Description

Technical Field

[0001] This utility model relates to the field of upsetting machines, specifically a push plate structure for a cylinder upsetting device with a high-pressure hydraulic cylinder. Background Technology

[0002] Upsetting and pressing straight thread connection technology uses a special upsetting machine to pre-upset the threaded section at the end of the steel bar, making the diameter of the upset part larger than the diameter of the base material. Then, a matching special threading machine is used to thread the upset part. Finally, a sleeve of the same specification is used to connect the threaded parts of the two steel bars with a wrench, thus completing the so-called steel bar butt connection.

[0003] In the existing technology, the upsetting machine has a hydraulic cylinder inside. The hydraulic cylinder pushes the end of the steel bar to be upset under a specific pressure. However, when the steel bar is placed inside the upsetting machine, it lacks a positioning function, which makes the steel bar unstable and prone to displacement. This leads to uneven stress on the steel bar during upsetting. Utility Model Content

[0004] To address the shortcomings of existing technologies, which lack positioning functions when reinforcing bars are placed inside the upsetting machine, resulting in instability and easy displacement of the reinforcing bars, and consequently uneven stress on the reinforcing bars during upsetting, this utility model proposes a push plate structure for a cylinder body upsetting device using a high-pressure hydraulic cylinder.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a push plate structure for a cylinder upsetting device of a high-pressure hydraulic cylinder, including an upsetting machine, wherein a positioning mechanism is provided on the top of the upsetting machine;

[0006] The positioning mechanism includes a base plate, the top of which is slidably connected to the top of the upsetting machine. A support rod is fixedly connected to the top of the base plate, and a hollow disc is fixedly connected to the top of the support rod. A rotating disk is rotatably connected to the inner cavity of the hollow disc. A planar threaded block is fixedly connected to one side of the rotating disk, and a positioning block is provided on one side of the planar threaded block. A limit groove is formed on the surface of the hollow disc, and the top of the positioning block is slidably connected to the inner cavity of the limit groove.

[0007] Preferably, a cylinder is fixedly connected to one side of the upsetting machine, a push plate is fixedly connected to one side of the cylinder, and one side of the push plate is fixedly connected to one side of the base plate.

[0008] Preferably, a first gear is fixedly connected to one side of the rotating disk, a placement groove is formed on the surface of the hollow disk, a second gear is provided in the inner cavity of the placement groove, the teeth of the second gear mesh with the teeth of the first gear, a crank is fixedly connected to one side of the hollow disk, and one side of the second gear is rotatably connected to one side of the crank.

[0009] Preferably, the surface of the positioning block is provided with a hollow groove, and a T-shaped rod is provided in the inner cavity of the hollow groove. One side of the T-shaped rod is fixedly connected to one side of the hollow disc.

[0010] Preferably, the surface of the rotating disk is provided with a mounting groove, and the inner cavity of the mounting groove is rotatably connected to a ball bearing.

[0011] Preferably, a fixing block is fixedly connected to one side of the base plate, a reinforcing rod is fixedly connected to the top of the fixing block, and one side of the reinforcing rod is fixedly connected to one side of the hollow disc.

[0012] Preferably, a hollow block is fixedly connected to the surface of the hollow disk, and a threaded rod is threadedly connected to the inner cavity of the hollow block.

[0013] Preferably, a rubber block is fixedly connected to one side of the positioning block, and several rubber blocks are provided.

[0014] Compared with existing technologies, this invention allows the reinforcing bar to be upset to pass through the middle part of a hollow disc and move into the upsetting machine. Then, the second gear rotates, driving the first gear to rotate. The first gear, in turn, drives the planar threaded block to rotate via the rotating disc. The planar threaded block then moves multiple positioning blocks to clamp the reinforcing bar, ensuring its stability within the hollow disc and the upsetting machine. This makes the reinforcing bar less prone to shifting during upsetting, resulting in better upsetting performance. After upsetting, the cylinder is activated, moving the push plate and the base plate. The base plate then moves the hollow disc and the reinforcing bar together, allowing the reinforcing bar to be smoothly removed from the upsetting machine. This prevents the reinforcing bar from being difficult to pull out due to rust on its surface. This invention solves the problem of insufficient positioning function when the reinforcing bar is placed inside the upsetting machine, leading to instability, easy shifting, and uneven stress during upsetting.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a pusher plate structure for a cylinder upsetting device of a high-pressure hydraulic cylinder. (Refer to...) Figure 1-5 A push plate structure for a high-pressure hydraulic cylinder upsetting device includes an upsetting machine 1. A positioning mechanism 2 is provided on the top of the upsetting machine 1. The interior of the upsetting machine 1 can be used to place the steel bars that need to be upset. The upsetting machine 1 can also smoothly upset the steel bars through the internal high-pressure hydraulic cylinder. The positioning mechanism 2 is located at the entrance of the upsetting machine 1 and can position the steel bars inside the upsetting machine 1, making the steel bars less prone to displacement and more stable.

[0025] The positioning mechanism 2 includes a base plate 201, the top of which is slidably connected to the top of the upsetting machine 1. A support rod 202 is fixedly connected to the top of the base plate 201. A hollow disc 203 is fixedly connected to the top of the support rod 202. A rotating disc 204 is rotatably connected to the inner cavity of the hollow disc 203. A flat threaded block 205 is fixedly connected to one side of the rotating disc 204. A positioning block 206 is provided on one side of the flat threaded block 205. A limiting groove 207 is opened on the surface of the hollow disc 203. The top of the positioning block 206 is slidably connected to the inner cavity of the limiting groove 207.

[0026] The base plate 201 supports the support rod 202, which in turn connects to the hollow disc 203, allowing the hollow disc 203 to be stably positioned on one side of the upsetting machine 1. Simultaneously, the center of the hollow disc 203 is aligned with the rebar inlet of the upsetting machine 1. The rotating disc 204 can rotate inside the hollow disc 203, and its rotation drives the planar threaded block 205 to rotate as well. The positioning block 206 is threadedly connected to the planar threaded block 205, allowing the planar threaded block 205 to move along with it as it rotates. The limiting groove 207... The positioning block 206 can be limited, allowing it to move smoothly when the planar threaded block 205 rotates. Multiple positioning blocks 206 can be provided, enabling simultaneous movement. Once moved, these blocks clamp the reinforcing bar, stabilizing it within the hollow disc 203 and the upsetting machine 1. This ensures greater stability and prevents displacement of the reinforcing bar during upsetting by the upsetting machine 1. Furthermore, the movable nature of the positioning block 206 allows for the positioning of reinforcing bars of varying thicknesses within the hollow disc 203, resulting in better performance.

[0027] Reference Figure 1 A cylinder 3 is fixedly connected to one side of the upsetting machine 1, and a push plate 4 is fixedly connected to one side of the cylinder 3. One side of the push plate 4 is fixedly connected to one side of the base plate 201. The cylinder 3 is located on one side of the upsetting machine 1, and the push plate 4 can connect the cylinder 3 and the base plate 201, so that the cylinder 3 can drive the base plate 201 to move on the upper side of the upsetting machine 1 through the push plate 4. At the same time, it can also drive the hollow disc 203 and the steel bar to move together, thereby achieving the effect of pushing the steel bar out of the inside of the upsetting machine 1. This makes the removal of the steel bar smoother and will not cause the steel bar to be difficult to pull out due to the rust on the surface of the steel bar.

[0028] Reference Figure 3 A first gear 5 is fixedly connected to one side of the rotating disk 204. A placement groove 8 is provided on the surface of the hollow disk 203. A second gear 6 is provided in the inner cavity of the placement groove 8. The teeth of the second gear 6 mesh with the teeth of the first gear 5. A crank 7 is fixedly connected to one side of the hollow disk 203. One side of the second gear 6 is rotatably connected to one side of the crank 7. The first gear 5 is connected to one side of the rotating disk 204. The second gear 6 can be placed inside the placement groove 8 so that the second gear 6 can be connected to the first gear 5. At this time, the second gear 6 can drive the first gear 5 and the rotating disk 204 to rotate together by rotating. This makes the rotation of the rotating disk 204 more convenient. The crank 7 can support the second gear 6 so that the second gear 6 can be stably placed on one side of the first gear 5.

[0029] Reference Figure 2The surface of the positioning block 206 is provided with a hollow groove 9, and a T-shaped rod 10 is provided in the inner cavity of the hollow groove 9. One side of the T-shaped rod 10 is fixedly connected to one side of the hollow disc 203. The interior of the hollow groove 9 can be used to place the T-shaped rod 10, and the T-shaped rod 10 can limit the positioning block 206 through the hollow groove 9, making the positioning block 206 more stable inside the limiting groove 207 and less likely to fall out of the limiting groove 207.

[0030] Reference Figure 4 The surface of the rotating disk 204 is provided with a mounting groove 11. The inner cavity of the mounting groove 11 is rotatably connected to a ball bearing 12. The inside of the mounting groove 11 can be used to install the ball bearing 12, and the ball bearing 12 can reduce the friction of the rotating disk 204 rotating inside the hollow disk 203, so that the rotating disk 204 rotates more smoothly and is less likely to cause a feeling of blockage.

[0031] Reference Figure 1 A fixing block 13 is fixedly connected to one side of the base plate 201, and a reinforcing rod 14 is fixedly connected to the top of the fixing block 13. One side of the reinforcing rod 14 is fixedly connected to one side of the hollow disc 203. The fixing block 13 can be used to connect the reinforcing rod 14, and the reinforcing rod 14 can be connected to the hollow disc 203, making the hollow disc 203 more secure on the top of the support rod 202 and less prone to breakage and deformation.

[0032] Reference Figure 2 A hollow block 15 is fixedly connected to the surface of the hollow disc 203. A threaded rod 16 is threadedly connected to the inner cavity of the hollow block 15. The interior of the hollow block 15 can be used to place the threaded rod 16. The threaded rod 16 can move by rotating inside the hollow block 15. After the threaded rod 16 moves, it will squeeze the second gear 6, making the second gear 6 difficult to rotate. This makes it difficult for the rotating disc 204 and the positioning block 206 to move, making the clamping of the reinforcing bar by the positioning block 206 more stable.

[0033] Reference Figure 2 A rubber block 17 is fixedly connected to one side of the positioning block 206. Several rubber blocks 17 are provided. The curved rod 7 can replace the positioning block 206 to contact the reinforcing bar, thereby increasing the friction between the positioning block 206 and the reinforcing bar, making the reinforcing bar more stable.

[0034] Working principle: When using this device, the steel bar to be upset is first passed through the middle part of the hollow disc 203 and moved into the upsetting machine 1. Then, the second gear 6 is rotated, driving the first gear 5 to rotate. The first gear 5 then drives the rotating disc 204 to rotate, and the rotating disc 204 drives the planar threaded block 205 to rotate as well. Afterward, the planar threaded block 205 drives multiple positioning blocks 206 to slide inside the limiting groove 207. When the multiple positioning blocks 206 move to their positions, they clamp the steel bar, making the steel bar stable inside the hollow disc 203 and the upsetting machine 1. This allows the upsetting machine to... 1. When upsetting reinforcing bars, the reinforcing bars are less likely to shift and are more stable, resulting in a better upsetting effect. After the reinforcing bars are upset, the cylinder 3 is activated to move the push plate 4. The push plate 4 will move the base plate 201, and the base plate 201 will move the hollow disc 203 and the reinforcing bars together, allowing the reinforcing bars to be smoothly removed from the inside of the upsetting machine 1. This will prevent the reinforcing bars from being difficult to pull out due to the rust on the surface of the reinforcing bars. This solves the problem that when the reinforcing bars are placed inside the upsetting machine 1, the lack of positioning function leads to instability and easy shifting of the reinforcing bars, which in turn leads to uneven stress on the reinforcing bars during upsetting.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
