Description

Technical Field

[0001] This utility model relates to the field of extrusion press technology, and in particular to a copper plate extrusion press. Background Technology

[0002] As the core conductive component of electrical switches, the manufacturing process of copper contacts directly affects product performance. Traditional production processes involve mixing copper powder into an alloy, die-casting it into copper rods, sintering the rods at high temperatures, and then placing the sintered rods in an extruder at high temperatures for multiple extrusion and cutting processes to form the contacts. The key process lies in the copper plate forming stage.

[0003] In existing multi-stage extrusion processes for copper rods, after a single extrusion molding, the rods need to be transferred to other equipment for secondary extrusion. This results in positioning errors between processes and affects work efficiency. Furthermore, the copper rods are prone to rolling deviation during extrusion, causing unilateral overpressure and resulting in a "wavy" defect on the plate edge. In view of this, this application proposes a copper plate extrusion machine. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] This utility model provides a technical solution: such as Figure 1-4 As shown, a copper plate extrusion machine includes a housing 1. Cover plates 2 are fixedly installed on both outer sides of the housing 1. Each cover plate 2 has a feed inlet 4 on its outer side and a viewing window 3 on its outer side. A pressure seat 8 is rotatably connected to the bottom wall of the housing 1. The housing 1 drives the pressure seat 8 to rotate via a rotating mechanism. A support column 22 is fixedly installed inside the pressure seat 8. A fixed seat 27 is fixedly installed on the outer side of the support column 22. A sliding seat 23 is slidably connected to the outer side of the support column 22. A symmetrically mounted support is installed on the top surface of the sliding seat 23. Two movable plates 21, a spring 24 is installed between the bottom surface of the sliding seat 23 and the top surface of the fixed seat 27. Two limiting mechanisms are symmetrically installed on the inner wall of the pressure seat 8, and the limiting mechanisms restrict the position of the sliding seat 23. Two pressure blocks 20 are symmetrically slidably connected inside the housing 1. The housing 1 drives the two pressure blocks 20 to slide towards each other through the driving mechanism. A pressure plate 7 is installed on the top wall of the housing 1 through the first electric telescopic rod 6. Two connecting plates are symmetrically installed on the bottom surface of the pressure plate 7. A conveying mechanism is installed on one side of each cover plate 2.

[0021] The copper rod can be positioned using two movable plates 21 to prevent it from shifting. It should also be noted that... Figure 2 and 3 As shown, the bottom of the pressure plate 7 has a connecting plate corresponding to the movable plate 21. The movable plate 21 can be squeezed through the connecting plate to ensure that the movable plate 21 is completely hidden in the pressure seat 8. The connecting plate and the movable plate 21 can limit the width of the copper rod extrusion.

[0022] Furthermore, the rotating mechanism can be used to rotate the pressure seat 8, thereby rotating the copper plate that can be extruded and formed. With the help of two pressure blocks 20, the length and width of the copper plate can be extruded a second time. With the help of springs 24, the moving plate 21 can be hidden in the pressure seat 8 when the copper rod is extruded and formed, and it can be limited by the limiting mechanism, so as to facilitate the subsequent secondary extrusion of the width and length of the copper plate.

[0023] Furthermore, the rotating mechanism includes a gear ring 9, which is installed on the outside of the pressure seat 8. A second motor 11 is fixedly installed on the bottom surface of the housing 1. The top output shaft of the second motor 11 passes through the housing 1 and is equipped with a gear 10. The gear 10 meshes with the gear ring 9. The gear 10 can drive the gear ring 9 to rotate slowly, which facilitates precise control of the rotation angle of the pressure seat 8.

[0024] Furthermore, the driving mechanism includes a double-ended screw 16, which is rotatably connected to the two side walls of the housing 1. Guide rods 17 are fixedly installed on the two side walls of the housing 1. Two threaded sleeves 18 are symmetrically threaded on the double-ended screw 16, and each threaded sleeve 18 is slidably connected to the guide rod 17. A connecting plate 19 is fixedly installed at the bottom end of each threaded sleeve 18, and each pressure block 20 is fixedly installed on the side of the corresponding connecting plate 19. A first motor 5 is fixedly installed on the outside of the housing 1, and the output shaft of the first motor 5 is coaxially connected to the double-ended screw 16. The double-ended screw 16 has two sections of threads with opposite directions, which can drive the two threaded sleeves 18 to slide towards or away from each other, so that the two pressure blocks 20 can simultaneously extrude steel plates.

[0025] Furthermore, the limiting mechanism includes two second electric telescopic rods 25, which are symmetrically installed on the side wall of the pressure seat 8. Each second electric telescopic rod 25 has a U-shaped seat 26 fixedly installed at the other end, so that the sliding seat 23 can be locked in the U-shaped seat 26, thereby limiting the sliding seat 23.

[0026] Furthermore, each conveying mechanism includes a conveying seat 12, and each conveying seat 12 is fixedly installed on the outside of the cover plate 2. Two baffles 13 are symmetrically installed on the top surface of each conveying seat 12. Multiple power rollers 14 are rotatably connected to the top surface of each conveying seat 12. Connecting plates 15 are fixedly installed on both outer sides of each conveying seat 12, and the other end of each connecting plate 15 is fixedly installed on the side wall of the housing 1. It should be noted that the power of the power rollers 14 is driven by an external drive source.

[0027] Furthermore, the bottom surface of each pressure block 20 is flush with the top surface of the pressure seat 8. The first motor 5 and the second motor 11 are both conical rotor motors, and their output shafts can be locked after power failure, which facilitates effective limiting of the connected devices.

[0028] This utility model provides a copper plate extrusion machine, and the specific working principle is as follows: First, the operator places the sintered copper rod through the material port 4 onto the power roller 14 of the conveying mechanism through the external equipment. The power roller 14 conveys the copper rod to the center position of the pressure seat 8 under the action of the external driving source. At this time, the two moving plates 21 on the sliding seat 23 are in the extended state under the action of the spring 24, which laterally limits the copper rod.

[0029] Next, the first electric telescopic rod 6 drives the pressure plate 7 to move downward, applying a vertical squeezing force to the copper rod. As the squeezing process proceeds, the copper rod gradually deforms. After the copper rod deforms, the pressure plate 7 can squeeze the movable plate 21 and squeeze the sliding seat 23. The spring 24 is compressed, and the sliding seat 23 slides downward along the support column 22.

[0030] When the sliding seat 23 descends to a specific position, the second electric telescopic rod 25 drives the U-shaped seat 26 to extend, locking the sliding seat 23 inside the U-shaped seat 26, thus hiding and limiting the moving plate 21. At this time, the copper rod is squeezed into a preliminary copper plate shape.

[0031] After extrusion, the first electric telescopic rod 6 drives the pressure plate 7 to rise and reset. Then, the second motor 11 starts and drives the pressure seat 8 to rotate slowly through the meshing transmission of the gear 10 and the gear ring 9, so that the steel plate turns. Finally, the first motor 5 drives the double-headed screw 16 to rotate. Since the double-headed screw 16 has two sections of threads with opposite directions, the two threaded sleeves 18 slide towards each other under the limit of the guide rod 17. Through the connecting plate 19, the two pressure blocks 20 are driven to extrude the copper plate inward synchronously. The length and width of the copper plate can be processed in a secondary forming process to ensure the dimensional accuracy of the copper plate.

[0032] After processing, the pressure block 20 returns to its original position, the pressure seat 8 rotates back to its initial position, the operator observes the internal situation through the viewing window 3, and pushes the formed copper plate onto the power roller 14 through the next copper rod, and the copper plate is discharged from the material outlet 4.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
