Description

Technical Field

[0001] This invention relates to a hydraulic hose stripper, belonging to the field of hose stripping technology. Background Technology

[0002] Hydraulic hoses, also known as hydraulic oil pipes, hydraulic flexible hoses, high-pressure hoses, hydraulic tubes, steel wire high-pressure hoses, steel wire braided hoses, and steel wire spiral hoses, are covered with a rubber layer. In some processing steps, it is necessary to remove the outer rubber layer, which requires the use of rubber stripping equipment. Traditional rubber stripping equipment for hydraulic hoses requires adjusting the blade to the required stripping depth and fixing it before controlling the end of the hydraulic hose to be stripped under the action of the blade.

[0003] Chinese Patent Publication No. CN220945653U discloses a base, mounting plate, cylinder, clamp, collection box, mounting ring, two blades, two adjustment components (I, II, III), and a drive component. The mounting plate and collection box are fixedly mounted on the base. The cylinder is rotatably mounted on the mounting plate and is adapted to the collection box. The drive component is mounted on the mounting plate and connected to the cylinder. The mounting ring is fixedly mounted on the cylinder. This invention has the following advantages and effects: it can feed and peel rubber from hydraulic hoses requiring stripping, and simultaneously extract and collect the rubber particles peeled off by the blades, effectively preventing waste from scattering during the peeling process. It also allows for real-time adjustment of the peeling depth of the blades and facilitates blade replacement.

[0004] However, when the above technology is used, it lacks an automatic centering and linkage feeding structure. It relies on manual pushing of the high-pressure rubber hose into the dangerous area of ​​the high-speed rotating blade. This operation not only poses a high safety hazard to the worker's hands, but also makes it difficult to maintain a constant feeding speed and centering accuracy. This can easily lead to uneven rubber peeling at the end of the hose or even cutting the internal steel wire layer, reducing the peeling yield and production efficiency of continuous batch processing.

[0005] Therefore, a hydraulic hose peeling machine is proposed. Summary of the Invention

[0012] More preferably, the left and right sides of the transmission rod surface are movably connected to support blocks via bearings, and the rear sides of the two support blocks are fixedly installed on the rear side of the housing cavity.

[0013] More preferably, guide slide rods are fixedly installed on both the left and right sides of the top of the base, and the left and right sides of the bottom of the movable frame are slidably connected to the surface of the guide slide rods.

[0018] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0019] I. This invention, through the setting of a positioning and feeding component, and the output of a drive motor, enables the connecting rod to rotate. The swing rod and the movable rod cooperate to drive the clamping plate to move inward, thereby achieving the clamping and fixing of hydraulic hoses of different sizes. Subsequently, through the extension of the hydraulic cylinder, the housing and the hydraulic hose can move backward synchronously, so that the area of ​​the hydraulic hose to be cut moves to the inside of the cutting blade. This allows the operator to keep their hands away from the cutting blade when placing or removing the hydraulic hose, avoiding accidental cuts. It also improves the convenience and stability of cutting hydraulic hoses. By setting up a peeling component, through the retraction of the cylinder, the lifting block and the linkage rod cooperate to drive the fixing plate and the cutting blade to move downward and inward synchronously, bringing the cutting blade closer to the hydraulic hose. Through the output of the rotary motor, the cutting blade performs a circumferential cut on the hydraulic hose. At the same time, due to the movable nature of the cutting blade, circumferential cutting of hydraulic hoses of different sizes can be achieved, improving the convenience and flexibility of peeling the hydraulic hose.

[0020] II. This invention, by setting a protective pad, avoids scratching the surface of the hydraulic hose when the clamping plate fixes it due to the characteristics of its material. By setting a guide groove, the movement of the moving cross plate can be limited to prevent it from deviating in direction during movement. By setting a support block, the transmission rod can be supported to prevent it from falling off after long-term use. By setting a guide slide rod, the moving frame can be guided to prevent it from changing direction during movement. By setting a mounting bolt, the cutting tool can be quickly disassembled and assembled, facilitating disassembly and maintenance of the cutting tool after long-term use. By setting a limit rod, the movement of the sliding block can be limited to prevent it from deviating in direction during movement. By setting a positioning rod, the movement of the lifting block can be limited to ensure the accuracy of the lifting block's direction of movement.

[0032] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figures 1-7 As shown, this embodiment of the invention provides a hydraulic hose peeling machine, including a base 1. A vertical plate 4 is fixedly installed on the top of the base 1. Cutting blades 5 are provided on the front side of each vertical plate 4. A positioning and feeding assembly 2 is provided on the surface of the base 1. The positioning and feeding assembly 2 includes a movable frame 202, which is located on the top of the base 1. A housing 203 is fixedly installed on the top of the movable frame 202. A transmission rod 205 is movably connected to the inner cavity of the housing 203. Transmission bevel gears 206 are fixedly installed on the left and right sides of the surface of the transmission rod 205. A transmission bevel gear 206 is movably connected to the rear side of the inner cavity of the housing 203. The surfaces of the two driven bevel gears 206 mesh with the surfaces of the two driven bevel gears 207. The rear sides of the two driven bevel gears 207 are fixedly connected to the connecting rods 208. The front and rear sides of the surfaces of the two connecting rods 208 are fixedly installed with swing rods 209. The other ends of the four swing rods 209 are movably connected to the movable rods 210. The other ends of the four movable rods 210 are movably connected to the movable cross plate 211. The tops of the two movable cross plates 211 are fixedly installed with the mounting rods 212. The other ends of the four mounting rods 212 are fixedly installed with the clamping plates 213.

[0036] A peeling assembly 3 is provided on the surface of the vertical plate 4. The peeling assembly 3 includes a peeling frame 302, which is movably connected to the front side of the vertical plate 4. A cylinder 303 is fixedly installed on the front side of the peeling frame 302. A lifting block 304 is fixedly installed on the top of the cylinder 303. A linkage rod 305 is movably connected to both sides of the lifting block 304. A sliding block 306 is movably connected to the other end of the linkage rod 305. A fixing rod 307 is fixedly installed on the front side of each of the two sliding blocks 306. A fixing plate 308 is fixedly installed on the other end of each of the two fixing rods 307. A rotary motor 301 is fixedly installed on the rear side of the vertical plate 4. The output end of the rotary motor 301 is fixedly connected to the rear side of the peeling frame 302. The outlet adopts a hollow main shaft structure, with a rotary pneumatic connector (not shown in the figure) inside. An external static air source continuously supplies air to the rotating cylinder 303 through the rotary pneumatic connector, thereby avoiding the phenomenon of air pipe entanglement and breakage when the peeling frame 302 rotates continuously. A hydraulic cylinder 201 is fixedly installed on the front side of the base 1. The rear side of the hydraulic cylinder 201 is fixedly connected to the front side of the housing 203. A drive motor 204 is fixedly connected to the right side of the housing 203. The output end of the drive motor 204 is fixedly connected to the right side of the transmission rod 205. A control switch panel 6 is fixedly installed on the front side of the base 1. The output end of the control switch panel 6 is electrically connected to the input end of the hydraulic cylinder 201, the drive motor 204, and the rotary motor 301.

[0037] By setting up the positioning and feeding component 2, the output of the drive motor 204 causes the connecting rod 208 to rotate. The swing rod 209 cooperates with the movable rod 210, thereby driving the clamping plate 213 to move inward, realizing the clamping and fixing of hydraulic hoses of different sizes. Subsequently, through the extension of the hydraulic cylinder 201, the housing 203 and the hydraulic hose can move backward synchronously, so that the area to be cut on the hydraulic hose moves to the inside of the cutting tool 5. This allows the operator to keep their hands away from the cutting tool 5 when placing or removing the hydraulic hose, avoiding injury from the cutting tool 5. This design prevents accidental cuts to personnel and improves the convenience and stability of hydraulic hose cutting. By setting up the peeling component 3, the retraction of the cylinder 303 allows the lifting block 304 and the linkage rod 305 to work together to drive the fixed plate 308 and the cutting blade 5 to move synchronously downward and inward, bringing the cutting blade 5 closer to the hydraulic hose. Through the output of the rotary motor 301, the cutting blade 5 performs a circumferential cut on the hydraulic hose. At the same time, due to the movable nature of the cutting blade 5, it can perform circumferential cuts on hydraulic hoses of different sizes, improving the convenience and flexibility of peeling the hydraulic hose.

[0038] Example 2

[0039] like Figures 1-8As shown, in one embodiment, protective pads 214 are fixedly installed on the surfaces of the four clamping plates 213. The protective pads 214 are made of rubber. Guide grooves 215 are provided on the left and right sides of the top of the movable frame 202. The bottoms of the two movable horizontal plates 211 are slidably connected in the guide grooves 215. Support blocks 216 are movably connected to the left and right sides of the surface of the transmission rod 205 through bearings. The rear sides of the two support blocks 216 are fixedly installed on the rear side of the inner cavity of the housing 203. Guide rods 214 are fixedly installed on the left and right sides of the top of the base 1. 17. The left and right sides of the bottom of the movable frame 202 are slidably connected to the surface of the guide slide rod 217. The surfaces of the two fixed plates 308 are threaded with mounting bolts 309. The other end of the mounting bolts 309 is threaded to the inner surface of the cutting tool 5. The front side of the peeling frame 302 is fixedly installed with a limit rod 310. The two sliding blocks 306 are slidably connected to the surface of the limit rod 310. The left and right sides of the surface of the peeling frame 302 are fixedly installed with positioning rods 311. The lifting block 304 is slidably connected to the surface of the two positioning rods 311.

[0040] By setting a protective pad 214, due to the characteristics of its material, scratches can be avoided on the surface of the hydraulic hose when the clamping plate 213 is used to fix the hydraulic hose. By setting a guide groove 215, the movement of the moving cross plate 211 can be limited to prevent it from deviating in direction during movement. By setting a support block 216, the transmission rod 205 can be supported to prevent it from falling off after long-term use. By setting a guide slide rod 217, the moving frame 202 can be guided to prevent it from changing direction during movement. By setting a mounting bolt 309, the cutting tool 5 can be quickly disassembled and assembled, making it convenient for disassembly and maintenance after long-term use. By setting a limit rod 310, the movement of the sliding block 306 can be limited to prevent it from deviating in direction during movement. By setting a positioning rod 311, the movement of the lifting block 304 can be limited to ensure the accuracy of the direction of movement of the lifting block 304.

[0041] In operation, the present invention works as follows: First, the hydraulic hose is placed inside the clamping plate 213. Then, through the output of the drive motor 204, the transmission rod 205 drives the transmission bevel gear 206 to rotate. When the transmission bevel gear 206 rotates, it engages with the driven bevel gear 207. Since the driven bevel gears 207 on the left and right sides are arranged in opposite directions, when the transmission rod 205 rotates in one direction, the driven bevel gears 207 on the left and right sides drive their respective connecting rods 208 to rotate in opposite directions. When the connecting rods 208 rotate, they cause... The left and right swing rods 209 swing in opposite directions in a mirror-symmetrical manner. At this time, the swing rods 209 cooperate with the movable rod 210, causing the movable rod 210 to push the moving cross plate 211, the mounting rod 212, and the clamping plate 213 to move inward synchronously. At this time, the clamping plate 213 clamps and fixes the hydraulic hose. Then, through the extension of the hydraulic cylinder 201, the housing 203 moves backward. When the housing 203 moves, it simultaneously drives the moving frame 202 and the hydraulic hose to move backward synchronously, so that the hydraulic hose can be peeled off as required. The area moves to the inside of the cutting tool 5, and then the lifting block 304 moves downward by the retraction of the cylinder 303. At this time, the lifting block 304 cooperates with the linkage rod 305, and the linkage rod 305 drives the sliding block 306 and the fixed rod 307 to move inward synchronously. In order to accurately control the radial feed depth of the tool (i.e., the peeling thickness of the rubber layer), limit rings (not shown in the figure) are threaded on both ends of the limit rod 310. When the sliding block 306 moves inward and abuts against the limit rings, it stops. The operator can adjust the peeling depth of different pipe diameters by turning the position of the limit screw ring to prevent cutting the internal steel wire layer. When the fixed rod 307 moves, it will drive the fixed plate 308 and the cutting tool 5 to move inward synchronously. The cutting tool 5 cuts the surface of the hydraulic hose. At the same time, the rotary motor 301 outputs output, causing the peeling frame 302 to rotate. When the peeling frame 302 rotates, the cutting tool 5 rotates synchronously, so that the cutting tool 5 performs a circumferential cut on the hydraulic hose, realizing the peeling work of the hydraulic hose.

[0042] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
