Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a blanking and sorting device for a punch press. Background Technology

[0002] In the field of machining, punch presses, as an important forming equipment, are widely used in the stamping of metal sheets. During the operation of a punch press, the blanking process is a crucial component of the entire production flow; the efficiency and quality of blanking collection directly affect the continuity of production and product quality.

[0003] Currently, most common methods for collecting workpieces from punch presses involve using simple receiving boxes to directly receive the workpieces falling from the press. However, this traditional method has many drawbacks. On the one hand, when the punch press is unloading, the workpieces may fall into the receiving box at a high speed and with great force, causing them to collide with each other. This not only easily damages the surface of the workpieces, affecting product quality, but may also cause some workpieces to bounce out of the receiving box and scatter in the work area, increasing the time and labor intensity for workers to find and collect the workpieces. On the other hand, simple receiving boxes do not have sorting functions. When the punch press processes multiple workpieces of different specifications or types, it is impossible to effectively classify the unloaded workpieces, requiring workers to manually sort them later, further reducing production efficiency and increasing labor costs. Utility Model Content

[0004] The purpose of this invention is to provide a blanking and sorting device for punch presses to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punch press unloading and sorting device, including a punch press base fixedly installed on the top of the base, a mounting frame fixedly connected to the top right side of the base, and a sorting mechanism and a reciprocating pushing mechanism respectively connected to both sides of the base;

[0006] The sorting mechanism includes a collection platform, a slide rail, a slider, a collection box, a feeding chute, and a discharge chute.

[0009] Preferably, the output shaft of the motor passes through the front of the mounting bracket and is rotatably connected to the inner wall of the mounting bracket. The upper half of the semi-tooth bracket is slidably connected to the outer surface of the cam shaft. The lower surface of the semi-tooth bracket is connected with an upper tooth, and the upper surface of the reciprocating shaft is connected with a lower tooth. The upper tooth and the lower tooth are meshed together.

[0010] Preferably, a punch frame is fixedly connected to the top of the punch press base, a motor is fixedly installed on one side of the punch frame, the output end of the motor is connected to a transmission component, a rotating shaft is connected to one side of the transmission component, a small gear is fixedly connected to the outer surface of the rotating shaft, a transmission shaft is connected to the inside of the punch frame through a bearing seat, a large gear is fixedly connected to one side of the outer surface of the transmission shaft, a cam is fixedly connected to the outer surface of the transmission shaft, a stamping seat is fixedly connected to the outer surface of the cam, and a pressure plate is fixedly connected to the bottom of the stamping seat.

[0012] Preferably, a workpiece plate is fixedly connected to the surface of the punch press frame, the surface of the workpiece plate has a stamping groove, and the blanking plate extends into the interior of the stamping groove.

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

[0014] 1. The punch press uses a material sorting device. After the material plate pushes the parts out of the stamping groove, the parts will fall into the inside of the material feeding chute. Because the width of the material feeding chute gradually increases from front to back, parts of different specifications will fall into different collection boxes. While collecting, parts of different specifications can also be sorted. After the parts in a collection box are full, the collection box can be pushed to drive the slider to slide on the surface of the slide rail, so as to facilitate the transport of the collected parts.

[0015] 2. The punch press uses a blanking and sorting device. The cam shaft rotates with the turntable. Because the half-tooth frame rotates with the cam shaft, it will continuously change direction, so that the lower tooth at its bottom will continuously rotate on the surface of the upper tooth. This causes the reciprocating shaft to move within the cage. During the movement of the reciprocating shaft, it will drive the connecting block and the blanking plate to move laterally, thereby pushing out the parts in the stamping groove and preventing the parts from accumulating in the stamping groove.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-6This utility model provides a technical solution: a punch press unloading and sorting device, including a base 1 and a punch press seat 2 fixedly installed on the top of the base 1, a mounting frame 4 fixedly connected to the top right side of the base 1, and a sorting mechanism and a reciprocating pushing mechanism respectively connected to both sides of the base 1.

[0025] The sorting mechanism includes a collection platform 5, a slide rail 501, a slider 502, a collection box 503, a discharge slide 504, and a discharge chute 505. The collection platform 5 is fixedly installed on the left side of the base 1. The slide rail 501 is fixedly installed on the top of the collection platform 5. The slider 502 is slidably connected to the surface of the slide rail 501. The collection box 503 is fixedly connected to the top of the slider 502. The discharge slide 504 is fixedly connected to the top of the punch press base 2. The discharge slide 504 is made of aluminum alloy and its surface is electroplated, making it smooth and easy for workpieces to slide. The discharge chute 505 is opened on the surface of the discharge slide 504. The inside of the collection box 503 is shaped with a lower left side and a higher right side. The side of the discharge slide 504 near the punch press base 2 is higher, and the side located at the top of the collection box 503 is lower. The width of the discharge chute 505 gradually increases from front to back.

[0026] After the part is pushed out of the stamping slot by the feeding plate 408, the part will fall into the inside of the feeding slide 504. Because the width of the discharge chute 505 gradually increases from front to back, parts of different specifications will fall into the inside of different collection boxes 503. While collecting, parts of different specifications can also be sorted. After the parts inside a collection box 503 are full, the slider 502 can be moved to slide on the surface of the slide rail 501 by pushing the collection box 503, so as to facilitate the transport of the collected parts.

[0027] The reciprocating drive mechanism includes a motor 401, a turntable 402, a cam shaft 403, a half-gear holder 404, a reciprocating shaft 405, a cage 406, a connecting block 407, and a feed plate 408. The motor 401 is fixedly mounted on the top of the mounting bracket 4. The motor 401 is a 68KTYZ AC permanent magnet synchronous motor. The turntable 402 is connected to the output end of the motor 401. The cam shaft 403 is fixedly connected to the front of the turntable 402. The half-gear holder 404 is connected to the outer surface of the cam shaft 403. The cage 406 is fixedly mounted on the top of the mounting bracket 408. On the front of the mounting bracket 4, the reciprocating shaft 405 is slidably connected to the inside of the retainer 406, the connecting block 407 is fixedly connected to the left end of the reciprocating shaft 405, the feed plate 408 is fixedly connected to the left side of the connecting block 407, the output shaft of the motor 401 passes through the front of the mounting bracket 4 and is rotatably connected to the inner wall of the mounting bracket 4, the upper half of the half toothed bracket 404 is slidably connected to the outer surface of the convex shaft 403, the lower surface of the half toothed bracket 404 is connected to the upper tooth, the upper surface of the reciprocating shaft 405 is connected to the lower tooth, and the upper tooth and the lower tooth are meshed together.

[0028] During stamping, the motor 401 is started, and the output shaft of the motor 401 drives the turntable 402 to rotate. The cam shaft 403 rotates with the turntable 402. Because the half-tooth frame 404 rotates with the cam shaft 403, it will continuously change direction, so that the lower tooth at its bottom will continuously rotate on the surface of the upper tooth. This causes the reciprocating shaft 405 to move within the retainer 406. During the movement, the reciprocating shaft 405 will drive the connecting block 407 and the blanking plate 408 to move laterally, thereby pushing the parts out of the stamping groove and preventing the parts from accumulating in the stamping groove.

[0029] The top of the punch press base 2 is fixedly connected to the punch press frame 6, and the surface of the punch press frame 6 is fixedly connected to the workpiece plate 3. The surface of the workpiece plate 3 has a stamping groove, and the blanking plate 408 extends into the interior of the stamping groove.

[0030] A motor 201, model 25GA-385 DC micro geared motor, is fixedly mounted on one side of the punch press frame 6. The output end of motor 201 is connected to a transmission component 202. A rotating shaft 203 is connected to one side of the transmission component 202. A small gear 204 is fixedly connected to the outer surface of the rotating shaft 203. One end of the rotating shaft 203 is connected to the center of the small gear 204, and the other end is connected to the center of the large pulley. Inside the punch press frame, a transmission shaft 206 is connected via a bearing housing. A large gear 205 is fixedly connected to one side of the outer surface of the transmission shaft 206. A cam 207 is fixedly connected to the outer surface of the press frame 6. A stamping seat 208 is fixedly connected to the outer surface of the cam 207. A pressure plate 209 is fixedly connected to the bottom of the stamping seat 208. The top of the pressure plate 209 is connected to the bottom of the stamping seat 208 through a detachable connecting column. The pressure plate 209 can be replaced. A large gear 205 meshes with a small gear 204. The drive shaft 206 and the rotating shaft 203 are both connected to the press frame 6 through bearing seats. Ball bearings are installed inside the bearing seats. The outer surfaces of the drive shaft 206 and the rotating shaft 203 are connected to the inner ring of the ball bearings.

[0031] The stamping rate can be controlled by controlling the rotation speed of motor 201, and the speed at which the blanking plate 408 pushes the workpiece inside the stamping groove can be controlled by controlling the rotation speed of motor 201 and motor 401. Both the rotation speeds of motor 201 and motor 401 are controlled by a PLC program, achieving the effect of the blanking plate 408 ejecting the workpiece after one stamping. The transmission component 202 includes a small pulley, a transmission belt, and a large pulley. The center of the small pulley is connected to the output end of motor 201, and the center of the large pulley is connected to one end of the rotating shaft 203. The small pulley and the large pulley are connected by the transmission belt.

[0032] Working principle: When stamping a workpiece, the workpiece is first placed on the workpiece plate 3. The motor 201 is started. The output shaft of the motor 201 drives the small pulley in the transmission component 202 to rotate. The small pulley drives the large pulley to rotate through the transmission belt. The large pulley drives the rotating shaft 203 to rotate. The rotating shaft 203 drives the small gear 204 to rotate. The small gear 204 drives the large gear 205 that meshes with it to rotate. The large gear 205 drives the transmission shaft 206 to rotate. The transmission shaft 206 drives the cam 207 on its outer surface to rotate. As a result, the cam 207 drives the stamping seat 208 to reciprocate in the vertical direction during the rotation, thereby driving the pressure plate 209 to continuously stamp the workpiece.
