Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, specifically relating to a processing device for automotive brake hard tubes. Background Technology

[0002] The brake hose is a component in the automotive braking system used to transmit hydraulic thrust. Before installing the brake hose into a vehicle, it needs to be bent. Only after bending can the brake hose be easily installed into the complex automotive chassis. A hose bender is used when bending the brake hose. Although current hose benders can bend the brake hose, they still have some shortcomings. Because the installation path of the brake hose is complex and variable, various bending radii are required. However, existing hose benders cannot adjust the bending radius of the brake hose, resulting in poor practicality. To address the above problems, we propose an automotive brake hose processing device. Summary of the Invention

[0003] The purpose of this invention is to provide an automotive brake rigid tube processing device to solve the problems existing in the prior art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A processing device for automotive brake hard tubes includes a base plate. The upper end of the base plate has multiple stacked circular plates, the diameters of which decrease at equal intervals from bottom to top, and the heights of the circular plates are equal. A first rectangular rod is rotatably connected to the upper end of the uppermost circular plate. A horizontal rod is longitudinally slidably connected to the outer side of the first rectangular rod, and the horizontal rod has a first groove matching the first rectangular rod. A vertical rod is laterally slidably connected to the outer side of the horizontal rod, and the vertical rod has a second groove matching the horizontal rod. A bending member is fixedly connected to the lower end of the vertical rod, and the side of the bending member has an annular groove.

[0006] The crossbar has a first rectangular groove at its left end and a second rectangular groove at its right end. A slider is longitudinally slidably connected in the second rectangular groove. The slider has an inclined surface on its lower left side. A second rectangular rod is slidably connected left and right in the first rectangular groove. An abutment plate is fixedly connected to the middle of the second rectangular rod. A third sliding groove for the abutment plate to slide left and right is opened in the crossbar. A spring is sleeved on the outside of the second rectangular rod and abuts against the left end of the abutment plate. A first insert is fixedly connected to the left end of the second rectangular rod. A first receiving groove for the second rectangular rod to slide up and down is opened in the first rectangular rod. Several longitudinally distributed first slots are opened at the left end of the first rectangular rod. The number of first slots is the same as the number of circular plates. The distance between two adjacent first slots is equal to the height of the circular plates.

[0007] The upper end of the slider is fixedly connected to a strip plate extending towards one side of the first rectangular rod. The side of the strip plate is provided with a plurality of second inserts at equal intervals along its length. The distance between two adjacent second inserts is equal to the radius difference between two adjacent circular plates. The upper end of the crossbar is provided with a second receiving groove that matches the strip plate and the second inserts. The top wall of the second slide groove is provided with a second slot that matches the second inserts. The top wall of the second slide groove is provided with a third receiving groove that matches the strip plate.

[0008] A vertical plate is fixed to one side of the upper end of the base plate, and the vertical plate has a number of insertion holes that correspond one-to-one with the side of the circular plate.

[0009] The base plate has four through holes that extend vertically.

[0010] The upper end of the first rectangular rod is fixed with a lateral limiting plate for preventing the crossbar from detaching from the first rectangular rod.

[0011] The right end of the crossbar is fixed with a vertical limiting plate to prevent the vertical bar from detaching from the crossbar.

[0012] The upper end of the vertical rod has a vertical groove that communicates with the second slot, and a plug rod is inserted into the vertical groove.

[0013] The lower end of the insertion rod is rotatably connected to a ball bearing.

[0014] A handle extending to the right is fixed to the upper rear end of the vertical rod.

[0015] The vertical groove has a rectangular cross-section, and the insertion rod has a rectangular cross-section that matches the vertical groove. A pressure plate extending towards the handle is fixed to the upper end of the insertion rod.

[0016] This invention provides a processing device for automotive brake hard tubes.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1

[0029] like Figure 1-7 As shown, an automotive brake hard tube processing device of the present invention includes a base plate 1. The upper end of the base plate 1 is provided with a plurality of stacked circular plates 2. The diameter of the plurality of circular plates 2 decreases at equal intervals from bottom to top. The height of the plurality of circular plates 2 is equal. The upper end of the uppermost circular plate 2 is rotatably connected to a first rectangular rod 21. A crossbar 22 is longitudinally slidably connected to the outer side of the first rectangular rod 21. A transverse limiting plate 61 for limiting the crossbar 22 from disengaging from the first rectangular rod 21 is fixed to the upper end of the first rectangular rod 21.

[0030] The crossbar 22 has a first groove 221 that matches the first rectangular bar 21. A vertical bar 23 is slidably connected to the outer side of the crossbar 22. A vertical limiting plate 62 for limiting the vertical bar 23 from disengaging from the crossbar 22 is fixed to the right end of the crossbar 22.

[0031] The vertical rod 23 has a second sliding groove 231 that matches the horizontal rod 22. A bending member 232 is fixedly connected to the lower end of the vertical rod 23. An annular groove 233 is provided on the side of the bending member 232.

[0032] A first rectangular groove 3 is provided at the left end of the crossbar 22, and a second rectangular groove 31 is provided at the right end of the first rectangular groove 3. A slider 32 is longitudinally slidably connected in the second rectangular groove 31. The lower left side of the slider 32 has an inclined surface 33. A second rectangular rod 34 is slidably connected in the first rectangular groove 3. An abutment plate 35 is fixedly connected in the middle of the second rectangular rod 34. A third sliding groove 351 for the abutment plate 35 to slide left and right is provided in the crossbar 22. A spring 36 is sleeved on the outside of the second rectangular rod 34 and abuts against the left end of the abutment plate 35. A first insert block 37 is fixedly connected to the left end of the second rectangular rod 34. A first receiving groove 371 for the second rectangular rod 34 to slide up and down is provided in the first rectangular rod 21. Several longitudinally distributed first slots 39 are provided at the left end of the first rectangular rod 21. The number of first slots 39 is the same as the number of circular plates 2. The distance between two adjacent first slots 39 is equal to the height of the circular plate 2.

[0033] A strip 4 extending toward one side of the first rectangular rod 21 is fixed to the upper end of the slider 32. Multiple second inserts 41 are equidistantly arranged on the side of the strip 4 along its length direction. The distance between two adjacent second inserts 41 is equal to the radius difference between two adjacent circular plates 2. A second receiving groove 411 matching the strip 4 and the second inserts 41 is opened at the upper end of the crossbar 22. A second slot 42 matching the second inserts 41 is opened on the top wall of the second slide groove 231. A third receiving groove 43 matching the strip 4 is opened on the top wall of the second slide groove 231.

[0034] A vertical plate 5 is fixed to one side of the upper end of the base plate 1. The vertical plate 5 has several insertion holes 51 that correspond one-to-one with the side of the circular plate 2.

[0035] In its natural state, the left end of the spring 36 will abut against the left wall of the third slide groove 351, thereby pushing the abutment plate 35 to the right. This causes the abutment plate 35 to drive the right end of the second rectangular rod 34 to abut against the inclined surface 33 of the slider 32. In this state, if the first insert 37 is aligned with one of the first slots 39, the first insert 37 will be inserted into the first slot 39. In this state, the first insert 37 can limit the horizontal bar 22, fixing it on the first rectangular rod 21 and preventing it from moving up and down. Under the guidance of the inclined surface 33, the slider 32 will be pushed upward, causing one of the second inserts 41 to be inserted into the second slot 42, thereby restricting the vertical rod 23 from sliding left and right on the horizontal rod 22.

[0036] By adjusting the up and down position of the bending member 232 and the distance between the bending member 232 and the first rectangular rod 21, the bending member 232 can be made to abut against the side wall of the circular plate 2 with different radii.

[0037] When the bent part 232 abuts against the side wall of the circular plate 2, the annular groove 233 will form a limiting cavity with the side wall of the circular plate 2.

[0038] When it is necessary to adjust the vertical position of the bent component 232, the horizontal bar 22 can be adjusted vertically relative to the first rectangular bar 21. When it is necessary to adjust the distance between the bent component 232 and the first rectangular bar 21, the vertical bar 23 can be adjusted horizontally relative to the horizontal bar 22.

[0039] During adjustment, press the strip 4 downwards. After the second insert 41 on the strip 4 exits the second slot 42, the vertical rod 23 can slide left and right on the horizontal rod 22. This allows adjustment of the distance between the bent piece 232 and the first rectangular rod 21. When the strip 4 is pressed down, the slider 32 on the lower side of the strip 4 will be pressed down at the same time. The inclined surface 33 on the lower side of the slider 32 will force the second rectangular rod 34 to move to the left against the elastic force of the spring 36. When the second insert 41 exits the second slot 42, the first insert 37 will exit the first slot 39 at the same time. At this time, the up and down position of the bent piece 232 can be adjusted.

[0040] When the brake tube needs to be bent, select the radius to be bent and adjust the position of the bending member 232 so that it abuts against the circular plate 2 of that radius. Then rotate the position of the crossbar 22 so that the limiting cavity is aligned with the corresponding insertion hole 51. Then pass the brake tube through the limiting cavity and the corresponding insertion hole 51. Then push the crossbar 22 so that it rotates around the center of the circular plate 2. During this process, the bending member 232 will force the brake tube to bend around the circular plate 2, thereby bending the brake tube. After bending to the appropriate position, press down the strip 4 to unlock the vertical bar 23. Then slide the vertical bar 23 away from the first rectangular bar 21 so that the bending member 232 is disengaged from the circular plate 2. At this time, the brake tube can be taken out, and the bending process is completed.

[0041] When bending to other radii is required, the position of the bending part 232 is adjusted so that it abuts against the circular plate 2 of the corresponding radius, and then the bending process is carried out according to the bending steps described above.

[0042] The base plate 1 has four through holes 6 that extend vertically through the base plate. The through holes 6 can be used to install bolts to fix the entire device to other planes.

[0043] Example 2

[0044] This embodiment makes further improvements based on the previous embodiment. As shown in the figure, the upper end of the vertical rod 23 is provided with a vertical groove 63 that communicates with the second slot 42. A plug rod 64 is inserted into the vertical groove 63. A ball bearing 65 is rotatably connected to the lower end of the plug rod 64. A handle 66 extending to the right is fixedly connected to the upper side of the rear end of the vertical rod 23. The cross-section of the vertical groove 63 is rectangular. The cross-section of the plug rod 64 is a rectangle that matches the vertical groove 63. A pressure plate 67 extending to the handle 66 is fixedly connected to the upper end of the plug rod 64.

[0045] When pushing the horizontal bar 22, the user can hold the handle 66 and push it, causing the handle 66 to push the horizontal bar 22 through the vertical bar 23. This saves more physical effort compared to directly pushing the horizontal bar 22. In addition, when it is necessary to press down the strip 4 to unlock the horizontal bar 22 and the vertical bar 23, the user can use their thumb to press down the pressure plate 67 while holding the handle 66. The pressure plate 67, together with the insertion rod 64 and the ball bearing 65, presses down the strip 4, allowing the user to perform the unlocking operation with one hand. While unlocking, the user can use the handle 66 to control the vertical bar 23 to move back and forth to adjust the distance between the bent piece 232 and the first rectangular bar 21. The user can also use the handle 66 to control the vertical bar 23 to move up and down, thereby moving the horizontal bar 22 up and down to adjust the vertical position of the bent piece 232. This allows the user to adjust the position of the bent piece 232 with one hand, which can improve work efficiency to a certain extent.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
