Scrap Chute having Cylinder Protection Function
[14] The present invention relates to a scrap chute attached to the body of the skin cut mill upcut shear device and guides the cut scrap to the scrap box while performing a lifting operation, and more particularly, protects the cartridge clamp cylinder exposed during the knife lift with a protective plate. The present invention relates to a scrap chute having a cylinder protection function which can prevent the hydraulic piping of the equipment from being broken.
[15] In general, the scrap chute 1 is installed under the fixed scrap guide plate 7 of the knife 4 to guide the scrap 8 cut by the knife 4 into a scrap box (not shown). In this up cut shear device, the cartridge clamp cylinder 6 attached to the lower portion of the scrap guide plate 7 is exposed between the scrap chute 1 and the scrap guide plate 7 when the knife 4 is raised.
[16] In order to continue the mailing operation while replacing the scrap box filled with the cut scrap 8 with an empty scrap box, a specimen table (not shown) for feeding a strip is introduced to cut the scrap scrap on the specimen table. As the position of is just below the scrap chute 1, cutting several scraps causes the cut scrap 8 to span the scrap chute 1 as shown in FIG.
[17] In this case, when the knife 4, which was automatically operated, descends, the end of the scrap 8 spanning the scrap chute 1 is caught between the scrap chute 1 and the scrap guide plate 7, and the scrap When the guide plate 7 presses the scrap 8 and the scrap chute 1, the scrap chute 1 is damaged. At this time, the knife chute 5 is bent while the scrap chute 1 is installed in an inclined direction. It will damage the cartridge clamp cylinder (6) attached to it and the hydraulic pipe nearby.
[18] For this reason, the operator feels considerable anxiety when cutting the specimen scrap by inserting the specimen table and frequently stops the equipment to prevent accidents even in the slightest. At this time, clamp and pipe connection to fix the pipe by vibration of the hydraulic pipe If the flange fixing bolt is loosened and hydraulic oil is leaked, and the scrap chute (1) and cartridge clamp cylinder (6) are damaged, the skin pass mill cannot work and the broken scrap chute (1) and cartridge clamp There was a problem that a lot of time and manpower should be mobilized to replace and maintain the cylinder (6).
[19] The present invention has been invented to solve the above problems, and even if the cut scraps are spread across the scrap chute so that there is no phenomenon between the scrap guide plate and the scrap chute to prevent equipment accidents to reduce the downtime of the facility and It is an object of the present invention to provide a scrap chute with a cylinder protection function to reduce the psychological anxiety of the operator.

[20] In order to achieve the above object, a scrap chute having a cylinder protection function according to the present invention is automatically coupled to a scrap guide plate attached to the scrap guide plate to guide the scrap cut by the lifting knife to the scrap box. In the chute, a support is formed vertically at the top, and a connecting plate is formed perpendicular to the support and parallel to the scrap guide plate to be coupled to the scrap guide plate, and a hinge connection is formed at the center of the front part to include a protection plate. The hinge portion of the protective plate is characterized in that the end is hinged.
[21] Hereinafter, a scrap chute having a cylinder protection function according to the present invention will be described with reference to the accompanying drawings.
[22] As shown in Figs. 3 and 4, the scrap chute having a cylinder protection function includes the scrap chute 10, the chute pedestal 30 and the protection plate 50 as main components.
[23] The protective plate 50 is fastened to a through hole formed in the scrap guide plate 7 fixed to the upper portion of the knife body 5 by using the connecting plate 70 coupled to the upper end of the protective plate 50.
[24] The support plate 60 is provided at an upper portion of the protection plate 50 at a right angle with the protection plate 50, and a connection plate 70 is provided on the side surface of the support plate 60 in parallel with the scrap guide plate 7. Support 60 is provided at a right angle to the protective plate 50 on the upper portion of the protective plate 50, the groove is formed so that the lower end of the scrap guide plate (7) can be inserted. Connection plates 70 are provided at right and left sides of the grooves formed in the support 60 in a vertical direction with the support 60. In order to fasten the connecting plate 70 and the scrap guide plate 7, a through hole is formed in the center of the connecting plate 70 and the scrap guide plate 7, and fastening means such as bolts, nuts, and rivets are provided in the through hole. It is fastened by using.
[25] In order to maintain the shape of the protection plate 50 and the support 60 against the external force and to reinforce the strength, the reinforcement plate 80 may be added to the rear surface of the protection plate 50 and the lower surface of the support 60.
[26] The protection plate 50 is formed at the lower portion of the scrap guide plate 7 so that the hydraulic cylinder and the hydraulic circuit, which are means for providing power required for the operation of the knife 4, are not exposed to the outside. Located.
[27] The scrap chute 10 is hingedly connected to the front surface of the protective plate 50. A hinge connection portion 40 is formed at the center of the front portion of the protective plate 50 and a hinge connection portion is formed at the end of the scrap chute 10 so that the scrap chute 10 and the protection plate 50 are hinged.
[28] The chute butt 30 is formed in the front portion of the protective plate 50, so that the scrap chute 10 can maintain a constant angle. The chute pedestal 30 is vertically formed on the protection plate 50 at the lower end of the hinge connection portion 40 formed on the front surface of the protection plate 50. The side surface of the chute butt 30 is formed to have a predetermined angle, so that the lower surface of the scrap chute 10 hinged to the protective plate 50 is located at the side surface of the chute pedestal 30 so that the chute pedestal ( 30).
[29] Referring to the operation of the scrap chute having a cylinder protection function of the present invention having the configuration as described above are as follows.
[30] A protection plate 50 is formed below the scrap guide plate 7, and the scrap chute 10 is connected to the protection plate 50, thereby providing a hydraulic cylinder that is a means for providing power required for the operation of the knife 4. The hydraulic circuit is not exposed to the outside, it is located on the rear of the protective plate (50).
[31] Therefore, since the scrap cut by the operation of the knife 4 is passed to the scrap box through the front portion of the protective plate 50 and the scrap chute 10, the scrap cut by the knife is scrapped in the process of being contained in the scrap box. Due to the insertion between the guide plate and the scrap chute 10, the operation of the hydraulic cylinder and the hydraulic circuit does not interfere or break.
[32] Scrap chute with a cylinder protection function of the present invention having the configuration and action as described above is prevented damage to the scrap chute and cartridge clamp cylinder due to the cutting scrap caught in the scrap chute of the up-cut shear device, the operator's safety accident It can prevent and reduce the psychological feeling of worker.
[33] In addition, since the space of the up cut shear device is secured to provide a wide working space during maintenance, and can be easily disassembled and combined, the effect of shortening the maintenance time is obtained.
