Description of the Invention: [Technical Field] The present invention relates to a kick plate structure of a high-speed end-cutting machine, in particular, a kick plate structure of a high-speed end-cutting machine used in a hot rolling process of steel. [Prior Art] Figure 1 shows a conventional steel hot-rolled end-cutting machine (1 00), which is a crude steel embryo cast from iron sand raw material in the hot rolling process of steel, heated to recrystallize After the temperature, it is sent to the rolling mill for rolling. When the hot rolled steel is transferred from the conveying path to the end cutting machine, the end cutting end or the leading end can be controlled by the left and right movement of the conveying path (1). The end-cutting end mainly cuts the length of the hot-rolled steel head end (5) by the cutter of the end-cutting machine (4) and falls into the waste guide groove (3), and then the lower kick plate (8) The subsequent hot-rolled steel (7) is kicked to the conveying guide to the finishing mill' and the tail section (9) of the hot-rolled steel is cut by the cutter (4) and kicked by the upper kick plate (6) to the waste guide ( Small because the ends of the steel through the thick dryer will encounter the equipment and rubbing friction during the travel, so it is easy to cause the steel clamp (4) (4), causing the subsequent process of the bag to dry or bad quality. Also, the relative low temperature point of the whole steel is required. Before it is put into the finishing machine, it needs to be cut off by the machine to enter the 201201988. Under the requirement of the yield, it is necessary to reduce the amount of cutting at both ends of the head and tail to reduce the waste generation and improve the efficiency. However, if the scraped scrap steel is too short, it is easy for the scrap steel to bounce through the kick plate, which will affect the subsequent steel travel and cause the plug. Therefore, how to properly reduce the amount of cuts at both ends of the head and tail, and maintain the process stability. Sex is an important issue.

The upper and lower kick plates of the conventional end-cutting machine are symmetrical kick plates (1〇). The problem of such punching is to cut off the tail end (9) of the hot-rolled steel: two points, as short as - fixed length Occurs when. Because the length of the upper kick plate is designed to kick the tail length of the fixed length to the waste guide groove (3), when the tail end (7) of the hot dry steel by the cutter is too short: the length of the upper upper kick plate The design will cause the tail end (9) of the too short hot dry steel to receive a downward unbalanced thrust. This force acts on the rear end of the center of gravity of the steel so that the front end of the steel bounces. The steel # cannot be fully predicted. The direction of travel may be;, the wheel guide channel (7), and even affect the subsequent fine milk process: corpse, easy to crush the slag crushing of the finishing mill; it is also possible that the hot rolled steel = (9) is not kicked to the waste guide Slot (3), staying in the process station = Benxin station material, requires the entire line of maintenance downtime and labor costs. Therefore, how to improve the kicking plate 201201988, and the structure can appropriately reduce the amount of cuts at both ends of the head and tail, and maintain the stability of the process, which is an important issue in the hot rolling process of steel. [Invention] The object of the invention is to provide a kick plate structure of a high-speed end-cutting machine to reduce the cut scrap steel and stabilize the end cutting mechanism. In order to achieve the above object, the present invention has the shape of the upper kick plate and the lower kick plate. Ten is asymmetrical, wherein the length of the upper kick plate is less than the length of the lower kick plate, but the upper kick plate is the same as the lower kick plate, as shown in the end kicker structure of Figures 3 and 4. The length of the kick plate is WF, and the length of the steel end of the end cut is about 9_〇Cm, but the invention shortens the length of the upper kick plate by about two cents - after the steel tail The end cut length is reduced to about "cm", so that the scrap material of @3〇% can be reduced to achieve the result of energy saving (4). It should be noted that 'the kick plate (1) above the invention needs to be able to kick the shortened steel tail (24) Before the center of gravity, that is, the length of the upper kick plate (15) should be less than the length of the steel tail (24) after the shortening - eight to - to ensure that the steel tail (24) does not bounce: Cutting off the scrap steel and stabilizing the end cutting mechanism.

The end cutting machine of the present invention comprises an upper rotating shaft (11), a lower rotating shaft (丨2), a rotating arm (13) connected to the upper rotating shaft, and a rotating arm (14) connected to the lower rotating shaft. A kicking plate (15) above the front end of the upper arm, a kicking plate (1 6) below the front end of the lower cantilever, and a cutter between the upper and lower arms (1Ό' additionally at the rear end of the end cutting machine (300) A guide channel (丨8) for receiving the end-cut hot-rolled steel strip and a waste guide groove (19) for receiving the scrap steel strip are provided, and a conveyor lane is provided in front of the end-cutting machine (3〇〇) (20) 'The steel (21) passing through the roughing mill is sent to the front of the end cutting machine by the conveying path (20). This conveying path (2〇) can control the forward direction of the steel (21) to the left or to the right. To determine the end of the steel to cut the end or the end. When the hot end of the steel to be cut (22) passes through the cutter (17) will be cut off and dropped into the waste guide (19), hot rolled steel # The middle section (23) is then kicked by the lower kick plate (10) to the rear guide groove (18). When the hot rolled steel tail (24) to be cut passes through the cutter (17), it is cut and falls into the waste guide groove (10). Refer to Figure 1 and Figure 2 The structure of the kick-off board (6) and the lower kick board (8) above the conventional end-cutting & knives is symmetrical.

When the length of the cut copper (9) is shortened to about 9〇cm, the sheet is fine (6) and can be kicked to the steel $201201988: (9) Center of gravity Before, so you can kick the steel tail (7) down to the *枓 guide groove (3); but when you want to cut the steel tail (9) to a length of less than 9〇cm, such as 6〇c again,,,,, The occurrence of the upper kick plate (2) after kicking the center of gravity of the steel (9) will cause the end of the steel tail to bounce. After the steel bounces, it cannot fully predict the direction of possible travel and may be kicked into the transport guide.

Please refer to the third and figure four, the kick board (15) on the invention Under the invention, the shape of the kick plate (10) is designed to be an asymmetrical kick (25). The upper kick plate (15) has a length smaller than the length of the lower kick plate (16), but the upper kick plate (10) is the same as the lower kick plate (10). In order to maintain the kick plate, the steel surface is in contact with the curved surface. The end length of the steel plate with a stable process and the process length can be about 9 〇cm. The length of the upper kick plate is shortened. The end length of the steel end can be reduced, so as to save waste. The n kick plate (15) above the invention still needs to be kicked to shorten the rear end of the steel (). (i 5) The length shall be less than the length of the steel tail (24) after shortening 201201988 to ensure that the steel tail (24) does not bounce. According to the embodiment of the present invention, when the length of the upper kick plate (10) is about 23 cm, the length of the steel tail portion (24) to be cut can be shortened to about 60 cm. [The kick plate (丨5) of the present invention is still kicked to the tail of the steel. (Before the center of gravity of '2' and 0 does not cause the steel tail (24) to bounce up' so that 3% of the waste can be saved. When considering the need for hot milk steel for different pipe diameters (must 9.5mm~0= When 22.5mm), the length of the kick plate is too short, so that the hot-dry steel of the smaller pipe diameter is too large, so the process stability will also be reduced. So the shorter the kick plate (15) length design It is not possible to obtain a stable process. Although the invention is disclosed in the foregoing preferred embodiments, it is not intended to limit the invention, and any 孰翌μ1 can be used without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is subject to the definition of the patent application.
