[0002] A push button switch is an electrical switch that controls the on / off state of an electrical device by mechanically pressing a button. It is easy to operate, fast, and simple in appearance. It is commonly found in various home appliances, car electronic products, computers, and other devices to facilitate user operation. This type of switch is usually used to control the on and off of lights, electrical appliances, and other equipment, as well as to select the operating mode of electrical equipment and realize device linkage.

[0003] Cold bending refers to the bending of metal at room temperature without heating. In electrical components, such as the shell processing of push button switches, the shell is placed in a tooling at room temperature and bent by the external force applied by the tooling to achieve the desired shape and angle. However, the shell is difficult to remove from the mold after cold bending, and it takes more time and manpower to complete this step, reducing production efficiency. In view of this, a cold bending tooling for push button switches is designed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cold bending tool for a push button switch, which solves the problem that the shell is difficult to remove from the mold after cold bending, and that more time and manpower are needed to complete this step, thereby reducing production efficiency.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a cold bending tool for a button switch, comprising a bottom plate and a top plate, the top of the bottom plate is fixedly connected to a lower die, the top of the lower die is connected to a jacking assembly, the outer surface of the jacking assembly is sleeved with a button switch housing, and the four corners of the top of the button switch housing are provided with bending parts;

[0006] An upper mold is fixedly connected to the middle of the top plate, and a molding cavity is provided at the bottom of the upper mold, and the molding cavity is located directly above the push button switch housing;

[0007] The lifting assembly comprises a lifting block, which is movably sleeved on the top of the upper die, a buffer spring is arranged inside the lifting block, and a positioning rod is fixedly connected to the inner top wall of the lifting block, and the positioning rod is slidably connected to the upper die.

[0008] Furthermore, the buffer spring is sleeved on the top of the outer surface of the positioning rod, the top of the buffer spring abuts against the inner top wall of the lifting block, and the bottom of the buffer spring abuts against the lower mold.

[0009] Furthermore, a locking bolt is movably inserted on the top plate, a locking screw hole is provided on the upper die, and one end of the locking bolt passes through the top plate and is threadedly connected to the inside of the locking screw hole.

[0010] Furthermore, a connecting head is fixedly connected to the top of the upper die, and the connecting head is fixedly connected to the stamping device.

[0011] Furthermore, the four corners of the top of the bottom plate are fixedly connected with limiting rods, the four corners of the top plate are provided with penetrating limiting holes, and the top of the limiting rod passes through the limiting hole and extends to the top of the top plate.

[0012] Furthermore, a fixing nut is provided on the top threaded sleeve of the outer surface of the limiting rod, and the outer diameter of the fixing nut is larger than the inner diameter of the limiting hole.

[0013] Furthermore, mounting bolts are movably inserted at the four corners of the top of the lower mold, and the bottoms of the mounting bolts pass through the lower mold and are threadedly connected to the bottom plate.

[0014] By means of the above technical solution, the utility model provides a cold bending tool for a push button switch, which has at least the following beneficial effects:

[0015] 1. When the push button switch housing needs to be cold-bent, the top plate drives the upper die to move downward, and the molding cavity at the bottom of the upper die corresponds to the bent portion at the top of the push button switch housing, and the bent portion begins to be cold-bent. At the same time, the lifting block in the lifting assembly moves downward under the pressure of the upper die, compressing the internal buffer spring. The compression of the buffer spring provides an upward reaction force for the lifting block, ensuring that the push button switch housing can be evenly stressed during the cold bending process to avoid local stress concentration; when the upper die completes the cold bending process and moves upward, the lifting block resets upward under the elastic force of the buffer spring, driving the push button switch housing back to its initial position, making it easy to remove the push button switch housing, thereby improving production efficiency and product quality.

[0016] 2. The positioning rod ensures the stable sliding of the lifting block on the upper die, and at the same time enables the buffer spring to maintain a stable motion trajectory during compression and recovery, thereby enhancing the overall stability of the tooling. The buffer spring provides an upward elastic force for the lifting block during the cold bending process. This force acts evenly on the push button switch housing through the lifting block, making the push button switch housing more evenly stressed during the cold bending process, effectively avoiding local deformation or damage caused by uneven force.

[0026] The lifting assembly 3 includes a lifting block 301, which is movably mounted on the top of the upper mold 6. A buffer spring 302 is provided inside the lifting block 301. A positioning rod 303 is fixedly connected to the inner top wall of the lifting block 301, and the positioning rod 303 is slidably connected to the upper mold 6.

[0027] The buffer spring 302 is sleeved on the top of the outer surface of the positioning rod 303, the top of the buffer spring 302 abuts against the inner top wall of the lifting block 301, and the bottom of the buffer spring 302 abuts against the lower mold 2. The positioning rod 303 ensures the stable sliding of the lifting block 301 on the upper mold 6, and at the same time allows the buffer spring 302 to maintain a stable motion trajectory during the compression and recovery process, thereby enhancing the overall stability of the tooling, and the buffer spring 302 provides an upward elastic force for the lifting block 301 during the cold bending process. This force acts evenly on the push button switch housing 4 through the lifting block 301, so that the push button switch housing 4 is subjected to more uniform force during the cold bending process, effectively avoiding local deformation or damage caused by uneven force.

[0028] A locking bolt 8 is movably inserted on the top plate 5, and a locking screw hole 9 is provided on the upper die 6. One end of the locking bolt 8 passes through the top plate 5 and is threadedly connected to the inside of the locking screw hole 9. Through the threaded connection between the locking bolt 8 and the locking screw hole 9, the upper die 6 can be firmly fixed on the top plate 5, ensuring that the upper die 6 will not move or misalign during the cold bending process, thereby ensuring the stability and accuracy of the processing.

[0029] The top of the upper die 6 is fixedly connected with a connector 10, which is fixedly connected to the punching device. The force generated by the punching device can be transmitted to the upper die 6 through the connector 10 to perform efficient cold bending processing.

[0030] The four corners of the top of the bottom plate 1 are fixedly connected with the limiting rod 11, and the four corners of the top plate 5 are provided with a through limiting hole 12.

The lower die 2 is fixed or loosened by rotating the mounting bolts 14, so that the mold replacement, cleaning and maintenance operations are convenient.

[0032] Working principle: When the push button switch housing 4 needs to be cold-bent, the top plate 5 drives the upper die 6 to move downward, and the molding cavity 7 at the bottom of the upper die 6 corresponds to the bending portion 401 at the top of the push button switch housing 4, and the bending portion 401 begins to be cold-bent. At the same time, the lifting block 301 in the lifting assembly 3 moves downward under the pressure of the upper die 6, compressing the internal buffer spring 302. The compression of the buffer spring 302 provides an upward reaction force for the lifting block 301, ensuring that the push button switch housing 4 can be evenly stressed during the cold bending process to avoid local stress concentration;

[0033] When the upper die 6 completes the cold bending process and moves upward, the lifting block 301 is reset upward under the elastic force of the buffer spring 302, driving the button switch housing 4 back to the initial position, so that the button switch housing 4 can be removed easily.
