Description

Technical Field

[0001] This utility model relates to a forming device for a washing machine reducer cover plate. Background Technology

[0002] Washing machines are a common household appliance. The washing machine reducer is the main component of the transmission system of a pulsator washing machine. Its function is to reduce the speed of the motor and increase the torque to drive the pulsator. The opening of the washing machine reducer housing is equipped with a cover plate. The cover plate is relatively thin and is made of metal stamping.

[0003] Because the cover plate also needs to be machined with structures such as cavities, ribs, and opening slots, the stamping process of the cover plate involves multiple forming steps. However, in the existing stamping process of cover plates, each forming step is carried out separately, which cannot form continuous processing. Moreover, each step requires manual loading and unloading of materials, which makes the operation extremely cumbersome. The processing is intermittent, which is both time-consuming and labor-intensive. At the same time, the semi-finished products must be transferred between adjacent forming steps, which further consumes time and leads to high labor intensity. In addition, the waste materials after processing need to be collected and sorted regularly, ultimately resulting in low processing efficiency and high labor costs, which need to be further improved.

[0035] A forming device for a washing machine reducer cover plate further includes a feeding and discharging mechanism 2 that cooperates with a continuous stamping mechanism 1.

[0038] The first guide unit also includes two clamping plates 210 that are vertically fixed to the top of the frame 21 and symmetrically arranged front and back, and a reduction cylinder 211 that is horizontally fixed between the two clamping plates 210. The two clamping plates 210 are located to the right of the first steering roller 24 and below the two second steering rollers 25.

[0039] Working principle:

[0040] One end of the strip wound on the feed reel 23 is pulled outward and sequentially passes under the first steering roller 24, above the second steering roller 25 on the left, below the reduction cylinder 211, above the second steering roller 25 on the right, and below the first guide roller 217. It then continues to extend to the right below the first forming frame 16. The telescopic end of the stamping cylinder 118 is then extended outward to move the first forming frame 16, second forming frame 17, third forming frame 18, fourth forming frame 19, and separating frame 11710 downward with the help of the lifting block 110. This allows two positioning holes to be punched out on the strip using the two round-hole cutting posts 112. Then, the telescopic end of the stamping cylinder 118 is retracted inward to similarly move the first forming frame 16, second forming frame 17, third forming frame 18, fourth forming frame 19, and separating frame 11710. All 10 move upwards and then continue to push the material belt to the right. When the two positioning holes are below the second forming frame 17, the first forming frame 16, the second forming frame 17, the third forming frame 18, the fourth forming frame 19 and the separating frame 11710 all move downwards again. Then, with the help of the first forming block 114 at the bottom of the second forming frame 17, a concave surface is formed between the two positioning holes. After the concave surface continues to be fed to the right, multiple forming strips 115 at the bottom of the third forming frame 18 will form ribs on the concave surface. After the concave surface continues to be fed to the right, the second forming block 116 at the bottom of the fourth forming frame 19 will form a flange at the edge of the concave surface. After the concave surface continues to be fed to the right, the frame-shaped blade 1179 at the bottom of the separating frame 11710 in the separating unit 117 will cut the area where the concave surface is located from the material belt to form the reducer cover plate.

[0041] Simultaneously, the rotating end of the rotary cylinder 1174 in the drive separation unit 117 rotates to drive the two slotted modules to rotate via the conversion plate 1175, thereby positioning one of the slotted modules directly below the first cavity 1112. Subsequently, the telescopic end of the drive lifting cylinder 1173 extends outward to drive the rotary cylinder 1174, conversion plate 1175, and the two slotted modules to move upward via the lifting frame 1172. The slotted module located directly below the first cavity 1112 passes upward through the first cavity 1112 and extends into the interior of the separation cavity 1111. Then, multiple slots are opened in the reducer cover plate using multiple slotting blades 1177, and the cut-off reducer cover plate remains on the top of the seat block 1176.

[0042] Next, the telescopic end of the driving lifting cylinder 1173 retracts inward to move both slotting modules downward. Then, the rotating end of the driving rotary cylinder 1174 rotates 180 degrees, thereby exchanging the positions of the two slotting modules. The slotting module with the reducer cover plate is located below the second cavity hole 131. When the other slotting module moves upward to perform the slotting operation, the slotting module with the reducer cover plate will also move upward and extend through the second cavity hole 131 to the top of the cabinet panel 13. Then, the reducer cover plate can be removed.

[0043] Subsequently, one end of the material belt extends above the support plate 1192 in the traction module 119, then passes through the frame 1193 of each pressing module and is located below each pressure plate 1195. Then, the telescopic end of the pressing cylinder 1194 in each pressing module is driven to extend outward to press the material belt against the bottom inner wall of each frame 1193 with the help of the pressure plate 1195. Then, the moving end of the electric slide table 1191 is driven to move to the right to pull the material belt to the right, thus realizing the automatic feeding of the material belt.

[0044] Subsequently, one end of the strip is sequentially wound around the bottom of the third steering roller 215, the bottom of each third guide roller 213, the bottom of the fourth guide roller 27 and the fifth guide roller 29, the right side of the fourth steering roller 28, and the bottom of the adjusting roller 26, and finally fixed on the discharge plate 216. After starting the winding motor 212 connected to the discharge plate 216 to make its rotating shaft rotate, the processed waste strip will be automatically wound up.

[0045] This invention integrates multiple forming steps of the washing machine reducer cover plate onto a single machine, with each step being automatically performed sequentially for continuous processing. This eliminates the need for frequent manual loading and unloading, greatly simplifying the operation and saving time and effort while significantly reducing labor intensity. It also saves considerable time and ensures uninterrupted processing. Furthermore, it automatically rewinds and organizes the processed waste material to further simplify the operation, thereby significantly improving processing efficiency and substantially reducing labor costs.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
