Description

Technical Field

[0001] The invention belongs to the field of copper tube production, and in particular relates to a device for manufacturing copper strips by using copper tubes. Background Art

[0002] Precision copper tubes are often used in refrigeration or heating pipes and can be used in different environments. They are especially widely used in the field of white appliances. For example, they are one of the best connecting pipes in the condenser of the air conditioner.

[0003] Precision copper tubes need to be rolled into large reels for easy storage and transportation, and they need to be tied with copper tape to prevent them from loosening. The reason for using copper tape is that the last process of copper tubes is annealing. Other materials will react with copper tubes at high temperatures and affect their quality.

[0004] Generally speaking, copper strips are made by pressing copper strips. For copper tube manufacturers, in order to simplify the process, they will directly press the copper tube to produce copper strips. However, the strips directly pressed from copper tubes are thicker and there is a risk of delamination.

[0005] Prior art Chinese patent CN03112864.5 discloses a method for manufacturing copper strip, wherein copper is cast into a hollow casting tube by a horizontal continuous casting method, and then the obtained hollow casting tube is peeled on the outer surface and rolled with a large reduction on a three-roll planetary rolling mill to form a copper tube, and then the rolled copper tube is cut longitudinally and gradually unfolded and flattened, and finally rolled to obtain a copper strip.

[0006] Although the copper strip production method described above can ensure quality, the complicated process affects production efficiency. Summary of the invention

[0007] In view of this, the present invention provides a device for manufacturing copper strips using copper tubes, which can manufacture copper strips quickly and easily.

[0008] In order to solve the above technical problems, the technical solution of the present invention is: a device for manufacturing copper strips using copper tubes, comprising a straightening mechanism for straightening the copper tubes, a rolling mechanism for pressing the copper tubes to be flat, a trimming mechanism for trimming, and a winding mechanism for winding the copper strips and the surplus materials, which are arranged in sequence;

[0009] The trimming mechanism includes a trimming roller pair, which includes a roller I and a roller II that are arranged in parallel and rotate relatively. The roller I is provided with an annular boss, and the roller II is provided with an annular groove that cooperates with the annular boss. The width of the annular boss is consistent with the width of the manufactured copper strip, and the width of the annular groove is greater than or equal to the width of the copper strip and less than the width of the copper tube after being pressed to a flat state.

[0010] As an improvement, the roller wheel 1 comprises a disc-shaped middle blade and disc-shaped side pads arranged at both ends of the middle blade; the middle blade and the side pads are arranged concentrically, and the diameter of the middle blade is larger than that of the side pads. An annular soft pad is inlaid on the end surface of the side pad close to the middle blade.

[0011] As an improvement, the roller II includes two disc-shaped side knives and a disc-shaped middle pad arranged between the two side knives; the side knives and the middle pad are arranged concentrically, and the diameter of the side knives is larger than that of the middle pad. Annular soft pads are inlaid on the two end surfaces of the middle pad.

[0012] As a preference, the roller I and roller II are arranged in the up and down directions, with the roller I located at the top and the roller II located at the bottom.

[0013] As an improvement, both ends of the roller I and roller II are connected to the bearing seats by bearings, the bearing seats at both ends of the roller I are floatingly set on the frame, and springs are arranged between the bearing seats at both ends of the roller I and the bearing seats at both ends of the roller II; a cross beam is arranged above the bearing seats at both ends of the roller I; and the adjusting bolt passes through the cross beam and rests on the bearing seats at both ends of the roller I.

[0014] Preferably, the straightening mechanism comprises two rows of straightening rollers arranged in parallel, the two rows of straightening rollers are arranged alternately at intervals, and the spacing between the two rows of straightening rollers is consistent with the diameter of the copper tube.

[0015] As an improvement, the rolling mechanism includes a rolling roller pair, and the rolling roller pair includes rollers I II and roller IV that are arranged in parallel and rotate relatively.

[0016] As an improvement, a bottom plate is arranged between the rolling mechanism and the trimming mechanism, and the height of the bottom plate is consistent with the upper tread of the roller II; it also includes a pressure plate arranged above the bottom plate, and the gap between the pressure plate and the bottom plate is consistent with the thickness of the copper tube after being pressed to a flat state.

[0017] As an improvement, the winding mechanism includes two winding wheels for winding up the copper strip and two winding wheels for winding up the remaining material.

[0018] As an improvement, the winding mechanism further comprises a stripping wedge block arranged in front of the winding wheel, and the stripping wedge block is in the shape of a wedge with a small front and a large rear.

[0019] The present invention is beneficial in that:

[0020] The copper strip manufacturing device with the above structure first uses the straightening mechanism to straighten the copper tube, and then uses the rolling mechanism to press the copper tube into a flat shape. Then the trimming mechanism is used to cut off the two sides of the flat copper tube, so that the upper and lower copper strips can be obtained. Figure 4As shown. An annular boss and an annular groove are respectively provided on roller I and roller II. Both edges of the annular boss and the edge of the annular groove are cutting edges, and the two sides of the flattened copper tube are cut off by shearing.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0034] like Figure 1 As shown, the present invention provides a device for manufacturing copper strips using copper tubes, comprising a straightening mechanism 1 for straightening the copper tube, a rolling mechanism 2 for pressing the copper tube to a flat state, a trimming mechanism 3 for trimming, and a winding mechanism 4 for winding the copper strips and the remaining materials, which are arranged in sequence;

[0035] The trimming mechanism 3 includes a trimming roller pair, which includes a roller I31 and a roller I I32 that are arranged in parallel and rotate relatively; the roller I31 is provided with an annular boss, and the roller I I32 is provided with an annular groove that cooperates with the annular boss; the width of the annular boss is consistent with the width of the manufactured copper strip, and the width of the annular groove is greater than or equal to the width of the copper strip and less than the width of the copper tube after being pressed to a flat state. It can be foreseen that the width of the annular groove is preferably consistent with the width of the annular boss, which is more conducive to the trimming operation.

[0036] The principle of the present invention is to first use the straightening mechanism 1 to straighten the copper tube, and then use the rolling mechanism 2 to press the copper tube into a flat shape. Then use the trimming mechanism 3 to cut off the two sides of the flat copper tube to obtain the upper and lower copper strips 100, and the residual material 200 after trimming can be further recycled. Figure 4 As shown. An annular boss and an annular groove are respectively provided on the rollers 131 and 132. Both edges of the annular boss and the edge of the annular groove are cutting edges, and the two sides of the flattened copper tube are cut off by shearing.

[0037] The present invention uses an existing copper tube to manufacture a copper strip, and only needs to straighten, roll and cut to make one copper tube into two copper strips, so that the copper strip not only meets the use requirements, but also has high manufacturing efficiency and simple process.

[0038] like Figure 2 As shown, more specifically, the roller 131 of the present invention includes a disc-shaped middle blade 311 and disc-shaped side pads 312 arranged at both ends of the middle blade 311; the middle blade 311 and the side pads 312 are arranged concentrically, and the diameter of the middle blade 311 is larger than the side pads 312. The edge of the middle blade 311 is a cutting edge, and the end surface of the side pad 312 close to the middle blade 311 is inlaid with an annular soft pad 313. An annular boss is formed by the middle blade 311 and the side pads 312.

[0039] The roller II includes two disc-shaped side cutters 321 and a disc-shaped middle pad 322 disposed between the two side cutters 321; the side cutters 321 and the middle pad 322 are disposed concentrically, and the diameter of the side cutters 321 is larger than that of the middle pad 322. The edges adjacent to the side cutters 321 and the middle pad 322 are cutting edges, and annular soft pads 323 are inlaid on the two end surfaces of the middle pad 322. An annular cutting groove is formed by the side cutters 321 and the middle pad 322.

[0040] In this embodiment, the annular soft pad 323 and the annular soft pad 313 are both made of polyurethane. The annular soft pad 313 on the side pad 312 is used to clamp the flattened copper tube to increase friction. The annular soft pad 323 on the middle pad 322 is used to support the copper strip after trimming to avoid damage to the copper strip. In addition, the annular soft pad 323 on the middle pad 322 can also provide a certain rebound space, which is conducive to shearing.

[0041] In this embodiment, the roller I31 and the roller I I32 are arranged in the up and down directions, and the roller I31 is located at the top and the roller I I32 is located at the bottom, and shearing is performed by pressing down on the annular boss.

[0042] In addition, both ends of the roller I31 and roller II32 are connected with bearing seats 314 and bearing seats 315 by bearings. The bearing seats 314 at both ends of the roller I31 are floatingly arranged on the frame 33, and springs 35 are arranged between the bearing seats 314 at both ends of the roller I31 and the bearing seats 324 at both ends of the roller II32; a crossbeam 34 is arranged above the bearing seats 314 at both ends of the roller I31; and an adjusting bolt 36 passes through the crossbeam 34 and abuts against the bearing seats 314 at both ends of the roller I31. The above arrangement can adjust the spacing between the roller I31 and the roller II32 to adapt to the production of copper strips of different models and thicknesses.

[0043] The straightening mechanism 1 in this embodiment includes two parallel rows of straightening rollers 11, which are staggered and arranged at intervals, and the spacing between the two rows of straightening rollers 11 is consistent with the diameter of the copper tube. In order to facilitate storage, the copper tube is rolled into a large coil, so the copper tube needs to be straightened through the gap between the two rows of straightening rollers 11.

[0044] In some other embodiments, the rolling mechanism includes a rolling roller pair, and the rolling roller pair includes rollers II I21 and IV22 that are arranged in parallel and rotate relatively. The rollers II I21 and IV22 are pressed into a flat shape, which is convenient for the trimming mechanism to cut the two sides.

[0045] In order to ensure that the copper tube is straight after being flattened, a bottom plate 51 is arranged between the rolling mechanism 2 and the trimming mechanism 3, and the height of the bottom plate 51 is consistent with the upper tread of the roller 1132; a pressing plate 52 is also arranged above the bottom plate 51, and the gap between the pressing plate 52 and the bottom plate 51 is consistent with the thickness of the copper tube after being pressed flat. The copper tube entering the trimming mechanism 3 is made straighter and is convenient for trimming.

[0046] In this embodiment, the winding mechanism 4 includes two winding wheels 41 for winding the copper strips and two winding wheels 42 for winding the remaining materials. In addition, the winding mechanism 4 also includes a stripping wedge 43 arranged in front of the winding wheels 41, and the stripping wedge 43 is a wedge-shaped one with a small front and a large rear. The stripping wedge 43 can strip the upper and lower copper strips apart to facilitate the winding.

[0047] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
