Description

Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to a device for processing the bending position of a metal component. Background Art

[0002] Metal plates are widely used. Metal processing generally uses abrasive belts for grinding. At the same time, the surface of the cast metal plate is rough and is polished smooth by grinding. Metal castings have bent parts. Due to their shape, the bent parts are difficult to contact with the grinding equipment, making them difficult to grind.

[0003] In the authorization announcement number CN 116572132 B, the name is a metal component surface grinding device, which proposes two guide brackets that can drive the unfolding roller to rotate, so that the connection line between the two unfolding rollers and the driving roller forms a certain angle, which is beneficial to the grinding of metal parts with bent surfaces.

[0004] In the above patent, the metal parts with bent surfaces can be polished by changing the angle between the unfolding roller and the driving roller, but the bending angle cannot be too large and has certain limitations. It is difficult to drive the sanding belt to operate at many angles of ninety degrees, and the deformation is caused by extrusion, so the extrusion force needs to be controlled. Although excessive extrusion force can fit with the metal plate, it is easy to stop rotating under the action of friction. For this reason, a processing device for rotating the bent part of the metal plate is proposed. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 5 .

[0034] Embodiment 1:

[0035] The present invention provides a technical solution: a metal component bending position processing device, including a base plate 1 for fixing, a limiting layer 2 is fixed at the lower end of the base plate 1, two groups of supporting diagonal rods 3 are arranged on both sides of the limiting layer 2, and an elastic member 11 is connected between the two groups of supporting diagonal rods 3, and a group of support rods 6 is also fixed at the lower end of the limiting layer 2, and an angle change unit 9 is clamped between the groups of support rods 6. A transmission belt 10 is also provided on the outside of the angle change unit 9, and the angle change unit 9 is set at an adjustable angle, which is used to support the transmission belt 10.

[0036] Each group of supporting diagonal rods 3 is provided with two supporting diagonal rods 3, a driving shaft 4 is fixed between the two supporting diagonal rods 3, a long gear 5 that can rotate is sleeved on the outer side of the driving shaft 4, and the two groups of supporting diagonal rods 3 on both sides are symmetrically arranged;

[0037] Two opposing support rods 6 are arranged in a group of support rods 6, and a long gear 2 7 is rotatably arranged between the two support rods 6. The transmission belt 10 is squeezed by the long gear 1 5 and the long gear 2 7. The transmission belt 10 is frame-shaped, and its inner side is supported by the long gear 1 5, the long gear 2 7 and the angle change unit 9. The transmission belt 10 is rectangular and stretched, and can perform transmission motion under the action of driving, so that the outer sanding belt can rotate to achieve grinding.

[0038] The elastic member 11 includes a partition plate 111, a connecting tube 112 and a tension spring 113;

[0039] There are two partitions 111, which are respectively fixed on two groups of supporting diagonal rods 3 on both sides. There are also two connecting tubes 112, which are respectively hinged on the partitions 111 on both sides. The tension spring 113 is in an extruded state, and its two ends are respectively fixed in the connecting tubes 112 on both sides. The transmission belt 10 is supported by the connecting tube 112 to be in an expanded and stretched state. The elastic member 11 is used to support the transmission belt 10 so that its meshing teeth cooperate with the meshing teeth of the long gear 1 5 and the long gear 2 7 to ensure transmission.

[0040] The inner side of the transmission belt 10 and the outer sides of the long gear 1 5 and the long gear 2 7 are all provided with meshing teeth. The meshing teeth on the inner side of the transmission belt 10 cooperate with the meshing teeth on the outer sides of the long gear 1 5 and the long gear 2 7. The outer side of the transmission belt 10 can be fixed with a sanding belt for grinding.

[0041] A motor 8 is fixed on the support rod 6 on one side, and the output end of the motor 8 is meshed with the long gear 2 7, which serves as a driving force to drive the transmission belt 10 for transmission.

[0042] The angle changing unit 9 includes a fixed shaft 94 in the middle and expansion plates 91 on both sides;

[0043] The fixed shaft 94 is detachably fixed between the group of support rods 6, and the expansion plates 91 on both sides are rotatably set on the outside of the fixed shaft 94. A mounting opening 92 is opened on the expansion plate 91, and a round shaft 93 is rotatably installed in the mounting opening 92. The transmission belt 10 is squeezed against the outside of the round shaft 93, and the transmission belt 10 is located on the outside of the two expansion plates 91, also in a triangular shape. The triangular transmission belt 10 can cooperate with the bent part of the metal plate. At the same time, when working, the transmission belt 10 can be polished, and the bent part of the metal plate can be polished.

[0044] An upper sheet 95 is fixed to the upper end of the fixed shaft 94. Both sides of the upper sheet 95 are hinged with hinges 96. The outer side of the hinge 96 is rotatably connected with a threaded shaft 97. The threaded shaft 97 can be twisted. A threaded cylinder 98 is hinged to the outer side of the expansion plate 91. The threaded cylinder 98 is threadedly connected to the threaded shaft 97. The bending degree of the expansion plate 91 is controlled by the threaded cylinder 98 and the threaded shaft 97. The angle of the expansion plate 91 can be intuitively controlled.

[0045] Two circular grooves 99 are arranged circumferentially on the outer side of the fixed shaft 94, and an integrally formed convex layer 901 is provided on the inner wall of the two circular grooves 99. A semicircular fitting piece 902 with upper and lower halves is clamped in each circular groove 99, and the semicircular fitting piece 902 also cooperates with the convex layer 901. An insertion shaft 903 is integrally formed on the outer side of one half of the semicircular fitting piece 902, and the insertion shaft 903 is inserted into the expansion plate 91 to limit the expansion plate 91. The semicircular fitting piece 902 is limited to the fixed shaft 94, and the semicircular fitting piece 902 limits the expansion plate 91, so that the expansion plate 91 is limited and can be adjusted through the threaded tube 98 and the threaded shaft 97.

[0046] When the motor 8 is in operation, the long gear 2 7 is driven to rotate, and the outer transmission belt 10 also rotates, and the elastic member 11 is in an extruded state, so that the two groups of supporting diagonal rods 3 on both sides can be forced to expand outward to support the transmission belt 10, and under the action of the angle changing unit 9, the lower end of the transmission belt 10 is triangular, which can cooperate with the metal plate with an angle. The transmission belt 10 drives the outer sanding belt to rotate during transmission to achieve operation. During the extrusion between the angle changing unit 9 and the metal part, the transmission belt 10 will not be deformed, and the outer side of the transmission belt 10 can be in an angled straight state. During the grinding, the metal part is polished smooth to avoid deformation caused by extrusion, so that the abnormal protruding position remains unchanged. And because the shape of the transmission belt 10 does not change, the degree of extrusion can be controlled at any time to avoid the situation of non-rotation.

[0047] By rotating the threaded shaft 97, the threaded barrel 98 can be controlled to change the rotation angle of the expansion plate 91, so that the expansion plate 91 can be attached to metal plates with different requirements, which is convenient for control;

[0048] Secondly, the circular shaft 93 is set, and the circular shaft 93 is pressed against the transmission belt 10, and the outer side of the transmission belt 10 is pressed against the metal plate, which originally produces friction with the metal plate. The inner side of the transmission belt 10 rolls and rubs against the circular shaft 93, and is set in a triangular shape, which can fit with the metal parts relatively and reduce friction. The transmission belt 10 has a meshing setting, which can realize rotation to the greatest extent and avoid jamming.

[0049] See also Figure 6-Figure 7 .

[0050] Embodiment 2:

[0051] On the basis of the first embodiment, the upper plate 95 is extended upward, and an upper shaft 951 is rotatably mounted on the upper end thereof. After the two expansion plates 91 are turned over, the transmission belt 10 can be pressed against the upper shaft 951 .

[0052] Two opposite limit blocks 904 are also fixed to the lower end of the fixed shaft 94 , and a lower shaft 905 is rotatably mounted between the two limit blocks 904 . The lower shaft 905 is used to contact the transmission belt 10 .

[0053] The lower shaft 905 provided at the lower end can be rotated to be used for squeezing with the transmission belt 10, and can also plasticize the transmission belt 10 so that it can extend into the corner of the bent metal plate, and grind deeper, without being affected by the squeezing force, and can also grind deeper, making it easier to control;

[0054] When the fixed shaft 94 is loosened and flipped 180 degrees so that the concave side of the angle change unit 9 faces outward, the protruding side of the bent metal plate can be polished. Since the two expansion plates 91 are opened, the transmission belt 10 squeezed on the outside moves along the outside of the two expansion plates 91. When squeezing the protruding side of the metal plate, the transmission belt 10 can be squeezed and moved between the two expansion plates 91, that is, the transmission belt 10 covers the protruding side of the metal plate for comprehensive cleaning. Secondly, when the extrusion force is large, the transmission belt 10 can be offset against the upper shaft 951 to avoid affecting the movement. It also has a limiting function to avoid excessive deformation.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
