Technical Field

The invention relates to the technical field of connection of a main sheet and a water chamber of automobile warm air, in particular to a brazing type engagement device for the side edge of the main sheet.

background

The automobile warm air blower is a component of an automobile air conditioning system, is an automobile part for heating by utilizing cooling water of an automobile engine, and adopts a brazing mode in a production process. One of the core part of car warm braw is the warm braw core, comprises warm braw core main part and two hydroeciums, and the warm braw core structure is complicated and require strict sealing, in actual production process, places the warm braw core in a support frame usually, bends the tooth piece of four sides of electric fan heater main leaf through the incision sword, makes four sides of hydroecium buckle with four sides of main leaf accurately.

disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a device for clamping the side edge of a brazed main sheet.

The purpose of the invention can be realized by the following technical scheme: a device for engaging the side edge of main sheet in brazing mode is composed of side stop blocks for clamping main sheet and water chamber, locating stop blocks for locating the main sheet and water chamber, and engaging knife for pushing and bending the side edge teeth of main sheet.

further, the side dog includes left side dog and right side dog, left side dog and right side dog are connected with the cylinder respectively.

Further, the occluding knife comprises a left occluding knife and a right occluding knife, and the left occluding knife and the right occluding knife are movably arranged on the left stopper and the right stopper respectively.

Further, the bottoms of the left side occluding knife and the right side occluding knife are respectively installed on the left side stop block and the right side stop block through slide rails.

Further, the location dog includes connecting portion and conflict portion, the one end of connecting portion is fixed on the dog of right side, and its other end passes through the detachable bolt and installs on the dog of left side, the conflict position is in the intermediate position of connecting portion, the conflict portion is inconsistent with the long side of main leaf.

Further, the location dog includes connecting portion and conflict portion, the one end of connecting portion is fixed on the dog of left side, and its other end passes through the detachable bolt and installs on the dog of right side, the conflict position is in the intermediate position of connecting portion, the conflict portion is inconsistent with the long side of main leaf.

Furthermore, the edge of the knife edge of the meshing knife is provided with an inclination angle, so that the side edge of the main sheet after meshing can be more attached to the side edge of the water chamber.

Furthermore, two sides of the knife edge of the occlusion knife are provided with rounded corners so as to reduce the stress of four rounded corners of the main sheet.

further, the inclination angle is 70-80 degrees.

Compared with the prior art, the invention has the following advantages:

Firstly, the main sheet and the water chamber can be effectively clamped and positioned through the side stop block and the positioning stop block, so that the meshing knife can be ensured to accurately bend the tooth sheet on the side edge of the main sheet, and the size deviation of a product is reduced.

According to the invention, the bevel angle is arranged at the edge of the meshing knife, so that the bevel angle is formed when the meshing knife bends the tooth sheet at the side edge of the main sheet, and the attaching degree of the side edge of the main sheet and the side edge of the water chamber during meshing can be improved.

And thirdly, the rounded corners are arranged on the two sides of the knife edge of the occluding knife, so that the stress of the four rounded corners of the main sheet is reduced when the occluding knife bends the tooth sheet on the side edge of the main sheet, and the problem of stacking and cracking caused by overlarge stress of the four rounded corners of the main sheet is solved.
