Description

Technical Field

[0001] This utility model relates to a forming equipment for brackets, and more particularly to a bracket profile correction and shaping device. Background Technology

[0002] Seismic bracing and greenhouse supports are types of supports that limit the displacement of auxiliary electromechanical engineering facilities, control the vibration of these facilities, and transfer loads to the load-bearing structure. Seismic bracing should provide reliable protection for building electromechanical engineering facilities during earthquakes, withstanding seismic forces from any horizontal direction. Channel steel is a long strip of steel with a U-shaped cross-section. It belongs to carbon structural steel for construction and machinery, and is a complex-section steel material with a U-shaped cross-section.

[0003] For the structure of the channel steel profile used in the existing support, please refer to [reference needed]. Figure 9 The sheet metal forming process using cold bending technology includes: first forming the small edge → then forming the flanging edge → finally forming the upright edge. See [link / reference needed]. Figure 10 This is a flowchart of the vertical edge forming process. Keeping the top edge of the profile constant, the two sides are gradually bent downwards from horizontal to form the final structure shown in step 8. After step 7, the left and right vertical plates of the profile are tilted outwards. When proceeding to step 8, a specific method is required. Figure 11 The equipment shown performs forming. An upper limit roller is located above the top edge of the profile, and a lower limit roller is located below the top edge. Because the lower limit roller must avoid the left and right flanges of the profile, only the middle part of the lower limit roller abuts against the bottom surface of the top edge of the profile. Left and right vertical rollers respectively roll the two vertical edges, allowing them to deform from an inclined state to a vertical state. However, because the left and right sides of the top edge of the profile are not restrained by the lower limit roller, when the two vertical plates are squeezed by the two vertical rollers, the top edges that are not restrained will be forced to deform and tilt downwards. See [link to relevant documentation] for the stress state. Figure 12 (a) The position indicated by the arrow in the middle results in the final profile after step 8 being... Figure 12 (b) At this point, the top edge of the profile bends downwards on both sides, resulting in a bend that is higher in the middle and lower on both sides. The surface flatness of the top edge is insufficient. At the same time, due to the plastic deformation of the vertical edge of the profile, the vertical edge is still slightly tilted outwards. The profile at this point cannot meet the user's requirements and cannot achieve the desired results. Figure 8 The structure shown requires the profile to be modified and shaped. However, the current shaping equipment in the industry cannot meet the needs of top edge shaping. Therefore, there is an urgent need to provide a device that can better solve the problem of top edge shaping of profiles. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bracket profile correction and shaping device that can correct and shape the top edge and vertical edge of a reasonably designed profile.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a bracket profile correction and shaping device, including a base, wherein a first trimming device and a second trimming device are provided on the base along the moving direction of the profile.

[0006] The first trimming device is provided with a first horizontal pressure upper roller, a first horizontal pressure lower roller, a first vertical pressure left roller, and a first vertical pressure right roller on the upper, lower, left, and right sides of the profile. The roller surface of the first horizontal pressure upper roller is provided with an inwardly recessed top edge correction groove.

[0007] The second trimming device is provided with a second horizontal pressure upper roller, a second horizontal pressure lower roller, a second vertical pressure left roller, and a second vertical pressure right roller on the upper, lower, left, and right sides of the profile, and the roller surface of the second horizontal pressure upper roller is horizontal.

[0008] As a preferred technical solution, the top edge correction groove is provided with a top edge positioning plane in the middle, and the top edge positioning plane is provided with downward inclined top edge limiting slopes on both sides.

[0009] As a preferred technical solution, the roller surfaces of the second vertical pressure left roller and the second vertical pressure right roller are vertical.

[0010] As a preferred technical solution, the first trimming device is provided with first fixed frames on the left and right sides of the profile, and a first upper roller pressure shaft and a first lower roller pressure shaft are arranged vertically between the two first fixed frames. The first horizontal pressure upper roller is installed on the first upper roller pressure shaft, the first horizontal pressure lower roller is installed on the first lower roller pressure shaft, the first vertical pressure left roller is located on the left side of the profile through the first left roller pressure shaft, and the first vertical pressure right roller is located on the right side of the profile through the first left roller pressure shaft.

[0011] As a preferred technical solution, the second trimming device is provided with second fixed frames on the left and right sides of the profile, and a second upper roller and a second lower roller are arranged vertically between the two second fixed frames. The second horizontal upper roller is installed on the second upper roller, the second horizontal lower roller is installed on the second lower roller, the second vertical left roller is located on the left side of the profile through the second left roller, and the second vertical right roller is located on the right side of the profile through the second left roller.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: This utility model provides a novel correction and shaping device that can solve the problem of the top edge protruding in the middle and the sides being low during the forming process of channel steel profiles.

The structure design is reasonable and the accuracy is high. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figure 1 and Figure 2 As shown, the bracket profile correction and shaping device includes a base 10. The base 10 is provided with a first trimming device 20 and a second trimming device 30 along the moving direction of the profile. The first trimming device 20 is used to perform a first micro-deformation on the profile, and the second trimming device 30 is used to perform a second shaping on the profile. This application adopts a two-step process to gradually correct and shape the profile, so that the top edge and upright plate of the profile are gradually shaped, which can ensure the flatness of the profile surface and ensure that the shape shaping meets the standards.

[0029] If the second shaping method is used directly for shaping, creases are easily created on the top edge surface. Furthermore, the profile exhibits plastic deformation, and the shaped profile will have a certain degree of recovery, making it impossible to fully achieve the desired result. Figure 9 The profile shown is shown. However, this application utilizes the first trimming device 20 and the second trimming device 30 in combination to achieve good flatness and ensure that the profile meets the required standards through two-step shaping.

[0030] See Figure 3The first trimming device 20 is equipped with a first horizontal upper roller 21, a first horizontal lower roller 22, a first vertical left roller 23, and a first vertical right roller 24 located above, below, left, and right of the profile. The rotation axes of the first horizontal upper roller 21 and the first horizontal lower roller 22 are horizontal, while the rotation axes of the first vertical left roller 23 and the first vertical right roller 24 are vertical. The first horizontal upper roller 21, the first horizontal lower roller 22, the first vertical left roller 23, and the first vertical right roller 24 cooperate to extrude the top edge, bottom edge, and left vertical edge of the profile. The right vertical plate undergoes the first micro-shaping process. The roller surface of the first horizontal pressure roller 21 is provided with an inwardly recessed top edge correction groove 25. The top edge correction groove 25 is used to assist in the shaping of the top edge, achieving a small-amplitude shaping and avoiding large-amplitude shaping that would result in creases on the surface. The roller surfaces of the first vertical pressure roller 23 and the first vertical pressure roller 24 are provided with vertical edge correction slopes 26 that slope downwards and outwards. The vertical edge correction slopes 26 achieve the purpose of shaping the vertical edge inwards by pressing the vertical edge downwards.

[0031] See Figure 4 The top edge correction groove 25 has a top edge positioning plane 25a in the middle, which corresponds to the upward protrusion in the middle of the profile. The top edge positioning plane 25a has downward inclined top edge limiting slopes 25b on both sides, which correspond to the downward bending parts on both sides of the profile. The inclination angle of the top edge limiting slopes 25b is greater than the bending angle of the profile. The top edge positioning plane 25a and the top edge limiting slopes 25b are smoothly connected.

[0032] The first shaping principle is as follows: the first vertical left roller 23 and the first vertical right roller 24 respectively squeeze the left and right vertical edges of the profile. In order to reserve space for the recovery deformation of the profile, the vertical edge correction slope 26 will gradually squeeze the left and right vertical plates inward, causing them to deform inward and change from an inclined state to a vertical state. At the same time, the first horizontal upper roller 21 squeezes the top edge of the profile, and the middle of the top edge of the profile contacts and abuts against the top edge positioning plane 25a. The first horizontal lower roller 22 squeezes the left and right bottom edges of the profile. During the squeezing process, the left and right vertical edges will be displaced upward through the bottom edges, that is, the left and right sides of the top edge will be lifted upward. See the force state. Figure 5 (a) Continue until the top edge completely contacts the top edge limiting slope 25b on both the left and right sides. See the image for the state of the profile after forming. Figure 5 (b) The top edge of the profile also has a slight inclination on both sides. After the first shaping, the top edge is not corrected in one go, but only partially corrected, leaving the other part of the correction to be completed by the second trimming device 30.

[0033] See Figure 6 and Figure 7The second trimming device 30 is located on the top, bottom, left, and right sides of the profile and includes a second horizontal upper roller 31, a second horizontal lower roller 32, a second vertical left roller 33, and a second vertical right roller 34. The rotation axes of the second horizontal upper roller 31 and the second horizontal lower roller 32 are horizontal, while the rotation axes of the second vertical left roller 33 and the second vertical right roller 34 are vertical. The second horizontal upper roller 31, the second horizontal lower roller 32, the second vertical left roller 33, and the second vertical right roller 34 perform a second shaping on the top edge, bottom edge, left vertical edge, and right vertical plate of the profile in conjunction with the extrusion profile. The roller surface of the second horizontal upper roller 31 is horizontal, while the roller surfaces of the second vertical left roller 33 and the second vertical right roller 34 are vertical. The second trimming device 30 is a further shaping process after the first shaping step.

[0034] The principle behind the second cosmetic procedure is:

[0035] The second vertical left roller 33 and the second vertical right roller 34 respectively press the left and right vertical edges of the profile, while the second horizontal upper roller 31 presses the top edge of the profile. The middle of the top edge of the profile contacts and abuts against the roller surface of the second horizontal upper roller 31. The second horizontal lower roller 32 presses the left and right bottom edges of the profile. During the pressing process, the bottom edges cause the left and right vertical edges to shift upward, that is, the left and right sides of the top edge are lifted upward. See the force state for details. Figure 8 (a) Stop when the top edge and both sides are fully in contact with the roller surface of the second horizontal pressure roller 31. Since the second horizontal pressure roller 31 is horizontal at this time, the top edge and both sides can also be made nearly horizontal. See the profile state after forming. Figure 8 (b).

[0036] The first trimming device 20 has first fixed frames on the left and right sides of the profile, respectively. Between the two first fixed frames are a first upper roller and a first lower roller arranged vertically. The first horizontal upper roller 21 is mounted on the first upper roller, and the first horizontal lower roller 22 is mounted on the first lower roller. The first vertical left roller 23 is located on the left side of the profile via the first left roller, and the first vertical right roller 24 is located on the right side of the profile via the first left roller. In this embodiment, the first lower roller is connected to a motor, and the first upper roller and the first lower roller are driven by a chain or gear. The first horizontal upper roller 21 and the second horizontal upper roller 31 are driving rollers, while the first vertical left roller 23 and the first vertical right roller 24 are driven rollers without power drive.

[0037] The second trimming device 30 has second fixed frames on the left and right sides of the profile, respectively. A second upper roller and a second lower roller are arranged vertically between the two second fixed frames. The second horizontal upper roller 31 is mounted on the second upper roller, and the second horizontal lower roller 32 is mounted on the second lower roller. The second vertical left roller 33 is located on the left side of the profile via the second left roller, and the second vertical right roller 34 is located on the right side of the profile via the second left roller. In this embodiment, the second lower roller is connected to a motor, and the second upper roller and the second lower roller are driven by a chain or gear. The second horizontal upper roller 31 is the driving roller, while the second vertical left roller 33 and the second vertical right roller 34 are driven rollers without power drive.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
