Description

Technical Field

[0001] This utility model relates to the field of punch press technology, specifically a punch press for producing metal brackets. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. A punch press is a type of stamping press, while a stamping die is a process equipment used in stamping to process materials into workpieces or semi-finished products; it is a major process equipment in industrial production. Using stamping dies to produce parts allows the use of mass-produced rolled steel plates or strips from metallurgical plants as blanks, and the process does not require heating, offering advantages such as high production efficiency, good quality, light weight, and low cost. To complete the stamping process, in addition to stamping the workpiece, the feeding and unloading of the workpiece are also crucial factors affecting stamping efficiency. Therefore, improving stamping dies and adding an unloading function is an effective means to improve stamping efficiency. However, existing punch presses for processing metal supports lack effective automatic unloading mechanisms, requiring manual unloading after processing, which is not only inefficient but also poses production safety hazards.

[0003] For example, patent application number 202321991565.1 discloses an automatic punching machine for metal bracket production. This utility model discloses an automatic punching machine for metal bracket production, which includes: a machine body, a stamping module, a detection module, and an unloading module. The stamping module, detection module, and unloading module are all located within the machine body. The stamping module includes a drive assembly, an upper die, and a lower die. This utility model's automatic punching machine for metal bracket production uses the detection module to detect the distance between the upper die and the lower die in real time. When the upper die rises to a preset position relative to the lower die, the unloading module pushes the workpiece away from the lower die, thereby achieving automatic unloading. However, this automatic punching machine for metal bracket production needs to operate below the die-casting device during material handling. If the die-casting device accidentally starts and falls during the material handling process, the pressing die-casting plate could injure workers, increasing safety hazards in production.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a punch press for the production of metal brackets. Utility Model Content

[0005] The purpose of this invention is to provide a punch press for producing metal brackets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punch press for producing metal brackets, comprising a placement platform, an upper mounting plate on the upper surface of the placement platform, a hydraulic pressing device on the upper surface of the mounting plate, a guide groove on the upper surface of the placement platform, a helical drive rod on the inner surface of the guide groove, a sliding placement plate on the surface of the helical drive rod, and a sliding connection between the sliding placement plate and the inner surface of the guide groove, a detachable mold on the upper surface of the sliding placement plate, and a material picking hole on the right side surface of the detachable mold.

[0007] Preferably, the upper right surface of the placement platform is provided with a mounting base, and the upper surface of the mounting base is provided with a material picking plate, and the material picking plate is set as an inclined surface.

[0008] Preferably, a light-receiving plate is provided behind the sliding placement plate, and a support frame is provided directly opposite the light-receiving plate.

[0009] Preferably, a servo motor is mounted on the upper surface of the support frame, and a threaded rod is mounted on the output end of the servo motor.

[0010] Preferably, a rotating disk is mounted on the lower outer surface of the threaded rod, and the rotating disk is fixedly mounted on the upper surface of the placement platform.

[0011] Preferably, a lifting block is spirally mounted on the outer surface of the threaded rod, and a binocular laser emitter is provided on the right side surface of the lifting block.

[0012] Preferably, the lifting block is provided with sliding plates at both ends, and the sliding plates are slidably connected to the inner surface of the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of a placement platform, mounting top plate, hydraulic pressing device, guide chute, screw drive rod, sliding placement plate, detachable mold, material picking hole, mounting base, and material picking plate, allows the sliding placement plate with the detachable mold to be pushed out from below the hydraulic pressing device for workpiece installation and removal via the screw drive rod. This facilitates worker operation and prevents the pressure plate of the hydraulic pressing device from falling and injuring workers during material handling, thus improving equipment safety. The material picking plate, when the metal support inside the detachable mold is die-cast and pushed out via the screw drive rod, inserts its inclined surface into the bottom of the detachable mold through the material picking hole, lifting the workpiece for easy removal.

[0015] 2. This utility model, through the arrangement of a light-receiving plate, a support frame, a servo motor, a threaded rod, a lifting block, a sliding plate, a binocular laser emitter, and a rotating disk, allows workers to measure the thickness of die-cast workpieces by displaying the laser emitted by the binocular laser emitter. This prevents the workpiece from being too thick and causing damage to the detachable mold and sliding placement plate during die-casting. The threaded rod allows the height of the binocular laser emitter to be adjusted according to the thickness of the metal support being processed, facilitating workpiece processing calibration.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3As shown, a punch press for producing metal brackets includes a mounting plate 101 on the upper surface of a placement platform 1, and a hydraulic pressing device 102 mounted on the upper surface of the mounting plate 101. A guide groove 2 is formed on the upper surface of the placement platform 1, and a screw drive rod 201 is mounted on the inner surface of the guide groove 2. The advantage of this arrangement is that, through the setting of the screw drive rod 201, the sliding placement plate 202 with a detachable mold 203 can be pushed out from below the hydraulic pressing device 102 for the installation and removal of workpieces. This facilitates the operation of workers and also avoids the pressure plate of the hydraulic pressing device 102 falling down and causing injury to workers when picking up and feeding materials, thereby improving the safety of equipment use.

[0023] Furthermore, a sliding placement plate 202 is helically mounted on the surface of the screw drive rod 201, and the sliding placement plate 202 is slidably connected to the inner surface of the guide groove 2. The advantage of this setting is that the sliding direction of the sliding placement plate 202 can be limited by the setting of the guide groove 2, so as to prevent it from deviating.

[0024] Furthermore, a detachable mold 203 is installed on the upper surface of the sliding placement plate 202, and a material picking hole 204 is provided on the right side surface of the detachable mold 203. The advantage of this setting is that, by setting the detachable mold 203, different detachable molds 203 can be replaced for use according to different metal brackets.

[0025] Furthermore, a mounting base 205 is provided on the upper right surface of the placement platform 1, and a material-retrieving plate 206 is provided on the upper surface of the mounting base 205. The material-retrieving plate 206 is set as an inclined surface. The advantage of this setting is that, by setting the material-retrieving plate 206, when the metal bracket inside the detachable mold 203 is completed and pushed out by the screw drive rod 201, the inclined material-retrieving plate 206 will be inserted into the bottom of the detachable mold 203 through the material-retrieving insertion hole 204 to lift the workpiece for easy material retrieval.

[0026] like Figure 4 As shown, a light-receiving plate 3 is provided behind the sliding placement plate 202, and a support frame 301 is provided directly opposite the light-receiving plate 3. A servo motor 302 is installed on the upper surface of the support frame 301, and a threaded rod 303 is installed at the output end of the servo motor 302. The advantage of this arrangement is that, by setting up the light-receiving plate 3, the laser emitted by the binocular laser emitter 306 can be displayed to help workers measure the thickness of the die-casting workpiece, thus avoiding the workpiece being too thick and causing damage to the detachable mold 203 and the sliding placement plate 202 during die casting.

[0027] Furthermore, a rotating disk 307 is installed on the outer surface of the lower end of the threaded rod 303, and the rotating disk 307 is fixedly arranged on the upper surface of the placement platform 1. The advantage of this setting is that, through the setting of the threaded rod 303, the height of the binocular laser emitter 306 can be adjusted according to the different thicknesses of the processed metal brackets, facilitating the calibration of workpiece processing.

[0028] Furthermore, a lifting block 304 is spirally installed on the outer surface of the threaded rod 303, and a binocular laser emitter 306 is arranged on the right side surface of the lifting block 304. The advantage of this setting is that, through the setting of the binocular laser emitter 306, the thickness of the unprocessed workpiece can be calibrated by emitting two laser beams.

[0029] Furthermore, sliding plates 305 are arranged at the front and rear ends of the lifting block 304, and a sliding connection is provided between the sliding plates 305 and the inner surface of the support frame 301. The advantage of this setting is that, through the setting of the sliding plates 305, the lifting block 304 can be slidably limited.

[0030] Working principle: When using the punching machine for producing metal brackets, first, start the spiral drive rod 201 to slide the sliding placement plate 202 with the detachable mold 203 through the spiral drive, push it out from below the hydraulic die pressing device 102, and then send the blank workpiece to be die-cast into the interior of the detachable mold 203. Then, according to the required thickness of the workpiece, start the servo motor 302 to drive the threaded rod 303 to rotate and adjust the height of the binocular laser emitter 306. After reaching the specified height, turn on the binocular laser emitter 306 to emit two lasers. The lower laser is blocked by the workpiece, and the upper laser is directly irradiated on the surface of the light receiving plate 3 without being blocked by the workpiece, indicating that the workpiece is qualified. After resetting the detachable mold 203 through the spiral drive of the spiral drive rod 201, use the hydraulic die pressing device 102 for die-casting processing. When the metal bracket inside the detachable mold 203 is die-cast and pushed out by the spiral drive rod 201, the material taking plate 206 with an inclined surface will insert into the bottom of the detachable mold 203 through the material taking jack 204 to lift the workpiece for convenient material taking. This is the working principle of the punching machine for producing metal brackets.
