Detailed Description

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

As shown in fig. 1 to 5, an embodiment of the application provides a bending tool for sheet metal machining, which includes a bottom plate 1, a lower template 2 arranged at the top end of the bottom plate 1, and an upper template 3 arranged above the lower template 2; the upper template 3 is provided with a bending assembly, the outer surface of the upper end of the lower template 2 is provided with guide pillars 4 at positions close to two sides, a guide hole 5 is formed in the upper template 3, and the guide pillars 4 are inserted in the guide hole 5; a pressure groove 6 is formed in the middle of the outer surface of the upper end of the lower template 2, and an auxiliary assembly is arranged inside the pressure groove 6; the front end of the bottom plate 1 is provided with a level ruler 12, and the bottom end of the bottom plate 1 is provided with an adjusting column 15.

When the invention is used, the level ruler 12 is observed to know whether the tool is in a horizontal state, when the tool is found to be in a non-horizontal state, the horizontal state is adjusted through the adjusting column 15, the condition that the bending assembly is damaged due to the fact that the single side of the bending assembly is continuously stressed too much because the tool inclines is avoided, the tool is protected better, the service life of the tool is prolonged, after the adjustment is finished, the sheet metal part to be bent is placed on the auxiliary assembly in the pressure groove 6, then the sheet metal part to be bent is pressed downwards through the bending assembly arranged on the upper template 3, the sheet metal part to be bent is bent, through the arrangement, the bending operation of the sheet metal part can be rapidly carried out, the sheet metal processing requirement is met, meanwhile, the guide post 4 is inserted into the guide hole 5 to play a role in positioning, so that bending deviation is avoided.

The bending assembly comprises a lower pressing column 10 arranged at the top end of the upper template 3 and a pressing block 11 arranged at the bottom end of the upper template 3, and the lower pressing column 10 is connected with the pressing block 11 through a connecting assembly; a connecting column 101 comprising the bottom end of the lower pressing column 10 and a connecting pipe 111 at the top end of the pressing block 11 are connected, and the connecting column 101 is in threaded connection with the connecting pipe 111;

the setting that compression leg 10 and briquetting 11 are connected through coupling assembling down can be at briquetting 11 wearing and tearing too much time convenient to use person to its change, has reduced because the too much too big situation of bending of the formation that leads to of briquetting 11 wearing and tearing takes place, spliced pole 101 and the 111 threaded connection of connecting pipe let the user as long as rotatory compression leg 10 can be separated compression leg 10 and briquetting 11 with compression leg 11 down.

The auxiliary assembly comprises an auxiliary block 7, two protection columns 8 arranged at the bottom end of the auxiliary block 7 and a protection spring 9 arranged outside the protection columns 8, and the top end of each protection column 8 penetrates through the auxiliary block 7.

The sheet metal component that need bend is placed at auxiliary block 7, and when briquetting 11 pushed down, the sheet metal component of bending was hugged closely auxiliary block 7, and auxiliary block 7 is pressed and is sunken into indent 6 to the realization is bent the operation to the sheet metal component that needs bend, and the completion of bending is pushed up by protection spring 9 and is moved auxiliary block 7 and reset and carry out the operation of bending next time, has saved the trouble of manual reset for the efficiency of bending.

A return spring 41 is sleeved outside the guide post 4, and a limiting block 51 is arranged on the inner wall of the guide hole 5;

the reset spring 41 sleeved outside the guide post 4 is matched with the limit block 51 arranged on the inner wall of the guide hole 5, so that the upper die plate 3 can be reset in time to perform the next bending operation after the bending is finished, and the bending progress is accelerated.

The adjusting column 15 comprises a first column 151, a second column 152 screwed at the bottom end of the first column 151, and a bottom block 153 arranged at the bottom end of the second column 152.

The user has just rotated second cylinder 152 and has changed its length in first cylinder 151 and accomplished the purpose of adjusting the levelness promptly, has avoided because the condition emergence of the subassembly damage of bending that the unilateral continuous atress of subassembly that bends leads to greatly leads to of frock slope, better protection this frock, has prolonged the life of this frock.

The outer surface of the upper end of the lower template 2 is also provided with a positioning block 13, a plurality of positioning holes 14 are formed in the lower template 2, and the positioning block 13 is connected with the positioning holes 14 through screws.

The positioning block 13 plays a role in auxiliary positioning, so that bending errors caused by deviation of the bent sheet metal parts are avoided, and meanwhile, the positioning blocks 13 are installed by rotating the positioning holes 14 at different positions according to the sizes of the sheet metal parts to be bent, so that the bending requirements of the sheet metal parts with different sizes are met.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can substitute or change the technical solution and its concept of the present application within the technical scope disclosed in the present application, and shall be covered by the scope of the present application.
