Description

Technical Field

[0001] This utility model belongs to the field of forging die technology, and in particular relates to a forging die for alloy drill bit blanks. Background Technology

[0002] Forging dies for alloy drill bit blanks are molds used to process cemented carbide materials, primarily for manufacturing blanks for alloy drill bits. The main purpose of forging dies for alloy drill bit blanks is to obtain the desired shape and size by placing the blank into a forging die and subjecting it to plastic deformation under high temperature and external force through forging.

[0003] In the actual forging process of carbide drill bit blanks, due to the wide variety of drill bit sizes and models, die replacement is a common and necessary operation. The traditional die replacement method typically involves loosening multiple bolts distributed around the circumference of the die holder to remove the die, then placing a new die in the holder and retightening the bolts to fix the die's position. While this traditional method can complete the die replacement, it has some significant drawbacks in practical applications.

[0004] 1. In the traditional mold replacement process, workers need to loosen the bolts one by one and remove the mold, which is often a very tedious and time-consuming process;

[0005] 2. Since the mold is fixed by tightening bolts one by one, the entire mold replacement process takes a long time. Especially when the mold is frequently changed during production, the extended operation time will directly affect production efficiency.

[0006] 3. Uneven tightening force of multiple bolts during installation can cause minor deformation or loosening of the mold. This can affect the contact stability between the mold and the mold base, thus affecting the precision of the forging process and potentially leading to inconsistent product quality.

[0007] 4. Bolts may loosen under long-term high temperature and heavy load working environment, which not only affects the fixing effect of the mold, but may also cause safety hazards.

[0008] To address the aforementioned problems, this application proposes a forging die for alloy drill bit blanks. Utility Model Content

[0009] The purpose of this invention is to provide a forging die for alloy drill bit blanks, which solves the problems mentioned in the background art.

[0010] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0011] This utility model relates to a forging die for alloy drill bit blanks, including a die base, in which a die is detachably mounted. A die core is integrally formed inside the die. A locking component is provided between the die base and the die. An ejector component is provided inside the die base to push the die upward from the die base.

The locking component includes an annular groove formed outside the die, a locking pin that slides horizontally in the die base, and a rotating seat that is rotatably connected in the die base.

[0012] Furthermore, the locking component also includes a clearance groove opened inside the rotating seat at one end. A movable plug is slidably provided inside the clearance groove. A long bolt is provided between the movable plug and the clearance groove, passing through the movable plug and being screwed into the rotating seat.

[0013] Furthermore, the locking pin engages with the annular groove, and the locking pin can also enter the clearance groove and disengage from the annular groove.

[0014] Furthermore, the ejector component includes a gear fixed to the bottom of the rotating seat and a slide that slides horizontally inside the mold base, with a rack fixed to the inner side of the slide to mesh with the gear.

[0015] Furthermore, the front end of the slide is connected to a top block via an ejector spring, and the front end of the top block is provided with an inclined surface of an extrusion die.

[0016] Furthermore, the positioning mechanism includes a polygonal rod fixed to the upper end of the rotating seat and a polygonal sleeve fitted onto the upper end of the polygonal rod. A positioning block is fixed to the side of the polygonal sleeve, and a handle located above the mold base is fixed to the top of the polygonal sleeve.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Please see Figure 1-5 As shown, this utility model is a forging die for alloy drill bit blanks, including a die base 1, a die 2 detachably installed in the die base 1, a die core 21 integrally formed inside the die 2, a locking component 3 provided between the die base 1 and the die 2, an ejector component 4 provided inside the die base 1 to push the die 2 upward from the die base 1, and a positioning mechanism 5 provided at the upper end of the die base 1. The locking component 3, the ejector component 4 and the positioning mechanism 5 are linked together. The locking component 3 includes an annular groove 31 opened on the outside of the die 2, a locking pin 32 that slides horizontally in the die base 1, and a rotating seat 33 that is rotatably connected in the die base 1.

[0034] The locking component 3 also includes a relief groove 34 that is opened inside the rotating seat 33 and has one end open. A movable plug 35 is slidably provided inside the relief groove 34. A 36 is provided between the movable plug 35 and the relief groove 34. A long bolt 37 passes through the movable plug 35 and is screwed and locked to the rotating seat 33.

[0035] The locking pin 32 engages with the annular groove 31, and the locking pin 32 can also enter the relief groove 34 and disengage from the annular groove 31. When the locking pin 32 and the relief groove 34 are coaxial, the locking pin 32 can enter the interior of the relief groove 34 after being subjected to force. When the two are not coaxial, the locking pin 32 is always engaged with the annular groove 31, thereby ensuring the stability of the mold 2 installation.

[0036] The ejection component 4 includes a gear 41 fixed to the bottom of the rotating seat 33 and a slide 42 that slides horizontally inside the mold base 1. A rack 43 that meshes with the gear 41 is fixed inside the slide 42. The gear 41 and the rack 43 can use the rotation of the rotating seat 33 to store force on the ejection spring 45, thereby achieving the effect of leveraging force and ultimately achieving the purpose of ejecting the mold 2.

[0037] The slide block 42 is connected to the front end of the ejector spring 45 via the ejector spring 45. The front end of the ejector spring 44 is provided with the inclined surface of the extrusion mold 2. When the ejector spring 45 is charged, the inclined surface of the front end of the ejector spring 44 can push the mold 2 upward from the mold base 1, thereby making it easier to remove the mold 2.

[0038] The positioning mechanism 5 includes a polygonal rod 51 fixed to the upper end of the rotating seat 33 and a polygonal sleeve 52 fitted onto the upper end of the polygonal rod 51. The polygonal rod 51 and the polygonal sleeve 52 can move up and down while transmitting circumferentially. Then, under the action of the positioning block 53 and the positioning sleeve 55, the locking component 3 is positioned. The positioning block 53 is fixed to the side of the polygonal sleeve 52, and the handle 54 located above the mold base 1 is also fixed to the top of the polygonal sleeve 52. The positioning sleeve 55 fitted onto the outside of the polygonal sleeve 52 is fixed inside the mold base 1. The positioning block 53 and the positioning sleeve 55 cooperate to position the rotation angle of the rotating seat 33, thereby ensuring the precise docking of the clearance groove 34 and the locking pin 32.

[0039] The positioning sleeve 55 has a fixed distance groove 56 inside and a positioning groove 57 at the top of one end of the fixed distance groove 56. A positioning spring 58 is also provided between the polygonal rod 51 and the polygonal sleeve 52. The positioning spring 58 is used to insert the positioning block 53 into the positioning groove 57 to achieve the final positioning effect.

[0040] Understandably, by setting a locking component, the mold can be easily locked and released in the mold base, which is simple to operate and has a reliable structure. At the same time, the ejector component can push the mold upward when the locking component is disengaged, making it easy to remove. The positioning mechanism ensures the positioning and limiting of the rotation angle of the locking component, ensuring the flexibility of mold disassembly and assembly and the reliability of installation.

[0041] One specific application of this embodiment is as follows: Figure 1 and Figure 3 The left side shows the locked state of the mold 2 on the mold base 1. In this state, the positioning block 53 is located in the positioning groove 57, the locking pin 32 is offset from the clearance groove 34, and the ejector part 4 is in the reset state.

[0042] Disassembly of mold 2: While holding handle 54, press down on polygonal sleeve 52. Polygonal sleeve 52 moves downward outside polygonal rod 51, positioning spring 58 is compressed, positioning block 53 moves from positioning groove 57 to distance groove 56. At this time, turn handle 54 and drive rotating seat 33 to rotate synchronously. Rotating rotating seat 33 drives gear 41 to rotate. Gear 41 drives slide 42 to move towards one end of mold 2 through meshing with rack 43. At this time, ejection spring 45 is charged. When positioning block 53 rotates to the other end of distance groove 56, clearance groove 34 and locking pin 32 are concentric. The rebound force of ejection spring 45 after being charged drives ejection block 44 to move forward and causes mold 2 to move upward. At this time, locking pin 32 is squeezed into clearance groove 34 and 36 is compressed. Mold 2 is released upward from inside mold base 1. Then the staff takes out mold 2.

[0043] Installation of mold 2: Select a mold 2 of appropriate size and place it inside the mold base 1. At this time, press down on the mold 2. After the bottom of the mold 2 pushes the top block 44, the ejector spring 45 is compressed. The locking pin 32 is engaged with the annular groove 31 under the action of 36. At this time, hold the handle 54 and rotate it in the opposite direction. The ejector part 4 is reset. The clearance groove 34 is misaligned with the locking pin 32. The positioning block 53 is stuck in the positioning groove 57 under the action of the positioning spring 58, thus completing the locking after the mold 2 is installed.
