Description

Technical Field

[0001] The utility model relates to a target material processing platform, in particular to a material tooling platform for forging and processing pure gold target materials. Background Art

[0002] The processing process of pure gold target material is to first cast the raw material (Au purity>99.999%, Au alloy target alloy element tolerance ±0.5%) into a metal ingot through a smelting equipment, and then undergo heat treatment and forging to improve the grain size (average grain size <100um, maximum grain size <150um), and then use a tablet press, hydraulic press and other equipment to roll the metal ingot to the required thickness of the target embryo and make it flat, and finally the target embryo is machined, polished and other processes to obtain the required size specifications and surface roughness (Ra≤1.6).

[0003] Existing forging equipment needs to be heat treated before forging. During heat treatment, the metal ingot is generally heated to a suitable temperature through a muffle furnace before forging. The whole step is repeated 4 to 5 times to change the grain size of the metal ingot. However, in this process, it is often transported by manual clamping, which is done 4 to 5 times back and forth. Due to the high density and heavy weight of the metal ingot, it is very difficult to clamp it. The temperature of the heated metal ingot is very high, which is more dangerous during transfer, and the accuracy of the transfer is difficult to guarantee. If it is only by clamping, it will need to be adjusted many times before reaching the predetermined position. Utility Model Content

[0004] The utility model provides a material tooling platform for forging pure gold target materials, which can not only adopt an automatic transmission method for loading and unloading materials, thereby reducing the turnover difficulty of metal ingots and improving the turnover accuracy in a single processing cycle, but also can reduce the load borne by the tooling during the forging process, ensure the forging strength while preventing the tooling from being affected by the forging, and can effectively solve the above-mentioned problems.

[0005] The utility model is achieved in this way:

[0006] A material tooling platform for forging pure gold target material, comprising: an automatic material guiding mechanism, including two transmission frames, a long groove is opened on the inner side of the transmission frame, a base for carrying a workpiece is movably arranged in the long groove, a movable part is movably connected to the front end of the base, and a plurality of positioning pressure groups are arranged at the bottom of the inner side of the long groove. When the positioning pressure group descends, the movable part drives the base to slide along the long groove. When the base moves into place, the movable part is separated from the base, and the positioning pressure group rises and retracts into the transmission frame;

[0007] The movable separation structure includes a hollow tube column arranged on the side of the base close to the movable part, and a movable shaft tube cooperating with the hollow tube column is arranged on the side of the movable part close to the base. A power part is arranged on the movable part, and the power part is connected to the movable shaft tube. When the movable part moves, the movable shaft tube is pushed into the hollow tube column, and the movable shaft tube is expanded by the power part so that the movable shaft tube is clamped in the hollow tube column, so that the movable shaft tube can drive the base to reciprocate in the horizontal direction.

[0008] As a further improvement, the upper surface of the base is provided with a plurality of limiting ribs, and the limiting ribs are arc-shaped bar structures.

[0009] As a further improvement, the base comprises a placement table for placing the workpiece, and V-shaped bending plates are provided on both sides of the placement table. The side of the bending plate away from the placement table is slidably fitted in the long groove through a contact plate.

[0010] As a further improvement, the positioning pressure group includes a plurality of positioning cylinders fixedly connected to the inner wall of the transmission frame, and an abutment pile is connected to the output end of all the positioning cylinders. All the abutment piles are in the same horizontal line after being pushed out to the lowest end, and the upper surfaces of the movable part and the base are in contact with the lower end of the abutment pile when moving.

[0011] As a further improvement, a guide bar is provided in the long slot, the movable part includes a sliding motor provided in the long slot and cooperating with the guide bar, a connecting plate is connected between the two sliding motors, and the movable shaft tube is fixedly connected to the connecting plate.

[0012] As a further improvement, a separator is provided on one side of the connecting plate facing the punching table, and the separator is flush with the placement table. When the movable shaft tube is matched with the hollow pipe column, the separator fits with the side of the placement table.

[0013] As a further improvement, the hollow tube column includes a transverse lumen fixedly connected to the placement table, the transverse lumen is connected to a longitudinal lumen, the transverse lumen and the longitudinal lumen form a T-shaped structure, the movable shaft tube includes a straight rod cooperating with the longitudinal lumen, the two sides of the end of the straight rod are opened, and a movable elastic pin is arranged in the opening, and the power member applies pressure to the inside of the straight rod to push the elastic pin out and clamp it in the transverse lumen.

[0014] As a further improvement, an arc-shaped groove is provided on the top of the punching table, and a convex shaft is welded to the bottom of the base, and when the base slides to the upper part of the punching table, the convex shaft cooperates with the arc-shaped groove.

[0015] The beneficial effects of the utility model are:

[0016] In existing forging equipment, conventional stamping tables are often set as liftable structures, which will directly cause the stamping table to drop or be damaged during forging, greatly affecting the forging effect. Therefore, the utility model adds an automatic material guiding mechanism, and sets a base that can be moved by movable parts between the forger and the stamping table. After the movement, the base will be directly located above the stamping table and fit tightly with the stamping table, thereby avoiding setting the stamping table to a liftable state. The base can transfer the force applied during forging to the stamping table without loss, and when forging is required after moving to the exact position, the movable part can be separated from the base, so that the impact force received by the base will not affect the normal use of the movable part, thereby achieving the effect of assisting movement without being affected by forging.

[0017] In order to prevent the workpiece that falls onto the base from being greatly deviated during movement, the utility model also provides a plurality of limiting ribs on the upper surface of the base, which limit the position of the workpiece in a small range without affecting the forging effect on the workpiece.

[0018] If the entire base is set as an integral plate structure, although its hardness is sufficient, it is subjected to very large vibrations. Due to the relatively small space, it is impossible to set up a shock-absorbing structure. Therefore, the utility model sets up the base in multiple sections. First, there is a placement table with load-bearing capacity, which is used to carry the workpiece, and V-shaped bending plates are set on both sides of the placement table to make it partially deformed during the forging stage to relieve the forging force. Finally, a certain matching relationship is formed between the contact plate and the long groove, so that the entire base can move along the direction of the long groove.

[0019] In the process of the movable part cooperating with the base, the hollow tube column and the movable shaft tube are coordinated. When the movable part moves, the movable shaft tube will be embedded in the hollow tube column, thereby promoting the base. In order to improve the movement accuracy of the base, a power part is also arranged on the movable part, which can produce a tighter clamping relationship between part of the movable shaft tube and the hollow tube column, so that the movement accuracy of the movable part can be directly replaced by the movement accuracy of the base.

[0020] In order to make the hollow tube column and the movable shaft tube better cooperate, the hollow tube column and the movable shaft tube are both set to two sections, which are coordinated by the two sections. First, the longitudinal cavity tube and the straight rod are sleeve-type coordinated, and then the elastic pin and the transverse cavity tube are clamped. The movable part and the base form a perfect match, so that the base can achieve the required accuracy whether it moves forward or backward, and can be accurately located in the center of forging.

[0021] In the lateral position of the movable part and the base, the movable part and the base are limited by the positioning pressure group to guide their movement. However, during forging, the entire base including the edge is affected. Therefore, during the forging stage, the entire positioning pressure group of the utility model is retracted upward and has no contact with the base. Therefore, when the base is forged, the positioning pressure group is not affected, thereby avoiding affecting the accuracy of the positioning pressure group.

[0022] The positioning pressure group is set across the entire transmission frame, so that the movable parts and the base can be accurately guided when moving. The positioning pressure group uses a liftable positioning cylinder to push all the abutment piles down to the same straight line, thus forming a complete guide surface. When guidance is not needed, the abutment piles are lifted up by retracting the positioning cylinder.

[0023] During forging, the positioning pressure group and the movable parts are completely separated from the base, so that the base is subject to minimal restrictions and may be displaced during forging. Therefore, the utility model arranges an arc groove on the stamping table and a convex shaft on the base. When the base reaches the correct position, it will cooperate with the stamping table, so that the base is fixed, and the base will not shift due to forging without a movable structure to fix it.

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0036] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] Reference Figures 1 to 10As shown, a material tooling platform for forging pure gold target material comprises a forging table 10, a forging press 20 is arranged on the top of the inner side of the forging table 10, a punching table 30 is arranged on the bottom of the inner side of the forging table 10, and the forging press 20 forges the workpiece on the punching table 30 when it descends, and the forging equipment also comprises: an automatic material guiding mechanism, comprising two transmission frames 41 arranged between the forging press 20 and the punching table 30, a long groove is opened on the inner side of the transmission frame 41, a base 42 for carrying the workpiece is movably arranged in the long groove, a movable part 43 is movably connected to the front end of the base 42, and a plurality of positioning pressure groups 44 are arranged on the bottom of the inner side of the long groove, and when the positioning pressure group 44 descends, the movable part 43 drives the base 42 to slide along the long groove straight To the top of the stamping table 30, when the base 42 moves to the top of the stamping table 30, the movable part 43 is separated from the base 42, and the positioning pressure group 44 rises and retracts into the transmission frame 41; the movable separation structure includes a hollow tube column 51 arranged on the side of the base 42 close to the movable part 43, and the side of the movable part 43 close to the base 42 is provided with a movable shaft tube 52 that cooperates with the hollow tube column 51, and a power part 53 is arranged on the movable part 43, and the power part 53 is connected to the movable shaft tube 52. When the movable part 43 moves, the movable shaft tube 52 is pushed into the hollow tube column 51, and the movable shaft tube 52 is stretched open by the power part 53, so that the movable shaft tube 52 is clamped in the hollow tube column 51, so that the movable part 43 drives the base 42 to reciprocate in the horizontal direction.

[0038] In this embodiment, a muffle furnace can be set at the front end of the forging equipment, and a muffle furnace can also be set at the rear end of the forging equipment, so that the forging equipment in this embodiment can realize continuous calcination-forging. In this embodiment, the forged workpiece is a metal ingot, wherein the distance between the two transmission frames 41 is greater than the diameter of the forger 20.

[0039] In the existing forging equipment, the workpiece to be forged is often transferred by manual clamping. A single transfer may have little effect, but in order to obtain a sufficient forging effect, the calcination-forging process needs to be continued for 4 to 5 times. If it is simply transferred manually, it is not only time-consuming and labor-intensive, but also easy to cause poor installation accuracy. In addition, the conventional punching table 30 is often set as a liftable structure, which will directly cause the punching table 30 to fall or be damaged during the forging process, which will greatly affect the forging effect. Therefore, the utility model adds an automatic material guiding mechanism in the forging press 20. A base 42 that can be moved by a movable part 43 is set between the stamping table 30. After the movement, the base 42 will be directly located above the stamping table 30 and fit tightly with the stamping table 30, thereby avoiding the need to set the stamping table 30 to a liftable state. The base 42 can transfer the force during forging to the stamping table 30 without loss. When forging is required after moving to the exact position, the movable part 43 can be separated from the base 42, so that the impact force on the base 42 will not affect the normal use of the movable part 43, thereby achieving the effect of assisting movement without being affected by forging.

[0040] In order to prevent the workpiece that falls onto the base 42 from being greatly deviated during movement, a plurality of limiting ribs 45 are provided on the upper surface of the base 42. The limiting ribs 45 are arc-shaped structures. By providing a plurality of limiting ribs 45 on the upper surface of the base 42, the position of the workpiece can be limited in a small range by using the limiting ribs 45 without affecting the forging effect on the workpiece. The limiting ribs 45 and the base 42 can be movably mounted, so that the corresponding number of limiting ribs 45 can be adjusted according to the size of the workpiece.

[0041] If the entire base 42 is set as an integral plate structure, although its hardness is sufficient, the vibration it is subjected to is very large. Due to the relatively small space, it is impossible to set a shock-absorbing structure. Therefore, the utility model sets the base 42 in multiple sections. Specifically, the base 42 includes a placement table 421 for placing workpieces, and V-shaped bending plates 422 are set on both sides of the placement table 421. The side of the bending plate 422 away from the placement table 421 is slidably fitted in the long groove through a contact plate 423. First, the placement table 421 with load-bearing capacity is used to carry the workpiece, and V-shaped bending plates 422 are set on both sides of the placement table 421, so that it undergoes partial deformation during the forging stage to relieve the forging force. Finally, a certain matching relationship is formed with the long groove through the contact plate 423, so that the entire base 42 can move along the direction of the long groove.

[0042] In the process of the movable part 43 cooperating with the base 42, the hollow tube column 51 and the movable shaft tube 52 cooperate with each other. When the movable part 43 moves, the movable shaft tube 52 will be embedded in the hollow tube column 51, thereby promoting the base 42. In order to improve the movement accuracy of the base 42, a power part 53 is also arranged on the movable part 43, which can produce a tighter clamping relationship between part of the movable shaft tube 52 and the hollow tube column 51, so that the movement accuracy of the movable part 43 is directly replaced by the movement accuracy of the base 42.

[0043] The power member 53 of this embodiment is an air pump structure, which has the functions of positive and negative pressure, and is located below the movable member 43 without forming any obstruction to the overall structure.

[0044] In this embodiment, a guide bar is provided in the long slot, and the movable part 43 includes a sliding motor 431 provided in the long slot and cooperating with the guide bar. A connecting plate 432 is connected between the two sliding motors 431, and the movable shaft tube 52 is fixedly connected to the connecting plate 432, wherein the connecting plate 432 does not serve as a load-bearing carrier, but as an installation carrier.

[0045] In order to protect the hollow tube column 51 and the movable shaft tube 52 from being affected by forging sparks after the connecting plate 432 is close to the placement table 421, a partition plate 433 is provided on the connecting plate 432 facing the side of the stamping table 30. The partition plate 433 is flush with the placement table 421. When the movable shaft tube 52 and the hollow tube column 51 are matched, the partition plate 433 fits with the side of the placement table 421, and a partition surface is isolated by the partition plate 433.

[0046] In order to make the hollow tube column 51 and the movable shaft tube 52 better cooperate, the hollow tube column 51 and the movable shaft tube 52 are both set to two sections, and cooperate with each other through the cooperation of the two sections. Specifically, the hollow tube column 51 includes a transverse cavity tube 511 fixedly connected to the placement table 421, and the transverse cavity tube 511 is connected to a longitudinal cavity tube 512, and the transverse cavity tube 511 and the longitudinal cavity tube 512 form a T-shaped structure, and the movable shaft tube 52 includes a straight rod 521 that cooperates with the longitudinal cavity tube 512, and the straight rod 521 The two sides of the end are opened, and movable elastic pins 522 are arranged in the openings. After the power member 53 applies pressure to the inside of the straight rod 521, the elastic pin 522 is pushed out and clamped in the transverse cavity 511. First, the movable member 43 and the base 42 are tightly matched through the sleeve-type cooperation of the longitudinal cavity 512 and the straight rod 521, and then through the clamping cooperation of the elastic pin 522 and the transverse cavity 511, so that the base 42 can achieve the required accuracy whether it moves forward or backward, and can be accurately located in the center of forging.

[0047] In the lateral position of the movable part 43 and the base 42, the movable part 43 and the base 42 are limited by the positioning pressure group 44 to guide their movement. However, during forging, the entire base 42 including the edges are affected. Therefore, during the forging stage, the entire positioning pressure group 44 of the utility model is retracted upward and has no contact with the base 42. Therefore, when the base 42 is forged, the positioning pressure group 44 is not affected, thereby avoiding affecting the accuracy of the positioning pressure group 44.

[0048] The positioning pressure group 44 is arranged to span the entire transmission frame 41, so that the movable part 43 and the base 42 can be accurately guided when moving. Specifically, the positioning pressure group 44 includes a plurality of positioning cylinders 441 fixedly connected to the inner wall of the transmission frame 41, and an abutment pile 442 is connected to the output end of all the positioning cylinders 441. All the abutment piles 442 are in the same horizontal line after being pushed to the lowest end. The upper surfaces of the movable part 43 and the base 42 are in contact with the lower ends of the abutment piles 442 when moving. The positioning pressure group 44 uses the liftable positioning cylinders 441 to push all the abutment piles 442 down to the same straight line, thereby forming a complete guiding surface. When no guidance is needed, the abutment piles 442 are lifted up by retracting the positioning cylinders 441.

[0049] During forging, the positioning pressure group 44 and the movable part 43 are completely separated from the base 42, so that the base 42 is subject to very little restriction and may be displaced during forging. Therefore, an arc groove is provided on the top of the stamping table 30 of this embodiment, and a convex shaft 424 is welded to the bottom of the base 42. When the base 42 slides to the upper part of the stamping table 30, the convex shaft 424 cooperates with the arc groove. By providing an arc groove on the stamping table 30 and a convex shaft 424 on the base 42, when the base 42 reaches the exact position, it will cooperate with the stamping table 30, so that the base 42 is fixed, and the base 42 will not shift due to forging in the absence of a movable structure to fix it.

[0050] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
