[0002] The movable crossbeam, also known as the crossbeam grate, is one of the core components of a waste incinerator. Its manufacturing quality is directly related to its service life, combustion efficiency, and safety. The movable crossbeam is a linear component with an irregular cross-section, welded from several plates. In order to eliminate internal residual stress, straighten the shape of the rolled piece, and meet the assembly and welding accuracy requirements, it needs to be straightened. The existing method is to use the movable pressure head of the straightening machine on the operating platform to apply pressure to bend the steel component placed between two fixed support points to achieve the correction of the shape defects of the steel component. Processing according to this method cannot meet the multi-directional straightening requirements of components with irregular cross-sections, which will lead to reduced straightening effect; workers need to repeatedly adjust the placement of steel components during actual operation, which reduces work efficiency; if the steel components are not placed properly and the pressure applied is too high, it is easy to cause deformation of parts of the steel components during the straightening process, increasing the workload.

[0037] Figure 1This is a schematic structural diagram of the present invention. As shown in the figure, the straightening device for irregular section weldments in this embodiment includes a straightening auxiliary mechanism;

[0038] The irregular sectional weldment of this scheme is the workpiece to be straightened 001 shown in the figure, and the workpiece to be straightened 001 has a b-face and a b'-face parallel to each other, an a'-face perpendicular to the b-face and the b'-face, an a-face opposite to the a'-face and protruding upward at an obtuse angle, a special-shaped portion 1 protruding upward from the bending position of the a-face, the special-shaped portion 1 is arranged along the entire length of the workpiece to be straightened 001, and a rib 2 is arranged on the special-shaped portion 1 along the entire length of the workpiece to be straightened 001; the special-shaped portion 1 has a c-face at an obtuse angle to the a-face, and the rib 2 is arranged on the special-shaped portion 1 on the opposite side of the c-face.

[0039] The straightening auxiliary mechanism includes a base and a partition assembly, and the base has a receiving groove 6 with an open top. Specifically, the base includes a bottom plate 3, a left side plate 4 and a right side plate 5 arranged on both sides of the bottom plate 3. The left side plate 4 and the right side plate 5 are perpendicular to the bottom plate 3. The three are welded to each other to form a whole, forming a "U"-shaped receiving groove 6 structure with an open top. The bottom surface of the bottom plate 3 is parallel to the horizontal plane when in use, and the distance between the left side plate 4 and the right side plate 5 exceeds the width of the workpiece 001 to be straightened. The width of the bottom plate 3 exceeds the distance between the left side plate 4 and the right side plate 5, ensuring that the structure can be stably set in the specified position when in use, thereby improving the straightening quality of the workpiece 001 to be straightened. The designated position is generally the straightening platform 003 or the horizontal plane of the straightening equipment. The present solution also includes a straightening equipment, which is any pressure straightening machine 002 in the prior art. The pressure straightening machine 002 has a straightening platform 003 and a pressure end 004. The bottom plate 3 is set on the straightening platform 003. When in use, the pressure end 004 is driven to move closer to or away from the straightening platform 003 to complete the straightening operation of the workpiece to be straightened. It will not be repeated here.

[0040] The partition assembly includes a partition 7 and a connecting piece, and the partition 7 is detachably arranged in the accommodating groove 6 through the connecting piece; the partition 7 has a straightening surface I8, and the cross-sectional linear shape of the straightening surface I8 is consistent with the irregular linear shape of one side in the cross section of the workpiece 001 to be straightened; that is, the linear shape of the straightening surface I8 is consistent with the linear shape of the a-surface of the workpiece 001 to be straightened, and is formed by the concave top surface of the partition 7.

[0041] The partition plate assemblies are divided into several groups, and the corresponding partition plates 7 in the several groups of partition plate assemblies are arranged at intervals along the length direction of the accommodating groove 6, and the straightening surfaces I8 are oriented in the same direction; this is beneficial to the correction of the a-surface of the straightening workpiece 001.

[0042] The side wall of the receiving groove 6 is provided with an assembly hole 9, and the connecting member includes a bolt group (not shown in the figure). The bolts in the bolt group are correspondingly inserted into the assembly hole 9 and connected to the partition 7. The partition 7 is detachably fixed to the receiving groove 6 by the bolt group. Specifically, several groups of assembly holes 9 are provided along the entire length of the left side plate 4 and the right side plate 5. Each group of assembly holes 9 corresponds to a group of bolts. The bolt group in the connecting member includes two groups arranged on both sides of the receiving groove 6, so that the partition 7 is fastened and limited in a clamping manner on both the left side plate 4 and the right side plate 5 through the corresponding bolt group, and the structural reliability is better. It can also meet the needs of straightening workpieces of different lengths and sizes, and adjust the size and position of the partition 7 according to different structures and straightening accuracy.

[0043] The partition 7 is provided with an avoidance groove 10 located at the bottom of the straightening surface I8, and the notch of the avoidance groove 10 penetrates the straightening surface I8 upward; the avoidance groove 10 is a circular hole and the top is connected to the straightening surface I8. The avoidance groove 10 is used to accommodate the special-shaped part 1, improve the tolerance of the product, and improve the straightening efficiency and quality of the workpiece to be straightened.

[0044] During use, the side of the workpiece 001 to be straightened that is aligned with the straightening surface I8 in cross-section is supported by the straightening surface I8, that is, the a-side of the workpiece 001 to be straightened is placed on the straightening surface I8 of the partition 7. Specifically, the base is mounted on the straightening platform 003 of the straightening device, and several groups of partitions 7 are correspondingly arranged in the receiving grooves 6 of the base, with the straightening surface I8 facing upward, so that the a-side of the workpiece 001 to be straightened is opposite to the straightening surface I8, and the special-shaped portion 1 is located in the avoidance groove 10; the pressure end 004 of the straightening device is driven to make the a-side of the workpiece 001 to be straightened fit with the straightening surface I8, completing the straightening of the a-side and a'-side of the workpiece.

[0045] In this embodiment, the partition assembly also includes a sealing member 11, which is detachably arranged on the partition 7 and blocks the straightening surface I8, so that the partition 7 has an upward support surface 12; in this solution, the outer contour of the sealing member 11 is consistent with the shape of the accommodating groove 6 opened on the partition 7 and the shape of the straightening surface I8 connected thereto, and the dimensions are matched, specifically, the gap is within 5 mm, and the gap in this solution is 2 mm, so that after the sealing member 11 is embedded in the accommodating groove 6 and the concave position of the partition 7, the straightening surface I8 is blocked, and the top surface of the partition 7 and the top surface of the sealing member 11 serve as the support surface 12, and the support surface 12 is continuous and flat and roughly parallel to the horizontal plane, so as to enhance the straightening function of the plane.

[0046] When the sealing member 11 is set on the partition 7, the supporting surface 12 is used to support one of the planes of the workpiece 001 to be straightened, specifically the b-surface and b'-surface of the workpiece 001 to be straightened. When the sealing member 11 is removed from the partition 7, the straightening surface I8 is used to support a surface of the workpiece 001 to be straightened that is consistent with the cross-sectional linear shape of the straightening surface I8, specifically the a-surface of the workpiece 001 to be straightened.

[0047] During use, when the b-surface or b'-surface needs to be straightened, the sealing member 11 is set on the partition 7, and the support surface 12 is used to support the b-surface or b'-surface of the workpiece 001 to be straightened, and the pressure end 004 of the straightening equipment is driven to make the b-surface or b'-surface of the workpiece 001 to be straightened fit with the support surface 12 to complete the straightening of the b-surface and b'-surface of the straightening workpiece.

[0048] In this solution, when straightening the b-surface or the b'-surface, there is no need to dismantle the partition plate 7 and only the sealing member 11 needs to be adjusted, thereby improving construction efficiency.

[0049] In this embodiment, an auxiliary part 13 is also included, and the auxiliary part 13 has a straightening surface II14, and the cross-sectional linear shape of the straightening surface II14 is consistent with the irregular linear shape of another surface in the cross-section of the workpiece 001 to be straightened; that is, the linear shape of the straightening surface II14 is consistent with the linear shape of the c-surface and the corresponding side a-surface of the workpiece 001 to be straightened; wherein the auxiliary part 13 can be an independent long strip component or a block structure, and it is preferable to have the corresponding function of straightening the workpiece 001 to be straightened. It will not be repeated here. The auxiliary part 13 of this scheme is block-shaped and is correspondingly arranged at the bottom of the pressure end 004 when in use, which is more convenient to use; when in use, the auxiliary part 13 is arranged on the pressure end 004 of the straightening equipment or the workpiece 001 to be straightened, and the side of the workpiece 001 to be straightened that is consistent with the cross-sectional linear shape of the straightening surface II14 supports the straightening surface II14.

[0050] Specifically, when straightening the c-surface and the corresponding side a-surface of the workpiece 001 to be straightened, the a'-surface of the workpiece 001 to be straightened is set on the partition 7, so that the straightening surface Ⅱ14 of the auxiliary part 13 is opposite to the c-surface and the corresponding side a-surface of the workpiece 001 to be straightened, and the pressure end 004 of the straightening equipment drives the auxiliary part 13, so that the c-surface and the corresponding side a-surface of the workpiece 001 to be straightened are fitted with the straightening surface Ⅱ14 to complete the straightening of the c-surface and the corresponding side a-surface of the straightening workpiece. In this state, the a'-surface can also be straightened again, which is more efficient and has better product quality.

[0051] When applied to other solutions, the linear shapes of the straightening surface I8 and the straightening surface II14 are designed according to the structure of the special-shaped surface, which will not be described in detail here.

[0052] The present solution also discloses a straightening method for irregular sectional weldments, comprising a straightening device;

[0053] Straightening methods include:

[0054] S1. The bottom plate 3 of the straightening device is provided on the straightening platform 003 of the straightening device;

[0055] S2. A partition 7 having a straightening surface Ⅰ8 is provided on the bottom plate 3 of the straightening device;

[0056] S3. Remove the sealing member 11 on the partition 7 so that the workpiece to be straightened 001 conforms to the straightening surface Ⅰ8 and is disposed on the straightening surface Ⅰ8 of the partition 7;

[0057] The pressure end 004 of the straightening device is driven to press down the workpiece 001 to be straightened so as to straighten the side of the workpiece 001 that is conformed to the straightening surface I8;

[0058] S4 remove the workpiece to be straightened 001, the blocking member 11 on the partition 7 is reset, so that the workpiece to be straightened 001 is supported by the support surface 12, and the workpiece to be straightened 001 and the straightening surface Ⅱ14 conformal side facing upward;

[0059] S5. An auxiliary member 13 is provided on the workpiece to be straightened 001 so that the workpiece to be straightened 001 is opposite to the straightening surface Ⅱ14 and the conformal side of the straightening surface Ⅱ14;

[0060] The pressure end 004 of the straightening device is driven to press down the auxiliary part 13 to straighten the side of the workpiece 001 to be straightened that conforms to the straightening surface II 14;

[0061] S6. Remove the workpiece 001 to be straightened and straighten the remaining flat surfaces using the straightening equipment.

[0062] This solution first uses straightening equipment to straighten the a' surface of the workpiece 001 to be straightened, and simultaneously straightens the a surface that conforms to the straightening surface I8; then straightens the c surface and the corresponding side a surface of the straightening workpiece, and at this time straightens the a' surface at the same time, so that the straightening accuracy of the relative a surface and a' surface is higher and the workpiece quality is better. Then, the b surface or b' surface is straightened separately to complete the comprehensive straightening of the workpiece 001 to be straightened, and the overall efficiency is higher. During the pressure straightening process of irregular cross-section linear steel components, there is a problem that the irregular steel components cannot maintain their own levelness during the straightening process, resulting in difficulty in straightening and low work efficiency; this solution uses this device to straighten irregular linear weldments, which can effectively straighten the deformation of the weldments, is convenient to operate, improves work efficiency, and can also solve the subsequent straightening problems of the same type of linear weldments. Compared with the original correction tools and methods, this solution has lower economic costs, is easy to manufacture and simple to operate, and can simultaneously meet the multi-directional straightening of regular and irregular cross-section steel components, ensuring straightening quality and improving production efficiency.
