Description

Technical Field

[0001] This utility model relates to the field of metal die casting processing technology, and specifically to a cutting device for metal die casting processing. Background Technology

[0002] Trimming of die-cast parts refers to a process in metal die casting that removes excess material (such as flash, overflow, etc.) from the surface of the casting. This excess material typically overflows from the mold edges when the mold closes due to the fluidity of the molten metal, resulting in unwanted protrusions on the casting surface. These protrusions need to be removed through trimming to achieve the final precision and appearance requirements.

[0003] In the metal die casting trimming device disclosed in announcement number CN217044827U, the first clamping plate, the second clamping plate, and the trimming die held between the two clamping plates move downwards simultaneously, so that the trimming die contacts the casting after moving downwards, and trims the casting.

[0004] However, the edge-cutting device for this metal die-casting has the following disadvantages: when cutting the edge of a die-casting, it is necessary to wait for one die-casting to be cut and removed, then place a new die-casting and cut the edge again, which involves a lot of waiting time and affects the overall processing efficiency. In addition, cutting the edge of the die-casting generates a lot of waste, which is inconvenient for personnel to clean up and collect. Utility Model Content

[0005] The technical problem to be solved by this utility model is as follows: When cutting the edge of a die casting, it is necessary to wait for the edge of one die casting to be cut and then remove it, then place a new die casting and cut the edge again. There is a lot of waiting time, which affects the overall processing efficiency. In addition, the edge cutting of die casting will generate a lot of waste material, which is inconvenient for personnel to clean and collect.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A trimming device for processing metal die-casting parts includes a trimming table, a limiting rail fixedly installed in the middle of the trimming table, a switching mechanism fixedly installed on one side of the limiting rail, a switching table threadedly connected to the surface of the switching mechanism, a support frame fixedly installed in the middle of the top surface of the trimming table, a trimming mechanism fixedly installed on the top surface of the support frame, a collection box fixedly installed on the bottom surface of the trimming table, a B servo motor fixedly installed on the outer surface of the collection box, and a crushing mechanism fixedly installed at the output end of the B servo motor.

[0008] As a further embodiment of this utility model: the switching mechanism includes an A servo motor and a threaded screw. The A servo motor is fixedly installed on one side of the limiting track, and the threaded screw is fixedly installed at the output end of the A servo motor. The A servo motor is used to drive the threaded screw to rotate.

[0009] As a further embodiment of this utility model: the trimming mechanism includes a hydraulic cylinder and an upper trimming die. The hydraulic cylinder is fixedly installed on the top surface of the support frame, and the upper trimming die is fixedly installed at the output end of the hydraulic cylinder. The trimming mechanism is used to trim the edges of metal die castings.

[0010] As a further embodiment of this utility model: the crushing mechanism includes gear A, gear B and crushing rollers. Gear A is fixedly mounted on the output end of servo motor B. One side of gear B meshes with gear A. There are two sets of crushing rollers, which are fixedly mounted on one side of gear A and gear B respectively. Gear A and gear B are both rotatably mounted on the outer surface of the collection box. The crushing mechanism is used to crush and collect the switched metal materials.

[0011] As a further embodiment of this utility model: a door is hinged to one side of the collection box, and a handle is fixedly installed on the surface of the door for opening and closing the door.

[0012] As a further embodiment of this utility model: the switching platform is slidably disposed inside the limiting track, and three sets of lower molds are fixedly disposed on the top surface of the switching platform along the axial direction. The lower molds are adapted to the upper cutting molds, and the lower molds are used to prevent metal die castings.

[0013] As a further embodiment of this utility model: a motor mount is fixedly installed on the bottom of the B servo motor, and one side of the motor mount is fixedly connected to the collection box, which facilitates the installation of the B servo motor.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting the switching mechanism and the trimming mechanism, the metal die casting is placed on the lower mold. The hydraulic cylinder is opened, which drives the upper trimming mold to press down and cut off the edge scrap of the metal die casting. After the trimming of one metal die casting is completed, the A servo motor drives the threaded screw to rotate, so that the next metal die casting is transported to the lower part of the upper trimming mold for trimming. During the trimming process, the operator can place or remove the metal die casting on the lower mold, which reduces waiting time and improves work efficiency.

[0016] 2. With the crushing mechanism in place, personnel clean the metal scrap generated from the cutting edge into the collection box. The B servo motor drives the A gear to rotate, which in turn drives the B gear to rotate, causing the two sets of crushing rollers to rotate and crush the metal scrap to reduce space occupation. On the one hand, this increases the capacity of the collection box, and on the other hand, the crushed metal scrap is easier to recycle and reuse. Attached Figure Description

On the one hand, it increases the capacity of the collection box 7, and on the other hand, the crushed metal waste is also easy to recycle and reuse.

[0027] like Figure 2 As shown, the switching mechanism 3 includes an A servo motor 301 and a threaded screw 302. The A servo motor 301 is fixedly installed on one side of the limit rail 2, and the threaded screw 302 is fixedly installed at the output end of the A servo motor 301.

After the trimming of one metal die casting is completed, the A servo motor 301 drives the threaded screw 302 to rotate, so that the next metal die casting is transported to the lower part of the upper trimming mold 602 for trimming. During the trimming process, the personnel can place or remove the metal die casting on the lower mold 11, which reduces the waiting time and improves the work efficiency.

[0040] Personnel clean the metal scrap generated from the cutting edge into the collection box 7. The B servo motor 8 drives the A gear 901 to rotate, which in turn drives the B gear 902 to rotate, causing the two sets of crushing rollers 903 to rotate as well, crushing the metal scrap and reducing the space occupied. On the one hand, this increases the capacity of the collection box 7, and on the other hand, the crushed metal scrap is easier to recycle and reuse.
