Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a curling device for storage tank production. Background Art

[0002] Storage tanks are a common type of container, usually made of metal materials such as iron, aluminum, stainless steel, etc., used to store and transport various items such as food, liquids, chemicals, etc. The sealing of the storage tank uses the flange of the tank body and the round edge of the tank cover to roll and seal in the sealing machine, so that the tank body and the tank cover are rolled together and pressed to form a tight overlapping structure.

[0003] During the early stage of the tank body production, the edge of the metal part to be curled is squeezed by the curling wheel, forcing the edge of the metal part to be curled to be folded, and finally forming the curling of the tank body.

[0004] Most of the existing curling equipment uses a slot to limit one end of the can body, but during the curling process of the other end cooperating with the curling wheel, the curling wheel rolls on the end, causing the can body to shake due to uneven force, thereby affecting the subsequent curling effect.

[0005] Therefore, it is necessary to provide a crimping device for storage tank production to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a curling device for storage tank production, which solves the problem of poor curling effect caused by uneven force on the tank body.

[0009] A cylinder is fixedly installed on the end of the adaptation platform away from the base, and an outer cylinder is fixedly installed on the end of the cylinder away from the adaptation platform. A plurality of support plates are installed on the outer side of the outer cylinder, and the plurality of support plates are arranged circumferentially; a plurality of support plates are hinged with straight connecting rods on the inner sides close to the outer cylinder, and the ends of the straight connecting rods away from the support plates are hinged to the outer cylinder; a plurality of support plates are hinged with corner connecting rods on the inner sides close to the outer cylinder, and the ends of the corner connecting rods away from the support plates are hinged to the outer cylinder; the corner connecting rods are located on the side of the straight connecting rods away from the adaptation platform; thus, the can body is installed on the adaptation platform, and the straight connecting rods and the corner connecting rods make the support plates close to the inner wall of the can body, thereby achieving stability of the can body, reducing the probability of shaking when the can body is curled in the later stage, and further ensuring the curling effect.

[0010] Furthermore, the support plate is an arc plate; thus, the arc plate-shaped support plate can better fit the inner wall of the can body.

[0011] Furthermore, a piston rod is installed inside the cylinder through a dynamic seal, one end of the piston rod extends out from the end of the cylinder away from the adapter table, and the side of the piston rod is clearance-matched with the outer cylinder; a pull rod is hinged at the corner of the corner connecting rod, and the end of the pull rod away from the corner connecting rod is hinged to the outside of the piston rod; thus, the cylinder controls the piston rod to move up and down, driving the pull rod to move, and the pull rod controls the corner connecting rod to rotate, and then the corner connecting rod cooperates with the straight connecting rod to pull the corresponding support plate to retract and extend; thereby, multiple support plates can provide internal support for can bodies of different diameters.

[0012] Furthermore, the arc surface of the support plate is in an I-shape; thus, the I-shaped support plate can resist shear force and also bear part of the bending moment.

[0013] Furthermore, the arc surface of the support plate is provided with a plurality of right oblique bars and a plurality of left oblique bars, and the plurality of right oblique bars and left oblique bars are arranged alternately and do not contact each other; the right oblique bars and the left oblique bars are in an eight-shaped shape; the lengths of the right oblique bars and the left oblique bars are adjusted according to the shape of the support plate; thereby, the right oblique bars and the left oblique bars increase the friction between the support plate and the can body; the right oblique bars and the left oblique bars in an eight-shaped shape can resist the torque transmitted by the can body, thereby enhancing the holding effect of the support plate on the can body.

[0014] Furthermore, a support base is fixedly installed on the top of the body, a rotating motor is fixedly installed on the top of the support base, a rotating rod is fixedly installed on the output end of the rotating motor, the end of the rotating rod away from the rotating motor passes through the support base, and a double-headed plate is fixedly installed on the end; the double-headed plate is located directly above the adaptation platform, and a wheel seat is movably installed on the end of the double-headed plate away from the rotating motor, and a curling wheel is pivotally connected to the end of the wheel seat away from the double-headed plate; thus, the rotating motor controls the rotation of the double-headed plate through the rotating rod, and the double-headed plate controls the two wheel seats to rotate synchronously, so that the corresponding curling wheel performs circumferential motion at the end of the can body; the screw moving mechanism controls the can body to move up, and the side surface of the curling wheel performs an extrusion motion with the edge of the can body end, forcing the edge to fold.

[0015] Furthermore, two slide grooves are provided at one end of the double-headed plate away from the rotating motor, and the two slide grooves are symmetrically arranged; the slide grooves are located at the end of the double-headed plate, and the radial direction of the slide grooves is parallel to the side length of the double-headed plate; the inner wall of the slide grooves is installed with the wheel seat through a sliding connection; thus, the two wheel seats slide relative to each other at the corresponding slide grooves to achieve distance adjustment between the two wheel seats so as to adapt to can bodies of different diameters.
