[0006] Furthermore, when the upper mold structure moves downward and cooperates with the lower mold structure to bend the sheet metal, the bending pressure block fits with the upper mold structure; when the upper mold structure moves upward and resets, the transverse bending spacing S is increased by the transverse driving part, so that the bending pressure block and the upper mold structure are transformed from a fitting state to a separated state.

[0007] Furthermore, a transverse guide rod is provided on the upper die structure, and the bending pressing block is slidably arranged on the transverse guide rod through a corresponding guide hole.

[0010] Furthermore, the positioning surface of the lower mold structure is provided with an enclosure for positioning the sheet metal part, and the enclosure has an opening on one side horizontally facing the bending block, and the bent portion of the sheet metal part positioned in the enclosure protrudes from the opening of the enclosure.

[0011] Furthermore, the height of the enclosure is smaller than the thickness of the sheet metal part, so that the sheet metal part in the enclosure is higher than the enclosure; a pressing plate is provided on the lower mold structure through a vertical driving part, and the sheet metal part in the enclosure is positioned by pressing the material through the pressing plate.

[0012] Furthermore, a transverse spring pressure sensor located in the installation cavity is elastically provided on the side of the upper mold structure that is in contact with the bending pressure block.

[0014] Beneficial effect: The utility model can adjust the size of the lateral bending distance between the bending pressure block and the lower mold structure, so that the bending pressure block and the upper mold structure are in contact during bending and separated during resetting, so that the bending pressure block does not contact the sheet metal part during resetting, avoiding scratches and damage to the sheet metal part caused by the upward resetting of the bending pressure block, and improving the quality and accuracy of the bending process. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Attached Figure 2 It is a structural schematic diagram of the bending upper die structure moving downward and cooperating with the lower die structure to bend the sheet metal part;

[0017] Attached Figure 3 It is a structural schematic diagram of the upper mold structure moving upward and resetting. DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] As attached Figure 1 As shown, a sheet metal bending mold for a wind power generation warehouse includes an upper mold structure 1 and a lower mold structure 4, the upper mold structure 1 has a bending block 2, and the table top of the lower mold structure 4 is a positioning surface for positioning the sheet metal 13; it includes a bending press 5, and the driving end of the bending press 5 is connected to the upper mold structure 1.

[0020] As attached Figure 2 and attached Figure 3As shown, the bending block 2 is arranged on the side of the upper mold structure 1, so that the bending block 2 and the lower mold structure 4 are staggered at a transverse bending spacing S; the upper mold structure 1 also has a transverse driving part 3 connected to the bending block 2, and the transverse driving part 3 drives the bending block 2 to move laterally and switch between fitting and separation relative to the upper mold structure 1 to adjust the size of the transverse bending spacing S. More specifically, when the upper mold structure 1 moves downward to cooperate with the lower mold structure 4 to bend the sheet metal 13, the bending block 2 fits with the upper mold structure 1; when the upper mold structure 1 moves upward and resets, the transverse bending spacing S is increased by the transverse driving part 3, so that the bending block 2 and the upper mold structure 1 are switched from the fitting state to the separation state, and the transverse driving part 3 is preferably a transverse cylinder. The utility model adjusts the size of the lateral bending spacing S between the bending pressure block 2 and the lower mold structure 1, so that the bending pressure block 2 and the upper mold structure 1 are attached during bending and separated during resetting, so that the bending pressure block 2 does not contact the sheet metal part 13 during resetting, avoiding scratches and damage to the sheet metal part 13 caused by the upward resetting of the bending pressure block 2, thereby improving the quality and accuracy of the bending process.

[0021] As attached Figure 1 As shown, a transverse spring pressure sensor 9 located in the mounting cavity is elastically provided on the side of the upper mold structure 1 that is bonded to the bending block 2. The bonding pressure is detected by the transverse spring pressure sensor 9. By comparing the built-in bonding calibration pressure value of the system with the real-time pressure value during the bending operation, it can be judged whether the bending block 2 is bonded to the upper mold structure 1. This is a fault detection method. When the real-time pressure value is less than the bonding calibration pressure value, it indicates that it is not bonded and needs to be repaired. When the real-time pressure value is the same as the bonding calibration pressure value, it indicates that it is bonded.

[0022] The upper mold structure 1 is provided with a transverse guide rod 6, and the bending block 2 is slidably arranged on the transverse guide rod 6 through corresponding guide holes. The transverse guide rod 6 supports the bending block 2, and the bending block 2 is guided by the transverse guide rod 6 when it moves laterally.

[0023] In order to prevent the bending pressing block 2 from falling off the rod due to a failure of the transverse driving part 3, an anti-falling block 7 is provided at the end of the transverse guide rod 6. At the same time, in order to buffer and protect the transverse movement of the bending pressing block 2, a retractable buffer 8 is elastically provided between the anti-falling block 7 and the bending pressing block 2, and the retractable buffer 8 is a spring elastically sleeved on the transverse guide rod 6.

[0024] As attached Figure 1 Shown and attached Figure 2As shown, the positioning surface of the lower mold structure 4 is provided with an enclosure 10 for positioning the sheet metal 13. The enclosure 10 has an opening on one side facing the bending block 2 horizontally, and the bent portion of the sheet metal 13 positioned in the enclosure 10 extends out from the opening of the enclosure 10. The height of the enclosure 10 is less than the thickness of the sheet metal 13, so that the sheet metal 13 in the enclosure 10 is higher than the enclosure 10; the lower mold structure 4 is provided with a press plate 11 through a vertical drive unit 12, and the sheet metal 13 in the enclosure 10 is pressed by the press plate 11 to achieve positioning, so as to ensure the stability of the sheet metal 13 during bending, and the vertical drive unit 12 is preferably a vertical cylinder.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
