Description

[0002] Terminals serve to provide wiring connections and secure fasteners during the assembly process of electrical products (such as surge arresters). See attached... Figure 1 As shown, the terminal is initially a solid rod, which is then stretched to form a pre-processed rod. At this stage, one end of the pre-processed rod is solid, while the other end has an open cavity. The two parts have different diameters; the cavity end has a larger diameter than the solid part, creating a stepped structure (one end larger, one end smaller). Next, chamfering is performed to form a semi-finished product. The semi-finished product is then forged, pressing the solid part. Finally, the forged area is cut and punched to form the terminal's connecting portion. This connecting portion is used to form an electrical connection with an external circuit, while the cavity end is used to form an electrical connection with a cable.

[0046] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0047] Example 1

[0048] This embodiment provides a linked terminal production line, as shown in the attached figure. Figures 1-8 As shown, it includes:

[0049] The stretching device 11 includes a first stamping member 111, which stretches a solid bar stock. Specifically, this stretching operation refers to stamping stretching, a stretching effect produced by stamping, forming a bar stock processed in one operation. At this point, one end of the processed bar stock is a solid structure, while the other end has an open cavity. The two parts have different diameters; the diameter of the cavity end is larger than the diameter of the solid part, forming a stepped structure (one end larger, one end smaller). Furthermore, the weight of the solid part is greater than the weight of the other end (one end heavier, one end lighter). In this embodiment, the solid bar stock is specifically a solid cylindrical structure and is made of a conductive metallic material, specifically the raw material for making terminals, such as copper. Further, the first stamping member 111 cooperates with a cylinder or hydraulic cylinder to achieve the stamping stretching effect.

[0050] The first lifting device 12 transports solid bar stock to the stretching device 11. The lower end of the first lifting device 12 is located close to the horizontal ground, allowing operators to easily place the solid bar stock into it. The first lifting device 12 then lifts the solid bar stock from bottom to top, transporting it to the stretching device 11. The stretching device 11 is located at the top of the first stretching device 11. Operators can use a shovel or forklift to drop the solid bar stock into the lower end of the first lifting device 12.

[0051] The rounding device 13 includes a chamfering component 131, which chamfers the bar stock processed in one step to form a semi-finished product. Specifically, the chamfering refers to chamfering the outer surface of the stepped connection. Furthermore, the chamfering component 131 cooperates with a motor or cylinder to drive the chamfering component to work; or the chamfering component 131 is in a stationary state, and the motor or cylinder drives the bar stock processed in one step to rotate, thus forming the chamfering process.

[0052] The integrated device 14 includes a forging chamber 141 and a trimming chamber 142. The forging chamber 141 is used for forging, and the trimming chamber 142 is used for trimming and punching. Here, trimming and punching are the same step. Trimming refers to removing the edge area of ​​the forged semi-finished product, and punching is punching a hole in the center of the forging area. The semi-finished product is first placed in the forging chamber 141 and then moved to the trimming chamber 142. The integrated device 14 performs forging, trimming, and punching on the chamfered solid bar stock; here, the forging, trimming, and punching operations are all performed on the solid part of the semi-finished product.

[0053] The second lifting device 15 transports the semi-finished product. One end of the second lifting device 15 is connected to the circular opening device 13, and the other end extends towards the integrated device 14. The semi-finished product is lifted to a certain height by the second lifting device 15. The lifting height can be adjusted according to actual needs. After processing, the semi-finished product enters the second lifting device 15 and is moved by it.

[0054] The third lifting device 16 has one end located vertically below the end of the second lifting device 15. The semi-finished product is lifted by the second lifting device 15 and then falls to one end of the third lifting device 16 at the highest point. The other end of the third lifting device 16 is connected to the integrated device 14, which transports the semi-finished product to the integrated device 14 for forging, trimming, and punching, thereby realizing the processing of the entire terminal.

[0055] The head-identifying input device 17 includes a head-identifying component 171. The head-identifying component 171 determines the diameter or weight of the semi-finished product. Since the diameters (and weights) of the two ends of the semi-finished product are different, the head-identifying component 171 determines the orientation of the semi-finished product, i.e., which end is the solid structure, forming an evenly spaced arrangement, thus ensuring that the semi-finished products conveyed to the integrated device 14 all face the same direction. Those skilled in the art can distinguish between the two ends based on their different diameters or weights. The diameter can be measured by infrared measurement or other methods, and the weight can be detected by drop detection or other methods. Those skilled in the art can also use probe detection in conjunction with the pushing structure to push the solid bar back into the third lifting device 16 when it is not placed in the prescribed orientation; or they can use a mechanical structure to determine if the orientation is reversed, causing it to fall back into the third lifting device 16. Alternatively, subsequent detection devices can be used to control the rotation of the clamping device, also achieving the effect of reversing the direction.

[0056] The first lifting device 12 makes it easy for operators to load solid bar stock without having to lift them, reducing workload. The second lifting device 15 and the third lifting device 16 work together to create physical deceleration, meeting the processing frequency of each process, thus ensuring that the entire production line will not be blocked or short of material during operation, improving efficiency. Moreover, the lifting can shorten the length of the entire production line, reducing the space occupied by the production line in the workshop. The setting of the head piece 171 creates a differentiation effect, ensuring that the semi-finished products entering the integrated device 14 are all oriented in the same direction.

[0057] Specifically, as shown in the attached document Figure 7As shown, the head component 171 has a through hole 172. The through hole 172 has a middle region 1721 and end regions 1722 located at both ends of the middle region 1721. The width of the end regions 1722 is smaller than the width of the middle region 1721, and the length of the middle region 1721 is greater than the length of the end regions 1722, forming a structure that is larger in the middle and smaller at both ends. When the semi-finished product moves above the through hole 172, the semi-finished product is moved horizontally above the through hole 172 as a whole. For example, if the left end of the semi-finished product is a solid part, the left end of the semi-finished product is located in the left end region 1722, and the right end of the semi-finished product abuts against the top surface of the right end region 1722. At this time, due to the effect of gravity, the left end of the semi-finished product falls down first along with the right end of the semi-finished product, and the semi-finished product will also rotate. The right end of the semi-finished product will also enter the end region 1722, achieving an effect of orientation differentiation. Conversely, for example, if the right end of the semi-finished product is solid and located in the right end region 1722, and the left end of the semi-finished product abuts against the top surface of the left end region 1722, then due to gravity, the right end of the semi-finished product will fall first along with the left end, causing the semi-finished product to rotate. The left end will then enter the end region 1722, achieving an orientation distinction. In this case, the solid part will fall first along with the other end, ensuring that all semi-finished products entering the integrated device 14 have the solid part in front and the rest behind. The lengths of the middle region 1721 and the end region 1722 can be adjusted according to actual needs. Those skilled in the art can set the corresponding parameters based on the actual length of the semi-finished product through calculation and multiple adjustments. Alternatively, the orientation of the two ends can be distinguished by infrared sensing or by a pin testing structure, or by a structure that detects the orientation of chopsticks (i.e., a protrusion is set in the center of the inner wall of the through hole 172; when the semi-finished product falls, the direction can also be determined based on weight). In this embodiment, the semi-finished product can be driven to move by a conveyor belt or a vibration structure, and then pushed to the top of the head 171 by a horizontally driven motor, cylinder or hydraulic cylinder, so that the semi-finished product fits into the through hole 172.

[0058] Specifically, as shown in the attached document Figures 2-6 As shown, it also includes a first conduit 18, which connects the head input device 17 and the integrated device 14. Semi-finished products falling from the head component 171 enter the integrated device 14 through the first conduit 18, forming an evenly spaced arrangement so that the semi-finished products face the same direction, i.e., the solid end faces down. The first conduit 18 serves as a transport and guide, allowing the semi-finished products to accurately enter the next process. In this embodiment, the first conduit 18 is a transparent tubular structure.

[0059] Specifically, as shown in the attached document Figures 2-6 , Figure 8As shown, the integrated device 14 includes a first slider 143, a first drive source 144 cooperating with the first slider 143, and a second stamping part 145. The first drive source 144 drives the first slider 143 to slide, causing the first slider 143 to slide relative to the second stamping part 145. The second stamping part 145 includes a first cavity, a second cavity, and a third cavity, with the second cavity located between the first and third cavities. In a first state, the first slider 143 cooperates with the first cavity to form a trimming cavity 142, and the first slider 143 cooperates with the second cavity to form a forging cavity 141. In a second state, the first slider 143 cooperates with the third cavity to form the trimming cavity 142, and the first slider 143 cooperates with the second cavity to form the forging cavity 141. Through the reciprocating motion of the first slider 143, processing at different positions is achieved, improving processing efficiency. The middle position here is the loading area, i.e., loading at one end. During loading, the processed terminal is pushed out from the other end, realizing synchronous loading and unloading operations, further improving processing efficiency. In other words, the semi-finished product enters the integrated device 14 through the first conduit 18, and is pushed into the forging chamber 141, which is the middle position, by a cylinder or oil cylinder. Then, the second stamping part 145 is pressed down to form the solid part of the semi-finished product through forging. Then, the first drive source 144 drives the first slider 143 to move to the right, so that the forged semi-finished product moves to the trimming chamber 142 on the right side. At the same time, the semi-finished product is loaded again in the middle position, and the second stamping part 145 is pressed down again. At this time, the semi-finished product in the trimming chamber 142 on the right side is processed and formed (formed into a terminal). The semi-finished product in the middle position has achieved the forging of the solid part. Then, the first drive source 144 drives the first slider 143 to return to its initial position (the first slider 143 moves to the left). At this time, the forged semi-finished product located in the middle position moves to the trimming cavity 142 on the left, and the processed terminal is located in the middle position. The semi-finished product feeding can push the formed terminal to the outside, so that the semi-finished product enters the forging cavity 141, and the second stamping part 145 begins to press down again. The semi-finished product located in the trimming cavity 142 on the left is formed, and the semi-finished product in the middle position is forged. The slider continues to move, so that the slider moves to the right, thereby achieving a reciprocating motion effect. Here, the second stamping part 145 can be driven by a cylinder, a hydraulic cylinder, or other power device.

[0060] Specifically, as shown in the attached document Figures 2-6 As shown, it also includes a second conduit 19, which connects the stretching device 11 and the round-mouth device 13. The bar stock processed in one step enters the round-mouth device 13 through the second conduit 19. The second conduit 19 also serves as a guide and transporter, achieving precise positioning. Here, the second conduit 19 is identical to the first conduit 18, both being transparent tubular structures.

[0061] Specifically, as shown in the attached document Figures 2-6As shown, the stretching device 11 may also include a turntable 112, which has several slots. The solid bar stock conveyed by the first lifting device 12 is installed in the slots, and then rotated by the turntable 112 to the area below the first stamping part 111, forming a stamping and stretching operation. After processing, the bar stock processed in one operation enters the round-mouth device 13 through the second guide tube 19 by rotating the turntable 112. Alternatively, it can be arranged in a guide rail manner to form stamping operations one by one. The turntable 112 can be driven by a rotating motor, a pneumatic cylinder, or a hydraulic cylinder.

[0062] Specifically, as shown in the attached document Figures 2-6 As shown, the rounding device 13 also includes a fixing structure, which fixes the bar stock for the first processing step, and then performs chamfering processing using a chamfering component 131. The chamfering component 131 can be a milling cutter or other chamfering tool. The fixing structure can be a clamping component, providing a clamping and fixing effect. The clamping component can be driven by a rotating motor, pneumatic cylinder, or hydraulic cylinder.

[0063] Specifically, the first lifting device 12, the second lifting device 15, and the third lifting device 16 can be tracked conveyors or other types of conveyors, such as belt conveyors or other structures.

[0064] Specifically, as shown in the attached document Figures 2-6 As shown, the system also includes a non-powered feeding conveyor belt 20 and a collection box 21. One end of the non-powered feeding conveyor belt 20 is connected to the integrated device 14, and the other end is connected to the collection box 21. The non-powered feeding conveyor belt 20 and the collection box 21 are configured so that after the terminals are processed, they slide from the non-powered feeding conveyor belt 20 to the collection box 21 under the action of gravity for terminal collection. Here, the semi-finished product loading position is located at the front, and then the non-powered feeding conveyor belt 20 is at the rear. When the semi-finished product enters the integrated device 14, the unprocessed semi-finished product will push out the processed terminals, causing the terminals to move to the non-powered feeding conveyor belt 20.

[0065] Specifically, as shown in the attached document Figures 2-6 As shown, it also includes an automatic counting device 22, which counts the number of terminals that slip off the unpowered feed conveyor belt 20. The automatic counting device 22 is used to count and replace another collection box 21 when the number in the collection box 21 reaches a preset value. Here, the automatic counting device 22 can be an infrared sensor, a Hall sensor, or other counting device.

[0066] Specifically, as shown in the attached document Figures 2-6As shown, it also includes an automatic conveying device 23, on which collection boxes 21 are arrayed. The automatic conveying device 23 works in conjunction with an automatic counting device 22 to achieve automated operation. Here, the production line has a control assembly. The control assembly receives information from the automatic counting device 22, determines whether the container is full, and then controls the automatic conveying device 23 to move the empty collection boxes 21 to the lower end of the unpowered feeding belt 20. The control method here can be PLC control. The automatic conveying device 23 can be a conveyor belt or a roller conveyor.

[0067] Specifically, it also includes a palletizing area 24, where collection boxes 21 are palletized. Palletizing can be done here using a multi-axis robot or manually.

[0068] Specifically, the production line is arranged in a U-shape. This U-shape creates a compact structure, reducing the floor space required. Those skilled in the art can adjust the positional relationships of the production line according to actual needs. Here, the solid bar stock is processed into terminals on the same horizontal line, the collection and stacking are on the same horizontal line, and the unpowered feeding conveyor belt 20 connects the two horizontal lines, thus forming an overall U-shaped structure.

[0069] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
