Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile parts processing, in particular to a feeding and loading mechanism for automobile sheet metal parts. Background Art
[0002] In modern automobile manufacturing, the production of sheet metal parts is a key process, especially in the production process of body structural parts, stamping technology plays an important role. The traditional sheet metal stamping process usually relies on a fixed position mold for single stamping. Although this method is simple, it has the problems of low production efficiency and insufficient utilization of metal plates. In order to solve these problems, a sheet metal feeding and loading mechanism based on a combination of a mobile mechanism and a hydraulic stamping device has been developed. The device adopts an advanced automatic control system, and through the cooperation of the mobile mechanism, the position of the metal plate in the stamping process can be accurately adjusted and changed. Specifically, during the stamping process, the metal plate is continuously changed in position by the drive of the mobile mechanism, so that the stamping die can stamp out multiple circular metal blocks in sequence at multiple positions, thereby maximizing the use efficiency of the metal plate. The circle is a common and easy-to-process geometric shape, which is widely used in many industrial fields. Many automotive parts such as wheels, connectors, seals, gaskets, etc. require round metal blocks.
[0003] Relying on the existing automatic loading and stamping device, as many circular metal blocks as possible can be produced on the metal plate raw material. This is because through the precise control of the computer, the adjacent stamping holes are arranged closely, which minimizes the remaining metal plate waste after the stamping is completed. It is based on the principle of making full use of the raw metal plate that the stamping of the circular metal block should be carried out closely along the edge of the metal plate. In the stamping process, the metal plate must be fixed because it needs to be continuously moved. The fixing mechanism usually used is a hydraulic clamp, but because the clamp must clamp the edge position of at least one side of the metal plate, the position where the clamp contacts the metal plate is blocked and cannot be stamped.
[0004] In order to solve the problem that the contact position between the clamp and the metal plate cannot be punched, the existing method of manually turning over the metal plate is mostly adopted, that is, first punching the end of the metal plate away from the clamp, and then manually turning over the metal plate and re-fixing it. This method is inefficient and has certain safety hazards. Another method is to set a pop-up mechanism on the processing table. After completing the processing on one end of the metal plate, the metal plate is popped up by the pop-up mechanism to complete the flipping and automatically fix it. This method is only applicable to metal plates of smaller size, but not to metal plates of larger size and weight. Summary of the invention
[0005] The present invention intends to provide a feeding and loading mechanism for automobile sheet metal parts to solve the problems raised in the above-mentioned background technology. This scheme clamps and fixes the ends of both sides of the metal plate through a pair of rotatable clamps. Through this clamping method, the metal plate can be turned over with the clamping part as the axis, and then the hydraulic clamp can change the clamping position of the metal plate in conjunction with the push of the push plate to the metal plate, thereby avoiding the situation where the clamping position is blocked and cannot be stamped, so that the entire surface of the metal plate can be stamped evenly, thereby maximizing the utilization rate of the metal plate. The entire turning process is fully automated and does not require manual intervention. While improving the processing accuracy, the safety of workers is guaranteed.

DETAILED DESCRIPTION
[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments: like Figure 1 , 2A feeding and loading mechanism for automobile sheet metal parts shown in 5 comprises a punching machine 1, a punching base 2 and a transmission platform 3, wherein a punching head is connected to the bottom end of the punching machine 1, the punching machine 1 is arranged directly above the punching base 2, the top end of the punching base 2 is arranged as a flat surface, and a punching hole for use with the punching head is opened at the top end of the punching base 2, the transmission platform 3 is arranged on one side of the punching base 2, and a bearing platform 4 is connected to the transmission platform 3, and a processing platform 5 is connected to the bearing platform 4, the processing platform 5 and the upper surface of the punching base 2 are at the same horizontal position, and a pair of symmetrical hydraulic clamps 7 are arranged on the processing platform 5, the hydraulic clamps 7 are rotatably connected to the processing platform 5, the processing platform 5 is connected to a first servo motor 9, and the output end of the first servo motor 9 is connected to one of the hydraulic clamps 7, the end of the processing platform 5 away from the punching base 2 is connected to an extension bracket 11, a push plate 12 is slidably connected to the extension bracket 11, and a driving component for driving the push plate 12 to move is arranged on the extension bracket 11.
[0016] The existing sheet metal feeding and loading mechanism based on the combination of a moving mechanism and a hydraulic stamping device adopts an advanced automatic control system. Through the cooperation of the moving mechanism, the precise adjustment and change of the position of the metal plate during the stamping process are realized. During the stamping process, the metal plate is continuously changed in position by the drive of the moving mechanism, so that the stamping die can stamp out multiple circular metal blocks in sequence at multiple positions, thereby maximizing the use efficiency of the metal plate. It is based on the principle of making full use of the raw metal plate that the stamping of the circular metal block should be carried out closely along the edge of the metal plate. In the stamping process, since the metal plate needs to be continuously moved, the metal plate must be fixed. The fixing mechanism commonly used is a hydraulic clamp, but since the clamp must clamp the edge position of at least one side of the metal plate, the position where the clamp contacts the metal plate is blocked and cannot be stamped.
[0017] In this solution, the raw metal plate to be processed is placed on the top of the processing platform 5, and the metal plate is clamped and fixed by a pair of hydraulic clamps 7. Different from the existing device that only clamps one side of the metal plate, this solution sets a pair of hydraulic clamps 7 to clamp the ends of both sides of the metal plate respectively, and the edge of the metal plate away from the end of the processing platform 5 is overlapped on the top of the stamping base 2. Through the downward pressure of the punching machine 1, the metal plate can be stamped by the punching head, and the stamping base 2 supports the metal plate. The movement of the punching machine 1 is usually achieved through a hydraulic structure. In this solution, the carrying platform 4 can be moved laterally based on the transmission platform 3, and the processing platform 5 can be moved longitudinally based on the carrying platform 4. The position of the metal plate is adjusted through the precise control of the computer, so that the punching machine 1 can punch out metal blocks along the entire surface of the metal plate in sequence. An electric drive system is installed between the carrying platform 4 and the transmission platform 3, and between the processing platform 5 and the carrying platform 4. It is the most common device for moving the processing platform, including using an electric motor to provide power. The transmission device drives the platform, and the platform is precisely controlled through the control system. Its specific working principle is a common technical means in the field, which has been well known and widely used by technical personnel in this field, so it will not be elaborated here.
[0018] When the half of the metal plate close to the punching machine 1 is processed, the user can control the processing platform 5 to move backward to make the metal plate separate from the lower side of the punching machine 1, and then start the first servo motor 9 to drive one of the hydraulic clamps 7 to rotate, and then cooperate with the other hydraulic clamp 7 to drive the metal plate to rotate until the metal plate is turned 180° to form a Figure 5 As shown, at this time, a pair of hydraulic clamps 7 release the fixation on the metal plate, and then the user drives the push plate 12 to move on the extension bracket 11 through the driving assembly, and pushes the metal plate to move in the direction close to the stamping machine 1 through the extension bracket 11, until the edge position of the unprocessed half of the metal plate reaches the top of the stamping base 2, and then the user re-clamps and fixes the edge position of the processed half of the metal plate through the pair of hydraulic clamps 7, and then continues to stamp the unprocessed half of the metal plate. With this arrangement, the metal plate can be fully automatically flipped, and the entire surface of the metal plate can be stamped by changing the clamping position of the hydraulic clamp 7. The spacing between the pair of hydraulic clamps 7 can be customized according to the size of the metal plate, which is suitable for metal plates with larger sizes.
[0019] like Figure 3 As shown, a sinking groove 6 is opened at the upper end of the processing platform 5, and the sinking groove 6 is arranged directly below a pair of hydraulic clamps 7.
[0020] The setting of the sinking groove 6 in this solution provides space for the metal plate and the hydraulic clamp 7 to rotate, preventing the end of the metal plate from hitting the surface of the processing platform 5 during the flipping process, and providing sufficient fault tolerance.
[0021] like Figure 4 As shown, a pair of hydraulic clamps 7 are connected to a pair of clamps 8 at one end close to each other, and the pair of clamps 8 are symmetrical to each other in the vertical direction.
[0022] In this solution, a pair of clamps 8 can move relative to each other based on the hydraulic clamp 7. Such a setting can improve the clamping effect of the metal plate and the stability of the metal plate. At the same time, it ensures that when the hydraulic clamp 7 releases the clamping of the metal plate, the pair of clamps 8 can be detached from the surface of the metal plate, which helps the push plate 12 to push the metal plate smoothly.
[0023] like Figure 3 As shown, a pair of limit rods 10 symmetrical to each other in the vertical direction are arranged between a pair of hydraulic clamps 7, the two ends of the limit rods 10 are respectively connected to the pair of hydraulic clamps 7, the clamp 8 is located between the pair of limit rods 10, and the upper surface of the extension bracket 11 and the processing platform 5 are at the same horizontal position.
[0024] In this solution, a pair of limit rods 10 form a connection between a pair of hydraulic clamps 7, ensuring that when the hydraulic clamp 7 connected to the first servo motor 9 rotates, the other hydraulic clamp 7 will rotate synchronously, which helps to smoothly flip the metal plate and avoid the twisting and deformation of the steel plate caused by the inconsistent rotation speed of the pair of hydraulic clamps 7. The hydraulic clamp 7 is arranged on the inner side of the limit rod 10 to ensure that the placement of the metal plate will not be affected by the limit rod 10.
[0025] The driving assembly includes a second servo motor 13 and a screw 14. The screw 14 is rotatably connected to the extension bracket 11 and is perpendicular to the processing platform 5. The second servo motor 13 is connected to the extension bracket 11, and the output end of the second servo motor 13 is connected to the screw 14. A screw sleeve for use with the screw 14 is connected to the push plate 12.
[0026] In this solution, the movement of the extension bracket 11 is driven by the second servo motor 13. When the second servo motor 13 is running, it can drive the screw 14 to rotate, and then cooperate with the screw sleeve to drive the push plate 12 to slide on the extension bracket 11. The movement direction of the push plate 12 can be controlled by changing the rotation direction of the output end of the second servo motor 13.
[0027] The specific implementation process is as follows: When in use, the user places the raw metal plate for processing on the top of the processing platform 5, clamps and fixes the ends of both sides of the metal plate through a pair of hydraulic clamps 7, and overlaps the edge of the metal plate away from the processing platform 5 on the top of the stamping base 2, then starts the punching machine 1 to press down, and the metal plate is punched by the punching head on the punching machine 1. The stamping base 2 supports the metal plate and forms a circular metal block through stamping. During the stamping process, the electric drive system is used to make the carrying platform 4 move horizontally based on the transmission platform 3, and the processing platform 5 moves longitudinally based on the carrying platform 4. Through the precise control of the computer, when the half of the metal plate close to the punching machine 1 is processed, the user controls the processing platform 5 to move backward to make the metal plate separate from the punching machine 1. , and then start the first servo motor 9 to drive one of the hydraulic clamps 7 to rotate. The hydraulic clamp 7 drives the other hydraulic clamp 7 to rotate synchronously through a pair of limit rods 10, and then drives the metal plate to rotate until the metal plate flips 180° and overlaps the extension bracket 11. At this time, the user releases the fixation of the metal plate by the pair of hydraulic clamps 7, and drives the push plate 12 to move on the extension bracket 11 through the drive assembly, and pushes the metal plate toward the direction close to the stamping machine 1 through the extension bracket 11 until the edge position of the unprocessed half of the metal plate reaches the top of the stamping base 2, and then the user re-clamps and fixes the edge position of the processed half of the metal plate through a pair of hydraulic clamps 7, and then continues to stamp the unprocessed half of the metal plate.
[0028] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
