Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, and more specifically, to a positioning device for double-edge bending processing of a bending machine. Background Art

[0002] With the continuous development of the power industry, China is still vigorously promoting the construction of strong power grids on a large scale and continuously updating and replacing the development of the industry on a large scale. Most of the high- and low-voltage cabinet frameworks used in power stations, distribution rooms, and integrated box transformers in the development of power grid construction are processed by the double-edge bending process. Because the finished products manufactured by this double-edge bending process are smooth without burrs and have higher strength than single-edge bending. High- and low-voltage cabinets such as HXGN, KYN28 produced in the past and KYN88 produced by the applicant all adopt this process. In addition to the electrical industry, there are also many products processed by the double-edge bending process in the household appliance industry, such as air conditioners, washing machines, cabinets, car doors, office cabinets, desks, etc. all adopt the double-edge bending process.

[0003] For currently produced high- and low-voltage cabinets, since the cabinet height is 2.2 meters, when double-edge bending and processing the side plate with a length of 2.2 meters, a huge horizontal force will be generated when compacting the workpiece at a 30° angle. This horizontal force will cause the workpiece to be processed to have a horizontal displacement. In order to ensure the quality of the edge bending processing, additional workers are required to hold it firmly during the edge bending processing, which is both laborious and poses a safety hazard.

[0004] Therefore, it is necessary to study a positioning device for double-edge bending of a bending machine to reduce labor intensity and improve labor efficiency, and it can also create good social and economic benefits for society. Content of the Utility Model

The side plates are used for fixing to the bracket, and the relief hole is formed in the top plate; the fixing seat is arranged below the top plate with a gap from the bracket and can move up and down relative to the top plate.

[0011] In one embodiment, the height of the gap is between 0.1 and 0.3 mm.

[0012] In one embodiment, elongated mounting holes are formed in the side plates for passing through threaded connectors to fix to the bracket.

[0013] In one embodiment, the positioning seat is formed by sheet metal processing.

[0029] Please refer to Figures 1 to 5, The utility model relates to a positioning device for double hemming processing of a bending machine (hereinafter referred to as "positioning device 100"), which is suitable for being installed on a workpiece bracket to limit the horizontal movement of a workpiece to be processed (such as a 30° angle plate 300), so as to reduce the labor intensity during hemming processing, improve the processing efficiency and ensure the processing quality.

[0030] The positioning device 100 includes a positioning seat 10 and a positioning pin 20. The positioning seat 10 is used to be fixed to the bracket 230 of the bending machine and support the workpiece to be processed from below. The positioning pin 20 is installed on the positioning seat 10 and is used to be inserted into a positioning hole pre-opened on the workpiece to be processed.

[0031] By setting the positioning seat 10 fixed to the bracket, and installing the positioning pin 20 on the positioning seat 10, the positioning pin 20 is inserted into the positioning hole of the workpiece to be processed during hemming processing, which can avoid the horizontal displacement of the workpiece to be processed under the action of horizontal force, thus ensuring the hemming processing quality, improving the processing efficiency, reducing the labor intensity of the operator and reducing the labor cost.

The fixing seat 30 is arranged below the top plate 12 with a gap from the bracket and can move up and down relative to the top plate 12.

[0035] In one implementation, the height of the gap is between 0.1 and 0.3 mm.

[0036] Thus, by setting a gap between the fixing seat 30 and the bracket, the fixing seat 30 can move up and down relative to the top plate 12 of the positioning seat 10, so that the positioning pin 20 can perform axial movement for a certain distance, avoiding the deformation of the pin under the downward pressure.

[0038] In one embodiment, at least two of the elongated mounting holes 111 are arranged along the height direction of the side plate 11 , which can improve the strength of the connection structure between the side plate 11 and the bracket 230 and also realize the adjustment of the height of the positioning pin shaft 20 .

[0039] In one embodiment, the positioning seat 10 and the fixing seat 30 are both formed by a sheet metal process and subjected to a surface electrostatic powder spraying process for rust prevention, thereby enhancing the structural strength of the positioning seat 10 and the fixing seat 30 and extending their service life.

[0040] In one embodiment, the locating pin 20 is welded to the fixing seat 30. In other embodiments, the locating pin 20 is inserted into the fixing seat 30 with a tight fit, or the locating pin 20 is threadedly fixed to the fixing seat 30 to facilitate replacement of the locating pin 20 when the locating pin 20 is deformed or adapted to the processing of panels of different sizes.

[0041] In one embodiment, the fixing seat 30 includes a fixing plate and folded edges formed by bending two sides of the fixing plate, and the positioning pin shaft 20 is fixed to the middle of the fixing plate.

[0042] In one embodiment, the fixing seat 30 includes a fixing plate and a folded edge formed by bending two sides of the fixing plate, the folded edge can be pressed against the bottom surface of the top plate 12 of the positioning seat 10, and the positioning pin shaft 20 is fixed to the middle of the fixing plate.

[0043] The working process of folding using the positioning device is as follows:

[0044] First, the positioning device is installed on the bracket 230 of the bending machine. Specifically, the fixing seat 30 is placed into the positioning seat 10 from the lower end opening of the positioning seat 10, and the positioning pin shaft 20 is inserted into the clearance hole 121 of the top plate 12 of the positioning seat 10, and then the bolts are inserted into the long strip mounting holes 111 of the side plate 11 of the positioning seat 10 to assemble with the bracket 230 of the bending machine, so as to fix the positioning device on the bracket.

[0045] Then, the 30° angle plate 300 is placed on the processing station of the bending machine (the corner end of the workpiece is placed between the upper die and the lower die), supported by the bracket 230, and the positioning pin shaft 20 is inserted into the positioning hole on the 30° angle plate.

[0046] Finally, start the bending machine, move the upper die 210 of the bending machine downward toward the lower die 220, press the 30° angle plate 300, and make the upper and lower sides of the 30° angle plate 300 fit together to complete the edge folding process.
