Description

Technical Field

[0001] The present invention relates to the technical field of pipe expanding devices, and in particular to an end expanding device for producing cable protection pipes for new energy vehicles. Background Art

[0002] End expanding equipment is a device used to expand the ends of workpieces such as pipes and bars. Through a specific mechanical structure and working principle, the diameter of the end of the workpiece is evenly expanded according to the set requirements to meet different industrial application needs. The processing methods of end expanding equipment include thermal expanding processing methods. Thermal expanding equipment mainly uses heat conduction, induction heating and other methods to make the end of the pipe or workpiece reach a certain temperature, reduce the hardness and yield strength of the material, and then apply the expanding mold to the heated part through mechanical force to make the material undergo plastic deformation in a softened state, thereby achieving the purpose of expanding.

[0003] However, when the cable protection tube is processed by heat expansion, there are fine particles such as dust and debris on the inner wall and surface of the cable protection tube port, which can easily affect the expansion effect of the cable protection tube port when the cable protection tube port is heated and expanded. At the same time, after the cable protection tube port is heated and expanded, when the cable protection tube port is separated from the expansion mold, the expansion part of the cable protection tube and the expansion mold lose support, which may cause the port part of the cable protection tube to be deformed after expansion, resulting in poor expansion effect of the cable protection tube port. Therefore, the present application provides an end expansion device for the production of new energy vehicle cable protection tubes to meet the needs. Summary of the invention

[0027] like Figures 1 to 10 As shown, an embodiment of the present invention provides an end expanding device for producing a cable protection tube for a new energy vehicle, comprising a mounting base 1, a slide groove 2 is installed on one side of the top of the mounting base 1, a sliding base 3 is arranged on the top of the slide groove 2, a fixing fixture 4 is installed on the inner side of the sliding base 3, a hydraulic rod 40 is connected to one end of the fixing fixture 4, a double rack 5 is installed on the bottom end of the fixing fixture 4, and the double rack 5 is formed by fixedly splicing two groups of racks, a heating device 6 is installed on the top of the mounting base 1, a expanding mold 7 is installed on the top of the mounting base 1, a cleaning component 8 is installed on the top of the mounting base 1, and the cleaning component 8 is used to clean the outer surface of the end of the cable protection tube, a scraping component 9 is installed on one side of the top of the mounting base 1, and the scraping component 9 is used to scrape the inner wall of the end of the cable protection tube, and a support component 10 is installed on the scraping component 9. The support component 10 is used to provide auxiliary support after the end of the cable protection tube is expanded, and the scraping component 9 is located on one side of the cleaning component 8. The support component 10 is located on one side of the cleaning component 8.

[0028] By setting a cleaning component 8, the port of the cable protection tube passing through the inner side of the sponge ring 87 is rotated and cleaned, and the dust and debris on the surface of the cable protection tube port are centrally cleaned to avoid the dust and debris on the surface of the cable protection tube port from affecting the subsequent heating and softening treatment, thereby improving the heating effect on the cable protection tube port, thereby improving the expansion effect of the subsequent expansion mold 7 on the cable protection tube port. By setting a scraping component 9, the rubber roller 94 and the scraping column 95 can be closely attached to the inner wall of the cable protection tube, and at the same time cooperate with the fixing fixture 4 to drive the cable protection tube to rotate, and the rubber roller 94 is used to scrape the inner wall of the cable protection tube. The wall is cleaned twice, and the chemical properties of silicone rubber, such as high heat resistance and low surface energy, are utilized to avoid the rubber roller 94 and the scraping column 95 from sticking to the heated inner wall of the cable protection tube when cleaning and scraping the inner wall of the cable protection tube after the expansion process. By setting a support component 10 and utilizing the ejection and retraction effects of multiple groups of support plates 109, auxiliary support is achieved for the inner wall of the expanded port of the cable protection tube. By supporting the inner wall of the expanded port of the cable protection tube, deformation of the expanded port of the cable protection tube when demolding from the expansion mold 7 is avoided, thereby further improving the yield rate of the expanded cable protection tube.

[0029] like Figure 3 to Figure 4 As shown, the cleaning assembly 8 includes a mounting ring 81, which is mounted on the top of the mounting base 1, a rotating ring 82 is mounted on one side of the mounting ring 81, a gear ring 83 is mounted on the outer side of one end of the rotating ring 82, a bevel gear 84 is meshed with the bottom end of the gear ring 83, a rotating rod 85 is mounted on the bottom end of the bevel gear 84, the rotating rod 85 is mounted on the top surface of the mounting base 1, a flat gear 86 is mounted on the bottom end of the rotating rod 85, the flat gear 86 is meshed with the double rack 5, and a sponge ring 87 is mounted on the inner side of one end of the rotating ring 82.

[0030] The operator clamps and fixes the cable protection tube by the fixing fixture 4, and then starts the hydraulic rod 40. After the hydraulic rod 40 is started, it pushes the sliding base 3 and the fixing fixture 4 to slide horizontally along the slide groove 2. When the sliding base 3 slides, the fixing fixture 4 and the cable protection tube slide synchronously. When the fixing fixture 4 slides, it drives the cable protection tube to approach and contact the heating device 6. During this process, the fixing fixture 4 drives the double rack 5 at the bottom to slide synchronously. Under the sliding action of the double rack 5, the double rack 5 first contacts and meshes with the flat gear 86 to rotate. When the flat gear 86 rotates, it drives the bevel gear 84 to rotate synchronously through the rotating rod 85. When the bevel gear 84 rotates, it meshes with the meshing ring 83 to rotate. Under the rotation action of the bevel gear 84, the meshing ring 83 rotates synchronously. When the meshing ring 83 rotates, it drives the rotating ring 82 to rotate on one side of the mounting ring 81. When the rotating ring 82 rotates, it drives the sponge ring 87 on the inside to rotate synchronously. When the sponge ring 87 rotates, it contacts the surface of the cable protection tube. At the same time, the sliding base 3 drives the fixing fixture 4 and the cable protection tube to slide synchronously, and the surface of the cable protection tube port passing through the inner wall of the sponge ring 87 is cleaned.

[0031] By setting the linkage between the rotating ring 82, the meshing ring 83 and the bevel gear 84, the fixing clamp 4 is used to drive the cable protection tube to slide back and forth to reset, so as to realize the rotation effect of the rotating ring 82. By using the rotating ring 82 to drive the sponge ring 87 to rotate synchronously, the port position of the cable protection tube passing through the inner side of the sponge ring 87 is rotated and cleaned, thereby improving the heating effect on the port of the cable protection tube, thereby improving the expanding effect of the subsequent expanding mold 7 on the port of the cable protection tube.

[0032] like Figures 5 to 7 As shown, the scraping assembly 9 includes a mounting bracket 91, which is mounted on one side of the top of the mounting base 1, an elastic telescopic rod 92 is elastically mounted on the top of the mounting bracket 91, a mounting plate 93 is mounted on the top of the elastic telescopic rod 92, the number of the elastic telescopic rods 92 and the mounting plate 93 are set to multiple groups, and the multiple groups of elastic telescopic rods 92 and mounting plates 93 are arranged in an equiangular circular array on the top of the mounting bracket 91, a rubber roller 94 is installed on the inner wall of the mounting plate 93, the cross-section of one end of the rubber roller 94 is designed to be a trapezoidal structure, the material of the rubber roller 94 is set to be silicone rubber material, and a scraping column 95 is installed on the surface of the rubber roller 94, the number of the scraping column 95 is set to multiple groups, and the multiple groups of scraping column 95 are arranged in an equiangular circular array on the surface of the rubber roller 94.

[0033] Subsequently, the sliding base 3 continues to slide while driving the fixing clamp 4 and the cable protection tube to continue to slide synchronously, so that the surface of the cable protection tube reaches below the inner wall of the heating device 6, and the fixing clamp 4 rotates to drive the cable protection tube and heat and soften the surface of the cable protection tube port through the heating device 6.

[0034] Subsequently, the sliding base 3 drives the fixing clamp 4 and the softened cable protection tube to continue to slide and contact the expanding die 7. At the same time, the fixing clamp 4 rotates to drive the cable protection tube and squeeze the expanding die 7. Through the rotation effect of the cable protection tube and the squeezing force between the expanding die 7, the port part of the cable protection tube is expanded.

[0035] When the port portion of the cable protection tube approaches and contacts the expanding mold 7, the inner wall of the port portion of the cable protection tube first contacts the inclined surface of one end of the rubber roller 94, and at the same time, under the continuous sliding action of the fixing clamp 4 and the cable protection tube, the inner wall of the port of the cable protection tube slides against the surface of the rubber roller 94. In this process, under the action of the contact force between the inner wall of the port of the cable protection tube and the rubber roller 94, the inner wall of the port of the cable protection tube squeezes and pushes the rubber roller 94 to slide. When the rubber roller 94 slides, it drives the mounting plate 93 to slide synchronously as a whole. When the mounting plate 93 slides, it squeezes the elastic telescopic rod 92, causing the elastic telescopic rod 92 to shrink, and at the same time, the rubber roller 94 and the scraping column 95 are tightly against the inner wall of the port of the cable protection tube.

[0036] The fixing fixture 4 drives the cable protection tube to rotate, and at the same time, the inner wall of the cable protection tube rotates to contact the multiple groups of rubber rollers 94 and scraping columns 95, and the rubber rollers 94 and scraping columns 95 scrape and clean the inner wall of the cable protection tube.

[0037] By arranging the elastic cooperation of the elastic telescopic rod 92, the mounting plate 93 and the rubber roller 94, and by specially designing the inclined surface at one end of the rubber roller 94, the elastic change of the position between the cable protection tube and the rubber roller 94 is achieved, so that the rubber roller 94 and the scraping column 95 can be close to the inner wall of the cable protection tube, and the inner wall of the cable protection tube is cleaned twice.

[0038] like Figures 8 to 10As shown, the support assembly 10 includes a flat gear 101, a rotating rod 102 is installed at the bottom of the flat gear 101, and the rotating rod 102 is nested and installed at the bottom of the mounting bracket 91. The flat gear 101 is installed at the bottom of the mounting bracket 91 through the rotating rod 102. The flat gear 101 is meshed with the double rack 15. A flat gear 103 is installed at the top of the rotating rod 102. A rack 104 is meshed on one side of the flat gear 103. A push rod 105 is installed at one end of the rack 104. The push rod 105 is nested and installed in the middle of the mounting bracket 91. A positioning ring 106 is connected to one end of the push rod 105. A connecting rod 107 is connected to the edge of one end of the positioning ring 106, and a connecting rod is connected to the edge of the other end of the positioning ring 106. The second connecting rod 108, the other end of the connecting rod 107 and the connecting rod 2 108 is connected to a support plate 109, the material of the support plate 109 is set to silicone rubber material, the number of the connecting rod 107, the connecting rod 2 108 and the support plate 109 are all set to multiple groups, the multiple groups of connecting rods 107, the connecting rod 2 108 and the support plate 109 are arranged in an equiangular circular array on the surface of the positioning ring 106, a limiting rod 1010 is sleeved on one end of the support plate 109, the limiting rod 1010 is installed at one end of the mounting bracket 91, the number of the limiting rods 1010 is set to multiple groups, the multiple groups of limiting rods 1010 are arranged in an equiangular circular array at one end of the mounting bracket 91, and the multiple groups of limiting rods 1010 correspond one to one with the multiple groups of support plates 109.

[0039] At the same time, the double rack 15 slides and meshes with the flat gear 2 101. The double rack 15 slides and meshes with the flat gear 2 101. Under the sliding action of the double rack 15, the flat gear 2 101 produces a rotation effect. When the flat gear 2 101 rotates, it drives the flat gear 3 103 to rotate synchronously through the rotating rod 102. When the flat gear 3 103 rotates, it meshes with the rack 1 104. Under the rotation action of the flat gear 3 103, the rack 1 104 slides. When the rack 104 slides, it drives the push rod 105 to slide synchronously, so that the push rod 105 slides in the horizontal direction along the mounting bracket 91.

[0040] As the push rod 105 slides, it pushes the support plate 109 through the connecting rod 107 and the connecting rod 2 108. At the same time, under the limiting action of the limiting rod 1010, the support plate 109 slides in the opposite direction along the direction of the limiting rod 1010. As the support plate 109 slides in the opposite direction, it retracts to the outside of the positioning ring 106.

[0041] After the expanding die 7 expands the port of the cable protection tube, the hydraulic rod 40 is started to drive the sliding base 3 and the fixing fixture 4 to slide in the opposite direction along the horizontal direction of the slide groove 2, so that the expanding die 7 is out of contact with the inner wall of the cable protection tube port.

[0042] When the fixing clamp 4 slides in the reverse direction, it drives the double rack 15 to slide in the reverse direction. When the double rack 15 slides, it engages with the flat gear 2 101. Under the reverse sliding action of the double rack 15, the flat gear 2 101 produces a reverse rotation effect. When the flat gear 2 101 rotates in the reverse direction, it drives the flat gear 3 103 to rotate in the reverse direction synchronously through the rotating rod 102. When the flat gear 3 103 rotates in the reverse direction, it engages with the rack 1 104. Under the reverse rotation action of the flat gear 3 103, the rack 104 produces a reverse sliding effect. When the rack 104 slides in the reverse direction, it drives the push rod 105 to slide in the reverse direction synchronously, so that the push rod 105 slides in the reverse direction along the mounting bracket 91 horizontally.

[0043] When the push rod 105 slides in the opposite direction, it pulls the support plate 109 through the connecting rod 107 and the connecting rod 2 108. At the same time, under the limiting action of the limiting rod 1010, the support plate 109 slides in the direction of the limiting rod 1010. The support plate 109 slides and is pushed out from the surface of the positioning ring 106. When the support plate 109 slides and is pushed out, it approaches and contacts the inner wall of the expanded cable protection tube port, and provides auxiliary support for the inner wall of the expanded cable protection tube port, thereby achieving a supporting effect on the inner wall of the expanded cable protection tube port.

[0044] By setting the linkage cooperation between the flat gear 101, the flat gear 101 and the rack 104, the reciprocating sliding of the push rod 105 and the positioning ring 106 is realized. At the same time, through the connection effect of the connecting rod 107 and the connecting rod 2 108, the lateral force is converted into a vertical force, thereby realizing the ejection and retraction of multiple groups of support plates 109. Through the ejection and retraction effect of the multiple groups of support plates 109, auxiliary support is achieved for the inner wall of the expanded cable protection tube port.

[0045] The working principle of the technical solution provided by the present invention is as follows: The operator clamps and fixes the cable protection tube by the fixing clamp 4, and then starts the hydraulic rod 40. After the hydraulic rod 40 is started, it pushes the sliding base 3 and the fixing clamp 4 to slide horizontally along the slide groove 2. When the sliding base 3 slides, it drives the fixing clamp 4 and the cable protection tube to slide synchronously. When the fixing clamp 4 slides, it drives the cable protection tube to approach and contact the heating equipment 6.

[0046] During this process, the fixing fixture 4 drives the double rack 5 at the bottom to slide synchronously. Under the sliding action of the double rack 5, the double rack 5 first contacts and meshes with the flat gear 86 to rotate. When the flat gear 86 rotates, it drives the bevel gear 84 to rotate synchronously through the rotating rod 85. When the bevel gear 84 rotates, it meshes with the meshing ring 83 to rotate. Under the rotation action of the bevel gear 84, the meshing ring 83 rotates synchronously. When the meshing ring 83 rotates, it drives the rotating ring 82 to rotate on one side of the mounting ring 81. When the rotating ring 82 rotates, it drives the sponge ring 87 on the inside to rotate synchronously. When the sponge ring 87 rotates, it contacts the surface of the cable protection tube. At the same time, the sliding base 3 drives the fixing fixture 4 and the cable protection tube to slide synchronously, and the surface of the cable protection tube port passing through the inner wall of the sponge ring 87 is cleaned.

[0047] At the same time, the double rack 15 slides and meshes with the flat gear 2 101. The double rack 15 slides and meshes with the flat gear 2 101. Under the sliding action of the double rack 15, the flat gear 2 101 produces a rotation effect. When the flat gear 2 101 rotates, it drives the flat gear 3 103 to rotate synchronously through the rotating rod 102. When the flat gear 3 103 rotates, it meshes with the rack 1 104. Under the rotation action of the flat gear 3 103, the rack 1 104 slides. When the rack 104 slides, it drives the push rod 105 to slide synchronously, so that the push rod 105 slides in the horizontal direction along the mounting bracket 91.

[0048] As the push rod 105 slides, it pushes the support plate 109 through the connecting rod 107 and the connecting rod 2 108. At the same time, under the limiting action of the limiting rod 1010, the support plate 109 slides in the opposite direction along the direction of the limiting rod 1010. As the support plate 109 slides in the opposite direction, it retracts to the outside of the positioning ring 106.

[0049] Subsequently, the sliding base 3 continues to slide while driving the fixing clamp 4 and the cable protection tube to continue to slide synchronously, so that the surface of the cable protection tube reaches below the inner wall of the heating device 6, and the fixing clamp 4 rotates to drive the cable protection tube and heat and soften the surface of the cable protection tube port through the heating device 6.

[0050] Subsequently, the sliding base 3 drives the fixing clamp 4 and the softened cable protection tube to continue to slide and contact the expanding die 7. At the same time, the fixing clamp 4 rotates to drive the cable protection tube and squeeze the expanding die 7. Through the rotation effect of the cable protection tube and the squeezing force between the expanding die 7, the port part of the cable protection tube is expanded.

[0051] When the port portion of the cable protection tube approaches and contacts the expanding mold 7, the inner wall of the port portion of the cable protection tube first contacts the inclined surface of one end of the rubber roller 94, and at the same time, under the continuous sliding action of the fixing clamp 4 and the cable protection tube, the inner wall of the port of the cable protection tube slides against the surface of the rubber roller 94. In this process, under the action of the contact force between the inner wall of the port of the cable protection tube and the rubber roller 94, the inner wall of the port of the cable protection tube squeezes and pushes the rubber roller 94 to slide. When the rubber roller 94 slides, it drives the mounting plate 93 to slide synchronously as a whole. When the mounting plate 93 slides, it squeezes the elastic telescopic rod 92, causing the elastic telescopic rod 92 to shrink, and at the same time, the rubber roller 94 and the scraping column 95 are tightly against the inner wall of the port of the cable protection tube.

[0052] When the fixing fixture 4 drives the cable protection tube to rotate, the inner wall of the cable protection tube rotates to contact the multiple groups of rubber rollers 94 and scraping columns 95, and the rubber rollers 94 and scraping columns 95 scrape and clean the inner wall of the cable protection tube.

[0053] After the expanding die 7 expands the port of the cable protection tube, the hydraulic rod 40 is started to drive the sliding base 3 and the fixing fixture 4 to slide in the opposite direction along the horizontal direction of the slide groove 2, so that the expanding die 7 is out of contact with the inner wall of the cable protection tube port.

[0054] When the fixing clamp 4 slides in the reverse direction, it drives the double rack 15 to slide in the reverse direction. When the double rack 15 slides, it engages with the flat gear 2 101. Under the reverse sliding action of the double rack 15, the flat gear 2 101 produces a reverse rotation effect. When the flat gear 2 101 rotates in the reverse direction, it drives the flat gear 3 103 to rotate in the reverse direction synchronously through the rotating rod 102. When the flat gear 3 103 rotates in the reverse direction, it engages with the rack 1 104. Under the reverse rotation action of the flat gear 3 103, the rack 104 produces a reverse sliding effect. When the rack 104 slides in the reverse direction, it drives the push rod 105 to slide in the reverse direction synchronously, so that the push rod 105 slides in the reverse direction along the mounting bracket 91 horizontally.

[0055] When the push rod 105 slides in the opposite direction, it pulls the support plate 109 through the connecting rod 107 and the connecting rod 2 108. At the same time, under the limiting action of the limiting rod 1010, the support plate 109 slides in the direction of the limiting rod 1010. The support plate 109 slides and is pushed out from the surface of the positioning ring 106. When the support plate 109 slides and is pushed out, it approaches and contacts the inner wall of the expanded cable protection tube port, and provides auxiliary support for the inner wall of the expanded cable protection tube port, thereby achieving a supporting effect on the inner wall of the expanded cable protection tube port.
