Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a press that facilitates loading and unloading. Background Technology

[0002] A press (including punch press and hydraulic press) is a sophisticated and versatile press with a wide range of applications and high production efficiency. Presses can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. They process metal parts by applying strong pressure to metal blanks to cause plastic deformation and fracture.

[0003] When loading a press, the user needs to place the part to be processed directly into the lower mold, which is directly above the upper mold. The same applies when unloading; the processed part needs to be manually removed from the lower mold, which poses a significant safety hazard and is extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as inconvenience in loading and unloading materials and significant safety hazards, by proposing a press that facilitates loading and unloading materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A press for easy loading and unloading includes a placement frame on which a lower mold is placed. A support is fixed to the back of the top of the placement frame, and a cylinder is embedded in the support. An upper mold that cooperates with the lower mold is fixed to the piston rod of the cylinder. A loading port that cooperates with the upper mold is opened on the placement frame. An extension frame is fixed to the front of the right side of the placement frame. Auxiliary components are provided on the placement frame and the extension frame.

[0007] Preferably, the auxiliary component includes a swing frame rotatably mounted on the top right side of the placement frame. One end of the swing frame has multiple sets of teeth evenly and circumferentially fixed. The right side of the placement frame is fixed with a first motor via a support plate. The output shaft of the first motor is fixed with a gear that meshes with the teeth. A second motor is fixed inside the swing frame. The output shaft of the second motor passes through the swing frame and is fixed to the lower mold. A square frame is fixed to the back of the lower mold. One side of the extension frame is rotatably mounted with two sets of striking plates that cooperate with the square frame in the up-down direction. The bottom of each set of striking plates has multiple sets of springs fixed in the front-back direction, and one end of the springs is fixed to the extension frame. A collection box is placed on the front of the placement frame and is located below the extension frame.

[0008] Preferably, a side plate is fixed to the left side of the front of the swing frame, and an infrared beam sensor is provided on the side of the lower mold and the side plate that are close to each other.

[0009] Preferably, a vertical plate is fixed to the right side of the top back of the placement rack, and a pressure sensor that is attached to the swing frame is embedded in the vertical plate.

[0010] Preferably, a limiting sleeve is fixed on the left side of the top of the swing frame, and an arc-shaped pressure plate is slidably arranged inside the limiting sleeve, with the bottom of the arc-shaped pressure plate attached to the swing frame. Both ends of the arc-shaped pressure plate are fixed with mounting columns whose bottom ends are fixed on the placement frame.

[0011] Preferably, a slanted baffle is fixed on the right side of the top front of the extension frame and the slanted baffle is located above the striking plate.

[0012] Preferably, a protrusion is fixed to the bottom of the front side of the placement frame, and the right side of the protrusion is attached to the collection box. A receiving frame for use with the discharge port is placed at the bottom of the inner cavity of the placement frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This press, which facilitates loading and unloading, utilizes auxiliary components and a first motor as the drive source. Through the meshing of teeth and gears, the positions of the swing frame and lower die can be altered to detach the lower die from below the upper die, making it easier for the user to load materials onto the upper die and improving loading safety. Simultaneously, a second motor drives the lower die to rotate, and the elastic rebound of springs continuously provides support to the striking plates. As the lower die rotates, the frame continuously impacts multiple sets of striking plates, causing vibration and facilitating the rapid emptying of internal parts into the collection bin. This fully automates the loading process, simplifying the unloading process. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example

[0021] Reference Figure 1 and Figure 3 A press for easy loading and unloading includes a placement frame 1, on which a lower mold 4 is placed. A support is fixed to the back of the top of the placement frame 1, and a cylinder 2 is embedded in the support. The piston rod of the cylinder 2 is fixed to an upper mold 3 that cooperates with the lower mold 4. The placement frame 1 has a discharge port that cooperates with the upper mold 3. An extension frame 5 is fixed to the front of the right side of the placement frame 1. An auxiliary component is provided on the placement frame 1 and the extension frame 5. The auxiliary component includes a swing frame 6 rotatably mounted on the top right side of the placement frame 1. One end of the swing frame 6 is uniformly and annularly fixed with multiple sets of teeth 7. A first motor 8 is fixed to the right side of the placement frame 1 through a support plate. The output shaft of the first motor 8 is fixed with a gear 9 that meshes with the teeth 7. A second motor 10 is fixed inside the swing frame 6. The output shaft of the second motor 10 passes through the swing frame 6. The swing frame 6 is fixed on the lower mold 4. A side plate is fixed on the left side of the front of the swing frame 6. An infrared beam sensor 17 is set on the side of the lower mold 4 and the side plate that are close to each other. By setting the infrared beam sensor 17, the horizontal state of the lower mold 4 can be monitored in real time so that the lower mold 4 can swing normally and can give an early warning when the lower mold 4 has not flipped to the horizontal state. A square frame 19 is fixed on the back of the lower mold 4. A limit sleeve 15 is fixed on the left side of the top of the swing frame 6. An arc-shaped pressure plate 14 is slidably set in the limit sleeve 15 and the bottom of the arc-shaped pressure plate 14 is attached to the swing frame 6. Both ends of the arc-shaped pressure plate 14 are fixed with mounting columns whose bottom ends are fixed on the placement frame 1. The design of the limit sleeve 15 and the arc-shaped pressure plate 14 can slide and limit the swing frame 6, which improves the stability of the swing frame 6 when it swings.

[0022] Reference Figure 2 and Figure 3Two sets of striking plates 11, which work in conjunction with the square frame 19, are installed on one side of the extension frame 5 in a vertically rotating manner. A slanted baffle 13 is fixed to the right side of the top front of the extension frame 5, and the slanted baffle 13 is located above the striking plates 11. The design of the slanted baffle 13 prevents parts from falling directly to the outside after being flipped. Multiple sets of springs 12 are fixed to the bottom of each set of striking plates 11 in a front-back direction, and one end of the spring 12 is fixed to the extension frame 5. A collection box 16 is placed on the front of the placement frame 1, and the collection box 16 is located below the extension frame 5. By setting auxiliary components, the lower mold 4 can be separated from the upper mold 3, which facilitates the user to load materials onto the upper mold 3 and improves the safety of loading materials. At the same time, it can make the lower mold 4 vibrate when it is flipped, which helps the lower mold 4 to quickly tilt its internal parts into the collection box. The material bin 16 automates the entire unloading process, facilitating material unloading. A vertical plate is fixed to the right side of the top back of the placement frame 1, and a pressure sensor 18 is embedded in the vertical plate and attached to the swing frame 6. The design of the pressure sensor 18 can determine the position of the swing frame 6 so that the swing frame 6 can rotate to the initial position, facilitating stable docking of the upper mold 3 and the lower mold 4. A controller is set on the left side of the top front of the placement frame 1. A protrusion is fixed to the bottom of the front of the placement frame 1, and the right side of the protrusion is attached to the collection bin 16. A receiving frame for use with the unloading port is placed at the bottom of the inner cavity of the placement frame 1. The protrusion can position the collection bin 16, and the receiving frame can collect the debris generated after the parts are processed in time, avoiding random scattering and increasing the difficulty of later cleaning, and can also reuse the metal debris.

[0023] In this invention, the user activates the first motor 8 via the controller. The first motor 8 drives the gear 9 to rotate. Because the teeth 7 and gear 9 mesh, the swing frame 6 and the lower mold 4 swing forward until the lower mold 4 swings ninety degrees, disengaging it from below the upper mold 3. The elastic rebound of the spring 12 provides continuous support to the striking plate 11. At this point, the user activates the second motor 10 via the controller. The second motor 10 drives the lower mold 4 to flip to the right, thereby causing the frame 19 to flip synchronously. Furthermore, during the flipping process, the square 19 will collide with the striking plate 11 one by one, thereby causing the lower mold 4 to vibrate during the flipping. The vibration force can then be used to quickly remove the processed parts stuck in the lower mold 4 and drop them into the collection box 16 for collection, making the unloading process fully automated and convenient. The user can then control the lower mold 4 to flip and reset. At this time, the lower mold 4 is away from the upper mold 3, which makes it convenient for the user to load materials and avoids safety hazards. After the loading is completed, the user only needs to use the controller to control the swing frame 6 and the lower mold 4 to swing and reset.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
