Description

Technical Field

[0001] The utility model relates to a punching device, in particular to an automatic punching device for a watch movement die. Background Art

[0002] Mechanical watches are popular decorations and timekeeping tools. Their production and assembly processes are complex. When punching the movement, a specialized stamping mechanism is required to form it. This process is typically performed using a punching machine.

[0003] For example, the Chinese patent publication number CN219683694U discloses an automatic punching device for a watch movement die, which includes a processing table and a die table. The top of the processing table is fixedly connected to a mounting frame, the four corners of the bottom of the processing table are fixedly connected to support legs, a cylinder table is fixedly connected between the support legs, the top of the processing table is fixedly connected to the die table, the inside of the die table is fixedly connected to a die base, four groups of molds are provided in the die base, the molds are movably assembled in the die table, and a ejecting cylinder is fixedly connected to the top of the cylinder table. The automatic punching device for the watch movement die is provided with a mold, a die table, an ejecting rack, and an ejecting cylinder. The device adopts an assembled die table and die base, and a matching mold is embedded in the die base. After the stamping is completed, the ejecting cylinder is started, and the second piston rod pushes the ejecting rack upward to eject the movement quickly. The movement can be directly ejected without the need for staff to manually take it out, solving the problem of manual material removal.

[0004] Some problems were found during the use of the above-mentioned existing automatic punching device for watch movement dies. First, although the ejecting mechanism can effectively and quickly eject the movement, the ejected movement still needs to be manually picked up. Since the rapid impact will cause the metal movement to heat up, the movement that has just been ejected is still relatively hot, and the problem of easy burns when manually picking it up still exists. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic punching device for a watch movement die to solve the existing problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic punching device for a watch movement die, comprising a base, a bracket fixedly connected to the base, a connecting block symmetrically embedded and installed in the middle of the bracket, a limiting slide groove provided in the connecting block, a limiting slider slidably installed in the limiting slide groove, a processing table is provided above the base, connecting shafts are fixedly connected to both sides of the processing table, the connecting shafts are rotatably connected to the limiting slider, a lower mold is fixedly connected to the processing table, a hydraulic rod is fixedly connected to the base, and the lower end of the hydraulic rod is fixedly connected to the upper mold.

[0007] Preferably, a material discharge inclined plate is fixedly connected to the inner wall of the base, and a collection box is placed on the base.

[0008] Preferably, an electromagnetic latch is fixedly connected to the bottom of the processing table, and a limiting hole is provided in the connecting block, and the limiting hole cooperates with the electromagnetic latch.

[0009] Preferably, an interference block is fixedly connected to the side surface of the connecting block on one side, and a rotating block is fixedly connected to a position near the edge of one end of the connecting shaft, and the rotating block and the interference block cooperate with each other.

[0010] Preferably, the side surface of the limiting sliding block on the other side is fixedly connected to the adjusting motor through a motor frame, and the output end of the adjusting motor is fixedly connected to the connecting shaft.

[0011] Preferably, a return spring is fixedly connected to the rear of the limiting sliding block, and the other end of the return spring is fixedly connected to the inner wall of the limiting sliding groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By starting the regulating motor to drive the lower mold to rotate 180 degrees, the lower mold is turned upside down, and then the stamped movement is dumped out. The movement will fall onto the unloading inclined plate, and then slide down the unloading inclined plate to the collection box for storage. Compared with the existing device, there is no need for manual intervention in the discharge of materials, which can minimize the problem of workers being burned by the movement.

[0014] 2. Through the cooperation between the rotating block and the interference block, the mold is turned 180 degrees under the drive of the processing table, so that the connecting block can move forward and then quickly reset under the push of the return spring, thereby generating a certain vibration to assist in the discharge of the movement in the lower mold, avoiding the problem of the movement being stuck inside the lower mold and unable to fall naturally.

[0015] 3. Starting the electromagnetic latch can extend the latch and insert it into the limit hole, thereby fixing the position of the lower mold and avoiding the problem of the lower mold rotating and moving during stamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: an automatic punching device for a watch movement die, comprising a base 1, a bracket 101 fixedly connected to the base 1, a connecting block 2 symmetrically embedded and installed at the middle of the bracket 101, a limiting slide groove 201 is provided in the connecting block 2, a limiting slider 304 is slidably installed in the limiting slide groove 201, a processing table 3 is provided above the base 1, connecting shafts 301 are fixedly connected on both sides of the processing table 3, the connecting shafts 301 are rotatably connected to the limiting slider 304, a lower mold 4 is fixedly connected to the processing table 3, a hydraulic rod 501 is fixedly connected to the base 1, and an upper mold 5 is fixedly connected to the lower end of the hydraulic rod 501.

[0023] In this embodiment, the upper mold 5 can be driven downward by starting the hydraulic rod 501, and the upper mold 5 cooperates with the lower mold 4 to perform stamping to manufacture the movement. After the stamping is completed, the hydraulic rod 501 is used to drive the upper mold 5 to reset. At this time, since the connecting shaft 301 is rotatably connected to the limit slider 304, the processing table 3 can drive the lower mold 4 to flip one hundred and eighty degrees, so that the lower mold 4 is turned upside down, and the stamped movement is dumped out to complete the unloading operation of the movement. Then, the processing table 3 is turned over again to drive the lower mold 4 to reset, and the stamping operation can be performed again. No manual intervention is required. While increasing the unloading speed, it can effectively prevent the operator from being burned when removing the movement.

[0024] Among them, in order to achieve the purpose of fixing the lower mold 4, this device adopts the following technical solutions: a blanking inclined plate 102 is fixedly connected to the inner wall of the base 1, a collection box 103 is placed on the base 1, an electromagnetic plug 303 is fixedly connected to the bottom of the processing table 3, and a limiting hole 202 is opened in the connecting block 2, and the limiting hole 202 cooperates with the electromagnetic plug 303.

[0025] The falling movement is received by the unloading inclined plate 102, and the movement will slide down into the collection box 103 for collection, to prevent the movement from falling directly into the collection box 103 and being damaged due to the high falling height. The electromagnetic latch 303 can be activated to extend the latch and insert it into the limiting hole 202, thereby fixing the position of the lower mold 4 to prevent the lower mold 4 from rotating and moving during the stamping process.

[0026] Among them, in order to achieve the purpose of vibration-assisted blanking, this device adopts the following technical solutions: an interference block 203 is fixedly connected to the side of the connecting block 2 on one side, and a rotating block 302 is fixedly connected to the edge of one end of the connecting shaft 301. The rotating block 302 cooperates with the interference block 203. The side of the limiting slider 304 on the other side is fixedly connected to the adjusting motor 306 through the motor frame. The output end of the adjusting motor 306 is fixedly connected to the connecting shaft 301. A return spring 305 is fixedly connected to the back of the limiting slider 304, and the other end of the return spring 305 is fixedly connected to the inner wall of the limiting slide 201.

[0027] By starting the adjustment motor 306, the connecting shaft 301 can be driven to rotate. The rotation of the connecting shaft 301 can drive the lower mold 4 and the rotary block 302 to rotate. The rotary block 302 cooperates with the interference block 203, and then when the electromagnetic latch 303 rotates and contacts the interference block 203, it will push the connecting block 2 forward a certain distance. After the connecting shaft 301 drives the processing table 3 to rotate one hundred and eighty degrees, the connection and contact between the electromagnetic latch 303 and the interference block 203 will disappear. Under the push of the return spring 305, the limit slider 304 will quickly reset, thereby generating a certain vibration to assist the movement in the lower mold 4 to fall out.

[0028] The working principle and use process of the present invention: when using, the device needs to be placed in a suitable position, and starting the hydraulic rod 501 can drive the upper mold 5 to move downward, and the upper mold 5 cooperates with the lower mold 4 to perform stamping and manufacturing of the movement. After the stamping is completed, start the adjustment motor 306 to drive the processing table 3 to rotate, and the rotation of the processing table 3 will drive the lower mold 4 to flip over. After the lower mold 4 flips one hundred and eighty degrees, the lower mold 4 is turned upside down, and at the same time, the connecting block 2 will move forward and then quickly reset, driving the lower mold 4 to generate a certain vibration. At this time, the movement punched inside the lower mold 4 will fall onto the blanking inclined plate 102, and then slide up and down the blanking inclined plate 102 to the inside of the collection box 103 for storage.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
