Description

Technical Field

[0001] The invention relates to the technical field of rounding rolling equipment, in particular to special equipment for rounding forming of oil tanks. Background Art

[0002] When sheet metal, such as aluminum plate and steel plate, is bent and rounded, an arc-shaped track is usually used to guide the sheet metal plate for guided rounding. When rounding the oil tank barrel, the outside needs to be pressed with an annular groove after rounding to facilitate the subsequent mechanical positioning and handling. In the process of rounding the sheet metal, due to the pulling guidance, both sides will have different degrees of scraping deformation due to the asynchronous movement of the two sides, resulting in excessive pulling due to friction, which makes it difficult to weld after rounding and inconvenient for lateral groove positioning. In addition, the overall round surface cannot directly locate the end-to-end diameter length on the formed closed circle guide, which has certain limitations.

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0036] In one embodiment of the present invention: Please refer to the attached Figure 1 , 3 -5, comprising two groups of outer drums 1, inner drums 2 and inner rollers 3, the edge of the outer drum 1 and the two end margins of the inner drum 2 are fixed to each other, the side of the outer drum 1 is provided with an opening group, the opening group is used to rotate and open the guide oil tank plate, the outer wall of the inner drum 2 is fitted and fixed inside the outer drum 1, the inside of the inner drum 2 is provided with an embedded guide rail 201, the gear on the embedded guide rail 201 is meshed with a clamping assembly, and one side of the clamping assembly is provided with a clamping plate 206 for fixing one end of the oil tank plate;

[0037] The two groups of outer rollers 1 and inner rollers 2 have the same structure and are arranged opposite to each other. The two clamping components are intermittently and alternately driven. A plurality of inner diameter adjustment components 104 are provided on the outer roller 1. The adjustment end of the inner diameter adjustment component 104 is connected to a winding arc plate 112. The telescopic stroke of the winding arc plate 112 is located between the circular ring formed by the circular diameter gap between the inner rolling circle 3 and the inner roller 2.

[0038] Please refer to Figure 3-5 The clamping assembly includes an L-shaped fixing plate, the embedded guide rail 201 is arranged in the inner wall of the inner drum 2, a connecting plate 202 is arranged on one side of the L-shaped fixing plate, the connecting plate 202 is bent from the side of the embedded guide rail 201 and extends into the embedded guide rail 201 for sliding connection, an annular internal gear belt 205 is arranged on the inner wall of the inner drum 2, a driving gear 204 is arranged on the L-shaped fixing plate, and the driving gear 204 is meshed with the internal gear belt 205 for transmission;

[0039] A movable pile 207 is provided on the side of the L-shaped fixed plate, the clamping plate 206 is connected to the outside of the movable pile 207, a center connecting pile 208 is provided at the center point of the movable pile 207, a hinge 210 is movably connected to the center connecting pile 208, a movable connecting pile 209 is provided on the clamping plate 206, the other end of the hinge 210 is rotatably connected to the movable connecting pile 209, and the clamping plate 206 includes two parallel clamping plates for fixing the oil tank plate;

[0040] The driving gears 204 on both sides move alternately, and the single movement diameter distance of the driving gear 204 on one side is twice the difference between the movement diameters of the driving gears 204 on both sides.

[0041] The present invention adopts bilateral non-synchronous alternating intermittent action, so that the friction travel generated by the two sides of the plate in a single guiding process is small, so that it cannot form excessive pulling action, greatly reducing the generation of side friction, improving the rounding effect, facilitating the alignment of the two ends and reducing the difficulty of welding after rounding;

[0042] The bilateral linkage method is as follows: the oil tank lateral circular plate (hereinafter referred to as the circular plate) is introduced from the external rotating seat 101 of the outer drum 1 through a conveyor belt, and the locking groove 103 is opened and closed, so that the rotating arc plate 102 is downwardly introduced into the entire circular plate. The layout range of the rotating arc plate 102 can be in the middle position of the outer locking blocks of the two inner drums 2. After one side of the circular plate is guided to the clamping space of the inner drum 2 through the rotating arc plate 102, the gripper part of the inner drum 2, that is, the clamping plate 206 part, is manually fixed to one end of the circular plate extending into the outer drum 1, and the fixed positions at both ends are close to the circular plate margin. During the locking period, the distance between the two sets of outer rollers 1 and inner rollers 2 is appropriately adjusted to determine the width of the circular plate (i.e., the height of the oil drum). After the fixing is completed, the driving gears 204 on both sides are started respectively, so that the driving gears 204 are meshed with the inner gear belt 205 to drive one side of the circular plate to rotate. The winding space is located between the outer roller 1 and the circular diameter section of the inner roller 3. The circular margin of the guide circle is the same as the axis of the inner gear belt 205 but the circular diameter is different. The alternating action can set a certain motion trajectory distance at a time. When the driving gear 204 on one side is driven, the other side does not move, and the circular plate is rotated. The body is offset in a small range within the interval of the inner roller 2. When one side rotates, the rotation distance is twice the circular distance between the two sides. At this time, the alternating motion is performed, and the driving gears 204 on both sides always maintain a certain range of cross distances. The motion structures on both sides are set to the outer roller 1 and inner roller 2 structures on the A side and the B side, that is, the margins of the circular plates connected at the same position on both sides, the driving gear 204 on the A side rotates one circle on the inner gear belt 205, and the driving gear 204 on the B side rotates two circles on the inner gear belt 205, forming a rolling circle diameter difference, and then the driving gear 204 on the A side rotates alternately. The moving gear 204 rotates two circles on the inner gear belt 205, and then drives the driving gear 204 on the B side to rotate two circles on the inner gear belt 205 to form an alternating pulling and guiding. At this time, each pulling brings a certain offset of the tail of the circular plate. First, the tail is offset to the outer side of the outer drum 1 and does not enter the rotating arc plate 102, so there will be no collision or scratching. The part of the other end that enters the rotating arc plate 102 can have at least a gap due to the protruding part of the clamping plate 206 on the side, and the inner surface is in contact with the winding arc plate 112, and the cooperation and adaptation will not affect the rounding effect of the circular plate.

[0043] refer to Figure 5The present invention places the clamping plate 206 at the movable end of the movable pile 207 by setting a movable center connection pile 208, an movable connection pile 209 and a hinge 210, so that the clamping part of the clamping plate can be passively moved adaptively, which has two beneficial effects. First, when the end of the clamping plate 206 is movable, when the driving gear 204 on one side rolls forward, a corresponding pull is generated on the clamping plate 206 fixed on the other side. The end of the movable clamping plate 206 can be adaptively biased by rotating the axial position, which prevents the clamping from loosening and reduces the left and right lateral movement of the non-fixed section; second, when one side crosses the other side for meshing and driving, if the side of the circular plate has hard friction, the conductive force can also passively adapt to the rotation angle through one end of the movable clamping plate 206, thereby preventing accidents and improving the fault tolerance of the device, which is convenient for automated production;

[0044] The L side of the L-shaped fixed plate is an installation platform extending toward the axis of the inner drum 2. The embedded guide rail 201 is an inner rail on the fastener part on the margin of the inner wall of the inner drum 2. A connecting plate 202 is arranged on the side of the L-plate close to the inner wall of the inner drum 2 to extend into the embedded guide rail 201 for guiding movement, which can support the L-shaped fixed plate and enable the driving gear 204 to always maintain an engagement state with the external positioning block 105.

[0045] Please pay attention to Figure 1-3 The outer cylindrical wall of the outer drum 1 has a rotating seat 101 and a locking groove 103. The rotating seat 101 is connected with a rotating arc plate 102. The rotating distal end of the rotating arc plate 102 is electrically locked with the locking groove 103. The rotating arc plate 102 is used to guide the conveyor belt into the oil tank plate.

[0046] Please pay attention to Figure 2 A plurality of fixing blocks 4 are fixed to the sides of the outer drum 1 and the inner drum 2, and two ends of a single fixing block 4 are fixed to the outer drum 1 and the inner drum 2 respectively.

[0047] In yet another embodiment of the present invention:

[0048] Please pay attention to Figure 1-3 , a plurality of inner diameter adjustment components 104 are evenly spaced and fixed on the outer circumference of one end of the outer drum 1, the inner diameter adjustment component 104 comprises an external positioning block 105 arranged outside the outer drum 1, one side of the external positioning block 105 is provided with a convex plate 106, one side of the convex plate 106 is provided with a track plate 109 pointing to the center of the outer drum 1, and the other end of the track plate 109 is fixed to the inner roller 3;

[0049] A cylinder 107 is provided on one side of the convex plate 106, and a driving end of the cylinder 107 penetrates the convex plate 106 and is provided with a push rod 108 pointing to the center of the outer drum 1, and one end of the connecting plate 110 is slidably connected to the winding arc plate 112;

[0050] A connecting plate 110 is provided on one side of the ejection rod 108 and is connected to an inner movable plate 111. A plurality of inner grooves 113 are provided inside the winding arc plate 112. The inner movable plate 111 is movably connected to the inner grooves 113. A single inner groove 113 corresponds to a single set of inner diameter adjustment components 104.

[0051] The winding arc plate 112 is a winding plate material, one end of which is provided with an oblique cutout 115, and the other end is provided with a connecting adaptation plate 114. The interior of the inner rolling circle 3 is provided with a torsion spring type tightening pile, and the torsion spring type tightening pile is connected to one end of the connecting adaptation plate 114.

[0052] The adjustment method of the inner diameter adjustment component 104 is roughly as follows: by starting the cylinder 107 to drive toward one side of the axis of the outer roller 1 and the inner roller 3, the multi-directional cylinder 107 is driven synchronously, and the inner movable plate 111 generates an inward extrusion force on the winding arc plate 112. The inner movable plate 111 moves inside the inner groove 113, so that the winding arc plate 112 is wound inwardly, thereby reducing the maximum radius of the outer circle of the winding arc plate 112, thereby increasing or decreasing the difference between the inner diameter circle of the inner roller 2 and the outer diameter circle of the winding arc plate 112, so as to adapt to the winding requirements of circular plates of corresponding thickness.
