Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and more specifically, to a slide block device for a stamping machine and a stamping machine. Background Technology

[0002] In the automotive industry, stamping line presses use molds to process sheet metal into body parts with specific shapes. The mold body is mainly divided into an upper mold and a lower mold. During the stamping process, the press separates the upper and lower molds. The lower mold remains stationary, while the upper mold moves up and down with the press to form the stamping process. To produce different versions of parts, the upper mold is generally equipped with pneumatic components. For some parts, an air source needs to be connected to the pneumatic components in the upper mold to switch the working state of the upper mold. In existing technology, there are generally two ways to connect the air source to the upper mold. One is to set an air source interface on the upper slide, and connect a set of flexible air pipes through the interface to the upper mold. The other is not to set an air source on the upper slide, but instead to run a set of air pipes from the lower worktable of the press to the upper mold. When using the first method to install the air pipes, the mold needs to be moved into the press along with the worktable, then the press needs to be pressed down to fit the mold, the slide needs to clamp the mold, and the press needs to be stopped before personnel can enter the press to work. This process involves time loss and the risk of safety accidents during operation. When the air pipe is connected in the second way, it will move up and down along with the upper slide and upper die during the stamping operation. In this process, there is a risk that the air pipe will scrape against other objects and collide with the conveying device that enters and exits the press. Utility Model Content

[0003] To address the safety risks and time-consuming issues associated with existing upper mold air pipe connection structures, this invention provides a press upper slide block device and press itself. This eliminates the need for manual connection of the air path between the upper slide block and the upper mold, improving installation efficiency. Furthermore, the air path is concealed within the upper slide block and upper mold, preventing it from scraping against external objects or operating equipment, thus eliminating safety risks.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a punch press upper slide device, including an upper slide, an upper die detachably mounted on the bottom surface of the upper slide, a pneumatic component disposed inside the upper die, a first gas interface disposed on the bottom surface of the upper slide, a second gas interface disposed on the upper surface of the upper die, the first gas interface and the second gas interface being detachably connected, a first air passage disposed inside the upper slide, the two ends of the first air passage being connected to an external air source and the first gas interface respectively, and the second gas interface being connected to the pneumatic component through the second air passage.

[0005] In this technical solution, an upper die is detachably mounted on the bottom surface of the upper slide block, allowing operators to remove and replace it as needed. The upper die contains pneumatic components for switching working states; these components require an air supply to function properly. The upper surface of the upper die faces the upper slide block of the press, and a second gas port is located on this surface. The bottom surface of the upper slide block faces the upper surface of the upper die, and a first gas port is located on this surface. The second gas port corresponds vertically to the first gas port. To ensure normal operation of the stamping process, the upper die needs to be fixed in a fixed position on the upper slide block; therefore, the relative positions of the first gas port on the upper slide block and the second gas port on the upper die remain constant. When the upper slide block is installed on the upper die, the upper die is simply placed in a designated position below the upper slide block, and the press is controlled to drive the upper slide block to press against the upper die. When the upper slide block reaches the press-fit position with the upper die, the first and second gas ports connect precisely, and the upper slide block remains stationary until the upper die is securely installed on the upper slide block. In this process, the connection between the first and second gas interfaces is completed during the installation of the upper mold on the upper slide block, enabling the air passage between the upper slide block and the upper mold to be connected. No additional steps are needed to connect the upper mold to the air source, improving the installation efficiency of the upper mold and reducing the workload of workers. Furthermore, workers do not need to extend under the upper slide block during the entire process, avoiding potential safety hazards. The first gas interface in the upper slide block is connected to an external air source through a first air passage, while the second gas interface in the upper mold is connected to pneumatic components through a second air passage. The first and second air passages are respectively located inside the upper slide block and the upper mold. During stamping operations, the first or second air passage will not be exposed and scrape against external objects, operating equipment, or even intrude into the stamping channel, affecting normal stamping operations and causing problems such as defective stamped products, damage to stamping equipment, or air pipe breakage, thus improving the safety of stamping operations.

[0006] Preferably, the first gas interface includes an inner cylinder and an outer cylinder, the inner cylinder is connected to the first gas passage, the outer cylinder is sleeved on the outside of the inner cylinder, a groove is formed in the gap between the inner cylinder and the outer cylinder, the second gas interface is a tubular structure, the top end of the second gas interface is connected to the groove, a sealing ring is sleeved on the bottom of the groove, and the sealing ring abuts against the top of the second gas interface.

[0007] Preferably, the first airway is an air tube, which is detachably installed inside the upper slider.

[0008] Preferably, the bottom surface of the upper slider is provided with an installation groove, and the air pipe is detachably installed in the installation groove, wherein the depth of the installation groove is greater than the diameter of the air pipe.

[0010] Preferably, the mounting groove includes a shallow groove with a depth equal to the thickness of the cover plate. The air pipe is detachably installed in the deep groove. The bottom of the shallow groove has multiple threaded holes along the length of the mounting groove. The cover plate has multiple mounting holes on both sides along the length of the cover plate. The mounting holes correspond to the threaded holes. The mounting holes are located in the deep groove and the shallow groove. The shallow groove is arranged on both sides of the deep groove. The deep groove and the shallow groove are connected. A fastening bolt is also provided inside the shallow groove. The fastening bolt is inserted into the mounting hole and the threaded hole in sequence and is threadedly connected to the threaded hole.

[0011] Preferably, the upper slider has a through hole for gas to pass through, the through hole connecting the first gas interface to the external gas source, and the through hole is the first gas passage.

[0012] Preferably, the bottom surface of the upper slider is provided with a clamping groove, and at least two clamping grooves are provided. The two clamping grooves are respectively provided on opposite sides of the upper slider. A clamp is slidably mounted on the clamping groove. The lower end of the clamp protrudes inward to form a clamping part. The upper end of the upper mold protrudes outward to form a second clamping part. The clamping part can extend into the lower part of the second clamping part and abut against the bottom surface of the second clamping part. A driving device for driving the clamp to move is also provided inside the upper slider.

[0013] Preferably, multiple clamping grooves are provided on one side of the upper slider along the length of that side, and the number of clamping grooves on the other side of the upper slider is the same as the number of clamping grooves on that side.

[0014] This utility model also provides a stamping machine, including a lower die, a lower worktable of the press, a press, and the above-mentioned upper slide block device of the stamping machine.

[0015] In this technical solution, a press provides pressure for stamping, and the lower worktable of the press bears the stamping force. The lower die is mounted on the lower worktable of the press. The upper slide device of the press is installed on the drive end of the press, and the press can drive the upper slide device to move vertically. The upper and lower dies in the upper slide device are aligned vertically. During stamping, the raw material is first placed on the upper surface of the lower die, and then the press is started. The drive end of the press drives the upper slide device to press down on the lower die. Finally, the upper and lower dies of the upper slide device press the upper and lower surfaces of the material respectively, stamping the material into a preset shape. Then, the drive end of the press drives the upper slide device to move upward, causing the upper die to leave the stamped workpiece. Finally, an automatic conveying device removes the workpiece, completing the stamping process.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with a first gas interface and a second gas interface that can be plugged into each other.

This improves the installation efficiency of the upper die, reduces the labor load on workers, and prevents workers from needing to extend under the upper slide block during the entire process, thus avoiding safety hazards. The first and second gas pipes are respectively located inside the upper slide block and the upper die. During stamping operations, they will not be affected by external objects, running equipment, or even intrusion into the stamping channel, thus preventing problems such as defective stamped products, damage to stamping equipment, and damage to gas pipes, thereby improving the safety of stamping operations.

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0028] Example 1

[0029] like Figure 1As shown, a press upper slide device includes an upper slide 1, an upper die 2 detachably mounted on the bottom surface of the upper slide 1, a pneumatic component inside the upper die 2, a first gas inlet 3 on the bottom surface of the upper slide 1, and a second gas inlet 4 on the upper surface of the upper die 2. The first gas inlet 3 and the second gas inlet 4 are detachably connected. A first air passage is provided inside the upper slide 1, with its two ends connected to an air source and the first gas inlet 3, respectively. The second gas inlet 4 is connected to the pneumatic component through the second air passage. The upper die 2 is detachably mounted on the bottom surface of the upper slide 1, allowing operators to disassemble and replace it as needed. The pneumatic component in the upper die 2 is used to drive the upper die 2 to switch working states. The pneumatic component in the upper die 2 requires an air source to function properly. The upper surface of the upper die 2 faces the upper slide 1 of the press, and the second gas inlet 4 is located on this surface. The bottom surface of the upper slide 1 faces the upper surface of the upper die 2, and the first gas inlet 3 is located on this surface. The second gas inlet 4 corresponds vertically to the first gas inlet 3. To ensure the normal operation of the stamping process, the upper die 2 needs to be fixed in a fixed position on the upper slide block 1. Therefore, the relative positions between the first gas port 3 on the upper slide block 1 and the second gas port 4 on the upper die 2 can remain unchanged. When the upper slide block 1 is installed on the upper die 2, it is only necessary to place the upper die 2 in a predetermined position below the upper slide block 1 and control the stamping machine to drive the upper slide block 1 to press against the upper die 2. When the upper slide block 1 is pressed to the press-fit position between itself and the upper die 2, the first gas port 3 and the second gas port 4 are precisely inserted. Then, the upper slide block 1 remains stationary until the upper die 2 is securely installed on the upper slide block 1. In this process, the connection between the first gas port 3 and the second gas port 4 is completed during the installation of the upper die 2 on the upper slide block 1, realizing the connection of the air passage between the upper slide block 1 and the upper die 2. There is no need for additional procedures to connect the gas source to the upper die 2, which improves the installation efficiency of the upper die 2, reduces the labor load of workers, and avoids the safety hazards of workers not needing to reach under the upper slide block 1 during the entire process. The first gas interface 3 in the upper slide block 1 is connected to an external gas source through the first gas channel, and the second gas interface 4 in the upper mold 2 is connected to the pneumatic components through the second gas channel. The first gas channel and the second gas channel are respectively located inside the upper slide block 1 and the upper mold 2. During the stamping operation, the first or second gas channel will not be exposed to the outside and scrape against external objects, running equipment, etc., or even invade the stamping channel, affecting the normal stamping operation and causing problems such as defective stamped products, damage to stamping equipment, and air pipe breakage, thereby improving the safety of the stamping operation.

[0030] like Figure 3As shown, the first gas interface 3 includes an inner cylinder 31 and an outer cylinder 32. The inner cylinder 31 is connected to a gas pipe, and the outer cylinder 32 is sleeved on the outside of the inner cylinder 31. A groove 33 is formed in the gap between the inner cylinder 31 and the outer cylinder 32. The second gas interface 4 is a tubular structure. The top end of the second gas interface 4 is aligned with the groove 33. A sealing ring 34 is fitted at the bottom of the groove 33, and the sealing ring 34 abuts against the top end of the second gas interface 4. When the second gas interface 4 is aligned with the groove 33, the outer cylinder 32 restricts the position of the second gas interface 4. The inner wall of the outer cylinder 32 abuts against the outer wall of the second gas interface 4, thereby confining the second gas interface 4 inside the outer cylinder 32. This prevents the second gas interface 4 from moving significantly during use, which could cause the inner cylinder 31 to bend and compromise the sealing of the inner cylinder 31. Meanwhile, the inner cylinder 31, outer cylinder 32, and second gas interface 4 together form an inverted "U"-shaped gas passage. This causes gas to travel a longer distance when leaking from the connection between the first gas interface 3 and the second gas interface 4, thus buffering the leaking gas and enhancing the sealing performance. The sealing ring 34 is elastic. When the sealing ring 34 comes into contact with the second gas interface 4, the second gas interface 4 applies pressure to the sealing ring 34, causing the sealing ring 34 to deform. The deformed shape of the sealing ring 34 is the same as the shape of the second gas interface 4. When the two are joined together, there are no gaps, thus achieving a sealing effect and preventing gas leakage at that point.

[0031] like Figure 1 As shown, the first airway is the air tube 6, which is detachably installed inside the upper slider 1. An external air source can be input to the first gas interface 3 through the air tube 6. During daily use, the operator can remove the air tube 6 from the upper slider 1 for cleaning, inspection, or replacement.

[0032] like Figure 2 As shown, the bottom surface of the upper slider 1 is provided with an installation groove 5, and the air pipe 6 can be detachably installed in the installation groove 5. The depth of the installation groove 5 is greater than the diameter of the air pipe 6. By providing the installation groove 5, a space is formed inside the upper slider 1 to accommodate the air pipe 6, which prevents the air pipe 6 from protruding from the surface of the upper slider 1 and affecting normal stamping operations. Furthermore, workers can quickly inspect, repair, and replace the air pipe 6 through the installation groove 5, thus improving the work efficiency of the workers.

[0033] like Figure 2 As shown, a cover plate 7 is also provided. The cover plate 7 is arranged along the length of the mounting groove 5. The cover plate 7 is detachably installed at the opening of the mounting groove 5, and the cover plate 7 closes the opening of the mounting groove 5. The bottom surface of the cover plate 7 is flush with the bottom surface of the upper slider 1. By setting the cover plate 7 to close the mounting groove 5, it is ensured that the air pipe 6 will not fall out of the mounting groove 5 during stamping, thus ensuring the safety of the stamping process. When it is necessary to inspect, repair, or replace the air pipe 6, it is only necessary to remove the cover plate 7.

[0034] like Figure 4 As shown, the mounting groove 5 includes a deep groove 51 and a shallow groove 52. The shallow groove 52 is arranged on both sides of the deep groove 51, and the deep groove 51 and the shallow groove 52 are connected. The depth of the shallow groove 52 is the same as the thickness of the cover plate 7. The air pipe 6 is detachably installed in the deep groove 51. The bottom of the shallow groove 52 is provided with multiple threaded holes along the length of the mounting groove 5. The two sides of the cover plate 7 are provided with multiple mounting holes along the length of the cover plate 7. The mounting holes and threaded holes are positioned correspondingly. Fastening bolts are also provided in the mounting holes. The fastening bolts are inserted into the mounting holes and threaded holes in sequence and are threadedly connected to the threaded holes. The deep groove 51 is used to accommodate the air pipe 6, and the shallow groove 52 is used to install the cover plate 7. On the one hand, this prevents the cover plate 7 from protruding from the bottom surface of the upper slider 1 and affecting the installation of the upper mold 2. On the other hand, the bottom of the shallow groove 52 abuts against the cover plate 7 to prevent the cover plate 7 from excessively intruding into the mounting groove 5 and causing pressure on the air pipe 6, thus affecting the air supply capacity of the air pipe 6. The cover plate 7 is installed in the shallow groove 52 by fastening bolts and mounting holes and threaded holes. When in use, the cover plate 7 can be installed and removed simply by tightening and loosening the fastening bolts. The installation and removal process is simple and quick.

[0035] like Figure 2 , 5 As shown in Figure 6, the bottom surface of the upper slider 1 is provided with clamping grooves 11. At least two clamping grooves 11 are provided, each located on opposite sides of the upper slider 1. Clamps 12 are slidably mounted on the clamping grooves 11. The lower end of the clamps 12 protrudes inward from the upper slider 1 to form a clamping part 13. The upper end of the upper mold 2 protrudes outward to form a second clamping part 21. The clamping part 13 can extend below the second clamping part 21 and abut against the bottom surface of the second clamping part 21. A driving device for driving the clamps 12 is also provided inside the upper slider. The upper mold 2 is located at the center below the upper slider 1, i.e., inside the upper slider 1. The drive device drives the clamp 12 to slide in the clamping groove 11. When the upper mold 2 needs to be installed on the bottom surface of the upper slider 1, the drive device drives the clamp 12 to move inward to the upper slider 1, so that the clamping part 13 in the clamp 12 extends below the second clamping part 21 located on the upper mold 2, thereby locking the relative position of the upper slider 1 and the upper mold 2 in the vertical direction. When it is necessary to remove the upper mold 2, it is only necessary to drive the drive device to move the clamp 12 outward to the upper slider 1, so that the clamping part 13 moves out from below the second clamping part 21. The clamping groove 11 is provided with at least two grooves located on opposite sides of the upper slider 1, so that the clamp 12 can clamp the upper mold 2 from both sides. On the one hand, the upper mold 2 is subjected to uniform force on both sides, ensuring the stability of the clamping. On the other hand, it prevents the upper mold 2 from being moved by the clamp 12 due to only one side being acted upon by the clamp 12, causing the upper mold 2 to shift position.

[0036] like Figure 2As shown, multiple clamping grooves 11 are provided along the length of one side of the upper slider 1, and the number of clamping grooves 11 on the other side of the upper slider 1 is the same as the number of clamping grooves 11 on the other side. Each clamping groove 11 is provided with a single clamp 12. This arrangement increases the number of clamps 12, thereby increasing the fixing position of the upper slider 1 on the upper mold 2 and improving the stability of the connection between the upper slider 1 and the upper mold 2.

[0037] Example 2

[0038] This embodiment is similar to Embodiment 1 above, except that the upper slider 1 has a through hole inside for gas to pass through. The through hole connects the first gas interface 3 to an external gas source, and the through hole is a first gas passage. Gas from the external gas source can enter the first gas interface 3 through the first gas passage.

[0039] Example 3

[0040] like Figure 7 As shown, a stamping press includes a lower die 8, a lower worktable 9, a press, and an upper slide block device as described in the above embodiment. The lower die 8 is mounted on the upper surface of the lower worktable 9, and the upper slide block device is mounted on the drive end of the press. The upper die 2 in the upper slide block device is vertically aligned with the lower die 8. The press provides pressure for stamping, the lower worktable 9 bears the stamping pressure, and the lower die 8 is mounted on the lower worktable 9. The upper slide block device is mounted on the drive end of the press, and the press can drive the upper slide block device to move vertically. The upper die 8 in the upper slide block device is vertically aligned with the lower die 8. During stamping, the raw material is first placed on the upper surface of the lower die 8, and then the press is started. The drive end of the press drives the upper slide device of the press to press down the lower die 8. Finally, the upper die and the lower die 8 of the upper slide device of the press press press respectively press the upper and lower surfaces of the material, and stamp the material into the preset shape. Then, the drive end of the press drives the upper slide device of the press to move upward, which drives the upper die to leave the stamped workpiece. Finally, the automatic conveying equipment takes out the workpiece and completes the stamping.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
