DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Embodiment 1

[0031] Reference Figure 1-3 A stamping forming ejection device comprises a stamping equipment body, the stamping equipment body comprises a hydraulic cylinder 1 and a base 2, the output end of the hydraulic cylinder 1 is connected to a stamping upper die set 3, the base 2 is provided with a stamping lower die set 4 which cooperates with the stamping upper die set 3 to punch a workpiece, the stamping upper die set 3 is provided with a plurality of stamping blocks 5 on the side opposite to the stamping lower die set 4, the stamping lower die set 4 is provided with a stamping groove 6 which matches the stamping block 5, the interior of the base 2 is provided with an ejection assembly for ejecting the workpiece and an adjustment assembly for adjusting the position of the ejection assembly, the interior of the base 2 is provided with an installation groove 7 which is convenient for installing the ejection assembly and the adjustment assembly, and one side of the installation groove 7 is provided with an observation window 8 which is convenient for an operator to observe.

[0032] Reference Figure 2The ejection assembly includes a plurality of sleeves 9 fixed in the mounting groove 7, a compression spring 10 is provided inside the sleeve 9, one end of the compression spring 10 is fixedly connected to the bottom wall of the sleeve 9, and the other end of the compression spring 10 is abutted with a circular stop block 11, and the top end of the circular stop block 11 passes through the sleeve 9 and is connected with a workpiece ejection rod 12 for ejecting the workpiece. Specifically, in the utility model, through the design of the ejection assembly, the workpieces retained in the stamping lower die set 4 after stamping are ejected uniformly, avoiding the safety hazards when manually picking up the workpiece, and improving the safety of the device; on the other hand, through the design of the ejection assembly, the problem of low efficiency of manual picking up of workpieces during mass production and processing is solved, and the practicality of the device is improved.

[0033] When the workpiece in the stamping lower die set 4 is stamped, the hydraulic cylinder 1 is started to drive the stamping upper die set 3 to stamp the stamping lower die set 4. At this time, the workpiece in the stamping lower die set 4 is driven by the stamping action of the stamping upper die set 3, and the workpiece ejector rod 12 moves downward, thereby squeezing the compression spring 10 abutting against the circular stop block 11 to cause it to deform. After the workpiece is stamped, the compression spring 10 is reset and drives the circular stop block 11 to move upward, so that the workpiece ejector rod 12 ejects the workpiece in the stamping lower die set 4.

[0034] Reference Figure 2-3 The adjusting assembly is fixed at the bottom end of the ejection assembly, and the adjusting assembly includes a first adjusting screw 13 arranged in the mounting groove 7, one end of the first adjusting screw 13 is rotatably connected to the inner wall of the mounting groove 7, and the other end of the first adjusting screw 13 passes through the base 2 and is connected to a first rotating handle 14 for adjusting the first adjusting screw 13, and a plurality of U-shaped moving blocks 15 are threadedly connected to the first adjusting screw 13, and a plurality of limiting slide bars 16 for guiding are slidably connected to both sides of the U-shaped moving block 15, and the two ends of the limiting slide bar 16 are respectively fixedly connected to the inner wall of the mounting groove 7. Specifically, in the utility model, the position of the U-shaped moving block 15 is adjusted through the design of the first adjusting screw 13 and the first rotating handle 14, so that the ejection assembly provided at the top of the U-shaped moving block 15 is laterally moved, thereby improving the applicable scope of the ejection assembly; through the design of the limiting slide bar 16, the position of the U-shaped moving block 15 is limited to prevent it from rotating when the first adjusting screw 13 rotates, thereby improving the stability of the device during use.

[0035] When adjusting the lateral position of the ejector assembly, the operator rotates the first rotating handle 14 to drive the first adjusting screw 13 to rotate, so that the multiple U-shaped moving blocks 15 threadedly connected on both sides of the first adjusting screw 13 produce relative lateral movement, thereby adjusting the lateral position of the ejector assembly provided on the top of the U-shaped moving block 15.

[0036] Reference Figure 2-3 The adjustment assembly also includes a second adjusting screw 17 arranged at the top of the U-shaped moving block 15, one end of the second adjusting screw 17 is rotatably connected to the inner wall of the U-shaped moving block 15, wherein one end of the second adjusting screw 17 on the U-shaped moving block 15 located in the middle of the mounting groove 7 passes through the base 2 and is connected to a second rotating handle 18 for easy adjustment, and the other ends of the second adjusting screws 17 located on both sides of the mounting groove 7 pass through the U-shaped moving block 15 and are rotatably connected to a moving block 19, and a sliding groove 20 matching the moving block 19 is provided inside the mounting groove 7, and a plurality of moving blocks 21 21 are threadedly connected to the second adjusting screw 17, and a guide block 22 is provided at the bottom end of the moving block 21, and a guide groove 23 matching the guide block 22 is provided on the U-shaped moving block 15. Specifically, in the utility model, the position of the second moving block 21 on the U-shaped moving block 15 is adjusted through the design of the second adjusting screw 17 and the second rotating handle 18, so that the ejection assembly fixed at the top of the second moving block 21 produces longitudinal movement, further improving the application range of the ejection assembly; through the design of the moving block 19 and the slide groove 20, when the operator rotates the first adjusting screw 13 to adjust the lateral position of the U-shaped moving block 15, the second adjusting screw 17 can follow the movement of the U-shaped moving block 15 and produce corresponding lateral movement in the mounting groove 7, thereby ensuring the normal operation of the adjustment assembly; through the design of the guide block 22 and the guide groove 23, the position of the second moving block 21 is restricted to prevent it from rotating when the second adjusting screw 17 rotates, thereby further improving the stability of the device during use.

[0037] It should be noted that, in the present invention, the threads on the first adjusting screw 13 and the second adjusting screw 17 are both designed with positive and negative threads with opposite rotation directions at both ends, so that when the operator rotates the first adjusting screw 13 and the second adjusting screw 17 to adjust the position of the U-shaped moving block 15 and the moving block 21, the U-shaped moving block 15 and the moving block 21 can produce relative lateral or longitudinal movement, effectively improving the adjustment efficiency of the adjustment component; on the other hand, the positions of the U-shaped moving block 15 and the moving block 21 located in the middle of the first adjusting screw 13 and the second adjusting screw 17 are relatively fixed, thereby avoiding unnecessary movement when adjusting the component, further improving the adjustment efficiency of the adjustment component, and reducing the restrictiveness of the device during use.

[0038] When adjusting the longitudinal position of the ejector assembly, the operator rotates the second rotating handle 18 to drive the second adjusting screw 17 to rotate, so that the multiple moving blocks 21 threadedly connected on both sides of the second adjusting screw 17 produce relative longitudinal movement, thereby adjusting the longitudinal position of the ejector assembly fixed on the top of the moving block 21.

[0039] Reference Figure 3 A plurality of driving pulleys 24 are provided on the second adjusting screw 17 located in the middle of the mounting groove 7, and a plurality of driven pulleys 25 matching the driving pulleys 24 are provided on the second adjusting screws 17 located on both sides of the mounting groove 7. A synchronous belt 26 for transmission is sleeved on the driving pulley 24 and the driven pulley 25. Specifically, in the utility model, the plurality of second adjusting screws 17 are uniformly controlled through the design of the driving pulley 24, the driven pulley 25 and the synchronous belt 26, so that when the operator adjusts the longitudinal position of the ejection assembly, he only needs to rotate the second rotating handle 18 to adjust the position of the plurality of moving blocks 21 on the plurality of U-shaped moving blocks 15, thereby improving the practical performance of the device.

[0040] Embodiment 2

[0041] This embodiment is further optimized on the basis of the first embodiment. During the use of the stamping device, we found that when the operator adjusts the lateral position of the ejection assembly, the synchronous belt 26 sleeved on one end of the second adjusting screw 17 will be loosened or tightened accordingly during the process of adjusting the position of the ejection assembly. When the synchronous belt 26 is in a loose state, the operator can only adjust the position of the moving block 21 on the second adjusting screw 17 fixedly connected to the second rotating handle 18 by turning the second rotating handle 18, which affects the adjustment of the longitudinal position of the ejection assembly. When the synchronous belt 26 is in a taut state, when the operator turns the first rotating handle 14 to adjust the lateral position of the ejection assembly, the U-shaped moving block 15 threadedly connected to the first adjusting screw 13 is difficult to expand outward under the taut state of the synchronous belt 26. At this time, if the second rotating handle 18 is forcibly rotated, the synchronous belt 26 is very likely to be torn under the outward expansion of the U-shaped moving block 15, affecting the normal use of the device.

[0042] Reference Figure 4 An auxiliary adjusting component for adjusting the auxiliary adjusting component is provided on one side of the mounting groove 7 close to the driving pulley 24. The auxiliary adjusting component includes a mounting block 27 fixedly arranged on one side of the mounting groove 7. An adjusting slider 28 is slidably connected inside the mounting block 27. A compression spring 29 is fixedly connected to the bottom end of the adjusting slider 28. The other end of the compression spring 29 is fixedly connected to the inner wall of the mounting block 27. An adjusting pulley 30 for adjusting the tightness of the synchronous belt 26 is provided on the adjusting slider 28. Specifically, in the utility model, the tightness of the synchronous belt 26 is adjusted during the adjustment process of the adjusting component through the design of the auxiliary adjusting component, so that it is always in close contact with the outer surfaces of the driving pulley 24 and the driven pulley 25, thereby ensuring the normal operation of the device.

[0043] During the operation of the adjustment assembly, the adjustment slider 28 drives the adjustment pulley 30 to move accordingly under the action of the compression spring 29, so that the synchronous belt 26 is always in close contact with the outer surfaces of the driving pulley 24 and the driven pulley 25, ensuring the normal operation of the device.

[0044] Embodiment 3

[0045] This embodiment is further optimized on the basis of the second embodiment. During the use of the stamping device, we found that when the stamping lower die set 4 needs to be replaced, the workpiece ejector rod 12 placed inside the stamping lower die set 4 is always inserted in the stamping lower die set 4 under the action of the compression spring 10, which makes the replacement of the stamping lower die set 4 inconvenient and the practical performance of the device poor.

[0046] Reference Figure 5-6 , the base 2 is provided with a pressing assembly for pressing down the ejection assembly, and the pressing assembly includes a guide connecting plate 31 fixedly arranged on both sides of the circular stop block 11, and the sleeve 9 is provided with a movable guide groove 1 32 matching the guide connecting plate 31, and a pressing plate 33 is fixedly arranged on the guide connecting plate 31 located in the middle of the mounting groove 7, and movable guide grooves 2 34 matching the pressing plate 33 are provided on both sides of the mounting groove 7, and an electric cylinder 35 for applying pressure to the pressing plate 33 is symmetrically arranged on the base 2, and the output end of the electric cylinder 35 conflicts with the top end of the pressing plate 33. Specifically, in the utility model, the ejection state of the workpiece ejection rod 12 is controlled by the design of the pressing assembly, so that when the stamping lower die set 4 needs to be replaced, it can be pressed by the output end of the electric cylinder 35 to shrink into the mounting groove 7 and separate from the stamping lower die set 4, thereby improving the practical performance of the device;

[0047] It should be noted that, in this embodiment, the guide connecting plate 31 located in the middle of the mounting groove 7 has heights of the guide connecting plates 31 on both sides decreasing one by one. Through this design, the states of multiple workpiece ejector rods 12 can be synchronously controlled, thereby improving the practical performance of the device.

[0048] When the stamping lower die set 4 needs to be replaced, the electric cylinder 35 is started to drive the pressure plate 33 fixedly connected to the output end of the electric cylinder 35 to be pressed down, so that the guide connecting plate 31 fixedly connected to the pressure plate 33 drives the guide connecting plates 31 abutting on both sides thereof to move downward, so that the workpiece ejection rod 12 is retracted inward and disengaged from the stamping lower die set 4, thereby improving the operator's convenience in replacing the stamping lower die set 4.

[0049] The use process of a punching and ejecting device provided by the utility model is as follows:

[0050] When the workpiece in the stamping lower die set 4 is stamped, the hydraulic cylinder 1 is started to drive the stamping upper die set 3 to stamp the stamping lower die set 4. At this time, the workpiece in the stamping lower die set 4 is driven by the stamping action of the stamping upper die set 3 to move the workpiece ejector rod 12 downward, thereby squeezing the compression spring 10 abutting against the circular stop block 11 to cause it to deform. After the workpiece is stamped, the compression spring 10 is reset and drives the circular stop block 11 to move upward, so that the workpiece ejector rod 12 ejects the workpiece in the stamping lower die set 4.

[0051] When adjusting the lateral position of the ejector assembly, the operator rotates the first rotating handle 14 to drive the first adjusting screw 13 to rotate, so that the multiple U-shaped moving blocks 15 threadedly connected on both sides of the first adjusting screw 13 produce relative lateral movement, thereby adjusting the lateral position of the ejector assembly provided on the top of the U-shaped moving block 15;

[0052] When adjusting the longitudinal position of the ejector assembly, the operator rotates the second rotating handle 18 to drive the second adjusting screw 17 to rotate, so that the plurality of second moving blocks 21 threadedly connected on both sides of the second adjusting screw 17 produce relative longitudinal movement, thereby adjusting the longitudinal position of the ejector assembly fixed at the top of the second moving block 21;

[0053] During the operation of the adjustment assembly, the adjustment slider 28 drives the adjustment pulley 30 to move accordingly under the action of the compression spring 29, so that the synchronous belt 26 is always in close contact with the outer surfaces of the driving pulley 24 and the driven pulley 25, ensuring the normal operation of the device;

[0054] When the stamping lower die set 4 needs to be replaced, the electric cylinder 35 is started to drive the pressure plate 33 fixedly connected to the output end of the electric cylinder 35 to be pressed down, so that the guide connecting plate 31 fixedly connected to the pressure plate 33 drives the guide connecting plates 31 abutting on both sides thereof to move downward, so that the workpiece ejection rod 12 is retracted inward and disengaged from the stamping lower die set 4, thereby improving the operator's convenience in replacing the stamping lower die set 4.
