Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment, specifically to a self-positioning quick-assembly steel plate flatbed machine. Background Technology

[0002] Steel plate flattening machines are mainly used for straightening, cutting, and punching galvanized metal sheets. They play an important role in the manufacturing industry and are widely used in shipbuilding, automobile manufacturing, machinery manufacturing, construction, and other fields. With the development of Industry 4.0 and intelligent manufacturing, steel plate flattening machines have been further improved in terms of automation and intelligence. By adopting CNC systems and sensor technology, automated production is achieved, improving production efficiency and product quality.

[0003] Chinese patent CN118663729A discloses a flatbed straightening machine for stainless steel coils. Through the design of a limiting plate, a rotating shaft, and a rotary motor, the stainless steel coil to be processed is first installed on a placement rack. Then, the rotary motor is controlled via the operation panel to drive the rotating shaft, thereby adjusting the position of the limiting plate. Adjustment is complete when the limiting plate contacts the placement rack, thus limiting the stainless steel coil on the rack and preventing it from shifting position due to rotation during processing, and also preventing it from falling off. The design of an infrared detector allows the machine to measure the length of the processed stainless steel coil by emitting infrared light through the operation panel, and then display the measurement results on a screen for easier observation by the operator, thereby improving the processing efficiency of stainless steel coils. However, this device still has the following problems:

[0004] 1. When the processed stainless steel sheets are cut and output, inaccurate alignment may occur, resulting in a messy stacking.

[0005] 2. Rollers are consumable parts, and each replacement is time-consuming, reducing processing efficiency.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A self-positioning quick-assembly steel plate flatbed machine includes a straightening and cutting machine 1 and a belt conveyor 2;

[0033] The straightening and cutting machine 1 is equipped with a quick-change straightening mechanism 4 for straightening steel plates and cutting them to a specified length;

[0034] The belt conveyor 2 is connected to an automatic alignment mechanism 5 for centering and aligning the steel plates after straightening and cutting.

[0035] The automatic alignment mechanism 5 includes a drive assembly 51, a transmission assembly 52, an alignment assembly 53, and a roller 54; both the drive assembly 51 and the transmission assembly 52 are connected to the belt conveyor 2, and both the drive assembly 51 and the alignment assembly 53 are connected to the transmission assembly 52; the roller 54 is connected to the alignment assembly 53; the drive assembly 51 is used to provide driving force; the transmission assembly 52 is used for transmission; the alignment assembly 53 is used to center and align the steel plate; and the roller 54 is used to reduce friction.

[0036] In this invention, one end of the unfolded steel coil enters the interior of the straightening and cutting machine 1. The quick-change straightening mechanism 4 straightens and cuts the steel coil. The cut steel plate is conveyed to the left by the belt conveyor 2. At the left end of the belt conveyor 2, the drive assembly 51 drives the alignment assembly 53 through the transmission assembly 52 to center the steel plate. At the same time, the roller 54 rolls with the steel plate to reduce friction and achieve centering of the steel plate. When the rollers of the quick-change straightening mechanism 4 need to be replaced, the structure of the quick-change straightening mechanism 4 allows for convenient replacement of the rollers.

[0037] The drive assembly 51 includes a cylinder 511 and a drive block 512; the cylinder 511 is fixedly connected to the base of the belt conveyor 2, and the drive end of the cylinder 511 is fixedly connected to the lower end of the drive block 512; both the left and right ends of the drive block 512 are connected to the transmission assembly 52.

[0041] In this utility model, when the cut steel plate is conveyed on the belt conveyor 2, the cylinder 511 drives the drive block 512 to move down, and the drive block 512 drives the two transverse plates 523 to move closer to each other through the first connecting rod 521. At this time, the transverse plates 523 drive the slider 525 to slide at the upper limit of the slide rail 524. The transverse plates 523 push the two transverse push plates 531 to move closer to the middle. At the same time, the transverse plates 523 drive the lower pressing block 532 to press down through the second connecting rod 522, so as to realize the centering and positioning of the steel plate, and at the same time prevent the two sides from being squeezed during the centering and positioning, causing the middle of the steel plate to bulge.

[0042] The quick-change straightening mechanism 4 includes a straightening assembly 41, a quick-change straightening roller assembly 42, and a cutting machine 43; multiple sets of quick-change straightening roller assemblies 42 are connected to the straightening and cutting machine 1; the quick-change straightening roller assembly 42 is connected to the straightening assembly 41, and the cutting machine 43 is fixedly installed at the left end of the straightening and cutting machine 1; the straightening assembly 41 is used to rotate and straighten the steel plate; the quick-change straightening roller assembly 42 is used to quickly replace the straightening assembly 41; the quick-change straightening roller assembly 42 is symmetrically installed at the left and right ends of the straightening assembly 41; the cutting machine 43 is used to cut the steel plate into corresponding lengths.

[0043] The cutting machine 43 uses existing mature technology, such as a steel plate cutting machine disclosed in Chinese patent CN108296541A.

[0044] The straightening assembly 41 includes a lower straightening roller 411 and an upper straightening roller 412. Multiple lower straightening rollers 411 and upper straightening rollers 412 are arranged at equal intervals on the straightening and cutting machine 1. The left and right ends of the lower straightening rollers 411 and upper straightening rollers 412 are connected to the straightening roller quick-change assembly 42. The multiple lower straightening rollers 411 and upper straightening rollers 412 correspond one-to-one.

[0045] The quick-change straightening roller assembly 42 includes an upper fixed shell 421, a lower fixed shell 422, a rotating shaft 423, a protrusion 424, a groove 425, and a locking block 426. The lower fixed shell 422 is fixedly connected to the straightening and cutting machine 1, and the rear ends of the upper fixed shell 421 and the lower fixed shell 422 are hinged through the rotating shaft 423. The front end of the upper fixed shell 421 is fixedly installed with a protrusion 424, and the front end of the lower fixed shell 422 is provided with a groove 425. The groove 425 is engaged with the protrusion 424. The front ends of both the protrusion 424 and the lower fixed shell 422 are provided with locking slots 427. The locking slots 427 are slidably connected to the locking block 426.

[0046] In this invention, when changing the roll, the operator only needs to pull out the locking block 426; then rotate the upper fixing shell 421 around the rotating shaft 423 to remove and replace the roll. Then, the upper fixing shell 421 is reset around the rotating shaft 423. At this time, the contour grooves opened inside the upper fixing shell 421 and the lower fixing shell 422 cooperate to hold the bearings at both ends of the roll tightly; at the same time, the protrusion 424 and the groove 425 engage. Then, the locking block 426 is inserted into the locking position along the locking groove 427 to complete the roll replacement. This saves more time than the existing method that requires tightening multiple screws and then completely removing the upper fixing shell 421 before replacement.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
