Description

Technical Field

[0001] This invention belongs to the field of flaring equipment technology, specifically relating to a flaring device for mechanical parts. Background Technology

[0002] Flaring is a stamping process that expands the open end of hollow parts or tubular products outwards. It is mainly used for adjusting the geometry of pipe ends and for assembling and connecting components. This process is divided into two forms: integral flaring and single-piece flaring. Integral flaring is suitable for mass production, while single-piece flaring is widely used in the manufacturing of new energy flat wire motors due to its high flexibility. In PVC pipe processing, a flaring temperature control of 245±5℃ is used.

[0003] When using a copper pipe flaring tool for inspection and flaring, the internal parts are stored inside a box. When using it, the worker needs to manually hold the part and flare the end of the copper pipe. This requires holding the workpiece with both hands, which can cause shaking and accidental flipping, damaging the workpiece. Therefore, it is necessary to improve the subsequent flaring method so that it has a fixed position for processing, making flaring more convenient for workers. Summary of the Invention

[0004] The present invention mainly addresses the technical problems existing in the prior art and provides a flaring device for mechanical parts.

The two side clamps, facing each other to one side, have multiple flared holes of different sizes extending downwards from their tops. One of the side clamps has multiple side positioning holes corresponding to the flared holes on its side. L-shaped sliders are provided at the top of the other ends of both side clamps. The flaring device includes a carriage that is slidably mounted on a feeding rack. A sleeve is provided at the top of the carriage, and a flaring rod is threaded into the sleeve. A lever is provided on each side of the top of the flaring rod. A fourth cavity is provided on the side of the first and second boxes that are far apart from each other. A gripping frame is formed on the side of the fourth cavity corresponding to the first and second boxes, respectively. A through groove is provided in the middle of the gripping frame, located in the first box. The height of the gripping frame on the first box is half that of the first box, and the height of the gripping frame on the second box is the same as that of the second box. Insertion receiving seats are provided on both sides of the fourth cavity inside the second box, and pressure strips are provided on both sides of the top of the corresponding fourth cavity. The insertion receiving seats receive the material feeding frame. A material feeding frame for installing a flaring device is provided on the top of the second box. A discharge slot for discharging the flaring device is opened above the fourth cavity on the material feeding frame. Side sliding grooves for sliding the material feeding frame are opened on the left and right sides. A flipping frame is rotatably connected to the front end of the material feeding frame. L-shaped sliding grooves are opened on both sides of the top of the inner cavity of the material feeding frame. The material feeding frame extends forward to the bottom of the tilting frame, and an auxiliary slide groove communicating with the L-shaped slide groove is provided inside the tilting frame. Side slide grooves for sliding of the material feeding frame are provided on the left and right sides of the material feeding frame. The tilting frame is rotatably inserted at the front end of the material feeding frame. L-shaped slide grooves are provided on both the left and right sides of the top of the inner cavity of the material feeding frame. The L-shaped slide groove extends forward to the bottom of the tilting frame, and an auxiliary slide groove communicating with the L-shaped slide groove is provided inside the tilting frame. A first rotating block is provided inside the material feeding frame on the side corresponding to the positioning hole. Outwardly penetrating discharge ports are provided on the left and right sides of the first rotating block. A positioning slider is slidably provided inside the first rotating block. Positioning plugs are integrally provided on both the left and right sides of the positioning slider.

[0006] Preferably, a side cavity is provided on one side of the bottom of the flaring device, and a rotating block is rotatably arranged inside the side cavity. A magnet is inserted into one end of the rotating block at the same height as the positioning connector.

[0007] As an advantage, the rear end of the feeding rack is provided with a slot, and the second box body is provided with a second storage cavity below the slot.

[0021] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] Example: A flaring device for mechanical parts, such as Figures 1-7As shown, it includes two first box bodies 11 and a second box body 12 connected from left to right. The surface of the first box body 11 is provided with a plurality of wear-resistant pads 15, which are used to flip the bottom of the first box body 11 to contact the ground when the hole is actually enlarged, thereby increasing the wear resistance and preventing the surface of the first box body 11 from being rubbed too much. The first box 11 and the second box 12 are connected by a single plastic assembly for easy flipping. The entire assembly is made of the same material as a tool box used in daily life. On the closed side of the first box 11 and the second box 12, there are a first cavity 18, a second cavity 19, and a third cavity 1110. The first cavity 18 houses a cutting device 5. The second cavity 19 houses a flaring device, which includes a slide 41 slidably mounted on a feeding rack 3. A sleeve 42 is located on the top of the slide 41, and a flaring rod 43 is threaded into the sleeve 42. Two levers are located on either side of the top of the flaring rod 43. The third cavity 1110 houses a flaring clamp 2, which includes two symmetrically arranged side clamps 21. The two side clamps 21 are rotatably connected to each other. One end of each side clamp 21 facing one side has a clamping cavity 24. The top of each side clamp 21 facing one side has multiple flared holes 22 of different sizes extending downwards. One side clamp 21 has multiple side positioning holes 23 corresponding to the flared holes 22. The side positioning holes 23 are equally arranged on one side of the flared holes 22, and the centers of the two are at the same intersection point. The top of the other end of each side clamp 21 is provided with an L-shaped slider 25. The first box 11 and the second box 12 are both provided with a fourth cavity 13 on the side away from each other. The top of the second box 12 is provided with a feeding rack 3 for installing the flaring device. The feeding rack 3 is provided with a discharge slot 31 for discharging the flaring device above the fourth cavity 13.

[0023] The sides of the fourth cavity 13 are respectively formed with gripping frames 14 corresponding to the first box 11 and the second box 12. A through groove 141 is opened in the middle of the gripping frame 14. The gripping frame 14 on the first box 11 is half the height of the first box 11, and the gripping frame 14 on the second box 12 is the same height as the second box 12, so that the fourth cavity 13 formed inside can accommodate the material rack 3. The fourth cavity 13 inside the second box 12 is provided with insertion receiving seats 17 on both sides. The corresponding top sides of the fourth cavity 13 are provided with pressing strips 16. The insertion receiving seats 17 insert and receive the material rack 3. After the bottom of the material rack 3 is locked by the insertion receiving seats 17 on both sides, the material rack 3 is limited after being inserted by the pressing strip 16 on the top and the buckle at the end. The buckle at one end of the pressing strip 16 is provided with the buckle head on the surface of the second box 12, thereby realizing the limitation of the pressing strip 16.

[0024] The left and right sides of the feeding rack 3 are provided with side sliding grooves 33 for the feeding rack 3 to slide. The front end of the feeding rack 3 is rotatably connected to a flipping frame 37. The left and right sides of the top of the inner cavity of the feeding rack 3 are provided with L-shaped sliding grooves 32. The L-shaped sliding grooves 32 extend forward to the bottom of the flipping frame 37. An auxiliary sliding groove 321 communicating with the L-shaped sliding grooves 32 is provided in the flipping frame 37. The feeding rack 3 is provided with a first rotating block 39 inside the side corresponding to the positioning hole 23. The left and right sides of the first rotating block 39 are provided with outwardly penetrating discharge ports 36. The positioning slider 35 is slidably arranged inside the first rotating block 39. The left and right sides of the positioning slider 35 are integrally provided with positioning connectors 351. The ends of the positioning connectors 351 are semi-circular.

[0025] A side cavity 38 is provided on one side of the bottom of the flaring device. A rotating block is rotatably arranged inside the side cavity 38. A magnet 310, which is set at the same height as the positioning connector 351, is inserted into one end of the rotating block.

[0026] The rear end of the feeding rack 3 is provided with a slot 311. The second box 12 is provided with a second storage cavity 312 below the slot 311. A second rotating block 313 is provided in the second storage cavity 312. A crossbar 314 that is inserted into the slot 311 is connected between the two second rotating blocks 313 on the left and right. When the crossbar 314 is flipped down, it is stored through the channel between the two storage cavities on the left and right to avoid protrusion.

[0027] The principle of this invention: When it is necessary to enlarge the copper tube, open the box and take out the flaring clamp 2, flaring tool and cutting device 5. Then close the box and place the second box 12 with one side facing up. Then, use the cutting device 5 to make a circumferential cut on the surface of the end of the copper tube that needs to be enlarged. Then, open the buckle of the pressure belt 16 and take out the feeding rack 3 located inside the fourth cavity 13. At the same time, flip the second rotating block 313 upward so that the crossbar connected to the two flips to the top of the second box 12. Then, insert the slot 311 at the rear end of the feeding rack 3 into the crossbar 314. The second rotating blocks 313 on both sides limit its left and right movement. The front end of the feeding rack 3 is placed on the top of the holding frame 14, which is at the same height as the second box 12.

[0028] At this point, as needed, the flaring clamp 2 can be inserted into the feeding rack 3 by moving it forward from the rear end of the feeding rack 3, and aligned with the flaring hole 22 corresponding to the discharge slot hole 31 at the top of the feeding rack 3. After alignment, the slide 41 at the bottom of the flaring device is inserted into the top of the feeding rack 3, and then slid to the front end of the side slide grooves 33 on both sides. The front end of the side slide grooves 33 moves forward and passes through the feeding rack 3, forming a baffle at the front end. This allows the slide 41 to slide to the front end, enabling the bottom of the flaring rod 43 to rotate downward through the discharge slot hole 31 at the bottom for flaring. At the same time, as the slide 41 moves forward, the slide 41 will press against the positioning connector 351 on one side of the positioning slider 35. Since the end of the positioning connector 351 is round, when the slide 41 continues to push forward, it will drive the positioning slider 35 to push to the other side, so that the positioning connector 351 at the other end slides out of the discharge port 36 and positions the side positioning hole 23 on one side of the flaring clamp 2, thus completing the positioning of the flaring clamp 2. Then, the copper tube that needs to be flared is inserted upward through the bottom of the fourth cavity 13 corresponding to the flaring hole 22. However, this method of insertion is relatively difficult.

[0029] Another method involves opening the flipping frame 37 at the front end of the feeding rack 3. Then, hold the two side clamps 21 and squeeze them tightly on both sides of the receiving cavity 24. Next, insert the copper tube that needs to be flared into the flared hole 22. The side clamps 21 will then hold the copper tube, with the top extending 1-2 mm above the bottom of the flaring clamp 2. Then, insert the L-shaped sliders 25 at the top of the two side clamps 21 into their corresponding grooves. The flipping frame 37 will then flip so that its internal L-shaped groove 32 connects with the groove on the feeding rack 3. The flaring clamp 2 will then be pushed inward along the L-shaped groove 32 so that the copper tube aligns with the discharge slot 31 at the top. Finally, push the flaring device into the feeding rack 3 so that the positioning connector 351 and the side positioning hole 23 are interlocked, completing the positioning.

[0030] Then, rotate the levers on both sides of the top of the flaring rod 43 to move downwards to flare the copper tube. Next, move the first rotating block 39 to disengage the magnet 310 at its front end from the side cavity 38. When the slide 41 moves backward, when the magnet 310 reaches the side of the positioning connector 351, it will magnetically attract the positioning connector 351 on the corresponding side, thereby disengaging the positioning connector 351 at the other end from the side positioning hole 23, causing the flaring clip 2 to lose its clamping, making it easy to remove the flaring clip 2 and replace the new copper tube.

[0031] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
