Description

Technical Field

[0001] This utility model belongs to the field of disassembly and assembly tooling technology, specifically, it relates to a tooling for disassembling and assembling screws in an extruder flow channel. Background Technology

[0002] In industrial production, extruders are core equipment for processing polymer materials such as plastics, rubber, and synthetic fibers. The stable operation of their flow channel system directly affects product quality and production efficiency. As a key channel for material melting and conveying, the flow channel is in constant contact with high-temperature molten materials, and its inner wall temperature is often maintained at a high level (reaching several hundred degrees Celsius in some scenarios). In order to adapt to the material flow characteristics, the interior of the flow channel is often designed as a long, narrow, curved, or complex corner structure, resulting in extremely limited internal operating space, which poses a significant challenge to the screw disassembly and assembly operations during flow channel maintenance.

[0003] Currently, the industry commonly uses conventional hex wrenches or socket wrenches to disassemble and assemble flow channel screws. However, these tools have many insurmountable drawbacks when dealing with the special environment of flow channels:

[0004] Firstly, due to the high temperature of the flow channel wall and the limited length of conventional tools, operators need to be close to the flow channel opening to operate. Their arms, hands and other parts are very likely to come into contact with the high temperature pipe wall, causing safety accidents such as burns and bruises. The risk of operation in a high temperature environment is even more prominent, especially in emergency maintenance after continuous production.

[0005] Secondly, conventional wrenches need to be strictly vertically aligned with the screw head to apply force effectively. However, the narrow space inside the flow channel limits the tool's adjustment angle. Operators often need to repeatedly try and adjust the tool's position, which is not only time-consuming and laborious, but may also cause the tool to slip on the screw head due to alignment deviation, further prolonging the disassembly and assembly time and affecting the normal production cycle of the equipment.

[0006] Third, due to limitations in operating space and tools, screws often lack sufficient tightening torque due to uneven force application or improper installation. After long-term use, they are prone to loosening, leading to a decrease in the sealing performance of the flow channel, causing problems such as leakage of molten material and unstable pressure. This not only affects the molding accuracy and physical properties of the product, but may also cause internal contamination of the equipment due to material leakage, increasing the equipment failure rate and maintenance costs, and even posing a potential threat to production safety.

[0007] Furthermore, the fixed structure of existing tools exacerbates the difficulty of operation—the handle and working end are mostly rigidly connected, making it impossible to adjust the angle according to the internal space of the flow channel. When encountering flow channel corners or obstacles, the tool is prone to jamming, further reducing operational flexibility and reliability. These problems have long plagued extruder maintenance, necessitating a specialized disassembly and assembly tool that can adapt to the confined, high-temperature environment of the flow channel, improve operational safety and efficiency, and ensure installation quality. Utility Model Content

[0008] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a tooling for disassembling and assembling extruder flow channel screws.

[0009] According to the present invention, a tooling for disassembling and assembling an extruder flow channel screw includes a ball-head hexagonal socket and an H-shaped sleeve. The ball-head hexagonal socket is fixedly connected to the H-shaped sleeve. The side wall of the ball-head hexagonal socket is regular hexagonal. A protrusion is provided at the end of the ball-head hexagonal socket away from the H-shaped sleeve. A transition inclined wall is provided between the protrusion and the ball-head hexagonal socket. An H-shaped sleeve opening is provided at the end of the H-shaped sleeve away from the ball-head hexagonal socket.

[0010] In a preferred embodiment: the sum of the lengths of the ball head hexagonal socket and the H-shaped sleeve is in the range of -cm.

[0011] In a preferred embodiment: the protrusion is a regular hexagon, and the size of the protrusion is smaller than the sidewall size of the inner hexagon of the ball head.

[0012] In a preferred embodiment: the transition bevel is used to guide the ball head hexagonal socket and the screw head to form a stable engagement at a non-perpendicular angle.

[0013] In a preferred embodiment: the H-type sleeve opening is a square interface with a specification of / inch or / inch.

[0014] In a preferred embodiment: the H-shaped socket is used to engage with a ratchet wrench with a ratchet wrench head.

[0015] In a preferred embodiment: the ratchet wrench head is provided with a groove, and a rotating shaft is rotatably mounted in the groove, the rotating shaft being connected to one end of the handle.

[0016] In a preferred embodiment: the sidewall of the ball head hexagonal socket is used to mate with the screw head.

[0017] In a preferred embodiment: the protrusion is used to align the screw head into the narrow gap of the flow channel.

[0018] In a preferred embodiment, the handle can be rotated within the groove via a pivot to adjust the angle to adapt to the complex operating space within the flow channel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This utility model achieves non-perpendicular angle engagement with the screw head by means of the protrusion at the end of the ball head hexagonal end and the transition slope wall. It can be operated without strict vertical alignment, effectively adapting to the narrow space of the extruder flow channel and solving the problem of difficult and time-consuming alignment of conventional tools in narrow spaces.

[0021] 2. This utility model extends the operating distance by connecting the H-shaped socket with the ratchet wrench head, avoiding close contact between the operator and the high-temperature flow channel wall, reducing the safety risks of burns and bruises, and solving the operational safety hazards caused by the insufficient length of existing tools.

[0022] 3. This utility model uses the groove on the ratchet wrench head to cooperate with the pivot on the handle, so that the handle can be rotated flexibly to adjust the angle, which can adapt to complex spatial environments such as corners inside the flow channel, ensuring smooth force application, and solving the problem that conventional tools are limited in operation in narrow spaces due to fixed angles.

[0032] like Figure 1-4As shown, this utility model discloses a tooling for disassembling and assembling screws in an extruder flow channel, including a ball-head hexagonal socket head cap 1 and an H-shaped sleeve 2. The ball-head hexagonal socket head cap 1 and the H-shaped sleeve 2 are fixedly connected. The sum of the lengths of the ball-head hexagonal socket head cap 1 and the H-shaped sleeve 2 is in the range of 5-7 cm to accommodate the narrow space inside the flow channel. The sidewall of the ball-head hexagonal socket head cap 1 is regular hexagonal for mating with the screw head. A protrusion 3 is provided at the end of the ball-head hexagonal socket head cap 1 away from the H-shaped sleeve 2. The protrusion 3 is... The screw head is hexagonal, and the size of the protrusion 3 is smaller than the side wall of the ball head hexagon 1. A transitional inclined wall 9 is provided between the protrusion 3 and the ball head hexagon 1 to enable multi-angle insertion of the screw head and support non-vertical operation. The end of the H-type socket 2 away from the ball head hexagon 1 is provided with an H-type socket opening 4. The H-type socket opening 4 is a 1 / 4-inch or 3 / 8-inch square interface. The H-type socket opening 4 is used in conjunction with a ratchet wrench with a ratchet wrench head 5 to extend the operating distance and avoid the risk of high temperature.

[0033] like Figure 5 As shown, the ratchet wrench head 5 is provided with a groove 7 and a handle 6. One end of the handle 6 is provided with a rotating shaft 8, which is rotatably installed in the groove 7, so that the handle 6 can rotate to adapt to the complex operating space in the flow channel.

[0034] Working principle

[0035] When this utility model is used, the protrusion 3 of the ball head internal hexagon 1 is a small regular hexagon, which can penetrate into the narrow gap of the flow channel to align with the small screw head and is compatible with standard size internal hexagon screws. During the alignment process, the protrusion 3 or the side wall contacts the screw head, and the transition inclined wall 9 between the two is optimized by tilting angle, which can guide the formation of a stable fit in a non-vertical state (such as when there is a certain angle), get rid of the limitation of vertical alignment of conventional tools, and is suitable for narrow space of the flow channel.

[0036] Next, connect the H-shaped socket 4 of the H-shaped socket 2 to the ratchet wrench head 5. The two work together to transmit force efficiently. Since the total length of the ball head hexagon 1 and the H-shaped socket 2 is 5-7cm, it is suitable for the flow channel depth. With the ratchet wrench, the operating distance can be extended, avoiding close contact with the high temperature flow channel wall.

[0037] If space is limited, the groove 7 of the ratchet wrench head 5 provides rotation space for the pivot 8 of the handle 6, which can flexibly adjust the handle angle to make the application of force smoother. With the rotation of the handle 6, the screw can be tightened or loosened easily, greatly improving the efficiency and safety of operation.
