Description

Technical Field

[0001] The utility model relates to the field of nickel-chromium alloy production, and more specifically to a forging device which can be precisely positioned and is used in the production of nickel-chromium alloy. Background Art

[0002] Chromium alloy has high strength and corrosion resistance. The alloy composed of iron and nickel is commonly known as stainless steel. Chromium-nickel alloy has a wide range of uses, including in the manufacture of aerospace parts. In the production process of chromium-nickel alloy aerospace parts, forging is an indispensable link. Forging is a processing method that uses forging machinery to apply pressure to metal billets to cause them to undergo plastic deformation in order to obtain forgings with certain mechanical properties, shapes and sizes.

[0003] China Patent Authorization Announcement No.: CN212443048U, provides a forging device for the production of chromium-nickel alloy aerospace parts. This patent rotates the rotating shaft through a driving device, and the turntable rotates along the annular groove. The fixed ring plays a guiding and supporting role, which helps to stabilize the rotation process of the turntable; the first connecting member and the second connecting member are deflected and drive the movable rod to move in the vertical direction. The impact head performs multiple forging processes on the chromium-nickel alloy aerospace parts, which helps to improve the forging effect, is simple to operate, and saves time and effort.

[0004] When the above-mentioned forging device is in use, the chromium-nickel alloy parts to be forged are directly placed on the turntable for forging. However, during the forging process, no positioning components are set for limiting the parts, which makes it easy for the parts to shift or fall off during the forging process, thereby reducing the forging effect of the parts and the forging device. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a forging device that can be precisely positioned for the production of nickel-chromium alloys. It can achieve this by fixing a synchronously lifting positioning component on the outside of a lifting shaft that drives the forging head to lift and lower. When the forging head moves down to forge the workpiece, multiple positioning rocker bars on the positioning component slide outward and spread out. When the forging head moves up, the current direction of the electromagnet is changed to make the electromagnet and the magnetic block at the upper end of the positioning rocker bar magnetically attracted, and then the multiple positioning rocker bars slide inward and reset, and the bottom of the positioning rocker bar can push the workpiece to move toward the center, which can effectively prevent the workpiece from being displaced after multiple forgings. The arrangement of this structure can improve the forging quality of nickel-chromium alloy workpieces, improve the safety of the forging device, and prevent materials from slipping.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A forging device with precise positioning for nickel-chromium alloy production comprises a fixed seat, mounting frames are fixedly installed on both sides of the upper end of the fixed seat, a lifting control mechanism is fixedly installed on the middle part of the upper end of the mounting frame, a lifting shaft is slidably installed on the middle part of the lower end of the lifting control mechanism, a forging head is fixedly installed on the lower end of the lifting shaft, a positioning assembly is fixedly installed on the lower end of the outer side of the lifting shaft, the positioning assembly comprises a fixed plate, the fixed plate is installed on the lower end of the outer side of the lifting shaft by a fixed connection, and the fixed plate is located above the forging head, a baffle is fixedly installed on the lower end of the fixed plate, the baffle and the fixed plate are both circular in shape, and the diameter of the baffle is smaller than the diameter of the fixed plate, and positioning rocker arms are rotatably installed on the four ends of the outer side of the baffle.

[0010] Furthermore, a ball is rotatably installed in the middle of the lower end of each of the positioning swing rods, a magnetic block is fixedly embedded in the inner upper end of the positioning swing rod, and an electromagnet is fixedly embedded at the four ends inside the baffle, and the electromagnet is magnetically connected to the magnetic block.

[0011] Furthermore, a positioning auxiliary component is installed on the upper end of the fixed plate, and the positioning auxiliary component includes a spring, an outer sleeve and a movable sleeve. The two springs are installed on both sides of the upper end of the fixed plate by a fixed connection method, the outer sleeve is installed on the upper end of the spring by a fixed connection method, and the movable sleeve is installed on the lower end of the outer sleeve by a sliding connection method, and the outer diameter of the movable sleeve is adapted to the inner diameter of the outer sleeve, and the movable sleeve is movably sleeved on the outside of the fixed plate.

[0012] Furthermore, limiting grooves are provided on both sides of the outer sleeve, an electric push rod is fixedly installed on the top of the limiting groove, an output shaft is provided at the lower end of the electric push rod, limiting sliders are fixedly installed on the upper ends of both sides of the movable sleeve, the limiting sliders are movably clamped in the limiting grooves, and the limiting sliders are fixedly connected to the output shaft of the electric push rod, a pressure sensor is fixedly embedded at the lower end of the right side of the movable sleeve, and a controller is fixedly installed on the left side of the upper end of the mounting frame, and the controller is electrically connected to the pressure sensor, the electric push rod and the electromagnet.

[0013] 3. Beneficial effects

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) This solution can be achieved by fixing a synchronously lifting positioning assembly on the outside of a lifting shaft that drives the forging head to lift and lower. When the forging head moves downward to forge the workpiece, multiple positioning rocker arms on the positioning assembly slide outward and spread out. When the forging head moves upward, the current direction of the electromagnet is changed so that the electromagnet and the magnetic block at the upper end of the positioning rocker arm are magnetically attracted to each other, and then multiple positioning rocker arms slide inward and reset. The bottom of the positioning rocker arm can push the workpiece to move toward the center, which can effectively prevent the workpiece from shifting after multiple forgings. The arrangement of this structure can improve the forging quality of nickel-chromium alloy workpieces, improve the safety of the forging device, and prevent materials from slipping.

[0016] (2) In the default state, the spring stretches, pushing the outer sleeve and the movable sleeve to the upper end of the baffle and the positioning rocker. However, when the forging head drives the positioning assembly and the positioning auxiliary assembly to move upward, the top of the outer sleeve abuts against the bottom of the lifting control mechanism and squeezes the spring to contract, so that the outer sleeve and the movable sleeve move downward relatively, the movable sleeve is sleeved on the outside of the positioning rocker, and the auxiliary positioning rocker swings inward for storage.

[0017] (3) In the default state, the output shaft of the electric push rod extends, pushing the limit slider to the lower end of the limit groove, so that the outer sleeve and the movable sleeve extend. However, when the movable sleeve moves down and presses on the outer sides of multiple positioning rocker arms, the pressure sensor can monitor the contact pressure between the movable sleeve and the positioning rocker arm in real time. When the material is clamped at the lower end of the positioning rocker arm, the positioning rocker arm cannot continue to be retracted. Then, the pressure value detected by the pressure sensor exceeds the normal value. The pressure sensor promptly sends an alarm signal to the controller, and the controller controls the electric push rod to start. As the outer sleeve continues to move down, the electric push rod drives the movable sleeve to move up and be retracted into the outer sleeve, which can effectively prevent the positioning rocker arm from being violently damaged by the positioning auxiliary component. The setting of the positioning auxiliary component enhances the stability of the positioning rocker arm. BRIEF DESCRIPTION OF THE DRAWINGS

First, place the workpiece to be forged at the middle position of the upper end of the fixed seat 1, and the lifting control mechanism 3 can drive the lifting shaft 5 and the forging head 6 to lift and lower. The forging head 6 continuously strikes and forges the workpiece. When the forging head 6 is lifted and lowered, the positioning assembly 7 can be driven to lift and lower synchronously. The bottoms of multiple positioning rocker rods 73 on the outside of the positioning assembly 7 are abutted against the upper end of the fixed seat 1. The positioning rocker rods 73 open and close inside and outside while lifting and lowering. When the positioning assembly 7 moves upward, the multiple positioning rocker rods 73 close inwardly under the action of gravity, and the workpieces are gathered and moved toward the middle, helping to position the workpieces toward the center.

[0030] See also Figure 2-3 and Figure 5 , a ball 74 is rotatably installed at the middle part of the lower end of the plurality of positioning swing rods 73, a magnetic block 731 is fixedly embedded at the inner upper end of the positioning swing rod 73, and an electromagnet 721 is fixedly embedded at the four ends inside the baffle 72, and the electromagnet 721 is magnetically connected to the magnetic block 731. When in use, by arranging a ball 74 at the bottom of the positioning swing rod 73, the positioning swing rod 73 can be assisted to slide on the upper end of the fixing seat 1, thereby strengthening the protection of the positioning swing rod 73 and the fixing seat 1; at the same time, through the arrangement of the magnetic block 731 and the electromagnet 721, the electromagnet 721 and the magnetic block 731 can be magnetically attracted and repelled, which is used to assist the plurality of positioning swing rods 73 to perform opening and closing movements, and increase the inward movement of the positioning swing rod 73, so as to help the positioning swing rod 73 push the material to move, thereby improving the positioning effect of the material and the use effect of the positioning assembly 7.

[0031] See also Figure 2-4The upper end of the fixed plate 71 is provided with a positioning auxiliary component 8, which includes a spring 81, an outer sleeve 82 and a movable sleeve 83. The two springs 81 are fixedly connected to both sides of the upper end of the fixed plate 71, the outer sleeve 82 is fixedly connected to the upper end of the spring 81, and the movable sleeve 83 is mounted on the lower end of the outer sleeve 82 by a sliding connection. The outer diameter of the movable sleeve 83 matches the inner diameter of the outer sleeve 82, and the movable sleeve 83 is movably sleeved on the outer side of the fixed plate 71. When in use, in the default state, the spring 81 is extended to push the outer sleeve 82 and the movable sleeve 83 to be located at the upper ends of the baffle plate 72 and the positioning swing rod 73. However, when the forging head 6 drives the positioning component 7 and the positioning auxiliary component 8 to move upward, the top of the outer sleeve 82 abuts against the bottom of the lifting control mechanism 3 and squeezes the spring 81 to contract, then the outer sleeve 82 and the movable sleeve 83 move downward relatively, and the movable sleeve 83 is sleeved on the outer side of the positioning swing rod 73, and the auxiliary positioning swing rod 73 is swung inward for storage.

[0032] Limiting grooves 821 are provided on both sides of the outer sleeve 82, and an electric push rod 822 is fixedly installed on the top of the limiting groove 821, and an output shaft is provided at the lower end of the electric push rod 822. Limiting sliders 831 are fixedly installed on the upper ends of both sides of the movable sleeve 83, and the limiting slider 831 is movably clamped in the limiting groove 821, and the limiting slider 831 is fixedly connected to the output shaft of the electric push rod 822. A pressure sensor 832 is fixedly embedded at the lower end of the right side of the movable sleeve 83, and a controller 4 is fixedly installed on the left side of the upper end of the mounting frame 2. The controller 4 is electrically connected to the pressure sensor 832, the electric push rod 822 and the electromagnet 721. When in use, the output shaft of the electric push rod 822 is extended in the default state, pushing the limiting slider 831 to be located at the lower end of the limiting groove 821, so that the outer sleeve 8 2 and the movable sleeve 83 are extended, but when the movable sleeve 83 moves down and presses on the outer sides of the multiple positioning rocker rods 73, the pressure sensor 832 can monitor the contact pressure between the movable sleeve 83 and the positioning rocker rod 73 in real time. When the lower end of the positioning rocker rod 73 clamps the material, the positioning rocker rod 73 cannot continue to be accommodated, and the pressure value detected by the pressure sensor 832 exceeds the normal value. The pressure sensor 832 sends an alarm signal to the controller 4 in time, and the controller 4 controls the electric push rod 822 to start. As the outer sleeve 82 continues to move downward, the electric push rod 822 drives the movable sleeve 83 to move up and be accommodated in the outer sleeve 82, which can effectively prevent the positioning rocker rod 73 from being violently damaged by the positioning auxiliary component 8.

When the forging head 6 moves down to strike and forge the material, the controller 4 can change the current direction of the electromagnet 721, so that the electromagnet 721 and the magnetic block 731 repel each other, and the multiple positioning swing rods 73 open outward, and when the forging head 6 moves up, the current direction of the electromagnet 721 is continuously changed, so that the electromagnet 721 and the magnetic block 731 attract each other, and the multiple positioning swing rods 73 slide inward and gather together, and the lower end of the positioning swing rod 73 clamps the material, and pushes the material to move to the middle of the upper end of the fixed seat 1 to help the material positioning. At the same time, the positioning auxiliary component 8 moves upward, the top of the outer sleeve 82 abuts against the bottom of the lifting control mechanism 3, and the spring 81 is squeezed to contract, so that the outer sleeve 82 and the movable sleeve 83 move downward relatively, and the movable sleeve 83 is sleeved on the outside of the positioning rocker 73, and the auxiliary positioning rocker 73 swings inward and is stored, thereby improving the stability of the positioning rocker 73.
