Description

Technical Field

[0001] This utility model relates to a plate rolling machine, and more particularly to a plate conveying frame for a plate rolling machine. Background Technology

[0002] A plate rolling machine is used to roll flat sheet metal into a cylindrical shape. Because the sheet metal is relatively long and heavy, a plate conveyor frame is generally used to hold it. The plate conveyor frame typically includes a frame, at least two pairs of bearing seats mounted on the frame, and guide rollers of the same number of bearing seats mounted on one pair of bearing seats. The guide rollers support the sheet metal and push it into the rolling rollers of the plate rolling machine. The diameter of the rolled cylinder is adjustable on the plate rolling machine, and the height of the rolled cylinder is determined by using sheet metal of a corresponding width. When the height of the rolled cylinder changes, a different width of sheet metal is required. Currently, the guide rollers of existing plate conveyor frames are generally of fixed length and cannot well adapt to sheet metal of different widths. Utility Model Content

[0029] Please see Figure 1 A plate conveying frame for a plate rolling machine includes an equipment frame 1, a linear drive unit 2, at least two pairs of bearing seats 3, and two sets of linear guide rollers 4.

[0030] The equipment rack 1 includes a base 1-1 and two frames 1-2 connected to the base 1-1. More specifically, the base 1-1 can be rectangular and can be composed of four square tubes connected together; the frames 1-2 can be U-shaped.

[0031] The linear drive unit 2 is used to adjust the distance between the two shelves 1-2. That is, at least one of the two shelves 1-2 is movable relative to the base 1-1, and the linear drive unit 2 is disposed between the base 1-1 and the shelf 1-2 that is movable relative to the base 1-1.

[0032] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the first linear drive includes two sets of synchronous belts 2-1 and a motor 2-2.

[0033] Both sets of synchronous belts 2-1 are installed on the base 1-1, respectively located within two rectangular tubes on the horizontal side of the base 1-1. The bottom of the first frame 1-2 is fixedly connected to the upper part of the two sets of synchronous belts 2-1, and the bottom of the other frame 1-2 is fixedly connected to the lower part of the two sets of synchronous belts 2-1. That is to say, both frames 1-2 are movable relative to the base 1-1; the parameters of the two sets of synchronous belts 2-1 are the same, and the two synchronous pulleys of each set of synchronous belts 2-1 are also the same, making the upper and lower parts of the synchronous belts 2-1 horizontal.

[0034] Motor 2-2 is used to drive two sets of synchronous belts 2-1 to move together. More specifically, the synchronous pulleys on the first side of the two sets of synchronous belts 2-1 can be fixedly connected to the same rotating shaft 2a, which is located inside one of the longitudinal rectangular tubes of the base 1-1. Motor 2-2 can be mounted on the outer wall of the rectangular tube, and its output shaft extends into the rectangular tube and is driven through a set of bevel gears 2b and the rotating shaft 2a.

[0035] Motor 2-2 drives two sets of synchronous belts 2-1 to move together, and the two frames 1-2 move in opposite directions at the same speed, adjusting the distance between the two frames 1-2.

[0036] Please see Figure 2 , Figure 5 , Figure 6 In some embodiments, the base 1-1 includes a base plate 1-1-1 and a shell 1-1-2. That is, each of the four rectangular tubes is composed of an upper U-shaped portion and a lower plate. The four U-shaped portions are fixedly connected to form the shell 1-1-2, and the four plates are fixedly connected to form the base plate 1-1-1.

[0037] Both sets of synchronous belts 2-1 are installed on the base plate 1-1-1.

[0038] The frame 1-2 includes two connecting parts 1-2-1 and a frame body 1-2-2. The connecting parts 1-2-1 are slidably connected to the base plate 1-1-1. More specifically, a linear guide rail 1b can be provided between the connecting parts 1-2-1 and the base plate 1-1-1 to achieve a sliding connection. The connecting parts 1-2-1 are also used for fixed connection with the timing belt 2-1. More specifically, the connecting parts 1-2-1 can be U-shaped, with the timing belt 2-1 located in the recess of the connecting parts 1-2-1. The upper and lower parts of the timing belt 2-1 are both fixedly connected to mounting blocks 2c, which are fixedly connected to the connecting parts 1-2-1. The frame 1-2-2 is detachably connected to the two connecting parts 1-2-1. More specifically, the housing 1-1-2 has a strip-shaped groove 1a through which the connecting parts 1-2-1 pass and move. The frame 1-2-2 is U-shaped, with its bottom fitted into the through-parts of the two connecting parts 1-2-1, and can be detachably and fixedly connected to the through-parts of the two connecting parts 1-2-1 by fasteners.

[0039] The assembly of the base 1-1, frame 1-2, and first linear drive mechanism is simpler and more convenient. More specifically, firstly, the four connecting parts 1-2-1 are slidably installed on the base plate 1-1-1; then, the two sets of synchronous belts 2-1 are installed on the base plate 1-1-1; next, the synchronous belts 2-1 are connected to the corresponding two connecting parts 1-2-1; then, the motor 2-2 is installed on the housing 1-1-2; then, the housing 1-1-2 is connected to the base plate 1-1-1, and the bevel gear 2b of the motor 2-2 meshes with the bevel gear 2b of the rotating shaft 2a; finally, the frame 1-2-2 is fixedly installed on the corresponding two connecting parts 1-2-1.

[0040] Please see Figure 1 Each pair of bearing housings 3 is installed on two frames 1-2 respectively.

[0041] Please see Figure 1 and Figure 2 A set of guide rollers 4 is mounted on a pair of bearing seats 3. That is, the number of guide roller sets 4 is the same as the number of bearing seats 3. A set of guide rollers 4 includes a connecting shaft 4-1, a middle roller body 4-2, and two end roller bodies 4-3. The middle roller body 4-2 is fixedly connected to the middle position of the connecting shaft 4-1. The two end roller bodies 4-3 are rotatably connected to the two bearing seats 3 respectively, and are also respectively sleeved on both sides of the connecting shaft 4-1. Each end roller body 4-3 is provided with a first limiting member 4a that restricts its axial movement relative to the connecting shaft 4-1. More specifically, each end roller body 4-3 may have a threaded hole that connects to a sleeve hole for sleeved connection to the connecting shaft 4-1, and the first limiting member 4a is a bolt threaded into the threaded hole.

[0042] After the sheet material is placed on the guide roller assembly 4, it is supported by two end rollers 4-3 and a middle roller 4-2. The restriction of the two first limiting members 4a on the two end rollers 4-3 can be released, and the distance between the two frames 1-2 can be changed by the linear drive unit 2, causing relative axial movement between the end rollers 4-3 and the connecting shaft 4-1. This changes the distance between the two end rollers 4-3 to accommodate sheet materials of different widths. Furthermore, connecting shafts 4-1 of different lengths can be replaced to change the adjustment range of the distance between the two end rollers 4-3.

[0043] Please see Figure 4 In some embodiments, both end rollers 4-3 have annular stops 4e. The annular stops 4e are used to block the edges of the sheet material, limiting the axial displacement of the sheet material along the guide roller assembly 4.

[0044] Please see Figure 3 and Figure 4 In some embodiments, the fixed connection between the middle roller 4-2 and the connecting shaft 4-1 is removable. More specifically, referring to the first limiting member 4a, a bolt is provided on the middle roller 4-2 as a second limiting member 4b. Tightening the second limiting member 4b fixes the middle roller 4-2 to the connecting shaft 4-1, and loosening the second limiting member 4b releases the fixed connection. In the state where the middle roller 4-2 and the connecting shaft 4-1 are unfixed, at least one end roller 4-3 allows the connecting shaft 4-1 to be inserted into / removed from the end near the bearing seat 3. More specifically, the sleeve hole of the end roller 4-3 is a through hole. In the state where the middle roller 4-2 and the connecting shaft 4-1 are unfixed, at least one end roller 4-3 can restrict the radial movement of the middle roller 4-2. More specifically, the end faces of the end roller 4-3 and the middle roller 4-2 that are close to each other have matching annular protrusions 4c and annular grooves 4d, respectively.

[0045] When it is necessary to replace the connecting shaft 4-1 with one of different lengths, the operation is simpler. Release the two first limiting pieces 4a from the two end rollers 4-3; reduce the distance between the two end rollers 4-3 so that the annular protrusion 4c and the annular groove 4d can be inserted and fitted; release the fixed connection between the middle roller 4-2 and the connecting shaft 4-1; pull the connecting shaft 4-1 out from the end roller 4-3 near the bearing seat 3, and insert the new connecting shaft 4-1 from the end roller 4-3 near the bearing seat 3.

[0046] Please see Figure 7In some embodiments, the number of guide roller groups 4 is three, and the two pairs of bearing seats 3 corresponding to the two groups of side guide rails can be adjusted in the vertical direction to a fixed position on the frame 1-2. More specifically, two vertical optical shafts 3a are fixedly provided at the bottom of the bearing seat 3, and the frame 1-2 is fixedly connected to a linear bearing matching the optical shafts 3a, so that the bearing seat 3 can move up and down relative to the frame 1-2; the frame 1-2 is also fixedly connected to a lead screw nut, and the lead screw nut is threadedly connected to a lead screw 3b.

[0047] During normal sheet material conveying, the bearing seats 3 are in contact with the top surface of the frame 1-2, and the three pairs of bearing seats 3 are at the same height. Rotating the lead screw 3b causes the top of the lead screw 3b to abut against the bearing seats 3, allowing it to move upward. After raising the two pairs of bearing seats 3 on both sides, the three sets of guide rollers 4 can be used to place the sheet material rolled into a cylinder.
