Description

Technical Field

[0001] This utility model relates to the field of burr removal technology for stamped parts, specifically a burr removal device for stamped parts. Background Technology

[0002] The burr removal device for stamped parts is a core piece of equipment in the post-processing stage of stamping. Its core function is to efficiently and accurately remove burrs, flash, and sharp edges generated during the blanking, bending, and stretching processes of stamped parts, ultimately achieving the goals of improving product quality, ensuring production safety, and optimizing the compatibility of subsequent processes.

[0003] The existing utility model patent with publication number CN222037885U discloses a burr removal device for stamped parts, relating to the field of cleaning device technology. It addresses the problem that existing cleaning devices lack a corresponding positioning structure during the grinding of stamped parts. The device includes an installation mechanism; the installation mechanism is the main body of the burr removal device, with a rectangular structure; a moving mechanism is mounted on the installation mechanism; a fixing mechanism is mounted on the top of the installation mechanism, and a contact mechanism is mounted on the fixing mechanism; a rectangular protrusion at the bottom of the sliding part is connected to the fixing part by a spring; a rotating groove is formed inside the sliding part; and a contact member is rotatably installed inside the rotating groove. Through the contact between the stamped part and the sliding part, the sliding part moves within the groove and compresses the spring. Furthermore, the side of the stamped part contacts the contact member, which has an arc-shaped structure. When in contact with the stamped part, the contact member can rotate within the rotating groove, thus better positioning the stamped part and ensuring the stability of burr removal.

[0004] During the use of the aforementioned cleaning device, burrs will be flung off during the grinding process. At the same time, due to the thinness of the stamped parts, the stamped parts may deform due to excessive clamping force during the clamping process. Furthermore, the clamping method may cause the grinding operation to be blocked by the clamping equipment at the edges of the stamped parts that are prone to burrs. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides a device for removing burrs from stamped parts. Compared with the prior art, it has the following advantages:

[0016] (1) The burr removal device for stamped parts uses a limit electric push rod to drive the piston to move inside the movable tube. The air pressure change between the piston and the stamped part generates an adsorption force, which stably fixes the stamped part on the support plate. During this process, the fixing force comes from air pressure rather than the squeezing force of mechanical clamping, and the adsorption effect is evenly applied to the bottom of the stamped part, so that the stamped part will not be deformed due to excessive local clamping force. At the same time, this fixing method does not require clamping components to be set on the edge of the stamped part. The support plate only supports the stamped part from the bottom, and the edge of the stamped part is completely exposed. With the transmission motor driving the movable tube, support plate and stamped part to rotate through the transmission belt, and the grinding motor driving the grinding plate to rotate, the rotating stamped part and the grinding plate form relative motion, which can fully cover the burr area on the edge of the stamped part, completely avoiding the obstruction of the grinding operation by the traditional clamping components, and ensuring that the grinding is thorough.

[0017] (2) In this burr removal device for stamped parts, when grinding begins, the air pump starts and draws air from inside the housing, creating a negative pressure environment inside the housing. Under the action of the air pressure difference, external air enters the housing through the gap between the top of the housing and the guide plate, forming a downward airflow. The guide plate guides the airflow direction during this process, ensuring that the airflow accurately covers the grinding area and promptly carries away the burrs and debris generated during grinding. Subsequently, the airflow carrying the debris flows downward through the filter plate. The filter holes of the filter plate can intercept the debris, causing the debris to remain above the filter plate and preventing the debris from continuing to flow with the airflow. At the same time, the housing forms a semi-enclosed space, further limiting the range of debris splashing and preventing debris from escaping from the inside of the device. Through the cooperation of the air pump, guide plate, filter plate, and housing, the collection and interception of burrs and debris are achieved, completely solving the problem of burr splashing during grinding.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a burr removal device for stamped parts includes a housing 1, and a removal mechanism 2 is provided inside the housing 1 for removing burrs from the surface of the stamped parts. The removal mechanism 2 includes:

[0025] The limiting assembly 21 includes a partition 211 fixedly installed inside the housing 1. A rubber pad 212 is fixedly installed at the center of the partition 211. A guide plate 213 is provided above the partition 211. A filter plate 214 is provided between the guide plate 213 and the partition 211. A movable tube 215 is inserted through the center of the partition 211. A support plate 216 is fixedly installed at the top of the movable tube 215. A limiting electric actuator 217 is fixedly installed inside the movable tube 215. A piston 218 is fixedly installed at the top of the limiting electric actuator 217. A drive motor 219 is fixedly installed inside the housing 1. A drive belt 2110 is sleeved on the outside of the shaft of the drive motor 219. The top of the housing 1... The part is provided with a protruding structure pointing to the center of the outer shell 1. The bottom of the movable tube 215 is a closed structure. The movable tube 215 is rotatably connected to the partition plate 211, the guide plate 213, and the filter plate 214. The support plate 216 is rotatably connected to the guide plate 213. The outer edge of the filter plate 214 is fixedly connected to the inner wall of the outer shell 1. The piston 218 is slidably connected to the movable tube 215. The bottom end of the movable tube 215 is rotatably connected to the outer shell 1 through a pressure bearing. The outer side of the movable tube 215 is provided with a groove that fits into the transmission belt 2110. One side of the transmission belt 2110 is wrapped around the outside of the shaft of the transmission motor 219, and the other side is wrapped around the outside of the movable tube 215.

[0026] Specifically, the upper surface of the support plate 216 is made of rubber, and the upper surface of the support plate 216 is lower than the top of the outer shell 1. When the stamped part is placed above the support plate 216, the bottom of the stamped part contacts the top of the movable tube 215. The piston 218 is moved by the limiting electric push rod 217. The piston 218 moves downward, which reduces the air pressure in the space between the stamped part and the piston 218, and adsorbs the stamped part above the support plate 216. The guide plate 213 can restrict the position of air entering the inner shell 1, and the filter plate 214 can restrict the position of debris to prevent debris from entering the air pump 221. The drive motor 219 can drive the movable tube 215 to rotate through the drive belt 2110, thereby driving the support plate 216 and the stamped part adsorbed above to rotate.

[0027] The grinding assembly 22 is located on the outside of the housing 1 and is used for grinding stamped parts. The grinding assembly 22 includes an air pump 221 fixedly installed on the side of the housing 1, a transmission electric push rod 222 fixedly installed on the top of the housing 1, a crossbeam 223 fixedly installed on the top of the transmission electric push rod 222, a grinding motor 224 fixedly installed at the center of the crossbeam 223, and a grinding disc 225 fixedly installed below the shaft of the grinding motor 224. The air inlet of the air pump 221 passes through the housing 1 and communicates with the inner cavity of the housing 1, and is located between the filter plate 214 and the partition plate 211. The transmission electric push rod 222 is symmetrically installed on both sides of the housing 1. The grinding motor 224 is movably connected to the housing 1 through the crossbeam 223 and the transmission electric push rod 222. The center of the grinding disc 225 and the center of the support plate 216 are not in the same vertical line.

[0028] Specifically, after the air pump 221 is started, it can extract the air inside the housing 1. The external air can enter the housing 1 through the gap between the housing 1 and the guide plate 213, and carry the debris into the housing 1. The transmission electric push rod 222 can drive the crossbeam 223 to move up and down, thereby adjusting the relative position between the grinding disc 225 and the stamping part, so that the bottom of the grinding disc 225 can contact the stamping part. The grinding motor 224 drives the grinding disc 225 to rotate to grind the stamping part.

[0029] Specifically, the limit electric actuator 217 is model KA6, the drive motor 219 is model ERNST-EM-5N / 1400, the air pump 221 is model ORUTR-LU2-10A, the drive electric actuator 222 is model lim-tec-LBP, and the grinding motor 224 is model 4036DC-T. In addition, all contents not described in detail in this specification are prior art known to those skilled in the art.

[0030] During operation, the stamped part to be processed is first placed on top of the support plate 216, with the bottom of the stamped part in contact with the top of the movable tube 215. The limit actuator 217 is activated, causing the piston 218 to slide downwards along the inner wall of the movable tube 215, creating a negative pressure between the stamped part and the piston 218. This air pressure suction force stably fixes the stamped part onto the support plate 216. Subsequently, the drive motor 219 is activated, and its shaft drives the movable tube 215 to rotate via the drive belt 2110. The movable tube 215 simultaneously rotates the top support plate 216 and the suction-held stamped part. Next, the drive electric actuator 222 is activated, which drives the top crossbeam 223 to move downwards. The crossbeam 223 drives the centrally mounted grinding motor 224 and grinding disc 225 to move downwards synchronously until the bottom of the grinding disc 225 contacts the surface of the rotating stamped part. The grinding motor 224 is then activated, driving the grinding disc 225 to rotate at high speed to grind the burrs on the edge of the stamped part. At the same time, the air pump 221 is activated, drawing air from inside the housing 1 through its air inlet. External air enters the housing 1 through the gap between the top of the housing 1 and the guide plate 213, forming an airflow. The airflow carries the burr debris generated during grinding downwards. After being filtered by the filter plate 214, the debris is intercepted above the filter plate 214, preventing debris from splashing or entering the air pump 221. After grinding is completed, turn off the grinding motor 224, the drive motor 219, and the air pump 221 in sequence. Control the limit electric push rod 217 to drive the piston 218 to move upward, release the negative pressure adsorption, and then remove the processed stamped part.
