During the production and processing of an installation bracket of an automobile fuel tank, multiple stamping steps are required. In this process, in order to save time and effort, progressive dies are generally used for processing.

[0003] When the currently used progressive die is damaged after long-term use and the bottom plate is intact, the bottom plate and the die holder cannot be disassembled, and thus the upper and lower die holders cannot be replaced separately. Instead, the bottom plate and the die holder need to be replaced as a whole, which easily causes a large amount of waste of resources. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following disadvantages in the prior art: when the currently used progressive die is damaged after long-term use and the bottom plate is intact, the bottom plate and the die holder cannot be disassembled, and thus the upper and lower die holders cannot be replaced separately. Instead, the bottom plate and the die holder need to be replaced as a whole, which easily causes a large amount of waste of resources. The utility model provides a progressive die for processing an installation bracket of an automobile fuel tank.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Terms such as "upper", "lower", "left", "right", "middle", and "one" cited in the present utility model are only for the convenience of clear narration and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0022] Referring to Figures 1-4 , a progressive die for processing an automotive fuel tank mounting bracket includes two bottom plates 1, an upper die base 4, and a lower die base 3. A plurality of stamping heads are arranged on the upper die base 4, and a plurality of cutting edges are arranged on the lower die base 3. A plurality of support blocks 2 are fixedly connected to each bottom plate 1. The plurality of support blocks 2 are connected by a cross bar 11. A plurality of grooves are formed on one side surface of the upper die base 4 and the lower die base 3. A round hole 14 is formed on one inner wall of each groove. A limiting component is arranged on each support block 2. The limiting component includes an insertion shaft 16 slidably mounted on the support block 2. The insertion shaft 16 is slidably connected to the round hole 14. An installation cavity 17 is formed on the support block 2. The insertion shaft 16 is connected to the inner wall of the installation cavity 17 through a first spring 15. A plurality of pressing plates 6 are fixedly connected to the cross bar 11.

[0023] A sliding rod 13 is connected to each bottom plate 1 through a second spring. The cross section of the sliding rod 13 is L-shaped. A convex block 19 is fixedly connected to one side surface of the sliding rod 13. The convex block 19 is clamped with the cross bar 11. When the sliding rod 13 is pulled, during the relative sliding process of the sliding rod 13 and the bottom plate 1, the second spring deforms. When the convex block 19 disengages from the cross bar 11 and no longer clamps with the cross bar 11, the sliding rod 13 and the convex block 19 cannot limit the movement of the cross bar 11.

[0024] The cross section of each cross bar 11 is L-shaped. A rack plate 8 is fixedly connected to each cross bar 11. Earmuffs are fixedly connected to one side of two of the support blocks 2. A rotating shaft 12 is rotatably connected to each earmuff. A gear 18 is fixedly connected to the rotating shaft 12. The cross section of the rotating shaft 12 is I-shaped. The gear 18 is meshed with the rack plate 8. When the rotating shaft 12 is rotated, during the relative rotation process of the rotating shaft 12 and the earmuff, the gear 18 will be meshed with the rack plate 8. Under the driving action of the rack plate 8, the cross bar 11 can be driven to move, facilitating the control of the movement of the cross bar 11.

[0025] A plurality of fixing frames 7 with an I-shaped cross-section are fixedly connected to the plurality of supporting blocks 2. A reinforcing rod 10 is rotatably connected to each fixing frame 7. Each reinforcing rod 10 is connected to the corresponding cross bar 11 through a bolt. A plurality of threaded grooves are formed in each cross bar 11. One end of the bolt passes through the reinforcing rod 10 and is threadedly connected to the threaded hole, so that the reinforcing rod 10 and the cross bar 11 can be firmly connected together. The reinforcing rod 10, the cross bar 11 and the supporting block 2 form a triangular support, and the supporting effect on the die base is better.

[0026] A plurality of limiting rods 9 are fixedly connected to the upper die base 4, and a plurality of guide sleeves 5 are fixedly arranged on the lower die base 3. When the upper die base 4 and the lower die base 3 are pressed together, each limiting rod 9 is inserted into the corresponding guide sleeve 5, and each punch and knife edge correspond one by one, so that the workpiece can be continuously processed.

[0027] In the present utility model, during use, first rotate a plurality of bolts so that one end thereof is disengaged from the threaded holes on the cross bar 11. Then, pull the sliding rod 13. During the relative sliding of the sliding rod 13 and the bottom plate 1, since one end of the second spring is fixedly connected to the sliding rod 13 and the other end is fixedly connected to the bottom plate 1, the second spring is deformed, and the convex block 19 is disengaged from the cross bar 11 and no longer engages with the cross bar 11. Since one end of each first spring 15 is fixedly connected to the inner wall of the corresponding installation cavity 17 and the other end is fixedly connected to the insertion shaft 16, under the elastic force of the first spring 15, the plurality of insertion shafts 16 slide simultaneously in the corresponding installation cavities 17. During the process of the insertion shafts 16 contracting into the interior of the installation cavities 17, they will push the corresponding pressing plates 6 to move together, and the insertion shafts 16 are located outside the circular holes 14. Then, each supporting block 2 can be taken out from the grooves on the upper die base 4 or the lower die base 3, and the bottom plate 1 and the upper die base 4 or the lower die base 3 are disassembled. When the bottom plate 1 is damaged or the upper die base 4 or the lower die base 3 is damaged, the bottom plate 1 or the die base can be replaced separately, and there is no need to replace the bottom plate 1 and the die base as a whole, which can effectively avoid waste of a large amount of resources.

[0028] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and the like shall be understood in a broad sense.

[0029] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
