The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Figure 1-Figure 3 A pressing device for changing the size of a copper plate according to a preferred embodiment of the present invention is shown, which includes a cutting mechanism 1, a conveying mechanism 2, a forming seat 3 and a drawing mechanism arranged in sequence according to the working steps.

[0034] The cutting mechanism 1 includes a shearing and lifting drive mechanism 11 and a cutter 12 connected to the shearing and lifting drive mechanism 11. The cutter 12 is used to cut the end of the copper plate to reduce the width of the end of the copper plate, thereby facilitating the end of the copper plate to be inserted into the corresponding part of the forming seat 3.

[0035] The conveying mechanism 2 comprises a base 21, a first conveying roller 22, a second conveying roller 23, a first rotary drive mechanism, and a first lifting drive mechanism 24. The first conveying roller 22 is mounted on the base 21, and the second conveying roller 23 is mounted on the base 21, directly above or below the first conveying roller 22. This allows the first and second conveying rollers 22, 23 to jointly clamp and convey the copper plate. The first rotary drive mechanism is operatively connected to the second conveying roller 23, while the first lifting drive mechanism 24 is used to move the second conveying roller 23 closer to or further from the first conveying roller 22 to adjust the feed gap between the second and first conveying rollers 23. It should be noted that after passing through the notching mechanism 1, the copper plate is conveyed through the feed gap, which is slightly smaller than the thickness of the copper plate. This allows the first and second conveying rollers 22, 23 to work together to initially compress and flatten the copper plate. In particular, due to the relatively low hardness of the copper plate, it can be squeezed within the feed gap, causing some deformation.

[0036] The forming seat 3 is provided with a forming through hole 31 for the copper plate to pass through and press the copper plate. It is understood that the outer contour cross section of the copper plate passing through the forming through hole 31 will be shaped to be the same as the contour of the forming through hole 31, that is, the size of the copper plate is changed by forced pressing.

[0037] The pulling mechanism is used to clamp the copper plate so that the copper plate moves from one end of the forming through hole 31 to the other end of the forming through hole 31, that is, a strong pulling force is applied by the pulling mechanism so that the unwound copper plate is forcibly pulled through the forming through hole 31.

[0038] Obviously, the cutter 12 of the cutting mechanism 1 cuts the ends of the copper plate to reduce their width, making it easier for the ends to pass through the formed through-hole 31. The first conveyor roller 22 and the second conveyor roller 23 cooperate to convey the unwound copper plate, providing a power source for the copper plate to automatically unwind and automatically approach the formed through-hole 31. Furthermore, the first lifting drive mechanism 24 drives the second conveyor roller 23 to move closer to or away from the first conveyor roller 22, thereby adjusting the feeding gap. This makes the conveyor mechanism 2 suitable for copper plates of varying thicknesses and can initially squeeze the copper plate to change its thickness, further facilitating the passage of the ends of the copper plate through the formed through-hole 31. The pulling mechanism clamps and pulls the copper plate, providing the necessary power source for forcing the copper plate through the formed through-hole 31. Furthermore, under strong pressure, the copper plate is not only perfectly plasticized but also has a consistent cross-sectional area, thus ensuring the high quality of the resized copper plate.

[0039] To further press the copper plate after it has been rolled by the first and second conveyor rollers 22 and 23, thereby further flattening the copper plate and making it easier to pass through the forming through-hole 31, the pressing device for changing the size of the copper plate preferably also includes a pre-pressing mechanism 4. The pre-pressing mechanism 4 and the forming base 3 are arranged sequentially according to the process. The pre-pressing mechanism 4 includes a first squeezing roller 41, a second squeezing roller 42, and a second rotary drive mechanism. The first squeezing roller 41 is mounted on the base 21, and the second squeezing roller 42 is mounted on the base 21 and located directly above or below the first squeezing roller 41. To facilitate smoother rolling of the copper plate, the second rotary drive mechanism is drivably connected to the second squeezing roller 42. To ensure an adjustable squeezing gap between the first and second squeezing rollers 41 and 42 to accommodate copper plates of varying thicknesses, the pre-pressing mechanism 4 preferably also includes a second lifting drive mechanism 43. The second lifting drive mechanism 43 is used to drive the second squeezing roller 42 toward or away from the first squeezing roller 41 to adjust the squeezing gap between the second and first squeezing rollers 42 and 41.

[0040] Preferably, the first conveyor roller 22 is pivotally connected to the base 21. This arrangement allows the horizontal height of the first conveyor roller 22 to remain constant, thereby facilitating precise control of the lifting accuracy of the second conveyor roller 23. Preferably, the first squeeze roller 41 is pivotally connected to the base 21. Similarly, the horizontal height of the first squeeze roller 41 remains constant, thereby facilitating precise control of the lifting accuracy of the second squeeze roller 42.

[0041] In order to make the second conveying roller 23 rise and fall more smoothly, preferably, the base 21 is provided with a first guide rail 211 extending along the direction of gravity, the first guide rail 211 is movably connected to the first slider 212, the second conveying roller 23 is pivotally connected to the first slider 212 and supported by the first slider 212; the first lifting drive mechanism 24 is drive-connected to the first slider 212.

[0042] In order to facilitate the first rotation driving mechanism to drive the second conveying roller 23 , preferably, the first rotation driving mechanism is installed on the first slider 212 and supported by the first slider 212 .

[0043] Furthermore, the first lifting drive mechanism 24 has many structural forms, and in order to facilitate matching the movement mechanism of the first slider 212 and accurately adjust the feeding gap, preferably, the first lifting drive mechanism 24 includes a first motor 241 installed on the base 21, a first reducer 242 driven by the first motor 241, a first worm connected to the first reducer 242, and a first turbine connected to the first worm, and the first turbine is arranged on the first slider 212.

[0044] In order to make the second squeezing roller 42 rise and fall more smoothly, preferably, the base 21 is provided with a second guide rail 213 extending along the direction of gravity, the second guide rail 213 is movably connected to the second slider 214, the second squeezing roller 42 is pivotally connected to the second slider 214 and supported by the second slider 214; the second lifting drive mechanism 43 is drive-connected to the second slider 214.

[0045] In order to facilitate the second rotation driving mechanism to drive the second squeezing roller 42 , preferably, the second rotation driving mechanism is installed on the second slider 214 and supported by the second slider 214 .

[0046] Furthermore, the second lifting drive mechanism 43 has many structural forms, and in order to facilitate matching the movement mechanism of the second slider 214 and accurately adjust the extrusion gap, preferably, the second lifting drive mechanism 43 includes a second motor 431 installed on the base 21, a second reducer 432 driven by the second motor 431, a second worm connected to the second reducer 432, and a second turbine connected to the second worm, and the second turbine is arranged on the second slider 214.

[0047] Preferably, in order to facilitate the cutter 12 to complete the cutting at a suitable angle in one cut so that the end of the copper plate has a wedge-shaped structure, the extension direction of the cutter 12 is arranged at an acute angle to the feeding direction of the copper plate.

[0048] Since copper plates of different widths require different cutting widths, preferably, the base 21 is provided with a horizontal transverse guide rail 5, which is perpendicular to the feeding direction of the copper plate. The cutting mechanism 1 also includes a cutting seat 13, and the shear lifting drive mechanism 11 is mounted on the cutting seat 13. In this arrangement, by pushing the cutting seat 13 to adjust the position of the cutter 12 relative to the copper plate, the cutting amount of the copper plate can be changed, so as to cut out the necessary amount of waste.

[0049] Preferably, the drawing mechanism is a hydraulic drawing machine. It can be understood that the drawing mechanism can also be other equipment with a drawing force, such as a combination of an oil cylinder and a draw hook, etc.

[0050] In addition, the first rotary drive mechanism and the second rotary drive mechanism can both be selected from rotary motors, or a combination of a rotary motor and a conveyor belt, a rotary cylinder, a rotary oil cylinder, and the like.

[0051] The specific operation of the pressing device for changing the size of the copper plate is as follows: after releasing the end of the coiled copper plate, the end of the copper plate is placed in the cutting mechanism 1. The cutting seat 13 is then pushed to adjust the relative position of the cutter 12 and the copper plate to cut the necessary amount of scrap, thereby ensuring that the end of the copper plate is wide enough to pass through the forming hole 31. The second conveyor roller 23 is then driven down by the first lifting drive mechanism 24 to adjust the feeding gap between the second conveyor roller 23 and the first conveyor roller 22; and the second squeezing roller 42 is driven down by the second lifting drive mechanism 43 to adjust the squeezing gap between the second squeezing roller 42 and the first squeezing roller 41. The end of the copper plate is then placed in the feeding gap. Driven by the first rotary drive mechanism and the second rotary drive mechanism, the copper plate moves back and forth and is repeatedly flattened until the target thickness. Then, the worker passes the end of the copper plate through the forming hole and clamps the copper plate through the drawing mechanism. The copper plate is intermittently or continuously pulled under the strong pulling force of the drawing mechanism so that the copper plate is reshaped when passing through the forming through hole 31.

[0052] The above 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 replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
