Description

Technical Field

[0001] The utility model belongs to the field of metal processing, in particular to a trimming device for metal product processing. Background Art

[0002] Metal product trimming refers to a process operation in the process of metal material processing, which is mainly the process of trimming the edges of metal plates, strips, pipes or other profiles. During metal production or further processing, due to restrictions in the manufacturing process or requirements for subsequent use, the edges of the original metal materials are often uneven, rough, cracked or in other undesirable conditions. Therefore, it is necessary to remove the burrs to improve the quality and appearance of the final product. When processing some can-type metal products, it is generally necessary to trim the openings. The commonly used processing method is to accurately install the can on the trimming machine, use a fixture or tooling to stabilize the can to prevent movement or deformation during the cutting process, turn on the machine, and use mechanical or hydraulic drive to make the tool cut the edge of the can along a predetermined trajectory. In some cases, the horizontal rotary cutting principle is used, that is, the tool rotates while cutting along the side wall of the can. At this time, the cut ring waste will fall under the workbench, keeping the working area clean and preventing waste splashing to cause safety risks. The ring waste needs to be removed in time, but this greatly affects the processing efficiency and safety. For this reason, we designed a trimming device for metal product processing.

The movable ends of the telescopic rods 14 are respectively fixedly connected to the lower sides of the first ring 13, and the first ring 13 is fixedly mounted with a first rack 15 through a connecting rod. One side of the first rack 15 is meshingly matched with a gear 16, and the gear 16 is rotatably mounted on the base plate 1, and the other side of the gear 16 is meshingly matched with a second rack 17. The first rack 15 and the second rack 17 are respectively passed through and movably mounted in reserved holes provided on the base plate 1, and the second rack 17 is movably mounted on the base plate 1 through a spring rod 18, and the fixed end of the spring rod 18 is fixedly connected to the lower side of the base plate 1, and the movable end of the spring rod 18 is fixedly connected to the second rack 17, and a pedal 19 is fixedly mounted on the lower end of the second rack 17. The utility model has a simple structure and an ingenious design. The workpiece 100 and the removed waste can be lifted upward by pedaling, which makes it easy to remove the workpiece 100 and the waste. The utility model can meet actual needs and is suitable for promotion.When using the utility model, firstly, the first electric push rod 4 and the second electric push rod 11 are reset respectively, and then the workpiece 100 is turned upside down on the support table 6, at which time the upper side of the inner wall of the workpiece 100 is in contact with the upper side of the support table 6, and then the button 12 responsible for starting is pressed, and the controller 10 transmits a signal to extend the first electric push rod 4 until the pressure block 5 presses the workpiece 100 to position the workpiece 100, and then the controller 10 transmits a signal to rotate the output shafts of the first motor 7 and the second motor 8 respectively, and the output shaft of the first motor 7 rotates to drive the support table 6, the workpiece 100 and the pressure block 5 The output shaft of the second motor 8 rotates to drive the cutting wheel 9 to rotate, and then the controller 10 transmits a signal to extend the second electric push rod 11, so that the cutting wheel 9 trims the workpiece 100. After the trimming is completed, the second electric push rod 11 is shortened in turn, the first motor 7 stops rotating, the first electric push rod 4 is shortened, and then the foot pedal 19 moves the second rack 17 downward, and the second rack 17 moves downward to drive the gear 16 to rotate, and then drives the first rack 15 to move upward, so that the first ring 13 pushes the workpiece 100 and the waste upward to facilitate the removal of the workpiece 100 and the waste.

[0017] Specifically, as shown in the figure, the lower side of the support platform 6 in this embodiment is rotatably mounted with a coaxial support tube 20 via a bearing, and the support tube 20 is fixedly mounted on the bottom plate 1. The support tube 20 can increase the stability of the support platform 6 during rotation.

[0018] Further, as shown in the figure, the support tube 20 and the bottom plate 1 of the present embodiment are respectively provided with a plurality of heat dissipation holes 30. The presence of the plurality of heat dissipation holes 30 facilitates heat dissipation of the first motor 7 during operation.

[0019] Furthermore, as shown in the figure, in this embodiment, the second ring 40 is rotatably mounted on the first ring 13 via a bearing, and the second ring 40 is in clearance with the outer periphery of the support platform 6. When the vertical dimension of the workpiece 100 to be trimmed is too large, causing the lower side of the workpiece 100 to contact and fit with the second ring 40, under the action of the bearing between the second ring 40 and the first ring 13, when the first motor 7 drives the support platform 6 and the workpiece 100 to rotate, it is possible to prevent the workpiece 100 from being deformed during trimming due to excessive friction between the workpiece 100 and the second ring 40.

[0020] Furthermore, as shown in the figure, in this embodiment, a stopper 50 is fixedly installed on the second rack 17. The presence of the stopper 50 can prevent the spring rod 18 from being overstretched when the foot steps on the pedal rod 19, thereby extending the service life of the spring rod 18.
