Description

Technical Field

[0001] This application relates to the technical field of grinding, and more particularly to a grinding device for the edges of stamped parts. Background Technology

[0002] Stamping is a highly efficient material forming process widely used in the manufacture of metal structural parts. During the stamping and cutting process, burrs inevitably form on the edges of the stamped parts due to plastic deformation. These burrs not only affect the appearance quality of the product but may also cause scratches, stress concentrations, or assembly interference during subsequent assembly and use. Therefore, deburring is an indispensable step in the post-processing of stamped parts.

[0003] Currently, the deburring of sheet metal stampings is often automated using conveyor belts and grinding heads. Operators place the stamping on a continuously running conveyor belt, and the grinding heads on both sides of the belt simultaneously grind one pair of edges. After one sidewall is ground, the workpiece is placed back on the conveyor belt, its orientation adjusted so that the other pair of sidewalls faces the grinding heads, and then a second conveying and grinding process is performed to complete the processing of the remaining edges.

[0004] However, while the aforementioned staged grinding method achieves a certain degree of mechanization, the entire process requires the same workpiece to undergo two loading, positioning, and conveying operations, making the operation cumbersome and the processing efficiency low. Furthermore, positioning errors between the two placements can easily cause changes in the relative position of the workpiece and the grinding head during the second grinding, leading to uneven grinding and affecting the grinding quality. Summary of the Invention

[0006] Therefore, one objective of this application is to provide a stamping edge grinding device that can complete the continuous grinding of the four sides of the stamping part in a single conveying, greatly reducing the clamping and positioning time, simplifying operation, and improving the processing efficiency of edge grinding.

The two connecting plates are respectively connected to the corresponding slides. The two first toothed plates are respectively connected to the corresponding connecting plates.

[0017] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0018] The stamping edge grinding equipment of this application embodiment will be described below with reference to the accompanying drawings.

[0019] like Figures 1 to 6 As shown, the stamping edge grinding equipment of this application embodiment may include two traction chains 1, multiple conveyor plates 2, multiple sets of limiting components 3, and two sets of grinding mechanisms 5.

[0020] Two traction chains 1 are respectively arranged opposite to each other between two support plates 9. Multiple conveyor plates 2 are evenly distributed on the attachments of the traction chains 1. Each conveyor plate 2 is rotatably connected to a support shaft 10 on the side away from the traction chain 1. The end of the support shaft 10 is provided with a bearing plate 11.

[0021] It should be noted that the two traction chains 1 are arranged symmetrically, and the traction chains 1 are meshed with the sprockets. A drive shaft is rotatably connected between the two support plates 9, and the sprockets are mounted on the drive shaft. When the motor drives the drive shaft to rotate, it can drive the two traction chains 1 to rotate in the same direction.

[0022] Furthermore, a connecting piece (not shown in the figure) is provided on the chain link pin of the traction chain 1, and the conveyor plate 2 is connected to the connecting piece. It is understood that the present application can use a chain conveyor to convey the conveyor plate 2. The chain conveyor is a commonly used device in the field, and its specific structure and working principle are existing technologies in the field. It will not be described in detail in this application.

[0023] In the embodiments of this application, the bearing plate 11 and the support shaft 10 are located at the center of the conveying plate 2, and the bearing plate 11 is smaller than the size of the stamping part. When the edge of the stamping part is ground, the stamping part is located at the center of the bearing plate 11.

[0024] The conveyor plate 2 is equipped with a drive assembly 6, which is connected to the support shaft 10.

[0025] It should be noted that the drive assembly 6 can drive the support shaft 10 to rotate 90 degrees and drive the stamping part to rotate 90 degrees in order to switch the edge (side) to be polished.

[0026] The four side walls of the bearing plate 11 are respectively provided with a first sliding groove 111. An extension plate 12 is provided in the first sliding groove 111. A groove 121 is provided through the end of the extension plate 12 away from the first sliding groove 111. A flipping shaft 13 is rotatably connected in the groove 121.

[0027] It should be noted that one end of the extension plate 12 points to the center of the support plate 11. The four extension plates 12 are arranged symmetrically in pairs. The extension plates 12 can be locked to the support plate 11 by bolts. In order to accurately adjust the extension length of the extension plate 12, a scale (not shown in the figure) is provided on the extension plate 12 to achieve precise control of the extension length.

[0028] Furthermore, the extension length of the extension plate 12 can be adjusted individually, thus adapting to square or rectangular stamping parts and expanding its applicability.

[0029] In the embodiments of this application, the flip shaft 13 is horizontally disposed through the groove 121, and one end of the flip shaft 13 extends to one side of the extension plate 12.

[0030] Multiple sets of limiting components 3 are respectively arranged in pairs on both sides of the corresponding support plate 11, and each limiting component 3 is connected to the corresponding flipping shaft 13.

[0031] It should be noted that each bearing plate 11 is equipped with four limiting components 3, which are respectively set with four flip shafts 13. Each pair of limiting components 3 forms a group and is located on both sides of the stamping part to implement the limiting action of the stamping part and improve the stability during grinding. The flip shaft 13 can drive the limiting components 3 to flip to release the limiting action of the stamping part.

[0032] Furthermore, the clamping directions of the two sets of limiting components 3 are perpendicular to each other and can be operated independently to facilitate quick switching of the clamping sides of the stamped part and achieve continuous grinding. For example, the limiting component 3 can be controlled to clamp the first set of side walls alone while the second set of side walls is in the unlimited state, or the limiting component 3 can be controlled to clamp the second set of side walls alone while the first set of side walls is in the unlimited state. After grinding is completed, the limiting components on both sides can be released at the same time to facilitate unloading.

[0033] Each support plate 11 is provided with two adjustment components 4, and the two adjustment components 4 are respectively connected to the limit components 3 of the corresponding group.

[0034] It should be noted that the two adjustment components 4 on the same support plate 11 are staggered, which effectively avoids motion interference. Each adjustment component 4 can synchronously drive its corresponding two limit components 3, thereby achieving rapid clamping and release.

[0035] Two sets of grinding mechanisms 5 are arranged in pairs on the upper surface of the support plate 9, and the two grinding mechanisms 5 are located on both sides of the bearing plate 11.

[0036] It should be noted that there are four grinding mechanisms 5 in this application, with two grinding mechanisms 5 forming a group, and each group is set on a corresponding support plate 9. The distance between the grinding mechanism 5 and the stamping part is adjustable to accommodate stamping parts of various specifications.

[0037] To further clarify the above embodiments, in one embodiment of this application, such as Figure 3 As shown, the limiting component 3 includes a flip plate 31, a limiting plate 32, and a spring 33. The flip plate 31 is mounted on the flip shaft 13 and has a second sliding groove 311. The limiting plate 32 is slidably connected to the second sliding groove 311. The two ends of the spring 33 are connected to the limiting plate 32 and the flip plate 31, respectively.

[0038] It should be noted that the flip plate 31 is an L-shaped plate. The flip plate 31 can rotate 90 degrees with the flip shaft 13 and drive the limit plate 32 to rotate 90 degrees to release the restriction on the stamping part. At the same time, it can also ensure that the edge of the stamping part is exposed, providing an operable space for grinding operations.

[0039] Furthermore, the limiting plate 32 moves along the length of the second slide groove 311. When the limiting plate 32 contacts one end of the stamping part, the spring 33 is in a compressed state. The two opposing limiting plates 32 clamp the stamping part above the bearing plate 11, which improves the stability during grinding.

[0040] In one embodiment of this application, such as Figure 4 As shown, the adjustment assembly 4 includes a first slide module 41, two connecting plates 42, two first toothed plates 43, and two first gears 44. The first slide module 41 is mounted on the support plate 11, and two slides are slidably connected to the first slide module 41. The two connecting plates 42 are respectively connected to the corresponding slides, the two first toothed plates 43 are respectively connected to the corresponding connecting plates 42, and the two first gears 44 are respectively disposed on the corresponding flip shafts 13 and respectively mesh with the corresponding first toothed plates 43.

[0041] It should be noted that the first slide module 41 is located on one side of the support shaft 10, and the two slides on the first slide module 41 move in opposite directions. Each bearing plate 11 is equipped with two mutually perpendicular first slide modules 41. When the bearing plate 11 is above the traction chain 1, the first slide module 41 is installed on the lower surface of the bearing plate 11.

[0042] Furthermore, when the first slide module 41 is started, the two connecting plates 42 connected to it move closer to each other under the action of the slide. With the cooperation of the two first toothed plates 43, the two first gears 44 move in opposite directions, realizing the synchronous flipping action of the two limit components 3.

[0043] In one embodiment of this application, such as Figure 3 As shown, the drive assembly 6 includes a drive member 61, a second toothed plate 62, and a second gear 63. The drive member 61 is disposed on the conveyor plate 2, and the output end of the drive member 61 is connected to the second toothed plate 62. The second gear 63 is disposed on the support shaft 10 and meshes with the second toothed plate 62.

[0044] It should be noted that the driving component 61 can be an electric push rod. After the driving component 61 is started, under the cooperation of the second toothed plate 62, it drives the second gear 63 to rotate 90 degrees, thereby causing the support shaft 10 to rotate and the edge of the stamping part to exchange positions so as to facilitate the grinding of another set of edges.

[0045] Furthermore, the moving length of the second toothed plate 62 can be achieved by controlling the extension and retraction stroke of the drive component 61, wherein the extension and retraction stroke of the drive component 61 can be precisely controlled by the controller to ensure the rotational accuracy of the support shaft 10.

[0046] In one embodiment of this application, such as Figure 1 As shown, the grinding mechanism 5 includes a second slide module 51 and a grinding machine 52. The second slide module 51 is disposed on the upper surface of the support plate 9, and the grinding machine 52 is disposed on the slide of the second slide module 51.

[0047] It should be noted that the second slide module 51 is perpendicular to the conveying direction of the conveyor plate 2, and the second slide module 51 facilitates the adjustment of the distance between the grinding machine 52 and the stamping part.

[0048] Furthermore, the grinding machine 52 includes a motor and a grinding head. The motor is mounted on the slide of the second slide module 51. The grinding head is connected to the output end of the motor and fits against the edge of the stamped part. It is understood that the specific structure and working principle of the grinding machine 52 are existing technologies and will not be described in detail in this application.

[0049] Furthermore, such as Figure 2 As shown, the slide of the second slide module 51 is provided with a support 8, and the top of the support 8 is provided with a waste trough 7. The grinding machine 52 is partially located inside the waste trough 7.

[0050] In the embodiments of this application, the inner lower wall of the waste trough 7 is inclined (the end near the grinding head is higher). The waste trough 7 can receive the waste generated by grinding and accumulate at the bottom of the waste trough 7 along the inclined surface. The waste trough 7 and the support 8 are detachable, so as to facilitate its dumping.

[0051] Specifically, personnel can place the stamped part to be processed on the conveyor plate 2 and control one of the first slide modules 41 to start, thereby driving the two connecting plates 42 connected to the slide to move away from each other (see attached). Figure 5 (Middle arrow) At this time, with the cooperation of the first toothed plate 43 and the first gear 44, the two flipping shafts 13 are driven to rotate synchronously, which in turn drives the two flipping plates 31 to flip upward synchronously. Finally, the limiting plate 32 synchronously squeezes the two second set of side walls of the stamping part, the spring 33 is compressed, and the stamping part is centrally limited on the conveyor plate 2. It should be noted that at this time, the clamped side (second set of side walls) is located in the waiting area, while the side to be polished (first set of side walls) is located in the polishing station area.

[0052] The stamped part moves with the conveyor plate 2 to the space between the two grinding mechanisms 5. The grinding machine 52 can synchronously grind the first set of side walls of the stamped part. After the first grinding is completed, the relevant personnel control the drive unit 61 to start. The drive unit 61 drives the second toothed plate 62 to move, and through the cooperation of the second gear 63, drives the support shaft 10 to rotate 90 degrees, thereby driving the stamped part to rotate 90 degrees. The work positions of the first set of side walls and the second set of side walls are interchanged. At this time, the second set of side walls of the stamped part rotates to the grinding work position area.

[0053] Then, the controller can start the two first slide modules 41. The two limit components 3 in the grinding station area release the limit on the stamped part, while the two limit components 3 in the waiting area perform the clamping action on the stamped part. The conveyor plate 2 continues to convey the stamped part. When the stamped part moves to the other set of grinding machines 52, the second set of side walls of the stamped part can be ground. A single conveying can realize continuous grinding of the four sides of the stamped part to eliminate burrs, greatly reduce the clamping and positioning time, and improve the grinding efficiency.

[0054] After the second grinding, the stamped part continues to move along with the conveyor plate 2. Finally, the workpiece is conveyed to the unloading position below the traction chain 1, where all the restrictions on the stamped part can be released. At this time, the stamped part can automatically fall into the material trough 14 (see...). Figure 7 Within this range, the blanking process for the stamped part is completed.

[0055] In summary, the stamping edge grinding equipment of this application embodiment can quickly switch the clamping edge of the limiting component by adjusting the component during the conveying of the stamping part, so as to achieve continuous grinding of the four sides of the stamping part to eliminate burrs, greatly reduce the clamping and positioning time, and improve the grinding efficiency.
