Detailed implementation manners

[0019] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0021] Refer to Figures 1-5, An open-type fixed-table press for facilitating blanking, comprising a machine base 1, a stamping table 4, a feeding slideway 8, a discharging slideway 5, a blanking assembly and a stamping assembly. A stamping table 4 is provided on the right half of the upper surface of the machine base 1. A feeding slideway 8 connected to the stamping table 4 is provided on the left half of the upper surface of the machine base 1. Two parallel strip holes 82 are provided on the feeding slideway 8. A feeding push block 9 is provided on the feeding slideway 8 above the two strip holes 82. The lower surface of the feeding push block 9 is inserted into the corresponding strip holes 82 through two first push rods 74, and the bottom ends of the first push rods 74 are installed on a pushing assembly. A row of elastic retaining columns 6 is provided near the right side of the upper surface of the stamping table 4. A blanking assembly is provided on the front side of the stamping table 4, and a discharging slideway 5 is provided on the rear side. The discharging slideway 5 is inclined downward and a discharging port 51 is provided on the side wall of the machine base 1. An inverted L-shaped mounting bracket 2 is provided on the rear side wall of the right half of the machine base 1. Two hydraulic cylinders 3 arranged downward are provided on the cross plate of the inverted L-shaped mounting bracket 2, and a horizontally arranged stamping seat 31 is provided at the end of the telescopic shaft of the hydraulic cylinder 3. The stamping seat 31 is directly above the stamping table 4.

[0022] At Figure 1 A stamping part feeding device is arranged beside the mounting box 7 on the left half of the feeding slideway 8 in []. The feeding device can be a conveying belt. A pushing structure is arranged beside the conveying belt to push the stamping part onto the feeding slideway 8. The specific structure is not described in detail here, which belongs to the existing achievable technology and is not within the protection scope of this patent. Or hold it by hand on the left half of the feeding slideway 8.

[0023] After the stamping part is fed onto the left half of the feeding slideway 8, the pushing assembly is started to move the push rod 74, thereby pushing the feeding push block 9 towards the stamping table 4 until it reaches beside the stamping table and pushes the stamping part into the stamping table 4. Then, stamping is carried out. After stamping is completed, the hydraulic cylinder 3 raises the stamping seat 31 to prepare for blanking. The blanking assembly is started to push the stamped stamping part into the discharging slideway 5 and slide out from the discharging port 51, which is convenient for unloading.

[0024] All the above-mentioned electric control devices are controlled by a controller arranged inside the machine base, which belongs to the conventional control of the punching machine and will not be elaborated here.

[0025] The material unloading assembly includes an installation box 7 and a material unloading motor 71, a first screw rod 72, a screw slider 73, a second push rod 74, a push rod limiting rod 77, a material unloading push block 75 and an acceleration push plate 76 installed in the installation box 7. The rotating shaft of the material unloading motor 71 is connected to one end of the first screw rod 72. The first screw rod 72 is sleeved with bearings near the two ends. Two screw sliders 73 spirally sleeved on the first screw rod 72 are symmetrically arranged between the two bearings on the first screw rod 72. The screw slider 73 is provided with a U-shaped joint on the side facing the stamping table 4. Two U-shaped joints are symmetrically provided on the left and right sides of the rear side of the block 75, and a second push rod 74 is correspondingly connected between the two U-shaped joints on the unloading push block 75 and the U-shaped joints on the two screw sliders 73, and both ends of the push rod 74 are rotatably connected to the U-shaped joints. Two acceleration cylinders are provided in the unloading push block 75, and the acceleration cylinder faces the stamping table 4 and fixes the acceleration push plate 76 on the acceleration cylinder shaft 761 of the acceleration cylinder. The unloading push block 75 is mounted on the edge of the stamping table 4, and the upper and lower horizontal surfaces of the two second push rods 74 are clamped and limited by two push rod limit rods 77.

[0026] When unloading, the unloading motor 71 drives the two unloading push blocks 75 to move toward each other, and pushes the two push rods 74 toward the punching table 4, thereby pushing out the unloading push block 75, slowly pushing the stamping part to the side of the unloading chute 5, and then using the acceleration cylinder to quickly push out the acceleration cylinder shaft 761, so that the acceleration push plate 76 has a rapid thrust on the stamping part, so that it enters the unloading chute 5 at a certain speed. The unloading chute 5 is a chute set downwardly inclined, and the stamping part will slide down to complete the unloading. After unloading is completed, the acceleration cylinder retracts the acceleration cylinder shaft 761, so that the acceleration push plate 76 is retracted and attached to the unloading push block 75, and then the unloading motor 71 rotates in the opposite direction to drive the two unloading push blocks 75 to move in the opposite direction, pull back the unloading push block 75, and wait for the next unloading. The push rod limit rod 77 prevents the second push rod 74 from rotating.

[0027] The maximum angle between the two push rods 74 is not greater than 120° (e.g. Figure 2 ), the minimum angle is not less than 30° (such as Figure 3 ). A degree greater than 120° facilitates the push rod to be pushed out, while a certain angle prevents the push rod from swinging.

[0028] The pushing assembly includes two synchronous motors 95, two second screw rods 94 and a pushing bar 93. A second screw rod 94 is respectively connected to the rotating shaft of the two synchronous motors 95. The two ends of the pushing bar 93 are respectively spirally sleeved on the two second screw rods 94. The second screw rod 94 is sleeved with a bearing near the two ends. The bottom end of the first push rod 92 is fixed on the pushing bar 93.

[0029] Two synchronous motors 95 drive two second lead screws 94 to rotate synchronously, so that the pushing bar 93 is pushed forward. On the contrary, when the two synchronous motors reverse, the pushing bar 93 is pulled back.

[0030] On one side wall of the feeding push block 9 facing the stamping table 4, a pushing plate 91 is embedded. There are two pushing cylinders 911 in the feeding push block 9, and the pushing plate 91 is installed on the cylinder shaft. When the feeding push block 9 cannot be sent to the stamping table, the stamping part can only retreat to the edge of the stamping table. It is necessary to push the stamping part into the inside of the stamping table 4. Then, the pushing cylinder 911 needs to push the pushing plate 91 forward for a certain distance, so that the stamping part is further pushed onto the stamping table 4 to ensure that the stamping part is pushed into the correct position.

[0031] The elastic stop post 6 is movably inserted into the stamping table 4, and a spring 61 is provided at the bottom of the elastic stop post 6. When the stamping seat presses down, if there is no stamping part, it will press on the elastic stop post 6. The spring 61 is provided to retract the elastic stop post 6 into the stamping table 4 to prevent the stamping seat from accidentally stamping on the elastic stop post 6 and being damaged.

[0032] A limiting block 81 is provided on the inner side of the left end of the feeding slideway 8. Ensure that the stamping part abuts against the limiting block 81 after being fed, and ensure that when the stamping part is pushed into the stamping table 4, it is pushed in according to the predetermined track.

[0033] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
