Description

Technical Field

[0001] This utility model relates to sheet metal rolling, and in particular to a shaping tooling for sheet metal rolling. Background Technology

[0002] Sheet metal rolling involves rolling a flat sheet metal into a cylindrical shape using a plate rolling machine, and then welding the two edges together. Due to its own springback after rolling, the sheet metal doesn't form a perfectly cylindrical shape, and the two edges will have some gaps. Therefore, before welding, the sheet metal is usually shaped to ensure it forms a complete cylindrical shape and the edges are not glued together. The shaped fixture typically includes: a frame, a lower die block detachable from the frame, a mounting plate that moves vertically relative to the frame, a hydraulic cylinder that moves the mounting plate, and an upper die block detachable from the mounting plate. The rolled sheet metal is placed in the lower semicircular groove of the lower die block. The hydraulic cylinder moves the upper die block downwards, and the upper semicircular groove of the upper die block mates with the lower semicircular groove of the lower die block to shape the sheet metal. The upper and lower die blocks of the shaped fixture are replaced accordingly depending on the diameter of the rolled cylinder. When changing a set of dies, it is crucial that the axes of the upper and lower semicircular grooves are aligned vertically. With existing fixed tooling, adjusting the relative positions of the upper and lower mold blocks when changing a set of molds is a cumbersome and inconvenient operation. Utility Model Content

[0037] Please see Figure 1 and Figure 2 A shaping fixture for sheet metal rolling includes an equipment frame 1, a mounting plate 2, a hydraulic cylinder 3, an upper mold block 4, a lower mold block 5, and an adjustment part 6.

[0038] Please see Figure 2 , Figure 3 and Figure 6 The equipment frame 1 is rectangular in shape. More specifically, it can be composed of an upper horizontal part 1-1, a lower horizontal part 1-2, and two vertical parts 1-3, which are welded together. The top surface of the lower horizontal part 1-2 has two first grooves 1a and one second groove 1b. Both the first grooves 1a and the second groove 1b are along the width direction, and the second groove 1b is located between the two first grooves 1a.

[0039] Mounting plate 2 is slidably connected to the upper horizontal part 1-1 of equipment frame 1. More specifically, two optical axes 2a can be fixedly connected to the top surface of mounting plate 2 as guide rods, and linear bearings of matching optical axes 2a are fixedly connected to the corresponding positions of the upper horizontal part 1-1.

[0040] The hydraulic cylinder 3 is used to move the mounting plate 2. More specifically, the cylinder body of the hydraulic cylinder 3 is fixedly connected to the upper horizontal part 1-1, and the piston rod extends downward through the upper horizontal part 1-1 and is connected to the mounting plate 2.

[0041] The upper mold block 4 is detachably connected to the mounting plate 2. More specifically, the two can be fixedly connected using bolts. The bottom surface of the upper mold block 4 has an upper semi-circular groove, meaning there can be multiple upper mold blocks 4 with different sizes of upper semi-circular grooves. The appropriate upper mold block 4 is selected and installed on the mounting plate 2 according to the outer diameter of the roll to be shaped.

[0042] Please see Figure 2 and Figure 3 Fasteners 7 are provided between the lower mold block 5 and the two first grooves 1a. The fasteners 7 are used to achieve a detachable connection between the lower mold block 5 and the equipment frame 1. More specifically, connecting blocks 5a are fixed at each of the four corners of the lower mold block 5. Each connecting block 5a has a waist-shaped groove through which bolts pass. The cross-section of the first groove 1a is convex, and the nut is located in the wider portion of the first groove 1a and is restricted from rotation. The bolt passes through the connecting block 5a and is threaded onto the nut. Tightening the bolts fixes the lower mold block 5 to the equipment frame 1; loosening the bolts allows the lower mold block 5 to move out along its width.

[0043] The top surface of the lower mold block 5 has a lower semi-circular groove, meaning there can be multiple lower mold blocks 5 with different sizes of lower semi-circular grooves, each corresponding to an upper mold block 4 to form multiple sets of molds. A suitable lower mold block 5 is selected and installed on the equipment frame 1 according to the outer diameter of the roll to be shaped. The bottom surface of the lower mold block 5 has a limiting groove 5b along its long side.

[0044] Please see Figure 4 The adjustment part 6 is located in the second slot 1b and includes two limit blocks 6a and an adjustment mechanism 6b.

[0045] Please see Figure 5 Two limiting blocks 6a are partially located within the second groove 1b and partially extend beyond the second groove 1b and are located within the limiting groove 5b. An adjusting mechanism 6b is used to adjust the distance between the two limiting blocks 6a. More specifically, the adjusting mechanism 6b can use a bidirectional lead screw. Mounting blocks are fixedly connected to both ends of the second groove 1b, and the end of the bidirectional lead screw is rotatably connected to the mounting block via a bearing seat. Two lead screw nuts fitted on the bidirectional lead screw are respectively fixedly connected to the portions of the two limiting blocks 6a within the second groove 1b.

[0046] Adjust the distance between the two limit blocks 6a so that the two limit blocks 6a can switch between the following two states: the installation and removal state in which the lower mold block 5 can not be restricted from moving upward, and the adjustment state in which the lower mold block 5 can only move along the length direction.

[0047] When changing a mold, it is crucial that the axes of the upper and lower semicircular grooves are aligned vertically. The changeover process is briefly described below:

[0048] S1. The hydraulic cylinder 3 moves the original upper mold block 4 down to touch the original lower mold block 5, and removes the original upper mold block 4 from the mounting plate 2.

[0049] S2, Hydraulic cylinder 3 moves mounting plate 2 upward and resets it, hoisting and removing the original upper mold block 4;

[0050] S3. Loosen the bolts, move the nut down to the appropriate position, lift the original lower mold block 5, separate the original lower mold block 5 from the limit block 6a in the installation and disassembly state, move the original lower mold block 5 along the width, and remove the original lower mold block 5 with the fastener 7 from the equipment frame 1.

[0051] S4. Hoist the new upper mold block 4 into the equipment frame 1. The hydraulic cylinder 3 moves the mounting plate 2 down and installs the new upper mold block 4 onto the mounting plate 2.

[0052] S5. Hoist the new lower mold block 5 with fastener 7, adjust the position of the nut, and as the new lower mold block 5 enters the equipment frame 1, the nut enters the wider part of the first groove 1a; move the new lower mold block 5 down to fit the top surface of the lower horizontal part 1-2, and switch the two limit blocks 6a from the installation and removal state to the adjustment state, and place the new lower mold block 5 on the lower horizontal part 1-2.

[0053] S6. Adjust the new lower mold block 5 along the long side (adjustment can be done by tapping with a rubber hammer) to align the axis of the upper semicircular groove with the axis of the lower semicircular groove, and fix the lower mold block 5 to the equipment frame 1 with fasteners 7.

[0054] Please see Figure 6 and Figure 7 In some embodiments, the inner sides of the two vertical portions 1-3 of the equipment frame 1 are provided with a top support 1c and a screw 1d for moving the top support 1c in the width direction. More specifically, the two vertical portions 1-3 of the equipment frame 1 are fixedly connected with nuts for threaded connection of the screw 1d.

[0055] In this way, by rotating the screw 1d, the top support 1c abuts against the lower mold block 5, and moves the lower mold block 5 along the long side, the operation of the above step S6 can be more convenient and precise.

[0056] Please see Figure 5 In some embodiments, the cross-section of the limiting groove 5b is an inverted trapezoid, that is, the two limiting blocks 6a have mating inclined surfaces.

[0057] Please see Figure 8 and Figure 9In some embodiments, for the connecting blocks 5a at the four corners of the lower mold block 5, the connecting block 5a includes a lower block 5a-2 and an upper block 5a-1. Accordingly, the lower block 5a-2 has a first waist-shaped groove 5a-11, and the upper block 5a-1 has a second waist-shaped groove 5a-21. The lower block 5a-2 is fixed to the lower mold block 5, and bolts can enter / exit along the width direction. More specifically, the first waist-shaped groove 5a-11 is not closed. The upper block 5a-1 is inserted into the lower block 5a-2, and bolts can only enter / exit the upper block 5a-1 along the vertical direction. More specifically, the second waist-shaped groove 5a-21 is closed, and the bottom surface of the upper block 5a-1 has a ring of protrusions 5a-22 along the second waist-shaped groove 5a-21, the protrusions 5a-22 being used to insert into the first waist-shaped groove 5a-11.

[0058] Thus, in step S5 above, the hoisting of the new lower mold block 5 can be performed without the fastener 7 and the upper connecting block 5a. After step S5 is completed, the bolt is inserted into the second waist-shaped groove 5a-21 of the upper block 5a-1; the position of the nut is adjusted so that the nut enters the wider part of the first groove 1a; the upper block 5a-1 and the fastener 7 are moved along the width direction to directly above the lower block 5a-2, while the bolt enters the lower block 5a-2; the upper block 5a-1 and the fastener 7 are moved down so that the protrusion 5a-22 of the upper block 5a-1 is inserted into the first waist-shaped groove 5a-11.

[0059] Please see Figure 5 In some embodiments, the two arc edges of the upper and lower semicircular grooves are chamfered and connected to a protective layer 8, such as a rubber layer. The protective layer 8 is used to protect the outer wall of the roll sheet from being scratched by the arc edges.

[0060] Please see Figure 1 and Figure 6 In some embodiments, the outer sides of the two vertical portions 1-3 of the equipment rack 1 each have a plurality of storage compartments 1e. The storage compartments 1e are used to place tools required for operation.
