Description

Technical Field

[0001] This invention relates to the field of bicycle manufacturing equipment, and more specifically to a tube molding device. Background Technology

[0002] Bicycle frames require the welding of various tubing during production, some of which needs to be pressed into an elliptical shape to meet the frame's aesthetic requirements. Currently, after pressing, the tubing fits tightly to the mold, making it difficult to remove. Existing technology uses a metal rod inserted into the tubing to pry it open. This method is time-consuming and labor-intensive, and the force applied while prying is difficult to control, easily causing deformation at the tubing's end and affecting the manufacturing quality. Therefore, effectively removing the tubing from the mold remains a pressing technical problem.

[0003] In summary, the technical problem that this application needs to solve is how to quickly and efficiently disassemble the pipe fittings from the mold. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a pipe molding device. Under the action of a clamping mechanism, the mold completes a mold-closing action, extruding the pipe into a shape that fits into the mold groove. When the mold is separated, the pipe, already deformed and adhered to the mold groove, is difficult to remove. This solution employs a combination of a position adjustment component and a pushing component for pipe disassembly. The position adjustment component adjusts the position of the pushing component, placing it in a suitable position, while the moving platform on the position adjustment component remains stationary. The pushing rod on the pushing component pushes the pipe, thereby detaching it from the mold groove and improving the pipe disassembly efficiency.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] like Figures 1 to 5 As shown, this embodiment proposes a pipe fitting molding device, including:

[0033] Frame 11, on which a clamping mechanism 12 is mounted;

[0034] The mold assembly is mounted on the frame 11. The clamping mechanism 12 is used to clamp the mold assembly. The mold assembly has mold grooves 43 through both ends for installing pipe fittings.

[0035] The pushing assembly 13 has a pushing rod 14, the direction of movement of the pushing rod 14 is consistent with the length direction of the tube, and the pushing rod 14 is used to insert into the mold groove 43 and push the tube.

[0036] The position adjustment assembly has a moving platform 15 for mounting the pushing assembly 13.

[0037] In this design, the mold closes under the action of the clamping mechanism 12, which is used to compress the pipe into the shape of the mold groove 43. When the mold is separated, the pipe is difficult to remove because it has already deformed and is attached to the mold groove 43. This design uses a combination of a position adjustment component and a pushing component to disassemble the pipe.

[0038] The position adjustment component is used to adjust the position of the pushing component 13 so that it is in a suitable working position, and then the moving platform 15 on the position adjustment component will remain stationary. The pushing rod 14 on the pushing component 13 pushes the pipe, thereby disengaging the pipe from the mold slot 43, thus improving the disassembly efficiency of the pipe.

[0039] As one embodiment of this example, the frame 11 includes a base plate 16, a first frame 17, a second frame 18, and a mounting base. The first frame 17 and the second frame 18 are fixed on the base plate 16, and the mounting base is fixed on the second frame 18. The mounting base is used to install the clamping mechanism 12, and the mold assembly is installed on the first frame 17.

[0040] In one embodiment of this invention, the height of the second frame 18 is greater than the height of the first frame 17.

[0041] As one embodiment of this invention, the position adjustment assembly includes a first fixed plate 20, a first slide rail 21, a lead screw and slider mechanism 22, and a first motor 19. The first fixed plate 20 is fixed on the base plate 16. The moving platform 15 is slidably mounted on the first fixed plate 20 via the first slide rail 21. The first motor 19 is mounted on the first fixed plate 20 and is connected to the moving platform 15 via the lead screw and slider mechanism 22.

[0042] The lead screw and slider mechanism 22, which is driven by the second motor 37, is one of the more common linear motion mechanisms and belongs to the prior art. The specific structure of the lead screw and slider will not be described in detail in this solution.

[0043] The working principle of this embodiment is as follows: the first motor 19 drives the lead screw and slider mechanism 22 to work, and the first motor 19 drives the moving platform 15 to move through the lead screw and slider mechanism 22. The moving platform 15 moves linearly under the guidance of the first slide rail 21.

[0044] As one embodiment of this invention, the pushing assembly 13 includes a second fixed plate 24, a third fixed plate 25, a second slide rail 26, a moving assembly 27, a cam mechanism 28, and a reset mechanism 29. The second fixed plate 24 is fixed to the moving platform 15 by a third frame, and the third fixed plate 25 is fixed on the second fixed plate 24. The third fixed plate 25 is provided with the second slide rail 26. The moving assembly 27 is slidably mounted on the second slide rail 26. A pushing rod 14 is mounted on the moving assembly 27. The cam mechanism 28 is mounted on the third fixed plate 25 and is used to squeeze the moving assembly 27. The end of the second fixed plate 24 is provided with a fixed arm 30, and the fixed arm 30 is connected to the moving assembly 27 through the reset mechanism 29.

[0045] This design employs a cam mechanism 28 to compress the moving component 27, thereby driving the moving component 27 to move. The moving component 27 reciprocates under the action of the reset mechanism 29, facilitating the pushing rod 14 to push the pipe and then retract it. The advantage of using the cam mechanism 28 is that the stroke of the pushing rod 14 is short; it only needs to push the pipe in the mold groove 43 to loosen it, reducing the pipe's travel in the mold groove 43 and thus reducing surface damage caused by friction.

[0046] As one embodiment of this invention, the moving component 27 includes a moving block 31, a connecting rod 32, a first elastic element 33, and a push block 34. The moving block 31 is slidably mounted on the second slide rail 26. One end of the moving block 31 is connected to the push block 34 through the first elastic element 33. A pushing rod 14 is fixed on the push block 34. The other end of the moving block 31 is fixed with a connecting rod 32, which is used to connect to the reset mechanism 29.

[0047] The technical effect of this solution is that: the pusher 34 is fixed with a pusher rod 14, and the pusher 34 is mounted on the moving block 31 through the first elastic element 33. Therefore, when the pusher rod pushes the pipe fitting, it pushes flexibly. As the deformation of the first elastic element 33 increases, the pushing force of the pusher rod will gradually increase. Therefore, the pushing force of the pusher rod on the pipe fitting will not be very large, thereby effectively preventing the pushed end of the pipe fitting from deforming and effectively protecting the appearance shape of the pipe fitting.

[0048] The first elastic element 33 can be directly a first spring, or it can be connected between the push block 34 and the moving block 31 through a telescopic slide rod, with the first spring sleeved on the telescopic slide rod. Of course, the first elastic element 33 in this solution can also adopt other existing technologies.

[0049] As one embodiment of this invention, the moving component 27 further includes a positioning block 35, and the number of connecting rods 32 is multiple. The positioning block 35 is provided with multiple mounting holes for mounting the connecting rods 32.

[0050] In one embodiment of this invention, the reset mechanism 29 is a second elastic element. The second elastic element is a second spring.

[0051] In one embodiment of this invention, the cam mechanism 28 includes a cam portion 36 and a second motor 37. The cam portion 36 is rotatably mounted on a third fixed plate 25, and the second motor 37 is mounted on the lower surface of a second fixed plate 24. The shaft of the second motor 37 passes through the second fixed plate 24 and the third fixed plate 25 and is connected to the cam portion 36. The second fixed plate 24 and the third fixed plate 25 are provided with clearance holes for the shaft of the second motor 37 to pass through.

[0052] As one embodiment of this invention, the mold assembly includes a lower mold 38, an upper mold 39, a top plate 40, a guide rod 41, and a third spring 42. The lower mold 38 is fixed on the first frame 17, the top plate 40 is fixed above the lower mold 38 by the guide rod 41, the upper mold 39 is located below the top plate 40, and the upper mold 39 is provided with a plurality of through holes for sliding through the guide rod 41. The third spring 42 is provided between the upper mold 39 and the lower mold 38.

[0053] As one embodiment of this invention, the upper end face of the lower mold 38 is provided with a first curved groove, the lower end face of the upper mold 39 is provided with a second curved groove, and the model groove 43 is composed of the first curved groove and the second curved groove.

[0054] In one embodiment of this invention, a guide block 44 is fixed to one side of the lower mold 38 opposite to the pushing assembly 13. The guide block 44 has an inclined surface 45 for guiding the movement of the tube. When the tube is removed from the mold slot 43, the tube moves along the direction of the inclined surface 45, thereby lifting one end of the tube and making it easier to remove.

[0055] The pressing mechanism 12 includes a telescopic member 47 and a pressing block 46. The telescopic member 47 has an output end that moves in the vertical direction. The telescopic member 47 is fixed on the frame 11, and the pressing block 46 is fixed on the output end of the telescopic member 47. An extrusion rod 23 is fixed on the lower surface of the pressing block 46. The extrusion rod 23 is slidably inserted into the through hole of the top plate 40. The extrusion rod 23 is used to extrude the upper mold 39.

[0056] The telescopic component 47 is a cylinder or hydraulic cylinder. When the telescopic component 47 is extended downwards, it pushes the pressing block 46 downwards. The pushing rod 14 at the lower end of the pressing block 46 passes through the through hole of the top plate 40 and presses the upper mold 39. At this time, the positions of the top plate 40 and the lower mold 38 are not aligned. The upper mold 39 moves downwards and extrudes the pipe on the lower mold 38. Finally, the telescopic component 47 drives the pressing block 46 to move upwards by 1 to 2 centimeters. At this time, the upper mold 39 also moves upwards by a corresponding distance, separating the upper mold 39 and the lower mold 38. Since the pipe may be adsorbed in the upper mold 39 or the lower mold 38, by making the distance between the upper mold 39 and the lower mold 38 very small, it is easy for the pushing rod 14 to effectively push the pipe.

[0057] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
