Description

Technical Field

[0001] This utility model relates to the technical field of copper ingot heating equipment, and in particular to a step-type copper ingot heating equipment. Background Technology

[0002] Due to their long length and heavy weight, rod-shaped copper ingots are generally transported and heated using step-type heating equipment.

[0003] For example, Chinese invention patent CN119617870A provides a walking beam furnace for bar stock, which can effectively achieve bar stock conveying and heating. However, due to the walking beam conveying principle, the copper ingot is lifted and lowered multiple times, which makes it easy for the copper ingot to deviate along the width of the furnace, or even collide with the furnace wall, affecting normal conveying and causing bar blockage.

[0004] Due to the high temperature inside the furnace, using complex positioning equipment will significantly increase the cost of using and maintaining the equipment. There is an urgent need for a new step-type copper ingot heating equipment to solve the problem of copper ingot deviation during transportation. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this invention is to propose a step-type copper ingot heating device that can correct the horizontal deviation of the copper ingot perpendicular to the step-feeding direction while the copper ingot is being conveyed normally, thus solving the problem of copper ingot deviation affecting normal conveying and causing rod blockage.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A stepping copper ingot heating device includes a furnace body, a heating unit, a control unit, and a stepping conveying unit. The heating unit is used to heat the inside of the furnace body, and the stepping conveying unit includes a balancing swing assembly, a driving assembly, and several push blocks.

[0008] The balancing swing assembly includes several swingable balancing swing brackets, which are disposed inside the furnace body. Each balancing swing bracket has a long strip-shaped placement part extending along the Y direction. The long strip-shaped placement part is used to hold copper ingots. The length of the long strip-shaped placement part is less than the length of the copper ingot to be held. The midpoint of the long strip-shaped placement part is the swing center. The balancing swing bracket swings around the X-axis at the swing center. The balancing swing bracket swings due to the weight distribution of the copper ingot.

[0009] The pushing block is located inside the furnace body. Several pushing blocks are spaced apart along the X direction. Several pushing blocks are respectively located on both sides of the balance swing assembly, and the pushing blocks on both sides are arranged opposite each other. The driving assembly is used to drive the pushing block to rise and fall in the Z direction, and to drive the pushing block to provide a driving force for the copper ingot to move in the Y direction.

[0010] Each of the two ends of the balance swing bracket is respectively equipped with a push block. Two push blocks located at the two ends of the same balance swing bracket are a push block pair. The lifting and lowering of the push blocks is used to drive the lifting and lowering of the copper ingot on the balance swing bracket. Under the drive of the drive assembly, the push block pair transports the copper ingot on the balance swing bracket to the elongated placement part of the next balance swing bracket. The control unit is used to control the drive assembly and the heating unit.

[0011] Preferably, the balancing swing assembly further includes a mounting shaft, the axis of which is arranged along the X direction, and the middle part of the balancing swing bracket is provided with a mounting through hole along the X direction. The balancing swing bracket is rotatably sleeved on the mounting shaft through the mounting through hole.

[0012] Preferably, the balancing swing assembly further includes several limiting blocks, which are disposed below both ends of the balancing swing bracket along the Y direction. The limiting blocks are used to limit the maximum value of the tilt angle α of the balancing swing bracket. The tilt angle α is the angle between the elongated placement part and the Y direction, and the maximum value of the tilt angle α is 1~3°.

[0013] Preferably, an elastic element is provided between the limiting block and the balancing swing bracket, the elastic element being used to keep the elongated placement portion parallel to the Y direction when the elongated placement portion does not support the copper ingot.

[0014] Preferably, the balancing swing assembly further includes several counterweights connected to the bottom of the balancing swing bracket.

[0015] Preferably, a bearing is provided between the mounting shaft and the balance swing bracket.

[0016] Preferably, a bushing is provided between two adjacent balance swing brackets, and the bushing is fitted onto the mounting shaft.

[0017] Preferably, the elongated placement portion is provided with a plurality of strip-shaped protrusions, the length direction of the strip-shaped protrusions is arranged through the Y direction, and the top surface of the strip-shaped protrusions is arc-shaped.

[0018] Preferably, the push block includes a connecting part, two rotating shafts, and two clamping blocks. The connecting part is connected to the output part of the drive assembly. The two rotating shafts are connected to the connecting part, and the axes of the rotating shafts are arranged along the Y direction. The two clamping blocks are respectively mounted on the connecting part in the X direction via the two rotating shafts, and the two clamping blocks can rotate around the axis of the rotating shaft on which they are mounted. Each clamping block includes a supporting part, a clamping part, and a limiting part. The supporting part and the clamping part of the same clamping block are located on both sides of the rotating shaft on which they are mounted. When the push block lifts the copper ingot, the supporting part is used to support the copper ingot, the clamping part is used to clamp the copper ingot, and the limiting part is used to limit the rotation angle of the push block.

[0019] Preferably, the surfaces of the supporting portion and the clamping portion are provided with anti-slip stripes.

[0020] The technical solution provided by this utility model can include the following beneficial effects:

[0021] 1. By employing a rotatable balancing swing bracket, when the balancing swing bracket supports a copper ingot, if the copper ingot deviates along the Y direction, causing one end of the copper ingot to extend excessively beyond the elongated placement section, the balancing swing bracket rotates, and the elongated placement section tilts downwards along the extended end of the copper ingot, causing the copper ingot on it to tilt downwards along with the elongated placement section. When the next pair of push blocks lift the copper ingot again, the lower end of the tilted copper ingot is first lifted by one of the push blocks. While one of the push blocks lifts the copper ingot upwards, it pushes the copper ingot towards the other end in the Y direction, thus correcting the deviation of the copper ingot along the Y direction. This solves the problem of the cumulative increase in the deviation of the copper ingot along the Y direction, which affects the normal conveying of the copper ingot and causes blockage. Furthermore, it eliminates the need for an additional correction drive device, performing deviation correction during the normal lifting and lowering of the push blocks, reducing equipment usage and maintenance costs, and solving the problem that conventional deviation correction devices require additional drivers, have complex structures, and high equipment costs.

[0022] 2. A balanced swing bracket is mounted via a mounting shaft. The mounting shaft and the balanced swing bracket form a lever structure with equal lengths at both ends. When a copper ingot is placed on the balanced swing bracket, if the copper ingot has a Y-direction offset, causing one end of the ingot to protrude a longer strip-shaped placement section, and since copper ingots are typically rod-shaped with a uniform cross-section, the longer end is heavier. Under the influence of gravity, the balanced swing bracket rotates, causing the long strip-shaped placement section to tilt downwards along the longer protruding end of the copper ingot. This simple lever structure allows the balanced swing bracket to rotate under the weight of the copper ingot, eliminating the need for an additional offset detection device and reducing equipment costs.

[0023] 3. The tilt angle 'a' of the balance swing bracket is limited by the limit block to avoid the problem that insufficient tilt angle 'a' leads to poor offset correction effect, while excessive tilt angle 'a' leads to over-correction of offset. Attached Figure Description

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] A stepping copper ingot heating device includes a furnace body 1, a heating unit 2, a control unit, and a stepping conveying unit. The heating unit 2 is used to heat the inside of the furnace body 1. The stepping conveying unit includes a balancing swing assembly, a driving assembly 31, and several push blocks 32.

[0038] The balancing swing assembly includes several swingable balancing swing brackets 33, which are disposed inside the furnace body 1. Each balancing swing bracket 33 has a long strip-shaped placement part 331 extending along the Y direction. The long strip-shaped placement part 331 is used to hold copper ingots. The length of the long strip-shaped placement part 331 is less than the length of the copper ingot to be held. The midpoint of the long strip-shaped placement part 331 is the swing center. The balancing swing bracket 33 swings around the X-axis at the swing center. The balancing swing bracket 33 swings due to the weight distribution of the copper ingot.

[0039] The push block 32 is located inside the furnace body 1. A plurality of push blocks 32 are arranged at intervals along the X direction. The plurality of push blocks 32 are respectively arranged on both sides of the balance swing assembly, and the push blocks 32 on both sides are arranged opposite each other. The drive assembly 31 is used to drive the push blocks 32 to rise and fall in the Z direction, and to drive the push blocks 32 to provide a driving force for the copper ingot to move in the Y direction.

[0040] Each of the two ends of the balance swing bracket 33 is respectively associated with a push block 32. Two push blocks 32 located at the two ends of the same balance swing bracket 33 form a push block pair. The lifting and lowering of the push block 32 is used to drive the lifting and lowering of the copper ingot on the balance swing bracket 33. Under the drive of the drive assembly 31, the push block pair transports the copper ingot on the balance swing bracket 33 to the elongated placement part 331 of the next balance swing bracket 33. The control unit is used to control the drive assembly 31 and the heating unit 2.

[0041] like Figure 1 and Figure 2 As shown, when the step-type copper ingot heating equipment is used for copper ingot conveying, the conveying direction of the copper ingot is along the X direction, and the length direction of the copper ingot is along the Y direction. After the copper ingot enters the furnace body 1, the first pair of push blocks 32 lifts the copper ingot and moves it forward along the X direction, then places the copper ingot on the first balanced swing bracket 33. Then the next pair of push blocks 32 lifts the copper ingot again and moves it forward along the X direction, placing the copper ingot on the next balanced swing bracket 33. This cycle is repeated to achieve step-type conveying of the copper ingot. Figure 6 As shown, the offset of copper ingot 4 along the Y direction is mainly due to the slight time difference between the lifting and lowering of the two ends of the copper ingot along its length. During the repeated lifting and lowering, the slight offset is gradually amplified.

[0042] like Figure 7As shown, by employing a rotatable balancing swing bracket 33, when the balancing swing bracket 33 supports the copper ingot, if the copper ingot is offset along the Y direction, causing one end of the copper ingot to extend too far beyond the elongated placement part 331, the balancing swing bracket 33 rotates, and the elongated placement part 331 tilts downward along the longer end of the copper ingot, causing the copper ingot on it to tilt downward along with the elongated placement part 331. When the next pair of push blocks 32 lifts the copper ingot again, the tilted lower end of the copper ingot is first lifted by one of the push blocks 32. While one of the push blocks 32 lifts the copper ingot upward, it pushes the copper ingot towards the other end in the Y direction, thus correcting the offset of the copper ingot along the Y direction. This solves the problem of the cumulative increase in the offset of the copper ingot along the Y direction, which affects the normal conveying of the copper ingot and causes blockage. Furthermore, no additional correction drive device is required. Offset correction is performed during the normal lifting and lowering process of the push blocks 32, reducing the cost of equipment use and maintenance. This solves the problem that conventional offset correction devices must add a driver, resulting in a complex structure and high equipment cost.

[0043] like Figure 3 As shown, in a specific embodiment, the X and Y directions are perpendicular to each other along the horizontal plane, and the Z direction is vertical. The driving assembly 31 is driven by a plurality of first hydraulic cylinders 311 arranged along the X direction and a plurality of second hydraulic cylinders 312 arranged along the Y direction. The first hydraulic cylinders 311 are fixed to an external fixing structure, and the second hydraulic cylinders 312 are connected to the output of the first hydraulic cylinders 311. The output of the second hydraulic cylinders 312 is connected to the push block 32. The first hydraulic cylinders 311 and the second hydraulic cylinders 312 are controlled by a control unit (not shown in the figure) to realize the cyclic movement of the push block 32 along a rectangular trajectory.

[0044] Preferably, the balancing swing assembly further includes a mounting shaft 34, the axis of which is arranged along the X direction, and the center of the balancing swing bracket 33 is provided with a mounting through hole along the X direction. The balancing swing bracket 33 is rotatably sleeved on the mounting shaft 34 through the mounting through hole.

[0045] In a specific embodiment, the mounting shaft is fixed by several brackets, and the balance swing bracket 33 is mounted on the mounting shaft 34. The mounting shaft 34 and the balance swing bracket 33 form a lever structure with equal lengths at both ends. When the copper ingot is placed on the balance swing bracket 33, if the copper ingot has a Y-direction offset, causing one end of the copper ingot to extend longer than the elongated placement part 331, and since the copper ingots are all rods with a uniform cross-section, the longer end is heavier, the balance swing bracket 33 rotates under the action of gravity, causing the elongated placement part 331 to tilt downwards along the longer end of the copper ingot. Through a simple lever structure, the balance swing bracket 33 rotates under the action of the copper ingot's gravity, eliminating the need for an additional offset detection device and reducing equipment costs.

[0046] Preferably, the balancing swing assembly further includes a plurality of limiting blocks 35, which are disposed below both ends of the balancing swing bracket 33 along the Y direction. The limiting blocks 35 are used to limit the maximum value of the tilt angle α of the balancing swing bracket 33. The tilt angle α is the angle between the elongated placement part 331 and the Y direction, and the maximum value of the tilt angle α is 1~3°.

[0047] The tilt angle α of the balance swing bracket 33 is limited by the limit block 35 to avoid the problem that insufficient tilt angle α leads to poor offset correction effect, and excessive tilt angle α leads to excessive offset correction.

[0048] Preferably, an elastic element is provided between the limiting block 35 and the balancing swing bracket 33. The elastic element is used to keep the elongated placement part 331 parallel to the Y direction when the elongated placement part 331 does not support the copper ingot.

[0049] In one embodiment, the elastic element (not shown in the figure) is a spring. One end of the spring is connected to the limiting block 35, and the other end of the spring is connected to the bottom of the balance swing bracket 33. After the copper ingot leaves the elongated placement part 331, the elasticity of the spring allows the balance swing bracket 33 to return to parallel with the Y direction, preventing the copper ingot from being driven by the tilted balance swing bracket 33 when it is put down, which would cause the copper ingot to deflect more along the Y direction.

[0050] Preferably, the balancing swing assembly further includes a plurality of counterweights 36, which are connected to the bottom of the balancing swing bracket 33.

[0051] In another embodiment, the counterweight 36 acts as a weight, allowing the balance swing bracket 33 to return to parallelism with the Y direction, thus avoiding the problem of high cost of using elastic elements in high-temperature environments.

[0052] Preferably, a bearing is provided between the mounting shaft 34 and the balance swing bracket 33.

[0053] Using bearings (not shown in the figure) reduces the rotational resistance of the balance swing bracket 33, preventing the copper ingot's gravity from failing to drive the balance swing bracket 33 to rotate due to the small offset.

[0054] Preferably, a bushing 37 is provided between two adjacent balance swing brackets 33, and the bushing is sleeved on the mounting shaft 34.

[0055] The bushing 37 separates the two adjacent balance swing brackets 33, preventing the sides of the two adjacent balance swing brackets 33 from contacting each other and avoiding contact friction that could affect the rotation of the balance swing brackets 33.

[0056] Preferably, the elongated placement part 331 is provided with a plurality of strip-shaped protrusions, the length direction of the strip-shaped protrusions is arranged through the Y direction, and the top surface of the strip-shaped protrusions is arc-shaped.

[0057] The use of arc-shaped, strip-like protrusions (not shown in the figure) reduces the friction between the copper ingot and the balancing swing bracket 33 along the Y direction, preventing the inability to effectively correct the offset due to excessive friction. When the copper ingot is in the shape of a round bar, it also prevents the copper ingot from rolling back and forth along the X direction, thus avoiding further increases in offset caused by rolling back and forth.

[0058] Preferred, such as Figure 5 As shown, the push block 32 includes a connecting part 321, two rotating shafts 322, and two clamping blocks 323. The connecting part 321 is connected to the output part of the drive assembly 31. The two rotating shafts 322 are connected to the connecting part 321, and the axes of the rotating shafts 322 are arranged along the Y direction. The two clamping blocks 323 are respectively mounted on the connecting part 321 in the X direction via the two rotating shafts 322, and the two clamping blocks 323 can respectively surround the rotating shafts 322 on which they are mounted. The axis of 22 rotates. The clamping block 323 includes a supporting part 3231, a clamping part 3232, and a limiting part 3233. The supporting part 3231 and the clamping part 3232 of the same clamping block 323 are located on both sides of the rotating shaft 322 on which it is mounted. When the pushing block 32 lifts the copper ingot, the supporting part 3231 is used to support the copper ingot, the clamping part 3232 is used to clamp the copper ingot, and the limiting part 3233 is used to limit the rotation angle of the pushing block 32.

[0059] When the push block 32 lifts the copper ingot, the support part 3231 supports the copper ingot. Under the action of gravity, the copper ingot presses down on the support part 3231. The support part 3231 drives the clamping block 323 to rotate. The rotation of the clamping block 323 drives the clamping part 3232 to clamp the copper ingot, so as to avoid the push block 32 and the copper ingot from sliding and thus failing to effectively correct the offset.

[0060] Preferably, the surfaces of the supporting portion 3231 and the clamping portion 3232 are provided with anti-slip stripes.

[0061] The friction between the push block 32 and the copper ingot is further increased by the anti-slip stripes (not shown in the figure), ensuring the effective realization of the offset correction.
