Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a steering column bracket forming mold structure. Background Art

[0002] The steering column is a component of the steering system that connects the steering wheel and the steering gear. A steering column bracket is required when installing the steering column. Before the steering column bracket is stamped and formed, it is necessary to spot weld the nut in the hole of the steering column bracket. Because the holes of the formed steering column bracket cannot be concentric when spot welding the nut and there is also the problem of the nut falling off, in order to solve the problem of welding the bracket and the nut, changes need to be made to the molding mold.

[0003] When the existing steering column bracket forming mold is used, the nut to be welded is usually directly inserted into the hole of the steering column bracket and then electric welding is performed. However, since there is a gap between the nut and the hole, the nut may move eccentrically during welding, resulting in eccentricity between the nut thread hole after spot welding and the hole of the steering column bracket, making it difficult to install and lock the steering column bracket in the later stage. Utility Model Content

[0004] The disclosed embodiment relates to a steering column bracket forming die structure, which is inserted into the center point of the hole of the workpiece through a concentric slide rod, and then the nut to be welded is mounted on the concentric slide rod, so that the nut slides into the hole of the workpiece through the concentric slide rod, so that the thread hole of the nut can be kept concentric with the hole of the workpiece under the action of the concentric slide rod.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please refer to Figures 1 to 6 :

[0031] Embodiment 1:

[0032] The utility model proposes a steering column bracket forming die structure, comprising: a base 1, a lower die 2 is fixedly installed on the top of the base 1; forming blocks 3 are fixedly installed on the left and right sides of the top of the lower die 2; a forming groove 4 is opened at the center of the top of the lower die 2; a shrinking groove 5 is opened at the center of the bottom of the forming groove 4; a push plate 6 is slidably installed inside the shrinking groove 5; a push plate 7 with a disc-shaped structure is fixedly installed on the top of the push plate 6; an inclined groove A8 with an inclined structure is opened on the push plate 6; a support column 9 is fixedly installed on the top of the lower die 2; a concentric sliding rod 10 is slidably installed inside the support column 9; a shrinking plate 11 is fixedly installed at the bottom end of the concentric sliding rod 10; the shrinking plate 11 is also slidably installed inside the lower die 2; and an inclined groove B12 with an inclined structure is opened on the shrinking plate 11.

[0033] The workpiece is placed on two forming blocks 3 so that both ends of the workpiece are located inside the limit seat 23, and then the nut to be welded is mounted on the concentric slide rod 10, so that the nut slides into the hole of the workpiece through the concentric slide rod 10 while maintaining concentricity, and then a spot welding machine is used to weld the nut so that the nut and the hole of the workpiece are installed concentrically.

[0034] Embodiment 2, on the basis of embodiment 1, a baffle plate 13 with a disc-shaped structure is fixedly installed on the circumferential outer wall of the concentric slide rod 10; one end of a spring A14 is embedded in the bottom of the baffle plate 13; the other end of the spring A14 is embedded in the inner bottom end of the support column 9; transmission grooves 15 are provided on the left and right sides of the interior of the lower mold 2; an L-shaped transmission frame 16 is slidably installed inside the transmission groove 15; a baffle plate 17 with a rectangular structure is fixedly installed on the inner side of the transmission frame 16; a spring B18 is embedded between the inner side of the baffle plate 17 and the inner wall of the transmission groove 15; a push column A19 is fixedly installed on the transmission frame 16; the push column A19 is slidably installed inside the inclined groove B12; a push column B20 is fixedly installed on the inner end of the transmission frame 16; the push column B20 is slidably installed inside the inclined groove A8; a driven plate 21 is fixedly installed on the top of the transmission frame 16.

[0035] After the nut and the workpiece are welded, the punching cylinder 29 is started to lower the punching cylinder 29 with the upper die 25 and the forming push block 28, so that the forming push block 28 is lowered to prepare for punching the workpiece on the limit seat 23 and the forming block 3. At the same time, the upper die 25 will also lower the pulling plate 26 and the pulling column 27, so that the pulling column 27 uses the inclined structure of the driven groove 22 to move the driven plate 21 and the transmission frame 16 inward. During the movement, the transmission frame 16 will synchronously move the push column A19 and the push column B20 inward, so that the push column A19 uses the inclined structure of the inclined groove B12 to move the driven plate 21 and the transmission frame 16 inward. The inclined structure brings the shrinkage plate 11 and the concentric slide rod 10 down, so that the concentric slide rod 10 is disengaged from the nut thread hole and the workpiece hole, preventing the concentric slide rod 10 from interfering with the subsequent stamping and forming of the workpiece, and the push column B20 will use the inclined structure of the inclined groove A8 to bring the push plate 6 and the push plate 7 down, so that the push plate 7 is retracted and hidden inside the shrinkage groove 5, so that the push plate 7 and the forming groove 4 together form a complete groove body, so that when the forming push block 28 pushes the workpiece, the workpiece can be stamped and formed under the action of the complete groove body and the forming push block 28.

[0036] Embodiment 3, on the basis of embodiment 2, a driven groove 22 is provided on the driven plate 21; the top of the driven groove 22 is an inclined structure; the limit seats 23 are also fixedly installed on the left and right sides of the top of the base 1; the limit seats 23 are located on the outside of the forming block 3; the top of the limit seat 23 is fixedly installed with a guide frame 24; the upper mold 25 is slidably installed on the guide frame 24; the pulling plates 26 are fixedly installed on the left and right sides of the top of the upper mold 25; the pulling column 27 is fixedly installed on the top of the pulling plate 26; the pulling column 27 is also slidably installed inside the driven groove 22; a forming push block 28 is fixedly installed at the center of the bottom of the upper mold 25; the forming push block 28 corresponds vertically to the position of the forming groove 4 up and down; a stamping cylinder 29 is fixedly installed at the center of the top of the guide frame 24; the output end of the stamping cylinder 29 is connected to the upper mold 25.

[0037] When the punching cylinder 29 rises with the forming push block 28, the push plate 7 and the concentric slide bar 10 rise with the cooperation of the corresponding structures, so that the push plate 7 pushes the workpiece inside the forming groove 4 during the rising process, making it easier for workers to pick up the workpiece.

[0038] Working principle:

[0039] First, place the workpiece on the two forming blocks 3 so that the two ends of the workpiece are located inside the limit seat 23, and then put the nut to be welded on the concentric slide bar 10, so that the nut can slide into the hole of the workpiece through the concentric slide bar 10 while maintaining concentricity, and then use a spot welding machine to weld the nut so that the nut and the hole of the workpiece are installed concentrically. Then, after the nut and the workpiece are welded, start the stamping cylinder 29 to lower the stamping cylinder 29 with the upper mold 25 and the forming push block 28, and lower the forming push block 28 to prepare for stamping the workpiece on the limit seat 23 and the forming block 3. At the same time, the upper mold 25 will also lower the pulling plate 26 and the pulling column 27, so that the pulling column 27 uses the inclined structure of the driven groove 22 to move the driven plate 21 and the transmission frame 16 inward. During the movement, the transmission frame 16 will synchronously move the push column A19 and the push column B20 inward. The push column A19 uses the inclined structure of the inclined groove B12 to bring the shrinking plate 11 and the concentric slide bar 10 down, so that the concentric slide bar 10 is separated from the nut thread hole and the workpiece hole, preventing the concentric slide bar 10 from interfering with the subsequent stamping and forming of the workpiece, and the push column B20 will use the inclined structure of the inclined groove A8 to bring the push plate 6 and the push plate 7 down, so that the push plate 7 is retracted and hidden inside the shrinking groove 5, so that the push plate 7 and the forming groove 4 together form a complete groove body, so that when the forming push block 28 pushes the workpiece, the workpiece can be stamped and formed under the action of the complete groove body and the forming push block 28, and then when the stamping cylinder 29 brings the forming push block 28 up, the push plate 7 and the concentric slide bar 10 rise with the cooperation of the corresponding structure, so that the push plate 7 during the rising process will push the workpiece inside the forming groove 4, making it easier for workers to pick up the workpiece.
