An inlet platform for a seamless steel pipe punching machine

Abstract

The present invention relates to the technical field of metal pipe processing, and in particular to an inlet platform of a seamless steel pipe punching machine. The inlet platform of the seamless steel pipe punching machine is provided with two groups of support components, and the lifting mechanism of the support component drives the second end of the discharge seat to move between the material receiving position and the material releasing position. When the lifting mechanism is located at the material receiving position, the billet pusher cylinder pushes the pipe billet on the discharge trough into the rolling device. When the punching machine fails, the lifting mechanism descends to the material releasing position, and the pipe billet on the discharge trough falls, and then the pipe billet can be collected, so that when the main machine or the exit platform of the punching machine fails, the pipe billet stays in the heating furnace for continuous heating, thereby increasing the oxide scale on the surface of the pipe billet and causing the waste of resources. The inlet platform of the seamless steel pipe punching machine automatically collects the pipe billet, avoiding the safety hazard caused by manual collection.

Description

Technical Field

[0001] The invention relates to the technical field of metal pipe processing, in particular to an inlet platform of a seamless steel pipe punching machine. Background Art

[0002] Piercing of tube billets is one of the important processes in the production of seamless steel pipes. This process is to pierce and roll solid tube billets into hollow rough tubes through a piercing machine, and is the first process of metal deformation. Among them, the tube billet piercing process is that the roller device of the piercing machine rotates, the push rod trolley drives the head, and the push rod runs to the working position. After the heated tube billet enters the tube billet seat on the inlet table, the pusher on the inlet table pushes the tube billet into the main seat of the piercing machine, and the roller device of the piercing machine rotates to bite the tube billet into the rolling piercing.

[0003] The structure of the traditional seamless steel pipe piercing machine entrance table includes a base fixed to the ground, a tube base and a lifting mechanism installed on the base to adjust the height of the tube base. When the traditional piercing machine suddenly fails in the main machine, the first stage of the exit table, and the second stage of the exit table, the tubes stored in the heating furnace cannot be processed. If the tubes are continued to be heated, the tubes will be overheated, the oxide scale on the surface will increase, and resources and fuel will be wasted. If the tubes are transported out, they need to be manually clamped out with pliers, which is prone to safety problems. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] like Figure 3-Figure 4 As shown, this embodiment provides an inlet station of a seamless steel pipe punching machine, including a power mechanism 1, a rolling roller device 2, a push cylinder (not shown) and two universal shafts 4. One end of the universal shaft 4 is connected to the power mechanism 1, and the other end of the universal shaft 4 is connected to the rolling roller device 2. The power mechanism 1 drives the universal shaft 4 to rotate, thereby driving the rolling roller device 2 to rotate. One end of the push cylinder is connected to the power mechanism 1, and the other end of the push cylinder is used to push the tube. In actual application, the rolling roller device 2 is set on the main machine base 3, and the power mechanism 1 includes a power source and a reducer connected to the power source. It should be noted that in Figure 3 The connection between the cardan shaft 4 and the roller device 2 is not shown. Figure 4 Only the position of the cardan shaft is shown.

[0032] In this embodiment, the entrance platform of the seamless steel pipe punching machine also includes two groups of support components 5, which are respectively arranged on both sides of the axial direction of the universal shaft 4. The two groups of support components 5 include a support frame 51, a discharge seat 52 and a lifting mechanism 53. The first end of the discharge seat 52 is hinged to the support frame 51, the second end of the discharge seat 52 is hinged to the top of the lifting mechanism 53, and the bottom end of the lifting mechanism 53 is hinged to the support frame 51. The second end of the discharge seat 52 is provided with a discharge groove 521 to receive the pipe blank. The lifting mechanism 53 drives the second end of the discharge seat 52 to move between the material receiving position and the material releasing position, wherein, Figure 4 The material receiving position and material releasing position of the material discharging seat 52 are shown. When the lifting mechanism 53 is located at the material receiving position, the billet pushing cylinder pushes the tube billet on the material discharging trough 521 into the rolling device 2. When the lifting mechanism 53 descends to the material releasing position, the tube billet on the material discharging trough 521 falls. In order to ensure the stability of the two support frames 51, a cross frame 6 is also included. The cross frame 6 is arranged between the support frames 51, and the two ends of the cross frame are respectively connected to the two support frames 51 to form a door structure. In this embodiment, the lifting mechanism 53 is a hydraulic telescopic cylinder, and of course it can be a lifting mechanism in the form of a guide rail slider.

[0033] The present embodiment provides an inlet station of a seamless steel pipe punching machine. By setting two groups of support components 5, the lifting mechanism 53 of the support component 5 drives the second end of the discharge seat 52 to move between the material receiving position and the material releasing position. When the lifting mechanism 53 is located at the material receiving position, the billet pushing cylinder pushes the pipe billet on the discharge trough 521 into the rolling roller device 2. When the punching machine fails, the lifting mechanism 53 descends to the material releasing position, and the pipe billet on the discharge trough 521 falls, so that the pipe billet can be collected, thereby avoiding the waste of resources caused by the continuous heating of the pipe billet in the heating furnace and the increase of surface oxide scale when the main machine or the outlet station of the punching machine fails. The new inlet station automatically collects the pipe billet and avoids the safety hazard caused by manual collection.

[0034] When the material discharging seat 52 is located at the material receiving position, the second end of the material discharging seat 52 is located between the two universal shafts 4, and the first end of the material discharging seat 52 is located on the side of the higher shaft of the two universal shafts 4, so as to avoid the material discharging seat 52 from interfering with the universal shaft 4 during movement. The "higher shaft" refers to the shaft of the two universal shafts 4 that is relatively higher in horizontal position.

[0035] like Figure 4-5 As shown, the material discharging seat 52 includes a bottom plate 522 and a first side wall 523 and a second side wall 524 respectively arranged on both sides of the bottom plate 522. The first side wall 523, the bottom plate 522 and the second side wall 524 form a U-shaped structure. The top surface of the second side wall 524 is lower than the top surface of the first side wall 523. The second side wall 524 of the material discharging seat 52 is located between the two universal shafts 4. The first side wall 523 of the material discharging seat 52 is located on the high axis side of the two universal shafts 4. The material discharging groove 521 is arranged on the top surface of the second side wall 524. This further ensures that the possibility of interference between the material discharging seat 52 and the universal shaft 4 is reduced. Among them, the first side wall 523 of the discharge seat 52 is hinged to the support frame 51, which serves as the rotation center of the discharge seat 52. The bottom end of the second side wall 524 of the discharge seat 52 is hinged to the lifting mechanism 53. When the lifting mechanism 53 descends, the lower end of the lifting mechanism 53 rotates around the hinge point of the support frame 51, thereby driving the second side wall 524 of the discharge trough 521 to rotate around the hinge point of the first side wall 523 and the support frame 51, so that the tube blank placed in the discharge trough 521 falls, and since the top surface of the second side wall 524 is lower than the top surface of the first side wall 523, the reliability of the tube blank falling is guaranteed.

[0036] like Figure 4 As shown, the cross section of the discharge trough 521 is V-shaped, which is convenient for the storage stability of the tube blanks and avoids the rotation of the tube blanks.

[0037] like Figure 6As shown, this embodiment also includes a slip mechanism 7, wherein the slip mechanism is installed in the middle part of the cross frame 6, and the slip mechanism 7 includes a slip 71 and a driving member 72. Specifically, the driving member 72 is a cylinder, and the cylinder is installed in the middle part of the cross frame 6 through a cylinder support. One end of the cylinder is connected to the slip 71 through a connecting member 73. The driving member 72 drives the slip 71 to rotate so that the slip 71 opens and closes on the discharge trough 521. When the slip 71 is buckled with the discharge trough 521, a closed space is formed to prevent the tube blank from swinging. Among them, the slip 71 is an arc-shaped or inverted V-shaped structure.

[0038] In this embodiment, if Figure 4 and Figure 7 As shown, the inlet station of the seamless steel pipe punching machine also includes a receiving seat 8, which is arranged below the unloading seat 52. The receiving seat 8 is provided with an inclined L-shaped receiving groove 81 to facilitate the rolling of the tube blank to the designated position.

[0039] In actual application, in order to reduce the production cost of the material receiving seat 8, the wall thickness of the material receiving seat 8 is set to be narrower. In this embodiment, at least two material receiving seats 8 are included. The material receiving seats 8 are arranged along the axial direction of the universal shaft 4 and are arranged between two support frames 51.

[0040] Working principle of the entrance table of seamless steel pipe piercing machine:

[0041] When the punching machine works normally, that is, the main machine, the first stage of the outlet platform or the second stage of the outlet platform of the punching machine do not fail, at this time, the cylinder rod of the hydraulic telescopic cylinder extends, the discharge seat 52 is in the working position, and the cylinder rod of the slip mechanism 7 extends to open the buckle tile, and the opened buckle tile and the V-shaped discharge groove 521 on the discharge seat 52 form an opening, and the heated tube blank enters the discharge groove 521 through this opening, and then the cylinder rod of the cylinder of the slip mechanism 7 retracts to drive the buckle tile to close, and the closed buckle tile and the V-shaped discharge groove 521 of the discharge groove 521 form a closed space, and the buckle tile can limit the swing of the tail end of the blank during punching. Then the push cylinder works to push the tube blank into the roller device 2 on the main machine seat 3 of the punching machine for punching, and the power mechanism 1 drives the universal shaft 4 to rotate and then drives the roller device 2 to rotate, and the tube blank is bitten in at this time.

[0042] When the punching machine fails, that is, the main machine, the first stage of the outlet platform or the second stage of the outlet platform fails, at this time, the cylinder rod of the hydraulic telescopic cylinder extends, the discharge seat 52 is in the working position, and the cylinder rod of the slip mechanism 7 extends to open the buckle shoe, and the opened buckle shoe and the V-shaped discharge groove 521 on the discharge seat 52 form an opening, and the heated pipe blank enters the discharge groove 521 through this opening. At this time, the cylinder rod of the hydraulic telescopic cylinder retracts, and the lower end of the hydraulic telescopic cylinder rotates around the hinge point of the support frame 51, thereby driving the second side wall 524 of the discharge groove 521 to rotate around the hinge point of the first side wall 523 and the support frame 51, so that the pipe blank placed in the discharge groove 521 rolls down to the L-shaped receiving groove 81 of the receiving seat 8, completing the work of collecting the pipe blanks, and finally the cylinder rod of the hydraulic telescopic cylinder extends, and the discharge seat 52 returns to its position, and the next collection work is carried out.
