A number of electronic components are often welded on PCB boards. Electronic components are a general term for electronic components such as capacitors, transistors, hairsprings, and springs. The pins of electronic components are wires that are connected to the peripheral circuits from the internal circuits of electronic components. All the pins constitute the interface of the electronic components. In the production process of electronic components, the pins of the electronic components are usually sheared and formed after production, so that the pin size of the electronic components is within the tolerance range, which is convenient for installation on the PCB board, with better consistency and more beautiful appearance.

[0026] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 9 The pin cutting machine with pin shaping shown in the figure comprises a frame 1, the frame 1 is provided with an operating table 2, a pin cutting middle plate 3 connected to the operating table 2, the pin cutting middle plate 3 is provided with a first forming groove 30 for the pin to extend into, the operating table 2 is provided with a slide 4, a forming template 5 located on the slide 4 and can extend into the first forming groove 30 to cooperate with the pin pushing and shaping, a cutter 6 connected to the lower side of the forming template 5, and a driving device 7 connected to the forming template 5. The utility model integrates the two steps of pin shaping and cutting into the pin cutting machine, and can realize fast and consistent pin shaping and pin cutting operations by utilizing the continuity of shaping and cutting actions, reducing the inconvenience caused by manual operation, realizing the simplification of the operation process and the improvement of production efficiency, and effectively reducing the product failure rate and production cost.

[0028] Optionally, in some embodiments, the pin cutting machine with pin shaping of the present invention uses a hydraulic station as a power source and a hydraulic cylinder as a driving element to drive a cutter to simultaneously shape and cut multiple electronic component pins with large cross-sections of 10-100 mm2.

[0029] Optionally, in some embodiments, the operator first places the electronic component on the operating table, so that the pin extends into the first forming groove, and drives the forming template to slide in the slide groove through the driving device and cooperate with the first forming groove to push and shape the pin, so that the pin is shaped into the desired shape. When the shaping is completed, the cutter moves with the forming template to cut off the excess pin part that extends into the first forming groove and is located below the forming template. After the cutting is completed, the forming template is reset and drives the cutter away from the first forming groove. By cyclically performing the above steps, the electronic components can be shaped and cut for many times. At the same time, there is no need to separate the two steps of pin shaping and cutting, which reduces the material handling and intermediate processing links, shortens the production cycle, and improves production efficiency. At the same time, due to the automation of the entire process, it also reduces the labor intensity of the operator, improves the consistency of work and product quality.

[0030] Optionally, in some embodiments, the driving device may be electric, pneumatic or hydraulic, etc., so as to ensure the stability and accuracy of the mechanical action.

[0031] like Figures 4 to 7The pin cutting machine with pin shaping shown in the figure, the forming template 5 includes a pin cutting push plate 51, a cutter push plate assembly 52 connected to the driving device 7, and a push strip assembly 53 connected between the pin cutting push plate 51 and the cutter push plate assembly 52, and the cutter push plate assembly 52 is provided with a cutter push plate accommodating cavity 520 for accommodating the cutter 6. Further, as a preferred embodiment of the utility model but not a limitation, through the cooperation of various components of the forming template, the shaping and shearing of the pins of electronic components are realized, the accuracy and stability of the operation are effectively improved, and the consistency and quality of the pins are ensured. Specifically, the cutter push plate assembly can move in the direction of the first forming groove under the drive of the driving device and accurately push the cutter to cut the pin, ensuring that the shearing force is uniform and the position is accurate each time. The push strip assembly is located between the pin cutting push plate and the cutter push plate assembly, and plays the role of transmitting and converting force, so that the power output from the driving device can synchronously drive the pin cutting push plate to move in the direction of the first forming groove and perform a shaping operation on the pin.

[0032] like Figures 4 to 7 In the pin cutting machine with pin shaping shown in the figure, the driving device 7 is provided with a pushing part 71, and the cutter push plate assembly 52 includes a pusher block 521 connected to the pushing part 71, and a cutter push plate 522 connected to the pusher block 521. Further, as a preferred embodiment of the utility model but not a limitation, through the coordinated work between the pushing part, the pusher block and the cutter push plate, the driving device can accurately and quickly drive the cutter push plate assembly to move, thereby realizing the shaping and cutting of the pins of electronic components. This design not only improves production efficiency and reduces production costs, but also improves the stability and durability of the equipment by optimizing the structure and connection method of each component.

[0033] Optionally, in some embodiments, the pushing portion is an axial piston, and the pusher block is sleeved on the outside of the pushing portion. The pushing portion converts the power output of the driving device into linear motion to drive the cutter push plate assembly to move linearly. The pusher block and the cutter push plate are connected by fasteners such as screws, bolts, etc.

[0034] like Figures 4 to 7The pin cutting machine with pin shaping shown in the figure, the push bar assembly 53 includes a push bar connection seat 531 connected to the cutter push plate 522, a push bar 532 that can be connected to the pin cutting push plate 51, and an elastic assembly 533 located between the push bar connection seat 531 and the push bar 532, the elastic assembly 533 includes a plurality of connecting shafts 5331 passing through the push bar connection seat 531 and connected to the push bar 532, and an elastic member 5332 sleeved on the outside of the connecting shaft 5331 and abutting against the push bar connection seat 531 and the push bar 532. Further, as a preferred embodiment of the utility model but not limited thereto, the push bar is connected to the pin cutting push plate, and can transmit the power transmitted from the driving device to the pin cutting push plate, thereby realizing the precise shaping operation of the pins of the electronic components. The push bar connection seat is connected to the cutter push plate, serving as a bridge for the linkage between the shaping of the pin cutting push plate and the action of the cutter. A plurality of connecting shafts pass through the push bar connecting seat and are fixedly connected to the push bar, and they play the role of connection and guidance, so as to ensure that the push bar can move smoothly and accurately.

[0035] Specifically, the elastic member is made of a spring or other elastic material, and is located between the push bar connecting seat and the push bar, and is used to provide appropriate buffering and resetting functions to ensure stability and accuracy during the shearing and forming process.

[0036] Specifically, the elastic member is sleeved on the outside of the connecting shaft. When the push-bar connecting seat is forced to move toward the first forming groove, the push-bar connecting seat pushes the push bar through the connecting shaft, thereby driving the cutting foot push plate to abut against the cutting foot middle plate. The push-bar connecting seat continues to move toward the first forming groove and abuts against the elastic member, and the elastic member is compressed between the push-bar connecting seat and the push bar. When the external force disappears, the elastic member can make the push-bar connecting seat rebound to the initial position through its own restoring force, and the connecting shaft drives the push bar to reset, and the cutting foot push plate is no longer pushed to the cutting foot middle plate. Such a structure not only protects the mechanical structure, but also ensures a smooth transition between various processes in continuous operation.

[0037] like Figures 4 to 7 In the pin cutting machine with pin shaping shown in the figure, the cutter push plate 522 is provided with a cutter push plate connection hole 5221 and a fastener 5222, the cutter 6 is provided with a cutter connection hole 61, and the fastener 5222 passes through the cutter push plate connection hole 5221 and the cutter connection hole 61, so that the cutter 6 is connected to the cutter push plate 522. Further, as a preferred embodiment of the utility model but not a limitation, such a design can ensure that the cutter is firmly connected to the cutter push plate, ensuring that the cutter moves stably during the cutting process, and the fastener cannot fix the connection between the cutter and the cutter push plate to prevent loosening or falling off during use, and can also facilitate the removal, replacement or sharpening of the cutter, thereby improving the working efficiency and service life of the equipment.

[0038] like Figure 2 In the pin cutting machine with pin shaping shown in the figure, the cutter push plate 522 is provided with a second forming groove 5220, the first forming groove 30 and the second forming groove 5220 enclose a forming cavity 8 for pushing and shaping the pin, and the horizontal axis of the forming cavity 8 forms an angle α with the horizontal moving direction of the cutter push plate 522, and the angle α is between 0-90 degrees. Through the angle α, when the cutter push plate 51 is opened, the size of the first forming groove 30 becomes larger, so that the pins with inconsistent sizes that have not been formed can be more conveniently inserted into the first forming groove 30. Further, as a preferred embodiment of the utility model but not a limitation, the first forming groove is located on the cutter middle plate, and the second forming groove is provided on the cutter push plate. When the cutter push plate moves and cooperates with the cutter middle plate, the first forming groove and the second forming groove together enclose a closed space, the pin to be processed is placed in the forming cavity, and the drive force of the drive device causes the cutter push plate to move in a specific direction to push and shape the pin. Due to the existence of the forming cavity, the pin will be subjected to a more uniform force when pushed, so it is easier to form the expected shape. The setting of the forming cavity can reduce the resistance and friction of the pin during the shaping process, reduce the energy consumption and wear of the equipment, and improve the overall performance and life of the equipment. Figure 2 As shown, the moving direction of one of the cutter push plates 522 is N, and the moving direction of the other cutter push plate 522 is M. The moving direction of one of the cutter push plates 522 is N and forms an angle α with the horizontal axis of the forming cavity 8. Similarly, the moving direction of the other cutter push plate 522 is M and forms an angle α with the horizontal axis of the forming cavity 8. The range of the angle α is set between 0-90 degrees. Different angles α will cause the pin to be subjected to different shearing and bending forces, thereby affecting the shaping effect.

[0039] In the prior art, it is necessary to push in four directions, front, back, left, and right, to form the pin. The utility model forms left and right thrusts in two directions by moving the cutter push plate and cooperating with the pin cutting middle plate. By setting the angle α, it not only reduces the push of the pins in the front and back directions, but also clamps the pins in the left and right directions. Moreover, the setting of the angle α can enhance the effect of the pins being pushed and formed. As the angle α increases, the direction of the thrust will gradually deviate from the axis direction of the forming cavity, and the effect of the bending force will also be enhanced. The pre-forming angle of the pin before shearing can be adjusted according to actual needs to meet the assembly requirements of different electronic products or improve the welding quality.

[0040] like Figures 4 to 7In the pin-cutting machine with pin shaping shown, the push bar 532 is provided with a connection interface 5321 extending between the pin-cutting push plate 51 and the cutter 6. Optionally, in some embodiments, the pin-cutting push plate and the cutter do not need to be provided with additional fasteners, and the setting of the connection interface facilitates the replacement of the pin-cutting push plate. Further, as a preferred embodiment of the utility model but not a limitation, the connection interface can increase the stability of the push bar during the movement process during the cutting process, prevent it from shaking or offsetting due to uneven force, and help maintain the efficiency and consistency of the entire electronic component pin shaping and shearing process. The connection interface can effectively reduce the direct impact force of the push bar on the pin-cutting push plate or the cutter, play a role in shock absorption and buffering, help reduce the impact of vibration and vibration on the cutting quality, ensure the smooth operation of the equipment and reduce noise. At the same time, the setting of the connection interface allows the cutter to be closer to the pin-cutting push plate, while reducing the wear between the cutter and the pin-cutting push plate.

[0041] Optionally, in some embodiments, a connection interface having elasticity is engaged between the cutting foot push plate and the cutting knife.

[0042] Optionally, in some embodiments, when the cutter is reset, the cutter and the push bar simultaneously drive the cutting foot push plate to move a certain distance through the connection interface, so that the cutting foot push plate is separated from the cutting foot middle plate.

[0043] like Figures 2 to 7 In the pin cutting machine with pin shaping shown in the figure, the operating table 2 is provided with a support plate 21 for fixing the pin cutting middle plate 3, the support plate 21 encloses the slide groove 4, the support plate 21 is provided with a limiter 213 for limiting the forming template 5, and a pin cutting pressure plate 9 located on the upper side of the pin cutting middle plate 3, the pin cutting pressure plate 9 is provided with a pin cutting pressure plate opening 91 for the pin to extend into. Optionally, the slide groove enclosed by the support plate is quadrilateral, preferably rectangular. The support plate can fix the pin cutting middle plate to ensure the stability and accuracy of the cutter push plate assembly 52 during operation. The structure and strength of the support plate must be able to withstand the weight, pressure and relative shear force from the pin cutting middle plate, the forming template and other working parts. The slide groove is used for the movement of the cutter push plate assembly 52 (including the forming template) to ensure its accuracy and stability when cutting the pins.

[0044] Further, as a preferred embodiment of the present invention but not a limitation, the limiter is used to limit the position and range of motion of the forming template to ensure that it will not shift or tilt during operation. Specifically, the limiter is a pressure block disposed on the upper side of the cutter push plate, and the limiter is connected to the support plate through a fastener, which can press and limit the loose movement of the cutter push plate.

[0045] Furthermore, as a preferred embodiment of the present invention but not a limitation, the cutting foot pressure plate is located on the upper side of the cutting foot middle plate, and is used to fix and support the pin to be processed. During operation, the pin extends into the first forming groove through the opening of the cutting foot pressure plate, and then is sheared by the cutting blade push plate assembly. Specifically, the opening of the cutting foot pressure plate is rectangular, and this shape can adapt to the shape of most pins, while ensuring that the pin has stable support during the shearing process. Optionally, in some embodiments, such as Figure 3 As shown, the cutting foot pressure plate opening is tilted, and the angle β between the midline between its longest sides and the moving direction M of the cutting foot push plate is complementary to the angle α. In this way, the cutting foot pressure plate opening is tilted, which can make the pins move more easily in a predetermined direction when subjected to shearing force, thereby improving the shearing efficiency and quality. The tilted cutting foot pressure plate opening and the corresponding angle β can make the pins move more smoothly during the shearing process, reduce resistance and friction, thereby improving the shearing efficiency and quality. Because the angle α makes the arrangement of multiple part pins form an angle with the cutting edge, when the cutter is shearing, it cuts single pins in turn, and the shearing force of the cutter cutting multiple pins at the same time is greatly reduced compared to the cutter without angle α.

[0046] Optionally, in some embodiments, the cutting foot pressure plate opening is tilted, and the angle β between the midline between the longest sides and the moving direction of the cutting foot push plate is equal to the angle α. In this way, the cutting foot pressure plate opening is tilted, which can make it easier for the pin to move along a predetermined direction when subjected to shearing force, thereby improving the shearing efficiency and quality. The tilted cutting foot pressure plate opening and the corresponding angle β can make the pin move more smoothly during the shearing process, reduce resistance and friction, and thus improve the shearing efficiency and quality.

[0047] Furthermore, as a preferred embodiment of the utility model but not a limitation, a first detection probe 211 and a second detection probe 212 are provided on the support plate. The first detection probe is used to detect whether the push knife block is successfully reset, and the second detection probe detects whether the push knife block is moved to a specified position. When the push knife block moves to the specified position, the cutter can smoothly cut off excess pins. The second detection probe can limit the driving device from continuing to move toward the first forming groove through the controller. When the first detection probe detects that the push knife block has not been successfully reset, the first detection probe detects and transmits a signal through the controller to inform the operator to perform maintenance and repairs on the equipment. For example, splashed pins may get stuck in the forming template, which may cause damage to the machine when it is forced to start. Specifically, a starting module, a switch module, a detection module and an indication module are provided on the control circuit of the controller. The start and stop of the hydraulic cylinder are controlled by the starting module on the controller, and the operating position of the hydraulic cylinder is detected by the first detection probe 211 and the second detection probe 212. After exceeding the limit threshold, the controller controls the switch by controlling the switch module, and indicates the switch control result through the indication module. This can effectively avoid the situation where the electromagnetic coil is burned or other accidents occur due to untimely indication after short circuit, open circuit and other phenomena occur in the electromagnetic coil, so that the use of the hydraulic device is safer, more reliable and more stable. The first detection probe 211 and the second detection probe 212 send the position signal to the control circuit, and control the solenoid valve through circuit logic, so that the hydraulic station works in a no-load state, thereby achieving unloading energy saving.

[0048] Optionally, in some embodiments, the foot cutting push plate includes a left foot cutting push plate located on the left side of the foot cutting middle plate, a left second forming groove located on the left foot cutting push plate, a right foot cutting push plate located on the right side of the foot cutting middle plate, and a right second forming groove located on the right foot cutting push plate, the first forming groove includes a left first forming groove for the left foot cutting push plate to extend into, and a right first forming groove for the right foot cutting push plate to extend into, the left foot cutting push plate and the right foot cutting push plate are centrally symmetrically arranged, and the left first forming groove and the right first forming groove are centrally symmetrically arranged. Furthermore, as a preferred embodiment of the present invention but not a limitation, the left first forming groove and the right first forming groove are symmetrically arranged at the center position. Such a design can ensure that the position of the left first forming groove matches the position of the left second forming groove, and the position of the right first forming groove matches the position of the right second forming groove, so as to achieve accurate positioning and matching of the pins during the forming process. The left cutting foot push plate and the right cutting foot push plate are symmetrically arranged at the center position. The left cutting foot push plate and the right cutting foot push plate can push the pins independently respectively, so as to ensure that the left cutting foot push plate and the right cutting foot push plate can move and form symmetrically relative to the cutting foot template at the same time, so as to ensure the consistency and stability of the pins. When there are multiple pins of an electronic component and they are symmetrically arranged, the pin located on the left side of the electronic component can be formed in the forming cavity formed by the left first forming groove and the left second forming groove, and the pin located on the right side of the electronic component can be formed in the forming cavity formed by the right first forming groove and the right second forming groove. By synchronously matching and evenly acting on the pins of the electronic components, precise forming of both ends of the pins can be achieved at the same time, which can improve the quality of the finished product and manufacturing efficiency.

[0049] Optionally, in some embodiments, a cover 54 is provided on the forming template, and the cover can prevent foreign matter from entering the forming template, thereby ensuring the stability of the operation of the foot cutting machine.

The first support plate is arranged in parallel with the second support plate, the first side plate is arranged in parallel with the second side plate, the first support plate is arranged perpendicularly to the first side plate and the second side plate respectively, and the second support plate is arranged perpendicularly to the first side plate and the second side plate respectively. In addition, the first bottom support plate is located at the pusher block, which can support the push part and ensure the stable movement of the driving device. The first bottom support plate and the second bottom support plate arranged oppositely can enable the two sets of driving devices arranged oppositely to maintain parallel linear movement, thereby ensuring the symmetry and stability of the movement of the forming template.

[0051] Optionally, in some embodiments, the first support plate is provided with a convex edge protruding toward the second support plate, and the second support plate is provided with a convex edge protruding toward the first support plate.

[0052] Optionally, in some embodiments, the embedding groove is located on the convex edge. The embedding groove can be provided on both the first support plate and the second support plate, which can improve the stability of the assembly. Additionally, there are four embedding grooves, which are respectively located on both sides of the first support plate and on both sides of the second support plate.

[0056] Optionally, in some embodiments, the first side plate and the second side plate are respectively provided with side plate openings for the driving device to move and extend out.

Further, as a preferred embodiment of the utility model but not a limitation, the hydraulic cylinder is connected to the hydraulic station, and the hydraulic station is a device that can provide liquid energy and promote the movement of the hydraulic cylinder by applying liquid pressure. Specifically, the hydraulic station is composed of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, an overflow valve and other components, which can provide stable and adjustable pressure and flow.

[0059] like Figures 1 to 9 As shown, the implementation method of this embodiment is as follows:

[0060] A pin cutting machine with pin shaping comprises a frame 1, wherein the frame 1 is provided with an operating table 2, a pin cutting middle plate 3 connected to the operating table 2, the pin cutting middle plate 3 is provided with a first forming groove 30 for the pin to extend into, the operating table 2 is provided with a slide groove 4, a forming template 5 located on the slide groove 4 and capable of extending into the first forming groove 30 to cooperate in pushing and shaping the pin, a cutting knife 6 connected to the lower side of the forming template 5, and a driving device 7 connected to the forming template 5.

[0061] The forming template 5 includes a cutting foot push plate 51, a cutter push plate assembly 52 connected to the driving device 7, and a push bar assembly 53 connected between the cutting foot push plate 51 and the cutter push plate assembly 52. ​​The cutter push plate assembly 52 is provided with a cutter push plate accommodating cavity 520 for accommodating the cutter 6.

[0062] The driving device 7 is provided with a pushing portion 71 , and the cutter pushing plate assembly 52 includes a cutter pushing block 521 connected to the pushing portion 71 , and a cutter pushing plate 522 connected to the cutter pushing block 521 .

[0063] The pushing portion 71 is an axial piston, and the pusher block 521 is sleeved on the outside of the pushing portion 71. The pushing portion 71 converts the power output of the driving device 7 into linear motion to drive the cutter push plate assembly 52 to move linearly. The pusher block 521 and the cutter push plate 522 are connected by fasteners such as screws.

[0064] The push bar assembly 53 includes a push bar connecting seat 531 connected to the cutter push plate 522, a push bar 532 that can be connected to the cutting foot push plate 51, and an elastic assembly 533 located between the push bar connecting seat 531 and the push bar 532. The elastic assembly 533 includes a plurality of connecting shafts 5331 that pass through the push bar connecting seat 531 and are connected to the push bar 532, and an elastic member 5332 that is sleeved on the outside of the connecting shaft 5331 and can abut against the push bar connecting seat 531 and the push bar 532.

[0065] The cutter push plate 522 is provided with a cutter push plate connecting hole 5221 and a fastener 5222, and the cutter 6 is provided with a cutter connecting hole 61. The fastener 5222 passes through the cutter push plate connecting hole 5221 and the cutter connecting hole 61 so that the cutter 6 is connected to the cutter push plate 522.

[0066] The cutter push plate 522 is provided with a second forming groove 5220. The first forming groove 30 and the second forming groove 5220 enclose a forming cavity 8 for pushing and shaping the pin. The horizontal axis of the forming cavity 8 forms an angle α with the horizontal moving direction of the cutter push plate 522, and the angle α is 15 degrees.

[0067] In the prior art, it is necessary to push in four directions, front, back, left, and right, to form the pin. The utility model moves the cutter push plate 522 and cooperates with the pin cutting middle plate 3 to form left and right thrusts in two directions. By setting the angle α, not only the push of the front and back thrusts on the pins is reduced, but also the setting of the angle α can enhance the effect of the pins being pushed and formed while clamping the pins in the left and right directions. As the angle α increases, the direction of the thrust will gradually deviate from the axial direction of the forming cavity 8, and the effect of the bending force will also be enhanced. The pre-forming angle of the pin before shearing can be adjusted according to actual needs to meet the assembly requirements of different electronic products or improve the welding quality.

[0068] The push bar 532 is provided with a connection interface 5321 extending into a position between the cutting foot push plate 51 and the cutting knife 6 .

[0069] The operating table 2 is provided with a support plate 21 for fixing the foot cutting middle plate 3, the support plate 21 encloses the slide groove 4, the support plate 21 is provided with a limiter 213 for limiting the forming template 5, and a foot cutting pressure plate 9 located on the upper side of the foot cutting middle plate 3, the foot cutting pressure plate 9 is provided with a foot cutting pressure plate opening 91 for the pin to extend into. The slide groove 4 enclosed by the support plate 21 is rectangular.

[0070] The cutting foot pressure plate opening 91 is rectangular, and the cutting foot pressure plate opening 91 is tilted. The angle β between the midline between the longest sides and the moving direction of the cutting foot push plate 51 is complementary to the angle α. In this way, the cutting foot pressure plate opening 91 is tilted, which can make the pin move more easily along the predetermined direction when subjected to shearing force, thereby improving the shearing efficiency and quality. The tilted cutting foot pressure plate opening 91 and the corresponding angle β can make the pin move more smoothly during the shearing process, reduce resistance and friction, and thus improve the shearing efficiency and quality.

[0071] The support plate 21 includes a first support plate 2111, a second support plate 2112, a first side plate 2113, and a second side plate 2114. The first support plate 2111 and the second support plate 2112 are arranged opposite to each other, and the first side plate 2113 and the second side plate 2114 are arranged opposite to each other. The slide groove 4 is arranged between the first support plate 2111 and the second support plate 2112. The first support plate 2111 and / or the second support plate 2112 are provided with embedded grooves 2115 for the first side plate 2113 and the second side plate 2114 to extend into respectively. The support plate 21 also includes a first bottom support plate 2116 and a second bottom support plate 2117 respectively connected to the lower side of the cutter push plate assembly 52. ​​The first bottom support plate 2116 and the second bottom support plate 2117 are arranged opposite to each other.

[0072] The driving device 7 includes a hydraulic cylinder 72 connected to the pushing portion 71 and a hydraulic station 73 connected to the hydraulic cylinder 72 .

[0073] The operating table 2 is provided with an operating table opening 20 , a material blocking plate 22 is provided on the side of the operating table opening 20 , and a material receiving hopper 23 is provided on the lower side of the operating table opening 20 .

[0074] The operator first places the electronic components on the operating table 2 so that the pins extend into the first forming groove 30, and drives the forming template 5 to slide in the slide groove 4 through the driving device 7 and cooperate with the first forming groove 30 to push and shape the pins, so that the pins are shaped into the desired shape. When the shaping is completed, the cutter 6 moves with the forming template 5 to cut off the redundant pins extending into the first forming groove 30 and located below the forming template 5. After the cutting is completed, the forming template 5 is reset and drives the cutter 6 away from the first forming groove 30. By cyclically performing the above steps, the electronic components can be shaped and cut for many times. At the same time, there is no need to separate the two steps of pin shaping and cutting, which reduces the material handling and intermediate processing links, shortens the production cycle, and improves production efficiency. At the same time, due to the automation of the entire process, it also reduces the labor intensity of the operator, improves the consistency of work and product quality.

[0075] The elastic member 5332 is sleeved on the outer side of the connecting shaft 5331. When the push-bar connecting seat 531 is forced to move toward the first forming groove 30, the push-bar connecting seat 531 pushes the push-bar 532 through the connecting shaft 5331, thereby driving the cutting foot push plate 51 to abut against the cutting foot middle plate 3. The push-bar connecting seat 531 continues to move toward the first forming groove 30 and abuts against the elastic member 5332. The elastic member 5332 is compressed between the push-bar connecting seat 531 and the push-bar 532. When the external force disappears, the elastic member 5332 can make the push-bar connecting seat 531 rebound to the initial position through its own restoring force, and the connecting shaft 5331 drives the push-bar 532 to reset. When the cutter 6 is reset, the cutter 6 and the push-bar 532 simultaneously drive the cutting foot push plate 51 to move a certain distance through the connecting interface 5321, thereby making the cutting foot push plate 51 separate from the cutting foot middle plate 3.

[0076] The utility model integrates the two steps of pin shaping and cutting into the pin cutting machine, and utilizes the continuity of the shaping and cutting actions to achieve fast and consistent pin shaping and cutting operations, reducing the inconvenience caused by manual operation, simplifying the operation process and improving production efficiency, and effectively reducing the product failure rate and production cost.

[0077] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
