Abstract
Description
Technical Field
[0001] The invention relates to the field of deep-drawn parts production, in particular to a parts continuous deep-drawing device. Background Art
[0002] At present, the deep drawing process is a stamping method that uses a deep drawing die to press a flat blank into a hollow workpiece with various openings, or to process the already made open hollow parts into other hollow parts. Deep drawing is also called drawing. Its deformation process is: as the punch continues to move downward, the outer diameter of the blank left on the end face of the die continues to shrink, and the circular blank is gradually pulled into the gap between the punch and the die to form a straight wall, and the material under the punch becomes the bottom of the deep drawing part. When the sheet material enters the gap between the punch and the die, the deep drawing process ends, and the flat blank becomes a cup-shaped part with a certain diameter and height. Compared with the blanking die, the working part of the deep drawing punch and die should not have a sharp edge, but a certain rounded corner, and the single-sided gap between the punch and the die is slightly larger than the material thickness. The deep drawing process can be used to produce cylindrical, stepped, spherical, conical, parabolic and other rotating parts.
[0003] At present, there are two stamping processes that can be used to draw a sheet into a cylindrical part, such as drawing out the battery shell of an electric vehicle. The first is to use a progressive die, which is mostly vertical. First, the aluminum sheet is divided into aluminum strips and rolled into a roll, and then fed into the progressive die. The progressive die consists of multiple stations, and each station is associated in sequence to complete different processing. A series of different stamping processes are completed in one stroke of the punch press, and the battery shell that meets the diameter is gradually stamped out on the aluminum strip, and the last step is blanking. The progressive die has a high degree of automation and is also suitable for the production of large quantities of parts, but the design difficulty, production difficulty, and maintenance cost of the progressive die are all very high, and the requirements for the press are also high. Once the strip material deviates or fails during the continuous feeding process, it is necessary to stop the machine for adjustment or a large number of scrapped products will be caused.
[0004] The second method is to use multiple sets of single-process molds or single-process molds in conjunction with compound molds. First, the strip material is blanked into multiple discs on the first die, and then the discs are initially drawn into cylindrical parts with flanges on the second die. According to the drawing requirements, a corresponding number of stretching dies are made to gradually draw the cylindrical parts with flanges until they are drawn into non-flange cylindrical parts that meet the diameter requirements. The design difficulty, production cost and maintenance cost of a single mold of a single-process mold or a compound mold are relatively low, but the degree of automation is low, and the production efficiency of parts is low.
[0005] With respect to the above-mentioned related technologies, the inventors believe that the two production processes in the related technologies may have problems with design difficulty, manufacturing difficulty, and high maintenance costs, or may have a low degree of automation and low production efficiency of parts, making it difficult to balance the defects of the current use of molds for deep drawing production of parts. Therefore, there is an urgent need for a process that does not require high difficulty in mold design, manufacturing, and maintenance, and is convenient for automated mass production of parts.

DETAILED DESCRIPTION
[0038] The following is combined with Figure 1-10 This application is described in further detail.
[0039] The present application embodiment discloses a continuous deep drawing device for parts. Figure 1 , Figure 2 and Figure 3 A part continuous drawing device includes a material storage box 1, a horizontal drawing die 4, and a stamping drive mechanism 71 for driving the horizontal drawing die 4 to perform a stamping action. The material storage box 1 is arranged vertically or tilted toward the horizontal drawing die 4. In this embodiment, the material storage box 1 is tilted toward the horizontal drawing die 4. The lower part of the material storage box 1 is located above the horizontal drawing die 4, and a part outlet 12 is opened at the lower part of the material storage box 1 corresponding to the first blanking notch 55.
[0040] Reference Figure 3 , a guide assembly 2 is provided in the storage box 1 corresponding to the part outlet 12, and the distance between adjacent guide assemblies 2 is less than the minimum size of the prefabricated part that can fall therebetween. The storage box 1 includes a base plate 13, and each group of guide assemblies 2 includes a first guide rod 21 and a second guide rod 22 movably mounted on the base plate 13, and a guide groove for the prefabricated part to enter is formed between the first guide rod 21 and the second guide rod 22, and the guide groove is provided corresponding to the part outlet 12. The prefabricated part in this embodiment is a circular cylindrical part 9 with a flange 92, and the final deep-drawn part is a cylindrical part 9 without a flange 92, which is used for the battery shell of an electric vehicle. The prefabricated cylindrical parts 9 are evenly distributed in the guide grooves, and are discharged from the part outlet 12 in a directional manner. In other embodiments, the part may also be a square cylindrical part.
[0041] Reference Figure 3 and Figure 4 An anti-blocking driving mechanism is installed at the storage box 1, and the anti-blocking driving mechanism pushes the first guide rod 21 and the second guide rod 22 to swing or vibrate intermittently to prevent the prefabricated cylindrical part 9 from being stuck in the guide groove due to inclination, or stuck on the first guide rod 21 and the second guide rod 22, so that the prefabricated cylindrical part 9 can be discharged continuously and smoothly.
[0042] Reference Figure 3 and Figure 4 The first guide rod 21 is provided with a first rotating rod 31 at a section close to the parts outlet 12, and the second guide rod 22 is provided with a second rotating rod 32 at a section away from the parts outlet 12. The first rotating rod 31 and the second rotating rod 32 are inserted into the bottom plate 13 and are rotatably connected to the bottom plate 13. The structure of the anti-blocking driving mechanism is not unique. In this embodiment, the anti-blocking driving mechanism includes a knocking plate 33 connected to the first rotating rod 31, a connecting rod 36 connected to the second rotating rod 32, a mounting plate 37 mounted in the bottom plate 13, a return spring 34 mounted on the mounting plate 37 and located between the connecting rod 36 and the mounting plate 37, and a cam 35 driven by a motor. The knocking plate 33 is intermittently knocked by the cam 35, thereby driving the first rotating rod 31 to rotate intermittently. The rotation of the first rotating rod 31 causes the first guide rod 21 to swing, and the swing of the first guide rod 21 drives the second guide rod 22 to swing accordingly. The second guide rod 22 swings to rotate the second rotating rod 32 . The return spring 34 is located in the swinging direction of the connecting rod 36 . The second rotating rod 32 can squeeze the return spring 34 so that the return spring 34 is compressed.
[0043] When the cam 35 does not hit the knocking plate 33, the connecting rod 36 is reset or even swung in the opposite direction under the rebound of the reset spring 34. The swinging back of the connecting rod 36 causes the second rotating rod 32 to rotate in the opposite direction, thereby causing the second guide rod 22 to swing in the opposite direction and driving the first guide rod 21 to reset or swing in the opposite direction. The connecting rod 36 displaces and compresses the reset spring 34. Under the rebound of the reset spring 34, the connecting rod 36 can be reset, causing the first guide rod 21 to intermittently swing around the first rotating rod 31, and causing the second guide rod 22 to intermittently swing around the second rotating rod 32.

[0045] A die groove 59 is provided on one side of the drawing portion 52. At least two die grooves 59 are provided and arranged in parallel along the height direction of the drawing portion 52. The inner diameter or width of the lower die groove 59 is smaller than the upper die groove 59. A blanking hole 58 is provided on one side of the blanking portion 54 corresponding to the die groove 59. The blanking hole 58 is coaxially arranged with the die groove 59. A blanking notch 55 is provided on the blanking portion 54 above the blanking hole 58. The blanking hole 58 located at the top of the blanking portion 54 is the first blanking hole 58.
[0046] The width or inner diameter of the first blanking hole 58 is equal to the width or outer diameter of the prefabricated part, and the width of the blanking notch 55 above the first blanking hole 58 is greater than or equal to the width or outer diameter of the prefabricated part. The width or inner diameter of the next blanking hole 58 is equal to the width or inner diameter of the previous die groove 59, and the width of the blanking notch 55 above the next blanking hole 58 is greater than or equal to the inner diameter of the previous die groove 59.
[0047] Reference Figure 7 The punch die set 6 includes a punch die 61 corresponding to the die groove 59, and the punch die 61 is mounted on the punch die fixing plate 43. A part demoulding assembly is provided on the movable die or the fixed die.
[0048] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment, the part demoulding assembly includes a convex plate 57 fixed on the blanking portion 54, one side of the convex plate 57 is located on the displacement path of the punch 61 away from the blanking hole 58, so that the part can be blocked by the convex plate 57 and detached from the punch 61. The first drawing station to the second to last drawing station all use the convex plate 57 for demoulding.
[0049] The part demoulding assembly can also be an air nozzle installed in the punch 61, and the gas with pressure is delivered to the air nozzle by the gas injector. The punch 61 is provided with an air hole 62 on the side facing the die groove 59, and the gas ejected from the air nozzle pushes the part to be separated from the punch 61. In this embodiment, the die groove 59 at the bottom of the drawing part 52 is a through groove, and the punch 61 corresponding to the die groove 59 is provided with an air nozzle, and a collection box 91 is provided on the side of the fixed mold away from the movable mold. The gas ejected from the air nozzle pushes the last deep-drawn part to enter the collection box 91 through the through groove.
[0050] Reference Figure 1 The stamping drive mechanism 71 includes a driving part and a transmission part. The driving part includes a driving box 7, a rotating shaft 72 rotatably connected to the driving box 7, and a rotating disk 73 eccentrically fixed to the rotating shaft 72. The rotating shaft 72 is driven by a motor to rotate, thereby driving the rotating disk 73 to rotate. Transmission shafts are arranged at both ends of the length direction of the punch fixing plate 43. The transmission part includes a rotating ring 74 sleeved on the outer periphery of the rotating disk 73, a sleeve sleeved on the outer periphery of the transmission shaft and rotatably connected to the transmission shaft, a connecting rod 81 connecting the rotating ring 74 and the sleeve, a guide sleeve 85 inserted in the movable mold, and a guide shaft 84 connecting the fixed mold and the driving box 7. The guide shaft 84 is inserted in the guide sleeve 85, and the axis of the guide shaft 84 is consistent with the drawing direction of the part. The rotation of the rotating disk 73 drives the connecting rod 81 to pull the punch fixing plate 43 to move in a directional manner along the guide shaft 84, so that the punch die set 6 and the die die set 5 are always aligned during each stamping process.
[0051] Reference Figure 1 A guide sleeve 86 is fixedly provided on the die fixing plate 41, and a guide column 87 is connected to the punch fixing plate 43. When the punch fixing plate 43 is stamped toward the die fixing plate 41, the guide column 87 is inserted into the guide sleeve 86 and plays a guiding role, thereby improving the stamping accuracy of the mold.
[0052] The implementation principle of a part continuous drawing device in the embodiment of the present application is as follows: a plurality of prefabricated cylindrical parts 9 with flanges 92 are punched out of a strip material by a blanking and drawing compound die or a blanking and drawing progressive die. The prefabricated cylindrical parts 9 are collected in a storage box, which is higher than a storage box 1. A plurality of parallel steel wire ropes are connected between the storage box and the storage box 1, and each steel wire rope forms a transmission track. The prefabricated cylindrical parts 9 in the storage box are continuously transmitted to the storage box 1 from the transmission track, and the flanges 92 face upward when entering the storage box 1. A gas injection mechanism is provided at the discharge port of the storage box and the feed port 11 of the storage box 1, and the gas injection mechanism is used to blow the prefabricated cylindrical parts 9 in the transmission track into the storage box 1. The feed port 11 of the storage box 1 is located on the side of the upper part of the storage box 1.
[0053] Under the blowing of the gas injection mechanism, the prefabricated cylindrical parts 9 can be blown to the innermost of the storage box 1. As the prefabricated cylindrical parts 9 are continuously blown into the storage box 1, the prefabricated cylindrical parts 9 will eventually be evenly distributed in the storage box 1 and evenly distributed at the outlets 12 of each part under the inclination of the storage box 1. When starting the horizontal drawing die 4, the horizontal drawing die 4 can be started to discharge the parts for drawing only after the storage box 1 is filled or nearly filled with the prefabricated cylindrical parts 9. This is convenient for the parts to be replenished without interruption during the drawing process.
[0054] The prefabricated cylindrical part 9 of the directional blanking enters the blanking hole 58 from the blanking notch 55 of the first blanking hole 58. As the punch driving mechanism 71 continuously drives the punch fixing plate 43 to move, the punch 61 passes through the blanking hole 58 to push the cylindrical part 9 in each blanking hole 58 into the die groove 59, so that the cylindrical part 9 is drawn and deformed in the die groove 59. After the punch 61 has drawn the cylindrical part 9, the cylindrical part 9 will be wrapped on the punch 61 while the punch 61 withdraws from the die groove 59. The cylindrical part 9 is blocked by the convex plate 57 and detached from the punch 61. The detached cylindrical part 9 enters the next blanking hole 58 through the blanking notch 55. In the process of the punch die set 6 being reciprocatedly inserted into the die die set 5, the same cylindrical part 9 is drawn one by one until it is drawn in place and blown out of the mold from the last die groove 59. The horizontal drawing die 4 enables the cylindrical member 9 to autonomously move downward to the drawing station and achieve continuous drawing, thereby facilitating mass production of the cylindrical member 9 .
[0055] Example 2
[0056] Reference Figure 8 The difference between this embodiment and the embodiment 1 is that the guide assembly 2 and the anti-blocking driving mechanism are not provided at the material storage box 1, but an anti-blocking vibration mechanism is provided, which drives the material storage box 1 to vibrate and prevents the parts from blocking the parts outlet 12. The anti-blocking vibration mechanism can use a vibration motor 10, which drives the material storage box 1 to vibrate, thereby preventing the prefabricated parts from blocking the parts outlet 12.
[0057] Example 3
[0058] Reference Fig. 9 and Fig.10 The difference between this embodiment and embodiment 1 is that the jet hole 62 is not provided on the punch 61 located at the bottom of the punch die assembly 6, the die groove 59 located at the bottom of the drawing portion 52 is not a through groove, the part demolding components all use a convex plate 57, each blanking portion 54 is provided with a discharge notch 56 below the bottom blanking hole 58, and the collecting box 91 is located below the horizontal drawing die 4 and between the movable die and the fixed die.
[0059] The implementation principle of the part continuous drawing device in the embodiment of the present application is that the parts after drawing are directly dropped from the discharge hole into the collection box 91.
[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
