Description

Technical Field

[0001] The present application belongs to the field of machinery and relates to a punching machine, and specifically to a punch rotating stripping and discharging mechanical high-speed punching machine. Background Art

[0002] High-speed punch presses are widely used in precision electronics, communications, household appliances, and automotive parts, particularly in the production of pneumatic rivets. The design principle of a high-speed punch press is to convert circular motion into linear motion. The main components of a high-speed punch press include a drive motor, clutch assembly, brake assembly, flywheel, and crankshaft. The drive motor drives the flywheel, which in turn, through the clutch assembly, drives the crankshaft. A connecting rod connected to the crankshaft drives the upper die holder of the die holder in linear motion to complete the punching operation.

[0003] Existing punch presses have two methods for removing material. For shaped parts with a larger fold than the base, one uses a punch and die. After the workpiece is removed from the punch, it is ejected from the end face. The ejection mechanism's stroke must be proportional to the length of the workpiece. This ejection time often exceeds half of the required cycle time, making it difficult to achieve with high-speed punch presses. Furthermore, the ejection direction and the forming force are at 90 degrees, necessitating an angle conversion mechanism within the punch press. Another method, for shaped parts with a smaller fold than the base, uses a punch and die. After the workpiece is removed from the punch, it is ejected from the front face. This ejection method requires the punch opening height to be greater than the fold height of the workpiece. While high-speed operation is possible, the punch press has a limited range of applications. Summary of the Invention

[0004] Based on the problems of the prior art, the present application provides a mechanical high-speed punching machine with a punch rotating to remove and discharge materials.

[0005] A punch rotary stripping and discharging mechanical high-speed punching machine is characterized in that it includes a machine base, a frame, a die assembly, a punch assembly and a stripping assembly. The frame is fixedly installed on the upper end of the machine base, and the die assembly is driven and guided on one lateral side of the lower part of the frame. The die assembly can move back and forth laterally in the frame, abutting against the punch assembly or away from the punch assembly; the punch assembly is limitedly installed on the other lateral side of the lower part of the frame, and the punch assembly is connected to a rotating drive mechanism.

[0006] By adopting the above technical solution, the die assembly and the punch assembly are arranged laterally relative to each other, the punch assembly is fixed, and the die assembly is laterally pressed relative to the punch assembly for processing. After the processing is completed, the die assembly is withdrawn and the workpiece remains on the punch assembly. Then, the punch assembly rotates downward, and while rotating, the material is removed along the stripping eccentric disk. The removed workpiece falls freely into the inclined discharge trough or conveyor belt to output the punch press, which changes the long-standing upper and lower die structure of the punch press. The material is automatically removed during the process of the punch rotating 90 degrees. The stripping speed is fast, and there is no need to increase the moving space of the punch press, thereby ensuring the processing speed.

[0007] Preferably, the die assembly includes a die base, a die tension spring, a die safety cylinder and a crankshaft connecting rod. The die base is installed in a limited sliding manner in the frame. The die is installed on one lateral side of the die base. The other side of the die base is connected to the die safety cylinder through multiple die tension springs. The die safety cylinder is hinged with one end of the crankshaft connecting rod, and the other end of the crankshaft connecting rod is hinged to the middle of the crankshaft. A flywheel pulley is installed at one end of the crankshaft.

[0008] By adopting the above technical solution, the flywheel pulley drives the crankshaft to rotate, thereby driving the die safety cylinder to move back and forth through the crankshaft connecting rod, and the die safety cylinder drives the die base to move in a guided manner. The expansion and contraction rhythm is controlled reliably, safely and stably. The die base and the die safety cylinder are connected by the die tension spring to play a buffering role, and the set pressure of the die safety cylinder plays an overload protection role.

[0009] Preferably, the punch assembly includes a punch bracket, a punch seat, a punch rotating disk and a punch rotating connecting rod. The punch bracket is fixed in the frame. The upper limit rotation of the punch bracket is equipped with a punch rotating disk. The radial side of the punch rotating disk is equipped with a punch seat, and the punch is installed in the punch seat. One side of the punch rotating disk is connected to the punch rotating connecting rod, and a punch tension spring is installed between the punch seat and the punch bracket.

[0010] By adopting the above technical solution, the punch rotating disk can rotate under the drive of the punch rotating connecting rod, and the punch rotating disk drives the punch seat to rotate back and forth between the horizontal stamping working position and the downward demolding position. The punch tension spring can assist the punch seat to reset to the accurate stamping working position.

[0011] Preferably, the punch rotating connecting rod includes a punch rotating cam, a first connecting rod and a second connecting rod. The punch rotating cam is coaxially mounted on the cutting eccentric shaft behind the frame. The punch rotating cam abuts the middle part of the first connecting rod. One end of the first connecting rod is hinged on the frame. The other end of the first connecting rod is hinged to one end of the second connecting rod. The other end of the second connecting rod is hinged to the radial side of the end face of the punch rotating disk.

[0012] By adopting the above technical solution, the punch rotating connecting rod is synchronously driven by the cutting eccentric shaft, and the cutting eccentric shaft is synchronously driven by the crankshaft, thereby ensuring that the action coordination time between the stamping action of the concave component and the rotating stripping action of the punch component is consistent; through the coordination of the connecting rod and the cam, the rotational motion of the cutting eccentric shaft is converted into a reciprocating swinging motion in a limited position, with a simple structure and high reliability.

[0013] Preferably, a demoulding assembly is installed on the punch assembly, and the demoulding assembly includes a demoulding eccentric disk, a demoulding device, a demoulding bearing and a demoulding tension spring. A demoulding eccentric disk is fixedly installed on the lower part of the punch bracket; the demoulding device guide sleeve is mounted on the punch seat, and a demoulding bearing is installed on the demoulding device. The outer circle of the demoulding bearing abuts the outer edge of the demoulding eccentric disk, and a demoulding tension spring is connected between the demoulding device and the punch rotating disk.

[0014] By adopting the above technical solution, the demolding assembly on the punch assembly assists in separating the workpiece from the punch assembly. The demolding assembly has a simple structure, the demolding device guide sleeve is mounted on the punch seat, and the demolding tension spring keeps the demolding device always in contact with the outer edge of the demolding eccentric disk. The demolding device rotates with the demolding device. At the same time, the demolding device moves in a straight line along the direction of the punch to separate the workpiece from the punch. The workpiece falls naturally under the action of gravity and is sent out of the punch press.

[0015] Preferably, a feeding mechanism and a cutting mechanism are installed on one side of the upper portion of the frame, the output end of the feeding mechanism is connected to the input end of the cutting mechanism, and the output end of the cutting mechanism is arranged above the die assembly.

[0016] By adopting the above technical solution, the punch press also includes a feeding mechanism and a cutting mechanism that cooperate with the stamping work, which automatically feeds the workpiece raw material into the punch press. The cutting mechanism cuts the workpiece raw material into workpiece blanks of the same length and can transport the workpiece blanks to the corresponding processing position of the die assembly.

[0017] Preferably, the feeding mechanism includes a feeder and a feeding drive mechanism, the feeding drive mechanism includes a feeding bracket, a feeding eccentric disk, a feeding rocker and a feeding push block, the feeding bracket is fixedly mounted on the frame, a feeding eccentric disk is installed in the middle of the feeding bracket for rotation driving, the radial side limit adjustment of the front end of the feeding eccentric disk is connected to the middle of the feeding rocker; the upper limit rotation of the feeding rocker is set on the frame, the lower end of the feeding rocker is hinged with a feeding push block, and the feeding push block guide limit is installed on the feeder.

[0018] By adopting the above technical solution, the specific structure of the feeding mechanism adopts the regular reciprocating swing of the feeding rocker to transport the workpiece raw material into the machine tool through the feeder. The action of the feeding rocker is driven by the feeding eccentric disk, and the feeding eccentric disk is synchronously driven by the cutting eccentric shaft.

[0019] Preferably, an eccentric adjustment block is provided on the feeding eccentric disc, and the feeding eccentric disc is connected to the feeding rocker via the eccentric adjustment block.

[0020] By adopting the above technical solution, the eccentric adjustment block can change the radial position of the connection point with the feeding rocker on the feeding eccentric disk, thereby changing the swing amplitude of the feeding rocker, and then adjusting the length of the workpiece fed in each swing.

[0021] Preferably, the cutting mechanism includes an upper cutter seat assembly and a lower cutter seat assembly. The upper cutter seat assembly and the lower cutter seat assembly are coaxially arranged relative to each other up and down. The lower cutter seat assembly is fixedly installed on the punch bracket of the punch assembly. The upper cutter seat assembly is connected to the cutting eccentric shaft, and the cutting eccentric shaft drives the upper cutter seat assembly to open and close up and down.

[0022] By adopting the above technical solution, the structure of the cutting mechanism is coordinated with the punch press, and the action of the cutter is also driven by the cutting eccentric shaft, so that the cutting action is coordinated with the feeding action. The actions of various parts of the punch press are uniformly driven, and the action coordination is high.

[0023] Preferably, the frame is fixedly mounted on the machine base at an angle, and the processing end surface of the die assembly forms an angle with the vertical direction; a workpiece blank limiting plate is provided at the lower part of the die assembly corresponding to the output end of the cutting mechanism.

[0024] By adopting the above technical solution, a workpiece blank limiting plate is set at the stopping position of the workpiece blank, and the end face of the die assembly receiving the workpiece blank is tilted at a certain angle, which effectively prevents the workpiece blank from sliding.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] The technical solution of this application changes the long-standing upper and lower die structures of punch presses, innovatively designing a method in which the die moves while the punch rotates. During the 90-degree rotation of the punch, the material is simultaneously removed via an eccentric disk. This eliminates the need for a material pusher mechanism and eliminates the time required for material pusher operation, achieving high speeds and adapting to workpieces of various sizes.

As the punch assembly 8 rotates, the demoulding assembly moves along the guide of the punch assembly 8 to push the workpiece out of the punch; a discharge chute 16 is fixedly installed on the frame 10 below the punch assembly 8. After the processed workpiece is separated from the punch, it falls into the discharge chute 16 and slides out of the equipment.

[0039] A feeding mechanism is installed on one side of the upper part of the frame 10, and the output end of the feeding mechanism is connected to the input end of the cutting mechanism 6.

The feeding mechanism feeds the workpiece raw material into the cutting mechanism 6, and the cutting mechanism 6 cuts the workpiece raw material into workpiece blanks 18 of the same length, and the workpiece blanks 18 are transported to the die assembly 4.

[0040] In order to prevent the workpiece blank 18 from being out of position, the frame 10 of this embodiment is tilted and fixed on the machine base 11, so that the die assembly 4 and the workpiece blank limiting plate 17 are both tilted, with an inclination angle of 5° to 15°, which can more stably support the workpiece blank 18 to prevent it from sliding or tipping over.

[0041] The specific structure of each part is as follows:
