Description

Technical Field

[0001] The invention belongs to the field of automation equipment, and specifically discloses a fully automatic oil press production line with automatic loading and unloading. Background Art

[0002] A hydraulic press (a type of hydraulic press) is a type of mechanical stamping that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the cylinder / piston through the hydraulic pipeline by the force of the pump. Then there are several sets of seals that cooperate with each other in the cylinder / piston. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to make the cylinder / piston circulate and do work, thereby completing a certain mechanical action as a kind of productivity. It can be used in stamping, bending, shearing and stretching processes on metal sheets.

[0003] After searching, Chinese patent publication number CN111390002B proposes an integrated device for immersion and stamping of stainless steel plates, including a stamping mechanism and a stretching water spraying mechanism; the stamping mechanism is installed on the frame body, and one end of the stamping mechanism is connected to the bottom end of the intermittent rotating mechanism of the stainless steel plate through a sliding linkage mechanism, and the stretching water spraying mechanism is arranged on one side of the frame body, and one end of the intermittent rotating mechanism of the stainless steel plate can be rotated and inserted into the stretching water spraying mechanism. The stainless steel plate is clamped in the arc-shaped bayonet on the front side of the stainless steel plate clamping plate. In the process of the stamping mechanism returning upward after completing the stamping, it can drive the cross-shaped rotating plate to rotate 1 / 4 circle, so that the stainless steel plate of the next station is transferred to the stretching water spraying mechanism to soak in the stretching water, and the stainless steel plate in the stretching water spraying mechanism is transferred to the stamping mechanism, and the stainless steel plate can be stamped under the drive of the stamping cylinder.

[0004] Although the above-mentioned prior art realizes the rotation of 1 / 4 of a circle of the stainless steel plate, and rotates the stainless steel plate soaked in stretching water into the stamping mechanism for stamping, the prior art adopts the form of rotation to replace the plate, and the plate will be deformed after stamping. For example, when stamped into a bowl or a basin, its shape is concave downward by a certain distance. When the clamp rebounds, if the concave bottom fails to completely pop out of the mold, motion interference will occur during rotation. Therefore, the operator is required to manually disassemble the plate in the narrow space in the mold, which is troublesome and has low safety. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a fully automatic hydraulic press production line with automatic loading and unloading to solve the problem in the prior art that the stamped sheet cannot be completely ejected from the mold.

[0006] To achieve the above object, the present invention provides a fully automatic hydraulic press production line for automatic loading and unloading, including a bottom plate.

A second connecting plate is fixedly connected to one side of the outer wall of the pressing plate. A clamp is fixedly connected to the other side of the outer wall of the second connecting plate. A plate is clamped and fixed inside the clamp;

[0008] The height adaptation assembly is used to adjust the ejectable height of the plate.

[0009] In the above technical solution, preferably, the height adaptation assembly includes a screw rod inserted and screwed inside the sleeve. The middle part of the outer wall of the screw rod is fixedly connected with a third rotating part. A cross plate is fixedly connected to the outer wall of the third rotating part. Convex plates are fixedly connected to the four ends of the cross plate. The sliding seat is inserted and slidably connected to the outside of the upper and lower sides of the convex plate. A special-shaped plate extending downward is fixedly connected to the bottom of one side of the convex plate. The top end of the screw rod is fixedly connected with a first adjusting wheel. A fixed sleeve is sleeved and fixedly connected to the outer wall of the sleeve. Fourth connecting plates evenly distributed and arranged in a circumferential array are fixedly connected to the outer wall of the fixed sleeve. A vertical plate is fixedly connected to the top of one end of the fourth connecting plate. Two symmetrically arranged slide rails are fixedly connected to one side of the outer wall of the vertical plate. One end of the special-shaped plate is slidably connected to the outer wall of the slide rail.

[0010] In the above technical solution, preferably, the top of the outer wall of the cross plate is rotatably connected to a first rotating part set in a circular ring shape, the top of the outer wall of the first rotating part is fixedly connected to a first threaded sleeve, the top of the outer wall of the first threaded sleeve is fixedly connected to a second adjusting wheel, the outer wall of the first threaded sleeve is threaded with a fourth rotating part, the outer wall of the fourth rotating part is fixedly connected to four first connecting plates evenly distributed and in a circular array, the end of the first connecting plate is fixedly connected to a limiting plate, and the guide rod is inserted and slidably connected to the inside of the limiting plate.

[0011] In the above technical solution, preferably, the bottom of the cross plate is fixedly connected to a second rotating member, the outer wall of the second rotating member is screwed with a second threaded sleeve, the top of the outer wall of the second threaded sleeve is rotatably connected to a ring, the outer wall of the ring is fixedly connected to four evenly distributed and circularly arrayed third connecting plates, and the third connecting plates are connected to one side of the outer wall of the sliding seat.

[0012] In the above technical solution, preferably, an isolation cavity is provided inside the first threaded sleeve.

[0015] In the above technical solution, preferably, limit blocks are provided at both upper and lower ends of the sliding seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By setting a height adaptation component and turning the first adjustment wheel to make the cross plate drive the plate to move up and down, the upper and lower heights of the plate can be adjusted, and then a sufficient rebound height can be set according to the shape of the plate after stamping, to ensure that the bottom end of the plate can completely separate from the interior of the lower mold during the rebound after being stamped, thereby completely avoiding motion interference caused by the rotation process.

[0018] By setting up structures such as the first threaded sleeve and the limit plate, the upper and lower heights of the limit plate can be adjusted by turning the second adjusting wheel and the elastic force of the reset spring can be limited, so that the rebound height of the plate can be accurately controlled. After the upper mold moves up, it can be separated from its stamping surface at a certain distance, thereby completely preventing the movement interference caused by the plate still being in contact with the stamping surface of the upper mold under the push of the reset spring during rotation.

[0019] By setting up structures such as the second rotating member and the collar, rotating the second rotating member can adjust the vertical height of the sliding seat. Thus, when the elastic force of the return spring is too tight, the position of the sliding seat can be lowered to relax the shape of the return spring, thereby reducing its tightness and mechanical fatigue.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0031] As Figures 1-7 shown, a fully automatic hydraulic press production line for automatic loading and unloading includes a bottom plate 1. One side edge at the top of the bottom plate 1 is fixedly connected to a vertical frame 2. A driving cylinder 3 is fixedly installed at the top of the vertical frame 2. The output end of the driving cylinder 3 is fixedly connected to a driving rod 4. A lower end of the driving rod 4 is fixedly installed with an upper mold 5. The top of the bottom plate 1 is fixedly connected to a first support 6. The top of the first support 6 is fixedly connected to a lower mold 7, and the positions of the lower mold 7 and the upper mold 5 are vertically corresponding. The driving cylinder 3 drives the driving rod 4 to move downward, so that the upper mold 5 is pressed into the interior of the lower mold 7 to complete the stamping of the sheet 26.

[0032] A pair of industrial robots for loading and unloading are arranged outside the bottom plate 1. The industrial robots are prior art and are used to pick up or place the sheet 26. The top of the bottom plate 1 is also fixedly connected to a second support 9. The top of the second support 9 is fixedly connected to a base 10. A sleeve 11 is inserted and rotatably connected to the outer wall of the base 10. A ratchet transmission assembly 8 for driving the sleeve 11 to rotate is arranged between the sleeve 11 and the upper mold 5. The ratchet transmission assembly 8 is prior art and is composed of a ratchet, several bevel gears, several connecting rods, and a rack and pinion, which will not be elaborated here. A height adaptation assembly is arranged at the top of the base 10. Above the height adaptation assembly, there are four sliding seats 17 evenly distributed and arranged in a circumferential array. Two symmetrically arranged guide rods 19 are fixedly connected to the top of the sliding seat 17. The outer walls of adjacent two guide rods 19 are inserted and slidably connected to the same pressing plate 24. A return spring 18 is fixedly connected between the pressing plate 24 and the sliding seat 17. A second connecting plate 25 is fixedly connected to one side of the outer wall of the pressing plate 24. A fixture 27 is fixedly connected to the other side of the outer wall of the second connecting plate 25. The sheet 26 is clamped and fixed inside the fixture 27. When the sheet 26 is pressed by the upper mold 5 and then clamped into the interior of the lower mold 7, the pressure will be synchronously applied to the pressing plate 24 through the connection of the second connecting plate 25 and slide downward along the guide rods 19. When the upper mold 5 moves upward, the pressure applied to the pressing plate 24 gradually disappears. Under the pushing force of the elastic force of the return spring 18, the sheet 26 is ejected from the lower mold 7. The height adaptation assembly is used to adjust the ejectable height of the sheet 26.

[0033] The height - adapting component includes a screw rod 13 inserted and screwed inside a sleeve 11. The upper section of the outer wall of the screw rod 13 is set as a smooth shaft. A third rotating member 37 is fixedly connected to the middle of the outer wall of the screw rod 13. A cross - shaped plate 15 is fixedly connected to the outer wall of the third rotating member 37. It should be noted here that the third rotating member 37 is a prior art, such as a bearing, etc. Convex plates 16 are fixedly connected to the four ends of the cross - shaped plate 15. A sliding seat 17 is inserted and slidably connected to the outside of the upper and lower sides of the convex plate 16. Limit blocks are provided at both the upper and lower ends of the sliding seat 17, and the limit blocks can ensure that the sliding seat 17 will not break away from the inside of the convex plate 16 during sliding. A special - shaped plate 35 extending downward is fixedly connected to the bottom of one side of the convex plate 16. A first adjusting wheel 14 is fixedly connected to the top end of the screw rod 13. A fixed sleeve 12 is sleeved and fixedly connected to the outer wall of the sleeve 11. Fourth connecting plates 32 evenly distributed and arranged in a circular array are fixedly connected to the outer wall of the fixed sleeve 12. A vertical plate 33 is fixedly connected to the top of one end of the fourth connecting plate 32. Two symmetrically arranged slide rails 34 are fixedly connected to one side of the outer wall of the vertical plate 33. One end of the special - shaped plate 35 is slidably connected to the outer wall of the slide rail 34. The fixed sleeve 12 and the sleeve 11 are in a fixed state, so the slide rail 34 is also structurally fixed to the sleeve 11. Therefore, when the screw rod 13 is twisted by the first adjusting wheel 14, the connection between the slide rail 34 and the special - shaped plate 35 gives a restriction on the rotation of the cross - shaped plate 15. So the cross - shaped plate 15 will not be affected by the screw rod 13 and rotate. With the guidance of the cross - shaped plate 15, the lower section of the screw rod 13 can also gradually disengage from the inside of the sleeve 11 during rotation, thereby vertically raising the height of the cross - shaped plate 15, and correspondingly raising the height of the plate 26. Through this design, the specific height of the plate 26 can be freely adjusted to ensure that after stamping, there is sufficient space for the deformed plate 26 to completely pop out of the inside of the lower die 7.

[0034] The top of the outer wall of the cross plate 15 is rotatably connected to a first rotating member 22 in the shape of a ring. The bottom of the first rotating member 22 is fixedly connected to a slider 39 in the shape of a ring, and the slider 39 is inserted and rotatably connected to the outer wall of the cross plate 15. The top end of the outer wall of the first rotating member 22 is fixedly connected to a first threaded sleeve 23. The top of the outer wall of the first threaded sleeve 23 is fixedly connected to a second adjusting wheel 36. A fourth rotating member 38 is screwed onto the outer wall of the first threaded sleeve 23. Four first connecting plates 21 evenly distributed and arranged in a circumferential array are fixedly connected to the outer wall of the fourth rotating member 38. A limiting plate 20 is fixedly connected to the end of the first connecting plate 21, and the guide rod 19 is inserted and slidably connected inside the limiting plate 20. The guide rod 19 passes through and inserts into the upper and lower parts of the limiting plate 20, which restricts the rotation of the first threaded sleeve 23. Therefore, when the first threaded sleeve 23 is rotated along the surface of the cross plate 15 by twisting the second adjusting wheel 36, the first threaded sleeve 23 is correspondingly driven to move up and down. Through the connection of the first connecting plate 21, the limiting plate 20 is synchronously driven to move up and down along the guide rod 19. Since the limiting plate 20 is located above the pressing plate 24, the rebound position of the pressing plate 24 can be restricted, thereby facilitating the precise control of the rebound height of the plate 26.

[0035] The bottom of the cross plate 15 is fixedly connected to a second rotating member 29. A second threaded sleeve 28 is screwed onto the outer wall of the second rotating member 29. The top of the outer wall of the second threaded sleeve 28 is rotatably connected to a collar 30. Four third connecting plates 31 evenly distributed and arranged in a circumferential array are fixedly connected to the outer side wall of the collar 30, and the third connecting plates 31 are connected to one side of the outer wall of the sliding seat 17. By connecting the collar 30 and the sliding seat 17 through the third connecting plate 31, since the sliding seat 17 is restricted by the cross plate 15 and cannot rotate, when the second rotating member 29 is rotated to move up and down along the second threaded sleeve 28, the collar 30 can be synchronously driven to move up and down, thereby adjusting the up and down position of the sliding seat 17. Through this design, when the plate 26 is in a lower position, the position of the sliding seat 17 can be appropriately lowered to reduce the compression on the return spring 18, reduce its mechanical wear, and prevent it from rebounding quickly during overall high compression, thereby ensuring a smooth and round return process and preventing the plate 26 from suddenly bouncing against the bottom surface of the upper die 5 and causing secondary damage.

[0036] An isolation cavity 40 is provided inside the first threaded sleeve 23. Through this design, the contact between the screw 13 and the first threaded sleeve 23 can be reduced, thereby preventing interference in rotation between the two.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
