Description

Technical Field

[0001] This invention relates to the field of oil well downhole equipment manufacturing technology, and in particular to a cold press for embedding anchor claw alloys. Background Technology

[0002] In the manufacturing process of downhole tools (such as packers), the alloy mounting of the anchor claw is a critical technological step. The anchor claw consists of a carbide claw head and a steel body, and a high-precision interference fit must be achieved through a cold pressing process to ensure reliable anchoring in the high-pressure and high-wear environment downhole.

[0003] However, traditional cold pressing operations have some technical drawbacks. In existing methods, the anchor claw body is simply placed on the workbench support using a simple clamp or manually, lacking precise axial and circumferential positioning. During cold pressing, the mating surfaces of the claw head and the body are prone to stress concentration due to slight misalignment, leading to alloy cracking or steel deformation, which seriously affects the sealing performance and service life of the packer. Furthermore, traditional cold presses cannot reproduce precise pressing depths, resulting in large fluctuations in installation quality during mass production. Subsequent destructive testing (such as metallographic analysis) is required to screen qualified products, leading to material waste and low efficiency. Therefore, it is necessary to propose a cold press for anchor claw alloy installation to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cold press for embedding anchor claw alloys, so as to improve embedding accuracy, ensure process stability and eliminate safety hazards.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a cold press for embedding anchor claw alloy, comprising a base plate, a worktable fixedly mounted on the upper end of the base plate, an anchor claw body, a positioning component for placing the anchor claw body, and a cold pressing structure for processing the anchor claw body on the top of the worktable, a locking structure for fixing the anchor claw body on the positioning component, a support frame mounted on the worktable, two left and right support plates fixedly mounted on the upper end of the support frame, and a limiting component for fixing the positioning component on each of the two support plates, the locking structure comprising two circular holes on the upper end of the positioning component and a stop bar located at the top between the two circular holes, and inserts inserted into the circular holes fixedly mounted at both ends of the stop bar, a semi-circular limiting block adapted to the inserts being slidably mounted on one side of the positioning component located in the circular hole, a rack fixedly mounted on the side of the semi-circular limiting block away from the circular hole, a drive rod rotatably mounted on the positioning component, and a gear meshing with the rack fixedly mounted on the drive rod.

[0006] By adopting the above technical solution, the positioning component is placed between two support plates, and the positioning component can be firmly fixed by the limiting component. Then, the anchor claw body is placed on the corresponding position on the upper end of the positioning component. Next, the stop bar is installed on the anchor claw body, and the inserts at both ends are inserted into the round holes. By rotating the drive rod and gear, the rack is meshed and slides left and right, which can drive the semi-circular limiting block at the end to move, so that the semi-circular limiting block positions the insert, thereby locking the insert into the round hole. This allows the stop bar to press the anchor claw body tightly. When the claw head is pressed into the body later, the problem of positional displacement is avoided, the installation accuracy is greatly improved, and the stability of the process is guaranteed.

[0007] A further feature of the present invention is that: the positioning member is provided with a limiting groove for placing the anchor claw body; the bottom of the stop bar is fixedly fitted with a fixing post for abutting the anchor claw body; both the upper and lower sides of the rack are fixedly fitted with slide bars; the positioning member is provided with an opening for the rack and the semi-circular limiting block to slide left and right; and a sliding groove adapted to the slide bar is provided in the opening.

[0008] By adopting the above technical solution, the limiting groove can be used to place the anchor claw body. The fixing column is inserted into the anchor claw body and pressed down, so that the anchor claw body is stably locked. With the cooperation of the slide bar and the slide groove, the translation of the rack is more stable and the meshing effect between the gear and the rack is better.

[0009] A further embodiment of the present invention is that the positioning element includes an inner rod placed between two left and right support plates and a sleeve fixed to the outside of the inner rod.

[0010] By adopting the above technical solution, the two ends of the inner rod are respectively placed above the support plate. The limiting component can not only clamp the two ends of the inner rod, but also further press the sleeve, making the overall stability of the positioning component better and the precision of the anchor claw body installation higher.

[0011] A further feature of the present invention is that the limiting member includes three fixed wheels disposed on the upper end of the support plate and in close contact with the outer wall of the inner rod, and the support plate is also provided with a driving member for adjusting the position of the three fixed wheels, and anti-slip sleeves are installed on the outside of the three fixed wheels.

[0012] By adopting the above technical solution, the three fixed wheels can be controlled by the drive component to converge synchronously and clamp the end of the inner rod. The anti-slip sleeve can improve the stability of fixing the inner rod.

[0013] A further configuration of the present invention is as follows: the driving component includes two rotating shafts installed inside the support plate and a rotating frame rotatably connected to the support plate via the rotating shafts. A pulley is installed at the lower end of the rotating frame, a torsion spring is installed on the rotating shaft, and the fixed wheels on both sides are fixedly installed at the upper end of the rotating frame. A triangular block that pushes the rotating frame to rotate is also provided inside the support plate. The fixed wheel in the middle is fixedly installed at the top of the triangular block, and the pulley rolls on the side of the triangular block. A screw structure for controlling the up and down sliding of the triangular block is provided on the inner bottom wall of the support plate.

[0014] By adopting the above technical solution, the lead screw structure pushes the triangular block upward, causing the pulley to roll on the side slope. As the triangular block moves upward, the rotating frame rotates synchronously around the pivot, simultaneously driving the three fixed wheels to approach the inner rod and clamp it. The torsion spring ensures that the distance between the three fixed wheels is the greatest when the triangular block is at the bottom, thus making it easier to fix the inner rod.

[0015] A further configuration of the present invention is as follows: the lead screw structure includes a first lead screw and a rotating rod rotatably disposed at the bottom of the support plate, the end of the rotating rod is provided with a first bevel tooth, the bottom of the first lead screw is provided with a second bevel tooth adapted to the first bevel tooth, the triangular block is threadedly connected to the first lead screw, and the inner bottom wall of the support plate is also fixedly provided with two guide rods slidably connected to the triangular block.

[0016] By adopting the above technical solution, holding the end of the rotating rod and rotating the first bevel tooth can drive the second bevel tooth to rotate, causing the first lead screw to rotate. With the cooperation of the guide rod, the triangular block threaded to it moves upward stably, thereby controlling the three fixed wheels to come together and clamping the end of the inner rod.

[0017] A further feature of the present invention is that the limiting member further includes an arc-shaped frame rotatably mounted on the right support plate, the bottom of the arc-shaped frame is fixedly fitted with a push block for pressing the sleeve, and the support plate is also provided with a driving member for rotating the arc-shaped frame.

[0018] By adopting the above technical solution, the lower end of the arc-shaped frame is driven by the pusher to move closer to the sleeve, so that the pusher presses the sleeve tightly, which can position the sleeve and further improve the fixing effect of the positioning component.

[0019] A further configuration of the present invention is as follows: the pushing member includes a threaded block fixedly mounted on the bottom of the support plate and a second lead screw threadedly adapted to the threaded block; the upper end of the second lead screw is provided with a lifting frame slidably connected to the support plate; both ends of the lifting frame and the arc frame are hinged with push rods; and two guide rails slidably connected to the lifting frame are fixedly mounted on the side of the support plate.

[0020] By adopting the above technical solution, the end of the second lead screw is held and rotated, causing the second lead screw to rotate upward, pushing the lifting frame connected to it to rise, causing the push rod to tilt, pushing the arc frame to rotate, and pressing the sleeve tightly.

[0021] A further configuration of the present invention is as follows: the cold pressing structure includes a cold pressing host fixedly mounted on a workbench, a hydraulic cylinder installed inside the cold pressing host, a lifting plate installed at the output end of the hydraulic cylinder, a conical cold pressing head fixedly mounted at the lower end of the lifting plate, a connecting rod fixedly mounted at the right end, a scale provided at one end of the cold pressing host near the connecting rod, and a vernier adapted to the scale installed at the upper end of the connecting rod.

[0022] By adopting the above technical solution, the claw head is placed in the corresponding groove of the anchor claw body. The hydraulic cylinder drives the lifting plate and the conical cold pressing head to move down to perform the embedding operation on the anchor claw body. During the pressing process, the connecting rod drives the vernier to move down. By cooperating with the scale, the stroke of the conical cold pressing head can be monitored in real time, thereby accurately controlling its pressing depth and further improving its embedding accuracy.

[0023] A further provision of the present invention is that a control box is installed on one side of the cold pressing host, and clamps for fixing the support frame are provided on both sides of the top of the workbench.

[0024] By adopting the above technical solution, the control box is used to adjust and control the equipment, and the fixture can fix and disassemble the support frame, thereby facilitating the subsequent replacement of different workpieces and improving the applicability of the device. The fixture in this application has a very simple structure in the attached drawings and belongs to common known technical means, so this application will not describe it in detail.

[0025] The beneficial effects of this invention are:

[0026] 1. This invention involves placing the anchor claw body on a positioning component, then attaching a stop bar to the anchor claw body, with the inserts at both ends inserted into circular holes. By rotating the drive rod and gear, the rack is engaged and slides left and right, which moves the semi-circular limiting block at the end, positioning the insert and locking it into the circular hole. This allows the stop bar to press against the anchor claw body, preventing positional shifts when the claw head is subsequently pressed into the body, greatly improving the installation accuracy and ensuring process stability.

[0027] 2. In this invention, the inner rod is placed on the support plates at both ends, and the triangular block is pushed upward by the screw structure, causing the pulley to roll on the side slope. As the triangular block moves upward, the rotating frame rotates synchronously around the pivot, simultaneously driving the three fixed wheels to approach and clamp the inner rod. The torsion spring ensures that the distance between the three fixed wheels is the greatest when the triangular block is at the bottom, thus making it easier to fix the inner rod and improving the fixing effect of the positioning component, thereby resulting in higher installation accuracy of the subsequent anchor claw body.

[0028] 3. In this invention, by holding the end of the second lead screw and rotating it, the second lead screw rotates upward, pushing the lifting frame connected to it to rise, causing the push rod to tilt, pushing the arc frame to rotate, pressing the sleeve, and further positioning the positioning component to ensure that it will not have a misalignment problem when subjected to high-intensity pressure.

[0029] 4. In this invention, the claw head is placed in the groove corresponding to the anchor claw body, and the lifting plate and the conical cold pressing head are driven by the hydraulic cylinder to move down to perform the embedding operation on the anchor claw body. During the pressing process, the connecting rod drives the vernier to move down. By cooperating with the scale, the stroke of the conical cold pressing head can be monitored in real time, thereby accurately controlling its pressing depth and further improving its embedding accuracy.

[0042] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1-6As shown, a cold press for embedding anchor claw alloys includes a base plate 1. A worktable 2 is fixedly mounted on the upper end of the base plate 1. An anchor claw body 3, a positioning component 4 for placing the anchor claw body 3, and a cold pressing structure 5 for processing the anchor claw body 3 are arranged on the top of the worktable 2. The positioning component 4 is provided with a locking structure 6 for fixing the anchor claw body 3. A support frame 7 is installed on the worktable 2. Two left and right support plates 8 are fixedly mounted on the upper end of the support frame 7. Each of the two support plates 8 is provided with a mechanism for fixing the positioning component 4. The positioning member 9 is a fixed limiting member. The locking structure 6 includes two circular holes on the upper end of the positioning member 4 and a stop bar 61 located at the top between the two circular holes. Both ends of the stop bar 61 are fixedly fitted with inserts 62 that are inserted into the circular holes. The positioning member 4 has a semi-circular limiting block 63 that is adapted to the inserts 62 slidably arranged on one side of the circular holes. The semi-circular limiting block 63 has a rack 64 fixedly installed on the side away from the circular holes. The positioning member 4 has a drive rod 65 rotatably arranged on it. The drive rod 65 has a gear 66 that meshes with the rack 64.

[0044] Positioning element 4 is placed between two support plates 8, and the positioning element 9 can firmly fix the positioning element. Then, the anchor claw body 3 is placed on the corresponding position on the upper end of the positioning element 4. Next, the stop bar 61 is installed on the anchor claw body 3, and the inserts 62 at both ends are inserted into the round holes. By rotating the drive rod 65 and the gear 66, the rack 64 is meshed and slides left and right, which can drive the semi-circular limit block 63 at the end to move, so that the semi-circular limit block 63 positions the insert 62, thereby locking the insert 62 into the round hole. This allows the stop bar 61 to press the anchor claw body 3 tightly. When the claw head is pressed into the body later, the problem of position displacement is avoided, which greatly improves the installation accuracy and ensures the stability of the process.

[0045] like Figure 4 , Figure 5 , Figure 6 As shown, the positioning member 4 is provided with a limiting groove for placing the anchor claw body 3, the bottom of the stop bar 61 is fixedly fitted with a fixing post 67 for pressing against the anchor claw body 3, the upper and lower sides of the rack 64 are both fixedly fitted with slide bars 68, the positioning member 4 is provided with an opening for the rack 64 and the semi-circular limiting block 63 to slide left and right, and a sliding groove adapted to the slide bar 68 is provided in the opening.

[0046] The limiting groove can be used to place the anchor claw body 3. The fixing column 67 is inserted into the anchor claw body 3 and pressed down to make the anchor claw body 3 stably locked. With the cooperation of the slide bar 68 and the slide groove, the translation of the rack 64 is more stable, and the meshing effect between the gear 66 and the rack 64 is better.

[0047] like Figure 4As shown, the positioning component 4 includes an inner rod 41 placed between the left and right support plates 8 and a sleeve 42 fixed to the outside of the inner rod 41; the two ends of the inner rod 41 are respectively placed above the support plates 8. The limiting component 9 can not only clamp the two ends of the inner rod 41, but also further press the sleeve 42, so that the overall stability of the positioning component 4 is better and the precision of the anchor claw body 3 is higher.

[0048] like Figure 7 , Figure 8 As shown, the limiting member 9 includes three fixed wheels 91 disposed on the upper end of the support plate 8 and tightly attached to the outer wall of the inner rod 41. The support plate 8 also contains a driving component for adjusting the position of the three fixed wheels 91. Anti-slip sleeves are installed on the exterior of each of the three fixed wheels 91. The driving component includes two rotating shafts 92 installed inside the support plate 8 and a rotating frame 93 rotatably connected to the support plate 8 via the rotating shafts 92. A pulley 94 is installed at the lower end of the rotating frame 93, and a torsion spring 95 is installed on the rotating shafts 92. The fixed wheels 91 located on both sides are fixedly mounted on the upper end of the rotating frame 93. The support plate 8 also contains a mechanism for pushing the rotating frame 93 to rotate. The triangular block 96 has a fixed wheel 91 fixedly mounted on its top, and a pulley 94 rolling on its side. The inner bottom wall of the support plate 8 is provided with a screw structure for controlling the up and down sliding of the triangular block 96. The screw structure includes a first screw 97 and a rotating rod 98 rotatably mounted on the bottom of the support plate 8. The end of the rotating rod 98 is equipped with a first bevel tooth 99, and the bottom of the first screw 97 is equipped with a second bevel tooth 910 that matches the first bevel tooth 99. The triangular block 96 is threadedly connected to the first screw 97. The inner bottom wall of the support plate 8 is also fixedly equipped with two guide rods 911 that are slidably connected to the triangular block 96.

[0049] The three fixed wheels 91 can be controlled by the drive unit to synchronously converge and clamp the end of the inner rod 41. The anti-slip sleeve can improve the stability of fixing the inner rod 41. The lead screw structure pushes the triangular block 96 upward, so that the pulley 94 rolls on the side slope. As the triangular block 96 moves upward, the rotating frame 93 rotates synchronously around the rotating shaft 92, which drives the three fixed wheels 91 to move closer to the inner rod 41 and clamp it. The torsion spring 95 ensures that the distance between the three fixed wheels 91 is the farthest when the triangular block 96 is at the bottom, which makes it easier to fix the inner rod 41. Holding the end of the rotating rod 98 and rotating the first bevel tooth 99 can drive the second bevel tooth 910 to rotate, so that the first lead screw 97 rotates. With the cooperation of the guide rod 911, the triangular block 96, which is threaded to it, moves upward stably, thereby controlling the three fixed wheels 91 to move closer and clamp the end of the inner rod 41.

[0050] like Figure 9As shown, the limiting member 9 also includes an arc-shaped frame 912 rotatably mounted on the right support plate 8. The bottom of the arc-shaped frame 912 is fixedly fitted with a push block 913 that presses the sleeve 42. The support plate 8 is also provided with a driving member for rotating the arc-shaped frame 912. The driving member includes a threaded block 914 fixedly mounted on the bottom of the support plate 8 and a second lead screw 915 threadedly adapted to the threaded block 914. The upper end of the second lead screw 915 is provided with a lifting frame 916 slidably connected to the support plate 8. Push rods 917 are hinged at both ends between the lifting frame 916 and the arc-shaped frame 912. The side of the support plate 8 is fixedly fitted with two guide rails 918 slidably connected to the lifting frame 916.

[0051] The lower end of the arc frame 912 is driven by the pusher to move closer to the sleeve 42, so that the push block 913 presses the sleeve 42, which can position the sleeve 42 and further improve the fixing effect of the positioning member 4; the end of the second lead screw 915 is grasped and rotated, so that the second lead screw 915 rotates upward, pushing the lifting frame 916 connected to it to rise, so that the push rod 917 tilts, pushing the arc frame 912 to rotate, and pressing the sleeve 42.

[0052] like Figure 10 As shown, the cold pressing structure 5 includes a cold pressing host 51 fixed on the workbench 2. A hydraulic cylinder 52 is installed inside the cold pressing host 51. A lifting plate 53 is installed at the output end of the hydraulic cylinder 52. A conical cold pressing head 54 is fixed at the lower end of the lifting plate 53, and a connecting rod 55 is fixed at the right end. A scale 56 is provided at one end of the cold pressing host 51 near the connecting rod 55. A vernier 57 adapted to the scale 56 is installed at the upper end of the connecting rod 55. A control box 10 is installed on one side of the cold pressing host 51. Clamps 11 for fixing the support frame 7 are provided on both sides of the top of the workbench 2.

[0053] The claw head is placed in the corresponding slot of the anchor claw body 3. The hydraulic cylinder 52 drives the lifting plate 53 and the conical cold pressing head 54 to move down to perform the embedding operation on the anchor claw body 3. During the pressing process, the connecting rod 55 drives the vernier 57 to move down. Through cooperation with the scale 56, the stroke of the conical cold pressing head 54 can be monitored in real time, so as to accurately control its pressing depth and further improve its embedding accuracy. The control box 10 is used to adjust and control the equipment. The clamp 11 can fix and disassemble the support frame 7, so as to facilitate the subsequent replacement of different workpieces and improve the applicability of the device. The clamp 11 in this application has a very simple structure in the attached drawings and belongs to common known technical means, so this application will not describe it in detail.
