Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sword forging and pressing, and particularly relates to a sword blank hot rolling forming machine. BACKGROUND

[0002] Sword refers to the sword and sword in ancient weapons, also known as weapon general. The sword blank is the basic material of the sword body processed by forging process, which needs to go through the process of 100 times steelmaking in traditional casting, including folding forging, quenching and other processes.

[0003] The rolling machine is a mechanical equipment for processing a smooth rod, mainly applied to the fields of motor, cylinder, oil cylinder, valve, linear bearing and oil pumping machine manufacturing. The equipment improves the surface quality of the smooth rod through the rolling process, so that the surface roughness is reduced from Ra3.2~6.3μm to Ra0.1~0.8μm, the hardness is increased by about 30%, the fatigue strength is increased by 25%, and the processing efficiency is increased by 15 times compared with the grinding process. The basic feature of the smooth rod is the processing of a slender shaft, which is difficult to process and has strict requirements on coaxiality, straightness, smoothness and wear resistance, which has always been a difficult problem for processing personnel. By using rolling processing, the surface layer has surface residual stress, which helps to close the small cracks on the surface and hinder the expansion of the erosion effect. Thus, the surface corrosion resistance is improved, and the generation or expansion of fatigue cracks is delayed, thereby improving the fatigue strength of the oil cylinder rod. Through rolling forming, a cold hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the grinding contact surface, thereby improving the wear resistance of the smooth rod surface, and avoiding the burn caused by grinding. After rolling, the surface roughness value is reduced, which can improve the fitting property. At the same time, the friction damage of the sealing ring or sealing element during the movement of the smooth rod piston is reduced, and the overall service life of the component is improved.

[0004] The patent file with the publication number CN116550775A is a sword blank hot rolling forming machine, which rolls and moves the blank by placing it between two pressure rollers, rotates two connecting plates to drive the connecting plate to fit on the top of the blank, and at the same time the driven plate is pushed by the reaction force of the blank to drive the sliding rod, and then the sliding plate is pulled by the connecting line to drive the two limiting plates, so that the limiting plate limits the side wall of the top of the blank, and the blank is kept horizontal during rolling, which avoids the influence of forging quality due to direction deviation during movement.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] The sword embryo hot rolling forming machine positions the embryo between two pressure rollers, positions the embryo being flattened and shaped by the pressing plate and the limiting plate to avoid the embryo from deviating during movement, but in the actual application process, the mutually parallel pressure rollers can only obtain part of the sword body, cannot process the blade part, compared with the traditional forging and pressing method, generally can only achieve the effect of thinning the embryo plate, and it is difficult to directly form the sword embryo, and the production work of the sword handicraft is completed after subsequent polishing.

[0048] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0049] Example 1:

[0050] This embodiment describes the specific structure of a hot roll forming machine for sword blanks, see details below. Figures 1-8 , Figure 12 , Figure 13 As shown, it includes a first support 5 and a second support 6 arranged symmetrically on the left and right, a support roller 12, a movable roller 11 arranged on the top of the support roller 12, and two cutting rollers 16 arranged symmetrically on the top and bottom. A rolling limit assembly 9 is arranged between the two cutting rollers 16. A linkage control assembly 8 is arranged between the two cutting rollers 16, the movable roller 11, and the support roller 12. A pad frame 13 is arranged at the bottom of the linkage control assembly 8. A base frame 14 is assembled and connected to the bottom of the pad frame 13. A motor 1 and a reducer 2 are assembled and connected to the top of one end of the base frame 14. The motor 1 reduces the rotational speed of the shaft through the gear set in the reducer 2, and an active gear 3 is interference-fitted to the outside of the power output shaft of the reducer 2. A driven gear 4 is meshed and connected to the top of the active gear 3.

[0051] The linkage control assembly 8 includes two supporting plates 801 arranged front and rear. Universal joints 806 are provided between the top and bottom sides of the two supporting plates 801. A connecting shaft 815 is provided between the two universal joints 806 in the horizontal direction. The movable roller 11 and the cutting edge roller 16 are located at both ends of the supporting plates 801 respectively. The four connecting shafts 815 are respectively located between the two supporting plates 801 and are assembled and fixed to one end of the movable roller 11, the support roller 12 and the two cutting edge rollers 16. The end of the support roller 12 away from the universal joint 806 passes through the interior of the first support 5 and is pinned to the interior of the driven gear 4.

[0066] Based on the above-mentioned second hydraulic cylinder 10 and linkage control assembly 8, when the movable roller 11 moves towards the bottom to approach the support roller 12, the linkage control assembly 8 controls the two blade rollers 16 to approach each other away from the second support 21, the two universal joints 806 and the connecting shaft column 815 can transmit power between the blade roller 16 and the movable roller 11 or the blade roller 16 and the support roller 12, and the distance between the movable roller 11 and the support roller 12 and the minimum distance between the two blade rollers 16 can be adjusted synchronously.

[0067] The above design can realize the synchronous rotation of the horizontally arranged support roller 12 and the obliquely arranged blade roller 16 by starting the motor 1 to drive the driving gear 3 to rotate the driven gear 4 under the cooperation of the reducer 2, thereby driving the support roller 12 to rotate, and synchronously controlling the blade roller 16 at the bottom to rotate through the universal joint 806 and the connecting shaft column 815 between the two bearing vertical plates 801 at the bottom.

[0068] In the production process of the sword, the sword embryo needs to be treated for hardness and toughness first, and forged into the basic shape of the sword. Then the sword embryo in the cooling state is preheated to ensure its certain deformation ability, and is placed between the movable roller 11 and the supporting roller 12. With the rotation of the supporting roller 12, the sword embryo can be rolled to the target thickness by the friction force, and pass through the movable roller 11 and the supporting roller 12;

[0069] At the same time, the sword embryo is placed between the two edge rollers 16, and the rolling limiting assembly 9 is used to limit the movement of the sword embryo between the two edge rollers 16 along the axial section. The two edge rollers 16 with an acute angle can roll out the blade on the sword embryo, without subsequent processing of the blade, which is conducive to directly forming the sword artware.

[0070] In addition, when the first supporting seat 17 is controlled to move up and down by the second hydraulic cylinder 10, the supporting roller 12 drives the supporting seat block 814 between the bottoms of the two overlapping arms 804 to move up and down, and the movable roller 11 is controlled to move close to or away from the supporting roller 12, realizing small-range adjustment of the thickness of the sword embryo hot-rolled and formed. With the driving arm 805 connected with the overlapping arm 804 and moving up and down, the first sliding rod 811 can be controlled to push and pull the push-pull arm 808 under the cooperation of the sliding block 812 and the limiting bar slot 22, so as to realize the control of the second sliding rod 813 connected with the movable arm 807 to move up and down by pushing and pulling the two movable arms 807 through the push-pull arm 808, and finally achieve the effect of controlling the two supporting seat blocks 814 close to the edge roller 16 to move close to or away from each other, so as to adjust the two edge rollers 16 away from the one end of the second seat 6 to move close to each other.

[0071] It is worth noting that if the degree of change of the inclination state of the two edge rollers 16 needs to be adjusted, only the inclination angle of the driving arm 805 needs to be adjusted. One end of the locking screw 810 is threadedly connected in the inside of the positioning gear 809. After the driving arm 805 is pressed on the surface of the overlapping arm 804, the ratio of the right angle side of the right triangle formed by the inclination of the driving arm 805 is used to control the ratio between the up-and-down movement distance of the driving arm 805 and the horizontal movement distance of the push-pull arm 808, which is conducive to controlling the degree of movement of the two movable arms 807 pushing and pulling the two supporting seat blocks 814, so as to achieve the effect of controlling the degree of change of the inclination state of the edge roller 16.

[0074] Among them, the threaded long rod 907 is movably connected in the inner side of the threaded rod seat 906, the middle part of the Y-shaped frame 905 is slidably connected in the inner side of the extension support 904, the bottom of the limiting insert plate 909 is sleeved on the outer side of the threaded long rod 907 through the opening 27, the limiting insert plate 909 is located on one side of the threaded rod seat 906, by limiting the threaded long rod 907 from moving along the axial direction when they cooperate with each other, when the threaded long rod 907 is controlled to rotate by means of the operating rod 908, the threaded connection between the threaded long rod 907 and the Y-shaped frame 905 is adjusted, the Y-shaped frame 905 is controlled to slide in the inner side of the extension support 904, the sword positioning seat 901 at the top of the two U-shaped seats 902 of the Y-shaped frame 905 is moved, so as to adjust the position of the sword positioning seat 901 between the two edge rollers 16, which is beneficial to assisting the hot rolling of the blade of the sword blank between the two edge rollers 16, the opposite side which is not processed or is not processed is supported by the sword positioning seat 901, and in the process of rolling the blade, the sword blank moves between the two edge rollers 16, and the sword positioning seat 901 moves in the inner side of the two U-shaped seats 902;

[0075] At the same time, in order to ensure that the blade surface rolled on the sword blank is flat, the side of the sword positioning seat 901 away from the inner wall of the U-shaped seat 902 is arranged in a state suitable for the final state of the product, so as to ensure that the sword blank to be rolled is in a horizontal state;

[0076] In addition, in order to make the sword positioning seat 901 move smoothly in the inner side of the two U-shaped seats 902 during the rolling process of the blade, Figure 11 As shown, the inner sides of the two U-shaped seats 902 are both provided with a plurality of rollers 911, by making the surfaces of the plurality of rollers 911 all fit the surface of the third slot 30, the support of the rollers 911 can be utilized to reduce the friction between the sword positioning seat 901 and the U-shaped seat 902 when the surface of the side of the sword positioning seat 901 away from the second support 6 is pressed.

[0077] Secondly, in order to avoid that the sword positioning seat 901 is disconnected with the two U-shaped seats 902 during the movement of the sword positioning seat 901 in the inner side of the two U-shaped seats 902, Figure 11As shown, the top of one U-shaped seat 902 is connected with the second limiting strip 910 by pin connection, the bottom of another U-shaped seat 902 is connected with the first limiting strip 903 by pin connection, the inside of the sword positioning seat 901 is provided with a third slot 30, the top of one end of the sword positioning seat 901 is provided with a first notch 28, the bottom of another end of the sword positioning seat 901 is provided with a second notch 29, the first notch 28 and the second notch 29 are connected with the inside of the third slot 30, the first limiting strip 903 is movably connected in the second notch 29 and the third slot 30, and the second limiting strip 910 is movably connected in the first notch 28 and the third slot 30, so that the activity range of the sword positioning seat 901 can reach the maximum value during the process that the sword positioning seat 901 supports the sword blank to process the blade and moves with the sword blank, and the sword positioning seat 901 can avoid being connected with only one U-shaped seat 902, and the sword blank supported by the sword positioning seat 901 can completely pass through the two edge rollers 16 when the sword blank is supported by the sword positioning seat 901 to process the blade.

[0078] The design above controls the rotation of the threaded long rod 907 through the operating rod 908, adjusts the threaded connection between the threaded long rod 907 and the Y-shaped frame 905, controls the sliding of the Y-shaped frame 905 in the inside of the extension support 904, drives the sword positioning seat 901 at the two U-shaped seats 902 on the top of the Y-shaped frame 905 to move, and adjusts the position of the sword positioning seat 901 between the two edge rollers 16, so that the sword positioning seat 901 can adapt to the width of the sword blank and be beneficial to assisting the hot rolling and pressing of the blade of the sword blank between the two edge rollers 16.

[0079] Meanwhile, the opposite side of the sword blank which is not processed or is not processed is supported by the sword positioning seat 901, the sword positioning seat 901 is supported by the plurality of rollers 911, the sword positioning seat 901 moves with the sword blank when the sword blank is rolled and pressed between the two edge rollers 16, the first limiting strip 903 passes through the support of the second notch 29, the inner wall of one end of the third slot 30 close to the first notch 28 blocks the limiting, the second limiting strip 910 passes through the support of the first notch 28, the inner wall of one end of the third slot 30 close to the second notch 29 blocks the limiting, so that the activity range of the sword positioning seat 901 can reach the maximum value, and the sword blank supported by the sword positioning seat 901 can completely pass through the two edge rollers 16 when the sword blank is processed.

[0080] It is worth noting that the sword blank which is processed to have a blade is a sword with the same width of the sword body, or is a knife which needs to keep the same shape as the sword and only processes the blade on one side of the sword body.
