Description

Technical Field

[0001] This utility model relates to the field of washing machine inner drum processing technology, specifically to an automatic positioning and forming device for washing machine inner drum. Background Technology

[0002] During the stamping process of the washing machine inner drum, the raw material to be processed is first placed on the upper surface of the lower die. Then, the cylinder is activated, and the pushing force of the cylinder drives the upper die to move downward. The upper die then presses the raw material into the lower die, thus completing the stamping and shaping of the washing machine inner drum. Before the upper die stamps the raw material, it is necessary to manually place the raw material on the upper surface of the lower die. In order to ensure the stamping accuracy, manual positioning is also required. However, manual positioning not only increases the complexity of the operation and reduces the efficiency of stamping the washing machine inner drum, but also easily affects the quality of the stamping of the washing machine inner drum due to human positioning errors.

[0003] Therefore, there is an urgent need for an automatic positioning and forming device for the inner drum of a washing machine to solve the above problems. Utility Model Content

Detailed Implementation

[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] Example 1

[0020] Please see Figures 1-4 The figure shows an automatic positioning and forming device for a washing machine inner drum, including a base plate 101 and four mounting rods 102 arranged symmetrically in pairs on one side of the base plate 101. A top plate 103 is fixedly connected to one end of the four mounting rods 102 away from the base plate 101. A sliding plate 104 is slidably connected to the side wall between the base plate 101 and the top plate 103 of the four mounting rods 102. An upper mold 105 is provided on the side of the sliding plate 104 near the base plate 101, and a lower mold 106 is provided on the side of the base plate 101 near the top plate 103. A cylinder 107 for pushing the upper mold 105 is provided on the side of the top plate 103 away from the base plate 101. The device also includes a positioning component provided on the sliding plate 104 for automatically positioning the raw material of the washing machine inner drum during stamping and forming.

[0021] The positioning assembly includes a positioning ring 201 slidably connected to the side of the sliding plate 104 near the upper mold 105. The positioning ring 201 is sleeved on the side wall of the upper mold 105. The sliding plate 104 is provided with a pushing assembly for pushing the positioning ring 201. The side wall of the positioning ring 201 is provided with a plurality of fixing holes 202. Each fixing hole 202 is connected to a positioning tube 203 through a fixing assembly. Each positioning tube 203 is connected to a positioning ball 204 through a pressing assembly. The lower mold 106 is provided with a positioning sleeve 205 on the side near the upper mold 105.

[0022] It should be noted that, through the setting of the positioning components, under the continuous pressing and pushing action of multiple positioning balls 204 arranged in a ring array and the initial limiting action of the positioning sleeve 205, limiting forces are applied to the raw material from different directions, so that the raw material can be effectively positioned in both the horizontal and vertical directions. This not only achieves further straightening of the raw material, but also reduces the risk of tilting or swaying of the raw material, and realizes automatic positioning of the raw material without manual operation. This reduces the complexity of operation, improves the stamping efficiency of the washing machine inner drum, and reduces the quality risk caused by human positioning errors in the stamping of the washing machine inner drum.

[0023] It is worth noting that the specific operating steps and principles of stamping and forming the inner drum of a washing machine can be found in the authorized publication number CN220295675U, "An Automatic Positioning Washing Machine Inner Drum Forming Equipment", which will not be elaborated on here.

[0024] It should be emphasized that the model of cylinder 107 is CGIBN20-120. As this is existing technology, it will not be discussed in detail here.

[0025] Please see Figure 3 and Figure 4 The fixing components shown in the figure include a fixing plate 301 disposed on the side of the positioning ring 201 away from the positioning ball 204, one end of the positioning tube 203 being connected to the fixing plate 301, two bolts 302 being threadedly connected to the side wall of the fixing plate 301, and two threaded holes 303 being provided on the side wall of the positioning ring 201, the two threaded holes 303 being matched with the bolts 302.

[0026] It should be noted here that the setting of the fixing component makes it easy to install the positioning tube 203 onto the positioning ring 201.

[0027] Please see Figure 3 and Figure 4 The extrusion assembly shown in the figure includes an extrusion plate 401 slidably connected to the positioning tube 203. An extrusion rod 402 is fixedly connected to the side of the extrusion plate 401 near the lower die 106. A through hole is opened on the side of the positioning tube 203 near the positioning ball 204. The other end of the extrusion rod 402 is slidably connected to the through hole and connected to the positioning ball 204. A first spring 403 is connected to the side of the extrusion plate 401 away from the extrusion rod 402 through a connecting assembly. The other end of the first spring 403 is connected to the bottom wall of the positioning tube 203. The positioning tube 203 is provided with a rotating assembly for rotating the positioning ball 204 during the retraction process.

[0028] It should be noted here that the extrusion component is used to push the positioning ball 204 against the surface of the raw material with elasticity and to continuously press and straighten it.

[0029] Please see Figure 3 and Figure 4 The rotating assembly shown in the figure includes a spiral groove 501 formed on the side wall of the extrusion rod 402. The spiral groove 501 is provided with a clamping rod 502, one end of which is connected to the inner wall of the through hole.

[0030] It should be noted here that by setting up the rotating component, the force of the screw-in rotation is increased, thereby enhancing the positioning effect of the raw material.

[0031] It is worth noting that the hardness of the positioning ball 204 is less than that of the raw material, and under the elastic action of the extrusion component, it will not cause scratches on the surface of the raw material due to rotation.

[0032] Please see Figure 3 and Figure 4 The connecting assembly shown in the figure includes a connecting hole 601 opened on the side of the extrusion plate 401 away from the extrusion rod 402, a connecting ring 602 rotatably connected to the connecting hole 601, and the end of the first spring 403 near the extrusion rod 402 connected to the connecting ring 602.

[0033] It should be noted that the connection components are designed to prevent the first spring 403 from twisting or deforming during the rotation of the compression rod 402.

[0034] Working principle: During the stamping process of the washing machine inner drum, the raw material to be processed is first placed in the positioning sleeve 205 on the upper surface of the lower die 106 to perform preliminary positioning of the raw material. Then, the cylinder 107 is activated, and the pushing force of the cylinder 107 drives the upper die 105 to move downward, thereby using the upper die 105 to stamp the raw material into the lower die 106, thus completing the stamping and shaping of the washing machine inner drum.

[0035] Furthermore, as the upper die 105 moves closer to the raw material, it will simultaneously drive the positioning ring 201 to move closer to the raw material. Before the upper die 105 contacts the raw material, multiple positioning balls 204 on one side of the positioning ring 201 will first abut against the surface of the raw material under the pushing action of the extrusion component. Thus, under the continuous pressing and pushing action of multiple positioning balls 204 arranged in a ring array and the limiting action of the positioning sleeve 205, limiting forces are applied to the raw material from different directions, so that the raw material can be effectively positioned in both the horizontal and vertical directions. This not only achieves further pressing and straightening of the raw material, but also reduces the risk of the raw material tilting and swaying. This achieves automatic positioning of the raw material without the need for manual operation. This reduces the complexity of operation, improves the efficiency of the stamping and forming of the washing machine inner drum, and reduces the quality risk caused by human positioning errors in the stamping and forming of the washing machine inner drum.

[0036] Furthermore, as the upper mold 105 continues to approach the lower mold 106, the extrusion rods 402 at one end of each positioning ball 204 will retract into the positioning tube 203 under the action of extrusion force. During the retraction of the extrusion rods 402, the raw material will be continuously pressed and aligned under the action of extrusion force, thereby maintaining the positioning effect of the raw material. At the same time, during the retraction of the extrusion rods 402, under the spiral pushing action of the clamping rod 502 and the spiral groove 501, the extrusion rods 402 will rotate, thereby driving the positioning balls 204 to rotate on the surface of the raw material. Thus, by using the spiraling rotation action, the clamping force on the raw material is increased, thereby enhancing the positioning effect of the raw material.

[0037] Example 2

[0038] Please see Figure 2 and Figure 3 This embodiment further illustrates Example 1. The pushing assembly shown in the figure includes two T-shaped rods 701 fixedly connected to the sliding plate 104 near the upper mold 105. The two T-shaped rods 701 are slidably connected to a pushing plate 702. One end of the two pushing plates 702 is connected to a positioning ring 201. The sidewalls of the two T-shaped rods 701 are fitted with second springs 703. The two ends of the two second springs 703 are respectively connected to the sliding plate 104 and the pushing plate 702.

[0039] It should be noted here that the setting of the pushing component is used to drive the positioning ring 201 to move up and down. At the same time, when the upper die 105 is stamping the raw material, it is used to make the positioning ring 201 slide relative to the upper die 105.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
