Description

Technical Field

[0001] The utility model relates to a detection machine, in particular to a pipe flaring detection machine. Background Art

[0002] For the production of stainless steel pipes, the performance of the pipes themselves is an important indicator. Their hardness, ductility, etc. will affect the production and use of the pipes. For example, when some pipes are processed, flaring is required at their ends. If the pipes crack during flaring, it means that the hardness and ductility of the pipes are poor. Therefore, it is necessary to detect the flaring of the pipes. Currently, the method for detecting the flaring of pipes is as follows: A conical mold is placed on a workbench, and there is a hydraulic press above the workbench. The pipe is sleeved on the upper end of the mold. During detection, the hydraulic press presses down on the pipe. The pipe is pressed down, and the lower end of the pipe continuously contacts the conical mold to flare the lower end of the pipe. However, the following problems will occur during use: Since the pipe is in close contact with the mold when being pressed down, the pipe is firmly sleeved on the upper end of the mold. When it is necessary to remove the pipe, the staff has to pull it up with force, and sometimes even has to use tools to knock on the pipe first, which is time-consuming and laborious and needs to be further improved. Content of the Utility Model

[0003] In view of the defects of the above-mentioned prior art, the purpose of the utility model is to provide a pipe flaring detection machine.

[0004] The technical solution of the utility model is: A pipe flaring detection machine, including a frame. The middle part of the frame has a working chamber. A workbench is fixed at the bottom of the working chamber. A vertically extending oil cylinder is fixed at the top of the frame. A fixed block is fixed at the end of the piston rod at the lower end of the oil cylinder. A pressing plate is fixedly connected to the bottom of the fixed block. The pressing plate is accommodated in the working chamber. A mold is fixed at the middle position of the top of the workbench. The pipe is placed on the upper end of the mold. The pressing plate is located above the pipe. Two pipe pulling devices for clamping the pipe and driving the pipe to move upward are installed on the workbench. The two pipe pulling devices are respectively located on the left and right sides of the pipe.

[0005] Further, vertical columns extending vertically are fixed at both the left and right ends of the top of the workbench. Sliding sleeves are fixed at both the left and right ends of the pressing plate. The vertical columns pass through the sliding sleeves, and the sliding sleeves are in sliding fit with the vertical columns up and down.

[0006] Further, brackets are fixed at both the left and right ends of the top of the workbench. The pipe pulling devices are fixedly connected to the brackets.

[0007] Further, the pipe pulling device includes a first sliding table cylinder fixed horizontally at the top of the bracket. A first connecting plate is fixed at the end of the first sliding table at the upper end of the first sliding table cylinder. A second sliding table cylinder extending vertically is fixed on the outside of the first connecting plate. A second connecting plate is fixed at the top of the second sliding table on the outside of the second sliding table cylinder. A pneumatic claw is fixed at the top of the second connecting plate.

[0008] Further, the two grippers are respectively located on the left and right sides of the pipe. The first slide cylinder is used to control the left and right movement of the gripper, the second slide cylinder is used to control the up and down movement of the gripper, and the gripper is used to clamp the pipe.

[0009] When applying the pipe flaring detector provided by the present utility model, the beneficial effect is that when it is necessary to remove the detected pipe, the gripper of the pipe pulling device will clamp the pipe and pull the pipe upward, eliminating the need for manual upward pulling of the pipe, saving time and effort, and improving work efficiency.

Detailed Embodiment

[0013] For a more intuitive and complete understanding of the technical solution of the present utility model, the non - restrictive feature description is as follows in combination with the drawings of the present utility model:

[0014] As Figure 1 , Figure 2 shown, the pipe flaring detector includes a frame 1. The middle of the frame 1 has a working bin 2. The bottom of the working bin 2 is fixed with a workbench 3. The top of the frame 1 is fixed with an oil cylinder 4 extending vertically. The end of the piston rod at the lower end of the oil cylinder 4 is fixed with a fixed block 5. The bottom of the fixed block 5 is fixedly connected with a pressing plate 6. The pressing plate 6 is accommodated in the working bin 2. In the middle of the top of the workbench 3, a mold 7 is fixed. A pipe 8 is placed on the upper end of the mold 7. The pressing plate 6 is located above the pipe 8. Two pipe pulling devices 9 for clamping the pipe 8 and driving the pipe 8 to move upward are installed on the workbench 3. The two pipe pulling devices 9 are respectively located on the left and right sides of the pipe 8. The upper middle part of the mold 7 is conical.

[0015] As Figure 1 shown, in order to enable the pressing plate 6 to move up and down stably, columns 10 extending vertically are fixed at both left and right ends of the top of the workbench 3. Sliding sleeves 11 are fixed at both left and right ends of the pressing plate 6. The columns 10 pass through the sliding sleeves 11, and the sliding sleeves 11 are in sliding fit with the columns 10 up and down.

[0016] As shown Figure 1 In order to facilitate the installation of the tube pulling device 9, brackets 12 are fixed to both the left and right ends of the top of the workbench 3, and the tube pulling device 9 is fixedly connected to the brackets 12.

[0017] As shown Figure 1 and Figure 2 In the figure, the tube pulling device 9 includes a first slide cylinder 91 fixedly arranged at the top of the bracket 12 and extending left and right. A first connecting plate 92 is fixed to the end of the first slide 911 at the upper end of the first slide cylinder 91. A second slide cylinder 93 extending up and down is fixed to the outside of the first connecting plate 92. A second connecting plate 94 is fixed to the top of the second slide 931 on the outside of the second slide cylinder 93. A pneumatic claw 95 is fixed to the top of the second connecting plate 94. A through hole (through hole) penetrating up and down is provided on the workbench 3, which facilitates the movement of the lower end of the second slide cylinder 93. The two pneumatic claws 95 are respectively located on the left and right sides of the pipe 8. The first slide cylinder 91 is used to control the left and right movement of the pneumatic claw 95, the second slide cylinder 93 is used to control the up and down movement of the pneumatic claw 95, and the pneumatic claw 95 is used to clamp the pipe 8.

[0018] Before detection, first place the pipe 8 on the upper end of the mold 7, and then the oil cylinder 4 controls the pressing plate 6 to move downward. The pressing plate 6 presses the pipe 8 downward to flare the lower end of the pipe 8. After the flaring is completed, the oil cylinder 4 controls the pressing plate 6 to reset. The second slide cylinder 93 controls the pneumatic claw 95 to move upward by a certain distance. The first slide cylinder 91 controls the pneumatic claw 95 to approach the pipe 8, and then the two pneumatic claws 95 clamp the pipe 8. The second slide cylinder 93 controls the pneumatic claw 95 to move upward again, so that the pneumatic claw 95 can pull the pipe 8 upward, separating the pipe 8 from the mold 7. After separation, the pneumatic claw 95 releases the pipe 8, and then the pipe 8 can be taken away manually. The worker first observes whether the pipe at the flared part is cracked, and there is no need for the worker to pull the pipe 8 upward, which saves time and effort and improves work efficiency.

[0019] Of course, the above is only the preferred embodiment of the present invention, and thus does not limit the patent scope of the present invention. Any simple modification and equivalent structural changes made by using the content of the specification and drawings of the present invention should be equally included in the patent protection scope of the present invention.
