Description

Terminal continuous extrusion equipment

Technical Field

The utility model relates to the technical field of stamping dies, in particular to a terminal continuous extrusion molding device.

Background Art

Terminals are the parts that connect batteries to external conductors and are used to connect loads or chargers to the electrical contacts of single or multiple batteries. Terminals are obtained by stamping with a stamping die. Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes, and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size.

The stamping process of battery terminals requires several steps, including terminal loading, terminal and material strip assembly, stamping and forming, and cutting and collecting. Currently, multiple scattered equipment are used to perform the above steps separately. The semi-finished products produced between adjacent equipment need to be transferred manually, resulting in poor production continuity and inability to achieve full-process automatic production of battery terminals.

In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

Referring to FIG. 1 , FIG. 1 is a planar schematic diagram of a terminal continuous extrusion molding device in an embodiment, and the terminal continuous extrusion molding device in this embodiment includes a frame 1, a material strip conveying mechanism 2, a material strip punching mechanism 3, a terminal feeding mechanism 4, a punching mechanism 5, and a cutting and receiving mechanism 6. The material strip conveying mechanism 2, the material strip punching mechanism 3, the terminal feeding mechanism 4, the punching mechanism 5, and the cutting and receiving mechanism 6 are respectively arranged on the frame 1. The material strip 100 on the material strip conveying mechanism 2 passes through the material strip punching mechanism 3, the terminal feeding mechanism 4, the punching mechanism 5, and the cutting and receiving mechanism 6 in sequence. The punching end of the material strip punching mechanism 3 faces the material strip on the material strip conveying mechanism 2, and the material strip punching mechanism 3 punches the material strip 100 and forms a terminal hole 101. The terminal feeding mechanism 4 feeds the terminal into the terminal hole 101 and forms a terminal unit on the material strip 100. The punching mechanism 5 punches the terminal unit. The cutting and collecting mechanism 6 cuts the material strip 100 and separates and collects the terminal units.

Referring to FIG. 2 , FIG. 2 is a schematic diagram of the structure of the material strip and the terminal hole in the embodiment. The terminal continuous extrusion molding equipment in this embodiment is placed on the floor of the factory for use, and is used to produce a kind of automobile battery terminal. Specifically, the material strip punching mechanism 3 first punches a plurality of terminal holes 101 on the material strip 100, and the terminal feeding mechanism 4 feeds the terminal into the terminal hole 101 and forms a plurality of terminal units. The stamping mechanism 5 stamps the terminal unit so that the terminal is firmly embedded in the terminal hole 101 and is stamped into a preset shape. The cutting and collecting mechanism 6 cuts and separates the stamped terminal unit, and collects the material to obtain the automobile battery terminal. In this way, this embodiment can realize the full process of automated production of automobile battery terminals, with high production continuity, saving a lot of labor costs, and improving production efficiency and product quality. Specifically, the terminal in this embodiment is a cylindrical stainless steel cylinder, the material strip 100 is a long strip of stainless steel plate, and the aperture of the terminal hole 101 is slightly smaller than the diameter of the terminal. The material strip conveying mechanism 2 is an existing linear conveying module, which linearly conveys the material strip and allows the material strip to pass through the material strip punching mechanism 3, the terminal feeding mechanism 4, the punching mechanism 5 and the cutting and receiving mechanism 6 in sequence. The upper mold assembly 51 is raised and lowered by a cylinder drive. The material strip punching mechanism 3 is an existing punching module, which performs a punching operation on the material strip and punches a plurality of terminal holes 101 on the material strip.

Referring to Figures 3-4, Figure 3 is a schematic diagram of the structure of the terminal continuous extrusion molding equipment in the embodiment, and Figure 4 is an enlarged view of part A in Figure 3. Preferably, the stamping mechanism 5 includes an upper die assembly 51 and a lower die assembly 52. The upper die assembly 51 and the lower die assembly 52 are arranged in parallel and spaced apart. The upper die assembly 51 is provided with a punching piece 511, and the lower die assembly 52 is provided with a punching piece 521 at a position corresponding to the punching piece 511. The lower die assembly 52 is arranged on the frame 1, and the material strip conveying mechanism 2 conveys the material strip of the loaded terminal through the upper die assembly 51 and the lower die assembly 52. The upper die assembly 51 is movably arranged on the frame 1. The upper die assembly 51 gradually approaches the lower die assembly 52, driving the punching piece 511 to approach the punching piece 521, and the punching piece 511 presses the terminal unit into the punching piece 521 for stamping molding. In specific application, the upper die assembly 51 is a double-layer structure, specifically a pressing plate and a bearing plate, between which a spring and a guide column are connected, the pressing plate is located above the lower die assembly 52, and the bearing plate is located above the pressing plate, one end of the punch 511 is connected to the bearing plate, and the other end passes through the pressing plate and faces the punching member 521 on the lower die assembly 52. During stamping, the pressing plate and the bearing plate descend synchronously, and the pressing plate gradually approaches the lower die assembly 52 until the material strip is pressed between the pressing plate and the lower die assembly 52. Through the setting of the spring and the guide column, the bearing plate continues to descend at this time, that is, the punch 511 continues to descend to press the terminal on the punching member 521. Since the pressure applied by the punch 511 is relatively large, and the terminal is made of stainless steel and has a certain ductility, the terminal is extended synchronously when it is pressed on the punching member 521, that is, the shape of the terminal changes synchronously, and is punched into the shape of the punching member 521 by the punch 511. At the same time, the terminal is stamped and stretched, which also makes the terminal more firmly pressed into the terminal hole 101. It should be noted that the material strip at the edge of the terminal hole 101 is also synchronously pressed into the punching member 521 for stamping, that is, the stamping mechanism 5 is used to stamp the terminal unit. Specifically, the punch member 511 includes a punch and a nitrogen spring, and the two ends of the nitrogen spring are respectively connected to the punch and the supporting plate. Since the interaction force between the punch and the terminal unit is large during the stamping process, the setting of the nitrogen spring can provide a certain buffering effect, which ensures that the punch has sufficient pressing force while avoiding damage to the punch and improving the stability of the equipment.

Referring again to FIGS. 3-4 , preferably, the punching member 521 includes a forming hole 5211 and a lifting and demolding portion 5212. The forming hole 5211 is provided in the lower die assembly 52 and is directly opposite to the punch member 511. The lifting and demolding portion 5212 is provided at the bottom of the forming hole 5211. The punch member 511 presses the terminal unit into the forming hole 5211 for stamping, and the lifting and demolding portion 5212 lifts the formed terminal unit and separates it from the forming hole 5211. In specific applications, the shape of the forming hole 5211 is the shape that the terminal unit needs to be stamped into. After the terminal unit is pressed into the forming hole 5211 by the punch, the terminal unit is still continuously stamped by the punch. Since the metal has ductility, the terminal unit is deformed and closely adheres to the inside of the forming hole 5211, thereby extending into the shape of the forming hole 5211. After the terminal unit is stamped, it is tightly attached to the forming hole 5211. The lifting and demolding part 5212 is provided to support the terminal unit during the stamping process. After the stamping is completed, the lifting and demolding part 5212 pushes the terminal unit upward to move it upward, thereby separating the terminal unit from the forming hole 5211 and demolding it, so that the material belt conveying mechanism 2 can continue to convey the terminal unit through the material belt to the next step. Specifically, the lifting and demolding part 5212 is a nitrogen spring, which is provided on the lower mold assembly 52.

Referring again to Figures 3-4, preferably, the number of punching parts 511 and punching parts 521 are both multiple, and along the moving direction of the material strip, multiple punching parts 521 are sequentially arranged at intervals on the lower die assembly 52, and multiple punching parts 511 are sequentially arranged at intervals on the upper die assembly 51 and respectively face the multiple punching parts 521. In specific applications, the stress of the terminal unit is relatively large during stamping, and multiple stamping forming of the terminal unit can be achieved by setting multiple punching parts 511 and multiple punching parts 521. Along the moving direction of the material strip, the shapes of the multiple forming holes 5211 are gradually changed, so that the terminal unit is gradually stamped, so that the terminal unit only undergoes slight deformation each time it is stamped, effectively reducing the stress of the terminal unit during a single stamping, avoiding damage to the terminal unit due to excessive stress, and improving the stamping quality of the product. Furthermore, the material belt conveying mechanism 2 conveys the material belt for linear movement and makes the material belt pass through the material belt punching mechanism 3, the terminal feeding mechanism 4, the stamping mechanism 5 and the cutting and collecting mechanism 6 in sequence, that is, a production line integrating the whole process of material belt punching, terminal feeding, stamping forming and cutting and collecting is formed. The material belt conveying mechanism 2 in this embodiment is not continuously conveyed in actual use, but conveys a section of the material belt forward at intervals, that is, conveys the material belt forward by one work station, which is equivalent to forming multiple work stations on the material belt in sequence, and the multiple work stations pass through the material belt punching mechanism 3, the terminal feeding mechanism 4, the stamping mechanism 5 and the cutting and collecting mechanism 6 in sequence to perform different processes. The interval time is specifically the time for the stamping mechanism 5 to perform a stamping action, that is, after the stamping actions of the stamping mechanism 5 are completed, the material strip conveying mechanism 2 synchronously conveys the material strip forward one workstation, and the stamping mechanism 5 performs the stamping action again, and this is repeated. The material strip punching mechanism 3 performs a punching process on the material strip and forms a terminal hole 101 on the material strip, and then the material strip advances one workstation, and the material strip punching mechanism 3 continues to perform the punching process on the material strip, and the area of the material strip where the terminal hole 101 has been punched advances to the terminal loading mechanism 4 to receive the terminal loading. The production continuity of this embodiment is high and the degree of automation is high.

Referring to FIGS. 5-6 , FIG. 5 is a schematic diagram of the structure when the upper mold assembly and the lower mold assembly are opened and closed in the embodiment, and FIG. 6 is an enlarged view of part B in FIG. 5 . Preferably, the terminal feeding mechanism 4 includes a loading assembly 41, a material transfer assembly 42 and a moving assembly 43. The loading assembly 41 is arranged adjacent to the material transfer assembly 42, the material transfer assembly 42 is movably arranged on the lower mold assembly 52, and the moving assembly 43 is connected to the material transfer assembly 42. The material transfer assembly 42 receives the terminal from the loading assembly 41, and the moving assembly 43 moves the material transfer assembly 42 to the bottom of the terminal hole 101. The terminal is directly opposite to the terminal hole 101. The upper mold assembly 51 is provided with a through hole 512 corresponding to the terminal hole 101. The upper mold assembly 51 gradually approaches the lower mold assembly 52, and the upper mold assembly 51 pushes the material strip close to the lower mold assembly 52, and the terminal is pressed into the terminal hole 101. In specific application, the loading component 41 is an existing vibration disk, and the terminals are arranged in sequence on the vibration disk. The material transfer component 42 is a material transfer box, which is movably arranged on the lower mold component 52. The movable connection method is the existing slide rail and slider to achieve sliding, which will not be repeated here. It should be noted that the material transfer component 42 moves back and forth between the discharge port of the loading component 41 and the bottom of the material belt 100, and its movement trajectory is perpendicular to the transmission direction of the material belt 100. When the material transfer component 42 moves to the bottom of the material belt 100, the terminal located in the material transfer bearing position is directly opposite to the terminal hole 101 of the material belt 100, and the upper mold component 51 and the lower mold component 52 are fitted to press the material belt 100 between the upper mold component 51 and the lower mold component 52. After the terminal passes through the terminal hole 100, it is accommodated in the through hole 513, so that the terminal is loaded into the terminal hole 101. In this way, the automatic loading of the terminal can be realized, and the continuity of production can be improved. Specifically, there are two terminal feeding mechanisms 4, which are respectively arranged on both sides of the material belt conveying mechanism 2 perpendicular to the moving direction of the material belt, and the two terminal feeding mechanisms 4 simultaneously feed the terminals to the terminal holes 101. The material belt punching mechanism 3 in this embodiment has two punching blades arranged side by side, and the material belt punching mechanism 3 punches two rows of terminal holes 101 arranged side by side on the material belt. The two terminal feeding mechanisms 4 are respectively arranged on both sides of the material belt conveying mechanism 2, one of which is responsible for feeding the terminals to one row of terminal holes 101 on the material belt 100, and the other terminal feeding mechanism 4 is responsible for feeding the terminals to the other row of terminal holes 101 on the material belt 100, so that double-station feeding can be achieved, and twice the products can be produced in the same time, thereby improving production efficiency. At the same time, the material strip punching mechanism 3 is arranged on the upper mold assembly 51. When the upper mold assembly 51 descends to perform the punching process, the material strip punching mechanism 3 descends synchronously to perform the punching process on the material strip, that is, the stamping process and the punching process are performed simultaneously at different stations to achieve continuous and uninterrupted production. The feeding principle and process of the two terminal feeding mechanisms 4 are the same. The only difference is that the terminal feeding is realized in two different directions from both sides of the material strip conveying mechanism 3. In this embodiment, only one of the terminal feeding mechanisms 4 is described, and the other terminal feeding mechanism 4 is a synchronous mirror process, which will not be repeated here.

Referring again to FIGS. 5-6 , preferably, the moving assembly 43 includes an elastic member 431 and a push member 432, wherein the elastic member 431 is connected to the material transfer assembly 42, and the push member 432 is disposed on the upper mold assembly 51. The push member 432 is provided with a first guide slope 4321 at one end facing the material transfer assembly 42, and a second guide slope 421 is correspondingly provided at one end of the material transfer assembly 42 facing the push member 432, and the first guide slope 4321 and the second guide slope 421 are staggered. In specific applications, the elastic member 431 is a tension spring, one end of which is connected to the frame 1, and the other end is connected to the material transfer assembly 42. The push member 432 is a push column, which is disposed on the upper mold assembly 51. After the material transfer component 42 is connected to a terminal from the vibration plate, the upper mold assembly 51 descends, driving the pushing member 432 to descend synchronously. When the first guide slope 4321 on the pushing member 432 contacts the second guide slope 421 on the material transfer component 42, as the upper mold assembly 51 and the pushing member 432 further descend, the first guide slope 4321 and the second guide slope 421 come into staggered contact. Since the pushing member 432 is fixed to the upper mold assembly 51 and the material transfer component 42 is movably arranged, the material transfer component 42 is pushed by the pushing member 432, thereby driving the terminal carried thereon to move to the bottom position of the terminal hole 101. As the upper mold assembly 51 further descends, the upper mold assembly 51 gradually presses the terminal into the terminal hole 101. After the terminal is loaded to the terminal hole 101, the upper mold assembly 51 rises and resets, driving the pusher 432 to rise synchronously. Due to the elastic force of the elastic member 431, the material transfer assembly 42 is pulled back to the original position to continue to receive the terminal from the vibration plate and repeat the loading process. In this way, the material transfer assembly 42 can be used to transfer the terminal back and forth without setting a cylinder, saving assembly costs and simplifying the equipment structure. At the same time, relying only on the mechanical structure to make the material transfer assembly 42 move back and forth also avoids the equipment from not being able to operate normally due to failure of components such as the cylinder, thereby improving the stability of this embodiment. Specifically, the upper mold assembly 51 is provided with a groove corresponding to the position of the material transfer assembly 42, so as to avoid the upper mold assembly 51 being pressed against the material transfer assembly 42 to cause damage to the equipment.

Referring again to Figures 5-6, preferably, the terminal feeding mechanism 4 also includes a feeding punch assembly 44, and the feeding punch assembly 44 is arranged on the upper die assembly 51, and the feeding punch assembly 44 is directly opposite to the terminal at the discharge port of the loading assembly 41. The material transfer assembly 42 has a material transfer bearing position, and a spring clip is arranged in the material transfer bearing position. The upper die assembly 51 drives the feeding punch assembly 44 to approach the material transfer assembly 42, and the feeding punch assembly 44 pushes the terminal on the material transfer assembly 42 through the spring clip and presses it into the material transfer bearing position. In specific applications, the structure and principle of the feeding punch assembly 44 are similar to those of the punch component 511, and will not be repeated here. The descent of the upper die assembly 51 drives the punch to descend synchronously, and the punch presses the terminal of the discharge port of the loading assembly 41 into the material transfer bearing position of the material transfer assembly 42. At the same time, a spring clip is provided in the material transfer bearing position to ensure that the terminal can be stably carried in the material transfer assembly 42. In addition, since the terminals in the vibration disk need to be punched by the punch before they can be discharged, the terminals can be discharged one by one and by punching, so as to avoid the terminals accidentally falling from the vibration disk to the lower die assembly 52 to cause damage to the equipment, thereby improving the stability and safety of the equipment. Furthermore, the distance between the material transfer assembly 42 and the pusher 432 is greater than the distance between the loading punch assembly 44 and the discharge port of the loading assembly 41. In this way, when the upper die assembly 51 descends, the loading punch assembly 44 reaches the discharge port of the loading assembly 41 first, and at this time, the pusher 432 has not reached the material transfer assembly 42, that is, at this time, the material transfer assembly 42 is located at the bottom of the discharge port of the loading assembly 41. The loading punch assembly 44 presses the terminal on the loading assembly 41 into the material transfer bearing position of the material transfer assembly 42. As the upper mold assembly 51 further descends, the pushing member 432 contacts the material transfer assembly 42, and the pushing member 432 pushes the material transfer assembly 42 to move, thereby transferring the terminal to the bottom position of the terminal hole 101, further improving the degree of automation and production continuity of this embodiment.

Referring again to Figures 5-6, preferably, the terminal feeding mechanism 4 also includes a preliminary stamping assembly 45, and the preliminary stamping assembly 45 includes a demoulding member 451 and a preliminary stamping member 452. The demoulding member 451 is arranged on the lower mold assembly 52 and is directly opposite to the through hole 512. The preliminary stamping member 452 is movably arranged in the through hole 512, and the material transfer bearing position is the preliminary forming hole. The material transfer assembly 42 transfers the terminal to the bottom of the terminal hole 101, and the preliminary stamping member 452 presses the terminal unit into the preliminary forming hole for preliminary stamping and forming, and the demoulding member 451 lifts and pushes the terminal unit to separate from the material transfer assembly 42. In specific applications, the structure and principle of the preliminary stamping member 452 are similar to those of the punch member 511, and the structure and principle of the demoulding member 451 are similar to those of the lifting demoulding part 5212, which will not be repeated here. The material transfer assembly 42 moves to the bottom of the material strip so that the terminal is aligned with the terminal hole 101. The upper mold assembly 51 descends, driving the preliminary stamping part 452 to descend synchronously. The upper mold assembly 51 contacts the material strip first and presses the terminal into the terminal hole 101 on the material strip to form a terminal unit. The preliminary stamping part 452 presses the terminal unit into the material transfer bearing position for preliminary stamping and forming. In this way, the terminal can be pressed into the terminal hole 101 more firmly. At the same time, the first stamping and forming is performed when loading the material. When the subsequent stamping mechanism 5 performs multiple progressive continuous stampings, one less workstation can be set up, saving stamping time and improving production efficiency. Specifically, the distance between the preliminary stamping part 452 and the material transfer component 42 is greater than the distance between the material transfer component 42 and the pushing member 432. In this way, during the one-time descent of the upper mold component 51, the material transfer component 42 first receives the terminal from the loading component 41, and then transfers the terminal to the bottom of the terminal hole 101. Finally, the preliminary stamping part 452 performs preliminary stamping and forming on the terminal unit, which effectively improves the production efficiency and the continuity of equipment operation.

Referring again to FIGS. 5-6 , preferably, the lower mold assembly 52 includes a first lower mold 522, a second lower mold 523 and a movable column 524. The first lower mold 522 is arranged on the frame 1. A telescopic connector is arranged at the bottom of the first lower mold 522. The second lower mold 523 is connected to an end of the telescopic connector away from the first lower mold 522. One end of the movable column 524 is arranged on the second lower mold 523, and the other end passes through the first lower mold 522. The upper mold assembly 51 is provided with a top column 513 at a position corresponding to the movable column 524. The punching member 521 is arranged on the first lower mold 522, and the demoulding member 451 is arranged on the second lower mold 523. In specific applications, the telescopic connector is a spring. It enables the first lower mold 522 and the second lower mold 523 to achieve telescopic connection. The upper mold assembly 51 descends, driving the ejector column 513 to descend synchronously. The ejector column 513 pushes the movable column 524 to descend synchronously. The descent of the movable column 524 drives the second lower mold 523 to descend synchronously. The first lower mold 522 is fixed to the frame 1, that is, the second lower mold 523 is away from the first lower mold 522. The descent of the second lower mold 523 drives the demolding member 451 to descend synchronously, and then the material transfer assembly 42 moves to the top of the demolding member 451. Specifically, an ejector pin 422 is provided at the bottom of the preliminary forming hole. The ejector pin 422 is movably provided in the preliminary forming hole. When the material transfer assembly 42 moves to the top of the demolding member 451, the demolding member 451 contacts the bottom of the ejector pin 422. The preliminary stamping part 452 preliminarily stamps the terminal unit into the preliminary forming hole, and the nitrogen spring of the demolding part 451 is squeezed and deformed. After the preliminary stamping is completed, the upper mold assembly 51 rises and resets, and the impact of the preliminary stamping part 452 on the terminal unit disappears. The nitrogen spring of the demolding part 451 recovers, pushing the ejector pin 422 to rise, and the ejector pin 422 pushes the terminal unit to rise and separate from the preliminary forming hole to achieve demolding. As the upper mold assembly 51 rises further, the material transfer assembly 42 returns to the loading assembly 41 to continue to receive the terminal, and the demolding part 451 rises and resets. Specifically, the distance between the ejector column 513 and the movable column 524 is smaller than the distance between the pusher 432 and the material transfer assembly 42. In this way, when the upper mold assembly 51 descends, the ejector column 513 and the movable column 524 come into contact first, so that the demolding part 451 descends first, which facilitates the subsequent movement of the material transfer assembly 42 above it.

Referring again to Figures 1-6, preferably, the cutting and receiving mechanism 6 includes a cutting component and a receiving component, the cutting component is arranged on the upper mold component 51, and the receiving component is arranged on the lower mold component 52. The cutting end of the cutting component faces the material strip on the material strip conveying mechanism 2, and is directly opposite to the receiving port of the receiving component. In specific applications, the cutting component is an existing material strip cutter. The receiving component includes a receiving pipe and a receiving tray connected to the receiving pipe, and the receiving pipe is passed through the lower mold component 52. The descent of the upper mold component 51 drives the cutting component to descend synchronously to cut the material strip, that is, to cut and separate the terminal unit from the material strip, and the cut terminal unit falls from the receiving pipe into the receiving tray for collection. It should be noted that due to the large stress of stainless steel, the cutting assembly of this embodiment has four cutting openings, two of which are located at the same cutting station, and the other two are located at the next cutting station. At the previous cutting station, the cutting assembly performs preliminary cutting and separation on the terminal unit, thins the connection between the terminal unit and the material strip, and the cutting assembly at the next cutting station cuts and separates the terminal unit as a whole. This effectively avoids the situation where warping or cracking occurs on the four sides of the terminal unit due to one-time cutting, thereby improving product quality. Specifically, the material strip punching mechanism 3, the punch part 511, the pushing part 432, the loading punch assembly 44, the preliminary stamping part 452 and the cutting assembly of the present embodiment are all arranged on the upper mold assembly 51, that is, during one descent process of the upper mold assembly 51, the material strip punching mechanism 3, the terminal loading mechanism 4, the stamping mechanism 5 and the cutting and receiving mechanism 6 respectively perform the material strip punching, terminal loading, terminal unit stamping and terminal unit cutting and receiving processes at different stations, thereby improving the production efficiency and the continuity of the equipment. When the upper mold assembly 51 rises and resets, the material strip conveying mechanism 2 linearly conveys the material strip a distance of a station, and the lower mold assembly 52 continues to repeat the descending action, thereby continuously and repeatedly realizing the continuous stamping die process.

Referring to FIGS. 7-8 , FIG. 7 is a schematic diagram of the structure of the upper die assembly and the lower die assembly when they are pressed together in the embodiment, and FIG. 8 is an enlarged view of part C in FIG. 7 , wherein the specific working process of the terminal feeding mechanism 4 is as follows: the upper die assembly 51 descends, driving the pusher 432, the top column 513 and the feeding punch assembly 44 to descend synchronously. During the descent process, the feeding punch assembly 44 first contacts the terminal on the loading assembly 41, and presses the terminal into the preliminary forming hole of the material transfer assembly 42. Then the top column 513 contacts the movable column 524, driving the movable column 524 to descend, thereby driving the second lower die 523 and the demolding member 451 to descend synchronously. After that, the pusher 432 contacts the material transfer assembly 42, pushes the material transfer assembly 42 to drive the terminal to move to the bottom of the terminal hole 101, at which time the demoulding member 451 is located at the bottom of the preliminary forming hole. As the upper mold assembly 51 further descends, the upper mold assembly 51 presses the material strip to press the terminal into the terminal hole 101 to form a terminal unit, and the preliminary stamping member 452 stamps the terminal unit into the preliminary forming hole for preliminary stamping. The upper mold assembly 51 rises and resets, the preliminary stamping member 452 separates from the terminal unit, and the demoulding member 451 pushes the terminal unit from the bottom through the ejector pin 422 to rise and separate from the preliminary forming hole for demoulding. The pusher 432 separates from the material transfer assembly 42, the elastic member 431 pulls the material transfer assembly 42 to reset, and the demoulding member 451 rises and resets. The material strip conveying mechanism 2 moves the material strip by one station, so that the terminal unit after preliminary forming is synchronously moved to the next station, and at the same time, another terminal hole 101 is moved between the preliminary stamping member 452 and the demoulding member 451.

In summary, the material belt conveying mechanism 2 conveys the material belt and makes it pass through the material belt punching mechanism 3, the terminal feeding mechanism 4, the stamping mechanism 5 and the cutting and collecting mechanism 6 in sequence. The material belt punching mechanism 3 first punches holes on the material belt to form a plurality of terminal holes 101, the terminal feeding mechanism 4 feeds the terminal into the terminal hole 101 and forms a plurality of terminal units, the stamping mechanism 5 stamps the terminal unit so that the terminal is firmly embedded in the terminal hole 101 and is stamped into a preset shape, and the cutting and collecting mechanism 6 cuts and separates the stamped terminal unit, and collects the material to obtain the automobile battery terminal. In this way, this embodiment can realize the full process automated production of automobile battery terminals, with high production continuity, saving a lot of labor costs, and improving production efficiency and product quality.

The above is only the implementation mode of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
