Description

Technical Field

[0001] The invention relates to stainless steel welded pipe processing equipment, in particular to a blanking device of a stainless steel welded pipe flaw detector. Background Art

[0002] Steel pipes are widely used in various aspects of life. Stainless steel welded pipes are highly sought after for their corrosion resistance and aesthetic appeal. The production process involves transferring stainless steel strips of a specified specification onto a production line via a rotating shaft. On the production line, the strips are gradually rolled into round tubes. The resulting tubes are then welded, cooled, and shaped, then polished and cut into sections. Only after passing flaw detection testing can these welded pipes be released for sale.

[0003] Existing flaw detectors consist of a loading device, a testing device, and a discharge device. The discharge device comprises a fixed frame, a conveyor wheel rotatably mounted on the fixed frame, a lifting assembly mounted on the fixed frame, and a discharge ramp mounted on one side of the fixed frame. After inspection, the welded pipe is transferred to the top of the conveyor wheel. The lifting assembly lifts the pipe above the conveyor wheel, allowing it to roll down the discharge ramp to the ground, completing the discharge operation. The rolling discharge method not only damages the welded pipe surface, affecting product quality, but also generates a significant noise that can seriously affect the physical and mental health of workers. This present invention was conceived to address these issues. Summary of the Invention

[0004] The object of the present invention is to provide a blanking device for a stainless steel welded pipe flaw detector, which can avoid damage to the welded pipe and the huge noise generated during the blanking process, thereby ensuring the production quality of the welded pipe and providing a more comfortable working environment for the staff.

[0005] The above-mentioned technical objectives of the present invention are achieved through the following technical solutions: a blanking device of a stainless steel welded pipe flaw detector, comprising a fixed frame and several conveying wheels arranged in a straight line and mounted on the fixed frame, each of the conveying wheels comprising a left wheel body and a right wheel body, the left wheel body and the right wheel body moving toward or away from each other, the fixed frame being provided with a right synchronous control component for controlling the synchronous movement of the several right wheel bodies and a left synchronous control component for controlling the synchronous movement of the several left wheel bodies, a lifting docking component being provided at both ends along the arrangement direction of the several conveying wheels, one of the lifting docking components being connected to a control component for controlling its movement, each of the lifting docking components comprising a fixed arm, a lifting slide formed on the fixed arm, a docking rod slidably arranged on the lifting slide and used for inserting the end face of the welded pipe, and a lifting drive component for driving the docking rod to lift and lower, the lifting slide comprising a movable lifting section and a disengagement section connected to the lower end of the movable lifting section, the two disengagement sections extending away from each other to guide the docking rod to separate from the welded pipe.

[0006] By adopting the above technical solution, a control assembly controls the movement of the lifting docking member to lower its height, allowing the welded pipe to be properly transferred to the top of the transmission wheel. The welded pipe above the transmission wheel moves toward the other lifting docking member, which restricts the axial movement of the welded pipe under the action of the lifting docking member and allows the docking rod to be inserted into one end of the welded pipe. The control assembly then controls the movement of the other lifting docking member to insert the docking rod on the lifting docking member into the other end of the welded pipe. The right synchronous control member then controls the right wheel body and the left synchronous control member to control the left wheel body to move in opposite directions, forming a gap between them for the welded pipe to pass through. The lifting drive assembly then drives the docking rod to move within the lifting slide to lower the height of the welded pipe. During the descent process, the docking rod moves from the lifting section to the disengagement section, which is used to lower the welded pipe to the ground. When the docking rod enters the disengagement section, the two docking rods move in opposite directions to separate the docking rod and the welded pipe, thereby completing the welded pipe unloading operation. This method avoids damage to the welded pipe surface and noise generation, thereby ensuring the production quality of the welded pipe and providing a more comfortable working environment for the workers.

[0007] It is further configured that: the control component includes a movable seat that reciprocates along the arrangement direction of the transmission wheels, a first driving member and a second driving member that drive the movable seat to move, and the lifting docking component is hinged to the movable seat and driven to rotate by the second driving member.

[0008] By adopting this technical solution, the second drive element controls the lifting and docking member to rotate about the hinge, lowering the height of the lifting and docking member through rotation to prevent it from interfering with the normal transportation of the welded pipe. The first drive element then drives the movable seat along the arrangement direction of the conveyor wheels to change the distance between the two lifting and docking members, adapting to the docking operation of welded pipes of different lengths and enabling the docking rod to be more easily inserted into the welded pipe end face, making this structure more applicable and practical.

[0009] It is further configured as follows: each side of the left wheel body facing the right wheel body is fixedly provided with a load-bearing protrusion, and each side of the right wheel body facing the left wheel body is provided with a load-bearing groove for the load-bearing protrusion to be embedded in, and the load-bearing groove is adapted to the load-bearing protrusion, and the load-bearing protrusion is circular in shape.

[0010] By adopting the above technical solution, the right wheel body drives the load-bearing groove to move toward the left wheel body, and the load-bearing protrusion is inserted into the load-bearing groove to form a load-bearing cooperation between the right wheel body and the left wheel body, so that the weight of the welded pipe can be more evenly distributed to the right wheel body and the left wheel body for bearing, thereby ensuring the bearing strength of the transmission wheel and extending its service life.

[0011] It is further configured as follows: the lifting section includes a moving section and a left section and a right section located below the moving section, the left section and the right section are symmetrically arranged in the vertical direction and the upper ends of the two are connected in parallel with the lower end of the moving section, the lower ends of the left section and the right section are both connected to the disengagement section, and the fixed arm is provided with a selection component for controlling the docking rod to enter the left section or the right section.

[0012] By adopting the above technical solution, after the welded pipe is tested by flaw detection and transferred to the top of the conveyor wheel, qualified products and unqualified products will be generated. According to the difference in the products after the test, the moving path of the docking rod is controlled by selecting components. If the welded pipe is a qualified product, the docking rod can be transferred from the moving section to the left side of the segment. If the welded pipe is an unqualified product, the docking rod can be transferred from the moving section to the right side of the segment. In this way, the qualified and unqualified products can be automatically divided and placed, which is more practical.

[0013] It is further configured that: the selection component includes a guide plate hinged between the upper end of the left segment and the upper end of the right segment, and a third driving member driving the guide plate to rotate.

[0014] By adopting the above technical solution, the third driving member drives the guide plate to rotate, and the guide plate is used to switch the docking rod into the left segment or the right segment, thereby realizing selection control.

[0015] It is further configured to include a guide ball fixedly arranged on the docking rod and slidingly matched with the lifting slide, and the guide ball guides the docking rod to move in the lifting slide.

[0016] By adopting the above technical solution, the guide ball is provided to guide the docking rod to move in the lifting slide, thereby ensuring stable operation of the action.

[0017] It is further configured that: the lifting drive assembly includes a moving block that is reciprocatingly slid along the vertical direction on the fixed arm, a lifting screw that is rotatably set on the fixed arm and threadedly connected to the moving block, and a fourth driving member that drives the lifting screw to rotate, and a control hole is formed on the moving block for the docking rod to pass through, and the control hole extends along the horizontal direction and the length is greater than the distance between the left segment and the right segment.

[0018] By adopting the above technical solution, the fourth driving member drives the lifting screw to rotate, and the rotating lifting screw drives the moving block to perform lifting movement. The moving moving block drives the docking rod to move in the lifting slide under the action of the control hole, and by setting the control hole in a long strip shape, it is ensured that the docking rod can normally enter the left segment or the right segment.

[0019] It is further configured as follows: a bearing platform is provided below the transmission wheel, two guiding arc surfaces are provided on the bearing platform and are symmetrically arranged along the arrangement direction of the transmission wheels, and buffer pads are provided on the two guiding arc surfaces.

[0020] By adopting the above technical solution, the two guiding arc surfaces correspond to the left segment and the right segment respectively. The welded pipe falling from the left segment moves toward one side under the guidance of the corresponding guiding arc surface, and the welded pipe falling from the right segment moves toward the other side under the guidance of the corresponding guiding arc surface, so as to more conveniently realize the partitioned placement, facilitate the subsequent handling of the welded pipe, and be more practical.

[0021] In summary, the present invention has the following beneficial effects: the present invention can avoid damage to the welded pipe and the huge noise generated during the blanking process, thereby ensuring the production quality of the welded pipe and providing a more comfortable working environment for the staff.
