Description

Technical Field

[0001] The invention belongs to the technical field of forging and punching, and in particular relates to an adjustable forging and punching device. Background Art

[0002] The process of forging a through hole or a non-through hole on the blank is called punching. This process usually occurs after the blank has just been heated. For some soft metals with strong ductility, forging and punching are sometimes used for processing. Punching is often the first step in the forging process of annular parts, followed by steps such as hole expansion. Since the extrusion pressure and friction between the workpiece and the punch are very large, it is very easy to cause rapid wear of the punch.

[0003] The patent application with application publication number CN117680545A discloses an adjustable forging punching device, which reduces the friction between the punch and the workpiece by lubrication, thereby reducing the wear of the punch. The patent realizes the recycling of lubricating oil through the design of the lubricating oil circuit, and can control the injection rate according to the magnitude of the friction force. However, this solution still has some problems;

[0004] For example, this solution uses a magnetic ring as a control element. The magnetic ring is easily demagnetized due to high temperature near a high-temperature blank, resulting in induction failure. Therefore, this solution has requirements for the temperature of the workpiece and the performance of the magnetic ring.

[0005] In addition, there are some problems with the existing forging and punching devices:

[0006] A: The amount and timing of oil supply need to be controlled relatively accurately. Insufficient oil supply will cause insufficient lubrication. When too much oil is supplied, a large amount of oil will take away more heat, causing the workpiece to cool down too quickly.

[0007] B: And during the forging process, the total amount of lubricating oil required is actually related to the depth of the punch penetrating into the workpiece, and has no strict relationship with the speed. In other words, the demand for lubricating oil is mainly related to the extrusion stroke between the punch and the workpiece, and when the punch stops penetrating, lubricating oil is actually not needed.

[0008] C: Although some oil supply mechanisms can control the oil supply according to the pressure, since this method is a continuous oil supply, if the movement speed is slow, the total oil supply will actually increase. Summary of the invention

[0009] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes an adjustable forging and punching device that automatically controls the lubricating oil supply at an appropriate time according to the intrusion stroke; in order to solve the influence of the forging speed on the oil supply, the present invention creatively proposes a quantitative oil supply mechanism. This scheme adopts the main idea of ​​sandwich oil supply, and realizes the technical effect of single quantitative oil supply by controlling the penetration sequence of the three chambers. The oil supply amount of this method is not affected by variables such as forging speed (during forging, the pressure is generally controlled, and the actual movement speed of the punch is not very controllable due to the influence of the hardness of the forging workpiece), so the stability and controllability are higher; not only that, the present invention utilizes the action of the forging punch intruding into the forging workpiece to drive the linkage springboard to bounce back and forth during the rising process, and drives the oil supply of the quantitative oil supply mechanism through the jumping of the linkage springboard, and automatically cancels the jumping of the linkage springboard in the reset stage, thereby achieving more accurate control of the oil supply.

[0010] The technical solution adopted by the present invention is as follows: The present invention proposes an adjustable forging and punching device, including a forging mechanism, a quantitative oil supply mechanism, a lifting control mechanism and a transverse one-way unlocking mechanism, the forging mechanism includes a forging base, a forging workpiece, a forging arm, a square pressure block and an extrusion type oil supply assembly, the forging workpiece is placed on the forging base, the forging workpiece is fixed to the forging base by a clamp, the forging arm is arranged on one side of the forging base, the square pressure block is arranged at the end of the forging arm, the lifting and lowering of the square pressure block can be controlled by the internal structure of the forging arm, and the extrusion type oil supply assembly is arranged on the square pressure block.

[0011] The lifting and lowering of the square pressure block can bring the extrusion type oil supply assembly to move up and down. When the extrusion type oil supply assembly descends, it can extrude and punch the forged workpiece on the one hand, and on the other hand, it can control the opening and closing of the lubrication oil circuit through the interaction between the forged workpiece and the extrusion type oil supply assembly.

[0012] Furthermore, the extrusion type oil supply assembly includes a forging punch, a control valve disc, a closing spring and a sealing ring. The forging punch is fixedly connected to the bottom of the square pressure block. A hollow cavity is provided on the forging punch. The control valve disc is snap-fitted and slidably arranged at the bottom of the hollow cavity. The outer side of the control valve disc is evenly distributed in an annular shape with side grooves. The closing spring is arranged between the step wall of the hollow cavity and the control valve disc, and the sealing ring is fixed to the control valve disc.

[0013] Through the interaction between the forging workpiece and the quantitative oil supply mechanism, the timing of lubricating oil supply can also be controlled. This supply timing and supply amount are only related to the depth of the forging punch penetrating into the forging workpiece, and the supply amount of this oil supply method is independent of factors such as the forging speed. It can solve the problem of difficult control of lubricating oil supply under different forging requirements, and overcome the technical contradiction that the lubricating oil cannot be too much (prone to excessive dirt, excessive cooling and other problems) nor too little (prone to insufficient lubrication, increased wear and other problems).

[0014] Furthermore, the quantitative oil supply mechanism includes a sequential quantitative oil supply component, an oil supply control component and an oil supply quantity adjustment component, the sequential quantitative oil supply component is arranged on the linkage control component, the oil supply control component is slidably arranged in the sequential quantitative oil supply component, and the oil supply quantity adjustment component is arranged in the sequential quantitative oil supply component; the transverse one-way unlocking mechanism is arranged on the square pressure block.

[0015] Preferably, the sequential quantitative oil supply assembly includes an oil supply box, an oil supply pipe and an oil supply box cover, the oil supply box is arranged on the linkage control assembly, the oil supply box is provided with an upper slide groove that penetrates on both sides, and the oil supply box is also provided with a lower slide groove that penetrates on one side, and a baffle protrusion is provided inside the upper slide groove, one end of the oil supply pipe is connected to the bottom of the oil supply box, and the other end of the oil supply pipe is arranged in a hollow cavity, the oil supply box cover is arranged on the top of the oil supply box, and the oil supply box cover is connected to the oil storage barrel through a pipe on the top.

[0016] By controlling the liquid in the oil supply box through the oil supply control component, a certain amount of lubricating oil can be supplied to the hollow cavity during each jumping cycle of the jumping rod. Since the jumping of the jumping rod is only related to the sliding amplitude of the lifting sliding bracket at this time, the influence of the forging speed on the oil supply in the traditional oil supply system is avoided.

[0017] As a further preferred embodiment of the present invention, the oil supply control assembly includes an upper partition, a lower partition, an upper control spring and a lower control spring. The upper partition is snap-fitted and slidably arranged in the upper slide groove. A tail baffle is provided at the end of the upper partition. A through groove portion is also provided on the upper partition. The width of the through groove portion is smaller than the width of the protruding portion of the baffle. The upper control spring is arranged on the upper partition. The lower partition is snap-fitted and slidably arranged in the lower slide groove. The lower control spring is arranged on the lower partition.

[0018] The compression amounts of the upper control spring and the lower control spring are different. Therefore, when the linkage springboard slides, the movements of the upper partition and the lower partition are actually asynchronous. The oil supply pipeline and the oil supply tank cover alternately pass through the oil storage area between the upper partition and the lower partition, but there is no time for the oil supply pipeline and the oil supply tank cover to pass through. Therefore, the technical purpose of single quantitative oil supply can be achieved.

[0019] Preferably, the oil supply quantity adjustment assembly comprises an adjusting screw and an adjusting slider, the adjusting screw is rotatably arranged on the oil supply box, the adjusting slider is snap-fitted and slidably arranged in the oil supply box, and the adjusting screw and the adjusting slider are threadedly connected.

[0020] By rotating the adjusting screw, the volume occupied by the adjusting slider in the oil supply box can be adjusted, thereby changing the size of the oil storage cavity between the upper partition and the lower partition, and then adjusting the amount of single oil supply to meet different process requirements.

Through the reciprocating sliding of the linkage springboard, the quantitative oil supply mechanism can be controlled to supply lubricating oil into the hollow cavity again and again.

[0025] Through the elastic force of the longitudinal reset spring, the lifting and sliding bracket can be automatically driven to reset when the forging punch is pulled out from the forging workpiece. At the same time, due to the coordination of the positions of the single rod part and the unlocking guide plate, the lifting and sliding bracket can be lifted and lowered back and forth. During the process, the jumping rod will slide along the quadrilateral track in the unlocking guide plate, thereby achieving the technical effect of "the jumping rod periodically jumps to drive the oil supply during the stamping process; the jumping rod does not jump and the oil supply is stopped during the reset process".

[0026] Preferably, the linkage control assembly includes a linkage springboard, a locking card plate and a U-shaped connecting plate, the linkage springboard is symmetrically provided with springboard guide rods corresponding to the longitudinal slide groove, the springboard guide rods are slidably arranged in the longitudinal slide groove, the linkage springboard is also provided with a jumping rod slide groove corresponding to the transverse slide groove, the locking card plate is respectively arranged on both sides of the linkage springboard, the U-shaped connecting plate is fixedly connected to the lifting sliding bracket, the oil supply box is fixedly connected to the U-shaped connecting plate, and the upper control spring and the lower control spring are fixedly connected to the cantilever end of the linkage springboard.

[0027] The relative positions of the jumping rod and the linkage springboard can be limited by the locking card. Under the guidance and limitation of the transverse slide groove and the jumping rod slide groove, the jumping rod crossbar slides laterally relative to the lifting sliding bracket and the linkage springboard. Under the limitation of the locking card, the jumping rod will jump with the linkage springboard at the same time, thereby driving the quantitative oil supply mechanism through the linkage springboard.

[0028] Furthermore, the transverse one-way unlocking mechanism includes an unlocking guide plate and a jumping control assembly, the unlocking guide plate is fixedly connected to the square pressure block, the return spring base is fixedly connected to the unlocking guide plate, a quadrilateral empty groove is provided on the unlocking guide plate, a quadrilateral inner plate is provided in the middle of the quadrilateral empty groove, a connecting column for fixed connection is also provided between the unlocking guide plate and the quadrilateral empty groove, the quadrilateral inner plate is located at the center of the quadrilateral empty groove, and the quadrilateral empty groove and the quadrilateral inner plate form a quadrilateral slide groove.

[0030] The beneficial effects achieved by the present invention using the above structure are as follows:

[0031] (1) The lifting and lowering of the square pressure block can bring the extrusion type oil supply assembly up and down. When the extrusion type oil supply assembly descends, on the one hand, it can extrude and punch the forging workpiece, and on the other hand, it can control the opening and closing of the lubrication oil circuit through the interaction between the forging workpiece and the extrusion type oil supply assembly.

[0032] (2) Through the interaction between the forging workpiece and the quantitative oil supply mechanism, the timing of lubricating oil supply can also be controlled. This supply timing and supply amount are only related to the depth of the forging punch penetrating into the forging workpiece, and the supply amount of this oil supply method is independent of factors such as the forging speed. It can solve the problem of difficult control of lubricating oil supply under different forging requirements and overcome the technical contradiction that the lubricating oil cannot be too much (prone to excessive dirt, excessive cooling and other problems) nor too little (prone to insufficient lubrication, increased wear and other problems).

[0033] (3) By controlling the liquid in the oil supply box through the oil supply control component, a certain amount of lubricating oil can be supplied to the hollow cavity during each jumping cycle of the jumping rod. Since the jumping of the jumping rod is only related to the sliding amplitude of the lifting sliding bracket at this time, the influence of the forging speed on the oil supply in the traditional oil supply system is avoided.

[0034] (4) The compression amounts of the upper control spring and the lower control spring are different. Therefore, when the linkage springboard slides, the movements of the upper baffle and the lower baffle are actually asynchronous. The oil supply pipeline and the oil supply tank cover are alternately connected with the oil storage area between the upper baffle and the lower baffle. However, there is no time for the oil supply pipeline and the oil supply tank cover to be connected. Therefore, the technical purpose of single quantitative oil supply can be achieved.

[0035] (5) By rotating the adjusting screw, the volume occupied by the adjusting slider in the oil supply box can be adjusted, thereby changing the size of the oil storage cavity between the upper partition and the lower partition, and then adjusting the amount of oil supplied at a time to meet different process requirements.

[0036] (6) Through the position sensing and linkage of the lifting control mechanism, the penetration depth of the forging punch can be sensed during the process of the forging punch penetrating into the forging workpiece, and through the coordination of the arc head and the jumping control step, the reciprocating sliding of the linkage springboard can be achieved through the jumping rod. Through the reciprocating sliding of the linkage springboard, the quantitative oil supply mechanism can be controlled to supply lubricating oil into the hollow cavity again and again.

[0037] (7) Through the elastic force of the longitudinal reset spring, the lifting and sliding bracket can be automatically driven to reset when the forging punch is pulled out of the forging workpiece. At the same time, due to the position coordination of the single rod part and the unlocking guide plate, the jumping rod can slide along the quadrilateral track in the unlocking guide plate during the reciprocating lifting and lowering process of the lifting and sliding bracket, thereby achieving the technical effect of "the jumping rod periodically jumps during the stamping process to drive the oil supply; the jumping rod does not jump during the reset process and the oil supply stops".

[0038] (8) The relative position of the jumping rod and the linkage springboard can be limited by the locking card. Under the guidance and limitation of the horizontal slide groove and the jumping rod slide groove, the jumping rod crossbar slides horizontally relative to the lifting sliding bracket and the linkage springboard. Under the limitation of the locking card, the jumping rod will jump with the linkage springboard at the same time, thereby driving the quantitative oil supply mechanism through the linkage springboard.

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0056] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

The closing spring 12 is arranged between the step wall of the hollow cavity 14 and the control valve disc 11. The sealing ring 13 is fixedly connected to the control valve disc 11.

[0060] Through the interaction between the forged workpiece 6 and the quantitative oil supply mechanism 2, the timing of lubricating oil supply can also be controlled. This supply timing and supply amount are only related to the depth of the forging punch 10 penetrating into the forged workpiece 6, and the supply amount of this oil supply method is independent of factors such as the forging speed. It can solve the problem that the supply amount of lubricating oil is difficult to control under different forging requirements, and overcome the technical contradiction that the lubricating oil cannot be too much (prone to excessive dirt, excessive cooling and other problems) nor too little (prone to insufficient lubrication, increased wear and other problems).

The sliding support frame 44 is fixedly connected to the bottom of the lifting sliding support frame 38. A ring portion 51 is provided on the sliding support frame 44. The ring portion 51 is engaged and slidably arranged on the forging punch 10.

[0065] Through the elastic force of the longitudinal reset spring 43, the lifting and sliding bracket 38 can be automatically driven to reset when the forging punch 10 is pulled out from the forging workpiece 6. At the same time, due to the position coordination of the single rod portion 50 and the unlocking guide plate 52, the lifting and sliding bracket 38 can be lifted and lowered back and forth. The jumping rod 40 will slide along the quadrilateral track in the unlocking guide plate 52, thereby achieving the technical effect of "the jumping rod 40 periodically jumps during the stamping process to drive the oil supply; the jumping rod 40 does not jump and the oil supply stops during the reset process".

Under the guidance and limitation of the transverse slide groove 45 and the jumping rod slide groove 60, the cross bar of the jumping rod 40 slides laterally relative to the lifting sliding bracket 38 and the linkage springboard 57. Under the limitation of the locking card plate 58, the jumping rod 40 will jump together with the linkage springboard 57 while jumping, thereby driving the quantitative oil supply mechanism 2 through the linkage springboard 57.

[0072] By controlling the liquid in the oil supply tank 19 through the oil supply control component 17, a certain amount of lubricating oil can be supplied to the hollow cavity 14 during each jumping cycle of the jumping rod 40.

The upper partition 22 is snap-fitted and slidably arranged in the upper slide groove 28. A tail baffle 31 is provided at the end of the upper partition 22. A through groove portion 32 is also provided on the upper partition 22. The width of the through groove portion 32 is smaller than the width of the baffle protrusion 30. The upper control spring 24 is arranged on the upper partition 22, the lower partition 23 is snap-fitted and slidably arranged in the lower slide groove 29, and the lower control spring 25 is arranged on the lower partition 23.

[0074] The compression amounts of the upper control spring 24 and the lower control spring 25 are different. Therefore, when the linkage springboard 57 slides, the movements of the upper partition 22 and the lower partition 23 are actually asynchronous. The oil supply pipeline 20 and the oil supply tank cover 21 are alternately connected with the oil storage area between the upper partition 22 and the lower partition 23. However, there is no time for the oil supply pipeline 20 and the oil supply tank cover 21 to be connected. Therefore, the technical purpose of single quantitative oil supply can be achieved.

[0075] The oil supply quantity adjustment assembly 18 includes an adjustment screw 26 and an adjustment slider 27. The adjustment screw 26 is rotatably arranged on the oil supply box 19, and the adjustment slider 27 is slidably arranged in the oil supply box 19. The adjustment screw 26 and the adjustment slider 27 are threadedly connected.

[0076] By rotating the adjusting screw 26, the volume occupied by the adjusting slider 27 in the oil supply box 19 can be adjusted, thereby changing the size of the oil storage cavity between the upper partition 22 and the lower partition 23, and then adjusting the amount of single oil supply to meet different process requirements.

[0077] When in use, the user first needs to fix the forging workpiece 6 on the forging base 5 through a clamp, and then use the lifting control mechanism 3 inside the forging arm 7 to push the square pressing block 8 and the forging punch 10 down together. When the forging punch 10 squeezes the forging workpiece 6, it can squeeze a hole inside the forging workpiece 6;

[0078] In the initial state, a small amount of lubricating oil is stored in the hollow cavity 14. However, since the control valve flap 11 extends out under the elastic force of the closing spring 12, the lubricating oil in the hollow cavity 14 will not come out of the hollow cavity 14 through the sealing of the sealing ring 13. When the forging punch 10 contacts and squeezes the forging workpiece 6, the control valve flap 11 is completely retracted. At this time, the sealing ring 13 no longer has a sealing effect. After the tapered portion of the control valve flap 11 also fits with the tapered portion of the hollow cavity 14, the control valve flap 11 will not be squeezed by the forging workpiece 6 and continue to retract. Since there is a side groove 15 for liquid flow on the side of the control valve flap 11, some lubricating oil will flow to the contact position between the forging punch 10 and the forging workpiece 6 when they just contact.

[0079] As the forging punch 10 descends, the forging punch 10 slowly penetrates into the forging workpiece 6. At this time, due to the obstruction of the forging workpiece 6, the collar portion 51 will push the lifting sliding bracket 38 to slide upward along the lifting guide rail 36. During the upward sliding process of the lifting guide rail 36, the jumping rod 40 contacts the side of the jumping control plate 39 where the jumping control step 47 is provided. At this time, due to the cooperation between the jumping control step 47 and the arc-shaped head 48, the jumping rod 40 will also jump away from the jumping control plate 39 during the upward sliding process.

[0080] Due to the limit of the locking card plate 58, the jumping rod 40 will jump with the linkage springboard 57 when jumping; at the beginning, the upper partition plate 22 is roughly in a balanced state, and the lower partition plate 23 is in a compressed state. Therefore, when the linkage springboard 57 moves away from the jumping control plate 39, due to the different compression amounts of the upper control spring 24 and the lower control spring 25, the upper control spring 24 will first slide with the linkage springboard 57. When the tail baffle 31 contacts the outer wall of the oil supply box 19, the through groove part 32 has also been completely retracted into the baffle protrusion 30. At this time, the upper and lower spaces of the upper baffle plate 22 are not connected, and the upper baffle plate 22 will not continue to slide;

[0081] At this time, the lower control spring 25 is roughly in a balanced state. As the linkage springboard 57 continues to slide, the lower partition 23 begins to slide along with the linkage springboard 57. At this time, a gap is exposed between the linkage springboard 57 and the inner wall of the oil supply box 19, so that the lubricating oil originally stored between the upper partition 22 and the lower partition 23 flows into the hollow cavity 14 along the oil supply pipe 20 and is transferred to the contact part between the forging workpiece 6 and the forging punch 10.

[0082] When the linkage springboard 57 slides toward the jumping control plate 39 to reset, the action steps of the upper partition 22 and the lower partition 23 are opposite to the above steps. First, the lower partition 23 will slide closed. When the spaces above and below the lower partition 23 are closed to each other, the upper partition 22 will slide along with the linkage springboard 57. When the through groove portion 32 is exposed from the baffle protrusion 30, the oil above the upper partition 22 will enter the interlayer between the upper partition 22 and the lower partition 23. Since the oil supply tank cover 21 and the external oil storage tank are connected, the supply of lubricating oil can be guaranteed.

[0083] When the forging punch 10 penetrates the forging workpiece 6, the linkage springboard 57 will bounce back and forth, thereby achieving the technical purpose of multiple oil supply, because the oil supply pipeline 20 and the oil supply tank cover 21 do not penetrate at the same time, so the amount of oil supplied each time is fixed, so when the forging speed changes, the oil supply amount will not change;

[0084] The quadrilateral empty groove 54 and the quadrilateral inner plate 55 form a quadrilateral slide groove. By designing the corners of the slide groove, the single rod part 50 can be raised and lowered along different longitudinal tracks. When the jumping rod 40 rises, the single rod part 50 slides along the track close to the side of the jumping control step 47, and the jumping of the jumping rod 40 can be achieved through the cooperation of the arc head 48 and the jumping control step 47. When the single rod part 50 slides to the top, it slides into another vertical slide groove through the inclined slide groove. When the jumping rod 40 descends, the single rod part 50 will slide along the track on the other side when it descends, thereby avoiding oil leakage of the forging punch 10 during the rising and resetting stage.

[0085] If the single oil supply volume needs to be changed due to process requirements or other reasons, the volume of the interlayer between the upper partition 22 and the lower partition 23 occupied by the adjusting slider 27 can be changed by rotating the adjusting screw 26, thereby adjusting the oil supply volume each time.
