The typical approach is to connect a section of circular pipe to the round side of the round-shaped connector to connect to another circular pipe. However, there is currently no specialized mold structure for connecting circular pipes to the round side of the round-shaped connector. Utility Model Content

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0025] Example: Figure 1-7As shown, the utility model is a mold pushing mechanism for converting linear motion into lateral motion, including a positioning block 1, and a moving block 2 that moves laterally along the positioning block 1, and the two end portions of the moving block 2 are respectively installed with a ribbed mold 3 and an auxiliary mold 4, and the positioning block 1 is installed with a forward-pushing push rod 5, and a pushing mechanism is provided between the push rod 5 and the moving block 2, and the pushing mechanism is used to push the moving block 2 to move laterally outward when the push rod 3 is pushed forward, and a hollow rotating tube 6 is fixed to the outside of the positioning block 1, and the push rod 5 passes through the rotating tube 6. The pushing mechanism pushes the moving block 2 to move laterally outward, causing the embossing mold 3 and the auxiliary mold 4 to move outward, wherein the embossing mold 3 and the auxiliary mold 4 are arranged at both ends of the moving block 2. When the auxiliary mold moves laterally outward, it pushes the square flange to move toward the cylinder. The machine body 14 is also provided with a driving mechanism that drives the key sleeve 10 to rotate, so that the push rod 5 can be driven to rotate and the square flange and the cylinder can be pressed tightly. When the embossing mold 3 moves laterally outward, the square flange and the cylinder will be embossed and formed at the same time after pressing, thereby tightly connecting the square flange and the cylinder, making the connection between the square flange and the cylinder simpler.

[0026] The pushing mechanism includes a push block 7 disposed at the front end of the push rod 5, and horizontal guide rails 13 are provided on both sides of the push block 7. The front end of the horizontal guide rail 13 is provided with an inclined guide rail 8. The movable block 2 is provided with a pair of pins 9, and a limiting cavity is formed between the pins 9 for the horizontal guide rails 13 and the inclined guide rails 8 to pass through. In the process of pushing the push rod forward, the movable block 2 is pushed laterally outward under the cooperation of the pins and the inclined guide rails, thereby causing the beading die 3 and the auxiliary mold 4 to move outward. When the auxiliary mold moves laterally outward, the flange is pushed toward the cylinder. The body 14 is also provided with a driving mechanism that drives the key sleeve 10 to rotate, thereby driving the push rod 5 to rotate and achieve the compression of the flange and cylinder. When the beading die 3 moves laterally outward, the flange and cylinder are simultaneously beaded, thereby tightly connecting the flange and cylinder, making the connection between the flange and cylinder easier.

[0027] The moving block 2 is provided with a socket for inserting the pin shaft 9 , and the pin shaft 9 is interference fit with the socket, which is convenient for installation.

[0028] Among them, the end of the push rod 5 is provided with a key shaft 10, and the outer sleeve of the key shaft 10 is provided with a key shaft sleeve 11, and the key shaft sleeve 11 is fixed to the machine body 14 through a bearing and a fixing frame 12. The machine body 14 is also provided with a driving mechanism for driving the key shaft sleeve 11 to rotate, which makes it convenient to drive the push rod to rotate, so that the embossing mold 3 and the auxiliary mold 4 can rotate.

[0029] Among them, the end of the push rod 5 is provided with a key shaft 10, and the outer side of the key shaft 10 is provided with a key shaft sleeve 11, and the key shaft sleeve 11 is fixed to the body 14 through a bearing and a fixing frame 12. The rotating tube 6 is fixedly set at the front end of the key shaft sleeve 11, so that the push rod can still be pushed forward when it rotates.

[0030] The machine body 14 is further provided with a driving mechanism for driving the key shaft sleeve 11 to rotate.

[0031] Among them, the machine body is also provided with a positioning plate 17 that cooperates with the rib embossing mold 3 and the auxiliary mold 4 and positions the round side of the circular pipe and the HVAC pipe. The positioning plate 17 is provided with a positioning hole 18, and the inner wall of the positioning hole 18 is provided with a clamping groove 19. The inner wall of the positioning plate is provided with multiple positioning frames for positioning the round side of the circular pipe and the HVAC pipe.

[0032] When working, this linear motion is converted into a transverse motion mold pushing mechanism. When in use, first put the circular side of the docked HVAC pipe and the circular pipe into the positioning hole for positioning, and then use the telescopic cylinder to push the front end of the key shaft 10, so as to drive the push rod 5 to push forward. When the push rod 5 is pushed forward, the pushing mechanism pushes the moving block 2 to move laterally outward, so that the embossing mold 3 and the auxiliary mold 4 move outward. The embossing mold 3 and the auxiliary mold 4 are arranged at both ends of the moving block 2. When the auxiliary mold moves laterally outward, it pushes the round flange to move toward the cylinder. The machine body 14 is also provided with a driving mechanism that drives the key shaft sleeve 10 to rotate, which can drive the push rod 5 to rotate and realize the compression of the round flange and the cylinder; when the embossing mold 3 moves laterally outward, it will simultaneously perform embossing on the compressed round flange and cylinder, thereby tightly connecting the round flange and the cylinder; making the connection between the round flange and the cylinder simpler. In addition, in the utility model, a key shaft 10 is provided at the end of the push rod 5, and a key shaft sleeve 10 is provided on the outer side of the key shaft 10. A driving mechanism for driving the key shaft sleeve to rotate is also provided on the body 14, which can drive the push rod 5 to rotate, so that it is convenient to perform rib forming on the round flange and the cylinder, wherein the front end of the key shaft 10 is pushed by the telescopic cylinder, thereby driving the push rod 5 to push forward.
