Technical Field

[0001] The utility model relates to the technical field of numerical control hammers, in particular to a numerical control hammer for forging. Background Art

[0002] CNC full hydraulic die forging hammer, also known as CNC electro-hydraulic hammer, program-controlled hammer or CNC hammer, can realize arbitrary adjustment of striking energy, extend the working life of die and hammer rod, and reduce vibration by more than 80%. It has been widely used in automobiles, motorcycles, hardware tools, engineering machinery, surgical instruments, stainless steel tableware, slings and rigging, coal mining machinery, agricultural machinery, ships, railways, aerospace and other industries.

[0003] When the existing CNC hammer for forging is used, it will be controlled by a driving device to hammer the forging piece downward so that the forging piece reaches the corresponding shape. However, when the CNC hammer is used for hammering for a long time, the CNC hammer itself will be damaged and deformed under the high-intensity force, resulting in the need to disassemble the CNC hammer as a whole during subsequent maintenance and repair, which reduces the subsequent processing efficiency. For this reason, we propose a CNC hammer for forging processing. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a numerical control hammer for forging processing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a CNC hammer for forging processing, comprising a support seat, a fitting groove, a driving device and a driving rod, a CNC hammer that fits and slides with the inside of the fitting groove is installed at the bottom of the driving rod, a protective disassembly base is provided at the bottom of the CNC hammer, an assembly screw groove that penetrates the disassembly base is opened at the top of the CNC hammer, and the internal thread of the assembly screw groove is installed with an assembly bolt for disassembling and fixing the disassembly base.

[0006] Preferably, when the driving device is started to drive the CNC hammer to move downward through the driving rod, the disassembly and assembly base at the bottom of the CNC hammer is in the first contact state with the surface of the forging part.

[0007] Preferably, the bottom of the CNC hammer is provided with a protective pad which is molded with the outside of the assembly bolt, and the protective pad itself has a deformation property;

[0008] Furthermore, when the bottom of the disassembly and assembly base is in compression contact with the forging piece, the protective pad at the bottom of the CNC hammer is in a compressive deformation state, and the bottom of the CNC hammer is in a deformation buffering state through the protective pad.

[0009] Preferably, a buffer pad is provided on the thread surface of the assembly bolt, and the buffer pad itself has deformation characteristics;

[0010] Furthermore, when the assembly bolt is threadedly connected with the interior of the assembly screw groove, the buffer pad on the thread surface of the assembly bolt is in a threaded engagement state with the interior of the assembly screw groove.

[0011] Preferably, the outer sleeve of the driving rod is provided with a plurality of groups of limiting support sleeves for limiting and restraining the driving rod, and the outer periphery of the limiting support sleeve is provided with a support arm connected to the inner side support of the fitting groove.

[0012] Preferably, the limiting support sleeve has a limiting groove inside, and the bottom of the driving device is provided with limiting grooves penetrating through multiple groups of limiting support sleeves.

[0013] Beneficial Effects

[0014] The utility model provides a CNC hammer for forging, which has the following beneficial effects:

[0015] 1. A CNC hammer for forging processing. In this article, a disassembly base is provided at the bottom of the CNC hammer. After the disassembly base is connected with the protective pad at the bottom of the CNC hammer, the assembly bolts can be threadedly connected and installed in the assembly screw grooves inside the CNC hammer and the disassembly base, and the disassembly base is installed to the bottom of the CNC hammer. At this time, when the CNC hammer is used to process the forged part, the disassembly base can first contact the forged part to avoid direct contact between the CNC hammer and the forged part, and the protective pad can be used to assist in buffering the hammering force, and the buffer pad on the surface of the assembly bolt can assist in buffering the vibration force to avoid damage to the assembly bolt itself.

[0016] 2. A CNC hammer for forging processing, wherein the outer sleeve of the driving rod is provided with multiple sets of limit support sleeves. When the driving rod is driven by a driving device to control the CNC hammer to slide downward, the multiple sets of limit support sleeves can limit and restrain the driving rod itself when it is subjected to the resonance force of hammering, thereby ensuring the vertical effect of the driving rod itself and preventing the driving rod from being deformed and bent under pressure. A limit support rod connected to the bottom support of the driving device is arranged in a limit groove inside the multiple sets of limit support sleeves. The limit support rod can assist in increasing the limiting stability of the limit support sleeve, thereby achieving the effect of improving the vertical stability protection of the driving rod itself.
