Description

Technical Field

[0001] The invention relates to the field of shearing and bending devices, and in particular to a shearing and bending device for metal pins of precision components. Background Art

[0002] Precision components such as reed switches or diodes are widely used electronic components in the manufacturing and assembly of electronic devices. The pins of precision components usually need to be bent to meet specific installation and connection requirements. The bending of precision component pins is usually done with manual tools or simple bending devices. Manual bending of pins is not only inefficient, but also difficult to ensure the consistency and accuracy of the bending, which can easily lead to problems such as inaccurate pin bending angles and pin damage, thus affecting the performance and reliability of precision components.

[0003] For this reason, people have designed bending machines for the pins of precision components. Figure 1 As shown in the figure, there are two pins on both sides of the precision component, and the pins need to be bent to a specified angle (such as 90 degrees) during bending. The existing bending machines still have the following defects: 1) During bending, due to the lack of restrictions on the bending direction of the pins, the pins are prone to swing up and down during bending, resulting in the misalignment of the two pins (such as Figure 2 2) Since the pin is made of metal and has a certain degree of deformation ability, the pin will have a slight degree of recovery after bending, resulting in incomplete bending and a smaller bending angle (as shown in Figure 3 as shown).

[0056] See also Figure 4 and Fig.14 A plurality of U-shaped adsorption slots 101 are arranged at equal intervals along the circumferential direction on the feeding tray 1, and the adsorption slots 101 are used to adsorb and limit the precision components 4. The U-shaped adsorption slots 101 facilitate the entry and exit of the precision components 4 without affecting the bending of the bending assembly 3. The loading assembly 2 is installed on one side of the feeding tray 1, and is used to load the precision components 4 toward the adsorption slots 101.

[0057] See also Figure 4 , Figure 5 , Figure 7 and Fig. 9, the bending assembly 3 is installed on the other side of the feeding tray 1, and is used to bend the pins of the precision components 4. The bending assembly 3 includes a bending baffle 311 symmetrically arranged on both sides of the feeding tray 1 and a bending support 312 located on the outside of the bending baffle 311 and capable of reciprocating horizontal motion. The position of the bending baffle 311 corresponds to the pins of the precision components 4, and the bending support 312 reciprocates along the radial direction of the feeding tray 1. A clamping block 313 is slidably installed on the bending support 312, and the clamping block 313 moves along the radial direction of the feeding tray 1. The clamping block 313 can move toward the bending baffle 311 to clamp the pins. A bending angle die 314 is slidably installed on the bending support 312, and the bending angle die 314 can move along the axial direction of the feeding tray 1, and the movement direction of the bending angle die 314 is perpendicular to the movement direction of the bending support 312. The end of the bending die 314 facing the bending baffle 311 is provided with a V-shaped bending groove 3141 for limiting the pin, and the V-shaped bending groove 3141 extends in a straight line direction. The other end of the bending die 314 is provided with an inclined push surface 3142; a plug 315 is installed on the outer side of the bending die 314, and the plug 315 can push the bending die 314 toward the precision component 4 through the inclined push surface 3142. The inclined push surface 3142 is connected to the vertical surface, and the vertical surface can keep the bending die 314 in the feeding state after feeding toward the precision component, and can maintain pressure to reduce the pin recovery amount.

[0058] A bending die is slidably installed on the bending support, one side of the bending die is provided with a V-shaped bending groove, and the other side is provided with an inclined push surface; when bending, the pin can be bent along the extension direction of the V-shaped bending groove to prevent the pin from swinging up and down, with precise limiting and good bending effect; through the cooperation of the inclined push surface and the top head, when bending, the top head can push the bending die toward the precision component through the inclined push surface, so that the bending is more in place, and even if the pin recovers its deformation, the angle requirement can be met to ensure the bending effect.

[0059] In some embodiments, Figures 10 to 12 As shown, a first slide rail 3131 is provided on the pressing block 313, and the pressing block 313 is slidably installed on the end of the bending support 312 through the first slide rail 3131. A first spring 316 is installed between the pressing block 313 and the bending support 312, and the pressing block 313 is drivingly connected to the bending support 312 through the first spring 316. The first spring 316 is used to realize the linkage between the pressing block 313 and the bending support 312, which has a simpler structure and reasonable and reliable operation.

[0060] When the bending support 312 slides toward the feeding tray 1, the bending support 312 pushes the clamping block 313 to separate it from the bending baffle 311, so that the feeding tray can feed the precision components to be bent into the bending baffle 311. When the bending support 312 slides away from the feeding tray 1, the bending support 312 drives the clamping block 313 to move toward the bending baffle 311 through the first spring 316, thereby clamping the pins of the precision components 4 to be bent. Then, driven by the bending support, the V-shaped bending groove of the angle bending die bends the pins, and the head pushes the angle bending die toward the precision components through the inclined push surface.

[0061] In some embodiments, Fig. 9 , Fig.10 and Fig.12 As shown, a cover plate 317 is fixed to the upper end of the bending support 312, and the cover plate 317 is used to limit the bending die 314.

In order to ensure a stable and firm structure, in this embodiment, two width adjustment guide columns 321 are arranged in parallel and at intervals.

A micrometer fixing block 323 is fixed on the width adjustment guide column 321, a micrometer 324 is installed on the micrometer fixing block 323, and the telescopic rod of the micrometer 324 is connected to the corresponding width adjustment seat 322; a third spring 325 is installed between the micrometer fixing block 323 and the width adjustment seat 322, a spring hanging plate 326 is installed on the side end of the micrometer fixing block 323, one end of the third spring 325 is hooked on the width adjustment seat 322, and the other end is hooked on the spring hanging plate 326.

The cam frame 331 is sleeved on the driving cam 332, and the cam frame 331 and the driving cam 332 cooperate, which can drive the bending support 312 to reciprocate horizontally on the one hand, and also facilitate the micrometer 324 to adjust the spacing without interference on the other hand.

The provision of the ball 3151 can reduce friction, reduce noise, and extend the service life. Among them, the elastic force of the spring built in the spring pin is greater than the elastic force of the second spring 318, ensuring that the top 315 can push the angle die 314 to move, thereby ensuring the reliability of the structure.
