Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a punching machine blanking device. Background Art

[0002] A punch press is a mechanical equipment used for metal processing, usually used for stamping, forming, cutting and punching of metal materials. A punch press is usually composed of components such as a frame, a slider, a mold and a transmission system. The drive system makes the slider reciprocate on the frame to process the metal material. Punching machines are widely used in industries such as automobile manufacturing, electronic equipment manufacturing and home appliance manufacturing. It is one of the common equipment in metal processing.

[0003] After the punch press completes metal processing, the workpiece and the generated debris will remain on the processing table. Human labor is required to unload the workpiece and the debris before the next processing can be carried out. The labor intensity of unloading is large. For example, Chinese patent CN210614760U discloses a punch press blanking device, which is convenient for packing personnel to take the blanks in the collection box. However, the material dropped in the collection box contains the debris generated during the processing. It is easy to be scratched by the metal debris when taking the material, which is very unsafe. Therefore, we propose a punch press blanking device to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to provide a punching machine blanking device, which has the effects of automatically blanking and automatically screening workpieces and debris to avoid being easily scratched by metal debris when taking materials.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a punch blanking device, including a support frame, a conveying assembly installed on the support frame, a material receiving frame movably installed on the inner bottom wall of the support frame, a fixed cross plate installed on the inner side of the support frame, and a material receiving frame installed on the inner side of the support frame and extending to the right side of the support frame, the conveying assembly is also equipped with a wire screen located below the fixed cross plate, and the blanking assembly is installed on the fixed cross plate.

[0006] By adopting the above technical scheme, the processed workpieces and the generated debris automatically fall on the wire screen through the unloading component, and the conveying component drives the wire screen to rotate, so that the wire screen can drive the processed workpiece to move to the right, and automatically drop the workpiece into the receiving frame. While the wire screen drives the workpiece to drop, the debris generated in the processing process will be screened on the wire screen and fall into the receiving frame, realizing automatic dropping and automatic screening. No manual unloading is required, which reduces work intensity, automatically screens workpieces and debris, and will not be scratched by debris when storing the workpiece, which is safer.

[0007] The utility model is further configured as follows: the support frame is a U-shaped frame, and the left and right sides of the inner wall of the support frame are open.

[0008] By adopting the above technical solution, it is convenient to take out the metal scraps from the side of the support frame after the receiving frame is full of metal scraps, so as to recycle the scraps.

[0009] The utility model is further configured as follows: the conveying assembly includes two rotating shafts movably mounted on the support frame and symmetrically distributed front and back, two rotating wheels mounted on the rotating shafts, chains transmitting between the two rotating wheels on the front side and between the two rotating wheels on the rear side, and a motor mounted on the support frame for driving one of the rotating shafts to rotate.

[0010] The utility model is further configured as follows: the wire sub-screen is installed between the chains at the front and rear sides.

[0011] By adopting the above technical solution, the motor starts to drive one of the rotating shafts to rotate, and when the rotating shaft rotates, the rotating wheel rotates accordingly. The two rotating wheels on the front side and the two rotating wheels on the rear side can drive the chain to rotate, thereby driving the wire screen to rotate, so that the wire screen can not only screen and drop the debris generated by processing, but also transport the processed workpiece to the right to the receiving rack to complete the dropping.

[0012] The utility model is further configured as follows: a buffer pad is installed on the inner wall of the material receiving rack away from the support frame, the inner wall of the material receiving rack close to the wire screen is inclined, and the upper edge of the material receiving rack is located below the wire screen.

[0013] By adopting the above technical solution, the buffer pad can reduce the impact of the processed workpiece on the receiving rack when falling. The inclined design can make the screened workpiece fall more smoothly. The upper edge of the receiving rack is located below the wire screen to ensure that there is enough space for the workpiece to fall into the inside of the receiving rack.

[0014] The utility model is further configured as follows: the blanking assembly includes two connecting columns installed on the top of the fixed horizontal plate, a processing table hinged between the connecting columns on the front and rear sides, and a cylinder installed between the processing table and the fixed horizontal plate.

[0015] By adopting the above technical solution, the cylinder is started, pushing the left side of the processing table to lift up, and the right side of the processing table to tilt downward, so that the workpieces and debris scattered on the processing table can automatically fall on the wire screen for screening and dropping.

[0016] The utility model is further configured as follows: metal bristles in contact with the iron wire screen are installed at the bottom of the fixed horizontal plate.

[0017] By adopting the above technical solution, the wire screen repeatedly rotates in a circumferential direction with the chain, continuously dropping debris and workpieces. During the rotation process, the wire screen will continuously rub against the metal bristles, avoiding clogging of the wire screen after the debris is screened and dropped, thereby ensuring that the wire screen has a good screening and dropping effect on the debris.

[0018] The utility model is further configured as follows: a stabilizing component is further provided between the processing table and the fixed horizontal plate.

[0019] By adopting the above technical solution, the stabilizing component strengthens the connection between the processing table and the fixed cross plate, so that the workpiece can be placed on the processing table for processing more stably.

[0020] The utility model is further configured as follows: the stabilizing assembly comprises a support rod installed at the bottom of the processing table, a support seat installed at the top of the fixed horizontal plate, and a support groove opened on the support seat.

[0021] The utility model is further configured as follows: a rubber gasket is installed in the support groove, and the bottom of the support rod extends to the support groove and is tightly attached to the rubber gasket.

[0022] By adopting the above technical solution, the support rod extends into the support groove, so that the support seat supports the support rod, which can improve the stability of the connection between the processing table and the fixed horizontal plate, and facilitate the placement of the workpiece on the processing table for processing.

[0023] The beneficial effects of the utility model are as follows: the processed workpieces and the generated debris automatically fall on the wire screening net through the unloading component, and the conveying component drives the wire screening net to rotate, so that the wire screening net can drive the processed workpieces to move to the right, and the workpieces are automatically dropped into the receiving frame. While the wire screening net drives the workpieces to drop, the debris generated in the processing process will be screened on the wire screening net and fall into the receiving frame, realizing the automatic dropping and the effect of automatic screening, without the need for manual unloading, reducing the work intensity, automatically screening the workpieces and debris, and the workpieces will not be scratched by the debris when being stored, which has higher safety.
