Description

Technical Field

[0001] This invention relates to the field of sheet metal stamping die technology, specifically to a sheet metal stamping die for a washing machine. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping molds). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation to obtain the desired parts. Stamping is a manufacturing process that processes raw materials into the required shapes through cutting, bending, stretching, and pressing within stamping dies. Stamping dies are crucial tools supporting stamping processes, determining processing quality and production efficiency. The main function of stamping dies is to process raw materials into the required shapes and sizes. Stamping dies can cut raw materials into the desired shapes, creating the prototypes of the desired products. Through processes such as stretching, the strength of the raw materials can be increased, making them more durable. Using stamping dies can significantly optimize the production process, reduce production costs, and improve production efficiency.

[0003] However, existing sheet metal stamping dies for washing machines suffer from low production efficiency and difficulty in mass production when stamping the cylindrical part of the washing machine. This affects production efficiency, reduces the efficiency and capacity of the production line, and increases production costs. Furthermore, after stamping the cylindrical part of the washing machine, the circular sheet metal tends to tightly wrap around the cylindrical side wall of the stamping head, making it difficult to unload.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1-14 As shown, the sheet metal stamping die for a washing machine according to the present invention includes a pushing mechanism 1, a feeding mechanism 2, a pressing mechanism 3, a clamping mechanism 4, and an unloading mechanism 5.

Then, the second sliding blocks 49 on both sides of the second fixed block 47 move inward, driving the U-shaped sheet metal 18 to be pressed into a circle. The first arc block 38 is designed with a diameter that can be increased and decreased to facilitate unloading. During stamping, the diameter of the first arc block 38 increases, and when the first arc block 38 retracts, the diameter decreases.

[0038] Preferably, the pushing mechanism 1 includes a first base plate 11, a support plate 12 fixedly connected to the upper end of the first base plate 11, a second base plate 13 fixedly connected to the upper end of the support plate 12, a first guide rail 14 fixedly connected to the upper end of the second base plate 13, a side plate 15 fixedly connected to the upper end of the second base plate 13, a fixing plate 16 connected to one side wall of the side plate 15, a first sliding plate 17 slidably connected to the inner side wall of the side plate 15, a plate 18 tightly fitted to one end of the first sliding plate 17, a first spring 19 fixedly connected to the side wall of the side plate 15, a support rod 110 fixedly connected to one end of the first spring 19, and the support rod 110...

A first opening 112 is opened inside the first base plate 11, a second opening 113 is opened inside the first base plate 11, and a third opening 114 is opened inside the second base plate 13. First, the plate 18 is placed between the two side plates 15. A first spring 19 drives a support rod 110 to move inward. The inward movement of the support rod 110 drives the first sliding rod 111 to move inward, which in turn drives the first sliding plate 17 to move inward. This structure automatically pushes the plate 18 to the frontmost edge of the two side plates 15, facilitating subsequent loading of the plate 18.

[0039] Preferably, the feeding mechanism 2 includes a hydraulic cylinder 21, the side wall of which is fixedly connected to the first base plate 11. A first connecting rod 22 is fixedly connected to the upper end of the hydraulic cylinder 21. A first inclined slider 23 is fixedly connected to one end of the first connecting rod 22. A second connecting rod 24 is fixedly connected to the upper end of the first inclined slider 23. A second inclined slider is fixedly connected to the side wall of the second connecting rod 24.

A second guide rail 28 is slidably connected to the side wall of the second sliding rod 27. The lower end of the second guide rail 28 is fixedly connected to the first base plate 11. A push plate 29 is fixedly connected to one end of the second sliding rod 27. A support block 210 is fixedly connected to the inner side wall of the second guide rail 28.

A compression spring 212 is fixedly connected to one end of the stop block 211. One end of the compression spring 212 is fixedly connected to the support block 210. Then; at this time, the hydraulic cylinder 21 is activated to move upward. The upward movement of the hydraulic cylinder 21 will drive the first connecting rod 22 to move upward. The upward movement of the first connecting rod 22 will drive the first inclined slider 23 to move upward. The upward movement of the first inclined slider 23 will drive the second connecting rod 24 to move upward. The upward movement of the second connecting rod 24 will drive the second inclined slider to move upward. The upward movement of the second inclined slider will drive the third inclined slider 26 to move to one end. The movement of the third inclined slider 26 to one end will drive the second sliding rod 27 to move to one end. Moving the lever 27 to one end will cause the stop block 211 to move to one end. Moving the stop block 211 to one end will compress the compression spring 212. Moving the second sliding lever 27 to one end will cause the push plate 29 to move to one end. Moving the push plate 29 to one end will cause the plate 18 in the first guide rail 14 to slide to the upper end of the third opening 114. When the plate 18 slides to the upper end of the third opening 114, it will fall from the third opening 114 into the limiting plate 411. The structure can automatically push the plate 18 into the limiting plate 411, which is convenient and quick.

[0040] Preferably, the pressing mechanism 3 includes a fourth inclined slider 31, the upper end of which is attached to a first inclined slider 23. A sleeve 32 is fixedly connected to the side wall of the fourth inclined slider 31. A third sliding rod 33 is slidably connected to the inner side wall of the sleeve 32. A baffle 34 is fixedly connected to one end of the third sliding rod 33. A second spring 35 is fixedly connected to one end of the baffle 34. One end of the second spring 35 is fixedly connected to the sleeve 32. A round rod 36 is fixedly connected to one end of the third sliding rod 33. A first connecting block 37 is fixedly connected to the side wall of the round rod 36. A first arc-shaped block 38 is fixedly connected to one end of the first connecting block 37. A hollow groove 39 is formed on the outer side wall of the first arc-shaped block 38. A second sliding plate 310 is fixed to the lower end of the fourth inclined slider 31. A third guide rail 311 is slidably connected to the outer side wall of the second sliding plate 310. One end of 311 is fixedly connected to a circular block 312, the lower end of which is fixedly connected to the first base plate 11. During the downward movement of the first inclined slider 23, the fourth inclined slider 31 will be driven to move outward in the horizontal direction. The outward movement of the fourth inclined slider 31 will drive the sleeve 32 to move outward. The outward movement of the sleeve 32 will drive the third sliding rod 33 to move outward. The outward movement of the third sliding rod 33 will drive the circular rod 36 to move outward. The outward movement of the circular rod 36 will drive the first arc block 38 to move outward. The first arc block 38 is made of spring steel and has good bending ability. This allows the diameter of the first arc block 38 to be adjusted under compression. The outward movement of the first arc block 38 will first press the plate 18 into a U-shape. The structure can simultaneously drive the first arc block 38 to move outward during the downward movement of the first inclined slider 23, pressing the plate 18 into a U-shape.

[0041] Preferably, the clamping mechanism 4 includes a second connecting block 41, the upper end of which is fixedly connected to the second sliding plate 310. A fifth inclined slider 42 is fixedly connected to one end of the second connecting block 41. A sixth inclined slider 43 is attached to the upper end of the first base plate 11. A first sliding block 44 is fixedly connected to the upper end of the sixth inclined slider 43. A first fixing block 45 is fixedly connected to the side wall of the support plate 12. A sliding groove 46 is provided inside the first fixing block 45. The inner side wall of the sliding groove 46 is slidably connected to the first sliding block 44. A second fixing block 47 is fixedly connected to the upper end of the first fixing block 45. A first arc-shaped groove 48 is provided on the side wall of the second fixing block 47. A second sliding block 49 is fixedly connected to the upper end of the first sliding block 44. A second arc-shaped groove 48 is provided on the side wall of the second sliding block 49. The arc-shaped groove 410, the side wall of the second sliding block 49 is attached to the second fixed block 47, and the side wall of the second sliding block 49 is fixedly connected to the limit plate 411; when the fourth inclined slider 31 moves to one end, it will drive the fifth inclined slider 42 to move to one end, the fifth inclined slider 42 moving to one end will drive the sixth inclined slider 43 to move to one end, the sixth inclined slider 43 moving to one end will drive the first sliding block 44 to move inward, the first sliding block 44 moving inward will drive the second sliding block 49 to move inward, and the second sliding blocks 49 on both sides of the second fixed block 47 moving inward will drive the U-shaped plate 18 to be pressed into a circle. Through the set structure, during the downward movement of the first inclined slider 23, the second sliding blocks 49 on both sides of the second fixed block 47 can be driven to move inward, which will drive the U-shaped plate 18 to be pressed into a circle.

[0042] Preferably, the unloading mechanism 5 includes a third spring 51, one end of which is fixedly connected to the round rod 36, and one end of which is fixedly connected to a second arc-shaped block 52. One end of the second arc-shaped block 52 is fixedly connected to a third sliding block 53, and one end of the third sliding block 53 is fixedly connected to an arc-shaped plate 54. When the first arc-shaped block 38 fits into the first arc-shaped groove 48, the arc-shaped plate 54 is compressed and moves inward into the first arc-shaped block 38. This compression causes the third sliding block 53 to move inward, which in turn causes the second arc-shaped block 52 to move inward. The inward movement of the second arc-shaped block 52 compresses the third spring 51. The inward movement of the second arc-shaped block 52 expands the diameter of the first arc-shaped block 38, and the inward movement of the arc-shaped plate 54 coincides with the hollow groove 39. The arc-shaped plate 54 is located above the first arc-shaped block 38. When the shaped block 38 approaches the first arc groove 48 to press the plate 18, the arc plate 54 does not contact the plate 18, but directly contacts the first arc groove 48. The first arc block 38 at its lower end contacts the plate 18 and presses it into shape. When the first arc block 38 moves away from the first arc groove 48, the third spring 51 will reset. The reset of the third spring 51 will drive the second arc block 52 to move outward. The outward movement of the second arc block 52 will drive the third sliding block 53 to move outward. The outward movement of the third sliding block 53 will drive the arc plate 54 to move outward. At this time, the overall diameter of the first arc block 38 is reduced, which is convenient for unloading. The first arc block 38 is designed with a diameter that can be increased and decreased, which facilitates unloading. During stamping, the diameter of the first arc block 38 increases, and when the first arc block 38 retracts, the diameter decreases, which makes it convenient for the stamped circular plate 18 to fall from its side and exit the mold through the first opening 112.

[0043] Working principle: In use, the sheet material 18 is first placed between the two side plates 15. The first spring 19 drives the support rod 110 to move inward. The inward movement of the support rod 110 drives the first sliding rod 111 to move inward. The inward movement of the first sliding rod 111 drives the first sliding plate 17 to move inward. Through the designed structure, the sheet material 18 can be automatically pushed to the front end of the two side plates 15, facilitating the subsequent loading of the sheet material 18.

[0044] At this time, the hydraulic cylinder 21 is activated to move upward. The upward movement of the hydraulic cylinder 21 will cause the first connecting rod 22 to move upward, which in turn will cause the first inclined slider 23 to move upward. The upward movement of the first inclined slider 23 will then cause the second connecting rod 24 to move upward, which in turn will cause the second inclined slider to move upward. The upward movement of the second inclined slider will then cause the third inclined slider 26 to move to one end. The movement of the third inclined slider 26 to one end will then cause the second sliding rod 27 to move to one end. Moving rod 27 to one end will cause stop block 211 to move to one end. Moving stop block 211 to one end will compress spring 212. Moving the second sliding rod 27 to one end will cause push plate 29 to move to one end. Moving push plate 29 to one end will cause plate 18 in the first guide rail 14 to slide to the upper end of the third opening 114. When plate 18 slides to the upper end of the third opening 114, it will fall from the third opening 114 into the limiting plate 411. The structure can automatically push plate 18 into the limiting plate 411 conveniently and quickly.

[0045] During the downward movement of the first inclined slider 23, the fourth inclined slider 31 will move outward in the horizontal direction. The outward movement of the fourth inclined slider 31 will drive the sleeve 32 to move outward. The outward movement of the sleeve 32 will drive the third sliding rod 33 to move outward. The outward movement of the third sliding rod 33 will drive the round rod 36 to move outward. The outward movement of the round rod 36 will drive the first arc block 38 to move outward. The first arc block 38 is made of spring steel and has good bending ability. This allows the diameter of the first arc block 38 to be adjusted under compression. The outward movement of the first arc block 38 will first press the sheet 18 into a U-shape. The structure can simultaneously drive the first arc block 38 to move outward during the downward movement of the first inclined slider 23 to press the sheet 18 into a U-shape. Furthermore, by having four first arc blocks 38 stamping simultaneously, production efficiency can be improved and rapid mass production can be achieved.

[0046] When the fourth inclined slider 31 moves to one end, it will drive the fifth inclined slider 42 to move to one end. The fifth inclined slider 42 moving to one end will drive the sixth inclined slider 43 to move to one end. The sixth inclined slider 43 moving to one end will drive the first sliding block 44 to move inward. The first sliding block 44 moving inward will drive the second sliding block 49 to move inward. The second sliding blocks 49 on both sides of the second fixed block 47 moving inward will drive the U-shaped plate 18 to be pressed into a circle. Through the structure set, during the downward movement of the first inclined slider 23, the second sliding blocks 49 on both sides of the second fixed block 47 can be driven to move inward, thereby driving the U-shaped plate 18 to be pressed into a circle.

[0047] When the first arc-shaped block 38 fits into the first arc-shaped groove 48, the arc-shaped plate 54 is compressed and moves inward into the first arc-shaped block 38. This compression and inward movement of the arc-shaped plate 54 causes the third sliding block 53 to move inward. The inward movement of the third sliding block 53 causes the second arc-shaped block 52 to move inward. The inward movement of the second arc-shaped block 52 compresses the third spring 51. As the second arc-shaped block 52 moves inward, it expands the diameter of the first arc-shaped block 38. The inward movement of the arc-shaped plate 54 coincides with the hollow groove 39. The arc-shaped plate 54 is located at the upper end of the first arc-shaped block 38. When the first arc-shaped block 38 approaches the first arc-shaped groove 48 and compresses the plate 18, the arc-shaped plate 54 does not contact the plate 18; instead, the arc-shaped plate 54 directly contacts the first arc-shaped groove 48. The first arc-shaped block 38 at its lower end contacts the plate 18 and extrudes it into shape. When the first arc-shaped block 38 moves away from the first arc-shaped groove 48, the third spring 51 will reset. The reset of the third spring 51 will drive the second arc-shaped block 52 to move outward. The outward movement of the second arc-shaped block 52 will drive the third sliding block 53 to move outward. The outward movement of the third sliding block 53 will drive the arc plate 54 to move outward. At this time, the overall diameter of the first arc-shaped block 38 is reduced, which is convenient for unloading. The first arc-shaped block 38 is designed with a diameter that can be increased and decreased, which facilitates unloading. During stamping, the diameter of the first arc-shaped block 38 increases. When the first arc-shaped block 38 retracts, the diameter decreases, which makes it convenient for the stamped circular plate 18 to fall from its side and exit the mold through the first opening 112.
