Description

Technical Field

[0001] The invention relates to the technical field of reinforcing plate stamping, in particular to a stamping and shaping fixture for a reinforcing plate of an automobile support. Background Art

[0002] Automobile bearing reinforcement plates are additional components designed to improve the strength and stability of automobile bearings. They are widely used to strengthen key parts such as engines, gearboxes, and suspension systems to ensure that these components can work stably and reliably during vehicle operation.

[0003] In the production process of automobile support reinforcement plates, stamping and shaping is one of the most critical processes. Stamping and shaping are used to perform plastic deformation on the reinforcement plates to obtain the required shape and size, ensuring a perfect fit between the reinforcement plates and the support.

[0004] When the existing technology performs stamping and shaping on the support reinforcement plate, the support reinforcement plate to be processed is usually placed on the worktable of the stamping equipment first, and then the support reinforcement plate is clamped and limited, and then the stamping head of the stamping equipment is started, and the stamping head stamps and forms the support reinforcement plate. However, although the existing stamping equipment can bend the support reinforcement plate, each support reinforcement plate is only subjected to stamping and bending processing once. Some of the support reinforcement plates after bending have insufficient bending amount or bending deformation deviation, and the bent support reinforcement plate cannot be shaped again, which reduces the bending effect of the support reinforcement plate. In addition, the steps of removing and installing the support reinforcement plate must be repeated after each support reinforcement plate is bent, thereby reducing the efficiency of stamping and bending multiple support reinforcement plates.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] See also Figure 1-Figure 5 A stamping and shaping fixture for a reinforcement plate of an automobile support includes a base plate 1 and a distance adjusting device 2. Two distance adjusting devices 2 are provided and are symmetrically connected to the front and rear side walls of the base plate 1. The distance adjusting device 2 includes a rectangular plate 21 installed on the side wall of the base plate 1. A sliding frame 22 is slidingly sleeved on the surface of the rectangular plate 21, and a positioning mechanism 23 is connected to the sliding frame 22.

[0038] See also Figure 1 and Figure 8 The positioning mechanism 23 includes two waist-shaped plates 232 symmetrically arranged above the sliding frame 22, and a plurality of evenly distributed positioning columns 231 are installed at the lower end of the waist-shaped plates 232. The lower end of the positioning column 231 slides through the upper frame wall of the sliding frame 22. A plurality of evenly distributed positioning holes 233 are opened on the left and right sides of the rectangular plate 21, and the lower end of the positioning column 231 is plugged into the corresponding positioning hole 233.

[0039] During specific operation, according to the width of the support reinforcement plate required for clamping and limiting, the two sliding frames 22 are slid in sequence, and the sliding frame 22 slides on the rectangular plate 21. When the sliding frame 22 moves to the required position, multiple positioning columns 231 are passed through the upper frame wall of the sliding frame 22 through two waist-shaped plates 232 and inserted into the corresponding positioning holes 233 to achieve limiting and fixing of the sliding frame 22.

[0040] See also Figure 1 , Figure 2 and Fig. 9 The automobile support reinforcement plate stamping and shaping fixture also includes a supporting device 3, which is provided with two supporting devices 3 and is symmetrically connected to the upper ends of the corresponding two sliding frames 22. The supporting device 3 includes an L-shaped plate 31 installed on the upper end of the sliding frame 22. Two circular through holes 32 are symmetrically opened on the vertical section of the L-shaped plate 31. The two circular through holes 32 on the vertical section of the same L-shaped plate 31 are commonly connected with a shaping mechanism 33.

[0041] During specific operation, the two sliding frames 22 move while driving the two L-shaped plates 31 to move, so that the distance between the two L-shaped plates 31 matches the width of the support reinforcement plate.

[0042] See also Figure 1 and Figure 2 The automobile support reinforcement plate stamping and shaping fixture also includes a clamping device 4, which is provided with two clamping devices 4 and is symmetrically connected to the upper ends of the corresponding two sliding frames 22 front and back. The clamping device 4 includes a first hydraulic push rod 41 installed on the upper end of the sliding frame 22 through a push rod seat and located on the back side of the L-shaped plate 31. The end of the first hydraulic push rod 41 close to the L-shaped plate 31 is installed with a U-shaped plate 42 with an opening facing the L-shaped plate 31, and a guiding mechanism 43 connected to the sliding frame 22 is provided at the opening of the U-shaped plate 42.

[0043] See also Figure 1 , Figure 2 and Figure 5 The guiding mechanism 43 includes a U-shaped frame 431 which is installed at the upper end of the sliding frame 22 with its opening facing downward, and a plurality of evenly distributed guide wheels 432 are rotatably connected to the lower end of the horizontal section of the U-shaped frame 431.

[0044] During specific operation, the two first hydraulic push rods 41 are connected to an external hydraulic pump. When the two sliding frames 22 move, they also drive the two U-shaped frames 431 to move synchronously. The two U-shaped frames 431 drive multiple guide wheels 432 to move, so that the multiple guide wheels 432 on the front and rear sides match the width of the support reinforcement plate. Then, the support reinforcement plate is placed on the upper end of the horizontal section of the two L-shaped plates 31, and the support reinforcement plate is located between the guide wheels 432 on both sides. The guide wheels 432 on both sides guide the movement of the support reinforcement plate and reduce the friction resistance.

[0045] See also Figure 1 , Figure 5 and Fig. 9 A limiting mechanism 34 is connected to the L-shaped plate 31, and the limiting mechanism 34 includes a moving block 341 that slides through the vertical section of the L-shaped plate 31, and the moving block 341 is L-shaped. The end of the horizontal section of the moving block 341 is located between the two L-shaped plates 31 and is integrally formed with a semi-cylindrical protrusion. A connecting spring 342 is installed between the vertical section of the moving block 341 and the vertical section of the L-shaped plate 31. A guide rod 343 is installed at the left end of the moving block 341, and a barrier branch chain 344 is connected to the end of the guide rod 343 away from the moving block 341.

[0046] See also Figure 1 , Fig. 9 and Fig.10 The blocking branch chain 344 includes a sliding groove 3441 opened on the vertical section of the L-shaped plate 31, and a sliding block 3442 is slidably connected in the sliding groove 3441. A waist-shaped through hole 3443 inclined toward the corresponding U-shaped plate 42 is opened in the middle of the sliding block 3442. The waist-shaped through hole 3443 is slidably matched with the guide rod 343. A limiting column 3444 is installed on the upper end of the sliding block 3442. The upper end of the limiting column 3444 slides through the horizontal section of the L-shaped plate 31. A limiting spring 3445 is installed between the upper end of the sliding block 3442 and the lower end of the horizontal section of the L-shaped plate 31.

[0047] When working, the guide rod 343 is initially located at the bottom of the waist-shaped through hole 3443, and the limit spring 3445 drives the limit column 3444 to penetrate the horizontal section of the L-shaped plate 31 through the sliding block 3442, and then the support reinforcement plate placed on the two horizontal sections of the L-shaped plate 31 is moved toward the two limit columns 3444 until the inclined outer side surface of the support reinforcement plate is in close contact with the limit column 3444 (such as Fig.10 As shown), the limiting column 3444 accurately limits the support reinforcement plate.

[0048] See also Figure 1 , Figure 5 and Figure 6 A clamping mechanism 44 is connected to the guiding mechanism 43, and the clamping mechanism 44 includes a connecting plate 441 installed at the upper end of the horizontal section of the U-shaped frame 431, and two guide rods 442 symmetrically distributed on the left and right are slidably penetrated and connected to the connecting plate 441, and a clamping plate 443 is commonly installed at the lower ends of the two guide rods 442, and two telescopic springs 444 sleeved on the outer periphery of the guide rods 442 are installed between the clamping plate 443 and the connecting plate 441, and a distance-adjusting branch chain 445 is installed in the middle of the upper end of the connecting plate 441.

[0049] See also Figure 5 and Figure 6 The adjustable distance branch chain 445 includes a rectangular frame 4451 installed in the middle of the upper end of the clamping plate 443, and a lifting rod 4452 is slidably connected in the rectangular frame 4451. The lifting rod 4452 is provided with a plurality of limiting through holes 4453 evenly distributed from top to bottom, and a support plate 4454 is inserted into any one of the limiting through holes 4453. The support plate 4454 slides horizontally through the frame wall of the rectangular frame 4451, and a lower pressing block 4455 that slides through the connecting plate 441 is installed on the upper end of the lifting rod 4452. The upper end of the lower pressing block 4455 is provided with an inclined surface, and the upper end of the lower pressing block 4455 is also rotatably connected with a plurality of evenly distributed rotating rollers.

[0050] See also Figure 5 and Figure 6 The upper horizontal section end of the U-shaped plate 42 is provided with a slope, and the slope cooperates with the inclined surface on the lower pressing block 4455.

[0051] During specific operation, initially, the two rectangular frames 4451 are slid in sequence according to the thickness of the support reinforcement plate. After the rectangular frame 4451 slides to the corresponding position on the lifting rod 4452, the support plate 4454 is plugged into the rectangular frame 4451 and plugged into the corresponding limiting through hole 4453, so as to limit and fix the rectangular frame 4451. After the support reinforcement plate is tightly attached to the limiting column 3444, the two first hydraulic push rods 41 are started. The two first hydraulic push rods 41 drive the two U-shaped plates 42 to move in the direction of the two lower pressing blocks 4455. The slope on the U-shaped plate 42 is aligned with the slope on the corresponding lower pressing block 4455. After the inclined surfaces contact and push each other, the lower pressing block 4455 is subjected to the downward pushing force and drives the rectangular frame 4451 to move downward through the lifting rod 4452 and the support plate 4454. The rectangular frame 4451 drives the clamping plate 443 to move downward and press on the upper end of the support reinforcement plate. The two guide rods 442 guide the movement of the clamping plate 443. When the clamping plate 443 moves, the two telescopic springs 444 are stretched. The two clamping plates 443 clamp and limit the support reinforcement plate. At this time, the horizontal section end of the lower side of the U-shaped plate 42 contacts the molding mechanism 33, closing the two first hydraulic push rods 41.

[0052] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The automobile support reinforcement plate stamping and shaping fixture also includes a stamping device 5, which is arranged above the two L-shaped plates 31. The stamping device 5 includes a stamping head 51 arranged above the two L-shaped plates 31, and the stamping head 51 is provided with two cylindrical through holes 52 symmetrically distributed on the left and right.

[0053] See also Figure 1 , Figure 2and Figure 5 The punching device 5 further includes a second hydraulic push rod 53 installed at the upper end of the punching head 51 , and a fixing plate 54 is installed at the upper end of the second hydraulic push rod 53 .

[0054] During specific operation, the fixed plate 54 is initially installed on the mounting frame at the existing working position, and the second hydraulic push rod 53 is connected to the existing hydraulic pump. After the two pressing plates 443 press and limit the support reinforcement plate, the second hydraulic push rod 53 is started, and the second hydraulic push rod 53 drives the punch head 51 to move downward. After the punch head 51 contacts the support reinforcement plate, it punches and bends the support reinforcement plate (such as Fig.11 As shown in the figure, during the bending process, the downward bent part of the support reinforcement plate pushes the corresponding moving block 341, and the moving block 341 drives the corresponding guide rod 343 to move in the waist-shaped through hole 3443 and push the waist-shaped through hole 3443. The waist-shaped through hole 3443 is subjected to force to drive the sliding block 3442 to move downward, and the sliding block 3442 drives the limiting column 3444 to move downward and stretches the limiting spring 3445. At this time, the upper end of the limiting column 3444 is flush with the horizontal section of the L-shaped plate 31, thereby releasing the limiting column 3444 from limiting the support reinforcement plate.

[0055] See also Figure 1 , Figure 2 , Figure 5 , Figure 7 and Fig. 9 The molding mechanism 33 includes a return spring 331 installed at one end of the vertical section of the L-shaped plate 31 close to the corresponding U-shaped plate 42, and a strip plate 332 is installed at the end of the return spring 331 away from the L-shaped plate 31, and two left-right symmetrically distributed threaded columns 333 are installed at one end of the strip plate 332 close to the return spring 331, and a molding screw sleeve 334 is threadedly connected to the threaded column 333, and the molding screw sleeve 334 is provided with different specifications.

[0056] During the specific operation, initially, according to the diameter of the circular hole on the bent part of the support reinforcement plate, a plastic screw sleeve 334 of corresponding specifications is selected and threadedly connected to the threaded column 333. After the support reinforcement plate is stamped and bent, the two first hydraulic push rods 41 are started, and the two first hydraulic push rods 41 drive the two U-shaped plates 42 to continue to move. The horizontal section on the upper side of the U-shaped plate 42 slides on the horizontal plane at the upper end of the lower pressing block 4455. The rotating roller at the upper end of the lower pressing block 4455 is used to reduce the U-shaped plate 42. The horizontal section on the lower side of the U-shaped plate 42 pushes the strip plate 332, the return spring 331 is compressed, and the strip plate 332 drives the corresponding threaded column 333 and the plastic screw sleeve 334 to move. The plastic screw sleeve 334 slides in the corresponding circular through hole 32 and enters the circular hole on the bent part on the corresponding side of the support reinforcement plate until it moves into the cylindrical through hole 52. During the movement of the plastic screw sleeve 334, the hole slightly deformed during the bending process of the support reinforcement plate is reshaped. The two first hydraulic push rods 41 then drive the two U-shaped plates 42 to reset, and the telescopic spring 444 in the stretched state drives the pressing plate 443 to reset upward, and the strip plate 332 is reset by the resilience of the reset spring 331, thereby releasing the limit on the support reinforcement plate, and the second hydraulic push rod 53 drives the punch head 51 to reset upward, and then the unprocessed support reinforcement plate is placed on the two L-shaped plates 31, and the unprocessed support reinforcement plate is pushed, and the unprocessed support reinforcement plate will be bent. The support reinforcement plate 341 is pushed away and moves to the bottom of the punching head 51. During this process, the bent support reinforcement plate is separated from the two moving blocks 341. The moving block 341 and the guide rod 343 are reset by the rebound force of the connecting spring 342. The limiting column 3444 is reset upward by the rebound force of the limiting spring 3445. The two limiting columns 3444 limit the unprocessed support reinforcement plate again, and then the previous support reinforcement plate stamping steps are repeated until all the support reinforcement plates are stamped.

[0057] It should be noted that after the punch head 51 is reset upward away from the bent support reinforcement plate, before the bent support reinforcement plate is separated from the moving block 341, the rebound force of the connecting spring 342 acting on the moving block 341 will not cause additional deformation of the bent support reinforcement plate.
