[0002] Rolling mills are devices that perform the metal rolling process and are widely used in the forming of various metal materials. Rolling mills are classified in various ways based on the number and arrangement of rollers. Conventional rolling mills primarily consist of rollers, a stand, a roll gap adjustment device, a roll temperature control device, a transmission, a lubrication system, a control system, and a roll removal device. Precision rolling mills, on the other hand, incorporate devices to ensure rolling accuracy.

[0003] In the current existing technology, strip material plates are fed into the working rollers of the rolling mill under the feeding action of the conveying device for rolling processing. However, some products require the material plates to be cut at equal intervals before rolling. During the cutting process, the feeding action of the output device on the material plates needs to be stopped. This process will reduce the working efficiency of the rolling mill in rolling the material plates.

[0004] Therefore, in order to solve the above problems, a material plate cutting device for rolling mill production is proposed. Utility Model Content

[0009] Preferably, adjacent side walls of the two lifting sliders are each provided with a pressing roller mounted thereon via a bearing, the axis of the pressing roller coincides with the axis of the supporting roller, and the axis of the pressing roller is located directly above the supporting roller.

[0011] Preferably, one end of the elastic telescopic rod is fixedly connected to a connecting bracket, and the connecting bracket is vertically fixed to the side wall of the lifting slider.

[0012] Preferably, the bottoms of the two supporting side panels are both equipped with roller bases via brackets.

[0013] Preferably, the bottom cut surface of the portal frame base is coplanar with the bottom surface of the portal frame.

[0014] Beneficial effects of the utility model:

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figure 1 - Figure 4 The utility model provides a material plate cutting device for rolling mill production, including a gantry 1, both ends of the side walls of the gantry 1 are vertically fixed with limit guide rods 11, the outer walls of the limit guide rods 11 on both sides are covered with guide rod sleeves 2, the adjacent side walls of the two guide rod sleeves 2 are fixed with support side plates 3, the opposite side walls of the two support side plates 3 are installed with rangefinder bodies 4, the adjacent side walls of the two support side plates 3 are installed with support rollers 5, the shafts of the two support rollers 5 are respectively connected to the two rangefinder bodies 4, a cutter body 6 is installed between the two support side plates 3 near the adjacent side walls of the gantry 1, one end side plate of the gantry 1 is vertically fixed with a cylinder 7, the output end of the cylinder 7 is fixed with a linkage bracket 71, the linkage bracket 71 is vertically fixed to one of the side plates of the guide rod sleeve 2, the gantry The mutual cooperation between the side limit guide rod 11 of the frame 1 and the side guide rod sleeve 2 of the supporting side plate 3 allows the relative distance between the gantry 1 and the supporting side plate 3 to be actively changed under the action of the cylinder 7. The material plate passes over the supporting roller 5 between the supporting side plates 3, and the rangefinder body 4 can control the length of the material plate passing over the supporting roller 5. The cylinder 7 is connected to the guide rod sleeve 2 through the linkage bracket 71. When the length reaches the cutting standard, the thrust of the cylinder 7 on the supporting side plate 3 is released. Under the thrust of the clamped material plate, the supporting side plate 3 moves as a whole to the position of the lower gantry 1. At this time, the cutter body 6 cuts the material plate, and then restores the thrust of the cylinder 7 to make the supporting side plate 3 move away from the gantry 1. During the cutting process, the feeding force of the feeding device on the material plate can be always guaranteed;

[0026] like Figure 3 and Figure 4As shown, the side panels of the two supporting side panels 3 are each provided with a longitudinal straight slot 31, and the interior of the two longitudinal straight slots 31 is clamped with a lifting slider 8, and the adjacent side walls of the two lifting sliders 8 are each installed with a pressing roller 81 through a bearing, and the axis of the pressing roller 81 coincides with the axis of the supporting roller 5, and the axis of the pressing roller 81 is located directly above the supporting roller 5, and the top of the two supporting side panels 3 is installed with an elastic telescopic rod 9 through a bracket, and one end of the elastic telescopic rod 9 is fixedly connected to a connecting bracket 91, and the connecting bracket 91 The lifting slider 8 is vertically fixed to the side wall of the lifting slider 8, and the supporting side plate 3 is used to install the lifting slider 8 through the longitudinal straight slot 31. The lifting slider 8 is linked with the elastic telescopic rod 9 through the connecting bracket 91, which makes the lifting slider 8 as a whole always have an elastic force to press down, so that the pressing roller 81 can cooperate with the supporting roller 5 to clamp the material sheet. This clamping action can make the supporting side plate 3 as a whole move with the feeding action of the material sheet when the supporting force of the cylinder 7 is released, and can adapt to the change of the thickness of the material sheet within a certain range.

[0027] like Figure 1 As shown, the bottom of the two supporting side panels 3 are both mounted with roller bases 10 through brackets. The bottom cross-section of the roller base 10 is coplanar with the bottom surface of the portal frame 1. The roller bases 10 support the supporting side panels 3, reducing the resistance encountered by the supporting side panels 3 as a whole during their movement toward the portal frame 1, thereby increasing the rationality of the device structure.

[0028] Working principle: The mutual cooperation between the side limit guide rod 11 of the gantry 1 and the side guide rod sleeve 2 of the supporting side plate 3 allows the relative distance between the gantry 1 and the supporting side plate 3 to be actively changed under the action of the cylinder 7. The material plate passes over the supporting roller 5 between the supporting side plates 3, and the rangefinder body 4 can control the length of the material plate passing over the supporting roller 5. The cylinder 7 is connected to the guide rod sleeve 2 through the linkage bracket 71. When the length reaches the cutting standard, the thrust of the cylinder 7 on the supporting side plate 3 is released. Under the thrust of the clamped material plate, the supporting side plate 3 moves as a whole to the position of the gantry 1. At this time, the cutter body 6 cuts the material plate, and then restores the thrust of the cylinder 7 to allow the supporting side plate 3 to move to the position of the gantry 1. The plate 3 is away from the gantry 1. The feeding force of the feeding device on the material plate can be always guaranteed during the cutting process. The supporting side plate 3 is installed on the lifting slider 8 through the longitudinal straight slot 31, and the lifting slider 8 is linked with the elastic telescopic rod 9 through the connecting bracket 91, which makes the lifting slider 8 as a whole always have an elastic downward pressure force, and then the downward pressure roller 81 can cooperate with the supporting roller 5 to clamp the material plate. The clamping action can make the supporting side plate 3 as a whole move with the feeding action of the material plate when the cylinder 7 releases the supporting force, and can adapt to the change of the thickness of the material plate within a certain range. The supporting side plate 3 is supported by the roller base 10 to reduce the resistance encountered by the supporting side plate 3 as a whole during the movement toward the gantry 1.
