[0058] The invention will be further described below with reference to specific embodiments:

[0059] like Figure 1 The lead-acid battery terminal shown is a common terminal structure, typically a rotating lead component. This component has an inner hole 01, a toothed ring 04 around its periphery, and multiple raised rings 02. An annular groove 03 is formed between adjacent raised rings for fitting with a plastic end cap. This embodiment uses this lead-acid battery to illustrate the structure of its molding equipment.

[0060] likeFigures 2-8 As shown, the present embodiment provides a lead-acid battery terminal forming device, which comprises a rack 10, a side mold assembly 20 mounted on the rack 10, and a first movable mold assembly 30 and a second movable mold assembly 40 respectively located on both sides of the side mold assembly 20; preferably, it further comprises a feeding assembly 50, a vibrating feeder 60, and a backup mold assembly 70 located between the first movable mold assembly 30 and the side mold assembly 20, wherein the vibrating feeder 60 is a conventional vibrating feeder device that can be directly purchased from the market and is not the focus of the present embodiment, and therefore will not be described in detail here. It should be noted that since the driving devices of each assembly can be mounted on the rack or externally (i.e. directly placed beside the rack 10 or even placed away from the rack 10 and connected through pipes, etc.), their positions are difficult to define. In order to facilitate representation, in the present embodiment, the positions of each assembly are taken as the positions of the executing members or driven members of each assembly, i.e. when describing the positions of each assembly, the positions of the corresponding driving devices of each assembly are not considered.

[0061] The rack 10 is provided with a base plate 11, which is vertically arranged, of course, the base plate 11 can also be horizontally arranged, and in the present embodiment, the vertically arranged base plate 11 is taken as an example for description. The base plate 11 is provided with a horizontally arranged mold opening and closing slide rail 12, which comprises a base 13 and two pressing plates 14 fixedly connected to the base 13 respectively, wherein the base 13 is provided with a horizontally arranged sliding groove for the side mold 21 to be mentioned below to slide, and the two pressing plates 14 cover the slots of the sliding groove and are respectively located at both ends of the sliding groove, of course, the feeding space is formed between the two pressing plates 14, which helps to prevent the side mold 21 to be mentioned below from derailing.

[0062] The side mold assembly 20 includes two oppositely arranged side molds 21 and a side mold driving device 22 for driving the two side molds 21 to move towards or away from each other, wherein the side mold driving device 22 can be a conventional device such as a cylinder, a push rod motor or a rotary motor cooperating with a crank linkage mechanism, etc. In the present embodiment, the side mold driving device 22 is a hydraulic cylinder fixedly connected to the base plate 11, and there are two hydraulic cylinders, each corresponding to one of the two side molds 21 and located on the two sides of the straight line direction of the slide groove. Each side mold 21 is slidingly connected to the same mold opening and closing slide rail 12. In this way, the two side molds 21 can be driven by the two hydraulic cylinders to perform linear mold opening action (two side molds 21 moving away from each other) and mold closing action (two side molds 21 moving towards each other). Each side mold 21 is provided with a mold groove 23. After the two side molds 21 abut each other (i.e. after mold closing), the two mold grooves 23 together form a mold hole 24 for forming the lead-acid storage battery terminal. It should be noted that the mold hole 24 can independently form the mold cavity of the lead-acid storage battery terminal, or can form part of the mold cavity of the lead-acid storage battery terminal. In the present embodiment, the mold hole 24 forms part of the mold cavity of the lead-acid storage battery terminal, which together with the counterbore 77 mentioned below forms the mold cavity of the lead-acid storage battery terminal. Of course, the mold hole 24 should correspond to the part of the lead-acid storage battery terminal with the convex ring 02. In addition, a semicircular groove can also be formed on each side mold 21. After the two side molds 21 abut each other (i.e. after mold closing), the two semicircular grooves together form a positioning hole for limiting the position of the second striker 41 mentioned below. The diameter of the positioning hole is greater than the maximum diameter of the mold hole 24.

[0063] The first movable mold assembly 30 includes a first striker 31 coaxially arranged with the mold hole 24 and a first driving device 32 for driving the first striker 31 to move along the axis direction of the mold hole 24, wherein the first driving device 32 can be a conventional device such as a motor, etc. In the present embodiment, the first driving device 32 is a hydraulic cylinder fixedly connected to the rack 10. Specifically, the rack 10 is provided with a first mounting plate 15 arranged parallel to the base plate 11, and the first mounting plate 15 is located on the side of the base plate 11 away from the first movable mold assembly 30. The above-mentioned hydraulic cylinder is mounted on the side of the first mounting plate 15 away from the base plate 11. A first connecting plate 33 is fixedly connected to the piston rod of the hydraulic cylinder. The first connecting plate 33 is fixedly connected with a first guide column 34 which is slidingly inserted into the base plate 11 and the first mounting plate 15 in sequence. The first guide column 34 is fixedly connected at the end away from the first connecting plate 33 with a first support plate 35. The first support plate 35 and the first connecting plate 33 are respectively located on the two sides of the base plate 11. The first striker 31 is fixedly connected to the first support plate 35. Of course, a through hole needs to be formed on the base plate 11 for the first striker 31 to pass through, so that the first striker 31 enters the mold hole 24 through the through hole.

[0064] The second movable die assembly 40 comprises a second punch 41 coaxially arranged with the mold hole 24 and a second driving device 42 for driving the second punch 41 to move along the axial direction of the mold hole 24, wherein the second driving device 42 can be a conventional device such as a motor, etc. In the embodiment, the second driving device 42 is also a hydraulic cylinder fixedly connected to the frame 10. Specifically, the frame 10 is provided with a second mounting plate 16 arranged parallel to the base plate 11, and the second mounting plate 16 is located between the first mounting plate 15 and the base plate 11. The hydraulic cylinder is mounted on the side of the second mounting plate 16 facing the base plate 11. The piston rod of the hydraulic cylinder is fixedly connected to a second support plate 43, and the second punch 41 is fixedly connected to the second support plate 43. Preferably, in order to ensure the movement accuracy of the second punch 41, the first guide column 34 is simultaneously slidably inserted into the second support plate 43 and the second mounting plate 16, and preferably there are two or more first guide columns 34. In this way, the first guide column 34 can provide guidance for the second support plate 43, thereby ensuring the movement accuracy of the second punch 41. Further, in the embodiment, the second support plate 43 is also fixedly connected to a second guide column 44, and the second guide column 44 is slidably inserted into the second mounting plate 16. The end of the second guide column 44 away from the second support plate 43 is fixedly connected to a limiting plate 45, i.e. the limiting plate 45 is located on the side of the second mounting plate 16 away from the base plate 11. The first guide column 34 is also slidably inserted into the limiting plate 45.

[0065] The three hydraulic cylinders are all connected to an oil tank 80, which is arranged at the lower part of the frame 10, thereby helping to increase the stability of the lower disc of the frame 10.

[0066] When in use, the lead block can be sent into the mold hole 24 by artificial or by mechanical hand. Considering that the operation space of the mold hole 24 position is relatively small, it is not conducive to quickly send the lead block. Therefore, in the embodiment, the feeding assembly 50 mentioned above is further arranged on the base plate 11. The feeding assembly 50 comprises a feeding piece 51 and a feeding driving device 52 for driving the feeding piece 51 to move from the radial direction of the mold hole to the direction of the mold hole. The feeding driving device 52 can be a conventional device such as a motor, etc. In the embodiment, the feeding driving device 52 is a hydraulic oil cylinder which is fixedly connected to the base plate 11 and the piston rod is arranged vertically downward. The feeding piece 51 is provided with a material hole 53. When the feeding piece 51 is moved to the position corresponding to the mold hole 24, the material hole 53 is located on the same straight line with the mold hole 24, and the feeding piece 51 is tightly attached to or close to the side of the side mold 21 which faces the side of the first movable mold assembly 30. In this way, the lead block can be first sent into the material hole 53 and then sent to the position of the mold hole 24 by the feeding driving device 52, and then sent into the mold hole 24 by the first punch 31. In this way, the operation space of the worker or the mechanical hand can be changed from the position of the mold hole 24 to the position above the mold hole 24 (of course, it can also be changed to the position below or beside the mold hole 24 according to actual needs), and the operation space is larger, which is convenient for quickly sending the lead block. Specifically, the feeding assembly 50 further comprises a guide block 54 connected between the feeding piece 51 and the feeding driving device 52, a guide sliding rail 55 matched with the guide block 54, and the guide block 54 is slidingly connected to the guide sliding rail 55, so as to ensure that the feeding piece 51 can accurately feed. The guide sliding rail 55 comprises a sliding seat 58 and a cover plate 56. The sliding seat 58 is provided with a vertical guide groove, and the cover plate 56 covers the groove of the guide groove. The feeding piece 51 comprises two swing blocks 57 which are respectively rotationally connected to the guide block 54 and arranged opposite to each other. The swing blocks 57 are respectively provided with a semicircular groove on the side facing each other. The two semicircular grooves form the material hole 53 after the two swing blocks 57 are close to each other. A tension spring (not shown in the figure) is arranged between the two swing blocks 57, so as to ensure that the two swing blocks 57 are always close to each other under the action of no external force. The two swing blocks 57 which are close to each other can slide on the guide sliding rail 55. In addition, when the feeding piece 51 moves to the limit position away from the mold hole 24, the material hole 53 is connected with the discharge end of the vibrating feeder 60. It should be noted that the limit position of the feeding piece 51 moving away from the mold hole 24 is not only the limit position of the feeding piece 51, but also the limit position required by the vibrating feeder 60 according to the position of the discharge end.

[0067] The die assembly 70 comprises a die seat 71 and a die driving device 72 for driving the die seat 71 to move along the axial direction of the mold hole 24, wherein the die driving device 72 can be a conventional device such as a motor, etc., and in the embodiment, the die driving device 72 is also a hydraulic cylinder fixedly connected to the rack 10. Specifically, the rack 10 is provided with a third mounting plate 17 arranged parallel to the base plate 11, the third mounting plate 17 is located between the first mounting plate 15 and the second mounting plate 16, the hydraulic cylinder is mounted on the side of the third mounting plate 17 away from the second mounting plate 16, a piston rod of the hydraulic cylinder is fixedly connected with a die connecting plate 73, the die connecting plate 73 is fixedly connected with a die guide column 74, the die guide column 74 is fixedly connected with a die support plate 75, and the die guide column 74 is sequentially and slidably inserted into the third mounting plate 17, the second mounting plate 16 and the base plate 11, and the die seat 71 is fixedly connected to the die support plate 75. In addition, the first guide column 34 is also slidably inserted into the third mounting plate 17 and the die support plate 75.

[0068] The die seat 71 is provided with a needle hole 76 coaxially arranged with the mold hole 24, so that the first punch 31 can pass through the needle hole 76 and enter the mold hole 24. Preferably, the die seat 71 is also provided with a counterbore 77 coaxially arranged with the needle hole 76, the counterbore 77 is located on the side of the die seat 51 facing the mold hole 24, and the counterbore 77 and the mold hole 24 jointly form a mold cavity of the lead-acid battery terminal. Since the counterbore 77 is not formed by splicing two grooves, it helps to reduce the reaction force of the material required to be borne by the side mold 21 during molding, and avoids the phenomenon of "expanding mold".

[0069] In use, the lead piece is placed in the vibrating feeder 60, wherein the lead piece is a cylindrical component, the length and diameter of which are smaller than the length and diameter of the lead-acid storage battery terminal and the minimum diameter of the mold hole 24; the lead piece is sent into the material hole 53 under the driving of the vibrating feeder 60, at this time the feeding piece 51 is located on the guide rail 55, and the two swing blocks 57 of the feeding piece 51 are limited by the guide groove side wall and cannot be opened away from each other, and the two side molds 21 perform the mold closing action; then, the feeding piece 51 moves in the direction of the mold hole 24, so that the material hole 53 and the mold hole 24 are located on the same straight line, and in this process, the two swing blocks 57 are ensured not to be opened away from each other by the tension spring; then, the first punch 31 pushes the lead piece into the mold hole 24 and resets, so as to reset the feeding assembly 50; after the feeding assembly 50 is reset, the die holder 71 moves in the direction of the mold hole 24 to press the side mold 21 on the base plate 11, and the lead piece penetrates the counterbore 77; then, the first punch 31 and the second punch 41 move towards each other, and at the same time, the lead piece in the mold hole 24 is extruded, so that the lead piece is deformed and fills the mold cavity, the terminal blank; then, the first punch 31 continues to move in the direction of the second punch 41, and at the same time, the second punch 41 retreats, or the second punch 41 continues to move in the direction of the first punch 31, and at the same time, the first punch 31 retreats, so as to separate the possible thin layer of lead material between the first punch 31 and the second punch 41 from the blank, and form the lead-acid storage battery terminal; finally, the first punch 31 and the second punch 41 are reset first, and then the die holder 71 is reset, and the two side molds 21 perform the mold opening action, to complete a molding cycle action.

[0070] The above describes the present application in detail in combination with the drawings, but the implementation of the present application is not limited to the above-mentioned implementation, and those skilled in the art can make various modifications to the present application according to the prior art, such as changing the oil cylinder in the above-mentioned embodiment to a gas cylinder, etc., which all belong to the protection scope of the present application.
