Automatic flattening machine for aluminum pipe of positive temperature coefficient (PTC) heater

Abstract

The invention discloses an automatic flattening machine for an aluminum pipe of a positive temperature coefficient (PTC) heater and belongs to the technical field of automated machines. The automatic flattening machine comprises a working platform, a pipe placing platform, aluminum pipe clamping and placing mechanisms, a left supporting platen, a right supporting platen, an aluminum pipe left end anti-deformation positioning protective mechanism, an aluminum pipe right end anti-deformation positioning protective mechanism, a pair of left flattening mechanisms and a pair of right flattening mechanisms, wherein the working platform is provided with a front adjusting threaded rod and a back adjusting threaded rod; the pipe placing platform is fixed to the middle of the working platform; the aluminum pipe clamping and placing mechanisms are arranged on the working platform; the front end and the back end of the left supporting platen are supported at the left end of the front adjusting threaded rod and the left end of the back adjusting threaded rod correspondingly, and the middle of the left supporting platen is matched with the left end of a supporting platen front guide rail and the left end of a supporting platen back guide rail; the front end and the back end of the right supporting platen are supported at the right end of the front adjusting threaded rod and the right end of the back adjusting threaded rod correspondingly, and the right supporting platen is matched with the right end of the supporting platen front guide rail and the right end of the supporting platen back guide rail at the same time; the aluminum pipe left end anti-deformation positioning protective mechanism is arranged on the left supporting platen; the aluminum pipe right end anti-deformation positioning protective mechanism is arranged on the right supporting platen; the left flattening mechanisms are arranged on the left supporting platen; and the right flattening mechanisms are arranged on the right supporting platen. According to the automatic flattening machine for the aluminum pipe of the PTC heater, the labor intensity is relieved, the flattening efficiency is high, and aluminum pipe cavity deformation caused in the flattening process is avoided; the human input is reduced, and safety is reflected.

Description

technical field [0001] The invention belongs to the technical field of automatic machinery, and in particular relates to an automatic dotting machine for an aluminum tube of a PTC heater. Background technique [0002] The above-mentioned aluminum pipe is the heat dissipation pipe, and because its material is aluminum, it is also called heat dissipation aluminum pipe. The aforementioned PTC is an abbreviation in English (English: Positive Temperature Coefficient), and its full name in Chinese is Positive Temperature Coefficient. The PTC heater is mainly composed of the following two parts: one is the heating element, which is also called the radiator; the other is the PTC heating core. The heating body includes an aluminum tube and a heat dissipation aluminum sheet positioned on the upper side surface and the lower side surface in the length direction of the aluminum tube and having a corrugated structure. The PTC heating core is accommodated in the aluminum tube cavity of ...

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 (anvil) at the port of the aluminum lumen and at the position corresponding to the dotting, and remove the lining block after the dotting is completed, so that It aggravates the work intensity of the workers and then reduces the work efficiency; Fourth, due to the low efficiency of manual management, more manpower needs to be invested, thereby causing a waste of valuable labor resources and increasing the cost of PTC heater manufacturers. labor cost; 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; At the same time, the fingers touch the aluminum tube, and the other hand holds a hammer or similar utensils, so if you are not careful, you will hurt your limbs (fingers)
