Description

Technical Field

[0001] This utility model relates to the technical field of metal plastic forming equipment, and in particular to a precision forming machine for peritectic steel forging. Background Technology

[0002] The peritectic steel forging precision forming machine is a specialized piece of equipment used in the metal processing field for precision forging and roundness correction of peritectic steel materials. During the plastic forming process of peritectic steel, a mechanical jaw is typically used to hold the workpiece and rotate it, while a high-frequency hammering mechanism simultaneously strikes the rotating workpiece to ultimately achieve the predetermined precision dimensions and roundness requirements.

[0003] In the aforementioned precision forming process, the hammer block, as the core actuator of the hammering mechanism, needs to come into direct contact with the high-temperature workpiece and withstand high-frequency, high-intensity impact forces. This harsh working environment makes the hammer block a highly wear-prone consumable part.

[0004] Once the working end face of the hammer block wears or deforms, any slight change in its shape will be directly transmitted to the workpiece, resulting in a serious decrease in the precision of the molded product, making it unable to meet the requirements of precision molding. Therefore, in order to ensure machining accuracy in continuous production, worn hammer blocks must be frequently inspected and periodically replaced.

[0005] However, in existing technical solutions, hammer blocks are typically secured using traditional bolt fastening or complex integrated installation methods. When hammer blocks need to be replaced, maintenance personnel must first disassemble the relevant protective covers, hydraulic lines, or other associated transmission components. The entire disassembly and assembly process is extremely cumbersome and requires significant downtime. This inefficient maintenance method not only severely reduces the overall production efficiency of the equipment but also greatly increases the labor intensity and time costs of manual maintenance.

[0006] Therefore, this utility model proposes a precision forming machine for peritectic steel forging to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the precision forming machine for peritectic steel forging, such as the cumbersome and time-consuming replacement and maintenance process of the hammer block as a vulnerable part, resulting in long equipment downtime, and the fact that the waste generated during the forging process easily accumulates at the bottom of the equipment, affecting its service life and being inconvenient to clean, this utility model aims to provide a peritectic steel forging precision forming machine with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a precision forming machine for peritectic steel forging rounds, including: a casting machine, a mechanical claw located on one side of the casting machine, a quick-release mechanism located on one side of the mechanical claw, and a base plate located below the quick-release mechanism; and a cleaning mechanism located on the upper surface of the base plate.

[0009] The cleaning mechanism comprises a motor, a disk driven to rotate by the motor, a first connecting rod rotatably connected to the eccentric position of the disk, a second connecting rod rotatably connected to the end of the first connecting rod, a slider rotatably connected to the end of the second connecting rod away from the first connecting rod, a slide groove formed on the base plate for the slider to slide, and a movable plate fixedly connected to the top of the slider as part of the linkage structure.

[0010] Furthermore, the quick-release mechanism specifically includes a housing, a hydraulic rod installed inside the housing, a hammer block connected to the end of the hydraulic rod, a fixed plate, a rotating shell one, a movable column threadedly connected to the rotating shell one, a rotating shell two sleeved on the outside of the movable column, and a rotating shell three; a rigid column is fixed to the outer wall of the movable column, and a cross groove is opened at the bottom of the rotating shell three for the rigid column to be engaged or disengaged; the fixed plate, the rotating shell two, and the rotating shell three are combined by rotating the rotating shell one to drive the movable column to rise and fall, and by cooperating with rotating the rotating shell three to align the rigid column with the cross groove, thereby realizing the locking or disengagement of the rotating shell two from the fixed plate.

[0011] Preferably, the housing has a processing cavity inside for accommodating the hammer block and the molten casting, and a discharge port is provided on one side of the housing for discharging the formed peritectic steel; the discharge port and the mechanical claw are located on opposite sides of the housing, and the mechanical claw is used to clamp the molten casting and feed it into the housing.

[0012] Preferably, the fixing plate is fixedly connected to the outer wall of the shell, and a fixing bracket is provided on one side of the hammer block. The fixing bracket is detachably pressed and fixed to the fixing plate by the cooperation of rotating shell two and rotating shell three, thereby realizing the stable installation and quick disassembly of the hammer block.

[0013] Preferably, the cross-shaped groove includes a through groove penetrating the bottom wall of the rotating housing and a positioning groove formed on the inner side of the bottom wall of the rotating housing with a specific depth; the through groove is used for the hard column to pass through during disassembly, and the positioning groove is used to restrict the rotation of the hard column in the working state to ensure the stability of the locked state.

[0014] Preferably, the first rotating shell is rotatably connected above the fixed plate, and the movable column passes through the first rotating shell and extends into the interior of the second and third rotating shells; when the first rotating shell rotates, the movable column is restricted from rotating and moves in the vertical direction, thereby driving the components below to perform axial displacement.

[0015] Preferably, the chute extends along the length of the base plate, and the slider and the moving plate are driven by the second connecting rod to perform reciprocating linear motion in the chute; the bottom surface of the moving plate is attached to the upper surface of the base plate to push the waste away from the base plate and achieve automatic cleaning.

[0016] Preferably, the motor is fixedly mounted on one end of the base plate via a motor mount, the disc is horizontally positioned, and the two ends of the first connecting rod are respectively hinged to the disc and the second connecting rod via pins to form a stable crank-slider transmission structure.

[0017] Preferably, the mechanical claw is equipped with a rotary drive mechanism. When the mechanical claw grips the molten casting and extends into the housing, it can drive the molten casting to rotate. The hydraulic rod drives the hammer block to radially strike the rotating molten casting to ensure the uniformity of the forging process.

[0018] This utility model has the following beneficial effects: 1.

Detailed Implementation

[0023] Example: Refer to Figures 1 to 4 This utility model provides a precision forming machine for peritectic steel forging rounds, which aims to solve the problems in the prior art where the accumulation of peritectic steel forging round waste affects the equipment life and the complex and time-consuming replacement and maintenance after the hammer blocks are damaged.

[0024] like Figure 1 As shown, the peritectic steel forging precision forming machine includes a casting machine 1, a mechanical claw 4 located on one side of the casting machine 1, a quick-release mechanism 3 located on one side of the mechanical claw 4, and a base plate 21 located below the quick-release mechanism 3. The base plate 21 is used to receive the scrap material falling during forging. The mechanical claw 4 is equipped with a rotation drive mechanism. The mechanical claw 4 is used to clamp the casting and feed it into the housing 38 of the quick-release mechanism 3, and drive the casting to rotate. The peritectic steel forging precision forming machine also includes a cleaning mechanism 2 located on the upper surface of the base plate 21.

[0025] Reference Figure 2 and Figure 3 The cleaning mechanism 2 includes a motor 22, which is fixedly mounted on one end of the base plate 21 via a motor mount. The motor 22 drives the horizontally positioned disc 23 to rotate. The two ends of the first connecting rod 24 are respectively hinged to the eccentric position of the disc 23 and the second connecting rod 25 via pins. The second connecting rod 25 is rotatably connected to the slider 26. A groove 27 extending along the length of the base plate 21 is provided on the base plate 21. The slider 26 is slidably disposed in the groove 27. A movable plate 28 is fixedly connected to the slider 26. The bottom surface of the movable plate 28 is in contact with the upper surface of the base plate 21. The slider 26 and the movable plate 28 reciprocate linearly within the groove 27 under the drive of the second connecting rod 25, which is used to push the waste away from the base plate 21.

[0026] Reference Figure 1 , Figure 3 and Figure 4The quick-release mechanism 3 includes a housing 38, inside which a processing cavity is formed for accommodating the hammer block 32 and the molten casting. A discharge port 39 for discharging the formed peritectic steel is provided on one side of the housing 38. This discharge port 39 and the mechanical claw 4 are located on opposite sides of the housing 38. A hydraulic rod 31 is installed inside the housing 38, which drives the hammer block 32 to radially strike the rotating molten casting. The quick-release mechanism 3 also includes a fixed plate 35, a rotating housing 33, a moving column 34, and a rotating... The moving shell 36 and the rotating shell 37 are included. The moving column 34 is threadedly connected to the rotating shell 33. The rotating shell 36 and the rotating shell 37 are sleeved on the outside of the moving column 34. A rigid column is fixed on the outer wall of the moving column 34. A cross groove is opened at the bottom of the rotating shell 37 for the rigid column to be inserted or removed. The moving column 34 is driven to rise and fall by rotating the rotating shell 33, and the rigid column is aligned with the cross groove by rotating the rotating shell 37, so as to realize the locking or disengagement between the rotating shell 36 and the fixed plate 35.

[0027] Reference Figure 3 and Figure 4 The fixing plate 35 is fixedly connected to the outer wall of the housing 38, serving as the load-bearing base for the entire quick-release structure. One side of the hammer block 32 is integrally formed or welded with a fixing bracket, which is tightly attached to the surface of the fixing plate 35 in the installed state. To achieve rapid pressing and releasing of the fixing bracket, the rotating housing 33 is rotatably connected to the top of the fixing plate 35, and the moving column 34 vertically passes through the central hole of the rotating housing 33 and extends downward. The outer circumferential surface of the moving column 34 is machined with external threads, and the inner hole surface of the rotating housing 33 is machined with matching internal threads, forming a threaded transmission fit. This threaded fit structure ensures that when the rotating housing 33 rotates in the horizontal plane, the moving column 34 can move up and down axially, thereby providing the axial tension required for locking.

[0028] Meanwhile, rotating shell 2 36 and rotating shell 37 are coaxially sleeved on the lower part of moving column 34. Rotating shell 2 36 is located below fixed plate 35 and is used to directly contact and press the fixed bracket of hammer block 32. Rotating shell 37 is located below rotating shell 2 36 and has a cross groove on its bottom end face. The cross groove specifically includes a through groove that penetrates the bottom wall of rotating shell 37 and a positioning groove with only a partial depth that extends in the circumferential direction. Correspondingly, a rigid column is fixed on the outer wall of moving column 34 near the bottom end. In the assembled state, the rigid column can be accommodated in the positioning groove, so that rotating shell 37 cannot detach from moving column 34 in the axial direction. Then, the upward movement of moving column 34 drives rotating shell 37 to push rotating shell 2 36 upward, and finally the fixed bracket of hammer block 32 is firmly locked on fixed plate 35.

[0029] In a preferred embodiment, the interior of the housing 38 is formed with a processing cavity for accommodating the hammering block 32 and the molten casting. This processing cavity provides a relatively sealed space for the molten casting to be forged into a round shape. A discharge port 39 is provided on the side of the housing 38 away from the mechanical claw 4. The discharge port 39 is used to discharge the formed peritectic steel, ensuring continuous production. At the same time, the mechanical claw 4 is provided with a rotary drive mechanism. When the molten casting is inserted into the housing 38, the mechanical claw 4 can drive the molten casting to rotate around its own axis to ensure that the hammering block 32 strikes the molten casting evenly.

[0030] In another preferred embodiment, the fixing plate 35 is fixedly connected to the outer wall of the housing 38 by bolts, and is used as the reference and force-bearing surface of the quick-release mechanism 3; a fixing bracket is provided on one side of the hammer block 32. In the locked state, the fixing bracket is pressed against the inner side of the fixing plate 35 by rotating the bottom edge of the housing 36. This engagement method achieves strong clamping of the fixing bracket of the hammer block 32 through the axial tension provided by the locking assembly, so that the hammer block 32 can remain stable when subjected to the high-frequency impact of the hydraulic rod 31, and is easy to replace.

[0031] As another preferred embodiment, the specific structure of the cross-shaped groove at the bottom of the rotating shell 37 is configured as follows: it includes two through grooves that intersect each other and penetrate the bottom wall of the rotating shell 37, and two positioning grooves that are only opened on the inner side of the bottom wall of the rotating shell 37; the positioning groove has a specific depth and extends a certain arc length in the circumferential direction; this groove structure, in conjunction with the rigid post on the moving post 34, allows the rotating shell 37 to disengage from the moving post 34 when the rigid post is aligned with the through groove in the disassembled state, and in the working locking state, when the rigid post is rotated to be inserted into the positioning groove, the circumferential wall surface of the positioning groove restricts the rotation of the rigid post, thereby fixing the entire locking assembly in the locking position.

[0032] In another preferred embodiment, the rotating housing 33 is rotatably connected to the top of the fixed plate 35 via a bearing, which ensures the smooth rotation of the rotating housing 33; after the moving column 34 is threadedly connected to the rotating housing 33, the moving column 34 is provided with a guide or limiting structure to prevent its rotation, so that the rotation of the rotating housing 33 can be purely converted into the axial lifting and lowering movement of the moving column 34, providing a precise reset and unlocking stroke for the locking assembly.

[0033] As another preferred embodiment, the chute 27 extends along the length of the base plate 21, providing a precise reciprocating linear motion track for the slider 26 and the moving plate 28, ensuring the efficiency of waste cleaning; the bottom surface of the moving plate 28 is designed as a scraper and fits against the upper surface of the base plate 21, which can effectively push the waste generated during the hammering of the molten casting to one side of the base plate 21.

[0034] As another preferred embodiment, motor 22 is a servo motor, which is fixedly mounted on the external support structure on one side of the base plate 21 via a motor mount, providing stable power output to the disc 23; connecting rod 1 24 and connecting rod 25 are hinged by a pin, forming the connecting rod part in the crank-slider mechanism, the length and connection position of which are precisely designed to ensure that the reciprocating stroke of the moving plate 28 can cover the waste accumulation area.

[0035] As another preferred embodiment, the hydraulic rod 31 has the ability to reciprocate at high frequency, which is used to drive the hammer block 32 to radially strike the rotating molten casting. The hammer block 32 is preferably made of high-hardness wear-resistant alloy steel or tungsten carbide alloy to cope with long-term impact and high-temperature wear.

[0036] The working principle is as follows: When the peritectic steel forging is fed into the casting machine 1, its plastic casting body is held at the tail by the mechanical claw 4. Then the mechanical claw 4 is activated and drives the casting body to rotate, while the casting body extends into the housing 38. At this time, the hydraulic rod 31 is activated, and the hydraulic rod 31 drives the hammer block 32 to strike the rotating casting body at high frequency. The casting body is formed under the combined action of hammering and rotation, and is discharged through the discharge port 39. During the hammering process, the waste material falling from the casting body will accumulate above the bottom plate 21. At this time, the motor 22 of the cleaning mechanism 2 is activated, and the motor 22 drives the disc 23 to rotate. The disc 23 converts the circular motion into reciprocating motion through the transmission mechanism composed of connecting rod 1 24 and connecting rod 25, and drives the slider 26 to slide inside the slide groove 27. The slider 26 drives the fixedly connected moving plate 28 to move back and forth on the bottom plate 21, thereby realizing the automatic cleaning of waste material and solving the problem of waste material accumulation affecting the equipment life.

[0037] When the hammering block 32 needs to be replaced due to damage caused by prolonged high-frequency impact, the operator first rotates the rotating shell 33. Utilizing the threaded transmission between the rotating shell 33 and the moving column 34, the moving column 34 moves axially downwards. The rigid column fixed to the outer wall of the moving column 34 then extends downwards through the cross-shaped slot at the bottom of the rotating shell 37. Subsequently, the operator rotates the rotating shell 37, causing the through slot in the cross-shaped slot to align with the trajectory of the rigid column. At this point, the rigid column is no longer restricted by the positioning slot in the cross-shaped slot, and the rotating shell 37 and rotating shell 36 can axially disengage from the moving column 34. After the rotating shell 36 disengages, its clamping force on the fixing bracket of the hammering block 32 disappears, allowing the fixing bracket to be removed from the fixing plate 35, thus achieving quick disassembly of the hammering block 32. During installation, the reverse steps are repeated, with the rigid column engaging the positioning slot and being clamped by the rotating shell 36. This quick-release mechanism 3 solves the problem of complex and time-consuming replacement of the hammering block 32.
