Description

Technical Field

[0001] The utility model relates to the technical field of discharge mechanisms, in particular to an anti-jamming discharge mechanism for seamless steel pipe processing. Background Art

[0002] The table tube rolling mill is a process equipment that uses annular holes to cold-roll rough tubes. The machine has good blanking performance and can also roll non-ferrous metal seamless tubes of ordinary precision. The biggest feature of the tube rolling mill is its high material utilization rate, and its precision and surface roughness are better than those of cold-drawn tubes. Nowadays, most table tube rolling mills on the market require a discharge mechanism when in use to realize the sequential discharge of tubes. After searching, the prior art (application number: CN202021529542.5) records "a table-type tube rolling machine for producing seamless steel pipes, including a tube rolling machine body and a feeding mechanism. The feeding mechanism is installed on one side of the tube rolling machine body. The external personnel can place the seamless steel pipe inside the discharge bin for storage. The seamless steel pipe falls to the upper side of the limit groove and the feeding platform through the discharge trough and the slide plate to wait for feeding processing. The slide plate can allow the seamless steel pipe to slide down while avoiding the situation where it cannot slide down due to the angle being too high or too low. The limit groove is V-shaped and the lower end is narrow to avoid the seamless steel pipe being stuck on the inside and affecting the feeding. When the seamless steel pipe slides on the surface of the limit groove, the pneumatic cylinder on the rear side will drive the telescopic sleeve and the telescopic rod to move. The telescopic rod pushes the seamless steel pipe into the processing bin for processing through the push plate. The buffer block can be pushed inside the limit groove to allow the seamless steel pipe to quickly enter the inner cavity of the processing bin, thereby improving the overall work efficiency."

[0003] However, although the feeding mechanism involved in the table-type tube rolling mill for seamless steel pipes in the prior art has achieved the discharge effect, it still has some shortcomings: the existing seamless steel pipe discharge mechanism lacks the effect of intermittent and sequential discharge, resulting in the pipes still maintaining mutual extrusion contact during the sliding discharge process. Therefore, the impact force of the downward movement may be large, resulting in the pipes being scattered or getting stuck in the discharge groove, and the positioning feeding effect cannot be achieved. Secondly, since the pipes are in contact and slide with each other, it is not convenient to perform surface defect detection on the transported pipes. Utility Model Content

[0004] In order to overcome the defects of the prior art, a discharging mechanism with an anti-stuck state for processing seamless steel pipes is provided to solve the problems that the existing discharging mechanism for seamless steel pipes still has the phenomenon of stuck or scattered discharging, and is inconvenient for surface defect detection of pipes.

[0005] In order to achieve the above-mentioned purpose, a material discharge mechanism for preventing jamming for processing seamless steel pipes is provided, comprising: a pushing mechanism and a feeding mechanism, wherein the pushing mechanism is arranged at the front side of the feeding mechanism, and a pipe rolling mill is arranged on the right side of the pushing mechanism, the feeding mechanism comprises a slot plate, and an inclined plate is connected between the slot plate and a receiving plate included in the pushing mechanism, and a through hole groove is provided at the bottom of the slot cavity in the slot plate, the feeding mechanism also comprises a rocker arm assembly located on the outside of the slot plate, and the rocker arm assembly comprises a U-shaped frame hinged on the outer wall of the slot plate, and an eccentric wheel is slidably connected to the lower side of the U-shaped frame, an electric push rod is installed on the left side of the receiving plate, and a limiting groove is provided on the upper side of the receiving plate.

[0006] Furthermore, a bracket is connected to the lower end of the slot plate, and an N-shaped detection frame is installed on the upper side of the slot plate, and a visual camera is installed on the lower side of the detection frame.

[0007] Furthermore, an upper swing rod is connected to the upper side of the U-shaped opening end of the U-shaped frame, and a lower swing rod is connected to the lower end of the U-shaped opening end, and the upper swing rod and the lower swing rod are respectively located on the upper and lower sides of the slot plate.

[0008] Furthermore, an upper limit rod is connected to the lower side of the end of the upper swing rod, and a lower limit rod is connected to the lower side of the end of the lower swing rod, and both the upper limit rod and the lower limit rod are located in the through hole groove, and the upper limit rod and the lower limit rod are staggered in front and back positions in the top view direction.

[0009] Furthermore, the arc-shaped end of the U-shaped frame is connected to a hinge shaft, and the hinge shaft is rotatably connected to the outer baffle plate of the slot plate.

[0010] Furthermore, a motor is connected to the left side of the eccentric wheel, and the output shaft of the motor is eccentrically connected to the eccentric wheel, while the outer edge of the eccentric wheel is slidably connected to the lower swing rod.

[0011] Furthermore, the limiting groove is configured as a conical groove cavity structure, and a limiting baffle is provided on the front side of the groove opening of the limiting groove, and a slidingly connected push block is provided in the limiting groove, and the push block is connected to the telescopic end of the electric push rod through a connecting rod.

[0012] The beneficial effects of the utility model are:

[0013] 1. The slot plate included in the unloading mechanism is used to lay the seamless steel pipe neatly and flatly inside the slot cavity, and the slot plate is set to an inclined state to facilitate the thrust of sliding in the direction of the pushing mechanism. The swing rod assembly includes a U-shaped frame, an upper swing rod, a lower swing rod, an upper limit rod and a lower limit rod, so that when the steel pipe passes through the through-hole slot, it is blocked and released one by one by the limit rods swinging up and down, thereby achieving the effect of intermittent unloading, so that the steel pipe entering the limit groove on the upper side of the receiving plate is in an independent state, thereby avoiding the phenomenon of being stuck due to mutual squeezing during the sliding process, or the phenomenon of being scattered due to excessive impact force;

[0014] 2. The inspection frame installed on the upper side of the trough plate and the visual camera installed on the lower side of the inspection frame are used to detect appearance defects of the steel pipes rolling in the trough plate. Since the inspection frame is installed on the front side of the through-hole slot, the steel pipes passing through the inspection frame are all independent individuals, so that when shooting, the steel pipes can be prevented from being pushed and connected, which makes it impossible to capture the entire picture of the steel pipes, thereby facilitating defect detection on the surface of the pipe.

[0020] Reference Figures 1 to 4 As shown, the utility model provides an anti-stuck material discharge mechanism for seamless steel pipe processing, comprising: a pushing mechanism 1 and a feeding mechanism 2, the pushing mechanism 1 is arranged at the front side of the feeding mechanism 2, and a tube rolling mill 3 is arranged on the right side of the pushing mechanism 1, the feeding mechanism 2 comprises a slot plate 21, and an inclined plate 22 is connected between the slot plate 21 and the receiving plate 15 included in the pushing mechanism 1, and a through hole slot 23 is opened at the bottom of the slot cavity in the slot plate 21, and the feeding mechanism 2 also includes a swing rod assembly 24 located outside the slot plate 21, The rocker assembly 24 includes a U-shaped frame 241 hinged on the outer wall of the groove plate 21, and the lower side of the U-shaped frame 241 is slidably connected with an eccentric wheel 245, the left side of the receiving plate 15 is installed with an electric push rod 11, and the upper side of the receiving plate 15 is provided with a limiting groove 14, the limiting groove 14 is set as a conical groove cavity structure, and the front side of the groove of the limiting groove 14 is provided with a limiting baffle, and a slidingly connected push block 13 is provided in the limiting groove 14, and the push block 13 is connected to the telescopic end of the electric push rod 11 through the connecting rod 12.

[0021] In this embodiment, the pushing mechanism 1 and the unloading mechanism 2 constitute the main structure of the anti-stuck unloading mechanism for seamless steel pipe processing involved in this application.

[0022] Specifically, a bracket is also provided at the lower end of the pushing mechanism 1, and the height of the bracket is smaller than the height of the unloading mechanism 2, so as to facilitate the self-weight rolling of the steel pipe on the inner side of the groove plate 21, and to facilitate the steel pipe to slide into the limiting groove 14 on the upper side of the receiving plate 15 through the inclined plate 22.

[0023] As a preferred embodiment, by providing a limiting groove 14 with a conical structure and a limiting baffle at the front groove, the steel pipe can accurately fall into the limiting groove 14 when rolling. At this time, a part of the steel pipe is located in the limiting groove 14 and is lower than the upper end surface of the receiving plate 15, thereby achieving a stable supporting effect.

[0024] It should be noted that a photoelectric sensor is installed on the rear side of the limit baffle, so that the electric push rod 11 is started when the steel pipe enters the limit groove 14.

[0025] Specifically, the shape of the push block 13 matches the conical limit groove 14, and the reciprocating extension and retraction time of the electric push rod 11 is matched with the time difference of sequential material discharge, so that when the electric push rod 11 drives the push block 13 to reset, the next steel pipe slides down the receiving plate 15 to prevent the push block 13 from colliding with the steel pipe and causing it to get stuck when it resets.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the lower end of the slot plate 21 is connected to a bracket, and an N-shaped detection frame 25 is installed on the upper side of the slot plate 21, and a visual camera is installed on the lower side of the detection frame 25, the upper side of the U-shaped opening end of the U-shaped frame 241 is connected to an upper swing rod 2411, and the lower end of the U-shaped opening end is connected to a lower swing rod 2412, and the upper swing rod 2411 and the lower swing rod 2412 are respectively located on the upper and lower sides of the slot plate 21, the lower side of the end of the upper swing rod 2411 is connected to the upper limit rod 242, and the lower side of the end of the lower swing rod 2412 is connected to The lower limit rod 243, and the upper limit rod 242 and the lower limit rod 243 are all located in the through hole groove 23, and the upper limit rod 242 and the lower limit rod 243 are staggered in the front and rear positions in the top view direction, the arc end of the U-shaped frame 241 is connected with a hinge shaft 244, and the hinge shaft 244 is rotatably connected to the outer baffle of the slot plate 21, the left side of the eccentric wheel 245 is connected with a motor 246, and the output shaft of the motor 246 is eccentrically connected to the eccentric wheel 245, and the outer edge of the eccentric wheel 245 is slidably connected to the lower swing rod 2412.

[0027] Specifically, the distance between the upper limit rod 242 and the lower limit rod 243 in space is slightly larger than the outer diameter of a single steel pipe, so that when the U-shaped frame 241 (or the rocker arm) is parallel to the slot plate 21, only one steel pipe is located between the upper limit rod 242 and the lower limit rod 243, and the lower limit rod 243 is located in the gap between the front and rear steel pipes in the vertical direction.

[0028] As a preferred implementation, the rotation speed of the motor 246 can be adjusted as needed, thereby adjusting the gap discharge time to adapt to the processing frequency of the tube rolling mill 3.

[0029] When in use, the seamless steel pipes are neatly laid flat on the inner side of the groove cavity of the groove plate 21, and the motor 246 is started. During the driving process of the motor 246 and the eccentric wheel 245, when the lower limit rod 243 moves upward, the upper limit rod 242 moves upward synchronously. At this time, the lower limit rod 243 separates the two steel pipes at the front end, and the steel pipe at the front end is unblocked by the upward upper limit rod 242 to reach a released state. Then, when the eccentric wheel 245 rotates past the current position, the lower limit rod 243 and the upper limit rod 242 move downward synchronously. At this time, the steel pipe on the rear side rolls forward and is blocked by the downward upper limit rod 243, thereby realizing intermittent discharge.

[0030] The utility model discloses a discharge mechanism for preventing jamming or dispersing of materials for processing seamless steel tubes, which can effectively solve the problems that existing discharge mechanisms for seamless steel tubes still have the problems of jamming or dispersing of materials and are inconvenient to detect surface defects of tubes. It realizes the effect of intermittent discharge in sequence on the basis of the existing technology of discharge mechanism for preventing jamming or dispersing of steel tubes, and avoids the problems of jamming or dispersing of steel tubes. It also has the effect of detecting defects on the surface of tubes, and improves the practicability of the equipment.
