[0002] A punch press is a stamping press. In national production, the stamping process has more and more uses because it saves materials and energy, is highly efficient, has low technical requirements for operators, and can produce products that cannot be achieved by mechanical processing through various mold applications.

[0003] Stamping production is mainly for sheet metal. Through the die, blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion can be done. In the punching machine, the workbench is used to place and fix the parts to be processed.

[0004] Traditional punching machine worktables usually achieve lifting and lowering motion through hydraulic systems or mechanical transmission systems. However, in actual use, the impact force generated by the punching machine on the worktable during processing can easily cause high wear or even breakage of the mechanical transmission system or hydraulic system, affecting the service life of the punching machine. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the impact force on the worktable during punching processing can easily cause high wear or even breakage of the mechanical transmission system or the hydraulic system, thus affecting the service life of the punching machine. The present application provides a punching machine with a liftable worktable.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A punching machine with a liftable workbench comprises an L-shaped base, a punching head is installed on the top of the L-shaped base, one end of the L-shaped base is symmetrically fixedly connected to a supporting slide rail, one end of the supporting slide rail is slidably connected to a supporting slide, a workbench body is installed between the two supporting slides, and a stamping die is installed on the top of the workbench body, a lifting slide rail is provided at one end of the L-shaped base, a lifting slider is slidably connected inside the lifting slide rail, one end of the lifting slider is fixedly connected to the workbench body, a lifting screw is rotatably connected inside the lifting slide rail, one end of the lifting screw is threadedly connected to the lifting slider, a lifting motor is fixedly connected to the top of the lifting slide rail, the output end of the lifting motor is fixedly connected to the lifting screw, one end of the lifting screw is provided with a transmission assembly that drives two supporting slides to move, and one end of the workbench body is provided with a blanking port adapted to the stamping die.

[0008] By adopting the above technical scheme, by setting the transmission component for coordinated use with the supporting slide rail and the supporting slide table, when the lifting motor is started to drive the workbench body to drive the stamping die and the workpiece to be stamped to move, the lifting screw cooperates with the transmission component to drive the two supporting slides to move closer to or away from each other along the length direction of the supporting slide rail. At the same time, the Shudie supporting slide is always in contact with the bottom of the workbench body, so that the supporting slide bears part of the impact force received by the workbench body, thereby effectively reducing the intensity of the impact force transmitted by the workbench body to the lifting slider and the lifting screw, reducing the wear between the lifting slider and the lifting screw, and extending the service life of the device.

[0009] Furthermore, the transmission assembly includes a transmission gear fixedly connected to the bottom of the lifting screw, one end of the two supporting slide rails is fixedly connected with a transmission rack, the transmission gear is installed between the two transmission racks, and the transmission rack is meshed with the transmission gear.

[0010] By adopting the above technical solution and setting the coordinated use of the transmission gear and the transmission rack, when the lifting motor is started to drive the lifting screw to rotate, the lifting screw drives the transmission gear to engage with the transmission rack, and the transmission rack drives the two supporting slides to move closer to or away from each other along the length direction of the supporting slide rail.

[0011] Furthermore, an altimeter is provided on one side of the lifting rail.

[0012] By adopting the above technical solution, a height gauge is provided to facilitate the judgment of the height at which the workpiece to be stamped is placed on the stamping die, thereby facilitating timely adjustment and improving the practicability of the device.

[0013] Furthermore, the top of the workbench body is symmetrically provided with guide slots, the bottom of the stamping die is symmetrically fixedly connected with guide sliders, and the guide sliders are slidably connected inside the guide slots.

[0014] By adopting the above technical solution and arranging the coordinated use of the guide slot and the guide slider, it is convenient to quickly complete the replacement of the stamping die, thereby improving the application range of the device.

[0015] Furthermore, a material discharge chute is opened at one end of the L-shaped base, and a T-shaped push plate is slidably connected inside the material discharge chute. An electric push rod is fixedly connected inside the L-shaped base, and an output end of the electric push rod is fixedly connected to the T-shaped push plate. One end of the L-shaped base is fixedly connected to a material box.

[0016] By adopting the above technical solution, by setting the electric push rod, T-shaped push plate and unloading port for coordinated use, when the stamping workpiece and debris pass through the stamping die and the unloading port and fall into one end of the L-shaped base, the electric push rod can be started to drive the T-shaped push plate to push the workpiece and debris into the interior of the material box for collection, thereby facilitating the automatic unloading of the stamping workpiece.

[0017] Furthermore, one end of the L-shaped base is fixedly connected to an arc-shaped filter screen, and the arc-shaped filter screen is installed above the material box.

[0018] By adopting the above technical solution and arranging the arc filter for use with the material box, it is convenient to classify and collect the debris and workpieces pushed into the material box, thereby improving the practicality of the device.

[0019] Furthermore, a baffle is symmetrically fixedly connected to one end of the L-shaped base, the two baffles are installed between the two supporting slide rails, and the T-shaped push plate is installed between the two baffles.

[0020] By adopting the above technical solution, by setting the baffle and the T-shaped push plate in coordination, it is convenient to guide and intercept the workpiece and debris that pass through the discharge port and fall into one end of the L-shaped base, thereby reducing the debris falling onto the surface of the supporting slide rail, thereby causing the supporting slide to slide and get stuck at one end of the supporting slide rail, thereby improving the practicality of the device.

[0021] Furthermore, a rubber pad is fixedly connected to the bottom of the L-shaped base.

[0022] By adopting the above technical solution, the impact force transmission between the L-shaped base and the ground is effectively weakened by arranging the rubber pad, thereby reducing noise transmission and improving the practicality of the device.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. By setting up the transmission component for coordinated use with the supporting slide rail and the supporting slide table, when the lifting motor is started to drive the workbench body to drive the stamping die and the workpiece to be stamped to move, the lifting screw cooperates with the transmission component to drive the two supporting slides to move closer to or away from each other along the length direction of the supporting slide rail. At the same time, the Shudie supporting slide is always in contact with the bottom of the workbench body, so that the supporting slide bears part of the impact force received by the workbench body, thereby effectively reducing the intensity of the impact force transmitted by the workbench body to the lifting slider and the lifting screw, reducing the wear between the lifting slider and the lifting screw, and extending the service life of the device.

[0025] 2. When the punching head is started to complete the punching of the workpiece placed on the top of the punching die, the finished product and the debris generated by the punching pass through the punching die and the discharge port and fall into the top of the L-shaped base and the inside of the discharge chute, and then the T-shaped push plate is pushed along the length direction of the discharge chute by starting the electric push rod, so that the T-shaped push plate pushes the workpiece and the debris to move to the inside of the material box. At the same time, the workpiece and the debris are guided and blocked by the two baffles when moving, which reduces the situation where the debris falls into one end of the support slide rail and causes the support slide to slide jam, and at the same time, the workpiece and the debris fall into the inside of the arc filter, and the debris passes through the arc filter and falls into the inside of the material box for collection, and at the same time, the workpiece falls into the inside of the arc filter, so as to facilitate the classification and collection of the stamped workpieces and debris, thereby improving the practicability of the device.
