Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Figure 1 It is a top view of the present invention, and combined with Figure 2As shown, the sheet metal bending and forming processing equipment for the electrical control cabinet includes a workbench 1, a positioning component and a bending component. The upper end surface of the workbench 1 is provided with a liftable table plate 2, and a pad is fixed at the bottom end of the workbench 1, and the pad is used to contact the ground. The positioning component is installed on one side of the upper end surface of the table plate 2, and the positioning component is used to limit the position of the sheet metal to be bent. Among them, a plurality of third cylinders 12 are installed at the inner bottom of the workbench 1, and the table plate 2 is installed at the top of the third cylinder 12. The table plate 2 can be driven to move up and down by the third cylinder 12. When the equipment is used, the table plate 2 is moved up to be flush with the upper end surface of the workbench 1. When the equipment is not used, the table plate 2 can be moved down to the inside of the workbench 1, so that the structure installed on the upper end surface of the table plate 2 is retracted below the upper end surface of the workbench 1, and then a cover plate or a cloth is used to cover the upper end surface of the workbench 1 to reduce the occurrence of bumps and dust on the structure installed on the table plate 2.

[0022] See also Figure 1-Figure 2 As shown, the bending assembly includes a supporting part and a pushing part. The supporting part includes a supporting rod 14 that supports the bending part of the sheet metal. A plurality of embedding grooves 6 are provided on the upper end surface of the table plate 2 and along its length direction. The bottom end of the supporting rod 14 can be embedded in any embedding groove 6. The pushing part includes a driving member and an extrusion rod 8. The extrusion rod 8 is detachably installed at the output end of the driving member.

[0023] Through the above, by changing the position of the push rod 14 in different embedding grooves 6, the spacing between the push rod 14 and the positioning assembly can be changed, which is convenient for adjustment according to needs and more flexible.

[0024] Further, see Figure 1 and Figure 4 As shown, a protrusion 19 is fixed to the lower end of the outer wall of the support rod 14, and a mounting hole 18 is opened on the upper end surface of the table 2 and located next to the embedding groove 6. The protrusion 19 can be screwed through with a fastening screw 20, and the fastening screw 20 can be screwed into the mounting hole 18.

[0025] Specifically, after the push rod 14 is inserted into the embedding groove 6, the fastening screw 20 can be screwed through the protrusion 19 and then screwed into the corresponding mounting hole 18, which can effectively ensure the stability of the push rod 14 after insertion and prevent it from being removed at will.

[0026] In one embodiment of the present invention, refer to Figure 1 , Figure 3 and Figure 5 As shown, the driving member includes a first cylinder 7 and a support plate 10. The first cylinder 7 is installed on the upper end surface of the support plate 10, and a mounting block 15 is fixed to the output end of the first cylinder 7. A slot 16 is provided on the outer wall of the mounting block 15. An insert block 17 is fixed to the outer wall of the extrusion rod 8. The insert block 17 is inserted and matched with the slot 16.

[0027] As mentioned above, by starting the first air cylinder 7 , the movement of the squeezing rod 8 can be realized, and then the squeezing rod 8 can be used to squeeze the sheet metal part, so that the sheet metal part is bent at the position against the abutting rod 14 .

[0028] When installing the extrusion rod 8, the insert block 17 can be inserted along the slot 16, which is convenient and quick to install and is also convenient for replacing the extrusion rod 8. Secondly, the bottom end of the slot 16 is not through, which can prevent the extrusion rod 8 from moving down or contacting the table 2 after being inserted and installed to generate greater resistance.

[0029] In addition, see Figure 1-Figure 2 As shown, the lower end surface of the support plate 10 is connected with a slide bar 13, the upper end surface of the table plate 2 is provided with a slide groove 11, the slide bar 13 slides in the slide groove 11, and the upper end surface of the table plate 2 is also installed with a second cylinder 9, and the output end of the second cylinder 9 is connected to the support plate 10.

[0030] From above, start the second cylinder 9, and use the second cylinder 9 to drive the pallet 10 to move. The position of the first cylinder 7 on the pallet 10 can be changed by using the linear sliding of the slide bar 13 in the slide groove 11, so as to flexibly change the position of the extrusion rod 8 to push and bend the sheet metal parts.

[0031] In one embodiment of the present invention, refer to Figure 1 As shown, the positioning assembly includes two vertical plates 3, and the two vertical plates 3 are fixed in parallel to one side of the upper end surface of the table plate 2, and a sheet metal placement area is formed between the two vertical plates 3.

[0033] Through the above technical solution: When in use, the sheet metal to be bent can be placed in the sheet metal placement area between the two vertical plates 3, so that the bending area is against the support rod 14, and then the electric telescopic rod 4 is started, and the clamping plate 5 is driven to move by the electric telescopic rod 4. The clamping plate 5 can be used in conjunction with the vertical plates 3 to limit sheet metal parts of different thicknesses.

[0034] Among them, using the rubber pad to contact the sheet metal part can reduce the wear of the outer wall of the sheet metal part.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
