Description

Technical Field

[0001] The utility model relates to the technical field of hoists, and particularly relates to a rib pressing equipment for an intermediate section housing. Background Art

[0002] The intermediate section is a main component of a bucket elevator. Each section is 2.0 - 2.5 meters high, and the sections are connected by bolts to form the elevator housing. The number of intermediate sections can be increased or decreased according to the height of the elevator, and it is the component with the largest demand in the elevator housing. At present, the forms of intermediate sections of bucket elevators at home and abroad are relatively unified, mainly composed of four-sided housing plates, upper and lower mounting flanges on both sides, and vertical reinforcing ribs evenly distributed on the sides. The four-sided housing plates are mainly made of steel plates with a thickness of 4 - 5 mm. The upper and lower mounting flanges on both sides have two forms of angle steel and flat steel, and there are various forms of vertical reinforcing ribs. Some use flat steel or angle steel for welding reinforcement, and some use triangular or trapezoidal ribs directly pressed on the four-sided housing plates for reinforcement.

[0003] Using different forms of reinforcing ribs has different advantages and disadvantages:

[0004] First, using flat steel or angle steel for welding as the reinforcing rib is relatively flexible, without the need for profiling equipment and molds. However, since it is necessary to weld and reinforce the four-sided housing plates, and the thickness of the four-sided housing plates is 4 - 5 mm, the welding deformation of the four-sided housing plates is relatively obvious, which has a more prominent impact on the product appearance.

[0005] Second, using directly pressing reinforcing ribs on the four-sided housing plates, the forming of the four-sided housing plates is better, and the overall steel consumption is lower than that using flat steel or angle steel as the reinforcing rib. However, it requires profiling equipment and molds. At the same time, due to the different structures and sizes of each type of intermediate section, there are differences such as single-sided pressing of single ribs, single-sided pressing of double ribs, and different distances between single-sided double ribs.

[0006] In the prior art, generally, the method of using flat steel or angle steel for welding reinforcement is adopted. There is welding deformation in the four-sided housing plates, which seriously affects the product appearance. At the same time, the steel consumption is larger compared with the rib pressing form. Considering from the aspects of product appearance quality and long-term cost, rib pressing for the intermediate section is a better choice. The existing profiling equipment in the market has defects such as high cost, large floor area of the equipment, and long finished product cycle of the equipment. In addition, for the general profiling equipment in the market, for situations such as single-sided pressing of double ribs and different distances between single-sided double ribs, multiple forming is required and it cannot be formed at one time. Content of the Utility Model

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art, and provides a rib pressing equipment for an intermediate section housing to meet the different rib pressing requirements of the four-sided housing plates of intermediate sections with different structures and sizes, improve the product quality, and save the manufacturing cost.

The fixed machine seat is fixed on the two guide rails, and the movable machine seats are slidably arranged on the two guide rails and can slide back and forth along the two guide rails; each machine seat is provided with an independent ribbing device.

[0022] The embodiments of the present utility model will be described in detail below. These embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0023] Refer to Figures 1 to 4 , this embodiment discloses an intermediate section housing bead pressing equipment, which includes a frame. There are two left and right guide rails 1 on the frame. A plurality of machine bases arranged in the front-rear direction are provided on the two left and right guide rails 1. The left and right ends of each machine base straddle the two left and right guide rails 1. One of the machine bases at the end is a fixed machine base 2, and the rest of the machine bases are movable machine bases 3. The fixed machine base 2 is fixed on the two guide rails 1, and the movable machine base 3 is slidably arranged on the two guide rails 1 and can slide back and forth along the two guide rails 1; independent bead pressing devices are provided on each machine base.

[0024] The bead pressing device includes an upper pressing seat 4 and a workbench 5 which are arranged oppositely up and down. The workbench 5 is fixed on the machine base. A lower die 7 is detachably installed on the top of the workbench 5. The upper pressing seat 4 is slidably installed on the machine base and can move vertically along the machine base. The left and right sides of the upper pressing seat 4 are respectively slidably matched with the left and right sides of the frame through a slide rail and slider assembly 8. An upper die 6 is detachably installed at the bottom of the upper pressing seat 4. Among them, the lower die 7 and the workbench 5, and the upper die 6 and the upper pressing seat can be detachably connected by bolt connection respectively. In this embodiment, the upper die 6 and the lower die 7 are designed to be detachably connected, which is convenient for disassembly and assembly operations when the upper die 6 and the lower die 7 need to be repaired or replaced after wear; and for different structural forms of reinforcing ribs, it is also convenient to replace the upper and lower dies 7 of different specifications, improving the versatility of the bead pressing equipment and saving costs.

[0025] Above the upper pressing seat 4, there are three oil cylinders 9 arranged in the left-right direction. The oil cylinders 9 are installed on the frame. The movable ends of the oil cylinders 9 extend downward and are fixedly connected to the upper pressing seat 4. By simultaneously expanding and contracting the movable ends of the three oil cylinders 9, the upper pressing seat 4 is driven to move vertically. Each base is provided with its own hydraulic system, and the three oil cylinders 9 on the corresponding base are driven to expand and contract synchronously through the hydraulic system. In this embodiment, three oil cylinders 9 are provided to drive the vertical movement of the upper pressing seat 4, which can effectively avoid the flexural deformation of the middle position of the upper pressing seat 4 during the downward pressing process, thus ensuring the consistency of the shapes of all parts of the pressed reinforcing ribs and improving the quality of rib pressing. Moreover, for the rib pressing of the middle-section shell plate with a larger size, this rib pressing equipment can also be applicable and ensure the rib pressing quality.

[0026] The matching form between the bottom of the movable base 3 and the two guide rails 1 is a rolling friction match. On the single side of the bottom of the movable base 3, two roller shafts 12 are rotatably installed. The two ends of each roller shaft 12 are respectively rotatably supported on two bearing seats, and the bearing seats are fixed to the bottom of the movable base 3. The single side of the bottom of the movable base 3 rolls on the top surface of the corresponding guide rail 1 through the two roller shafts 12 to reduce the resistance of the movement of the movable base 3 in the form of rolling friction match. Gears 10 are respectively rotatably arranged at the left and right ends of the base. Rack bars 11 are respectively arranged outside the two guide rails 1. The rack bars 11 extend in the front-rear direction and are fixed on the frame. The gears 10 at the left and right ends of the base are respectively meshed with the left and right rack bars 11. Each movable base 3 is provided with a drive motor for independently driving the corresponding gear 10 to rotate. By driving the gear 10 to rotate through the drive motor, under the cooperation of the gear 10 and the rack bar 11, and under the guiding action of the two guide rails 1, the corresponding movable base 3 is driven to move back and forth, so as to adjust the distance between two adjacent bases to meet the rib pressing requirements of the reinforcing ribs with different distances on the four-sided shell plate.

[0027] The rib pressing equipment provided in this embodiment, by arranging two left and right guide rails 1, and providing a fixed base 2 and multiple movable bases 3 on the two guide rails 1, the rib pressing devices on each base are independent of each other, and one, two or more rib pressing devices on the bases can be selected as the working devices according to needs, so that one, two or more reinforcing ribs can be pressed on a shell plate according to needs, meeting the rib pressing requirements of different rib pressing numbers of the shell plates of various models of the middle section. In addition, its movable base 3 can slide back and forth on the guide rail 1, so as to adjust the distance between each base, so that reinforcing ribs with different distances can be pressed on the shell plate according to needs, meeting the rib pressing requirements of the reinforcing ribs with different distances on the shell plates of different models of the middle section. Therefore, the rib pressing equipment provided in this embodiment can meet the rib pressing requirements of different rib pressing numbers and rib pressing distances of various models of the middle-section shell, ensure the rib pressing quality, and save the manufacturing cost.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model.
