Description

Technical Field

[0001] This invention belongs to the field of magnetic tile mold technology, and particularly relates to a chamfering device and method for the R-angle of magnetic tile molds. Background Technology

[0002] A magnetic tile mold is a tool used to shape permanent magnet materials (such as neodymium iron boron and ferrite). For example... Figure 1 , Figure 2 The magnetic tile mold shown includes a main plate 1 and several protrusions 2 disposed on the main plate 1. In order to enhance the strength and safety of the mold itself, as well as its adaptability in production, the existing technology requires chamfering of the four corners of the main plate 1.

[0003] Many existing chamfering devices are only suitable for molds of fixed sizes. However, changes in market demand often require manufacturers to respond quickly and adjust production lines flexibly. For example, in the production of magnetic tile products, various sizes of magnetic tile molds may be used. If the chamfering device cannot be adjusted, then the device can only be used for a certain fixed size of product, which greatly limits its application range and reduces the flexibility and versatility of the equipment.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Example

[0035] like Figure 3 , Figure 4 , Figure 5 As shown, Figure 3 The diagram shown is a schematic representation of the overall structure of the chamfering device in the embodiment. Figure 4 The diagram shown is a top view of the positional relationship between the annular track and the magnetic tile mold in the embodiment. Figure 5 What is shown is Figure 3 Enlarged schematic diagram of the structure at point A in the middle;

[0036] This device includes:

[0037] Workbench 11 and support 12;

[0038] The cutting assembly includes multiple sets of concentric annular tracks with different diameters. Each set of annular tracks is respectively arranged opposite to each other on the worktable 11 and the support 12, and the positions are corresponding. Each set of annular tracks is provided with a slider 24, which slides with the annular track. Opposite sliders 24 are connected by a connecting rod 25, and a milling cutter 26 is rotatably mounted on the connecting rod 25.

[0039] The cutting assembly also includes a mounting block 28, which is rotatably mounted on the bracket 12. A telescopic rod 27 is hinged to one side of the mounting block 28, and the other end of the telescopic rod 27 is hinged to a slider 24 on the same side. A groove 241 is provided on the slider 24 near the connecting rod 25, and a spring 29 is provided in the groove 241. The slider 24 can slide at the end of the connecting rod 25, and the slider 24 has at least a first state and a second state.

[0040] First state: Spring 29 is in its natural state, slider 24 is movably embedded in the same set of annular tracks, and mounting block 28 rotates to drive telescopic rod 27, causing slider 24 to slide along the annular track;

[0041] Second state: Apply external force to slider 24 to compress spring 29, so that sliders 24 in the same set of circular tracks can all disengage from the circular track.

[0042] It also includes a fixing component, which is correspondingly set at the center of the annular track group. The magnetic tile mold is installed on the fixing component, and the milling cutter 26 cuts the four corners of the main body plate 1 when it moves along the annular track.

[0043] Specifically, the support 12 and the worktable 11 are arranged opposite each other on the upper and lower sides. Two annular tracks of the same diameter are arranged opposite each other on the support 12 and the worktable 11 as a group. The milling cutter 26 moves in any group of annular tracks through the connecting rod 25 and the slider 24 to cut the four corners of the magnetic tile mold body plate 1 located in the middle, thereby forming rounded corners.

[0044] The fixed component can position and fix magnetic tile molds of different sizes. Through multiple sets of concentric but different diameter annular tracks set on the outside of the fixed component, and through the set spring 29, groove 241 and telescopic rod 27, the position of the slider 24 can be adjusted, thereby switching the milling cutter 26 to different annular track sets to realize the chamfering operation of magnetic tile molds of different sizes.

[0045] Specifically, the circular track group includes circular track 1 21, circular track 2 22 and circular track 3 23, wherein the diameters of circular track 1 21, circular track 2 22 and circular track 3 23 increase sequentially;

[0046] When switching the circular track group, the two sliders are pressed towards each other, the spring 29 is compressed, and the slider 24 can be separated from the original track group. Then the slider 24 is transferred and embedded into another circular track group. The telescopic rod 27 will extend and retract accordingly. After the slider 24 is transferred and embedded into another circular track group, the external force is removed, the spring 29 returns to its original position, and thus resists the slider 24, so that the slider 24 is stably embedded into the replaced circular track group. Finally, the rotation of the mounting block 28 can drive the telescopic rod 27 to drive the slider 24 to slide along the circular track.

[0047] The spring 29 is selected according to the actual application environment. For example, the upper spring 29 should be able to overcome the gravity of the slider 24 at this end, resist the slider 24, and enable the slider 24 to move stably and be embedded in the ring track.

[0048] Figure 3 , Figure 6 , Figure 7 , Figure 8 As shown, Figure 3 The diagram shown is a schematic representation of the overall structure of the chamfering device in the embodiment. Figure 6 The diagram shown is a front view of the fixed component in the embodiment; Figure 7 The diagram shown is a top view of the fixing component in the embodiment; Figure 8 The diagram shown illustrates the cooperation relationship between the guide post and the clamping seat in the embodiment.

[0049] The fixing component includes a fixing seat 30 and clamping seats 32 movably disposed on both sides of the fixing seat 30. The fixing seat 30 and the clamping seats 32 form a receiving groove for placing the protrusion 2 of the magnetic tile mold. The main body plate 1 of the magnetic tile mold is placed on the top of the clamping seat 32, and the clamping seats 32 are close to each other to clamp the protrusion 2.

[0050] The structure of the fixing component is adapted to the structure of the magnetic tile mold. When the magnetic tile mold is installed, its protrusion 2 is placed downwards, the main body plate 1 is located above, and the clamping seats 32 extend from all four sides of the main body plate 1. The clamping seats 32 can clamp the outermost protrusion 2 of the magnetic tile mold. The adjustable clamping seats 32 are suitable for magnetic tile molds of different sizes and specifications.

[0051] Electric push rods 33 are provided at the ends of the fixed base 30 near the clamping seats 32 on both sides. The output end of the electric push rod 33 is connected to the clamping seat 32 on the corresponding side. The electric push rod 33 drives the clamping seat 32 to move closer to the fixed base 30 or move away from the fixed base 30 simultaneously.

[0052] The electric push rod 33 drives the two clamping seats 32 to move closer or further apart, so as to realize the clamping action and the release action.

[0053] Several guide posts 34 are also provided at intervals on the fixed base 30 near the ends of the clamping bases 32 on both sides. The clamping base 32 is provided with a guide groove 321 for the guide posts 34 to be movably inserted. The guide posts 34 and the guide groove 321 are slidably engaged.

[0054] By using the guide post 34 and guide groove 321, the stability of the clamping seat 32 during the adjustment process is increased, and the clamping seat 32 will not detach from the fixed seat 30 within the adjustment range of the electric push rod 33.

[0055] like Figure 3 As shown, Figure 3 The diagram shown is a schematic representation of the overall structure of the chamfering device in the embodiment.

[0056] A motor 41 is installed on the top of the bracket 12. The output end of the motor 41 passes through the bracket 12 and is connected to the mounting block 28. The motor 41 drives the mounting block 28 to rotate.

[0057] Motor 41 drives the mounting block 28 to rotate.

[0058] A fixed frame 42 is provided on the connecting rod 25. The milling cutter 26 is rotatably mounted on the fixed frame 42. A second motor 43 is also provided on the fixed frame 42. The output end of the second motor 43 is connected to the milling cutter 26, and the second motor 43 drives the milling cutter 26 to rotate.

[0059] The fixed frame 42 is used to install the milling cutter 26, and the motor 43 drives the milling cutter 26 to rotate. The milling cutter 26 can be selected as needed according to specific requirements.

[0060] Working principle: This device can fix and chamfer magnetic tile molds of different specifications. By switching annular track groups of different diameters, the position and movement path of the milling cutter 26 can be changed. When switching annular track groups, the two sliders are pressed towards each other, the spring 29 is compressed, and the slider 24 can be separated from the original track group. Then the slider 24 is transferred and embedded into another annular track group. The telescopic rod 27 will extend and retract accordingly. After the slider 24 is transferred and embedded into another annular track group, the external force is removed, the spring 29 returns to its original position, and thus resists the slider 24, so that the slider 24 is stably embedded into the changed annular track group. Finally, the rotation of the mounting block 28 can drive the telescopic rod 27 to move the slider 24 along the annular track to achieve the chamfering of the four corners of the magnetic tile mold.
