Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal bending device. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by the sheet metal industry are called sheet metal parts.

[0003] Chinese Patent Publication No. CN218395420U discloses a sheet metal bending device, including a base frame. Two support plates are fixedly connected to the top side of the base frame. Each of the two support plates has a cavity inside. A motor is fixedly connected to the bottom inner wall of the base frame. Two reciprocating screws are rotatably connected to the bottom inner wall of the base frame. The two reciprocating screws are rotatably connected to the two support plates respectively. A sprocket is fixedly sleeved on the output shaft of the motor and the outer side of the two reciprocating screws. The outer sides of the three sprockets are meshed with the same chain. The outer sides of the two reciprocating screws are helically driven with thread sleeves. The two thread sleeves are fixedly connected to the same pressure plate. An upper module is fixedly installed on the bottom side of the pressure plate, and a lower module is fixedly installed on the top side of the base frame.

[0004] In this existing design, although a reciprocating screw can be set up and a motor can generate driving force, when the reciprocating screw rotates continuously, it can drive the upper module to move up and down back and forth, and then cooperate with the lower module to complete the bending of the sheet metal part. Compared with the comparison document, it can avoid the motor constantly reversing, thus effectively reducing the wear rate of the parts and the loss of potential energy. It can also effectively improve the service life and reduce production costs. By setting a top block, after the upper module cooperates with the lower module to bend the sheet metal part, the top block can lift the bent sheet metal part, making it easier for workers to remove the bent sheet metal part. However, metal chips and small fragments are inevitably generated during the processing. Traditional bending devices often require manual cleaning of processing waste, which increases labor consumption.

[0005] Therefore, a sheet metal bending device is designed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the technical problems mentioned in the background section.

[0007] This utility model adopts the following technical solution: a sheet metal bending device, including a processing base, a column fixedly installed on the top surface of the processing base, a cylinder fixedly installed on the top surface of the column, a bending block installed at the output end of the cylinder, a bending seat fixedly installed on the top surface of the processing base, a cavity opened inside the processing base, a slide rod fixedly installed inside the cavity, a moving plate slidably connected to the surface of the slide rod, a groove opened on the top surface of the processing base, a scraper fixedly installed on the top surface of the moving plate, a motor fixedly installed inside the cavity, and a lead screw installed at the output end of the motor.

[0008] As a preferred embodiment of the sheet metal bending device of this utility model, the inner wall of the column is provided with a guide groove, and guide blocks are fixedly installed on both sides of the bending block. The guide blocks are located inside the guide groove and are slidably connected to the guide groove.

[0009] As a preferred embodiment of the sheet metal bending device of this utility model, a baffle is fixedly installed on the back of the column, and the baffle is made of PVC plastic.

[0010] As a preferred embodiment of the sheet metal bending device of this utility model, the number of scrapers is two sets, and the two sets of scrapers are symmetrically distributed on both sides of the bending seat.

[0011] In a preferred embodiment of the sheet metal bending device of this utility model, the bottom surface of the scraper is in contact with the top surface of the processing seat.

[0012] As a preferred embodiment of the sheet metal bending device of this utility model, the lead screw passes through the interior of the moving plate, and the interior of the moving plate is provided with threads, and the threads are engaged with the lead screw.

[0013] As a preferred embodiment of the sheet metal bending device of this utility model, an elastic strip is fixedly installed on the top surface of the slide groove.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model is equipped with a lead screw, a slide bar, a moving plate, a scraper, and a motor, which can clean the processing waste on the top surface of the processing seat. Simply start the motor, and the motor will drive the lead screw to rotate. The lead screw will drive the moving plate to move, and the moving plate will then drive the scraper to clean the top surface of the processing seat. This makes it easy to collect metal shavings and small fragments generated during bending, keep the working area clean, and reduce the cleaning workload of the workers.

[0016] 2. In this utility model, a baffle and an elastic strip are provided. The baffle can block the metal chips and small fragments generated during the bending process, preventing the processing waste from splashing and being difficult to clean. The elastic strip is set on the top surface of the slide groove, which can block the processing waste and prevent it from affecting the movement of the scraper. At the same time, it can also prevent the processing waste from entering the slide groove to a certain extent. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example

[0026] Please see Figure 1-Figure 4This utility model provides a technical solution: a sheet metal bending device, including a processing base 1, a column 2 fixedly installed on the top surface of the processing base 1, the column 2 supporting a cylinder 3, and a baffle 15 fixedly installed on the back of the column 2. The baffle 15 is made of PVC plastic, which is transparent and can shield processing waste while preventing observation of the processing from the back of the device. The baffle 15 also shields against flying waste during processing, preventing accidents caused by flying waste. A guide groove 13 is provided on the inner wall of the column 2. A cylinder 3 is fixedly installed on the top surface of column 2. A bending block 4 is installed at the output end of cylinder 3. Guide blocks 14 are fixedly installed on both sides of bending block 4. The guide blocks 14 are located inside guide groove 13 and are slidably connected to guide groove 13. Guide groove 13 and guide blocks 14 can guide the movement trajectory of bending block 4, preventing bending block 4 from shaking during processing and affecting processing. At the same time, it can also improve the processing stability of bending block 4. A bending seat 5 is fixedly installed on the top surface of processing seat 1. A cavity 6 is opened inside processing seat 1. A bending seat 5 is fixedly installed inside the cavity 6. A sliding rod 7 is provided, and a movable plate 8 is slidably connected to the surface of the sliding rod 7. A groove 9 is provided on the top surface of the processing seat 1, and an elastic strip 16 is fixedly installed on the top surface of the groove 9. The elastic strip 16 is made of organic silicone, which has good tensile strength. It facilitates the movement of the scraper 10 and can also cover the groove 9 to prevent processing waste from entering the cavity 6 and affecting its use. A scraper 10 is fixedly installed on the top surface of the movable plate 8. There are two sets of scrapers 10, which are symmetrically distributed on both sides of the bending seat 5. The bottom surface of the scraper 10 is in contact with the top surface of the processing seat 1 to facilitate scraping. Plate 10 cleans the machining waste generated on the top surface of machining seat 1. A motor 11 is fixedly installed inside the cavity 6. A lead screw 12 is installed at the output end of the motor 11. One end of the lead screw 12 is rotatably connected to the inner wall of the cavity 6, which can limit the lead screw 12 and prevent the lead screw 12 from rotating on its own. The lead screw 12 passes through the interior of the movable plate 8. The interior of the movable plate 8 is threaded, and the thread meshes with the lead screw 12, so that the movable plate 8 can be moved when the lead screw 12 rotates, thereby cleaning the machining waste on the top surface of machining seat 1 by scraper 10.

[0027] Working principle: In use, the sheet metal part to be processed is placed on the top surface of the bending seat 5. Then, the cylinder 3 is started, which drives the bending block 4 to move. At the same time, the bending block 4 drives the guide block 14 to slide inside the guide groove 13 until the bending block 4 bends the sheet metal part. When it is necessary to clean up the processing waste, the motor 11 is activated. The motor 11 drives the lead screw 12 to rotate. Since one end of the lead screw 12 is rotatably connected to the inner wall of the cavity 6, and the lead screw 12 passes through the interior of the moving plate 8, ... The movable plate 8 has a thread inside that meshes with the lead screw 12. When the lead screw 12 rotates, it drives the movable plate 8 to move. At this time, the movable plate 8 slides on the surface of the slide bar 7. Simultaneously, the movable plate 8 drives the scraper 10 on its top surface to slide in the slide groove 9. Since the bottom surface of the scraper 10 is in contact with the top surface of the processing seat 1, the scraper 10 immediately cleans the processing waste on the top surface of the processing seat 1. This reduces the cleaning workload of the staff to a certain extent, makes it easier to clean the top surface of the processing seat 1, and avoids affecting its use.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
