Description

Technical Field

[0001] The invention belongs to the technical field of cold-bent steel production, and in particular relates to a cold-bent steel production and receiving device. Background Art

[0002] Cold-formed steel is made from hot-rolled or cold-rolled strip steel through a cold-bending process. It has a variety of cross-sectional shapes, including common channel steel and angle steel, and can also be customized for special shapes. The cold-bending process increases the strength of the steel, resulting in high dimensional accuracy, excellent surface quality, and good cold working properties. It is easy to cut and weld. It is used in a wide range of applications, including roof trusses and purlins in construction, structural parts in machinery manufacturing, and vehicle frames in the automotive industry. This technical solution is primarily targeted at I-shaped steel. The traditional material receiving device has a relatively simple function. It only has a single material receiving function inside the device. In addition, some small factories still use manual material receiving. When there are too many workpieces that need to be received, it will greatly consume labor costs and have low efficiency. Summary of the Invention

The pushing component is used to push the steel section into the material receiving shell, and the outer surface of the steel section can be cleaned during the pushing process. Because the outer surface of the steel section is in contact with various machines for a long time during the processing, there will be too many impurities on the surface. The lifting component is used to assist the pushing component to stack the steel section regularly.

[0015] With the above technical solution, the rotation of the screw rod drives the vertical plate to slide inside the mounting shell using the slider, and the vertical plate can be retracted using the second spring push rod.

[0016] The present invention is further configured as follows: a cleaning wheel is rotatably connected inside the limit shell, a second bevel gear is fixedly connected to the lower end of the cleaning wheel, and the second bevel gear is meshingly connected to the first bevel gear, one end of a group of the second rotating rods is bolted to an electric push rod, the piston end of the electric push rod is bolted to a third bevel gear, and a push plate is welded to one side of the vertical plate.

[0017] By adopting the above technical solution, the second rotating rod will use the first bevel gear and the second bevel gear to drive the cleaning wheel to rotate, and the cleaning wheel can clean the outer surface of the steel section.

[0024] In summary, the present invention has the following beneficial effects: During use, the staff places the I-shaped steel on the upper end of the connecting plate inside the two sets of partitions, and then uses the pushing component to push the I-shaped steel into the inside of the material receiving shell. While pushing the I-shaped steel, the pushing component will synchronously clean the impurities on both sides of the outer surface of the I-shaped steel. Because the outer surface of the I-shaped steel will often come into contact with multiple machines during the production process, there will be more impurities on the outer surface that need to be removed, and a total of three groups of I-shaped steel can be placed at the same time. When pushing to the third group of I-shaped steel, the pushing component will drive the lifting component to operate. When the third group of I-shaped steel is pushed into the inside of the material receiving shell, the lifting component will synchronously drive the placement plate to move down on the slide rod surface, and then drive the material receiving shell to move down, which can facilitate the regular stacking of multiple groups of I-shaped steel. Together, it reduces the space occupied by the I-shaped steel for collecting materials, and then starts pushing from the first group of I-shaped steel again, and circulates in sequence. When the first group of I-shaped steel is placed inside the two groups of partitions for pushing, the second group of I-shaped steel can be placed inside the other two groups of partitions. When pushing the second group of I-shaped steel, the third group of I-shaped steel is placed inside the last two groups of partitions, and circulates in sequence. In this way, compared with placing three groups at the same time inside the partition and pushing them at the same time, only one group of I-shaped steel is pushed each time, and the required thrust is relatively small. Compared with pushing three groups of I-shaped steel at the same time, the power requirements for the pushing equipment are lower, the equipment is more likely to meet the pushing requirements, and it can also reduce the wear and failure probability of the equipment, thereby achieving the effect of facilitating the pushing, cleaning and regular collection of I-shaped steel.

A lifting component 7 is provided at the upper end of the base plate 2. Six groups of partitions 8 are welded to the upper end of the base frame 1. A connecting plate 9 is welded to one side of the partition 8. A pushing component 6 is provided at the upper end of the base frame 1.

[0029] Brief description of the usage process: When in use, the staff places the I-shaped steel on the upper end of the connecting plate 9 inside the two groups of partitions 8, and then uses the pushing component 6 to push the I-shaped steel into the inside of the material receiving shell 5. While pushing the I-shaped steel, the pushing component 6 will synchronously clean the impurities on both sides of the outer surface of the I-shaped steel. Because the outer surface of the I-shaped steel will often come into contact with multiple machines during the production process, there will be more impurities on the outer surface that need to be removed, and a total of three groups of I-shaped steel can be placed at the same time. When pushing to the third group of I-shaped steel, the pushing component 6 will drive the lifting component 7 to operate. When the third group of I-shaped steel is pushed into the inside of the material receiving shell 5, the lifting component 7 will synchronously drive the placing plate 4 to move down on the surface of the slide rod 3, thereby driving the material receiving shell 5 to move down, which can facilitate more The groups of I-shaped steel are stacked together regularly to reduce the space occupied by the I-shaped steel collection, and then the pushing starts again from the first group of I-shaped steel, and the cycle is continued. When the first group of I-shaped steel is placed inside the two groups of partitions for pushing, the second group of I-shaped steel can be placed inside the other two groups of partitions. When the second group of I-shaped steel is pushed, the third group of I-shaped steel is placed inside the last two groups of partitions, and the cycle is continued. Compared with placing three groups of I-shaped steel inside the partitions at the same time and pushing them at the same time, only one group of I-shaped steel is pushed each time, and the required thrust is relatively small. Compared with pushing three groups of I-shaped steel at the same time, the power requirements for the pushing equipment are lower, the equipment is more likely to meet the pushing requirements, and the wear and failure probability of the equipment can be reduced, thereby achieving the effect of facilitating the pushing, cleaning and regular collection of I-shaped steel.

The surface of the slide 601 is slidably connected to a sliding shell 606, and the internal bolts of the sliding shell 606 are connected to a dual-axis motor 603; one of the output ends of the dual-axis motor 603 is bolted to a first circular gear 604, and the first circular gear 604 is meshed with the first tooth plate 602, and the other set of output ends of the dual-axis motor 603 is bolted to a second circular gear 605. The upper end of the chassis 1 is close to the partition 8. The ends of the two sets of fixed plates 608 are bolted together with two groups of first spring push rods 607, and the piston ends of the corresponding two groups of first spring push rods 607 are commonly bolted together with a fixed plate 608; the middle part of the fixed plate 608 is rotatably connected to a first rotating rod 609, one end of the first rotating rod 609 is fixedly connected to a third circular gear 610, and one end of the third circular gear 610 is fixedly connected to a screw rod 614, and the screw rod 614 is rotatably connected to the inside of another set of fixed plates 608, and the two ends of the two sets of fixed plates 608 are commonly rotatably connected with a second rotating rod 611; the two groups of second rotating rods 611 and the surface of the screw rod 614 are commonly connected. Four sets of transmission wheels 612 are welded, and a belt 613 is commonly connected between two corresponding sets of transmission wheels 612. Three sets of mounting shells 625 are welded on the upper end of the chassis 1, and the mounting shells 625 are arranged between two adjacent sets of partitions 8. A slider 616 is slidably connected inside the mounting shell 625; the upper end of the slider 616 is bolted to two sets of second spring push rods 615, and the piston ends of the two sets of second spring push rods 615 are commonly bolted to a vertical plate 617, and the vertical plate 617 and the slider 616 are slidably connected, and the vertical plate 617 and the screw rod 614 are threadedly connected. The surface of the second rotating rod 611 is fixedly connected to the first bevel gear 618, and a limiting shell 620 is welded to the side of the partition 8 close to the first bevel gear 618; the interior of the limiting shell 620 is rotatably connected to a cleaning wheel 621, and the lower end of the cleaning wheel 621 is fixedly connected to the second bevel gear 619, and the second bevel gear 619 and the first bevel gear 618 are meshedly connected, one end of a group of second rotating rods 611 is bolted to an electric push rod 624, the piston end of the electric push rod 624 is bolted to the third bevel gear 622, and a push plate 623 is welded to one side of the vertical plate 617.

[0031] Brief description of the use process: When one of the conveying ends of the dual-axis motor 603 is running, it will drive the first circular gear 604 to rotate. Since the first tooth plate 602 is fixed and the first circular gear 604 is meshed with the first tooth plate 602, the first circular gear 604 will drive the dual-axis motor 603 to slide on the surface of the slide plate 601 using the sliding shell 606. When sliding to a certain position, the second circular gear 605 will contact the third circular gear 610, thereby causing the third circular gear 610 to move downward, thereby causing the first rotating rod 609, the fixed plate 608, the screw rod 614, and the vertical plate 617 (on the sliding plate) to rotate. The second rotating rod 611 is synchronously moved downward by the first spring push rod 607 and the second spring push rod 615, and then the second circular gear 605 is meshed with the third circular gear 610. When the dual-axis motor 603 drives the third circular gear 610 to rotate by the second circular gear 605, the third circular gear 610 drives the screw rod 614 to rotate, and then the vertical plate 617 is driven by the screw rod 614 to move inside the mounting shell 625 by the slider 616, so that the push plate 623 moves with the vertical plate 617 and pushes the I-shaped steel, so that the I-shaped steel moves to the receiving shell 5 Internally, due to the use of the transmission wheel 612 and the belt 613, the screw rod 614 will drive the two sets of second rotating rods 611 to rotate, and then the second rotating rod 611 will use the first bevel gear 618 and the second bevel gear 619 to drive the cleaning wheel 621 to rotate. The cleaning wheel 621 can clean the impurities on both sides of the outer surface of the I-shaped steel, and when the second rotating rod 611 moves down, the cleaning wheel 621 will move down synchronously inside the limit shell 620. When the third set of I-shaped steel is pushed, the electric push rod 624 (using a rechargeable or battery-powered type) will push the third bevel gear 622 forward and align with the fourth bevel gear When the wheel 703 is engaged, the pushing assembly 6 will drive the lifting assembly 7 to operate. Due to the transmission ratio setting of the third bevel gear 622 and the fourth bevel gear 703, when the third bevel gear 622 rotates one circle, the fourth bevel gear 703 rotates less than one circle, and when the inclined shell 701 moves to both sides, it also needs to move a certain distance before the placement plate 4 can be separated from the uppermost end of the inclined shell 701. Therefore, after the I-shaped steel is pushed into the inside of the receiving shell 5, the placement plate 4 will move down, which makes it easy to push the I-shaped steel into the inside of the receiving shell 5 and to clean both sides of the outer surface of the I-shaped steel.

[0032] Example 3: Based on Example 2, Figure 2 、 Figure 5 、 Figure 7, the lifting assembly 7 includes a sloped shell 701, two groups of sloped shells 701 are respectively slidably connected to both sides between the placement plate 4 and the bottom plate 2, and the upper and lower ends of the two groups of sloped shells 701 are rotatably connected to a number of groups of rollers 702, and one side of the two groups of sloped shells 701 is welded with a second tooth plate 707, and the two groups of second tooth plates 707 are meshed and connected to set a fifth circular gear 710, one of which is a group of second tooth plates 707 internally slidably connected to a limit plate 708, and the limit plate 708 is welded to the upper end of the bottom plate 2; the lower end of the fifth circular gear 710 is fixedly connected to a first rotating shaft 709, and the first rotating shaft 709 is rotatably connected to the upper end of the bottom plate 2, and the bottom plate 2 is close to the second One side of the tooth plate 707 is rotatably connected to the second rotating shaft 713, and the upper end of the second rotating shaft 713 is fixedly connected to the fourth circular gear 706, and the fourth circular gear 706 is meshingly connected to one group of second tooth plates 707, and the upper end of the fourth circular gear 706 is fixedly connected to the hollow shell 705; the bottom bottom of the hollow shell 705 is bolted with a third spring push rod 711, the piston end of the third spring push rod 711 is fixedly connected to the sliding column 704, and the sliding column 704 and the hollow shell 705 are slidingly connected, the upper end of the sliding column 704 is fixedly connected to the fourth bevel gear 703, and the fourth bevel gear 703 is meshingly connected to the third bevel gear 622.

[0033] The operation process is briefly described as follows: when the third group of second rotating rods 611 moves downward, it will drive the third bevel gear 622 to press the fourth bevel gear 703 downward, so that the sliding column 704 slides inside the hollow shell 705, and the third spring push rod 711 is pressed down and retracted. As the fourth bevel gear 703 is driven to rotate, the sliding column 704 drives the hollow shell 705 to rotate using the second rotating shaft 713, and then drives the fourth circular gear 706 to rotate. The fourth circular gear 706 will drive one group of second tooth plates 707 to move. Since the fifth circular gear 710 can be used The first rotating shaft 709 is rotated, and the fifth circular gear 710 is engaged between the two groups of second tooth plates 707, so the two groups of second tooth plates 707 will move in opposite directions. Because the two groups of second tooth plates 707 are fixedly connected to the two groups of inclined shells 701 respectively, the two groups of inclined shells 701 will drive the rollers 702 to move to both sides. The rollers 702 facilitate the inclined shells 701 to move more smoothly on the surfaces of the placement plate 4 and the bottom plate 2. The placement plate 4 will move downward according to the height change of the inclined shell 701, thereby achieving the effect of facilitating the regular arrangement and placement of the I-shaped steel.

After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
