Description

Technical Field

[0001] This utility model relates to the field of stamping bending technology, and in particular to a bending device for automotive stamping parts. Background Technology

[0002] In the automobile manufacturing process, some parts are directly stamped into automobile parts, while others need to undergo welding, machining, painting, or other processes after stamping before they can become automobile parts. As one of the key pieces of equipment, the performance of the stamping bending device directly affects the production efficiency, quality, and cost of automobile parts.

[0003] By comparing a metal stamping bending machine with patent publication number CN221909197U, in this solution, the electric push rod operates, which drives the clamping plate to extend. Two sets of opposing clamping plates clamp the metal parts on the support. The cylinder starts, which drives the bending head under the mounting seat to stamp and bend the metal parts on the support. However, when the bending head bends the metal parts, the bending point of the metal parts will deform, causing the two sides of the metal parts to dent towards the middle. As a result, the two sides of the metal parts will move towards the middle. At this time, the bending head only presses and bends the metal parts, which cannot achieve the effect of pressing and fixing the two sides of the metal parts. This may lead to uneven pressure on the two ends of the metal parts, which may cause the displacement of the two sides of the metal parts to be inconsistent when they move. This may lead to a change in the bending position of the metal parts after bending, resulting in inaccurate bending position, reduced bending accuracy, and reduced bending quality.

[0026] like Figures 1-5 As shown, an automotive stamping bending device includes a base plate 100 and a bending mechanism for bending automotive stampings, the bending mechanism being located above the base plate 100.

[0027] In this embodiment: the bending mechanism includes a bending platform 201 disposed on the upper end of the base plate 100.

A guide rod 223 is provided between 05, and a limit spring is connected to the outside of the guide rod 223. A bending plate 207 is installed at the center of the bottom end of the lifting plate 206. The bending plate 207 is V-shaped. The bottom end of the bending plate 207 is provided with a support structure for supporting the bending part of the plate after bending. The two sides of the bottom end of the lifting plate 206 are provided with pressing structures for pressing and fixing the plate. A cleaning structure is provided below the bending groove 202 for cleaning the waste residue on the inner wall of the bending groove 202.

[0028] The pressing structure includes movable slides 215 on both sides of the bottom end of the lifting plate 206. A sliding frame 216 is slidably installed inside the movable slide 215. A telescopic rod 217 is provided between the sliding frame 216 and the movable slide 215. A telescopic spring is connected to the outside of the telescopic rod 217. A pressing frame 218 is slidably installed inside the sliding frame 216. A compression spring is connected between the pressing frame 218 and the sliding frame 216. Multiple ball bearings 222 are rotatably installed on the surface of the bending platform 201. A rubber layer is attached to the bottom end of the pressing frame 218. An adsorption structure for adsorbing the plate is provided at the bottom end of the pressing frame 218.

[0029] The adsorption structure includes a vacuum generator 219 disposed inside the pressure frame 218. A suction chamber 220 is provided at the bottom of the pressure frame 218. A suction pipe is connected between the suction chamber 220 and the vacuum generator 219. Multiple suction holes 221 are provided at the bottom of the suction chamber 220. A soft suction cup is installed at the bottom of the suction hole 221.

[0030] The supporting structure includes a vertical groove 208 at the bottom of the bent plate 207, a top plate 209 slidably installed inside the vertical groove 208, a pre-tension spring connecting the top plate 209 and the vertical groove 208, the bottom of the top plate 209 being arc-shaped, horizontal grooves 210 on both sides of the vertical groove 208, a partition plate 211 fixed inside the horizontal groove 210, a push plate 213 on the side of the partition plate 211 near the top plate 209, and a pressing plate 212 on the side of the partition plate 211 away from the top plate 209, the pressing plate 212 being fixedly connected to the push plate 213, both the pressing plate 212 and the push plate 213 being slidably connected to the horizontal groove 210, a compression spring connecting the pressing plate 212 and the partition plate 211, a connecting plate 214 fixed on the end of the top plate 209 near the push plate 213, the connecting plate 214 and the push plate 213 being inclined on the side close to each other, and the pressing plate 212 being inclined on the side away from the partition plate 211.

[0031] The cleaning structure includes a fixed base 224 fixedly installed at the bottom of the bending groove 202. The fixed base 224 has two symmetrically arranged receiving grooves 225 in the left-right direction. Multiple blowing fans 226 are installed inside the receiving grooves 225. An air blowing channel 227 is opened between the receiving grooves 225 and the side wall of the bending groove 202. A filter plate 228 is installed at the end of the air blowing channel 227. When the plate is bent by the bending mechanism, the pressing structure presses and fixes the two ends of the plate. The pressing structure moves synchronously with the two ends of the plate and provides a firm pressing and clamping force to ensure uniform pressing force on the two ends of the plate. This reduces the shaking of the plate during bending and reduces the phenomenon of inconsistent displacement when the two ends of the plate move towards the middle. In this way, the position of the plate after bending is more accurate, and the bending accuracy and bending quality are improved.

[0032] Working principle: First, the plate is placed on the surface of the bending platform 201. Then, the hydraulic cylinder 204 is activated to move the lifting plate 206 downward, bringing the bending plate 207 down. The bending plate 207 is used to bend the plate. While bending, the pressing plate 212 on the side wall of the bending plate 207 is pressed by the bending groove 202, which causes the pressing plate 212 to move the push plate 213 towards the connecting plate 214, pressing the connecting plate 214. This causes the connecting plate 214 to move the top plate 209 downward, and the top plate 209 is used to support and fix the bent part of the plate to prevent springback.

[0033] When the lifting plate 206 moves downward, it drives the pressing frame 218 downward. The bottom end of the pressing frame 218 presses and clamps the surface of the plate. At the same time, the vacuum generator 219 is activated to make the air extraction chamber 220 a vacuum state, so that the suction cups at the bottom of the multiple suction holes 221 adsorb and fix the plate, ensuring that the contact position between the plate and the pressing frame 218 remains unchanged. When the bending plate 207 bends the plate, the center of the plate is concave, causing the two ends of the plate to move towards the center. At this time, it will drive the two sliding frames 216 to move closer to the center of the plate, ensuring that there is no relative displacement between the contact surface of the sliding frames 216 and the plate. This reduces the shaking of the plate during bending, ensures uniform pressing pressure on both ends of the plate, reduces the phenomenon of inconsistent displacement when the two ends of the plate move towards the middle, and thus ensures that the position of the plate after bending is more accurate, improving the bending accuracy and bending quality.

[0034] After the sheet metal is bent, the bending plate 207 moves upward and resets. At this time, multiple blowers 226 inside the receiving groove 225 are activated, and airflow is blown onto the side wall of the bending groove 202 through the air blowing channel 227 to disperse the waste on the side wall of the bending groove 202, reduce the adhesion of waste to the side wall of the bending groove 202, and ensure that the waste will not affect the next bending of the sheet metal.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
