Description

Technical Field

[0001] This invention belongs to the technical field of automotive sheet metal gantry shearing devices, specifically relating to an automotive sheet metal gantry shearing device and its shearing method. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process mainly for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding / riveting / joining, forming, etc. It is widely used in the automotive processing field, such as the processing of car bodies. Products processed by sheet metal processing are sheet metal parts.

[0003] During the processing of some automotive sheet metal parts, a shearing device is required to cut the sheet metal parts into two smaller sections as needed. However, commonly used shearing devices can only perform the shearing function and cannot automatically load or unload the sheet metal parts. Usually, the sheet metal parts are continuously fed into the device manually, which makes the processing too reliant on manual labor and the shearing efficiency is also low. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention provides a gantry shearing device and method for automotive sheet metal parts. The gantry shearing device of this invention has a high degree of automation, requires almost no manual labor, greatly improves shearing efficiency, and can prevent the shearing blade from jumping and being damaged when encountering sheet metal parts with high hardness.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A gantry shearing device for automotive sheet metal parts includes a base, a sheet metal part moving assembly, and a shearing assembly located above the sheet metal part moving assembly. The sheet metal part moving assembly is mounted on the base, and the shearing assembly is arranged corresponding to the sheet metal part moving assembly. The shearing assembly is used to process the sheet metal parts on the sheet metal part moving assembly.

[0007] The sheet metal moving assembly includes a moving component X moving axis mounted on the base, a first driving component, and a clamping component slidably connected to the moving component X moving axis. The clamping component is used to clamp the sheet metal part, and the first driving component is used to drive the clamping component to move along the moving component X moving axis.

[0008] Furthermore, the shearing assembly includes a moving beam, guide rails, a second drive assembly, and a shearing head fixedly mounted on the moving beam. There are two guide rails arranged parallel to each other on the base. The guide rails are arranged along the Y-axis of the base. The two ends of the moving beam are slidably engaged with the guide rails. The moving beam can slide under the constraint of the two guide rails by the second drive assembly. The shearing head is fixed on one side of the moving beam and is located above the base.

[0009] Furthermore, the shearing head includes a shock-absorbing component, a hydraulic cylinder, a shearing blade, and guide rods. The shock-absorbing component is fixed to one side of the moving beam, and the hydraulic cylinder is fixed to the lower part of the shock-absorbing component. The end of the hydraulic cylinder away from the shock-absorbing component is the output end, and the output end is connected to the shearing blade. A limit plate is also installed on the end of the hydraulic cylinder away from the shock-absorbing component. There are two guide rods, which are vertically arranged and located on both sides of the hydraulic cylinder. One end of the guide rod passes through the limit plate and is fixed to the shearing blade.

[0010] Furthermore, the limiting plate extends away from the hydraulic cylinder on both sides to form a limiting structure.

[0011] Furthermore, the shock-absorbing assembly includes a rotating component, a first spring, a bottom mounting plate, and a push plate. The push plate and the bottom mounting plate are arranged opposite each other and parallel to each other. The rotating component is movably mounted on the side of the push plate away from the hydraulic cylinder. A connecting rod is connected to the rotating component away from the bottom mounting plate. The connecting rod is arranged parallel to the bottom mounting plate. Both ends of the connecting rod are respectively connected to the side of a telescopic cylinder. One end of each telescopic cylinder is fixed to the bottom mounting plate, and the other end is fixed to one side of the push plate. The connecting rod passes through the first spring. There are two first springs, which are correspondingly arranged on both sides of the rotating component, so that when the push plate is subjected to the force of the shearing blade, it can overcome the resistance of the first spring and move towards the bottom mounting plate.

[0012] Furthermore, the rotating component includes a rotating cylinder, a hinge rod, and a moving ring. The rotating cylinder is fixedly connected to the push plate. Two hinge rods are hinged to one end of the rotating cylinder away from the push plate. A moving ring is hinged to the other end of each of the two hinge rods. The moving ring is sleeved on the connecting rod and can move along the axis of the connecting rod. The sides of the hinge rings abut against a first spring, and the two hinge rods are angled together at an acute angle.

[0013] Furthermore, the telescopic cylinder is fitted with a second spring, one end of which abuts against one side of the push plate, and the second spring applies a force to the telescopic cylinder away from the push plate.

[0014] Furthermore, the clamping assembly includes a processing table, a clamping motor, and clamping plates. The processing table is slidably connected to the X-axis of the moving assembly via a connector. The processing table has a processing plane for placing sheet metal parts. A shearing blade can be moved from above to the processing plane. The processing plane has a shearing groove for the shearing blade to extend into. There are two clamping plates, which are slidably installed on the processing plane of the processing table. The two clamping plates are arranged opposite each other and are used to fix the sheet metal parts between them. The clamping motor is installed on one side of the processing table. The output end of the clamping motor is driven by a transmission screw, which is threadedly connected to the two clamping plates.

[0015] Furthermore, the first drive component and the second drive component can be a servo motor or a stepper motor.

[0016] Furthermore, this invention also claims protection for a shearing method employing the automotive sheet metal gantry shearing device described in any one of the above claims, comprising the following steps:

[0017] S1. Start the first drive component to move the processing table along the X-axis of the moving component to the feeding side of the base, place the sheet metal part on the processing table, and drive the clamping plate to fix the sheet metal part after the clamping motor is powered on.

[0018] S2. The first drive component moves the processing table along the X-axis of the moving component to the processing station on the base. The drive hydraulic cylinder moves the shearing blade toward the processing table for shearing. After shearing is completed, the drive hydraulic cylinder retracts the shearing blade.

[0019] S3. Restart the first drive component to move the processing table along the X-axis of the moving component to the discharge side of the base. The debris generated by shearing falls into the shearing groove. After shearing is completed, collect the sheet metal parts and clean the debris in the shearing groove.

[0020] S4. Start the first drive component to move the processing table along the X-axis of the moving component to the processing station on the base, and wait for the next shearing.

[0021] Compared with existing technologies, the beneficial effects of this solution are:

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] A gantry shearing device for automotive sheet metal parts, such as Figure 1 and Figure 2As shown, it includes a base 1, a sheet metal moving assembly 2, and a shearing assembly 3 located above the sheet metal moving assembly 2. The sheet metal moving assembly 2 is mounted on the base 1, and the shearing assembly 3 is arranged corresponding to the sheet metal moving assembly 2. The shearing assembly 3 is used to process the sheet metal parts on the sheet metal moving assembly 2.

[0032] The sheet metal moving assembly 2 includes a moving component X moving axis mounted on the base 1, a first driving component 22, and a clamping component 23 slidably connected to the moving component X moving axis. The clamping component 23 is used to clamp the sheet metal part, and the first driving component 22 is used to drive the clamping component 23 to move along the moving component X moving axis.

[0033] According to a specific embodiment of the present invention, the base 1 is a plate structure, with one side of the base 1 designated as the feeding side and the other side of the base 1 opposite to the feeding side designated as the discharging side. A processing station is also provided on the base 1, which can be located below the shearing assembly 3. The sheet metal moving assembly 2 is used to move the sheet metal part from the feeding side of the base 1 to the processing station for shearing, and then move the processed sheet metal part to the discharging side of the base 1. Specifically, the length of the moving assembly X-axis corresponds to the width of the base 1, and the clamping assembly 23 is used to clamp and fix the sheet metal part. The clamping assembly 23 moves along the moving assembly X-axis under the action of the first driving assembly 22. The present invention installs the moving assembly X-axis on the base 1 and drives the clamping assembly 23 to move via the first driving assembly 22, thereby solving the technical problem that the existing shearing device cannot automatically load and unload sheet metal parts. Through the automatic loading and unloading processing method, the present invention improves the efficiency of shearing processing.

[0034] Furthermore, such as Figure 3 As shown, the shearing assembly 3 includes a moving beam 31, guide rails 32, a second drive assembly 33, and a shearing head 34 fixedly mounted on the moving beam 31. There are two guide rails 32 arranged parallel to each other on the base 1, along the Y-axis of the base 1. The two ends of the moving beam 31 slide against the guide rails 32. The moving beam 31 can slide under the constraint of the two guide rails 32 via the second drive assembly 33. The shearing head 34 is fixed to one side of the moving beam 31 and is located above the base 1. The position on the base 1 corresponding to the shearing head 34 is a processing station. A processing seat 11 can be installed at the processing station. The function of the processing seat 11 is to allow the clamping assembly 23 to be better placed on the processing seat 11.

[0035] According to a specific embodiment of the present invention, a connecting plate can be fixed on one side of the moving beam 31. The connecting plate is used to connect and install the shear head 34. The shear head 34 can be set in the middle of the moving beam 31. The guide rail 32 is set along the Y-axis direction of the base 1. The guide rail 32 is located at the edge of the base 1. A slide rail is provided on the upper part of the guide rail 32. The slide groove at the end of the moving beam 31 is slidably connected to the corresponding slide rail. The shear head 34 can move in the Y-axis direction of the base 1, so that the shear head 34 can be adjusted in position according to the clamping assembly 23 for precise shearing.

[0036] Furthermore, the shear head 34 includes a shock-absorbing component, a hydraulic cylinder 344, a shearing blade 345, and guide rods 346. The shock-absorbing component is fixed to one side of the moving beam 31, and the hydraulic cylinder 344 is fixed to the lower part of the shock-absorbing component. The end of the hydraulic cylinder 344 away from the shock-absorbing component is the output end, and the output end is connected to the shearing blade 345. A limit plate 347 is also installed at the end of the hydraulic cylinder 344 away from the shock-absorbing component. There are two guide rods 346, which are vertically arranged and located on both sides of the hydraulic cylinder 344. One end of the guide rod 346 passes through the limit plate 347 and is fixed to the shearing blade 345.

[0037] According to a specific embodiment of the present invention, a specific structure of a shearing head 34 is provided. A shock-absorbing component is used to protect the shearing head 34 blade during shearing. The shock-absorbing component is located at the upper end of the shearing head 34, and a hydraulic cylinder 344 is installed at the lower part of the shock-absorbing component. The output end of the hydraulic cylinder 344 drives the shearing blade 345 to move up and down. A guide rod 346 is vertically arranged on both sides of the hydraulic cylinder 344. The end of the guide rod 346 is fixed to the upper part of the shearing blade 345. The guide rod 346 is used to limit the up and down movement of the shearing blade 345 and prevent the shearing blade 345 from lateral jumping during shearing.

[0038] Furthermore, such as Figure 4 As shown, the shock-absorbing assembly includes a rotating component 35, a first spring 341, and a bottom mounting plate 342 push plate 343. The push plate 343 and the bottom mounting plate 342 are arranged opposite to each other and parallel to each other. The rotating component 35 is movably mounted on the side of the push plate 343 away from the hydraulic cylinder 344. A connecting rod 353 is connected to the rotating component 35 away from the bottom mounting plate 342. The connecting rod 353 is arranged parallel to the bottom mounting plate 342. Both ends of the connecting rod 353 are respectively connected to the side of a telescopic cylinder 351. One end of each telescopic cylinder 351 is fixed to the bottom mounting plate 342, and the other end is fixed to one side of the push plate 343. The connecting rod 353 passes through the first spring 341. There are two first springs 341, which are correspondingly arranged on both sides of the rotating component 35, so that when the push plate 343 is subjected to the force of the shearing blade 345, it can overcome the resistance of the first spring 341 and move towards the bottom mounting plate 342.

[0039] According to a specific embodiment of the present invention, this embodiment provides a specific structure for a shock-absorbing component. A bottom mounting plate 342 is fixed to a connecting plate on one side of a moving beam 31. The bottom mounting plate 342 has an "L"-shaped structure for easy installation. Two telescopic cylinders 351 are fixed to one side of the bottom mounting plate 342. The end of the telescopic cylinder 351 away from the bottom mounting plate 342 is connected to one side of a push plate 343. The push plate 343 is bolted to the upper part of a hydraulic cylinder 344. A rotating component 35 is used to move the hydraulic cylinder 344 and transmit the movement to the first spring 341 for compression. If the force on the shearing blade 345 exceeds its limit, the hydraulic cylinder 344 will compress the first spring 341 and the second spring 357 after operation, thereby protecting the shearing blade 345.

[0040] Furthermore, the rotating component 35 includes a rotating cylinder 354, a hinge rod 355, and a moving ring 356. The rotating cylinder 354 is fixedly connected to the push plate 343. Two hinge rods 355 are hinged to one end of the rotating cylinder 354 away from the push plate 343. A moving ring 356 is hinged to the other end of each of the two hinge rods 355. The moving ring 356 is sleeved on the connecting rod 353 and can move along the axis of the connecting rod 353. The sides of the hinge rings abut against a first spring 341, and the two hinge rods 355 are angled together at an acute angle.

[0041] Furthermore, the telescopic cylinder 351 is fitted with a second spring 357, one end of which abuts against one side of the push plate 343. The second spring 357 applies a force to the telescopic cylinder 351 away from the push plate 343. Due to the high hardness of the sheet metal parts, the shearing blade 345 also bears a relatively large force. The first spring 341 and the second spring 357 work together to enhance the buffering capacity of the shock absorption assembly.

[0042] Furthermore, such as Figure 5 As shown, the clamping assembly 23 includes a processing table 231, a clamping motor 232, and clamping plates 233. The processing table 231 is slidably connected to the moving assembly X-axis via a connector. The processing table 231 has a processing plane 234 for placing sheet metal parts. A shearing blade 345 can move from the top to the processing plane 234. The processing plane 234 has a shearing groove 235 for the shearing blade 345 to extend into. There are two clamping plates 233, which are slidably installed on the processing plane 234 of the processing table 231. The two clamping plates 233 are arranged opposite each other and are used to fix the sheet metal parts between them. The clamping motor 232 is installed on one side of the processing table 231. The output end of the clamping motor 232 is connected to a transmission screw, which is threadedly connected to the two clamping plates 233.

[0043] The upper part of the processing table 231 has a limiting head 236. The length of the limiting head 236 of the processing table 231 is matched with the structure of the limiting plate 347. The middle part of the limiting head 236 has a groove structure so that the shearing blade 345 can extend into it. The limiting structures on both sides of the limiting plate 347 are used for positioning the shearing blade 345. When the processing table 231 moves along the X-axis of the base 1, the limiting structures on both sides of the limiting plate 347 are located on both sides of the processing table 231, so that the processing table 231 can be located inside the limiting plate 347. Thus, when the shearing blade 345 is driven by the hydraulic cylinder 344 to descend, the shearing blade 345 can accurately extend into the shearing groove 235 opened in the processing plane 234.

[0044] The side of the processing table 231 away from the clamping motor 232 is slidably connected to the moving component X moving axis via the connecting column 24. A groove is opened in the middle of the processing table 231 to form a processing plane 234 for placing sheet metal parts. The processing plane 234 is located below the limit head 236. The transmission screw (not visible in the figure) is threadedly connected to the two clamping plates 233. When installing the clamping plates 233, the position of the clamping plates 233 on the transmission screw can be selected to match sheet metal parts of different sizes. Under the action of the clamping motor 232, the two clamping plates 233 will move closer or further away from each other to clamp or release the sheet metal parts.

[0045] The automotive sheet metal gantry shearing device of the present invention has a high degree of automation, requires almost no manual labor, greatly improves shearing efficiency, and can prevent the shearing blade 345 from jumping and being damaged when encountering sheet metal parts with high hardness.

[0046] Furthermore, the first drive component 22 and the second drive component 33 can be servo motors or stepper motors. Servo motors offer high precision movement and are suitable for precision machining.

[0047] Furthermore, this invention also claims protection for a gantry shearing method for automotive sheet metal parts, employing any one of the aforementioned gantry shearing devices for automotive sheet metal parts, comprising the following steps:

[0048] S1. Start the first drive component 22 to move the processing table 231 along the X-axis of the moving component to the feeding side of the base 1, place the sheet metal part on the processing table 231, and drive the clamping plate 233 to fix the sheet metal part after the clamping motor 232 is powered on.

[0049] S2. The first drive component 22 drives the processing table 231 to move along the X-axis of the moving component to the processing station of the base 1, and drives the hydraulic cylinder 344 to move the shearing blade 345 to the processing table 231 for shearing. After shearing is completed, the hydraulic cylinder 344 retracts the shearing blade 345.

[0050] S3. Restart the first drive component 22 to move the processing table 231 along the X-axis of the moving component to the discharge side of the base 1. The debris generated by shearing falls into the shearing groove 235. After shearing is completed, the sheet metal part is collected and the debris in the shearing groove 235 is cleaned.

[0051] S4. Start the first drive component 22 to move the processing table 231 along the X-axis of the moving component to the processing station of the base 1, and wait for the next shearing.
