Description

Technical Field

[0001] This utility model belongs to the technical field of flaring devices, specifically a flaring device for processing automotive pipe fittings. Background Technology

[0002] After automotive oil pipes, air pipes, water pipes, air conditioning pipes, and other pipes are manufactured, a pipe expander is usually used to widen one end of the pipe to increase its diameter, making it easier to connect the pipe to other pipes.

[0003] When using a pipe expander, the pipe to be expanded is placed on the clamp of the expander. The position of the pipe is fixed by the hydraulic clamp, and the hydraulic equipment on the other side pushes the expander head into the inside of the pipe to enlarge the pipe diameter. After the pipe diameter is enlarged, it is usually necessary to chamfer the outside of the connection between the enlarged part and the normal position of the pipe. Existing flaring devices cannot chamfer the outside of the pipe during the expansion process, and other equipment is required to further process the pipe, which increases the workflow and cost, resulting in the problem of low practicality of the flaring device. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a flaring device for processing automotive pipe fittings. It solves the problem that after the pipe diameter is enlarged, it is usually necessary to chamfer the outer side of the connection between the enlarged pipe and the normal pipe diameter position. Existing flaring devices cannot chamfer the outer side of the pipe during the diameter enlargement process, requiring the use of other equipment to further process the pipe, which increases the workflow and cost, resulting in low practicality of the flaring device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flaring device for processing automotive pipe fittings, comprising a body, a placement platform fixedly connected to the top of the body, a first hydraulic rod disposed on the side of the top of the body near the placement platform, a pressure block fixedly connected to the output rod of the first hydraulic rod, the pressure block being located above the placement platform, a flaring head slidably connected to the top of the body, a second hydraulic rod disposed on the side of the top of the body near the flaring head, the output rod of the second hydraulic rod being fixedly connected to one side of the flaring head, and an auxiliary device disposed on one side of the placement platform. The auxiliary device includes two grooved rods, one end of which is fixedly connected to one side of the placement platform. A sliding rod is slidably connected to the inner wall of each grooved rod. A rotating shaft is rotatably connected to the end of each sliding rod furthest from the grooved rod. An H-shaped rod is fixedly connected to the outer surface of each rotating shaft, with one end of the H-shaped rod engaging the upper and lower sides of the grooved rod. A chamfered ring is fixedly connected to the side of the two rotating shafts closest to each other. The inner edge of the chamfered ring is beveled. A spring is provided on one side of each sliding rod, with both ends of the spring fixedly connected to one side of the inner wall of the grooved rod and one end of the sliding rod, respectively.

[0006] As a further embodiment of this utility model: a round rod is fixedly connected to the inner wall of the groove rod, and the sliding rod slides on the outer surface of the round rod.

[0007] As a further embodiment of this utility model: reinforcing rods are fixedly connected to the upper and lower sides of the H-shaped rod, and the end of the reinforcing rod away from the H-shaped rod is fixedly connected to one side of the chamfered ring.

[0008] As a further embodiment of this utility model: a groove is provided on one side of the sliding rod, and the groove is located on the outer side of the end of the sliding rod away from the groove.

[0009] As a further embodiment of this utility model: a positioning device is provided on one side of the placement platform. The positioning device includes a rectangular rod, one end of which is fixedly connected to one side of the placement platform. An L-shaped rod is slidably connected to the inner wall of the rectangular rod, and a screw is rotatably connected to one end of the inner wall of the rectangular rod. The outer surface of the screw is threadedly connected to the inner wall of the L-shaped rod.

[0010] As a further embodiment of this utility model: an operating block is fixedly connected to the end of the screw away from the rectangular rod, and two opposing protrusions are provided on the outer surface of the operating block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This flaring device, through the installation of an auxiliary device, uses a chamfering ring installed on one side of the placement platform. Rotating the chamfering ring adjusts the right-angled or beveled side of the chamfering ring to face outwards. When the flaring head is used to flare the pipe fitting, the outer surface of the flared end of the pipe fitting is squeezed by the chamfering ring at the connection point with the unflared surface. The chamfering ring chamfers the outer surface of the pipe fitting at the flared position according to the shape of one side of the chamfering ring, eliminating the need for additional equipment to chamfer the outer surface of the pipe fitting, thus improving the practicality of using the flaring device to process pipe fittings.

[0013] 2. This flaring device, by setting a positioning device, fixes the pipe fitting on the outer surface of the placement platform. By rotating the screw, the sliding rod is controlled to move towards the pipe fitting on the outer surface of the screw and the inner wall of the rectangular rod, so that one end of the L-shaped rod abuts against the outer side of one end of the pipe fitting, further fixing the rear position of the pipe fitting and minimizing the movement of the pipe fitting when the flaring head enters the inside of the pipe fitting for flaring.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4As shown, this utility model provides a technical solution: a flaring device for processing automotive pipe fittings, including a body 1, a placement platform 4 fixedly connected to the top of the body 1, a first hydraulic rod 5 disposed on the side of the top of the body 1 near the placement platform 4, a pressure block 6 fixedly connected to the output rod of the first hydraulic rod 5, the pressure block 6 being located above the placement platform 4, a flaring head 8 slidably connected to the top of the body 1, a second hydraulic rod 7 disposed on the side of the top of the body 1 near the flaring head 8, the output rod of the second hydraulic rod 7 being fixedly connected to one side of the flaring head 8, an auxiliary device 2 disposed on one side of the placement platform 4, the auxiliary device 2 including two grooved rods 21, one end of the two grooved rods 21 being fixedly connected to one side of the placement platform 4, and sliding rods 22 slidably connected to the inner wall of the grooved rods 21. The ends of the sliding rod 22 away from the groove rod 21 are rotatably connected to the shafts 25. H-shaped rods 26 are fixedly connected to the outer surface of the shafts 25, with one end of the H-shaped rod 26 engaged on the upper and lower sides of the groove rod 21. Chamfering rings 23 are fixedly connected to the sides of the two shafts 25 that are close to each other. One edge of the inner wall of the chamfering ring 23 is beveled. A spring 24 is provided on one side of the sliding rod 22, with both ends of the spring 24 fixedly connected to one side of the inner wall of the groove rod 21 and one end of the sliding rod 22, respectively. By using the chamfering ring 23, when flaring the automotive fitting, first pull the chamfering ring 23 at one end of the sliding rod 22 to control the sliding rod 22 to slide outwards on the inner wall of the groove rod 21 and stretch the spring 24, causing one end of the H-shaped rod 26 to move away from the outer surface of the groove rod 21. Then, push the chamfering ring 23 through the shafts... 25. Rotate the chamfering ring 23 so that either the right-angled or beveled face faces outward. Then release the chamfering ring 23. The spring 24 returns to its original shape, pulling the sliding rod 22 inward so that one end of the H-shaped rod 26 is locked on the upper and lower sides of the groove rod 21, fixing the chamfering ring 23 in the position outside the groove rod 21. Then place the automotive fitting on the outer surface of the placement platform 4, push the fitting to move so that the end of the fitting that needs to be flared passes through the inside of the chamfering ring 23 and adjust the position of the fitting. Then operate the first hydraulic rod 5 to extend and control the pressure block 6 to descend, so that the pressure block 6 presses against the outside of the fitting on the outer surface of the placement platform 4, fixing the position of the fitting. Then operate the second hydraulic rod 7 to control the flaring head 8 to move towards the fitting, so that the flaring head 8 slowly enters into the inside of one end of the fitting, and flaring the fitting through the flaring head 8. When the flaring head 8 is near the chamfering ring 23, the outer surface of the flared end of the pipe fitting will be squeezed by the chamfering ring 23 at the junction with the unflared surface. Based on the shape of one side of the chamfering ring 23, the outer surface of the pipe fitting at the flaring position is chamfered. After flaring, the second hydraulic rod 7 is operated to retract, causing the flaring head 8 to move away from the inside of the pipe fitting. Then, the first hydraulic rod 5 is operated to control the pressure block 6 to rise away from the surface of the pipe fitting, pulling the pipe fitting out. By setting the auxiliary device 2, and by installing the chamfering ring 23 on one side of the placement platform 4, rotating the chamfering ring 23 can adjust the right-angled or beveled side of the chamfering ring 23 to face outwards, so that when the flaring head 8 flares the pipe fitting, the outer surface of the flared end of the pipe fitting at the junction with the unflared surface is squeezed by the chamfering ring 23.Based on the shape of one side of the chamfering ring 23, the outer side of the flared section of the pipe fitting is chamfered, eliminating the need for additional equipment to chamfer the outer side of the pipe fitting and improving the practicality of using a flaring device for pipe fitting processing;

[0021] A round rod 27 is fixedly connected to the inner wall of the groove rod 21. The sliding rod 22 slides on the outer surface of the round rod 27. When the sliding rod 22 is pulled, it will move on the outside of the round rod 27. The round rod 27 can further limit the angle between the sliding rod 22 and the groove rod 21, and avoid the angle between the sliding rod 22 and the groove rod 21 from deflection as much as possible. The upper and lower sides of the H-shaped rod 26 are respectively fixedly connected to the reinforcing rod 28. The end of the reinforcing rod 28 away from the H-shaped rod 26 is fixedly connected to the side of the chamfer ring 23. By setting the reinforcing rod 28, the outer shape of the chamfer ring 23 can be reinforced, and the structural strength of the outer surface of the chamfer ring 23 can be improved. A groove 29 is opened on one side of the sliding rod 22. The groove 29 is located on the outside of the end of the sliding rod 22 away from the groove rod 21. By pinching the groove 29 at one end of the sliding rod 22, it is easier to pull the sliding rod 22 and control its movement position.

[0022] A positioning device 3 is provided on one side of the placement platform 4. The positioning device 3 includes a rectangular rod 31, one end of which is fixedly connected to one side of the placement platform 4. An L-shaped rod 32 is slidably connected to the inner wall of the rectangular rod 31. A screw 33 is rotatably connected to one end of the inner wall of the rectangular rod 31. The outer surface of the screw 33 is threadedly connected to the inner wall of the L-shaped rod 32. When flaring the pipe fitting, after placing the pipe fitting on the outer surface of the placement platform 4 and fixing it in position by the pressure block 6, the screw 33 can be rotated to control the sliding rod 22 on the outer surface of the screw 33. The inner wall of the rectangular rod 31 moves toward the pipe fitting, so that one end of the L-shaped rod 32 abuts against the outer side of one end of the pipe fitting, further fixing the rear position of the pipe fitting, and minimizing the movement of the pipe fitting position when the flaring head 8 enters the pipe fitting for flaring. The end of the screw 33 away from the rectangular rod 31 is fixedly connected to the operating block 34. The outer surface of the operating block 34 is provided with two opposing protrusions. Holding the two protrusions on the outer surface of the operating block 34 makes it easier to rotate the operating block 34 to control the rotation of the screw 33 and prevents the hand from slipping.

[0023] The working principle of this utility model is as follows: When flaring the automotive pipe fitting, first pull the chamfer ring 23 at one end of the sliding rod 22 to control the sliding rod 22 to slide outward on the inner wall of the groove rod 21 and stretch the spring 24 so that one end of the H-shaped rod 26 moves away from the outer surface of the groove rod 21. Then push the chamfer ring 23 to rotate through the rotating shaft 25 to select the right angle or beveled surface of the chamfer ring 23 to face outward. Then release the chamfer ring 23, and the spring 24 returns to its original shape, pulling the sliding rod 22 inward so that one end of the H-shaped rod 26 is stuck on the upper and lower sides of the groove rod 21, fixing the position of the chamfer ring 23 on the outside of the groove rod 21. Then place the automotive pipe fitting on the outer surface of the placement platform 4, push the pipe fitting to move so that the end of the pipe fitting that needs to be flared passes through the inside of the chamfer ring 23 and adjust the position of the pipe fitting. Then operate the first hydraulic rod 5 to extend and control the pressure block 6 to descend, so that the pressure block 6 presses on the outside of the pipe fitting on the outer surface of the placement platform 4. After fixing the position of the pipe fitting, rotate screw 33 to control sliding rod 22 to move towards the pipe fitting on the outer surface of screw 33 and the inner wall of rectangular rod 31, so that one end of L-shaped rod 32 abuts against the outer side of one end of the pipe fitting, further fixing the rear position of the pipe fitting. Then, operate the second hydraulic rod 7 to control flaring head 8 to move towards the pipe fitting, so that flaring head 8 slowly enters the interior of one end of the pipe fitting, and flaring the pipe fitting through flaring head 8. When one end of flaring head 8 is close to chamfering ring 23, the outer side of the connection between the outer surface of the flared end of the pipe fitting and the unflared surface will be squeezed by chamfering ring 23. According to the shape of one side of chamfering ring 23, chamfer the outer side of the flared position of the outer surface of the pipe fitting. After flaring is completed, operate the second hydraulic rod 7 to retract and drive flaring head 8 away from the interior of the pipe fitting. Then, operate the first hydraulic rod 5 to control pressure block 6 to rise away from the surface of the pipe fitting, pull the pipe fitting out.
