Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to an automatic material ejecting device for an automobile sheet metal stamping machine. Background Technique

[0002] The processing of automobile sheet metal parts generally relies on stamping technology. In order to facilitate the removal of the sheet metal after stamping, technicians in this field have designed a device that can eject the stamped sheet metal parts out of the stamping station for transportation.

[0003] An existing patent (Publication No.: CN 220144597 U) discloses an automatic material ejecting device for an automobile sheet metal stamping machine. During the process of lifting the matching part and the ejector rod by rotating the ejecting holder, the ejector rod will gradually extend out of the stamping station. For stable connection, the spiral angle of the inclined table surface remains constant. As long as the rotation speed of the rotating ejecting holder is kept stable, the lifting speed of the ejector rod per unit time will remain consistent, and the material can be ejected stably. Compared with the existing material ejecting mechanism, the ejecting holder in this scheme will not cause the ejector rod to eject the automobile sheet metal part to fly out even if the force is applied excessively, and can better assist the operator to take out the automobile sheet metal part.

[0004] However, the above technical scheme still has certain defects. After the device lifts the material, the staff needs to stop the device automatically, which requires the staff to repeat the operation many times and is extremely prone to operation errors. In this case, the processed device needs to fall into the stamping workpiece again, which will damage the sheet metal part due to collision. Moreover, the device cannot automatically move the processed sheet metal part out of the stamping workpiece, which will affect the working efficiency of the device and thus reduce it. Therefore, an automatic material ejecting device for an automobile sheet metal stamping machine is proposed. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide an automatic material ejecting device for an automobile sheet metal stamping machine to solve the technical problems raised in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an automatic material ejecting device for an automobile sheet metal stamping machine, including an overall assembly. The overall assembly includes a pneumatic box. A material ejecting and pushing assembly is arranged at the lower end inside the pneumatic box, and a cleaning assembly is arranged on one side inside the pneumatic box.

[0007] The material ejecting and pushing assembly includes an electric push rod arranged at the lower end inside the pneumatic box. One end of the electric push rod is fixedly connected with a piston plate. An activity plate is arranged above the piston plate. A fixed column is arranged at the end of the activity plate away from the piston plate. A pushing plate is arranged at the end of the fixed column away from the activity plate. One side of the upper end inside the pneumatic box is slidably connected with a multi-stage telescopic cylinder.

[0008] As an optimal technical solution for an automatic ejection device of an automobile sheet metal stamping machine of the utility model, it is characterized in that: the cleaning component includes an air guide groove arranged at the lower end of one side of the air pressure box, and the lower end of the air pressure box is provided with an air suction one-way sheet.

[0010] As a preferred technical solution of an automatic ejection device for an automobile sheet metal stamping machine of the utility model, it is characterized in that a blowing one-way sheet is provided on one side of the stamping workpiece, and a debris collection groove is provided on the other side of the stamping workpiece.

[0011] As a preferred technical solution of an automatic ejection device of an automobile sheet metal stamping machine of the utility model, it is characterized in that: the debris collection trough is slidably connected to the air pressure box, and the air pressure box is fixedly connected to the stamping workpiece.

[0012] As a preferred technical solution of an automatic ejection device of an automobile sheet metal stamping machine of the utility model, it is characterized in that: the movable plate is slidably connected to the air pressure box, and the push plate is slidably connected to the air pressure box.

[0013] As a preferred technical solution of an automatic ejection device of an automobile sheet metal stamping machine of the utility model, it is characterized in that: the movable plate is fixedly connected to the fixed column, and the fixed column is fixedly connected to the ejection plate.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] 1. The utility model moves the movable plate upward, and the fixed column and the push plate move together to push the sheet metal out of the inside of the stamping workpiece. When the movable plate moves, the multi-stage telescopic cylinder will start to move at the same time. After the push plate pushes the sheet metal out, the multi-stage telescopic cylinder pushes the sheet metal out of the stamping workpiece at the same time, which can effectively prevent the sheet metal parts that have been processed from falling into the inside of the stamping workpiece again. At the same time, it will also prevent the staff from getting injured because the stamping device falls back again when taking the parts by themselves, and the working efficiency of the equipment will be significantly improved.

[0016] 2. The utility model starts to suck air from the suction one-way piece through the negative pressure generated when the piston plate falls. When the piston plate falls, the gas will be blown out from the blowing one-way piece to start cleaning the debris generated by the stamping of the stamping workpiece. The debris in the stamping workpiece is cleaned into the debris collection groove. At this time, the staff only needs to clean the debris collection groove, which will significantly improve the work efficiency of the staff. Description of the Drawings

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0027] Next, the embodiments of the present utility model will be described according to its overall structure.

[0028] An automatic blanking device for an automobile sheet metal stamping machine, as Figures 1-5 shown, includes an overall component 100. The overall component 100 includes an air pressure box 110. A blanking and pushing component 200 is provided at the lower end inside the air pressure box 110, and a cleaning component 300 is provided on one side inside the air pressure box 110;

[0029] The blanking and pushing component 200 includes an electric push rod 210 provided at the lower end inside the air pressure box 110. One end of the electric push rod 210 is fixedly connected with a piston plate 220. An activity plate 230 is provided at the upper end of the piston plate 220. A fixed column 250 is provided at the end of the activity plate 230 away from the piston plate 220. A push plate 260 is provided at the end of the fixed column 250 away from the activity plate 230. One side of the upper end inside the air pressure box 110 is slidably connected with a multi-stage telescopic cylinder 240.

[0030] After the sheet metal part is processed, the staff starts the electric push rod 210. At this time, the electric push rod 210 drives the piston plate 220 to move. The piston plate 220 compresses the air inside the air pressure box 110, causing the activity plate 230 to move upward. The fixed column 250 and the push plate 260 move together to push the sheet metal part out of the stamping workpiece 280. When the activity plate 230 moves, the multi-stage telescopic cylinder 240 will start to move at the same time. After the push plate 260 pushes the sheet metal part out, the multi-stage telescopic cylinder 240 will push the sheet metal part out of the stamping workpiece 280. This can effectively prevent the processed sheet metal part from falling back into the stamping workpiece 280 again, and at the same time prevent the staff from being injured due to the stamping device falling back when taking the part by themselves, and at the same time significantly improve the working efficiency of the equipment.

[0031] Please refer specifically to Figure 1 and Figure 3 The cleaning component 300 includes an air guide groove 310 provided at the lower end on one side of the air pressure box 110. An air suction one-way piece 320 is provided at the lower end of the air pressure box 110. A gas delivery groove 270 is opened on one side of the upper end of the piston plate 220. A stamping workpiece 280 is provided at the upper end of the air pressure box 110. A blowing one-way piece 330 is provided on one side of the stamping workpiece 280, and a debris collection groove 340 is provided on the other side of the stamping workpiece 280.

[0032] When the piston plate 220 moves downward, due to the negative pressure generated when the piston plate 220 drops, it starts to suck air from the air suction one-way piece 320. When the piston plate 220 drops, it will blow the gas in the direction of the blowing one-way piece 330 to start cleaning the debris generated during stamping of the stamping workpiece 280, and clean the debris in the stamping workpiece 280 into the debris collection groove 340. At this time, the staff only needs to clean the debris collection groove 340, which will significantly improve the working efficiency of the staff.

[0033] Please refer specifically to Figure 1 and Figure 3 The debris collection groove 340 is slidably connected with the air pressure box 110, and the air pressure box 110 is fixedly connected with the stamping workpiece 280.

[0034] When the debris collection tank 340 needs to be cleaned, the staff only needs to take it out from the air pressure tank 110 for cleaning, thus making the cleaning of the debris collection tank 340 more convenient.

[0035] Please refer specifically to Figure 2 and Figure 5 , the movable plate 230 is slidably connected to the air pressure tank 110, the pushing plate 260 is slidably connected to the air pressure tank 110, the movable plate 230 is fixedly connected to the fixed column 250, and the fixed column 250 is fixedly connected to the pushing plate 260.

[0036] The pushing plate 260 can better push out the sheet metal parts after processing, making it more convenient to take them.

[0037] During use, after the sheet metal parts are processed, the staff starts the electric push rod 210. At this time, the electric push rod 210 drives the piston plate 220 to move. The piston plate 220 squeezes the air inside the air pressure tank 110, causing the movable plate 230 to move upward. The fixed column 250 and the pushing plate 260 move together to push the sheet metal parts out of the stamping workpiece 280. When the movable plate 230 moves, the multi-stage telescopic cylinder 240 will start to move simultaneously. After the pushing plate 260 pushes out the sheet metal parts, the multi-stage telescopic cylinder 240 will push the sheet metal parts out of the stamping workpiece 280 at the same time. This can effectively prevent the situation where the processed sheet metal parts fall back into the stamping workpiece 280 again, and at the same time prevent the situation where the staff is injured due to the stamping device falling back again when taking the parts by themselves. At the same time, the working efficiency of the equipment will be significantly improved. When the piston plate 220 moves downward, due to the negative pressure generated when the piston plate 220 falls, it starts to suck air from the air intake one-way piece 320. When the piston plate 220 falls, it will blow the gas in the direction of the air blowing one-way piece 330 to start cleaning the debris generated during stamping of the stamping workpiece 280, and clean the debris in the stamping workpiece 280 into the debris collection tank 340. At this time, the staff only needs to clean the debris collection tank 340, which will significantly improve the working efficiency of the staff. The parts not involved in this device are the same as or can be implemented using the prior art.

[0038] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations without creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
