Description

Technical Field

[0001] This utility model relates to the field of steel processing, and in particular to a hydraulic shear with a waste ejection device. Background Technology

[0002] The inner ring of the raw material in the continuous production line of cold rolled stainless steel has the coiling creases from the previous coiling machine. The inner ring (i.e. the tail) of the raw material needs to be cut off when uncoiling. The current continuous stainless steel production line uses hydraulic shears to cut the tail. The pinch rollers clamp the waste material and first send out a section of waste material in the air. When the waste material leaves the pinch rollers, it tilts and falls into the waste hopper by its own weight.

[0003] The existing pinch roller driven waste conveying mechanism described above has the following problems: the tail waste needs to be sheared long enough for it to successfully fall into the waste hopper. This method of conveying waste via pinch rollers results in raw material waste and affects the yield of the sheet material. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic shear with a waste ejection device, which improves the yield of sheet metal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic shear with a scrap ejection device, the hydraulic shear being used to cut scrap from steel coils, the scrap being transported to the hydraulic shear by a clamping roller, comprising: a pallet for supporting the scrap; a shearing device capable of cutting the scrap on the pallet; and an ejection device located below the pallet, the output end of the ejection device extending from the pallet and lifting the cut scrap, thereby causing the cut scrap to slide off the pallet.

[0006] Furthermore, the shearing device includes an upper shear blade and a lower shear blade, the upper shear blade being located above the pallet, and the lower shear blade and the clamping roller being located on both sides of the pallet.

[0007] Furthermore, the upper surface of the lower shear blade and the upper surface of the support plate are located on the same plane.

[0008] Furthermore, the pallet is provided with an opening, and the output end of the ejector device can pass through the opening to lift the waste material.

[0009] Furthermore, the opening is located at the center of the tray.

[0010] Furthermore, it also includes a waste hopper located on the side of the pallet away from the pinch roller.

[0011] Furthermore, the ejection device includes a cylinder.

[0012] Analysis shows that this utility model discloses a hydraulic shear with a waste ejection device. This utility model allows for more flexible setting of the shearing length for the waste portion of the steel coil. The shortest shearing length can be equal to the distance between the pinch roller and the lower shear blade, reducing steel coil waste and improving yield. It solves the problem of waste failing to fall into the waste hopper due to insufficient shearing length. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0019] The accompanying drawings illustrate one or more examples of the present invention. The detailed description uses numerals and letters to refer to features in the drawings. Similar or analogous reference numerals in the drawings and description have been used to refer to similar or analogous parts of the present invention. As used herein, the terms “first,” “second,” “third,” and “fourth,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of a single component.

[0020] like Figures 1-2 As shown, according to an embodiment of the present invention, a hydraulic shear with a waste ejection device 2 is provided. The hydraulic shear is used to cut waste from steel coils 7. The waste is transported to the hydraulic shear by a clamping roller 1. The shear includes: a pallet 3 for supporting the waste; a shearing device capable of cutting the waste on the pallet 3; and an ejection device 2 located below the pallet 3. The output end of the ejection device 2 can extend from the pallet 3 and lift the sheared waste, thereby causing the sheared waste to slide off the pallet 3.

[0021] The aforementioned pinch roller 1 can clamp the scrap portion of the steel coil 7 onto the pallet 3. Typically, the height of the discharge port of the pinch roller 1 is the same as the height of the upper surface of the pallet 3, thereby ensuring that the scrap can be conveyed to the pallet 3 in a horizontal manner.

[0022] The distance between the pallet 3 and the pinch roller 1 is at most 3mm-10mm. The function of the pallet 3 is to lift the steel coil 7 so that the steel coil 7 can reach the shearing position smoothly. The gap is generally 3-10mm, that is, the pallet 3 cannot touch the pinch roller 1 to avoid the pinch roller 1 rotating and scratching the roller surface. The gap should not be too wide to prevent the strip from passing through the gap and going under the pallet 3.

[0023] The ejection device 2 described above can contact the waste material at its output end during ejection, thereby raising the side of the waste material close to the pinch roller 1. Since the waste material is tilted after being raised, it is not necessary to suspend part of the waste material so that the waste material can slide down.

[0024] The shearing device includes an upper shear blade 4 and a lower shear blade 5. The upper shear blade 4 is located above the pallet 3, and the lower shear blade 5 and the clamping roller 1 are located on both sides of the pallet 3. During the shearing operation, the lower shear blade 5 moves upward, and the upper and lower shear blades 5 form a cutting edge to cut the steel coil 7.

[0025] The upper surface of the lower shear blade 5 and the upper surface of the support plate 3 are located on the same plane.

[0026] The pallet 3 has an opening, and the output end of the ejector device 2 can pass through the opening to lift the waste material.

[0027] By setting an opening, the output end of the ejector device 2 can pass through the tray 3. At the same time, the opening will not affect the load-bearing capacity of the tray 3. The tray 3 can still carry waste material after the opening is set.

[0028] The opening is located at the center of the support plate 3.

[0029] The dimensions of the aforementioned tray 3 can be 1640mm*150mm*15mm, and the diameter of the opening can be 100mm. This aperture allows the ejector device 2 to pass through without affecting the use of the tray 3.

[0030] The aforementioned opening is usually located at the center of the pallet 3. In actual use, the position of the opening can be changed according to the requirements. The opening should be set so that the ejector device 2 can lift the waste material.

[0031] It also includes a waste hopper 6, which is located on the side of the pallet 3 away from the pinch roller 1.

[0032] The aforementioned waste hopper 6 can directly receive waste material that slides down from the hydraulic shear, thereby realizing the recycling of waste material.

[0033] The ejection device 2 includes a cylinder, which occupies a small space and can make full use of the narrow space between the hydraulic shears and the pinch rollers 1.

[0034] The cylinder model mentioned above is SC32*600-S, with a stroke of 600mm, a retracted length of 740mm, a fully extended length of 1293mm, an air pressure of 0.6Mpa, and a thrust of 45KN.

[0035] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: This utility model can more flexibly set the shearing length of the scrap portion of the steel coil 7, and can shear the scrap to a length equal to the distance between the pinch roller 1 and the lower shear blade 5, reducing the waste of steel coil 7 and improving the yield. It solves the problem that the scrap cannot fall into the scrap hopper 6 due to insufficient shearing length.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
