Description

Technical Field

[0001] The present application relates to the field of steel plate rolling equipment, and in particular to a plate rolling machine used for steel plate processing. Background Art

[0002] Plate rolling machine is a very important metal processing equipment. It uses working rollers to bend the plate into shape. It can process parts of different shapes such as cylindrical parts, conical parts, elliptical parts, arc parts, etc. It can process various metal plates, including plates of different materials and thicknesses, to meet diverse processing needs. In particular, the bent steel plates processed by the plate rolling machine have been widely used in boilers, ships, petrochemicals, aviation, hydropower, decoration, metal structures and other industries.

[0003] The working principle of the plate rolling machine is to use external forces such as hydraulic pressure and mechanical force to move the working rollers, thereby bending or rolling the plate into shape. According to the rotation and position changes of the working rollers of different shapes, it can process parts of various shapes.

[0004] During the operation of the plate rolling machine, the feed mechanism first ensures that the plate enters smoothly. Then, the guide rollers clamp the plate to prevent it from slipping during the coiling process. The main drive roller is driven by a motor or hydraulic device to make the whole system work. At the same time, the elastic roller will apply a certain amount of pressure to increase the friction of the coiling. The plate rolling machine usually also has an adjustable roller shaft to adjust the shape of the coil. As the main drive roller rotates, the plate gradually curls into shape and is finally sent out through the discharge mechanism.

[0005] Regarding the above-mentioned related technologies, the discharging mechanism of the plate rolling machine mostly uses a roller conveyor belt to transmit the discharging material. When processing some thick and high-curling steel plates, the processed curled steel plates are difficult to be transferred to the discharging mechanism smoothly and gently, which affects the service life of the discharging mechanism. Utility Model Content

[0006] In order to improve the problems existing in the process of transferring the processed curled steel plate to the discharging mechanism and reduce the impact of the discharging on the service life of the discharging mechanism, the present application provides a plate rolling machine for steel plate processing.

[0007] The plate rolling machine for steel plate processing provided in this application adopts the following technical solution:

[0008] A plate rolling machine for steel plate processing, comprising a plate rolling body and a discharge mechanism arranged on the discharge side of the plate rolling body, and also comprising an auxiliary discharge mechanism, the auxiliary discharge mechanism comprising a mobile gantry arranged on the discharge side of the plate rolling body, a lifting assembly installed on the mobile gantry and a plate fixing assembly arranged on the lifting assembly, the mobile gantry can move along the discharge direction of the discharge mechanism, and the plate fixing assembly is used for temporarily connecting the rolled steel plate.

[0009] By adopting the above technical solution, during the plate rolling operation, as the plate is rolled, the plate fixing assembly is adjusted to be temporarily connected to the rolled plate, and then as the plate continues to roll, the lifting assembly is gradually adjusted to ensure that when the rolling is completed, the lifting assembly provides the main pulling force, so that the rolled steel plate can be smoothly and gently transferred to the discharging mechanism as the mobile gantry moves, effectively avoiding the phenomenon of the rolled steel plate falling heavily or even hitting the discharging mechanism after the rolling is completed, which helps to extend the service life of the discharging mechanism.

[0010] Optionally, the plate fixing assembly includes an electromagnet.

[0011] By adopting the above technical solution, the steel plate is temporarily fixed by an electromagnet, which is not only convenient for adsorption, but also convenient for detachment, and is simple and practical.

[0012] Optionally, the plate fixing assembly further comprises two clamping arms hinged on the lifting assembly, the clamping ends of the two clamping arms are both provided with the electromagnets, and the two electromagnets are arranged opposite to each other.

[0013] By adopting the above technical solution, two sets of electromagnets can be used to temporarily fix the curled steel plate, so that it can be adsorbed and clamped from both sides, which helps to improve the temporary fixing effect. Before adsorbing to the curled steel plate, the two electromagnets can be adjusted to the same magnetic poles so that the two clamping arms can be opened to the maximum extent, which is convenient for clamping.

[0014] Optionally, a connecting rod extending toward the other clamping arm is provided on one of the clamping arms, and a limiting plate is transversely provided at the end of the connecting rod.

[0015] By adopting the above technical solution, the connecting rod and the limit plate are used to limit the opening and closing angles of the two clamping arms, so as to avoid the problem of excessive opening of the clamping arms when the two electromagnets have the same magnetic poles.

[0016] Optionally, a tension spring is further connected between the two clamping arms.

[0017] By adopting the above technical solution, the provided tension spring helps the two clamping arms to cooperate and clamp.

[0018] Optionally, a flexible cushion layer is provided on the working surface of the electromagnet for adsorbing the curled steel plate.

[0019] By adopting the above technical solution, the surface of the curled steel plate is protected, and the possibility of damage to the plate surface caused by friction between the electromagnet and the curled steel plate surface during movement is reduced, which is beneficial to ensuring the quality of the rolled plate.

[0020] Optionally, the lifting assembly is arranged in the middle of the mobile gantry.

[0021] The adoption of the above technical solution helps to ensure that the force is relatively balanced when the curled steel plate is lifted, thereby reducing the possibility of adverse effects caused by uneven force.

[0022] Optionally, the auxiliary discharging mechanism also includes a clamping assembly, which includes two groups of clamping parts symmetrically arranged at both ends of the moving gantry beam, and the clamping parts include a translation drive member, a lifting drive member and a clamping member. The lifting drive member is slidably connected to the moving gantry beam, the translation drive member is used to drive the lifting drive member to move axially along the moving gantry beam, and the clamping member is installed on the driving end of the lifting drive member.

[0023] By adopting the above technical solution, the clamping assembly is provided to supplement the lifting method of the lifting assembly, which can effectively avoid the curled plate from accidentally falling off and causing damage, and help ensure production safety.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. During the plate rolling operation, as the plate is rolled, the plate fixing assembly is adjusted to be temporarily connected to the rolled plate. Then, as the plate continues to roll, the lifting assembly is gradually adjusted to ensure that when the rolling is completed, the lifting assembly provides the main pulling force, so that the rolled steel plate can be smoothly and gently transferred to the discharging mechanism as the mobile gantry moves. This effectively avoids the phenomenon that the rolled steel plate falls heavily or even hits the discharging mechanism after the rolling is completed, which helps to extend the service life of the discharging mechanism.

[0026] 2. Through the cooperation of two sets of electromagnets, the curled steel plate can be temporarily fixed from both sides for adsorption and clamping, which helps to improve the temporary fixing effect. Moreover, before adsorbing to the curled steel plate, the two electromagnets can be adjusted to the same magnetic poles so that the two clamping arms can be opened to the maximum extent for easy clamping;

[0027] 3. The clamping assembly provided complements the lifting method using the lifting assembly, which can effectively prevent the curled sheet from accidentally falling off and causing damage, and helps to ensure production safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application embodiment discloses a plate rolling machine for steel plate processing. Figure 1 The plate rolling machine for steel plate processing includes a plate rolling body 1, a feeding mechanism 2 installed on the feeding side of the plate rolling body 1, a discharging mechanism 3 installed on the discharging side of the plate rolling body 1, and an auxiliary discharging mechanism 4. In this embodiment, the feeding mechanism 2 and the discharging mechanism 3 are both roller conveyor belts commonly used in the art.

[0034] Reference Figure 1 and Figure 2 The auxiliary discharging mechanism 4 includes a moving gantry 41 arranged on the discharging side of the plate rolling body 1 , a lifting assembly 42 installed on the moving gantry 41 , and a plate fixing assembly 43 arranged on the lifting assembly 42 .

[0035] Specifically, the mobile gantry 41 is installed across the discharging mechanism 3. In this embodiment, the mobile gantry 41 includes a gantry body 411 and a power member 413 that pushes the gantry body 411 to move along the discharging direction of the discharging mechanism 3. Slide blocks 412 are provided at the bottom ends of the two vertical beams of the gantry body 411. Slide grooves 31 are provided on the two side beams of the discharging mechanism 3 along the discharging direction of the discharging mechanism 3. The slide blocks 412 are slidably clamped in the slide grooves 31. The power member 413 acts on the slide blocks 412 and can drive the gantry body 411 to slide by driving the slide blocks 412. The power member 413 in this embodiment specifically includes a driving motor 4131 fixed to the end of the side beam of the discharging mechanism 3 on one side and a screw rod 4132 that is rotatably arranged in the slide groove 31 along the length direction of the slide groove 31. The screw rod 4132 is coaxially connected to the output shaft of the driving motor 4131, and the screw rod 4132 passes through the corresponding slide block 412 and is threadedly connected to the slide block 412. In this way, when the mobile gantry 41 needs to move, the drive motor 4131 is started, and the drive motor 4131 drives the screw rod 4132 to rotate, so that the slider 412 slides along the slide groove 31 under the limiting effect of the slide groove 31. In other embodiments, the power member 413 can also be set to two groups corresponding to the side beams of the discharge mechanism 3 to ensure that the two groups of power members 413 output synchronously. Of course, the power member 413 can also use a power output terminal such as a cylinder, a hydraulic cylinder, a linear motor, etc. that can drive the slider 412 to slide linearly.

[0036] Reference Figure 3 In this embodiment, the lifting assembly 42 specifically adopts a winch, which is fixed in the middle of the crossbeam of the gantry frame 411. The plate fixing assembly 43 includes two clamping arms 432 connected to the lifting chain of the lifting assembly 42. The upper ends of the two clamping arms 432 are hinged, and the lower ends are both equipped with electromagnets 431, and the electromagnets 431 on the two clamping arms 432 are arranged oppositely. The clamping ends of the two clamping arms 432 are both provided with electromagnets 431, and the two electromagnets 431 are arranged oppositely. In addition, a flexible cushion layer 4311 is adhered to the working surface of the electromagnet 431 for adsorbing the curled steel plate. In this embodiment, the flexible cushion layer 4311 specifically adopts a rubber layer to protect the surface of the curled plate. During the plate rolling operation, as the plate is curled, the two electromagnets 431 can be adjusted to be adsorbed to the two sides of the curled plate to achieve temporary fixation of the curled steel plate.

[0037] Furthermore, in order to avoid the problem of excessive opening of the clamping arms 432 when the two electromagnets 431 have the same magnetic poles, a limit member 433 is welded on one clamping arm 432, and the limit member 433 includes a connecting rod 4331 extending from one clamping arm 432 toward the other clamping arm 432, and a limit plate is horizontally provided at the end of the connecting rod 4331 extending toward the clamping arm 432, and a tension spring 434 is also connected between the two clamping arms 432 so that the two clamping arms 432 can cooperate and clamp.

[0038] Reference Figure 3 The auxiliary discharging mechanism 4 also includes a clamping assembly 44, which includes two sets of clamping parts symmetrically arranged at both ends of the cross beam of the mobile gantry 41. The clamping parts include a translation drive 441, a lifting drive 442 and a clamping member 443. The lifting drive 442 is slidably connected to the cross beam of the mobile gantry 41. The translation drive 441 is used to drive the lifting drive 442 to move axially along the cross beam of the mobile gantry 41. The clamping member 443 is installed on the driving end of the lifting drive 442. In this embodiment, the translation drive 441 and the lifting drive 442 are both hydraulic cylinders, and the clamping member 443 is a cross bar 4332. By setting the clamping assembly 44 to supplement the temporary fixing method of the auxiliary discharging mechanism 4, it can effectively avoid the occurrence of damage caused by accidental shedding of the curled sheet, which helps to ensure production safety.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
