[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0023] Embodiment 1

[0024] With reference to Figures 1-6 The full-size sizing machine comprises a roller conveying base 1, further comprises: a plurality of baffle mounting frames 2, which are installed equidistantly on the roller conveying base 1, and each group of two baffle mounting frames 2 are symmetrically arranged above the two sides of the roller on the roller conveying base 1; a first support 3, which is fixedly installed equidistantly on one of the two baffle mounting frames 2 in each group; a gas cylinder 301, which is rotatably connected to the first support 3; a second support 302, which is fixedly installed equidistantly on the upper end of the baffle mounting frame 2 provided with the first support 3; a cross bar 303, which is rotatably connected to the second support 302; a sizing baffle 306, which is equidistantly arranged between each group of two baffle mounting frames 2; a triangular hanger plate 305, which is installed on the upper end of the sizing baffle 306; a hanger rod 304, which is rotatably connected to the triangular hanger plate 305, and the end of the hanger rod 304 away from the triangular hanger plate 305 is rotatably connected between the adjacent cross bar 303.

[0025] Firstly, the roller conveying base 1 starts to operate, and the roller thereon conveys the material to be sized, such as long strip-shaped objects like steel, through rolling. The roller of the roller conveying base 1 continuously rotates, so that the material can move stably forward along the predetermined conveying direction, and prepares for the subsequent sizing operation.

[0026] The plurality of baffle mounting frames 2 are installed equidistantly on the roller conveying base 1, and the two baffle mounting frames 2 in each group are symmetrically arranged above the two sides of the roller, which provides a stable installation basis and positioning frame for the sizing baffle 306. The first support 3 is fixed equidistantly on one of the two baffle mounting frames 2 in each group, which is used as the installation and connection part of the gas cylinder 301, so that the gas cylinder 301 can rotate around it as the fulcrum. Meanwhile, the second support 302 is fixed equidistantly on the upper end of the same baffle mounting frame 2, and the cross bar 303 is rotatably connected to the second support 302, which provides a movable connection structure for the subsequent transmission.

[0027] When the material is transported to the location where the size needs to be determined, the cylinder 301 starts to work, and the telescopic action of the cylinder 301 drives the parts connected with it to move. Since one end of the cylinder 301 is rotationally connected to the first support 3, the telescopic action of the cylinder 301 will push the horizontal rod 303 to rotate around the second support 302, which supports the rotation of the horizontal rod 303. After the rotation of the horizontal rod 303, the movement is transmitted to the sizing baffle 306 through the rotational connection between the suspender 304 and the triangular lifting plate 305. The triangular lifting plate 305 is installed at the upper end of the sizing baffle 306, which connects the suspender 304 and the sizing baffle 306, and enables the sizing baffle 306 to move up and down in the vertical direction between each pair of baffle mounting frames 2.

[0028] Specifically, when the cylinder 301 extends, it pushes the horizontal rod 303 to rotate, and the horizontal rod 303 drives the sizing baffle 306 to descend through the suspender 304. After the sizing baffle 306 descends to the designated position, it will block the material from moving forward, and the front end of the material will contact the sizing baffle 306, thereby determining the length of the material that needs to be cut off at the moment, achieving the purpose of sizing. When the sizing operation is completed, the cylinder 301 retracts, the horizontal rod 303 rotates in the opposite direction, and the sizing baffle 306 is pulled up through the suspender 304, so that the material can continue to be transported forward on the roller conveyor base 1 for the next round of sizing operation or subsequent processing work.

[0029] Through the cooperative work of multiple groups of such equidistantly arranged structures, accurate sizing operation can be performed on materials at different positions during the material conveying process according to actual needs, achieving the function of full-size sizing, and the sizing range can reach 2m-13.5m.

[0030] Embodiment 2:

[0031] Referring to Figures 1-6 The full-size sizing machine is basically the same as Embodiment 1, and further has protrusions arranged on both sides of the sizing baffle 306 close to the triangular lifting plate 305, and the baffle mounting frame 2 is provided with a slot 202 for cooperating with the protrusions. The protrusions are slidingly connected in the slot 202, and through the cooperation of the protrusions and the slot 202, the sizing baffle 306 can be limited to a specific range for lifting.

[0032] A spiral buckle 307 is rotationally connected between the baffle mounting frame 2 close to the second support 302 and the side of the horizontal rod 303 close to the telescopic end of the cylinder 301. Through the arrangement of the spiral buckle 307, when some of the sizing baffles 306 do not need to be hung up, the spiral buckle 307 can be used to limit the horizontal rod 303, so that the sizing baffles 306 can be limited to a specific height, preventing the sizing baffles 306 from descending due to gravity when the cylinder 301 is not working, and effectively ensuring the stability of the sizing baffles 306.

[0033] Embodiment 3:

[0034] Referring to Figures 1-6 The full-size sizing machine is basically the same as that in Embodiment 2, and further comprises: first bearing seats 101 symmetrically fixedly connected to the two sides of the roller conveying base 1 and close to the middle positions of the baffle mounting racks 2; second bearing seats 201 symmetrically arranged at the two sides of the first bearing seats 101 and fixedly connected with the adjacent baffle mounting racks 2; a first screw rod 103 threadedly connected to the first bearing seat 101 away from the air cylinder 301; a second screw rod 104 threadedly connected to the first bearing seat 101 close to the air cylinder 301; the first screw rod 103 and the second screw rod 104 are rotatably connected to the second bearing seats 201 at the two ends, respectively; and a driving mechanism for driving the first screw rod 103 and the second screw rod 104 to synchronously rotate, which is mounted on the baffle mounting rack 2.

[0035] The driving mechanism comprises a speed reducer 102, a chain wheel 105 and a chain 106, the speed reducer 102 is fixedly mounted on the baffle mounting rack 2 provided with the first screw rod 103, and the output end is fixedly connected with one end of the first screw rod 103, the chain wheel 105 is fixedly connected with the ends of the first screw rod 103 and the second screw rod 104 away from the speed reducer 102, and the chain 106 is meshingly connected with the two chain wheels 105.

[0036] In the process of sizing the steel bars, pipes and other steel materials, when the size to be determined is located between two adjacent sizing baffles 306, the speed reducer 102 can be started to drive the first screw rod 103 to rotate, the first screw rod 103 drives the second screw rod 104 to synchronously rotate through the chain wheel 105 and the chain 106, and then the first screw rod 103 and the second screw rod 103 drive the two baffle mounting racks 2 to be adjusted to adjust the positions, so that the positions of the sizing baffles 306 between the two baffle mounting racks 2 can be adjusted, the steel materials can be sized to the specified size, the application range of the sizing machine is further improved, and the sizing range of the sizing machine is from 2m to 13.5m, and the adjustment range covers 1750-13750mm.

[0037] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments, it is not intended to limit the present application.
