Description

Technical Field

[0001] The present application relates to the technical field of plate processing, and in particular to a steel coil flattening and feeding device. Background Art

[0002] V-shaped plate is a kind of machined part, which is generally produced by stamping and forming with a stamping die. During processing, the plate needs to be placed on the lower die of the stamping equipment. After the upper die moves down, it cooperates with the lower die to extrude and cut the plate first, and then extrude the cut plate.

[0003] In the related art, V-shaped plates are generally fed with steel coils during processing. In order to ensure that the plates can be automatically fed during stamping, a steel coil leveling machine is usually installed between the stamping equipment and the steel coil unwinding rack. The steel coil is flattened and fed through multiple pressure rollers on the steel coil leveling machine, so that the stamping equipment can perform continuous stamping processing on the plates.

[0004] However, in the actual production process, when the steel coil is initially introduced into the steel coil leveling machine, in order to adjust the posture and position of the steel plate so that the plate can better adapt to the stamping equipment, the staff is required to manually insert the end of the steel coil into the gap between the upper and lower pressure rollers in the steel coil leveling machine and adjust the posture of the plate. However, in order to better flatten the plate, the gap between the upper and lower pressure rollers of the steel coil leveling machine is relatively small. Therefore, it is very difficult for the staff to operate when inserting the steel coil into the gap between the pressure rollers, which is very inconvenient.

[0005] In view of the above problems, a steel coil flattening and feeding device is now designed. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] An embodiment of the present application provides a steel coil flattening and feeding device, which can solve the problem in the related art that it is inconvenient to operate when the staff needs to manually insert the steel coil into the gap between the upper and lower pressure rollers in the steel coil leveling machine.

[0030] See also Figure 1-Figure 4 , a steel coil flattening and feeding device, comprising: a base 1, a first pressing roller assembly 2, a second pressing roller assembly 3, an adjusting assembly 4 and a driving assembly 5, the first pressing roller assembly 2 comprises two groups of first guide rollers 21 and a plurality of lower pressing rollers 22, the first guide rollers 21 and the lower pressing rollers 22 are both rotatably arranged on the base 1, and the plurality of lower pressing rollers 22 are arranged between the two groups of first guide rollers 21, the second pressing roller assembly 3 comprises two groups of second guide rollers 31 and a plurality of upper pressing rollers 32, and the plurality of upper pressing rollers 32 are arranged between the two groups of second guide rollers 31, the two groups of the second guide rollers 31 are respectively arranged above the two groups of first guide rollers 21, the upper pressing rollers 32 are located above the lower pressing rollers 22, and the plurality of upper pressing rollers 32 and the plurality of lower pressing rollers 22 are staggered;

[0031] The adjusting assembly 4 includes a transmission assembly 41 and two groups of lifting assemblies 42. The two groups of lifting assemblies 42 are respectively arranged on both sides of the upper pressing roller 32. The lifting assembly 42 includes a fixed plate 421 and a threaded rod 422. The fixed plate 421 is slidably arranged on the base 1. The threaded rod 422 is rotatably arranged on the base 1. The threaded rod 422 penetrates the fixed plate 421 and is threadedly connected thereto. The two groups of fixed plates 421 are rotatably connected to the second guide roller 31 and the two ends of the upper pressing roller 32 respectively. The transmission assembly 41 is arranged on the base 1 and connected to the two groups of threaded rods 422 to drive the threaded rods 422 to rotate.

[0032] The driving assembly 5 is disposed on the base 1 and connected to the two sets of first material guide rollers 21 and the two sets of second material guide rollers 31 to drive the first material guide rollers 21 and the second material guide rollers 31 to rotate;

[0033] In this way, when the V-shaped plate is processed by the stamping equipment and the steel coil needs to be flattened and fed, the two sets of threaded rods 422 can be driven to rotate by the transmission assembly 41. In this way, the threaded rods 422 can drive the two sets of fixed plates 421 to move upward through the threaded connection with the fixed plate 421 during the rotation process, thereby driving the second guide roller 31 and the upper pressure roller 32 to move upward through the fixed plate 421, thereby increasing the distance between the first pressure roller assembly 2 and the second pressure roller assembly 3.

[0034] Then the staff can pass the steel plate through the gap between the first pressing roller assembly 2 and the second pressing roller assembly 3, and adjust the posture and position of the steel plate so that the steel plate can better cooperate with the stamping equipment;

[0035] After the state of the steel plate is adjusted, the transmission assembly 41 can be used to drive the two sets of threaded rods 422 to reverse, and the threaded rods 422 and the fixed plate 421 can be used to drive the fixed plate 421 to move downward, so that the second guide roller 31 and the upper pressing roller 32 can be driven to move downward through the fixed plate 421, thereby reducing the gap between the first pressing roller assembly 2 and the second pressing roller assembly 3, so that the second guide roller 31 and the upper pressing roller 32 are closely attached to the upper end surface of the steel plate, and the first guide roller 21 and the lower pressing roller 22 are closely attached to the lower end surface of the steel plate, so as to limit and fix the steel plate;

[0036] Then, the first guide roller 21 and the second guide roller 31 can be driven to rotate by the driving assembly 5, so that the steel plate can be extruded and fed by the cooperation of the first guide roller 21 and the second guide roller 31, and the steel plate can be extruded and flattened by the staggered upper pressure rollers 32 and the lower pressure rollers 22, so as to facilitate the flattening and feeding of the steel plate;

[0037] In this way, when in use, the distance between the first pressing roller assembly 2 and the second pressing roller assembly 3 can be adjusted as needed to facilitate the staff to place the steel plate, and when the steel plate needs to be fed, the first pressing roller assembly 2 and the second pressing roller assembly 3 are moved down and reset to squeeze the steel plate. This facilitates the operation of the staff and is highly practical.

[0038] See also Figure 5 In this embodiment, the transmission assembly 41 includes a first hand wheel 411, a connecting plate 412, two groups of first gears 413 and two groups of racks 414. The two groups of the first gears 413 are respectively sleeved on the two groups of threaded rods 422. The connecting plate 412 is slidably arranged on the base 1. The two groups of racks 414 are both arranged on the connecting plate 412. The two groups of racks 414 are respectively meshed with the two groups of first gears 413. The first hand wheel 411 is arranged on one of the threaded rods 422.

[0039] In this way, when it is necessary to adjust the height of the first pressure roller assembly 2, the staff can rotate the first hand wheel 411, and drive one of the threaded rods 422 to rotate through the first hand wheel 411, so that when the threaded rod 422 rotates, it will drive the first gear 413 to rotate, and at the same time, the first gear 413 will push the connecting plate 412 to move through the meshing transmission with the rack 414 during the rotation process, so that the connecting plate 412 will drive the two sets of racks 414 to move, and then the rack 414 will drive the other threaded rod 422 to rotate through the meshing transmission with the other set of first gears 413, so that the two sets of threaded rods 422 can rotate at the same time, so as to drive the fixing plate 421 to rise and fall;

[0040] In this way, the staff only needs to turn the first hand wheel 411 to adjust the distance between the first pressing roller assembly 2 and the second pressing roller assembly 3, which is convenient for the staff to operate and has strong practicality.

[0041] Preferably, the base 1 is provided with a plurality of guide rods 11, and the guide rods 11 penetrate the fixing plate 421 and are slidably connected thereto;

[0042] In this way, through the limiting effect of the sliding connection between multiple guide rods 11 and the fixed plate 421, the fixed plate 421 can only move in a straight line along the guide rods 11, thereby preventing the fixed plate 421 from offsetting during the movement and affecting the coordination between the first pressure roller assembly 2 and the second pressure roller assembly 3. The stability of the device during use can be ensured, which facilitates use.

[0043] Specifically, in the present embodiment, the driving assembly 5 comprises a motor, a linkage assembly, a chain 51, two groups of sprocket wheels 52, two groups of second gear wheels 53 and two groups of third gear wheels 54. The two groups of sprocket wheels 52 are respectively arranged on the two groups of first guide rollers 21. The chain 51 is sleeved on the two groups of sprocket wheels 52 and matched therewith. The two groups of the second gear wheels 53 are respectively arranged on the two groups of first guide rollers 21. The two groups of the third gear wheels 54 are respectively arranged on the two groups of second guide rollers 31. The two groups of the third gear wheels 54 are respectively meshed with the two groups of the second gear wheels 53. The motor is arranged on the base 1, and the motor is connected to one of the first guide rollers 21 through the linkage assembly.

[0044] In this way, when the steel plate needs to be fed, the motor can drive one of the first guide rollers 21 to rotate through the linkage assembly, so that when the first guide roller 21 rotates, the sprocket 52 will be driven to rotate, and then the sprocket 52 will drive the other sprocket 52 to rotate through the chain 51, so that the two sets of first guide rollers 21 rotate at the same time;

[0045] In this way, the first guide roller 21 will drive the two sets of second gears 53 to rotate when rotating, and then the second gear 53 will drive the two sets of third gears 54 to reverse through the meshing transmission with the third gear 54 during the rotation process, thereby driving the two sets of second guide rollers 31 to reverse through the third gear 54, so that the steel plate can be extruded and fed through the two sets of rotating first guide rollers 21 and the two sets of second guide rollers 31;

[0046] At the same time, the second gear 53 and the third gear 54 in the present application are gears of uniform specifications, so that the first guide roller 21 and the second guide roller 31 are driven to rotate through the meshing transmission of the second gear 53 and the third gear 54, so that the first guide roller 21 and the second guide roller 31 can be rotated synchronously, thereby preventing the steel plate from slipping during the feeding process and affecting the accuracy of the steel plate feeding. In this way, the accuracy of the steel plate feeding can be guaranteed, and the practicability is strong.

[0047] It should be noted that the linkage component in the present application can be a belt drive or a chain drive. In the present application, driving the motor through the linkage component is an existing conventional technology and is a device that can be purchased on the market. It is not an improvement point of the present application, so no further description will be given.

[0048] More specifically, the driving assembly 5 further includes a second hand wheel 55, and the second hand wheel 55 is disposed on one of the first guide rollers 21;

[0049] When the staff puts the steel plate between the upper pressing roller 32 and the lower pressing roller 22, and needs to feed the steel plate, the staff can manually turn the second hand wheel 55 to drive one of the first guide rollers 21 to rotate, and then the two sets of first guide rollers 21 and the two sets of second guide rollers 31 can be driven to rotate through the coordinated transmission of the chain 51, the sprocket 52, the second gear 53 and the third gear 54, so as to manually feed the steel plate;

[0050] In this way, the staff can manually adjust the length of the steel plate extending outward by turning the second hand wheel 55, so that the steel plate can better adapt to the stamping equipment for subsequent stamping and forming. After manual adjustment, the device can be started to automatically feed the steel plate, which is very practical.

[0051] Furthermore, in this embodiment, a bracket 6 is provided on one side of the base 1, and two sets of rotating shafts 7 are rotatably provided on the bracket 6, and both sets of rotating shafts 7 are parallel to the first guide roller 21;

[0052] In this way, when inserting the steel coil between the first guide roller 21 and the second guide roller 31, the steel coil can be inserted between the two sets of rotating shafts 7 first. In this way, when the steel coil is pulled and fed by the first guide roller 21 and the second guide roller 31, the steel coil can be guided and limited by the two sets of rotating shafts 7 first, so that the steel coil can enter between the first guide roller 21 and the second guide roller 31 horizontally.

[0053] Avoid warping of some edges of the steel coil, which causes the steel coil to get stuck at the edges of the first guide roller 21 and the second guide roller 31, so as to avoid the device from getting stuck during operation, thereby making the steel coil feeding smoother and more convenient to use.

[0054] See also Figure 2 In this embodiment, two sets of limit members 8 are provided on both sides of the base 1, and the limit members 8 include a support member 81 and a guide wheel 82. The support member 81 is provided on the base 1, and the guide wheel 82 is provided on the support member 81 and is rotatably connected thereto;

[0055] In this way, both sides of the steel coil can be closely attached to the guide wheel 82. When the steel coil is being fed, the steel coil will drive the guide wheel 82 to rotate. In this way, the guide and limiting function of the four sets of guide wheels 82 can be used to limit the steel coil, thereby preventing the steel coil from deviating during the feeding process and affecting the stamping quality of the steel plate. The steel coil is highly practical.

[0056] The support member 81 includes a threaded column 811 and two sets of nuts 812. The threaded column 811 is provided on the base 1. The two sets of nuts 812 are sleeved on the threaded column 811 and threadedly connected thereto. The guide wheel 82 is sleeved on the threaded column 811 and rotatably connected thereto. The guide wheel 82 is located between the two sets of nuts 812.

[0057] In this way, when in use, the height of the guide wheel 82 can be adjusted by screwing the two sets of nuts 812. At the same time, the two sets of nuts can be made close to the two sides of the guide wheel 82, thereby clamping and fixing the guide wheel 82. In this way, the height of the guide wheel 82 can be adjusted, so that the guide wheel 82 can be adjusted to a suitable position to better cooperate with the first guide roller 21 and the second guide roller 31 for use, which is highly practical.
