Description

Technical Field

[0001] This application relates to the field of stamping technology for household appliance housings, and more specifically, to a fixing component for stamping sheet metal housings for household appliances. Background Technology

[0002] Sheet metal stamping equipment for home appliance casings is used to produce metal casings for home appliances. Through stamping machinery and customized molds, metal sheets (such as steel plates and aluminum plates) are processed into the required shapes. This equipment is widely used in the home appliance manufacturing industry. For example, the casings of refrigerators, air conditioners, and washing machines are all produced using this process.

[0003] In related technologies, the shell stamping equipment does not have an auxiliary clamping function, which easily causes the stamped parts to shift during the stamping process. To solve the above problems, for example, the prior art patent with publication number CN216968433U provides a stamping device for home appliance shells that prevents positional shift. This device places the shell to be stamped into the stamping die, and then rotates the motor to drive the rotating rod to rotate. This causes the two vertical plates to move away from or towards each other on the rotating rod, thereby driving the clamping plate on the horizontal plate to pass into the stamping die and stamp the shell to be stamped in the stamping die. During operation, the stamping punch is raised and lowered by the telescopic motor, thereby cooperating with the stamping die to complete the stamping work. This stamping device for home appliance shells effectively prevents stamping positional shift that leads to economic waste.

[0004] Although the existing technical solutions mentioned above can fix the sheet metal parts by moving two clamping plates and prevent the sheet metal parts from shifting during stamping, the sheet metal parts will deform during stamping. The structure of the clamping plates is too simple. When the sheet metal parts are deformed, they will squeeze and rub against the clamping plates, which will affect the quality of the appliance shell after processing.

[0005] In view of this, we propose a fixing component for sheet metal stamping of household appliance housings. Utility Model Content

Detailed Implementation

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 This application discloses a fixing component for stamping sheet metal of a household appliance shell, including an operating frame 1. A stamping punch 2 is provided on the inner side of the operating frame 1. A stamping die 3 is provided on the top of the stamping punch 2. The stamping die 3 is used to cooperate with the stamping punch 2 to stamp the sheet metal body 100. Fixing components 4 are provided on both sides of the stamping punch 2. The fixing components 4 include four clamping blocks 41. The four clamping blocks 41 are used to fix the sheet metal body 100. A movable structure 42 is provided on the outer side of each of the four clamping blocks 41.

[0034] Before stamping, the sheet metal body 100 is fixed by four clamping blocks 41. Then, the stamping die 3 descends and cooperates with the stamping punch 2 to stamp the sheet metal body 100. The sheet metal body 100 deforms during stamping, which can push the corresponding clamping block 41. The corresponding clamping block 41 moves under the drive of the corresponding moving structure 42, so that while the clamping block 41 fixes the sheet metal body 100, the moving structure 42 can prevent the sheet metal body 100 from being squeezed by the clamping block 41 when it deforms.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Both movable structures 42 are provided with drive structures 43 on their outer sides. The two drive structures 43 are used to drive the two clamping blocks 41 to move closer to each other to fix the sheet metal body 100. The top of the stamping die 3 is provided with a hydraulic cylinder A31, which is used to drive the hydraulic cylinder A31 to rise and fall.

[0036] Two drive structures 43 are used to drive the moving structure 42 to move, thereby driving the two clamping blocks 41 to move and fix the sheet metal body 100, ensuring the fixing effect of the equipment. The hydraulic cylinder A31 can drive the stamping die 3 to rise and fall, ensuring the stamping effect of the equipment.

[0037] Reference Figure 1 - Figure 7Each of the four clamping blocks 41 has a threaded opening 411 on its inner side, and a bolt 412 is threaded onto the inner side of each of the four threaded openings 411. The bottom of each of the four bolts 412 is rotatably mounted on the inner side of the L-shaped plate 413. The feature is that each of the four L-shaped plates 413 has two sliding grooves A4131 on its inner side, and a slider 4132 is slidably mounted on the inner side of each sliding groove A4131. The outer side of each slider 4132 is fixedly mounted to the inner side of the corresponding clamping block 41. Each of the four moving structures 42 includes a spring 421. One end of each spring 421 is fixedly mounted to the outer side of the corresponding L-shaped plate 413, and the other end of each spring 421 is fixedly mounted with a fixing plate 423. Four fixing posts 4232 are fixedly mounted on the outer side of each fixing plate 423. The inner side of each spring 421 is sleeved with... There are four connecting columns 422. One end of each of the four connecting columns 422 is fixedly set to the outer side of the corresponding L-shaped plate 413. Two sliding grooves B4221 are opened on the outer side of each of the four connecting columns 422. Sliding grooves C4231 matching the sliding grooves B4221 are opened on the inner side of each of the four fixed plates 423. Each of the four connecting columns 422 is slidably set on the inner side of the corresponding fixed plate 423 through the corresponding two sliding grooves B4221 and the corresponding sliding grooves C4231. Each of the two drive structures 43 includes a connecting plate 431. One side of each of the two connecting plates 431 is fixedly set to the outer side of the corresponding two moving structures 42. The outer side of each of the two connecting plates 431 is fixedly set to the output end of the corresponding hydraulic cylinder B432. Each of the two hydraulic cylinders B432 is fixedly set on the inner side of the operating frame 1 through the corresponding support base 433.

[0038] When fixing the sheet metal body 100, the corresponding hydraulic cylinder B432 drives the corresponding connecting plate 431 to move, thereby driving the corresponding multiple fixing columns 4232 and the corresponding fixing plate 423 to move, so that the corresponding fixing plate 423 drives the corresponding connecting column 422 and spring 421 to move, thereby driving the corresponding L-shaped plate 413 to move, and the corresponding L-shaped plate 413 drives the corresponding clamping block 41 to move, and the four clamping blocks 41 fix the sheet metal body 100.

[0039] During stamping, if the sheet metal body 100 deforms, it will cause the corresponding clamping block 41 to move, thereby causing the L-shaped plate 413 to move. The L-shaped plate 413 moves under the elastic effect of the spring 421, so that the clamping block 41 can both fit tightly against the sheet metal body 100 and move through the moving structure 42 under the push of the deformation of the sheet metal body 100, preventing the clamping block 41 from being squeezed against the sheet metal body 100. When the L-shaped plate 413 moves, it will cause the connecting column 422 to move. Through the cooperation of the slide groove B4221 and the slide groove C4231, the connecting column 422 slides in the slide groove C4231 of the fixed plate 423, so that the connecting column 422 can protect the spring 421, prevent the spring 421 from bending, and ensure the normal use of the clamping block 41.

[0040] When fixing sheet metal parts 100 of different thicknesses, the clamping block 41 is moved by rotating the bolt 412, so that the clamping block 41 is suitable for sheet metal parts 100 of different thicknesses. The sliding groove A4131 and the slider 4132 cooperate to limit the clamping block 41.

[0041] In summary, the fixing component for stamping sheet metal of household appliance housing disclosed in this application, when in use, drives the clamping block 41 to move by rotating the bolt 412, which engages with the threaded port 411, so that the clamping block 41 can be adapted to sheet metal body 100 of different thicknesses.

[0042] The corresponding hydraulic cylinder B432 drives the corresponding connecting plate 431 to move, thereby driving the corresponding multiple fixed columns 4232 and the corresponding fixed plate 423 to move, so that the corresponding fixed plate 423 drives the corresponding connecting column 422 and spring 421 to move, thereby driving the corresponding L-shaped plate 413 to move, and the corresponding L-shaped plate 413 drives the corresponding clamping block 41 to move, and the four clamping blocks 41 fix the sheet metal body 100.

[0043] The stamping die 3 is driven to descend by the hydraulic cylinder A31, and the stamping punch 2 is used to stamp the sheet metal body 100. If the sheet metal body 100 deforms during stamping, it will drive the corresponding clamping block 41 to move, thereby driving the L-shaped plate 413 to move. The L-shaped plate 413 moves under the elastic effect of the spring 421, so that the clamping block 41 can both stick tightly to the sheet metal body 100 and move through the moving structure 42 under the push of the deformation of the sheet metal body 100, preventing the clamping block 41 from squeezing the sheet metal body 100.
