Description

Technical Field

[0001] The utility model relates to the technical field of contact forming, and more specifically, to a hydrostatic press device for contact pressing and forming. Background Art

[0002] A contact is a key component used to connect and disconnect circuits in electrical switches, relays and other devices. It is usually made of materials with good electrical conductivity, such as silver, copper, etc. The contact realizes the on-off of the circuit through contact and separation, and its performance directly affects the reliability and service life of electrical equipment. The contact is usually formed by pressing. The contact material, such as silver-based alloy, etc., is placed in a specific mold. Under high pressure, the contact material is gradually compressed and formed. The pressure is maintained for a period of time to ensure that the material is fully compacted and internal pores are eliminated. Then, the pressure is released, the mold is opened, and the pressed contact is taken out. After subsequent processing such as grinding, a contact that meets the requirements can be obtained to meet the functional requirements of connecting and disconnecting circuits in electrical equipment.

[0003] The materials of the contact usually adopt silver-based alloy, copper-based alloy and other materials. During the high-pressure pressing process, there is a certain adhesion force between the material and the mold, causing a part of the material to adhere to the inside of the mold. Therefore, after each contact forming and taking out, it is necessary to manually clean the inside of the mold. Manual cleaning undoubtedly increases the labor cost, and at the same time, when manually cleaning, a part of the body needs to be inserted into the mold, which has certain safety hazards.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A hydrostatic press device for contact pressing and forming includes a base. A slide plate is longitudinally slidably connected to the top surface of the base. An upper mold is fixedly installed on the bottom surface of the slide plate. The base drives the slide plate to slide through a hydraulic mechanism.

[0016] 1.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Referring to Figures 1-5 , a hydrostatic press device for contact pressing and forming includes a base 1. A slide plate 5 is longitudinally slidably connected to the top surface of the base 1. An upper mold 6 is fixedly installed on the bottom surface of the slide plate 5. The base 1 drives the slide plate 5 to slide through a hydraulic mechanism. A lower mold 7 is fixedly installed on the top surface of the base 1. A plurality of spring telescopic rods 13 are symmetrically installed on the bottom wall of the base 1. The other ends of the plurality of spring telescopic rods 13 are jointly installed with a mounting plate 14. A cleaning rod 16 is rotatably connected inside the mounting plate 14. One end of the cleaning rod 16 is rotatably connected to a base 24, and the base 24 is slidably connected inside the lower mold 7. A plurality of cleaning plates 23 are fixedly installed on the outer side of the cleaning rod 16, and one end of each cleaning plate 23 is in contact with the inner wall of the lower mold 7. A knocking and vibrating mechanism is installed on the top surface of the base 1.

[0027] As Figures 1-5 shown, the implementation method is specifically as follows: By setting a plurality of spring telescopic rods 13, the mounting plate 14 is driven to jack up and reset, so as to extrude the formed contact out of the lower mold 7 through the base 24. By setting the cleaning rod 16 and the cleaning plates 23, the cleaning plates 23 can be driven to clean the lower mold 7 by the rotation of the cleaning rod 16.

[0028] The knocking and vibrating mechanism includes a gear ring 8, and the gear ring 8 is rotatably connected to the top surface of the base 1. A plurality of rotating shafts 10 are rotatably connected to the top surface of the base 1. A driven gear 9 is installed at the bottom end of each rotating shaft 10, and each driven gear 9 meshes with the gear ring 8. A plurality of knocking rods 11 are fixedly installed on the outer side of each rotating shaft 10.

[0029] The rotation of the gear ring 8 drives the rotation of each driven gear 9, and then drives the rotation of each rotating shaft 10, and the lower mold 7 is knocked by the knocking rods 11. During the process of pressing the contact, knocking the lower mold 7 can make the material distribution of the contact more uniform and dense, and reduce internal pores and defects.

[0030] A turntable 20 is rotatably connected inside the mounting plate 14. A telescopic seat 17 is fixedly installed on the top surface of the turntable 20. A sliding seat 18 is slidably connected inside the telescopic seat 17. The top end of the sliding seat 18 is fixedly installed with a connecting shaft 19. The top end of the connecting shaft 19 penetrates through the base 1 and is installed with a driving gear 12, and the driving gear 12 meshes with the gear ring 8.

[0031] Drive the ring gear 8 to rotate through the drive gear 12.

[0032] The hydraulic mechanism includes a plurality of guide posts 2, and the plurality of guide posts 2 are symmetrically installed on the top surface of the base 1. The top ends of the plurality of guide posts 2 are jointly installed with a top plate 3. A hydraulic rod 4 is fixedly installed on the top surface of the top plate 3, and the bottom end of the hydraulic rod 4 is fixedly connected to the top surface of the sliding plate 5.

[0033] A square cavity is formed in the sliding seat 18, and each side surface of the telescopic seat 17 is attached to the side wall of the sliding seat 18. Thus, the telescopic seat 17 can be driven to rotate synchronously by the rotation of the sliding seat 18.

[0034] A motor 15 is fixedly installed on the bottom surface of the mounting plate 14, and the output shaft of the motor 15 is connected to the bottom surface of the turntable 20.

[0035] Synchronous wheels 21 are installed on the output shaft of the motor 15 and the bottom end of the cleaning rod 16, and the two synchronous wheels 21 are jointly sleeved with a synchronous belt 22.

[0036] The material of each knocking rod 11 is rubber, which is used to reduce the damage to the lower die 7.

[0037] When the utility model is in use, first place the material of the contact head in the lower die 7, and lift the material through the base 24. Then, start the hydraulic rod 4 to drive the sliding plate 5 to slide downward, so as to press the material in the lower die 7 through the upper die 6.

[0038] During the pressing process, the motor 15 can be started. The motor 15 drives the turntable 20 to rotate. Then, since the sliding seat 18 and the telescopic seat 17 are both square, the drive gear 12 on the connecting shaft 19 is driven to rotate, and then the ring gear 8 is pushed to rotate. Since each driven gear 9 is meshed with the ring gear 8, each rotating shaft 10 is driven to rotate, and the outer side of the lower die 7 is knocked by the knocking rod 11, so that the material in the lower die 7 is more closely connected, more evenly and densely distributed, and the internal pores and defects are reduced. It should be noted that at this time, the output shaft of the motor 15 drives the cleaning rod 16 to rotate through the synchronous wheel 21 and the synchronous belt 22. However, since there is friction between the material and the base 24, and there is friction between the material and the side wall of the lower die 7, and the cleaning rod 16 is rotatably connected to the base 24, the rotation of the cleaning rod 16 will not drive the base 24 to rotate, which is convenient for the forming of the contact head.

[0039] After pressing and forming, the upper mold 6 is slid upward, so that the base 24 slides upward under the action of the spring telescopic rod 13 and pushes the contact to separate from the lower mold 7. At the same time, after the mounting plate 14 rises, each cleaning plate 23 is located inside the lower mold 7, and then the cleaning rod 16 is driven to rotate by the motor 15 to realize the cleaning of the inner wall of the lower mold 7 through the cleaning plate 23. At the same time, the material adhering to the lower mold 7 can be quickly fallen off by knocking with the external knocking rod 11, thereby improving the cleaning efficiency.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
