Description

Technical Field

[0001] This utility model relates to the field of refrigerator parts processing technology, specifically a bending device for processing refrigerator parts. Background Technology

[0002] In the refrigerator manufacturing process, the bending of rectangular parts (such as side panels and partitions) is one of the key processes. The bending accuracy and processing safety directly affect the assembly quality and production efficiency of the refrigerator.

[0003] Currently, existing bending equipment often encounters the following problems when processing rectangular parts for refrigerators:

[0004] When the bending cutter moves up and down under the drive of the hydraulic cylinder, it is prone to deviation due to the lack of a precise guiding structure, resulting in deviation of the bending position of the parts and affecting the subsequent assembly accuracy. During the bending process, the corners of the parts may generate debris and fly away. Existing equipment often lacks an effective protection mechanism, which can easily cause injury to operators. Different specifications of refrigerator parts require different sizes of bending cutters and lower dies, but the process of changing the bending cutter and lower die of traditional equipment is complicated and difficult to flexibly adapt to various processing needs, resulting in poor equipment versatility.

[0005] According to the description in the patent announcement (CN220942717U) of a bending device for processing refrigerator parts, the bending device includes a "base, worktable" etc., to realize the bending work.

[0006] Regarding the above description, the applicant believes the following issues exist:

[0007] This bending equipment for processing refrigerator parts utilizes a base and worktable to perform bending operations. During operation, the bending die is held in place by a second magnet. Simultaneously, rotating the nuts on the left, right, front, and back sides moves the rotating shaft, causing the suction cups to hold the bending die in place. However, this method of fixing cannot guarantee the stability of the bending die, and due to its weight, the die is prone to falling during bending, affecting bending safety. Therefore, improvements to this equipment are necessary. Utility Model Content

[0008] The purpose of this invention is to provide a bending device for processing refrigerator parts, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a bending device for processing refrigerator parts, comprising a processing table, a bending mechanism being provided on the top of the processing table, and a placement mechanism being provided on the top of the processing table;

[0010] The bending mechanism includes a fixed frame, which is fixedly connected to the top of the processing table. A side plate is fixedly connected to the left side of the fixed frame. A hydraulic cylinder is fixedly connected to the top of the fixed frame. A connecting seat is fixedly connected to the bottom of the hydraulic cylinder. A bending knife is connected to the bottom of the connecting seat. A connecting arm is slidably connected inside the connecting seat. The rear end of the bottom of the connecting arm is slidably connected to the inside of the bending knife. A fixed shaft is threaded inside the connecting arm. A support frame is fixedly connected to the front top of the fixed frame. A servo motor is fixedly connected to the left side of the support frame. A rotating rod is fixedly connected to the right side of the servo motor. A protective plate is fixedly connected to the periphery of the rotating rod.

[0011] Preferably, the side plate is fixedly connected to the top of the processing table, and there are two sets of side plates. The two sets of side plates are symmetrically distributed on the left and right sides inside the fixed frame. A guide frame is fixedly connected to the top of the connecting seat. The guide frame is slidably connected inside the fixed frame, which facilitates sealing and protection of the left and right sides of the fixed frame through the side plates.

[0012] Preferably, the top of the bending blade is in contact with the bottom of the connecting seat, and the fixed shaft passes through the inside of the connecting seat, so as to ensure the stability between the connecting arm and the connecting seat through the fixed shaft.

[0013] Preferably, the rotating rod is rotatably connected inside the support frame, and the protective plate is located on the front side of the fixed frame, so that the protective plate can be driven to work by the rotating rod.

[0014] Preferably, the support frame, servo motor, rotating rod and protective plate are provided in two sets and are symmetrically distributed on the front and rear sides of the fixed frame. Both sets of protective plates are transparent, which facilitates the sealing of the processing areas in front of and behind the fixed frame.

[0015] Preferably, the placement mechanism includes a mounting base, which is fixedly connected to the top of the processing table. A lower die is inserted into the top of the mounting base, and the lower die is disposed at the bottom of the bending knife. A limit shaft is threadedly connected inside the mounting base.

[0016] Preferably, the top of the lower die is slidably connected to the bottom of the bending knife, and the limiting shaft passes through the bottom end of the lower die, which facilitates the placement of the rectangular parts to be processed through the lower die.

[0017] Compared with the prior art, this utility model provides a bending device for processing refrigerator parts, which has the following beneficial effects:

[0018] 1. This bending equipment for refrigerator parts processing, through its bending mechanism, allows for precise guidance when bending rectangular refrigerator parts. The guide frame at the top of the connecting seat is slidably connected to the inside of the fixed frame, providing accurate guidance as the hydraulic cylinder drives the bending blade up and down, preventing blade deviation and ensuring accurate bending of the rectangular parts. The symmetrically arranged support frames, servo motors, rotating rods, and protective plates on the front and rear sides of the fixed frame constitute a protective structure. The transparent protective plate can be quickly closed during processing via the servo motor-driven rotating rod, effectively blocking potentially flying debris during bending, protecting operators from injury, and not obstructing observation of the processing. This avoids the problem of flying debris from corners during bending, improving operational safety. The bending blade and connecting seat are detachably connected via a connecting arm and a fixed shaft; different specifications of bending blades can be quickly replaced simply by loosening the fixed shaft, making operation convenient.

[0019] 2. The bending equipment for processing refrigerator parts has a set placement mechanism. The lower die is inserted into the mounting base and fixed by the limiting shaft. This makes it easy to change the corresponding lower die according to the rectangular parts of different sizes. It can flexibly adapt to rectangular parts of various specifications and different bending requirements without replacing the entire set of equipment, which greatly improves the versatility and applicability of the equipment.

[0031] This utility model provides the following technical solution:

[0032] Example 1

[0033] Please see Figure 1-7 This utility model provides a technical solution: a bending device for processing refrigerator parts, including a processing table 1, a bending mechanism 2 provided on the top of the processing table 1, and a placement mechanism 3 provided on the top of the processing table 1;

[0034] The bending mechanism 2 includes a fixed frame 21, which is fixedly connected to the top of the processing table 1. A side plate 23 is fixedly connected to the left side of the fixed frame 21. A hydraulic cylinder 22 is fixedly connected to the top of the fixed frame 21. A connecting seat 26 is fixedly connected to the bottom of the hydraulic cylinder 22. A bending knife 27 is connected to the bottom of the connecting seat 26. A connecting arm 28 is slidably connected inside the connecting seat 26. The rear side of the bottom end of the connecting arm 28 is slidably connected to the inside of the bending knife 27. A fixed shaft 29 is threadedly connected inside the connecting arm 28. A support frame 24 is fixedly connected to the front top of the fixed frame 21. A servo motor 292 is fixedly connected to the left side of the support frame 24. A rotating rod 291 is fixedly connected to the right side of the servo motor 292. A protective plate 293 is fixedly connected to the periphery of the rotating rod 291.

[0035] The side plate 23 is fixedly connected to the top of the processing table 1, and there are two sets of side plates 23. The two sets of side plates 23 are symmetrically distributed on the left and right sides inside the fixed frame 21. The top of the connecting seat 26 is fixedly connected to the guide frame 25, which is slidably connected to the inside of the fixed frame 21, so as to facilitate the sealing and protection of the left and right sides of the fixed frame 21 through the side plate 23.

[0036] The top of the bending blade 27 is in contact with the bottom of the connecting seat 26, and the fixed shaft 29 passes through the inside of the connecting seat 26, so as to ensure the stability between the connecting arm 28 and the connecting seat 26 through the fixed shaft 29.

[0037] The rotating rod 291 is rotatably connected to the inside of the support frame 24, and the protective plate 293 is located on the front side of the fixed frame 21, so that the protective plate 293 can be driven to work by the rotating rod 291.

[0038] The support frame 24, servo motor 292, rotating rod 291 and protective plate 293 are provided in two sets and are symmetrically distributed on the front and rear sides of the fixed frame 21. Both sets of protective plates 293 are transparent, which facilitates the sealing of the processing area in front of and behind the fixed frame 21.

[0039] Example 2

[0040] Please see Figure 1-7 Furthermore, based on Embodiment 1, the placement mechanism 3 includes a mounting base 31, which is fixedly connected to the top of the processing table 1. A lower die 32 is inserted into the top of the mounting base 31, and the lower die 32 is located at the bottom of the bending knife 27. A limit shaft 33 is threadedly connected inside the mounting base 31.

[0041] The top of the lower die 32 is slidably connected to the bottom of the bending knife 27, and the limiting shaft 33 passes through the bottom of the lower die 32, which facilitates the placement of rectangular parts that need to be processed through the lower die 32.

[0042] In actual operation, when this device is used, when it is necessary to bend rectangular parts of the refrigerator, firstly, the bending blade 27 and the lower die 32 are replaced according to the size of the part to be bent and the shape to be bent. First, the lower die 32 is inserted into the top of the mounting base 31 and fixed by the limiting shaft 33. At the same time, the matching bending blade 27 is placed in the middle of the top of the lower die 32. The hydraulic cylinder 22 drives the connecting seat 26 to move so that the moving seat is on the top of the bending blade 27. At this time, the connecting arm 28 can be slidably connected to the connecting seat 26 and the bending blade 27. The connecting arm 28 and the connecting seat 26 are fixed by the fixing shaft 29, which can fix the bending blade 27. At the same time, under the action of the hydraulic cylinder 22, the bending blade 27 is moved away from the top of the lower die 32. The part to be bent is placed on the top of the lower die 32, and the edge of the part is held.

[0043] The hydraulic cylinder 22 drives the connecting seat 26 and the bending knife 27 to move, and the connecting seat 26 drives the guide frame 25 to slide inside the fixed frame 21. When the bending knife 27 contacts the part and the part is in a stable state, the operator can drive the protective plate 293 fixedly connected to the outer side of the rotating rod 291 to rotate through the servo motor 292. This can protect the front and rear sides of the fixed frame 21, effectively blocking the debris that may fly during the bending process and protecting the operator from injury, without affecting the observation of the processing process. This avoids the problem of corner debris flying during bending and improves the safety of operation.

[0044] After bending is completed, the staff needs to clean the debris on the top of the lower die 32 regularly to ensure the quality of subsequent bending. The bending blade 27 and the connecting seat 26 are detachably connected through the connecting arm 28 and the fixed shaft 29. Different specifications of bending blades 27 can be quickly replaced by simply loosening the fixed shaft 29, which is convenient to operate. The lower die 32 is inserted into the mounting seat 31 and fixed by the limiting shaft 33, which makes it easy to replace the corresponding lower die 32 according to the rectangular parts of different sizes. It can flexibly adapt to rectangular parts of various specifications and different bending requirements without replacing the entire set of equipment, which greatly improves the versatility and applicability of the equipment.

[0045] In this application, the hydraulic cylinder 22 and two sets of servo motors 292 need to be connected to a PLC controller near the equipment to ensure automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method. This application will not describe it in detail.
