Description

Technical Field

[0001] This utility model relates to the field of metal material manufacturing technology, specifically to a rolling device for manufacturing metal materials. Background Technology

[0002] Metal material manufacturing refers to the process of processing raw metal materials through various methods, including processing, forming, welding, and surface treatment, to produce parts or finished products of various shapes and sizes. Among these, rolling equipment is used to manufacture metal materials into plate or sheet structures, and is generally a rolling mill.

[0003] Existing calenders mainly consist of a frame, control system, transmission system, heating and cooling system, and multiple adjustable-pitch pressure rollers. They utilize two or more pressure rollers to press molten or semi-solid materials, causing the material to expand and form thin sheets or plates of specific thickness and width. Therefore, they have the following shortcomings in use:

[0004] 1. Metal rolling requires high extrusion pressure, and the pressure rollers are prone to bending and deformation under high pressure, resulting in a "thick in the middle and thin at both sides" phenomenon in thin metal sheets, which affects the quality of finished products;

[0005] 2. The rolled thin metal sheet is prone to warping and deformation after cooling. Utility Model Content

[0006] I. Technical problems to be solved

[0007] The technical problem this invention aims to solve is that pressure rollers are prone to bending deformation with continuous use, and the rolled thin metal sheets are prone to warping and deformation.

[0008] II. Technical Solution

[0009] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a rolling device for manufacturing metal materials, including an operating table, a through groove in the middle of the operating table, a lower pressure roller below the through groove, and a corresponding upper pressure roller above the through groove;

[0010] One end of the lower pressure roller is connected to a motor, and an electric telescopic rod is connected between the motor and the operating table. The upper end of the lower pressure roller can extend above the through groove. There are two upper pressure rollers, which are composed of a plum blossom-shaped rotating roller and multiple sleeve rollers that fit around the rotating roller. One end of the rotating roller is connected to a second motor, and a connecting plate is provided between the other ends of the two second motors. The other end of the connecting plate is connected to a drive shaft, and the other end of the drive shaft is equipped with a third motor. The side wall of the operating table is provided with a support plate that fits around the drive shaft. The front side of the support plate is provided with a strip groove that cooperates with the drive shaft and allows the drive shaft to slide up and down. An electric telescopic rod is connected between the support plate and the third motor.

[0011] A pressure plate is provided on one side of the through groove above the operating table. An inverted U-shaped support plate II is provided at the upper end of the pressure plate and is connected to the operating table. An electric telescopic rod III is connected between the support plate II and the pressure plate.

[0012] As an improvement, the other end of the lower pressure roller is connected to a rotating rod, and a support frame is rotatably sleeved on the rotating rod. The support frame is connected to the operating table via the same electric telescopic rod.

[0013] As an improvement, the other end of the rotating roller is connected to a rotating rod two with a diameter smaller than that of the rotating roller. The rotating rod two located below is fitted with a support frame two. The lower end of the support frame two is connected to an electric telescopic rod four located on the operating table.

[0014] As an improvement, the operating platform corresponding to the lower part of the electric telescopic rod four is provided with a front-to-back groove. A screw is provided between the front and back inner walls of the groove. One end of the screw extends out of the operating platform and is connected to the motor four. The lower end of the electric telescopic rod four is connected to a moving block that fits into the groove and is threaded onto the outside of the screw, so that the support frame two can be disengaged from the rotating rod two.

[0015] As an improvement, the lower corner of the pressure plate is rounded.

[0016] As an improvement, a pressure sensor is provided on the side of the lower end of the pressure plate near the through groove, and a pressure plate is provided on the other side.

[0017] III. Beneficial Effects

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] 1. The upper pressure roller of this utility model adopts a plum blossom-shaped rotating roller combined with a multi-set sleeve roller structure. The modular design can distribute the extrusion pressure of metal rolling to multiple sleeve rollers, avoiding bending deformation of a single pressure roller due to excessive local pressure. At the same time, the upper pressure roller can be rotated and replaced, and can be adjusted in time when a single sleeve roller is deformed, ensuring the stability of rolling during the rolling process and guaranteeing the quality of the finished product.

[0020] 2. This utility model uses a pressure plate set on one side of the operating table through the slot, which can move up and down through an electric telescopic rod connected to the support plate 2. It can perform secondary pressing and shaping on the rolled metal sheet, reducing its warping or deformation. The pressure sensor at the lower end of the pressure plate can monitor the pressing force in real time, monitor the rolling effect of the material, and rework it in time. Then, it is pressed again by the pressing plate to enhance the shaping effect. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] As attached Figures 1-6 As shown, a rolling apparatus for manufacturing metal materials includes an operating table 1. The operating table 1 has a through groove 2 in the middle. A lower pressure roller 3 is provided below the through groove 2, and a corresponding upper pressure roller 4 is provided above it. One end of the lower pressure roller 3 is connected to a motor 5. An electric telescopic rod 6 is connected between the motor 5 and the operating table 1. The electric telescopic rod 6 drives the lower pressure roller 3 to move up and down, and the motor 5 drives the lower pressure roller 3 to rotate. The upper end of the lower pressure roller 3 can extend above the through groove 2.

[0030] Furthermore, the other end of the lower pressure roller 3 is connected to a rotating rod 19, and a support frame 20 is rotatably sleeved on the rotating rod 19. The support frame 20 is connected to the operating table 1 through the same electric telescopic rod 6 to form a "double-sided symmetrical support" structure, which avoids the problem of uneven pressure on the pressure roller and shaking during operation caused by traditional single-sided support, and further improves the stability of the calendering process.

[0031] The upper pressure roller 4 consists of two rollers, each composed of a plum blossom-shaped rotating roller and multiple sleeve rollers fitted around it. The modular design distributes the extrusion pressure of metal rolling to multiple sleeve rollers, preventing a single pressure roller from bending and deforming due to excessive local pressure. One end of the rotating roller is connected to a motor 7, and a connecting plate 8 is provided between the other ends of the two motors 7. The other end of the connecting plate 8 is connected to a drive shaft 9, and the other end of the drive shaft 9 is equipped with a motor 10. The side wall of the operating table 1 is provided with a support plate 11 fitted around the drive shaft 9. The front side of the support plate 11 is provided with a strip groove 12 that cooperates with the drive shaft 9 and allows the drive shaft 9 to slide up and down. An electric telescopic rod 13 is connected between the support plate 11 and the motor 10. The electric telescopic rod 13 can drive the upper pressure roller 4 to move up and down, adjusting the distance between the upper pressure roller 4 and the lower pressure roller 3. The motor 7 can drive the upper pressure roller 4 to rotate, cooperating with the lower pressure roller 3 to roll the metal material into different thicknesses.

[0032] When a single roller deforms during use, the two upper pressure rollers 4 can be driven to rotate around it by the motor 310, so that the two upper pressure rollers 4 can rotate and be replaced, so that the calendering can continue and the stability of calendering can be maintained during the calendering process, ensuring the quality of the finished product. Moreover, the upper pressure roller 4 after use can be removed and the deformed upper pressure roller 4 can be replaced separately, which greatly shortens the maintenance time and maintenance cost.

[0033] Furthermore, the other end of the rotating roller is connected to a rotating rod 21 with a diameter smaller than that of the rotating roller. The rotating rod 21 located below is fitted with a support frame 22. The lower end of the support frame 22 is connected to an electric telescopic rod 23 located on the operating table 1, which provides additional stable support for the upper pressure roller 4 and adjusts its height up and down with the upper pressure roller 4. The operating table 1 below the electric telescopic rod 23 is provided with a front-to-back groove 24. A screw 25 is provided between the front and back inner walls of the groove 24. One end of the screw 25 extends out of the operating table 1 and is connected to a motor 26. The lower end of the electric telescopic rod 23 is connected to a moving block 27 that fits into the groove 24 and is threaded onto the outside of the screw 25. When replacing the upper pressure roller 4, the support frame 22 is first driven to move away from the rotating rod 21 before replacement.

[0034] A pressure plate 14 is provided on one side of the through groove 2 above the operating table 1. The upper end of the pressure plate 14 is provided with an inverted U-shaped support plate 15 connected to the operating table 1. An electric telescopic rod 16 is connected between the support plate 15 and the pressure plate 14. The distance between the pressure plate 14 and the operating table 1 is controlled by the electric telescopic rod 16. It is matched with the metal sheet and can perform secondary pressing and shaping on the metal sheet after rolling to reduce its warping or deformation.

[0035] Furthermore, a pressure sensor 17 is provided on the side of the lower end of the pressure plate 14 near the through groove 2, and a pressure plate 18 is provided on the other side. The pressure force can be monitored in real time, the rolling effect of the material can be monitored, and rework can be carried out in time. The material can then be pressed again by the pressure plate 18 to enhance the shaping effect. The lower corner of the pressure plate 14 is rounded, so that the metal sheet can enter the pressure plate 14 more smoothly.
