The two sides of the groove side walls 12 are respectively connected to the groove bottom wall 11 and the groove outer wall 13 in a circular arc transition. A plurality of weight-reducing through holes 21 are provided on the groove bottom wall 11 to reduce the weight of the module seat 1 and thus reduce the weight of the automobile battery box. When the module seat 1 is produced, a metal plate 2 is usually used, and the plurality of weight-reducing through holes 21 are centered between the two side walls of the metal plate 2. Since there are three groove side walls 12 and three groove outer walls 13 in the module seat 1, it is usually necessary to bend the metal plate 2 in four places in sequence in the prior art, that is, use a bending machine to bend the bending part 2 four times in sequence, resulting in reduced bending efficiency, and each bending position deviates from the predetermined target, which reduces the bending accuracy and thus reduces the product qualification rate.

[0004] Therefore, it is necessary to improve the bending device of the automobile battery box module seat in the prior art. Utility Model Content

[0030] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] like Figure 3-Figure 9 As shown, the bending device of the automobile battery box module seat of the utility model includes:

[0032] The bending groove 3 has an opening facing upwards, and the bottom of the bending groove 3 is an inner support wall 31. Both sides of the inner support wall 31 are connected to horizontal outer support walls 33 through vertical inner side walls 32;

[0033] The bending bead 4 extends in a longitudinal direction parallel to the bending groove 3 and is located directly above the inner support wall 31. The bottom of the bending bead 4 includes an inner pressure wall 41 facing the inner support wall 31, an outer pressure wall 43 facing the outer support wall 33, and an outer side wall 42 corresponding to the inner side wall 32.

[0034] The lifting component 5 drives the bending strip 4 to move in the vertical direction between the bending station and the access station. At the bending station, the gaps between the inner support wall 31 and the inner pressure wall 41, the inner side wall 32 and the outer side wall 42, and the outer support wall 33 and the outer pressure wall 43 are all consistent with the thickness of the metal plate 2; at the access station, an access gap is provided between the bending strip 4 and the bending groove 3 for the metal plate 2 to be placed flat on the bending groove 3 and for the module base 1 to be taken out from the bending groove 3.

[0035] When the bending device is in use, the bending strip 4 is first moved upward to the storage and retrieval station through the lifting assembly 5, so that there is a certain distance between the bending strip 4 and the bending groove 3, which is convenient for placing the straight long metal plate 2 flat on the bending groove 3, and using the two outer support walls 33 at the top of the bending groove 3 to horizontally support the metal plate 2, and adjust the position of the metal plate 2 so that it is centered directly above the bending groove 3, while the length direction of the metal plate 2 is consistent with the length direction of the bending groove 3.

[0036] Then, the lifting assembly 5 controls the bending strip 4 to continuously descend to the bending station, so that the straight metal plate 2 is bent to form the module seat 1. Specifically, at the bending station, the inner pressure wall 41 of the bending strip 4 and the inner support wall 31 of the bending groove 3 respectively abut the top surface and bottom surface of the bottom wall 11 of the module seat 1 groove, and the outer wall 42 of the bending strip 4 and the inner wall 32 of the bending groove 3 respectively abut the outer surface and inner surface of the side wall 12 of the module seat 1 groove, and at the same time, the outer pressure wall 43 of the bending strip 4 and the outer support wall 33 of the bending groove 3 respectively abut the top surface and bottom surface of the outer wall 13 of the module seat 1 groove.

[0037] After the metal plate 2 is bent to form the module base 1 , the lifting assembly 5 controls the bending strip 4 to rise to the access station, so as to facilitate the removal of the module base 1 formed by bending the metal plate 2 .

[0038] Therefore, the bending device of the present invention only needs to control the bending strip 4 to perform a lifting and reciprocating motion through the lifting component 5 to bend the straight metal plate 2 placed flat on the bending groove 3 into a shape as shown in FIG. Figure 1 The module base 1 shown is bent at four sides, thereby greatly improving the processing efficiency.

[0039] A further improvement is that both sides of the inner side wall 32 are connected to the inner support wall 31 and the outer support wall 33 in a circular arc transition, and both sides of the outer side wall 42 are connected to the inner pressure wall 41 and the outer pressure wall 43 in a circular arc transition.

[0040] After adopting the above structure, in the module base 1 formed by bending the metal plate 2, the two sides of the groove side wall 12 are connected to the groove bottom wall 11 and the groove outer wall 13 in an arc transition. On the one hand, the aesthetics of the groove side wall 12 is improved, and on the other hand, the structural stability of the module base 1 is ensured.

[0041] A further improvement is that it further includes a positioning component 6, which is used to position the metal plate 2 mounted on the outer supporting wall 33.

[0042] The positioning assembly 6 facilitates positioning of the metal plate 2 mounted on the outer support wall 33 , thereby ensuring the molding accuracy of the module base 1 , reducing differences between batches of products, and improving product quality.

[0043] As a further improvement, the positioning assembly 6 is also used to prevent the metal plate 2 from being offset in the horizontal direction when the bending strip 4 is lowered from the access station to the bending station.

[0044] With the above design, the positioning assembly 6 can also prevent the metal plate 2 from shifting horizontally when the bending strip 4 is in contact with the metal plate 2 and continues to descend, thereby ensuring the quality of the metal plate 2 being bent into the module seat 1.

[0045] A further improvement is that the positioning assembly 6 includes a positioning boss 61, which extends in the vertical direction and has a cross-section that matches the weight-reducing through-hole 21 on the metal plate 2. The positioning boss 61 passes through the inner support wall 31 and is slidably arranged in the vertical direction; a chamfer 611 is provided at the top of the positioning boss 61; and an elastic member 62 is connected to the bottom of the positioning boss 61, which supports the positioning boss 61.

[0046] like Figure 1 The module base 1 shown and Figure 2The metal plates 2 are each provided with five weight-reducing through holes 21 spaced apart along their length directions (in actual production, the number and distribution of the weight-reducing through holes 21 on the metal plate 2 and the module seat 1 can be flexibly adjusted). Therefore, correspondingly, in the utility model, the positioning assembly 6 is provided with five positioning bosses 61 spaced apart, and the five positioning bosses 61 correspond one-to-one to the five weight-reducing through holes 21; not only that, the inner support wall 31 of the bending groove 3 is also provided with five directional through holes 35 extending in the vertical direction and spaced apart along the length direction of the bending groove 3, and the five directional through holes 35 correspond one-to-one to the five positioning bosses 61, and the circumferential inner wall of the directional through hole 35 is sealed and fitted with the circumferential outer edge of the positioning boss 61 to ensure that the positioning boss 61 can move smoothly in the vertical direction.

[0047] In addition, the positioning boss 61 is also connected to an elastic member 62, which is a compression spring arranged at the bottom of the positioning boss 61. The positioning boss 61 is supported by the elastic member 62 so that in the absence of external force, the top of the positioning boss 61 can protrude from the inner support wall 31 and be higher than the outer support wall 33. When the metal plate 2 is placed on the bending groove 3, the five weight-reducing through holes 21 are aligned with the five positioning bosses 61 for placement, and the chamfer 611 at the top of the positioning boss 61 makes it convenient to seal the weight-reducing through hole 21 on the outside of the positioning boss 61. Figure 3 and Figure 4 shown.

[0048] After the metal plate 2 is placed, the lifting assembly 5 controls the bending strip 4 to move downward. During the descent of the bending strip 4, it first contacts the top of the positioning boss 61. The bending strip 4 continues to descend, compressing the elastic member 62 while contacting the metal plate 2 and cooperating with the bending groove 3 to bend the metal plate 2. Since the circumferential outer edge of the positioning boss 61 is sealed with the weight-reducing through-hole 21 of the metal plate 2, the horizontal position of the metal plate 2 can be prevented from shifting during the descent of the bending strip 4, so that the entire device can bend the predetermined part of the metal plate 2, thereby ensuring the product quality of the metal plate 2 bent into the module seat 1, and avoiding the module seat 1 product being unqualified due to the displacement of the metal plate 2 after being compressed.

[0049] In order to further ensure that the circumferential inner wall of the weight-reducing through hole 21 can be sealed and fitted with the circumferential outer edge of the positioning boss 61 , the depth of the chamfer 611 is smaller than the thickness of the metal plate 2 , that is, smaller than the hole depth of the weight-reducing through hole 21 .

[0050] A further improvement is that the top and bottom ends of the elastic member 62 are respectively provided with a transverse plate 63 and a base 7, and the outer cover of the elastic member 62 is provided with an axially retractable protective sleeve 64, and the two ends of the protective sleeve 64 are respectively fixedly connected to the base 7 and the transverse plate 63.

[0051] Specifically, the five positioning bosses 61 are all fixed to the top surface of the horizontal cross plate 63, the base 7 is fixedly set, the two ends of the compression spring and the two ends of the protective cover 64 are connected to the cross plate 63 and the base 7 respectively, and the protective cover 64 is used to isolate and protect the compression spring to prevent external damage; the lower ends of the bending groove 3 are fixedly connected to the base 7 through the support block 34, and the length direction of the base 7 is consistent with the length direction of the bending groove 3 and the bending strip 4.

[0052] A further improvement is that the protective sleeve 64 includes an outer tube 641 and an inner tube 642, the circumferential inner wall of the outer tube 641 is sealedly connected to the circumferential outer edge of the inner tube 642, one of the outer tube 641 and the inner tube 642 is fixedly connected to the base 7, and the other is fixedly connected to the cross plate 63.

[0053] In the present invention, the top end of the inner cylinder 642 is fixed below the transverse plate 63, the bottom end of the outer cylinder 641 is fixed above the base 7, the circumferential outer edge of the bottom of the inner cylinder 642 is sealed with the circumferential inner wall of the top of the outer cylinder 641, and the elastic member 62 is arranged in a protective cavity formed by the inner cylinder 642, the outer cylinder 641, the transverse plate 63 and the base 7. In this way, the axial length of the protective sleeve 64 can be adjusted and the elastic member 62 can be protected.

[0054] A further improvement is that the length of the bending groove 3 and the length of the bending strip 4 are both greater than the length of the metal plate 2. This design ensures that during the bending process, the bending groove 3 and the bending strip 4 can fully contact both sides of the metal plate 2, thereby ensuring the product quality of the module base 1 formed after the metal plate 2 is bent.

[0055] The lifting assembly 5 includes two support frames 51, both of which are inverted U-shaped structures and are respectively fixed above the two ends of the base 7. The top fixed frames of the two support frames 51 are provided with a crossbeam 52, which is arranged horizontally and the length direction is parallel to the bending groove 3. The crossbeam 52 is provided with oil cylinders 53 distributed at equal intervals along its length direction. The cylinder barrel of the oil cylinder 53 is arranged vertically downward and fixed on the crossbeam 52. The bottom end of the piston rod is fixedly connected to the bending strip 4. The top of the bending strip 4 is also provided with guide rods 54 distributed at equal intervals along its length direction and extending in the vertical direction. The crossbeam 52 is provided with a guide sleeve 55 that corresponds to the guide rod 54 one by one and slides together.

[0056] After adopting the above structure, the crossbeam 52 is fixedly installed using the support frame 51. After the oil cylinder 53 is started, the piston rod acts on the bending strip 4. Under the action of the sliding guide rod 54 and the guide sleeve 55, the bending strip 4 is stably moved in the vertical direction between the bending station and the storage and retrieval station.

[0057] 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 technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
