Description

Technical Field

[0002] Before forging, the end of the hollow stabilizer bar needs to be heated to the austenitizing temperature (800℃-1150℃) and then forged. After forging, it is usually air-cooled to room temperature to obtain pearlite and ferrite structures, which can meet the fatigue life requirements of the product. However, a small number of stabilizer bar ends have large stresses (≥400MPa). Conventional air cooling treatment cannot meet the fatigue life requirements of the vehicle and there is a risk of fracture. Heat treatment is required to obtain martensite structure to improve the strength and toughness of the end to meet fatigue requirements.

With respect to the above-mentioned related technologies, the inventor believes that the clamp is opened and closed and clamped by the cylinder, and the end is sprayed and quenched by the nozzle at this time, so that it is necessary to wait for the quenching of the previous group of stabilizer rods to be completed, remove the quenched stabilizer rods, and then clamp the next group of stabilizer rods for subsequent quenching, resulting in the low efficiency of the entire quenching process.

[0024] See also Figure 1-4A cooling device for the end of a hollow stabilizer rod comprises a conveying mechanism 1, wherein the conveying mechanism 1 comprises two sets of cross beams 101 arranged symmetrically, and the bottoms of the two sets of cross beams 101 are symmetrically fixedly connected with connecting plates 103, and the setting of the cross beams 101 is used to provide support for the connecting plates 103. The opposite sides of the two sets of connecting plates 103 are symmetrically connected with first sprocket wheels 104, and the bottoms of the two sets of connecting plates 103 are symmetrically fixedly connected with hanging plates 105, and the opposite sides of the hanging plates 105 on both sides are rotatably connected with second sprocket wheels 106, and the setting of the hanging plates 105 is used to provide support for the second sprocket wheels 106. The second sprocket wheels 106 on the same side are meshedly connected with the outer sides of the hanging plates 105, and the setting of the second sprocket wheels 106 can guide the chain 107.

[0025] The bottoms of the two groups of cross beams 101 are symmetrically fixedly connected with columns 102, and the setting of the columns 102 can support the cross beams 101. The outer side of each group of columns 102 is provided with a threaded groove 208, and the bottom of each group of columns 102 is threadedly connected with an internal threaded tube 207. The bottoms of the two groups of internal threaded tubes 207 on the same side are rotatably connected with the bottom beam 202. When the internal threaded tube 207 rotates, it can drive the columns 102, the cross beam 101 and each group of hooks 109 to move up and down synchronously, so as to adjust the height of the end of the transported hollow stabilizer rod. The opposite sides of the two groups of connecting plates 103 are fixedly connected with motors 110, and the output ends of the two groups of motors 110 are respectively fixedly connected to the first sprocket 104 on one side, and the motor 110 is used to drive the first sprocket 104 to rotate when it is working.

[0026] A plurality of cross bars 108 are evenly and fixedly connected between the two groups of chains 107, and the arrangement of the cross bars 108 can rotate with the rotation of the chains 107. The outer sides of each group of cross bars 108 are symmetrically rotatably connected with hooks 109, and the hooks 109 are arranged to hook the hollow stability rod, so that when the chains 107 drive the cross bars 108 to rotate, the hooks 109 can rotate cyclically, thereby realizing the conveyance of the hooked hollow stability rod. Quenching and cooling mechanism 2 The quenching and cooling mechanism 2 includes two groups of quenching boxes 201 symmetrically arranged below the crossbeam 101, and the quenching boxes 201 are arranged to contain quenching oil, so that the end of the hollow stability rod can be conveyed to the inside of the quenching box 201 through the conveyance of the chain 107 and the guidance of the second sprocket 106, so as to contact with the quenching oil inside the quenching box 201, thereby realizing the quenching treatment of the end of the hollow stability rod.

The setting of the collecting trough 212 can catch the quenching oil dripping after quenching. A guide rod 209 is provided on one side above the two groups of quenching boxes 201. The two groups of guide rods 209 are symmetrically arranged. The setting of the guide rod 209 can guide the hollow stability rod being transported, so as to adjust the hollow stability rod to the center, thereby ensuring that the ends of the two sides of the hollow stability correspond to the quenching boxes 201 on both sides. The bottoms of the two groups of guide rods 209 are fixedly connected to support rods 210. The two groups of support rods 210 are fixedly connected to the two groups of quenching boxes 201 respectively. The setting of the support rods 210 can support the guide rods 209.

[0028] The two groups of bottom beams 202 are symmetrically fixedly connected with sliding rods 203, and the outer sides of the two groups of sliding rods 203 are symmetrically slidably connected with sliding seats 204. The sliding seats 204 on both sides are respectively fixedly connected with the quenching boxes 201 on both sides. The arrangement of the sliding rods 203 and the sliding seats 204 can facilitate the adjustment of the spacing between the two groups of quenching boxes 201, so as to adapt to the end cooling treatment of hollow stability rods of different widths. The outer sides of the two groups of sliding rods 203 are slidably connected with sliding blocks 205, and the two groups of sliding blocks 205 are respectively fixedly connected with the sliding seats 204 on both sides.

When the limiting bolts 206 are screwed until they are tightly pressed against the sliding rods 203, they can limit the sliding blocks 205 and the quenching box 201, so as to limit the probability of the quenching box 201 moving.

[0029] When in use, the quenching boxes 201 on both sides are slid, thereby driving the guide rods 209 on both sides to move relative to each other, until the spacing between the two groups of guide rods 209 is adjusted to be consistent with the width of the stabilizer bar to be processed, and then the quenching oil is introduced into the interior of the two groups of quenching boxes 201, and then the two groups of motors 110 are started, thereby driving the two groups of first sprockets 104 and chains 107 to rotate synchronously, and then driving each group of cross bars 108 and each group of hooks 109 to rotate accordingly, and then the hollow stabilizer bar to be processed is hooked on the hook 109 on the side away from the guide rod 209, so that the hollow stabilizer bar can be transported from one side to the other side, and when the hollow stabilizer bar passes between the guide rods 209 on both sides, the guide rods 209 on both sides can guide the stabilizer bar, so that the stabilizer bar The rod can be guided to be centered, and the ends on both sides of the guide rod can correspond to the quenching boxes 201 on both sides. When the end of the stabilizer rod is transported to the inside of the quenching box 201, it can contact the quenching oil inside the quenching box 201, thereby realizing quenching and cooling of the end of the stabilizer rod. The chain 107 drives the hook 109 to move at any time, so that the quenched rear end is transported out of contact with the quenching oil inside the quenching box 201 until it is transported to the top of the guide rod 209, and then the hollow stabilizer rod after the groove quenching treatment can be removed from the corresponding hook 109, so that the hollow stabilizer rod to be processed can be continuously placed in the hook 109 from one side, and the processed hollow stabilizer rod can be continuously removed from the other side to realize flow operation.
