Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a hollow stabilizer bar heating and blowing device and a hollow stabilizer bar heating and constant temperature method. Background Art

[0002] The lateral stabilizer bar, also known as the anti-roll bar or balance bar, is an auxiliary elastic element in the automobile suspension.

[0003] During the use of the car, the function of the lateral stabilizer bar is to prevent the car body from excessive lateral tilt when turning, and to keep the car body balanced as much as possible. The purpose is to reduce the degree of lateral tilt of the car and improve ride comfort. The lateral stabilizer bar is actually a transverse torsion bar spring. When the car body only moves vertically, the deformation of the suspension on both sides is the same, and the lateral stabilizer bar does not work. When the car turns, the body rolls, and the suspension on both sides jumps inconsistently. The outer suspension will press against the stabilizer bar, and the stabilizer bar will twist. The elastic force of the bar body will prevent the wheel from lifting, so that the car body can be kept as balanced as possible, playing a role in lateral stability.

[0004] like Figure 1 As shown, due to the different suspension structures of different vehicle models, the stabilizer bar 10 that matches it needs to provide at least one bent rod section 13 between the connecting rod 12 and the straight cross bar 11 in order to adapt to the suspensions of different structures, so that the stabilizer bar 10 can avoid the components that hinder it and connect with the corresponding accessories.

[0005] However, due to the existence of the bent rod segment 13, when the stabilizer bar 10 is subjected to the resistance heating quenching process, given that the inner surface 131 and the outer surface 132 of the bent rod segment 13 have different strokes, the temperature rise rates when powered on at the same time will also be different. The inner surface 131 of the bent rod segment 13 is concave, and its heat dissipation surface is smaller than that of the convex outer surface 132. Therefore, the temperature of the inner surface 131 is often higher than that of the outer surface 132 during heating. The stabilizer bar 10 cannot ensure the uniformity of the heating temperature within the same heating time. The temperature difference between the inner surface 131 and the outer surface 132 of the rod is as much as 200°. The excessive temperature difference leads to uneven hardness of the parts after quenching, which greatly affects the product molding quality. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art, one of the objects of the present invention is to provide a hollow stabilizer rod heating and blowing device. By setting up a blowing mechanism, the stabilizer rod is cooled by jet during the heating process to ensure that the temperature difference between the inner and outer surfaces of the bent rod section is within a certain range, thereby improving the uniformity of the hardness of the stabilizer rod.

[0007] The second purpose of the present invention is to provide a method for heating and maintaining a constant temperature of a hollow stabilizer rod, monitor the temperature difference between the inner surface and the outer surface of the bent rod section, ensure that the temperature difference is within a controllable range by controlling the blowing mechanism, and ensure that the hardness of the stabilizer rod is uniform after quenching.

[0011] Furthermore, the nozzle has an air inlet end at one end and an air outlet end at the other end; an extension line of the air outlet end is tangent to the inner surface.

[0012] Furthermore, the hollow stabilizer rod heating and blowing device also includes a manifold; and the blowing mechanisms are all connected to the manifold air path.

[0013] Furthermore, the blowing mechanism also includes a gas diverter; the gas diverter has a plurality of diverter gas ports and an air inlet, the plurality of diverter gas ports are respectively connected to a plurality of the nozzle gas paths, and the air inlet of the gas diverter is connected to the manifold gas path.

[0014] Furthermore, the blowing mechanism also includes a positioning clamp for clamping the nozzle and an adjusting bracket; the positioning clamp is movably arranged on the adjusting bracket and can reciprocate between being away from and approaching the adjusting bracket.

[0015] Furthermore, the adjustment bracket includes a plurality of clamping blocks and a support rod; each of the clamping blocks is provided with at least two clamping holes, and the clamping holes are used to clamp the support rod so that the clamping block can be reciprocatedly adjusted along the extension direction of the support rod; the positioning clamp is extended with an adjustment rod, and the adjustment rod can be connected to any of the clamping holes.

[0016] Furthermore, the hollow stabilizing rod heating and blowing device also includes a bottom plate; the bottom plate is used for mounting and positioning the stabilizing rod and fixing the blowing mechanism.

[0017] Furthermore, a plurality of support plates are detachably arranged on the bottom plate; the support plates have brackets whose shapes match those of the stabilizing rods.

[0018] The second purpose of the invention is achieved by the following technical solution:

[0019] A method for heating and maintaining a constant temperature of a hollow stabilizer rod comprises the hollow stabilizer rod heating and blowing device as described above; the method for heating and maintaining a constant temperature of a hollow stabilizer rod comprises:

[0020] Stabilizer bar fixing step: installing and fixing the stabilizer bar;

[0021] The stabilizer bar that needs to be quenched is mounted and stabilized on an external tooling;

[0022] Temperature gun setup steps: Set the temperature gun to monitor the surface temperature of the stabilizer bar;

[0023] At least two temperature measuring guns are arranged on opposite sides of the curved rod section, and the two temperature measuring guns are used to monitor the surface temperature of the inner surface and the outer surface respectively;

[0024] Air blowing mechanism setting steps: The air blowing mechanism is set to cool the stabilizer bar;

[0025] The blowing mechanisms are provided in the same number as the bending rod segments, and are mounted on one side of the inner surface corresponding thereto, and the blowing mechanisms are connected to an external high-pressure gas source so that the high-pressure gas sprayed from the nozzles of the blowing mechanisms can pass through the inner surface corresponding thereto;

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] In view of the existence of the curved rod section of the lateral stabilizer bar used to avoid the suspension, and the problem of uneven temperature of the inner and outer surfaces of the curved rod section when powered on for heating, the present invention provides a blowing mechanism, and allows the gas blown out by the nozzle of the blowing mechanism to pass through the inner surface of the curved rod section. When the temperature difference between the inner and outer surfaces of the curved rod section exceeds 50° (usually the temperature of the inner surface is higher than that of the outer surface), the blowing mechanism is controlled to operate, allowing the nozzle to blow out high-pressure gas. After the high-pressure gas passes through the inner surface, the temperature of the inner surface is reduced, so that the temperature of the inner and outer surfaces of the curved rod section tends to be balanced, making the overall heating temperature of the stabilizer bar more uniform. When the temperature of the inner and outer surfaces returns to within 50°, the blowing mechanism is controlled to stop working.

[0034] A more uniform heating temperature of the stabilizer bar as a whole can make the hardness of the stabilizer bar more uniform during the quenching process, ensuring that the bar can stably play its role when put into use after heat treatment, thereby improving the quality of the finished product.

DETAILED DESCRIPTION

[0041] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0042] like Figures 1-2 As shown, in order to improve the hardness balance of the stabilizer bar 10 in the quenching process and improve the quality of the finished product, the present invention provides a heating and blowing device for a hollow stabilizer bar 10, which includes a stabilizer bar 10 and a blowing mechanism 20; the stabilizer bar 10 includes a straight cross bar 11, the straight cross bar 11 is used to be hinged with the frame, and both ends of the straight cross bar 11 are relatively extended with connecting rods 12, and the connecting rods 12 are respectively fixed on the left and right suspensions of the car. In actual use, when the vehicle body only moves vertically, the deformation of the suspensions on both sides is the same, and the stabilizer bar 10 does not work. When the vehicle body tilts, the vibrations of the suspensions on both sides are inconsistent, the stabilizer bar 10 twists, and the elastic force of the rod body becomes a resistance to continued tilting, thereby playing a role in lateral stability.

[0043] Due to the large number of current vehicle models, suspensions also have various structures. When the stabilizer bar 10 is installed on the suspension, the connecting rod 12 needs to avoid corresponding components during the extension process in order to achieve the purpose of connecting with both sides of the suspension. Therefore, the connecting rod 12 of the stabilizer bar 10 is connected to the straight cross bar 11 to form a curved rod segment 13, so that the arc between the connecting rod 12 and the straight cross bar 11 is transitional and has an included angle. Generally, a stabilizer bar 10 is provided with at least two symmetrical curved rod segments 13 on both sides. In this example, the stabilizer bar 10 has a total of four curved rod segments 13, which are mirror-symmetrically arranged at both ends of the straight cross bar 11; specifically, the curved rod segments 13 are arranged at the ends of the straight cross bar 11. The side of the curved rod segment 13 with a smaller average curvature radius forms an inner surface 131, and the side of the curved rod segment 13 with a larger average curvature radius forms an outer surface 132. The area of ​​the inner surface 131 of the curved rod segment 13 is smaller than that of the outer surface 132, and the inner surface 131 is concave, while the outer surface 132 is convex. Therefore, the heat dissipation area of ​​the inner surface 131 is smaller than that of the outer surface 132, and the power-on distance is shorter under the same power-on time, and the temperature rises faster. In the process of resistance heating, the temperature of the inner surface 131 is often 200° higher than the temperature of the outer surface 132, which seriously affects the hardness uniformity of the rod after the quenching process.

[0044] In order to solve the above problems, the blowing mechanism 20 corresponds to the bending rod segment 13 one by one. In this example, the stabilizing rod 10 has a total of four bending rod segments 13, so four groups of blowing mechanisms 20 are set corresponding to the bending rod segments 13. Each group of blowing mechanisms 20 corresponds to a bending rod segment 13 and performs jet heat dissipation on the corresponding bending rod segment 13. The blowing mechanisms 20 are connected to an external air source (not shown), preferably a high-pressure air source; the blowing mechanism 20 includes a nozzle 21 for blowing out gas, and the gas blown out by the nozzle 21 passes through the corresponding inner surface 131. By blowing and cooling the inner surface 131 of the stabilizing rod 10 being heated by the blowing mechanism 20, the temperature difference between the inner surface 131 and the outer surface 132 can be reduced, so that the overall temperature of the stabilizing rod 10 tends to be stable, meeting the process requirements of quenching, and the hardness of the rod is uniform after heat treatment, thereby improving the quality of the finished product.

[0045] Further, if Figures 3-4 As shown, in order to dissipate heat from the inner surface 131 of the curved rod segment 13 as a whole, the blowing mechanism 20 has a plurality of nozzles 21, and the plurality of nozzles 21 are arranged one by one along the corresponding inner surface 131 to ensure that the gas blown out by the nozzles 21 can cover the entire inner surface 131, thereby achieving a rapid cooling effect.

[0046] One end of the nozzle 21 has an air inlet end 211, which is connected to an external air source, and the other end has an air outlet end 212. In order to allow the gas blown out of the nozzle 21 to only cool down the inner surface 131 without allowing the gas to diffuse and affect the temperature of other parts of the stabilizing rod 10, the extension line of the air outlet end 212 is tangent to the inner surface 131. Preferably, several nozzles 21 are parallel to each other to ensure the uniformity of the ejected gas. The gas blown out of the nozzle 21 only passes through the inner surface 131. If a direct blowing method is adopted, after the gas is blown onto the inner surface 131, it is easy to diffuse and affect the temperature of the connecting rod 12, the straight cross bar 11 and even the outer surface 132, and the purpose of reducing the temperature difference of the rod will be affected.

[0047] The present invention also includes a manifold 30. In order to make the gas pressures blown out by multiple blowing mechanisms 20 consistent and reduce the number of external gas sources, the manifold 30 is set so that each blowing mechanism 20 is connected to the manifold 30 gas path. This can reduce other equipment used in conjunction with the device, reduce costs and ensure uniform air pressure.

[0048] Furthermore, in order to ensure that the air pressure of each nozzle 21 is equal, the blowing mechanism 20 also includes a gas diverter 22; the gas diverter 22 has multiple diverter ports and air inlets, and the multiple diverter ports are respectively connected to the air circuits of several nozzles 21, and the air inlet of the gas diverter 22 is connected to the air circuit of the manifold 30. In this example, one blowing mechanism 20 uses three nozzles 21, and the gas from the external gas source is distributed to four gas diverters 22 connected to its pipelines through the manifold 30. The gas diverter 22 sends gas with equal pressure to the three nozzles 21 respectively and blows it out through the air outlet 212 of the nozzle 21 and finally passes through the inner surface 131.

[0049] As a preferred embodiment, in order to improve the versatility of the present invention and adapt to stabilizer bars 10 of different structures, the blowing mechanism 20 also includes a positioning clamp 23 and an adjusting bracket 24 for clamping the nozzle 21; the positioning clamp 23 is movably arranged on the adjusting bracket 24 and can reciprocate between away from and close to the adjusting bracket 24. For stabilizer bars 10 of different structures, the number and position of the curved rod segments 13 on the stabilizer bar 10 will be different. Therefore, the adjusting bracket 24 and the positioning clamp 23 are provided to adjust the position of the nozzle 21 so that the nozzle 21 can always blow to the inner surface 131 of the curved rod segment 13.

[0050] Preferably, the adjustment bracket 24 includes a plurality of clamping blocks 241 and support rods 242, and the specific number of clamping blocks 241 and support rods 242 can be selected according to the specific structure of the stabilizer bar 10; each clamping block 241 has at least two clamping holes 2411, and the clamping holes 2411 are used to clamp the support rod 242 so that the clamping block 241 can be reciprocated along the extension direction of the support rod 242. In actual use, the clamping blocks 241 support each other by clamping the same support rod 242. The clamping blocks 241 can also reciprocate along the extension direction of the support rod 242 through the clamping holes 2411 to adjust the spacing between the clamping blocks 241, and can also be rotated around the axis of the support rod 242 through the clamping holes 2411 to adjust to the most suitable state. The positioning clamp 23 is extended with an adjusting rod 231, and the adjusting rod 231 can be inserted into any clamping hole 2411. After the positioning clamp 23 clamps the nozzle 21, the adjusting rod 231 can be adjusted arbitrarily in the clamping hole 2411 of the clamping block 241 to adjust the distance between the positioning clamp 23 and the clamping block 241. The adjusting rod 231 can also be located in the clamping hole 2411 and rotated around the axis of the adjusting rod 231 itself to meet the requirements of different nozzle 21 positions.

[0051] like Figure 2 and Figure 5As shown, in order to support the device structure and the stabilizer bar 10, the present invention further includes a bottom plate 40; the bottom plate 40 is used to mount and position the stabilizer bar 10 and fix the blowing mechanism 20. A plurality of support plates 41 are detachably provided on the bottom plate 40; the support plates 41 have brackets 411 whose shapes match the stabilizer bar 10, and the user can install the support plates 41 at different positions of the bottom plate 40 according to different stabilizer bar 10 structures.

[0052] The present invention also provides a method for heating and maintaining a constant temperature of a hollow stabilizer bar 10, comprising the above-mentioned hollow stabilizer bar heating and blowing device; the method for heating and maintaining a constant temperature of the hollow stabilizer bar 10 comprises:

[0053] The steps of fixing the stabilizer bar 10 are as follows: installing and fixing the stabilizer bar 10;

[0054] The stabilizer bar 10 that needs to be quenched is mounted and stabilized on the external tooling. Specifically, the stabilizer bar 10 is mounted on a support plate 41 installed on the bottom plate 40. In this example, there are four support plates 41, two of which are used to support the straight crossbars 11, and the other two are used to support the connecting rods 12 at both ends, so as to ensure that the stabilizer bar 10 is fixed during the processing and will not flip over.

[0055] Temperature gun setting steps: Set the temperature gun to monitor the surface temperature of the stabilizer bar 10;

[0056] At least two temperature measuring guns are arranged on opposite sides of the bending rod section 13, and the two temperature measuring guns are used to monitor the surface temperature of the inner surface 131 and the outer surface 132 respectively. Of course, in order to improve the processing quality of the stabilizer rod 10, more than two temperature measuring guns can be arranged at various parts of the stabilizer rod 10 to monitor the processing temperature of each part;

[0057] The blowing mechanism 20 is provided in the following steps: the blowing mechanism 20 is provided to cool the stabilizing bar 10;

[0058] The same number of blowing mechanisms 20 as the number of the bending rod segments 13 is provided, and the blowing mechanisms 20 adjust the positions of the positioning clamps 23 by adjusting the brackets 24, and the blowing mechanisms 20 are erected on one side of the inner surface 131 corresponding thereto, so that the blowing mechanisms 20 are connected to an external high-pressure gas source, so that the high-pressure gas sprayed by the nozzles 21 of the blowing mechanisms 20 can pass through the inner surface 131 corresponding thereto;

[0059] Temperature monitoring step: real-time monitoring of the temperature of the inner surface 131 and the outer surface 132 of the stabilizer bar 10 to obtain a temperature difference;

[0060] The stabilizer bar 10, specifically the hollow lateral stabilizer bar 10, is heated by means of resistance heating. During this process, the temperature of the inner surface 131 and the outer surface 132 of the stabilizer bar 10 is monitored in real time by a temperature measuring gun, and the temperature difference between the inner surface 131 and the outer surface 132 is calculated. Of course, if multiple temperature measuring guns are set to monitor different parts of the stabilizer bar 10, that is, the temperature difference between each part is monitored in real time, and the temperature difference between the inner surface 131 and other parts is monitored in particular;

[0061] Cooling step: when the temperature difference exceeds a preset value, the blowing mechanism 20 is controlled to operate to cool down the stabilizer bar 10;

[0062] When the temperature measuring gun detects that the temperature difference between the inner surface 131 and the outer surface 132 exceeds the preset value, the nozzle 21 of the blowing mechanism 20 is controlled to blow out high-pressure gas to cool the inner surface 131. Here, the temperature difference can be monitored by a PLC controller to control the blowing mechanism 20, or it can be controlled manually. During the heat treatment process, it is generally more appropriate to keep the temperature of the rod part within 50°. Of course, the temperature difference value can also be adjusted according to specific process requirements;

[0063] Reset step: when the temperature difference returns to within the preset value, the blowing mechanism 20 is controlled to stop;

[0064] When the temperature measuring gun detects that the temperature difference between the inner surface 131 and the outer surface 132 is within a preset value, the blowing mechanism 20 stops blowing out high-pressure gas. In this example, when the temperature of the inner surface 131 and the outer surface 132 is within ±50°, the blowing mechanism 20 stops.

[0065] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
