Description

Technical Field

[0001] This utility model relates to cold-bending profile production and processing equipment, specifically to a cold-bending profile guiding device for a roll forming mill. Background Technology

[0002] Cold-formed profiles, also known as cold-formed steel sections, are the main material for manufacturing lightweight steel structures. They possess various ultra-thin, rationally shaped, and complex cross-sections that cannot be produced by hot rolling. Due to the complexity of the cross-sectional shape of cold-formed profiles, and the greater differences in cross-sectional shape between different models, the material guiding device used in the production of cold-formed profiles using a roll forming mill typically employs multiple guide rollers to form an output channel. As the cold-formed profile passes through the output channel, each guide roller only contacts a small portion of the outer end of the profile, resulting in poor limiting and guiding effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a material guiding device for cold-bent profiles in a roll forming mill, which can play a better role in limiting and guiding materials when producing cold-bent profiles using a roll forming mill.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a guide device for cold-bent profiles in a roll forming mill, comprising a transverse limiting guide mechanism and a vertical limiting guide mechanism. The transverse limiting guide mechanism includes a left limiting component and a right limiting component. The left limiting component includes a plurality of left limiting wheels, the axles of which are vertical, and the right ends of each left limiting wheel cooperate to form a left limiting end face, which is adapted to the left end face of the cold-bent profile. The right limiting component includes a plurality of right limiting wheels, the axles of which are vertical, and the left ends of each right limiting wheel cooperate to form a right limiting end face, which is adapted to the right end face of the cold-bent profile. A horizontal limiting and guiding channel is set between the left limiting end face and the vertical limiting and guiding mechanism. The vertical limiting and guiding mechanism includes an upper limiting component and a lower limiting component. The upper limiting component includes several upper limiting wheels with horizontal axles, and the lower ends of each upper limiting wheel cooperate to form an upper limiting end face, which is adapted to the upper end face of the cold-formed profile. The lower limiting component includes several lower limiting wheels with horizontal axles, and the upper ends of each lower limiting wheel cooperate to form a lower limiting end face, which is adapted to the lower end face of the cold-formed profile. A vertical limiting and guiding channel is set between the upper and lower limiting end faces, and the horizontal limiting and guiding channel communicates with the vertical limiting and guiding channel. The left and right limiting components cooperate to limit the cold-formed profile horizontally, and the upper and lower limiting components cooperate to restrict the cold-formed profile vertically. The shape of each limiting component is adapted to the corresponding end face of the cold-formed profile, thereby improving the limiting and guiding effect on the cold-formed profile.

[0005] As an optional technical solution, there are at least two transverse limiting and guiding mechanisms and / or vertical limiting and guiding mechanisms, which are distributed along the discharge direction of the roll mill. Each transverse limiting and guiding channel and the vertical limiting and guiding channel form a total guiding channel along the discharge direction of the roll mill.

[0006] As an optional technical solution, the lateral limiting and guiding mechanism and the vertical limiting and guiding mechanism are arranged alternately. The alternating arrangement of the lateral limiting and guiding mechanism and the vertical limiting and guiding mechanism provides more stable limiting and guiding of the cold-bent profile.

[0007] As an optional technical solution, the left limiting component, right limiting component, upper limiting component, and lower limiting component constitute a first limiting mechanism. The first limiting mechanism includes a first limiting frame and shaping wheels. A limiting shaft is provided on the first limiting frame, and several shaping wheels are provided on the limiting shaft. Each shaping wheel abuts against the corresponding side end face of the cold-formed profile. The left, right, upper, and lower limiting wheels are all shaping wheels. Through multiple shaping wheels of the same or different diameters, a limiting end face adapted to the shape of the cold-formed profile end face is formed.

[0008] As an optional technical solution, the left limiting component, right limiting component, upper limiting component, and lower limiting component constitute a second limiting mechanism. The second limiting mechanism includes a second limiting frame with several guide holes arranged along a straight line. Each guide hole contains a guide rod, which is parallel to each other and can move along its respective guide hole. A shaping wheel is provided at the end of each guide rod, and each shaping wheel abuts against the corresponding side end face of the cold-formed profile. The left limiting wheel, right limiting wheel, upper limiting wheel, and lower limiting wheel are all shaping wheels. By adjusting the position of each shaping wheel, multiple shaping wheels can form a limiting end face that matches the shape of the cold-formed profile end face.

[0009] As an optional technical solution, the guide hole is a threaded hole, the guide rod is a threaded rod and is threadedly engaged with the guide hole, the end of the guide rod is provided with a wheel frame, the guide rod and the wheel frame are rotatably connected and adjacent wheel frames are in contact with each other, and each wheel frame is provided with a shaping wheel.

[0010] As an optional technical solution, the outer surface of the shaping wheel is fitted with an elastic washer, and the outer end faces of adjacent elastic washers are connected to form a limiting end face that is adapted to the corresponding end face of the cold-bent profile.

[0011] As an optional technical solution, the thickness of the shaping wheel gradually decreases from the inside to the outside.

[0012] Compared with the prior art, the present invention has the following advantages: In the material guiding device of this application, the wheel diameter or height of each upper limit wheel of the upper limit component is adaptively adjusted according to the shape of the upper end face of the cold-bent profile, and each upper limit wheel is respectively attached to different positions of the upper end face of the cold-bent profile. According to the shape of the lower end face of the cold-bent profile, the wheel diameter or height of each lower limit wheel of the lower limit component is adaptively adjusted, and each lower limit wheel is respectively attached to different positions of the lower end face of the cold-bent profile. The upper limit component and the lower limit component cooperate to achieve the effect of limiting and guiding the cold-bent profile in the height direction; according to the shape of the left end face of the cold-bent profile, the wheel diameter or left and right position of each left limit wheel of the left limit component is adaptively adjusted. Adjustments are made so that each left limiting wheel is engaged with different positions on the left end face of the cold-formed profile. According to the shape of the right end face of the cold-formed profile, the wheel diameter or left and right position of each right limiting wheel of the right limiting component is adaptively adjusted. Each right limiting wheel is engaged with different positions on the right end face of the cold-formed profile. The left limiting component and the right limiting component work together to limit and guide the cold-formed profile in the left and right directions. This makes the cold-formed profile completely restricted in all directions during the material guiding and discharging process, effectively improving the material guiding and discharging effect of the cold-formed profile. Moreover, according to different models of cold-formed profiles, each upper limiting wheel, lower limiting wheel, left limiting wheel, and right limiting wheel can be adjusted specifically so that each end face of the cold-formed profile is limited.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0020] Example

[0021] like Figures 1-4 As shown, a cold-bent profile guiding device for a roll forming mill includes a transverse limiting guiding mechanism 1 and a vertical limiting guiding mechanism 2. The transverse limiting guiding mechanism 1 is used to limit and guide the cold-bent profile in the transverse direction, and the vertical limiting guiding mechanism 2 is used to limit and guide the cold-bent profile in the vertical direction.

[0022] The transverse limiting and guiding mechanism 1 includes a left limiting component 11 and a right limiting component 12. The left limiting component 11 includes a plurality of left limiting wheels 111, which are arranged vertically. The right ends of each left limiting wheel 111 cooperate to form a left limiting end face, which is adapted to the left end face of the cold-formed profile. The right limiting component 12 includes a plurality of right limiting wheels 121, which are arranged vertically. The right limiting wheels 121 have a left limiting end face that fits the left end face of the cold-formed profile. The left end face is fitted to form the right limiting end face, which is adapted to the right end face of the cold-bent profile. A transverse limiting guide channel is set between the left limiting end face and the right limiting end face. When the cold-bent profile passes through the transverse limiting guide channel, the left end face of the cold-bent profile abuts against the left limiting end face, and the right end face of the cold-bent profile abuts against the right limiting end face. The left limiting component 11 and the right limiting component 12 cooperate to limit the cold-bent profile in the transverse direction.

[0023] The vertical limiting and guiding mechanism 2 includes an upper limit component 21 and a lower limit component 22. The upper limit component 21 includes several upper limit wheels 211, which are laterally distributed and whose lower ends cooperate to form an upper limit end face, which is adapted to the upper end face of the cold-bent profile. The lower limit component 22 includes several lower limit wheels 221, which are also laterally distributed and whose upper ends cooperate to form a lower limit end face, which is adapted to the lower end face of the cold-bent profile. A vertical limiting and guiding channel is set between the upper limit end face and the lower limit end face. When the cold-bent profile passes through the vertical limiting and guiding channel, the upper end face of the cold-bent profile abuts against the upper limit end face, and the lower end face of the cold-bent profile abuts against the lower limit end face. The upper limit component 21 and the lower limit component 22 cooperate to limit the cold-bent profile in the vertical direction.

[0024] The horizontal limiting guide channel is connected to the vertical limiting guide channel to form a total guide channel. With the cooperation of the various components of the guide device, the cold-bent profile moves along the total guide channel to achieve limiting and guiding.

[0025] To achieve better material guiding effect, there are at least two transverse limiting material guiding mechanisms 1 and / or vertical limiting material guiding mechanisms 2. Each transverse limiting material guiding mechanism 1 and each vertical limiting material guiding mechanism 2 is distributed along the discharge direction of the roll mill. Each transverse limiting material guiding channel is connected to each vertical limiting material guiding channel and forms a total guiding channel along the discharge direction of the roll mill.

[0026] In a preferred embodiment, the lateral limiting guide mechanism 1 and the vertical limiting guide mechanism 2 are arranged alternately. During the cold bending profile discharge process, they are alternately guided by the lateral limiting and the vertical limiting to avoid bending and deviation.

[0027] In some embodiments, the left limiting component 11, the right limiting component 12, the upper limiting component 21, and the lower limiting component 22 are all in the form of a first limiting mechanism. Please refer to [link / reference]. Figures 1-3 The first limiting mechanism includes a first limiting frame and shaping wheels. The first limiting frame is provided with a limiting shaft, and the limiting shaft is provided with several shaping wheels. The upper limiting wheel 211, the lower limiting wheel 221, the left limiting wheel 111, and the right limiting wheel 121 are all shaping wheels.

[0028] Please see Figure 2 In the upper limit assembly 21, the limiting shaft is horizontally positioned, and several upper limit wheels 211 are provided on the limiting shaft. The diameter of each upper limit wheel 211 varies according to the shape of the cold-formed profile along the length of the limiting shaft. The lower end of each upper limit wheel 211 forms an upper limit end face that adapts to the shape of the upper end face of the cold-formed profile. Similarly, the diameter of each lower limit wheel 221 in the lower limit assembly 22 varies according to the shape of the cold-formed profile along the length of the limiting shaft. The upper end of each lower limit wheel 221 forms a lower limit end face that adapts to the shape of the lower end face of the cold-formed profile.

[0029] Please see Figure 3 In the left limiting component 11, the limiting shaft is vertically positioned, and several left limiting wheels 111 are set on the limiting shaft. According to the shape of the cold-formed profile in the length direction of the limiting shaft, the diameter of each left limiting wheel 111 changes accordingly, and the right end of each left limiting wheel 111 forms a left limiting end face that adapts to the shape of the left end of the cold-formed profile. The right limiting component 12 is similar, and the left end of each right limiting wheel 121 of the right limiting component 12 forms a right limiting end face that adapts to the shape of the right end of the cold-formed profile.

[0030] The first limit frame of each limit component is set on the base. Optionally, the positions of the left limit component 11 and the right limit component on the base can be adjusted, and the heights of the upper limit component 21 and the lower limit component 22 can be adjusted.

[0031] As an optional implementation, the limiting shafts of each limiting component can also be connected to a power device to achieve a drive-type material guiding of the cold-bent profile.

[0032] In other embodiments, the left limiting component 11, the right limiting component 12, the upper limiting component 21, and the lower limiting component 22 are all in the form of a second limiting mechanism. The second limiting mechanism includes a second limiting frame 31, on which a plurality of guide holes are provided along a straight line. A guide rod 32 is provided in each guide hole. Each guide rod 32 is parallel to each other and can move along the guide hole. A shaping wheel is provided at the end of the guide rod 32. Each shaping wheel abuts against the corresponding side end face of the cold-bent profile. The left limiting wheel 111, the right limiting wheel 121, the upper limiting wheel 211, and the lower limiting wheel 221 are all shaping wheels.

[0033] For details, please refer to Figure 4 Taking the upper limit component 21 as an example, the second limit frame 31 of the upper limit component 21 is provided with several guide holes, and a guide rod 32 is provided in the guide hole. A shaping wheel is provided at the bottom end of the guide rod 32. The guide rod 32 can move along the guide hole to adjust the height of the shaping wheel. Adjusting the height of the shaping wheel makes the lower end of each shaping wheel form an upper limit end face that matches the shape of the upper end face of the cold-bent profile.

[0034] The lower limit component 22 is similar to the upper limit component 21, and the guide holes of the left limit component 11 and the right limit component 12 are distributed vertically.

[0035] Furthermore, the guide hole is a threaded hole, and the guide rod 32 is a threaded rod that is threaded into the guide hole. Rotating the guide rod 32 allows it to move along the guide hole. The end of the guide rod 32 used to mount the shaping wheel is equipped with a wheel frame 33. The guide rod 32 and the wheel frame 33 are rotatably connected, and adjacent wheel frames 33 engage with each other, ensuring that the wheel frame 33 does not rotate when the guide rod 32 rotates. The rotation of the guide rod 32 only moves the wheel frame 33 along its length for adjustment. Two limiting guide plates are also provided on the second limiting frame 31 of each limiting component. Each wheel frame 33 is located between the two limiting guide plates. Under the combined action of the two limiting guide plates and adjacent wheel frames 33, the rotation of the guide rod 32 can move the wheel frame 33, but it does not cause the wheel frame 33 to rotate. The shaping wheel is mounted on the wheel frame 33.

[0036] As an optional implementation, both the first and second limiting mechanisms have elastic washers fitted around their forming wheels. The outer end faces of adjacent elastic washers are in contact, forming a limiting end face that fits the corresponding end face of the cold-formed profile. The elastic washers not only prevent direct contact between the forming wheels and the cold-formed profile, protecting the profile, but also, by selecting elastic washers with suitable outer end faces, ensure that the formed limiting end face fits more closely to the outer end face of the cold-formed profile, resulting in better material guiding.

[0037] As another alternative implementation method, the thickness of the shaping wheel gradually decreases from the inside to the outside, and the thickness at the outer edge of the shaping wheel is even smaller, which helps to make the shaping wheel abut against and fit the outer end face of the cold-bent profile. Multiple shaping wheels working together can achieve a better material guiding effect.
