Description

Technical Field

[0001] This utility model relates to the field of metal powder injection molding technology, and in particular to a sintering furnace material rack guiding and positioning device. Background Technology

[0002] Currently, the material plates for sintering furnaces are mostly handled manually during transfer. When loading, the material plates are removed from the rack (see reference). Figure 29 The material is pulled out from the sintering furnace (as shown), then manually transported to the furnace opening and pushed into the placement slot of the sintering furnace's sealing box. During unloading, the material plate is pulled out of the sintering furnace's sealing box and manually transported to the material rack. However, lighter material plates can be moved by one person, while heavier ones require two people, which is time-consuming and labor-intensive. Furthermore, when the sintering furnace is large, the top layers of the sealing box are quite high, making it difficult to manually lift the material plate and align it with the insertion opening. This can easily cause the material plate to bump into the sealing box, or even cause the processed material to fall and break. During unloading from the sintering furnace, the material plate temperature must be allowed to drop to a temperature that is touchable before handling can begin. The material plate cools slowly inside the sintering furnace's sealing box, resulting in excessively long waiting times and low production efficiency.

[0003] If the material rack is modified so that the height of the material rack's channel opening matches the opening of the sintering furnace's sealing box, and the height and width of the material rack's layers match the sintering furnace's sealing box, and the material rack and sintering furnace's sealing box are aligned by moving the support bracket, the material plates in the material rack can be pushed into the sintering furnace's sealing box using tooling during loading, and the material plates in the sintering furnace's sealing box can be pulled into the material rack using tooling during unloading. This can effectively solve the problem of slow manual handling of material plates piece by piece. Using tooling can also shorten the unloading time when the material plate temperature is high. However, in actual operation, it was found that due to large manufacturing errors in the sintering furnace, especially welding deformation and low manufacturing precision, coupled with uneven ground, the dimensions of each piece of equipment were inconsistent after assembly. For example, the height of the sealing box of the sintering furnace from the ground was inconsistent, and the width of the furnace legs was inconsistent. It was very difficult to align the slots of each layer of material plate of the moving support with the slots of each layer of the sealing box in the vertical and horizontal directions. It was also very difficult to achieve one moving support to feed multiple sintering furnaces. In some cases, the material plates of some sintering furnaces could not be pushed in and pulled out by the material rack. Utility Model Content

[0019] 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 analyzed and obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this invention is to provide a sintering furnace material rack guiding and positioning device to solve the problems existing in the prior art. Through the cooperation of guide rails and pulleys, the channel opening of the material rack can be aligned left and right with the opening of the sealing box inside the sintering furnace. By driving the guide rails to rise and fall through the lifting mechanism, the front wheels of the moving support of the material rack can be raised, so that the channel opening of the material rack is aligned with the opening of the sealing box in height. This avoids the situation where the height of the channel opening of the material rack and the opening of the sealing box cannot be consistent due to the different heights of different sintering furnaces.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 29 As shown, this embodiment provides a sintering furnace material rack guiding and positioning device. The sintering furnace material rack guiding and positioning device 4 is divided into a furnace-side mounting part and a material rack-side mounting part from the installation position. The furnace-side mounting part is installed on the furnace body support 101 of the sintering furnace 1. The material rack-side mounting part is installed on the movable support 201 of the material rack 2. Specifically, the sintering furnace material rack guiding and positioning device 4 includes a guide rail 401 and a pulley 402.

[0023] The guide rail 401 is mounted on the furnace body support 101 of the sintering furnace 1. The guide rail 401 can move up and down via a lifting mechanism; therefore, both the guide rail 401 and the lifting mechanism are part of the furnace-side installation. The guide rail 401 guides and supports the pulley 402. The pulley 402 is mounted on the movable support 201 of the material rack 2; therefore, the pulley 402 is part of the material rack-side installation. The opening of the placement channel of the material rack 2 can be brought close to the opening of the sealed box 103 inside the sintering furnace 1 by the movement of the movable support 201. The pulley 402 can slide onto the guide rail 401 as the opening of the material rack 2 approaches the opening of the sealed box 103. The placement channel of the material rack 2 is provided with multi-layer material plate slots 202. The number and position of the multi-layer material plate slots 202 are matched with the placement slots 102 inside the sealed box 103 of the sintering furnace 1. Typically, the sealed box 103 is a rectangular box; therefore, the placement channel of the material rack 2 is a rectangular channel.

[0024] Working principle: When the opening of the material rack 2 is brought close to the opening of the sealed box 103 of the sintering furnace 1, the pulley 402 slides onto the guide rail 401, ensuring that the opening of the material rack 2 is aligned horizontally with the opening of the sealed box 103 of the sintering furnace 1. If it is found that the opening of the material rack 2 is lower than the opening of the sealed box 103 of the sintering furnace 1, that is, each layer of placement slot 102 in the sealed box 103 is lower than each layer of material plate slot 202 of the material rack 2, then the height of the guide rail 401 can be raised by the lifting mechanism according to the height difference between the opening of the sealed box 103 of the sintering furnace 1 and the opening of the material rack 2. This will raise the pulley 402, thereby raising the material rack 2 and adjusting the height of the opening of the material rack 2 to compensate for the height difference. To avoid the problem that the opening of the material rack 2 is higher than the opening of the sealing box 103 of the sintering furnace 1 and cannot be adjusted, the initial height of the opening of the material rack 2 can be set low in advance, that is, lower than the opening of the sealing box 103 of any sintering furnace 1.

[0025] In one embodiment, there are two guide rails 401 and two pulleys 402. Preferably, the furnace body support 101 of the sintering furnace 1 consists of four legs, with the rear two legs located below the tail of the sintering furnace 1 and the front two legs located below the furnace opening of the sintering furnace 1. The two guide rails 401 are respectively disposed on the two front legs. The two pulleys 402 are spaced apart at the front end of the movable support 201, located in front of the passage opening of the material rack 2, so that the pulleys 402 slide onto the guide rails 401 before the passage opening of the material rack 2 enters the furnace opening of the sintering furnace 1.

[0026] In one embodiment, the lifting mechanism includes a limiting plate 403, a lifting seat 404, a vertical adjustment screw 405, and a first locking screw 406. The limiting plate 403 is fixedly connected to the furnace body support 101, and both the lifting seat 404 and the limiting plate 403 are threadedly connected to the vertical adjustment screw 405. The vertical adjustment screw 405 is vertically positioned, and the lifting seat 404 has a vertically positioned vertical bar hole 407. The first locking screw 406 passes through the vertical bar hole 407 and is threadedly connected to the furnace body support 101. The first locking screw 406 is horizontally positioned, and the guide rail 401 is mounted on the lifting seat 404. The limiting plate 403 may be located above the lifting seat 404, as shown in the reference. Figure 2 , Figure 3 , Figure 7 as well as Figure 16 As shown. The limiting plate 403 can also be located below the lifting seat 404, see reference. Figure 19 and Figure 26 As shown, etc.

[0027] Working principle: First, loosen the first locking screw 406 by rotating it, so that the lifting seat 404 and the furnace body support 101 can move relative to each other. Then, rotate the vertical adjustment screw 405 to drive the lifting seat 404 to rise or fall, which in turn drives the guide rail 401 to rise or fall. At this time, the position between the first locking screw 406 and the vertical bar hole 407 changes. After the adjustment is completed, tighten the first locking screw 406 to press the lifting seat 404 onto the furnace body support 101, thus completing the lifting adjustment of the guide rail 401.

[0028] In one embodiment, a locking and positioning mechanism is also included, comprising a limit adjustment screw 410, a rotary cylinder 408, and a pulley shaft 411. The pulley shaft 411 is horizontally mounted on the movable bracket 201, and the pulley 402 is mounted on the pulley shaft 411; therefore, the pulley shaft 411 in the locking and positioning mechanism belongs to the rack-side mounting portion. The axial direction of the pulley shaft 411 is parallel to the axle direction of the pulley 402. The rotary cylinder 408 is horizontally mounted on the lifting seat 404; therefore, the rotary cylinder 408 in the locking and positioning mechanism belongs to the furnace-side mounting portion. The rotation axis of the rotary cylinder 408 is parallel to the extension direction of the guide rail 401. A limit rod 412 is fixed on the rotation axis of the rotary cylinder 408. Rotation of the rotation axis of the rotary cylinder 408 can drive the limit rod 412 to rotate upwards to a vertical state or downwards to a horizontal state. The rotary cylinder 408 is mounted on the lifting seat 404 via a cylinder seat 409. A limit adjustment screw 410 is threaded onto the cylinder seat 409. The limit adjustment screw 410 is horizontally positioned, and its axis is parallel to the plane extending from the guide rail 401. The limit adjustment screw 410 is located on the forward path of the pulley shaft 411, thus limiting its forward movement. Rotating the limit adjustment screw 410 adjusts the maximum forward position of the pulley shaft 411. When the passageway of the material rack 2 is close to the furnace opening of the sintering furnace 1, the limit rod 412 can be rotated upwards to a vertical position. The pulley shaft 411 is limited by the limit adjustment screw 410. Rotating the limit rod 412 upwards and then backwards presses the pulley shaft 411 against the limit adjustment screw 410. (Reference) Figure 14 and Figure 17 , Figure 26 and Figure 27 As shown.

[0029] In one embodiment, the guide rail 401 is adjusted in a horizontal direction via a lateral movement mechanism. This horizontal direction is perpendicular to the extension direction of the guide rail 401, ensuring that the central axis of the guide rail 401 precisely aligns with the center line of the pulley 402's surface when the passage opening of the material rack 2 is aligned horizontally with the opening of the sealing box 103. This allows the pulley 402 to smoothly slide onto the guide rail 401. The lateral movement mechanism is part of the furnace-side mounting component.

[0030] In one embodiment, the traversing mechanism includes a traversing plate 413, a traversing adjustment screw 414, and a second locking screw 415. The traversing plate 413 is horizontally mounted on the lifting seat 404, and has a horizontally positioned horizontal bar hole 416, the extension direction of which is perpendicular to the extension direction of the guide rail 401. The second locking screw 415 passes through the horizontal bar hole 416 and is threaded to the top of the lifting seat 404; the second locking screw 415 is vertically positioned. An adjusting plate 417 is provided at the bottom of the traversing plate 413, and both the adjusting plate 417 and the lifting seat 404 are threadedly connected to the traversing adjustment screw 414. The traversing adjustment screw 414 is horizontally positioned, and its axis is parallel to the extension direction of the horizontal bar hole 416. The guide rail 401 is mounted on the traversing plate 413.

[0031] Working principle: First, rotate and loosen the second locking screw 415 so that the transverse plate 413 and the lifting seat 404 can move relative to each other along the horizontal bar hole 416. Then, rotate the horizontal adjustment screw 414 to drive the transverse plate 413 to move along the width direction of the sintering furnace 1, and then drive the guide rail 401 to move along the width direction of the sintering furnace 1. At this time, the position between the second locking screw 415 and the horizontal bar hole 416 changes. After the adjustment is completed, tighten the second locking screw 415 to press the transverse plate 413 onto the lifting seat 404, thus completing the lateral adjustment of the guide rail 401.

[0032] In one embodiment, an angle adjustment mechanism is also included, which is used to adjust the tilt angle of the guide rail 401. The angle adjustment mechanism is part of the furnace-side mounting section. The angle adjustment mechanism includes a countersunk screw 418, an angle adjustment screw 419, a countersunk through hole 420, and an adjusting screw hole 421. The countersunk through hole 420 and the adjusting screw hole 421 are both provided on the guide rail 401, and multiple countersunk through holes 420 and adjusting screw holes 421 are arranged at intervals along the extension direction of the guide rail 401, with at least two countersunk through holes 420 and two adjusting screw holes 421. The angle adjustment screw 419 is threaded onto the adjusting screw hole 421, and the countersunk screw 418 passes through the countersunk through hole 420 and is threaded onto the transverse plate 413. The countersunk screw 418 is vertically arranged, and the countersunk through hole 420 has a radial clearance with the countersunk screw 418, allowing relative movement between the countersunk through hole 420 and the countersunk screw 418. The countersunk head of the countersunk screw 418 is located within the countersunk hole of the countersunk through hole 420, and the diameter of the countersunk head of the countersunk screw 418 is larger than the diameter of the through hole 420. By rotating the adjusting screws 419 at different positions, the guide rail 401 can be raised at corresponding positions, thus adjusting the tilt angle of the guide rail 401. (Reference) Figure 8 and Figure 9 As shown.

[0033] In one embodiment, a transverse sliding plate 413 extends from the receiving end of the guide rail 401 to better adjust the tilt angle of the guide rail 401. (See reference) Figure 8 and Figure 9 As shown.

[0034] In one embodiment, the guide rail 401 and pulley 402 are coupled in two ways.

[0035] One of the references Figures 1 to 17 As shown: Guide rail 401 is a round rod guide rail, pulley 402 is a V-shaped pulley, and the receiving end of the round rod guide rail that receives the V-shaped pulley is provided with a conical head 423. The receiving end is the end through which the V-shaped pulley slides in and out. The conical head 423 is designed to facilitate the sliding of pulley 402 into guide rail 401.

[0036] Another reference Figures 18 to 27 As shown: Guide rail 401 includes a horizontal plate 424 and a vertical plate 425. The horizontal plate 424 is inclinedly mounted on the lifting seat 404. The horizontal plate 424 cooperates with the pulley 402 to lift the front wheel of the movable support 201. The vertical plate 425 is fixedly connected to the horizontal plate 424. A guide wheel seat 427 is mounted on the pulley shaft 411, and a guide wheel 428 is provided on the guide wheel seat 427. The axle of the guide wheel 428 is vertically arranged. The guide wheel 428 cooperates with the vertical plate 425 to position the material rack 2 left and right. The end of the vertical plate 425 facing the pulley 402 is bent outward to form a bent section 426. The bent sections 426 of the two guide rails 401 form a flared mouth, making the guidance of the guide wheel 428 smoother. The guide wheel seat 427 is provided with an elongated hole 429 extending along the axle direction of the pulley 402, and a third locking screw 430 is provided on the elongated hole 429 that is threadedly connected to the pulley shaft 411.

[0037] In one embodiment, a telescopic rod 422 is also included. The telescopic rod 422 is installed at the rear end of the movable support 201, with its telescopic end facing downwards. To address the issue of large height differences between different sintering furnaces 1, resulting in some sintering furnaces 1 having a large lifting distance for the front wheels of the movable support 201, causing the material rack 2 to tilt excessively and preventing the material plate 3 from being smoothly inserted into the sealing box 103, the telescopic rod 422 can be extended or retracted to raise the rear end of the material rack 2, making the material rack 2 horizontal overall. The telescopic rod 422 can be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod.

[0038] Specifically, when the material rack 2 is aligned with the sealing box 103 of the sintering furnace 1, it becomes uneven, with a certain tilt angle between the front and rear ends. The telescopic rod 422, through the control system, raises the rear end of the material rack 2 to the same level as the front end, facilitating smooth material feeding and discharging of the material plate 3. The height of each sintering furnace 1 is adjusted point-to-point, such as button one corresponding to the first sintering furnace 1, button two corresponding to the second sintering furnace 1. Height adjustment can also be performed by clicking the corresponding sintering furnace 1 number on the touchscreen. The control system has a height memory function; once adjusted for each sintering furnace 1 the first time, no further adjustments are needed, which is quite convenient.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
