Description

Technical Field

[0001] This utility model relates to the field of edge trimming die technology, and in particular to an edge trimming die for metal forgings. Background Technology

[0002] Metal forgings are metal parts with specific geometric dimensions and shapes obtained by using pressure equipment and dies to cause partial or complete plastic deformation of billets or ingots. The structure and properties of metal parts processed by forging can be effectively improved. However, forged metal parts often require subsequent processing such as trimming, grinding, and cleaning. Among these processes, trimming dies are needed to fix the metal forgings during trimming.

[0003] Currently, most existing metal forging trimming dies achieve their desired effect using the following technologies;

[0004] Guiding and positioning technologies, including guide wheel guidance and laser ranging positioning;

[0005] Mold structure design technology, including arc mold structure and multi-blade step-by-step cutting structure;

[0006] Drive and transmission technologies, including electric actuator drives and gear drives;

[0007] Cushioning and protection technologies include spring cushioning and mold plate cushioning.

[0008] Currently, existing edge-cutting dies have been found to have at least the following problems in actual use;

[0009] Currently, most existing trimming dies use a threaded screw structure to clamp and fix the metal forgings. However, when changing the metal forgings, this fixing method requires adjusting the screw to disengage it from the metal forging before the metal forging can be removed from the die. Adjusting the screw requires turning it many times, which takes a lot of time and affects processing efficiency. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a metal forging trimming die, which solves the problem of existing trimming dies affecting processing efficiency.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A metal forging trimming mold includes a base, a turntable fixedly connected to the top surface of the base, a bottom mold fixedly connected to the top of the turntable, a cylindrical metal forging placed inside the bottom mold, a fixed frame fixedly connected to one side of the base, two limiting blocks for limiting the position fixedly connected to the top surface of the fixed frame away from the base, a rotating shaft seat fixedly connected to the side of the base away from the fixed frame, a stop block for cooperating with a rear component for rotation fixedly connected to the top of the rotating shaft seat, connecting shafts fixedly connected to both ends of the rotating shaft seat, a connecting seat fixedly connected to the end of the two connecting shafts away from the rotating shaft seat, a movable frame fixedly connected to the connecting seat, and a clamping mechanism for fixing the cylindrical metal forging provided above the bottom mold.

[0013] The clamping mechanism includes a lead screw, a parallel bearing, and a rubber gasket.

[0014] Preferably, a limit block is fixedly connected to the end of the movable frame away from the connecting seat.

[0015] Preferably, both limiting blocks have through holes on their surfaces, and the limiting card block also has through holes on its surface.

[0016] Preferably, a groove is formed between the two limiting blocks, the limiting block is adapted to the groove, and the through hole of the limiting block is aligned with the through holes of the two limiting blocks.

[0017] Preferably, a threaded sleeve is fixedly connected to one end of the movable frame near the limiting block, and the threaded sleeve, the cylindrical metal forging, the bottom mold and the clamping mechanism all share the same central axis.

[0018] Preferred configuration: The threaded sleeve is connected to the lead screw via a threaded connection.

[0019] Preferably, the lead screw is fixedly connected to the parallel bearing, the side of the parallel bearing away from the lead screw is fixedly connected to the rubber gasket, and the end of the lead screw away from the parallel bearing is fixedly connected to a handwheel. The handwheel drives the lead screw to rotate spirally on the threaded sleeve until the rubber gasket is pressed into contact with the top surface of the cylindrical metal forging.

[0020] Preferably, the through hole of the limiting block and the through holes of the two limiting blocks are connected together by a plug rod, and the plug rod is connected to the through hole to restrict the limiting block and the limiting block from being separated.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] I. In this application, when a new cylindrical metal forging needs to be replaced for edge trimming, the insert rod is directly pulled out, and the movable frame is rotated 90 degrees based on the connecting shaft. At this time, the threaded sleeve will not obstruct the cylindrical metal forging, and the cylindrical metal forging can be directly removed and replaced with a new one. After the replacement is completed, the limiting block and the limiting block are re-limited by the insert rod, and the clamping mechanism remains unchanged. It can directly press and contact the new cylindrical metal forging through the rubber gasket. Compared with the existing edge trimming mold, this application has the advantage of simple operation and solves the problem of existing edge trimming molds affecting processing efficiency.

[0023] Second, this application, by setting a rotatable movable frame and connecting seat, allows for the direct pulling out of the insertion rod and pulling the movable frame to rotate 90 degrees based on the connecting shaft when it is necessary to perform edge trimming operations on a large cylindrical metal forging. At this time, the threaded sleeve will not obstruct the cylindrical metal forging. In conjunction with the adjustable clamping mechanism, this application can fix cylindrical metal forgings of different lengths, making this application highly applicable.

[0030] This application provides a metal forging trimming die, which effectively solves the problem of existing trimming dies affecting processing efficiency.

[0031] Example

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem of existing trimming dies affecting processing efficiency. The overall idea is as follows:

[0033] To address the problems existing in the prior art, this utility model provides a metal forging trimming mold, including a base 1, a turntable 2 fixedly connected to the top surface of the base 1, a bottom mold 201 fixedly connected to the top of the turntable 2, a cylindrical metal forging 3 placed inside the bottom mold 201, a fixing frame 4 fixedly connected to one side of the base 1, two limiting blocks 401 for limiting the position fixedly connected to the top surface of the fixing frame 4 away from the base 1, a rotating shaft seat 6 fixedly connected to the side of the base 1 away from the fixing frame 4, a stop block 602 for cooperating with the rear component for rotation fixedly connected to the top of the rotating shaft seat 6, connecting shafts 601 fixedly connected to both ends of the rotating shaft seat 6, a connecting seat 7 fixedly connected to the end of the two connecting shafts 601 away from the rotating shaft seat 6, a movable frame 701 fixedly connected to the connecting seat 7, and a clamping mechanism 8 for fixing the cylindrical metal forging 3 is provided above the bottom mold 201.

[0034] The clamping mechanism 8 includes a lead screw 801, a parallel bearing 803, and a rubber pad 804.

[0035] The end of the movable frame 701 away from the connecting seat 7 is fixedly connected to the limit block 703.

[0036] Both limit blocks 401 have through holes 9 on their surfaces, and the limit block 703 also has through holes 9 on its surface.

[0037] A groove is formed between the two limiting blocks 401, and the limiting block 703 is adapted to the groove. The through hole 9 of the limiting block 703 is aligned with the through hole 9 of the two limiting blocks 401.

[0038] A threaded sleeve 702 is fixedly connected to one end of the movable frame 701 near the limit block 703. The threaded sleeve 702, the cylindrical metal forging 3, the bottom mold 201 and the clamping mechanism 8 all share the same central axis.

[0039] The threaded sleeve 702 is threadedly connected to the lead screw 801.

[0040] The lead screw 801 is fixedly connected to the parallel bearing 803. The side of the parallel bearing 803 away from the lead screw 801 is fixedly connected to the rubber gasket 804. The end of the lead screw 801 away from the parallel bearing 803 is fixedly connected to the handwheel 802. The handwheel 802 drives the lead screw 801 to rotate spirally on the threaded sleeve 702 until the rubber gasket 804 is pressed into contact with the top surface of the cylindrical metal forging 3.

[0041] The through hole 9 of the limiting block 703 and the through holes 9 of the two limiting blocks 401 are connected together with the insert rod 5. The insert rod 5 is connected to the through hole 9 to restrict the limiting block 401 and the limiting block 703 from being separated.

[0042] Base 1: As the basic support part of the entire device, it provides a stable installation platform for components such as turntable 2, fixed frame 4, and rotating shaft seat 6, ensuring the stability of the entire cutting mold device during operation.

[0043] Turntable 2: Installed on the top surface of base 1, with bottom mold 201 fixedly connected to its top, it can support cylindrical metal forging 3, and turntable 2 may provide some rotation convenience for subsequent edge cutting operations, assist in adjusting the position of forging, and cooperate to complete edge cutting processing at different angles.

[0044] Cylindrical metal forging 3: This is the workpiece to be trimmed. It is placed in the bottom mold 201 and subsequently fixed by the clamping mechanism 8. It undergoes the trimming process to remove excess scrap and obtain a finished product that meets the precision requirements.

[0045] Fixed frame 4: Fixed to one side of the base 1, the two limiting blocks 401 on the top surface of the end away from the base 1 are used to cooperate with the limiting block 703 of the movable frame 701 to initially limit the position of the movable frame 701, assist in stabilizing the clamping mechanism 8, and ensure reliable fixing of the cylindrical metal forging 3.

[0046] Insert rod 5: Passes through the through holes 9 of the limiting block 703 and the two limiting blocks 401, tightly connecting the limiting block 703 and the limiting blocks 401 together, preventing the movable frame 701 from accidentally dislodging during the trimming process, ensuring the stability of the entire clamping structure, and maintaining the clamping state of the forging.

[0047] Rotary shaft seat 6: Installed on the side of the base 1 away from the fixed frame 4, the connecting shafts 601 at both ends are used to cooperate with the connecting seat 7 to rotate, so that it can rotate flexibly. The stop block 602 at the top can block and limit the rotation of the connecting seat 7 to a certain extent, and control the rotation range of the movable frame 701.

[0048] Connecting seat 7: As an intermediate connecting part, it allows the movable frame 701 to rotate smoothly around the connecting shaft 601, thereby driving the clamping mechanism 8 to move and realize the clamping and releasing operation of the cylindrical metal forging 3.

[0049] Clamping mechanism 8: used to fix the cylindrical metal forging 3. The lead screw 801 rotates in the threaded sleeve 702, and pushes the rubber pad 804 with the help of the parallel bearing 803, so that it presses against the top surface of the forging, and firmly clamps the forging by friction, ensuring the stability of the forging position when cutting the edge.

[0050] Through hole 9: It is formed on the surface of the limiting block 401 and the limiting block 703 to provide a fitting space for the insertion rod 5. Through the cooperation of the insertion rod 5 and the through hole 9, the limiting block 401 and the limiting block 703 are accurately positioned and securely connected, maintaining the structural stability of the entire device.

[0051] Bottom mold 201: Fixed on the top of turntable 2, it provides a placement position for cylindrical metal forging 3 and serves as a positioning base, allowing the forging to be accurately positioned in the preset position for the edge cutting operation, and cooperates with clamping mechanism 8 to complete the preparation for subsequent processing.

[0052] Limiting block 401: Located on the fixed frame 4, a groove is formed between the two limiting blocks 401, which is adapted to and engaged with the limiting block 703. At the same time, it cooperates with the through hole 9 and the insertion rod 5 to limit the position of the movable frame 701, creating conditions for the stable operation of the clamping mechanism 8.

[0053] Connecting shaft 601: Enables the rotating shaft seat 6 and connecting seat 7 to be rotatably connected, giving the connecting seat 7 and the connected movable frame 701 the ability to rotate, so that the movable frame 701 can rotate flexibly around the shaft, which facilitates the clamping and releasing of the cylindrical metal forging 3.

[0054] Stop 602: Located at the top of the rotating shaft seat 6, it limits the rotation range of the connecting seat 7 to prevent the connecting seat 7 and the movable frame 701 from rotating excessively, thus preventing damage to the device due to excessive rotation and maintaining the safety of the device operation.

[0055] Movable frame 701: One end is connected to the connecting seat 7, and the other end is provided with a limit block 703. The threaded sleeve 702 in the middle cooperates with the lead screw 801. By rotating itself, it drives the clamping mechanism 8 to move, so as to realize the clamping or loosening operation of the cylindrical metal forging 3.

[0056] Threaded sleeve 702: Fixed on the movable frame 701, forming a threaded connection with the lead screw 801. When the lead screw 801 rotates, it provides guidance and support for the linear movement of the lead screw 801, causing the rubber gasket 804 to move closer to or away from the cylindrical metal forging 3.

[0057] Limiting block 703: Located at one end of the movable frame 701, it engages with the limiting block 401 of the fixed frame 4 and is inserted into the groove. It also connects with the insertion rod 5 through its own through hole 9 and the through hole 9 of the limiting block 401 to stabilize the position of the movable frame 701 and ensure that the clamping mechanism 8 acts on the forging.

[0058] Lead screw 801: Connected to handwheel 802, it rotates within threaded sleeve 702 and drives rubber pad 804 to move linearly with the help of parallel bearing 803. It is a key transmission component for realizing the clamping and releasing actions of clamping mechanism 8 and adjusting the clamping force on cylindrical metal forging 3.

[0059] Handwheel 802: Fixed to one end of lead screw 801, allowing operators to manually apply force and rotate lead screw 801, enabling operators to easily control the clamping and releasing process of clamping mechanism 8, thus improving the convenience of operation.

[0060] Parallel bearing 803: Connected between lead screw 801 and rubber pad 804, it ensures the stability of lead screw 801 during rotation and accurately transmits the axial force of lead screw 801 to drive rubber pad 804 to move smoothly and achieve stable clamping.

[0061] Rubber gasket 804: It comes into direct contact with the cylindrical metal forging 3. It is soft and elastic, which can increase the friction with the forging to ensure a stable clamping, and avoid damage to the surface of the forging, thus protecting the appearance of the workpiece from damage.

[0062] Working principle:

[0063] The first step is to place the cylindrical metal forging 3 on the bottom mold 201, and then drive the movable frame 701 and the connecting seat 7 to rotate based on the connecting shaft 601, so that the limiting block 703 is engaged between the two limiting blocks 401. Insert the insert rod 5 into the through hole 9 for limiting. Drive the screw 801 to rotate on the threaded sleeve 702 through the handwheel 802 until the rubber gasket 804 is pressed and contacted with the top surface of the cylindrical metal forging 3. At this time, the cylindrical metal forging 3 is pressed and fixed by the clamping mechanism 8. Then, the cylindrical metal forging 3 can be trimmed.

[0064] The second step is to directly pull out the insert rod 5 and pull the movable frame 701 to rotate 90 degrees based on the connecting shaft 601. At this time, the threaded sleeve 702 will not block the cylindrical metal forging 3, and the cylindrical metal forging 3 can be directly removed and replaced with a new one. After the replacement is completed, the limiting block 703 and the limiting block 401 can be re-limited by the insert rod 5. The clamping mechanism 8 has not changed and can directly press and contact the new cylindrical metal forging 3 through the rubber gasket 804.

[0065] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
