Description

Technical Field

[0001] The invention relates to the technical field of silver contact production, in particular to a continuous cold heading device for special-shaped silver contacts. Background Art

[0002] In electronic appliances, silver contacts usually refer to nodes that make contact and separate when opening and closing. In the prior art, silver contacts are mostly manufactured by cold heading machines, using a punch head to cold press metal materials. Since some electronic appliances require the use of special-shaped silver contacts, multiple cold pressings are often required during the cold pressing process, and different molds need to be replaced each time to ensure that the metal material can form the required shape.

[0003] Chinese patent CN111203507A discloses an automatic continuous cold heading punching machine for special-shaped silver contacts, including a feeding mechanism, a workbench, a first punching device, a second punching device, a feeding mechanism and a demoulding mechanism. However, it ignores the accuracy of mobile transportation during cold heading. Chinese patent CN114632902B discloses an automatic continuous cold heading machine for special-shaped silver contacts, including a support table, a first cold heading bottom die, a second cold heading bottom die, a positioning and conveying device, a synchronous pressing device, a first punch head and a second punch head. This patent realizes the precise feeding of the blank through the positioning and conveying device, thereby improving the accuracy of mobile transportation.

[0004] However, the positioning and conveying device in Chinese patent CN114632902B moves the silver contact blank by a chain conveyor. Although this method is accurate in positioning during low-speed processing, it will result in low processing efficiency. In addition, the setting of the positioning piece for fixing the blank in the positioning and conveying device requires the punch head to pass through the positioning piece and then be inserted into its first cold heading bottom die or the second cold heading bottom die during stamping. This design increases the risk of collision or friction between the punch head and the positioning piece, resulting in increased wear of the punch head during processing, affecting the service life of the punch head. Summary of the invention

[0005] In view of the above problems, a continuous cold heading equipment for special-shaped silver contacts is provided. Through the cooperation of a transverse plate and multiple clamping components, the equipment can complete different processes of multiple silver contact blanks at the same time, significantly improving the production efficiency. The clamping component moves synchronously with the transverse plate to ensure the precise transportation of the silver contact blanks between the molds, avoiding the positioning errors that may occur in traditional chain plate transportation, thereby improving the processing accuracy. The clamping component loosens the workpiece during the stamping process, effectively avoiding direct contact between the punch head and the clamping component, reducing the wear of the punch head and extending the service life of the equipment.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figures 1 to 6 As shown: A continuous and efficient cold heading equipment for special-shaped silver contacts 4, comprising a frame 1, the frame 1 comprising a first mounting plate 2 and a second mounting plate 3 arranged oppositely; a stamping assembly 21 capable of moving along the width direction of the frame 1 is arranged on the first mounting plate 2, and a plurality of stamping heads 211 equidistantly arranged along the length direction of the frame 1 are arranged on the stamping assembly 21; a feed port 31 is arranged on one end of the second mounting plate 3, and molds 32 having the same number and one-to-one correspondence as the stamping heads 211 are arranged on the side of the feed port 31, and the plurality of molds 32 are equidistantly arranged along the length direction of the second mounting plate 3; a transverse plate 33 capable of reciprocating along the length direction of the second mounting plate 3 is arranged on the second mounting plate 3, and the transverse plate 33 is located above the mold 32, and the transverse plate 33 is transmission-connected with the stamping assembly 21; a clamping assembly 331 having the same number and one-to-one correspondence as the mold 32 is arranged on the transverse plate 33, and the plurality of clamping assemblies 331 are equidistantly arranged along the length direction of the transverse plate 33.

[0034] In the initial state, the multiple clamping components 331 on the transverse plate 33 are all in a loose state, wherein the clamping component 331 closest to one end of the feed port 31 is located above the feed port 31, and the remaining clamping components 331 are arranged above the multiple molds 32 respectively. When the processing starts, all the clamping components 331 will perform the clamping action synchronously, respectively clamping the silver contact 4 blanks located at the feed port 31 and each mold 32. Subsequently, the stamping component 21 is started, and the stamping component 21 moves toward the second mounting plate 3 along the width direction of the frame 1, so that the stamping head 211 can approach the mold 32.

[0035] When the punch assembly 21 is started, the transverse plate 33 connected to it also starts to move synchronously, so that the transverse plate 33 moves away from the feed port 31, and the movement of the transverse plate 33 synchronously drives the movement of multiple clamping assemblies 331. When the punch head 211 contacts the silver contact 4, the clamping assembly 331 will release the workpiece, and during the reset of the punch assembly 21, the transverse plate 33 will return to the initial position. With the reset of the transverse plate 33, the silver contact 4 blank fed into the feed port 31 can be clamped by the clamping assembly 331 again, and the silver contacts 4 located in the multiple molds 32 can pop out and be clamped by the multiple clamping assemblies 331, so that the silver contacts 4 can move from the feed port 31 to each mold 32 in turn, thereby realizing the continuous cold heading process of the silver contacts 4.

[0036] Through the synchronous action of multiple clamping components 331, the silver contact 4 blanks in various processing steps can be clamped at the same time, so that each stamping can complete the processing of multiple workpieces in different processes at the same time, which significantly improves the production efficiency. The clamping components 331 move synchronously with the transverse plate 33 to ensure the accurate transportation of the silver contact 4 blanks between the molds 32, avoiding the positioning error that may be caused by traditional chain plate transportation. By loosening the workpiece during the stamping process through the clamping assembly 331, direct contact between the punch head 211 and the clamping assembly 331 is avoided, thereby effectively reducing the wear of the punch head 211 and extending the service life of the equipment, so that the equipment can achieve fully automatic operation of the silver contact 4 blank from feeding to multiple stampings, reduce manual intervention, and improve processing stability and consistency.

[0037] like Figures 1 to 8As shown: the stamping assembly 21 includes a mounting frame 212 which can be slidably arranged on the first mounting plate 2, and two first guide rods 2121 are arranged on the mounting frame 212, and the two first guide rods 2121 are sleeved on the first mounting plate 2 and slidably cooperate with it, and multiple punching heads 211 are installed on the mounting frame 212, and a fixed frame 2122 is arranged in the middle part of the mounting frame 212, and a pulley 2123 which can slide along the height direction is arranged on the fixed frame 2122, and a connecting rod 332 sleeved on the frame 1 is arranged on the end of the transverse plate 33 close to the feed port 31, and the transverse plate 33 is elastically connected to the frame 1, and a fixed plate 333 is arranged on the transverse plate 33, and a guide rail 334 matching the pulley 2123 is arranged on the fixed plate 333.

[0038] The mounting frame 212 is preferably driven by a hydraulic cylinder or a cam. The hydraulic cylinder provides a stable driving force suitable for large torque operations; while the cam drive can achieve precise control, thereby adapting to different types of processing requirements and enhancing the versatility and adaptability of the equipment. By driving the movement of the mounting frame 212, the mounting frame 212 can slide on the first mounting plate 2 through the two first guide rods 2121, thereby driving the multiple punching heads 211 to move synchronously through the mounting frame 212, so that the silver contacts 4 on multiple molds 32 can be processed simultaneously in different processes, thereby improving production efficiency, reducing the waiting time for a single process, and improving the overall production capacity of the equipment. The two first guide rods 2121 slide in cooperation with the first mounting plate 2 to ensure the stability and guiding accuracy of the stamping assembly 21 during movement, avoid processing errors caused by irregular movement or offset, and thus improve the accuracy and consistency of the finished product. By slidingly cooperating the pulley 2123 on the fixed frame 2122 and the guide rail 334 on the transverse plate 33, the transmission process between the transverse plate 33 and the stamping assembly 21 is smoother and more efficient, mechanical friction is reduced, and the operating life and maintenance convenience of the equipment are improved.

[0039] like Figures 3 to 9 As shown: the side of the fixed plate 333 close to the first mounting plate 2 is the driving section 3341 in the guide rail 334 for driving the transverse plate 33 to move, the driving section 3341 is inclined, the side of the fixed plate 333 close to the feed port 31 is the fixed section 3342 in the guide rail 334 for keeping the transverse plate 33 fixed, a section of the fixed section 3342 away from the driving section 3341 is the lifting section 3343 in the guide rail 334 for driving the pulley 2123 to descend in the height direction, a reset section 3344 for resetting the transverse plate 33 is provided at the bottom of the fixed plate 333, and a first elastic member 2124 is provided between the pulley 2123 and the fixed frame 2122.

[0040] Through the action of the first elastic member 2124, the pulley 2123 is always kept at a fixed height on the fixed frame 2122. When the mounting frame 212 moves toward the second mounting plate 3 along the axis direction of the first guide rod 2121, the fixed frame 2122 moves with the mounting frame 212 and drives the pulley 2123 connected thereto to move, so that the pulley 2123 first contacts the driving section 3341 in the guide rail 334. Since the driving section 3341 is arranged at an angle, and the mounting frame 212 can only slide along the axis of the first guide rod 2121, the transverse plate 33 is driven to slide along the length direction of the second mounting plate 3, so that the clamping assembly 331 located on the transverse plate 33 can drive the silver contact 4 to move toward the mold 32 of the next process.

[0041] After the movement is completed, the pulley 2123 will enter the fixed section 3342 in the guide rail 334, at which time the transverse plate 33 stops moving, the clamping assembly 331 releases the workpiece, and the punch head 211 is pressed into the mold 32 to complete the cold heading operation. In the process of the workpiece entering the mold 32, the mounting frame 212 will continue to move for a distance, so that the pulley 2123 can pass through the lifting section 3343 in the guide rail 334, so that the height of the pulley 2123 changes, and the pulley 2123 will descend and squeeze the first elastic member 2124. When the mounting frame 212 finishes moving, the pulley 2123 will slide into the reset section 3344 at the bottom of the fixed plate 333 due to the decrease in height. The transverse plate 33 automatically returns to its initial position due to the lack of support from the pulley 2123 and the elastic connection between the connecting rod 332 and the transverse plate 33 and the frame 1. As the mounting frame 212 is reset, the pulley 2123 is restored to its original height under the action of the first elastic member 2124 , so that it can match with the guide rail 334 again to achieve the reciprocating movement of the transverse plate 33 .

[0042] By setting the inclined guide rail 334, the transverse plate 33 can achieve precise reciprocating movement, ensuring the precise transportation of the silver contacts 4 between working processes and avoiding poor processing due to deviation. By utilizing the reset section 3344 in the guide rail 334 and the transverse plate 33 elastically connected to the frame 1, the transverse plate 33 can automatically return to the initial position after each processing is completed without additional operation, thereby reducing the complexity of operation and improving the degree of automation of the equipment. The design of the pulley 2123 ensures stability when driving the transverse plate 33 to move. In order to improve the stability of the movement of the pulley 2123, an auxiliary plate can also be set beside the fixed plate 333, and the auxiliary plate is provided with a track for assisting the pulley 2123 to descend, thereby further improving the stability of the equipment.

[0043] Through the synchronous movement of the mounting frame 212, the transverse plate 33 and the punch head 211 can synchronously complete the processing of multiple processes on different molds 32, which significantly improves the production efficiency and meets the needs of continuous and efficient production.

[0044] like Figures 1 to 4 and Figures 8 to 10 As shown: the clamping assembly 331 includes two mounting rods 3311, two clamping rods 3312 and two sliding rods 3313. The two mounting rods 3311 are fixedly connected to the transverse plate 33 side by side. The two clamping rods 3312 are respectively sleeved on the two mounting rods 3311, and the two clamping rods 3312 are cross-arranged. The tops of the two clamping rods 3312 are each provided with a slide rail 33121. The transverse plate 33 is provided with a first slide groove 335 extending along its length direction. The two sliding rods 3313 can be relatively slidably arranged on the first slide groove 335, and the ends of the two sliding rods 3313 can be slidably arranged on the slide rails 33121 of the two clamping rods 3312.

[0045] By having the two sliding rods 3313 slide relative to each other in the first sliding groove 335 and by having the sliding rods 3313 slide and cooperate in the sliding rail 33121 of the clamping rod 3312, precise control of the clamping assembly 331 is achieved, so that the farther the distance between the two sliding rods 3313 is, the larger the opening and closing angle of the two clamping rods 3312 is. Thus, the opening and closing angle of the clamping rods 3312 can be precisely adjusted by the relative sliding of the sliding rods 3313, thereby ensuring the stability and reliability of the clamping process and avoiding damage to the workpiece caused by insufficient or excessive clamping force. The two mounting rods 3311 are fixed side by side on the transverse plate 33, providing stable support for the clamping assembly 331. Such a design ensures the stability of the clamping assembly 331 in multiple reciprocating motions, reduces possible loosening or wear during the motion, and extends the service life of the equipment.

[0046] By cross-setting the two clamping rods 3312 in the clamping assembly 331 and connecting them with the sliding rod 3313 through the slide rail 33121, the two clamping rods 3312 can flexibly adjust their opening and closing states. This structure can improve the adaptability of the clamping assembly 331 to the silver contact 4 blank, can effectively clamp workpieces of different sizes and shapes, and increase the versatility of the equipment.

[0047] like Figure 2 , Figures 4 to 10 As shown: a driving frame 336 for driving all clamping components 331 to move synchronously is arranged on the transverse plate 33, and the driving frame 336 can slide along the height direction of the transverse plate 33, and a number of guide components 3361 which are the same as and correspond to the clamping components 331 are arranged on the driving frame 336, and each guide component 3361 includes two guide grooves 33611 which are mirror-symmetrical, and the two guide grooves 33611 are both inclined, and the sliding rod 3313 passes through the first sliding groove 335 and slides with the guide groove 33611.

[0048] The driving frame 336 slides along the height direction of the transverse plate 33, thereby driving the movement of multiple guide components 3361, and driving the two sliding rods 3313 to slide relatively along the first sliding groove 335 through two mirror-symmetrical guide grooves 33611, thereby changing the opening and closing angle of the clamping rod 3312.

[0049] By sliding the drive frame 336 along the height direction of the transverse plate 33, all the clamping components 331 can achieve synchronous movement. The movement of the drive frame 336 drives the synchronous movement of multiple guide components 3361, thereby driving multiple clamping components 331 to clamp or release at the same time, ensuring the coordination and consistency of the processing process, and greatly improving the working efficiency of the equipment. The two mirror-symmetrical guide grooves 33611 in each guide component 3361 enable the sliding rod 3313 to slide relatively smoothly and accurately in the first slide groove 335. Such a design ensures that the control of the opening and closing angle of the clamping rod 3312 is more precise, the clamping process is smooth, and unnecessary shaking or deviation is reduced, thereby improving the processing accuracy. The guide component 3361 and the drive frame 336 are compactly designed. Through reasonable layout, the space occupied by the equipment is smaller, which is conducive to the integrated production line layout. This compact structure allows the equipment to operate efficiently while having higher space utilization. Since the guide groove 33611 is inclined, the opening and closing angle of the clamping rod 3312 can be flexibly adjusted. This design enables the device to adapt to silver contacts 4 of different specifications and shapes, enhances the versatility and adaptability of the device, and can achieve precise clamping in different processes.

[0050] like Figure 2 , Figures 4 to 12 As shown: the top of the driving frame 336 is provided with a second slide groove 3362 extending along its length direction, and the second slide groove 3362 is provided with a slider 33621 that slides with it, and a screw rod 34 that can rotate in a vertical state is provided on the side of the second mounting plate 3 away from the first mounting plate 2, the slider 33621 is sleeved on the screw rod 34 and cooperates with its thread, and the bottom of the screw rod 34 is provided with a rotating drive motor 341 for driving it to rotate.

[0051] By starting the rotary drive motor 341, the output shaft of the rotary drive motor 341 drives the screw rod 34 connected thereto to rotate, and the rotation of the screw rod 34 drives the movement of the slider 33621 threadedly matched therewith. Since the slider 33621 can be slidably arranged on the second slide groove 3362, the movement of the slider 33621 can drive the drive frame 336 to move. At the same time, when the drive frame 336 moves with the transverse plate 33, the driving effect of the screw rod 34 on the drive frame 336 will not be affected, and the precise control of the position of the drive frame 336 is achieved, ensuring the precise execution of the opening and closing action of the clamping assembly 331, so that the drive frame 336 can be adjusted at different height positions according to the set processing requirements. It is ensured that the clamping assembly 331 maintains a precise position and action consistency during the entire processing process, and further improves the precision and consistency of the cold heading processing of the silver contact 4.

[0052] like Figure 2 , Figures 4 to 10 As shown: the first sliding groove 335 of the transverse plate 33 is provided with a protrusion 3351 protruding toward the first mounting plate 2, and the second mounting plate 3 is provided with an avoidance groove 35 matching with the protrusion 3351, and the protrusion 3351 can be slidably arranged in the avoidance groove 35.

[0053] By arranging a protrusion 3351 on the first slide groove 335 of the transverse plate 33, and arranging a matching avoidance groove 35 on the second mounting plate 3, the protrusion 3351 can slide and cooperate in the avoidance groove 35, thereby preventing the transverse plate 33 from interfering with the second mounting plate 3 during movement. This ensures the smoothness of the transverse plate 33 when performing reciprocating movement, improves the stability of the equipment operation, and can also play a positioning role to a certain extent, further improving the accuracy of the transverse plate 33 and the clamping assembly 331 thereon during operation, ensuring that the silver contact 4 blank can be accurately delivered to the processing position, reducing the shaking of the transverse plate 33 when it moves at high speed or frequently, and reducing the processing error caused by the deviation of component movement.

[0054] like Figure 1 , Figure 2 and Figure 6 As shown: a material receiving hopper 11 which can slide along the length direction of the frame 1 is arranged between the bottom of the first mounting plate 2 and the second mounting plate 3.

[0055] Since different numbers of molds 32 are used in the processing of special-shaped silver contacts 4, the unloading positions of the silver contacts 4 are inconsistent. The receiving hopper 11 can slide so that it can be flexibly positioned according to the needs of different processes, facilitating the continuous processing of multiple processes and ensuring that each processing position can receive the processed workpiece in time, thereby avoiding the accumulation or damage of the workpiece after processing. The receiving hopper 11 is located at the bottom of the frame 1 and slides, avoiding interference with the upper stamping or clamping mechanism, ensuring the safety and stability of the equipment during high-speed operation, and reducing the risk of misoperation.

[0056] like Figures 4 to 10 As shown: multiple molds 32 are each provided with an elastic rod 321 for ejecting the workpiece, a push plate 36 for re-pressing the elastic rod 321 is provided at the bottom of the second mounting plate 3, the push plate 36 slides along the height direction of the second mounting plate 3, and the push plate 36 is provided with multiple wedge blocks 361 equidistantly arranged along the length direction of the second mounting plate 3, and the elastic rod 321 is provided with an inclined surface 3211 matching the wedge block 361 at one end close to the push plate 36.

[0057] By setting the elastic rod 321, each time the punch head 211 squeezes the workpiece in the mold 32, the elastic rod 321 can drive the silver contact 4 to pop out under the action of the elastic force. However, after long-term use, the elastic force on the elastic rod 321 may be insufficient or stuck, resulting in the workpiece being unable to pop out. In order to ensure that the silver contact 4 can be stably popped out, a push plate 36 is provided under the multiple elastic rods 321. When the punch head 211 is reset, the push plate 36 will be lifted toward the side of the elastic rod 321 along the height of the second mounting plate 3 until the wedge block 361 above it contacts the inclined surface 3211 of the elastic rod 321. The elastic rod 321 is further squeezed by the force of the wedge block 361, so that the silver contact 4 in the mold 32 can be stably discharged, thereby avoiding the phenomenon of the silver contact 4 being retained in the mold 32.

[0058] By providing the push plate 36 and the wedge block 361, even if the elastic force of the elastic rod 321 weakens after long-term use, the squeezing effect of the wedge block 361 can help the elastic rod 321 to work stably, ensuring that the silver contact 4 can be smoothly ejected in each process after stamping, avoiding the workpiece being stuck in the mold 32 and affecting production, ensuring that each step in the production process is smooth and unobstructed, improving the overall working stability of the equipment, and reducing the possibility of downtime for maintenance.

[0059] like Figures 3 to 9 As shown: an electromagnet 22 is arranged at the bottom of the second mounting plate 3, and a magnetic block 37 is arranged on the push plate 36. When the electromagnet 22 is energized, the magnetic block 37 and the electromagnet 22 are attracted to each other.

[0060] When the electromagnet 22 is energized, an adsorption effect is generated between the magnetic block 37 and the electromagnet 22, so that the push plate 36 rises to squeeze the elastic rod 321, disconnecting the power supply of the electromagnet 22 and releasing the magnetic attraction. It should be noted that the push plate 36 is elastically connected to the bottom of the second mounting plate 3, so that the push plate 36 can restore its initial position after the power supply is disconnected. Through the adsorption effect of the electromagnet 22 and the magnetic block 37, the position of the push plate 36 can be controlled when needed to ensure that it is in a precise working state during the process and avoid process errors caused by position offset.

[0061] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
