Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to an automatic piece-taking mechanism for a stamping die. Background Art

[0002] Stamping is a forming method that applies external force to the processing material through a press and a die to cause it to undergo plastic deformation or separation to obtain a workpiece of the desired shape and size. It is one of the important plastic processing methods with a very wide application. Stamping parts are very common in human social production and life. They are thin, uniform, light and strong. They can produce workpieces with reinforcing ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to improve their rigidity. Stamping parts have less post-processing, high production efficiency and less raw material loss. Therefore, stamping has advantages that other forming processing methods do not have. Stamping dies are crucial in stamping processing. They are called the three elements of stamping processing together with stamping equipment and stamping materials. The three elements must be combined to obtain high-quality and qualified stamping parts.

[0003] The existing stamping device has a relatively simple structure. The workpieces after stamping are taken out of the die and collected and sorted in time, which increases manpower occupation and reduces production efficiency. In addition, since the stamped parts are formed by external forces, burrs of varying degrees often appear, especially the edges of large-area stamping parts such as newly stamped sheet metal parts are often covered with burrs. At the same time, human errors are prone to occur, resulting in safety hazards or damage to parts. For this reason, we propose an automatic part removal mechanism for stamping dies. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic piece-taking mechanism for a stamping die, which can not only automatically take out the stamped workpiece and transfer it without manual transfer, thereby improving work efficiency, but also avoid workers from being harmed by burrs on the workpiece, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic part-taking mechanism for a stamping die, comprising a lower die seat and a grabbing unit;

[0006] Support seats are fixedly installed at the four corners of the lower end of the lower mold base, and a transfer platform and a storage platform are arranged on the right side of the lower mold base in sequence. Support seats are also fixedly installed at the four corners of the lower ends of the transfer platform and the storage platform. A cavity is opened in the middle of the upper end of the lower mold base, and an ejection unit is arranged below the cavity. A transfer unit is arranged above the transfer platform, and a lifting plate is arranged above the transfer unit. A fixed block is fixedly installed at the upper end of the lifting plate, and grabbing units are symmetrically arranged at both ends of the fixed block. A storage plate is fixedly installed at the upper end of the storage platform;

[0007] The grabbing unit includes a support plate, three telescopic rods and a rack. A gear is rotatably installed on the front end of the support plate, and a servo motor is fixedly installed on the rear end of the support plate. The output shaft of the servo motor passes through the support plate and is fixedly connected to the gear. The gear is meshed with the rack. The slider on the rack is slidably connected to the slide groove on the support plate. The outer ends of the rack are fixedly connected to the grabbing plate. The telescopic rod three is symmetrically installed between the grabbing plate and the support plate. The input end of the servo motor is electrically connected to the output end of the external controller.

[0008] When grasping is required, the servo motor drives the gear, and the gear drives the racks at both ends to start moving, and further drives the grasping plate to move inward, automatically picking up the workpiece after stamping, without the need for manual transfer, thereby improving work efficiency, preventing workers from being harmed by burrs on the workpiece, and ensuring the safety of workers.

[0009] Furthermore, the ejection unit includes a driving motor, a connecting block and a lead screw. The driving motor is fixedly installed on one side of the lower end of the lower die base. Rectangular grooves are symmetrically opened inside the lower die base. A lead screw is rotatably installed in one rectangular groove, and a sliding rod is fixedly installed in the other rectangular groove. An ejection plate is provided inside the cavity, and connecting blocks are fixedly connected at both ends of the ejection plate. One connecting block is threadedly connected to the lead screw, and the other connecting block is slidably connected to the sliding rod. The input end of the driving motor is electrically connected to the output end of the external controller.

[0010] When ejection is required, the drive motor rotates the lead screw, and the rotation of the lead screw drives the connecting block and the ejection plate to move upward, so that the stamped workpiece can be ejected, making it easier to remove the workpiece. The slide bar can play a guiding role during the rising process of the connecting block, reducing the friction force on the connecting block during the movement.

[0011] Furthermore, the transfer unit includes a rotating motor, a turntable and a support plate. The rotating motor is fixedly installed on the lower end of the transfer platform, and a turntable is rotatably provided on the upper end of the transfer platform. The output shaft of the rotating motor passes through the transfer platform and is fixedly connected to the turntable. The upper end of the turntable is fixedly connected to the support plate, and the input end of the rotating motor is electrically connected to the output end of the external controller.

[0012] After the ejected workpiece is clamped, the rotary motor drives the turntable to rotate 180°, and moves the clamped workpiece to the top of the placement plate at the top of the placement table. No manual transfer is required, thereby shortening the unit working hours and improving work efficiency.

[0013] Furthermore, a hydraulic cylinder is fixedly installed on the upper end of the support plate, and a telescopic rod is provided around the hydraulic cylinder. The lower end of the telescopic rod is fixedly connected to the upper end of the support plate, the upper end of the telescopic rod is fixedly connected to the lifting plate, the output end of the hydraulic cylinder is fixedly connected to the lower end of the lifting plate, a fixed block is fixedly installed on the upper end of the lifting plate, and the output end of the hydraulic cylinder is electrically connected to the input end of an external controller.

[0014] Start the hydraulic cylinder, which moves the lifting plate upwards. When it moves to a suitable position, it starts to grab the workpiece.

[0015] Furthermore, both ends of the fixed block are fixedly connected with connecting plates, an electric telescopic rod is fixedly installed on the connecting plate, the output end of the electric telescopic rod is fixedly connected to the support plate, a telescopic rod 2 is fixedly connected between the support plate and the fixed block, and the output end of the electric telescopic rod is electrically connected to the input end of the external controller.

[0016] Start the electric telescopic rod, and the electric telescopic rod starts to move with the support plate to the position of the workpiece. The telescopic rod 2 can maintain stability during the movement of the support plate.

[0017] Furthermore, damping rods are evenly installed on the inner side of the grab plate, a clamping plate is fixedly installed on the damping rod, a spring is sleeved on the damping rod, and anti-slip grooves are provided on the clamping plate.

[0018] The spring and clamping plate set at the inner end of the grabbing plate make the device more stable when picking up items, and prevent the clamping plate from clamping too tightly and causing damage to the product. The anti-slip pattern increases the friction between the clamping plate and the product, further enhancing the clamping stability, thereby making the picking process more stable and also protecting the product.

[0019] Compared with the prior art, the beneficial effects of the utility model are: the automatic part removal mechanism of the stamping die has the following advantages:

[0020] 1. When it is necessary to grab, the servo motor drives the gear, and the gear drives the racks at both ends to start moving, and further drives the grab plate to move inward, so as to automatically pick up the workpiece after stamping, and no manual transfer is required, which improves work efficiency, avoids workers from being hurt by burrs on the workpiece, and ensures the safety of workers.

[0021] 2. When ejection is required, the drive motor rotates the lead screw, and the rotation of the lead screw drives the connecting block and the ejection plate to move upward, so that the stamped workpiece can be ejected, which is convenient for picking up. The slide bar can play a guiding role during the rising process of the connecting block, reducing the friction during the movement of the connecting block.

[0022] 3. After the ejected workpiece is clamped, the rotary motor drives the turntable to rotate 180°, and moves the clamped workpiece to the top of the placement plate at the top of the placement table. No manual transfer is required, thereby shortening the unit working hours and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
