Description

Technical Field

[0001] The utility model belongs to the technical field of cold forging machines, and in particular relates to a cold forging machine for a PCB board radiator used for lamps. Background Art

[0002] The cold forging machine for PCB heat sinks for lighting fixtures is a key piece of equipment used in the production of these components. Through the cold forging process, the machine transforms raw metal into heat sink components with a specific shape and structure. This process significantly improves the heat dissipation performance and structural strength of the heat sink while maintaining a low manufacturing cost.

[0003] Cold forging is a process that applies pressure to metal materials at room temperature or lower, causing them to plastically deform into the desired shape and size. In the production of PCB heat sinks for lighting fixtures, cold forging machines precisely control pressure, temperature, and die shape to gradually forge the metal raw material into the heat sink's complex structure. Existing cold forging machines suffer from the following problems during use:

[0004] When using existing cold forging machines, the PCB board heat sink raw material is first placed into the machined hole on the upper surface of the cold pressing lower die. Then the stamping mechanism drives the cold pressing upper die downward to cold press the PCB board heat sink raw material. Currently, loading the material requires manual operation, which is not only slow but also dangerous. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a cold pressing forging machine for PCB board heat sinks for lamps. The cold pressing forging machine is designed to solve the technical problem that the existing technology requires manual loading, which is not only slow but also dangerous.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the utility model provides a cold press forging machine for PCB board heat sinks for lamps, which includes a forging machine base, a punching mechanism, a cold press lower die, and a cold press upper die. The punching mechanism is installed on the upper surface of the forging machine base, the cold press lower die is installed on the upper surface of the forging machine base, and the cold press upper die is installed on the bottom side surface of the punching mechanism.

[0009] The upper surface of the forging machine base is connected to a bracket, the top of the bracket is connected to a cross frame, the surface of the cross frame is sleeved with a movable sleeve, the inner wall of the movable sleeve is connected to a guide slider, and a guide groove is provided on the surface of the cross frame near the guide slider. A bearing is installed inside the cross frame, and a threaded rod is connected to the inside of the bearing, and the threaded rod passes through the inside of the movable block. The upper surface of the movable block is connected to a feeding slide, and the surface of the feeding slide is connected to a storage bin, and a push plate is inserted into the inside of the feeding slide, and a first telescopic rod is installed between the push plate and the feeding slide.

[0010] When using the cold forging machine of the present technical solution, the servo motor can drive the movable sleeve to move horizontally through the threaded rod and the movable block when it is running. The horizontal movement of the movable sleeve can drive the feeding slide to move in the direction close to the cold pressing lower die. When the through hole at the end of the feeding slide is aligned with the material hole, the first telescopic rod is controlled to retract. When the first telescopic rod retracts, it can drive the pusher plate to move in the direction away from the feeding slide. When the pusher plate moves to the outside of the storage bin, the PCB board radiator raw material can fall into the feeding slide. Then, when the first telescopic rod is extended, the PCB board radiator raw material is squeezed by squeezing the pusher plate to move toward the through hole at the end. The PCB board radiator raw material can fall into the material hole through the through hole, thereby realizing automatic loading for cold pressing.

[0011] Preferably, the guide slider is slidably connected to the cross frame via the guide slot, and the movable sleeve is subjected to a force that can drive the guide slider to slide inside the guide slot, thereby limiting the movement direction of the movable sleeve.

[0012] Furthermore, a rotating structure is formed between the threaded rod and the bearing, and the threaded rod and the movable block are threadedly connected. The rotation of the threaded rod can drive the movable block to move through the threaded connection relationship, and the movement of the movable block can drive the loading slide to move, thereby adjusting the position of the loading slide.

[0013] Furthermore, a telescopic structure is formed between the push plate and the first telescopic rod, and a through hole matching the size of the PCB board radiator raw material is provided at the end of the loading slide. When the first telescopic rod is in operation, it can drive the push plate to move laterally, so that the PCB board radiator raw material can be pushed by the push plate.

[0014] Furthermore, the side surface of the cold pressing lower die is connected to a guide slide rail, the surface of the guide slide rail is sleeved with a sliding sleeve, the upper surface of the sliding sleeve is connected to a connecting block, the upper surface of the connecting block is installed with a pneumatic mechanical clamp, a second telescopic rod is installed between the guide slide rail and the connecting block, and the side surface of the cold pressing lower die is connected to a material guide trough.

[0015] Furthermore, a sliding connection is formed between the sliding sleeve and the guide rail, and the connecting block is subjected to a force so as to drive the sliding sleeve to slide on the surface of the guide rail, thereby limiting the movement direction of the connecting block.

[0016] Furthermore, a telescopic structure is formed between the connecting block and the second telescopic rod. The operation of the second telescopic rod can drive the pneumatic mechanical gripper to move horizontally through the connecting block, thereby adjusting the position of the pneumatic mechanical gripper.

[0017] Furthermore, the material guide trough is located directly below the pneumatic mechanical gripper. The model of the pneumatic mechanical gripper is J1060-DHVG. When the pneumatic mechanical gripper drives the PCB board heat sink to the entrance of the material guide trough, the pneumatic mechanical gripper is released to allow the PCB board heat sink to fall into the material guide trough, thereby realizing the collection of the PCB board heat sink after processing.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model can drive the movable sleeve to move horizontally through the threaded rod and the movable block when the servo motor is running. The horizontal movement of the movable sleeve can drive the feeding slide to move in the direction close to the cold pressing lower die. When the through hole at the end of the feeding slide is aligned with the material hole, the first telescopic rod is controlled to retract. When the first telescopic rod is retracted, the pushing plate can be driven to move in the direction away from the feeding slide. When the pushing plate moves to the outside of the storage bin, the PCB board radiator raw material can fall into the feeding slide. Then, when the first telescopic rod is extended, the pushing plate is squeezed to squeeze the PCB board radiator raw material toward the through hole at the end. The PCB board radiator raw material can fall into the material hole through the through hole, thereby realizing automatic loading of cold pressing processing and avoiding the slow speed and high risk of manual loading.

[0021] The utility model has the following advantages: when the second telescopic rod is extended, the pneumatic mechanical gripper can be driven by the connecting block to move in the direction close to the cold pressing lower die; when the pneumatic mechanical gripper moves to one side of the processed PCB board radiator, the pneumatic mechanical gripper can be used to clamp it; when the second telescopic rod is retracted, the pneumatic mechanical gripper is driven by the connecting block to move in the opposite direction; when the pneumatic mechanical gripper drives the PCB board radiator to the entrance of the material guide trough, the pneumatic mechanical gripper is released, and the PCB board radiator can fall into the material guide trough, thereby realizing automatic material collection after the PCB board radiator is processed, thereby reducing the workload of employees and improving intelligence and processing efficiency.

[0035] Working principle: When using the device of this technical solution, the servo motor 13 is first operated during loading. When the servo motor 13 is running, it drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 can drive the movable sleeve 7 to move horizontally through the movable block 12. The horizontal movement of the movable sleeve 7 can drive the loading slide 14 to move in the direction close to the cold pressing lower die 3.
