Description

Technical Field

[0001] This utility model relates to the technical field of straight profile forming, and in particular to a follow-up punching equipment with an anti-collision protection system and a straight profile production line. Background Technology

[0002] In the multi-station processing system for straight profiles, see the invention patent with patent number 202311701395.3. The punching unit needs to move synchronously with the straight profile and perform the punching operation. Under normal circumstances, the punching unit can smoothly perform the punching operation and move out of the hole.

[0003] However, if the punching unit and the straight profile do not move synchronously, the punching unit may get stuck in the hole and be unable to punch smoothly and / or move out. In this case, the punching unit will often stop automatically under the action of the sensor, but the straight profile cannot stop immediately. This causes the straight profile to hit the punch of the impact mechanism, which in severe cases can lead to the breakage of the punch or the straight profile. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a follow-up punching device with an anti-collision protection system, which solves the technical problem in the prior art where the movement of the punching unit and the straight profile is not synchronized, causing the straight profile to hit the punch of the impact mechanism after the punching unit stops, resulting in the punch or the straight profile breaking.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] In a first aspect, this utility model provides a follow-up punching device with an anti-collision protection system. The follow-up punching device includes a base, a plurality of sliding units supported on the base, and punching units supported one-to-one on the sliding units. The anti-collision protection system includes a limiting member and an overload protection device. The limiting member is supported on the base. When the straight profile drives the punching unit to move relative to the base, the stop surface of the limiting member receives the impact force from the base of the punching unit and transmits the impact force to the base. The overload protection device is supported on the foundation and connected to the base. When the impact force transmitted to the overload protection device is greater than the trigger threshold of the overload protection device, the overload protection device can deform or break to buffer the impact force received by the base.

[0009] Secondly, this utility model provides a straight profile production line, including the follow-up punching equipment with an anti-collision protection system as described in the above technical solution, and also includes a straight profile forming system located upstream of the follow-up punching equipment with an anti-collision protection system.

[0010] (III) Beneficial Effects

[0011] The beneficial effects of this utility model are as follows: The follow-up punching equipment and straight profile production line with anti-collision protection system of this utility model aim to ensure the safety and stability of the equipment during the follow-up punching process. The base serves as the supporting foundation for the entire equipment and is supported on the ground. The sliding unit is installed on the base, providing the punching unit with horizontal movement capability. In conjunction with the control system, the punching unit can perform follow-up punching of straight profiles without stopping the feed, thereby greatly improving the punching efficiency of straight profiles.

[0012] The limiting component is mounted on the base and is designed to promptly absorb the impact force from the base of the punching unit after it has moved forward to a predetermined position due to an impact from the straight profile. The limiting component effectively absorbs and disperses the impact force and safely transfers it to the base.

[0013] The overload protection device is supported on the foundation and connected to the base, forming an additional safety barrier. When the impact force transmitted to the overload protection device through the base exceeds its preset trigger threshold, the device will deform or break. This design aims to absorb and disperse excessive impact force by sacrificing the overload protection device, preventing irreversible damage to the punch and / or straight profile of the punching unit during operation of the straight profile, thereby improving the safety and stability of the straight profile punching process and reducing the processing cost of the straight profile.

[0028] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figure 1-5 This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" are used in this document. Figure 1 The orientation is taken as a reference, and the front is Figure 1 The direction from the center to the right.

[0029] Example 1:

[0030] Reference Figures 1-4 This utility model provides a follow-up punching device with an anti-collision protection system. The follow-up punching device includes a base 1, a plurality of sliding units 2 supported on the base 1, and punching units 3 supported on the sliding units 2 respectively. The anti-collision protection system includes a limiting member 4 and an overload protection device 5. The limiting member 4 is supported on the base 1. When the straight profile drives the punching unit 3 to move relative to the base 1, the stop surface of the limiting member 4 receives the impact force from the base of the punching unit 3 and transmits the impact force to the base 1. The overload protection device 5 is connected to the base 1. When the impact force transmitted to the overload protection device 5 is greater than the trigger threshold of the overload protection device 5, the overload protection device 5 can deform or break to buffer the impact force received by the base 1.

[0031] In this embodiment, the design of the follow-up punching equipment with an anti-collision protection system aims to ensure the safety and stability of the equipment during the follow-up punching process. The base 1 serves as the supporting foundation for the entire equipment, resting on the ground. The sliding unit 2 is installed on the base 1, providing the punching unit 3 with horizontal movement capability. In conjunction with the control system, the punching unit 3 can perform follow-up punching on straight profiles without stopping the feed, thereby greatly improving the punching efficiency of straight profiles.

[0032] The limiting member 4 is installed on the base 1. Its design purpose is to promptly absorb the impact force from the base of the punching unit 3 after the punching unit 3 moves forward to the predetermined position due to the impact from the straight profile. The limiting member 4 can effectively absorb and disperse the impact force and safely transfer it to the base 1.

[0033] The overload protection device 5 is supported on the foundation and connected to the base 1, forming an additional safety barrier. When the impact force transmitted to the overload protection device 5 through the base 1 exceeds its preset trigger threshold, the device will deform or break. This design aims to absorb and disperse excessive impact force by sacrificing the overload protection device 5, thus preventing irreversible damage to the punch and / or straight profile of the punching unit 3 during operation of the straight profile. This improves the safety and stability of the straight profile punching process and reduces the processing cost of the straight profile.

[0034] Example 2:

[0035] Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0036] When the impact force transmitted to the overload protection device 5 exceeds the trigger threshold of the overload protection device 5, the connection between the overload protection device 5 and the base 1 fails, and the base 1 is allowed to move forward.

[0037] In this embodiment, the deformation or breakage of the overload protection device 5 not only buffers the impact force, but also causes the connection between the overload protection device 5 and the base 1 to fail, thereby allowing the base 1 to move forward. As a result, the punching unit 3, driven by the straight profile, has a longer driving time and a longer driving stroke. Thus, when the punching unit 3 decelerates the straight profile, the straight profile will also have a longer deceleration stroke and a longer deceleration time, thereby further reducing the risk of damage to the straight profile and / or the punch.

[0038] At the same time, as the base 1 moves forward, it can further dissipate the impact energy, thereby making the impact force more fully buffered.

[0039] Example 3:

[0040] Reference Figure 1 and Figure 4 In addition to possessing all the technical solutions of Embodiment 2 described above, the embodiments of this utility model further possess the following technical solutions:

[0041] The overload protection device 5 includes a fixed base 51, a connecting rod 52, a locking block 53, and a locking groove 54. The fixed base 51 is detachably connected to the foundation. The connecting rod 52 extends along the running direction of the straight profile and is detachably connected to the fixed base 51. One end of the connecting rod 52 forms a locking block 53. The locking groove 54 is detachably connected to the base 1, and the locking block 53 is engaged in the locking groove 54. At least one of the locking block 53, the locking groove 54, the fixed base 51, and the connecting rod 52 can deform or break when the base 1 moves relative to the foundation.

[0042] In this embodiment, the fixed base 51 serves as the foundation of the entire overload protection device 5, and is fixed on the foundation to provide stable support. The fixed base 51 and the foundation are configured to be detachably connected by bolts to facilitate installation, maintenance and replacement.

[0043] The connecting rod 52 extends along the running direction of the straight profile to ensure consistency with the movement direction of the equipment, and can directly withstand and transmit impact forces. The connecting rod 52 is detachably connected to the fixed base 51 for easy adjustment or replacement as needed.

[0044] One end of the connecting rod 52 forms a locking block 53, which is used to cooperate with the locking slot 54 to realize the key connection point for overload protection. The locking slot 54 is detachably connected to the base 1 and corresponds to the locking block 53, together forming the main part of the overload protection mechanism.

[0045] During normal operation of the follow-up punching equipment, the base 1 is securely connected to the foundation via the overload protection device 5. However, when the impact force transmitted to the overload protection device 5 exceeds its trigger threshold, the overload protection device 5 will activate, causing at least one of the following components to deform or break: the locking block 53, the locking groove 54, the fixing seat 51, and the connecting rod 52. This process is designed to absorb and disperse the impact force through stress concentration and fracture mechanisms in the materials.

[0046] The materials of the locking block 53, locking slot 54, fixing seat 51, and connecting rod 52 should have good mechanical properties and toughness, capable of undergoing controlled deformation or fracture while withstanding a certain impact force. The dimensions and fitting precision of each component should be strictly controlled to ensure stable connection under normal conditions and smooth disengagement or breakage under abnormal conditions. The entire overload protection device 5 should be designed for easy disassembly, installation, and maintenance, so as to quickly replace damaged parts when necessary.

[0047] Preferably, the slot 54 can deform or break when the base 1 moves relative to the foundation, so that the locking block 53 is disengaged from the slot 54; the locking block 53 is a flange connected to one end of the connecting rod 52, and the slot 54 forms a receiving groove that matches the shape of the flange.

[0048] In this embodiment, it is preferable that the slot 54 experiences a structural failure, which, while buffering the impact, disconnects the connection between the overload protection device 5 and the base 1. At the same time, the flange and the receiving groove are designed to fit together, so when connecting the overload protection device 5 and the base 1, the slot 54 can be fitted onto the flange and then bolted to the base 1, ensuring the convenience of the assembly process.

[0049] In this embodiment, the fixed base 51 includes a base plate 511 and an upright plate 512 connected to the base plate 511, and the connecting rod 52 passes through the upright plate 512; the overload protection device 5 also includes two sets of connecting nuts 55, which are threaded to the connecting rod 52 and are located on both sides of the upright plate 512 along the axis of the connecting rod 52, so as to lock the connecting rod 52 onto the upright plate 512.

[0050] In this embodiment, the fixing base 51 mainly includes a base plate 511 and a vertical plate 512, wherein the vertical plate 512 is vertically connected to the base plate 511, forming a stable support structure. One of the core components of the overload protection device 5 is the connecting rod 52, which runs through the vertical plate 512 and becomes a key component for connecting and transmitting force. To ensure that the connecting rod 52 is stably positioned on the vertical plate 512 and will not loosen due to force, the connecting nut 55 is threadedly connected to the connecting rod 52 and is located on both sides of the vertical plate 512 along the axial direction of the connecting rod 52, so that the connecting nut 55 can act as a locking device to tightly lock the connecting rod 52 onto the vertical plate 512, maintaining the stability of the connection even when subjected to large external forces.

[0051] Example 4:

[0052] Reference Figure 2 and Figure 3 In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0053] The limiting member 4 has a stress zone 40. When the impact force on the limiting member 4 is greater than the strength threshold of the stress zone 40, the limiting member 4 will deform or break at the stress zone 40.

[0054] In this embodiment, a stress zone 40 is designed on the limiting member 4 so that it can break or deform when subjected to excessive impact force. In this way, when the impact force of the base of the punching unit 3 on the limiting member 4 is too large, the impact transmitted from the limiting member 4 to the base 1 is reduced, thereby reducing the impact force on the anti-collision protection device and enabling the entire system to better buffer the impact force from the straight profile on the impact unit.

[0055] Example 5:

[0056] In addition to possessing all the technical solutions of Embodiments 1 and 4 described above, the embodiments of the utility model further possess the following technical solutions:

[0057] The trigger threshold of stress zone 40 is greater than the trigger threshold of overload protection device 5 and the fracture threshold of punch in punching unit 3.

[0058] In this embodiment, the trigger threshold of the overload protection device 5 is designed to be lower than the trigger threshold of the stress zone 40 of the limiting member 4. This means that when an overload occurs, the overload protection device 5 should respond first, rather than waiting for the limiting member 4 to break. This ensures that the limiting member 4 only buffers the impact force through structural failure when the impact force on the punching unit 3 is too large. This guarantees the reliability of the system in buffering impact force while also effectively controlling the maintenance cost of the components, thus significantly improving the safety and reliability of the system. Designing the trigger thresholds of the stress zone 40 and the overload protection device 5 to be greater than the fracture threshold of the punch of the punching unit 3 ensures that the stress zone 40 and the overload protection device 5 act as buffers before the punch of the punching unit 3 breaks, guaranteeing the safety and reliability of the system.

[0059] Example 6:

[0060] Reference Figure 1 and Figure 5 In addition to possessing all the technical solutions of Embodiment 2 described above, the embodiments of this utility model further possess the following technical solutions:

[0061] The anti-collision protection system also includes a sliding device 6, and the base 1 is supported on the foundation by the sliding device 6.

[0062] In this embodiment, the base 1 is configured to be slidably supported on the foundation by the sliding device 6. This ensures that after the overload protection device 5 takes effect and disconnects from the base 1, the base 1 can slide forward, thereby further releasing the impact force on the base 1 and further preventing damage to the straight profile or punch, thus improving the reliability of the system.

[0063] Preferably, the sliding device 6 includes a track 61 fixed on the foundation and a roller 62 rotatably connected to the base 1 along the width direction of the base 1. The roller 62 can match the track 61. The outer surfaces of the track 61 and the roller 62 are friction surfaces.

[0064] In this embodiment, a sliding connection between the base 1 and the foundation is established by the cooperation of the track 61 and the roller 62. Since the roller 62 and the track 61 are friction surfaces, when they slide relative to each other, they will further dissipate the impact energy through friction, thereby better absorbing the impact force on the base 1, and further avoiding damage to the straight profile or punch, thus improving the reliability of the system.

[0065] Specifically, the track 61 can be set as an angle steel fixedly connected to the foundation, and the rollers 62 are evenly distributed on the bottom surface of the base 1 to ensure the stability of the base 1 when it slides.
