Description

Steel ball quenching machine

Technical field

The invention relates to a steel ball quenching machine, which is used for rapidly cooling a steel ball after rolling forming in a quenching medium such as water or oil, thereby improving the strength, toughness and fatigue strength of the steel ball and the like. Physical properties, belonging to the field of quenching facilities for metal materials. Background technique

In the case of building materials production industries such as cement plants, in the process of producing cement, it is necessary to ball mill the ore (known in the industry as grinding), and ball milling requires a large number of steel balls with ideal wear resistance and high hardness. The quenching machine used for quenching steel balls, which is more common in the prior art, is composed of a cylinder 8 and a cylinder driving mechanism 9 which are inclined (one end is high and the other end is low) as shown in FIG. The two ends of the cylinder 8 are not sealed, and the outer center of the cylinder 8 is machined with an annular cylindrical ring gear 81, and the inner wall of the cylinder 8 is machined with a ring-shaped or spiral-shaped steel ball guiding rib 82, which is driven by the cylinder body. The motor 91 of the motor 9 is further rotated by the speed reducer 92 and the driving gear 921 fixed on the power output shaft of the speed reducer 92 and meshed with the ring gear 81 of the cylinder, and the cylinder 8 is rotated while the cylinder 8 is rotated. The feeding ball 83 introduces a steel ball which has been subjected to roll forming by a rolling mill into the cylindrical cavity of the cylindrical body 8. At the same time, the quenching medium is primarily introduced into the barrel by water from line 84. Under the rotational movement of the tubular body 8, the steel ball that enters the cylindrical cavity (the left end of the drawing) from the cylindrical body 8 into the cylindrical cavity is taken out by the ball outlet 85 (the right end of the figure), and finally by the extraction mechanism 851. Lift away. The advantage of the above device is that the structure is simple, the equipment investment is extremely small, especially the equipment can be made by the enterprise. However, quenching, that is, quenching treatment efficiency and efficiency are not flattering. As far as the effect of the quenching treatment is concerned, since the steel ball cannot be prevented from being piled up in the cavity of the cylinder 8, the uniform quenching effect cannot be obtained between the steel ball and the steel ball or the steel ball itself, for example, The steel ball and the steel ball are attached to each other, so that the steel ball can not get a good overall quenching from the surface and the inside, and the hardness (HRC) is different, generally around 20-40. In the process of use, the steel ball has poor wear resistance and easy deformation, which brings frequent replacement of steel balls to the production industry, increases the use cost, and infers the ball milling efficiency due to deformation, which affects normal production; If the balls are fed into the barrel of the barrel 8 through the feeding ball 83 in a large amount, the physical properties of the steel balls are worse due to the serious pile-up, and conversely, if they are fed one by one, not only the medium for quenching is wasted. And it will cause inefficiency in energy consumption, because the cylinder 8 is passively in a state of starvation that tends to be idling. Summary of the invention

The quenching medium transport mechanism 4, wherein the ball feeding mechanism 2 is interposed between the steel ball transport mechanism 1 and the steel ball spiral separation quenching mechanism 3. The steel ball picking mechanism 1 serves to feed the steel ball 6 from the rolling mill to the ball feeding mechanism 2, and further feeds the steel ball spiral separation quenching mechanism 3 to the ball feeding mechanism 2 for quenching.

Referring to FIG. 2, the specific structure of the preferred steel ball transport mechanism 1 is given. The specific shape and configuration of the first frame 11 as the steel ball transport mechanism 1 are not limited by the illustration, and it may have various A structural form of variation. At the one end of the first frame 11, a pair of rail inclined beams 111 which are parallel to each other and which are arranged in a slope are mounted. The slope setting referred to here can be understood from the figure, that is, one end of the chain rail beam 111 is high. Further, the other end is low, and further, the end of the pair of chain rails 111 which is fixed to the first frame 11 is higher, and the one end which extends to the cooling pool 19 is low, thereby forming a gradient or a gradient. A conveyor chain raceway 1111 is formed on each of the top surfaces of the pair of rail rails 111. The conveyor chain raceway 1111 may be integrally formed on the rail rail beam 111 or may be separately fixed to the rail rail oblique beam. In the 111, the fixing manner may be a splicing, or may be achieved by using a fastener or by other similar means. A first transmission device 14 is disposed at the top of the other end of the first frame 11, and the first transmission device 14 includes a first motor 141 and a first reduction gear 142, which are assembled according to common knowledge, that is, the first motor 141 The power output shaft is coupled to the power input shaft of the first reduction gear 142, and the power output shaft of the first reduction gear 142 is coupled to one end of the first sprocket shaft 15 via the coupling 1421, and both ends of the first sprocket shaft 15 The pivot is placed on a pair of first bearing blocks 151, and the first bearing block 151 is fixed on the first frame 11. In the middle of the first sprocket shaft 15 A pair of first sprocket wheels 152 are fixed at a distance, and the degree of separation between the two is determined by the spacing between the pair of chain rails 111, that is, a pair of first sprocket wheels. 152 correspond to the high end ends of the pair of chain rails 111, respectively. One end of the conveyor chain 17 is respectively sleeved on a pair of first sprocket wheels 152, and the other ends of the pair of conveyor chains 17 are respectively sleeved on a pair of second sprocket wheels 162, and a pair of second sprocket wheels 162 are fixed Corresponding to the middle of the second sprocket shaft 16 at the lower end of the slant beam 111, the two ends of the second sprocket shaft 16 are respectively pivoted on the corresponding second bearing seats 161, and the second bearing block 161 is mounted on the cooling On a pair of bearing seat seats 1611 in the tank 19, the cooling pool 19 serves to cool the hopper 18, and when the hopper 18 passes through the cooling pool 19, the cooling medium such as water in the cooling tank 19 is sucked to prevent the hopper 18 from being heated. The red steel ball is burnt. The lower end of the aforementioned pair of chain rails 111, i.e., the illustrated right end, may be supported on the pair of housing mounts 1611. The hopper 18 is coupled to a pair of conveyor chains 17 via a hopper shaft 181. When the first transmission 14 drives the first sprocket shaft 15 to move, a pair of first sprocket wheels 152 on the first sprocket shaft 15 drive a pair of conveyor chains 17 to move. During the movement, the conveyor chain 17 should be along The conveyor chain raceway 1111 is running. As is clear from the figure and according to common knowledge, during operation, the hopper 18 is rotated around the first and second sprockets 152, 162 by the conveyor chain 17, thereby forming a continuous transport steel ball 6 transport. Plane or transfer plane. The steel ball 6 is introduced by the raceway 12. For the raceway 12, either the channel steel or the iron plate can be directly used, and the latter is selected in this embodiment. The raceway 12 is fixed to the bracket 121 illustrated by Fig. 1, the narrowed end of which corresponds to the lower end of the hopper 18, that is, the lower end, and the other end is expanded and extended to the rolling mill for rolling the steel ball. At the ball mouth, the steel ball 6 formed by the rolling mill rolling is rolled into the hopper 18 via the raceway 12, and is lifted up by the running hopper 18 to the ball of the main race 13 fixed to the first frame 11. The mouth is fed to the ball feeding mechanism 2 via the main raceway 13.

Referring to Fig. 3, the ball feeding mechanism 2 is responsible for feeding the steel ball 6 introduced by the main race 13 of the steel ball transport mechanism 1 to the steel ball spiral separation quenching mechanism 3 which will be described later in detail. As the second frame 21 of the ball feeding mechanism 2, the specific shape and configuration thereof are also not limited by the illustration, and the second speed reducer 22 is bolted to the side of the second frame 21 (the right side of the figure). The power output shaft 221 of the second reduction gear 22 is laterally extended and fixed to the center of the steel ball branching disk 23 by a flat key. Applicant has already mentioned that the present embodiment is directed to two sets of steel ball spiral separation quenching mechanisms 3, and therefore is formed on the rim of the steel ball tributary disk 23 in a state of being separated one by one. The cavities of the middle and side ball storage chambers 231, 232, the middle and side ball storage chambers 231, 232 should satisfy the extent to which the steel balls 6 introduced by the main races 13 of the steel ball transport mechanism 1 can be accommodated. The steel ball 6 pulled into the middle ball storage chamber 231 is fed to the center raceway 24, and the center raceway 24 is fixed to the second frame 21, and the first ball end 241 at one end of the figure shown at the left end corresponds to the middle road storage. The ball cavity 231, and since the center raceway 24 is disposed at a height, one end of the first ball-opening port 241 is higher than the right of the figure The first ball outlet 242 of the end, so when the first ball entrance 241 is connected to the steel ball 6, the steel ball 6 automatically rolls down to the first ball outlet 242, and then feeds the two sets shown in FIG. The steel ball spirally separates a rear quenching mechanism in the quenching mechanism 3; the steel ball 6 drawn into the side ball storage chamber 232 is fed into the ball side ball race 26, and the ball side track 26 is fixed in the second On the frame 21, the second ball-opening port 261 on one end side corresponds to the second ball-out port 2322 of the side ball storage cavity 232, and also because the ball-side ballway 26 is inclined at both ends. The end of the second ball opening 261 is higher than the end of the third ball opening 262, so when the second ball outlet 2322 of the side ball storage cavity 232 feeds the steel ball 6 to the ball side track. At the second ball entrance 261 of 26, the steel ball 6 is automatically rolled down to the third ball exit 262, and is fed to the front quenching mechanism of the two sets of steel ball spiral separation quenching mechanisms 3 illustrated in the figure. . In order to ensure that the steel ball 6 in the side ball storage chamber 232 is smoothly fed to the ball side ball race 26, a bevel surface 2321 is machined in the bottom wall of each side ball storage chamber 232. If a side ball storage cavity is added to the middle and side ball storage chambers 231, 232 on the steel ball branching plate 23 to form a left, right, and middle storage ball cavity, that is, a left, right, middle, The left, right and middle storage cavity forms are used to satisfy the feeding requirements of the three sets of steel ball spiral separation quenching mechanism 3, in which case it should be considered equivalent to the technical solution of the present invention. The rotation of the steel ball branching disc 23 is achieved by the second speed reducer 22, and the power of the second speed reducer 22 is applied to the auger 31 of the steel ball spirally separating the quenching mechanism 3, specifically by a power transition device 25. The third sprocket 251 of the device is fixed to the power input shaft of the second reduction gear 22, and the fourth sprocket 253 of the device is fixed to the aforementioned auger 31, and the first chain 252 of the device The second sprocket 253 is driven by the auger 31, and the third sprocket 251 is driven by the first chain 252 to operate the second reducer 22, and then the second sprocket 22 The speed reducer 22 rotates the steel ball yoke 23 to complete the receiving and feeding of the steel balls 6 during the rotation.

Referring to FIG. 3 and continuing with FIG. 1, the preferred pair (two sets) of steel ball spiral separation quenching mechanisms 3 of the present invention are disposed in parallel with each other above the medium collection tank 36. For the medium collection tank 36, from an economical point of view It is considered that it is preferable to use the floor of the use site, that is, to excavate a pool body like a pond on the floor, and then to pour concrete. Of course, it is also possible to process a container into a container as a medium collection tank 36, and then install it to the production site, but the cost of the latter is significantly higher than the former. Applicants need to explain here: Since the structure and installation method of the two sets of steel ball spiral separation quenching mechanism 3 are basically the same, only the power transmission device is shared, so only one set is shown in Fig. 4, the following The description is also for a set.

The auger 31 has an inclined arrangement in which one end is high and the other end is low, which can be fully understood by the illustration of FIG. The spiral piece 313 is integrally formed on the rod body of the auger 31, and the spacing between the adjacent spiral pieces 313 is adapted to the size (diameter) of the steel ball 6, if the diameter of the steel ball 6 is 90 mm, 25 mm or the like , then the spacing between the flights 313 should meet the steel with the largest diameter The accommodation requirements of the ball 6. The two ends of the auger 31, that is, the right and left ends of the currently illustrated position, are respectively pivoted on the first and second auger bearing blocks 3111 and 3112 through the first and second auger bearings 311 and 312, respectively. The second auger bearing blocks 3111, 3112 are respectively fixed on the first and second abutments 37, 38, and the first and second abutments 37, 38 are respectively fixed on the aforementioned medium collecting pool 36, both of which remain Corresponding, that is, the two are on the same line. Wherein: the first pedestal 37 is fixed on the pool edge of the medium collecting pool 36, and the second pedestal 38 is fixed on the medium collecting pool 36, and the two are in correspondence, that is, the two are on the same line, wherein: The seat 37 is fixed to the bottom of the tank of the medium collecting tank 36, and the difference in height generated between the two determines the inclination of the auger 31. The steel ball 6 fed by the center race 24 of the ball feeding mechanism 2 and the ball side ball race 26 enters between the spiral pieces 313 of the screw 31 at the lower end, and the steel ball 6 is rotated under the rotation of the screw 31. The process of climbing from the bottom up until the removal, the steel ball 6 is carried by the spiral piece 313 from the bottom to the top is the quenching process. Since there is only one steel ball 6 between the two adjacent spiral pieces 313, the pile-up phenomenon between the steel balls 6 does not occur as in the prior art, so that the steel balls 6 can obtain the same quenching effect as above, and pass through the below. The quenching medium conveying mechanism 4, which will be described in detail, continuously supplies a quenching medium such as well water or tap water or river water to each of the spiral pieces 313, thereby avoiding an increase in the overall water temperature and affecting the quenching quality.

A medium groove 32 having a U-shaped cross-sectional shape is disposed below a region corresponding to the spiral piece 313 on the auger 31. The function of the medium groove 32 is to correspond to the quenching medium to which the quenching medium conveying mechanism 4 is transported. The quenching medium is water (the same below). The medium tank 32 is fixed to the top end of the medium tank holder 321, and the bottom end of the medium tank bracket 321 is fixed to the bottom wall of the medium collecting tank 36. Since the auger 31 is disposed at a height, the medium groove 32 maintains a step-by-step relationship, that is, the one end is high and the other end is low. In order to prevent the medium in the medium groove 32 from being splashed from the lower end (the left end of the drawing) in a large amount, the second auger bearing 312 is affected, so that the water retaining disk 33 is provided on the auger 31 corresponding to the lower end. According to common knowledge, the further the position of the water retaining plate 33 on the auger 31 is from the lower end of the medium groove 32, the greater the outflow of the quenching medium in the medium groove 32, and vice versa, because the medium groove 32 is inclined. Further, since the steel ball 6 is moved from the lower end to the upper end, the temperature of the steel ball 6 is lowered from the height.

Referring to FIG. 1 in detail, the movement of the auger 31 is secured by the second transmission 34. The second motor 341 of the second transmission 34 is in driving engagement with the second reduction gear 342 and is mounted on the second frame 3411. The sprocket 343 is fixed to the shaft end of the power output shaft of the second reduction gear 342, one end of the second chain 344 is sleeved on the fifth sprocket 343, and the other end of the second chain 344 is sleeved on the sixth sprocket 347. The sixth sprocket 347 is fixed to the shaft end of the main shaft 346, and the main shaft 346 is pivoted on a pair of main shaft bearing housings 3461. The main shaft bearing housing 3461 is disposed on the bearing housing bracket 3462. The left end of the main shaft 346 (the illustrated positional state is an example) is coupled to the right end end of the auger 31, that is, the upper end, by the universal joint 345. Since this embodiment is directed to two sets of steel ball spiral separation quenching mechanism 3 In other words, the power of the preceding set of steel ball spiral separation quenching mechanisms 3 illustrated in Figure 1 is obtained by a transition chain 348 coupled to a subsequent quenching mechanism. Specifically, the sixth sprocket 347 is a double-row sprocket, one end of the transition chain 348 is sleeved on the sixth sprocket 347, the other end is sleeved on the seventh sprocket 349, and the seventh sprocket 349 is fixed. On the other main spindle 346, the other main shaft 346 is also coupled to the auger shaft 31 of the preceding set of steel ball spiral separation quenching mechanism 3 through the corresponding universal joint 345, thereby realizing two sets of steel ball spiral separation. The quenching mechanism 3 moves synchronously. The steel balls 6 to be quenched obtained by the two sets of steel ball spiral separation quenching mechanism 3 are respectively fed by the aforementioned steel ball side ball race 26 and the center raceway 24, and the quenching is completed under the movement of the auger 31, and The quenched steel ball 6 is driven out to the ball rolling track 35. Since the ball rolling path 35 fixed to the first holder 37 is in an inclined state, it is ensured that the steel ball 6 is rolled down to the ball container 7 placed in the ball collecting pool 71. A guide door 351 is pivotally disposed on the passage of the ball exit raceway 35 for guiding the steel ball 6 into the corresponding ball container 7. Further, in order to protect the second motor 341, the shaft end of the spindle 346 is additionally provided. The safety clutch 3463 is opened by the safety clutch 3463 upon encountering an increase in load due to a situation such as a block of the auger 31, and functions as a safety protection for the second motor 341. While the steel ball spiral separation quenching mechanism 3 is operating, the quenching medium conveying mechanism 4 is always in the state of conveying the medium.

Referring to FIG. 1 and FIG. 4 , the medium manifold 41 of the quenching medium conveying mechanism 4 recommended by the present invention is connected to a medium supply source, and the medium supply source may be a tap water source or a separately equipped well pump station (also referred to as a well pump station). Groundwater pump room). Applicant selects the well pump station. A plurality of water inlets for controlling the flow rate of the control valve 42 are connected to the medium manifold 41, and the water outlet of the control valve 42 is connected to the corresponding classifying pipe 43, and each of the classifying pipes 43 is connected to one end of a group of branch pipes 44. The other end of the branch pipe 44 is connected to the medium groove 32 of the steel ball spiral separation quenching mechanism 3. In the figure, although the applicant shows that the number of the plurality of control valves 42 is three, and the number of the plurality of classification tubes 43 is three, it is not limited by the illustration. The preferred number of branch tubes 44 is adapted to the flight 313 to ensure that the cavity formed by the two adjacent flights 313 corresponds to a branch pipe 44, thereby achieving separation of the flight 313 on the auger 31. the goal of. The amount of the medium (the amount of water) introduced into the medium tank 32 is increased from left to right by the positional state shown in the figure, so that the center raceway 24 and the steel ball side raceway 26 are fed. The steel balls 6 are quenched, in particular by adjustment of the respective control valves 42. The water agitated by the spiral piece 313 of the auger 31 enters the medium collecting tank 36 and is returned to the well pumping station for reuse. In order to prevent the temperature of the recycled water from being reused, the new well water can be replenished to make the water temperature Control is around 20-3CTC. Example 2:

Please refer to FIG. 5, which shows an example of only one set of steel ball spiral separation quenching mechanism 3, in this case In this case, the ball feeding track of the ball feeding mechanism 2 only needs the center raceway 24, and the second ball-out port 2322 of the side ball storage chamber 232 on the steel ball branching plate 23 is closed, forming a middle road. The ball storage chamber 23 has the same structural form. And, there is no transition chain 348. And, only one set of quenching medium conveying mechanism 4 is required, and the rest is the same as that of Embodiment 1. Application Example 1:

Since the main raceway 13 is engaged with the ball feeding mechanism 2, the steel ball 6 is transferred from the main raceway 13 to the ball splitter disk 23 which is transferred to the ball feeding mechanism 2, and the steel ball splitter disk 23 is The steel ball spirally separates the quenching mechanism 3 to drive the second reduction gear 22 to rotate under the operation, and the steel ball 6 introduced into the middle and side ball storage chambers 231, 232 by the main race 13 is distributed to the center race 24 and the steel ball. The side raceway 26, the first and third ball outlets 242, 262 of the center ball race 24 and the ball side ball race 26 are respectively fed to a pair of steel balls spirally separating the spirals on the auger 31 of the quenching mechanism 3 Between slices 313. Since the quenching medium conveying mechanism 4 at this time is also in an operating state, that is, the quenching (cold) medium (water) is supplied into the medium tank 32, the steel ball 6 entering between the spiral pieces 313 is under the movement of the auger 31, The movement of the steel ball 6 from the lower end of the medium groove 32 (the left end shown in Figs. 1, 4) to the high end (the right end shown in Figs. 1, 4) is about 20-27S. Or 55-65S, if the diameter of the steel ball 6 is 25mm, then the time required is 20-27S, and if the diameter of the steel ball is 90, then the time required is about 55-65S, so the rotation speed of the auger 31 is The diameter of the steel ball 6 is inversely proportional. The steel ball 6 which has been blasted from the high end of the medium tank 32 by the spiral piece 313 and which has completed the quenching process is dropped into the ball container 7 which is prepared at the end of the ball rolling path 35 via the ball rolling path 35. Applicants will test the steel balls quenched by this embodiment in six batches of six batches, and each time they are tested by 20 delivery authorities, the results show that the hardness has reached an extremely satisfactory level, and the HRC values are all above 68. Moreover, the hardness from the spherical surface to the center of the sphere is uniform, and the steel ball obtained by the quenching machine shown in FIG. 6 (the HRC is only 20-40) has a remarkable hardness improvement, and is resistant to wear. The damage and deformation resistance are self-evident. In addition, the quenching efficiency can be increased by 5-6 times compared with the prior art. Application Example 2:

The steel ball 6 is quenched by a single set of steel ball spiral separation quenching mechanism 3 as shown in FIG. 5, which is lower in efficiency than the application example 1, but the hardness (HRC) after quenching is also inferior. The hardness of the steel ball 6 obtained in Application Example 1. The rest is the same as the description of application example 1.
