Description

Technical Field

[0001] The utility model relates to the technical field of die steel processing, in particular to a die steel processing positioning device. Background Art

[0002] Die steel is a type of steel used to make cold stamping dies, hot forging dies, die casting dies and other dies. Die steel can be roughly divided into three categories: cold rolled die steel, hot rolled die steel and plastic die steel, which are used for forging, stamping, cutting, die casting and so on. Due to the different uses of various dies and complex working conditions, the die steel should have high hardness, strength, wear resistance, sufficient toughness, high hardenability, hardenability and other process properties according to the working conditions of the dies it manufactures.

[0003] When mold steel is further processed, it is usually cut by cutting equipment before being put into further use. The shape of this mold steel is generally a long rod or column, and it is cut along its radial direction. Due to the high hardness of mold steel, cutting takes a long time, and a positioning fixture that can fix the mold steel is required to prevent the mold steel from shaking during cutting.

[0004] In the clamps for fixing mold steel in the prior art, the clamping effect of mold steel is not good during the cutting process, which easily causes small-scale shaking, thereby affecting the accuracy of its processing. Moreover, after the long strip or rod mold steel is cut, it involves continued feeding, and this process also involves repeated opening and closing of the clamps. This makes ordinary clamps, such as conventional clamps that only clamp two or three sides of the rod mold steel, not only affect the processing accuracy after clamping due to unstable clamping position and inaccurate positioning, but also the repeated clamping operation and the unloading operation involved in this process will also affect the overall processing efficiency. In addition, the cutting end of the mold steel is easily broken and flew away due to the high-speed rotation of the cutting tool, and the operation is very dangerous. In order to improve the above situation, it is necessary to design a mold steel processing positioning device. Utility Model Content

[0053] The processing end protection structure is arranged on the upper surface of the processing positioning platform 1 and located on one side of the fixed end fixture 3 to shield and protect the rod mold steel located on one side of the fixed end fixture 3, and also has a limiting effect on the fixed end fixture 3.

[0054] Specifically, during operation, the device aligns the rod mold steel with the fixed end clamp 3 and the force end clamp 4 and adjusts the position, and drives the force end clamp 4 to move toward the fixed end clamp 3 through the force driving mechanism until it is clamped and fixed, and then radially clamps the rod mold steel through the radial clamping and positioning mechanism to fix it perpendicular to the axial direction of the mold steel to complete the positioning and fixation of the mold steel. During processing, the processing end protection structure shields and protects the top of the rod mold steel located on one side of the fixed end clamp 3 to prevent the mold steel from being blown away and threatening the safety of the operator.

[0055] Furthermore, the fixed end clamp 3 and the force end clamp 4 clamp the two ends of the rod mold steel so that the rod mold steel is fixed perpendicular to the extension direction of the processing tool avoidance groove 2, so that when the force end clamp 4 pushes the mold steel to move axially, the feeding is completed to perform continuous cutting operations.

[0061] Furthermore, the radial clamping and positioning mechanism comprises:

[0066] After the force driving mechanism positions the mold steel, manually shake the second driving turntable 14 to drive the second threaded rod 12 to rotate and engage with the first assembly block 11, so that the second threaded rod 12 moves along its axial direction, and then drives the clamping push block 13 to move toward the fixed side clamping block 10. During this process, the fixed side clamping block 10 and the clamping push block 13 work together to clamp the rod mold steel radially to position and fix it.

[0067] Furthermore, the processing end protection structure includes:

[0068] A first fixed top plate 15 is fixedly disposed on the upper surface of the machining positioning platform 1 and is located on the opposite side of the fixed end fixture 3 to the side where the force-applying end fixture 4 is located.

[0069] A second fixed top plate 17 is fixedly disposed on the upper surface of the processing positioning platform 1 and is located on the opposite side of the first fixed top plate 15 where the fixed end fixture 3 is located. A second guide hole 18 is opened on the second fixed top plate 17;

[0074] Specifically, in the process of driving the force-applying end clamp 4 to cooperate with the fixed end clamp 3 to clamp the fixed mold steel through the force-applying drive mechanism, the force-applying end clamp 4 is first moved to rest on the first fixed top plate 15. At this time, the position of the force-applying end clamp 4 is fixed under the limit of the first fixed top plate 15, and at the same time, the guide rod 19 and the limit pressure plate 20 are driven to move, and the first compression spring 21 is compressed. In the process of the fixed end clamp 3 moving, the horizontal protective baffle 22 moves in the through hole 23 until the force-applying end clamp 4 rests on the first fixed top plate 15 and the horizontal protective baffle 22 extends from the through hole 23 to the top of the mold steel, so as to shield the upper part of the mold steel and prevent the mold steel from collapsing. Then the force-applying end clamp 4 is reset by the first compression spring 21 to continue the subsequent operation.

[0075] Furthermore, a mold steel ejection mechanism is provided on the upper surface of the processing positioning platform 1 to eject the cut rod mold steel for blanking, and the mold steel ejection mechanism includes:

[0080] The second compression spring 28 is sleeved on the push rod 25 and compressed between the push button 26 and the second assembly block 24 .

[0081] Specifically, after the end of the mold steel is cut off, the push button 26 is manually pushed to drive the push rod 25 to slide in the second assembly block 24, so as to drive the ejector head 27 to move and eject the cut mold steel out of the processing position so that the subsequent mold steel can be loaded for further processing. In this process, the second compression spring 28 is compressed so that after the push button 26 is released, the push rod 25, the push button 26 and the ejector head 27 are reset for subsequent use.

[0082] Furthermore, a positioning baffle 29 is provided on the upper surface of the processing positioning platform 1. The positioning baffle 29 is located between the fixed end clamp 3 and the force end clamp 4 to limit the side position of the rod mold steel for processing positioning. The positioning baffle 29 is distributed on one side or both sides of the mold steel along the axial direction of the rod mold steel to assist in positioning the mold steel and prevent the mold steel from deviating from the position.
