Description

Technical Field

[0001] This utility model belongs to the field of target material preparation, and specifically relates to a blank demolding device for rotating target material. Background Technology

[0002] The forming of rotating target materials typically involves pre-filling a mold consisting of a rigid metal core and an elastic rubber sleeve with a predetermined amount of powder. The mold is then sealed and placed in a cold isostatic press for high-pressure forming. After removal, the blank is allowed to stand until the internal stress in the blank is released before removal. During blank removal, the elastic rubber sleeve is usually removed first, and then the blank, which is fitted onto the rigid core, is carefully removed manually to achieve demolding. However, this method is prone to uneven force, bumps, and scratches during demolding, leading to defects, cracks, or even damage to the target blank. Therefore, a device for demolding rotating target blanks is needed to improve demolding efficiency and reduce the probability of blank damage. Utility Model Content

[0003] The purpose of this invention is to provide a blank demolding device for rotating target material. This device can ensure that the blank demolding is stable and safe, and avoid the possible damage or even complete destruction of the blank due to bumps, scratches, etc. during the demolding process. This improves the efficiency of blank demolding and reduces the probability of blank damage.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a blank demolding device for rotating target material, including a base, two parallel and spaced tracks are provided on the upper surface of the base, and a support body is provided on the outer side of each track, with the support body perpendicular to the upper surface of the base.

[0005] The support platform includes an outer lifting platform and an inner sliding platform. The opposite sides of the sliding platform are slidably supported on the support surface inside the lifting platform, and the platform surface of the sliding platform is flush with the platform surface of the lifting platform. The lower surface of the sliding platform is provided with rollers that can roll along the track. One side of the lifting platform has an opening for the sliding platform to slide out of the lifting platform along the support surface. The sliding direction of the sliding platform on the lifting platform is the same as the movement direction of the sliding platform along the track.

[0006] A lifting mechanism is mounted on the base and connected to the lifting platform;

[0007] The fixing component includes a transverse support and a fixing ring. The fixing ring includes two semicircular rings. The outer surface of each semicircular ring is fixed to one end of the transverse support, and the other end of the transverse support is fixed to the support body on the same side. The ends of the two semicircular rings are connected by adjusting bolts.

[0008] Furthermore, the inner side of the fixing ring is provided with a flexible material layer that can contact the surface of the blank.

[0009] Furthermore, multiple fixing components are provided and arranged vertically at intervals.

[0010] Optionally, the support body can be a cylindrical support column.

[0011] In one embodiment, the lifting mechanism consists of a lead screw and a lead screw drive assembly. Four lead screws are provided and distributed at the four corners of the lifting platform. The lower end of each lead screw is rotatably connected to the base, and the upper end of the lead screw is threadedly connected to the lifting platform. The lead screw drive assembly is used to drive the four lead screws to rotate, thereby realizing the lifting of the carrying platform.

[0012] Furthermore, the lead screw drive assembly includes a power mechanism and a transmission mechanism. The power mechanism is mounted on the base, and the transmission mechanism is connected to the motor and the four lead screws. The power mechanism is a motor or a hand crank.

[0013] Alternatively, the transmission mechanism is a chain drive mechanism, including a main drive chain and a side drive chain. The main drive chain is used to connect the motor and two lead screws on both sides of the track and close to the motor. The side drive chain is used to connect two lead screws located on the same side outside the track.

[0014] As another option, the transmission mechanism is a synchronous belt transmission mechanism, which includes a main transmission synchronous belt and a side transmission synchronous belt; the main transmission synchronous belt is used to connect the motor and two lead screws on both sides of the track and close to the motor, and the side transmission synchronous belt is used to connect two lead screws located on the same side outside the track.

[0015] As another option, the transmission mechanism is a rotating shaft and a bevel gear set disposed between the rotating shaft and the lead screw. The motor is a dual-output motor, which connects two rotating shafts. The shaft end of each rotating shaft is connected to the adjacent lead screw through a bevel gear set. The two lead screws located on the same side outside the track are connected through another rotating shaft and a bevel gear set at the shaft end.

[0016] As another embodiment, the lifting mechanism is a scissor lift mechanism, a traction lifting mechanism, or a hydraulic lifting mechanism.

[0017] The beneficial effects of this utility model are: 1. This utility model has a simple and reliable structure, which ensures that the demolding of the blank can be carried out smoothly and safely, and avoids the possibility of damage or even complete destruction of the blank caused by bumps and scratches during the demolding process.

[0018] 2. This utility model can use an electrically driven lifting support platform to demold the blank, which greatly improves the demolding efficiency of the target blank, and the process can be completed by only 1 to 2 people.

[0019] 3. When it is impossible to use a motor to drive the lifting of the load-bearing platform, this utility model can also be driven by hand, which further improves the applicability of the device.

[0020] 4. In this utility model, multiple fixing components can be set according to the length of the target material, so that the device can support demolding of targets of any diameter and weight. For ultra-long and ultra-heavy rotating targets, the device can still ensure the smoothness and safety of the demolding process. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0029] like Figure 1-3 As shown, a blank demolding device for rotating target material includes a base 1, a support column 3, a bearing platform 4, a fixing component 5, a lead screw 6, a transmission mechanism, a motor 8, and a track 9.

[0030] The base 1 has two parallel tracks 9, and two support pillars 3 are located near one end of each track 9. The two support pillars 3 are distributed on the outer side of the two tracks 9 and are perpendicular to the surface of the base 1. Normally, the base 1 is placed on the ground or a table and is horizontal, so the support pillars 3 are vertical.

[0031] A support platform 4 is provided between the two support pillars 3, and the four corners of the support platform 4 are threadedly connected to four lead screws 6. Two lead screws 6 are provided on the outer side of each track 9. The lower end of each lead screw 6 is rotatably connected to the base 1, for example, through the cooperation of the lead screw 6 and a bearing to achieve the rotatable connection on the base 1. In this way, the four lead screws 6 rotate under the drive of the motor 8 through the transmission mechanism, which can realize the vertical lifting and lowering of the support platform 4.

[0032] The motor 8 is located at the end of the base 1. The transmission mechanism is a chain drive mechanism, including a main drive chain 7-2 and a side drive chain 7-1. The side drive chain 7-1 is used to drive two lead screws 6 located on the same side outside the track 9. The main drive chain 7-2 is used to connect the motor and the two lead screws 6 on both sides of the track 9 and close to the motor. Accordingly, sprockets that can mesh with the main drive chain 7-2 or the side drive chain 7-1 need to be installed at the lower part of the lead screws 6. Furthermore, two sprockets need to be installed on the two lead screws 6 close to the motor 8 to connect the main drive chain 7-2 and the side drive chain 7-1 respectively, or a double row of sprockets can be used. Through the cooperation of the main drive chain 7-2 and the side drive chain 7-1, the driving force of the motor 8 can drive the four lead screws 6 to rotate, realizing the vertical lifting of the support platform 4. Preferably, the motor 8 in this utility model is a geared motor.

[0033] In other embodiments, a synchronous belt drive mechanism can be used instead of a chain drive mechanism. The synchronous belt drive mechanism includes a main drive synchronous belt and a side drive synchronous belt, with a synchronous pulley mounted on the lead screw.

[0034] Alternatively, the motor can be a dual-output motor, with a rotating shaft connected to each end. The shaft end of each rotating shaft is driven to the adjacent lead screw through a bevel gear set, which drives the lead screw to rotate. The lead screws on the same side are also connected to each other through a bevel gear set and a rotating shaft, thereby realizing the rotation of the four lead screws.

[0035] like Figure 2 , 3As shown, the supporting platform 4 includes an outer lifting platform 4-1 and an inner sliding platform 4-2. The four corners of the lifting platform 4-1 are threadedly connected to the four lead screws 6. The left and right sides of the sliding platform 4-2 are slidably supported on the support surface inside the lifting platform 4-1. The lower surface of the sliding platform 4-2 is equipped with rollers 4-3 for sliding along the track 9. Preferably, the rollers 4-3 are arranged in two rows, with at least two rollers 4-3 in each row. The rollers 4-3 in the same row run within one track 9 to ensure the stability of the sliding platform 4-2's movement. The sliding direction of the sliding platform 4-2 on the lifting platform 4-1 is parallel to the length direction of the track 9. The lifting platform 4-1 has an opening on one side for the sliding platform 4-2 to slide out of the lifting platform 4-1. The supporting platform 4 adopts a split design, allowing the sliding platform 4-2 to be pulled out when the supporting platform 4 is lowered to its lowest position, so that the demolded blank can be removed or the blank and mold to be demolded can be placed on it.

[0036] Preferably, after the sliding table 4-2 slides into the lifting table 4-1, the surface of the sliding table 4-2 is flush with the surface of the lifting table 4-1. The surface size of the sliding table 4-2 is larger than the base diameter of the mold core to be demolded.

[0037] For example Figure 1 As shown, the two support pillars 3 are also equipped with fixing components 5, which are used to clamp the blank on the mold. The structure of the fixing component 5 is as follows: Figure 2 , 3 As shown, it includes a fixing ring 5-1 and a transverse support 5-2. The fixing ring 5-1 is composed of two semicircular rings connected together. The middle of the outer circumference of each semicircular ring is fixed to one end of a transverse support 5-2, and the other end of the transverse support 5-2 is fixed to the pillar 3 on the same side. Figure 4 , 5 As shown, the two ends of the semicircular ring in the circumferential direction are provided with threaded holes. When the blank needs to be clamped by the fixing ring 5-1, the two semicircular rings are put on the blank, and the ends of the two semicircular rings are connected together by the adjusting bolt 5-3. The blank can be clamped or loosened by adjusting the screwing degree of the adjusting bolt 5-3, or the clamping degree of the blank can be adjusted.

[0038] Preferably, a rubber layer or a layer of other flexible materials such as sponge is provided on the inner side of the fixing ring 5-1 at the position where it can contact the blank, so as to reduce wear on the blank.

[0039] Preferably, multiple fixing components are provided and arranged vertically at intervals to provide a better fastening effect for fixing the blank.

[0040] The following is a detailed explanation of how to use this device.

[0041] After the blank 2 of the rotating target material is formed in the mold, firstly, the elastic rubber sleeve on the outer layer of the mold is removed, exposing the blank 2 inside; at this time, the blank 2 is fitted onto the metal inner core of the mold inner core base 10, and then the mold inner core base 10 is placed on the sliding table 4-2, and then the sliding table 4-2 is pushed into the lifting platform 4-1 along the track 9; then, the motor 8 is started, and the bearing platform 4 and the mold inner core are raised as a whole through the rotation of the lead screw 6 until the blank 2 enters the fixing ring 5-1, and multiple fixing rings 5-1 are distributed in the middle of the blank 2; then, the adjusting bolt 5-3 is manually tightened so that the fixing ring 5-1 holds the blank 2 tightly, and then the electric... The machine 8 reverses, causing the support platform 4 to descend. During this process, because the blank 2 is held tightly by the fixing ring 5-1 and the mold core itself has a large weight, the mold core descends with the support platform 4, achieving demolding of the blank 2 on the core. Finally, when the support platform 4 reaches the bottom, the rollers 4-3 on the sliding table 4-2 are supported in the corresponding track 9. Then, the sliding table 4-2 is pulled to remove it from the lifting platform 4-1. After removing the mold core, the support platform 4 is raised again to support the demolded blank 2. The adjusting bolts 5-3 on the fixing ring 5-1 are loosened, and the support platform 4 is lowered again to remove the blank 2. Thus, the demolding process of the rotating target blank is completed.

[0042] In this embodiment, the lifting and lowering of the bearing platform 4 is achieved by four lead screws 6. In other embodiments, the vertical lifting and lowering of the bearing platform 4 can also be achieved by using a traction lifting mechanism, a scissor lifting mechanism, or a hydraulic lifting mechanism.

[0043] For example, when using a traction lifting mechanism, a bracket can be set on the outer side of each of the two tracks 9 to replace the support column 3 in this embodiment. The fixing component 5 is connected to the bracket, and the lifting motor of the traction lifting mechanism is fixed on one of the brackets. The lifting motor drives two rotating wheels to rotate through a synchronous shaft. Each rotating wheel is connected to a traction component, and the lower end of the traction component is connected to the lifting platform 4-1 of the carrying platform 4. The traction component can be a traction rope or chain, etc. However, it should be noted that when using a traction lifting mechanism, a corresponding guide component needs to be set to ensure that the carrying platform 4 can be raised and lowered smoothly. The guide component can be a guide rod and a guide sleeve or other guide structure. The guide sleeve is fixed on the lifting platform 4-1, and the guide rod is vertically fixed on the base 1.

[0044] For example, two sets of scissor lift mechanisms are used, which are respectively set below the support platform 4 and connected to the base 1 and the lifting platform 4-1. A linear drive mechanism, not limited to an electric push rod, provides driving force for the scissor lift mechanism to realize the vertical lifting of the support platform 4.

[0045] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
