Copper pipe port machining device

Abstract

The invention discloses a copper pipe port machining device. The copper pipe port machining device comprises a punch press, a core rod, an upper die and a lower die. The lower die is assembled on a die plate. The upper die and a die handle are assembled. The die handle is fixed with a punch press sliding rail through a sliding block die handle fixing device. A protruding wheel is assembled in a protruding wheel seat. One ends of a protruding wheel tension spring and the protruding wheel are fixed through screws. The other end of the protruding wheel tension spring is fixed on a lateral face of the punch press sliding rail through a protruding wheel tension spring fixing screw. One ends of a reset spring and a reset spring baffle are connected and fixed. The other end of the reset spring is connected with a material returning sliding block which is arranged in a material returning sliding block groove. The core rod is arranged on a connecting plate of the material returning sliding block and the core rod. The die adopts the protruding wheel mechanical structure to loose core and retreat die and uses the tension spring and the spring to reset, and saves external equipment of an air cylinder, a magnetic valve, a travel switch and the like. The copper pipe port machining device has the advantages that not only accessories cost can be saved, but also air and electricity cost in subsequent use can be saved, after configuration is reduced, failure efficiency is reduced, and thus production efficiency is improved.

Description

[0001] Technical field: [0002] The invention relates to a copper pipe port processing device, which is especially suitable for branching processing of pipe ports in air-conditioning pipeline parts. Background technique: [0003] At present, when the pipe ports in the air-conditioning pipeline parts are branched and processed in the industry, punching is used to form them (see figure 1 with figure 2 ), when working, put the product to be processed into the mandrel 9, the foot switch 6, the punch press starts, the punch press slides to drive the die handle 12 and the upper die 11 to move down, and when they move down to the lower limit, the upper die 11 and the lower die 7 match, and the stamping product is formed. At this time, the product is closely matched with the mandrel 9, and it is difficult to take it out. At this time, the upper mold 11 moves upward, and at the same time, the eccentric wheel 3 rotates to the position of the limit switch 4, and the solenoid val...

Problems solved by technology

[0003] At present, when the pipe ports in the air-conditioning pipeline parts are branched and processed in the industry, punching is used to form them (see figure 1 and figure 2 ), when working, put the product to be processed into the mandrel 9, the foot switch 6, the punch press starts, the punch press slides to drive the die handle 12 and the upper die 11 to move down, and when they move down to the lower limit, the upper die 11 and the lower die 7 match, and the stamping product is formed. At this time, the product and the mandrel 9 are tightly matched, and it is difficult to take it out. At this time, the upper mold 11 moves upward, and at the same time, the eccentric wheel 3 rotates to the position of the limit switch 4, and the solenoid valve 5 is turned on. After the valve reverses, start the cylinder 10 fixed on the connection plate 8, the cylinder works to drive the cylinder and the mandrel 9 to move backward, complete the core pulling and ejection, and take out the product easily. position, the eccentric wheel continues to rotate, leave the travel switch 4, the solenoid valve 5 is powered off and resets, the cylinder connecting plate and mandrel are reset, and are ready for the next work. The disadvantage is that the stamping equipment needs to add solenoid valves, cylinders, travel switches, etc. To set up the equipment, an air pump is also required, which is not only expensive, but also the combination of gas and electricity is prone to failure, which affects production
