Description

Technical Field

[0001] This utility model relates to the field of precision machining, and in particular to an automatic sprue cutting device. Background Technology

[0002] Nowadays, with the development of industrial technology, when dealing with many complex structures and shapes of workpieces, we no longer rely on traditional turning and engraving processes. Instead, we use a more convenient casting process. After casting, the product is connected to the casting mold by the casting gate. After casting, the casting gate is cut off by a high-speed rotating cutting blade, and the product is cut off from the casting mold, thus completing the processing.

[0003] However, when cutting the sprue in casting, since multiple workpieces are usually cast simultaneously during the entire casting process, there will be workpieces at multiple angles and directions. When cutting, the entire workpiece first needs to be positioned so that it is in a preset position and then fixed. After completing the cutting on one side, the workpiece needs to be released and then flipped over for cutting on the back side. This results in more steps in the entire operation, which in turn reduces the overall efficiency of sprue cutting. Therefore, an automatic sprue cutting device is provided. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sprue cutting device to solve the problem mentioned in the background art, which is that the entire operation process involves more steps, thereby reducing the overall sprue cutting efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic sprue cutting device, comprising a cutting table and a cutting unit mounted on the cutting table. A workpiece clamping and adjusting unit is provided on the cutting table. A two-dimensional traveling unit for driving the workpiece clamping and adjusting unit to move horizontally is provided between the workpiece clamping and adjusting unit and the cutting table.

A clamping cylinder for adjusting the distance between the fixed support part and the movable support part is installed on the movable support part. Both the fixed support part and the movable support part are provided with clamping parts. A rotary servo for driving the clamping parts to rotate is installed on the movable support part, so that the workpiece is clamped in the clamping parts and moves and rotates horizontally, thereby enabling the workpiece to contact the cutting unit at a preset distance and angle for cutting.

[0006] Preferably, the two-dimensional walking unit includes an X-axis slide rail fixedly mounted on the cutting table and a Y-axis slide rail slidably mounted on the X-axis slide rail. A carrier plate is slidably mounted on the Y-axis slide rail. The fixed support part is fixedly mounted on the carrier plate, and the movable support part is slidably mounted on the carrier plate.

[0008] Preferably, a Y-axis motor is fixedly installed on the Y-axis slide rail, and a second lead screw is fixedly provided at the output end of the Y-axis motor. The carrier plate is threadedly connected to the second lead screw, so that the carrier plate reciprocates perpendicular to the arrangement direction of the X-axis slide rail.

[0009] Preferably, a guide hopper is fixedly provided at the end of the carrier plate, and a discharge groove is provided on the cutting table. The outer end of the guide hopper is inclined downward and faces the discharge groove so that the cutting material can slide down along the guide hopper and enter the discharge groove.

[0014] Preferably, the end of the cutting carrier is movably hinged with a traction unit, the bottom end of which is mounted on the cutting table. The traction unit pulls the end of the cutting carrier up and down to bring the cutting head closer to or away from the workpiece.

[0015] The technical effects and advantages of this utility model are as follows: By inserting one end of the workpiece die head into the first rotating chuck and the other end into the second rotating chuck, and then activating the clamping cylinder, the movable support moves closer to the fixed support, thereby clamping the workpiece die head using the slot between the first and second rotating chucks. Then, the second rotating chuck is driven to rotate by a rotary servo, causing the workpiece to rotate to a preset angle.

[0020] The two-dimensional walking unit 4 includes an X-axis slide rail 41 fixedly mounted on the cutting table 1 and a Y-axis slide rail 42 slidably mounted on the X-axis slide rail 41. A carrier plate 44 is slidably mounted on the Y-axis slide rail 42. A fixed support part 31 is fixedly mounted on the carrier plate 44, and a movable support part 32 is slidably mounted on the carrier plate 44. An X-axis motor 43 is fixedly mounted on the X-axis slide rail 41. A first lead screw is fixedly mounted on the output end of the X-axis motor 43, and the Y-axis slide rail 42 is threadedly connected to the first lead screw, so that the Y-axis slide rail 42 can reciprocate along the arrangement direction of the X-axis slide rail 41. A Y-axis motor 45 is fixedly mounted on the Y-axis slide rail 42. A second lead screw is fixedly mounted on the output end of the Y-axis motor 45, and the carrier plate 44 is threadedly connected to the second lead screw, so that the carrier plate 44 reciprocates perpendicular to the arrangement direction of the X-axis slide rail 41, thereby driving the entire carrier plate 44 to move freely in the X-axis and Y-axis directions in the horizontal plane.

[0021] A guide hopper 13 is fixedly provided at the end of the carrier plate 44, and a discharge groove 12 is provided on the cutting table 1. The outer end of the guide hopper 13 is inclined downward and faces the discharge groove 12 so that the cutting material can slide down along the guide hopper 13 and enter the discharge groove 12.

[0022] The clamping part includes a first rotating bracket 34 rotatably disposed in the fixed support part 31 and a second rotating bracket 35 rotatably disposed in the movable support part 32. The rotation servo 36 is connected to the second rotating bracket 35 for transmission.

[0023] The first rotary chuck 34 and the second rotary chuck 35 are respectively provided with slots 37 for restricting the workpiece on opposite sides. The clamping cylinder 33 is fixedly installed on the carrier plate 44, and the output end of the clamping cylinder 33 is fixedly connected to the movable support part 32. One end of the workpiece die head is inserted into the first rotary chuck 34, and then the other end is inserted into the second rotary chuck 35. Then the clamping cylinder 33 is activated, so that the movable support part 32 moves closer to the fixed support part 31, thereby using the slots 37 between the first rotary chuck 34 and the second rotary chuck 35 to clamp the workpiece die head.

[0024] The cutting unit 2 includes a bracket 21 fixedly installed on one side of the discharge trough 12. A cutting carrier 22 is movably mounted on the bracket 21. A cutting head 24 is rotatably mounted at the end of the cutting carrier 22. A cutting motor 23 is fixedly mounted on the top of the cutting carrier 22.

The traction unit 25 pulls the end of the cutting carrier 22 up and down to make the cutting head 24 approach or move away from the workpiece. The traction unit 25 is driven by a motor to rotate the lead screw. The motor is mounted on the cutting table 1. The outer surface of the top of the lead screw is threaded with a connecting sleeve. The connecting sleeve is movably hinged to the cutting carrier 22. When the motor rotates in the forward and reverse directions, the connecting sleeve moves up and down along the drive lead screw, thereby pulling the cutting carrier 22 to flip back and forth.

[0026] Working principle: When using this device, one end of the workpiece die head is inserted into the first rotating bracket 34, and the other end is inserted into the second rotating bracket 35. Then, the clamping cylinder 33 is activated, causing the movable support part 32 to move closer to the fixed support part 31. The workpiece die head is clamped by the slot 37 between the first rotating bracket 34 and the second rotating bracket 35. Then, the second rotating bracket 35 is driven to rotate by the rotation servo 36, so that the workpiece is rotated to a preset angle. Then, the workpiece is driven to adjust its horizontal position by the X-axis motor 43 and the Y-axis motor 45, so that the entire sprue is facing the cutting head 24. At this time, the cutting motor 23 starts, driving the cutting head 24 to rotate, and then the traction unit 25 drives the entire cutting frame 22 to rotate, so that the height of the cutting head 24 drops to contact the sprue. At this time, the sprue is cut by the cutting head 24, and the cut part enters the discharge trough 12 through the guide hopper 13 to complete the discharge. After one side is cut, the entire workpiece is rotated 180 degrees by the rotary servo 36, and then the sprue cutting on the other side is performed. This allows for multi-sided sprue cutting with a single installation and positioning, making the operation more convenient, reducing the number of steps, and increasing efficiency.
