Description

Technical Field

[0001] This application relates to the field of elbow processing technology, specifically a servo hydraulic elbow hot pusher. Background Technology

[0002] Elbows are a common type of pipe fitting used in pipeline installation. They are used to connect pipes at bends to change the direction of the pipes. Elbows are made of materials such as cast iron, stainless steel, alloy steel, carbon steel, non-ferrous metals, and plastics. The manufacturing processes include plate welding, stamping, and hot pushing.

[0003] The working principle of the elbow in the hot forming process is as follows: the straight pipe is put into the elbow forming machine, and after being heated by the medium frequency heater, the straight pipe is bent into an elbow.

[0004] Currently, after the elbow hot pushing machine processes the elbows, the elbows are left to fall and accumulate. When the elbows are heated, they are easily dented and damaged when they collide with each other because their walls are relatively soft. This cannot effectively protect the elbows and leads to defects in the subsequent processing quality of the elbows.

[0005] Therefore, this application provides a servo hydraulic elbow hot pusher to solve the above problems. Utility Model Content

[0006] This application provides a servo hydraulic elbow hot pusher, which aims to solve the problems mentioned in the background art, such as the easy collision and damage to the outer wall of the elbow during material feeding.

[0007] To achieve the above objectives, this application provides the following technical solution: a servo hydraulic elbow hot pusher, comprising a processing table, a hydraulic hot pusher assembly fixedly mounted on the processing table, a medium-frequency heating device fixedly mounted on the processing table and adapted to the hydraulic hot pusher assembly, a workpiece sleeved on the hydraulic hot pusher assembly and passing through the medium-frequency heating device, a roller conveyor belt disposed below the processing table, and a buffer unloading mechanism disposed on the processing table.

[0008] The buffer feeding mechanism includes a receiving part located on the processing table below the medium-frequency heating equipment. One end of the receiving part is inserted into a rotating rod that is rotatably connected to the processing table. A spring is installed at the bottom of the receiving part, distinct from the rotating rod. The end of the receiving part away from the rotating rod is positioned above the roller conveyor belt. In operation, workpieces are placed one by one onto the mold of the hydraulic hot-push assembly. The hydraulic hot-push assembly pushes the workpieces on the mold through the medium-frequency heating equipment, forming a high-heat bent tube. As the high-heat bent tube falls, it lands on the receiving part. The pressure on the receiving part compresses the spring at its bottom, causing the receiving part to rotate slowly along the rotating rod, thus buffering the workpiece on the receiving part and conveying it to the roller conveyor belt. The roller conveyor belt then transports the workpiece to the next processing stage. This effectively prevents the high-heat bent tubes from colliding and piling up during feeding, ensuring the integrity of the bent tube wall, guaranteeing processing quality, and facilitating manual transfer of individual, continuously transported high-heat bent tubes, resulting in high safety.

[0009] Preferably, in order to ensure stable material receiving, the receiving part is designed with an inverted V shape, and a through-hole receiving groove is provided on the receiving part to limit the workpiece and complete the stable material feeding.

[0010] Preferably, in order to support the receiving part, a first connecting block is fixedly installed on the processing table, and a second connecting block is fixedly installed on the receiving part near the rotating rod. The rotating rod passes through the first connecting block and the second connecting block, and the first connecting block and the second connecting block are rotatably connected to the rotating rod, so as to facilitate the disassembly and assembly of the receiving part for inspection and maintenance.

[0011] Preferably, in order to connect the spring, a support plate is fixedly installed on the roller conveyor belt, a first receiving block adapted to the spring is fixedly installed on the support plate, a second receiving block adapted to the spring is fixedly installed at the bottom of the receiving part, the two ends of the spring are respectively sleeved on the first receiving block and the second receiving block, and the two ends of the spring are welded to the first receiving block and the second receiving block, so that it can stably support the receiving part and facilitate maintenance.

[0012] Preferably, for material unloading, the elbow hot pusher also includes an auxiliary separation mechanism set on the processing table for quickly detaching the bonded workpiece and causing it to fall onto the receiving part, so as to avoid affecting subsequent processing and improve processing efficiency.

[0013] Preferably, for material unloading, the auxiliary separation mechanism includes a cylinder fixedly mounted on the processing table. The output end of the cylinder is aligned with the axial extension direction of the hydraulic hot push assembly. A C-shaped push rod adapted to the outer wall surface of the workpiece is fixedly mounted at the output end of the cylinder, thereby accelerating the unloading of the bent pipe and ensuring processing efficiency.

[0014] This elbow hot pushing machine places workpieces one by one onto the mold of the hydraulic hot pushing component. The hydraulic hot pushing component pushes the workpieces on the mold through the medium frequency heating equipment, forming a high-heat bent tube. When the high-heat bent tube falls, it lands on the receiving part. The receiving part is compressed by the spring at the bottom, causing the receiving part to rotate slowly along the rotating rod, thus buffering the workpiece on the receiving part and conveying it to the roller conveyor belt. The roller conveyor belt transports the workpiece to the next processing stage, effectively avoiding the high-heat bent tubes from bumping and piling up during unloading, ensuring the integrity of the bent tube wall, ensuring processing quality, and facilitating the manual transfer of individual continuously transported high-heat bent tubes, resulting in high safety.

[0015] With this elbow hot pushing machine, the operator observes from one side of the equipment. When workpieces stick together, the cylinder is activated. The cylinder drives the push rod forward through the output end. The push rod frames the outer wall of the workpiece through a C-shaped structure. Through radial movement, the workpiece is detached from the end of the mold and the end of the next workpiece, thereby accelerating the bending and unloading process and ensuring processing efficiency.

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

[0023] Example 1

[0024] This embodiment provides a servo hydraulic elbow hot pusher, such as Figure 1-4 As shown, the elbow hot pusher includes a processing table 1, a hydraulic hot push assembly 2 fixedly installed on the processing table 1, a medium-frequency heating device 3 fixedly installed on the processing table 1 and adapted to the hydraulic hot push assembly 2, a workpiece 4 sleeved on the hydraulic hot push assembly 2 and passing through the medium-frequency heating device 3, a roller conveyor belt 5 set below the processing table 1, and a buffer unloading mechanism 6 set on the processing table 1.

[0025] The buffer feeding mechanism 6 includes a receiving part 61 located on the processing table 1 below the medium frequency heating device 3. One end of the receiving part 61 is inserted into a rotating rod 62 that is rotatably connected to the processing table 1. A spring 63 is provided at the bottom of the receiving part 61 at a position different from the rotating rod 62. The end of the receiving part 61 away from the rotating rod 62 is located above the roller conveyor belt 5.

[0026] In use, workpieces 4 are placed one by one on the mold of the hydraulic hot push assembly 2. The hydraulic hot push assembly 2 pushes the workpieces 4 on the mold through the medium frequency heating equipment 3, and the workpieces 4 are hot-pushed to form a high-heat bend. When the high-heat bend falls, it falls onto the receiving part 61. The receiving part 61 is compressed by the spring 63 at the bottom, so that the receiving part 61 rotates slowly along the rotating rod 62, thereby buffering the workpieces 4 on the receiving part 61 and conveying the workpieces 4 to the roller conveyor belt 5. The roller conveyor belt 5 transports the workpieces 4 to the next processing stage, effectively avoiding the high-heat bends from bumping and accumulating during unloading, ensuring the integrity of the bend wall, ensuring processing quality, and facilitating the manual transfer of individual continuously transported high-heat bends, with high safety.

[0027] Specifically, the receiving part 61 has an inverted V-shaped design, and a through receiving groove 64 is provided on the receiving part 61.

[0028] In use, the joint of the receiving groove 64 of the receiving part 61 is designed with an arc chamfer. After the workpiece 4 is processed, it falls into the receiving groove 64 on the receiving part 61, which limits the workpiece 4 so that the workpiece 4 can fall stably on the roller conveyor belt 5 after pressing down on the receiving part 61, thus completing the stable feeding.

[0029] More specifically, a first connecting block 65 is fixedly installed on the processing table 1, and a second connecting block 66 is fixedly installed on the receiving part 61 near the end of the rotating rod 62. The rotating rod 62 passes through the first connecting block 65 and the second connecting block 66, and the first connecting block 65 and the second connecting block 66 are rotatably connected to the rotating rod 62.

[0030] In use, align the second connecting block 66 with the first connecting block 65 so that the second connecting block 66 and the first connecting block 65 overlap, and then insert the rotating rod 62 through the second connecting block 66 and the first connecting block 65 to complete the detachable connection between the receiving part 61 and the processing table 1, so as to facilitate the disassembly and assembly of the receiving part 61 for inspection and maintenance.

[0031] Furthermore, a support plate 67 is fixedly installed on the roller conveyor belt 5, and a first receiving block 68 adapted to the spring 63 is fixedly installed on the support plate 67. A second receiving block 69 adapted to the spring 63 is fixedly installed at the bottom of the receiving part 61. The two ends of the spring 63 are respectively sleeved on the first receiving block 68 and the second receiving block 69, and the two ends of the spring 63 are welded to the first receiving block 68 and the second receiving block 69.

[0032] In use, the support plate 67 is fixed on the roller conveyor belt 5, the spring 63 is squeezed to contract it, and then the two ends of the spring 63 are aligned with the first receiving block 68 and the second receiving block 69. The spring 63 is released and rebounds to lock the first receiving block 68 and the second receiving block 69. Spot welding is then performed to complete the installation of the spring 63, which can stably support the receiving part 61 and facilitate maintenance.

[0033] Example 2

[0034] Unlike Embodiment 1, the current elbow hot pusher mostly falls by its own gravity after being pushed into shape. However, the high temperature elbow is prone to sticking to the end of the inner wall of the mold or the next workpiece 4, which requires manual prying or knocking to remove, affecting processing efficiency. Therefore, the elbow hot pusher also includes an auxiliary separation mechanism 7 set on the processing table 1 to quickly detach the stuck workpiece 4 and let it fall onto the receiving part 61.

[0035] In use, the auxiliary separation mechanism 7 assists in pushing the sticky workpiece 4 during the unloading process, so that the high-temperature elbow can quickly detach from the mold and fall onto the receiving part 61 to complete the unloading, thus avoiding affecting subsequent processing and improving processing efficiency.

[0036] Specifically, the auxiliary separation mechanism 7 includes a cylinder 71 fixedly installed on the processing table 1. The output end of the cylinder 71 is aligned with the axial extension direction of the hydraulic hot push assembly 2. A push rod 72 with a C-shaped design that is adapted to the outer wall surface of the workpiece 4 is fixedly installed at the output end of the cylinder 71.

[0037] During use, the operator observes from one side of the equipment. When workpiece 4 sticks, the cylinder 71 is activated. The cylinder 71 drives the push rod 72 forward through the output end. The push rod 72 frames the outer wall of workpiece 4 through the C-shaped structure. Through radial movement, workpiece 4 is detached from the mold end and the end of the next workpiece 4, thereby accelerating the bending and unloading of the tube and ensuring processing efficiency.

[0038] Understandably, the C-shaped push rod 72 design allows the push rod 72 to push the workpiece 4 more stably into the receiving part 61, preventing the workpiece 4 from deviating and making the feeding more stable.

[0039] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
