the upper mold base 3 is provided with a threaded hole 7 that is in communication with the assembly hole 6, and a locking bolt 10 that tightly abuts against the scale 8 is screwed into the inner side of the threaded hole 7. The zero mark of the scale 8 is detachably connected to the scale 9; A support frame 11 is fixedly connected to the edge of the base 1, and a first hydraulic cylinder 12 with its movable end connected to the upper mold base 3 is installed on the support frame 11. A guide rail 13 is symmetrically arranged on one side of the lower mold base 2 and mounted on the base 1. A connecting seat 14 is installed above the guide rail 13. A slide seat 15 that is slidably connected to the guide rail 13 is installed at the bottom of the connecting seat 14. An expansion mouth 16 is installed on the surface of the slide seat 15 near the lower mold base 2. A second hydraulic cylinder 17 with its movable end connected to the connecting seat 14 is installed on one side of the guide rail 13 through a bracket. It should be noted that when using this automatic flaring device for automotive shock absorber guides, the scale 8 is inserted into the inner side of the assembly hole 6, and the flaring length of the shock absorber guide is measured by the scale 8 protruding from the assembly hole 6. The scale 8 is locked by the locking bolt 10 installed in the threaded hole 7. Then, the scale 9 is installed at the zero mark of the scale 8, and the shock absorber guide is installed in the mold cavity of the lower mold base 2. After its end abuts against the scale 9, the first hydraulic cylinder 12 installed on the support frame 11 is controlled to drive the upper mold base 3 to press down and remove the scale 9. The shock absorber guide can be accurately placed at the flaring end of the mold cavity to ensure the precision of the flaring length. Then, the movable end of the second hydraulic cylinder 17 is controlled to push the connecting seat 14, so that the slide 15 slides in conjunction with the guide rail 13, thereby making the flared end 16 abut against the opening of the shock absorber guide tube, and flaring the opening of the shock absorber guide tube under pressure, thus realizing the automatic flaring of the automobile shock absorber guide tube.

[0019] like Figure 2 , Figure 3 As shown, guide posts 4 are symmetrically fixedly connected to the upper surface edge of the lower mold base 2, and guide holes 5 are opened at the edge of the upper mold base 3 to slide and connect with the guide posts 4. It should be noted that the guide hole 5 cooperates with the guide post 4 to slide, thereby ensuring the accuracy of mold closing between the lower mold base 2 and the upper mold base 3.

[0020] like Figure 2 As shown, the zero mark of the scale 8 has a slotted hole for inserting the scale 9, and the top of the scale 9 has an integrally formed limiting boss that abuts against the scale 8. It should be noted that by installing the scale 9 in the slotted hole of the scale 8, and by using the limiting boss to limit the scale 9, it is convenient to install and remove the scale 9.

[0021] like Figure 1 , Figure 5 As shown, a shock absorber conduit is installed between the mold cavities of the lower mold base 2 and the upper mold base 3. The end of the flared mouth 16 is provided with a chamfer, and the small circle diameter of the chamfer is smaller than the inner diameter of the shock absorber conduit. The outer diameter of the flared opening 16 is larger than the inner diameter of the shock absorber duct; It should be noted that the centerline of the flared end 16 is on the same straight line as the centerline of the shock absorber conduit, which facilitates the connection between the flared end of the flared end 16 and the opening of the shock absorber conduit, and is beneficial to the flaring operation of the shock absorber conduit.

[0022] like Figure 1 As shown, gear pumps 18 that provide power to the first hydraulic cylinder 12 and the second hydraulic cylinder 17 are installed on both sides of the connecting seat 14. It should be noted that the first hydraulic cylinder 12 and the second hydraulic cylinder 17 are powered by the gear pump 18, and their extension and retraction, as well as the degree of extension and retraction, are controlled by the control structure such as the pressure valve, flow valve, and controller.

[0023] In use: By inserting the scale 8 into the inside of the assembly hole 6 and using the scale 8 protruding from the assembly hole 6 to measure the flared length of the shock absorber guide tube, the scale 8 is locked by installing the locking bolt 10 in the threaded hole 7. Then, the scale 9 is installed at the zero mark of the scale 8, and the shock absorber guide tube is installed in the mold cavity of the lower mold base 2. After its end abuts against the scale 9, the first hydraulic cylinder 12 installed on the support frame 11 is controlled to drive the upper mold base 3 to press down and remove the scale 9. The shock absorber guide tube can be accurately placed at the flared end of the mold cavity to ensure the precision of the flared length. Then, the movable end of the second hydraulic cylinder 17 is controlled to push the connecting seat 14, so that the slide 15 slides in conjunction with the guide rail 13, thereby causing the flared end 16 to come into contact with the opening of the shock absorber guide tube, and the opening of the shock absorber guide tube is flared under pressure.

[0024] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
