Description

Technical Field

[0001] The utility model relates to the technical field of plate rolling machines, in particular to a plate rolling machine with a front limiting structure. Background Art

[0002] Plate rolling machine is an important processing equipment, mainly used to roll metal plates into cylindrical, arc-shaped or other shaped workpieces. It is a very important processing equipment. The plate rolling machine includes rollers, which apply local bending stress to the plate between the rollers to deform the plate locally, and roll along the entire length of the plate to bend and deform it. Under appropriate circumstances, the plate is bent several times.

[0003] The relationship between the interaction forces when the existing plate rolling machine rolls the plate, especially when processing hard plates, will cause the roller to rotate and rub against the two side brackets to cause wear. After a long time, the roller will deviate, affecting the rolling accuracy.

[0004] The existing patent (publication number: CN219188236U) discloses a plate rolling machine, which has a first side bracket and a second side bracket that play a supporting and limiting role, and also includes an adjustment part. The adjustment part can adjust the position relationship of multiple pressure rollers to increase the adjustability and plate rolling processing range. In addition, the plate rolling machine can fix the two side brackets and the fixed shaft through the new pressure roller structure, thereby reducing wear.

[0005] In response to the above problems, although the solution provided by the existing patent is capable of adjusting the position of the pressure roller to increase the processing range, when adjusting the pressure roller, adjustment mechanisms are respectively set at both ends of the pressure roller. It is necessary to adjust one mechanism first and then the other mechanism, and synchronous adjustment cannot be performed. As a result, after the pressure roller is adjusted, the levelness of the two ends is not uniform, resulting in poor plate processing effect. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A plate rolling machine with a front limit structure comprises a fixed frame 1, a pressure roller 2 is installed in the horizontal direction inside the fixed frame 1, both ends of the pressure roller 2 are connected with an adjustment mechanism for adjusting the plate rolling machine, and a driving mechanism for conveying the plate is provided on the right side of the fixed frame 1;

[0028] The adjusting mechanism comprises a mounting block 3, two mounting blocks 3 are provided, the two mounting blocks 3 are rotatably connected to the two ends of the pressure roller 2 through bearings, a screw rod 31 is threadedly connected in the vertical direction inside the two mounting blocks 3, a driven bevel gear 32 is fixed to the upper surface of the screw rod 31, an active bevel gear 33 is meshed with one side of the driven bevel gear 32, a fixing rod 34 is fixed inside the active bevel gear 33, a handle 35 is fixed to one end of the fixing rod 34, the outer surface of the mounting block 3 is slidably connected to a slide groove 38 opened on the inner wall of the fixing frame 1, the outer surface of the fixing rod 34 is sleeved with two fixed bearings 36, the outer surfaces of the two fixed bearings 36 are fixed with fixing plates 37 fixed to the fixing frame 1, and two fixed rollers 4 are installed at the lower end of the fixing frame 1 and close to the bottom of the pressure roller 2.

[0029] By adopting the above technical scheme, before using the plate rolling machine with a front limit structure, the fixing frame 1 is first placed in a suitable position. When the pressure roller 2 needs to be adjusted, the handle 35 can be manually turned to drive the fixing rod 34 to rotate. The fixing bearing 36 provided on the fixing plate 37 allows the fixing rod 34 to rotate more smoothly, so that the two active bevel teeth 33 respectively engage with the driven bevel teeth 32 to rotate, thereby driving the two screw rods 31 to rotate. When the screw rod 31 rotates, it drives the threaded mounting block 3 to move vertically, thereby adjusting the height of the pressure roller 2. The sliding groove 38 provided can guide the mounting block 3, thereby realizing the synchronous adjustment of the two ends of the pressure roller 2, which can effectively reduce the situation where the two ends of the pressure roller 2 are not level.

[0030] Specifically, Figure 1-Figure 4 As shown, the driving mechanism includes a driving motor 5, which is fixed to the right side of the fixing frame 1 by bolts. A driving gear 51 is fixed to the power output shaft of the driving motor 5. A transmission gear 52 is meshed on the outer surface of the driving gear 51. A transmission rod 53 is fixed to one end of the transmission gear 52. A limit bearing 54 embedded in the fixing frame 1 is sleeved on the outer surface of the transmission rod 53. A limit member 6 is installed on the left side of the fixing frame 1. Two fixing bolts 7 threadedly connected to the limit member 6 are installed on the outer surface of the fixing frame 1. The interior of the limit member 6 is rotatably connected to two guide rollers 8 through bearings.

[0031] By adopting the above technical solution, the workpiece to be processed is placed in the limit member 6, and the guide roller 8 in the limit member 6 can play a role of limit guidance, so that the plate is discharged through the limit member 6 and enters between the pressure roller 2 and the fixed roller 4. The set driving motor 5 drives the active gear 51 to engage the transmission gear 52 to rotate, thereby driving the transmission rod 53 to rotate, and the two transmission rods 53 synchronously drive the fixed roller 4 to rotate, so as to transport the plate. With the cooperation of the pressure roller 2, the plate is rolled. The set limit bearing 54 can ensure the stability of the fixed roller 4 during rotation. By unscrewing the fixing bolt 7, the fixation of the limit member 6 can be released, which is convenient for disassembly of the limit member 6.

[0032] Working principle: Place the workpiece to be processed into the limit member 6, which plays the role of limit guide, and the driving motor 5 drives the active gear 51 to engage the transmission gear 52 to rotate, and the two transmission rods 53 synchronously drive the fixed roller 4 to rotate, so as to convey the plate and roll the plate. By manually twisting the handle 35, the fixed rod 34 is driven to rotate, so that the two active bevel teeth 33 respectively engage the driven bevel teeth 32 to rotate, and then drive the two screw rods 31 to rotate. When the screw rod 31 rotates, it drives the threaded mounting block 3 to move vertically, so as to adjust the height of the pressure roller 2. The sliding groove 38 is set to guide the mounting block 3, so as to realize the synchronous adjustment of the two ends of the pressure roller 2, which can effectively reduce the situation where the two ends of the pressure roller 2 are not level.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
