Description

Technical Field

[0001] The invention relates to the technical field of automobile stamping parts processing, in particular to an automobile chassis stamping parts processing device. Background Art

[0002] Automobile chassis stamping parts refer to various metal parts made by stamping process and used to form the automobile chassis structure. Automobile chassis stamping parts include transmission brackets, shock absorber brackets and engine brackets, etc. Figure 8 ) is processed by cutting the plate into a T-shaped structure through a cutting mechanism, and then punching the plate into a concave structure of the shock absorber bracket through a punching machine.

[0003] However, the following problems currently exist in the stamping process of the shock absorber bracket: 1. In the existing stamping method, the upper module is moved downward to push the plate and the lower module tightly to fix the plate, and then the upper module continues to move downward to drive the plate and the lower module downward. The plate is blocked by the blocks on both sides of the lower module and is bent into a shock absorber bracket while moving downward. However, after stamping, the bracket is easily stuck on the upper module and needs to be removed manually or by a robotic arm and removed from the stamping machine for subsequent plate processing. Both manual removal and robotic arm removal will cause interruption of the processing process and affect the efficiency of the production and processing of the shock absorber bracket. Secondly, the plate placed on the upper module requires an additional shaping mechanism to be aligned to ensure the accuracy of the shape of the stamped shock absorber bracket, but the shaping mechanism will affect the continuity of the stamping process, which in turn also affects the efficiency of the shock absorber bracket processing.

[0004] 2. If the shock absorber bracket is stamped and formed only by the block, the block will wear out quickly and affect its service life. If the edge of the block is not smooth enough, the pressure on the plate will be inconsistent, which will cause the area with excessive pressure to be crushed or over-stretched, resulting in surface scratches, cracks and even fractures. At the same time, this uneven pressure distribution can easily cause unexpected distortion of the entire plate, thereby affecting the quality of the shock absorber bracket stamping process.

[0032] 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. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. 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.

[0033] like Figure 1 As shown, a vehicle chassis stamping parts processing device includes a base 10; two limit seats 11 are symmetrically fixedly installed on the upper end of the base 10, and a stamping mechanism 2 is commonly provided on the limit seats 11 and the base 10.

[0034] like Figure 1 and Figure 2 As shown, the stamping mechanism 2 includes a column, and two columns that are symmetrical on the left and right and located between the two limit seats 11 are fixedly installed on the upper end of the base 10. A lower module 20 is installed on the two columns for sliding up and down together. A No. 1 compression spring 21 corresponding to the column is fixedly installed between the lower end of the lower module 20 and the upper end of the base 10, and the No. 1 compression spring 21 is sleeved on the corresponding pillar. Two symmetrical supporting columns are fixedly installed on the upper ends of the two limit seats 11. A top plate 22 is fixedly installed on the upper ends of the support columns. Two symmetrical limiting rods 23 are arranged on the top plate 22. The lower ends of the two limiting rods 23 slide through the top plate 22 and then an upper module 24 is fixedly installed together. A driving component is arranged on the top plate 22 for driving the upper module 24 to move downward to cooperate with the lower module 20 to extrude the fixed bracket and push the fixed plate downward to contact the limiting seat 11 to bend the bracket into shape.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, the limit seat 11 is provided with a bending portion 26 for cooperating with the upper module 24 to push and assist in bending the plate, the lower module 20 is provided with a shaping portion 27 for cooperating with the mounting hole on the plate to align and limit the plate, the upper module 24 is provided with a pushing portion 28 for driving the shaping portion 27 to move and push the formed shock absorber bracket out of the upper module 24, and the upper module 24 is provided with a discharging portion 29 for pushing the formed shock absorber bracket out of the lower module 20.

[0036] like Figure 2 As shown, the driving assembly includes a hydraulic cylinder 25 , and the hydraulic cylinder 25 is fixedly installed on the upper end of the top plate 22 . The telescopic section of the hydraulic cylinder 25 slides through the top plate 22 and is fixedly connected to the upper module 24 .

[0037] During specific operation, the external material-taking mechanism moves the cut plate to the upper end surface of the lower module 20, and then the hydraulic cylinder 25 pushes the upper module 24 to move downward. The upper module 24 first straightens the plate through the shaping part 27. As the upper module 24 continues to move downward, the upper module 24 will drive the pushing part 28 to contact the plate. Then the upper module 24 presses the plate against the lower module 20 to fix the plate. The upper module 24 continues to move downward and pushes the fixed plate and the lower module 20 to move downward, while compressing the No. 1 compression spring 21. Then the upper module 24 continues to move downward and drives the plate to contact the edge of the limit seat 11, and the plate is bent as the plate moves downward, and the plate is assisted in bending by the bending part 26 during the bending process to reduce the wear of the limit seat 11 and extend its service life, as well as to ensure the quality of the stamping process of the shock absorber bracket.

[0038] After the stamping is completed, the hydraulic cylinder 25 pulls the upper module 24 upward, and the upper module 24 and the lower module 20 maintain the squeezing and fixing of the shock absorber bracket until the No. 1 compression spring 21 is completely reset. Then, as the upper module 24 moves upward, the upper module 24 will push the shock absorber bracket through the pushing portion 28, so that the shock absorber bracket is separated from the upper module 24 and remains on the lower module 20, and the shaping portion 27 releases the limit on the shock absorber bracket, and at the same time, the bending portion 26 is reset away from the shock absorber bracket. Then, as the upper module 24 continues to move upward and reset, the shock absorber bracket will be pushed away from the lower module 20 through the discharging portion 29 to realize the unloading operation of the shock absorber bracket.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, the shaping portion 27 includes a circular groove 270, and two left-right symmetrical circular grooves 270 are provided at the upper end of the lower module 20. Four slide grooves 271 that penetrate the lower module 20 are evenly provided on the bottom wall of the inner cavity of the circular groove 270 along its circumference. The two inner walls of the slide groove 271 that are symmetrical about the radial line of the circular groove 270 are provided with inclined grooves 272 that are inclined from top to bottom toward the center of the circular groove 270. Guide columns 273 are slidably installed in the inclined grooves 272. A shaping plate 274 is fixedly installed between the two guide columns 273 in the same slide groove 271. A linkage part 4 for driving the four shaping plates 274 in the same circular groove 270 to move synchronously is provided in the circular groove 270.

[0040] like Figure 4 , Figure 5 and Figure 6As shown, the linkage part 4 includes a support 40, and the support 40 is installed for sliding up and down at one end of the shaping plate 274 close to the center of the circular groove 270, and the support 40 is installed in the circular groove 270 for radial sliding along the circular groove 270. A circular hole penetrating the lower module 20 is concentrically opened on the bottom wall of the inner cavity of the circular groove 270, and a T-shaped column 41 is arranged in the circular groove 270. The vertical section of the T-shaped column 41 is installed for sliding up and down in the circular hole, and a No. 2 compression spring 42 is fixedly installed between the lower end of the horizontal section of the T-shaped column 41 and the inner wall of the circular groove 270, and a connecting rod 43 is hinged between the horizontal section of the T-shaped column 41 and the support 40.

[0041] like Figure 5 As shown, the pushing portion 28 includes a groove 280, and the lower end of the upper module 24 is provided with a groove 280, in which a pressure plate 282 is movably installed through a No. 3 compression spring 281, and an axle column is fixedly installed on the upper end of the pressure plate 282, and the axle column is slidably installed on the upper module 24 up and down, and a through hole 283 is provided on the pressure plate 282 at a position corresponding to the circular groove 270, and a push rod 284 is fixedly installed in the groove 280, which is concentric with the through hole 283 and contacts the corresponding T-shaped column 41.

[0042] When the upper module 24 moves downward, the push rod 284 pushes the T-shaped column 41 downward, and the second compression spring 42 is compressed at the same time. The T-shaped column 41 moves downward, and the support 40 is pushed away from the corresponding T-shaped column 41 through the connecting rod 43. The support 40 pushes the shaping plate 274 to move, and the shaping plate 274 cooperates with the guide column 273 and the inclined groove 272 to make the shaping plate 274 move upward while moving away from the corresponding T-shaped column 41 until the shaping plate 274 and the plate are aligned. The inner wall of the mounting hole contacts with the plate to align and limit the plate, and the push rod 284 contacts with the T-shaped column 41 and pushes the T-shaped column 41 to move downward. At the same time, the pressure plate 282 will contact with the plate and will compress the No. 3 compression spring 281 as the upper module 24 moves downward until the upper module 24 contacts with the plate. At this time, the pressure plate 282 is located in the groove 280, and the shaping plate 274 contacts with the inner wall of the mounting hole of the plate. Then, as the upper module 24 moves downward, the plate can be punched into a shock absorber bracket.

[0043] After the stamping is completed, the upper module 24 moves upward, and the lower module 20 moves upward synchronously through the No. 1 compression spring 21, and maintains the squeezing of the shock absorber bracket until the No. 1 compression spring 21 is completely reset, and then the upper module 24 continues to move upward and will move away from the lower module 20. Under the action of the No. 3 compression spring 281, the shock absorber bracket will be pushed out of the upper module 24 through the pressure plate 282. At this time, the T-column 41 moves upward under the action of the No. 2 compression spring 42. The T-column 41 pulls the shaping plate 274 away from the inner wall of the mounting hole of the shock absorber bracket through the connecting rod 43 and the support 40, and with the cooperation of the guide column 273 and the inclined groove 272, the upper end of the shaping plate 274 is lower than the upper end of the lower module 20 to avoid interfering with the feeding and discharging of the shock absorber bracket.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the bending portion 26 includes an L-shaped groove 260, and an L-shaped groove 260 is opened at the upper end of the limit seat 11. An L-shaped plate 261 is arranged in the L-shaped groove 260. The upper end of the L-shaped plate 261 and the upper end of the limit seat 11 are located on the same horizontal plane, and the left and right ends of the transverse section of the L-shaped plate 261 are rotatably connected to the limit seat 11 through a torsion spring rod 262. The end of the torsion spring rod 262 away from the L-shaped plate 261 passes through the limit seat 11 and is fixedly installed with a support plate 263. A pushing member 3 for pushing the support plate 263 to rotate is arranged on the upper module 24.

[0045] like Figure 2 , Figure 3 and Figure 4 As shown, the pushing member 3 includes a fixed plate 30, the upper end of the upper module 24 is fixedly installed with the fixed plate 30, the lower end of the fixed plate 30 and the support plate 263 are fixedly installed with a push plate 31 at a position corresponding to each other, and the lower end of the push plate 31 is rotatably installed with a roller shaft 32 that contacts the corresponding support plate 263.

[0046] During specific operation, when the upper module 24 moves downward and drives the fixed plate to move downward, the plate will be blocked by the limit seat 11 and bend. At the same time, the fixed plate 30 will push the support plate 263 to rotate through the push plate 31 and the roller shaft 32, and the support plate 263 will drive the L-shaped plate 261 to rotate synchronously through the torsion spring rod 262, so that the plate is blocked by the limit seat 11 and pushed by the L-shaped plate 261 during the downward movement, so as to realize the stamping processing of the shock absorber bracket, thereby reducing the friction between the plate and the limit seat 11, thereby extending its service life. After the stamping is completed, the upper module 24 moves upward, and the upper module 24 drives the fixed plate 30, the push plate 31 and the roller shaft 32 to move upward, and the L-shaped plate 261 and the support plate 263 rotate and reset under the action of the torsion spring rod 262.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, the discharge portion 29 includes a notch, a notch is provided at the left end of the fixed plate 30, a slider is slidably installed in the notch, a push plate 290 is fixedly installed at the lower end of the slider, a rectangular plate 291 located at the upper end of the fixed plate 30 is fixedly installed at the upper end of the slider, an inverted plate 292 located at the right end of the rectangular plate 291 is fixedly installed at the upper end of the fixed plate 30, two front-to-back symmetrical shaft rods 293 are fixedly installed at the right end of the rectangular plate 291, the right end of the shaft rod 293 slides through the inverted plate 292, an actuator 5 for driving the push plate 290 to move is commonly provided on the rectangular plate 291 and the top plate 22, and a locking member 6 for limiting the movement of the push plate 290 is provided on the fixed plate 30.

[0048] like Figure 2 and Figure 3 As shown, the actuator 5 includes a tension spring 50, and a tension spring 50 corresponding to the shaft rod 293 and sleeved on the shaft rod 293 is fixedly installed between the rectangular plate 291 and the inverted plate 292. Inclined plates 51 are fixedly installed at both ends of the rectangular plate 291, and the inclined plates 51 are in a right-angled trapezoidal structure with an inclined surface downward. A pushing plate 52 is fixedly installed at the lower end of the top plate 22 at a position corresponding to the inclined plate 51 one by one through a support plate, and the pushing plate 52 is in a right-angled trapezoidal structure with an inclined surface upward.

[0049] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the locking member 6 includes a push rod 60, and the upper end of the inverted plate 292 is provided with the push rod 60. The lower end of the push rod 60 slides through the horizontal section of the inverted plate 292 and is fixedly installed with a support plate 61 located below the shaft rod 293. A return spring 62 is fixedly installed between the upper end of the support plate 61 and the inverted plate 292. A limiting column 63 corresponding to the shaft rod 293 is installed on the upper end of the support plate 61. A limiting hole cooperating with the limiting column 63 is opened on the shaft rod 293, and a ball is rollingly installed on the upper end of the shaft rod 293.

[0050] During specific operation, the upper module 24 moves downward to drive the fixed plate 30 to move downward synchronously. The downward movement of the fixed plate 30 causes the top rod 60, which is initially in contact with the lower end of the top plate 22 and compresses the reset spring 62, to move downward, so that the distance between the top plate 22 and the top rod 60 increases, and the reset spring 62 drives the limit column 63 to move upward, and the limit column 63 contacts the outer wall of the shaft rod 293 through the ball bearing, and then the top rod 60 moves away from the top plate 22, and the inclined surface of the inclined plate 51 contacts the inclined surface of the pushing plate 52. As the fixed plate 30 moves downward and the inclined plate The cooperation between the inclined surfaces of 51 and the pushing plate 52 pushes the rectangular plate 291 away from the upper module 24, and the rectangular plate 291 drives the pushing plate 290 away from the upper module 24 through the slider, and the movement of the rectangular plate 291 drives the shaft rod 293 to move and stretch the tension spring 50 at the same time, until the right end surface of the inclined plate 51 is opposite to the left end surface of the pushing plate 52, and the limiting hole moves to the position of the limiting column 63, and the limiting column 63 is inserted into the limiting hole under the action of the reset spring 62 to limit the movement of the shaft rod 293 and keep the tension spring 50 in a stretched state.

[0051] After the stamping is completed, the hydraulic cylinder 25 pulls the upper module 24 to move upward, so that the shaping part 27 and the bending part 26 are reset, and then the upper module 24 drives the inclined plate 51 to move upward to the top of the pushing plate 52 through the fixed plate 30 and the rectangular plate 291. Then, as the upper module 24 continues to move upward, the push rod 60 will contact the lower end of the top plate 22 and be pushed downward with the upward movement of the upper module 24. The downward movement of the push rod 60 drives the limit column 63 to disengage from the limit hole through the support plate 61 to release the restriction on the shaft rod 293. At this time, the rectangular plate 291, the slider and the push plate 290 will move quickly toward the shock absorber bracket under the action of the tension spring 50, so as to push the shock absorber bracket out of the lower module 20 through the push plate 290, thereby realizing the unloading of the shock absorber bracket after the stamping is completed, and then facilitating the subsequent feeding processing of the plate to improve the efficiency of the stamping processing of the shock absorber bracket.
