Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machines, in particular to a revolving door structure of a wire cutting machine. Background Art

[0002] Diamond wire cutting machines are becoming more and more popular in the cutting of hard and brittle materials such as monocrystalline silicon and polycrystalline silicon. The outside of the cutting machine is generally provided with an openable protective cover or protective door. After the workpiece is placed, the protective door is closed to prevent workers from touching it and causing danger. For example, a multi-wire cutting device disclosed in the utility model patent with authorization announcement number CN219445672U has a hinged replacement door on one side of the device housing. During the cutting process of the workpiece, the diamond ring wire and the workpiece generate a lot of heat due to friction, and generally need to be sprayed with coolant. If a hinged protective door is used, when the protective door needs to be opened after a period of processing, since there is coolant on the inside of the protective door (the coolant will splash on the inside of the door during the cutting process), opening it outward will cause part of the coolant to flow to the ground outside the equipment, making the ground slippery. There are also some equipment that use removable protective doors. After the cutting is completed, the protective door is directly removed and then placed on the ground. This not only has the problem of bringing part of the coolant to the ground, but also has the problem of inconvenient operation. Utility Model Content

[0003] The utility model aims to provide a rotary door structure for a wire cutting machine, so as to solve the problem that the existing protective door structure may cause slippery ground and inconvenience in operation when the door is opened.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A revolving door structure for a wire cutting machine comprises a door body and a track. A pair of rollers are respectively provided at the upper and lower ends of the door body. The pair of rollers are respectively close to the two side edges of the door body. The rollers are rotatably assembled on the door body and the rotation axes of the two are along the up and down directions. There are two tracks, which are respectively located at the upper and lower sides of the door body. The tracks have track grooves for the rollers to slide therein. The track has a transverse section and a longitudinal section. The longitudinal section extends from the transverse section to the rear of the wire cutting machine, and the longitudinal section is connected to the transverse section by an arc transition.

[0006] Furthermore, when the door body is in a closed state, the rollers are both located in the transverse section of the track; when the door body is in an open state, one of the pair of rollers is located in the transverse section of the track, and the other is located in the longitudinal section of the track.

[0007] Further, the track groove of the upper track is a U-shaped groove with an opening facing downward, and the track groove of the lower track is a U-shaped groove with an opening facing upward.

[0008] Furthermore, the door body includes a rectangular frame and a glass panel embedded in the rectangular frame.

[0009] Furthermore, a push-pull hand groove is provided on the rectangular frame.

[0010] Furthermore, the door bodies are provided with two, and when opening, one door body moves to the left rear, and the other door body moves to the right rear.

[0011] Furthermore, a shielding strip is provided on the rear side of one of the door bodies, and when both door bodies are closed, the shielding strip is located behind the joint between the two door bodies.

[0012] Beneficial effects of the utility model:

[0013] The protective door body of the utility model is a revolving door that opens inwards. When the door body is opened, the door body moves to the left rear and / or to the right rear (or for one door body, and for two door bodies). When the door body is in a closed state, the rollers at the upper and lower ends are both located in the transverse section of the track. When the door body is in an open state, one of a pair of rollers is located in the transverse section of the track, and the other is located in the longitudinal section of the track, so that the door body is rotated inwards to open. After the door body is opened, since the door body opens inwards, the coolant attached to the inner side of the door body will not fall to the ground outside, but fall into the sump inside the wire cutting machine, thereby solving the problem of coolant dripping on the ground caused by opening outwards or directly removing the door body, and the operation of opening and closing the door body is also very convenient. Moreover, the door body opens inward and does not occupy the external space of the wire cutting machine, which is convenient for peripheral operations. After opening in place, the door body is against the side of the wire cutting machine, and does not affect the internal operations such as picking up and placing workpieces and replacing diamond wires.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0021] Embodiments of the present utility model:

[0022] like Figure 1-Figure 5 As shown, a revolving door structure of a wire cutting machine includes a door body 1 and a track 4. A pair of rollers 2 are respectively provided at the upper and lower ends of the door body 1. The pair of rollers 2 are respectively close to the two side edges of the door body 1. The rollers 2 are rotatably assembled on the door body 1 and the rotation axes of the two are along the up and down directions, and can rotate flexibly.

[0023] There are two tracks 4, which are located on the upper and lower sides of the door body 1. In this embodiment, the door body 1 is provided with two tracks 4, which are U-shaped as a whole. The track 4 is fixed in the housing 5 of the wire cutting machine and is located in the cutting chamber on the front side. The cutting chamber is equipped with a working slide and a cutting mechanism (including a wire wheel and a diamond wire) for supporting the workpiece. This part of the structure is not an improvement of the utility model and is not shown. The track 4 has a track groove 44. The track groove of the upper track is a U-shaped groove with an opening facing downward, and the track groove 44 of the lower track 4 is a U-shaped groove with an opening facing upward. The track groove 44 allows the roller 2 to slide therein and prevents the roller 2 from falling out.

[0024] The track 4 has a transverse section 41 and a longitudinal section 42. The transverse section 41 is relatively long. When the door body 1 is closed, both door bodies 1 are located on the transverse section 41. The longitudinal section 42 extends from the transverse section 41 toward the rear of the wire cutting machine. The longitudinal section 42 and the transverse section 41 are connected by an arc transition, which is defined as an arc transition section 43. The arc transition section 43 is provided to facilitate the roller 2 to move from the transverse section 41 to the longitudinal section 42 without getting stuck.

[0025] When the door body 1 is in a closed state, the rollers 2 are all located in the transverse section 41 of the track. When the door body 1 is opened, one door body 1 moves to the left rear, and the other door body 1 moves to the right rear. When the door body 1 is in an open state, one of the pair of rollers 2 is located in the transverse section 41 of the track, and the other is located in the longitudinal section 42 of the track. The position of the roller 2 in the longitudinal section 42 determines the opening range of the door body 1. When the door body 1 is opened more, the roller 2 is located at a position closer to the inside of the longitudinal section 42, which is manually controllable. After the door body 1 is fully opened, since the door body 1 is opened inward, the coolant attached to the inside of the door body 1 will not fall to the ground outside, but fall into the sump inside the wire cutting machine, thereby solving the problem of coolant dripping on the ground caused by opening outward or directly removing the door body 1, and the door body 1 is opened inward, and does not occupy the external space of the wire cutting machine; after opening to the full extent, it is close to the side of the wire cutting machine, and does not affect the operations of picking up and placing workpieces, replacing diamond wires, etc.

[0026] The door body 1 includes a rectangular frame and a glass panel embedded in the rectangular frame. The transparent glass panel is used so that the working condition of the wire cutting machine can be observed. Of course, acrylic panels or metal sheets can also be used in other embodiments. A push-pull hand groove 3 is provided on the rectangular frame, so that when operating the door body 1, the worker's fingers can be inserted into the push-pull hand groove 3 to apply force to push or pull the door to open or close the door accordingly. The two door bodies 1 can be opened and closed independently.

[0027] When both door bodies 1 are in a closed state, in order to prevent the coolant from splashing outward from the joint between the two door bodies 1, a shielding strip is provided on the rear side of one of the door bodies 1, such as Figure 4 As shown, the length direction of the shielding strip is arranged along the up-down direction. A part of the shielding strip is fixed on one of the door bodies 1, and a part of the shielding strip is exposed, and the exposed part forms a shielding portion. When both door bodies 1 are closed, the shielding strip is located behind the joint of the two door bodies 1, and the shielding portion of the shielding strip is just located at the rear side of the other door body 1, thereby blocking the gap between the two door bodies 1.

[0028] In order to control the final position of the two door bodies 1 when they are closed, a limit convex point can be set at the center of the transverse track to prevent the door bodies 1 from crossing the limit convex point. When one of the door bodies 1 is closed, it moves to the position of the limit convex point, that is, it is just closed in place.

[0029] In this embodiment, two door bodies are provided. In other embodiments, one door body may be provided. In this case, if the track is still the U-shaped track in the above embodiment, the door can be opened by pushing to the left rear or pushing to the right rear. In this case, the transverse section of the U-shaped track should be shortened. When a door body is selected, the track may be set to be L-shaped, that is, the door can be opened by pushing to the left rear or pushing to the right rear.
