Description

Technical Field

[0001] The utility model belongs to the technical field of trimming shear chutes, in particular to a trimming shear scrap material chute. Background Art

[0002] The trimming shear is used in the cold-rolled and hot-rolled steel coil opening and shearing line. The metal coil is unrolled, leveled, cut to length, and sheared into the required length of flat plates and stacked. The sheared edge wire enters the chute. The current design of the trimming shear chute solves the problem of edge wire entering the chute, but it must be based on the premise of absolute stability without any abnormalities. There are many variable factors in the daily production process, such as the instability of trimming allowance, changes in equipment status and speed changes, which will cause edge blocking problems in the production process.

[0003] After the trimming wire enters the scrap chute, the upper and lower sides of the chute are the parts that are subject to the greatest force and are also the most easily damaged. After blocking the edge, the only way to remove the chute is to remove the upper cover plate. Since the upper cover plate has a certain weight and is fixed with multiple countersunk screws, it is difficult and time-consuming to remove. Severe blocking may even cause the upper cover plate to deform and the chute to be scrapped. Utility Model Content

[0004] The utility model aims to provide a trimming and shredding chute to solve the problems in the prior art.

[0005] Provided is a trimming and scrapping chute, comprising:

[0006] The chute body, the top cover plate, the bottom cover plate and at least one side wall cover plate of the chute body are integrally formed to form a U-shaped side trough, and the side wall of the chute body is different from the U-shaped side trough and is provided with an opening and closing plate, and the opening and closing plate is detachably connected to the U-shaped side trough.

[0007] Furthermore, the opening and closing plate is hinged to one connecting edge of the U-shaped side groove via a plurality of hinge parts, and the opening and closing plate is detachably connected to the other connecting edge of the U-shaped side groove via a plurality of locking pin parts.

[0008] Furthermore, it also includes a pad, a groove is opened on the side wall of the opening and closing plate, the pad is fixedly connected in the groove by a plurality of countersunk screws, and the top of the pad extends 2mm to 4mm relative to the side wall of the opening and closing plate.

[0009] Furthermore, the material used for the cushion block is plastic.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] Since the upper and lower surfaces of the chute are the main stress-bearing surfaces, the top cover plate and the bottom cover plate of the chute are connected as a whole through the U-shaped side grooves, which enhances the structural strength of the top cover plate. When the opening and closing plates are closed, the chute works normally to transport trimmed and scrapped materials. When the chute is blocked, the opening and closing plates can be opened to clear the inside, reducing the difficulty of loading and unloading the chute. The improved chute reduces the difficulty of maintenance and significantly increases its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 As shown, in an embodiment of the utility model, a trimming and shearing chute includes a chute body 1, and the top cover plate, the bottom cover plate and at least one side wall cover plate of the chute body 1 are integrally formed to form a U-shaped side trough 11, and the side wall of the chute body 1 which is different from the U-shaped side trough 11 is provided with an opening and closing plate 12, and the opening and closing plate 12 and the U-shaped side trough 11 are detachably connected.

[0019] The original chute design has an upper cover plate, which is fixed with screws. Once the chute is blocked, the upper cover plate will be severely deformed and the screws will break, which is extremely inconvenient to deal with. Since the U-shaped side trough 11 is integrally formed, the top cover plate and the two side walls are no longer fixed with countersunk screws, which improves the overall structural strength of the chute and the deformation resistance of the top cover plate. When the chute is blocked, the opening and closing plate 12 can be opened from the side wall of the chute, which reduces the difficulty of disassembly of the chute and improves the maintenance efficiency.

[0020] The opening and closing plate 12 is hinged to one connecting edge of the U-shaped side groove 11 through a plurality of hinge parts 2, so that the opening and closing plate 12 can rotate relative to the U-shaped side groove 11. The opening and closing plate 12 is detachably connected to the other connecting edge of the U-shaped side groove 11 through a plurality of lock pin parts 3, and the lock pin parts 3 cooperate with the latch through the lock buckle. When the chute works normally, the latch of the lock pin part 3 is located in the lock buckle, which plays a role of fixing and bearing force. When the chute is blocked, the latch is pulled out and the opening and closing plate 12 is rotated to open the chute.

[0021] Furthermore, the chute also includes a pad 4. After trimming, the edge of the steel plate is placed on the opening and closing plate 12 of the chute. The steel-to-steel contact between the original steel plate and the opening and closing plate 12 is prone to scratches and wear, so the pad 4 is provided as a structural transition. A groove 121 is provided on the side wall of the opening and closing plate 12, and the pad 4 is fixedly connected to the groove 121 by a number of countersunk screws, so that the pad 4 is stably fixed on the opening and closing plate 12 and in contact with the steel plate. The top of the pad 4 extends a distance of 2mm to 4mm relative to the side wall of the opening and closing plate 12, so that the pad 4 can fully contact the steel plate and provide space for the pad 4 to be worn and consumed.

[0022] The material used for the cushion block 4 is plastic, which reduces the scratching degree of the cushion block 4 on the steel plate and ensures the quality of the steel plate product.

[0023] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
