Description

Technical Field

[0001] This utility model relates to a device for removing flash from circular castings, belonging to the field of casting post-processing technology. Background Technology

[0002] Currently, using deburring devices to remove burrs (also known as flash or burrs) from round castings is a very common post-casting process. Examples include a stamping deburring device disclosed in CN218503091U and a deburring device disclosed in CN208913124U.

[0003] The technical solutions disclosed in the aforementioned patent documents still have the following technical problems, based on practical experience:

[0004] The above methods all utilize stamping (or punching, trimming) to remove flash. Stamping trimming uses the shearing force of a die to quickly remove the main, continuous flash material overflowing from the parting line or gating area of ​​the casting. This is the primary method for efficiently removing most flash. However, the stamping process is essentially a shearing process, inevitably leaving burrs and shearing marks. Additional grinding equipment is needed to treat these burrs and shearing marks. Since the casting needs to be transferred between different processes, the efficiency of post-casting processing is relatively low.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a device for removing flash from circular castings. It integrates stamping and grinding, allowing for continuous flash removal and rotary grinding at the same workstation, eliminating process changeover time and significantly improving the efficiency of post-casting processing.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A device for removing flash from circular castings includes a punch press body, with a lifting seat and a machine table arranged vertically at the front of the punch press body; a ring punch and an elastic telescopic rod are fixedly installed at the bottom of the lifting seat, the elastic telescopic rod passes vertically through the interior of the ring punch, and a pressure head is rotatably installed at the bottom end of the elastic telescopic rod; a horizontally arranged feeding trough is installed between the lifting seat and the machine table; one end of the feeding trough is located directly below the ring punch, and a circular discharge hole is opened near the end of the feeding trough, with a ring-shaped grinding blade fixedly installed at the bottom of the discharge hole, a turntable is arranged directly below the grinding blade, and an arc-shaped grinding head is installed on one side above the turntable.

[0009] Furthermore, the pressure head and the bottom end of the elastic telescopic rod are rotatably connected by a bearing, and the pressure head extends from the bottom end of the annular punch.

[0010] Furthermore, the elastic telescopic rod includes an inner rod and an outer rod that are slidably connected, and a compression spring is sleeved on the main body of the inner rod and the outer rod.

[0011] Furthermore, the pressure head adopts a contour-following structure, which adapts to the internal shape of the circular casting.

[0012] Furthermore, the bottom of the feeding trough is fixedly connected to the machine base via a support frame.

[0013] Furthermore, the main body of the feeding trough is connected to the inclined guide trough, and both the feeding trough and the guide trough have U-shaped cross-sections.

[0014] Furthermore, a horizontally positioned feeding cylinder is installed at the other end of the feeding trough.

[0015] Furthermore, the turntable is fixed to the top of the rotating shaft, and the bottom of the rotating shaft is connected to the output shaft of the motor via a coupling. The motor is fixed to the bottom of the machine base in a vertical direction.

[0016] Furthermore, the grinding head is mounted on the head of the piston rod of the feeding cylinder, and the cylinder body of the feeding cylinder is fixed to the support frame in a horizontal direction.

[0017] Furthermore, there is an inclined feeding trough below the turntable, and the cross-section of the feeding trough is U-shaped.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] In this invention, the annular punch and grinding blade work together to efficiently remove burrs from circular castings using press pressure. An elastic telescopic rod, in conjunction with a contouring pressure head, presses the ground circular casting onto a turntable. A bearing structure allows the casting to rotate freely, and a motor drives the turntable to rotate the casting. The grinding head then adheres to the outer edge for full-circumference precision grinding, eliminating burrs and shear marks. This invention integrates punching and burr removal with grinding, continuously completing both punching and grinding at the same station. This eliminates process changeover time and significantly improves the efficiency of post-casting processing. It solves the efficiency loss caused by multiple transfers and repositioning of castings in traditional processes, enabling fully automated assembly line operations.

[0027] The bottom of the lifting seat 3 is fixedly installed with an annular punch 4 and an elastic telescopic rod 5. The elastic telescopic rod 5 passes through the interior of the annular punch 4 in a vertical direction. A pressure head 6 is rotatably installed at the bottom end of the elastic telescopic rod 5. The pressure head 6 and the bottom end of the elastic telescopic rod 5 are rotatably connected by a bearing. The pressure head 6 extends out from the bottom end of the annular punch 4.

[0028] The elastic telescopic rod 5 includes an inner rod and an outer rod that are slidably connected, and a compression spring is sleeved on the main body of the inner rod and the outer rod.

[0029] The pressure head 6 adopts a contour-following structure, which is adapted to the internal shape of the circular casting. Under the action of the elastic telescopic rod 5, the pressure head 6 presses the ground circular casting onto the turntable 11 and rotates with the turntable 11.

[0030] A horizontally arranged feeding trough 7 is installed between the lifting seat 3 and the machine base 2. The bottom of the feeding trough 7 is fixedly connected to the machine base 2 through the support frame 16. The main body side of the feeding trough 7 is connected to the inclined guide trough. The top of the guide trough is connected to the vibrating feeding plate. The cross-section of the feeding trough 7 and the guide trough is U-shaped.
