Description

[0002] In the production and application of hoses, the splicing process at the hose ends is a critical step, the quality of which directly affects the tightness and reliability of the connection between the hose and other components.

[0003] Existing hose flaring devices have certain shortcomings in structural design and functional implementation. For example, traditional clamping devices are mostly designed with fixed spacing, which makes it difficult to accurately adapt to hoses with different inner diameters. This can easily lead to insufficient clamping force causing hose displacement or excessive clamping force damaging the hose. At the same time, the flaring accuracy is difficult to guarantee, the operation is not convenient and efficient, and the process is cumbersome and has low precision, making it difficult to meet the high precision requirements of different hose specifications for flaring dimensions. In addition, for some hoses with harder or more tough materials, the lack of a heating pretreatment step can easily lead to problems such as end cracking and uneven deformation during flaring. Therefore, we propose a hose flaring device. Utility Model Content

The clamping block is mounted on the side of the bracket.

[0008] Preferably, the top of the fixing base has a through hole, and the bracket is slidably installed in the through hole.

[0009] Preferably, the adjusting mechanism includes a handle, a worm, a third lead screw, a worm wheel, and a slider.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1A hose end-opening device includes a base 1, a fixed seat 2 fixed to the top of the base 1, and two sets of clamping blocks 4 mounted on the fixed seat 2 via a moving mechanism 3. The moving mechanism 3 drives the two sets of clamping blocks 4 to move synchronously towards or away from each other, allowing the two sets of clamping blocks 4 to fit against the hose. This enables the clamping blocks 4 to precisely clamp or loosen hoses of different inner diameters, preventing displacement of the hose during the end-opening process. An annular heating ring 5 is mounted on the top of the fixed seat 2 to heat the hose end, facilitating subsequent end-opening operations. A movable seat 7 is slidably mounted on the top of the base 1, and a translation mechanism is mounted on the top of the base 1 to drive the movable seat 7 to move horizontally. The piston rod of the hydraulic cylinder 6 drives the movable seat 7 to move horizontally, so that the flaring head 14 approaches and is inserted into the hose port, realizing the flaring operation of the hose port. The top of the movable seat 7 is equipped with a lifting platform 9, and the top of the lifting platform 9 is fixed with a fixed frame 10. The side of the fixed frame 10 is equipped with a second motor 11. The output shaft of the second motor 11 rotates through the fixed frame 10 and is connected to a fixed plate 12. Two flaring heads 14 are slidably installed on the fixed plate 12. The fixed plate 12 is equipped with an adjustment mechanism 13 for driving the two flaring heads 14 to move towards or away from each other. Through the adjustment mechanism 13, the two flaring heads 14 can be driven to move towards or away from each other, thereby adjusting the distance between the two flaring heads 14, which facilitates the precise adjustment of the flaring size of hoses with different inner diameters.

[0022] Reference Figure 2The moving mechanism 3 includes a first motor 31, a first lead screw 32, a first pulley 33, a second lead screw 34, a second pulley 35, a synchronous belt 36, and a bracket 37. The first motor 31 is mounted on the side of the fixed base 2. The output shaft of the first motor 31 rotates through the fixed base 2 and is connected to the first lead screw 32. The first pulley 33 is fixedly sleeved on the first lead screw 32. The second lead screw 34 is rotatably mounted inside the fixed base 2. The second pulley 35 is fixedly sleeved on the second lead screw 34. The first pulley 33 and the second pulley 35 are connected by a synchronous belt 36. Two brackets 37 are sleeved on both the first lead screw 32 and the second lead screw 34 through threads with opposite directions. A through hole is opened at the top of the fixed base 2. The brackets 37 are slidably mounted in the through hole. The clamping block 4 is mounted on the side of the bracket 37. The first motor 31 is started, and the output shaft of the first motor 31 drives the first lead screw 32 to rotate, which in turn drives the first pulley 33 to rotate. The first pulley 33 drives the second pulley 35 to rotate through the synchronous belt 36, which in turn drives the second lead screw 34 to rotate. Through the threaded transmission of the first lead screw 32, the second lead screw 34 and the bracket 37, and the fact that the threads on the first lead screw 32 and the second lead screw 34 have opposite directions of rotation, when the first lead screw 32 and the second lead screw 34 rotate, the bracket 37 will drive the two sets of clamping blocks 4 to move synchronously towards or away from each other along the lead screw 32 and the second lead screw 34, so that the two sets of clamping blocks 4 fit with the hose. This allows the clamping blocks 4 to accurately clamp or loosen hoses with different inner diameters, preventing the hose from shifting during the opening process.

[0023] Reference Figure 3 , Figure 4 The adjusting mechanism 13 includes a handle 131, a worm gear 132, a third lead screw 133, a worm wheel 134, and sliders 135. The worm gear 132 is rotatably mounted inside the fixed plate 12, passing through the fixed plate 12 and connected to the handle 131. The third lead screw 133 is rotatably mounted inside the fixed plate 12, and the worm wheel 134 is fixedly sleeved on the third lead screw 133. The worm gear 132 and the worm wheel 134 mesh and drive each other. Two sliders 135 are sleeved on the third lead screw 133 through threads with opposite directions. A sliding hole is provided on the side of the fixed plate 12, and the sliders 135 are slidably mounted in the sliding hole. The flared head 14 is installed on the side of the slider 135. When the handle 131 is turned, the handle 131 drives the worm 132 to rotate. Through the meshing transmission between the worm 132 and the worm wheel 134, the worm wheel 134 drives the third lead screw 133 to rotate. Through the threaded transmission between the third lead screw 133 and the slider 135, and since the threads on the third lead screw 133 have opposite directions of rotation, when the third lead screw 133 rotates, the two sliders 135 will drive the two flared heads 14 to move towards or away from each other, thereby adjusting the distance between the two flared heads 14. This facilitates precise adjustment of the flared size of hoses with different inner diameters.

[0024] Reference Figure 1The translation mechanism includes a hydraulic cylinder 6 and a guide block 8. The hydraulic cylinder 6 is installed on the top of the base 1. The piston rod of the hydraulic cylinder 6 is fixedly connected to the movable seat 7. The guide block 8 is fixed on the bottom of the movable seat 7. A guide groove is provided on the top of the base 1. The guide block 8 is slidably installed in the guide groove. When the hydraulic cylinder 6 is started, the piston rod of the hydraulic cylinder 6 drives the movable seat 7 to translate, thereby driving the expansion port 14 indirectly installed on the movable seat 7 to approach and insert into the hose port, realizing the opening operation of the hose port.

[0025] Working principle: The hose to be opened is placed between two sets of clamping blocks 4 on the fixed base 2. The first motor 31 is started, and the output shaft of the first motor 31 drives the first lead screw 32 to rotate, which in turn drives the first pulley 33 to rotate. The first pulley 33 drives the second pulley 35 to rotate through the synchronous belt 36, which in turn drives the second lead screw 34 to rotate. Through the threaded transmission of the first lead screw 32, the second lead screw 34 and the bracket 37, and the fact that the threads on the first lead screw 32 and the second lead screw 34 have opposite directions of rotation, when the first lead screw 32 and the second lead screw 34 rotate, the bracket 37 will drive the two sets of clamping blocks 4 to move synchronously towards or away from each other along the lead screw 32 and the second lead screw 34, so that the two sets of clamping blocks 4 fit against the hose. This allows the clamping blocks 4 to accurately clamp hoses of different inner diameters and prevent the hose from shifting during the opening process.

[0026] Depending on the material of the hose and the requirements for flaring, turn on the annular heating coil 5 to preheat the hose end, so that the hose reaches a suitable plastic temperature, generally controlled between 50-80℃ (the specific temperature depends on the hose material), which facilitates the subsequent flaring operation.

[0027] Based on the inner diameter of the hose, turn the handle 131. The handle 131 drives the worm gear 132 to rotate. Through the meshing transmission between the worm gear 132 and the worm wheel 134, the worm wheel 134 drives the third lead screw 133 to rotate. Through the threaded transmission between the third lead screw 133 and the slider 135, and since the threads on the third lead screw 133 rotate in opposite directions, when the third lead screw 133 rotates, the two sliders 135 will drive the two flared ends 14 to move towards or away from each other. This allows for adjustment of the distance between the two flared ends 14, facilitating precise adjustment of the flared size of hoses with different inner diameters.

[0028] When the distance between the expansion joints 14 is adjusted to a suitable size, the hydraulic cylinder 6 is started. The hydraulic cylinder 6 drives the movable seat 7 to move towards the hose port, so that the expansion joints 14 are gradually inserted into the hose port. At the same time, the second motor 11 is started. The second motor 11 drives the fixed plate 12 and the expansion joints 14 to rotate, so that the expansion joints 14 expand the hose port evenly until the required opening size is reached.

[0029] After the splicing operation is completed, the hydraulic cylinder 6 drives the movable seat 7 to move in the opposite direction, so that the splicing head 14 is disengaged from the hose. The first motor 31 is started to rotate in the opposite direction, so that the bracket 37 drives the two sets of clamps 4 to release the hose, and the hose with the spliced ​​end is taken out, completing one splicing operation cycle.

[0030] In this case, the handle can be locked with a set screw. By setting a set screw and a corresponding groove, when locking, tighten the set screw so that its end is embedded in the groove, which can prevent the handle from turning. When unlocking, loosen the set screw so that its end is disengaged from the groove, and the handle can be turned.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
