Description

Technical Field

[0001] The utility model relates to the technical field of rolled piece straightening, in particular to a channel steel rolled piece straightening machine. Background Art

[0002] A channel steel straightener is a device specifically designed to improve the straightness of rolled channel steel. During the rolling, transportation, heat treatment, and cooling processes, channels may become bent or twisted. The straightener's function is to physically eliminate these defects, ensuring that the straightness of the channel steel meets specific industry standards.

[0003] A Chinese patent with the announcement number CN219985811U discloses a channel steel rolled piece straightening machine, comprising a base, support legs welded to the four corners of the bottom end of the base, a lifting mechanism fixedly mounted on the top end of the base, a driving mechanism provided at the bottom end of the base, and the lifting mechanism comprising a fixed frame, a threaded rod, a first movable member, and a second movable member, and a fixed frame welded to the four corners of the top end of the base. The straightening machine is provided with a lifting mechanism and a driving mechanism that are used in conjunction with each other, and the output end of the servo motor drives the first rotating rod to rotate, so that the two sets of first bevel gears rotate synchronously, the two sets of third bevel gears rotate synchronously, the two sets of second bevel gears rotate synchronously, the four sets of fourth bevel gears rotate synchronously, and the four threaded rods rotate synchronously, and then the first movable member and the second movable member move closer to or farther away from each other, thereby changing the distance between the upper roller and the lower roller, and can be well applied to profile rolled pieces of different thicknesses.

[0004] However, the above technical solution has the following shortcomings: the straightening machine still uses traditional multiple straightening rollers to directly squeeze and roll the channel steel at the same time to achieve the straightening effect. This method makes it difficult to obtain the bending condition and bending data of the channel steel in a timely manner. The channel steel needs to be transported and straightened for the entire process before data detection is performed, and the deviated parts of the channel steel cannot be processed separately and effectively, which reduces the working efficiency of the equipment. Utility Model Content

[0005] The purpose of the utility model is to address the problems existing in the background technology and propose a channel steel rolled piece straightening machine. By performing multiple inspections on the channel steel rolled piece and carrying out targeted straightening treatment on the parts to be straightened, the working quality and efficiency of the equipment are improved, while ensuring the stability of the channel steel during processing.

[0006] The technical solution of the utility model is a channel steel rolled piece straightening machine, comprising a base and a supporting mechanism; a machine base is provided on the base, a hydraulic rod is provided above the machine base, and the hydraulic rod is driven and connected to a pressure block; the supporting mechanism comprises two supporting platforms symmetrically distributed on the machine base, a positioning assembly arranged on the supporting platform, two horizontally rotatable screws connected to the inside of the machine base, two movable seats distributed left and right on the machine base and both threadedly connected to the screws, and an auxiliary supporting assembly arranged on the movable seat, the positioning assembly comprises a first motor arranged on the supporting platform, a bidirectional threaded rod rotatably connected to the support platform, two threaded blocks symmetrically distributed and both threadedly connected to the bidirectional threaded rod, and a positioning plate arranged on the threaded block, the first motor is drive-connected to the bidirectional threaded rod, and the threaded block is slidably arranged inside the support platform.

[0007] Preferably, the auxiliary support assembly includes a first cylinder arranged on the movable seat, a support plate drivingly connected to the first cylinder, and a counterweight block arranged on the support plate.

[0008] Preferably, two vertically distributed second cylinders are provided on the machine base, and the second cylinders are driven and connected to a lifting plate.

[0009] Preferably, a rotating mechanism is provided on the base, and the rotating mechanism includes two sliding seats symmetrically distributed on the base, a second motor provided on the sliding seat, a rotating block driven by the second motor, and a clamping assembly provided inside the rotating block.

[0010] Preferably, the base is provided with two third cylinders which are respectively arranged horizontally on the base, and the third cylinders are drivingly connected to the sliding seat.

[0011] Preferably, the clamping assembly includes two first springs distributed in an annular array inside the rotating block, a top block arranged on the first spring, four second springs distributed up and down inside the rotating block, a side block arranged on the second spring and slidingly connected to the top block, a fixed plate arranged on the side block, and a clamping block arranged on the fixed plate.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1.

DETAILED DESCRIPTION

[0021] Example 1

[0022] like Figures 1-4 As shown, a channel steel rolled piece straightening machine proposed in this embodiment includes a base 1 and a supporting mechanism; a machine base 2 is provided on the base 1, and a hydraulic rod 27 is provided above the machine base 2, and the hydraulic rod 27 is driven and connected to a pressure block 28, and the hydraulic rod 27 is driven and connected to a hydraulic cylinder (not shown), and the hydraulic cylinder can move horizontally to ensure that it can drive the pressure block 28 to straighten different positions of the channel steel.

[0023] like Figure 1-Figure 3 As shown, the support mechanism includes two support platforms 3 symmetrically distributed on the machine base 2, a positioning assembly arranged on the support platform 3, two horizontally rotating screws 12 connected to the inside of the machine base 2, two movable bases 8 distributed on the left and right sides of the machine base 2 and both threadedly connected to the screws 12, and an auxiliary support assembly arranged on the movable base 8.

[0024] The positioning assembly includes a first motor 4 arranged on the support platform 3, a bidirectional threaded rod 5 rotatably connected to the support platform 3, two symmetrically distributed threaded blocks 6 that are both threadedly connected to the bidirectional threaded rod 5, and a positioning plate 7 arranged on the threaded block 6. The first motor 4 is driven and connected to the bidirectional threaded rod 5, and the threaded block 6 is slidably arranged inside the support platform 3. The bidirectional threaded rod 5 is driven to rotate by the first motor 4, and the bidirectional threaded rod 5 is screwed together with the threaded block 6, and then the threaded block 6 drives the two positioning plates 7 to approach each other until the two positioning plates 7 fix the channel steel. At this time, the channel steel is located at the center position of the support platform 3, realizing the placement and positioning of the channel steel, so as to carry out data detection and straightening processing, and has good practicality.

[0025] The auxiliary support assembly includes a first cylinder 9 arranged on the movable seat 8, a support plate 10 driven by the first cylinder 9, and a counterweight block 11 arranged on the support plate 10. The counterweight block 11 is used to ensure that when the support plate 10 is under pressure, it will not suffer the disadvantage of irreversible deformation due to excessive pressure on one side.

[0026] In this embodiment, the support platform 3 is provided to support the channel steel during the straightening process, and the support plate 10 is provided to provide auxiliary support. When the pressing block 28 is pressed down at the middle of the channel steel or near the middle of the channel steel, the elastic deformation of the channel steel body causes an inward concave condition, and then the two ends of the channel steel change from surface contact with the support platform 3 to line contact, which may cause the channel steel to shift. The support plate 10 provided can provide a force-bearing area for the channel steel to ensure the stability of the channel steel.

[0027] Example 2

[0028] like Figure 1 and Figure 4 As shown, a channel steel rolled piece straightening machine proposed in this embodiment, compared with the first embodiment, in this embodiment, two vertically distributed second cylinders 13 are provided on the machine base 2, the second cylinder 13 is driven and connected to the lifting plate 14, and a rotating mechanism is provided on the base 1, which includes two sliding seats 15 symmetrically distributed on the base 1, a second motor 17 arranged on the sliding seat 15, a rotating block 18 driven and connected to the second motor 17, and a clamping assembly arranged inside the rotating block 18.

[0029] Two third cylinders 16 are provided on the base 1 and are respectively located horizontally on the base 1 . The third cylinders 16 are drivingly connected to the sliding seat 15 .

[0030] The clamping assembly includes two first springs 19 distributed in a circular array inside the rotating block 18, a top block 20 arranged on the first spring 19, four second springs 21 distributed up and down inside the rotating block 18, a side block 22 arranged on the second springs 21 and slidingly connected to the top block 20, a fixed plate 23 arranged on the side block 22, and a clamping block 24 arranged on the fixed plate 23.

[0031] In this embodiment, when the channel steel rolled piece needs to be rotated to straighten different surfaces, the second cylinder 13 is first used to drive the lifting plate 14 to lift the channel steel. Then, the third cylinder 16 is activated to drive the sliding seat 15 to approach the two ends of the channel steel and squeeze it. During the squeezing, the channel steel pushes the top block 20 and compresses the first spring 19, and then the top block 20 and the two pressed and fitted inclined surfaces of the side blocks 22 slide relative to each other. Under the action of the second spring 21, the side blocks 22 approach the surfaces near the two ends of the channel steel until the clamping blocks 24 squeeze and fix the channel steel. Then, the second motor 17 is activated to drive the rotating block 18 to rotate, and the rotating block 18 drives the channel steel to rotate. After the rotation is completed, it is placed back on the support table 3 by the second cylinder 13.

[0032] Example 3

[0033] like Figure 1 As shown, the present embodiment proposes a channel steel rolled workpiece straightening machine. Compared to the first embodiment, in this embodiment, a mounting frame 25 is provided on the base 1. A detector 26 is provided on the mounting frame 25 for horizontal movement. The detector 26 is provided with a curvature detection sensor, and the sensor is located directly below the channel steel rolled workpiece. After each pressing and rotation, the channel steel is inspected, and the detected data is transmitted to a computer terminal (not shown) via an external controller. The computer automatically controls the position and depth of the hydraulic rod 27 and the pressure block 28 required to press down based on the curvature of the workpiece to complete the straightening process.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
