Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and specifically to a stainless steel plate stamping equipment for processing gas meter boxes. Background Art

[0002] In the field of processing gas meter boxes, the stamping process of stainless steel plates is a key link. Many problems have emerged in the actual application of traditional stainless steel plate stamping equipment. For example, there is no effective centering adjustment mechanism for loading materials of different widths, which leads to position deviation of the materials during stamping, easily resulting in insufficient stamping accuracy and an increase in the defective rate of products. Moreover, during the demoulding process, previous equipment often relied on manual assistance for demoulding, with low efficiency and easy damage to the finished products due to improper operation. At the same time, the traditional equipment's blanking method is mostly fixed-position material receiving, which cannot adapt to the movement of the upper die during the stamping process, resulting in inaccurate material receiving, affecting production continuity, and making it difficult to meet the requirements of the gas meter box processing industry for high-efficiency and high-precision production. Summary of the Invention

A bearing plate is fixedly installed between the pair of first support rods and the pair of second support rods. A pair of slide rails are fixedly installed on the bearing plate. A pair of guide blocks are respectively slidably installed on the slide rails. Side plates are respectively fixedly installed on the pair of guide blocks.

[0011] Preferably, a through hole is formed in the baffle, and the driving roller and the pressing roller respectively penetrate through the through hole.

[0012] Beneficial effects:

[0013] 1. Through the centering feeding component, the distance between the fixing plates can be flexibly adjusted to adapt to materials of any width. The driving motor drives the driving roller to rotate. With the cooperation of the pressing roller and the third spring, the material can be automatically and tightly pressed on the driving roller for feeding, ensuring that the material is accurately transported between the upper die and the lower die, greatly improving the accuracy and efficiency of feeding, and providing a good foundation for the subsequent stamping process.

[0014] 2. Through the demoulding component, when the stamping of the material is completed, the finished product stays in the die groove of the upper die. When the upper die moves to the uppermost position, the top plate contacts the contact plate, pushing the discharging rod downward. With the cooperation of the first spring, the lower end of the discharging rod can quickly eject the material in the die groove, realizing automatic demoulding, reducing manual intervention, and improving the demoulding efficiency and product quality.

[0015] 3. Through the follow-up feeding component, the feeding process is controlled by the up-and-down movement of the upper die. When the upper die rises, through the linkage of components such as the L-shaped rod and the push rod, the side plate is driven to move along the slide rail, so that the electric roller moves between the upper die and the lower die to receive the material; when the upper die descends, it can automatically drive the electric roller away, and the material is discharged by means of the blocking plate and the rotation of the electric roller. The whole process is closely coordinated with the stamping process, ensuring the accuracy of feeding and the continuity of production, and significantly improving the production efficiency.

[0016] In summary, through the centering feeding component of the present invention, materials of any width can be actively fed, eliminating the manual feeding process and reducing the danger of manual feeding. Through the demoulding component, the material can be demoulded from the upper die, realizing automatic demoulding of the finished product. Through the follow-up feeding component, the material can be continuously fed along with the movement of the upper die, eliminating the manual handling of feeding, shortening the overall time of the stamping process, and reducing the risk coefficient of manual material taking.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-9 , the present invention provides a technical solution: a stainless steel plate stamping device for processing a gas meter box, including a base 1, four support columns 2 with the same structure are fixedly installed on the base 1, a top plate 3 is fixedly installed between the upper ends of the support columns 2, a bearing frame 4 is fixedly installed on the top plate 3, a stamping motor 5 is fixedly installed on the inner rear wall surface of the bearing frame 4, a first shaft rod 6 is fixedly installed on the driving end of the stamping motor 5, a second shaft rod 7 is rotatably installed on the inner front wall surface of the bearing frame 4, turntables 8 are respectively fixedly installed on the first shaft rod 6 and the second shaft rod 7, a connecting rod 9 is fixedly installed between the turntables 8, a stamping rod 10 is rotatably installed on the connecting rod 9, an opening 11 is formed on the top plate 3, the lower end of the stamping rod 10 penetrates through the opening 11, an upper die 12 is slidably installed between the support columns 2, the lower end of the stamping rod 10 is hingedly connected to the upper wall surface of the upper die 12, a demolding assembly is provided on the upper die 12, a lower die 13 is fixedly installed on the base 1 and located between the four support columns 2, a follow-up blanking assembly is provided on the base 1, and a centering feeding assembly is provided between the rear wall surface of the base 1 and the rear wall surface of the bearing frame 4.

[0021] The centering feeding assembly is used to center and adjust the feeding of the material, so that materials of any width can be transported between the upper die 12 and the lower die 13. By starting the stamping motor 5, the driving end of the stamping motor 5 drives the first shaft rod 6 to rotate. The first shaft rod 6 drives the turntable 8 to rotate. The turntables 8 are connected by the connecting rod 9, so that the connecting rod 9 drives the two turntables 8 to rotate simultaneously. The second shaft rod 7 plays an auxiliary role in driving the turntable 8 to rotate. At this time, the connecting rod 9 drives the stamping rod 10 to move. Since the connecting rod 9 is fixedly installed at the eccentric position between the turntables 8, the connecting rod 9 rotates around the center of the turntable 8. At this time, the connecting rod 9 drives the stamping rod 10 to perform a crank - connecting rod motion, so that the stamping rod 10 drives the upper die 12 to move up and down reciprocally, and then the material is stamped. After the material stamping is completed, the finished product stays in the upper die 12. The demolding assembly is used to demold the material. Since the upper die 12 will move upward during the demolding process, the follow-up blanking assembly will complete the material receiving process as the upper die 12 moves. When the upper die 12 descends, the follow-up blanking assembly resets to prepare for the next material receiving.

[0022] In this embodiment, it is further set that the demolding assembly includes a mold groove 14, a discharge rod 15, a contact plate 16, a first spring 17, a ejector rod 18, a material receiving frame 19 and a second spring 20; the mold groove 14 is opened on the lower wall surface of the upper die 12, four through holes are opened in the mold groove 14, the discharge rod 15 is inserted into the four through holes, the upper end of the discharge rod 15 penetrates through the through hole and is fixedly installed with the contact plate 16, a first spring 17 is fixedly installed between the contact plate 16 and the outer upper wall surface of the upper die 12, and the first spring 17 is sleeved on the discharge rod 15.

[0023] After the material is stamped, the finished material stays in the mold groove 14. When the upper mold 12 moves to the uppermost position, at this time, the contact plate 16 contacts the top plate 3, and the contact plate 16 is pushed downward to drive the discharge rod 15. At this time, the first spring 17 is compressed under force, and the lower end of the discharge rod 15 pushes out the material in the mold groove 14, thus completing the demolding of the finished material.

[0024] In this embodiment, it is further set that grooves are respectively formed on one side of the four corners of the base 1 and below the lower mold 13. The ejector rods 18 are inserted into the grooves. A receiving frame 19 is fixedly installed between the upper ends of the ejector rods 18. The lower mold 13 is located within the receiving frame 19. A second spring 20 is fixedly installed between the lower wall surface of the receiving frame 19 and the base 1. The second spring 20 is sleeved on the ejector rod 18.

[0025] When the material is placed between the upper mold 12 and the lower mold 13, at this time, the receiving frame 19 and the lower mold 13 carry the material. When the upper mold 12 descends, first the upper mold 12 contacts the material, and the upper mold 12 continues to descend, causing the upper mold 12 to push the receiving frame 19, and then the lower mold 13 passes through the receiving frame 19. At this time, the second spring 20 is compressed under force. The upper mold 12 and the lower mold 13 perform stamping and shearing on the material through the shearing force. When the upper mold 12 moves upward, at this time, the second spring 20 releases its elastic force, and then the receiving frame 19 is reset to lift the excess material.

[0026] In this embodiment, it is further set that the follow-up feeding assembly includes a pair of first support rods 21, a pair of second support rods 22, a bearing plate 23, a slide rail 24, a pair of guide blocks 25, a side plate 26, a blocking plate 27, an electric roller 28, an L-shaped rod 29, and a push rod 30; the height of the first support rod 21 is less than the height of the second support rod 22. A pair of first support rods 21 and a pair of second support rods 22 are fixedly installed on the base 1 from left to right in sequence and are located on one side of the support column 2. A bearing plate 23 is fixedly installed between the pair of first support rods 21 and the pair of second support rods 22. A pair of slide rails 24 are fixedly installed on the bearing plate 23. A pair of guide blocks 25 are respectively slidably installed on the slide rails 24. A side plate 26 is fixedly installed on each of the pair of guide blocks 25. A blocking plate 27 is fixedly installed between one sides of the side plates 26. A number of electric rollers 28 are installed between the side plates 26 and on one side of the blocking plate 27. The side wall surface of the upper mold 12 is hingedly connected with an L-shaped rod 29. One end of the L-shaped rod 29 is hingedly connected to the side wall surface of the upper mold 12. The corner of the L-shaped rod 29 is hingedly connected to the second support rod 22. The other end of the L-shaped rod 29 is hingedly connected with a push rod 30. The push rod 30 is hingedly connected to the side plate 26.

[0027] When the upper die 12 rises to the highest point, the electric roller 28 is started. The upper die 12 pulls the horizontal end of the L-shaped rod 29 upward, so that the horizontal end of the L-shaped rod 29 rotates around the corner end of the L-shaped rod 29, and then the vertical end of the L-shaped rod 29 rotates and pushes the push rod 30. The push rod 30 exerts a thrust on the side plate 26. Under the action of the guide block 25, the side plate 26 moves upward along the path of the slide rail 24 below the upper die 12, so that the electric roller 28 moves between the upper die 12 and the lower die 13. A plurality of electric rollers 28 receive the material. When the upper die 12 descends, the upper die 12 pushes the horizontal end of the L-shaped rod 29 downward, so that the horizontal end of the L-shaped rod 29 rotates around the corner end of the L-shaped rod 29, and then the vertical end of the L-shaped rod 29 rotates and pulls the push rod 30. The push rod 30 exerts a pulling force on the side plate 26. Under the action of the guide block 25, the side plate 26 moves away from the upper die 12 along the path of the slide rail 24. During this process, due to inertia, the finished product material contacts the baffle 27. When the electric roller 28 moves away from the upper die 12, the baffle 27 exerts a thrust on the finished product material, and under the rotation action of the electric roller 28, the material is discharged.

[0028] In this embodiment, it is further set that the length of the hinge connection end of the L-shaped rod 29 and the upper die 12 is greater than the length of the hinge connection end of the L-shaped rod 29 and the push rod 30.

[0029] In this embodiment, it is further set that the central feeding assembly includes a pair of fixing plates 31, a driving roller 32, a driving motor 33, a chute 34, a slider 35, a third spring 36 and a pressing roller 37; a pair of fixing plates 31 are fixedly installed between the base 1 and the rear wall surface of the bearing frame 4. A driving roller 32 is rotatably installed between the pair of fixing plates 31. A driving motor 33 is fixedly installed on the side wall surface of one of the fixing plates 31. The driving motor 33 is connected to the driving roller 32. A chute 34 is opened on the inner wall surface of the fixing plate 31 and above the driving roller 32. A slider 35 is slidably installed in the chute 34. A third spring 36 is fixedly installed between the slider 35 and the upper wall surface of the chute 34. A pressing roller 37 is rotatably installed between the sliders 35. An adjusting part is provided between the pair of fixing plates 31.

[0030] First, adjust the adjusting part so that the material can pass through the adjusting part. Start the driving motor 33. The driving motor 33 drives the driving roller 32 to rotate. Place the material between the driving roller 32 and the pressing roller 37. At this time, due to the thickness of the material, the material pushes the pressing roller 37 to move along the path of the chute 34 under the action of the slider 35, and squeezes the third spring 36. Then the third spring 36 releases elastic force to push the slider 35, so that the slider 35 pushes the pressing roller 37. The pressing roller 37 presses the material tightly on the driving roller 32, so that the driving roller 32 feeds the material.

[0031] In this embodiment, it is further arranged that the adjusting part includes a cross beam 38, a dovetail groove 39, a pair of moving blocks 40, dovetail blocks 41, threaded columns 42, baffles 43 and through holes 44; the cross beam 38 is fixedly installed between a pair of fixing plates 31 and is located above the sliding groove 34. A dovetail groove 39 is formed in the cross beam 38. A pair of moving blocks 40 are slidably installed on the cross beam 38. Threaded holes are formed in the moving blocks 40. Dovetail blocks 41 are slidably installed in the dovetail groove 39. Threaded columns 42 are screwed into the threaded holes. The threaded columns 42 are rotatably connected to the dovetail blocks 41. Baffles 43 are fixedly installed at the lower ends of the moving blocks 40. Through holes 44 are formed in the baffles 43. The driving roller 32 and the pressing roller 37 respectively pass through the through holes 44.

[0032] Push a pair of moving blocks 40 to adjust the distance between the moving blocks 40, so that the distance between the fixing plates 31 can be adjusted, and the distance between the fixing plates 31 can pass through the material. At this time, rotate the threaded column 42 so that the threaded column 42 feeds along the path of the threaded hole. The threaded column 42 pushes the dovetail block 41 until the dovetail block 41 contacts the lower wall surface of the dovetail groove 39, thereby limiting and fixing the moving block 40 to prevent the fixing plate 31 from moving.

[0033] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0034] During use, push a pair of moving blocks 40 to adjust the distance between the moving blocks 40, so that the distance between the fixed plates 31 is adjusted. The distance between the fixed plates 31 can pass through the material. At this time, rotate the threaded column 42 so that the threaded column 42 feeds along the path of the threaded hole. The threaded column 42 pushes the dovetail block 41 until the dovetail block 41 contacts the lower wall surface of the dovetail groove 39, and then limits and fixes the moving block 40 to prevent the fixed plate 31 from moving, so that the material can pass through the adjusting part. Start the driving motor 33, and the driving motor 33 drives the driving roller 32 to rotate. Place the material between the driving roller 32 and the pressing roller 37. At this time, because the material has a thickness, the material pushes the pressing roller 37 to move along the path of the sliding groove 34 under the action of the sliding block 35, and squeezes the third spring 36. Then, the third spring 36 releases elastic force to push the sliding block 35, so that the sliding block 35 pushes the pressing roller 37, and the pressing roller 37 presses the material tightly on the driving roller 32, so that the driving roller 32 feeds the material. By starting the stamping motor 5, the driving end of the stamping motor 5 drives the first shaft rod 6 to rotate, the first shaft rod 6 drives the turntable 8 to rotate, and the turntables 8 are connected by a connecting rod 9. Then, the connecting rod 9 drives the two turntables 8 to rotate simultaneously. The second shaft rod 7 plays an auxiliary role in the rotation of the turntable 8. At this time, the connecting rod 9 drives the stamping rod 10 to move. Since the connecting rod 9 is fixedly installed at the eccentric position between the turntables 8, the connecting rod 9 revolves around the center of the turntable 8. At this time, the connecting rod 9 drives the stamping rod 10 to perform a crank connecting rod 9 motion, so that the stamping rod 10 drives the upper die 12 to move up and down reciprocally, and then stamping processing is carried out on the material. After the material is stamped, the finished product stays in the upper die 12. After the material is stamped, the finished product stays in the die groove 14. When the upper die 12 moves to the uppermost position, at this time, the contact plate 16 contacts the top plate 3, and the contact plate 16 moves downward to push the discharging rod 15. At this time, the first spring 17 is compressed by force, and the lower end of the discharging rod 15 pushes the material in the die groove 14 out, thus completing the demolding of the finished product; During the process of the upper die 12 rising to the highest point, the electric roller 28 is started. The upper die 12 pulls the horizontal end of the L-shaped rod 29 upward, so that the horizontal end of the L-shaped rod 29 rotates around the corner end of the L-shaped rod 29. As a result, the vertical end of the L-shaped rod 29 rotates and pushes the push rod 30. The push rod 30 exerts a thrust on the side plate 26. Under the action of the guide block 25, the side plate 26 moves upward along the path of the slide rail 24 to the lower part of the upper die 12, so that the electric roller 28 moves between the upper die 12 and the lower die 13. A number of electric rollers 28 receive the material. When the upper die 12 descends, the upper die 12 pushes the horizontal end of the L-shaped rod 29 downward, so that the horizontal end of the L-shaped rod 29 rotates around the corner end of the L-shaped rod 29. As a result, the vertical end of the L-shaped rod 29 rotates and pulls the push rod 30. The push rod 30 exerts a pulling force on the side plate 26. Under the action of the guide block 25, the side plate 26 moves away from the upper die 12 along the path of the slide rail 24. During this process, due to inertia, the finished product material contacts the baffle plate 27. During the process of the electric roller 28 moving away from the upper die 12, the baffle plate 27 exerts a thrust on the finished product material, and under the rotational action of the electric roller 28, the material is discharged.
