DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0018] Example. A large steel pipe cold drawing equipment capable of automatic unloading is composed of Figure 1-3 As shown, it includes a mold base 1, and a feeding support platform 2 and a discharging support platform 3 for automatic unloading are respectively provided on both sides of the mold base 1, and a drawing trolley 4 is provided on the side of the discharging support platform 3; the drawing trolley 4 includes a car body 5, and a hydraulic press 6 for driving the car body 5 to move is provided on one side of the car body 5, and a clamping seat 7 for clamping the steel pipe is provided on the car body 5; the discharging support platform 3 includes multiple groups of first guide plates 27, and a liftable support seat 26 is provided on one side of the first guide plate 27. When the discharging support platform 3 guides the steel pipe, the upper end surface height of the support seat 26 is higher than the height of the upper end surface of the first guide plate 27. When the discharging support platform 3 unloads the steel pipe, the support seat 26 drops to a height of the upper end surface lower than the height of the upper end surface of the first guide plate 27.

[0019] The clamping seat 7 includes a baffle 8 that is perpendicular to the vehicle body 5 and parallel to each other, a second guide plate 9 is provided on the inner side of the baffle 8, a clamping block groove 10 is provided in the second guide plate 9, a vertically arranged rotating shaft 11 is provided in the clamping block groove 10, a clamping block 12 for clamping the steel pipe is provided on the rotating shaft 11, and the clamping block 12 is provided with clamping teeth 14 facing the steel pipe side, a first wedge block 15 driven by a pushing mechanism is provided on one side of the second guide plate 9, a second wedge block 13 corresponding to the first wedge block 15 is provided on the baffle 8, a connecting rod 19 for driving the clamping block 12 to rotate around the rotating shaft 11 is provided on the first wedge block 15, a limit block 20 is provided at the end of the connecting rod 19, and a limit groove 21 corresponding to the limit block 20 is provided on the clamping block 12.

[0020] The opposing surfaces of the first wedge block 15 and the clamping block 12 are parallel to the length direction of the clamping block 12 , a guide block 17 is provided on the opposing surfaces of the first wedge block 15 and the clamping block 12 , and a transverse guide groove 22 is provided near the end of the pushing mechanism of the first wedge block 15 .

[0021] The second wedge block 13 is provided with a guide groove 18 corresponding to the guide block 17 .

[0022] The pushing mechanism includes a hydraulic push rod 23 in the same direction as the length of the baffle 8. A jacket 24 corresponding to the first wedge 15 is provided at the end of the hydraulic push rod 23. A limiting column 25 corresponding to the transverse guide groove 22 is provided in the jacket 24.

[0023] The upper end of the first guide plate 27 is provided with a downwardly inclined guide surface.

[0024] The principle of the present invention is as follows: the steel pipe of the present application is placed on the feed support table 2, and the steel pipe is pushed so that one end of the steel pipe passes through the die base 1. At this time, the drawing trolley 4 moves to the end of the steel pipe. At this time, the height of the upper end surface of the support base 26 is higher than the height of the upper end surface of the first guide plate 27. The hydraulic push rod 23 drives the clamping sleeve 24 to move, so that the clamping sleeve 24 pushes the first wedge block 15 to cooperate with the second wedge block 13. The first wedge block 15 will move along the end surface of the second wedge block 13 to achieve the tightening of the clamping block 12, so that the clamping block 12 can clamp the steel pipe with a good clamping effect. Then, under the action of the hydraulic press 6, the drawing trolley 4 moves away from the die base 1, pulling the steel pipe through the die base 1, and realizing the cold drawing of the steel pipe. Since the clamping block 12 clamps the steel pipe through the clamping teeth 14, a certain indentation will be generated on the surface of the steel pipe during the clamping process, so that when the hydraulic push rod 23 contracts, the clamping block 12 still cooperates with the steel pipe. At this time, since the steel pipe has completely passed through the die base 1, the steel pipe will not generate a large force on the clamping block 12, so that the steel pipe cannot be separated from the clamping block in time, and rapid unloading cannot be achieved. In the process of the first wedge block 15 of the present application moving away from the second wedge block 13, the connecting rod 19 will drive the clamping block 12 to rotate around the rotating shaft 11, so that the clamping block 12 can release the steel pipe, and at the same time the height of the support seat 26 will be lowered. The support seat 26 can be lifted and lowered by arranging hydraulic equipment at the bottom. Since lifting and lowering by hydraulic equipment is a conventional technical means in this field, it will not be explained in detail here. When the upper end face of the support seat 26 moves down to below the upper end face of the first guide plate 27, the steel pipe can move downward along the first guide plate 27 under the action of gravity to achieve automatic unloading.
