The pressing device for wire butt joint provided by the present invention will now be described.

As shown in Figures 1 to 4, the pressing device for wire butt joint provided by the first embodiment of the present invention includes a base box 1, a mounting plate 2, a first screw 5, a motor 6, two bevel teeth 7, a sleeve Plate 8, guide rod 11 and two position-limiting mechanisms, mounting plate 2 is fixedly arranged on the top of described base case 1, and described mounting plate 2 is provided with a plurality of pressure grooves 3, and in multiple described pressure grooves 3, each A rubber cushion 4 is fixedly installed; the first screw rod 5 is rotated at the bottom of the base box 1, and the bottom end of the first screw rod 5 extends into the base box 1; the motor 6 is fixedly installed on the base box 1; two bevel teeth 7 are respectively fixed on the output shaft of the motor 6 and the bottom end of the first screw 5, and the two bevel teeth 7 are meshed; the sleeve plate 8 is threaded on the On the first screw rod 5, one end of the sleeve plate 8 is fixedly mounted with a pressing plate 9, and the bottom of the pressing plate 9 is symmetrically fixed with a plurality of pressing blocks 10; On the plate 8, the bottom end of the guide rod 11 is fixedly connected with the top of the base box 1; two limit mechanisms are symmetrically arranged on the base box 1.

By setting a plurality of pressure grooves 3 with different inner diameters on the mounting plate 2, it is suitable for placing different thickness types of connecting pipes butt-fitting wires, and the rubber cushion layer 4 provided can play a cushioning role to avoid compression. Tube contact creates burrs and bumps. Through the operation of the set motor 6 and the cooperation with the bevel teeth 7, the first screw rod 5 can be driven to rotate and drive the sleeve plate 8 and the pressing plate 9 to move, and the set pressing block 10 can be used to squeeze the wiring tube after the pressing plate 9 is adjusted. Realize the compression butt joint of the wire.

When in use, fix the wire workpieces that need to be connected on the limit mechanisms on both sides of the base box 1, and make the joints rest in the pressure groove 3, and connect them well, then start the motor 6, and the running motor 6 outputs The shaft will drive the bevel gear 7 to drive the first screw 5 to rotate, and the rotating first screw 5 will drive the sleeve plate 8 and the compression plate 9 to move downward, and then the compression block 10 will connect the wiring tube, and the wiring tube will be depressed and penetrated under pressure. The butt joint limit of the lead wire that enters just completes the butt joint compaction according to this, and the rubber pad layer 4 and the rubber sleeve that are set can play a cushioning role, avoiding the burrs and protrusions generated by the pipe contact during compaction.

Further, on the basis of the above-mentioned first embodiment, the present invention provides another specific implementation as follows:

The end of the pressing block 10 used to cooperate with the pressure groove 3 is a non-Newtonian fluid member. When the end of the compression block 10 is just in contact with the workpiece, the end will deform along with the external shape of the workpiece, and in the process of further pressurization, the force on the end becomes larger rapidly, and hardening begins to occur, compressing the wire workpiece catch. This helps to maintain the external shape of the workpiece.

Specifically, the end of the pressing block 10 can be a structure in which a non-Newtonian fluid is provided in the flexible capsule, and a wear-resistant layer is provided on the outside of the flexible capsule to reduce wear, and the non-Newtonian fluid in the flexible capsule is in a pressurized state , the pressure is 1.5-4 standard atmospheric pressure, and the specific pressure is determined according to actual needs, so as to ensure that it is in a fluid state when the workpiece is not crimped, and quickly becomes solid when the workpiece is crimped.

Non-Newtonian fluids refer to fluids that do not satisfy Newton's experimental law of viscosity, that is, fluids that have a non-linear relationship between shear stress and shear strain rate. Non-Newtonian fluids widely exist in life, production and nature. The vast majority of biological fluids are now defined as non-Newtonian fluids. A variety of body fluids such as blood, lymph, and cystic fluid in the human body, as well as "semi-fluids" like cytoplasm, all belong to non-Newtonian fluids.

Concentrated solutions and suspensions of polymers are generally non-Newtonian fluids. Polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, polyester, rubber solutions, various engineering plastics, chemical fiber melts, solutions, etc., are all non-Newtonian fluids. Petroleum, mud, coal water slurry, ceramic slurry, paper pulp, paint, ink, toothpaste, silkworm silk regeneration solution, well cleaning fluid and completion fluid for drilling, magnetic slurry, coating fluid for certain photosensitive materials, foam, liquid crystal, Highly sandy water flow, debris flow, mantle, etc. are also non-Newtonian fluids. In the food industry, tomato juice, starch liquid, egg white, apple pulp, concentrated sugar water, soy sauce, jam, condensed milk, agar, potato pulp, melted chocolate, dough, rice noodles, and minced fish, minced meat and other minced food materials are also used Both are non-Newtonian fluids.
