[0004] The above-mentioned technology has the following disadvantages: in the process of edge rolling, the distance between edge rolling wheel and tank body is not easy to control, so that the pressure applied to tank body is not easy to control, and thus the success rate of tank body edge rolling is high. UTILITY MODEL CONTENTS

[0005] The utility model solves the technical problem of designing a new type of tank body edge rolling tool, which is simple in design and can improve the success rate of tank body edge rolling.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme: a kind of tank body edge rolling tool, including chuck and the conversion flange connected with one end of chuck, the other end of chuck is movably connected with card grab, card grab can move radially along the radius of chuck, the card grab is at least two, each card grab is fixedly connected with one tool body outside, and all tool bodies are enclosed into a circle, each tool body includes connecting portion and extension portion, and the height of extension portion is greater than that of connecting portion, recess is arranged between connecting portion and extension portion.

[0007] Further, the edge of the chuck is fixedly connected with a baffle, the bottom of the baffle is fixed on the periphery of the card grab stroke, and the outside of the baffle extends beyond the edge of the chuck.

[0008] Further, the number of the baffles is four, and the four baffles are evenly distributed on the chuck.

[0009] Further, the number of the clamps is three, and the three clamps are evenly distributed on the chuck.

[0010] Further, the connection between the clamp and the tool body is provided with a reinforcing rib, and the reinforcing rib is arranged on both sides of each clamp.

[0017] In order to strengthen the understanding of the utility model, the utility model will be described in detail below in combination with the embodiments and the drawings, and the embodiments are only used to explain the utility model, and do not constitute a limitation on the protection scope of the utility model.

[0018] As Figs. 1 to 3 shown is a kind of tank body's edge rolling tool, specifically including chuck 2 and the conversion flange 1 connected with one end of chuck, wherein the other end of conversion flange 1 is connected with driving device, to drive the rotation of chuck, here is prior art, will not repeat.

[0019] The other end of the chuck 2 is movably connected with the clamping claws 3, which can move radially along the radius of the chuck 2. The chuck and the clamping claws can be manually, hydraulically, pneumatically or electrically driven, which are all prior arts and not the improvements of the present application, and thus will not be described in detail.

[0020] The clamping claws 3 are at least two, and each clamping claw 3 is fixedly connected with a tool body 4. All the tool bodies 4 can be arranged in a circle, but the tool bodies 4 are not connected with each other. The radius of the circle formed by the tool bodies 4 is different when the clamping claws 3 are contracted or expanded, but the overall shape is a circle, which leads to that the tool bodies 4 have a certain curvature as a whole, and the curvature of the tool bodies 4 is different when the number of the clamping claws 3 is different.

[0021] The clamping claws 3 are preferably three, and thus the tool bodies 4 are also three, as shown in Fig. 2 Of course, the clamping claws 3 can also be two or more, and the number is not limited as long as it is greater than or equal to two, because the clamping claws 3 do not have the function of clamping the can body.

[0022] As shown in Fig. 1 Each tool body 4 includes a connecting portion 41 connected with the clamping claw 3 and an extension portion 42 extending therefrom. The height of the extension portion 42 is greater than that of the connecting portion 41 when viewed from the side, so that there is a groove 43 between the connecting portion 41 and the extension portion 42. The groove 43 is arranged to match the outer rollers, Fig. 1 The dashed line in the figure is the outer roller.

[0023] In use, the clamping claws 3 are contracted, the extension portions 42 extend into the can body, the clamping claws 3 are expanded, and the tool bodies 4 exert an outward expansion force on the can body. When the can body reaches the required deformation, the outer rollers start to roll the edges of the can body at the position of the groove 43.

[0024] The expanded distance of the clamping claws 3 is controlled to be 80-250 mm, which can be accurately controlled, so that the expansion force of the tool bodies on the can body of different diameters can be accurately controlled by the expanded distance of the clamping claws, and the outer rollers only have the function of rolling the edges and do not exert pressure or only exert a small and fixed pressure, which does not affect the success rate of the rolling edges.

[0025] In order to better fix the can body, the edge portion of the contact surface between the chuck 2 and the clamping claws 3 is fixedly connected with a baffle 5. The bottom of the baffle 5 is fixed on the periphery of the stroke of the clamping claws 3 and does not affect the movement of the clamping claws 3. The outer side of the baffle 5 extends beyond the edge of the chuck 2. The baffle 5 can block the can body and prevent the displacement of the can body. The number of the baffles 5 can be four, and the four baffles are uniformly distributed on the chuck. Of course, the number of the baffles 5 can also be more, and the number is not limited as long as the effect is achieved.

[0026] Since the contact area of the clamping claws 3 with the tool body 4 is relatively small, in order to make the connection of the clamping claws 3 with the tool body 4 more firm, as shown in Fig. 3 the reinforcing ribs 6 are welded at the connection of the clamping claws 3 with the tool body 4, and the reinforcing ribs 6 are arranged on both sides of each clamping claw 3.

[0027] In the present application, since the external force for deforming the can body is arranged inside the can body, and the moving distance of the clamping claws is easy to control, the accurate deformation and rolling of the can body can be realized, and finally the success rate of the can body rolling can be higher.

[0028] The embodiments of the present application disclose the preferred embodiments, but are not limited to this, and the ordinary skilled in the art can easily understand the spirit of the present application according to the above embodiments, and make different inferences and changes, as long as they do not deviate from the spirit of the present application, they are within the protection scope of the present application.
