Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, specifically relating to a movable receiving trough that works in conjunction with a piercing machine. Background Technology

[0002] Piercing is the first step in the production of seamless steel pipes. Its function is to pierce solid billets into rough tubes. The piercing machine inlet table is an important auxiliary machine in steel pipe production.

[0003] like Fig. 1-2 The receiving trough 10 is a temporary storage component for the steel billet 90 entering the piercing machine. The steel billet 90 is pushed into the piercing machine (to the left) by the push rod 92. It includes a trough body 10, and a wear-resistant liner 11 is fixed inside the trough body 10.

[0004] As the machine continues to operate, the wear-resistant liners will wear out and need to be replaced, or they may need to be replaced due to changes in the billet type 90.

[0005] The challenge lies in the fact that, in order to better match the inlet of the drilling machine, when replacing the wear-resistant liner, it is necessary to ensure that the lowest point of the bottom surface of the wear-resistant liner 11 is located on the standard plane 91, which is the "optimal height for matching the inlet of the drilling machine". This requires a relatively long replacement time. Utility Model Content

[0006] The technical problem this utility model aims to solve is: how to design a movable receiving trough that works with a perforating machine, and how to shorten the time required to replace the wear-resistant liner.

[0007] The specific technical solution of this utility model is as follows:

[0008] A movable receiving trough for use with a perforating machine includes a trough body and a frame. The frame body includes a fixed frame and a movable frame located on both sides of the bottom of the trough body. The lower part of the movable frame is provided with a plurality of horizontal hinge holes. The upper part of the movable frame extends outward to form an extension platform, and the extension platform is hinged to the piston end of a hydraulic cylinder.

[0009] The installation is set up on the opposite side of the material receiving direction.

[0010] Multiple extension stages and hydraulic cylinders are provided.

[0011] The movable frame has vertical pin holes.

[0012] Abrasion-resistant liners are fixed inside the tank.

[0013] Compared with the prior art, the technical advantage of this utility model is that, since this utility model is mobile, it can be replaced in the background, and the time for replacing the wear-resistant liner is shorter. Attached Figure Description

[0020] The present application will be described in detail below with reference to the accompanying drawings and its specific embodiments.

[0021] As Fig. 3-6 , a mobile receiving chute matched with a piercing machine, comprising a chute body 10 and a frame body.

[0022] As Fig. 3 , the frame body comprises a fixed frame 20 and a movable frame 30 located at the two sides of the bottom of the chute body 10 respectively, the lower part of the movable frame 30 is provided with a plurality of horizontal hinge holes 31, the upper part of the movable frame 30 extends outward to form an extended table 33, and the extended table 33 is hinged to the piston end 40 of an oil cylinder.

[0023] In order to resist the force in the direction of incoming material, the movable frame 30 is arranged at the opposite side of the direction of incoming material. Fig. 3 In the embodiment, the billet 90 enters the wear-resistant lining plate 11 from the right.

[0024] In order to be firm, the extended table 33 and the oil cylinder are provided with a plurality of.

[0025] In order to be firm, the movable frame 30 is provided with vertical pin holes 32.

[0026] The wear-resistant lining plate 11 is fixed in the chute body 10.

[0027] Because the billet is a high-temperature piece, when the billet enters the wear-resistant lining plate 11 and when the push rod 92 pushes the billet 90 (to the left) into the piercing machine, the outer surface of the billet is easy to be oxidized and form an iron oxide skin to fall off, and the iron oxide skin falls in the wear-resistant lining plate 11, which affects the billet 90 to be pushed into the piercing machine.

[0028] Therefore, as Fig. 4-5 , a plurality of water channels 112 are arranged on the wear-resistant lining plate 11, a plurality of water pipe branch lines 51 are arranged in the chute body 10, the water channels 112 and the water pipe branch lines 51 are communicated, the plurality of water pipe branch lines 51 are gathered into a water pipe main line 52, and the outlet of the water pipe main line 52 extends to the outside of the chute body 10.

[0029] The upper part of the groove body 10 is provided with a water spraying pipe 50, and the water spraying direction of the water spraying pipe 50 is consistent with the axial direction of the groove body 10.

[0030] In order to facilitate the formation of the water channel 112, the wear-resistant lining plate 11 comprises a plurality of lining plate units 111, and the gap between two adjacent lining plate units 111 is the water channel 112.

[0031] The working principle is as follows:

[0032] When installing, as Fig. 3-6 , the following steps are included:

[0033] S11, preparation: fixing the fixed frame 20 on the ground, hinging the movable frame 30 on the ground through the hinge hole 31 and the pin shaft, hinging the cylinder body end 41 of the oil cylinder on the ground, and providing a blind hole on the ground at the corresponding position of the pin hole 32.

[0034] S12, opening: the piston rod of the oil cylinder is retracted, the movable frame 30 is turned outwards along the axis of the pin shaft, and the opening of the movable frame 30 and the fixed frame 20 is enlarged.

[0035] S13, hoisting: hoisting the groove body 10 between the movable frame 30 and the fixed frame 20, slowly lowering the groove body 10, and finally removing the hoisting device.

[0036] S14, pressing: the piston rod of the oil cylinder is extended, the movable frame 30 is turned inwards along the axis of the pin shaft, the movable frame 30 and the fixed frame 20 tightly hold the groove body 10, and at this time, the lowest part of the bottom surface of the wear-resistant lining plate 11 is located on the standard plane 91.

[0037] S15, inserting the pin into the pin hole 32 and the blind hole in the ground.

[0038] S16, end.

[0039] When using, as Fig. 3-6 , the following steps are included:

[0040] S21, the billet enters the wear-resistant lining plate 11.

[0041] In this step, the kinetic energy brought by the billet 90 and the kinetic energy finally impacted on the side of the movable frame 30, and the movable frame 30 is supported by a plurality of oil cylinders and pins, which is relatively stable and can withstand the impact of the billet 90.

[0042] S22, the push rod 92 pushes the billet 90 (leftwards) into the piercing machine. Fig. 4

[0043] ​S23. During the return stroke of push rod 92, water spray pipe 50 sprays water. The water sprayed from water spray pipe 50 carries iron oxide scale into water channel 112, water pipe branch line 51, water pipe main line 52 in sequence, and finally flows into the outlet of water pipe main line 52.

[0044] This step not only removes the iron oxide belt, but also cools down the wear-resistant liner 11 and push rod 92, which can extend their service life.

[0045] S24, End.

[0046] When replacing the wear-resistant liner 11, if Fig. 3-6 It includes the following steps:

[0047] S31. Open: Pull out the pin, the piston rod of the oil cylinder retracts, causing the movable frame 30 to flip outward along the axis of the pin, thus increasing the opening between the movable frame 30 and the fixed frame 20.

[0048] S32, Lifting out: The old tank body 10 is lifted away using a lifting device.

[0049] S33. Hoisting: Hoist the new tank 10 between the movable frame 30 and the fixed frame 20, slowly lower the tank 10, and finally remove the hoisting device.

[0050] S34, Pressing: The piston rod of the oil cylinder extends, causing the movable frame 30 to rotate inward along the axis of the pin, so that the movable frame 30 and the fixed frame 20 hold the groove 10 tightly. At this time, the lowest point of the bottom surface of the wear-resistant liner 11 is located on the standard plane 91.

[0051] S35. Insert the pin into the pin hole 32, the blind hole in the ground.

[0052] S36, End.

[0053] For other details, please refer to the existing technology.
