Description

Technical Field

[0001] This utility model relates to the field of forging processing equipment, and specifically to a cutting device for forging processing. Background Technology

[0002] In the forging industry, cutting is a crucial process. After forging, the shape and dimensions of forgings often need to be further precisely processed by cutting to meet the requirements of subsequent production or use.

[0003] Currently, common forging cutting devices mainly include manual cutting equipment and some more traditional mechanical cutting equipment. Traditional mechanical cutting equipment includes ordinary band saws, etc.

[0004] In forging cutting, traditional cutting devices can only cut the forging. After cutting, the burrs and flash (usually 0.3 to 1 mm high) remaining on the surface of the forging will directly contact the saw blade. When the saw blade moves back and forth at high speed, the sharp burrs can easily scratch the surface of the saw blade and the root of the saw teeth, causing wear on the coating of the saw blade surface and micro-chipping of the saw teeth. Long-term accumulation will lead to a decrease in the cutting accuracy of the saw blade and a shortened service life.

[0005] Therefore, it is necessary to invent a cutting device for forging to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cutting device for forging processing. By integrating a saw blade-grinding blade integrated structure into the cutting assembly, optimizing the saw blade heat dissipation design, and adding auxiliary anti-loosening components, it solves the problems of residual burrs on forgings after cutting, which easily wear down the saw blade; low heat dissipation efficiency of the saw blade, which leads to short service life; and the saw blade fixing bolts, which are easy to loosen due to vibration.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for forging processing, comprising; A fixed frame is fixedly installed on the outside of the device.

[0008] Preferably, the auxiliary component includes a support frame, the support frame is fixedly connected to the left and right sides of the fixed frame close to the fastening bolt, a limiting member is inserted into the inner wall of the support frame, the inner side of the limiting member contacts the outer side of the fastening bolt, a rubber member is fixedly connected to the inner wall of the limiting member, a card slot is formed in the front side of the fastening bolt, and the rubber member is in clamping fit with the card slot.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1 - Figure 3 The cutting device shown includes a fixing frame 1, specifically; The fixed frame 1 is fixedly installed on the outside of the device and directly connected to the main frame of the power component of the forging cutting equipment. It provides a stable mounting carrier for the cutting assembly 3 and auxiliary assembly 2, avoiding cutting deviations caused by device shaking during the cutting process. The fixed frame 1 is equipped with the cutting assembly 3 through the positioning element 4 and the fastening bolt 5, providing a positioning reference for the installation of the saw blade 31, ensuring the accurate installation position of the saw blade 31 on the fixed frame 1, and avoiding cutting deviations caused by the left and right displacement of the saw blade 31. In cooperation with the fastening bolt 5, it forms a fixed constraint on the saw blade 31 from different directions, enhancing the stability of the saw blade 31 during the cutting process and preventing the saw blade 31 from moving up and down. The auxiliary assembly 2 is set on the outside of the fastening bolt 5. The cutting assembly 3 includes the saw blade 31, which is inserted into the inner wall of the fixed frame 1. The right side is set with saw teeth. As the component that directly contacts the forging, it realizes the cutting processing of the forging through high-speed reciprocating motion and is the core execution component of the cutting device. The saw blade 31 has mounting slots on both sides, and the positioning piece 4 passes through the mounting slots of the saw blade 31. The front and rear sides of the saw blade 31 have heat dissipation slots 33, which can increase the contact area between the saw blade 31 and the air, accelerate the dissipation of frictional heat during the cutting process, and prevent the saw blade 31 from deforming, decreasing in hardness, or accelerating wear due to overheating. The heat dissipation slots 33 are arc-shaped slots. The arc structure is easier to guide airflow than right-angle slots, which can blow away the metal chips generated during cutting away from the surface of the saw blade 31 in time, preventing the chips from accumulating and blocking the heat dissipation channel, and reducing the wear of the saw blade 31 cutting edge by the chips. The lower left side of the saw blade 31 is fixedly connected to a grinding strip 32 for grinding the cutting area of ​​the forging. The grinding strip 32 has a grinding groove on the outer side. The grinding groove on the outer side can directly grind the burrs and flash on the cutting surface while the saw blade 31 is cutting the forging, realizing the integration of "cutting + grinding" and reducing the damage of burrs to the saw blade 31.

[0019] like Figure 1 - Figure 3As shown, the auxiliary component 2 includes a support frame 21, which is fixedly connected to the left and right sides of the fixed frame 1 near the fastening bolt 5. The support frame 21 is L-shaped, and the lower part of the support frame 21 is closed, providing vertical support and horizontal guidance for the limiting member 22, ensuring that the limiting member 22 can be accurately inserted into and fit the fastening bolt 5. The limiting member 22 is inserted into the inner wall of the support frame 21. The limiting member 22 is U-shaped. After being inserted into the inner wall of the support frame 21, its inner side directly contacts the outer side of the fastening bolt 5, forming a "ring-like" constraint on the bolt from both sides, restricting the bolt's rotation. A groove is reserved on its inner wall for fixing the rubber part 23. The rubber component 23 is precisely aligned with the slot 24 of the bolt. The inner side of the limiting component 22 contacts the outer side of the fastening bolt 5. The inner wall of the limiting component 22 is fixedly connected to the rubber component 23, which can perfectly fit the arc-shaped inner side of the slot 24. The elastic deformation of the rubber fills the gap, forming an "elastic snap-fit", which avoids the limiting component 22 from loosening due to cutting vibration. The front side of the fastening bolt 5 has a slot 24. The contact surface between the rubber component 23 and the slot 24 is set as an arc-shaped surface. The inner side of the slot 24 is set as an arc, and the arc-shaped inner side matches the arc-shaped surface of the rubber component 23, providing a precise snap-fit ​​position for the rubber component 23 and forming a physical locking point. The rubber component 23 and the slot 24 snap-fit ​​together.

[0020] The working principle of this practical application is as follows: The fixed frame 1 is rigidly connected to the main power frame of the forging cutting equipment to ensure the stability of the overall structure. Then, the saw blade 31 of the cutting component 3 is aligned with the positioning piece 4 on the fixed frame 1 through the mounting slots on the left and right sides, so that the saw blade 31 is accurately positioned at the preset cutting position. Then, the fastening bolt 5 is threadedly connected to the inner wall of the positioning piece 4 to initially lock the position of the saw blade 31. At this time, the "U"-shaped limiting piece 22 of the auxiliary component 2 needs to be inserted into the lower closed structure of the bottom support frame 21 along the inner wall of the L-shaped support frame 21 to ensure that the limiting piece 22 is in place, so that the inner side of the limiting piece 22 fits against the outer side of the fastening bolt 5. At the same time, the rubber part 23 on its inner wall is precisely engaged with the arc-shaped groove 24 on the front side of the fastening bolt 5. The arc-shaped surface of the rubber part 23 is completely fitted with the inner side of the groove 24, forming a double fixation through elastic deformation to prevent the fastening bolt 5 from loosening due to subsequent cutting vibration.

[0021] After the device is started, the power system of the forging cutting equipment drives the saw blade 31 to reciprocate at high speed. The saw teeth on the right side of the saw blade 31 contact the part of the forging to be cut, and the forging is cut through the frictional shearing action between the saw teeth and the metal. During this process, the arc-shaped heat dissipation grooves 33 on the front and rear sides of the saw blade 31 play a role simultaneously: on the one hand, the arc structure increases the contact area between the saw blade 31 and the air, accelerates the dissipation of heat generated by cutting friction, and prevents the saw blade 31 from becoming less hard or deformed due to overheating; on the other hand, the high-speed movement of the saw blade 31 drives the airflow to flow along the heat dissipation grooves 33, which can blow away the metal debris generated by cutting away from the surface of the saw blade 31 in time, avoiding the accumulation of debris that blocks the heat dissipation channel or wears down the saw teeth of the saw blade 31, thus ensuring stable cutting efficiency.

[0022] Meanwhile, the grinding strip 32 on the lower left side of the saw blade 31 moves synchronously with the saw blade 31: when the saw blade 31 moves forward to cut the forging, the grinding groove on the outer side of the grinding strip 32 will be in close contact with the newly formed cutting surface of the forging. Through the friction between the grinding groove and the cutting surface, the rough structures such as burrs and flash on the cutting surface are directly removed, realizing the integrated cutting-grinding process. This reduces the processing steps and avoids damage to the saw teeth of the saw blade 31 by burrs, thus extending the service life of the saw blade 31.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
