Description

Technical Field

[0001] This utility model relates to the field of hot bending processing technology, and in particular to a hot bending machine for hollow rubber hoses. Background Technology

[0002] Plastic pipes are a general term for pipes made of plastic. Compared with traditional cast iron pipes, galvanized pipes, cement pipes, etc., plastic pipes have advantages such as energy saving, material saving, environmental protection, lightweight and high strength, corrosion resistance, smooth inner wall without scaling, simple construction and maintenance, and long service life. Plastic pipes are widely used in various fields of daily life. In actual use, plastic pipes need to be heat-bent through hot bending, which is the process of heating the pipe to the specified bending temperature and then bending the pipe.

[0003] In existing hot bending processes for rubber hoses, the hose is typically fed manually into a heating device for heating, and then bent at a specific angle using a bending device. Because manual feeding makes it impossible to precisely control the heating time, it's difficult to ensure the hose is heated to the appropriate temperature. This is especially problematic for hollow hoses; excessive heating can cause internal blockage during bending, while insufficient heating can lead to breakage, thus affecting the quality of the hot bending process. Therefore, it is necessary to research a new technical solution to address these issues. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a hollow hose hot bending machine that can effectively solve the problems of uncontrollable heating time and temperature and unguaranteed hot bending quality in the existing hose hot bending process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hollow rubber hose hot bending machine includes a base frame, a mold base, a feeding seat, a first drive mechanism, a baking mold, a second drive mechanism, a forming seat, and a third drive mechanism.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] The feeding seat can be movably mounted on the base frame and located above the mold base; the baking mold can be movably mounted on the base frame and located beside the mold base, facing the feeding seat, so that the product on the feeding seat is automatically fed into the baking mold for heating.

[0034] Please refer to Figures 1 to 4As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a base frame 10, a mold base 20, a feeding seat 30, a first driving mechanism 40, a baking mold 50, a second driving mechanism 60, a forming seat 70, and a third driving mechanism 80.

[0035] The mold base 20 is mounted on the base frame 10, and the mold base 20 has a material groove 201 that matches the bending shape of the product. The material groove 201 can be designed with different corresponding shapes according to the different shapes of the products to be bent, and its shape is not limited. In this embodiment, a machine cover 11 is provided on the base frame 10, and the baking mold 50 is covered by the machine cover 11. Heat dissipation holes 101 are provided on both side walls of the machine cover 11, and a cooling fan 12 is provided on the top of the machine cover 11. This machine cover 11 not only prevents the baking mold 50 from being affected by external factors during operation, but also protects the user from accidental burns from the baking mold. The heat dissipation holes 101 and the cooling fan 12 are used to dissipate excess heat inside the machine cover 11, preventing heat accumulation. Multiple material grooves 201 are arranged horizontally at intervals.

[0036] The feeding seat 30 is movably mounted on the base frame 10 and located above and to the side of the mold base 20. The feeding seat 30 has a mounting groove 301 that mates with the product. The first drive mechanism 40 is mounted on the base frame 10 and drives the feeding seat 30 to move back and forth. The external product to be processed is mounted in the feeding groove 30 through the mounting groove 301. In this embodiment, a baffle 13 is provided on the base frame 10. The baffle 13 is located outside the feeding seat 30 and is detachably mounted on the base frame 10. The baffle 13 is used to prevent the user from accidentally putting their hand inside during processing, thus providing protection.

[0037] The baking mold 50 is movably mounted on the base frame 10 and located beside the mold base 20, facing the feeding seat 30. The side wall of the baking mold 50 facing the feeding seat 30 has a recessed heating groove 501 that mates with the product. The second drive mechanism 60 is mounted on the base frame 10 and drives the baking mold 50 to move back and forth. As the baking mold 50 moves towards the feeding seat 30, a portion of the product to be processed in the mounting groove 301 extends into the heating groove 501, thereby heating the product. In this embodiment, the mounting groove 301 and the heating groove 501 are arranged horizontally at intervals, allowing for the simultaneous completion of the hot bending process for multiple products. Furthermore, the material groove 201, mounting groove 301, and heating groove 501 are all arranged in intervals of 10. Similarly, the number can be any other number set according to actual production needs, without limitation. The baking mold 50 includes a mounting bracket 51 and a heating head 52; the mounting bracket 51 is mounted on the base frame 10 and located next to the mold base 20; the heating groove 501 is formed in the heating head 52; the second driving mechanism 60 is mounted on the mounting bracket 51 and drives the heating head 52 to move back and forth.

[0038] The forming seat 70 is movably mounted on the base frame 10 and located directly above the mold base 20. The third drive mechanism 80 is mounted on the base frame 10 and drives the forming seat 70 to move back and forth. The forming seat 70 presses down to bend the heated product on the mold base 20. In this embodiment, the forming seat 70 includes a mounting plate 71, a forming plate 72, a positioning plate 73, and a spring 74. The mounting plate 71 is movably mounted on the base frame 10. The forming plate 72 is located at the bottom of the mounting plate 71, and the lower end of the forming plate 72 has a bending groove 701 that mates with the bent portion of the product. The positioning plate 73 is movably mounted on the mounting plate 71 and moves back and forth with the mounting plate 71. The positioning plate 73 is located below the front side of the forming plate 72, and the lower end of the positioning plate 73 has a positioning groove 702 that mates with the product. The spring 74 clamps... A positioning plate 73 is positioned between the positioning plate 73 and the mounting plate 71, causing the positioning plate 73 to move downwards and reset. When the mounting plate 71 moves downwards, the positioning plate 73 located below will first contact the product in the material trough 201 and position it. Then, the mounting plate 71 continues to move downwards, at which time the spring 74 is compressed until the forming plate 72 continues to move downwards and contacts the product, completing the bending process. Finally, the mounting plate 71 moves upwards, and the spring 74 causes the positioning plate 73 to move downwards and reset. This ensures that the positioning plate 73 is used for positioning during bending, further guaranteeing the bending accuracy and the overall quality of the hot bending process.

[0039] Furthermore, it also includes a positioning component 90, which includes a positioning plate 91 and a fourth drive mechanism 92. The positioning plate 91 is movably mounted on the base frame 10 toward the mold base 20 and corresponds to the position of the material groove 201 in the mold base 20. The fourth drive mechanism 92 is mounted on the base frame 10 and drives the positioning plate 91 to move back and forth. When bending is performed, when the feeding seat 30 moves the product into the material groove 201, the positioning plate 91 moves toward the material groove 201 to position the product in the material groove 201, thereby ensuring the accuracy of subsequent bending processing.

[0040] The working process of this embodiment is described in detail below:

[0041] During operation, the entire equipment is first connected to an external power supply and controller. Then, the product to be processed is manually loaded into the mounting slot 301. Next, the second drive mechanism 60 drives the baking mold 50 to move toward the feeding seat 30, so that the outer end of the product enters the heating tank 501. The heating head 52 completes the heating process of the bent part of the product. After heating is completed, the second drive mechanism 60 drives the baking mold 50 to reset. Then, the first drive mechanism 40 drives the feeding seat 30 to move downward, so that the product enters the material tank 201. Then, the positioning plate 91 moves toward the feeding seat 30 and positions the product in the material tank 201 in the front and back directions. After positioning, the third drive mechanism 80 drives the mounting plate 71 to move downwards. During this movement, the lower positioning plate 73 first contacts and positions the product in the material trough 201. Then, the mounting plate 71 continues to move downwards, at which point the spring 74 is compressed until the forming plate 72 continues to move downwards and contacts the product, completing the bending process. Finally, the mounting plate 71 moves upwards, and the spring 74 causes the positioning plate 73 to move downwards and reset. Then, the first drive mechanism 40 drives the feeding seat 30 to reset upwards. After the product cools down, the hot-bent product can be removed manually.

[0042] The key design features of this invention are: a feeding seat that can be movably mounted on the base frame and positioned above the mold base; and a baking mold that can be movably mounted on the base frame and positioned beside the mold base, allowing for automated feeding of the product from the feeding seat into the baking mold for heating. This facilitates control of heating time and temperature, preventing overheating that could clog the hollow tube or underheating that could cause breakage during bending, thus ensuring the quality of the hot bending process. Furthermore, a forming seat that can be movably mounted on the base frame and positioned directly above the mold base allows the bending process after heating to be completed by the downward pressure of the forming seat, thereby completing the overall hot bending process.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
