Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rectifier bridge equipment, specifically relating to a patch-type rectifier bridge blanking mechanism. Background Technology
[0002] The structure of a surface-mount rectifier bridge typically consists of a package containing a chip and pins, with some pins extending from the side of the package and bent. During production, a large number of pins are formed by punching a frame. This frame, with its pins, participates in chip soldering and packaging. The packaged surface-mount rectifier bridge is then punched out of the frame using a punching die. During this process, the exposed pins are stamped and shaped, meaning the pin edges are cut from the frame and the pins are formed within the die. However, before punching, several surface-mount rectifier bridges are connected to a sheet-like frame for easy processing. After punching, the bridges become individual units scattered within the die, making them difficult to pick out quickly and easily. This affects the efficiency of separating the surface-mount rectifier bridge from the frame. Utility Model Content
[0003] This utility model provides a patch-type rectifier bridge blanking mechanism to solve the technical problem in the prior art that it is difficult to quickly and conveniently separate multiple patch-type rectifier bridges punched from the frame from the punching die.
[0004] This utility model includes: a blanking die, mounted on a press;
[0005] The push rod is located on one side of the worktable of the press and is adapted to the blanking die;
[0006] A blowing assembly is provided on the side of the punching die, and the air outlet of the blowing assembly corresponds to the punching die.
[0007] The blanking die includes an upper die and a lower die. The lower die is disposed on the worktable, and the upper die is disposed on the slide of the press. The lower die is adapted to the patch-type rectifier bridge frame, and the upper die is adapted to the lower die.
[0008] The lower mold has multiple material slots, which are adapted to the patch rectifier bridge, and both ends of the material slots are open.
[0009] In this invention, the blanking die blanks a frame with a patch-type rectifier bridge. The separated patch-type rectifier bridge will remain in the material groove of the lower die of the blanking die. The two ends of the material groove are open. The push rod can be inserted from one end of the material groove to push the internal patch-type rectifier bridge out completely from the other end of the material groove. Then, the remaining residue in the material groove is blown out by the blowing assembly so that the next blanking can be carried out.
[0010] Furthermore: the push rod includes a crossbar, and a plurality of push rods are provided on one side of the crossbar, the length, width and spacing of the push rods being adapted to the lower mold;
[0011] The two ends of the crossbar are slidably connected to the guide rod via sliding blocks;
[0012] The length of the guide rod is greater than or equal to the sum of the length of the lower die and the length of the ejector rod. The beneficial effect of this step is that the movement trajectory of the crossbar is limited by the slide and the guide rod, allowing the crossbar to drive several ejector rods to insert into the punching die and eject the patch-type rectifier bridge.
[0013] Furthermore: a spring is sleeved on the guide rod, and the spring is located on one side of the slide block and close to the lower mold. The beneficial effect of this step is that the spring can push the crossbar back to its original position.
[0014] Furthermore, a handle is provided on the other side of the crossbar. The beneficial effect of this step is that the handle makes it easier for the operator to push and pull the crossbar.
[0015] Furthermore: the blowing assembly includes a blowing block, which is fixed to the end of the cylinder piston rod. An air pipe is connected to the outside of the blowing block, and an air port is provided on the side of the blowing block facing the punching die. The beneficial effect of this step is that the blowing block is driven by the cylinder to perform linear reciprocating motion. During the movement, the blowing block blows air outward, which can cover the area of the lower die and blow away the residue in each material groove of the lower die.
[0016] The beneficial effects of this utility model are:
[0017] 1. This utility model uses a push rod to quickly and conveniently eject several patch rectifier bridges from the punching die, eliminating the need to pick out the patch rectifier bridges one by one, thus improving the unloading speed of the finished patch rectifier bridges.
[0018] 2. The blowing component can also blow away the residue in the mold after the punching is completed, so as to avoid the residue remaining in the mold and causing appearance damage to the patch rectifier bridge that is punched later. Attached Figure Description

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0027] Examples of embodiments of this utility model Figure 1 As shown, this utility model provides a patch-type rectifier bridge blanking mechanism.
[0028] This utility model includes: a blanking die 2, which is mounted on a press;
[0029] The push rod 3 is located on one side of the worktable 1 of the press and is adapted to the blanking die 2;
[0030] The blowing assembly 4 is located on the side of the punching die 2, and the air outlet of the blowing assembly 4 corresponds to the punching die 2.
[0031] The blanking die 2 includes an upper die 22 and a lower die 21. The lower die 21 is disposed on the worktable 1, and the upper die 22 is disposed on the slide of the press. The lower die 21 is adapted to the patch-type rectifier bridge frame, and the upper die 22 is adapted to the lower die 21.
[0032] The lower mold 21 has multiple material slots 211, which are adapted to the patch rectifier bridge, and both ends of the material slots 211 are open.
[0033] In the process of using this invention, the frame with the surface-mount rectifier bridge is first placed into the lower die 21. The upper die 22, under the action of a press, punches the frame with the surface-mount rectifier bridge. The separated surface-mount rectifier bridge remains in the material groove 211 of the lower die 21. Since both ends of the material groove 211 are open, the push rod 3 can be inserted from one end of the material groove 211 to push the surface-mount rectifier bridge out completely from the other end of the material groove 211. Then, the blowing assembly 4 is used to blow out the remaining residue in the material groove 211 for the next punching. The residue refers to the flash waste of the surface-mount rectifier bridge package and the waste generated during the lead punching process. If these residues are not cleaned out of the material groove 211 in time, they will damage the surface of the surface-mount rectifier bridge in the next punching process.
[0034] In one embodiment, the push rod 3 includes a crossbar 31, and a plurality of push rods 32 are provided on one side of the crossbar 31. The length, width and spacing of the push rods 32 are adapted to the lower mold 21, especially to the shape and position of the material groove 211.
[0035] The two ends of the crossbar 31 are slidably connected to the guide rod 33 through the slide block 311. The guide rod 33 restricts the movement path of the crossbar 31, ensuring that the top rod can be inserted into the material trough 211 in a straight line without interfering with the material trough 211.
[0036] The length of the guide rod 33 is greater than or equal to the sum of the length of the lower die 21 and the length of the ejector rod 32, ensuring that the ejector rod 32 will not contact the material groove 211 of the lower die 21 after retraction, and will not affect the normal punching process.
[0037] In one embodiment, a spring is fitted onto the guide rod 33. The spring is located on one side of the slide block 311 and close to the lower mold 21. Under the action of external force, the crossbar 31 overcomes the elastic force of the spring and extends the push rod 32 into the material groove 211. After the crossbar 31 loses external force, the spring can push the crossbar 31 back to its original position. The external force on the crossbar 31 can be provided by the operator or by power components such as cylinders or electric push rods. Of course, when the reset of the above-mentioned power components also requires power, the spring can be omitted.
[0038] In one embodiment, a handle 312 is provided on the other side of the crossbar 31. When the crossbar 31 is manually operated by an operator, the handle 312 can facilitate the operator to push and pull the crossbar 31.
[0039] In one embodiment, the blowing assembly 4 includes a blowing block 42, which is fixed to the end of the piston rod of the cylinder 41. The blowing block 42 typically has a vent hole, with an air pipe connected to the outside of the vent hole. The blowing block 42 has an air outlet (i.e., inside the vent hole) on the side facing the punching die. A solenoid valve or a manual valve can be connected to the air outlet. When the blowing block 42 moves, the solenoid valve or manual valve is opened, allowing air to blow outwards from the air outlet. The cylinder 41 drives the blowing block 42 in a linear reciprocating motion, covering the area of the lower die 21 and blowing away residue from each material slot 211 of the lower die 21. Furthermore, a pressure regulating valve, a silencer, or other components can be installed on the blowing outlet.
[0040] In the above embodiment, the push rod enables the patch rectifier bridges in multiple material slots 211 on the lower die 21 to be discharged from the lower die 21 simultaneously, eliminating the need to pick them out one by one and improving the discharge speed of the patch rectifier bridges.
