Abstract
Description
Technical Field
[0001] This application belongs to the technical field of rolling equipment, and particularly relates to a disc waste shearing chute. Background Technology
[0002] The disc shear for edge trimming is one of the core pieces of equipment widely used in continuous cold-rolled strip steel production lines. It is used to cut the edges of the strip steel to achieve a set width. A scrap shear is often installed after the disc shear to cut the waste edges into smaller segments for easier handling. Between the disc shear and the scrap shear are waste edge chutes for both the disc shear and the scrap shear, guiding the waste edges smoothly into the scrap shear for cutting.
[0003] As the disc shearing waste edge chute is used for a longer period of time, it gradually wears down due to the waste edge, especially at the chute inlet.
[0004] In related technologies, when a chute wears out, the usual practice is to replace the entire chute with a disc-cut waste edge, which results in high replacement costs. Utility Model Content
[0005] This application aims to at least partially solve the technical problem in related technologies where the entire disc waste shearing chute needs to be replaced after wear, resulting in high replacement costs. Therefore, this application provides a disc waste shearing chute.
[0006] This application provides a waste edge chute for a disc shear, used to guide the waste edge generated during the shearing of strip steel by a disc shear, comprising:
[0007] A chute body having a guide channel for guiding the waste edge;
[0008] A guide block is disposed inside the entrance of the guide channel and on one side near the cutting edge of the disc shear. The guide block is detachably connected to the chute body, and the side of the guide block near the cutting edge of the disc shear has a first guide surface for guiding the waste edge.
[0009] In some embodiments, the chute body has a first limiting portion and a second limiting portion; the first limiting portion is disposed on the front side of the guide block along the extending direction of the guide channel; the second limiting portion is disposed on the front side of the guide block along the width direction of the guide channel; the guide block is in contact with both the first limiting portion and the second limiting portion, and the guide block is detachably connected to the second limiting portion.
[0010] In some embodiments, the guide block extends out of the first limiting portion in the opposite direction to the width direction.
[0011] In some embodiments, the guide block and the second limiting portion are detachably connected by bolts.
[0012] In some embodiments, the guide block further has a second guide surface, and the chute body further has a vertically arranged third guide surface and a fourth guide surface, the second guide surface being flush with the third guide surface; the second guide surface, the third guide surface and the fourth guide surface are all disposed outside the guide channel, and are all used to guide the edge of the remaining part of the strip steel.
[0013] In some embodiments, the chute body includes a chute body and a chute cover assembly. The chute body is detachably connected to the guide block. The chute body has an upward-facing groove. The chute cover assembly is disposed above the chute body and detachably connected to the chute body, so that the chute body and the chute cover assembly enclose the guide channel.
[0014] In some embodiments, the slot cover assembly includes a front cover and a rear cover, the front cover being disposed on the side near the inlet of the guide channel and the rear cover being disposed on the side near the outlet of the guide channel, both the front cover and the rear cover being detachably connected to the slot body.
[0015] In some embodiments, the inner walls of the front cover and the rear cover are respectively provided with a first guide groove and a second guide groove extending along the length direction of the groove body.
[0016] In some embodiments, the bottom wall of the first guide groove is arc-shaped.
[0017] In some embodiments, the disc waste shearing chute further includes a tail stop, which is detachably connected to the chute body and at least a portion of the tail stop is located on the front side of the chute body along the extension direction of the guide channel.
[0018] This utility model has at least the following beneficial effects:
[0019] The side of the guide channel entrance closest to the shear blade is the first to come into contact with the waste edge and is more prone to wear. By placing the guide block inside the guide channel entrance, close to the shear blade of the disc shear, and detachably connecting the guide block to the chute body, the guide block can wear in place of the chute body. When the guide block is severely worn, it can be removed from the chute body and replaced with a new one. This eliminates the need to replace the entire disc shear waste edge chute, helping to reduce maintenance costs and thus lower strip steel production costs. Furthermore, this design allows for the guide block to be made of a wear-resistant material, such as high-manganese steel, instead of the entire disc shear waste edge chute being made of the same material, further reducing manufacturing costs.

[0031] In related technologies, there is a technical problem that disc shearing waste edge chutes need to be replaced entirely after severe wear. This application provides a disc shearing waste edge chute that can at least partially solve the technical problem of needing to replace the entire disc shearing waste edge chute after severe wear.
[0032] This application is described below with reference to the accompanying drawings and specific embodiments:
[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the waste edge chute 100 of the disc shear 200 is used to guide the waste edge generated by shearing the strip steel 300 by the disc shear 200, and includes a chute body 110 and a guide block 120. The chute body 110 has a guide channel 110c for guiding the waste edge. The guide block 120 is disposed in the inlet 110d of the guide channel 110c and near the shearing blade 210 of the disc shear 200. The guide block 120 is detachably connected to the chute body 110, and the side of the guide block 120 near the shearing blade 210 of the disc shear 200 has a first guide surface 120a for guiding the waste edge.
[0034] The chute body 110 guides the waste edge through the guide channel 110c. The guide channel 110c has a connected inlet 110d and outlet 110e. After the waste edge is sheared off from the strip 300, it enters the guide channel 110c through the inlet 110d and exits through the outlet 110e. The outlet 110e of the guide channel 110c is aligned with the inlet of the waste edge chute of the scrap shear. After the waste edge is discharged from the outlet 110e of the guide channel 110c, it enters the waste edge chute of the scrap shear and, guided by the waste edge chute, enters the scrap shear for shearing.
[0035] The first guide surface 120a on the guide block 120 guides the waste edge. The first guide surface 120a is an inclined surface, which allows the waste edge to smoothly enter the guide channel 110c under the action of the first guide surface 120a.
[0036] The side of the inlet 110d of the guide channel 110c closest to the shear blade 210 is the first to come into contact with the waste edge and is more prone to wear. The guide block 120 is positioned within the inlet 110d of the guide channel 110c, close to the shear blade 210 of the disc shear 200, and is detachably connected to the chute body 110. This allows the guide block 120 to replace the worn chute body 110. When the guide block 120 is severely worn, it can be removed from the chute body 110 and replaced with a new one. This eliminates the need to replace the entire disc shear waste edge chute 100, reducing maintenance costs and thus lowering the production cost of the strip steel 300. Furthermore, with this design, only the guide block 120 can be made of a material with good wear resistance, such as high manganese steel, instead of making the entire disc waste shearing chute 100 made of a material with good wear resistance, which also reduces the manufacturing cost of the disc waste shearing chute 100.
[0037] It should be noted that during use, the disc shear waste edge chute 100 is mounted on the disc shear 200. In some embodiments, the disc shear waste edge chute 100 further includes a connector 130 fixedly connected to the chute body 110, which is used to connect with the disc shear 200. In some embodiments, the connector 130 is bolted to the outer shell of the disc shear 200.
[0038] You can refer to this. Figure 4 As shown, in some embodiments, the chute body 110 includes a chute body 111 and a chute cover assembly 115. The chute body 111 is detachably connected to the guide block 120. The chute body 111 has an upward-facing groove 111a. The chute cover assembly 115 is disposed above the chute body 111 and is detachably connected to the chute body 111, so that the chute body 111 and the chute cover assembly 115 enclose a guide channel 110c.
[0039] The groove 111a has an upward-facing opening, and the guide block 120 is disposed within the groove 111a, specifically on the side of the groove 111a closest to the cutting blade 210 of the disc shear 200. A groove cover assembly 115 covers the groove 111a, concealing its opening, thus forming a guide channel 110c with the groove body 111 and the groove cover assembly 115 together. This design allows the groove cover assembly 115 to be removed from the groove body 111 when waste edges become stuck in the guide channel 110c, facilitating the removal of obstructed waste edges by the user.
[0040] In some embodiments, the slot cover assembly 115 includes a front cover 116 and a rear cover 117. The front cover 116 is disposed on the side near the inlet 110d of the guide channel 110c, and the rear cover 117 is disposed on the side near the outlet 110e of the guide channel 110c. Both the front cover 116 and the rear cover 117 are detachably connected to the slot body 111.
[0041] The slot cover assembly 115 comprises two parts: a front cover 116 and a rear cover 117, which are designed as separate units, facilitating the machining of the slot cover assembly 115. In addition, if either the front cover 116 or the rear cover 117 is severely worn, only the severely worn one needs to be replaced, without having to replace the other, which helps reduce the maintenance cost of the disc waste shearing chute 100.
[0042] You can refer to this. Figure 2 and Figure 3 As shown, in some embodiments, the inner wall of the chute body 110 has a first limiting part 112 and a second limiting part 113; along the extending direction of the guide channel 110c, the first limiting part 112 is disposed on the front side of the guide block 120; along the width direction of the guide channel 110c, the second limiting part 113 is disposed on the front side of the guide block 120; the guide block 120 is in contact with both the first limiting part 112 and the second limiting part 113, and the guide block 120 is detachably connected to the second limiting part 113.
[0043] Along the width direction of the guide channel 110c, a second limiting part 113 is disposed on the front side of the guide block 120, and the second limiting part 113 limits the second limiting part 113 in the width direction of the guide channel 110c. After the waste edge is cut from the strip 300, it will continue to move forward under the drive of the strip 300, and the waste edge will exert a pushing force on the guide block 120 along the extension direction of the guide channel. In these embodiments, by disposing the first limiting part 112 on the front side of the guide block 120 and contacting the guide block 120, the first limiting part 112 can provide support force to the guide block 120 in the opposite direction of the extension direction. This design can reduce the requirement for the connection strength between the guide block 120 and the second limiting part 113, and help ensure the stability of the guide block 120 in the extension direction of the guide channel 110c.
[0044] In some embodiments, the groove 111 has a first limiting portion 112 and a second limiting portion 113.
[0045] The second limiting part 113 and the guide block 120 can be detachably connected in various ways, such as by snap-fit or adhesive bonding. In some embodiments, the guide block 120 and the second limiting part 113 are detachably connected by bolts. The second limiting part 113 has a relief through hole for the bolt, and the guide block 120 has a threaded hole for threaded engagement with the bolt. The bolt passes through the relief through hole and engages with the threaded hole. Connecting the guide block 120 and the second limiting part 113 by bolts facilitates the separation of the guide block 120 and the second limiting part 113 while ensuring the connection strength between the guide block 120 and the second limiting part 113.
[0046] like Figure 3 As shown, in some embodiments, the guide block 120 extends out of the first limiting portion 112 in the opposite direction to the width direction of the chute body 110. As the waste edge moves forward along the extension direction of the guide channel 110c, if the inner wall of the guide channel 110c has a protrusion, the end of the waste edge is prone to impacting the protrusion, easily causing the waste edge to become stuck. Along the extension direction of the guide channel 110c, since the first limiting portion 112 is located in front of the guide portion, these embodiments design the guide block 120 to extend out of the first limiting portion 112 to prevent the end of the waste edge from impacting the first limiting portion 112 during transmission, thus helping to ensure that the waste edge passes smoothly through the guide channel 110c.
[0047] like Figure 1 As shown, in some embodiments, the guide block 120 also has a second guide surface 120b, and the chute body 110 also has a vertically arranged third guide surface 110a and a fourth guide surface 110b, with the second guide surface 120b flush with the third guide surface 110a; the second guide surface 120b, the third guide surface 110a and the fourth guide surface 110b are all located outside the guide channel 110c, and are all used to guide the edges of the remaining portion of the strip steel 300.
[0048] The second guide surface 120b and the third guide surface 110a are flush, and the third guide surface 110a is perpendicular to the fourth guide surface 110b. With this design, the lower surface of the edge of the remaining part of the strip 300 after it is sheared can be guided by the second guide surface 120b and the third guide surface 110a, and the side can be guided by the fourth guide surface 110b. This will help ensure that the remaining part of the strip 300 is transported forward smoothly.
[0049] In some embodiments, the front pressure cover 116 has a fourth guide surface 110b, and the chute body 110 has a third guide surface 110a.
[0050] In some embodiments, when the disc shear waste edge chute 100 is installed on the disc shear 200, the second guide surface 120b and the third guide surface 110a are both parallel to the horizontal plane.
[0051] The scrap shear is 200mm lower than the disc shear. This is to guide the scrap edges to the scrap shear, such as... Figure 6 As shown, when the waste edge chute 100 of the disc shear is installed on the disc shear 200, the guide channel 110c is inclined downwards; specifically, one end of the inlet 110d is higher, and one end of the outlet 110e is lower. The strip steel 300 is transported horizontally to the disc shear 200, and because the strip steel 300 has a certain degree of toughness, the waste edge will contact the inner walls of the front pressure cover 116 and the rear pressure cover 117 when it is transported forward. Figure 5 As shown, in some embodiments, the inner walls of the front pressure cover 116 and the rear pressure cover 117 are respectively provided with a first guide groove 116a and a second guide groove 117a extending along the length direction of the groove body 111. With this design, the side walls of the first guide groove 116a and the second guide groove 117a can limit the side walls of the waste edge, so that the waste edge is limited between the two side walls of the first guide groove 116a and the two side walls of the second guide groove 117a, which helps to make the waste edge move smoothly.
[0052] In some embodiments, the bottom wall and side wall of the first guide groove 116a and the bottom wall and side wall of the second guide groove 117a are smoothly transitioned. The sharp corners of the scrap edge are right angles, and the smooth transition design helps to reduce the contact area between the sharp corner area of the scrap steel and the first guide groove 116a and the second guide groove 117a, thereby reducing friction and ensuring smooth movement of the scrap edge.
[0053] In some embodiments, the bottom wall of the first guide groove 116a is arc-shaped. Since the guide channel 110c guides the strip steel 300 downward, the section of scrap steel below the front pressure cover 116 bends into an arc shape. Designing the bottom wall of the second guide groove 117a to be arc-shaped corresponds to the natural deformation trajectory of the strip steel 300 when it bends, which helps to ensure that the two side walls of the bent section of the scrap edge are located between the two side walls of the second guide groove 117a.
[0054] A disc shear waste edge chute 100 and a waste edge shear waste edge chute are provided between the disc shear 200 and the waste edge shear, both chutes being used to guide the waste edge. If there is a gap between the outlet 110e side of the disc shear waste edge chute 100 and the inlet side of the waste edge shear waste edge chute, the end of the waste edge can easily pass through the gap. However, in actual installation, due to installation errors and other factors, there is usually a certain gap between the outlet 110e side of the disc shear waste edge chute 100 and the inlet side of the waste edge shear waste edge chute. Therefore, if... Figure 4 As shown, in some embodiments, the disc shear waste edge chute 100 further includes a tail stop 140, which is detachably connected to the chute body 110. At least a portion of the tail stop 140 is located on the front side of the chute body 110 along the extending direction of the guide channel 110c. When the disc shear waste edge chute 100 is installed on the disc shear 200, the tail stop 140 is located between the chute body 110 and the waste edge chute, filling the gap between them and thus reducing the risk of the waste edge end protruding between the chute body 110 and the waste edge chute to a certain extent. The tail stop 140 is detachably connected to the chute body 110, allowing for replacement with a tail stop 140 of the appropriate size according to the specific gap value between the chute body 110 and the waste edge chute, thus facilitating user operation.
[0055] There are various ways to detachably connect the tail stop 140 and the chute body 110, such as bolt connection, snap-fit connection, etc.
[0056] In some embodiments, two tail stops 140 are provided, which are arranged opposite to each other along the width direction of the guide channel 110c and are respectively installed on both sides of the chute body 110.
[0057] like Figure 3 As shown, in some embodiments, the tailgate 140 is generally L-shaped, including a connecting portion 141 and a filling portion 142. The connecting portion 141 and the filling portion 142 are perpendicular, and one end of the connecting portion 141 is fixedly connected to one end of the filling portion 142. The connecting portion 141 is bolted to the groove 111, and the filling portion 142 is located on the front side of the groove 111.
[0058] The working principle of the disc waste shearing chute 100 is described below:
[0059] The disc shear waste edge chute 100 is installed on the disc shear 200. After installation, the gap between the outlet 110e side of the disc shear waste edge chute 100 and the inlet side of the waste edge chute is measured. Based on the gap, a tail stop 140 of appropriate size is selected and bolted to the trough body 111 to fill the gap between the chute body 110 and the waste edge chute. When the disc shear 200 is running, the edge of the strip steel 200 is sheared by the shear blade 210. The side of the waste edge will contact the first guide surface 120a. Under the guidance of the first guide surface 120a, the waste edge enters the guide channel 110c and will be located between the two side walls of the first guide groove 116a and the two side walls of the second guide groove 117a. The side walls of the first guide groove 116a and the second guide groove 117a limit the waste edge, and the waste edge is finally discharged from the outlet 110e. If the guide block 120 is severely worn, remove the guide block 120 from the groove 111 and install a new guide block 120. If the front cover 116 is severely worn, remove the front cover 116 from the groove 111 and install a new front cover 116. If the rear cover 117 is severely worn, remove the rear cover 117 from the groove 111 and install a new rear cover 117. If the waste edge cannot move forward and is stuck in the guide channel 110c, remove the front cover 116 and the rear cover 117 to release the obstruction, and then install the front cover 116 and the rear cover 117 back into the groove 111.
