Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a casting forging assembly and forming processing equipment. Background Technology

[0002] In the forging process of castings, the ingot blank is usually placed on the lower die, and then the upper die is used to press down to complete the forging.

[0003] However, for some molds where the center height is higher than the edge, or when the working surface of the mold has a certain tilt angle, the center of gravity of the ingot may be unstable after it is placed. After the operator uses a clamp to place the ingot in place, in the gap between the clamp and the upper mold before it touches the ingot, the ingot may slip or shift due to gravity or other reasons, and cannot be stably kept in the predetermined position in the center of the mold. This shift will cause uneven stress on the casting during the forging process, which will not only affect the molding quality, but may also produce scrap or even damage the mold.

[0004] There is a lack of effective solutions in the existing technology for reliably positioning the casting before the forging action begins and for automatically releasing the positioning during the forging process to avoid interference. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where ingots are prone to shifting on the mold, and to propose a casting forging assembly and forming processing equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A casting forging assembly includes a frame;

[0008] The slide block is provided with slide rails on both sides of the inner wall of the frame. The slide block is slidably disposed inside the frame via the slide rails. The same set of molds is installed on the bottom inner wall of the frame and the bottom of the slide block.

[0009] A hydraulic cylinder is installed on the top inner wall of the frame, and the end of the hydraulic cylinder's telescopic shaft is fixedly connected to the top of the slide.

[0010] The hydraulic cylinder drives the slide block to move up and down along the slide rail, thereby causing the upper mold to press towards or away from the lower mold, thus realizing the forging and forming of the casting.

[0011] A forming and processing equipment, including the aforementioned casting forging assembly, further includes:

[0012] Two limiting frames are located on both sides above the lower mold, and an integral connecting frame is fixedly installed on the side wall of the limiting frame;

[0013] Two limiting seats are located on opposite sides of the two connecting frames, and the lateral section of the limiting seats is used to laterally limit the connecting frames;

[0014] Two mounting brackets are set on both sides of the bottom of the slide. The vertical section of the mounting bracket is fixedly set at the bottom of the slide. The mounting bracket is sleeved on the outside of the connecting bracket. An inclined block is fixedly set at the top of the horizontal section of the mounting bracket. A guide block is fixedly set inside the connecting bracket. The bottom of the guide block is provided with an inclined surface that cooperates with the inclined block.

[0015] When the slide moves downward, the bottom surface of the slide abuts against the limiting seat and pushes it downward, causing the lateral section of the limiting seat to disengage from the connecting frame. The connecting frame and the limiting frame move laterally to remove the limiting effect on the casting.

[0016] When the slide returns to its upward position, the inclined surface of the inclined block engages with the inclined surface of the guide block, pushing the connecting frame and the limit frame to return to their horizontal position.

[0017] In one possible design, a limiting rod is fixedly provided on the side wall of the connecting frame and the bottom of the limiting seat, and the limiting rod slides through the interior of the frame. A spring is sleeved on the outer wall of the limiting rod to reset the limiting seat and the connecting frame.

[0018] In one possible design, the spring used to reset the connecting frame is a tension spring, and the spring used to reset the limiting seat is a compression spring.

[0019] In one possible design, the bottom inner wall of the rack has two recesses for use as channels for the downward movement of the corresponding mounting brackets.

[0020] In one possible design, a positioning block is fixedly provided on the side wall of the connecting frame to limit the reset position of the limiting seat.

[0021] In one possible design, the same guide telescopic rod is fixedly installed between the side wall of the limiting frame and the inner side wall of the frame on the same side, for guiding the lateral movement of the limiting frame.

[0022] In this application, during actual use, the operator first uses a clamp to place the casting on the top of the lower mold, between the two limiting frames, to ensure that it is in the middle position. Then, the hydraulic cylinder is controlled to drive the slide and the corresponding upper mold to move downward. When the upper mold presses down on the casting, the bottom surface of the slide also abuts against the top of the vertical section of the limiting seat. Then it continues to move downward. When the horizontal section of the limiting seat is pushed away from the side of the connecting frame, the casting will undergo slight deformation, and the connecting frame will be reset by the force of the tension spring, thereby driving the limiting frame to move laterally, thus separating it from the limiting of the casting and the mold. The connecting frame will then be located above the horizontal section of the limiting seat. Then, the forging operation can continue to be performed by pressing down.

[0023] When the drive slide is forged downwards, it will simultaneously move the mounting bracket downwards, causing the inclined block inside to disengage from the connecting bracket. After forging, when the slide is reset upwards, the mounting bracket and the inclined block reset synchronously. At this time, the operator removes the shaped casting using a fixture. When the slide rail is at the end of the reset process, the inclined surface of the inclined block will abut against one end of the inclined surface of the guide block. Continuing the reset will push the guide block to move laterally, thereby resetting the connecting bracket and the limiting bracket. After the slide is successfully reset, the connecting bracket and the limiting bracket will also move back to their original positions. During this period, the connecting bracket will first reset upwards via a compression spring until it abuts against the bottom of the connecting bracket. After the connecting bracket resets to its original position, it will also disengage from the upper part of the lateral section of the limiting bracket, allowing the limiting bracket to continue resetting via a compression spring. When the limiting bracket abuts against the positioning block, it resets to its original position.

[0024] In this utility model, the casting forging assembly, through the cooperation of the forging press mold, can place the heated ingot into the mold cavity of a fixed shape, apply pressure to fill the cavity, thereby obtaining a forging consistent with the mold cavity and achieving the effect of die forging;

[0025] In this utility model, the forming and processing equipment can achieve the lateral retraction of the limiting frame at the start of forging through a mechanical linkage structure, thereby avoiding interference of the limiting frame with the subsequent forging process and the working space of the mold, and ensuring the normal progress of the forging process.

[0026] In this invention, the automatically resetting limiting frame can position the casting from both sides before forging, effectively preventing the casting from slipping or shifting due to instability of the center of gravity after the fixture is removed and before the upper mold is pressed down, ensuring that the casting is always in the correct position in the center of the mold, thereby improving the forging quality.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] In one embodiment: Reference Figure 1 A casting forging assembly includes a frame 1, a slide block 2, and a hydraulic cylinder 4. Vertical slide rails 3 are fixedly installed on the inner walls of both sides of the frame 1. The slide block 2 is slidably connected to the inside of the frame 1 via the slide rails 3, allowing it to move up and down along the slide rails 3. An upper die 5 is fixedly installed at the bottom of the slide block 2, and a lower die 5 is fixedly installed on the bottom inner wall of the frame 1. The upper and lower dies 5 together form the forming cavity of the casting. The hydraulic cylinder 4 is fixed to the top inner wall of the frame 1 via a mounting base. Its piston rod extends downwards, with its end fixedly connected to the top of the slide block 2. By controlling the extension and retraction of the piston rod of the hydraulic cylinder 4, the slide block 2 and its upper die 5 can be driven to complete the pressing and resetting operations, achieving the effect of die forging.

[0036] Based on the forging assembly with the above-mentioned die forging effect, a forming and processing equipment is further disclosed. The equipment, based on the forging assembly, also includes components such as a limiting frame 10, a connecting frame 11, a limiting seat 6, a mounting frame 15, an inclined block 14, and a guide block 13, which are used to limit and constrain the placed ingot, thereby ensuring that it is in the middle position during forging.

[0037] refer to Figure 2-3 Two limiting frames 10 are laterally slidably mounted on both sides above the lower mold 5 via guide telescopic rods 9. One end of the guide telescopic rod 9 is connected to the limiting frame 10, and the other end is connected to the inner side wall of the frame 1, serving as a guide and stabilizer. An integrated connecting frame 11 is provided on the outer side of each limiting frame 10. Two limiting seats 6 are located on the opposite sides of the two connecting frames 11. Each limiting seat 6 is L-shaped, with its vertical section extending upward and its horizontal section located on the outer side of the connecting frame 11 in its initial position, thereby preventing the connecting frame 11 and its associated limiting frame 10 from moving outward.

[0038] Limiting rods 8 are fixedly connected to the side wall of the connecting frame 11 and the bottom of the limiting seat 6. The limiting rods 8 slide through the corresponding parts of the frame 1. The springs 7 sleeved on the limiting rods 8 provide a restoring force. Specifically, the springs 7 on the limiting rods 8 connected to the connecting frame 11 are tension springs, which always give the connecting frame 11 an outward pulling force. The springs 7 on the limiting rods 8 connected to the limiting seat 6 are compression springs, which always give the limiting seat 6 an upward pushing force.

[0039] refer to Figure 4 There are two mounting brackets 15, which are fixed to the two sides of the bottom of the slide block 2 by bolts and move synchronously with the slide block 2. The mounting bracket 15 is U-shaped, with the upper end of its vertical section fixed to the slide block 2 and its horizontal section extending downward and fitting around the outside of the connecting bracket 11. An inclined block 14 is fixed at the top of the horizontal section of the mounting bracket 15. Correspondingly, a guide block 13 extending along the length of the connecting bracket 11 is fixed inside the connecting bracket 11. The bottom of the guide block 13 is machined with an inclined surface that matches the inclined surface of the inclined block 14. A notch 12 is opened at the bottom of the frame 1 to serve as a channel for the mounting bracket 15 to move downward.

[0040] During operation, the operator first uses a clamp to place the casting on top of the lower mold 5 and position it between two limit frames 10, which ensure that the casting is centered.

[0041] When the equipment is started, the hydraulic cylinder 4 drives the slide 2 and the upper mold 5 to move downward. As the lower mold 5 contacts the casting, the bottom surface of the slide 2 also abuts against the top of the vertical section of the limit seat 6, and pushes the limit seat 6 to move downward against the force of the compression spring. When the horizontal section of the limit seat 6 moves down to the side of the connecting frame 11, the connecting frame 11 and the limit frame 10 lose their outer constraints and move laterally outward under the tension of the tension spring, thereby removing the area between the two sides of the casting and the upper and lower molds. At this time, the casting undergoes slight deformation. Then, the upper mold 5 continues to press down to complete the forging of the casting.

[0042] After forging, the hydraulic cylinder 4 drives the slide 2 to move upward and reset. The slide 2 drives the mounting frame 15 and the inclined block 14 to move upward together. At the end of the reset stroke, the inclined surface of the inclined block 14 contacts the inclined surface of the guide block 13. As it continues to move upward, the inclined surface pushes the guide block 13 and the connecting frame 11 fixed thereto to move inward laterally, overcoming the tension spring force, so that the limit frame 10 returns to the initial positioning position. During this process, the limit seat 6 will be reset by the force of the compression spring, so that it moves to the bottom of the connecting frame 11. After the connecting frame 11 is reset, it will be removed from the upper part of the horizontal section of the limit seat 6, so that it is reset upward under the action of the compression spring until the bottom of its horizontal section touches the positioning block 17 and returns to the initial limit state. At this time, the equipment is completely reset and the next work cycle can be carried out.

[0043] This application can be used in the field of casting processing, or in other fields applicable to this application.

[0044] In another embodiment: Reference Figure 5-6 A forming and processing equipment is applied in the field of casting processing. To protect the mechanism and optimize the appearance, protective shells 16 are installed on both sides of the bottom of the slide 2 to cover moving parts such as the limit seat 6 and the mounting bracket 15 on the same side. A channel for the protective shells 16 to move is opened at the corresponding position at the bottom of the frame 1. In addition, a positioning block 17 is installed on the side wall of the connecting frame 11 to limit the upper limit position of the limit seat 6 under the action of the compression spring.

[0045] The limiting seat 6 can be set to an L-shape, or to improve stability during movement, it can be set to a U-shape, and the corresponding limiting rod 8 and spring 7 are set to two, and are located in the vertical section.

[0046] Furthermore, the limiting bracket 10 can be a horizontal long strip bracket or an L-shaped bracket, thereby further increasing the limiting effect on the ingot.

[0047] However, as is well known to those skilled in the art, the working principle and wiring method of the hydraulic cylinder 4 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0048] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
