[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a heating type punching device for the flow channel of chrome-plated parts of automobile air outlets comprises a punching box 10 and an air outlet frame 60. The air outlet frame 60 can replace other automobile parts. The interior of the punching box 10 is sequentially installed with a recovery mechanism 50, a punching mechanism 20, a fixing mechanism 30 and a lifting mechanism 40 from bottom to top. The air outlet frame 60 is placed between the punching mechanism 20 and the fixing mechanism 30. The lifting mechanism 40 is connected to the fixing mechanism 30 in a transmission manner for controlling the movement of the fixing mechanism 30 to fix the air outlet frame 60, so as to prevent the air outlet frame 60 from popping out when the punching mechanism 20 is punching.

[0034] Specifically, two mirror-image start buttons are installed on the outside of the punching machine box 10. After the operator inputs the preset parameters and the air pressure and temperature rise to the set values, the air outlet frame 60 is placed in the punching tool 211. The punching tool 211 adopts a contoured design so that it can be fully matched with the air outlet frame 60. Then the operator presses the two start buttons with both hands at the same time, and the lifting mechanism 40 drives the fixing mechanism 30 to fix the air outlet frame 60, and the punching mechanism 20 punches the water outlet 61 of the air outlet frame 60. Finally, the recovery mechanism 50 recovers the punched water outlet 61.

[0035] like Figure 3 and Figure 4 As shown, the punching mechanism 20 includes a base 21, a punching tool 211 is installed on one side of the base 21 through a side plate 25, the air outlet frame 60 is placed in the punching tool 211, a cylinder 26 is fixedly installed on the inner ring of the side plate 25, a push plate 27 is fixedly connected to the output end of the cylinder 26, a side of the push plate 27 away from the base 21 is connected to a partition 29 through an electric heater 28, and a plurality of punching knives 210 are installed on the side of the partition 29 close to the punching tool 211.

[0036] It should be noted that the two side panels 25 are mirror-imaged, and two side panels 1 23 are installed between the two side panels 25. A rectangular frame is formed by the two side panels 1 23 and the side panels 25. At the same time, the side panels 1 23 are provided with heat dissipation holes 24 for ventilation and heat dissipation. The electric heater 28 uses electric heating to heat the punching cutter 210. When the temperature is reached, the cylinder 1 26 drives the punching cutter 210 to approach the air outlet frame 60 to punch the water outlet 61 of the air outlet frame 60. By continuously heating the punching cutter 210, it can be ensured that there is no material debris at the punching location and the blade is neat.

[0037] like Figure 4 As shown, a slide rail 212 and a slider 213 are fixedly connected to the base 21 and the push plate 27 at one side close to each other, and the slide rail 212 and the slider 213 are slidably matched.

[0038] It should be noted that, through the sliding cooperation between the slide rail 212 and the slider 213, the cylinder 26 can move smoothly while driving the push plate 27 to move, thereby ensuring that the punching knife 210 can smoothly punch the water outlet 61 off the air outlet frame 60 to avoid gaps.

[0039] like Figure 4 As shown, the push plate 27 and the partition 29 are both made of heat-insulating material, the partition 29 is provided with a through hole, a heat conduction rod is fixedly installed on one side of the punching knife 210, and the end of the heat conduction rod contacts the electric heater 28.

[0040] Specifically, the heat insulating material is made of any one of glass fiber, asbestos, rock wool, silicate, etc., and the heat conduction rod is made of any one of copper, aluminum, tungsten, graphite, etc. The push plate 27 and the partition 29 can prevent the electric heater 28 from causing high temperature damage to other components. The electric heater 28 continuously heats the punching knife 210 through the heat conduction rod, so that the cylinder 26 can easily push the punching knife 210 to punch the water outlet 61.

[0041] Example 2

[0042] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the heating type punching device for the flow channel of the chrome-plated parts of the automobile air outlet, compared with the embodiment 1, the fixing mechanism 30 of this embodiment includes a cylinder 2 31, the cylinder 2 31 is connected to the lifting mechanism 40, and the output end of the cylinder 2 31 is fixedly installed with a connecting block 32, and a detachable baffle 33 is installed on the side of the connecting block 32 away from the cylinder 2 31, and the baffle 33 is located above the air outlet frame 60, and is used to protect the air outlet frame 60 during the punching process.

[0043] Specifically, when the lifting mechanism 40 drives the cylinder 2 31, the connecting block 32 and the blocking knife 33 to approach the air outlet frame 60, the cylinder 2 31 drives the blocking knife 33 to move to the connection between the air outlet frame 60 and the water outlet 61 through the connecting block 32, so that the end of the blocking knife 33 is against the connection, thereby preventing the punching tool 211 from causing damage to the air outlet frame 60 itself due to excessive force.

[0044] like Figure 1 , Figure 2 and Figure 5 As shown, the lifting mechanism 40 includes a cylinder three 41, which is installed in the top inner circle of the punching machine box 10, and the output end of the cylinder three 41 is fixedly connected to a lifting seat 43 through a connecting seat 42. The lifting seat 43 is equipped with a plurality of detachable cylinder seats 45, and the cylinder seat 45 is connected to the cylinder two 31.

[0045] Specifically, after being started, the cylinder three 41 can drive the lifting seat 43 to move up and down inside the punching machine box 10 through the connecting seat 42, and the lifting seat 43 can drive the cylinder two 31 and the structure connected thereto to move together through the cylinder seat 45.

[0046] like Figure 2 As shown, the inner ring of the lifting seat 43 is fixedly sleeved with a sliding sleeve 44 , and the sliding sleeve 44 is movably sleeved on the column inside the punching machine box 10 .

[0047] It should be noted that, through the cooperation between the sliding sleeve 44 and the column, the lifting seat 43 will not shake during the movement, thereby increasing the overall stability of the fixing mechanism 30 .

[0048] like Figure 5 As shown, the fixing mechanism 30 further includes a pressing plate 34 , which is connected to the lifting seat 43 via bolts 35 , and a through opening is formed in the pressing plate 34 , through which the knife block 33 passes.

[0049] Specifically, the pressure plate 34 can move along with the lifting seat 43 through the bolts 35. The lifting seat 43 and the pressure plate 34 are located on the top of the punching chassis 10 before punching. When the air outlet frame 60 is placed in the punching tool 211 and the two start buttons are pressed, the cylinder three 41 will push the pressure plate 34 to contact the punching tool 211, completely cover the air outlet frame 60, and fix it.

[0050] Example 3

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heating type punching device for the flow channel of chrome-plated parts of automobile air outlets proposed by the present invention, compared with embodiment 1 or embodiment 2, the recovery mechanism 50 of this embodiment includes a recovery box 51, and the recovery box 51 is placed on the shell of the punching machine box 10 located below the base 21, and the base 21 is provided with a discharge port 22. Support plates 53 fixedly connected to the punching machine box 10 are arranged on both sides of the recovery box 51, and the support plates 53 are plugged into the base 21, and a handle 52 is fixedly installed on the outer wall of the recovery box 51.

[0052] Specifically, after the cylinder 26 controls the punching knife 210 to punch the water outlet 61, the water outlet 61 will pass through the discharge port 22 between the two pairs of mirror-arranged push plates 27, the electric heater 28 and the partition 29 and fall into the interior of the recovery box 51. The water outlet 61 that falls after punching can be collected by the recovery box 51, and finally the recovery box 51 can be pulled out from the bottom of the base 21 by pulling the handle 52 to process the internal water outlet 61.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
