Description

Technical Field

[0001] This utility model relates to the field of copper rod production technology, and in particular to a copper bar straightening and angle-cutting machine. Background Technology

[0002] In the production of copper rods, chamfering is a crucial process to ensure smooth edges and reduce stress concentration in subsequent processing. Traditional chamfering typically employs direct scraping, where a hard tool is used to cut the copper rod's edges in a single pass to create the chamfer. However, this method has significant drawbacks: direct scraping involves a large contact area between the tool and the copper material, resulting in high cutting resistance and rapid tool wear or even chipping, increasing maintenance costs. Furthermore, the force of a single cut can cause uneven stress on the copper surface, leading to burrs or deformation at the chamfered edges, affecting product quality consistency. In addition, traditional equipment lacks an efficient debris removal mechanism, allowing residual copper shavings to adhere to the equipment's interior or the copper rod's surface, potentially causing secondary scratches or affecting subsequent processes.

[0029] Example

[0030] like Figures 1-2 As shown:

[0031] A copper strip straightening and corner trimming machine, including

[0032] A straightening box 1; the straightening box 1 is provided with a first straightening component 11 and a second straightening component 12; a straightening channel is formed between the first straightening component 11 and the second straightening component 12 for straightening copper strips;

[0033] Shaping device 2; the shaping device 2 is located on the rear side of the straightening box 1; the shaping device 2 is arranged in two sets in sequence, namely the first shaping mechanism 21 and the second shaping mechanism 22;

[0034] The shaping device 2 includes support frames 23 located on both sides; an adjustable assembly slot 24 is provided on the front side of the support frame 23; two sets of assembly slots 24 are provided and are configured in a V-shape; a second rotating shaft 25 is rotatably mounted on the bottom of the support frame 23 via a bearing seat; a first rotating wheel 26 is fixedly sleeved on the second rotating shaft 25; the assembly slot 24 adopts a V-shape structure in conjunction with a sliding movable plate 242, which supports angle adjustment and can be adapted to copper strips with different cross-sectional sizes;

[0035] A shaping channel is formed between the bottom of the two assembly slots 24 and the first rotating wheel 26;

[0036] A scoring blade 27 is installed on the assembly slot 24 of the first shaping mechanism 21; a chipping blade 28 is installed on the assembly slot 24 of the second shaping mechanism 22.

[0037] The first shaping mechanism 21 uses a scoring cutter 27 to pre-score teeth on the edge of the copper strip, and reduces the subsequent cutting resistance through stress guidance, making the chamfering process smoother;

[0038] The straightened copper strip enters the first shaping mechanism 21:

[0039] The first cylinder 2313 pushes the cylinder arm 2312, which drives the first rotating shaft 231 to rotate and adjusts the V-angle of the assembly groove 24 so that the scoring cutter body 27 presses the edge of the copper strip. When the copper strip moves, the scoring cutter body 27 continuously scores serrated marks on its edge to pre-crack the copper grain boundary and reduce the subsequent cutting resistance.

[0040] The second shaping mechanism 22, together with the adjustable ingot-removing cutter body 28, completes the chamfering and shaping. The two-stage processing makes the plastic deformation of the copper material controllable and improves the smoothness of the chamfered edge.

[0041] The copper bar enters the second shaping mechanism 22:

[0042] The ingot-removing blade 28 is installed on the T-slot plate 243 according to the preset chamfer angle and locked in position by bolts; the area with engraved marks on the edge of the copper strip undergoes directional plastic deformation under the scraping of the blade to form a smooth chamfer surface, thus controlling the chamfer width.

[0043] Back-blowing box 3; the back-blowing box 3 is located behind the ingot removal assembly; a back-blowing channel is provided at the center of the back-blowing box 3;

[0044] The straightening channel, shaping channel, and back-blowing channel are located on the same straight line. The shaping channel is coaxially connected with the straightening channel and back-blowing channel, enabling continuous straightening-chamfering-cleaning operations and improving the processing efficiency of a single production line.

[0045] The support frame 23 has a first rotating shaft 231 rotatably mounted on its top via a bearing seat; a fixing plate 232 is fixedly sleeved on the front end of the first rotating shaft 231; and the assembly groove 24 is located on the front side of the fixing plate 232.

[0049] The copper strip enters the straightening channel from the inlet guide 13. The second cylinder 112 drives the straightening arm 111 to press down, so that the upper roller 113 and the three sets of straightening rollers 121 work together to eliminate the original curvature of the copper strip through multi-stage reverse bending and output the copper strip.

[0050] The second straightening component 12 is located below the first straightening component 11; the second straightening component 12 is provided in three sets; the second straightening component 12 includes a straightening wheel 121 disposed on the front side of the straightening box 1 via a bearing seat.

[0051] The three sets of straightening rollers 121 are at the same horizontal level; the two sets of upper rollers 113 are at the same horizontal level; and an entrance guide 13 is provided on the front side of the straightening rollers 121.

[0054] The chamfered copper strip enters the back-blowing box 3: compressed air is introduced through the air inlet pipe 31, and the airflow flows in the opposite direction along the back-blowing channel to flush the surface of the copper strip and remove the attached debris; the debris falls into the discharge port 41 through the waste hopper 4 to achieve automatic recycling;

[0055] The straightening roller 32 supports the copper strip and maintains its transmission stability.

[0056] It also includes a frame 5; the straightening box 1, the shaping device 2 and the back-blowing box 3 are arranged sequentially on the frame 5.

[0057] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent.
