Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a serpentine tube pressing mold. Background Technology

[0002] The serpentine tube pressing mold is a specialized tooling equipment used to process metal tubes into continuously bent, snake-shaped tubular parts. Its working principle is to use the synergistic effect of the mold cavity structure and the pressing mechanism to gradually or in one go press the straight tube blank according to the preset bending radius, pitch and length requirements. The entire process requires precise control of pressure, temperature and feed speed to ensure the bending accuracy and tube wall integrity of the serpentine tube. The mold consists of upper and lower mold bases and a guiding mechanism. It is widely used in the manufacturing of core components for air conditioner condensers, evaporators, automotive radiators and industrial heat exchangers, and is a key piece of equipment for realizing the large-scale and high-precision production of serpentine tubes.

[0003] Existing serpentine tube pressing molds employ a double protection mechanism of bolt locking and locating pins to prevent component displacement during pressing, ensuring consistent bending radius and pitch of the serpentine tubes. However, the connection relies on multiple hexagonal socket head cap bolts, requiring each bolt to be loosened and removed individually with a special wrench during replacement, and then tightened again after installing a new component, which is extremely time-consuming and labor-intensive. Current technology uses a quick-change structure to fix the mold, with a T-shaped boss designed at the bottom of the mold component. After embedding into the T-slot of the mold base, it is quickly locked by side clamping blocks without removing bolts, significantly shortening mold change time. However, the positioning of the clamping blocks depends on stable air pressure output. After long-term use, the pneumatic system requires regular cleaning of the air filter (to prevent dust blockage and pressure instability) and replacement of the sealing ring to prevent air leakage, greatly increasing equipment operating costs. Utility Model Content

[0039] Specifically, rotating the adjusting turntable 3031 allows the drive shaft 3032 on its outer wall to rotate in the middle of the second mounting frame 302, thereby driving the right-end gear 3034 to rotate as well. Simultaneously, the ratchet 3033 on the left end of the drive shaft 3032 rotates synchronously. The bottom end of the outer wall of the pawl holder 3036 engages with the inner wall of the second mounting frame 302 to limit the ratchet 3033, preventing the drive shaft 3032 from reversing. Through the meshing of the gear 3034 and the front rack 3035, the rack 3035 slides inside the second mounting frame 302, driving the driven roller 301 to adjust its position to accommodate pipes of different sizes.

By adjusting the distance between the two rollers, pipes of different sizes can be conveyed.

[0040] Reference Figure 1 , Figure 2 and Figure 4 The inner wall of the machine body 1 is fixedly connected to the top left and right sides of the buffer frame 4. The buffer frame 4 is equipped with buffer springs 5. The bottom front end of the outer wall of the machine body 1 is equipped with a drive roller 6. The right side of the outer wall of the drive roller 6 is equipped with a motor 7. The model of the motor 7 is MSME102G1V. Its working principle is that when DC current is applied to the armature winding, the current is subjected to Ampere force in the magnetic field. Under the action of force, the armature winding drives the rotor to rotate. However, due to the cooperation of the commutator and the brush, the current direction in the winding will automatically reverse every time the rotor rotates half a revolution. To ensure that the rotor is continuously subjected to torque in the same direction and achieve continuous rotation, an operating table 8 is fixedly connected to the bottom of the outer wall of the machine body 1, and a support frame 9 is fixedly connected to the bottom of the outer wall of the operating table 8.

The second mounting frame 302 is welded to the machine body 1 through the second welding frame 11 and the first welding frame 10. The various components cooperate with each other, which not only ensures the stability of the machine body 1 during operation, but also enhances the firmness of the installation of the relevant components.

[0042] Working principle: After placing the upper and lower parts of the mold 12 into their respective positions, rotating the knob 2031 causes the worm gear 2032 welded to its rear side to rotate inside the first mounting bracket 201. Through the meshing of the worm gear 2032 and the worm wheel 2033, the worm wheel 2033 drives the rotating shaft 2034 welded in the middle to rotate inside the first mounting bracket 201, thereby driving the first bevel gear 2035 to rotate as well. Through the meshing of the first bevel gear 2035 and the two second bevel gears 2036, the second bevel gears 2036 drive the threaded rod 2037 in the middle to rotate, thereby causing the threaded block 2038 to slide along the slide groove 202, moving multiple threaded blocks 2038 into the fixing groove 204 respectively, thus completing the fixation of the mold 12 at the top of the machine body 1. Reverse rotation of the knob 2031 allows the threaded block 2038 to disengage from the fixing groove 204, realizing the quick disassembly of the mold 12, improving the efficiency of mold assembly and disassembly while reducing equipment operating costs.

[0043] Rotating the adjusting turntable 3031 allows the drive shaft 3032 on its outer wall to rotate in the middle of the second mounting frame 302, thereby driving the right-end gear 3034 to rotate as well. Simultaneously, the ratchet 3033 on the left end of the drive shaft 3032 rotates synchronously. The bottom end of the outer wall of the pawl holder 3036 engages with the inner wall of the second mounting frame 302 to limit the ratchet 3033, preventing the drive shaft 3032 from reversing. Through the meshing of the gear 3034 and the front rack 3035, the rack 3035 slides inside the second mounting frame 302, driving the driven roller 301 to adjust its position to accommodate pipes of different sizes. When reverse adjustment is required, pulling the ratchet holder 3036 along the top of the second mounting frame 302 releases the limitation on the ratchet 3033, allowing the adjusting turntable 3031 to rotate in the reverse direction. By adjusting the distance between the two rollers, pipes of different sizes can be conveyed.
