[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] like Figures 1 to 6 As shown, a hot-rolled bar pushing device comprises:

[0044] A push rod 1, wherein the push rod 1 is movably connected to a base 8;

[0045] A guide assembly, wherein the guide assembly guides the moving direction of the push rod 1;

[0046] A driving assembly, wherein the output end of the driving assembly is connected to the push rod 1 through an adjusting assembly 4, and the length of the adjusting assembly 4 is adjustable;

[0047] The push plate 2 is detachably connected to an end of the push rod 1 away from the driving assembly.

[0048] The guide assembly includes three guide wheels 3, each guide wheel 3 is rotatably connected to a mounting seat 301, and the mounting seat 301 is fixedly connected to the base 8;

[0049] Two of the guide wheels 3 are used to support the lower end surface of the push rod 1, and the other one limits the upper end surface of the push rod 1. The contact surface between the guide wheel 3 and the push rod 1 is an arc contact, which ensures that the push rod will not shake left and right during the forward and backward movement. The lower guide wheel 3 supports the push rod 1, and the upper guide wheel 3 and the push rod 1 have a gap of 1-2mm to ensure that the push rod 1 is not stuck during the movement.

[0050] The push rod 1 is a cylindrical rod, and an annular groove 302 matching the cylindrical rod is opened on the outer wall of the guide wheel 3. The push rod 1 is located on the inner side of the annular groove 302; there is a gap between the push rod 1 and the guide wheel 3 that limits the upper end surface of the push rod 1.

[0051] The driving assembly includes a hydraulic cylinder 5 and a first swing arm 6. The lower end of the first swing arm 6 is hinged to the base 8, the housing of the hydraulic cylinder 5 is hinged to the base 8, and the output shaft of the hydraulic cylinder 5 is hinged to the second swing arm 9. The upper end of the first swing arm 6 is hinged to one end of the adjustment assembly 4, and the other end of the adjustment assembly 4 is hinged to the push rod. The hydraulic cylinder 5 is assembled with an intermediate trunnion swing hydraulic cylinder 5, which is more flexible when working. The trunnion bearing seat of the hydraulic cylinder 5 and the base 8 are connected with a concave and convex surface, which makes the hydraulic cylinder 5 more stable when working.

[0052] The lower ends of the first swing arm 6 and the second swing arm 9 are fixedly connected to the hinge shaft 7, and the hinge shaft 7 is hinged to the base 8; there are multiple first swing arms 6, and each first swing arm 6 is correspondingly provided with a push rod 1, and the axes of the push rods 1 are arranged in parallel. The adjustment component 4 includes two hinge rings 401 and an adjustment tube 402, one of which is fixed with a left-handed threaded column 404, and the other hinge ring 401 is fixed with a right-handed threaded column 405. The inner side of one end of the adjustment tube 402 is provided with a left-handed thread, and the inner side of the other end is provided with a right-handed thread. The two ends of the adjustment tube 402 are threadedly connected with the left-handed threaded column 404 and the right-handed threaded column 405 respectively; one of the hinge rings 401 is hinged to the upper end of the swing arm, and the other hinge ring 401 is hinged to the end of the push rod 1 away from the push plate 2. The positions of the two hinge rings 401 can be adjusted by rotating the adjusting tube 402, thereby adjusting the position of the push plate 2 in the horizontal direction, so that the two push plates 2 can be aligned, thereby improving the stability of the pushing action.

[0053] The regulating tube 402 is provided with a plug hole 403 , and the axis of the plug hole 403 is perpendicular to the axis of the regulating tube 402 .

[0054] The push plate 2 is a structural member made of wear-resistant steel, and the push plate 2 made of wear-resistant steel prolongs the service life of the device.

[0055] The push rod 1 is fixed with a mounting plate 101 corresponding to the push plate 2, and the push plate 2 is fixed with side plates 202 corresponding to the mounting plate on both sides, and the distance between the two side plates 202 matches the width of the mounting plate 101; the mounting plate 101 is provided with a second through hole 103, and the push plate 2 is provided with a first through hole, and the first through hole is provided with a mounting bolt 10, and the mounting bolt 10 passes through the first through hole and the second through hole 103 and is threadedly connected with a nut. The two side plates 202 play a positioning role for the push plate 2, improving the efficiency of installation and replacement. When the push plate 2 is worn after long-term use, the replacement can be completed by loosening the mounting bolt 10, and the process is convenient.

[0056] The push plate 2 is provided with a V-shaped groove 201, and the second through hole 103 is a strip through hole, and the length direction of the strip through hole is vertically arranged; the upper and lower ends of the mounting plate 101 are fixed with an adjustment plate 102, and the push plate 2 is located directly between the two adjustment plates 102, and two threaded holes 1 are opened on the adjustment plate 102 at the lower end, and a threaded hole 2 is opened on the adjustment plate 102 at the upper end. The threaded hole 1 is internally threadedly connected with a support bolt 11, and the support process supports the lower end surface of the push plate 2, and the adjusting threaded hole 2 is internally threadedly connected with a limiting bolt 12, and the limiting bolt 12 limits the upper end surface of the push plate 2; the threaded hole 2 corresponds to the position between the two threaded holes 1. The setting of the V-shaped groove 201 plays a certain positioning role, which prevents the round bar from shaking when pushing the round bar and improves the stability of the pushing process. Loosening the mounting bolts 10, the supporting bolts 11 and the limiting bolts 12 can adjust the height of the push plate 2 and then adjust the position of the V-shaped groove 201 to be suitable for pushing round bars of different diameters. The setting of the supporting bolts 11 and the limiting bolts 12 reduces the force on the mounting bolts 10 and prevents the mounting bolts 10 from bending during use.

[0057] Working process:

[0058] When this scheme is implemented, when the rod reaches the left side of the push plate 2, the output shaft of the hydraulic cylinder 5 extends, driving the first swing arm 6, the hinge shaft 7, and the second swing arm 9 to rotate. The second swing arm 9 drives the push rod 1 to move through the adjustment component 4. The push plate 2 at the front end of the push rod 1 pushes the rod to move. The guide component plays a guiding role, making the movement process of the push rod 1 more stable. The push plate can be detachably connected to the push plate, which is convenient for replacement and improves maintenance efficiency.
