A stamping equipment for automotive metal parts

Abstract

This utility model discloses a stamping equipment for automotive metal parts, relating to the field of stamping equipment, including: an installation device; a lower die device installed at the bottom of the installation device; and an upper die device positioned above the lower die device. The upper die device is used to stamp metal parts on the lower die device. This utility model utilizes the piston movement of the piston head to create a vacuum in the inner cavity of the adsorption plate, allowing the adsorption plate to apply negative pressure to the sheet metal parts placed on the lower die, resulting in more stable positioning of the sheet metal parts during stamping. After stamping, a return mechanism repositions the synchronous plate, causing the piston head to move towards the adsorption plate, inflating gas into the inner cavity of the adsorption plate. This airflow facilitates upward pushing of the sheet metal parts, aiding in demolding. This eliminates the need for an independent vacuum pump, reducing manual finishing costs and ensuring the processing accuracy of automotive metal parts.

Description

Technical Field

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

[0002] In the automotive manufacturing industry, the processing of metal parts (such as body sheet metal parts and chassis structural parts) generally relies on stamping technology. As core production equipment, the processing accuracy, stability, and production efficiency of stamping equipment directly determine the quality of automotive metal parts and their compatibility with the overall vehicle assembly. Automotive metal parts are mostly thin-walled and irregularly shaped. During the stamping process, it is necessary to ensure the precise fixation of the metal parts (especially sheet metal parts) on the mold. Simultaneously, after stamping, the parts must be smoothly separated from the mold (demolding). These two key aspects are crucial for ensuring stamping quality and production continuity. However, traditional stamping equipment mostly uses mechanical limiting blocks (such as positioning pins and flanges) to fix sheet metal parts. But since automotive sheet metal parts are mostly irregular curved surface structures, mechanical limiting is difficult to achieve a close fit and positioning. During the stamping process, affected by the impact force of the upper die pressing down, the sheet metal parts are prone to slight displacement or warping, resulting in out-of-tolerance dimensional deviations of the stamped parts, and even quality problems such as edge wrinkles and cracks. Additional manual labor is required for repair, increasing production costs and time. Although some equipment attempts to use vacuum adsorption positioning, the adsorption mechanism is mostly an independently driven design (such as additional vacuum pump), which requires separate control of adsorption start and stop. This not only increases the complexity of the equipment structure and energy consumption, but may also lead to poor positioning effect due to the adsorption timing not being synchronized with the upper die pressing down. Utility Model Content

[0003] The purpose of this invention is to provide a stamping equipment for automotive metal parts to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stamping equipment for automotive metal parts, comprising: Installation device; A lower mold device, wherein the lower mold device is installed at the bottom of the mounting device; An upper die device is disposed above a lower die device and is used to stamp metal parts on the lower die device.

[0005] Preferably, the mounting device includes: The base plate, wherein the lower mold device is mounted on the upper surface of the base plate; A top plate is disposed above a bottom plate, and the bottom plate and the top plate are connected by columns; A cylinder is fixedly mounted on the top plate and is used to drive the lifting and lowering movement of the upper mold device.

[0006] Preferably, the upper mold device includes: The upper mold is connected to the output end of the cylinder for transmission, and the upper mold cooperates with the lower mold device. Connecting frames, which are fixedly connected to both sides of the upper mold; The compression support leg is fixedly connected to the bottom of the connecting frame.

[0007] Preferably, the lower mold device includes: The lower mold is fixedly installed on the base plate; An adsorption mechanism and a return mechanism are installed at intervals on the top of the lower mold. The adsorption mechanism is used to adsorb and position the metal part, and the return mechanism is used to reset and support the adsorption mechanism.

[0008] Preferably, the adsorption mechanism includes: An air cylinder, which is fixedly embedded inside the lower mold; The first connecting rod, one end of which is fixedly connected to the synchronization plate; A piston head is fixedly connected to the other end of the first connecting rod, and the piston head is movably engaged with the air cylinder. An adsorption plate is fixedly connected to the top of the air cylinder, and the adsorption plate communicates with the inner cavity of the air cylinder. A plurality of pores are formed on the top of the adsorption plate.

[0009] Preferably, the return mechanism includes: The second connecting rod, one end of which is fixedly connected to the synchronization plate; The lower mold has a cavity inside, and the limiting ring is fixedly installed at the bottom of the cavity.

An extrusion disc, which is fixedly connected to the other end of the second connecting rod; A spring, which is movably sleeved on the outside of the second connecting rod.

[0010] The technical effects and advantages of this utility model are as follows: Utilizing the cooperation between the lower and upper mold devices, a cylinder drives the upper mold device to move downwards, thus stamping the metal parts placed on the lower mold device. During the downward movement of the extrusion support, the synchronous plate is pressed downwards. Connected by the first connecting rod, the piston head moves downwards synchronously with the synchronous plate. This piston movement creates a vacuum in the inner cavity of the adsorption plate, allowing the adsorption plate to apply negative pressure to the sheet metal parts placed on the lower mold, resulting in more stable positioning of the sheet metal parts during stamping. After stamping is complete, the part returns to its original position. The mechanism resets and supports the synchronous plate, causing the piston head to move towards the adsorption plate. Gas is blown into the inner cavity of the adsorption plate, and the airflow facilitates the upward pushing of the sheet metal parts to assist in demolding. No additional independent vacuum pump is required, and the adsorption action and the downward pressing action of the upper mold device are synchronized, avoiding the problems of poor fit and asynchronous independent adsorption in traditional mechanical limiting. It can effectively prevent the sheet metal parts from shifting or warping during stamping, reduce quality problems such as dimensional deviation and edge wrinkles, reduce manual finishing costs, and ensure the processing accuracy of automotive metal parts.

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.

[0015] This utility model provides, for example Figures 1-3The illustrated automotive metal part stamping equipment includes: an mounting device; a lower die device 100, which is mounted on the bottom of the mounting device; and an upper die device 200, which is disposed above the lower die device 100 and is used to stamp the metal part on the lower die device 100.

[0016] The installation device includes: a base plate 300, on which the lower mold device 100 is installed; a top plate 400, which is located above the base plate 300, and the base plate 300 and the top plate 400 are connected by a column; and a cylinder 500, which is fixedly installed on the top plate 400 and is used to drive the lifting and lowering movement of the upper mold device 200. Through the cooperation between the base plate 300 and the top plate 400, the lower mold device 100 and the upper mold device 200 are easily supported.

[0017] The upper mold device 200 includes: an upper mold 201, which is connected to the output end of the cylinder 500 and cooperates with the lower mold device 100; a connecting frame 202, which is fixedly connected to both sides of the upper mold 201; and an extrusion support 203, which is fixedly connected to the bottom of the connecting frame 202. A guide rod is fixedly installed on the upper mold 201, and the guide rod is slidably inserted into the top plate 400, thereby facilitating the limitation of the movement of the upper mold device 200 and making the lifting and lowering movement of the upper mold device 200 more stable. The upper mold 201 facilitates the stamping of sheet metal parts, the connecting frame 202 facilitates the installation of the extrusion support 203, and the extrusion support 203 facilitates the extrusion of the synchronous plate 104.

[0018] The lower mold device 100 includes: a lower mold 101, which is fixedly installed on the base plate 300; an adsorption mechanism 102 and a return mechanism 103, which are installed at intervals on the top of the lower mold 101. The adsorption mechanism 102 is used to adsorb and position the metal part, and the return mechanism 103 is used to reset and support the adsorption mechanism 102; and a synchronization plate 104, which is slidably disposed on the bottom of the lower mold 101, and the adsorption mechanism 102 and the return mechanism 103 are synchronously connected to the synchronization plate 104.

[0019] Specifically, the adsorption mechanism 102 includes: an air cylinder 121, which is fixedly embedded inside the lower mold 101; a first connecting rod 122, one end of which is fixedly connected to the synchronization plate 104; and a piston head 123, which performs piston-like movements relative to the air cylinder 121. These movements facilitate both vacuuming of the adsorption disk 124 and air injection into the inner cavity of the adsorption disk 124. The piston head 123 is fixedly connected to the other end of the first connecting rod 122. The plug 123 is movably fitted with the air cylinder 121; the adsorption plate 124 is fixedly connected to the top of the air cylinder 121, and the adsorption plate 124 communicates with the inner cavity of the air cylinder 121; the air holes 125 facilitate the uniform adsorption of sheet metal parts. Multiple air holes 125 are opened on the top of the adsorption plate 124. The cylinder 500 drives the upper mold device 200 to move downward, so as to stamp the metal parts placed on the lower mold device 100. During the downward movement of the extrusion support 203, it will press the metal parts placed on the lower mold device 100. The step plate 104 presses downwards, and under the connection of the first connecting rod 122, the piston head 123 moves downwards synchronously with the synchronous plate 104. The piston movement of the piston head 123 creates a vacuum in the inner cavity of the adsorption plate 124, allowing the adsorption plate 124 to adsorb the sheet metal parts placed on the lower mold 101 under negative pressure. This makes the position of the sheet metal parts more stable during stamping. After stamping is completed, the return mechanism 103 resets the synchronous plate 104, causing the piston head 123 to move towards the adsorption plate 124. The device moves in the direction of 24, blowing gas into the inner cavity of the adsorption plate 124. The airflow facilitates the upward pushing of the sheet metal parts to assist in demolding. No additional independent vacuum pump is required. Moreover, the adsorption action and the downward pressing action of the upper mold device 200 are synchronized, avoiding the problems of poor fit and asynchronous independent adsorption in traditional mechanical limiting. It can effectively prevent the sheet metal parts from shifting or warping during stamping, reduce quality problems such as dimensional deviation and edge wrinkles, reduce manual repair costs, and ensure the processing accuracy of automotive metal parts.

[0020] The return mechanism 103 includes: a second connecting rod 131, one end of which is fixedly connected to the synchronous plate 104; a limiting ring 132, in which a cavity is provided inside the lower mold 101, and the limiting ring 132 is fixedly installed at the bottom of the cavity, with the second connecting rod 131 slidingly engaged with the limiting ring 132; an extrusion plate 133, which is fixedly connected to the other end of the second connecting rod 131; and a spring 134, which is movably sleeved on the outside of the second connecting rod 131 and connected to the second connecting rod 131 via the second connecting rod 131. Under the connection, when the synchronous plate 104 moves downward, the extrusion plate 133 also moves downward synchronously, extruding the spring 134 and causing the spring 134 to compress and deform. When the extrusion support leg 203 stops pressing down on the synchronous plate 104, the elastic support of the spring 134 can drive the synchronous plate 104 to move upward, so as to reset the position of the synchronous plate 104 and facilitate the air inside the air cylinder 121 to be discharged through the adsorption plate 124 through the piston head 123, so as to assist the demolding of the workpiece.

[0021] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
