Description

Technical Field

[0001] The invention relates to the technical field of production of perforating ammunition liner for oil and gas wells, in particular to a powder spinning device for a liner. Background Art

[0002] The liner is a product manufactured by powder metallurgy, which is characterized by the fact that the liner is made entirely of metal powder metallurgy composite materials. With the deepening of research, composite liners (such as tungsten-copper alloy) have emerged. They combine metals or alloys with different properties according to the design requirements of the liner to give full play to their comprehensive advantages. Compared with single metal liners, its energy conversion and absorption mechanism is more reasonable, the utilization rate of chemical energy is more sufficient, the armor-piercing performance is better, and the cost is lower, so it has broad development prospects. Liners are widely used in oil drilling, mining, national defense and other fields. In oil drilling, the liner, as the core component of the perforating bullet, plays a vital role in the quality of perforation. Therefore, the quality of the liner often determines the performance of the perforating bullet.

[0003] At present, the production of medicine caps mainly includes the steps of powder mixing, pressing, heat treatment, etc., wherein the pressing part mainly adopts the powder spinning molding method. When the metal powder rotates in the mold, a four-column hydraulic press is used to suddenly apply huge pressure to it to make it form instantly. However, the existing technology generally adopts a bevel gear connected to the motor in the vertical direction, and a spur gear meshing with the bevel gear in the horizontal direction. This method has a small torque, resulting in that after the motor rotates, the gear speed is limited, which in turn leads to limited rotation of the mold, making the mold less stable in rotation, easily leading to uneven distribution of powder in the mold, and inconvenient to remove the material.

[0032] According to the technical solution of this embodiment, a slot matching with the matching head 12 is provided on the top of the floating joint 11, and the matching head 12 is stuck in the slot to realize a detachable connection between the two. The function of the floating joint 11 is to connect the cylinder and the push rod 5.

[0033] According to the technical solution of this embodiment, the top end of the optical axis 2 is sleeved with a bushing 20, and the top end of the bushing 20 is fixedly connected with a guide shaft support 13. The optical axis 2 passes through the guide shaft support 13, and the guide shaft support 13 is used to fix it with the press above by bolts, and can also fix the optical axis 2 on both sides.

[0034] For the technical solution of this embodiment, Figure 1 and Figure 2 As shown, there are two optical axes 2, and the two optical axes 2 are respectively fixedly connected with a clamp 14 and a clamp 15 by bolts.

The motor mounting plate 16 is sleeved on the optical axis 2, and a servo motor 17 is fixedly connected to the motor mounting plate 16. The output shaft of the servo motor 17 passes through the motor mounting plate 16. The motor mounting plate 16 can be fixed on the optical axis 2 by using the clamp 14 and the clamp 15 arranged in two sections, so as to provide support for the servo motor 17. It should be noted that the servo motor 17 is powered by an external power supply.

[0035] For the technical solution of this embodiment, Figure 4As shown, the bearing seat assembly 4 includes a shell 41 fixedly connected to the bearing seat mounting plate 3, the interior of the shell 41 is rotatably connected to a sleeve 42, a push rod 5 is installed in the sleeve 42, and the sleeve 42 is fixedly connected to a bushing 7, and the bearing seat is mainly used to provide support and guidance for the push rod 5.

[0036] Furthermore, a bushing 2 18 is fixedly connected to the output shaft of the servo motor 17, and the driving wheel 9 is fixedly connected to the output shaft of the servo motor 17 through the bushing 2 18. Starting the servo motor 17 drives the bushing 2 18 to rotate, thereby driving the driving wheel 9 to rotate.

[0038] Furthermore, a latch is used to detachably connect the push rod 1 5 and the push rod 2 6, so that the push rod 1 5 and the push rod 2 6 can be easily disassembled or replaced. When the push rod 1 5 rotates, the push rod 2 6 will also rotate. The push rod 2 6 is connected to the mold by bolts. Therefore, when the push rod 2 6 rotates, the mold can also rotate with it. The rotation stability is higher, which is beneficial to improve the distribution of powder in the mold, make the metal powder rotate more fully, and effectively improve the consistency of product quality.
