Description

Technical Field

[0002] Annealing furnace is a heat treatment method in which steel pipes are heated to a temperature that causes phase transformation or partial phase transformation, held at that temperature, and then slowly cooled. The purpose of annealing is to eliminate structural defects, improve the microstructure to homogenize the composition and refine the grains, improve the mechanical properties of the steel, and reduce residual stress; simultaneously, it can reduce hardness, improve plasticity and toughness, and improve machinability. Therefore, annealing serves both to eliminate and improve structural defects and internal stresses left over from previous processes and to prepare for subsequent processes; thus, annealing is a semi-finished product heat treatment, also known as pre-heat treatment. When annealing workpieces, they are usually manually pushed into the annealing furnace. To address this, a material feeding device for the annealing furnace is proposed to reduce the inconvenience of manual feeding.

[0003] Most existing annealing furnace material handling devices are custom-made according to the height requirements of the annealing furnace, which is quite troublesome. The existing annealing furnace material handling devices cannot achieve automatic height adjustment, and when transporting the workpiece to the side of the annealing furnace, it is necessary to manually use tools to shovel the workpiece into the annealing furnace. The high temperature of the workpiece can easily burn the workers. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an annealing furnace material feeding device. The technical problem to be solved is that the existing annealing furnace material feeding device cannot be automatically adjusted, and it is dangerous to manually put the workpiece into the annealing furnace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material conveying device for an annealing furnace, comprising a holding platform:

[0006] The lower end of the holding platform is movably equipped with a mobile cart, the lower end of the mobile cart is movably equipped with movable wheels, and a push handle is fixedly provided on one side of the mobile cart;

[0007] The lower end of the serving platform is equipped with a height-adjustable lifting device for lifting the serving platform to adjust its height.

[0008] The lifting and raising device includes a first hinge seat and a second hinge seat, which are fixedly mounted on the upper end of the mobile vehicle.

[0009] The upper end of the holding platform is equipped with a pushing and feeding device that can push the workpiece into the annealing furnace, and is used to automatically push the workpiece into the annealing furnace.

[0013] In a preferred embodiment, a cylinder is fixedly mounted on the upper end of the mobile vehicle via a flange, and a load-bearing block is fixedly mounted on the output end of the cylinder. The upper end of the load-bearing block is fixedly connected to the lower end of the serving platform.

[0014] In a preferred embodiment, the pushing and feeding device includes a forward and reverse motor, which is fixedly mounted on one side of the holding platform via a flange.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model, by incorporating a lifting and raising device, facilitates the height adjustment of the holding platform, making it suitable for material handling in various annealing furnaces. A mobile trolley is fixed at the furnace inlet, and the cylinder extends according to the furnace inlet height, thereby lifting the holding platform.

[0026] like Figure 1 and 2 As shown, this utility model provides a material conveying device for an annealing furnace, including a holding platform 1: a mobile cart 5 is movably provided at the lower end of the holding platform 1, a movable wheel 7 is movably provided at the lower end of the mobile cart 5, a push handle 6 is fixedly provided on one side of the mobile cart 5, and a baffle plate 4 is fixedly provided at the upper end of the holding platform 1.

[0027] In order to lift the serving platform 1 for height adjustment, the lower end of the serving platform 1 is equipped with a height-adjustable lifting device 2 for lifting the serving platform 1 for height adjustment.

[0028] like Figure 3 As shown, the lifting device 2 includes a first hinge seat 21 and a second hinge seat 22. The first hinge seat 21 and the second hinge seat 22 are fixedly mounted on the upper end of the moving vehicle 5. Multiple sets of intersecting first connecting rods 23 and 24 are provided between the first connecting rod 21 and the second hinge seat 22. These multiple sets of intersecting first connecting rods 23 and 24 are distributed vertically, and adjacent sets of first connecting rods 23 and 24 are hinged together. The intersection of the first connecting rods 23 and 24 is movably connected by a hinge block 25. The upper ends of the first connecting rods 23 and 24 are fixedly connected to the movable ends of the third hinge seat 26 and the fourth hinge seat 27, respectively. The upper ends of the third hinge seat 26 and the fourth hinge seat 27 are also fixedly connected to the movable ends of the second connecting rods 24. The upper end of the moving vehicle 5 is fixedly connected to the lower end of the holding platform 1, and a cylinder 28 is fixedly mounted on the upper end of the moving vehicle 5 via a flange. A load-bearing block 29 is fixedly mounted on the output end of the cylinder 28. The upper end of the load-bearing block 29 is fixedly connected to the lower end of the holding platform 1. The moving vehicle 5 is fixed at the inlet of the annealing furnace. The cylinder 28 is activated to extend according to the height of the annealing furnace inlet, thereby lifting the holding platform 1. The first hinge seat 21, the second hinge seat 22, the third hinge seat 26 and the fourth hinge seat 27 are movably connected to the first connecting rod 23 and the second connecting rod 24. Therefore, when the holding platform 1 is raised, the multiple first connecting rods 23 and the second connecting rods 24 perform limited movement, thereby improving the stability of the holding platform 1 during the raising process and achieving the effect of automatic height adjustment.

[0029] Furthermore, in order to avoid burns to personnel, the upper end of the holding platform 1 is equipped with a pushing and feeding device 3 that can push the workpiece into the annealing furnace, which is used to automatically push the workpiece into the annealing furnace.

[0030] like Figure 4 As shown, the feeding device 3 includes a forward and reverse motor 31, which is fixedly mounted on one side of the holding platform 1 via a flange. A slide groove 32 is provided on the inner side of the holding platform 1. The output end of the forward and reverse motor 31 passes through one side of the holding platform 1, and a threaded rod 33 is fixedly mounted on the output end of the forward and reverse motor 31. One end of the threaded rod 33 passes through one side of the inner wall of the slide groove 32. A threaded sleeve 34 is threadedly connected to the outer surface of the threaded rod 33. A moving block 35 is fixedly mounted on the outer surface of the threaded sleeve 34. A push plate 36 is fixedly mounted on the upper end of the moving block 35. Two insert plates 37 are fixedly mounted on one side of the push plate 36. The forward and reverse motor 31 drives the threaded rod 33 to rotate. Due to the threaded connection between the threaded sleeve 34 and the threaded rod 33, the moving block 35 moves in the slide groove 32. The moving block 35 drives the push plate 36 and the insert plates 37 to push the workpiece on the holding platform 1 into the annealing furnace inlet, thus achieving the effect of automatic feeding, reducing manual operation, and avoiding burns to personnel.

[0031] The working principle is as follows: When using this utility model, the workpiece to be annealed is placed on the holding platform 1 by hand, and the moving cart 5 is moved to the annealing furnace inlet by pushing the push handle 6. It is fixed by the stopable moving wheels 7, thus achieving stable placement of this utility model. The lifting device 2 raises the holding platform 1 to the annealing furnace inlet, and then the pushing feeding device 3 pushes the workpiece into the annealing furnace. Overall, it reduces unnecessary manual operation and avoids the problem of personnel being burned. The adjustable height effect improves the practicality of this utility model.
