[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] Example 1

[0039] refer to Figure 1-10 The radiator crimping machine with all-round crimping includes a frame 1, a core supporting device, a water chamber clamping device and a crimping device.

A slide rail 25 is horizontally arranged on the frame 1. The core support frame includes a fixed frame 21 and a mobile frame 22 arranged in parallel and spaced apart. Both the fixed frame 21 and the mobile frame 22 have a core accommodating opening. The height of the accommodating opening is greater than the thickness of the core and less than the thickness of the main board. A slider 221 is provided at the bottom of the mobile frame 22. The slider 221 is adapted to the slide rail 25. The mobile frame 22 can move horizontally along the slide rail 25 under the drive of the fourth motor 23 and the gear rack transmission mechanism 24.

[0041] There are two groups of water chamber clamp devices, which are arranged oppositely on the left and right sides of the core support device.

[0042] The water chamber clamp device comprises a clamp cavity 31, a clamping mechanism and a clamp driving mechanism. The clamp cavity 31 is arranged transversely and has front and rear end openings and a side opening.

[0043] The clamping mechanism comprises a front and rear clamping mechanism, an upper and lower clamping mechanism and a side opening clamping mechanism for clamping the water chamber.

[0044] The front and rear clamping mechanisms are clamping plates 32 arranged at the front and rear ends of the clamp cavity 31; the clamping plates 32 have a bent connection portion; mounting holes are arranged at intervals on the back plate 311 of the clamp cavity 31, and the bent connection portion is connected to the back plate 311 of the clamp cavity 31 through the mounting holes using fasteners.

[0045] A plurality of mounting grooves are provided at intervals on the clamp cavity 31, and the upper and lower clamping mechanisms include a plurality of clamping block assemblies provided on the mounting grooves; the clamping block assemblies include a cylinder 33, a rotating shaft 35 and a movable block 34; the cylinder 33 is provided below the mounting groove, and the middle part of the movable block 34 is movably installed in the mounting groove of the clamp cavity 31 through the rotating shaft 35, the piston rod of the cylinder 33 is opposite to the inner end of the movable block 34, and the outer end of the movable block 34 is a pressing head.

[0046] The side opening clamping mechanism includes two groups of side opening clamping components symmetrically arranged on the front and rear sides of the clamp cavity 31. The side opening clamping components include a clamping plate 32 and a clamping plate 32 driving device connected to the clamping plate 32. The clamping plate 32 can clamp the side openings at the front and rear ends of the clamp cavity 31 under the drive of the clamping plate 32 driving device.

[0047] The driving device of the clamping plate 32 includes a first slide cylinder 36, a second slide cylinder 37 and a guide block 38. The first slide cylinder 36 is arranged on the frame 1 and is located on the outside of the clamping plate 32. The guide block 38 is installed at the end of the first slide 361 of the first slide cylinder 36. The guide block 38 is provided with a guide hole 381. The second slide cylinder 37 is installed on the side of the first slide 361 of the first slide cylinder 36. One section of the clamping plate 32 is connected to the side of the second slide 371 of the second slide cylinder 37, and the other section of the clamping plate 32 corresponds to the position of the guide hole 381.

[0048] The clamp driving mechanism is used to drive the clamp cavity 31 and the clamping mechanism to approach the core support device or move away from the core support device; the clamp driving mechanism includes a first motor 41, a screw nut pair 42 and a linkage frame 43. The linkage frame 43 moves laterally under the drive of the first motor 41 and the screw nut pair 42. The linkage frame 43 is connected to the clamp cavity 31 (specifically, the back plate 311 of the clamp cavity 31).

[0049] There are two groups of buckling devices, which are arranged oppositely on the left and right sides of the core support device; the buckling device includes a transverse driving mechanism arranged on the frame 1 and two groups of buckling mechanisms symmetrically arranged on the upper and lower sides.

[0050] The crimping mechanism includes a connecting plate 61, a crimping head 62, and a vertical crimping drive assembly connected to the crimping head 62; the crimping head 62 and the vertical crimping drive assembly are both mounted on the connecting plate 61, and the connecting plate 61 is connected to the transverse drive mechanism, which drives the crimping mechanism to move transversely. Specifically, the transverse drive mechanism includes a second motor 51, a transmission assembly 52, a screw rod 53, a nut seat 54, and a connecting frame 55. The second motor 51 is driven and connected to the screw rod 53 through the transmission assembly 52 (which may be a gear chain transmission assembly), the nut seat 54 is adapted to be connected to the screw rod 53, and the connecting frame 55 is connected to the nut seat 54. The connecting frame 55 is a side U-shaped, and the two open ends of the connecting frame 55 are respectively connected to the connecting plates 61 of the two sets of crimping mechanisms.

[0051] The vertical crimping drive assembly drives the crimping head 62 to reciprocate up and down. The vertical crimping drive assembly includes a third motor 63 and an eccentric wheel transmission mechanism 64 connected to the third motor 63. The eccentric wheel transmission mechanism 64 is connected to the crimping head 62. The third motor 63 drives the crimping head 62 to reciprocate up and down through the eccentric wheel transmission mechanism 64.

[0052] The workflow of the present invention is as follows:

[0053] The movable frame 22 of the core supporting device is driven by the fourth motor 23 and the gear rack transmission mechanism 24 to approach the fixed frame 21 by a certain distance, and then the radiator core connected with the main board and the side plate is inserted into the accommodating openings of the fixed frame 21 and the movable frame 22. Then, the movable frame 22 is driven by the fourth motor 23 and the gear rack transmission mechanism 24 to translate a certain distance in the direction away from the fixed frame 21, so that the movable frame 22 is against the main board, thereby fixing the core.

[0054] Adjust the position of the clamp 32 according to the length of the water chamber, then put the water chamber into the clamp cavity 31, the piston rod of the cylinder 33 of the upper and lower clamping mechanism is pushed upward, the rear end of the movable pressure block 34 is tilted, and the front end is pressed downward, thereby pressing the water chamber downward.

[0055] The end of the first slide 361 of the first slide cylinder 36 of the side-opening clamping mechanism extends outward to a suitable position, and then the second slide 371 of the second slide cylinder 37 moves toward the center of the water chamber, thereby driving the clamping plate 32 to pass through the guide hole 381 to limit and fix the left and right ends of the water chamber.

[0056] The clamp cavity 31 and the clamping mechanism are driven by the clamp driving mechanism to approach the core support device. When the water chamber is about to approach the main board, the second slide cylinder 37 of the side opening clamping mechanism retreats, and then the first slide cylinder 36 retreats, and then the entire side opening clamping mechanism retreats (so that there is no interference when the water chamber approaches the main board). Then the water chamber further approaches the main board and docks with the main board, and the clamp driving mechanism stops driving.

[0057] Then, the crimping mechanism is driven to move horizontally by the horizontal driving mechanism, and the crimping head 62 is driven to perform a reciprocating crimping action up and down by the vertical crimping driving assembly. Thus, the radiator main board and the water chamber of the radiator can be crimped in all directions (the main boards on both sides and the upper and lower sides of the water chamber are crimped at the same time), with high automation and high work efficiency.

[0058] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
