Description
Technical Field
[0001] The utility model belongs to the technical field of forging, and particularly relates to a forging intermediate of a battery pack bracket. Background Art
[0002] A battery pack bracket is a fixing bracket for a battery pack in an electric vehicle or a hybrid vehicle. With the popularization of electric transportation means, the safe and stable fixation of the battery pack becomes particularly important. The bracket can ensure the stability and safety of the battery pack during vehicle driving by providing strong support and fixation functions.
[0003] Before machining the battery pack bracket, forging technology is usually selected to manufacture the blank of the aluminum alloy battery pack bracket. The forging process of the blank mainly includes blanking → chamfering → heating → forging → trimming → solution aging → alkali washing, flaw detection, etc. → inspection and packaging. After packaging, the blank is sent to a machining factory. The most important process in the production process of the blank is forging. Forging refers to a forging intermediate of the blank obtained by forging deformation of a metal blank. Subsequent processes such as trimming, solution aging, alkali washing, and machining are all based on the forging intermediate. Therefore, how to ensure the quality of the intermediate and facilitate the automated operation of the entire forging process and machining has become a key challenge faced by forging manufacturers. Summary of the Utility Model
[0004] In view of this, in order to solve the problems existing in the prior art, the purpose of the utility model is to provide a forging intermediate of a battery pack bracket, which has the effects of being convenient for clamping, facilitating automation, being able to make way, and preventing the generation of folding defects on the upper end surface of the body.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A forging intermediate of a battery pack bracket, which includes: a body and a clamping column;
[0007] The clamping column is arranged on the body, and there is an included angle α between the axis of the clamping column and the upper end surface of the body;
[0008] The clamping column includes a first part and a second part connected to each other. The outer contour of the first part is smaller than that of the second part, and the second part is connected to the upper end surface of the body.
[0009] The specific technical effects are as follows: By providing clamping columns on the body, it is convenient to use clamping jaws during the forging process and subsequent trimming operations, which is conducive to automation, and the clamping columns can play a positioning role in subsequent processes; The clamping columns adopt a two-section design of a first part and a second part, which can improve the product reliability, and the outer contour of the first part is smaller than that of the second part. During the forging process, the excess material on the first part can be pressed onto the second part, so that the excess material generated due to forging will not appear on the upper end surface of the body, thus avoiding the generation of folding defects.
[0010] Further, the radial cross-section of the second part is circular, and the second part is connected to the first part through a connecting portion.
[0011] The specific technical effects are as follows: The second part is designed to be circular, so that the excess material generated by forging the first part can be completely avoided from being generated on the second part.
[0012] Further, the height of the first part is H, and the range of H is 13 mm to 15 mm.
[0013] The specific technical effects are as follows: The height of the first part is not likely to be too high, and it is more conducive to the demolding of the forging die and the trimming die when the height of the first part is within the range of 13 mm to 15 mm.
[0014] Further, the radial cross-section of the first part is circular.
[0015] The specific technical effects are as follows: The circular design is simple and has strong versatility.
[0016] Further, the radial cross-section of the first part is diamond-shaped.
[0017] The specific technical effects are as follows: The diamond shape is more conducive to clamping by the clamping jaws, and positioning can be carried out depending on any two straight sides of the diamond.
[0018] Further, the first part and the second part are coaxially arranged.
[0019] Further, the body includes a long side portion and a short side portion that are connected to each other, and a V-shaped structure is provided between the short side portion and the long side portion.
[0020] Further, a fillet is formed at the connection between the short side portion and the long side portion.
[0021] The specific technical effects are as follows: Setting a fillet with a relatively large radius at the connection between the short side portion and the long side portion makes the material flow more smoothly during the forging process, and avoids forging defects such as large folding and lack of material at this location.
[0022] Further, the range of the included angle α is 30° to 90°.
[0023] The specific technical effect is that when the included angle α is designed within the above-mentioned dimension range, it can not only avoid the interference between the chuck and the main body when the chuck clamps the clamping column due to too small an angle, but also avoid the situation of mold cracking caused by the thinning of the mold wall thickness due to too small an angle.
[0024] The beneficial effects of the present utility model are as follows:
[0025] (1) By providing a clamping column on the main body, it is convenient to use the chuck for clamping during the forging process and subsequent trimming processes, which is beneficial for automation, and the clamping column can play a positioning role in subsequent processes;
[0026] (2) The clamping column adopts a two-section design of a first part and a second part, which can improve the product reliability. Moreover, the outer contour of the first part is smaller than that of the second part. During the forging process, the excess material on the first part can be pressed onto the second part, so that the excess material generated by forging will not appear on the upper end face of the main body, thereby avoiding the generation of folding defects and improving the stability of the entire forging intermediate piece.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
[0035] As Figure 1 shown, a forging intermediate piece of a battery pack bracket includes a body 1 and a clamping column 2;
[0036] The clamping column 2 is arranged on the body 1, and there is an included angle α between the axis of the clamping column 2 and the upper end surface of the body 1;
[0037] The clamping column 2 includes a first part 3 and a second part 4 connected to each other. The outer contour of the first part 3 is smaller than that of the second part 4, and the second part 4 is connected to the upper end surface of the body 1.
[0038] It should be noted here that: by arranging the clamping column 2 on the body 1, it is convenient to use clamping jaws for clamping during the forging process and subsequent trimming processes, which is beneficial for automation, and the clamping column 2 can play a positioning role in subsequent processes; the clamping column 2 adopts a two-section design of the first part 3 and the second part 4, which can improve the product reliability, and the outer contour of the first part 3 is smaller than that of the second part 4. During the forging process, the excess material on the first part 3 can be pressed onto the second part 4, so that the excess material generated due to forging will not be generated on the upper end surface of the body 1, thereby avoiding the generation of folding defects.
[0039] The radial cross-section of the second part 4 is circular, and the second part 4 is connected to the first part 3 through a connecting part 5.
[0040] It should be noted here that: the second part 4 is designed to be circular, so that the excess material generated by forging the first part 3 can be completely avoided on the second part 4.
[0041] The height of the first part 3 is H, and the range of H is 13 mm to 15 mm.
[0042] It should be noted here that: the height of the first part 3 should not be too high, and the height of H in the range of 13 mm to 15 mm is more conducive to the demolding of forging dies and trimming dies.
[0043] The radial cross-section of the first part 3 can also be in the shape of a parallelogram, polygon, etc.
[0044] The radial cross-section of the first part 3 is circular.
[0045] It should be noted here that: compared with parallelograms and polygons, the circular design is simpler and more versatile.
[0046] See Figures 1 to 3 As shown, the radial cross-section of the first part 3 is diamond-shaped.
[0047] It should be noted here that: most of the shapes of the clamping claws are V-shaped structures. The diamond shape is more conducive to the clamping of the clamping claws. And if there are positioning requirements in subsequent processes such as trimming and machining, positioning can be relied on any two straight sides of the diamond.
[0048] The first part 3 and the second part 4 are coaxially arranged.
[0049] It should be noted here that: the axis directions of the first part 3 and the second part 4 are parallel to the forging direction of the forging die.
[0050] The body 1 includes a long side part 6 and a short side part 7 that are connected to each other. A V-shaped structure is arranged between the short side part 7 and the long side part 6.
[0051] A fillet 8 is formed at the connection between the short side part 7 and the long side part 6.
[0052] It should be noted here that: setting a fillet 8 with a larger radius at the connection between the short side part 7 and the long side part 6 makes the material flow more smoothly during the forging process, and avoids forging defects such as large folds and lack of materials at this place.
[0053] The range of the included angle α is 30° to 90°.
[0054] It should be noted here that: the included angle α is designed within this dimension range, which can not only avoid interference between the clamping claws and the body 1 when clamping the clamping column due to too small an angle, but also avoid the situation of die cracking caused by the thinning of the die wall due to too small an angle.
[0055] The beneficial effects of the present utility model are:
[0056] (1), By arranging the clamping column 2 on the body 1, it is convenient to use the clamping claws for clamping during the forging process and subsequent trimming and other processes, which is conducive to automation, and the clamping column 2 can play a positioning role in subsequent processes;
[0057] (2), The clamping column 2 adopts a two-section design of the first part 3 and the second part 4, which can improve the product reliability. And the outer contour of the first part 3 is smaller than the outer contour of the second part 4. During the forging process, the excess material on the first part 3 can be pressed on the second part 4, so that the excess material generated due to forging will not be generated on the upper end surface of the body 1, thus avoiding the generation of folding defects and improving the stability of the entire forging intermediate piece.
