Description

Technical Field

[0001] This utility model belongs to the field of longitudinal beam reinforcing plate processing technology, and more specifically, it relates to an adjustable positioning mechanism for longitudinal beam reinforcing plate stamping die. Background Technology

[0002] Longitudinal beam reinforcement plates are components used to enhance the structural strength of automotive longitudinal beams. They are typically installed on the inner and outer plates of the longitudinal beams to improve vehicle safety and overall structural strength in collisions. Currently, due to the complex structure of longitudinal beam reinforcement plates, they are produced in a single stamping process using molds. The stamping molds for longitudinal beam reinforcement plates are usually bolted to the worktable of the stamping machine using mounting screw holes. However, in actual stamping processes, the size of longitudinal beam reinforcement plates varies for different vehicle models, thus requiring different sizes and structures for the stamping molds. This demonstrates that the fixed mounting hole structure of traditional stamping machine worktables cannot be adjusted for centering and installation according to the different sizes of longitudinal beam reinforcement plate stamping molds. Different sized longitudinal beam reinforcement plate stamping molds require custom-made worktable mounting holes for different stamping machine sizes, reducing the applicability of the stamping machine worktable for positioning and installing longitudinal beam reinforcement plates, and increasing equipment procurement, commissioning, and installation costs.

[0032] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0033] like Figures 1-6 As shown, this utility model provides an adjustable positioning mechanism for a stamping die for a longitudinal beam reinforcing plate, including a lower die 4; positioning guide posts 13 are welded to the four corners of the upper side of the lower die 4; it also includes a clamping device 5, a transverse threaded adjusting rod 10, and a bidirectional threaded clamping rod 11; a base 1 is rotatably connected to the outer side of the transverse threaded adjusting rod 10, and a transverse horizontal sliding plate 2 is slidably connected to the upper side of the base 1; a transverse positioning adjusting knob 12 is installed at the left end of the transverse threaded adjusting rod 10; the front and rear ends of the transverse horizontal sliding plate 2 are provided with through holes, and a longitudinal threaded adjusting rod 8 is rotatably connected in the through holes of the transverse horizontal sliding plate 2; a longitudinal positioning adjusting knob 6 is installed at the front end of the longitudinal threaded adjusting rod 8; the outer side of the bidirectional threaded clamping rod 11 is close to A longitudinal horizontal slide 3 is rotatably connected to the left and right ends. A lower mold 4 is placed on the upper side of the longitudinal horizontal slide 3. A transverse clamping knob 7 is installed on the right end of the bidirectional threaded clamping rod 11. The clamping device 5 includes a slide frame 501, a longitudinal clamping knob 502, a guide rod 503, a horizontal clamping plate 504, a bidirectional threaded limiting rod 505, and a clamping block 506. The horizontal clamping plate 504 is slidably connected to the outer side of the guide rod 503. The slide frame 501 is welded to both the left and right ends of the guide rod 503. A clamping block 506 is welded to the center of the upper side of the slide frame 501. The slide frame 501 is rotatably connected to the outer side of the bidirectional threaded limiting rod 505. A longitudinal clamping knob 502 is installed at the front end of the bidirectional threaded limiting rod 505.

[0034] In this embodiment, there are two sets of horizontal clamping plates 504, which are symmetrically distributed front and back. Each horizontal clamping plate 504 has a threaded through hole and a through hole that pass through from front to back. The guide rod 503 is inserted into the through hole of the horizontal clamping plate 504. The positive threaded end of the outer side of the bidirectional threaded limiting rod 505 is engaged with the threaded through hole of the front horizontal clamping plate 504, and the reverse threaded end of the outer side of the bidirectional threaded limiting rod 505 is engaged with the threaded through hole of the rear horizontal clamping plate 504. During the process of the longitudinal clamping knob 502 driving the bidirectional threaded limiting rod 505 to rotate, the bidirectional threaded limiting rod 505 drives the two sets of horizontal clamping plates 504 to move back and forth in opposite directions, so that the two sets of horizontal clamping plates 504 press against the front and rear sides of the lower mold 4. The horizontal clamping plates 504 are centered and fixed to the lower mold 4 according to the longitudinal width of the lower mold 4, so as to prevent the lower mold 4 from moving back and forth horizontally.

During the rotation of the bidirectional threaded clamping rod 11, it drives the clamping blocks 506 welded to the upper side of the two sets of skateboard frames 501 to move from left to right in opposite directions. The two sets of clamping blocks 506 clamp the left and right sides of the lower mold 4 according to the lateral width of the lower mold 4, so as to prevent the lower mold 4 from moving horizontally from left to right.

[0036] In this embodiment, the lower side of the longitudinal horizontal slide 3 is provided with two sets of cuboid protrusions. A slider 9 is welded to the center of the lower side of the longitudinal horizontal slide 3. A threaded through hole is provided at the center of the slider 9. The outer side of the longitudinal threaded adjusting rod 8 is threadedly engaged in the threaded through hole of the slider 9. During the rotation of the longitudinal threaded adjusting rod 8, the longitudinal horizontal slide 3 connected to the slider 9 moves back and forth, thereby adjusting the front and back position of the lower mold 4 on the upper side of the longitudinal horizontal slide 3. A through groove is provided at the center of the upper side of the longitudinal horizontal slide 3. The square protrusion of the slide plate frame 501 is embedded in the through groove of the longitudinal horizontal slide 3. The front and rear sides of the square protrusion of the slide plate frame 501 are respectively attached to the front and rear groove walls of the through groove of the longitudinal horizontal slide 3. The longitudinal horizontal slide 3 supports the slide plate frame 501 to move horizontally left and right along the through groove, ensuring that the clamping block 506 welded to the slide plate frame 501 contacts the left and right sides of the lower mold 4 in parallel.

[0037] In this embodiment, the upper side of the transverse horizontal slide plate 2 is provided with three sets of grooves. The cuboid protrusions of the longitudinal horizontal slide 3 and the slider 9 are respectively embedded in the three sets of grooves of the transverse horizontal slide plate 2. A protrusion is provided at the center of the lower side of the transverse horizontal slide plate 2. The protrusion is provided with a threaded through hole that runs from left to right. The outer side of the transverse threaded adjustment rod 10 is threadedly engaged with the threaded through hole of the protrusion of the transverse horizontal slide plate 2. The transverse threaded adjustment rod 10 drives the transverse horizontal slide plate 2 to move left and right. The transverse horizontal slide plate 2 drives the upper side of the longitudinal horizontal slide 3 to place the lower mold 4 for left and right position adjustment. The lower side of the transverse horizontal slide plate 2 is provided with two sets of protrusions.

[0038] In this embodiment, the upper side of the base 1 is provided with three sets of grooves. The protrusions and protrusions of the horizontal sliding plate 2 are respectively embedded in the three sets of grooves on the upper side of the base 1. The front and rear sides of the protrusions of the horizontal sliding plate 2 are respectively attached to the front and rear groove walls of the grooves of the base 1, ensuring that the base 1 supports the horizontal sliding plate 2 to move horizontally in the left and right directions.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In the process of centering and clamping the lower mold 4 during installation, the lower mold 4 is first placed on the upper side of the longitudinal horizontal slide 3. Then, the transverse clamping knob 7 is rotated, which drives the bidirectional threaded clamping rod 11 to rotate. Since the forward and reverse threaded ends of the outer side of the bidirectional threaded clamping rod 11 are respectively engaged and connected in the square convex threaded through holes of the two sets of slide frames 501, the rotation of the bidirectional threaded clamping rod 11 drives the clamping blocks 506 welded to the upper side of the two sets of slide frames 501 to move left and right in opposite directions until the two sets of clamping blocks 506 separate. Do not place the clamping blocks 506 on the left and right sides of the lower mold 4. Position and clamp the lower mold 4, which has different transverse widths, in a centered manner. Then, manually rotate the two sets of longitudinal clamping knobs 502. The longitudinal clamping knobs 502 drive the bidirectional threaded limit rod 505 to rotate. Since the forward and reverse threaded ends of the outer side of the bidirectional threaded clamping rod 11 are respectively engaged and connected in the threaded through holes of the two sets of horizontal clamping plates 504, the rotation of the bidirectional threaded clamping rod 11 drives the two sets of horizontal clamping plates 504 to move back and forth along the guide rod 503 until the two sets of horizontal clamping plates... Clamping plates 504 are respectively attached to the front and rear sides of the lower mold 4, completing the front-to-back centering and clamping of the lower mold 4 with different longitudinal widths by two sets of horizontal clamping plates 504. If it is necessary to adjust the front-to-back position of the lower mold 4, the longitudinal positioning adjustment knob 6 is manually rotated. The longitudinal positioning adjustment knob 6 drives the longitudinal threaded adjustment rod 8 to rotate, and the longitudinal threaded adjustment rod 8 drives the slider 9, which is engaged with the outer side, to move back and forth along the groove of the transverse horizontal slide plate 2. The slider 9 drives the longitudinal horizontal slide 3 welded to the upper side to move forward or backward. The smooth table 3 drives the lower mold 4, which is clamped on the upper side, to move forward or backward synchronously. If it is necessary to adjust the left and right position of the lower mold 4, the horizontal positioning adjustment knob 12 is manually turned. The horizontal positioning adjustment knob 12 drives the horizontal thread adjustment rod 10 to rotate. The horizontal thread adjustment rod 10 drives the horizontal horizontal slide plate 2, which is engaged with the outer side, to move left and right along the groove of the base 1. The horizontal horizontal slide plate 2 drives the vertical horizontal slide table 3 to move left or right. The vertical horizontal slide table 3 drives the lower mold 4, which is clamped on the upper side, to move left or right synchronously.

[0041] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The lower mold 4 used above are all common components on the market; upon purchase and use, simply connect them according to the instruction manual purchased with the product, and therefore will not be elaborated upon further here.
