[0018] This utility model has at least the following beneficial effects: The copper-aluminum busbar forming and copper-coating mold provided by this utility model sets a slider and a forming block on the lower mold plate, and a punch is set on the upper mold base. The sliding direction of the slider intersects with the moving direction of the punch. When the punch moves down and drives the slider to move, the forming block extrudes and coats the copper at the material end of the workpiece. This is low-cost and high-efficiency. It solves the problems of environmental pollution and relatively weak bonding between the electroplated layer and the aluminum core caused by the existing copper plating process, which are prone to peeling and flaking. In particular, the intersecting sliding direction of the slider and the moving direction of the punch effectively avoids the situation where the punch is deformed due to the repeated high-frequency punching operation when the traditional mold is vertically punched on the workpiece, which affects the stamping accuracy of the workpiece. This application can extend the service life of the mold.
[0019] Furthermore, after the punch completes the stamping, the second spring in the reset assembly drives the slider to move away from the forming block. With the help of the snap-fit block in the reset assembly, the slider is buffered, avoiding direct rigid contact between the slider and the lower die, thus extending the service life of the die. Since the side face of the snap-fit block facing the slider and the side face of the punch facing the snap-fit block are both perpendicular planes, the side face of the punch is perpendicular to the slider. This effectively prevents the punch from tilting laterally due to the stamping, ensuring the punch's extrusion force on the slider. This further ensures the stamping force of the forming block on the workpiece and guarantees the stamping quality.
[0020] In addition, by setting limit posts on the lower template, the stripper plate will first abut against the limit posts when the mold is closed, applying extrusion pressure to the limit posts and adhering to the upper surface of the shaped workpiece without applying external force. The symmetrically arranged limit posts, lower template and stripper plate surround the shaped workpiece at multiple points, thereby constraining the shaped workpiece and ensuring that the shaped workpiece is placed flat.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0029] Example 1
[0030] like Figure 1 and Figure 4 As shown, the present invention provides a copper-aluminum busbar shaping and copper-cladding mold, comprising:
[0031] The upper mold assembly includes an upper mold base 1 and a punch 4, wherein the punch 4 is fixedly clamped on the upper mold base 1;
[0032] The lower mold assembly includes a lower mold base 11, a lower template 10, a shaping block 13, a slider 14, and a reset assembly. The lower template 10 is fixedly mounted on the lower mold base 11. The shaping block 13 is slidably connected to the lower template 10, and a shaping opening 131 is provided on one side of the shaping block 13. The side of the shaping block 13 away from the shaping opening 131 is fixedly connected to the slider 14. The reset assembly is mounted on the lower template 10, and the output end of the reset assembly is drively connected to the slider 14. The slider 14 is slidably connected to the lower template 10. The punch 4 abuts against the slider 14, wherein the moving direction of the punch 4 intersects the sliding direction of the slider 14.
[0033] In the above embodiment, the lower mold base 11 is fixed to the workbench of the machine tool by bolts. The workpiece 9 is a copper-clad aluminum strip, which is long and narrow. The workpiece 9 is clamped and positioned on the lower mold plate 10 by the positioning member 12, and the end of the workpiece 9 to be shaped is located in the shaping neck 131. The upper mold base 1 is installed at the lower end of the piston rod (not shown in the drawing) of the hydraulic cylinder of the machine tool. The hydraulic cylinder drives the upper mold base 1 to move up and down, thereby causing the upper mold base 1 to drive the punch 4 to move up and down. When the punch 4 moves down to the point where the punch 4 abuts against the slider 14, the slider 14 drives the shaping block 13 to move toward the workpiece 9, thereby forcibly squeezing the end of the workpiece 9 located in the shaping neck 131, thus completing the wrapping work. In this case, along the sliding direction of the slider 14 and along the direction of the shaping block 13 adjacent to the slider 14, that is... Figure 4 As shown in the left-to-right direction, the size of the forming and shrinking nozzle 131 gradually decreases. As the forming block 13 moves toward the forming workpiece 9, the forming and shrinking nozzle 131 gradually shrinks and squeezes the material at the wrapping end of the forming workpiece 9 to ensure the quality of the copper wrapping. When the punch 4 moves upward, under the transmission of the reset component, the slider 14 drives the forming block 13 to move away from the forming workpiece 9 to the initial position, completing the demolding of the forming workpiece 9. The copper wall thickness after extrusion wrapping is not less than 0.05-2mm, which is low in cost and high in efficiency.
[0034] Furthermore, the moving direction of punch 4 intersects the sliding direction of slider 14, so as to... Figure 4 Taking the orientation shown as an example, the movement direction of the punch 4 is vertical, and the sliding direction of the slider 14 is horizontal. This effectively avoids the situation where the punch 4 is deformed due to the repeated high-frequency punching operation of the punch 4 when the traditional mold is directly applied to the workpiece in vertical punching, which affects the stamping accuracy of the workpiece. This application can extend the service life of the mold.
[0035] It should be noted that the positioning element 12 is used to fix and clamp the workpiece 9 on the lower template 10. For example, the positioning element 12 is a clamping telescopic element, which includes a clamping telescopic cylinder and a clamping element. The clamping telescopic cylinder drives the clamping element to abut and clamp the workpiece 9. Multiple clamping elements are provided, and multiple clamping elements are symmetrically arranged on the lower template 10 to achieve symmetrical clamping constraint on the workpiece 9, ensuring that the workpiece 9 is centered and that its shaping end is directly opposite the shaping neck 131.
[0036] Continue reading Figure 4 The punch 4 has a pressing protrusion 4a, and the slider 14 is provided with a pressing wedge surface 14a. The pressing protrusion 4a of the punch 4 abuts against the pressing wedge surface 14a, so that when the punch 4 moves vertically downward, it causes the slider 14 to drive the shaping block 13 to move horizontally. In other embodiments, the punch 4 has a pressing wedge surface 14a, and the slider 14 has a pressing protrusion 4a.
[0037] For example, see [link to relevant documentation]. Figure 4 and Figure 5 The reset assembly includes a reset screw 16, a second spring 18, and a locking block 15. The slider 14 is slidably connected to the lower template 10 through a displacement groove 101 formed on the lower template 10, and the lower template 10 has a locking groove 102 formed on it. The locking block 15 is installed in the lower template 10 through the locking groove 102. The slider 14 is located between the shaping block 13 and the locking block 15. The inner end of the reset screw 16 passes through the lower template 10 and the locking block 15 in sequence, and the reset screw 16 is slidably connected to the lower template 10 and the locking block 15 respectively. The inner end of the reset screw 16 is threadedly connected to the slider 14, and the outer end of the reset screw 16 is sleeved with the second spring 18.
[0038] In the above embodiment, the snap-fit block 15 is snapped into the lower template 10 via the snap-fit groove 102 and fixedly installed on the lower template 10 by bolts. At this time, the slider 14 is in the initial position, as shown below. Figure 4 and Figure 5 As shown, the slider 14 abuts against the locking block 15. When the slider 14 moves the shaping block 13 to the left under the pressure of the punch 4, the reset screw 16 compresses the second spring 18. When the punch 4 moves upward and disengages from the slider 14, the slider 14, under the elastic force of the second spring 18 (i.e., the reset spring), moves towards the locking block 15 to its initial position via the reset screw 16, thereby achieving the reset of the slider 14. Furthermore, the locking block 15 is provided on the side of the slider 14 away from the shaping block 13 to facilitate the reset of the slider 14. The inertial force generated during the movement process is buffered to avoid direct rigid contact between the slider 14 and the lower template 10, thus extending the service life of the mold. In addition, since the end face of the locking block 15 facing the slider 14 and the end face of the punch 4 facing the locking block 15 are both perpendicular planes, when the punch 4 squeezes the slider 14 for transmission, it effectively avoids the punch 4 from lateral tilting due to punching, ensuring the squeezing force of the punch 4 on the slider 14, thereby further ensuring the punching force of the forming block 13 on the forming workpiece 9 and ensuring the stamping quality.
[0039] For example, see [link to relevant documentation]. Figure 1 and Figure 2 The upper die holder 1 is provided with an upper clamping plate 3 on the side facing the lower die holder 11. The connection end of the punch 4 and the upper die holder 1 passes through the upper clamping plate 3 and is fixedly connected to the upper clamping plate 3. With the rigid support and positioning effect of the upper clamping plate 3 on the punch 4, the displacement deviation of the punch 4 due to high-speed reciprocating stamping motion and huge impact force at the moment of stamping is effectively avoided, thus ensuring the stamping accuracy of the punch 4.
[0040] Among them, such as Figure 1 and Figure 2As shown, an upper pad 2 is fixedly connected between the upper die base 1 and the upper clamping plate 3 to buffer the punch 4 and prevent the punch 4 from damaging or deforming the upper die base 1 during the punching operation.
[0041] For example, see [link to relevant documentation]. Figure 1 and Figure 2 The upper mold assembly also includes a stripper plate 6, a backing plate 5, a height equalizing sleeve 17, and a first spring 7. The stripper plate 6 is located between the upper clamping plate 3 and the lower template 10, and the stripper plate 6 is connected to the upper mold base 1 through the height equalizing sleeve 17. The backing plate 5 is fixedly connected to the side of the stripper plate 6 facing the upper clamping plate 3 by bolts. One end of the first spring 7 is fixedly connected to the backing plate 5, and the other end of the first spring 7 is fixedly connected to the upper clamping plate 3. The stripper plate 6 and the backing plate 5 are respectively provided with punch holes 41, and the positions of the punch holes 41 correspond to the positions of the punches 4.
[0042] When the upper die holder 1 drives the punch 4 to press down through the upper clamping plate 3, the stripper plate 6 first abuts against the lower die assembly, allowing the punch 4 to pass through the punch hole 41 and extrude force on the slider 14. At this time, the first spring 7 is compressed and deformed. When the punching ends and the punch 4 moves upward, the stripper plate 6 still abuts against the lower die assembly under the elastic force of the first spring 7, which helps the punch 4 to disengage from the slider 14. As the punch 4 continues to move upward, due to the equal height constraint of the equal height sleeve 17 on the upper die holder 1 and the stripper plate 6, the punch 4 is completely moved to the position above the stripper plate 6. The stripper plate 6 moves upward synchronously with the upper die holder 1 through the equal height sleeve 17. At this time, the distance between the upper clamping plate 3 and the stripper plate 6 remains fixed.
[0043] For example, see [link to relevant documentation]. Figure 1 and Figure 2 Multiple guide posts 8 are fixedly connected to the upper clamping plate 3. Guide holes 82 are respectively provided on the stripper plate 6 and the backing plate 5. The guide posts 8 slide in contact with the stripper plate 6 and the backing plate 5 through the guide holes 82. This helps to ensure the accuracy of the movement trajectory of the upper mold base 1 as it continues to move downwards, after the stripper plate 6 abuts against the lower mold assembly, thanks to the guiding constraint of the guide posts 8 and the guide holes 82. Furthermore, as... Figure 1 As shown, a clearance hole 81 is provided on the lower template 10. The clearance hole 81 is correspondingly set with the guide hole 82, so that after the guide end of the guide post 8 passes through the stripper plate 6, it is located in the clearance hole 81 and will not be interfered with by the lower template 10.
[0044] Example 2
[0045] Example 2 is based on Example 1, with the following further improvements: (See attached document for further details.) Figure 1Multiple limiting posts 19 are fixedly installed on the lower template 10 by bolts. The height of the upper end face of the limiting post 19 is consistent with the height of the upper surface of the workpiece 9. The limiting posts 19 limit the height of the workpiece 9 to meet the size requirements of the workpiece 9. Thus, when the stripper plate 6 moves down to abut the limiting post 19, the lower end face of the stripper plate 6 only touches the workpiece 9 and does not apply rigid extrusion force to it. Thus, the symmetrically arranged limiting posts 19, lower template 10 and stripper plate 6 surround the workpiece 9 at multiple points, thereby constraining the workpiece 9 and ensuring that the workpiece 9 is placed flat.
[0046] like Figure 6 As shown, the stripper plate 6 has a clearance groove 61 on the side facing the lower template 10. The clearance groove 61 is correspondingly set with the shaping block 13. Since the upper end face of the shaping block 13 is higher than the upper end face of the workpiece 9, and the stripper plate 6 moves down to fit the workpiece 9, by opening the clearance groove 61 on the stripper plate 6, when the stripper plate 6 moves down to abut against the limiting post 19, the upper end of the shaping block 13 is located in the clearance groove 61, so that the shaping block 13 will not be interfered with by the stripper plate 6 during the shaping and pressing process of the workpiece 9.
[0047] It should be noted that, in use, this copper-aluminum strip forming and copper-coating mold requires selecting a suitable forming block 13 according to the cross-sectional dimensions of the workpiece 9 and fixing it to the slider 14 with bolts. The workpiece 9 is then fixed to the lower template 10 by the positioning element 12. Under the drive of the hydraulic cylinder, the upper mold base 1 moves the punch 4 downward through the upper clamping plate 3. The stripper plate 6 first abuts against the limiting post 19, and the first spring 7 is compressed. At this time, the punch 4 passes through the punch hole 41, causing the extrusion protrusion 4a of the punch 4 to extrude the transmission slider. The extrusion wedge 14a of the 14 causes the slider 14 to move the shaping block 13 toward the shaping workpiece 9, thereby extruding and wrapping the material at the wrapping end of the shaping workpiece 9 through the shaping neck 131. This is low-efficiency and high-performance. The moving direction of the punch 4 intersects with the sliding direction of the slider 14, which effectively avoids the situation where the punch 4 is deformed due to repeated high-frequency punching operations when the traditional mold is vertically punched onto the workpiece, thus affecting the stamping accuracy of the workpiece. This application can extend the service life of the mold.
[0048] After the copper plating operation is completed, the punch 4 moves upward and disengages from the slider 14. Under the reset action of the second spring 18, the slider 14 drives the shaping block 13 to move towards the snap-fit block 15 to the initial position, thereby resetting the shaping block 13.
[0049] Furthermore, during the stamping process, by setting a limiting post 19 on the lower template 10, the height of the upper end face of the limiting post 19 is consistent with the height of the upper surface of the workpiece 9. The limiting post 19 restricts the height of the workpiece 9 to meet the size requirements of the workpiece 9. Thus, when the stripper plate 6 moves down to abut the limiting post 19, the lower end face of the stripper plate 6 only touches the workpiece 9 and does not apply a rigid extrusion force to it. Thus, by symmetrically arranged limiting posts 19, lower template 10 and stripper plate 6 surround the workpiece 9 at multiple points, the workpiece 9 is constrained and the workpiece 9 is kept flat.
[0050] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
