Description

Technical Field

[0001] This utility model belongs to the field of extrusion press technology. Specifically, this utility model relates to the circuit structure of the interrupt saw follow-up mechanism of an extrusion press. Background Technology

[0002] The follow-up mechanism of the interrupt saw in an aluminum profile extrusion press typically uses a retractable cable tray with built-in wires, laid at the bottom of the interrupt saw. The cable tray dynamically moves as the interrupt saw moves. The cable tray is made of flame-retardant nylon material and has a hollow center.

[0003] A patent application (patent number 202322695885.9, published on April 23, 2024) discloses a discharge interruption saw for an extruder with a linkage protection device. The saw includes a worktable and an interruption saw mounted on the worktable. A protection mechanism is provided on the interruption saw, comprising a protective cover, a limiting groove, a limiting block, and a linkage component. The limiting block and limiting groove are located on one side of the protective cover, and the limiting block and the inner cavity of the limiting groove are slidably interlocked. The linkage component is located on one side of the limiting block. This invention utilizes the coordinated arrangement of the protective component and the interruption saw to prevent the cutting part of the interruption saw from being exposed and posing a danger to the operator. The protective cover protects the cutting area while the saw blade is in use, effectively preventing accidents caused by accidental contact with the saw blade and ensuring operator safety during operation. This enhances the safety and practicality of the interruption saw.

[0004] During the sawing process, the interrupt saw will produce a large amount of high-temperature aluminum shavings. Aluminum shavings are a good conductor of electricity and often enter the cable tray. They are not easy to clean and after a period of time, they often cause damage to the insulation layer of the wires in the tray, resulting in poor insulation and electrical circuit failure. Utility Model Content

[0005] The present invention aims to provide a circuit structure for a follower mechanism of an extruder interrupt saw that can effectively protect cables.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a circuit structure for a follow-up mechanism of an extruder interrupt saw, including a frame and a flexible cable connected to the interrupt saw. The frame is provided with a track for fixing the flexible cable. The flexible cable is suspended above the extruder in a wave-like shape. The track is a U-shaped aluminum alloy track. A buckle for fixing the flexible cable is slidably connected inside the track. A pulley is provided on the side of the buckle inside the track. The flexible cable is a double-layer composite structure cable. The inner side of the flexible cable is a copper conductor, and the outer side of the flexible cable is a protective layer that wraps the copper conductor. The protective layer is divided into an inner polyurethane insulation layer and an outer polyether-type polyurethane sheath.

[0007] The bottom of the buckle is provided with an arc-shaped split elastic piece for engaging the flexible cable.

[0008] The technical advantages of this utility model are as follows: the use of upper-mounted installation can greatly reduce the damage of high-temperature aluminum chips to the insulation layer during sawing; the simple track structure makes it less likely for aluminum chips and oil stains to accumulate, and does not affect the normal use of the interrupt saw. Attached Figure Description

[0009] This manual includes the following figures, which illustrate the following: Figure 1 This is a schematic diagram of the circuit structure of the extruder interrupt saw follower mechanism of the present invention; Figure 2 for Figure 1 A schematic diagram of the latching structure of the circuit of the interrupted saw follower mechanism of an extruder.

[0010] The markings in the diagram are: 1. Frame; 2. Flexible cable; 3. Track; 4. Clip; 5. Pulley; 6. Elastic sheet; 7. Copper conductor; 8. Insulation layer; 9. Sheath. Detailed Implementation

[0011] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0012] Please see Figure 1-2 A circuit structure for a follower mechanism of an extruder interrupt saw includes a frame 1 and a flexible cable 2 connected to the interrupt saw. The frame 1 has a track 3 for fixing the flexible cable 2, which is suspended above the extruder in a wavy pattern. This upper-mounted, suspended arrangement of the flexible cable 2 creates a large gap between the cable 2 and the cutting point of the interrupt saw. During cutting, aluminum chips are less likely to fly high, and their temperature drops significantly during their journey to higher ground, greatly reducing the damage to the insulation layer 8 caused by the high-temperature aluminum chips during sawing. Furthermore, because the flexible cable 2... The outer side is equipped with a sheath 9, which can effectively reduce the damage of high-temperature aluminum shavings to the insulation layer 8. The simple track 3 structure does not easily accumulate aluminum shavings and oil stains, and does not affect the normal use of the interrupt saw. Since the flexible cable 2 is set in a wavy shape, there are multiple connection points between the flexible cable 2 and the track 3. In this way, when the interrupt saw moves, the flexible cable 2 will be folded up and will not affect normal use. As will be seen later, the flexible cable 2 is connected to the track 3 through a sliding buckle 4. In this way, when the interrupt saw moves, the flexible cable 2 will not affect the normal movement and cutting of the interrupt saw.

[0013] Track 3 is a concave aluminum alloy track; it has a simple structure, and aluminum alloy is inexpensive and has good load-bearing capacity, which is conducive to long-term use.

[0014] The track 3 is slidably connected with a buckle 4 that fixes the flexible cable 2; the buckle 4 fixes the flexible cable 2, and the buckle 4 can slide along the track 3 to prevent the fixed connection from affecting the normal use of the interrupt saw.

[0015] The side of the buckle 4 is provided with a pulley 5 located in the track 3; this facilitates the movement of the buckle 4.

[0016] The flexible cable 2 is a double-layer composite structure cable. The inner side of the flexible cable 2 is a copper conductor 7, and the outer side of the flexible cable 2 is a protective layer that wraps the copper conductor 7. The outer protective layer protects the inner copper conductor 7, which can greatly reduce the damage to the insulation layer 8 caused by high-temperature aluminum chips during sawing.

[0017] The protective layer consists of an inner polyurethane insulation layer 8 and an outer polyether-type polyurethane sheath 9. The outer sheath 9 protects the inner insulation layer 8 and the copper conductor 7. The polyether-type polyurethane has good low-temperature flexibility, is easy to bend and stretch, can withstand repeated bending and stretching for a long time, and has a long service life.

[0018] The bottom of the buckle 4 is provided with an arc-shaped split elastic piece 6 for attaching the flexible cable 2; making it easy to insert the flexible cable 2.

[0019] Working principle: By completely abandoning the drag chain trough and the method of laying from below, an upper concave aluminum alloy track 3 and a flexible cable 2 are used. The concave aluminum alloy track 3 is 3 meters long and is fixed to the equipment frame 1 with M6 bolts. The flexible cable 2 is fixed in sections by self-locking buckles 4. At the same time, the buckles 4 are embedded in the concave track 3 and can move freely by rollers. The flexible cable 2 adopts a double-layer composite structure. The inner layer is a 9-strand copper conductor 7, and the outer layer is covered with a polyurethane insulation layer 8 and a polyether-type polyurethane sheath 9. It can meet the harsh environment requirements of the extrusion workshop with oil, easy wear, and high temperature. The upper laying method can greatly reduce the damage of high temperature aluminum chips to the insulation layer 8 during sawing. The simple track 3 structure does not easily accumulate aluminum chips and oil stains.

[0020] The technical advantages of this utility model are as follows: the use of upper-mounted installation can greatly reduce the damage of high-temperature aluminum chips to the insulation layer 8 during sawing; the simple track structure 3 does not easily accumulate aluminum chips and oil stains, and does not affect the normal use of the interrupt saw.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
