Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment and relates to the field of production equipment, in particular to a ball-forming device for steel ball quenching equipment. Background Art

[0002] When producing and processing steel balls, especially wear-resistant steel balls, the steel balls need to be quenched after forging and rolling in order to obtain stronger wear resistance, so that the hardness of the surface and core of the steel balls is uniform, so that the steel balls can play a better wear-resistant advantage in wear-resistant equipment such as mining ball mills and reduce production wear.

[0003] When quenching a steel ball, a ball track is fixed to the ball entrance of the quenching tank. An auger is installed within the tank. After the steel ball rolls into the quenching tank along the ball track, it is moved forward along the tank by the continuously rotating auger. This ensures that the ball's position and the auger's spiral blades are in a constant state of alternation. When the quenched steel ball fits perfectly between the auger's two spiral blades, it enters the auger smoothly and is propelled forward by the auger. When the auger's spiral blades pass beyond the optimal ball-entry position, the blade tips rub against the surface of the steel ball, causing the steel ball to swirl forward and backward. Once the spiral blades rotate to a position where the steel ball can enter, the steel ball enters between the blades.

[0004] When the spiral blades of the auger come into contact and rub against the steel balls, the balls can easily get stuck between the auger and the wall of the ballway. When the balls get stuck, the machine needs to be shut down in time and the balls need to be cleaned. Since the temperature of the steel balls to be quenched is relatively high, there are certain operational risks when cleaning the steel balls. In addition, there is a large amount of water vapor at the quenching site, which interferes with the operator's vision and further increases the operational risk. If the downtime is long, the temperature of the steel balls to be quenched on the production line will drop, and the temperature return of the normally quenched steel balls in the quenching pool will be low, making them fail to meet the process execution requirements and requiring secondary heating treatment. This not only wastes energy, but also reduces production efficiency and increases production and processing costs.

[0005] If the machine cannot be shut down in time, the friction between the steel ball and the auger will damage the auger and the auger's drive mechanism. The maintenance and replacement of the equipment and parts will greatly reduce production efficiency and increase production costs. Utility Model Content

[0006] This utility model aims to solve the technical problem of steel balls easily getting stuck due to friction with the auger when entering the quenching tank. It provides a ball-scoring device for steel ball quenching equipment. The movable baffle provides space for the steel ball to move, ensuring the optimal scoring position of the steel ball on the auger, preventing the steel ball from getting stuck, and improving the smoothness and safety of use.

[0007] The technical solution adopted by the utility model is: to provide a goal-scoring device for steel ball quenching equipment, including an auger assembled in the quenching pool and a ball track erected at the goal entrance of the quenching pool, a baffle and a positioning slide are respectively provided on one side of the end of the ball track, the baffle and the positioning slide are arranged on the same side of the ball track, and the baffle and the positioning slide are distributed front and back; the baffle is rotatably hinged in the ball track by means of a connecting piece, a locating pin is fixedly installed on the side wall of the free end of the baffle, the free end of the locating pin passes through the positioning slide and is equipped with an anti-slip part, and the locating pin is slidably assembled with the positioning slide; a support spring is sleeved on the outer wall of the locating pin, and the two ends of the support spring are respectively in contact with the outer wall of the baffle and the outer wall of the ball track.

[0008] When the steel ball rolls along the ball track into the quenching pool, after it rolls to the end of the ball track, the baffle is tilted and supported in the ball track by the support spring, so that the steel ball needs to roll into the quenching pool along the baffle. After the steel ball enters the ball opening of the quenching pool, when it is located between the two spiral blades of the auger, the steel ball falls smoothly into the quenching pool and is transported forward by the auger. When the steel ball fails to fall smoothly into the quenching pool and rubs against the spiral blades, the spiral blades push the steel ball to rotate the baffle, providing space for the steel ball to move so that it can smoothly enter between the two spiral blades. When the baffle rotates, it compresses the support spring to generate a reaction force. When the steel ball fails to enter the quenching pool when pushing the baffle, the baffle rebounds the steel ball, causing the steel ball to move forward again to enter between the spiral blades. In this way, the steel ball is allowed to fall into the quenching pool through multiple means to avoid the steel ball getting stuck. After the steel ball falls into the quenching pool, the support spring pushes the baffle to reset to continue transporting the steel ball, thereby improving the smoothness and flexibility of use.

[0009] To further optimize the technical solution, the connecting member includes a rotating shaft fixedly mounted on the baffle, both ends of the rotating shaft protrude from both ends of the baffle, and is rotatably mounted on the ball lane with the help of an assembly part.

[0010] The baffle is hinged to the ball track with the help of a rotating shaft. When the steel ball pushes the rotating shaft, the baffle rotates along the rotating shaft to provide moving space for the steel ball so that the steel ball can fall smoothly into the quenching pool.

[0011] To further optimize this technical solution, the assembly part includes an assembly groove opened at the bottom of the ball lane and a support piece fixedly installed on one side of the ball lane, the support piece protrudes upward from the ball lane and bends above the ball lane, and an assembly opening is opened on the support piece; the assembly opening is concentrically arranged with the assembly groove, and the two ends of the rotating shaft are rotatably installed with the assembly groove and the assembly opening respectively.

[0012] The opening at the top of the ball channel, after the support piece is fixedly installed on the ball channel, its top protrudes from the ball channel and bends above the ball channel to provide a support point for the assembly of the rotating shaft. After the rotating shaft is plugged into the assembly opening of the support piece, both ends of the rotating shaft are supported, ensuring the stability and reliability of the use of the rotating shaft, and the concentric setting of the assembly groove and the assembly opening ensures the accuracy of the use of the rotating shaft.

[0013] To further optimize the technical solution, bearings are swivel-mounted in the assembly groove and the assembly opening, and the bearings are sleeve-connected with the rotating shaft.

[0014] The bearing reduces the rotational resistance of the shaft, making it easier and smoother to drive the baffle to rotate, and the use is stable and smooth.

[0015] To further optimize the technical solution, a through hole is provided on the baffle, the through hole is interference-fitted with the rotating shaft, and through holes are formed at both ends of the rotating shaft.

[0016] The through hole on the baffle is assembled with the rotating shaft. The interference fit between the rotating shaft and the through hole enables the rotating shaft to drive the baffle to rotate synchronously to adjust the position of the baffle. Through holes are respectively passed through the two ends of the rotating shaft for assembly with the ball track. The structure is simple and the use is stable and reliable.

[0017] To further optimize the technical solution, the anti-slip component includes an anti-slip sheet threadedly assembled on the positioning pin, and the diameter of the anti-slip sheet is larger than the diameter of the positioning pin and larger than the width of the positioning slot.

[0018] When the baffle drives the positioning pin to slide along the positioning slot, the anti-slip sheet prevents the positioning pin from slipping out of the positioning slot, thereby restricting the travel of the baffle and ensuring reliability of use.

[0019] To further optimize the technical solution, a thread groove is provided on the end surface of the free end of the positioning pin, a bolt is threadedly connected in the thread groove, and the bolt is fixedly installed with the anti-slip sheet.

[0020] The anti-dropping piece is threadedly connected to the thread groove on the positioning pin by means of the assembled bolt, and is easy to assemble and disassemble, easy to use, and reduces the use cost.

[0021] To further optimize the technical solution, washers are provided at both ends of the support spring, the washers are slidably assembled with the positioning pins respectively, and the washers are respectively in contact with the outer wall of the baffle and the inner wall of the ball lane.

[0022] The support spring contacts the baffle and the ball track through gaskets provided at both ends, thereby reducing contact wear between the support spring, the baffle and the ball track and extending its service life.

[0023] The beneficial effects of the present invention are:

[0024] 1. When the spiral blades of the auger come into contact with the steel ball, the steel ball is driven to move, causing the steel ball to push the baffle to compress the support spring, thereby providing space for the steel ball to move so that the steel ball can re-enter the spiral blades of the auger. The compressed support spring generates a reaction force, which pushes the steel ball to rotate with the help of the baffle, so that it can enter between the spiral blades, increasing the diversity of the steel ball falling into the quenching pool, avoiding the steel ball from getting stuck, and improving the smoothness of use.

[0025] 2. The baffle is assembled on the ballway with the help of a rotating shaft. The assembly groove at the bottom of the ballway and the assembly opening on the support plate at the top of the ballway provide support points for the assembly of the rotating shaft. The concentric arrangement of the assembly opening and the assembly groove ensures the operating accuracy of the rotating shaft. The bearings in the assembly opening and the assembly groove reduce the rotation resistance of the rotating shaft, ensuring the smooth rotation of the baffle.

[0026] 3. When the baffle rotates along the rotating shaft to compress the support spring, the baffle pushes the positioning pin to move along the positioning slide groove. The positioning pin supports the support spring to prevent it from bending and affecting the use effect of the baffle. The anti-slip sheet assembled on the free end of the positioning pin prevents the positioning pin from falling off from the positioning slide groove. The anti-slip sheet constrains the travel of the baffle to ensure the reliability of the baffle. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Please see the attached Figure 2 , Attachment Figure 4 The locating pin 3 is fixedly mounted on the side wall of the free end of the baffle 201, and the free end of the locating pin 3 passes through the positioning slot 202. When the baffle 201 rotates along the ball track 2, the locating pin 3 is driven to move along the positioning slot 202. The free end of the locating pin 3 is equipped with an anti-slip piece to prevent the locating pin 3 from falling off from the positioning slot 202, ensuring the reliability of the use of the locating pin 3. The anti-slip piece includes an anti-slip piece threadedly assembled on the locating pin 3. The diameter of the anti-slip piece is larger than the diameter of the locating pin 3 and larger than the width of the positioning slot 202, preventing the locating pin 3 from falling off from the positioning slot 202.

The bolt 303 is fixedly mounted to the anti-slip piece, which has a simple structure and is stable in use.

[0038] Please see the attached Figure 2 , Attachment Figure 4 , Attachment Figure 6, a support spring 4 is sleeved on the outer wall of the positioning pin 3, and the support spring 4 is located between the baffle 201 and the ball lane 2. The support spring 4 supports the baffle 201 to make it inclined. Washers 401 are provided at both ends of the support spring 4. The washers 401 are respectively slidably assembled with the positioning pin 3, and the support spring 4 pushes the washers 401 to abut against the outer wall of the baffle 201 and the inner wall of the ball lane 2, thereby reducing the wear of the support spring 4 on the baffle 201 and the ball lane 2 and extending the service life of the support spring 4;

[0039] The working principle of the ball quenching device of the steel ball quenching equipment is as follows: the goal opening on the quenching pool 1 is opened on one side of the tail end of the quenching pool 1, and the ball channel 2 is tilted and erected on the goal opening. The ball channel 2 is high in the front and low in the back, and the slope ratio needs to ensure that the steel ball can roll downward at any position on the ball channel 2, so that the steel ball can roll smoothly into the quenching pool 1. The goal opening is located in the middle and lower part of the auger 101 in the quenching pool 1, which reduces the impact force of the steel ball on the groove wall of the quenching pool 1 when entering the quenching pool 1, thereby extending the service life of the quenching pool 1, and the width of the ball channel 2 for rolling the steel ball is based on the diameter of the largest steel ball processed. 2.5 times of the diameter is appropriate. After the steel ball rolls to the end of the ball channel 2, when the steel ball is just between the two spiral blades, the steel ball falls smoothly into the quenching pool 1 and is transported forward by the auger 101. When the steel ball rolls to the end of the ball channel 2, when its position with the spiral blades is not good, when the spiral blades contact and rub against the steel ball, the spiral blades push the steel ball to move to one side of the ball channel 2, thereby pushing the baffle 201 to rotate along the ball channel 2, thereby providing space for the steel ball to move, so that the steel ball has a position to enter between the spiral blades, avoiding the steel ball from getting stuck and improving the smoothness of the goal.

[0040] When the steel ball pushes the baffle 201 to rotate, it pushes the positioning pin 3 to move along the positioning slot 202 and compresses the support spring 4. When the steel ball falls into the quenching pool 1, the support spring 4 loses its constraint, pushes the baffle 201 to reset, and pulls the positioning pin 3 to reset along the positioning slot 202. The anti-slip plate at the free end of the positioning pin 3 limits the rebound stroke of the support spring 4, ensuring the optimal goal spacing of the steel ball and preventing the positioning pin 3 from falling off from the positioning slot 202, thereby ensuring reliability of use.
