[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0054] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0055] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left" and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limitations of the present invention.

[0056] Preferably, in the embodiment of the present invention, the rotation direction of X in the figure is positioned in the first direction.

[0057] Example 1:

[0058] See also Figure 1 The present invention provides a sizing machine for stopping and aligning the ends of rolled materials, comprising:

[0059] Power seat 100;

[0060] The power assembly 200 is rotatably mounted on the power base 100, and the power assembly 200 is tilted;

[0061] The connecting rod seat 300 is provided on one side of the power seat 100;

[0062] The connecting rod assembly 400 is spaced apart and disposed on one side of the power base 100. The connecting rod assembly 400 includes:

[0063] The swing rod 410 is rotatably connected to the side of the power assembly 200 facing away from the power base 100, and the swing rod 410 and the power assembly 200 are arranged at an angle;

[0064] The transmission shaft 420 is rotatably mounted on the connecting rod seat 300 and connected to the rocker arm 410;

[0065] The rocker arm 430 is connected to the transmission shaft 420, and the rocker arm 430 and the rocker rod 410 are arranged at an angle;

[0066] It can be understood that the power component 200 installed obliquely on the power seat 100 is connected to the rocker arm 410. When the power component 200 drives the rocker arm 410 to rotate along the first direction, the transmission shaft 420 connected to the connecting rod seat 300 will rotate accordingly, driving the rocker arm 430 connected to the transmission shaft 420 to rotate.

[0067] A push rod assembly 500 is rotatably mounted on the rocker arm 430;

[0068] The lifting baffle 600 and the side of the top rod assembly 500 facing away from the rocker arm 430 are rotatably connected to the lifting baffle 600, so that when the power assembly 200 drives the rocker arm 410 to rotate along the first direction, it drives the transmission shaft 420 and the rocker arm 430 to rotate along the first direction in turn, and by lifting the top rod assembly 500, the lifting baffle 600 is raised to achieve the stop level.

[0069] It should be noted that the lifting baffle 600 moves up and down within the space formed by the supporting column 810. The supporting column 810 is a key load-bearing component in the sizing machine's operating mechanism. Its primary function is to withstand the high-energy impact loads of the double-length rolled stock and the additional reaction internal stresses generated by the system's movement, while transmitting all of this load to the underground concrete foundation. The main structure utilizes a welded steel rectangular frame, primarily constructed from four steel billets supplemented by several 250H-section steel and channel steel welds, with two mirror-symmetrical lifting runners reserved in the middle.

[0070] Specifically, external force acts on the power assembly 200 connected to the power seat 100, so that when the power assembly 200 drives the rocker arm 410 to rotate along the first direction, the transmission shaft 420 and the rocker arm 430 are driven to rotate along the first direction in turn, and the top rod assembly 500 set on the rocker arm 430 is lifted, so that the lifting baffle 600 moves up and down in the space formed by the supporting column 810, thereby stopping the end of the rolled material. In other words, the low-sub connecting rod mechanism design has the advantages of high structural strength, low contact stress and good wear resistance, which avoids the imbalance of the center of gravity of the lifting baffle 600. In particular, the eccentric layout design of the connecting rod assembly 400 and the installation position design of the power assembly 200 are designed to be on the outside of the lifting baffle 600, which increases the maintenance space, thereby improving the working efficiency of the length-fixing machine.

[0071] Preferably, the power assembly 200 includes a cylinder body 210 and a driving member 220, the driving member 220 is telescopically arranged on the cylinder body 210, the cylinder body 210 is rotatably arranged on the power base 100, the driving member 220 and the rocker arm 410 are rotatably connected, the power assembly 200, the rocker arm 410 and the rocker arm 430 are arranged in sequence in a direction close to the lifting baffle 600, so that when the driving member 220 is retracted relative to the cylinder body 210, the lifting baffle 600 rises.

[0072] In this embodiment, the power assembly 200 is a piston cylinder such as a pneumatic cylinder, and the driving member 220 is a piston rod. The piston rod performs telescopic motion relative to the cylinder body 210. The piston cylinder is connected to a solenoid valve, which controls the movement of the piston rod of the piston cylinder.

[0073] In addition, the supporting column 810 is provided with an upper stop 811 and a lower stop 812. The bottom of the supporting column 810 exposed to the base ground is designed with two groups of lower stops 812 arranged in a mirror-symmetrical manner to reduce the gravitational impact on the system when the lifting baffle 600 falls back to the lowest point; the top of the supporting column 810 is also correspondingly designed with two groups of upper stops 811 to limit the maximum stroke of the highest point of the lifting baffle 600, to prevent the connecting seat 432, the top rod assembly 500 and the hinge seat of the lifting baffle 600 in the connecting rod lifting mechanism from reaching the dead point position of the "three points and one line" of the planar connecting rod mechanism during movement, thereby causing a blocking and jamming accident of the connecting rod mechanism. A displacement sensor 813 can also be provided on the top of the supporting column 810, which can automatically sense and capture the magnetic field signal of the head of the rolled material moving on the conveyor roller within a certain range. When the head of the rolled material moves to a certain position away from the lifting baffle 600, the sensor will send an induction signal to extend the cylinder piston rod in the power mechanism, causing the lifting baffle 600 to rise to the maximum high position in advance, blocking the transmission channel of the conveyor roller, limiting the forward freedom of the rolled material on the conveyor roller, and instantaneously absorbing the initial impact kinetic energy of the rolled material, so that its end faces are stopped flush, waiting for the next shearing process.

[0074] Combined with attachment Figure 1 In the first embodiment, the driving member 220 and the rocker arm 410 are rotationally connected. The connecting rod base 300, which is rotationally connected to the rocker arm 410, is fixed to the ground and cannot move. One side of the rocker arm 430 is connected to the transmission shaft 420, and the rocker arm 430 and the rocker arm 410 are arranged at an angle. The push rod assembly 500 is configured as a straight rod, wherein the push rod assembly 500 is fixedly connected to the rocker arm 430 to further control the movement of the lifting baffle 600 connected to the push rod assembly 500. The power assembly 200 sequentially drives the rocker arm 410, the transmission shaft 420, the rocker arm 430, and the push rod assembly 500, causing the lifting baffle 600 to move up and down within a fixed stroke.

[0075] Example 2:

[0076] Please refer to the attached Figures 2 to 4 The same as the first embodiment is that the sizing machine is used to stop and align the ends of the rolled material, and the sizing machine includes:

[0077] Power seat 100;

[0078] The power assembly 200 is rotatably mounted on the power base 100, and the power assembly 200 is tilted;

[0079] The connecting rod seat 300 is provided on one side of the power seat 100;

[0080] The connecting rod assembly 400 is spaced apart and disposed on one side of the power base 100. The connecting rod assembly 400 includes:

[0081] The swing rod 410 is rotatably connected to the side of the power assembly 200 facing away from the power base 100, and the swing rod 410 and the power assembly 200 are arranged at an angle;

[0082] The transmission shaft 420 is rotatably mounted on the connecting rod seat 300 and connected to the rocker arm 410;

[0083] The rocker arm 430 is connected to the transmission shaft 420, and the rocker arm 430 and the rocker rod 410 are arranged at an angle;

[0084] A push rod assembly 500 is rotatably mounted on the rocker arm 430;

[0085] The lifting baffle 600 and the side of the top rod assembly 500 facing away from the rocker arm 430 are rotatably connected to the lifting baffle 600, so that when the power assembly 200 drives the rocker arm 410 to rotate along the first direction, it drives the transmission shaft 420 and the rocker arm 430 to rotate along the first direction in turn, and by lifting the top rod assembly 500, the lifting baffle 600 is raised to achieve the stop level.

[0086] The power assembly 200 includes a cylinder body 210 and a driving member 220. The driving member 220 is telescopically arranged on the cylinder body 210. The cylinder body 210 is rotatably arranged on the power base 100. The driving member 220 and the rocker arm 410 are rotatably connected. The power assembly 200, the rocker arm 410 and the rocker arm 430 are arranged in sequence in a direction close to the lifting baffle 600, so that when the driving member 220 is retracted relative to the cylinder body 210, the lifting baffle 600 rises.

[0087] The difference between the second embodiment and the first embodiment is that the connecting rod seat 300 includes:

[0088] The stationary base 310 can be fixed on the ground;

[0089] The movable base 320 is movably disposed on the static base 310 . The transmission shaft 420 is disposed on the movable base 320 . The movable base 320 can move in a direction close to or away from the power base 100 .

[0090] In the second embodiment, the connecting rod seat 300 includes a static base 310 fixed to the ground and a dynamic base 320 provided on the static base 310. The dynamic base 320 is movable compared to the static base 310. The transmission shaft 420 is provided on the dynamic base 320. The dynamic base 320 can move in a direction close to or away from the power base 100. It can be seen that more usage requirements can be met by adjusting the position of the dynamic base 320.

[0091] In the second embodiment, please refer to the attached Figure 5 and attached Figure 6The rocker arm 410 includes a slider 411, a lead screw 412 and a locking member 413. The slider 411 can be adjusted in position along the axial direction of the lead screw 412 and fixed in position by the locking member 413. The slider 411 and the power assembly 200 are rotatably connected.

[0092] It is understood that the slider 411 is connected to the lead screw 412 and the end of the power assembly 200, respectively, so that the movement of the power assembly 200 drives the swing arm 410 to rotate. The locking member 413 fixes the position of the slider 411 on the lead screw 412, and the lead screw 412 can be rotated to adjust the position of the slider 411 on the lead screw 412 according to actual conditions. Specifically, the power assembly 200 applies a thrust to the slider 411 connected thereto. The swing arm 410 is provided with a lead screw 412. The internal thread of the slider 411 cooperates with the lead screw 412. When the lead screw 412 is rotated, the slider 411 moves. When the slider 411 is subjected to a thrust, the force can be transmitted through the lead screw 412.

[0093] That is to say, the rocker arm 410 provided by the present invention can not only transmit the power output by the power assembly 200, but also adjust the specific position of the slider 411 through the screw 412, so that the rocker arm 410 is subjected to more reasonable force, reduce contact stress, prevent the rocker arm 410 from being damaged due to uneven force, and increase the service life of the rocker arm 410.

[0094] The above arrangement can solve the problem that the connection position between the power assembly 200 and the rocker arm 410 cannot be adjusted while the rocker arm 410 transmits power.

[0095] It can be understood that the slider 411 can move with the rotation of the screw 412. When the screw 412 stops rotating, the slider 411 will stay at a certain position and no longer move. However, when the slider 411 is subjected to power transmitted from the power component, if the transmitted power is relatively large, it is easy for the slider 411 to be forced to move under the large power, thereby forcing the screw 412 to rotate; this situation will cause the slider 411 to move to a non-ideal force-bearing position, thereby losing the effect that the slider 411 and the screw 412 should achieve.

[0096] Therefore, it is necessary to provide locking members 413 on both sides of the movable direction of the slider 411. The locking members 413 are connected to the screw 412 through threads, and when the locking members 413 press against the slider 411, the relative positions of the slider 411 and the screw 412 will be fixed; in this way, when the slider 411 is adjusted to a suitable position to start transmitting power, the slider 411 can stably transmit power to the screw 412 and the two side panels.

[0097] In the second embodiment, please refer to the attached Figure 7The rocker arm 430 includes a body 431 and a connecting seat 432. One side of the body 431 is fixedly connected to the transmission shaft 420. The connecting seat 432 can move along the length direction of the body 431. The connecting seat 432 and the push rod assembly 500 are rotatably connected.

[0098] It can be understood that the connecting seat 432 is used to be rotatably connected to the top rod assembly 500, and a locking structure is provided on the main body 431 of the rocker arm 430. The locking structure is used to fix the position of the connecting seat 432 on the main body 431. The locking structure can adjust the position of the connecting seat 432 by rotating bolts, etc., thereby affecting the movement distance of the lifting baffle 600.

[0099] Specifically, one end of the body 431 of the rocker arm 430 is connected to the transmission shaft 420. When the length-fixing machine is working, the main function of the body 431 is to transmit the load transmitted by the transmission shaft 420, and the connecting seat 432 with an adjustable relative position of the body 431 is rotatably connected to one end of the push rod assembly 500, and transmits the driving torque to the push rod assembly 500, thereby driving the lifting baffle 600 to perform periodic lifting and lowering movements in the slideway supported by the column 810, and colliding one end of the rolled material in the roller table to cooperate with the cold shearing machine to perform length-fixing shearing operations; further, with the use of the length-fixing machine, the rocker arm 430 may produce a certain usage error, so that the lifting baffle 600 cannot reach the required height, and thus cannot collide one end of the rolled material in the roller table, thereby affecting the length-fixing shearing operation of the cold shearing machine. At this time, the position of the connecting seat 432 on the body 431 can be adjusted according to the size of the error. That is, after the connecting seat 432 is slid to a determined position, the position of the connecting seat 432 and the body 431 is fixed by the locking structure.

[0100] Preferably, a shaft sleeve 414 is provided at the bottom of the rocker arm 410, and the transmission shaft 420 is sleeved in the shaft sleeve 414; a plurality of evenly distributed rectangular key slots are provided around the transmission shaft 420, and the rocker arm 430 is provided with a connecting hole 433 that is compatible with the rectangular key slots. The rectangular key slots and the connecting hole 433 can be plugged in and fixed to adjust the angle between the transmission shaft 420 and the rocker arm 430.

[0101] It can be understood that the sleeve 414 is used to fix the connection between the rocker arm 410 and the transmission shaft 420. In addition, the transmission shaft 420 is provided with a plurality of evenly distributed rectangular key grooves on its circumference, which can cooperate with the connection holes 433 provided on the rocker arm 430, so that when the rocker arm 410 rotates, it drives the transmission shaft 420 to rotate, and then drives the rocker arm 410 connected to the transmission shaft 420 through the key grooves and the connection holes 433 to rotate.

[0102] It should be noted that the rectangular keyway fixed on the transmission shaft 420 and the connecting hole 433 fixed on the rocker arm 430 can adjust the corresponding relationship between the rectangular keyway and the connecting hole 433 according to actual needs, thereby adjusting the angle between the transmission shaft 420 and the rocker arm 430.

[0103] In addition, the rocker rod 410 and the rocker arm 430 can be respectively arranged at different axial positions of the transmission shaft 420 , and the counterweight assembly 700 can be installed at any axial position of the transmission shaft 420 .

[0104] In the second embodiment, please refer to the attached Figure 2 To the attached Figure 4 , the ejector assembly 500 includes:

[0105] A first push rod 510, used to connect to the rocker arm 430;

[0106] The second push rod 530 is used to connect the lifting baffle 600;

[0107] The adjusting member 520 connects the first push rod 510 and the second push rod 530 . By rotating the adjusting member 520 , the first push rod 510 and the second push rod 530 can move away from or closer to each other.

[0108] Specifically, the push rod assembly 500 includes a first push rod 510, a second push rod 530 and an adjusting member 520. The adjusting member 520 is used to adjust the distance between the first push rod 510 connected to the rocker arm 430 and the second push rod 530 connected to the lifting baffle 600, so that the length of the push rod assembly 500 can be lengthened or shortened according to actual needs.

[0109] Preferably, it also includes a sliding seat 900, which is rotatably connected to the top rod assembly 500, and movably connected to the lifting baffle 600. The sliding seat 900 is provided with an internal threaded hole, and the thread in the internal threaded hole is matched with an adjusting screw 910.
