Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and in particular to a cable extrusion device. Background Technology

[0002] In the field of wire and cable manufacturing, the insulation and sheath of cables are crucial components that protect the internal conductors, extend cable lifespan, and ensure cable safety. The core of cable extrusion molding equipment lies in uniformly extruding plastic material onto the cable core to form a stable insulation and sheath. Traditional methods often rely on manual operation and simple mechanical equipment, resulting in inconsistent product quality. Traditional cable insulation and sheath production methods suffer from low production efficiency and unstable product quality, making it difficult to meet the demands of modern industry for high-efficiency, high-quality cable products.

[0003] Existing cable extrusion equipment requires adjustments to accommodate cables of different diameters during the extrusion process. Most existing cable extrusion equipment is of fixed specifications, requiring machine or extrusion ring replacements to accommodate different cable diameters. Furthermore, the extrusion rings in existing cable extrusion equipment are mostly installed using bolts or welding, which greatly reduces the applicability of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a cable extrusion device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable extrusion device, comprising a base plate for installing the cable extrusion device and an extrusion ring for cable extrusion, wherein the top surface of the base plate is symmetrically fixedly mounted with mounting frames, and hydraulic cylinders are fixedly mounted on the two mounting frames respectively, and U-shaped frames are fixedly mounted on the telescopic ends of the hydraulic cylinders, and traction rollers are rotatably mounted on the inner walls of the U-shaped frames and the mounting frames.

[0006] An extrusion cylinder is fixedly installed on the top surface of the base plate. The extrusion ring is slidably installed inside the extrusion cylinder, and a feed pipe is connected to the top surface of the extrusion ring. An annular opening is provided on the inner wall of the extrusion ring.

[0007] Vertical plates are symmetrically fixedly installed on the top surface of the base plate. Slide grooves are opened on opposite sides of the two vertical plates. Sliding blocks are symmetrically slidably installed on the inner walls of the slide grooves. A shaping roller is rotatably installed between two corresponding sliding blocks.

[0008] A cooling and shaping cylinder is fixedly installed on the top surface of the base plate, and an inlet pipe and an outlet pipe are respectively connected to the top surface of the cooling and shaping cylinder.

[0009] Preferably, push springs are fixedly installed on both the upper and lower sides of the inner wall of the groove opened on the side wall of the vertical plate, and the ends of the two push springs are respectively fixedly installed on the side walls of the two sliders.

[0010] Preferably, the inner wall of the slide is longitudinally fixed with a limit rod, and the side wall of the slider is longitudinally provided with a limit hole.

[0011] Preferably, the limiting rods slide through the limiting holes opened on the side wall of the slider.

[0012] Preferably, the inner wall of the slide groove has two symmetrically formed limiting grooves, and the side wall of the slider has two limiting blocks fixedly installed.

[0013] Preferably, the two limiting blocks fixedly installed on the side wall of the slider are slidably installed inside the two limiting grooves opened on the inner wall of the slide groove.

[0014] Preferably, the extrusion cylinder has multiple mounting grooves with different inner diameters inside, and extrusion rings of different diameters are slidably engaged into the mounting grooves of different inner diameters.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] This cable extrusion device, thanks to the arrangement of two vertical plates, chutes, sliders, and extrusion rollers, can effectively shape the extruded cable passing between the two molding rollers by pushing multiple sliders and extruding the two molding rollers together through multiple push springs.

Detailed Implementation

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 4 The main structure of the cable extrusion device shown is a base plate 1 for cable extrusion device installation and an extrusion ring 7 for cable extrusion. The top surface of the base plate 1 is symmetrically fixed with an installation frame 2, which is U-shaped.

[0031] Hydraulic cylinders 3 are fixedly installed on the two mounting frames 2 respectively, and U-shaped frames 4 are fixedly installed on the telescopic ends of the hydraulic cylinders 3. Traction rollers 5 are rotatably installed on both the U-shaped frames 4 and the inner wall of the mounting frames 2. Thanks to the arrangement of the two mounting frames 2, hydraulic cylinders 3, U-shaped frames 4 and traction rollers 5, the distance between the two traction rollers 5 can be adjusted by the hydraulic cylinders 3, so as to realize the traction and transportation of cables of different diameters.

[0032] An extrusion cylinder 6 is fixedly installed on the top surface of the base plate 1. An extrusion ring 7 is slidably installed inside the extrusion cylinder 6, and a feed pipe 8 is connected to the top surface of the extrusion ring 7. An annular opening is provided on the inner wall of the extrusion ring 7. Thanks to the setting of different inner diameters of the extrusion ring 7, it is possible to effectively extrude cables of different specifications.

[0033] Vertical plates 10 are symmetrically fixedly installed on the top surface of the base plate 1. Slide grooves 11 are opened on opposite sides of the two vertical plates 10. Slide blocks 12 are symmetrically slidably installed on the inner wall of the slide grooves 11. A molding roller 13 is rotatably installed between the two corresponding slide blocks 12. Thanks to the arrangement of the two vertical plates 10, slide grooves 11, slide blocks 12 and molding rollers 13, multiple push springs 16 can effectively push multiple slide blocks 12 and two molding rollers 13 to squeeze each other, thereby shaping the extruded cable passing between the two molding rollers 13. At the same time, because there is a certain sliding stroke between the slide block 12 and the push spring 16, the two molding rollers 13 can shape cables of different specifications.

[0034] A cooling and shaping cylinder 14 is fixedly installed on the top surface of the base plate 1. An inlet pipe and an outlet pipe 15 are respectively connected to the top surface of the cooling and shaping cylinder 14. The coolant circulates inside the cooling and shaping cylinder 14 through the inlet pipe and the outlet pipe 15, thereby further improving the cooling and shaping of the cable after shaping by the cooling and shaping cylinder 14.

[0035] Push springs 16 are fixedly installed on the upper and lower sides of the inner wall of the groove 11 opened on the side wall of the vertical plate 10. The ends of the two push springs 16 are fixedly installed on the side walls of the two sliders 12 respectively. Thanks to the setting of the push springs 16, cables of different diameters can be effectively squeezed and shaped, thereby further improving the applicability of the device.

[0036] Limiting rods 17 are fixedly installed longitudinally on the inner wall of the slide 11, and limiting holes are opened longitudinally on the side wall of the slider 12. The limiting rods 17 slide through the limiting holes opened on the side wall of the slider 12. Thanks to the setting of the limiting rods 17, multiple sliders 12 can be effectively limited, and the applicability of the two shaping rollers 13 is further improved, and the effect of the two shaping rollers 13 on cable shaping is further improved.

[0037] Two limiting grooves are symmetrically opened on the inner wall of the slide groove 11. Two limiting blocks 18 are fixedly installed on the side wall of the slider 12. The two limiting blocks 18 fixedly installed on the side wall of the slider 12 are slidably installed inside the two limiting grooves opened on the inner wall of the slide groove 11. Thanks to the setting of the limiting blocks 18, the sliding direction of the slider 12 can be effectively limited, and the stability of the two shaping rollers 13 when sliding is further improved.

[0038] The extrusion cylinder 6 has multiple mounting grooves 9 with different inner diameters inside, and extrusion rings 7 of different diameters slide and engage with the mounting grooves 9 of different inner diameters. Thanks to the multiple mounting grooves 9 of different inner diameters, extrusion rings 7 of different diameters can be effectively installed, thereby enabling the extrusion of cables of different specifications and further improving the applicability of the device.

[0039] Working principle

[0040] In use, this cable extrusion device first passes the cable through one set of traction rollers 5, then through the extrusion cylinder 6 and the extrusion ring 7 inside the extrusion cylinder 6, then through two forming rollers 13, and then slides the shaped cable through the cooling and shaping cylinder 14. Finally, the shaped cable passes between another set of traction rollers 5. When it is necessary to change the extrusion ring 7 with a different inner diameter according to different cable diameters, the extrusion ring 7 is removed from the inside of the extrusion cylinder 6, and then a brand new extrusion ring 7 is taken out and placed inside the mounting groove 9 opened in the extrusion cylinder 6 that matches the diameter of the extrusion ring 7. Then the cable is passed through the extrusion cylinder 6 and the extrusion ring 7. This can effectively extrude cables of different diameters. At the same time, the push spring 16 can squeeze the two forming rollers 13 to keep them in close contact with the outside of the extruded cable, thus realizing the extrusion and shaping of cables of different diameters.
