Description

Technical Field

[0002] In modern industrial manufacturing, housing components are widely used in a variety of key industries, including electronics, automotive, aerospace, and medical devices. For example, electronic device casings, lightweight components for automotive engines, and precision structural parts in the aerospace industry all place extremely high demands on housing performance indicators such as thickness uniformity, surface accuracy, and structural strength. As the global manufacturing industry evolves towards lightweighting, high precision, and integration, the importance of housing thinning processing technology, a core process for reducing component weight, increasing efficiency, and improving overall performance, is becoming increasingly prominent. Currently, thinning of shells is primarily accomplished through processes such as stamping, spinning, stretching, and roll forming. Stamping, due to its high production efficiency and suitability for large-scale processing, is widely used in thin-sheet shell processing.

[0014] Working principle: When the device needs to be used, first rotate the first adjusting rod to drive the ratchet and the first threaded rod to rotate. At this time, the first threaded rod drives the second adjusting sleeve on one side to slide under the limit of the sliding rod, thereby adjusting the installation sleeve. When the installation sleeve is adjusted, the size of the rubber adjustment sleeve and the forming sleeve can be adjusted according to the production size, so as to achieve the effect of rapid adaptation to production. During use, the rubber adjustment sleeve can prevent the flexible rebound of the blank when it contacts the extension ring, and reduce the process difficulties of excessive rigidity and instantaneous instability of the metal when the blank is put into the mold. During the adjustment process of the installation sleeve, the second adjustment sleeves on both sides can be controlled to move synchronously through the limit of the connecting rod and the limit sleeve, thereby reducing the deviation of the rubber adjustment sleeve and the forming sleeve during the installation process. The steel plate or product to be thinned is placed on the shell, and the hydraulic cylinder is activated to drive the pressing plate and the punch to descend, thereby thinning the steel plate. When the processing is completed and reaches the bottom of the shell, the thinned steel plate outside the punch is removed by the stripping rod. At this time, the top block of the pressing plate during the descent drives the first rack to drive the first gear to rotate, thereby driving the second connecting rod and the bracket to rise and fall through the second adjusting rod. During use, it plays an effect of assisting the material connection of the processed product, and avoids the deformation of the thinned steel plate due to side fall caused by residual heat during use. Secondly, the main splint and the second gear have the effect of assisting the fixation of the steel plate. When the electric slider and the electric slide rail arranged below cooperate with each other, the first connecting rod slides under the limit of the limit plate through the first connecting rod, and the material plate is driven to slide under the limit of the guide rail during the movement by the limit plate, so that the material is taken out. After taking out, the main splint and the second gear also have the effect of auxiliary support for the material, and in the process of use, further avoid the material from tipping over during taking out and causing damage to the product, and also have the effect of protecting the operator. The clamped material is not only convenient to be taken out, but also combined with the second gear and the second rack, the second gear is driven to move by the second screw when taking out, and the fixed plate and the auxiliary splint are further used to clamp the product during use, thereby avoiding the product from tipping over during taking out, thereby protecting the product and the operator.

[0015] The present invention provides a shell thinning and forming processing device. It has the following beneficial effects: 1. The present invention drives the first threaded rod to drive the second adjusting sleeve to slide under the limit of the slide rod by rotating the first adjusting rod. When the installation sleeve is opened, the rubber adjusting sleeve and the forming sleeve can be quickly installed and removed. During use, the rubber adjusting sleeve can make the blank have flexible rebound when contacting the extension ring, thereby reducing the process problem of excessive rigidity of the blank when entering the mold and instantaneous instability of the metal.

[0016] 2. The present invention drives the first connecting rod to slide in the limiting groove of the limiting plate, thereby driving the limiting plate to pull the material plate to slide under the limit of the guide rail, thereby achieving the effect of quickly taking out the received material during use.

[0017] 3. The present invention drives the second adjusting rod and the second connecting rod to slide inside the fixed platform by rotating the first gear, so that the main splint and the second gear move upward during use, thereby fixing the product to prevent it from tipping over, thereby protecting the product. When taking materials, it also has the effect of protecting the operator to prevent injury caused by tipping over. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1 Please see the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a shell thinning forming processing device, including a shell 1, the outer wall of the shell 1 is fixedly connected to a first adjusting sleeve 2, the inner wall of the first adjusting sleeve 2 is rotatably connected to a first adjusting rod 3, the outer wall of the first adjusting rod 3 is fixedly connected to a ratchet 4, the tooth end of the ratchet 4 is meshed with a pawl 5, the left end of the first adjusting rod 3 is fixedly connected to a first threaded rod 6, the outer wall of the first threaded rod 6 is threadedly connected to a second adjusting sleeve 8, the inner wall of the second adjusting sleeve 8 is slidably connected to a sliding rod 7, the outer wall of the sliding rod 7 is fixedly connected to the inner wall of the shell 1, the outer wall of the second adjusting sleeve 8 is fixedly connected to a mounting sleeve 11, a rubber adjusting sleeve 12 is provided inside the mounting sleeve 11, the upper part of the rubber adjusting sleeve 12 is fixedly connected to a forming sleeve 13, the outer wall of the second adjusting sleeve 8 is rotatably connected to a connecting rod 9, the outer wall of the connecting rod 9 is rotatably connected to a limiting sleeve 10, the outer wall of the limiting sleeve 10 is rotatably connected to the inner wall of the shell 1, a pop-up component is provided on the lower side of the shell 1, a material receiving component is provided on the upper side of the pop-up component, and a processing component is provided on the upper side of the shell 1.

[0022] Specifically, the current traditional manufacturing method generally uses rod material to extrude a thick shell blank, and then uses stretching to thin it. After multiple stretching deformations, a thin-walled shell is finally obtained. During use, the door panel is opened, and the ratchet 4 is driven to rotate by rotating the first adjusting rod 3. At this time, the second adjusting sleeve 8 is driven to slide under the limit of the slide rod 7 by the first threaded rod 6, so that the installation sleeve 11 can be controlled to open and close during use. During use, when the second adjusting sleeve 8 moves, the limiting sleeve 10 is driven to rotate on the inner wall of the shell 1 by the connecting rod 9, which can synchronously control the movement of the second adjusting sleeve 8 on the other side. When in use, the second adjusting sleeve 8 is set in two opposite groups, only one group is threadedly connected to the first threaded rod 6, and the other is sliding. After the sleeve 11 is opened, the rubber adjusting sleeve 12 and the forming sleeve 13 can be quickly installed and removed. During use, the rubber adjusting sleeve 12 can make the blank have flexible rebound when contacting the stretching ring, reduce the process difficulties of excessive rigidity when the blank enters the mold and instantaneous instability of the metal, and can quickly replace rubber adjusting sleeves 12 and forming sleeves 13 of different sizes for use. During use, it is avoided that when thinning and stretching are performed, due to the rigidity of the stretching ring mold, when contacting the blank, if the ring diameter is too large, the deformation is not sufficient, and multiple thinning processes are required, which increases the process; if the ring diameter is too small, the material will be scraped, causing the surface metal to accumulate on the upper half of the shell to form wrinkles, and some even directly shrink and crack.

[0023] Please see the attached Figure 4 -Attached Figure 6 The ejection assembly includes a limit plate 22, the outer wall of which is slidably connected to the inner wall of the housing 1. The inner wall of the limit plate 22 is slidably connected to a first connecting rod 21, and the outer wall of the first connecting rod 21 is fixedly connected to an electric slider 20. The inner surface of the electric slider 20 is provided with an electric slide rail, the lower surface of which is fixedly connected to the inner bottom wall of the housing 1. The upper surface of the limit plate 22 is fixedly connected to the peeling rod 16. The outer walls of both sides of the peeling rod 16 are fixedly connected to guide rails 17, and the outer walls of the guide rails 17 are fixedly connected to the inner wall of the housing 1.

[0024] Specifically, after thinning and extension, the product comes to the bottom of the shell 1. At this time, it is removed by the peeling rod 16, the processing component is extended, and it is received by the material receiving component to open the door panel. This is achieved by starting the electric slider 20 to slide on the electric slide rail, and driving the first connecting rod 21 to slide in the limiting groove of the limiting plate 22, thereby driving the limiting plate 22 to pull the material plate 18 to slide under the limit of the guide rail 17, thereby achieving the effect of quickly taking out the received material during use. Because the deep-stretched steel plate has residual heat during and after deformation, this method avoids high temperature burns and also does not affect the above processing, that is, dividing the taken-out material and the processed material into two areas to prevent the machine from hurting people. At the same time, it can not affect the loading of the material during the material taking process, thereby speeding up the production speed.

[0025] Please see the attached Figure 4 The processing assembly includes a support frame 23, the lower surface of which is fixedly connected to the upper surface of the housing 1. A hydraulic cylinder 24 is fixedly connected to the upper surface of the support frame 23. The output end of the hydraulic cylinder 24 passes through the support frame 23 and is fixedly connected to a pressure plate 25. A punch 26 is fixedly connected to the lower surface of the pressure plate 25, and the lower surface of the pressure plate 25 is fixedly connected to the bottom plate 15. The bottom plate 15 is fixedly connected to the inner wall of the middle portion of the housing 1. The inner wall of the bottom plate 15 is slidably connected to the first rack 14. The outer wall of the first rack 14 is slidably connected to the inner wall of the bottom plate 15. The lower side of the bottom plate 15 is rotatably connected to the peeling rod 16. A return spring is connected between the upper part of the peeling rod 16 and the bottom plate 15. A top block is provided on the lower side of the pressure plate 25, corresponding to the upper part of the first rack 14. The top block passes through the top of the housing 1 and is slidably connected to the upper surface of the first rack 14. A return spring is provided on the outside of the first rack 14.

[0026] Specifically, by starting the hydraulic cylinder 24, the pressure plate 25 and the punch 26 are driven to slide under the limit of the support frame 23. During use, the top block fixed on the pressure plate 25 above the first rack 14 drives the first rack 14 to descend, so that when the punch 26 passes through the forming area, the formed product is sent to the bottom, and then the produced product is removed by the stripping rod 16 in cooperation with the spring. At the same time, during the advancement process, the first rack 14 drives the first gear 29 to rotate, and the first gear 29 drives the second adjusting rod 30 and the second connecting rod 31. At this time, it has the effect of adjusting the height of the bracket 32. During use, the rise of the bracket 32 ​​is not for receiving materials, but for protecting the materials to prevent them from tilting to both sides due to lack of support at the bottom of the shell 1. The products that have just been produced will be deformed due to heat problems when they are bumped. The position of the second gear 35 can be adjusted in advance by the bracket 32 ​​and the main splint 34 in cooperation with the second gear 35 during use, thereby avoiding deformation caused by side falls during use.

[0027] The present invention provides multiple embodiments, wherein the material receiving assembly includes two embodiments, and two modes are set during production for use when unloading materials, and can be used interchangeably, wherein: Please see the attached Figure 7 The material receiving assembly includes a fixed platform 27, the lower surface of which is fixedly connected to the upper surface of the material plate 18. An adjustment block 28 is fixedly connected to the inner wall of the fixed platform 27. The inner wall of the adjustment block 28 is provided with a rotating shaft and fixedly connected to a first gear 29. A second adjustment rod 30 is fixedly connected to the surface of the rotating shaft. A second connecting rod 31 is rotatably connected to the inner wall of the second adjustment rod 30. The outer wall of the second connecting rod 31 is rotatably connected to a bracket 32. The outer wall of the bracket 32 ​​is slidably connected to the inner wall of the fixed platform 27. The outer wall of the bracket 32 ​​is fixedly connected to a main plate 34, and the outer wall of the main plate 34 is provided with two opposing second gears 35.

[0028] Specifically, when the first rack 14 descends and drives the first gear 29 to rotate, the second connecting rod 31 is driven by the rotating shaft inside the first gear 29 and the second adjusting rod 30 to drive the bracket 32 ​​to rise and fall. During use, it is driven to rise by product production. At this time, after the stripping rod 16 takes out the material, the bracket 32 ​​and the main splint 34 have the effect of protecting the material, which not only avoids deformation caused by collision due to residual heat, but also prevents the product from shaking. Secondly, during use, after rising, the bracket 32 ​​descends, and at this time it is driven to move outward by the electric slider 20 and the first connecting rod 21. The lowered bracket 32 ​​not only has the effect of fixing and protecting the product, but also has the effect of facilitating unloading. The product is fixed, so it is prevented from rolling and tipping over when taking it out, and it also has the effect of protecting the surrounding operators, which can further improve the safety during unloading.

[0029] Example 2: like Figure 8As shown, the main splint 34 on one side is removed and replaced with a second screw 37, and a fixing plate 19 is installed on the second gear 35. The fixing plate 19 passes through the second gear 35 and is provided with an auxiliary splint 33 made of rubber on the front side, and a roller is provided in the middle of the auxiliary splint 33. The roller plays a role of guiding the sliding out when taking out the material, and a return spring is provided on the outside of the fixing plate 19, thereby connecting the second screw 37 with the second gear 35. After production, the material will drive the second gear 35 forward under the rotation of the second screw 37 during the taking-out process, and the fixing plate 19 and the second gear 35 cooperate with the spring to form a flexible clamping, and the second gear 35 is in the first The cooperation of the two racks 36 has the effect of centering movement, thereby playing the effect of clamping and taking out the material during use, and fixing the product during use. In cooperation with the roller, it not only avoids the deformation of the product due to excessive clamping during use, but also assists in unloading, avoiding the product from causing harm to the surrounding operators due to side impact when taking out, thereby playing a protective effect. Moreover, embodiment 1 and embodiment 2 can be used in combination, which not only plays the effect of upward material collection when descending, but also performs secondary clamping when taking out, further avoiding the side deformation of the product, and playing a protective effect on the operator when taking out.

[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
