Aluminum tube automatic dotting machine

Abstract

The invention discloses an automatic dotting machine for an aluminum pipe, and belongs to the technical field of automatic machines. The automatic dotting machine for the aluminum pipe comprises a work platform, a pipe holding platform, a left supporting platform plate, a right supporting platform plate, an aluminum pipe left end anti-deformation positioning protective mechanism, an aluminum pipe right end anti-deformation positioning protective mechanism, a pair of left dotting mechanisms and a pair of right dotting mechanisms, wherein the work platform is provided with a front adjustment screw and a rear adjustment screw, and a supporting platform plate front guide rail and a supporting platform plate rear guide rail are fixed to the work platform; the pipe holding platform is arranged in the middle of the work platform; the front end of the left supporting platform plate is supported at the left end of the front adjustment screw, the rear end of the left supporting platform plate is supported at the left end of the rear adjustment screw, and the middle of the left supporting platform plate is matched with the left ends of the supporting platform plate front guide rail and the supporting platform plate rear guide rail; the front end of the right supporting platform plate is supported at the right end of the front adjustment screw, the rear end of the right supporting platform plate is supported at the right end of the rear adjustment screw, and the middle of the right supporting platform plate is matched with the right ends of the supporting platform plate front guide rail and the supporting platform plate rear guide rail; the aluminum pipe left end anti-deformation positioning protective mechanism is arranged in the middle of the left supporting platform plate; the aluminum pipe right end anti-deformation positioning protective mechanism is arranged in the middle of the right supporting platform plate; the pair of left dotting mechanisms are arranged on the left supporting platform plate; and the pair of right dotting mechanisms are arranged on the right supporting platform plate. The automatic dotting machine for the aluminum pipe relives labor intensity, is high in dotting efficiency and good in quality, avoids deformation of a pipe cavity of the aluminum pipe in the dotting process, and saves resources.

Description

technical field [0001] The invention belongs to the technical field of automatic machinery, and in particular relates to an automatic dotting machine for aluminum tubes, which is used to form dots on the aluminum tubes of PTC heaters and at the positions corresponding to the two ends of the heat-dissipating aluminum sheets embedded in the aluminum tubes. The deformation block is used to prevent the heat dissipation aluminum sheet from moving. Background technique [0002] The aforementioned aluminum tube is the heat dissipation tube, and because its material is aluminum, it is also called the heat dissipation aluminum tube (the same below); the aforementioned heat dissipation aluminum sheet is the heat dissipation aluminum strip (the same below); the aforementioned PTC is the abbreviation of English (English: PositiveTemperature Coefficient), Chinese full name is positive temperature coefficient (hereinafter the same). The PTC heater is mainly composed of the following two ...

Problems solved by technology

[0007] Although the above-mentioned hitting on the upper protrusion and the lower protrusion of the aluminum tube (i.e. the aforementioned dots) can prevent the two pieces (i.e. two 1) The purpose of the swaying of the heat dissipation aluminum sheet, but there are the following technical problems: one, because the dot is completed by the online operator in a manual manner, so the labor intensity of the workman is large; For the aluminum tube of two heat-dissipating aluminum sheets, it needs to be dotted eight times, so the work efficiency is low; third, in order to avoid the deformation of the aluminum tube cavity of the aluminum tube due to excessive force during dotting, it will affect the follow-up process. The heating core is introduced into the aluminum lumen, so it is necessary to insert a plug-shaped lining block at the port of the aluminum lumen and at the position corresponding to the dotting, and the lining block acts as a cutting board, and then remove it after the dotting is completed. Lining block, thus intensifying the work intensity of workers and reducing work efficiency; Fourth, due to the low efficiency of manual dotting, more manpower needs to be invested, resulting in a waste of valuable labor resources and increasing the PTC The labor wage cost of the heater manufacturer; fifth, the quality of the management is difficult to guarantee, because the quality of the management is often related to the worker's sense of responsibility, emotion, experience and physical fitness; Hold a blunt chisel and at the same time touch the aluminum tube with your fingers, and hold a hammer or similar utensil in the other hand, so if you are not careful, you will hurt your limbs (fingers)
