Technical Field

[0001] The utility model relates to the technical field of bending dies, in particular to a bending device that avoids scratching a coating. Background Art

[0002] When existing bending devices bend the pins of products, the coating at the bend of the pins is easily scratched during the bending process, thereby causing damage to the product, thereby affecting the product yield and increasing production costs. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a bending device that avoids scratching the coating, which can bend the product 90 degrees in one stop without scratching the coating of the product.

The middle module is used to press the product to move downward, and the pin needle of the product rolls and rubs against the roller, and the pin needle bends when the product moves downward.

[0005] Preferably, a bevel block is provided on the side of the slider away from the roller, one end of the bevel block slides and rubs obliquely with one end of the slider, and an adjustment rod is connected to the end of the bevel block away from the slider, and the adjustment rod rubs obliquely with the end of the bevel block away from the slider.

[0006] Preferably, a first inclined surface is provided on one side of the inclined block and the sliding block where the inclined block and the sliding block rub against each other in an oblique direction, so as to push the block to slide toward the product.

[0007] Preferably, a friction fillet is provided at the oblique sliding friction point between the slider and the inclined block.

[0008] Preferably, a second inclined surface is provided on one side of the adjusting rod and the inclined block where there is oblique sliding friction, so as to promote the movement of the inclined block.

[0009] Preferably, a third inclined surface matching the second inclined surface is provided on one side of the inclined block and the adjusting rod where there is oblique sliding friction, so as to increase the contact area between the inclined block and the adjusting rod.

[0010] Preferably, the slider is rotatably connected to the fixed block via a rotation pin.

[0011] Preferably, side blocks are provided on both sides of the slider, and the two side blocks are rotatably connected to the two ends of the roller respectively to support the rotation of the roller.

[0012] Preferably, a rolling groove matching with the roller is provided on the slider, and the roller is in rolling engagement with the rolling groove.

[0013] The beneficial effects of the utility model are:

[0014] 1. The lower die float block is used to support the product, and the middle die plate presses the product downward. As the product descends, its pins come into contact with the rollers, which rotate to reduce the friction of the pins when they are bent. This effectively protects the coating on the pins and allows the pins to be bent to 90° in one step, avoiding multiple bending steps and reducing production costs.

[0015] 2. The bending angle of the product pin can be adjusted by sliding the slider, the bevel block and the adjustment rod, which is convenient for adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Physical quantities in formulas, unless otherwise specified, should be understood as basic quantities of the International System of Units (SI) basic units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation or integration.

[0027] Example:

[0028] refer to Figure 1 and Figure 2 A bending device for scratch-proof coatings includes a fixed block 1 rotatably connected to a slider 2, which is rotatably connected to the fixed block 1 via a rotating pin 3. A roller 4 is rotatably connected to the slider 2. A lower die float block 5 is positioned on one side of the fixed block 1 to support the position of a product 100. A middle die block 6 is located on the side of the product 100 away from the lower die auxiliary block. The middle die block 6 presses the product 100 downward, causing rolling friction between the pins 200 of the product 100 and the roller 4. As the product 100 moves downward under the pressure of the middle die block 6, the pins 200 come into contact with the roller 4, bending the pins. As the pins 200 of the product 100 move downward, they contact the roller 4, which rotates, reducing friction on the pins 200 and preventing the coating from falling off. Multiple bending devices can be deployed based on the specific needs of the product 100 and the pins 200.

[0029] refer to Figure 1 and Figure 2 To facilitate adjustment of the bending angle of the pin 200, a bevel block 7 is installed on the side of the slider 2 away from the roller 4. One end of the bevel block 7 slides and rubs diagonally against one end of the slider 2. An adjustment rod 8 is connected to the end of the bevel block 7 away from the slider 2, and the adjustment rod 8 rubs diagonally against the end of the bevel block 7 away from the slider 2. Therefore, when the bending angle of the pin 200 is increased, the adjustment rod 8 is adjusted to the right (i.e., moved toward the bevel block 7), causing the bevel block 7 to move downward. This, in turn, drives the slider 2 to roll and squeeze the pin 200 to the right (i.e., move toward the pin 200 of the product 100), thereby reducing the bending angle of the pin 200 of the product 100. The reverse is also true.

[0030] refer to Figure 1 and Figure 2A first inclined surface 71 is provided on one side of the oblique sliding friction between the inclined block 7 and the slider 2, which is used to push the slider to move toward the product 100. A friction fillet 21 is provided at the oblique sliding friction between the slider 2 and the oblique block 7, so that when the oblique block 7 moves downward, the slider 2 moves to the right under the mutual cooperation of the first inclined surface 71 and the friction fillet 21.

[0031] refer to Figure 1 and Figure 2 A second inclined surface 81 is provided on one side of the adjusting rod 8 and the inclined block 7 where they slide and rub against each other obliquely, so that the adjusting rod 8 pushes the inclined block 7 downward by utilizing the second inclined surface 81 .

[0032] refer to Figure 1 and Figure 2 In order to avoid point contact when the second inclined surface 81 of the adjusting rod 8 pushes the inclined block 7 to move downward, a third inclined surface 72 that cooperates with the second inclined surface 81 is provided on the side of the oblique sliding friction between the inclined block 7 and the adjusting rod 8, which is used to increase the contact area between the inclined block 7 and the adjusting rod 8, so that the adjusting rod 8 and the inclined block 7 are in surface contact, reducing the wear of the adjusting rod 8 and the inclined block 7 and increasing the service life.

[0033] refer to Figure 1 and Figure 2 Side blocks 9 are installed on both sides of the slider 2. The two side blocks 9 are rotatably connected to the two ends of the roller 4 respectively to support the rotation of the roller 4. A rolling groove 22 is opened on the slider 2 to match the roller 4. The roller 4 rolls with the rolling groove 22, thereby further supporting the roller 4 and enabling the roller 4 to withstand greater pressure.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
