[0001] The utility model relates to the field of radiators, in particular to a one-time pressing tool for aluminum radiators. Background Art

[0002] The radiator comprises an upper water chamber and a radiator core, and the upper water chamber is formed by an upper cover being pressed and sealed on the upper end of the radiator core.

[0003] The Chinese patent with the announcement number CN215879560U discloses a car radiator water chamber crimping machine, including a frame, a side crimping component, a rear end crimping component and a pressing and fixing component. The frame includes two spaced mounting platforms and a top frame. The side crimping components have two groups, which are respectively mounted on the two mounting platforms, spaced parallel and relatively arranged. The side crimping components include four crimping mechanisms; the rear end crimping component is mounted on the mounting platform and is located at the spaced terminal of the two groups of side crimping components. The rear end crimping component includes a crimping mechanism; the front end crimping component is mounted on the mounting platform. The front end crimping component includes a crimping mechanism and a driveable The clamping mechanism in the front end clamping component is close to or away from the interval starting point of the two groups of side clamping components; the clamping mechanism includes a base, a side plate clamping block, a clamping assembly and a driving assembly, the base is installed on the mounting platform, the side plate clamping block is installed on the base through a first horizontal track, a clamping head is provided at one end of the side plate clamping block close to the side clamping component, the clamping assembly includes a movable plate installed on the side plate clamping block through a second horizontal track and a clamping block hinged at the front end of the movable plate, a clamping head is provided at the front end of the clamping block, and the driving assembly includes a pushing block provided below the rear end of the clamping block and a cylinder that drives the pushing block to reciprocate up and down.

[0004] When producing the radiator in the above structure, the automobile radiator is first placed between the two sets of side clamping parts, and then fixed by pressing the fixing parts. After that, each clamping mechanism is activated to bend the fasteners on the automobile radiator so that the fasteners can buckle the water chamber and the radiator core together. However, the above structure requires multiple clamping mechanisms when bending the fasteners to buckle the water chamber and the radiator core, which results in a higher production cost of the radiator. Utility Model Content

[0005] The utility model provides a one-time pressing tool for an aluminum radiator to address the disadvantages of the prior art that a plurality of pressing mechanisms are needed to bend the fasteners during the fastening process of the radiator core and the water chamber, thereby achieving the fastening between the radiator core and the water chamber, which leads to a high production cost of the radiator.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A one-time pressing tool for an aluminum radiator comprises a workbench, on which are arranged overlapping parts for partially overlapping a radiator core and limiting parts for fixing the radiator core when it is overlapped on the overlapping parts, a plurality of vertically upward locking teeth are arranged at intervals around the top of the radiator core, and a lifting part is arranged above the workbench, which is driven by a descending rear drive to synchronously bend all the locking teeth to seal and lock an upper cover to the upper end of the radiator core.

[0008] By adopting the above scheme, the provided lifting component can squeeze the locking teeth on the radiator core when it descends, so that the locking teeth are bent. When the locking teeth are bent, the upper cover will be sealed and pressed on the top of the radiator core. Since the sealing and locking between the radiator core and the upper cover only requires one lifting component to drive all the locking teeth on the radiator core to bend at the same time, the production cost of the radiator is reduced.

[0009] Preferably, the overlapping component comprises an overlapping block arranged on a workbench, wherein the overlapping block is provided with an overlapping groove for partial insertion of the radiator core, the top of the radiator core is overlapped with the top of the overlapping groove, and the overlapping groove and the radiator core are matched without gap.

[0010] By adopting the above scheme, the radiator core can be partially inserted into the overlapping groove provided on the overlapping block, and the top of the radiator core can also be overlapped on the top of the overlapping groove. By arranging the overlapping groove and the radiator core to be matched without gap, the probability of the radiator core slipping in the overlapping groove after being inserted into the overlapping groove can be reduced.

[0011] Preferably, one end of the lap groove is open, and the limiting component includes a limiting plate at one end of the lap groove opening and hinged to the lap groove opening, and a fixing component is provided between the limiting plate and the lap groove for fixing the position of the limiting plate when the limiting plate is flipped to close the lap groove opening.

[0012] By adopting the above scheme, an opening is set at one end of the lap groove so that the radiator core can be horizontally inserted into the lap groove, thereby reducing the required height between the lifting component and the lap block, and reducing the overall mechanical height. A limit plate hinged at one end of the lap groove opening can close the opening of the lap groove after the radiator core is inserted into the lap groove. At the same time, the limit plate can also fix the radiator core inserted into the lap groove. At this time, the lifting component can be used to buckle the radiator core and the upper cover.

[0013] Preferably, the fixing component includes a first screw hole arranged on one end of the limit plate away from its hinged end, a second screw hole arranged on the side wall of the overlapping block and having the same size as the first screw hole and directly opposite to the first screw hole when the limit plate is flipped over to cover the opening of the overlapping groove, and a middle threaded shaft that can be screwed into the second screw hole when the limit plate covers the opening of the overlapping groove.

[0014] By adopting the above scheme, the threaded shaft can be screwed from the first screw hole on the limit plate into the second screw hole on the overlap block when the limit plate is flipped to close the opening of the plug-in slot. At this time, the limit plate will be limited to maintain the state of closing the opening of the overlap slot. When the radiator core and the upper cover are fastened together, the threaded shaft can be rotated in the opposite direction to screw the threaded shaft out of the second screw hole. At this time, the radiator core can be taken out from the overlap slot.

[0015] Preferably, a rotating component is provided at the end of the threaded shaft away from its insertion end, which facilitates the user to screw the threaded shaft into the first screw hole and the second screw hole or to screw the threaded shaft out of the second screw hole. The rotating component includes a force rod which is provided at the threaded shaft away from its insertion end and extends upward and then bends horizontally.

[0016] By adopting the above scheme, the force rod is set to facilitate workers to rotate the threaded shaft. When the limit plate is flipped to close the opening of the overlap groove, the force rod can be used to screw the threaded shaft from the first screw hole into the second screw hole, thereby achieving the limit between the limit plate and the overlap block. At this time, the radiator core inserted into the overlap groove will be limited in the plug-in groove. At this time, the lifting component is lowered to bend the locking teeth on the radiator core, thereby achieving a sealed lock between the upper cover and the radiator core.

[0017] Preferably, the lifting component includes a lifting plate arranged above the overlapping component, a driving component arranged above the lifting plate for driving the lifting plate to lift and lower, and a plurality of extrusion blocks or extrusion plates arranged on the bottom surface of the lifting plate for extruding the locking teeth after being lowered, and a guide component for guiding the bending of the locking teeth is arranged at one end of the plurality of extrusion blocks or the extrusion plates away from the lifting plate.

[0018] Preferably, the driving component comprises a cylinder which is arranged above the lifting plate and has its protruding end facing vertically downward and fixed to the top surface of the lifting plate.

[0019] By adopting the above scheme, the cylinder arranged above the lifting plate can drive the lifting plate to move downward when the extending end thereof extends outward, so that the several extrusion blocks or extrusion plates on the lifting plate gradually approach the snap-fitting teeth arranged on the radiator core and squeeze the snap-fitting teeth after contacting the snap-fitting teeth, thereby bending the snap-fitting teeth to snap the upper cover with the radiator core. When the radiator core and the upper cover are snapped together, it is only necessary to use the cylinder to drive the lifting plate and the several extrusion blocks or extrusion plates on the lifting plate to move, so that the upper cover can be snapped onto the radiator core, thereby reducing the cost of radiator production.

[0020] Preferably, the guide component comprises a guide arc surface arranged at one end of the plurality of extrusion blocks or extrusion plates away from the lifting plate, and the guide arc surface increases in an arc shape from one end of the extrusion blocks or extrusion plates close to each other to one end away from each other.

[0021] By adopting the above scheme, the guide arc surface arranged on the end of the plurality of extrusion blocks or the extrusion plates away from the lifting plate can contact the end of the locking tooth when the driving component drives the lifting plate to descend, and gradually pressurizes the locking tooth to bend the locking tooth in the process of the driving component continuing to drive the lifting plate to descend, thereby sealing the upper cover and the radiator core.

[0022] Preferably, a sealing component is also provided on the upper cover for strengthening the seal between the upper cover and the radiator core when the locking teeth lock the upper cover and the radiator core.

[0023] Preferably, the sealing component includes a sealing ring arranged around the edges of the upper cover.

[0024] By adopting the above solution, when the lifting component drives the buckling teeth to bend, the sealing ring will be pressed between the upper cover and the buckling teeth, thereby improving the sealing performance between the upper cover and the radiator core.

[0025] The utility model adopts the above technical scheme, and has remarkable technical effects: the lifting component can squeeze the locking teeth on the radiator core when it descends, so that the locking teeth are bent, and when the locking teeth are bent, the upper cover will be sealed and pressed on the top of the radiator core. During the sealing and locking process between the radiator core and the upper cover, only one lifting component needs to be used to drive all the locking teeth on the radiator core to bend at the same time, thereby reducing the production cost of the radiator.
