Description

Technical Field

[0001] This utility model relates to the field of dust cover processing technology, and in particular to a feeding device for dust cover stamping. Background Technology

[0002] Dust covers are widely used in the automotive, machinery, bearing, and electronics industries. For example, bearing dust covers prevent dust and impurities from entering the bearing, extending its lifespan. Stamping is a common metalworking process used to manufacture dust covers of various shapes and sizes. The stamping process for dust covers typically employs automated feeding devices to improve production efficiency and safety.

[0003] The strip conveying mechanism for stamping described in announcement number CN217044214U includes a feed track on one side of the die for conveying the strip to the die, an discharge track on the opposite side of the die for discharging the strip out of the die, a support above the discharge track, a first cylinder fixedly connected to the support, a slider mounted on the piston rod end of the first cylinder, the slider moving along the support, and a deflecting rod hinged to the slider and passing through a stamping hole in the strip, and a limiting stop fixedly connected to the slider and abutting the deflecting rod. The limiting stop is located between the deflecting rod and the die, and the deflecting rod moves with the first cylinder and drives the strip to be discharged gradually.

[0004] Based on the above technical features, the problem is that the existing conveying mechanism only limits the unprocessed end of the material strip, and the stamped end has a large amount of movement. As a result, during stamping, the stamped end moves due to the force of the stamping head, which causes the actuating rod to misalign with the stamping hole on the stamped material strip, affecting subsequent stamping processing.

[0005] Therefore, it is necessary to solve the above problems by using a feeding device for dust cover stamping. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1 to 5 The shown is a feeding device for stamping a dust cover, comprising two support frames 5 respectively located on the left and right sides of a stamping machine 1. A strip 2 is placed horizontally along the left-right direction on the stamping table of the stamping machine 1. The left side of the strip 2 has punched holes 3, indicating it has already undergone stamping, while the right side of the strip 2 has no punched holes 3 and is awaiting stamping. The left side of the strip 2 is located on the support frame 5 on the left side of the stamping machine 1, and the right side of the strip 2 is located on the support frame 5 on the right side of the stamping machine 1.

[0023] Each of the two support frames 5 is fixedly connected to the stamping machine 1 with a limiting component, and the strip 2 is slidably fitted with the two limiting components. The following description uses one of the limiting components as an example; the other is identical.

[0024] The limiting component includes a limiting block 4 fixedly disposed between the support frame 5 and the stamping machine 1. A limiting groove is formed on the top of the limiting block 4 in the horizontal direction. The vertical cross-section of the limiting groove is inverted T-shape, and the limiting groove passes through the limiting block 4 in the horizontal direction. The strip 2 passes through the limiting groove of the limiting block 4 in the horizontal direction and slides with the limiting block 4 in a limiting engagement.

[0025] A driving roller 10 and a driven roller 6 are rotatably mounted on each of the two support frames 5. The driving roller 10 and driven roller 6 on one of the support frames 5 will be described as an example, and the driving roller 10 and driven roller 6 on the other support frame 5 are the same.

[0026] The driving roller 10 and driven roller 6 on the support frame 5 are parallel to each other and arranged horizontally in the front-to-back direction. The driving roller 10 is located directly above the driven roller 6, and the driven roller 6 is rotatably connected to the support frame 5. The material belt 2 is sandwiched between the driving roller 10 and the driven roller 6, and the driving roller 10 and the material belt 2 are in abutting and driving engagement. A rubber ring is fitted on the driving roller 10, and the rubber ring is in abutting and driving engagement with the material belt 2.

[0027] The support frame 5 is equipped with a first power component that drives the active roller 10 to move up and down, and a second power component that drives the active roller 10 to rotate intermittently.

[0028] The first power assembly includes two movable seats 8, with a drive roller 10 positioned horizontally between the two movable seats 8 and rotatably connected to them. Two electric push rods 7 are fixedly mounted on the support frame 5, each corresponding to one of the two movable seats 8. The telescopic shaft of each electric push rod 7 is vertically upward and fixedly connected to the corresponding movable seat 8.

[0029] The second power assembly includes a motor 9, which is fixed to a mounting plate 11, which is fixed to a movable base 8. A grooved wheel 12 and a drive dial 13 are rotatably mounted on the mounting plate 11. The grooved wheel 12 is connected to the drive roller 10 for transmission. A rotating shaft is rotatably mounted on the mounting plate 11, and the rotating shaft is coaxially and fixedly connected to the drive roller 10. The grooved wheel 12 is fixedly sleeved on the rotating shaft and fixedly connected to the rotating shaft.

[0030] The active dial 13 is coaxially and fixedly connected to the output shaft of the motor 9. A cylindrical pin is fixedly installed on the active dial 13, and the cylindrical pin slides in engagement with the transmission groove on the grooved wheel 12, while the cylindrical pin and the grooved wheel 12 abut against each other in a transmission engagement.

[0031] In this embodiment, the grooved wheel 12, the cylindrical pin, and the active dial 13 together form a Maltese mechanism.

[0032] Working principle: During the stamping process of the dust cover, the raw material for making the dust cover, i.e., the material strip 2 for making the dust cover, is first passed horizontally from right to left between the drive roller 10 and the driven roller 6 on the support frame 5 located on the right side of the stamping machine 1. Then, the two electric push rods 7 on the support frame 5 located on the right side of the stamping machine 1 are activated. The telescopic shafts of the two electric push rods 7 on the support frame 5 retract downward and drive the connected moving seat 8 to move downward. At this time, the two moving seats 8 drive the connected drive roller 10 to move downward. After the drive roller 10 clamps the material strip 2 with the driven roller 6 below, the two electric push rods 7 on the support frame 5 are stopped.

[0033] Next, the motor 9 on the support frame 5 located on the right side of the press 1 is started. The output shaft of the motor 9 drives the connected drive dial 13 to rotate, and the drive dial 13 drives the cylindrical pin to revolve around the output shaft of the motor 9. During the revolution of the cylindrical pin, it slides into the transmission groove of the grooved wheel 12, and at the same time, the cylindrical pin pushes the grooved wheel 12 to rotate 90 degrees clockwise. The grooved wheel 12 drives the connected rotating shaft to rotate synchronously, and the rotating shaft drives the connected drive roller 10 to rotate synchronously. The drive roller 10 pushes the material belt 2 to move horizontally to the left a certain distance.

[0034] During this process, the strip 2 slides through the limiting groove of the limiting block 4 on the right side of the press 1. When the strip 2 reaches the stamping table of the press 1, the press 1 performs the stamping operation. As the drive roller 10 on the support frame 5 on the right side of the press 1 rotates intermittently, the strip 2 slides through the limiting groove of the limiting block 4 on the left side of the press 1, and gradually passes between the drive roller 10 and the driven roller 6 on the support frame 5 on the left side of the press 1.

[0035] At this time, the two electric push rods 7 on the support frame 5 located on the left side of the press 1 are activated. The telescopic shafts of the two electric push rods 7 on the support frame 5 retract downward and drive the connected moving seat 8 to move downward. The two moving seats 8 drive the connected drive roller 10 to move downward. After the drive roller 10 clamps the material belt 2 with the driven roller 6 below, the two electric push rods 7 on the support frame 5 are turned off.

[0036] At the same time, the motor 9 on the support frame 5 on the left side of the press 1 is started, and the output shaft of the motor 9 is made to rotate synchronously with the output shaft of the motor 9 on the support frame 5 on the right side of the press 1, thereby causing the two drive rollers 10 to push the material belt 2 to slide horizontally from right to left.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
