Description

Technical Field

[0001] The present application relates to the technical field of bending equipment, and particularly relates to a continuous bending device for sheet metal processing. Background Art

[0002] Sheet metal is a comprehensive cold working process for metal sheets, including shearing, punching / cutting / combining, bending, welding, riveting, splicing, forming, etc. Its remarkable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. When performing bending processing on sheet metal parts, a bending device is required. After retrieval, the patent document with the authorization announcement number CN217889139U discloses a bending device for sheet metal processing, which includes a workbench. A bending groove is opened on the upper end surface of the workbench. A bending head adapted to the bending groove is arranged directly above the bending groove. A hydraulic cylinder is installed at the upper end of the bending head. The outer wall of the output end of the hydraulic cylinder is slidably connected with a fixing frame. The upper end of the hydraulic cylinder is fixedly connected with the upper end of the fixing frame. The fixing frame is in a U-shaped structure with an opening downward, and the lower ends of the front and rear ends of the fixing frame are connected to the existing ground. A limiting mechanism is arranged on the upper end of the workbench; this solution can realize the bending function of sheet metal parts through the bending groove, the bending head and the hydraulic cylinder. The workbench can be used to horizontally place multiple sheet metal parts, and the limiting mechanism can realize the function of synchronously limiting multiple sheet metal parts, so as to prevent the sheet metal parts from shifting during the bending process, thereby ensuring the bending effect of the sheet metal parts.

[0003] The above-mentioned related solutions are still found to have at least the following deficiencies in actual operation: Although it can meet the basic requirement of simultaneously bending multiple sheet metal blanks, before bending multiple sheet metal blanks, it is necessary to manually operate to neatly arrange multiple sheet metal blanks on the workbench and manually operate to limit multiple sheet metal blanks, and then bending processing can be carried out. After the processing is completed, it is also necessary to manually operate to disassemble and remove the bent sheet metal blanks before continuing to bend other sheet metal parts. This bending processing method is cumbersome, time-consuming and laborious when bending a large number of sheet metal blanks, with low work efficiency, and cannot meet the requirement of continuous bending processing of a batch of sheet metal blanks. Therefore, we propose a continuous bending device for sheet metal processing to solve the above problems. Summary of the Utility Model

A motor 19 is fixedly installed on the front outer wall of the machine table 1, and the output shaft end of the motor 19 is fixedly connected to the front end of one of the conveying rollers 3, wherein:

[0027] A bearing seat 4 is detachably fixedly installed on the inner wall at the bottom of the conveying trough 2. The top surface of the bearing seat 4 is flush with the top of the conveying roller 3. The bearing seat 4 is located between the two conveying rollers 3 on the right. A bending groove is opened on the top of the bearing seat 4. An L-shaped frame 5 is fixedly installed on the top of the machine table 1. An electric hydraulic cylinder 6 is fixedly installed on the top of the L-shaped frame 5. A mounting plate 7 is fixedly installed on the output shaft end of the electric hydraulic cylinder 6. A bending head 8 is detachably fixedly installed on the bottom of the mounting plate 7. The bending head 8 is located just above the bending groove. The pressure cylinder 6 is used to control the vertical movement of the mounting plate 7 and the bending head 8.

The conveying trough 2 is provided with a pushing mechanism for pushing out the sheet metal blank, and the pushing mechanism is located between the guiding mechanism and the positioning mechanism.

[0028] In this embodiment, it should be noted that both the bearing seat 4 and the bending head 8 can be installed and fixed in the direction of bolt assembly and fixing, thereby facilitating the disassembly and assembly of the bearing seat 4 and the bending head 8 for replacement or maintenance.

[0029] In this embodiment, the guiding mechanism includes two first electric telescopic rods 9 and two limit plates 10. The two first electric telescopic rods 9 are fixedly mounted on the top front side and the top rear side of the machine platform 1. The two first electric telescopic rods 9 are symmetrically distributed. The two limit plates 10 are respectively fixedly mounted on the output shaft ends of the corresponding first electric telescopic rods 9. The two limit plates 10 are both located above the conveying roller 3. The first electric telescopic rod 9 can be used to control the limit plates 10 to move horizontally and linearly. The two limit plates 10 can be used to block the sheet metal blanks conveyed on the multiple conveying rollers 3. The stop limit can keep the sheet metal blank moving horizontally and linearly on multiple conveying rollers 3. The above-mentioned positioning mechanism includes an electric guide rail 11, an electric slide 12 and a vertical baffle 13. It should be noted that the sides of the two limit plates 10 that are close to each other are both smooth planes. The electric guide rail 11 is fixedly installed on the bottom inner wall of the conveying trough 2, and the electric slide 12 is slidably installed on the electric guide rail 11. The vertical baffle 13 is fixedly installed on the top of the electric slide 12, and the top of the vertical baffle 13 extends to the outside of the conveying trough 2. The vertical baffle 13 can be used to adjust the position of the conveyed sheet metal blank Blocking positioning, without changing the position of the vertical baffle 13, when a large number of sheet metal blanks of the same model are continuously bent, the bending position of each sheet metal blank can be guaranteed to be consistent. The electric slide 12 is connected and matched with the electric guide rail 11 to adjust the position of the vertical baffle 13 in the horizontal direction, that is, to change the spacing between the vertical baffle 13 and the bending head 8, so as to facilitate bending of different parts of the sheet metal blank according to needs. The above-mentioned pushing mechanism includes a second electric telescopic rod 15 and a pushing plate 16. The second electric telescopic rod 15 is fixedly mounted on the rear inner wall of the conveying trough 2 and is located between the bearing seat 4 and the bending head 8. The push plate 16 is fixedly mounted on the output shaft end of the second electric telescopic rod 15. A discharge port 17 is provided on the front inner wall of the conveying trough 2 and is located directly in front of the bearing seat 4. The top of the discharge port 17 is an open structure. The push plate 16 can be controlled to move horizontally and linearly by the second electric telescopic rod 15. The push plate 16 can be used to push the bent sheet metal blank out of the machine 1 from the discharge port 17 without manual material removal, so as to facilitate continuous bending of large quantities of sheet metal parts.

[0030] In this embodiment, the vertical spacing between the bottom of the limiting plate 10 and the top of the conveying roller 3 is 0.5-1 mm, so that the bottom of the limiting plate 10 and the conveying roller 3 produce contact friction, and can ensure that the sheet metal blank will not enter or get stuck in the gap between the limiting plate 10 and the conveying roller 3.

[0031] In this embodiment, a scale 14 is fixedly mounted on the rear side wall of the vertical baffle 13 , and the scale 14 is located directly behind the bending head 8 , so as to facilitate observation and calculation of the vertical distance between the vertical baffle 13 and the bending head 8 .

[0032] In this embodiment, the outer surfaces of the plurality of conveying rollers 3 are all provided with anti-slip grooves, which can increase the friction force when the sheet metal blank contacts the conveying rollers 3, and can more smoothly convey the sheet metal blank horizontally and linearly.

[0033] In the present embodiment, it should be noted that the electric hydraulic cylinder 6, the first electric telescopic rod 9, the second electric telescopic rod 15, the electric guide rail 11, the electric slide 12 and the motor 19 can be purchased on the market, and the electric hydraulic cylinder 6, the first electric telescopic rod 9, the second electric telescopic rod 15, the electric guide rail 11, the electric slide 12 and the motor 19 are equipped with a power supply, and their line connection method and control method are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0034] Through the above structure, the continuous bending device for sheet metal processing provided by the present application can continuously bend a large number of sheet metal blanks of the same model when in use, and can ensure that the bending position of each sheet metal blank is consistent, thereby reducing the operation steps and manual labor, saving working time, and improving working efficiency. In specific operation, by controlling the two first electric telescopic rods 9 to extend and operate, the two limit plates 10 can be moved in a direction close to each other, and by controlling the two first electric telescopic rods 9 to retract and reset, the two limit plates 10 can be moved in a direction away from each other, thereby facilitating the adjustment of the spacing between the two limit plates 10. According to the width of the sheet metal blank, the spacing between the two limit plates 10 can be adjusted to be slightly larger than the width of the sheet metal blank;

[0035] By controlling the horizontal linear sliding of the electric slide 12 on the electric guide rail 11, the electric slide 12 can drive the vertical baffle 13 to move horizontally, so as to change the spacing between the vertical baffle 13 and the bending head 8. By observing the scale on the scale 14, it can be known that the spacing between the vertical baffle 13 and the bending head 8 is vertical, so as to facilitate adjusting the spacing between the vertical baffle 13 and the bending head 8 to the desired spacing size.

[0036] After adjusting the spacing between the two limit plates 10 and the position of the vertical baffle 13, by controlling the operation of the motor 19, under the transmission action of multiple sets of chain transmission parts, multiple conveying rollers 3 can be controlled to rotate synchronously in the same direction (from the main viewing angle, multiple conveying rollers 3 rotate clockwise at the same time), so that batches of sheet metal blanks can be continuously conveyed. During the conveying process, the two limit plates 10 are used to cooperate with each other to guide the moving direction of the sheet metal blank so that the sheet metal blank maintains a straight line movement from left to right. When the sheet metal blank on the far right moves to the position that conflicts with the vertical baffle 13 (a Hall sensor or photoelectric switch purchased on the market can be installed on the vertical baffle 13 to be electrically connected to the motor 19. When the sheet metal blank conflicts with the vertical baffle 13, the motor 19 can be immediately controlled to stop running), the motor 19 is stopped, and then the electric hydraulic cylinder 6 is controlled to extend and run, so that the sheet metal blank can be controlled to stop running. The mounting plate 7 and the bending head 8 are controlled to move vertically downward, and the bending head 8 is used to apply a vertical downward force to the sheet metal blank and cooperate with the use of the bending groove to be bent to the sheet metal blank. After the bending is completed, the electric hydraulic cylinder 6 is controlled to retract and reset, so that the mounting plate 7 and the bending head 8 can be moved vertically upward and returned to their positions, and then the second electric telescopic rod 15 is controlled to extend and operate, and the push plate 16 can be used to push the bent sheet metal blank out of the discharge port 17. After being pushed out, the second electric telescopic rod 15 is controlled to retract and reset so that the push plate 16 returns to its position, and then the motor 19 is continued to be controlled to operate, so that the sheet metal blank can continue to be conveyed from left to right. According to the above-mentioned operating steps, batches of sheet metal blanks can be bent one by one, thereby reducing the steps of manually taking and placing sheet metal blanks, saving working time and labor, and being able to achieve the effect of continuous bending processing of batches of sheet metal blanks.
