Description

Technical Field

[0001] The utility model relates to the technical field of free forging control, in particular to a free forging lower flat anvil. Background Art

[0002] Free forging products are a processing method that uses pressure to make the metal deform freely in all directions between the upper and lower anvil surfaces to obtain forgings of the desired shape, size and certain mechanical properties without any restrictions. Generally, the operator controls the console to control the up and down movement of the movable crossbeam of the press. The upper flat anvil is installed on the movable crossbeam, and the lower flat anvil is placed on the movable workbench. During forging, the movable crossbeam is controlled to move up and down to achieve the change of the distance between the upper and lower flat anvils, thereby achieving the change of the size of the forging product.

[0003] Announcement No. CN220112253U A free forging lower anvil includes a lower anvil body, a positioning frame, and a positioning pad. The positioning frame can be detachably arranged on the lower anvil body. A positioning hole is arranged at the center of one end of the positioning frame away from the lower anvil body. The positioning pad can be detachably arranged on the positioning frame through the positioning hole. The positioning frame is provided with a groove matching the lower anvil body, and guide tail grooves are arranged on both sides of the groove. Corresponding lifting holes are arranged on two opposite side walls of the positioning frame. The positioning pad includes a positioning rod and a support column, and a chamfer is arranged on the end of the positioning rod away from the support column.

[0004] The above-mentioned free forging lower flat anvil is provided with a positioning frame and a positioning pad on the lower flat anvil. According to the size set for each forging, a positioning pad of corresponding size is selected and set on the positioning frame to make a reference for the forging size. The size of the forging blank can be accurately positioned, the forging accuracy can be improved, the size of different parts of the forging blank can be avoided to be different in size and the appearance can be fluctuated, the forging margin can be reduced, and raw materials can be avoided to be wasted. However, the device cannot forge beyond the size of the groove under the positioning frame, which reduces its practicality. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a free forging lower flat anvil.

[0006] The utility model is implemented by the following technical scheme: a free forging lower flat anvil, comprising a main body mechanism, a positioning mechanism is arranged on the top of the main body mechanism, and a pressing mechanism is penetrated inside the positioning mechanism;

[0007] The main body mechanism comprises a lower anvil body, a first fixing groove is provided on the top of the lower anvil body, a fixing column runs through the top of the lower anvil body, and a groove is provided on the top of the lower anvil body.

[0008] Through the above technical solution, the fixed column and the first fixed groove, because the six faces of the hexagonal fixed column are all planes, the contact surface between the fixed column and the groove is large, and the force at the six points is relatively uniform, so it can effectively prevent the rotational force of the object, prevent the relative movement of the lower anvil body and the limit frame, and provide higher stability, especially when subjected to external vibration or impact. The flat contact surface can help disperse and reduce the impact of external forces, thereby maintaining the position and posture of the object. The first fixed groove and the fixed column are designed as hexagons to increase the strength and stability of the entire structure. They ensure the accurate matching of the relative position and direction of the two parts, reduce errors during installation, and improve assembly accuracy.

[0009] As a further improvement of the above scheme, the positioning mechanism includes a limit frame, a positioning hole is provided on the top of the limit frame, a second fixing groove is provided inside the limit frame, a lifting block is provided on the side of the limit frame, and a protrusion is provided at the bottom of the limit frame.

[0010] Through the above technical solution, the limit frame can be replaced to enlarge the empty slot between the lower flat anvil body and the limit frame after installation, so that different sizes can be forged, which improves work efficiency, saves personnel strength, and can accurately locate the forging billet size.

[0011] As a further improvement of the above solution, the pressing mechanism includes a positioning rod, a limiting column is arranged on the top of the positioning rod, and a chamfer is arranged on the bottom of the positioning rod.

[0012] Through the above technical solution, the limiting column can prevent the forging from being over-forged, thereby improving the forging accuracy.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model sets a fixing column and a first fixing groove. Since the six faces of the hexagonal fixing column are all planes, the contact surface between the fixing column and the groove is large, and the force at the six points is relatively uniform, so it can effectively prevent the rotational force of the object, prevent the relative movement of the lower flat anvil body and the limit frame, and provide higher stability, especially when subjected to external vibration or impact. The flat contact surface can help disperse and reduce the influence of external forces, thereby maintaining the position and posture of the object. The first fixing groove and the fixing column are designed as hexagons to increase the strength and stability of the entire structure. They ensure the accurate matching of the relative position and direction of the two parts, reduce errors during installation, and improve assembly accuracy.

[0015] The utility model provides grooves and protrusions, which can be aligned with each other. The cooperation between the protrusions and the grooves increases the contact area between the lower anvil body and the limit frame, providing better support and stability. This helps prevent the lower anvil body and the limit frame from moving under shock or vibration, reducing the risk of accidental falling off or loss of control. The design of the protrusions and grooves effectively reduces the impact of vibration on the lower anvil body and the limit frame by increasing friction and bite. They can absorb and disperse vibration energy, thereby improving the anti-vibration performance of the structure.

[0016] The utility model provides a limit frame, which can be replaced to enlarge the empty slot between the lower flat anvil body and the limit frame after installation, so that different sizes can be forged, the work efficiency is improved, the physical strength of the personnel is saved, and the size of the forging blank can be accurately positioned.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Example:

[0027] Please combine Figure 1-6 A free forging lower flat anvil of this embodiment includes a main body mechanism 1, a positioning mechanism 2 is arranged on the top of the main body mechanism 1, and a pressing mechanism 3 is penetrated inside the positioning mechanism 2;

[0028] The main body mechanism 1 comprises a lower anvil body 101 , a first fixing groove 102 is provided at the top of the lower anvil body 101 , a fixing column 103 penetrates the top of the lower anvil body 101 , and a groove 104 is provided at the top of the lower anvil body 101 .

[0029] The first fixing groove 102 is hexagonal in shape, and the fixing column 103 is hexagonal in shape.

[0030] The positioning mechanism 2 includes a limiting frame 201 , a positioning hole 202 is formed on the top of the limiting frame 201 , a second fixing groove 203 is formed inside the limiting frame 201 , a hanging block 204 is formed on the side of the limiting frame 201 , and a protrusion 205 is formed on the bottom of the limiting frame 201 .

[0031] The limiting frame 201 is located on the top of the lower flat anvil body 101, and the second fixing groove 203 is hexagonal in shape.

[0032] There are two lifting blocks 204 , which are respectively located on the left and right sides of the limiting frame 201 .

[0033] The pressing mechanism 3 comprises a positioning rod 301 , a limiting column 302 is arranged at the top of the positioning rod 301 , and a chamfer 303 is arranged at the bottom of the positioning rod 301 .

[0034] The positioning rod 301 passes through the interior of the limiting frame 201 , the positioning rod 301 is fixedly connected to the limiting column 302 , and the chamfer 303 is located at an end of the positioning rod 301 away from the limiting column 302 .

[0035] The implementation principle of a free forging lower anvil in the embodiment of the present application is: the limit frame 201 is lifted by the lifting block 204, different limit frames 201 are selected according to the size of the forging, and the forging body is placed in the empty groove between the limit frame 201 and the lower anvil body 101. The protrusion 205 at the bottom of the limit frame 201 is engaged with the groove 104 at the top of the lower anvil body 101. The mutual cooperation of the protrusion 205 and the groove 104 increases the contact area between the limit frame 201 and the lower anvil body 101, providing better support and stability. This helps prevent the lower anvil body 101 and the limit frame 201 from moving under shock or vibration, reducing the risk of accidental falling off or loss of control. The fixing column 103 is then placed in the first fixing groove 102 and the second fixing groove 203 to fix the limit frame 201 and the lower anvil body 101. Because the six faces of the hexagonal fixing column 103 are all planes, the contact surface with the groove 104 is large, and the force at the six points is relatively uniform, so it can effectively prevent the rotational force of the object, prevent the relative movement of the lower anvil body 101 and the limit frame 201, and can provide higher stability, especially when subjected to external vibration or impact. The flat contact surface can help disperse and reduce the influence of external forces, thereby maintaining the position and posture of the object. The first fixing groove 102 and the fixing column 103 are designed as hexagons to increase the strength and stability of the entire structure. They ensure the accurate matching of the relative position and direction of the two parts, reduce the error in the installation process, and improve the assembly accuracy. In the pressing mechanism 3 replaced according to different forging requirements, the positioning rod 301 is inserted into the positioning hole 202 on the limit frame 201, so as to place the limit column 302 on the limit frame 201, and then the upper anvil is controlled to move downward for forging. By replacing the pressing mechanism 3 with different heights, the forging thickness of the forging is controlled each time forging is performed, and during the downward forging process of the upper anvil, when the upper anvil contacts the upper surface of the limit column 302, the limit frame 201 also provides a certain support force to prevent the upper anvil from stopping forging in time, over-forging the forging, and deviating too much from the set size.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
