Description

Combined slotted screen tube laser processing equipment and processing method

Technical Field

The present invention relates to the field of screen pipe processing, and more specifically, to a laser processing device and a processing method for a combined seam screen pipe.

Background Art

Combined slotted screen pipe is an advanced oil production tool used to improve oil production efficiency and reduce sand plugging problems. Screen pipes are divided into wire wound screen pipes and slotted screen pipes according to different processing methods. In the process of oil production, different steel grades and types of screen pipes need to be selected according to the geological environment of the oil well. Among them, slotted screen pipes have many advantages such as high strength and recovery rate, small flow resistance and strong adaptability, and have been widely used.

The slot types of slotted screen pipes mainly include rectangular slots, trapezoidal slots and special-shaped holes. The combined slot screen pipe needs to combine and arrange multiple slots to improve the efficiency and safety of oil production. During the cutting process of the combined slot screen pipe, it is necessary to evenly cut multiple slots on the outer surface of the screen pipe. During the laser cutting process, in order to ensure the cutting accuracy of the combined slot, the screen pipe needs to be clamped and fixed to reduce the probability of accidental movement during the cutting process of the screen pipe.

When the existing screen tube laser processing equipment is working, the screen tube is usually magnetically fixed on the surface of the cutting table to achieve quick clamping and fixing of the screen tube. However, during the cutting process, the surface of the screen tube needs to be cut evenly, so the position of the screen tube needs to be flexibly adjusted to achieve uniform cutting. Although the existing laser processing equipment can quickly clamp the screen tube when working, the axial position of the screen tube will be offset when the position of the screen tube is adjusted, thereby affecting the accuracy of the screen tube cutting position, and the position of the screen tube needs to be readjusted and corrected during the second clamping, thereby reducing the screen tube cutting efficiency to a certain extent.

Please refer to Figures 1 to 10, a combined seam screen tube laser processing equipment includes a support rod 37, a movable groove 39 is embedded in the inner side of the support rod 37, a movable rod 391 is rotatably connected to the outer surface of the support rod 37, the support rod 37 is rotatably connected to the movable rod 391 through the movable groove 39, and a support rod 38 is rotatably connected to the movable rod 391 through the support rod 37, and a clamping assembly is provided on the outer surfaces of the support rod 37 and the support rod 38;

The clamping assembly includes a second pin 44 fixedly connected to the outer surfaces of the first support rod 37 and the second support rod 38 respectively, the outer surface of the second pin 44 is rotatably connected to a pull rod 45, the end of the pull rod 45 away from the second pin 44 is rotatably connected to a support rod 46, the outer surface of the support rod 46 is fixedly connected to a bearing 47, and the outer surface of the bearing 47 is rotatably connected to a support wheel 48 for lifting and supporting the screen pipe 49;

The outer surfaces of the support rod 1 37 and the support rod 2 38 are fixedly connected with a bracket 41, the inner side of the bracket 41 is fixedly connected with a pin shaft 1 42, the outer surface of the pin shaft 1 42 is rotatably connected with an extrusion wheel 43, and the extrusion wheel 43 is in rotational contact with the outer surface of the screen tube 49.

The number of the support rod 1 37 and the support rod 2 38 is two groups and they are symmetrically distributed. The extrusion wheel 43 is made of wear-resistant material. The middle part of the outer surface of the support rod 46 is rotatably connected with a positioning wheel 491, and the positioning wheel 491 is in rotational contact with the lower side of the outer surface of the screen tube 49.

By adopting the above technical solution, when the combined seam screen tube 49 is cut and processed, in order to ensure the combined seam cutting processing accuracy, the screen tube 49 needs to be clamped to keep the screen tube 49 stable during the cutting process, and the support rod 1 37 and the support rod 2 38 can rotate with the movable rod 391 as the fulcrum. After the screen tube 49 is placed on the upper side of the supporting wheel 48, the support rod 1 37 and the support rod 2 38 are rotated so that the support rod 1 37 and the support rod 2 38 are close to each other. At this time, the support rod 1 37 and the support rod 2 38 will pass The bracket 41 and the pin shaft 1 42 drive the extrusion wheel 43 to move synchronously, so that the two groups of extrusion wheels 43 are attached to the outer surface of the screen tube 49, so that the screen tube 49 is clamped and positioned by the extrusion wheel 43 and the supporting wheel 48. During the rotation process, the support rod 1 37 and the support rod 2 38 will drive the pull rod 45 to move synchronously through the pin shaft 2 44.

A fixed seat 31 is arranged on the outside of the movable block 34, and the movable block 34 is located on the inside of the fixed seat 31 and is slidably connected to the inner surface of the fixed seat 31. A screw 32 is rotatably connected to the inner side of the fixed seat 31, and the outer surface of the screw 32 is symmetrically provided with positive threads and negative threads. The screw 32 is spirally connected to the two groups of movable seats 16, and a knob 33 is fixedly connected to the left end of the screw 32, and the outer surface of the lower end of the fixed seat 31 is fixedly connected to the workbench 11.

By adopting the above technical scheme, the workbench 11 lifts and supports the fixed seat 31. When the support rod 1 37 and the support rod 2 38 are moved, in order to make the support rod 1 37 and the support rod 2 38 move synchronously and improve the clamping stability of the screen tube 49, a support assembly is set. During operation, the operator drives the screw rod 1 32 to rotate through the knob 33, and the two groups of movable blocks 34 are respectively connected by the positive thread and the negative thread spiral transmission on the outer surface of the screw rod 1 32. As the screw rod 1 32 rotates, the two groups of movable blocks 34 are driven to move synchronously towards each other. The movable blocks 34 drive the baffle plates 35 to move synchronously during the movement. The two groups of baffle plates 35 are respectively rotatably connected to the support rod 1 37 and the support rod 2 38 through the pin rod 36. During the movement, the support rod 1 37 and the support rod 2 38 are driven to rotate with the pin shaft 1 42 as the fulcrum, thereby driving the clamping assembly to quickly clamp and fix the screen tube 49.

As shown in Figures 1 and 10, a positioning assembly is provided on the front side of the screen tube 49, and the positioning assembly includes a mounting plate 51 fixedly connected to the outer surface of the upper end of the workbench 11, and a motor 52 is fixedly connected to the outer surface of the front end of the mounting plate 51. The output shaft of the motor 52 passes through the rear side of the mounting plate 51 and is rotatably connected to the mounting plate 51, and a screw rod 53 is fixedly connected to the rear end of the output shaft of the motor 52.

The outer surface of the second screw 53 is symmetrically fixedly connected with a connecting block 54, and the connecting block 54 is fixedly connected with a fixing rod 55 at one end away from the second screw 53. The fixing rod 55 is in a circular ring shape, and the outer surface of the fixing rod 55 is rotatably connected with a contact rod 57. The number of the contact rods 57 is several groups and distributed in a ring array. The outer surface of the second screw 53 is spirally connected with a spiral seat 56, and the outer surface of the spiral seat 56 is in movably contact with the contact rod 57, and the contact rod 57 is in contact with the inside of the screen tube 49.

By adopting the above technical solution, during the processing, the screen tube 49 needs to be evenly rotated so that the surface of the screen tube 49 can be evenly cut with a combined seam. In order to adjust the rotation speed and position of the screen tube 49, a positioning component is set. When the positioning component is working, the front end of the screen tube 49 is first placed on the outside of the contact rod 57, and then the operator rotates the spiral seat 56. The spiral seat 56 is connected to the spiral transmission of the first screw rod 53 and moves synchronously toward the inside of the screen tube 49 during the rotation. The spiral seat 56 will slide in contact with the surface of the contact rod 57 during the movement. As the spiral seat 56 gradually moves, the spiral seat 56 will drive the contact rod 57 to squeeze and fit inside the screen tube 49, so that the screen tube 49 is clamped and positioned in the axial direction by the contact rod 57, thereby further improving the clamping and positioning accuracy of the screen tube 49 and reducing the In order to reduce the probability of accidental rotation during the cutting process, the screw rod 53 fixes and supports the fixing rod 55 through the connecting block 54, and the contact rod 57 can move the fixing rod 55 as a fulcrum for rotation. When the screen tube 49 needs to be rotated, the motor 52 is started and operated by the control system. The workbench 11 fixes and supports the motor 52 through the mounting plate 51. The output shaft of the motor 52 drives the screw rod 53 to rotate synchronously. The screw rod 53 drives the fixing rod 55 and the contact rod 57 to rotate synchronously through the connecting block 54. The friction between the contact rod 57 and the screen tube 49 drives the screen tube 49 to rotate, so that the outer surface of the screen tube 49 is evenly cut, thereby effectively improving the cutting accuracy of the screen tube 49. At the same time, the supporting wheel 48 and the extrusion wheel 43 can guide the rotation of the screen tube 49, thereby further improving the rotation stability of the screen tube 49.

By adopting the above technical solution, the workbench 11 supports the slide seat 13 by the slide rail 12, so that the slide seat 13 can slide linearly along the outer surface of the slide rail 12 under the action of external force, thereby driving the support seat 14 to move synchronously through the slide seat 13, and the movable seat 16 can slide linearly up and down along the outer surface of the support seat 14. When adjusting the position of the movable seat 16, the operator pulls the limit rod 17 to the front side, so that the limit rod 17 drives the limit plate 18 to slide out of the limit groove 181, and the limit rod 17 drives the clamping wheel 19 to disengage from the stop block 15.
