Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a PTC heater processing workbench. Background Art

[0002] With the active adoption of advanced parallel flow circulation technology in the automotive air-conditioning industry, the heat dissipation efficiency of aluminum water tanks and radiators has been greatly improved, so they are fully utilized in the condenser and evaporator of the automotive air-conditioning system. It is an inevitable trend for the automotive water tank and intercooler to be made of all-aluminum materials. The refrigerant in the heat exchanger used in the current air-conditioning system is mainly circulated through the microchannel aluminum flat tubes of the heat exchanger, so the aluminum flat tube is an indispensable part of the automotive air-conditioning PTC heater.

[0003] After searching, the Chinese patent publication number CN215034024U discloses an aluminum flat tube cutting device for the production and processing of automobile air-conditioning PTC heaters, including a workbench and a mounting frame installed on the top of the workbench, the workbench is rotated by a mounting groove opened on the top of the workbench and is matched with a horizontally arranged square rotating shaft, a turntable is installed on the surface of the square rotating shaft, two symmetrical short supporting flat bars located on the same meridian of the turntable are installed on the surface of the turntable, each of the short supporting flat bars is slidably matched with a slide seat, the slide seat is clamped with an iron baffle through a clamping groove opened on the surface of the slide seat, and the top of the workbench is sequentially installed with driving squares from left to right. The invention comprises a rotation adjustment mechanism for rotating the shaped rotating shaft, a horizontal adjustment component for driving the slide to move in the horizontal direction, and a support seat. The support seat is rotatably matched with a plurality of rollers distributed side by side through a through slot provided at the top of the support seat. A cutting mechanism for cutting the aluminum flat tube is installed on the upper side of the support seat. The inner side wall of the mounting frame is rotatably matched with a horizontally arranged main lead screw, and one end of the main lead screw is connected to the driving end of the third stepper motor installed on the side wall of the mounting frame. The main drive seat is threadedly connected to the surface of the main lead screw. The main drive seat is installed with a pressure plate through an inclined rod installed at the bottom end of the main drive seat. A feeding mechanism for feeding the cut aluminum flat tube is installed on the inner side of the workbench. The above patent has the following shortcomings: Although the patent can cut and process the aluminum flat tubes in the PTC heater of the automobile air conditioner, it can only cut one aluminum flat tube at a time, so the processing efficiency needs to be improved. In view of this, we propose a PTC heater processing workbench. Utility Model Content
