Technical Field

[0001] This utility model relates to the field of cable tray processing technology, specifically to a continuous shearing device for cable tray processing. Background Technology

[0002] Cable trays are widely used in power, communication, and control systems to support and protect cables and pipelines, helping to achieve neat cable layout and effective management. Shearing machines play an important role in cable tray processing, cutting metal sheets with blades to cut the metal strip raw material to the dimensions required for processing cable tray components.

[0003] The raw material metal strip used in existing cable tray processing often warps during subsequent use because the curling stress after rolling and coiling is not released, seriously affecting the overall quality and stability of the cable tray. Therefore, a continuous shearing device for cable tray processing is proposed to provide a continuous shearing mechanism for metal strip raw materials. This improves the efficiency of cable tray processing and performs stress-relieving shaping treatment on the metal strip before shearing, resulting in better strip shape and improving the quality of the cable tray made from the sheared metal strip.

[0017] Specifically, the shearing portion includes:

[0018] Support base, mounted on the base;

[0019] The tool holder is mounted on the support base;

[0020] The cutter is connected to the support base;

[0021] The hydraulic cylinder is connected to the support base;

[0022] Connecting arm, which connects to the cutter and hydraulic cylinder.

[0027] Specifically, a gear is provided at one end of both the first and second material rollers, and the gear of the first material roller meshes with the gear of the second material roller.

[0028] By adopting the above technical solution, the gear can help the first and second rollers rotate in opposite directions.

[0029] The beneficial effects of this utility model are as follows: The assembly consisting of a conveying section and a shearing section provides a continuous shearing mechanism for metal strip raw materials in cable tray processing, which can effectively improve the efficiency of cable tray processing.

[0035] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0036] To improve, such as Figure 1-3 As shown, the continuous shearing device for cable tray processing according to this utility model includes:

[0037] Base 1;

[0038] Conveying unit 2 is mounted on base 1;

[0039] The shearing part 3 is disposed on the base 1.

[0040] In use, the conveying unit 2 and the shearing unit 3 provide a continuous shearing mechanism for the metal strip raw material in the cable tray processing, which can effectively improve the efficiency of cable tray processing and perform stress-relieving shaping treatment on the metal strip before shearing, which helps to cut the metal strip into a better shape and improve the quality of the cable tray made from the sheared metal strip.

[0041] For example, to transport raw materials, such as Figure 1 , 2 As shown, the present invention also includes, the conveying unit 2 comprising:

[0042] Material bed 201 is mounted on base 1;

[0043] The first material roller 202 is connected to the material bed 201;

[0044] The second material roller 203 is connected to the material bed 201;

[0045] The third material roller 205 is connected to the material bed 201;

[0046] The fourth material roller 206 is connected to the material bed 201.

[0047] The second material roller 203 is located on top of the first material roller 202. The first material roller 202 and the second material roller 203 are disposed at the discharge end of the material bed 201. The fourth material roller 206 is located on top of the third material roller 205. At least one set of the third material roller 205 and the fourth material roller 206 is disposed at the feed end of the material bed 201.

[0048] The third material roller 205 is an electromagnetic heating roller. The metal strip entering the material bed 201 is heated by the third material roller 205 to release the stress generated by the long-term winding of the metal strip in advance, which helps to cut the metal strip into a better shape and improves the quality of the cut metal strip as a cable tray.

[0049] For example, such as Figure 1 , 3 As shown, this utility model also includes, the shearing part 3 includes:

[0050] Support base 301 is mounted on base 1;

[0051] Tool holder 302 is mounted on support base 301;

[0052] The cutter 303 is connected to the support base 301;

[0053] Hydraulic cylinder 304 is connected to support base 301;

[0054] The connecting arm 305 is connected to the cutter 303 and the hydraulic cylinder 304.

[0055] In use, the connecting arm 305 is pushed out by the hydraulic cylinder 304, which in turn pushes down the cutter 303, thereby shearing the metal strip passing between the cutter holder 302 and the cutter 303.

[0056] For example, such as Figure 3As shown, the present invention also includes a sleeve of the hydraulic cylinder 304 connected to the top of the support base 301 via a rotating shaft, a connecting arm 305 fixedly installed on the output end of the hydraulic cylinder 304, a end of the connecting arm 305 away from the hydraulic cylinder 304 rotatably connected to the cutter 303 via a rotating shaft, and a end of the cutter 303 away from the connecting arm 305 rotatably connected to the support base 301 via a rotating shaft.

[0057] For example, such as Figure 2 As shown, the present invention also includes a stepper motor 207 at the bottom of the material bed 201, and pulleys 208 are installed on both the drive end of the stepper motor 207 and the rotating shaft of the first material roller 202. The pulleys 208 of the stepper motor 207 and the pulleys 208 of the first material roller 202 are connected by a transmission belt.

[0058] To reduce stress, for example, such as Figure 2 As shown, the present invention also includes a gear 204 provided at one end of the first material roller 202 and the second material roller 203, wherein the gear 204 of the first material roller 202 meshes with the gear 204 of the second material roller 203.

[0059] In use, this invention is assembled at the discharge end of an uncoiler. The uncoiler uncoils the metal strip of the cable tray processing material. The uncoiled metal then passes between the third roller 205 and the fourth roller 206, and then between the first roller 202 and the second roller 203. The top heights of the third roller 205 and the first roller 202 are the same as the top height of the cutter holder 302. During conveying, the stepper motor 207 drives the corresponding pulley 208 to rotate, causing the first roller 202 to rotate. Based on the meshing of the gear 204, the first roller 202 and the second roller 203 rotate in opposite directions, continuously conveying the metal strip between the cutter holder 302 and the cutter 303. The hydraulic cylinder 304 pushes out the connecting arm 305, causing the connecting arm 305 to push down the cutter 303, thus completing the continuous shearing process of the metal strip passing between the cutter holder 302 and the cutter 303.

[0060] During the process of the metal strip entering the conveyor section 2, the metal strip entering the material bed 201 is heated by the third material roller 205. The rolling of the third material roller 205 and the fourth material roller 206 allows the metal strip to be rolled and shaped while the stress of heating is released. This allows the stress generated by the long-term winding of the metal strip to be released in advance before shearing, resulting in better flatness of the cut metal strip and improving the quality of the cut metal strip as a cable tray.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
