Description

Technical Field

[0001] This invention relates to the field of upsetting equipment for aero-engine forged blades, and particularly to a device and method for adjusting the position of the upsetting die punch. Background Technology

[0002] Flat forging is essentially a multi-directional die forging process. The forging is upset by a punch and two clamping dies when closed, and is mostly made from bar or rod stock. Its purpose is to create locally concentrated areas to prepare for pre-forging blade tenons or mounting plates.

[0003] During the machining process, the punch fixed on the male die holder impacts the female die to complete the upsetting. Before machining, the fixed position of the punch needs to be precisely adjusted to control the dimensions of the resulting tenon or mounting plate.

[0004] In existing technologies, the common method for adjusting the position of a punch is to add shims. However, this method has many drawbacks: First, the position of the punch is difficult to adjust quickly and over a wide range; Secondly, adding too many shims will cause the punch to be unstable, affecting forging accuracy and equipment safety; Therefore, there is an urgent need for an adjustment device that can combine rapid coarse adjustment with precise fine adjustment to adjust the position of the punch. Summary of the Invention

[0005] The main objective of this invention is to provide a device and method for adjusting the position of an upsetting die punch, which enables coarse adjustment of the punch position and precise adjustment in conjunction with traditional punch shims, thereby achieving adjustment of the upsetting punch position.

[0006] To achieve the above objectives, the present invention provides an adjusting device for the position of an upper forging die punch, comprising a male die seat, a wedge block, and an upper forging machine inclined body, all installed in the mounting groove of the upper forging machine punch slide. The upper forging machine inclined body is fixed within the mounting groove of the upper forging machine punch slide. The male die seat is slidably fitted with the mounting groove of the upper forging machine punch slide. A clamping mechanism is provided on the upper forging machine punch slide to clamp the male die seat when the position is adjusted. The wedge block is positioned between the upper forging machine inclined body and the male die seat. Between, and the right end face of the male die holder abuts against the left end plane of the wedge block; the right side face of the wedge block is set as a wedge surface inclined from the upper left to the lower right, and the wedge surface contacts and slides with the inclined surface of the upsetting machine body; a driving mechanism is provided between the wedge block and the upsetting machine body to drive the wedge block to move up and down; multiple punches are inserted at the left end of the male die holder, and a shim is sleeved on the insertion rod of the punch, and the shim is located between the left end face of the male die holder and the annular limiting platform of the punch.

[0007] Preferably, the tightening mechanism is a tightening screw screwed onto the slide block of the forging machine punch.

[0008] Preferably, the driving mechanism includes a driving screw; a square column is integrally formed on the top of the wedge block, and a screw mounting block is integrally formed on the right side of the square column, and the screw mounting block is located above the inclined body of the upsetting machine; the driving screw is vertically screwed onto the screw mounting block, and the lower end of the driving screw is rotatably connected to the top of the inclined body of the upsetting machine.

[0009] Preferably, the top of the drive screw is provided with a hexagonal head.

[0010] Preferably, a vertical post is welded to the top of the drive screw, and a cross handle is welded to the top of the post.

[0011] Preferably, a T-slot is provided at the top of the inclined body of the upsetting machine; a retaining connector is provided at the lower end of the drive screw, and the retaining connector is engaged in the T-slot.

[0012] Preferably, the gasket has different thickness specifications.

[0013] Preferably, grease is applied between the wedge-shaped surface of the wedge block and the inclined surface of the upsetting machine.

[0014] Preferably, the male mold base is provided with a set screw hole, and a set screw is screwed into the set screw hole for tightening the punch.

[0015] Secondly, the present invention proposes a method for adjusting the position of the punch in an upper forging die, employing the aforementioned adjusting device, comprising the following steps: First adjustment: Loosen the locking mechanism on the punch slider of the forging machine to release the locking of the male die seat. Operate the drive mechanism to drive the wedge block to move up and down. By cooperating the wedge surface of the wedge block with the inclined surface of the forging machine, the vertical movement of the wedge block is converted into a horizontal thrust or release on the male die seat. Then, manually apply a force to the right to the male die seat so that the male die seat is close to the wedge block. Then use the clamping mechanism to clamp and fix the male die seat, thus achieving a rough adjustment of the punch position. Second adjustment: Based on the precise position required for each punch, select a shim of appropriate thickness and fit it onto the insertion rod of the punch, then install the punch back into the male mold base.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: (1) Two-stage adjustment with high precision: The traditional single shim adjustment is decomposed into a two-step method of "wedge mechanism coarse adjustment + shim fine adjustment". The coarse adjustment mechanism quickly adjusts the position to be close to the target, and the fine adjustment mechanism (shim) performs the final calibration. The overall adjustment accuracy is much higher than that of the traditional method.

[0017] (2) Wide adjustment range and wide applicability: The wedge mechanism can realize a wide range of continuous movement of the male die seat, overcoming the problem of limited adjustment range when relying solely on shims, and can adapt to the needs of more specifications of forgings and punches.

[0018] (3) Easy to operate and efficient: Coarse adjustment can be easily completed by driving screws, eliminating the tedious process of repeatedly disassembling and assembling multiple gaskets, and greatly improving the efficiency of setting and mold changing.

[0019] (4) Stable structure and good rigidity: After the rough adjustment is completed, the male die seat is firmly locked by the clamping mechanism, and the right end face of the male die seat abuts against the left end plane of the wedge block, resulting in high overall rigidity. The number of shims required for fine adjustment is reduced, which reduces the risk of decreased contact rigidity and loosening caused by excessive shim stacking, and improves the stability of the forging process and the safety of the equipment.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0025] Combination Figure 1 and Figure 2 As shown, on one hand, a device for adjusting the position of an upper forging die punch includes a male die seat 1, a wedge block 2, and an upper forging machine inclined body 3 installed in the mounting groove of the upper forging machine punch slide. The upper forging machine inclined body 3 is fixed in the mounting groove of the upper forging machine punch slide by bolts or other fastening methods (not fully shown in the figure). The male die seat 1 is slidably engaged with the mounting groove of the upper forging machine punch slide. A clamping mechanism is provided on the upper forging machine punch slide to clamp the male die seat 1 in position and prevent movement during forging. The upper forging machine punch slide (not shown in the figure) is an existing structure on the upper forging machine and is conventional prior art, so it will not be described in detail here. The clamping mechanism is a clamping screw (not shown in the figure) screwed onto the upper forging machine punch slide. The clamping screw is also an existing structure on the upper forging machine, so it will not be described in detail here.

[0026] The wedge block 2 is disposed between the forging machine inclined body 3 and the male die seat 1, and the right end face of the male die seat 1 abuts against the left end plane of the wedge block 2; the right side face of the wedge block 2 is configured as a wedge-shaped surface inclined from the upper left to the lower right, and the wedge-shaped surface contacts and slides with the inclined surface of the forging machine inclined body 3; a driving mechanism is provided between the wedge block 2 and the forging machine inclined body 3, and by operating the driving mechanism, the wedge block 2 can be driven to move up and down in the vertical direction.

[0027] Multiple punches 4 are inserted into the left end of the male mold base 1. The tail of each punch 4 is provided with a connecting rod 4a, which is used to insert into the corresponding mounting hole of the male mold base 1. Washers 5 are fitted on the connecting rods 4a of the punches 4. These washers 5 are located between the left end face of the male mold base 1 and the annular limiting platform 4b of the punch 4 itself.

[0028] The working principle and adjustment process of the structure described above are as follows: Combination Figure 1 As shown, in actual use, the female die holder 9 is installed on the clamping slide of the forging machine, and the female die 10 is installed inside the female die holder 9. The female die holder 9 is positioned to the left of the male die holder 1, and the punch 4 on the male die holder 1 can punch into the corresponding punch hole of the female die 10 to forge the workpiece. When it is necessary to adjust the axial position of the punch, the adjustment process is as follows: First adjustment (coarse adjustment): When adjusting the punch position, first operate the drive mechanism to move wedge 2 up and down. Since the right wedge surface of wedge 2 engages with the inclined surface of the fixed forging machine's inclined body 3, when wedge 2 moves downwards, a gap will form between the left end face of wedge 2 and the right end face of the male die seat 1. Then, manually push the male die seat 1 to the right so that it rests against the left end of wedge 2 again, and then adjust the position until the male die seat is firmly in place. When wedge 2 moves upwards, it will generate a horizontal displacement component to the left under the action of the inclined surface. Since the right end face of the male die seat 1 rests against the left end plane of wedge 2, this horizontal displacement will push the entire male die seat 1, along with all the punches on it, to the left. Through this mechanism, a large-range, continuous, stepless coarse adjustment of the overall position of the male die seat 1 and all the punches is achieved. After adjusting to the appropriate range, use the clamping mechanism to firmly fix the male die seat 1.

[0029] Second adjustment (fine-tuning): Based on the first coarse adjustment, for each punch 4, according to its specific required extension amount, select shims 5 of different thicknesses and place them on the insertion rod 4a of the punch 4, and position them between the left end face of the male mold base 1 and the punch annular limiting platform 4b. By changing the shims 5 of different thicknesses, the extension amount of a single punch 4 can be finely adjusted. The combination of the two adjustments ensures that all punches can be precisely fixed in the optimal working position.

[0030] In this embodiment, the driving mechanism is used to drive the wedge block 2 to move up and down. Specifically, the driving mechanism includes a driving screw 6.

[0031] A square column 2a is integrally formed on the top of the wedge block 2. A screw mounting block 2b is integrally formed on the right side of the square column 2a, and this screw mounting block 2b is located above the forging machine inclined body 3. The drive screw 6 is vertically screwed into the threaded hole on the screw mounting block 2b. The lower end of the drive screw 6 forms a rotatable connection with the top of the forging machine inclined body 3. To achieve this rotatable connection, a specific solution is to provide a T-slot 3a on the top of the forging machine inclined body 3. A retaining clip 6b is provided at the lower end of the drive screw 6, and during assembly, the retaining clip 6b is inserted into the T-slot 3a. In this way, the drive screw 6 can rotate freely around its axis without coming out of the T-slot.

[0032] A hexagonal head 6a can be provided on the top of the drive screw 6 for operation with a wrench. To further optimize the user experience, a vertical rod 7 can be welded to the top of the drive screw 6, and a cross handle 8 can be welded to the top of the rod 7. By manually rotating the cross handle 8, the screw 6 can be driven to rotate more easily and quickly.

[0033] Multiple punches 4 are inserted into the left end of the male mold base 1. Each punch 4 has a cylindrical insertion rod 4a at its tail, which is precisely inserted into a corresponding mounting hole on the male mold base 1. An annular limiting platform 4b is provided on the punch 4 to limit the insertion depth. Washers 5 are fitted onto the insertion rod 4a of the punch 4. These washers 5 are sandwiched between the left end face of the male mold base 1 and the annular limiting platform 4b of the punch 4. Importantly, the washers 5 are available in various thicknesses (e.g., 1.0 mm, 1.5 mm, 2.0 mm, etc.) to allow for selection and combination according to precise dimensional requirements, achieving micron-level or higher precision fine-tuning.

[0034] To reduce wear between the wedge block 2 and the inclined body 3 of the upsetting machine, grease is applied between the wedge-shaped surface of the wedge block 2 and the inclined surface of the upsetting machine 3.

[0035] Combination Figure 1 As shown, a set screw hole 1a is provided on the male mold base 1, and a set screw is screwed into the set screw hole 1a to tighten the plug rod 4a of the punch 4.

[0036] Secondly, this embodiment provides a method for adjusting the position of the top forging die punch, using the aforementioned adjusting device, and includes the following steps: First adjustment: Loosen the locking mechanism on the punch slider of the forging machine to release the locking of the male die seat 1. Operate the drive mechanism to drive the wedge block 2 to move up and down. By cooperating the wedge surface of the wedge block 2 with the inclined surface of the forging machine inclined body 3, the vertical movement of the wedge block 2 is converted into a horizontal pushing force or release on the male die seat 1. Then, manually apply a force to the right to the male die seat 1 so that the male die seat 1 is close to the wedge block 2. Then use the clamping mechanism to clamp and fix the male die seat 1 to achieve a rough adjustment of the punch position. Second adjustment: Based on the precise position required for each punch 4, select a shim 5 of appropriate thickness and fit it onto the plug rod 4a of the punch, and then install the punch 4 back into the male mold base 1.

[0037] The above two-stage adjustment mechanism perfectly solves the various drawbacks of the traditional single shim adjustment method, providing reliable equipment support for the forging of high-precision aero-engine blades.
