Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, specifically a CNC four-roll plate rolling machine. Background Technology

[0002] A plate rolling machine is a processing device that bends metal sheets into desired circular, arc, or conical shapes. It operates on the principle of three points forming a circle, achieving the predetermined shape by adjusting the relative positions of the side rollers and the top roller. Currently, four-roll plate rolling machines are widely used due to their advantages, including wide versatility, minimal residual straight edges, automatic plate positioning, and the ability to complete the rolling process in a single loading operation.

[0003] However, traditional four-roll plate rolling machines still have shortcomings when rolling large-diameter cylinders or high-strength plates. For example, during the plate rolling process, the plate is prone to lateral displacement or local wrinkles due to radial pressure and axial tension. Especially when rolling cylinders with large curvature radii, the edges of the plate, which lack dynamic support, are prone to deformation due to stress concentration, resulting in poor cylinder roundness error. This necessitates multiple rework corrections, leading to low efficiency.

[0004] Therefore, we propose a CNC four-roll plate rolling machine to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] The purpose of this utility model is to provide a CNC four-roll plate rolling machine to solve the problems currently found in the market as mentioned in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the present invention provides the following technical solution: a CNC four-roll plate rolling machine, comprising a machine body, wherein a four-roll rolling assembly is mounted on the machine body, and an auxiliary support mechanism is provided on both the front and rear sides of the four-roll rolling assembly, and the auxiliary support mechanism is mounted on the machine body;

[0009] The auxiliary support mechanism includes a conveying support component mounted on the machine body, a bracket support component mounted on the conveying support component, a hydraulic cylinder mounted between the machine body and the conveying support component, and an adjusting component mounted between the conveying support component and the bracket support component.

[0010] Furthermore, the conveying support includes a rotating shaft that is rotatably mounted on the machine body, with support plates fixed at both ends of the rotating shaft, and a plurality of conveying rollers rotatably mounted between the two support plates.

[0011] The above technical solution enables the conveying rollers on the support plate to convey the plate material.

[0012] Furthermore, the bracket support includes a rotating plate rotatably mounted on the support plate, and a plurality of support rollers are rotatably mounted between the left and right rotating plates.

[0013] The above technical solution enables the support rollers to rotate on the turntable.

[0014] Furthermore, both ends of the first hydraulic cylinder are rotatably connected to the machine body and the support plate, and the connecting shaft between the first hydraulic cylinder and the support plate is eccentrically set with respect to the rotating shaft.

[0015] The above technical solution enables the support plate to rotate on the machine body once the hydraulic cylinder is started.

[0016] Furthermore, the adjusting component includes a second hydraulic cylinder fixed to the support plate, the output end of the second hydraulic cylinder being rotatably connected to a connecting rod, and the other end of the connecting rod being rotatably mounted on the side of the rotating plate.

[0017] The above technical solution enables the rotating plate to rotate on the support plate when the second hydraulic cylinder is started.

[0018] Furthermore, the connecting shaft between the connecting rod and the support plate is not on the same straight line as the connecting shaft between the support plates.

[0019] The above technical solution enables a tilting angle to be formed between several support rollers and several conveying rollers, so as to provide lateral support for the plate.

[0020] 3. Beneficial effects:

[0021] Compared with the prior art, the CNC four-roll plate rolling machine of this utility model, by adopting the technical solution provided by this utility model, conveys the plate material before rolling through conveying support components and bracket support components, and can provide lateral support for the plate material during rolling to bear the lateral force of the plate material, thus solving the problem of easy deformation and improving the rolling accuracy. The specific details are as follows:

[0022] (1) Start hydraulic cylinder one. Hydraulic cylinder one drives the support plate to swing around the rotating shaft through the eccentric connecting shaft. When hydraulic cylinder one retracts, the support plate descends, so that the conveying roller is placed horizontally, so that the material plate can be conveyed into the four roller pressing assembly to achieve supply. When hydraulic cylinder one extends, the support plate swings upward around the connecting shaft, driving the conveying roller to rise and lift the plate.

[0023] ( ) Start hydraulic cylinder two. Hydraulic cylinder two drives the rotating plate to rotate around the support plate through the connecting rod. When hydraulic cylinder two extends, it drives several support rollers to rotate to a state that is relatively horizontal with several conveying rollers, so as to facilitate the straight conveying of the plate. When hydraulic cylinder two retracts, the connecting rod pushes the rotating plate to tilt to one side, so that several support rollers and several conveying rollers form an inclination angle. With the assistance of the extension of hydraulic cylinder one, it drives the support rollers to provide side support for the rolled plate, bear the lateral force of the plate, solve the problem of easy deformation when rolling large diameter cylinders, improve the rolling accuracy, and the support rollers and conveying rollers are in rolling contact with the surface of the plate, with low friction, which can reduce the risk of scratches on the surface of the plate, and at the same time reduce the wear of moving parts of the equipment and extend the service life.

[0034] Please see Figure 1-5 A CNC four-roll plate bending machine includes a machine body 1, on which a four-roll rolling assembly 2 is mounted. A set of auxiliary support mechanisms 3 is provided on both the front and rear sides of the four-roll rolling assembly 2, and the auxiliary support mechanisms 3 are mounted on the machine body 1. Each auxiliary support mechanism 3 includes a conveying support member 31 mounted on the machine body 1, a bracket support member 32 mounted on the conveying support member 31, a hydraulic cylinder 33 installed between the machine body 1 and the conveying support member 31, and an adjusting member 34 installed between the conveying support member 31 and the bracket support member 32. The conveying support member 31 includes... The system includes a rotating shaft 311 rotatably mounted on the machine body 1, with support plates 312 fixed at both ends of the rotating shaft 311, and several conveying rollers 313 rotatably mounted between the two support plates 312; the bracket support 32 includes a rotating plate 321 rotatably mounted on the support plate 312, and several support rollers 322 rotatably mounted between the left and right rotating plates 321; both ends of the hydraulic cylinder 33 are rotatably connected to the machine body 1 and the support plate 312, and the connecting shaft between the hydraulic cylinder 33 and the support plate 312 is eccentrically set with respect to the rotating shaft 311;

[0035] After hydraulic cylinder 33 is started, hydraulic cylinder 33 drives support plate 312 to swing around shaft 311 through eccentric connecting shaft. When hydraulic cylinder 33 retracts, support plate 312 descends, so that conveying roller 313 is placed laterally, so that material sheet is conveyed into four roller pressing assembly 2 to achieve supply. When hydraulic cylinder 33 extends, support plate 312 swings upward around connecting shaft, driving conveying roller 313 to rise and lift the sheet.

[0036] The adjusting component 34 includes a second hydraulic cylinder 341 fixed on the support plate 312. The output end of the second hydraulic cylinder 341 is rotatably connected to a connecting rod 342, and the other end of the connecting rod 342 is rotatably mounted on the side of the rotating plate 321. The connecting shaft between the connecting rod 342 and the support plate 312 is not on the same straight line as the connecting shaft between the support plate 312 and the support plate 312.

[0037] Hydraulic cylinder 341 is activated, driving the rotating plate 321 to rotate around the connecting shaft between the rotating plate 321 and the support plate 312 via connecting rod 342. When hydraulic cylinder 341 extends, it drives several support rollers 322 to rotate to a state relatively horizontal with several conveying rollers 313, facilitating the straight conveying of the sheet metal. When hydraulic cylinder 341 retracts, connecting rod 342 pushes the rotating plate 321 to tilt to one side, creating an inclination angle between the support rollers 322 and the conveying rollers 313. With the assistance of the extension of hydraulic cylinder 33, the support rollers 322 provide lateral support to the rolled sheet metal, bearing the lateral force of the sheet metal. This solves the problem of easy deformation when rolling large-diameter cylinders, improves rolling accuracy, and since both the support rollers 322 and the conveying rollers 313 have rolling contact with the sheet metal surface, the friction is low, reducing the risk of scratches on the sheet metal surface and reducing wear on moving parts of the equipment, thus extending its service life.

[0038] Working principle: When using this CNC four-roll plate bending machine, if... Figure 1-5 As shown, firstly, hydraulic cylinder 33 is activated, and support plate 312 descends, causing conveyor roller 313 to be placed laterally. Simultaneously, hydraulic cylinder 341 is activated, driving several support rollers 322 to rotate to a state relatively horizontal with the several conveyor rollers 313. Under the action of the several support rollers 322 and several conveyor rollers 313, the sheet material is easily conveyed into the four-roller winding assembly 2 for supply. During the winding process, hydraulic cylinders 33 and 341 are activated in the reverse direction, driving support rollers 322 to provide lateral support to the rolled sheet material, bearing the lateral force of the sheet material, solving the problem of easy deformation when rolling large-diameter cylinders, and improving the winding accuracy.
