Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and more specifically, it relates to a high-speed precision punch press. Background Technology

[0002] A punch press, also known as a stamping press, is an important piece of equipment in traditional machining. It is characterized by energy and material saving, high work efficiency, and low operator requirements. It is widely used and mostly belongs to non-standard customized equipment. Its appearance and model vary depending on the application scenario. It is a major piece of equipment in industries such as automotive mold making. The principle of a punch press is to convert circular motion into linear motion. The main motor output drives the flywheel, which drives the gears, crankshaft connecting rods, etc. through the clutch to achieve the linear motion of the slide.

[0003] Punch press production processes are simple, repetitive, and fast. Many companies still operate them manually. According to human physiological principles, when people are in a noisy environment for a long time and perform such fast and repetitive actions, they are prone to physical fatigue and slowed reaction. Once their attention is lost, it can easily lead to tragedy. Nowadays, punch presses are equipped with safety mechanisms, but in the event of a punch press going out of control or the safety mechanism malfunctioning, the punch press will perform continuous punching and cutting actions. If the operator does not have time to react, they will be injured. However, adding extra support devices to demarcate a safe area for workers has the problem that the support range is not large enough and the support effect is not good enough.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-speed precision punch press, which aims to solve the problems of insufficient support range and inadequate protection effect of the safety support device in the punching area of ​​the punch press.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-speed precision punch press, comprising a punch press body, an upper punch die, and a lower punch die, wherein the upper punch die and the lower punch die are slidably connected to the punch press body, a control device is electrically connected to the punch press body, the control device is electrically connected to an electric cylinder, a telescopic rod is fixedly connected to the electric cylinder, a fixed seat is slidably connected to the telescopic rod, rotating components are rotatably connected to the two side walls of the fixed seat, and several supporting components are fixedly connected to the rotating components. The telescopic rod enters or leaves the punching area as the upper punch die and the lower punch die disperse or close, and the rotating components extend into or leave the punching area as the telescopic rod extends into or leaves the punching area in a dispersed or closed state.

[0007] The present invention is further configured such that: the cross-section of the rotating component is bent, and a plurality of the supporting components are respectively fixedly connected to the starting end, the ending end and the bend of the rotating component, and the rotating component is arranged opposite to each other on both sides of the fixed base.

[0008] The present invention is further configured such that: a fixing block is fixedly connected to each of the two side walls of the fixing base, and the rotating component is rotatably connected to the fixing block through a bushing.

[0009] The present invention is further configured such that: a fixing member is fixedly connected to the end of the telescopic rod away from the electric cylinder; the fixing member is rotatably connected to the rotating member through a connecting member; and the end of the connecting member away from the fixing member is rotatably connected to the bend of the rotating member.

[0010] The present invention is further configured such that: a through groove is provided on the rotating member, the end of the connecting member away from the fixing member extends into the through groove, and the supporting member passes through the rotating member and the connecting member and is rotatably connected to the connecting member.

[0011] The present invention is further configured such that the supporting member is an I-beam column.

[0012] In summary, this utility model has the following beneficial effects: The telescopic rod extends and retracts simultaneously, driving the opening and closing of the rotating component. The opening and closing of the rotating component expands or contracts the support range of the support component. When the punch press is working, the upper and lower dies open, allowing the operator to reach into the stamping area to retrieve an object. Simultaneously, the telescopic rod drives the support component into the stamping area, and the support component unfolds. The support component forms a support between the upper and lower dies, providing a certain protective space for the operator. In the event of a punch press malfunction or safety mechanism failure, when the punch press continuously performs downward cutting movements, the support component enhances its protective function, providing a larger support range, better effect, and improved machine tool operation safety. Furthermore, during normal operation, when the upper and lower dies close, the support range of the support component contracts and retreats from the stamping area under the action of the telescopic rod, thus not affecting the normal operation of the punch press.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A high-speed precision punching press, such as Figures 1-3 As shown, the press includes a press body 1, an upper die 2, and a lower die 3. The upper die 2 and the lower die 3 are slidably connected to the press body 1. The press body 1 is equipped with a control device 4, which is electrically connected to an electric cylinder 5. A telescopic rod 6 is fixedly connected to the lead screw of the electric cylinder 5. A fixed seat 7 is slidably connected to the telescopic rod 6. Rotating components 8 are rotatably connected to the two side walls of the fixed seat 7. Several supporting components 9 are fixedly connected to the rotating components 8. The telescopic rod 6 enters or leaves the stamping area as the upper die 2 and the lower die 3 open or close. The rotating components 8 are in a dispersed or closed state as the telescopic rod 6 enters or leaves the stamping area. The extension and retraction of the telescopic rod 6 drives the opening and closing of the rotating components 8, which in turn causes the supporting components 9 to expand or shrink their support range. When the press is working, the hot pressing of the upper die 2 and the lower die 3 is controlled by a program. The extension and retraction time of the electric cylinder 5 is also set by the program. By setting the time interval, when the upper die 2 and the lower die 3 of the punch press are opened, the operator reaches into the punching area to retrieve the object. The electric cylinder 5 drives the telescopic rod 6 into the punching area. At the same time, the sliding of the telescopic rod 6 drives the support 9 into the punching area and the support 9 unfolds. The support 9 forms a support between the upper die 2 and the lower die 3 of the punch press, providing a certain protective space for the operator. In the event of a punch press malfunction or safety mechanism failure, when the punch press continuously makes downward punching movements, the support 9 can enhance the protective effect, and the support range is larger, the effect is better, and the safety of the machine tool operation is improved. When the punch press is running normally, when the upper die 2 and the lower die 3 of the punch press are closed, the support range of the support 9 shrinks and is driven by the telescopic rod 6 to move backward out of the punching area, thus not affecting the normal operation of the punch press.

[0019] like Figures 2-3As shown, the electric cylinder 5 has significant advantages over other telescopic structures such as pneumatic cylinders and hydraulic cylinders in terms of speed control, end-point buffer control, intermediate positioning function, full closed-loop servo control, maintenance cost, energy saving and environmental protection, adaptability and system composition. The rotating part 8 has a broken-line cross-section, and several support parts 9 are fixedly connected to the starting end, bending point and end of the broken-line rotating part 8 respectively. The rotating parts 8 are respectively set opposite to each other on both sides of the fixed base 7. When the rotating parts 8 on both sides rotate, the support parts 9 located on the rotating parts 8 can expand the support range as the rotating parts 8 unfold. At the same time, the oppositely set rotating parts 8 can make the support of the unfolded support parts 9 more stable and the support range wider than a single set. The fixed base 7 has a through hole for the telescopic rod 6 to pass through, which facilitates the smooth sliding of the telescopic rod 6 on the fixed base 7. Fixed blocks 10 are fixed on each of the two side walls of the fixed base 7. The rotating part 8 is rotatably connected to the fixed block 10 through a bushing. The support parts 9 pass through the rotating part 8 and the fixed block 10 in sequence, and the support parts 9 act as the rotating shaft. When the rotating part 8 extends into the stamping area along with the telescopic rod 6, the support 9 located on the fixed block 10 only moves in the same direction as the telescopic rod 6. The support 9 located in other parts of the rotating part 8 can unfold along with the rotating part 8.

[0020] like Figures 1-2 As shown, a through groove 13 is provided between the upper and lower surfaces of the rotating component 8. The through groove 13 extends laterally through the rotating component 8. A connecting component 12 is rotatably connected to the bent position of the rotating component 8 inside the through groove 13. The through groove 13 facilitates the rotation of the connecting component 12. A support component 9 at the bent position passes through the rotating component 8 and the connecting component 12. A fixing component 11 is fixedly connected to the end of the telescopic rod 6 away from the motor. The end of the connecting component 12 away from the rotating component 8 is rotatably connected to the side wall of the fixing component 11. The fixing component 11 and the connecting component 12 are rotatably connected through a bushing. When the telescopic rod 6 extends or retracts, the fixing component 11 changes position with the extension or retraction of the telescopic rod 6. At this time, the included angle formed between the two connecting components 12 changes, and the length of the connecting component 12... If the angle remains constant, the change in the included angle of the connecting piece 12 causes the rotating piece 8 to switch between two states of expansion or contraction, thereby changing the support range of the support piece 9. The support piece 9 is set as an I-beam column. The steel material itself has good support properties. The I-beam column adopts an I-shaped cross-section design, which increases its load-bearing capacity and bending stiffness, giving it high tensile and compressive strength. Due to the rationality of its cross-sectional shape, the I-beam column can withstand large loads, including vertical loads and lateral forces, maintaining the stability and integrity of the structure and playing a good supporting role. When the upper die 2 and the lower die 3 of the punch press lose control and press down, the support piece 9, being set as an I-beam column, can provide better support.

[0021] Working Principle: The punch press is an automated punch press, controlled by a CNC device. Once the power is on and the die is installed and in the normally open state, the upper die 2 and lower die 3 are separated. The control device 4 is electrically connected to the PLC CNC screen. The power to the control device 4 is then turned on, a time interval is set on the CNC screen, and the start switch is pressed. This activates the electric cylinder 5, putting it into operation. The electric cylinder 5 drives the telescopic rod 6 into the punching area. After the telescopic rod 6 slides, it causes the rotating part 8 to unfold. After the rotating part 8 unfolds, the cross-sections of the two connecting parts 12 are almost a straight line, and several supporting parts 9 are dispersed and unfolded. Afterwards, the operator... When the button is pressed, the upper die 2 and lower die 3 of the punch press start working and move closer to close. Before closing, the electric cylinder 5 drives the telescopic rod 6 to retract and exit the punching area. The telescopic rod 6 slides towards the electric cylinder 5, causing the included angle formed by the two connecting parts 12 to decrease. The rotating part 8 closes, and several supporting parts 9 are in a closed and shrunken state. After the upper die 2 and lower die 3 complete the punching of the product, they will open, and the operator will start to remove the product. At this time, if the punch press goes out of control or the safety mechanism fails, the punch press will continue to punch downwards. The electric cylinder 5 will drive the telescopic rod 6 back into the punching area. The supporting parts 9 will play a supporting role, forming a certain safety area to protect the operator from injury.
