Description

Technical Field

[0001] This utility model relates to the field of auxiliary discharge correction, specifically an auxiliary discharge correction device for an extrusion spray quenching equipment. Background Technology

[0002] With the development of the automotive industry, aluminum extrusion is facing more challenging requirements. Many 6-series thin-walled profiles require T6, and the deformation is large after water quenching or vertical quenching. Spray quenching is usually used to improve this, but the product inevitably has large and uneven wall thickness. After passing through the spraying device, the product bends and twists, which adds to the difficulty of subsequent straightening. Based on the existing spraying device, the current workshop uses bottom vertical rollers to assist in straightening the material output, but the straightening effect is generally poor, and the lifespan is reduced after immersion in water.

[0003] Therefore, there is an urgent need to provide a new auxiliary discharge correction device for extrusion spray quenching equipment. Summary of the Invention

[0004] The purpose of this utility model is to provide an auxiliary discharge straightening device for extrusion spray quenching equipment, which can assist in straightening and discharge of profiles after they enter the spraying device, improve the situation of product twisting and poor straightness caused by uneven spray water flow, improve product yield, and reduce subsequent shaping processes.

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary discharge straightening device for an extrusion spray quenching equipment, including a base frame and two sets of straightening mechanisms arranged on the base frame. The two sets of straightening mechanisms are symmetrically arranged, and each set of straightening mechanisms includes a fixed frame and upper and lower clamping roller mechanisms and side clamping roller mechanisms installed on the fixed frame. The upper and lower clamping roller mechanisms include an upper clamping roller, a lower clamping roller, and a sliding base. The fixed frame is slidably mounted on the base frame through the sliding base and limited by several adjustment mechanisms. Each side of the fixed frame is provided with a pair of guide rails. A rotating shaft is inserted through the upper clamping roller. Both ends of the rotating shaft are equipped with sliding bearings. Each sliding bearing is slidably mounted on a pair of guide rails on the same side and its position is adjusted by the adjustment mechanism. A rotating shaft is inserted through the lower clamping roller. Both ends of the rotating shaft are equipped with square seat bearings. The square seat bearings are fixedly mounted on the sliding base.

[0006] The side clamping roller mechanism includes two symmetrically arranged side roller assemblies. Each side roller assembly includes a side roller, a side roller rocker arm, and a connecting seat. The side roller is arranged perpendicularly to the upper clamping roller and a rotating shaft three passes through it. The two ends of the rotating shaft three are fitted with the side roller rocker arms. Each side roller rocker arm is connected to the connecting seat through a connecting shaft. The two connecting seats are respectively fixed to the outside of the fixed frame and the sliding base. The outside of the upper side roller rocker arm is abutted and limited by the adjusting mechanism three.

[0007] Furthermore, the adjustment mechanism includes a lifting screw, a lifting sleeve, and a rotating handwheel. One end of the lifting screw passes through the fixed frame and extends into the bearing with a slider, where it is connected to the lifting sleeve. The other end is connected to the rotating handwheel. The lifting screw is threadedly connected to the fixed frame.

[0008] Furthermore, each of the second adjustment mechanisms includes an adjustment screw and an adjustment handle. One end of the adjustment screw passes through the inner side of the sliding base and abuts against or separates from the side wall of the base frame, while the other end is externally connected to the adjustment handle. The adjustment screw is threadedly connected to the sliding base.

[0009] Furthermore, a roller is installed on the inner bottom of the sliding base and is rotatably connected thereto. The lower end of the roller is located on the base frame and is rotatably connected thereto.

[0010] Furthermore, the adjustment mechanism includes an adjustment plate, a side roller screw, and a rotating handle. The adjustment plate is fixed on the fixed frame. One end of the side roller screw passes through the adjustment plate and abuts against the side roller rocker arm, while the other end is connected to the rotating handle. The side roller screw is threadedly connected to the adjustment plate.

[0011] Furthermore, an auxiliary support mechanism is provided between the two sets of correction mechanisms. The auxiliary support mechanism includes a fixed plate, a support wheel frame, and support wheels. The support wheel frame is mounted on the fixed plate, and there are two support wheels that are rotatably mounted on the support wheel frame. A driving component for driving its up and down movement is provided below the fixed plate.

[0012] Furthermore, the driving component is a driving cylinder or a jack.

[0013] Furthermore, the bottom of the base frame is provided with several foot cups.

[0014] The beneficial effects of this utility model are:

[0015] 1. The auxiliary discharge straightening device of the extrusion spray quenching equipment of this utility model can assist the profile in straightening and discharge after entering the spray device, improve the product twisting and straightness defects caused by uneven spray water flow, improve the product yield, and reduce subsequent shaping processes; specifically, according to the height of the profile, the distance between the upper and lower clamping rollers of the upper and lower clamping roller mechanism is adjusted by the first adjustment mechanism to flexibly pre-limit the profile in the upper and lower positions, and the distance between the two side rollers of the side clamping roller mechanism is adjusted by the third adjustment mechanism to limit the profile in the left and right positions, so that the profile is discharged straight.

[0016] 2. Through the design of the first adjustment mechanism, this utility model can adjust the position of the upper clamping roller and further adjust the distance between the upper and lower clamping rollers. This allows for flexible pre-limiting of the profile according to its height and is applicable to profiles of more sizes. Combined with the design of the third adjustment mechanism, it can be used to adjust the distance between the two side rollers.

Detailed Implementation

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In one specific embodiment of this utility model, such as Figure 1-6 As shown, an auxiliary discharge straightening device for an extrusion spray quenching equipment includes a base frame 1 and two sets of straightening mechanisms 2 arranged on the base frame 1. The two sets of straightening mechanisms 2 are symmetrically arranged, and each set of straightening mechanisms 2 includes a fixed frame 21 and an upper and lower clamping roller mechanism 22 and a side clamping roller mechanism 23 installed on the fixed frame 21. The upper and lower clamping roller mechanism 22 includes an upper clamping roller 221, a lower clamping roller 222 and a sliding base 223. The fixed frame 21 is slidably arranged on the base frame 1 through the sliding base 223 and is limited by several adjustment mechanisms 25. Specifically, in this embodiment, each adjustment mechanism 25 includes an adjustment screw 251 and an adjustment handle 252. One end of the adjustment screw 251 passes through the inner side of the sliding base 223 and abuts or separates from the side wall of the base frame 1, and the other end is externally connected to the adjustment handle 252. The adjustment screw 251 is threadedly connected to the sliding base 223.

[0028] The adjustment method of the second adjustment mechanism 25 is as follows: when it is necessary to adjust the position of the fixed frame 21 on the base frame 1, the adjustment handle 252 is rotated to drive the adjustment screw 251 to retract inside the sliding base 223, so that the end of the adjustment screw 251 is separated from the side wall of the base frame 1. In this way, the fixed frame 21 can be pushed to move under the action of external force. When it reaches the designated position, the adjustment handle 252 is rotated in the opposite direction to drive the adjustment screw 251 to rotate, so that the end of the adjustment screw 251 abuts against the side wall of the base frame 1, thereby limiting the current position of the fixed frame 21.

[0029] Specifically, a pair of guide rails 224 are provided on each side of the fixed frame 21, and a rotating shaft 225 passes through the upper clamping roller 221. Both ends of the rotating shaft 225 are equipped with sliding block bearings 226 (e.g., Figure 4 Each slider bearing 226 is slidably mounted on a pair of guide rails 224 on the same side and its position is adjusted by an adjustment mechanism 24. In this embodiment, the adjustment mechanism 24 includes a lifting screw 241, a lifting sleeve 242, and a rotating handwheel 243. One end of the lifting screw 241 passes through the fixed frame 21 and extends into the slider bearing 226 and is connected to the lifting sleeve 242. The other end is connected to the rotating handwheel 243. The lifting screw 241 is threadedly connected to the fixed frame 21. A rotating shaft 227 is inserted inside the lower clamping roller 222. Both ends of the rotating shaft 227 are equipped with square seat bearings 228, which are fixedly mounted on the sliding base 223.

[0030] The adjustment method of the adjustment mechanism 24 is as follows: by rotating the handwheel 243, the lifting screw 241 is driven to rise and fall, so that the sliding bearing 226 slides up and down on the guide rail 224, thereby adjusting the position of the upper clamping roller 221 and adjusting the distance between the upper clamping roller 221 and the lower clamping roller 222. This allows for flexible pre-limiting of the profile according to the profile height and can be used for profiles of more sizes.

[0031] Specifically, the side clamping roller mechanism 23 includes two symmetrically arranged side roller assemblies. Each side roller assembly includes a side roller 231, a side roller rocker arm 232, and a connecting seat 233. The side roller 231 is arranged perpendicularly to the upper clamping roller 221 and a rotating shaft 234 passes through it. The two ends of the rotating shaft 234 are fitted with side roller rocker arms 232. Each side roller rocker arm 232 is connected to a connecting seat 233 through a connecting shaft 235. The two connecting seats 233 are respectively fixed to the fixed frame 21 and the sliding frame 235. The outer side of the base 223, the outer side of the upper side roller rocker arm 232 is abutted and limited by the adjustment mechanism 26. In this embodiment, the adjustment mechanism 26 includes an adjustment plate 261, a side roller screw 262 and a rotating handle 263. The adjustment plate 261 is fixed on the fixed frame 21. One end of the side roller screw 262 passes through the adjustment plate 261 and abuts against the side roller rocker arm 232. The other end is connected to the rotating handle 263. The side roller screw 262 is threadedly connected to the adjustment plate 261.

[0032] The adjustment mechanism 26 is used to adjust the distance between the two side rollers 231. The specific adjustment method of the adjustment mechanism 26 is as follows: When it is necessary to increase the distance between the two side rollers 231, the side roller screw 262 is retracted inside the adjustment plate 261 by rotating the rotating handle 263. The distance between the two side rollers 231 can be increased by pushing the side roller rocker arm 232 outward. Then, the distance between the two side rollers 231 can be increased by rotating the rotating handle 263 in the opposite direction to extend the side roller screw 262 inside the adjustment plate 261 and abut against the side roller 231. Of course, to reduce the distance between the two side rollers 231, the side roller screw 262 is extended inside the adjustment plate 261 by rotating the rotating handle 263. The two side rollers 231 are pushed or driven closer under the action of external force to achieve the purpose of reducing the distance between the two side rollers 231.

[0033] Of course, in specific applications, different sizes of upper clamping roller 221, lower clamping roller, and side roller can be replaced to meet the needs of different profiles. Wear-resistant and high-temperature resistant materials, such as high-hardness alloys or ceramic coatings, can also be used to withstand high-temperature and high-precision straightening above 400℃.

[0034] Specifically, in this embodiment, a roller 27 is installed on the inner side of the bottom of the sliding base 223 and is rotatably connected thereto. The lower end of the roller 27 is located on the base frame 1 and is rotatably connected thereto. Through the design of this roller, the position of the sliding base 223 on the base frame 1 can be easily adjusted.

[0035] Specifically, in this embodiment, an auxiliary support mechanism 3 is provided between the two sets of correction mechanisms 2. The auxiliary support mechanism 3 includes a fixed plate 32, a support wheel frame 33, and support wheels 34. The support wheel frame 33 is mounted on the fixed plate 32, and there are two support wheels 34 rotatably mounted on the support wheel frame 33. A driving component is provided below the fixed plate to drive the support wheels 34 to move up and down. Through the design of the auxiliary support mechanism 3, the support wheels 34 can be driven to move up and down by the driving component, so that the support wheels 34 can fit against the product discharge, prevent the middle from being hollowed out, and play a certain supporting role.

[0036] Here, the driving component is a driving cylinder or a jack 31. In this embodiment, a jack 31 is selected, which can lift the support wheel 34 for lifting. Lifting by jacking is a widely used existing technology, so the working principle will not be described in detail here.

[0037] In this embodiment, the bottom of the base frame 1 is provided with several foot cups 4. The foot cups provide stable support and can also be adjusted in height. The height adjustment of the foot cups is an existing technology and will not be described in detail here.

[0038] The working principle of this utility model:

[0039] After the profile enters the spraying device, it is straightened and discharged with the assistance of the auxiliary discharge straightening device of this utility model. By adjusting the adjustment mechanism 24, the rotating handwheel 243 drives the lifting screw 241 to rise and fall, so that the sliding bearing 226 slides up and down on the guide rail 224 to adjust the position of the upper clamping roller 221. According to the height of the profile, the distance between the upper clamping roller 221 and the lower clamping roller 222 is controlled to pre-limit the profile in the vertical direction. Then, by adjusting the adjustment mechanism 26, the distance between the two side rollers 231 is adjusted to limit the profile in the left and right directions, so that the profile can be discharged straight and improve the product yield.

[0040] The auxiliary discharge straightening device of this utility model for extrusion spray quenching equipment can assist in straightening and discharging profiles after they enter the spraying device, improving the situation of product twisting and poor straightness caused by uneven spray water flow, increasing product yield, and reducing subsequent shaping processes. Specifically, according to the height of the profile, the distance between the upper and lower clamping rollers of the upper and lower clamping roller mechanism is adjusted by the first adjustment mechanism to flexibly pre-limit the profile in the upper and lower directions. Then, the distance between the two side rollers of the side clamping roller mechanism is adjusted by the third adjustment mechanism to limit the profile in the left and right directions, so that the profile is discharged straight.

[0041] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
