Description

Technical Field

[0001] The utility model relates to the technical field of part processing, in particular to an automatic blanking mechanism for a sawing machine. Background Art

[0002] A sawing machine is a cutting tool. An annular saw band is tensioned on two saw wheels, and the saw wheels drive the saw band to perform cutting, so as to cut the curve profiles of sheet materials and formed parts. The saw band can also be replaced with a file chain or a sand belt for filing or grinding. It is a common part processing tool.

[0003] At present, the existing sawing machines usually use tools such as conveying rollers or conveyor belts to load or unload parts. After the conveying rollers or conveyor belts transport the parts to the clamping assembly position, the clamping assembly clamps the parts, and the saw band cuts the parts. Then, the conveying rollers or conveyor belts are used to move the cut-off material heads away from the sawing machine. However, although the conveying rollers or conveyor belts can drive the material heads away from the sawing machine, they cannot transport the material heads to the discharge rack. Still, workers need to manually carry the material heads on the conveying rollers or conveyor belts to the discharge rack. Some parts are not only heavy, but the positions just cut by the saw band are relatively hot, which is somewhat dangerous, and manual handling is inefficient and has low practicability. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an automatic blanking mechanism for a sawing machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automatic blanking mechanism for a sawing machine includes a blanking table and a first electric slide rail. A transfer groove is opened on the upper surface of the blanking table, and a plurality of conveying rollers are rotatably connected to the inner wall of the transfer groove. The material heads after being processed by the sawing machine move to the right through the conveying rollers. A support plate is fixedly connected to the back of the blanking table, and a guiding component is fixedly connected to the upper surface of the support plate. An activity support plate is slidably connected to the inner wall of the first electric slide rail, and a transfer component is fixedly connected to the upper surface of the activity support plate. The guiding component includes a second electric slide rail, an activity block is slidably connected to the inner wall of the second electric slide rail, and a strip-shaped frame is fixedly connected to the lower surface of the activity block. Two connecting plates are slidably connected to the inner top wall of the strip-shaped frame, and guiding plates are fixedly connected to the lower surfaces of the two connecting plates. The guiding plates can guide the material heads on the conveying rollers to avoid the situation that the material heads shift outward and fall off, and the second electric slide rail can drive the guiding plates to move left and right through the activity block, with higher flexibility;

[0007] The transfer component includes a storage box. Four partition plates are fixedly connected to the inner bottom wall of the storage box. The four partition plates divide the storage box into five storage areas. The material heads guided by the guide plate can enter different storage areas. A driving motor is fixedly connected to the upper surface of the storage box. The output end of the driving motor is fixedly connected to a screw rod. A pressing plate is slidably connected to the inner wall of the storage box. The driving motor can drive the pressing plate to descend through the screw rod, so as to press the material heads entering the storage area and prevent the material heads from shaking and falling. An electric telescopic rod is fixedly connected to the right side of the storage box. A strip-shaped plate is slidably connected to the inner wall of the storage box. Five circular ejector rods are fixedly connected to the left side of the strip-shaped plate. When the first electric slide rail drives the storage box to move to the position of the blanking rack through the movable support plate, the electric telescopic rod can eject all the material heads in the storage area through the strip-shaped plate and the circular ejector rods, thus realizing automatic blanking operation.

[0008] Preferably, the length of the first electric slide rail is greater than the width of the blanking table, and the height of the guide plate is greater than the height of the conveying roller. The guide plate can move left and right on the conveying roller and does not affect the normal operation of the conveying roller.

[0009] Preferably, the bottom end of the screw rod extends into the interior of the storage box and is rotatably connected to the inner bottom wall of the storage box.

[0010] Preferably, a threaded hole is formed in the upper surface of the pressing plate. The pressing plate is threadedly connected to the screw rod through the threaded hole. The driving motor can drive the pressing plate to move up and down through the screw rod. The positions of the five circular ejector rods correspond to the positions of the five storage areas respectively. The output end of the electric telescopic rod is fixedly connected to the right side of the strip-shaped plate. The electric telescopic rod can drive the five circular ejector rods to move to the left through the strip-shaped plate.

[0011] Preferably, a bidirectional lead screw is rotatably connected to the front surface of the strip-shaped frame, and the rear end of the bidirectional lead screw is rotatably connected to the inner wall of the strip-shaped frame.

[0012] Preferably, threaded holes are formed in the front surfaces of the two connecting plates. The two connecting plates are threadedly connected to the positive and negative threads on the surface of the bidirectional lead screw through the threaded holes respectively. Rotating the bidirectional lead screw can adjust the distance between the two guide plates through the connecting plates, which is convenient for guiding material heads of different sizes.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The waste material after being processed by the sawing machine falls on the conveying rollers and is guided by the guide plate at the same time, and then moves to the storage area in the storage box. The second electric slide rail drives the guide plate to move back and forth through the movable block and the strip-shaped frame, so that the waste material can be conveyed to different storage areas. At the same time, the driving motor drives the pressing plate to descend through the screw rod to press the waste material tightly. After the storage box is full, the first electric slide rail drives the waste material to move to the discharging rack position through the movable supporting plate. The electric telescopic rod can squeeze the waste material through the strip-shaped plate and the circular ejector rod to make it move onto the discharging rack, eliminating the need for manual handling of the waste material by workers and providing higher safety;

[0015] 2. Rotate the bidirectional lead screw, and the distance between the two guide plates can be adjusted through the two connecting plates, so that the two guide plates can be suitable for waste materials of different sizes and guide waste materials of different sizes, with high flexibility.

The length of the first electric slide rail 2 is greater than the width of the blanking table 1. After being processed by the sawing machine, the metal workpiece falls on the blanking table 1 and is driven by the conveyor rollers 3 to move to the right. A support plate 4 is fixedly connected to the back surface of the blanking table 1. A guiding component is fixedly connected to the upper surface of the support plate 4. An active support plate 5 is slidably connected to the inner wall of the first electric slide rail 2. A transfer component is fixedly connected to the upper surface of the active support plate 5. The guiding component includes a second electric slide rail 6. An active block 7 is slidably connected to the inner wall of the second electric slide rail 6. And a strip-shaped frame 8 is fixedly connected to the lower surface of the active block 7. Two connecting plates 9 are slidably connected to the inner top wall of the strip-shaped frame 8. Guiding plates 10 are fixedly connected to the lower surfaces of the two connecting plates 9. The height of the guiding plate 10 is greater than the height of the conveyor roller 3. When the material head passes through the position of the guiding plate 10, under the blocking and guiding action of the guiding plate 10, it starts to move in a fixed direction;

[0022] The transfer component includes a storage frame 11. Four partition plates 12 are fixedly connected to the inner bottom wall of the storage frame 11. The four partition plates 12 divide the storage frame 11 into five storage areas 13. After being affected by the guiding plate 10, the material head moves into the storage area 13. At the same time, the second electric slide rail 6 can drive the guiding component to move back and forth through the active block 7, so that each material head can be transferred to each storage area 13. A driving motor 14 is fixedly connected to the upper surface of the storage frame 11. A screw rod 15 is fixedly connected to the output end of the driving motor 14. The bottom end of the screw rod 15 extends into the interior of the storage frame 11 and is rotatably connected to the inner bottom wall of the storage frame 11. A pressing plate 16 is slidably connected to the inner wall of the storage frame 11. A threaded hole is opened on the upper surface of the pressing plate 16. The pressing plate 16 is threadedly connected to the screw rod 15 through the threaded hole. After the material head is transferred to the storage area 13, the driving motor 14 drives the pressing plate 16 to descend through the screw rod 15, thereby pressing the material head tightly in the storage area 13. An electric telescopic rod 17 is fixedly connected to the right side of the storage frame 11. A strip-shaped plate 18 is slidably connected to the inner wall of the storage frame 11. The output end of the electric telescopic rod 17 is fixedly connected to the right side of the strip-shaped plate 18. Five circular ejector rods 19 are fixedly connected to the left side of the strip-shaped plate 18. The positions of the five circular ejector rods 19 correspond to the positions of the five storage areas 13 respectively. After the storage area 13 is filled with material heads, the first electric slide rail 2 drives the storage frame 11 to move to the position of the discharging rack through the active support plate 5. At the same time, the electric telescopic rod 17 is started, and the circular ejector rods 19 are driven by the strip-shaped plate 18 to squeeze the material heads so that they move onto the discharging rack, with a higher degree of automation and no need for manual handling by workers.

[0023] Embodiment 2: A bidirectional lead screw 20 is rotatably connected to the front surface of the strip-shaped frame 8, and the rear end of the bidirectional lead screw 20 is rotatably connected to the inner wall of the strip-shaped frame 8. Thread holes are formed in the front surfaces of the two connecting plates 9, and the two connecting plates 9 are respectively threadedly connected to the positive and negative threads on the surface of the bidirectional lead screw 20 through the thread holes. When the material head is too large and the guide plate cannot guide it, the bidirectional lead screw 20 is rotated to drive the two connecting plates 9 to move towards the opposite sides, thereby increasing the distance between the two guide plates 10, facilitating the guiding process for material heads of different sizes, and having higher flexibility.

[0024] Working principle: First, the metal material head after being processed by the sawing machine falls on the blanking table 1, is driven by the conveyor roller 3, and moves to the right. When it moves to the position of the guide plate 10, it is blocked by the guide plate 10, and the material head starts to move in a fixed direction and is transferred to the storage area 13 in the storage frame 11 through the conveyor roller 3. At the same time, the second electric slide rail 6 drives the guide plate 10 to move back and forth above the conveyor roller 3 through the movable block 7, the strip-shaped frame 8, and the connecting plate 9, so that each material head can be transferred to different storage areas 13. When the storage area 13 is full, the driving motor 14 drives the pressing plate 16 to descend through the screw rod 15, thereby pressing the material heads in the storage area 13. At this time, the first electric slide rail 2 drives the storage frame 11 to move to the discharging rack position through the movable supporting plate 5, and the electric telescopic rod 17 drives the circular ejector rod 19 through the strip-shaped plate 18 to push all the material heads in each storage area 13 onto the discharging rack, and then returns to the position of the blanking table 1 to complete the blanking operation again. At the same time, when guiding the blanking of material heads of different sizes, the bidirectional lead screw 20 is rotated to drive the two connecting plates 9 to move towards the opposite sides or the opposite sides, thereby increasing or decreasing the distance between the two guide plates 10, facilitating the guiding process for material heads of different sizes, having higher flexibility, and eliminating the need for manual handling of the material heads by workers, which not only improves the stability but also ensures the blanking efficiency and has higher practicality.
