Description

Technical Field

[0001] The utility model relates to a cone rolling device and belongs to the technical field of mechanical processing. Background Art

[0002] The three-cone plate rolling machine is a device that rolls metal sheets into cones. It is widely used in boilers, shipbuilding, petroleum, chemical industry, metallurgy, metal structure and other machinery manufacturing industries. At present, there are some problems in the layout of the three cones of the three-cone plate rolling machine. Two cones of the three-cone plate rolling machine are on the outside of the rolled cone barrel and one is on the inside of the rolled cone barrel. One of the generatrix of the inner cone barrel will coincide with one of the generatrix of the inner cone of the rolled cone barrel, resulting in poor fitting of the three cone barrels with the rolled cone barrel. The plate is easy to slide when being rolled, and the movement speed ratio of the large and small arcs of the fan-shaped plate when driven by the cone barrel is different. The rolled steel plate often moves to the large diameter end of the roller due to uneven force, and rubs against the machine body after contact, resulting in varying degrees of damage to the machine body and the plate.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] A cone rolling device, such as Figure 1-2 As shown, it includes a machine body 1, on which are provided two rotatable first cone rollers 2 and a rotatable second cone roller 3, the first cone roller 2 being connected to a motor; the two first cone rollers 2 are symmetrically arranged along the left and right sides, and the second cone roller 3 is liftable and arranged above between the first cone rollers 2; the first cone roller 2 and the second cone roller 3 are arranged on the front side of the machine body 1, and a guiding device 4 is also provided on the front end surface of the machine body 1.

[0023] Among them, the two first cone rollers 2 are active rollers, and the two lower rollers are rotated by the motor drive, and the upper roller is the second cone roller 3, and the second cone roller 3 moves up and down at the central symmetrical position of the two first cone rollers 2. Specifically, the plate is placed between the two first cone rollers 2 and the second cone roller 3, and the second cone roller 3 moves downward to press the plate. The two first cone rollers 2 rotate to drive the plate to move, while ensuring that the pressing amount of the second cone roller 3 remains unchanged, so that each generatrix of the workpiece has the same curvature and becomes a cone. In addition, when the plate moves toward the side of the machine body 1 during the rolling process, since a guide device 4 is provided on the front side of the machine body 1, the plate does not contact the machine body 1, but directly contacts the guide device 4 while driving the plate to move to both sides, thereby preventing friction between the plate and the machine body 1. When the rear ends of the first tapered roller 2 and the second tapered roller 3 are close to the front end surface of the machine body 1, the guiding device 4 is located at the rear ends of the first tapered roller 2 and the second tapered roller 3; when there is a gap between the rear ends of the first tapered roller 2 and the second tapered roller 3 and the front end surface of the machine body 1, the guiding device 4 is located behind the first tapered roller 2 and the second tapered roller 3.

[0024] As another specific embodiment, the guide device 4 is located outside the gap between the first cone roller 2 and the second cone roller 3, and inside the axis of the first cone roller 2. During the rolling process, the sheet is located in the gap between the first cone roller 2 and the second cone roller 3, and moves along the gap toward the machine body 1. Therefore, the guide device 4 is located in the gap between the first cone roller 2 and the second cone roller 3 to correspond to the upper and lower positions of the sheet, and does not conflict with the first cone roller 2 and the second cone roller 3. Moreover, the guide device 4 is located inside the axis of the first cone roller 2 to ensure that even if the sheet has just been rolled out from the gap to both sides, it can be guided after contacting with the guide device 4.

[0025] As another specific embodiment, the guide device 4 includes two guide devices 4, which are symmetrically arranged on the left and right sides of the second tapered roller 3. The two symmetrically arranged guide devices 4 can ensure that both sides of the plate will not rub against the machine body 1 during the back and forth rolling process.

[0026] As another specific embodiment, the guide device 4 includes a rotatable guide rod 41, the axial direction of the guide rod 41 is along the up-down direction, and the guide rod 41 is arranged on the front end surface of the machine body 1 through a connecting piece. Specifically, when the plate is offset, the side of the plate first contacts the guide rod 41 and then slides to both sides. At this time, since the guide rod 41 can rotate left and right, it cooperates with the moving direction of the plate, and can change the sliding contact into rolling, which greatly reduces friction and reduces damage to the plate.

[0027] As another specific embodiment, the lower end of the guide rod 41 is lower than the upper edge of the first cone roller 2. Since the two sides of the plate move outward along the upper edge of the first cone roller 2 during the rolling process, the lower end of the guide rod 41 is lower than the upper edge of the first cone roller 2, which can ensure that the guide rod 41 can be connected to the plate without the plate moving out of the gap between the guide rod 41 and the first cone roller 2.

[0028] As another specific embodiment, the connecting member is a bearing seat 42. The bearing seat 42 provides a stable support structure for the bearing and fixes it to the front end surface of the machine body 1, ensuring that the bearing runs in the correct position.

[0029] As another specific embodiment, a limiting portion is provided above the guide rod 41, and the limiting portion is located above the top bearing seat 42. The limiting portion enables the upper end of the guide rod 41 to contact the top of the bearing seat 42, thereby limiting the axial position of the guide rod 41 to prevent the guide rod 41 from sliding downward. Furthermore, the limiting portion can be integrally provided with the guide rod 41, or can be detachably provided.

[0030] As another specific implementation, the connecting member includes two, and the two connecting members are arranged along the axial direction of the guide rod 41. Specifically, the two connecting members are both bearing seats 42, which can provide more stable support, reduce the bending and deviation of the guide rod 41, and improve the rotation accuracy and operation stability.

[0031] As another specific implementation, the two connecting members are respectively arranged at the upper part and the middle part of the guide rod 41. Since the lower end of the guide rod 41 contacts the plate, the lower end is a free end and is not connected to the bearing seat 42 to prevent interference.

[0032] As another specific embodiment, it also includes a support seat 5, which is arranged at the front lower part of the first tapered roller 2. The support seat 5 can ensure that the first tapered roller 2 remains stable during operation and will not shift or rotate due to a large force, thereby ensuring processing accuracy. In addition, during the operation of the plate rolling machine, a large force needs to be applied to the metal sheet to bend it. The support seat 5 can help disperse this force to prevent the first tapered roller 2 from being damaged due to excessive force.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention is extended to any new features or any new combination disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.

[0034] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
