Description

Technical Field

[0001] The utility model belongs to the technical field of buffer pads, in particular to a buffer material pad for unloading aluminum alloy hot-rolled medium and thick plates. Background Art

[0002] With the continuous expansion of market demand for high-end aluminum alloy materials, the requirements for plate surface quality are becoming higher and higher. In the current national standards for aluminum alloy plates, it is allowed to polish and repair the surface defects such as scratches that do not exceed the thickness tolerance of the plate. Aluminum alloy companies do not pay much attention to the surface quality of the plate. However, more and more customers, especially aviation main engine manufacturers, have put forward strict requirements that do not allow polishing to repair plate surface defects. Such requirements are not only for the beauty of the plate surface quality, but more importantly, the damage defects on the plate surface will cause certain interference to the judgment of defects during the water immersion ultrasonic flaw detection of the plate at the back end. Therefore, the control and improvement of the surface quality of the plate is very urgent.

[0003] There are many processing steps for aluminum alloy plates, and the production process is long. There are surface quality defects such as scratches, bumps, and abrasions during the production or operation process. Therefore, each process deserves special attention, especially the hot rolling process. The hot rolling process is one of the important processes in plate production. After the plate is rolled to the finished thickness, the rolled plate needs to be unloaded from the rolling mill to the supporting material car, and each material car needs to be loaded with plates of various specifications such as different thicknesses and lengths. Each plate is usually isolated by a material pad; when the unloading device unloads the rolled plate from the rolling mill to the material car, the plate is in a free fall state, and the plate falling from the unloading device is a hard landing compared to the plate on the material car, which increases the risk of plate damage.

[0004] Although there are pads to isolate the plates, the existing pads are mainly composed of heat-resistant felt pads wrapped in aluminum foil, and the thickness of the pads is only about 10 mm, which has little cushioning effect on the hard landing of the plates. In addition, since the thickness of the pads is too thin, it is not convenient to insert a vernier caliper to measure the thickness of the plates, and it is also very inconvenient to measure the thickness of the hot-rolled plates. Therefore, how to improve the cushioning capacity of the pads and minimize the impact force caused by the falling plates is very important to avoid damage to the plates. Utility Model Content

[0005] The purpose of the utility model is to provide a cushioning pad for unloading aluminum alloy hot-rolled medium and thick plates, thereby overcoming the problems of conventional pads being too thin and having poor cushioning capacity. The specific technical solution is as follows:

[0006] A buffering material pad for unloading hot-rolled medium and thick aluminum alloy plates, characterized in that it includes a buffering pad main body, the buffering pad main body includes a first clamping part, an elastic part and a second clamping part arranged in sequence, the elastic part is bonded between the first clamping part and the second clamping part, and the buffering pad main body is used to buffer the plate material.

[0007] Preferably, the first clamping part includes a first heat-resistant felt and a first aluminum plate, and the first heat-resistant felt and the first aluminum plate are bonded by a strong adhesive.

[0008] Preferably, the second clamping part includes a second heat-resistant felt and a second aluminum plate, and the second heat-resistant felt and the second aluminum plate are bonded by a strong adhesive.

At the same time, the designed pad is thick enough to facilitate the later measurement of the panel thickness.

[0016] 3. In the present invention, the buffer pad has a double-layer heat-resistant protection function, which can not only play a good buffering effect, but also has good heat resistance and heat insulation, thereby extending the service life of the pad.

[0017] 4. In the present invention, the buffer pad is arranged in multiple layers, and the overall thickness is thicker than the existing common buffer pad, which increases the distance between the receiving plates and facilitates the subsequent measurement of the thickness of the plates.

The following is a description of the embodiments of the present invention based on its overall structure.

[0026] Example

[0027] like Figure 1 As shown, a buffer material pad for unloading hot-rolled medium and thick plates of aluminum alloy mainly includes a buffer pad body 100, wherein the buffer pad body 100 includes a first clamping portion 110, an elastic portion 120 and a second clamping portion 130 arranged in sequence, wherein the elastic portion 120 is bonded between the first clamping portion 110 and the second clamping portion 130, and the first clamping portion 110 and the second clamping portion 130 clamp the elastic portion 120 in the middle, and more preferably, the buffer pad body 100 is further wrapped with an aluminum foil layer 140, and the above-mentioned whole is wrapped by the aluminum foil layer 140 to form a buffer material pad for unloading hot-rolled medium and thick plates of aluminum alloy. The buffer pad body 100 is used to buffer the plate material. The buffer body 100 can cover the specifications of most existing aluminum alloy thick plate orders. When there is an order for extra-wide plates, the problem can be solved by increasing the number of pads. Such a pad structure can play a good buffering role for the falling plates. Even if the extra-thick plates with extremely high weight compress all the springs, the thickness of the upper and lower aluminum plates plus the felt pad itself can significantly increase the distance between the plates, which can avoid direct collision (contact) between the plates to the greatest extent, effectively reduce the quality risk of damage to the plates, and at the same time leave enough space (spacing) for measuring the thickness of the plates.

[0028] In the present invention, specifically, the first clamping part 110 includes a first heat-resistant felt 111 and a first aluminum plate 112, and the first heat-resistant felt 111 and the first aluminum plate 112 are bonded by a strong adhesive. Similarly, the first clamping part 110 and the second clamping part 130 have the same size and structure, and the second clamping part 130 includes a second heat-resistant felt 131 and a second aluminum plate 132, and the second heat-resistant felt 131 and the second aluminum plate 132 are bonded by a strong adhesive. The first heat-resistant felt 111, the first aluminum plate 112, the second heat-resistant felt 131 and the second aluminum plate 132 has the same length, width, height and shape. Here, the thickness setting size of the upper and lower aluminum plates (the first aluminum plate 112 and the second aluminum plate 132) can be: 12*50*1500mm. The first heat-resistant felt 111 and the second heat-resistant felt 131 covering the first aluminum plate 112 and the second aluminum plate 132 are the more common felt materials currently available. The size and specification of the felt are similar to the size of the upper and lower aluminum plates. The upper and lower felts can be bonded to the upper and lower aluminum plates by strong glue, or they can be directly covered on the outer end surfaces of the upper and lower aluminum plates without being connected.

[0029] Furthermore, the length and width of the elastic portion 120 are respectively smaller than the length and width of the first clamp portion 110 or the second clamp portion 130, that is, the size (length and width) of the sponge layer 121 is smaller than the size (length and width) of the first clamp portion 110 or the second clamp portion 130. The reason is that the heat resistance of the sponge layer 121 is smaller than that of the first clamp portion 110 and the second clamp portion 130. In order to avoid the sponge layer 121 being exposed to the outside and directly contacting the plate during unloading, causing the sponge layer 121 to be scorched and affecting its own performance, the overall size of the sponge layer 121 is smaller than that of the first clamp portion 110 and the second clamp portion 130.

[0030] In summary, the utility model provides a buffering pad for unloading aluminum alloy hot-rolled medium and thick plates. The buffering pad has a simple structure, is easy to process and manufacture, and has a good buffering effect, and has a great promotion significance; the buffering pad in the utility model has a built-in uniform and equidistant high-strength spring and a sponge layer, which can play a good buffering role for the falling plates. Even if the heavy super-thick plate compresses the spring and the sponge layer completely, the original thickness of the upper and lower aluminum plates and the heat-resistant felt can also significantly increase the distance between the plates, which can avoid direct contact between the plates to the greatest extent, and effectively reduce the risk of surface damage caused by collision of the plates. At the same time, the designed pad has a sufficient thickness, which can also facilitate the later measurement of the thickness of the plates; in the utility model, the buffering pad has a double-layer heat-resistant protection function, which can not only play a good buffering effect, but also has good heat resistance and heat insulation, and prolongs the service life of the pad; in the utility model, the buffering pad is arranged in multiple layers, and the overall thickness is thicker than the existing common buffering pads, which increases the distance between the receiving plates and the plates, and facilitates the later measurement of the thickness of the plates.
