Description

Technical Field

[0001] This utility model belongs to the field of metal housing bending technology, specifically relating to an adjustable metal housing processing and bending equipment. Background Technology

[0002] In the field of metal casing processing, the bending process is a crucial step in shaping the casing structure, and its processing accuracy directly affects the assembly performance and appearance quality of the casing. Currently, traditional metal casing bending equipment still has many limitations in practical use: the limiting structures of existing bending equipment are mostly fixed, and their positions and spacing cannot be flexibly adjusted according to metal casing plates of different sizes and bending requirements. When processing casing plates of different specifications, manual disassembly and replacement or adjustment of the limiting components is required, which is cumbersome and time-consuming, severely reducing production efficiency. At the same time, the accuracy of manually adjusted limiting components is low, easily leading to inconsistent bending angles and excessive folding edge size errors due to positioning deviations, affecting product qualification rates. Furthermore, traditional limiting structures lack adaptive buffering functions, and often involve rigid contact when limiting metal casing plates. For thin or easily damaged sheet metal, hard contact can easily cause indentations, deformation, or even cracking of the sheet metal edges. If the limiting force is insufficient, the sheet metal is prone to slippage during bending, which further aggravates the accuracy deviation. Therefore, we propose an adjustable metal housing processing and bending equipment. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable metal housing processing and bending device, including a base 1, a worktable 2 fixed to the top of the base 1, a bending seat 3 fixed to the bottom surface of the worktable 2, a hydraulic press 4 fixed to the top surface of the worktable 2, a bending cutter 5 fixedly connected to the hydraulic press 4 on the surface of the worktable 2, and an adjustable bending limiting component inside the worktable 2. The adjustable bending limiting component includes a push plate 100 disposed inside the worktable 2, and symmetrically opened grooves 101 on both sides of the inner wall of the worktable 2. Slider blocks 102 are symmetrically fixed on both sides of the push plate 100, and the sliders 102 are engaged with the grooves 101. The push plate of the adjustable bending limiting component is engaged with the grooves on the inner wall of the worktable through the sliders, realizing the stable movement of the push plate in the worktable, providing basic structural support for flexible adjustment of the limiting position, solving the problem of the fixed and unadjustable traditional limiting structure, and initially meeting the limiting requirements of workpieces of different sizes.

[0020] In this embodiment, preferably, a guide groove 200 is formed through the surface of the slider 102, and a guide rod 201 is fixed inside the guide groove 200. The guide rod 201 is slidably connected to the guide groove 200, which further restricts the offset direction of the push plate when the slider moves along the groove, forming a double guide, enhancing the stability of the adjustment process, avoiding the deviation of the limit accuracy caused by the shaking of the push plate, and improving the adjustment accuracy.

[0021] In this embodiment, preferably, a bearing seat 300 is fixed to the inner side of the bending seat 3, and a screw hole 301 is opened through the surface of the push plate 100. A lead screw 302 is screwed into the bearing seat 300 and fixedly connected to the bearing seat 300. A drive motor 303 fixedly connected to the lead screw 302 is fixed inside the worktable 2. The motor drives the lead screw to rotate, and the screw transmission drives the push plate to move precisely, realizing the automatic adjustment of the limit position, replacing manual adjustment, reducing operation time, and the cooperation between the lead screw and the bearing seat ensures stable transmission and improves adjustment accuracy.

[0022] In this embodiment, preferably, a fixing plate 400 is symmetrically fixed on the surface of the push plate 100, and a baffle 401 is provided at the end of the fixing plate 400. The fixing plate is connected to the push plate to transmit the adjustment position, and the baffle directly contacts the metal housing plate to achieve the limit. The limit action point is clearly defined to ensure that the end positioning of the workpiece is reliable when bending, and to provide a guarantee for the bending accuracy.

[0023] In this embodiment, preferably, the end of the baffle 401 is symmetrically provided with connecting grooves 500, and the end of the baffle 401 is symmetrically fixed with connecting blocks 501. The connecting blocks 501 are slidably connected with the connecting grooves 500, so that the baffle can move relative to the fixed plate, providing structural margin for subsequent adaptive buffering or position fine adjustment, allowing the limiting structure to adapt to small differences in workpiece size and improving the limiting flexibility.

[0024] In this embodiment, preferably, the end of the connecting block 501 is provided with a telescopic groove 600, and a telescopic rod 601 embedded in the telescopic groove 600 is fixed inside the connecting groove 500. A telescopic spring 602 is sleeved on the surface of the telescopic rod 601. When the workpiece squeezes the baffle, the spring deformation can absorb the impact force, avoid hard contact that causes indentation or deformation on the workpiece surface, and achieve protection of the vulnerable plate.

[0025] In this embodiment, preferably, a locking groove 700 is provided on one side of the connecting block 501, and a through hole 701 is provided on one side of the inner wall of the connecting groove 500. Locking rods 702 that are screwed into the through hole 701 are symmetrically arranged on both sides of the fixing plate 400. By screwing the locking rods, the connecting block and the connecting groove are fixed, and the baffle is locked in a specific position, realizing the mode switching from adaptive buffering to hard limit, meeting the high-precision hard positioning requirements, and enhancing the applicable scenarios of the equipment.

[0026] The working principle and usage process of this utility model are as follows: When bending a metal casing plate, the drive motor 303 is first started, causing the lead screw 302 to rotate inside the bearing seat 300. This causes the lead screw 302 to engage with the screw hole 301, moving the push plate 100 inside the worktable 2 and the slider 102 inside the slide groove 101. Simultaneously, the guide groove 200 moves on the surface of the guide rod 201, providing a guiding function. After the push plate 100 moves the fixed plate 400 to the appropriate position, the drive motor 303 is stopped, allowing the push plate 100 to be positioned inside the worktable 2. At this point, the metal casing plate can be placed inside the bending seat 3 and pressed against the baffle 401 at the end of the fixed plate 400. The pressing position of the baffle 401 can be finely adjusted according to the bending requirements. If a portion of the metal casing plate is pushed, the connecting block 501 will be pushed through the baffle 401. The sliding mechanism inside the connecting groove 500 simultaneously causes the telescopic groove 600 to slide on the surface of the telescopic rod 601, compressing the telescopic spring 602 and causing deformation. This changes the position of the baffle 401, achieving adaptive limiting of the metal housing plate end. Then, the hydraulic press 4 can be activated to press down the bending knife 5 to bend the metal housing plate. When rigid limiting by the baffle 401 is required, the baffle 401 can be pushed, causing the connecting block 501 to retract into the connecting groove 500. Simultaneously, the telescopic groove 600 slides on the surface of the telescopic rod 601, compressing the telescopic spring 602 and causing deformation. This ensures that the locking groove 700 and the through hole 701 are accurately aligned. Then, the locking rod 702 is tightened, causing it to rotate inside the through hole 701 and engage with the locking groove 700 for a fixed connection. This positions the baffle 401, preventing it from adaptively adjusting and thus rigidly clamping the metal housing plate.

[0027] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
