Description

Technical Field

[0001] This invention relates to the field of radiator processing equipment technology, and in particular to a stamping device for U-shaped radiator parts. Background Technology

[0002] A radiator is a device that transfers and dissipates excess heat generated by a heat-generating object (heat source) into the surrounding environment (usually air or liquid). Its core function is to control temperature and prevent equipment from degrading in performance, being damaged, or causing safety accidents due to overheating. It is a passive heat exchanger.

[0003] U-shaped parts are used in the assembly and use of radiators. Currently, U-shaped parts are manufactured using a stamping process. However, when producing U-shaped parts using a stamping process, the material is easily moved due to machine vibration during the stamping process, which makes it difficult for the opening angle and dimensional accuracy of the front U-shaped part to meet the design requirements, affecting subsequent assembly. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping device for U-shaped radiator parts, which addresses the problem that material movement during the stamping process of U-shaped parts is easily caused by machine vibration, resulting in difficulty in meeting design requirements for the opening angle and dimensional accuracy of the front U-shaped parts and affecting subsequent assembly.

[0005] To achieve the above objectives, the present invention provides a stamping device for U-shaped radiator parts, comprising: an upper die mechanism and a lower die mechanism. The upper die mechanism is provided with a first mounting groove, in which a clamping component and a punch are disposed. The punch is located in the middle of the clamping component. The lower die mechanism is provided with a forming cavity, in which a positioning component is disposed. The positioning component includes a mounting base, a positioning rib, and a magnetic suction component. The mounting base is built into the forming cavity and has a clearance through hole located directly below the punch. The mounting base is provided with a second mounting groove, in which an elastic element is disposed. One end of the elastic element is connected to the positioning rib, which is movably connected within the second mounting groove. The magnetic suction component is disposed on the mounting base and drives the positioning rib to move downward, the positioning rib being adapted to the positioning groove on the product.

[0006] As a further description of the above technical solution:

[0007] The magnetic attraction component includes an electromagnet and a neodymium iron boron magnet. The neodymium iron boron magnet is connected to the positioning rib, and the electromagnet is located below the neodymium iron boron magnet. The electromagnet is mounted on the mounting base.

[0008] As a further description of the above technical solution:

[0009] The positioning rib is fixed on the slider, the slider is slidably connected in the second mounting groove, and the neodymium iron boron magnet is installed in the slider.

[0010] As a further description of the above technical solution:

[0011] Two positioning ribs are provided, and the two positioning ribs are respectively located on both sides of the avoidance through hole.

[0012] As a further description of the above technical solution:

[0013] The elastic element is a spring or an elastic rubber block.

[0014] As a further description of the above technical solution:

[0015] The clamping component includes a clamping block and several springs. The several springs are evenly arranged in the first mounting groove. One end of each spring is connected to the clamping block, and the clamping block is slidably connected in the first mounting groove.

[0016] As a further description of the above technical solution:

[0017] The clamping block has a through hole in the middle, and the punch passes through the through hole to connect with the upper mold mechanism.

[0018] As a further description of the above technical solution:

[0019] The upper mold mechanism includes an upper mold base, an upper pad, an upper clamping plate, a stripping back plate, and a stripping plate arranged from top to bottom.

[0020] As a further description of the above technical solution:

[0021] The lower mold mechanism includes a lower template, a lower pad, a lower mold base, and a lower support plate arranged from top to bottom, with multiple lower pad feet provided between the lower mold base and the lower support plate.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, by setting up a mounting base, positioning ribs, and magnetic components, the positioning ribs are inserted into the positioning grooves on the product during stamping. This can restrict the movement of the product and increase the resistance of the sheet metal flowing into the die, causing the product to undergo greater plastic tensile deformation during the forming process, thereby reducing the proportion of elastic strain and suppressing springback. After stamping is completed, the electromagnet is energized, thereby attracting the neodymium iron boron magnet, which in turn causes the positioning ribs to move downwards, separating the positioning ribs from the positioning grooves, thus facilitating material removal.

[0024] 2. In this invention, by setting a clamping block and a spring, when stamping begins, the clamping block first presses down on the product. As the upper die mechanism moves downward, the spring is compressed, the clamping block enters the first mounting groove, and the punch starts to work. This makes it difficult for the product to move during the stamping process, thus improving the quality of the stamping. Attached Figure Description

[0038] Example 1:

[0039] Please see Figures 1-5This invention provides a stamping device for U-shaped radiator parts, comprising: an upper die mechanism 1 and a lower die mechanism 2. The upper die mechanism 1 is provided with a first mounting groove 3, and a clamping component 4 and a punch 5 are disposed within the first mounting groove 3. The punch 5 is located in the middle of the clamping component 4. The lower die mechanism 2 is provided with a forming cavity 6, and a positioning component 7 is disposed within the forming cavity 6. The positioning component 7 includes a mounting base 71, a positioning rib 72, and a magnetic suction component 73. The mounting base 71 is built into the forming cavity 6. The mounting base 71 is provided with a clearance through hole 8, which is located directly below the punch 5. The mounting base 71 is provided with a second mounting groove 9, and an elastic element 10 is provided in the second mounting groove 9. One end of the elastic element 10 is connected to the positioning rib 72, and the positioning rib 72 is movably connected in the second mounting groove 9. The magnetic suction component 73 is provided on the mounting base 71, and the magnetic suction component 73 drives the positioning rib 72 to move downward. The positioning rib 72 is adapted to the positioning groove 12 on the product 11.

[0040] Specifically, two positioning ribs 72 are provided, and the two positioning ribs 72 are respectively located on both sides of the clearance through hole 8. This can make the product more stable and prevent it from moving to one side during the stamping process.

[0041] Specifically, the elastic element 10 is a spring or an elastic rubber block. The elastic element is a spring.

[0042] Specifically, the clamping block 42 has a through hole in the middle, and the punch 5 passes through the through hole and connects to the upper mold mechanism 1.

[0043] Specifically, the upper mold mechanism 1 includes an upper mold base 14, an upper pad 15, an upper clamping plate 16, a stripping back plate 17, and a stripping plate 18 arranged from top to bottom.

[0044] Specifically, the lower mold mechanism 2 includes a lower template 21, a lower pad 22, a lower mold base 23, and a lower support plate 24 arranged from top to bottom, and a plurality of lower pad feet 25 are provided between the lower mold base 23 and the lower support plate 24.

[0045] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0046] 1. In this invention, by setting up a mounting base, positioning ribs, and magnetic components, the positioning ribs are inserted into the positioning grooves on the product during stamping. This can restrict the movement of the product and increase the resistance of the sheet metal flowing into the die, causing the product to undergo greater plastic tensile deformation during the forming process, thereby reducing the proportion of elastic strain and suppressing springback. After stamping is completed, the electromagnet is energized, thereby attracting the neodymium iron boron magnet, which in turn causes the positioning ribs to move downwards, separating the positioning ribs from the positioning grooves, thus facilitating material removal.

[0047] 2. In this invention, by setting a clamping block and a spring, when stamping begins, the clamping block first presses down on the product. As the upper die mechanism moves downward, the spring is compressed, the clamping block enters the first mounting groove, and the punch starts to work. This makes it difficult for the product to move during the stamping process, thus improving the quality of the stamping.

[0048] Example 2:

[0049] See Figures 1-5 The figure shows a stamping device for a U-shaped radiator part provided by Embodiment 2 of the present invention. This embodiment further improves upon the previous embodiment by making the following technical improvements: The magnetic attraction component 73 includes an electromagnet 731 and a neodymium iron boron magnet 732. The neodymium iron boron magnet 732 is connected to the positioning rib 72, and the electromagnet 731 is located below the neodymium iron boron magnet 732 and is mounted on the mounting base 71. After stamping, the electromagnet is energized, thereby attracting the neodymium iron boron magnet, which in turn moves the positioning rib downwards, separating the positioning rib from the positioning groove to facilitate unloading. After unloading, the electromagnet is de-energized, and under the action of the elastic element, the positioning rib resets, facilitating the stamping of the next product.

[0050] Example 3:

[0051] See Figures 1-5 The figure shows a stamping device for a U-shaped radiator part provided by Embodiment 3 of the present invention. This embodiment further improves upon the above embodiments by making the following technical improvements: the positioning rib 72 is fixed on the slider 13, the slider 13 is slidably connected in the second mounting groove 9, and the neodymium iron boron magnet 732 is installed in the slider 13. The slider facilitates the up-and-down movement of the positioning rib and also facilitates the installation of the neodymium iron boron magnet.

[0052] Example 4:

[0053] See Figures 1-5 The figure shows a stamping device for a U-shaped radiator part provided by Embodiment 4 of the present invention. This embodiment further improves upon the previous embodiments by making the following technical solution: The clamping component 4 includes a clamping block 41 and several springs 42. The springs 42 are evenly arranged in the first mounting groove 3. One end of each spring 42 is connected to the clamping block 41, and the clamping block 41 is slidably connected in the first mounting groove 3. At the start of stamping, the clamping block first presses down on the product. As the upper die mechanism descends, the springs compress, the clamping block enters the first mounting groove, and the punch begins to work. This makes the product less prone to movement during stamping, improving the quality of the stamped product.

[0054] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
