Description

Technical Field

[0001] The utility model relates to the technical field of cold welding machines, in particular to a new type of desktop cold welding machine. Background Art

[0002] A cold welding machine is also called a wire cold welding machine, a wire connecting machine, a hydraulic cold welding machine, etc. It can be divided into a pliers type, a desktop cold welding machine and a hydraulic type cold welding machine according to its use and shape. A cold welding machine is a device that does not require any additives, electrical energy, fillers and fluxes. It makes metal wire pass through a die and applies a certain pressure. Under the action of a concentrated pressure load, the surface area of the two contact surfaces to be connected is enlarged. The enlargement of the area causes the original protective film that hinders welding on the surface to break, and the external load makes the exposed pure metal matrix contact tightly, so as to produce a new combination between atoms, realize the connection principle of molecular atomic structure, and thus weld various non-ferrous metal materials.

[0003] When using a cold welding machine, by pressing the handle, the two push rods move synchronously inward, and at the same time drive the connected push blocks to move relative to each other, so that the die located between the two push blocks produces an extrusion effect in the direction perpendicular to the movement direction of the push blocks, thus realizing the cold welding operation. However, the existing cold welding machines can usually only perform cold welding on metal wires of one specification during the operation process. For wires of different specifications, the die needs to be replaced, and the replacement time affects the working effect. And the existing cold welding machines are generally equipped with a trolley to fix the main body of the cold welding machine on the trolley. However, in formal production, the position of the copper wire is not fixed. Due to the fixed height of the cold welding machine, it is not easy to adjust, which brings a lot of inconvenience to the use. Therefore, a new type of desktop cold welding machine is needed to meet people's needs. Summary of the Utility Model

[0020] 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.

[0021] Refer to Figures 1-4 , a new type of desktop cold welding machine, including a top plate 1. A plurality of legs 2 are connected to the bottom end of the top plate 1. A universal wheel 3 is connected to the bottom end of each leg 2. A handrail 4 is arranged on one side of the top plate 1. A worm 5 is rotatably connected below the top plate 1. One end of the worm 5 is connected to a rotating shaft 6. One end of the rotating shaft 6 is connected to a handwheel 7. A worm gear 8 is rotatably installed at the bottom end of the top plate 1. The worm gear 8 meshes with the worm 5. A screw rod 9 is threadedly connected inside the worm gear 8. The screw rod 9 penetrates through the top plate 1 and extends upward. The top end of the screw rod 9 is movably connected to a support plate 10. A cold welding machine body 11 is connected to the support plate 10. A handle 12 is rotatably connected to one side of the cold welding machine body 11. Two push rods 13 are movably connected to the cold welding machine body 11. The two push rods 13 are drivingly connected to the handle 12. A push block 14 is movably connected to each of the two push rods 13. A fixed block 15 is connected to the cold welding machine body 11. The fixed block 15 is located between the two push blocks 14. A mold 16 is movably installed between each push block 14 and the fixed block 15.

[0022] By movably installing a mold 16 between each of the two push blocks 14 and the fixed block 15, when the handle 12 is pressed down, the two push rods 13 drive the connected push blocks 14 to approach each other respectively. Since the fixed block 15 is stationary, the two molds 16 move toward the fixed block 15 under the thrust of the push blocks 14 respectively, thereby realizing the synchronous cold welding operation of the two molds 16. The cold welding machine can install different molds 16 according to the specifications, thicknesses, etc. of different metal materials, so that different types of metal materials can be welded, and even multiple metal materials can be welded at one time, thereby improving work efficiency.

[0023] Rotate the handwheel 7 so that the rotating shaft 6 drives the worm 5 to rotate. The worm 5 drives the worm wheel 8 to engage and rotate, so that the screw rod 9 drives the support plate 10 to move vertically, thereby realizing the lifting adjustment of the cold welding machine body 11. The self-locking property between the worm 5 and the worm wheel 8 realizes the stability of the lifting adjustment. The cooperation between this lifting adjustment mechanism and the universal wheel 3 with a built-in brake can, in the process of formal production, in case of metal material fracture, difficult position adjustment or inability to directly take out, etc., directly change the position of the cold welding machine without moving the position of the metal material, solving the problem that it is inconvenient to adjust the main body of the metal material when using the cold welding machine and the need for handling during adjustment.

[0026] Specifically, in this embodiment, a connecting ring 19 is connected to the top end of the worm wheel 8. The unilateral cross-section of the connecting ring 19 is L-shaped. The connecting ring 19 is rotatably connected inside the bottom end of the top plate 1, ensuring the smooth rotation of the worm wheel 8 while providing vertical positioning for the worm wheel 8 and ensuring the meshing between the worm wheel 8 and the worm 5.

[0027] Specifically, in this embodiment, a threaded hole 20 is opened at the center of the worm wheel 8. The screw rod 9 is threadedly connected in the threaded hole 20, so that the rotation of the worm wheel 8 realizes the purpose of the vertical movement of the screw rod 9.

[0028] Specifically, in this embodiment, a through hole 21 is opened on the top plate 1. The screw rod 9 is located inside the through hole 21. The inner diameter of the through hole 21 is larger than the outer diameter of the screw rod 9, facilitating the insertion of the screw rod 9 inside the top plate 1 to realize the lifting adjustment.

[0029] Specifically, in this embodiment, several guide rods 22 are connected to the bottom end of the support plate 10. Each guide rod 22 is arranged at the corner of the support plate 10 and is slidably connected inside the top plate 1, further ensuring the verticality of the lifting of the support plate 10 and the stability during the lifting process of the support plate 10.
