Description

Technical Field

[0001] This utility model relates to the field of automotive stamping die technology, and in particular to a high-precision guide-type stamping die for new energy vehicle battery connectors. Background Technology

[0002] Stamping dies for battery connectors in new energy vehicles are key equipment for manufacturing high-quality, high-precision battery connectors.

[0003] Existing stamping dies, in order to facilitate disassembly and replacement on stamping equipment, have mostly abandoned the traditional threaded locking installation method and adopted the plug-in fixing installation method. However, the plug-in positioning components that fix the stamping die in multiple places lack a mechanism that can transmit synchronous driving force to drive them to simultaneously slide in and out to tighten and loosen the stamping die in one go. As a result, when replacing or disassembling the stamping die, it is necessary to drive multiple plug-in positioning components step by step to pull in and loosen the stamping die, which is more troublesome and inconvenient to operate, indirectly reducing the replacement efficiency of stamping dies.

[0013] Two vertical positioning shaft rings are symmetrically welded to the top of the upper mold on both sides of the connecting ring sleeve. Two horizontal support rods are symmetrically slidably installed between the two vertical positioning shaft rings and the connecting ring sleeve by spring push.

[0018] Furthermore,

[0019] The piston rod is telescopically mounted on an external hydraulic cylinder, which is used to drive the upper mold to move up and down and slide through the piston rod, so as to control the upper mold to stamp the battery connecting piece.

[0020] The high-precision guide-type stamping die for new energy vehicle battery connectors provided by this utility model has the following beneficial effects:

[0021] The two push rods, the transverse rotating shaft, and the springs on the four hexagonal longitudinal support rods together form a mechanism for synchronously inserting and loosening the four hexagonal longitudinal support rods.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] Please refer to Figures 1 to 5 ;

[0040] Example 1:

[0041] This utility model proposes a high-precision guide-type stamping die for new energy vehicle battery connecting pieces, including: a square support frame 1, and a lower die 2 is placed at the middle position of the top of the square support frame 1.

[0042] Two vertical positioning shaft plates 101 are welded at intervals to both ends of the two longitudinal support side plates of the square bearing frame 1. A hexagonal longitudinal support rod 102 is slidably inserted between each pair of adjacent vertical positioning shaft plates 101 via a spring pusher. The lower mold 2 has a rectangular structure and is inserted between four relatively opposite vertical positioning shaft plates 101 located on the inner side. The protruding ends of the four hexagonal longitudinal support rods 102 are inserted into and fitted with the two ends of the two long sides of the lower mold 2. The tail ends of 02 are all welded with force transmission rods 103 in the form of continuous vertical bends; the four force transmission rods 103 are symmetrically arranged, and the tail ends of each are welded with vertical force-bearing rods 1031; a transverse rotating shaft 5 is rotatably installed through the middle position of the longitudinal support direction of the square bearing frame 1, and two top rods 501 are symmetrically welded at both ends of the transverse rotating shaft 5. The two top rods 501 are arranged between the two vertical force-bearing rods 1031 on the corresponding side, and when rotating, the two ends respectively abut against the two vertical force-bearing rods 1031 on the corresponding side.

[0043] Four hexagonal longitudinal support rods 102 are used to insert and fix the lower mold 2 onto the square support frame 1; through the abutment power transmission between the two push rods 501 and the four vertical force-bearing rods 1031, the transverse rotating shaft 5 is twisted and driven, which can simultaneously push and drive the four force transmission rods 103 to slide away from each other, and drive and control the four hexagonal longitudinal support rods 102 to be simultaneously pulled away from the lower mold 2, so as to release the lower mold 2 in one go for disassembly and replacement. When the four hexagonal longitudinal support rods 102 are driven away from each other to pull away and loosen the lower mold 2, the four springs on them are compressed; when the new lower mold 2 is replaced and installed on the top of the square support frame 1. Afterwards, the transverse pivot 5 is released. Once the transverse pivot 5 is released, the four springs lose the pushing and compressing holding force from the four vertical force rods 1031. They will automatically rebound and push the four hexagonal longitudinal support rods 102 to slide closer to each other and reset and insert into the lower mold 2. The replaced lower mold 2 is then repositioned and inserted in one go. When the four hexagonal longitudinal support rods 102 are pushed back and reset, the two push rods 501 and the transverse pivot 5 can be driven to rotate and reset through the four force transmission rods 103 and the four vertical force rods 1031. The transverse pivot 5 can be torsionally driven through any one of the push rods 501.

[0044] Based on the above, the two push rods 501, the transverse rotating shaft 5, and the springs on the four hexagonal longitudinal support rods 102 together form a mechanism for driving the four hexagonal longitudinal support rods 102 to be inserted and tightened synchronously. Through this mechanism, the present invention can perform one-time efficient tightening and loosening of the lower mold 2. Compared with the prior art, the present invention can save the trouble of having to insert and loosen the four hexagonal longitudinal support rods 102 step by step to tighten and loosen the lower mold 2, which helps to indirectly improve the efficiency of disassembling and replacing the lower mold 2.

[0045] Preferred,

[0046] It also includes an upper mold 3 and a battery connecting piece 6, wherein the battery connecting piece 6 is stamped by the upper mold 3 and the lower mold 2.

[0047] Preferred,

[0048] Two vertical positioning shafts 201 are symmetrically welded at the middle positions of both ends of the lower mold 2, and the upper mold 3 is slidably installed on the two vertical positioning shafts 201;

[0049] The vertical positioning shaft 201 can slide and guide the upper die 3, ensuring the accuracy of the upper die 3's downward stamping.

[0050] Preferred,

[0051] A connecting ring 301 is welded to the middle of the top of the upper mold 3, and a drive ring 304 is rotatably mounted on the top part of the connecting ring 301.

[0052] Two vertical positioning shaft rings 302 are symmetrically welded to the top of the upper mold 3 on both sides of the connecting ring sleeve 301. Two horizontal support rods 303 are symmetrically slidably installed between the two vertical positioning shaft rings 302 and the connecting ring sleeve 301 through spring push. Two connecting rods 305 are symmetrically rotatably connected between the tail ends of the two horizontal support rods 303 and the outer circumference of the drive ring 304.

[0053] Preferred,

[0054] It also includes a piston rod 4, with a circular connecting plate 401 welded to the bottom end of the piston rod 4. The circular connecting plate 401 is inserted into the connecting ring sleeve 301, and the protruding parts at the ends of the two cross bracing rods 303 are inserted into the outer circumference of the circular connecting plate 401.

[0055] Two horizontal support rods 303 can be inserted and fixed to the circular connecting plate 401 and the connecting ring sleeve 301, positioning and connecting the piston rod 4 and the upper mold 3 together. The two horizontal support rods 303, the two connecting rods 305, and the drive ring 304 are connected to form two crank-slider mechanisms. Through these two mechanisms and the rebound pushing effect of the springs on the two horizontal support rods 303, the drive ring 304 can be twisted and released to drive the two horizontal support rods 303 to slide synchronously in opposite directions, thereby tightening and loosening the upper mold 3 in one go. In addition, the springs on the two horizontal support rods 303 and the two crank-slider mechanisms together form a mechanism to drive the two horizontal support rods 303 to slide synchronously in and out. Through this mechanism, the present invention can tighten and loosen the upper mold 3 in one go. Compared with the prior art, it can save the trouble of having to drive the two horizontal support rods 303 to tighten and loosen the upper mold 3 in steps, which helps to indirectly improve the efficiency of disassembling and replacing the upper mold 3.

[0056] Based on Example 1, Example 2:

[0057] Two vertical drive shafts 3041 are symmetrically welded on the outer circumference of the drive ring 304. The top parts of the two vertical drive shafts 3041 protrude above the drive ring 304, and the first ends of the two connecting rods 305 are rotatably connected to the bottom parts of the two vertical drive shafts 3041.

[0058] Torsional drive can be applied to the drive ring 304 by erecting the drive shaft 3041 at any point.

[0059] Preferred,

[0060] The piston rod 4 is telescopically mounted on an external hydraulic cylinder, which is used to drive the upper mold 3 to rise and slide through the piston rod 4, so as to control the upper mold 3 to stamp the battery connecting piece 6.

[0061] The working principle of this embodiment is as follows: the battery connecting piece 6 is stamped by the upper mold 3 and the lower mold 2. The piston rod 4 is telescopically mounted on the external hydraulic cylinder. The external hydraulic cylinder is used to drive the upper mold 3 to rise and slide through the piston rod 4, so as to control the upper mold 3 to stamp the battery connecting piece 6.

[0062] Four hexagonal longitudinal support rods 102 are used to insert and fix the lower mold 2 onto the square support frame 1; through the abutment power transmission between the two push rods 501 and the four vertical force-bearing rods 1031, the transverse rotating shaft 5 is twisted and driven, which can simultaneously push and drive the four force transmission rods 103 to slide away from each other, and drive and control the four hexagonal longitudinal support rods 102 to be simultaneously pulled away from the lower mold 2, so as to release the lower mold 2 in one go for disassembly and replacement. When the four hexagonal longitudinal support rods 102 are driven away from each other to pull away and loosen the lower mold 2, the four springs on them are compressed; when the new lower mold 2 is replaced and installed on the top of the square support frame 1. Afterwards, the transverse pivot 5 is released. Once the transverse pivot 5 is released, the four springs lose the pushing and compressing holding force from the four vertical force rods 1031. They will automatically rebound and push the four hexagonal longitudinal support rods 102 to slide closer to each other and reset and insert into the lower mold 2. The replaced lower mold 2 is then repositioned and inserted in one go. When the four hexagonal longitudinal support rods 102 are pushed back and reset, the two push rods 501 and the transverse pivot 5 can be driven to rotate and reset through the four force transmission rods 103 and the four vertical force rods 1031. The transverse pivot 5 can be torsionally driven through any one of the push rods 501.

[0063] Two cross bracing rods 303 can be inserted and fixed to the circular connecting plate 401 and the connecting ring sleeve 301, positioning and connecting the piston rod 4 and the upper mold 3 together; the two cross bracing rods 303, the two connecting rods 305 and the drive ring 304 are connected to form two crank-slider mechanisms. Through these two mechanisms and in conjunction with the rebound and pushing effect of the springs on the two cross bracing rods 303, twisting and releasing the drive ring 304 can drive the two cross bracing rods 303 to slide synchronously in opposite directions, releasing or positioning the upper mold 3 at one time, and disassembling and replacing the upper mold 3.

[0066] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.
