Description

Technical Field

[0001] This utility model belongs to the field of alloy pressing and forming, and specifically relates to an alloy pressing and forming equipment. Background Technology

[0002] Alloy pressing equipment is a specialized device used to press alloy powder or granules into blanks with specific shapes, sizes, and densities under pressure. This equipment plays a crucial role in the production of alloy products and is widely used in aerospace, automotive manufacturing, electronics, machining, and many other fields, capable of producing alloy parts blanks of various complex shapes and high performance.

[0003] It mainly consists of a press, a mold, and a pressure control system. The press provides the pressing power; common types include hydraulic presses and mechanical presses. Hydraulic presses transmit power through the pressure of hydraulic oil, offering advantages such as high pressure and stable pressing. Mechanical presses utilize mechanical transmission mechanisms to generate pressure, offering high speed and efficiency. The mold is a key component determining the shape of the preform, designed into various shapes according to different product requirements. The pressure control system precisely controls parameters such as pressing pressure, loading speed, and holding time to ensure the quality of the preform.

[0004] When the equipment starts to perform the pressing operation, alloy powder overflows from the top of the mold. This overflowing alloy powder not only scatters on the surface of the lower mold base, but also adheres to the surface of the blank when the pressing process is completed and the material pushing stage begins. This makes the surface of the blank no longer smooth and even. The reduction in the smoothness of the blank surface will lead to poor product quality after sintering, resulting in a decrease in the product qualification rate.

[0005] In view of this, the present invention provides an alloy pressing and forming equipment to solve the problem of overflowing alloy powder adhering to the surface of the blank, which leads to a decrease in the product qualification rate. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an alloy pressing and forming equipment, comprising:

[0007] The blank forming assembly includes a device body located at the bottom for blank pressing, a lifting rod installed on the top of the device body and extending into the interior, an upper die head connected to the movable end of the lifting rod, a mounting plate installed inside the device body, and a lower die base installed on the upper surface of the mounting plate and located directly below the upper die head.

[0008] The waste material handling assembly includes a bracket connected to the surface of the mounting plate, guide parts symmetrically arranged on both sides of the upper surface of the bracket, a waste material handling part connected to the upper surfaces of the two guide parts and handling the waste material during pressing, and a second telescopic rod connected to the side surface of the waste material handling part and installed on the surface of the bracket.

[0009] The compaction assembly includes a compaction section connected to the inner wall of a support and a drive section mounted on the side surface of the compaction section.

[0010] As a preferred embodiment of the alloy blank forming equipment of this utility model, the guide part includes a guide rail connected to the upper surface of the support and a guide sleeve sleeved on the surface of the guide rail and adapted to it.

[0011] As a preferred embodiment of the alloy blank forming equipment of this utility model, the overflow treatment unit includes a movable frame connected to the upper surface of the guide sleeve, a first telescopic rod installed on the side surface of the movable frame, a side lug connected to the movable end of the first telescopic rod, and a limiting semi-ring connected to the upper surface of the side lug.

[0012] In a preferred embodiment of the alloy pressing forming equipment of this utility model, the first telescopic rod, the side lug, and the limiting half ring are symmetrically arranged on both sides of the movable frame. The inner wall of the limiting half ring is set as an inclined surface, and the central axis of the ring formed by the combination of the limiting half rings coincides with the central axis of the upper die head.

[0013] As a preferred embodiment of the alloy blank forming equipment of this utility model, the rolling section includes a feeding trough connected to the inner wall of the support, a first rolling roller disposed on the inner wall of the feeding trough, a second rolling roller disposed on the inner wall of the feeding trough, and bearing rings respectively connected to the two ends of the first rolling roller and the second rolling roller and fitted onto the side surface of the feeding trough.

[0014] In a preferred embodiment of the alloy pressing forming equipment of this utility model, the vertical distance between the first pressing roller and the inner wall of the feeding trough is less than that between the second pressing roller and the inner wall of the feeding trough, and the inner wall of the feeding trough is inclined.

[0015] As a preferred embodiment of the alloy pressing forming equipment of this utility model, the driving unit is connected to a drive motor at the end of the second pressing roller, pulleys respectively connected to the end surfaces of the second pressing roller and the first pressing roller, and belt rings sleeved on the surfaces of the two pulleys.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, when alloy powder overflows, it falls onto the inclined surface inside the limiting semi-ring. During the pressing process, the overflowing alloy powder can be compacted. Then, the lifting rod drives the upper die head to move upward and the second telescopic rod moves. When the second telescopic rod retracts, it drives the compacted alloy powder to move laterally through the overflow treatment part. When the overflow treatment part drives the compacted alloy powder to the upper part of the feeding groove, the first telescopic rod drives the two limiting semi-rings to move laterally in a direction away from each other through the side ears. At this time, the compacted alloy powder falls into the feeding groove. This can comprehensively treat the overflowing metal powder, thereby preventing the powdery metal powder from adhering to the surface of the blank during demolding and affecting the quality of the finished product.

[0018] This invention enables the second and first rolling rollers to rotate simultaneously via a drive unit. The rotation of the second and first rolling rollers can crush the alloy powder that has fallen into the feeding trough and been compacted, facilitating the subsequent reuse of the alloy powder material and reducing the waste of raw materials.

Detailed Implementation

[0030] 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 protection scope of the present utility model.

[0031] Example 1

[0032] This utility model relates to an alloy pressing and forming equipment, such as... Figures 1-7 As shown, it includes:

[0033] The blank pressing assembly 100 includes a device body 101 for blank pressing located at the bottom, a lifting rod 102 installed on the top of the device body 101 and extending into the interior, an upper die head 103 connected to the movable end of the lifting rod 102, a mounting plate 104 installed inside the device body 101, and a lower die base 105 installed on the upper surface of the mounting plate 104 and located directly below the upper die head 103.

[0034] The waste material handling assembly 200 includes a bracket 201 connected to the surface of the mounting plate 104, guide parts 202 symmetrically arranged on both sides of the upper surface of the bracket 201, a waste material handling part 203 connected to the upper surfaces of the two guide parts 202 and handling the waste material during pressing, and a second telescopic rod 204 connected to the side surface of the waste material handling part 203 and installed on the surface of the bracket 201.

[0035] The guide section 202 includes a guide rail 202a connected to the upper surface of the bracket 201 and a guide sleeve 202b fitted onto and adapted to the surface of the guide rail 202a. When the movable frame 203a is subjected to a force, it can drive the guide sleeve 202b to slide on the surface of the guide rail 202a, thus ensuring the stability of the movable frame 203a during operation.

[0036] Furthermore, the overflow handling unit 203 includes a movable frame 203a connected to the upper surface of the guide sleeve 202b, a first telescopic rod 203b mounted on the side surface of the movable frame 203a, a side lug 203c connected to the movable end of the first telescopic rod 203b, and a limiting semi-ring 203d connected to the upper surface of the side lug 203c. When the first telescopic rod 203b is in operation, it can drive the side lug 203c to move laterally, and the lateral movement of the side lug 203c can drive the limiting semi-ring 203d to move laterally, thereby adjusting its position.

[0037] Furthermore, the first telescopic rod 203b, the side ear 203c, and the limiting half ring 203d are symmetrically arranged on both sides of the movable frame 203a. The inner wall of the limiting half ring 203d is set as an inclined surface, and the central axis of the ring formed by the limiting half ring 203d coincides with the central axis of the upper mold head 103.

[0038] In use, firstly, the alloy powder is placed inside the core of the lower die holder 105. Then, the lifting rod 102 is controlled to drive the upper die head 103 downward. When the upper die head 103 moves into the core of the lower die holder 105, the alloy powder will be gradually compressed during the extrusion process. When the alloy powder overflows, it will fall onto the inclined surface inside the limiting half-ring 203d. Then, the limiting half-ring 203d is controlled to press the alloy powder into a compact. During the pressing process, the overflowing alloy powder can be compacted. Then, the lifting rod 102 is controlled to drive the upper die head 103 downward. The upper die head 103 moves upward, and then the second telescopic rod 204 is controlled to retract. When the second telescopic rod 204 retracts, it can drive the compacted alloy powder to move laterally through the overflow treatment part 203. When the overflow treatment part 203 drives the compacted alloy powder to the upper part of the feeding groove 301a, the first telescopic rod 203b can be controlled to drive the two limiting half rings 203d to move laterally in a direction away from each other through the side ear 203c. At this time, the compacted alloy powder falls into the feeding groove 301a.

[0039] Then, the bottom plate can be pushed upward by the telescopic rod of the lower mold base 105 to push out the blank, thereby realizing the demolding of the blank.

[0040] Example 2

[0041] like Figures 1-9 The second embodiment of the present invention is shown, which differs from the first embodiment described above only in that: the rolling assembly 300 includes a rolling part 301 connected to the inner wall of the support 201 and a driving part 302 installed on the side surface of the rolling part 301.

[0042] The compaction unit 301 includes a feeding trough 301a connected to the inner wall of the support 201, a first compaction roller 301b disposed on the inner wall of the feeding trough 301a, a second compaction roller 301c disposed on the inner wall of the feeding trough 301a, and a bearing ring 301d respectively connected to the two ends of the first compaction roller 301b and the second compaction roller 301c and fitted onto the side surface of the feeding trough 301a. By rotating the first compaction roller 301b and the second compaction roller 301c inside the bearing ring 301d, the compacted alloy powder can be compacted, thereby achieving the pulverization of the compacted alloy powder and facilitating its recycling.

[0043] Furthermore, the vertical distance between the first rolling roller 301b and the inner wall of the feeding trough 301a is less than the vertical distance between the second rolling roller 301c and the inner wall of the feeding trough 301a, and the inner wall of the feeding trough 301a is inclined. By setting the second rolling roller 301c and the first rolling roller 301b at different heights, the second rolling roller 301c can perform initial coarse rolling on the compacted alloy powder, while the first rolling roller 301b performs further fine rolling.

[0044] Furthermore, the drive unit 302 is connected to a drive motor 302a at the end of the second roller 301c, pulleys 302b connected to the end surfaces of the second roller 301c and the first roller 301b respectively, and belt rings 302c sleeved on the surfaces of the two pulleys 302b. When the second roller 301c rotates, it can drive the pulleys 302b connected to its end to rotate. When the pulleys 302b rotate, they can drive the first roller 301b to rotate through the belt rings 302c and the other pulley 302b, thereby realizing the linkage between the second roller 301c and the first roller 301b.

[0045] In use, when the drive motor 302a is running, it can drive the second crushing roller 301c to rotate. When the second crushing roller 301c rotates, it can drive the first crushing roller 301b to rotate inside the bearing ring 301d through the pulley 302b and belt ring 302c. In this way, the alloy powder that has fallen into the feeding trough 301a and is compacted can be crushed by the rotation of the second crushing roller 301c and the first crushing roller 301b, which is convenient for subsequent reuse.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
