Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and more specifically, to a pneumatic emergency braking device for a stamping equipment. Background Art

[0002] In industrial production, as an important processing machine, stamping equipment is widely used in many fields such as automobile manufacturing, electronic equipment production, and hardware processing. Its efficient and precise stamping operation can quickly process raw materials into various parts with complex shapes, greatly improving production efficiency. However, during the operation of stamping equipment, due to the involvement of high-speed rotating mechanical components and powerful stamping power, once an abnormal situation occurs, such as equipment failure or operator's misoperation, if timely and effective braking cannot be achieved, serious safety accidents will be caused, which may not only lead to equipment damage but also pose a great threat to the personal safety of operators.

[0003] In the automotive manufacturing industry, stamping equipment is used to produce a large number of body parts, such as car doors and hoods. The stamping process of these parts is usually carried out at high speed and high pressure. Once the equipment suddenly fails and lacks reliable emergency braking means, the high-speed rotating stamping die may cause limb crushing injuries to workers who are debugging the equipment or replacing the die. Moreover, the abnormal operation of stamping equipment may also lead to a large number of semi-finished products being scrapped, resulting in high economic losses. In the field of electronic equipment production, precision stamping equipment is responsible for producing tiny but crucial electronic components. Due to the extremely high precision requirements of the production environment, if the equipment gets out of control during production due to the lack of emergency braking, it will not only damage expensive dies but also may lead to the unqualified quality of the entire batch of products, seriously affecting the production progress and market reputation of the enterprise.

[0004] From the perspective of industry norms, authoritative organizations such as the Occupational Safety and Health Administration (OSHA) have long clearly stipulated that stamping equipment must be equipped with an effective emergency braking system to ensure that the equipment can be quickly stopped in case of emergencies and to protect the safety of personnel. However, the actual situation is that most of the braking systems equipped on current stamping equipment often seem inadequate when facing extreme situations such as the failure of the pneumatic channel. When the pneumatic system leaks, the air pressure is insufficient or other failures occur, the braking device relying on pneumatic drive often cannot work properly, thus making the stamping equipment out of control and increasing potential safety hazards; in view of this, we propose a pneumatic emergency braking device for a stamping equipment. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The safety of the stamping equipment is greatly improved by the present invention. Under normal working conditions, smooth deceleration braking can be achieved through the pneumatic deceleration mechanism, avoiding damage to the equipment itself and operators caused by the impact force generated by the sudden stop of the equipment. In the event of a malfunction of the pneumatic component or the air supply mechanism, the emergency braking mechanism can respond quickly and stop the equipment within a short time, preventing safety accidents caused by the continuous operation of the equipment, and ensuring the personal safety of the operators and the normal use of the equipment.

[0022] 2. The present invention adopts a dual braking method combining pneumatic deceleration and emergency braking, enhancing the reliability of the braking device. A single pneumatic braking method may fail in case of a pneumatic failure. However, when the pneumatic system is normal, the device can perform effective deceleration braking through the pneumatic deceleration mechanism; when the pneumatic system has problems, the emergency braking mechanism can immediately come into play to ensure that the equipment can be braked under any circumstances, reducing the risk of equipment damage and production interruption caused by braking failure, and improving the reliability and stability of the operation of the stamping equipment.

[0023] 3. In the emergency situation where the pneumatic system fails, the emergency braking mechanism can respond quickly. After the striker hits the trigger rod, the movable sleeve moves quickly to disconnect the output end of the driving mechanism from the deceleration rod, enabling the stamping module to stop moving in an extremely short time, effectively avoiding serious safety accidents caused by equipment out of control, and ensuring the personal safety of the operators and the integrity of the equipment.

[0024] 4. By making the output end of the driving mechanism idle in an emergency, the present invention avoids damage to the equipment caused by the huge impact force generated by forced braking. Traditional emergency braking methods may cause damage to the transmission components, connection components, etc. of the equipment due to excessive instantaneous braking force. However, this disconnection-type emergency braking method can effectively reduce this risk and extend the service life of the equipment.

[0025] 5. The present invention combines two modes: normal deceleration braking and emergency braking. The emergency braking method is unique and effective, making the entire braking system more reliable. Under normal circumstances, smooth deceleration is achieved through pneumatic and friction braking; in case of emergency, rapid braking is achieved through a mechanically triggered disconnection method. The two modes complement each other to ensure effective braking control of the stamping equipment under various conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] As Figures 1 to 11 shown, a pneumatic emergency braking device for a stamping device according to the present invention includes a base 1, a bracket 2 is provided on the base 1, a stamping table 3 is provided at the bottom end of the bracket 2, a driving mechanism 4 is provided at the top end of the bracket 2, a stamping module 5 is slidably provided on the bracket 2, the top end of the stamping module 5 is connected to the output end of the driving mechanism 4, a housing 6 is provided at the top end of the bracket 2 above the stamping module 5, a pneumatic deceleration mechanism 7 is provided on the housing 6, one end of the pneumatic deceleration mechanism 7 is provided with an emergency braking mechanism 8, one end of the emergency braking mechanism 8 is connected to the pneumatic deceleration mechanism 7, and the other end of the emergency braking mechanism 8 is connected to the output end of the driving mechanism 4;

[0048] The pneumatic deceleration mechanism 7 includes a pneumatic component 701, a deceleration component 702 and a trigger component 703. The pneumatic component 701 is provided inside the housing 6, the deceleration component 702 is provided on the outer wall of the housing 6, the deceleration component 702 is sleeved on one end of the emergency braking mechanism 8, and the trigger component 703 is provided inside the pneumatic component 701;

[0049] The trigger component 703 includes a compression spring 7031, an elliptical block 7032 and a firing pin 7033. The compression spring 7031 is provided inside the pneumatic component 701 near one end of the deceleration component 702, the elliptical block 7032 is slidably provided inside the pneumatic component 701, and the firing pin 7033 is fixedly provided at one end of the elliptical block 7032 away from the compression spring 7031;

[0050] Gas is input into the pneumatic component 701 through the air supply mechanism. The gas squeezes the elliptical block 7032 to compress the compression spring 7031, and the compression spring 7031 squeezes the deceleration component 702 to decelerate and brake the emergency braking mechanism 8; when the pneumatic component 701 or the air supply mechanism fails, the gas inside the pneumatic component 701 disappears, and the compression spring 7031 releases kinetic energy to push the elliptical block 7032 and the ejector pin 7033 out of the pneumatic component 701, and the ejector pin 7033 hits the emergency braking mechanism 8 at the other end to achieve emergency braking.

[0051] When the stamping equipment is running normally and braking operation is required, the air supply mechanism starts to work and inputs gas into the pneumatic component 701. The gas entering the pneumatic component 701 generates pressure, which acts on the elliptical block 7032 and pushes the elliptical block 7032 to slide in the pneumatic component 701 towards the direction close to the compression spring 7031. As the elliptical block 7032 slides, it squeezes the compression spring 7031, causing the compression spring 7031 to undergo elastic deformation and store elastic potential energy. Since the compression spring 7031 is arranged close to the deceleration component 702, the squeezed compression spring 7031 exerts a force on the deceleration component 702. The deceleration component 702 is sleeved on one end of the emergency braking mechanism 8. Under the action of the compression spring 7031, the deceleration component 702 hinders the emergency braking mechanism 8, thereby affecting the output end of the drive mechanism 4 connected to the emergency braking mechanism 8, making the movement speed of the output end of the drive mechanism 4 gradually decrease, and finally achieving the deceleration braking of the stamping module 5 to make the stamping equipment stop smoothly.

[0052] When the pneumatic component 701 or the air supply mechanism fails due to a fault, the gas inside the pneumatic component 701 disappears, and the gas pressure acting on the elliptical block 7032 also disappears. At this time, the compression spring 7031 that was previously squeezed and stored elastic potential energy starts to release kinetic energy and returns to its original state. During this process, the compression spring 7031 pushes the elliptical block 7032 and the ejector pin 7033 fixed on the elliptical block 7032 to quickly rush out of the pneumatic component 701. The ejected ejector pin 7033 hits one end of the emergency braking mechanism 8, and the other end of the emergency braking mechanism 8 is connected to the output end of the drive mechanism 4. The impact of the ejector pin 7033 triggers the braking action of the emergency braking mechanism 8, enabling it to quickly brake the output end of the drive mechanism 4, so that the stamping module 5 quickly stops moving and avoids danger caused by the equipment getting out of control.

[0053] The present invention adopts a dual braking method combining pneumatic deceleration and emergency braking, enhancing the reliability of the braking device. A single pneumatic braking method may fail in case of pneumatic failures. When the pneumatic system is normal, the device can perform effective deceleration braking through the pneumatic deceleration mechanism 7; when problems occur in the pneumatic system, the emergency braking mechanism 8 can immediately come into play to ensure that the equipment can achieve braking under any circumstances, reducing the risk of equipment damage and production interruption caused by braking failure, and improving the reliability and stability of the stamping equipment operation.

[0054] In an embodiment of the present invention, the pneumatic component 701 includes an air duct 7011, an air inlet hole 7012, a baffle 7013, and fine holes 7014. The air duct 7011 is arranged inside the housing 6. The air inlet hole 7012 is opened at one end of the top of the air duct 7011. The air inlet hole 7012 is connected to an external air supply mechanism. The baffle 7013 is fixedly arranged at one end of the air duct 7011 away from the deceleration component 702. The fine holes 7014 are opened on the baffle 7013. One end of the emergency braking mechanism 8 is inserted into the fine holes 7014. In the present invention, gas enters the air duct 7011 through the air inlet hole 7012. The air duct 7011 serves as a gas flow passage and accommodates the entering gas. The gas entering the air duct 7011 generates pressure, and this pressure acts on the ellipsoidal block 7032, pushing the ellipsoidal block 7032 to slide in the air duct 7011 in the direction close to the compression spring 7031. As the ellipsoidal block 7032 slides, it will squeeze the compression spring 7031, causing the compression spring 7031 to undergo elastic deformation and store elastic potential energy.

[0055] In an embodiment of the present invention, the air duct 7011 is in an L shape. The compression spring 7031 is arranged inside the air duct 7011 at one end close to the deceleration component 702. The ellipsoidal block 7032 is slidably arranged inside the air duct 7011. One end of the deceleration component 702 is movably inserted into the bottom end of the air duct 7011.

[0056] As another embodiment of the present invention, the deceleration component 702 includes a housing 7021, a hinge rod 7022, a friction arc block 7023, a rotating column 7024, a tension spring A 7025, and an extrusion block 7026. The housing 7021 is arranged on the outer wall of the housing 6. The hinge rods 7022 are symmetrically connected inside the housing 7021. The friction arc block 7023 is hingedly connected to the hinge rods 7022. The rotating column 7024 is rotatably arranged at one end of the friction arc block 7023 away from the hinge rods 7022. One end of the tension spring A 7025 is connected to the inner wall of the friction arc block 7023, and the other end of the tension spring A 7025 is connected to the hinge rods 7022. The bottom end of the extrusion block 7026 passes through the housing 7021 and is movably inserted between the two rotating columns 7024. The top end of the extrusion block 7026 is movably inserted into the air duct 7011.

[0057] As another embodiment of the present invention, the position where the extrusion block 7026 is inserted between the two rotating columns 7024 is in an inverted cone shape. One end of the extrusion block 7026 away from the rotating column 7024 is connected to the bottom end of the air duct 7011 through a tension spring B 7027. A slope 7028 is provided on the part of the extrusion block 7026 inserted into the air duct 7011, and one end of the compression spring 7031 away from the ellipsoid block 7032 contacts the slope 7028.

[0058] When the stamping equipment needs to be braked normally, the external air supply mechanism starts to work, and conveys gas into the air duct 7011 through the air inlet hole 7012. The gas entering the air duct 7011 generates pressure, pushing the ellipsoid block 7032 to move in the direction of the compression spring 7031, and then squeezing the compression spring 7031.

[0059] After the compression spring 7031 is squeezed, its elastic force acts on the slope 7028 of the extrusion block 7026. Due to the existence of the slope 7028, the force of the compression spring 7031 is decomposed into a vertically downward component force, pushing the extrusion block 7026 to move downward. At the same time, the tension spring B 7027 is stretched.

[0060] The bottom end of the extrusion block 7026 is in an inverted cone shape. As it is inserted downward between the two rotating columns 7024, the inverted cone-shaped extrusion block 7026 will force the two rotating columns 7024 to expand outward. The rotation of the rotating column 7024 will drive the friction arc block 7023 connected thereto to rotate around the hinge rod 7022, causing the friction arc block 7023 to expand outward, and the tension spring A 7025 is stretched.

[0061] The expanded friction arc block 7023 is in close contact with the components of the internal emergency braking mechanism 8, generating frictional force. This frictional force acts on the emergency braking mechanism 8, and then affects the output end of the driving mechanism 4 connected to the emergency braking mechanism 8, gradually reducing the movement speed of the output end of the driving mechanism 4, and realizing the deceleration braking of the stamping module 5.

[0062] As another embodiment of the present invention, the emergency braking mechanism 8 includes a trigger rod 801, a fixed rod 802, an inclined rod 803, a collar 804, a movable sleeve 805 and a deceleration rod 806. The fixed rod 802 is arranged on the housing 6, the inclined rod 803 is hinged to the fixed rod 802, one end of the trigger rod 801 is fixedly connected to the top end of the inclined rod 803, the other end of the trigger rod 801 is inserted into the fine hole 7014, the top end of the collar 804 is fixedly connected to the inclined rod 803, the movable sleeve 805 is rotatably inserted into the collar 804, one end of the deceleration rod 806 is inserted into the movable sleeve 805, the other end of the deceleration rod 806 is inserted into the outer shell 7021, and the output end of the driving mechanism 4 is inserted into the end of the movable sleeve 805 away from the deceleration rod 806.

[0063] As another embodiment of the present invention, a right-angled hole 8051 is provided at one end of the movable sleeve 805 close to the deceleration rod 806, and a clamping groove 8052 is provided at one end of the movable sleeve 805 close to the driving mechanism 4;

[0064] A clamping rod A8061 is provided on the outer wall of the deceleration rod 806, and a clamping rod B407 is provided at the output end of the driving mechanism 4. The clamping rod A8061 is movably inserted into the right-angled hole 8051, and the clamping rod B407 is movably inserted into the clamping groove 8052.

[0065] As another embodiment of the present invention, a friction disc 8062 is provided at one end of the deceleration rod 806 away from the clamping rod A8061. The friction disc 8062 is rotatably inserted into the outer shell 7021. The friction arc block 7023 expands outward and presses against the inner wall of the friction disc 8062 to generate frictional force, causing the deceleration rod 806, the movable sleeve 805, and the output end of the driving mechanism 4 to decelerate.

[0066] When the stamping equipment needs to be normally braked, the air supply mechanism conveys gas to the air passage 7011 of the pneumatic component 701. The gas pressure pushes the ellipsoid 7032 to squeeze the compression spring 7031, and the compression spring 7031 squeezes the extrusion block 7026. The extrusion block 7026 is inserted downward between the two rotating columns 7024. Due to its inverted cone shape, the rotating columns 7024 expand outward, driving the friction arc block 7023 to rotate around the hinge rod 7022 and expand outward.

[0067] The expanded friction arc block 7023 is in close contact with the inner wall of the friction disc 8062 at the end of the deceleration rod 806, generating frictional force. This frictional force decelerates the deceleration rod 806. The clamping rod A8061 on the deceleration rod 806 is inserted into the right-angled hole 8051 of the movable sleeve 805, so the deceleration rod 806 drives the movable sleeve 805 to decelerate. Also, because the clamping rod B407 at the output end of the driving mechanism 4 is inserted into the clamping groove 8052 of the movable sleeve 805, the deceleration of the movable sleeve 805 further decelerates the output end of the driving mechanism 4, ultimately achieving the deceleration and braking of the stamping module 5.

[0068] When the pneumatic component 701 or the air supply mechanism fails, the gas in the air passage 7011 disappears, and the compression spring 7031 releases kinetic energy, pushing the ellipsoid 7032 and the ejector pin 7033 out along the air passage 7011. The ejector pin 7033 impacts the trigger rod 801 inserted into the fine hole 7014, and the trigger rod 801 drives the inclined rod 803 to rotate around the fixed rod 802.

[0069] When the diagonal rod 803 rotates, the collar 804 connected to it will move accordingly, and the position of the movable sleeve 805 rotatably inserted on the collar 804 will also change. The movement of the movable sleeve 805 causes the card slot 8052 to disengage from the card rod B407, directly disconnecting the output end of the drive mechanism 4 from the movable sleeve 805. The output end of the drive mechanism 4 idles and cannot transmit the rotational force to the deceleration rod 806. The disconnection of the deceleration rod 806 enables the stamping module 5 to achieve braking, allowing the stamping module 5 to stop moving within an extremely short time, effectively avoiding serious safety accidents caused by equipment out of control and ensuring the personal safety of the operator and the integrity of the equipment.

[0070] In the present invention, by making the output end of the drive mechanism 4 idle in an emergency, damage to the equipment caused by the huge impact force generated by forced braking is avoided. Traditional emergency braking methods may cause damage to the transmission components, connection components, etc. of the equipment due to excessive instantaneous braking force, while this disconnection-type emergency braking method can effectively reduce this risk and extend the service life of the equipment.

[0071] As another embodiment of the present invention, the drive mechanism 4 includes a motor 401, a belt 402, a rotating shaft 403, a gear A404, a gear B405, and an output shaft 406. The motor 401 is provided on the back of the bracket 2, the rotating shaft 403 is rotatably inserted on the bracket 2, one end of the belt 402 is connected to the output end of the motor 401, the other end of the belt 402 is connected to the rotating shaft 403, the gear A404 is fixedly connected to the end of the rotating shaft 403 away from the belt 402, the output shaft 406 is rotatably inserted on the bracket 2, the gear B405 is fixedly connected to one end of the output shaft 406, the gear B405 is fixedly connected to the other end of the output shaft 406, the gear A404 is meshed and connected with the gear B405, and the end of the output shaft 406 away from the gear B405 is inserted into the emergency braking mechanism 8. When the motor 401 is started, the output end of the motor 401 starts to rotate. Since one end of the belt 402 is connected to the output end of the motor 401 and the other end is connected to the rotating shaft 403, the rotation of the motor 401 is transmitted to the rotating shaft 403 through the belt 402, causing the rotating shaft 403 to rotate accordingly. The gear A404 is fixedly connected to the end of the rotating shaft 403 away from the belt 402, so the gear A404 will rotate together with the rotating shaft 403. Also, because the gear A404 is meshed and connected with the gear B405 fixed on the output shaft 406, the rotation of the gear A404 will drive the gear B405 to rotate, and then drive the output shaft 406 to rotate.

[0072] The end of the output shaft 406 away from the gear B405 is inserted into the movable sleeve 805 of the emergency braking mechanism 8. Due to the cooperation of the card rod B407 and the card slot 8052, the rotation of the output shaft 406 is transmitted to the deceleration rod 806 through the movable sleeve 805, and finally drives the stamping module 5 to perform stamping work.

[0073] Working principle: This embodiment provides a pneumatic emergency braking device for a stamping equipment. First, when the stamping equipment is running normally, the motor 401 starts, and the output end of the motor 401 rotates, driving the rotating shaft 403 to rotate through the belt 402. Since the gear A404 is fixed on the rotating shaft 403, the gear A404 rotates accordingly. Also, because the gear A404 meshes with the gear B405, the output shaft 406 is driven to rotate. The latch B407 of the output shaft 406 is inserted into the card slot 8052 of the movable sleeve 805, so the movable sleeve 805 rotates along with it. The movable sleeve 805 is connected to the deceleration lever 806 through the latch A8061, thereby driving the deceleration lever 806 to rotate, and finally enabling the stamping module 5 to perform stamping work.

[0074] When decelerating and braking, the external air supply mechanism delivers gas to the L-shaped air duct 7011 through the air inlet hole 7012. The gas generates pressure in the air duct 7011, pushing the ellipsoid 7032 to squeeze the compression spring 7031. The compression plate 7034 at one end of the compression spring 7031 slides along the inclined surface 7028 of the extrusion block 7026, transmitting the force to the extrusion block 7026, causing the extrusion block 7026 to move downward against the pulling force of the tension spring B7027. The bottom end of the extrusion block 7026 is in an inverted cone shape and is inserted between the two rotating columns 7024, forcing the rotating columns 7024 to expand outward, driving the friction arc block 7023 to rotate around the hinge rod 7022 and expand outward, stretching the tension spring A7025. The expanded friction arc block 7023 is in close contact with the inner wall of the friction disk 8062, generating frictional force, causing the friction disk 8062 and the deceleration lever 806 connected thereto to decelerate. The deceleration lever 806 decelerates the output shaft 406 through the movable sleeve 805. The deceleration of the output shaft 406 affects the load of the motor 401 through the gear B405, gear A404, rotating shaft 403, and belt 402, achieving the deceleration of the entire drive mechanism 4, and further decelerating and braking the stamping module 5.

[0075] When the pneumatic component 701 or the air supply mechanism fails, the gas in the air duct 7011 disappears, and the compression spring 7031 releases kinetic energy, pushing the ellipsoid 7032 and the ejector pin 7033 out along the air duct 7011. The ejector pin 7033 impacts the trigger rod 801 inserted in the fine hole 7014, and the trigger rod 801 drives the inclined rod 803 to rotate around the fixed rod 802. When the inclined rod 803 rotates, the collar 804 connected thereto will move accordingly, and the position of the movable sleeve 805 rotatably inserted on the collar 804 will also change. The movement of the movable sleeve 805 causes the card slot 8052 to disengage from the latch B407, disconnecting the output shaft 406 from the movable sleeve 805. The output shaft 406 rotates idly and cannot transmit the rotational force to the deceleration lever 806, and the deceleration lever 806 stops rotating, achieving emergency braking of the stamping module 5.
