Description

Technical Field

[0001] The utility model relates to the technical field of trimming of pouring cups, and more specifically, to a trimming device for pouring cups. Background Art

[0002] Engraving grooves on the outer wall of the pouring cup is a way of trimming, but this way focuses more on the functional or structural transformation of the pouring cup rather than the traditional trimming. Such grooves are called pouring grooves or clamping grooves. During the casting process, especially in the case of multiple pourings or complex mold systems, precise positioning and fixation are crucial. The grooves can cooperate with the corresponding protruding parts of the gating system or other mold components to ensure the stability and accuracy of the pouring cup during the pouring process, so as to pour the liquid metal more precisely.

[0003] In the prior art, trimming the outer wall of the pouring cup is mostly carried out by manually engraving grooves. First, the pouring cup is fixed, then a ruler and a marking tool are used to accurately mark the position and size of the grooves on the outer wall of the pouring cup. Then, a cutting tool is held by hand and gently engraved along the marked lines. Since the grooves are generally not just a shallow layer, they need to be engraved multiple times to gradually deepen the grooves. Finally, a grindstone or sandpaper is used to polish the edges of the grooves to remove burrs and uneven parts. This processing method has the problems of high labor intensity of personnel and low processing efficiency. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a trimming device for pouring cups, which can drive the cutting tool to rotate by rotating the adjusting rod, so that the cutting tool contacts the pouring cup to be processed.

Enterprises can also choose a trimming device equipped with components such as an air extraction pump and a suction cup according to the procurement cost of the equipment to better fix the gate cup to be processed. A column 5 is fixedly connected to the upper end of the operating table 1. A pair of rotating grooves 501 and a clamp 502 are provided at the upper end of the column 5, and the clamp 502 is located directly above the rotating groove 501. A rotating ring 6 is rotatably connected in the rotating groove 501. An extension block 601 is fixedly connected to the upper end of the rotating ring 6. The notch position of the clamp 502 is a limit card slot 503. The extension block 601 is arranged in the limit card slot 503. A cutting tool 7 is fixedly connected to the outer end of the rotating ring 6. The cutting tool 7 is used to perform grooving treatment on the gate cup to be processed. An adjusting rod 8 is fixedly connected to the lower end of the cutting tool 7. It should be noted that the driving motor is not shown in the figure of this solution. Since the installation and opening / closing method of the driving motor and how to drive the electric control turntable 4 to rotate synchronously are all prior arts, they will not be elaborated here.

[0029] Please refer to Figures 2-4 , The rotating groove 501 is a reduced diameter part of the column 5. The inner diameter of the rotating ring 6 is greater than the outer diameter of the rotating groove 501 and less than the outer diameter of the column 5, so that the rotating ring 6 can rotate at the outer end of the rotating groove 501. A plurality of spherical grooves are provided on the inner surface of the rotating ring 6. Ball bearings 602 are installed in all the plurality of spherical grooves, effectively reducing the friction between the rotating ring 6 and the rotating groove 501 and facilitating personnel to rotate and adjust the rotating ring 6.

[0030] Please refer to Figure 2 and Figure 4 , The clamp 502 is a ring-shaped clamp with a notch. The extension block 601 is an arc-shaped block.

[0032] Working principle: When engraving and engaging grooves on the gating cup to be processed, first hold the adjusting rod 8 and rotate it to the right, so that the extension block 601 rotates to the right side of the limit card slot 503. Then place the gating cup on the electric control turntable 4. Next, start the driving motor. Then rotate the extension block 601 to the left through the adjusting rod 8, so that the cutting tool 7 contacts the surface of the gating cup to be processed and starts engraving the groove. The extension block 601 continues to deflect to the left, and the scale of the groove on the surface of the gating cup by the cutting tool 7 gradually deepens. When the extension block 601 rotates to the leftmost side of the limit card slot 503, the surface groove of the gating cup can be processed to the preset depth. Compared with the prior art, the utility model can effectively reduce the labor intensity of personnel while ensuring the engraving processing efficiency and processing quality of the gating cup.
