Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper sheet and strip processing technology, and in particular to an extrusion device for processing copper sheet and strip. Background Technology
[0002] Copper sheet and strip are important materials widely used in electronic equipment, aerospace, construction, and other fields, possessing excellent electrical and thermal conductivity. The production of copper sheet and strip often involves numerous processing steps, one of which is extrusion, which refers to pressing copper rods into sheet shape using extrusion equipment to meet required dimensions.
[0003] The working principle of extrusion equipment is to extrude a copper rod through two extrusion rollers. However, current extrusion equipment often cannot adjust the gap between the extrusion rollers according to the required copper strip size, and the post-extrusion processing is also lacking, resulting in problems such as uneven surface and dimensional deviations in the extruded copper strip. Utility Model Content
[0004] The purpose of this invention is to overcome the defects of the existing technology and provide an extrusion device for processing copper sheet and strip.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] An extrusion apparatus for processing copper sheet and strip includes an extrusion table. The extrusion table has a concave structure and is divided in the middle by a partition. The front half is an extrusion groove, and the rear half is a cooling groove. A first lower pressure roller, a second lower pressure roller, and a third lower pressure roller of the same size are sequentially arranged in the extrusion groove along the traveling direction of the copper sheet and strip. The first lower pressure roller, the second lower pressure roller, and the third lower pressure roller are arranged parallel to each other on the same horizontal plane. A first upper pressure roller is arranged above the first lower pressure roller. A second upper pressure roller is arranged above the second lower pressure roller. The first, second, and third lower pressure rollers, as well as the first and second upper pressure rollers, are rotatably fixed to the side walls at both ends of the extrusion groove via rotating shafts. A support is provided above the third lower pressure roller in the extrusion groove, and two telescopic cylinders are symmetrically fixed on the support. A third upper pressure roller is positioned above the third lower pressure roller. Both ends of the third upper pressure roller are rotatably fixed to the side walls of an inverted concave support plate via rotating shafts. Each of the two telescopic cylinders is equipped with a telescopic rod, and the lower ends of the two telescopic rods are symmetrically fixed to both ends of the upper surface of the support plate.
[0007] Furthermore, the gap between the first lower pressure roller and the first upper pressure roller is greater than the gap between the second lower pressure roller and the second upper pressure roller.
[0008] Furthermore, the cooling tank is provided with coolant; the coolant is an emulsion.
[0009] Furthermore, a winding structure for pulling the copper strip forward is provided behind the extrusion table; the winding structure includes a winding bracket and a winding roller mounted on the winding bracket; a motor is also provided on the winding bracket; the rotating end of the motor passes through the winding bracket and connects to the winding roller.
[0010] Furthermore, a rectangular opening is provided on the rear wall of the cooling tank for the copper strip to pass through after cooling; the rectangular opening is a smooth opening.
[0011] Furthermore, the two telescopic cylinders are cylinders that are synchronously controlled for lifting using the same controller.
[0012] Furthermore, the first lower pressure roller, the second lower pressure roller, the third lower pressure roller, the first upper pressure roller, the second upper pressure roller, and the third upper pressure roller are all pressure rollers made of high-strength stainless steel with smooth surfaces.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] This invention utilizes multi-stage extrusion to continuously extrude copper strips multiple times, resulting in extruded copper strips that better meet requirements and achieve excellent extrusion effects. The multi-stage, progressive extrusion process also avoids surface unevenness issues caused by single-stage extrusion. Furthermore, the upper and lower pressure rollers of the final extrusion stage can be adjusted to accommodate the gap between them, better meeting the extrusion requirements of copper strips of different sizes, and can be freely adjusted as needed. The extruded copper strips are then cooled rapidly by the coolant in the subsequent cooling tank, which improves their strength properties. Attached Figure Description

[0026] Example
[0027] like Figures 1-3 As shown, an extrusion device for processing copper strip includes an extrusion table 1. The extrusion table 1 has a concave structure and is divided in the middle by a partition. The front half is an extrusion groove 2, and the rear half is a cooling groove 3. The cooling groove 3 is filled with a coolant. The coolant is an emulsion, which can rapidly cool the copper strip after extrusion. The emulsion can ensure that it will not cause corrosion or oxidation to the copper strip itself and can improve the strength performance of the copper strip. The extrusion groove 2 is arranged sequentially along the traveling direction of the copper strip with a first lower pressure roller 4, a second lower pressure roller 5, and a third lower pressure roller 6 of the same size. Three lower pressure rollers 6; the first lower pressure roller 4, the second lower pressure roller 5, and the third lower pressure roller 6 are arranged parallel to each other on the same horizontal plane; a first upper pressure roller 7 is arranged above the first lower pressure roller 4; a second upper pressure roller 8 is arranged above the second lower pressure roller 5; both ends of the first lower pressure roller 4, the second lower pressure roller 5, the third lower pressure roller 6, the first upper pressure roller 7, and the second upper pressure roller 8 are rotatably fixed to the side walls at both ends of the extrusion groove 2 via rotating shafts; the gap between the first lower pressure roller 4 and the first upper pressure roller 7 is greater than the gap between the second lower pressure roller 5 and the second upper pressure roller 8, and the copper rod material is first pressed onto the first lower pressure roller 4 and the first upper pressure roller 7. The copper strip is squeezed into a larger size between the first upper pressure roller 7, and then squeezed a second time between the second lower pressure roller 5 and the second upper pressure roller 8 to form a medium-sized copper strip. A support 9 is provided above the third lower pressure roller 6 in the extrusion groove 2, and two telescopic cylinders 12 are symmetrically fixed on the support 9. A third upper pressure roller 10 is provided above the third lower pressure roller 6. The medium-sized copper strip is then squeezed between the third lower pressure roller 6 and the third upper pressure roller 10 to form the final copper strip of the required size. This multi-stage continuous extrusion process ensures a more complete extrusion of the copper strip and a smoother surface. The third upper pressure roller 10 is rotatably fixed at both ends to the side wall of an inverted concave support plate 11 via a rotating shaft; both telescopic cylinders 12 are equipped with telescopic rods 13, and the lower ends of the two telescopic rods 13 are symmetrically fixed to both ends of the upper surface of the support plate 11. The operator can adjust the extension and retraction of the telescopic rods 13 by activating the telescopic cylinders 12, thereby adjusting the gap between the third upper pressure roller 10 and the third lower pressure roller 6 to meet the extrusion requirements of copper strips of different sizes; in order to achieve synchronous control and keep both sides synchronously flat, the two telescopic cylinders 12 are synchronously controlled by the same controller.
[0028] A winding structure for pulling copper strip forward is provided behind the extrusion table 1; the winding structure includes a winding bracket 14 and a winding roller 15 mounted on the winding bracket 14; a motor 16 is also provided on the winding bracket 14; the rotating end of the motor 16 passes through the winding bracket 14 and connects to the winding roller 15. When the motor 16 is started, it drives the winding roller 15 to rotate, and the copper strip will be wound onto the winding roller 15, thereby generating traction force, pulling the copper rod through the extrusion groove 2 and being extruded into copper strip.
[0029] The rear wall of the cooling tank 3 is provided with a rectangular opening 17 for the copper strip to pass through after cooling; the rectangular opening 17 is a smooth opening.
[0030] The first lower pressure roller 4, the second lower pressure roller 5, the third lower pressure roller 6, the first upper pressure roller 7, the second upper pressure roller 8, and the third upper pressure roller 10 are all made of high-strength stainless steel with smooth surfaces, which can prevent marks from being left on the surface of the copper strip and make the extruded copper strip of higher quality.
[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
