Fig. 9 The existing workpiece 100 is in the shape of a sheet structure. The stamping equipment is divided into a stamping station and a blanking station according to different usage states. The workpiece 10 is stamped at the stamping station, and the workpiece 100 is unloaded at the blanking station.

[0004] In the existing stamping process of the above-mentioned stamping equipment, the workpiece after stamping needs to be unloaded. During the unloading process of the workpiece, the stamping equipment needs to wait for the next stamping after unloading, so that the stamping equipment is continuously in a standby state. The waiting time is long, which affects the production efficiency and needs to be improved. Summary of the invention

[0005] In order to improve the problem that the long waiting time for unloading of stamping equipment affects the production efficiency, this technical solution provides a stamping die table structure.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A stamping die table structure comprises a machine base and an operating table arranged on the machine base, wherein the operating table is slidably connected to a workbench, and two stamping die seats are arranged on the workbench, and the two stamping die seats are distributed along the sliding direction of the workbench, and the stamping die seats are used for placing workpieces, and a stamping device is slidably connected to the machine base, and the sliding direction of the stamping device is perpendicular to the sliding direction of the workbench, and the stamping device moves toward the workbench to process the workpiece on the stamping die seat, and the operating table is provided with a driving structure, and the driving structure is used to drive the workbench to slide to realize the reciprocating movement of the stamping die seat.

[0008] Through the above technical solution, when the stamping die table structure is in normal use, the operating table is divided into two unloading stations and a stamping station located between the unloading stations on both sides according to different usage types. The driving structure of the operating table drives the workbench to slide. Based on the fact that two stamping die seats are installed on the workbench along its sliding direction, the workpiece is placed on the stamping die seat located below the stamping device, and the stamping device is driven to move toward the workbench to accurately stamp the workpiece on the stamping die seat. When the stamping is completed, the driving structure slides the stamping die seat to the unloading station for unloading to obtain the stamped workpiece. At this time, another stamping die seat moves to the stamping station to ensure that the stamping device can immediately process the workpiece on the next stamping die seat. The reciprocating movement of the workbench allows the two stamping die seats to be used alternately, ensuring that the stamping device is in working condition most of the time, improving equipment utilization, and thereby improving production efficiency.

[0009] Preferably, the stamping die seat is provided with a push rod hole, an ejector rod is slidably connected in the push rod hole, a clearance groove is opened along the inner peripheral wall of the push rod hole, the ejector rod has a limiting portion, the limiting portion is located in the clearance groove, and the ejector rod is provided with an elastic member, the elastic member is pressed tightly between the side wall of the clearance groove close to the push rod hole and the limiting portion;

[0010] The operating table is provided with a discharging device, which includes a material pushing driving member, a mounting seat and a material pushing rod arranged on the operating table, wherein the position of the material pushing rod corresponds to the ejector rod one by one, the mounting seat is slidably connected with respect to the operating table, and the material pushing driving member is used to drive the mounting seat to slide;

[0011] When the stamping die seat moves to above the discharge device, the push rod slides to drive the ejector rod to protrude from the ejector rod hole so that the workpiece is delivered.

[0012] Through the above technical scheme, when the position of the stamping die seat moves to above the discharge device, the stamping die seat is loaded with the stamped workpiece, and the push drive member drives the mounting seat to slide. Based on the fact that a push rod is fixed on the mounting seat, and the position of the push rod corresponds one to one with the position of the ejector rod, the push rod moves synchronously with the mounting seat to approach the stamping die seat, and is embedded in the ejector rod hole until it conflicts with the limiting part of the ejector rod, so that the push rod pushes the limiting part to overcome the elastic force of the elastic member in the yield groove. The elastic member is compressed to make the ejector rod slide along the ejector hole and then protrude from the upper end of the stamping die seat, thereby pushing the stamped workpiece to detach from the stamping die seat, thereby realizing automatic discharge of the workpiece, reducing the difficulty of removing the workpiece, and further improving production efficiency.

[0013] Preferably, the operating table comprises an upper platform and a lower platform, the upper platform slides relative to the lower platform in a vertical direction, and the lower platform is provided with a lifting device, and the lifting device is used to drive the upper platform to slide;

[0014] The lifting device includes a lifting column and a lifting drive, wherein the lifting column is slidably connected to the lower platform, the sliding direction of the lifting column is parallel to the sliding direction of the upper platform, and the lifting drive drives the lifting column to slide for lifting the upper platform;

[0015] The lower platform is provided with a support column, which protrudes from the side of the lower platform close to the upper platform. The position of the support column is opposite to the stamping device. When the stamping die seat moves to the bottom of the stamping device, the upper platform slides close to the lower platform so that the stamping die seat and the support column abut against each other.

[0016] Through the above technical scheme, a workpiece is placed on the stamping die base, which is now located below the stamping device. The lifting drive member drives the lifting column to slide, and the lifting column slides downward so that the upper platen synchronously slides close to the lower platen. Based on the alignment of the support column position of the lower platen with the stamping device, the upper platen drives the stamping die base to move against the upper end surface of the support column, so that when the stamping die base is subjected to pressure from the stamping device, the support column provides stable support for the stamping die base, thereby reducing damage or deformation of the upper platen caused by excessive pressure, thereby improving the stability and safety of the stamping operation.

[0017] Preferably, the upper platform is provided with a buffer, and two buffers are provided. The two buffers are located at opposite ends of the workbench along the sliding direction in a one-to-one correspondence, and the buffers are used for providing sliding buffer for the workbench.

[0018] Through the above technical solution, based on the reciprocating sliding mode of the workbench, two buffers are arranged at the two end points of the reciprocating movement of the workbench, which can effectively buffer the impact force between the workbench and the upper table plate during rapid sliding, making the sliding speed smoother, generating less noise or vibration, and improving stability.

[0019] Preferably, the upper platform is provided with a proximity switch 1 and a proximity switch 2, and the proximity switch 1 and the proximity switch 2 are arranged at two end positions of the upper platform along the sliding direction of the workbench;

[0020] When the proximity switch 1 is triggered, the driving structure stops running, and when the proximity switch 2 is triggered, the driving structure stops running.

[0021] Through the above technical solution, both proximity switch 1 and proximity switch 2 can be triggered by the workbench. When the workbench moves to the position of proximity switch 1 and is triggered, the drive structure stops running. When the drive structure starts again, it reverses and the workbench slides toward the direction of proximity switch 2. When proximity switch 2 is triggered, the drive structure stops running and changes direction again, thereby realizing automatic reciprocating movement of the workbench. The proximity switch is used in conjunction with precise detection to ensure that the workbench changes direction at a specific position, thereby improving work efficiency and reducing labor costs.

[0022] Preferably, the upper table plate is provided with a mounting frame, wherein two mounting frames are provided, and the proximity switch 1 and the proximity switch 2 are arranged on the two mounting frames one by one. The mounting frame is provided with an adjustment groove, and the length direction of the adjustment groove is parallel to the sliding direction of the workbench. The proximity switch 1 and the proximity switch 2 move along the adjustment groove to adjust the position.

[0023] Through the above technical solution, proximity switch 1 and proximity switch 2 are installed on the upper table plate through corresponding mounting frames, and proximity switch 1 and proximity switch 2 can both move along the length direction of the corresponding adjustment slot, so that proximity switch 1 and proximity switch 2 can be adjusted in position along the same moving direction as the workbench as needed to adapt to the sliding path range of the workbench, ensuring that the two proximity switches can accurately detect the position of the workbench, thereby triggering corresponding control actions and improving flexibility.

[0024] Preferably, the workbench is provided with a transmission assembly, and the transmission assembly is connected between the workbench and the driving structure for guiding sliding;

[0025] The transmission assembly includes a transmission seat, a connecting portion and a transmission sleeve, wherein the transmission sleeve is arranged on the driving structure, and the connecting portion is connected between the transmission seat and the transmission sleeve;

[0026] When the workbench slides, the transmission seat is used to approach the first proximity switch to trigger, and the transmission sleeve is used to approach the second proximity switch to trigger.

[0027] Through the above technical solution, the transmission assembly is responsible for transmitting the power of the driving structure to the workbench, so as to control the sliding direction and distance of the workbench. The transmission seat in the transmission assembly is connected to the workbench and cooperates with the driving structure. The transmission seat and the transmission sleeve cooperate to guide the sliding of the workbench to improve the guiding stability. When the workbench slides to the predetermined position, the transmission seat will approach and trigger proximity switch one. When the workbench slides to the predetermined position on the other side, the transmission sleeve will also approach and trigger proximity switch two.

[0028] Preferably, the upper platform is provided with a guide sleeve, the guide sleeve is fixed to the upper end surface of the upper platform, and the lower platform is provided with a guide shaft, the guide sleeve is sleeved on the guide shaft to guide the upper platform to slide.

[0029] Through the above technical solution, the through end of the guide sleeve slides freely along the guide shaft, the axis of the guide shaft is parallel to the sliding direction of the upper table plate, and the guide sleeve and the guide shaft cooperate to guide the sliding path of the upper table plate, thereby enhancing the sliding accuracy and improving the stability of the guided sliding.

[0030] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0031] 1. In this technical solution, the workpiece is placed on the stamping die seat located below the stamping device, and the stamping device is driven to move toward the workbench to accurately stamp the workpiece on the stamping die seat. The driving structure drives the workbench to slide, and the stamping die seat moves to the unloading station to obtain the finished workpiece. Another stamping die seat moves to the stamping station to put the workpiece in. The workbench reciprocates so that the two stamping die seats are used alternately, thereby improving production efficiency;

[0032] 2. This technical solution is achieved by slidingly connecting an ejector rod to the ejector hole of the stamping die seat. The operating table is provided with a discharge device. The position of the ejector rod in the discharge device corresponds to the ejector rod one-to-one. The push drive member drives the mounting seat to slide. The ejector rod overcomes the elastic force of the elastic member and pushes the ejector rod to slide along the ejector hole and then protrude. The ejector rod pushes the workpiece to detach from the stamping die seat, thereby reducing the difficulty of removing the workpiece and further improving production efficiency.
