Description

Technical Field

[0001] This utility model relates to the field of rolling equipment technology, and in particular to a simplified three-roll plate rolling machine. Background Technology

[0002] A plate rolling machine is a device that bends sheet metal into cylinders. Taking a common three-roll plate rolling machine as an example, the upper roller moves vertically up and down symmetrically in the center of the two lower rollers. The metal sheet is clamped between the upper and lower rollers. With the help of the downward pressure of the upper roller and the rotation of the lower roller, the metal sheet undergoes multiple continuous bending processes, resulting in permanent plastic deformation and being rolled into the desired cylinder.

[0003] The left end of the upper roller is rotatably connected to the left support seat, and the right end of the upper roller is rotatably connected to the right support seat through the tipping mechanism. Before forming, the upper roller is rotatably connected to the tipping mechanism. After forming, the upper roller is disconnected from the tipping mechanism, and the cylinder is removed from the right end of the upper roller.

Detailed Implementation

[0030] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 This utility model embodiment provides a simplified tilting three-roll plate rolling machine, including a base plate 10, a left support plate 20, a right support plate 30, a left lifting block 40, a right lifting block 50, an upper roller 60, a lower roller 70, and a tilting mechanism 80. The left support plate 20 and the right support plate 30 are fixed on the base plate 10. The left lifting block 40 is disposed on the left support plate 20, and the right lifting block 50 is disposed on the right support plate 30. The left end of the lower roller 70 is rotatably connected to the left support plate 20, and the right end of the lower roller 70 is rotatably connected to the right support plate 30. The left end of the upper roller 60 is rotatably connected to the left lifting block 40. The tilting mechanism 80 includes a second rotating shaft 81, a shaft seat 82, a clamping plate 83, and a support member 84. The right end of the upper roller 60 is rotatably connected to the left lifting block 40. The second rotating shaft 81 is coaxially connected to the first rotating shaft 81. A shaft seat 82 is sleeved on the second rotating shaft 81. A locking plate 83 is provided with a locking hole. The bottom wall of the locking hole has a first bottom surface and a second bottom surface. The first bottom surface and the second bottom surface are not coplanar. The locking plate 83 is set on the right lifting block 50. The locking plate 83 rotates counterclockwise relative to the right lifting block 50. The shaft seat 82 enters the locking hole. The first bottom surface does not contact the lower surface of the shaft seat 82, and the second bottom surface contacts the lower surface of the shaft seat 82. A support member 84 is movably inserted into the locking hole. The upper surface of the support member 84 contacts the top wall of the locking hole, and the lower surface of the support member 84 contacts the upper surface of the shaft seat 82. The locking plate 83 rotates clockwise relative to the right lifting block 50. The locking plate 83 disengages from the shaft seat 82.

[0032] For example, the left support plate 20 and the right support plate 30 are welded to the base plate 10, the left support plate 20 and the right support plate 30 are parallel to each other, the upper roller 60 and the two lower rollers 70 are arranged in a triangular layout, which is no different from the conventional design, the transmission structures of the upper roller 60 and the lower rollers 70 adopt conventional designs, the left lifting block 40 and the right lifting block 50 move up and down synchronously, and the synchronous transmission structure adopts a conventional design.

[0033] For example, both ends of the lower roller 70 are rotatably connected to the left support plate 20 and the right support plate 30 through the shaft connecting members 90, and the left end of the upper roller 60 is rotatably connected to the left lifting block 40 through the shaft connecting member 90, see Figure 9 , the shaft connecting member 90 includes a shaft sleeve 91, a first rotating shaft 92, and a pin shaft 93. The left end of the upper roller 60 and both ends of the lower roller 70 are coaxially and integrally connected with the first rotating shaft 92. The left lifting block 40, the left support plate 20 and the right support plate 30 are internally provided with a copper shaft sleeve 91, the first rotating shaft 92 is nested into the shaft sleeve 91, the left lifting block 40, the left support plate 20 or the right support plate 30 is provided with a first pin hole, the shaft sleeve 91 is provided with a second pin hole, and the pin shaft 93 sequentially penetrates through the first pin hole and the second pin hole to fix the shaft sleeve 91 relative to the left lifting block 40, the left support plate 20 or the right support plate 30, which can protect the left lifting block 40, the left support plate 20 or the right support plate 30 from abrasion. The contact area between the first rotating shaft 92 and the shaft sleeve 91 is large, so the pressure of the rotating shaft on the shaft sleeve 91 is relatively small, which is suitable for heavy-duty plate rolling machines.

[0034] For example, the longitudinal section of the shaft seat 82 is rectangular, the longitudinal section of the clamping hole is rectangular, the distance between the two side surfaces of the clamping hole is equal to the width of the shaft seat 82, the first bottom surface and the second bottom surface of the clamping hole are stepped, the interface between the first bottom surface and the second bottom surface is located on the center line of the clamping hole, the distance from the rotating shaft of the clamping plate 83 and the right lifting block 50 to the edge of the first bottom surface is equal to the distance from the rotating shaft of the clamping plate 83 and the right lifting block 50 to the lower surface of the shaft seat 82, and the distance from the rotating shaft of the clamping plate 83 and the right lifting block 50 to the second bottom surface is equal to the distance from the rotating shaft of the clamping plate 83 and the right lifting block 50 to the lower surface of the shaft seat 82.

[0035] For example, the supporting member 84 is rod-shaped, third pin holes are provided on both sides of the clamping plate 83, a pin groove is provided on the upper surface of the shaft seat 82, the supporting member 84 penetrates through the third pin holes and enters the pin groove to prevent the upper roller 60 from horizontally swinging, and the longitudinal section of the pin groove is semicircular.

[0036] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0037] (1) By rotating the clamping plate 83 counterclockwise in a single direction and inserting the supporting member 84, the upper roller 60 is rotatably connected with the clamping plate 83. By rotating the clamping plate 83 clockwise in a single direction and removing the supporting member 84, the upper roller 60 is disconnected from the clamping plate 83, so the structure is relatively simplified.

[0038] (2) The design of the first and second bottom surfaces of the bottom wall of the card hole is such that the right end of the upper roller 60 is biased downward towards the lower roller 70, and the card plate 83 cannot be inserted into the upper roller 60, which can check the parallelism between the upper roller 60 and the lower roller 70.

[0039] Furthermore, the tipping mechanism 80 includes a tipping cylinder, the fixed end of which is connected to the right lifting block 50, and the telescopic end of which is connected to the clamping plate 83.

[0040] See Figure 5 , Figure 6 Furthermore, the card plate 83 is provided with a "U" shaped groove, the two sides of the "U" shaped groove are rotatably connected to the right lifting block 50, and the top surface of the "U" shaped groove is in contact with the top surface of the right lifting block 50.

[0041] For example, see Figure 6 The top surface and side surface of the right lifting block 50 are machined into an inclined plane. The distance from the rotating shaft of the clamping plate 83 to the top surface of the right lifting block 50 is greater than the distance from the rotating shaft of the clamping plate 83 to the side surface of the right lifting block 50. The distance from the rotating shaft of the clamping plate 83 to the inclined plane of the right lifting block 50 is less than the distance from the rotating shaft of the clamping plate 83 to the side surface of the right lifting block 50. The distance from the rotating shaft of the clamping plate 83 to the top surface of the right lifting block 50 is equal to the distance from the rotating shaft of the clamping plate 83 to the top surface of the "U"-shaped groove. The top surface of the "U"-shaped groove is in contact with the top surface of the right lifting block 50, resulting in strong load-bearing capacity.

[0042] In one embodiment, see Figure 7 , Figure 8 A roller 85 is fixed between the two sides of the "U"-shaped groove. A straight groove is provided on the right lifting block 50, and the roller 85 can move linearly along the groove. Under the action of the tilting cylinder, the clamping plate 83 first rotates relative to the right lifting block 50, and then moves horizontally linearly along the right lifting block 50. The shape of the clamping hole matches the shape of the bearing seat 82, and the clamping plate 83 and the bearing seat 82 are seamlessly connected, which can be achieved with only one cylinder. The top wall of the clamping hole is also provided with a pin groove. The support member 84 passes through the third pin hole and enters the pin groove combination with a longitudinal section of a complete circle formed by the pin groove of the top wall of the clamping hole and the pin groove of the upper surface of the bearing seat 82, so as to prevent the clamping plate 83 from horizontally disengaging from the bearing seat 82.

[0043] See Figure 1 , Figure 4 Furthermore, the simplified three-roll plate rolling machine includes a balancing mechanism 100, which includes an extension roller 101. One end of the extension roller 101 is coaxially and integrally connected to the left end of the upper roller 60, and the other end of the extension roller 101 is a cantilever end.

[0044] See Figure 1 , Figure 4Furthermore, the balancing mechanism 100 includes a balancing frame 102 and a lead screw 103. The balancing frame 102 is fixed on the base plate 10, and the lead screw 103 is threadedly connected to the balancing frame 102.

[0045] Rotate the lead screw 103, and the lead screw 103 moves downward in a straight line relative to the balance frame 102, and contacts the cantilever end of the extension roller 101.

[0046] See Figure 1 , Figure 4 Furthermore, the lower end face of the lead screw 103 is an arc-shaped curved surface.

[0047] See Figure 1 , Figure 4 Furthermore, the balancing mechanism 100 includes a handwheel 104, which is located at the upper end of the lead screw 103.

[0048] See Figure 1 , Figure 4 Furthermore, the balancing mechanism 100 includes a guide block 105, and the balancing frame 102 includes a fixing plate 1021 and a guide rod 1022. The guide block 105 is threadedly connected to the lead screw 103, and the side of the guide block 105 is provided with a guide groove for engaging the guide rod 1022.

[0049] See Figure 1 , Figure 4 Furthermore, a guide rod 1022 is provided on each side of the fixing plate 1021, and a guide groove is provided on each side of the corresponding guide block 105.

[0050] See Figure 1 , Figure 4 Furthermore, the guide groove is U-shaped.

[0051] See Figure 1 , Figure 2 In one embodiment, the annular wall of the upper roller 60 is provided with a spiral texture to generate axial thrust on the plate. The plate, the upper roller 60, and the lower roller 70 interact with each other. The upper roller 60 and the lower roller 70 always remain close to the side of the left support plate 20 or the right support plate 30 to prevent "roller slippage".
