Description

Technical Field

[0001] The invention relates to the technical field of stamping lathes, in particular to a continuous stamping lathe for mechanical processing. Background Art

[0002] The continuous stamping lathe is a kind of equipment used for mechanical processing, which can perform stamping operations continuously. This lathe usually has the characteristics of high-speed operation and high efficiency, and is suitable for mass production. However, in order to pursue the processing speed, the existing continuous stamping lathe does not have the limit capability, resulting in a low pass rate of workpieces, and the general limit device is difficult to achieve synchronous limit, which reduces the production efficiency.

[0003] The utility model patent with patent number CN202022528227.7 discloses a continuous stamping lathe for mechanical processing. The electric conveyor belt of the utility model runs intermittently at a uniform speed to transport the plates one by one to the position corresponding to the automatic feeding structure. The electric push rod retracts and runs, and drives the vacuum generator and the suction cup to move downward through the mounting plate. The suction cup contacts the upper surface of the plate, and the vacuum generator works. The air inlet valve in the vacuum generator opens and the air blow valve closes. The air in the suction cup is continuously sucked out through the hard tube, thereby forming a negative pressure in the suction cup, so that the suction cup automatically adsorbs the plate. After adsorption, the air inlet valve in the vacuum generator is closed, and the vacuum is maintained in the suction cup. The suction cup sucks the plate tightly, and the first motor runs, and the output shaft rotates, driving the bevel gear one to rotate. Since the lower end face of the bevel gear two is rotatably connected to the left side of the upper surface of the working plate through the plane bearing, the bevel gear two and the bevel The bevel gear one is meshed and connected, so that the bevel gear one can drive the bevel gear two to rotate, and then the vacuum generator and the suction cup are driven to rotate with the center of the bevel gear two as the center through the electric push rod one and the mounting plate. At the same time, the electric push rod one extends and operates, so that the suction cup absorbs the plate and rises, and the suction cup is adjusted to the position corresponding to the lower mold. The PLC controller controls the blowing valve in the vacuum generator to open, so that the vacuum is broken, and the plate adsorbed on the suction cup falls into the lower mold, so as to realize automatic loading of the plate. Although this patent solves the above problems, there are still problems that the workpiece cannot be effectively limited and the processing accuracy is low. Therefore, it is very necessary to design a continuous stamping lathe for mechanical processing that can synchronously and effectively limit the workpiece and can limit the workpiece in multiple directions to ensure that the workpiece does not deviate during the stamping process, improve the stamping accuracy, reduce the defective rate, and improve the processing efficiency. Summary of the invention

[0004] The object of the present invention is to provide a continuous stamping lathe for mechanical processing to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a continuous stamping lathe for mechanical processing, comprising a stamping machine, the stamping machine also comprising a limiting device, the limiting device comprising a pressing mechanism and a clamping mechanism, the pressing mechanism comprising a stamping block, a pressing plate, a spring column, and a limiting plate, the stamping block is slidably connected below the stamping machine, the pressing plate is arranged below the stamping block, the spring column is fixedly connected below the pressing plate, the limiting plate is fixedly connected below the pressing plate, the clamping mechanism comprises an operating table, an extrusion bevel block, a limiting bevel block, and a reset spring, the operating table is arranged below the limiting plate, the extrusion bevel block is fixedly connected below the pressing plate, the limiting bevel block is slidably connected above the operating table, the reset spring is fixedly connected to both sides of the limiting bevel block, the stamping block is fixedly connected to the punch surface in the stamping machine, and the spring column is The columnar sliding cavity on the operating table is slidably connected, the extruding inclined block is slidably connected to the upper surface of the limiting inclined block, and the reset spring is fixedly connected to the inner side of the operating table. The punching machine drives the punching block to press down, the punching block drives the pressure plate to press down, and the pressure plate drives the limiting plate to press down, and the limiting plate presses the workpiece for limiting. When the punching block rises, the spring column resets the pressure plate, and the pressure plate presses down while driving the extruding inclined block to press down. After the extruding inclined block is pressed down, its inclined surface touches the inclined surface of the limiting inclined block. The pressure of the extruding inclined block causes the limiting inclined block to move horizontally toward the inside of the operating table, thereby clamping and limiting the workpiece. When the extruding inclined block rises, the reset spring resets the limiting inclined block. The device can effectively limit the workpiece, and can cooperate with the pressure plate to press down to limit the workpiece in multiple directions, ensuring that the workpiece does not deviate during the stamping process, improving the stamping accuracy, reducing the defective rate, and improving the processing efficiency.

[0006] According to the above technical solution, a waste collecting device is arranged inside the operating table, and the waste collecting device comprises a material guiding structure and a material shaking structure, the material guiding structure comprises a spring plate, a material guiding plate, and a waste outlet, the spring plate is fixedly connected above the operating table, the material guiding plate is fixedly connected below the spring plate, and the waste outlet is opened at the bottom of the operating table, the material shaking structure comprises a downward pressing inclined plate, an offset inclined plate, a collecting bucket, a material throwing port, and a torsion spring, the downward pressing inclined plate is fixedly connected below the spring plate, the torsion spring is fixedly connected to the bottom of the operating table, the collecting bucket is fixedly connected above the torsion spring, the material throwing port is opened at the rear side of the collecting bucket, the offset inclined plate is fixedly connected to the front side of the collecting bucket, and the material guiding plate The upper surface of the operating table is penetrated, and the downward pressing inclined plate is slidably connected with the upper surface of the dislocated inclined plate. The limit plate will drive the spring plate to be pressed down, and the downward pressing of the spring plate will drive the guide plate to be pressed down. The guide plate is pressed down and inserted into the waste outlet, so that the waste generated by stamping can be quickly discharged. At the same time, the waste generated by stamping falls into the collecting bucket. At this time, the downward pressing of the spring plate drives the downward pressing inclined plate to be pressed down, and the inclined surface of the downward pressing inclined plate touches the inclined surface of the dislocated inclined plate, causing the dislocation of the dislocated inclined plate, so that the collecting bucket rotates and deviates. After the collecting bucket deviates, the torsion spring resets it. The torsion of the torsion spring is extremely large. The force generated by the reset causes the waste in the collecting bucket to be thrown out from the throwing port. Every time the waste falls, it will be thrown out immediately, effectively preventing the accumulation of waste and causing blockage.

[0007] According to the above technical solution, a discharging device is provided on the front side of the collecting barrel, and the discharging device includes a swinging material transport structure and an inertial material discharge structure. The swinging material transport structure includes a pull rod, a swing connecting rod group, and a discharge plate. The pull rod is hingedly connected to the front side of the punching block, and the swing connecting rod group is hingedly connected to the front side of the pull rod. The discharge plate is fixedly connected to the inner side of the swing connecting rod group. An inertial material discharge structure is provided below the discharge plate. The inertial material discharge structure includes a gravity push groove, a tension spring, a T-shaped slider, and a counterweight block. The gravity push groove is fixedly connected to the bottom of the discharge plate, and the tension spring is fixedly connected to the front and rear sides of the inner wall of the gravity push groove. The T-shaped slider is fixedly connected to the inner side of the tension spring, and the counterweight block is fixedly connected to the front side of the T-shaped slider. The T-shaped slider is slidably connected to the inside of the gravity push groove, and the T-shaped slider slides through the front side of the gravity push groove. The downward pressure of the pressure plate drives the pull rod and the pressure plate hinge to move in an arc shape, thereby pulling the swing connecting rod group to swing back and forth, and the swing connecting rod group drives the unloading plate to move obliquely back and forth to receive and feed materials reciprocatingly, so that the processed workpiece can be quickly delivered. In the process of the unloading plate moving forward, the counterweight block is thrown forward due to gravity, driving the T-shaped slider to slide with the front end of the gravity push groove. This process generates a forward force to quickly throw the workpiece out, and the unloading plate moves backward so that the tension spring pulls the T-shaped slider back, and the T-shaped slider drives the counterweight block to move backward, and the cycle is reciprocating. This device can quickly deliver the processed workpiece, and use gravity to deliver the workpiece more quickly, thereby preventing workpiece stacking and improving processing efficiency.

[0008] According to the above technical solution, a vibration reduction device is arranged below the gravity push groove, and the vibration reduction device includes a vibration reduction structure and a stress adjustment structure. The vibration reduction structure includes a base, a suspension, and a buffer spring. The base is fixedly connected below the operating table, and the suspension is hingedly connected to the top of the base, and the buffer spring is fixedly connected to the inner side of the suspension. A stress adjustment structure is arranged inside the base, and the stress adjustment structure includes a threaded rod, a turning handle, a sliding bottom plate, and a sliding groove. The threaded rod is fixedly connected to the inner side of the suspension, and the turning handle is threadedly connected to the surface of the threaded rod, and the sliding bottom plate is fixedly connected below the suspension. The sliding groove is slidably connected to the surface of the sliding bottom plate, and the sliding groove is fixedly connected to the bottom of the base, and the turning handle is fixedly connected to the bottom end of the buffer spring. The base can fix the punching machine, and the vibration generated by the punching machine is transmitted to the suspension. The shock is then eliminated through the buffer spring, and the aftershock is transmitted to the base through the suspension and disappears. When the stamping machine processes different workpieces, the power used is different, and the vibration generated is of different magnitudes. The vibration damping device needs to be adjusted to adapt to the vibration magnitude and increase the service life of the vibration damping device. By turning the handle, the vibration damping device moves on the threaded rod to squeeze or stretch the buffer spring, which plays a role in adjusting the stress of the buffer spring so that the buffer spring can adapt to vibrations of different magnitudes. The sliding base plate is translated in the slide groove to adjust the suspension angle. The more vertical the suspension is to the bottom surface, the tighter it is, and the greater the vibration damping force. The more parallel the suspension is to the bottom surface, the looser it is, and the smaller the vibration damping force. The device has a buffering effect on the stamping machine, and the adjustment of tightness prolongs the service life of the vibration damping device, and it will not be easily damaged due to frequent contact vibration, reducing the number of repairs and reducing the cost of use.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are: The present invention is provided with an extrusion bevel block, a limiting bevel block and a reset spring. The pressure of the extrusion bevel block causes the limiting bevel block to translate toward the inside of the operating table, thereby clamping and limiting the workpiece. When the extrusion bevel block rises, the reset spring resets the limiting bevel block. The device can effectively limit the workpiece and can cooperate with the downward pressing of the pressing plate to limit the workpiece in multiple directions, thereby ensuring that the workpiece does not deviate during the stamping process, improving the stamping accuracy, reducing the defective rate, and improving the processing efficiency. The present invention is provided with a downward pressing inclined plate, a dislocation inclined plate, a collecting bucket, a material throwing port, and a torsion spring. After the collecting bucket is offset, the torsion spring resets it. The torsion force of the torsion spring is extremely large. The force generated by the reset causes the waste in the collecting bucket to be thrown out from the material throwing port. Each time the waste falls, it will be thrown out immediately, effectively preventing the waste from accumulating and causing blockage. The present invention is provided with a gravity push groove, a tension spring, a T-shaped slider, and a counterweight block. The blanking plate moves backward so that the tension spring pulls the T-shaped slider back, and the T-shaped slider drives the counterweight block to move backward, and the cycle is repeated. The device can quickly send out the processed workpiece, and use gravity to send out the workpiece more quickly, thereby preventing the workpiece from stacking and improving the processing efficiency. The present invention is provided with a threaded rod, a rotating handle, a sliding bottom plate, and a sliding groove. The rotating handle is rotated to move the vibration reduction device on the threaded rod to squeeze or stretch the buffer spring, thereby adjusting the stress of the buffer spring so that the buffer spring can adapt to vibrations of different sizes. The device has a buffering effect on the punching machine, and the adjustment of tightness prolongs the service life of the vibration reduction device, and it will not be easily damaged due to frequent contact vibration, thereby reducing the number of maintenance times and reducing the cost of use.
