Description

Technical Field

[0001] The present disclosure relates to the technical field of rolling equipment, and more particularly, to a rolling equipment for copper-aluminum alloy flat bars. Background Art

[0002] During the transfer of copper-aluminum alloy flat bar coils, they are usually placed vertically (the axis of the reel of the copper-aluminum alloy flat bar coil is set vertically).

[0003] In the related art, during the rolling process of copper-aluminum alloy flat bars, it is necessary to directly change the vertically placed copper-aluminum alloy flat bar coil to a horizontal placement, and then install it on the discharging module.

In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0047] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the icon to another component, these terms are used in this specification only for convenience, for example, according to the directions of the examples described in the accompanying drawings. It can be understood that if the device of the icon is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.

[0048] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and refer to the possible existence of additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", etc. are used only as labels and do not limit the quantity of their objects nor their order.

[0049] In this application, unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integral; it can be directly connected or indirectly connected through an intermediate medium.

[0050] The material of the cladding layer in the copper-aluminum alloy flat bar is copper (T2 copper, which is a grade of pure copper in industry, indicating that its purity level is above 99.90% and belongs to cathode remelted copper), and the core is aluminum alloy (Al1070 aluminum (commercial pure aluminum) or 8030 aluminum alloy). The density of this copper-aluminum alloy flat bar is 4250 kg / m³, the elastic modulus is 81 GPa, the yield strength is 250 Mpa, the tensile strength is 350 Mpa, the Poisson's ratio is 0.32, and it has strong plasticity.

[0051] The copper-aluminum alloy flat bar has two sizes. One is 40 mm (width) × 32 mm (thickness) with an edge fillet of 4 mm, and the other is 30 mm (width) × 30 mm (thickness) with an edge fillet of 4 mm. The copper-aluminum alloy flat bars are usually set in rolls to form copper-aluminum alloy flat bar coils (wherein, the copper-aluminum alloy flat bar coils include a reel and the copper-aluminum alloy flat bars coiled around the reel). The length of the copper-aluminum alloy flat bars on the copper-aluminum alloy flat bar coils is up to 90 m, and the weight of the copper-aluminum alloy flat bar coils is up to 490 Kg, and handling equipment is required for handling and transferring.

[0052] During the transfer of the copper-aluminum alloy flat bar coils, they need to be placed vertically (the axis of the reel of the copper-aluminum alloy flat bar coils is set vertically). In the related art, during the rolling process of the copper-aluminum alloy flat bars, the vertically placed copper-aluminum alloy flat bar coils need to be directly changed to a horizontal placement and then installed on the discharging module, and the rolling of the copper-aluminum alloy flat bars is carried out by means of horizontal feeding and horizontal discharging. After the rolling is completed, the horizontally placed copper-aluminum alloy flat bar coils after rolling are removed from the receiving module and then changed to a vertical setting for transportation. This process requires multiple changes in the orientation of the copper-aluminum alloy flat bar coils, with many processes consuming a lot of manpower and high costs.

[0053] To solve the above problems, the present disclosure provides a rolling device for copper-aluminum alloy flat bars, see Figure 1, including a discharging module 100, a continuous rolling mill unit 200, and a material receiving module (not shown in the figure) arranged in sequence. Among them, a vertically arranged coiled copper-aluminum alloy flat bar to be rolled is provided on the discharging module 100. The inlet of the continuous rolling mill unit 200 is arranged corresponding to the outlet of the discharging module 100, and the inlet of the material receiving module is arranged corresponding to the outlet of the continuous rolling mill unit 200. A vertically arranged coiled rolled aluminum alloy flat bar is provided on the material receiving module.

[0054] In an embodiment of the present disclosure, refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 , the discharging module 100 includes a material feeding unit 110, a rotating and lifting unit 120, a loop unit 130, a pinch and straightening unit 140, a shearing unit 150, and a control unit. Among them, the control unit is electrically connected to the material feeding unit 110, the rotating and lifting unit 120, the loop unit 130, the pinch and straightening unit 140, and the shearing unit 150, and is used to control the operation of the material feeding unit 110, the rotating and lifting unit 120, the loop unit 130, the pinch and straightening unit 140, and the shearing unit 150.

[0055] Among them, the material feeding unit 110 is used to vertically arrange the coiled copper-aluminum alloy flat bar and is configured to rotate and change materials. The rotating and lifting unit 120 is configured to drive the coiled copper-aluminum alloy flat bar on the material feeding unit 110 to lift and rotate for discharging. The loop unit 130 is configured to monitor the discharging speed of the coiled copper-aluminum alloy flat bar (i.e., the rotating speed of the rotating and lifting unit 120), so that the discharging speed of the coiled copper-aluminum alloy flat bar can match the rolling speed of the continuous rolling mill unit 200. The pinch and straightening unit 140 is configured to straighten the copper-aluminum alloy flat bar, and the shearing unit 150 is configured to shear the irregular part at the head of the coiled copper-aluminum alloy flat bar (the part that is still irregular after being straightened by the pinch and straightening unit 140).

[0056] In an embodiment of the present disclosure, the coiled copper-aluminum alloy flat bar can be vertically arranged on the material feeding unit 110.

[0057] In an embodiment of the present disclosure, refer to Figure 8 , the material feeding unit 110 includes a first fixing frame 1, a first driving assembly 2, a rotating frame 3, and at least two support trays (not shown in the figure).

[0058] In one example, the material feeding unit 110 includes two support trays. In another example, the material feeding unit 110 includes three support trays. In another example, the material feeding unit 110 includes four support trays. Of course, in other embodiments, the material feeding unit 110 can also include more than four support trays.

[0059] In the present disclosure, the feeding unit 110 includes three supporting trays (the supporting trays are not shown in the figure) as an example for introduction.

[0060] In this embodiment, the first driving assembly 2 is installed on the first fixing frame 1, and the output end of the first driving assembly 2 is connected to the rotating frame 3.

[0061] In one example, the first driving assembly 2 includes a first driving motor and a speed reducer. The first driving motor and the speed reducer are arranged on the first fixing frame. The output end of the first driving motor is connected to the input end of the speed reducer, and the output end of the speed reducer is connected to the rotating frame. Among them, the output shaft of the speed reducer is arranged vertically, and the input shaft of the speed reducer is arranged horizontally. Of course, in other examples, the first driving assembly 2 can also adopt other structures not shown.

[0062] In this embodiment, there are three rotating disks 4 eccentrically arranged on the rotating frame 3 (the eccentricity in the present disclosure means that the axis of the rotating frame 3 is parallel to the axis of the rotating disk 4 and not on the same straight line). The three rotating disks 4 are evenly arranged (in other words, the angle between any two adjacent rotating disks 4 is 120 degrees). A limiting ring 5 is arranged on each rotating disk 4, and each supporting tray is arranged in the corresponding limiting ring 5. The supporting tray is used to place the copper-aluminum alloy flat bar coil.

[0063] In this embodiment, the limiting ring 5 has an inclined surface on the side facing the center of the rotating disk 4. The limiting ring 5 has a first annular structure and a second annular structure. The first annular structure and the second annular structure are arranged on the rotating disk 4. The second annular structure is arranged on the side of the first annular structure close to the center of the rotating disk 4. The cross section of the first annular structure can be rectangular, and the cross section of the second annular structure can be trapezoidal or triangular. The inclined surface of the second annular structure faces the center position, so that there is a space with a wider upper part and a narrower lower part in the middle of the limiting ring 5. Among them, the inclined surface can play a guiding role, so that the copper-aluminum alloy flat bar coil can be located at the specified position, avoiding placement deviation, and can reduce the difficulty of placement (compared with the limiting ring without an inclined surface, in the scheme where the copper-aluminum alloy flat bar coil needs to be aligned to be put in, the scheme of setting an inclined surface in the present disclosure can improve the picking and placing speed of the copper-aluminum alloy flat bar coil).

[0064] In one example, the limiting ring 5 can be a continuous structure. In other examples, the limiting ring 5 can be formed by a plurality of spaced limiting blocks. In this way, by adjusting the positions of the respective limiting blocks, the limiting ring 5 can be made suitable for supporting trays of different sizes.

[0065] In the present disclosure, refer to Figure 1 And Figure 8, it is defined that the discharging module 100 has a discharging position and two storage positions. The copper-aluminum alloy flat bar coil on the supporting tray at the discharging position rotates for discharging, and the copper-aluminum alloy flat bar coil on the supporting tray at the storage position is stored and waits for discharging. When the rolling of the copper-aluminum alloy flat bar coil at the discharging position is completed, the first driving component 2 drives the supporting tray to rotate, so that the next supporting tray rotates from the storage position to the discharging position for rolling the copper-aluminum alloy flat bar coil on the next supporting tray. The previous supporting tray located at the discharging position rotates to the storage position after rotation, and a copper-aluminum alloy flat bar coil is re-placed for storage and placement of the copper-aluminum alloy flat bar coil, so as to perform the next round of discharging and rolling. In this way, the loading time can be greatly reduced and the rolling efficiency can be improved.

[0066] In the present disclosure, a multi-station feeding unit 110 (multiple supporting trays) is adopted. The copper-aluminum alloy flat bar coil at the discharging position is discharged and rolled, and the copper-aluminum alloy flat bar coil at the storage position waits for discharging, greatly shortening the loading time of the copper-aluminum alloy flat bar coil and improving the rolling efficiency.

[0067] In an embodiment of the present disclosure, the middle of the rotating disk 4 has a first through hole exposing a partial area of the supporting tray. The rotating and lifting unit 120 is located at the loading position and below the rotating disk 4. The output end of the rotating and lifting unit 120 can pass through the first through hole and be clamped with the supporting tray, driving the supporting tray to move upward to disengage from the limiting ring 5 and rotate for discharging. After the discharging is completed, the rotating and lifting unit 120 drives the supporting tray to move downward and be located within the limiting ring 5.

[0068] In an embodiment of the present disclosure, refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 , the rotating and lifting unit 120 includes a rotating and lifting mechanism 21 and a clamping tray 22. The power output end of the rotating and lifting mechanism 21 is connected to the clamping tray 22. The rotating and lifting mechanism 21 is configured to drive the clamping tray 22 to lift and rotate. In the present disclosure, no limitation is imposed on the rotating and lifting mechanism 21 as long as it can meet the response function. In one example, the rotating and lifting mechanism 21 may include a rotating component and a lifting component. Among them, the lifting component may be connected to the output end of the rotating component, and the lifting component is connected to the clamping tray 22 to realize the superposition of the rotating and lifting functions. In one example, the rotating component may adopt a motor and a reduction box in cooperation.

[0069] In this example, the clamping tray 22 has a central positioning bump 23 and an eccentric limiting bump 24. The support tray is provided with a central positioning hole that cooperates with the central positioning bump 23, and an eccentric limiting hole that cooperates with the eccentric limiting bump 24. The central positioning hole and the eccentric limiting hole are exposed by the first through hole. During use, the rotary lifting mechanism 21 drives the clamping tray 22 to move upward, so that the central positioning bump 23 of the clamping tray 22 is clamped in the central positioning hole, and the eccentric limiting bump 24 is clamped in the eccentric limiting hole. Then, under the drive of the rotary lifting mechanism 21, the support tray disengages from the limiting ring 5, and then the rotary lifting mechanism 21 drives the support tray to rotate for discharging.

[0070] In one example, the central positioning bump 23 has a structure that is narrower at the top and wider at the bottom. That is, the central positioning bump 23 has an inclined surface. In the present disclosure, the set inclined surface can be used to finely adjust the position of the support tray for placing the copper-aluminum alloy flat bar coil so that the support tray is clamped with the clamping tray 22.

[0071] In the present disclosure, through the cooperation of the feeding unit 110 and the rotary lifting unit 120, the discharging module 100 realizes vertical discharging and directly transfers the copper-aluminum alloy flat bar coil (before or after rolling) without the need to additionally change the orientation of the copper-aluminum alloy flat bar coil, saving manpower and material resources, avoiding scratches during the transfer process, and moreover, adopting the multi-station storage method can improve the rolling efficiency.

[0072] In one embodiment of the present disclosure, the present disclosure adopts an auxiliary rotary motion method, which can further ensure the rotary stability of the rotary disk 4 and the copper-aluminum alloy flat bar coil located on the rotary disk 4 and reduce power consumption. In one example, referring to Figure 8 , the first fixing frame 1 has an annular slide rail. One end of the rotary disk 4 is connected to the rotary frame 3, and the other end is provided with a rotating wheel 6. The rotating wheel 6 is arranged in the annular slide rail and can roll along the annular slide rail. In this way, when the rotary disk 4 rotates under the drive of the first driving component 2, the rotating wheel 6 rolls synchronously in the annular slide rail, which can not only reduce the power consumption of the first driving component 2 and reduce costs, but also further ensure the rotary stability of the rotary disk 4 and the copper-aluminum alloy flat bar coil located on the rotary disk 4.

[0073] In one embodiment of the present disclosure, referring to Figure 1 , the loop unit 130 is arranged on one side of the discharging position, that is, the loop unit 130 is arranged on the discharging side of the support tray located at the discharging position. In this way, during discharging, the copper-aluminum alloy flat bar can pass through the loop unit 130 and enter the pinch straightening unit 140.

[0074] In the present disclosure, the loop unit 130 is used to monitor whether the rotation speed of the rotary lifting unit 120 matches the rolling speed of the continuous rolling mill 200.

[0075] In an embodiment of the present disclosure, refer to Figure 2 and Figure 3 With Figure 4 , the loop unit 130 has a material passing channel, which can be opened before rolling to allow the copper-aluminum alloy flat bar to enter and closed during rolling to monitor whether the rotation speed of the rotary lifting unit 120 matches the rolling speed of the tandem rolling mill 200.

[0076] In an embodiment of the present disclosure, the loop unit 130 has three groups of proximity switch groups at the material passing channel. The three groups of proximity switch groups are arranged in sequence along the first direction of the material passing channel. Each group of proximity switch groups includes at least one proximity switch 15, and the respective proximity switches 15 are arranged in sequence along the first direction of the material passing channel. Thus, at the material passing channel, a plurality of proximity switches 15 are arranged along its first direction, and the proximity switches 15 are configured to detect the position of the copper-aluminum alloy flat bar in the material passing channel.

[0077] In one example, the respective proximity switches 15 are arranged close to the rotary lifting unit 120. In this way, the state of the copper-aluminum alloy flat bar at the feeding port of the loop unit 130 can be monitored, and the monitoring result is more accurate.

[0078] In an embodiment of the present disclosure, refer to Figure 1 and Figure 9 , the included angle Q between the feeding port of the material passing channel and the arrangement direction of each rolling mill in the tandem rolling mill 200 is 50°-70°; in this way, when the rotation speed of the rotary lifting unit 120 and the rolling speed are coordinated, the copper-aluminum alloy flat bar can have three different positions, making the monitoring result more accurate. Specifically, in the present disclosure, the working principle of the loop unit 130 is as follows: when the rolling speed of the tandem rolling mill 200 matches the rotation speed of the rotary lifting unit 120 (i.e., the rolling speed matches the discharging speed), the copper-aluminum alloy flat bar is in the second position (middle part) in the material passing channel. At this time, the second group of proximity switch groups detects the copper-aluminum alloy flat bar, indicating that the rotation speed of the rotary lifting unit 120 does not need to be adjusted. When the rolling speed of the tandem rolling mill 200 is greater than the rotation speed of the rotary lifting unit 120 (i.e., the rolling speed is greater than the discharging speed), the copper-aluminum alloy flat bar is in a pulling state and is in the third position (one end) in the material passing channel. At this time, the third group of proximity switch groups detects the copper-aluminum alloy flat bar, indicating that the rotation speed of the rotary lifting unit 120 needs to be increased. When the rolling speed of the tandem rolling mill 200 is less than the rotation speed of the rotary lifting unit 120 (i.e., the rolling speed is less than the discharging speed), the copper-aluminum alloy flat bar will arch and is in the first position (the other end) in the material passing channel. At this time, the first group of proximity switch groups detects the copper-aluminum alloy flat bar, indicating that the rotation speed of the rotary lifting unit 120 needs to be decreased.

[0079] In one example, refer toFigure 9 The included angle Q between the feed inlet of the material passing channel and the arrangement direction of each rolling mill in the continuous rolling mill unit 200 is 50°, 55°, 60°, 65°, 70°, etc. In the present disclosure, the arrangement direction of each rolling mill is the moving direction of the copper-aluminum alloy flat bar within the continuous rolling mill unit 200.

[0080] In one example, referring to Figure 2 、 Figure 3 and Figure 4 , the loop unit 130 may include a second fixing frame 11, a second driving assembly 12, a movable structure 13, a U-shaped fixing structure 14, and three groups of proximity switch groups;

[0081] Among them, the second fixing frame 11 has a first plate surface and a second plate surface; the U-shaped fixing structure 14 is arranged on the second plate surface of the second fixing frame 11, and the movable structure 13 is located on the opening side of the U-shaped fixing structure 14, forming a material passing channel with the U-shaped fixing structure 14. One end of the movable structure 13 is hinged to the first plate surface of the second fixing frame 11, and the other end is vacant. The fixed end of the second driving assembly 12 is hinged to the first plate surface of the second fixing frame 11, and the movable end is hinged to the movable structure 13.

[0082] The second driving assembly 12 is configured to drive the movable structure 13 to move so as to open or close the material passing channel. In other words, under the drive of the second driving assembly 12, the movable structure 13 has a first position and a second position.
