Description
Technical Field
[0001] This utility model relates to the field of washing machine manufacturing technology, and in particular to a pre-bending device for washing machine manufacturing. Background Technology
[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. According to its rated washing capacity, it is divided into two categories: household and commercial. In the production process of washing machines, the outer shell and reinforcing ribs of the washing machine have bends. The bends of the outer shell and reinforcing ribs of the washing machine are processed by bending equipment. The outer shell and reinforcing ribs of the washing machine are pre-bent by bending equipment.
[0003] Typically, the material for a washing machine is placed in the mold below, and a bending head moves downwards, pushing the bending head to create a groove at the contact point, thereby bending the material. However, during the production of a washing machine, the pre-bending angles of the outer shell and reinforcing ribs are different, and the bending angles at different locations are also different, so the bottom mold needs to be adjusted.
[0004] Existing bending equipment relies heavily on manual operation for die position adjustment, such as using hand-cranked screws and bolts for fixing, and relying on human experience to judge the spacing. Moreover, it requires adjustment of both dies, and the position of the dies is prone to deviation. When errors occur, the sheet metal is easily subjected to uneven stress during bending, resulting in angle deviation, wrinkles, or cracks. Based on the above problems, this application proposes a pre-bending device for washing machine production. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a pre-bending device for washing machine production, which solves the aforementioned problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pre-bending device for washing machine production includes a mounting base, a mounting shell fixedly mounted on the top of the mounting base, a lateral moving component mounted on the front side of the mounting shell, a left mold and a right mold overlapping the top of the mounting shell, a connecting component between the bottom of the left mold and the bottom of the right mold, a mounting frame fixedly mounted on the top of the mounting base, and a bending component mounted on the surface of the mounting frame.
[0007] Preferably, the lateral movement component includes a connecting housing fixedly installed on the front side of the mounting base, a sliding groove being provided through the top of the connecting housing, a stepper motor being fixedly installed on the left side of the connecting housing, a lead screw being fixedly installed at the output end of the stepper motor, a threaded sleeve being provided on the surface of the lead screw, a connecting plate being fixedly installed on the top of the threaded sleeve, and the connecting plate being slidably disposed inside the sliding groove.
[0008] Preferably, the connecting plate has an L-shaped structure, is made of metal, and is fixedly installed on the front side of the left mold on the side away from the wire sleeve.
[0009] Preferably, the connecting assembly includes a front toothed plate fixedly installed at the bottom of the connecting plate, a connecting gear meshing on the surface of the front toothed plate, an installation shaft fixedly installed inside the connecting gear, and fixed seats mounted on both the upper and lower ends of the installation shaft via bearings. The fixed seats are fixedly installed inside the mounting housing. A rear toothed plate meshing on the surface of the connecting gear is fixedly installed at the bottom of the right mold.
[0010] Preferably, the rear toothed plate and the front toothed plate have the same specifications, both of which are made of metal, and a rectangular groove for sliding the front toothed plate and the rear toothed plate is provided through the top of the mounting housing.
[0011] Preferably, the bending assembly includes a hydraulic push rod fixedly installed on the top of the mounting frame, a bending head fixedly provided at the output end of the hydraulic push rod, a guide rod fixedly provided at the top of the bending head, and a second linear bearing slidably provided on the surface of the guide rod, the second linear bearing being fixedly installed inside the mounting frame.
[0012] Preferably, a mounting vertical plate is fixedly installed on the top of the mounting base, a linear bearing is fixedly installed inside the mounting vertical plate, a limit rod is slidably installed inside the linear bearing, and there are several limit rods, which are respectively fixedly installed on the left side of the left mold and the right side of the right mold, and a limit plate is fixedly installed at the end of the limit rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The pre-bending equipment for washing machine production drives the left mold to move through the lateral moving component, and the left mold drives the right mold to move through the connecting component, so that the left mold and the right mold move in opposite directions at the same speed, and the distance moved by the left mold and the right mold remains the same. This allows the left mold and the right mold to be adjusted at one time, avoiding the need to adjust the left mold and the right mold separately, which would cause errors in the left mold and the right mold, resulting in uneven stress on the sheet metal during bending, and causing angle deviation, wrinkles or cracks.

[0016] 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.
[0017] Example: Refer to Figure 1-4A pre-bending device for washing machine production includes a mounting base 1, a mounting housing 2 fixedly mounted on the top of the mounting base 1, a lateral moving component disposed on the front side of the mounting housing 2, a left mold 9 and a right mold 15 overlapping each other on the top of the mounting housing 2, a connecting component disposed between the bottom of the left mold 9 and the bottom of the right mold 15, a mounting bracket 20 fixedly mounted on the top of the mounting base 1, a bending component disposed on the surface of the mounting bracket 20, and a connecting housing 3 fixedly mounted on the front side of the mounting base 1, a sliding groove 4 penetrating the top of the connecting housing 3, and a stepper motor fixedly mounted on the left side of the connecting housing 3. The stepper motor 5 has a lead screw 6 fixedly mounted at its output end. A threaded sleeve 7 is threaded onto the surface of the lead screw 6. A connecting plate 8 is fixedly mounted on the top of the threaded sleeve 7. The connecting plate 8 has an L-shaped structure and is made of metal. The side of the connecting plate 8 furthest from the threaded sleeve 7 is fixedly mounted on the front side of the left mold 9. The connecting plate 8 is slidably mounted inside the sliding groove 4. The connecting assembly includes a front gear plate 10 fixedly mounted at the bottom of the connecting plate 8. A connecting gear 11 is meshed on the surface of the front gear plate 10. A mounting shaft 12 is fixedly mounted inside the connecting gear 11. Both ends of the mounting shaft 12 are mounted with fixed seats 1 via bearings. 3. The fixed base 13 is fixedly installed inside the mounting housing 2. A rear gear plate 14 is meshed on the surface of the connecting gear 11. The rear gear plate 14 and the front gear plate 10 have the same specifications. Both the rear gear plate 14 and the front gear plate 10 are made of metal. A rectangular slide groove is provided through the top of the mounting housing 2 for the front gear plate 10 and the rear gear plate 14 to slide, so that the rear gear plate 14 and the front gear plate 10 move at the same distance. Moreover, the metal rear gear plate 14 and the front gear plate 10 are not easily damaged. The rear gear plate 14 is fixedly installed at the bottom of the right mold 15. The stepper motor 5 drives the lead screw 6 to drive the lead sleeve 7. When the connecting plate 8 moves, the left mold 9 drives the front toothed plate 10 to move, which in turn pushes the rear toothed plate 14 to move through the connecting gear 11. This causes the left mold 9 and the right mold 15 to move in opposite directions at the same speed, adjusting the distance between them. This ensures that the left mold 9 and the right mold 15 move the same distance, allowing them to be adjusted in one go. This avoids the need to adjust the left mold 9 and the right mold 15 separately, which could lead to errors in the left mold 9 and the right mold 15, resulting in uneven stress on the sheet metal during bending, causing angle deviations, wrinkles, or cracks.
[0018] Specifically, the bending assembly includes a hydraulic push rod 21 fixedly installed on the top of the mounting frame 20. A bending head 22 is fixedly installed at the output end of the hydraulic push rod 21. A guide rod 23 is fixedly installed on the top of the bending head 22. A linear bearing 24 is slidably installed on the surface of the guide rod 23. The linear bearing 24 is fixedly installed inside the mounting frame 20. The washing machine material is placed on the top of the left mold 9 and the right mold 15. The output end of the hydraulic push rod 21 drives the bending head 22 to move downward. The bending head 22 drives the guide rod 23 to slide inside the linear bearing 24, so that the bending head 22 cooperates with the left mold 9 and the right mold 15 to bend the washing machine material.
[0019] Specifically, a mounting vertical plate 16 is fixedly installed on the top of the mounting base 1. A linear bearing 18 is fixedly installed inside the mounting vertical plate 16. A limit rod 17 is slidably installed inside the linear bearing 18. There are several limit rods 17, which are respectively fixedly installed on the left side of the left mold 9 and the right side of the right mold 15. A limit plate 19 is fixedly installed at the end of the limit rod 17. During the movement of the left mold 9 and the right mold 15, the left mold 9 and the right mold 15 respectively drive the limit rod 17 to slide inside the linear bearing 18, so that the limit rod 17 and the linear bearing 18 guide the left mold 9 and the right mold 15, so that the left mold 9 and the right mold 15 keep moving in a straight line, so that the left mold 9 and the right mold 15 will not tilt during the movement, thereby avoiding the breakage of the connection between the left mold 9 and the right mold 15 and the front tooth plate 10 and the rear tooth plate 14 due to the tilting of the left mold 9 and the right mold 15.
[0020] In use: According to the material bending requirements in the washing machine production process, the stepper motor 5 drives the output end to rotate the lead screw 6, and the lead screw 6 drives the lead sleeve 7 to move the connecting plate 8. This causes the connecting plate 8 to move the left mold 9 on the top of the mounting shell 2. The left mold 9 then drives the front gear plate 10 to move, which in turn pushes the connecting gear 11 to rotate. The connecting gear 11 then drives the mounting shaft 12 to rotate inside the fixed seat 13 through the bearing. This causes the connecting gear 11 to push the rear gear plate 14 to move, and the rear gear plate 14 then drives the right mold 15 to move. This allows the left mold 9 and the right mold 15 to move in opposite directions at the same speed, thus adjusting the distance between the left mold 9 and the right mold 15.
[0021] Although embodiments of the present invention have been shown and described, 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.
