Description

Technical Field

[0001] This application relates to the field of stabilizer bar cutting technology, and in particular to a stabilizer bar cutting device. Background Technology

[0002] Stabilizer bars are used to stabilize a car when cornering or driving on bumpy roads, and their application in car chassis is becoming increasingly widespread. Stabilizer bars are divided into hollow and solid types. The traditional method of cutting them mainly involves using a conventional cutting machine. However, this method is inefficient, and cutting residue is left on the surface of the stabilizer bar during the cutting process, requiring manual cleaning later, which is relatively troublesome. Therefore, this application proposes a new technical solution. Utility Model Content

[0003] To improve cutting efficiency, this application provides a stabilizer bar cutting device.

[0004] This application provides a stabilizer bar cutting device, which adopts the following technical solution:

[0005] A stabilizer bar cutting device includes a bar cutting mechanism, a support mechanism located below the bar cutting mechanism, and a cutting blade assembly. The bar cutting mechanism includes a first mold base and a pad, the pad being detachably connected to the first mold base. The support mechanism includes a second mold base and a fixing plate, the second mold base and the fixing plate being connected. A guide post assembly for guiding displacement is provided between the first mold base and the second mold base. The cutting blade assembly includes a first cutter, a second cutter, and a limiting plate for placing and limiting the stabilizer bar. The first cutter and the second cutter are staggered in plan view. The first cutter is connected to the pad, the second cutter is connected to the fixing plate, and the limiting plate is fixed to the fixing plate and located to the side of the first cutter and the second cutter.

[0006] Optionally, both the first and second cutters have arc-shaped cutting grooves on their blades. The first cutter includes at least two specifications for replacement. The bottom of the cutting groove is arc-shaped and matches the curvature of the outer wall of the stabilizer bar. In one type of first cutter, the bottom depth of the cutting groove is greater than the depth of the cutting groove of the other type of first cutter. The groove wall extends in an arc towards the groove opening, and the distance between the two groove walls decreases from the groove opening to the groove bottom. The side wall of the stabilizer bar is close to the groove wall.

[0007] Optionally, the guide post assembly includes a sleeve and a guide post, one end of the sleeve is fitted and slidably connected to the guide post, the other end of the sleeve is fixed to the first mold base, and the sleeve slides vertically along the guide post.

[0008] Optionally, the fixing plate includes an integrally formed positioning key, the second cutter is fixed to the positioning key, the positioning key is located below the pad, and when the pad abuts against the positioning key, the first cutter and the second cutter cut off the stabilizing rod.

[0009] In summary, this application includes the following beneficial technical effects: when it is necessary to cut the stabilizer bar, the stabilizer bar is inserted into the slot on the limit bar, and the first mold base drives the pad block and the first cutter to cut downward. While cutting the stabilizer bar, the use of mold punching to cut the material can reduce the amount of debris left on the surface of the bar, thereby reducing the need for manual wiping of the stabilizer bar.

[0013] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0014] This application discloses a stabilizer bar cutting device.

[0015] Reference Figure 1 The stabilizer bar cutting device includes a bar cutting mechanism 1, a support mechanism 2 located below the bar cutting mechanism 1, and a cutting blade assembly 3. The bar cutting mechanism 1 includes a first mold base 11 and a pad 12. The first mold base 11 can be rectangular in plan view, located at the top of the device, and is used to fix the pad 12. The first mold base and the pad 12 can be connected by bolts. The support mechanism 2 includes a second mold base 21 and a fixing plate 22. The second mold base 21 and the fixing plate 22 are detachably connected by bolts. The second mold base 21 is located below the first mold base 11, and the two are connected by a guide post assembly 4 to guide their vertical displacement.

[0016] The cutting assembly 3 includes a first cutting blade 31, a second cutting blade 32, and a limiting plate for placing and limiting the stabilizing rod. The first cutting blade 31 is fixed to the pad 12 by bolts, and the second cutting blade 32 is fixed to the fixing plate 22 by bolts, thereby enabling quick switching of the cutting blades. The first cutting blade 31 and the second cutting blade 32 are staggered, that is, when viewed from above, the first cutting blade 31 is located to the side of the second cutting blade 32. Both the cutting edges of the first cutting blade 31 and the second cutting blade 32 are provided with arc-shaped cutting rod grooves 34. The side wall of the stabilizing rod fits exactly with the curvature of the cutting rod grooves 34, so that when the cutting blade cuts the stabilizing rod, the force on the stabilizing rod can be more even and less prone to deformation. When the first mold base 11 moves downward along with the pad 12 and the first cutting blade 31, the first cutting blade 31 moves up and down to the side of the second cutting blade 32 and cuts off the stabilizing rod.

[0017] The limiting plate is fixed to the fixing plate 22 by bolts and is located on the side of the first cutter 31 and the second cutter 32. The limiting plate has a circular slot along the thickness direction. The stabilizing rod is inserted and penetrates the slot. After the stabilizing rod is placed on the limiting plate, the first cutter 31 and the second cutter 32 cooperate to cut off the stabilizing rod.

[0018] With the above settings, when it is necessary to cut the stabilizer bar, insert the stabilizer bar into the slot on the limit bar 33, and the first mold base 11 will drive the pad block 12 and the first cutter 31 to cut downward. While cutting the stabilizer bar, the use of mold punching to cut the material can reduce the amount of debris left on the surface of the bar, thereby reducing the need for manual wiping of the stabilizer bar.

[0019] Reference Figure 2 The first cutter 31 includes at least two specifications. In one specification, the cutting groove 34 of the first cutter 31 has a greater depth from the opening to the bottom, and the groove wall extends in an arc towards the opening. The distance between the two sides of the groove wall decreases from the opening to the bottom, meaning the distance between the two sides of the groove wall is the greatest at the opening and gradually decreases as it approaches the bottom, allowing the stabilizing rod to be close to the groove wall. Based on this configuration, when the first cutter 31 cuts from top to bottom, if the stabilizing rod is hollow, its two sides may be squeezed to the sides. However, the groove wall's restraint helps to reduce the deformation of the stabilizing rod.

[0020] Referring to Figure 1, the guide post assembly 4 includes a sleeve 41 and a guide post 42. One end of the sleeve 41 is slidably connected to the guide post 42. The sleeve 41 may be equipped with a reset device (such as a reset spring) or a hydraulic cylinder. The telescopic end of the hydraulic cylinder may be fixed to the first mold base 11, so that the first mold base 11 can be reset after being pressed down and continue to perform the cutting action.

[0021] According to the above configuration, the sleeve 41 and the guide post 42 cooperate to further prevent the first cutter 31 and the second cutter 32 from being misaligned or offset when cutting the stabilizer bar, thereby further ensuring the accuracy of cutting the stabilizer bar.

[0022] Reference Figure 1 The fixing plate 22 includes an integrally formed positioning key. The second cutter 32 is fixed to the positioning key by bolts, which facilitates the replacement and disassembly of the cutter. The positioning key is located below the pad 12. When the first mold base 11 presses down and pushes the first cutter 31 downward to cut the stabilizing rod, the pad 12 and the positioning key abut against each other, thereby effectively preventing the first cutter 31 from cutting too much and limiting the cutting action of the first cutter 31.

[0023] This application also discloses a method for cutting stabilizer bars.

[0024] The method for cutting stabilizer bars includes the following steps:

[0025] S1. Mold assembly, which includes:

[0026] Select the appropriate first cutter 31, second cutter 32, or positioning key, limit plate, etc., according to the diameter of the stabilizer bar to be cut, and replace or install them. If cutting a hollow stabilizer bar, select the first cutter 31 with a deeper cutting groove 34 for cutting.

[0027] S2, Cutting stabilizer bar, which includes:

[0028] After assembling the mold, pass the stabilizer bar through the hole in the limiting plate, press the first mold base 11, push the first cutter 31 down, and cut the stabilizer bar.

[0029] S3. Post-cutting work, which includes:

[0030] Remove the cut stabilizer bar and check for deformation, and remove any burrs.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
