Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy annealing technology, specifically relating to an aluminum coil support rack for a box-type annealing furnace. Background Technology

[0002] In the production process of cast and rolled aluminum, aluminum annealing mainly relies on box-type annealing furnaces. For box-type annealing furnaces, the amount of coils loaded into the furnace is a necessary means to improve production efficiency. Therefore, the requirement for full-load loading of the annealing furnace will be a huge challenge. Taking the 65-ton annealing furnace currently in use as an example, the furnace door height is 3700mm and the depth is 8150mm. However, the space utilization rate of a single-layer rack is low, and the overall height does not exceed 2020mm, which makes it impossible to meet the development requirements of full-load annealing.

[0003] The purpose of this invention is to provide an aluminum coil support rack for a box-type annealing furnace to solve the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A support rack for aluminum coils in a box-type annealing furnace includes a driven support frame, an active support frame, and a base plate. The driven support frame and the active support frame are arranged in parallel. Several material feeding trays are provided on the top of the driven support frame and the active support frame. Several cooperating connecting rods I and II are respectively provided on the bottom of the driven support frame and the active support frame. The free end of the connecting rod I is provided with a hole, and the free end of the connecting rod II is provided with a rod. The rod passes through the hole. The bottom surface of the connecting rods I and II is provided with a slide rail. Several sliding grooves that cooperate with the slide rails are provided on the base plate. Support rods are provided at the bottom of the base plate.

[0006] To further realize this utility model, the arc of the feeding tray is φ410mm, and the feeding tray includes a high feeding tray and a low feeding tray arranged at intervals, with the high feeding tray and the low feeding tray located on the same plane.

[0007] To further realize this utility model, the length of the slide groove is greater than the sum of the lengths of connecting rod I and connecting rod II.

[0008] To further realize this utility model, both the driven support frame and the active support frame include a lower frame and an upper frame. The lower frame includes an upper crossbar and a lower crossbar, with several uprights arranged between the upper and lower crossbars. The upper frame includes several isosceles triangular supports and right-angled triangular supports. The isosceles triangular supports are continuously arranged on the top surface of the upper crossbar. A high-position material feeding support is provided at the top of the isosceles triangular supports, and a low-position material feeding support is provided between two adjacent isosceles triangular supports. Right-angled triangular supports are provided on the outer sides of the two outermost isosceles triangular supports. The longitudinal bars of the right-angled triangular supports are on the same straight line as the uprights at both ends of the lower frame.

[0009] To further realize this utility model, a reinforcing rod is provided at the axial position of the isosceles triangular support, and the reinforcing rod and the upright are on the same straight line.

[0010] To further realize this utility model, the slide rail includes two parallel rails, and the number of slide grooves matches the slide rail.

[0011] To further realize this utility model, the length of the insertion rod and the depth of the insertion hole are both 400mm, the cross-section of the insertion rod is 100×100mm, and the insertion rod is embedded in the insertion hole. This ensures that the rod does not tip over after the spacing is changed.

[0012] To further realize this utility model, the distance between the top surface of the lower shelf and the ground is 1010mm, and the distance between the highest point of the high-position material tray and the ground is 2020mm.

[0013] The advantages of this utility model compared to the prior art are as follows:

[0014] This invention addresses the requirement of full furnace loading under varying widths and coil diameters in aluminum alloy annealing processes. By increasing the loading depth from a single layer to a double layer, the furnace space of the box-type annealing furnace is fully utilized, effectively increasing the loading capacity and the performance precision of the annealed aluminum coils, thereby further improving production efficiency and product quality.

[0015] This utility model allows the slide rails on the bottom surface of the driven support frame and the active support frame to coincide with the corresponding slide rails on the base plate, enabling the 1650mm and 2350mm specification changes to meet the needs of steel sleeve erection for different cold rolling mills.

[0016] The materials required for this utility model are simple, readily available, and inexpensive. Installation, replacement, and disassembly are simple and easy to implement. Different specifications can be changed through a simple mechanical structure, which requires less professional skills from personnel and is widely used on site. Attached Figure Description
