Description

Technical Field

[0001] The utility model belongs to the field of production equipment, relates to the field of steel ball production, and particularly relates to an automatic ball pushing device in front of a ball cooling platform. Background Art

[0002] In the process of producing wear-resistant steel balls, the formed steel balls are first subjected to high-temperature quenching. After quenching, the steel balls need to be cooled down and then sent into a tempering furnace for tempering to adjust the hardness, strength, plasticity and toughness of the workpiece, so that the steel balls meet the service performance requirements.

[0003] The temperature of the steel balls after quenching is relatively high. If the quenched steel balls are directly tempered at high temperature, it may cause the steel balls to overheat and affect the performance of the steel balls. By cooling the steel balls to a certain temperature, the tempering temperature can be better controlled to avoid overheating. Currently, it is usually necessary to cool the steel balls to room temperature before tempering, so that the starting temperature of tempering can be more accurately controlled, thereby obtaining a balance of the expected hardness, strength, plasticity and toughness.

[0004] After quenching, the steel balls are transported to the ball cooling platform by a hoist to cool down. When the hoist transports the steel balls, a ball track is needed to connect with the ball cooling platform to ensure that the high-temperature steel balls can roll smoothly onto the ball cooling platform for cooling. Content of the Utility Model

[0005] The utility model provides an automatic ball pushing device in front of a ball cooling platform to solve the technical problem that high-temperature steel balls can roll smoothly onto the ball cooling platform for cooling. When the high-temperature steel balls roll in the ball track, their rolling rate is delayed by a heat-insulating damping curtain, avoiding collision damage of the steel balls in the ball track. After collecting the steel balls in rows, they are centrally discharged onto the ball cooling platform, which is flexible and efficient in use.

[0006] The technical solution adopted by the utility model is: to provide an automatic ball pushing device in front of a ball cooling platform, which includes a frame. A ball track is arranged in the frame in a lifting manner by means of a guiding driving member. The bottom surface inside the ball track is inclined. An inlet and an outlet are respectively arranged at both ends in the length direction of the ball track, and the height of the inlet is higher than that of the outlet. An intercepting member is arranged at the outlet of the ball track. The intercepting member is fixedly installed on the frame and abuts against the end surface of the outlet of the ball track. A heat-insulating damping curtain is evenly arranged in the ball track along the length direction.

[0007] The lane is erected and lifted inside the frame. When the lane is supported to a low position, its inlet is connected to the ball outlet of the elevator so that the quenched steel balls can roll from the elevator into the lane. The bottom surface of the lane is inclined, with its inlet height higher than the outlet height, causing the steel balls to roll to the outlet of the lane and be connected by the intercepting member at the outlet, causing the steel balls to accumulate in the lane. When the steel balls roll towards the outlet, they continuously contact the heat insulation and damping curtain erected in the lane. The curtain contacts the steel balls, providing frictional resistance to the steel balls, slowing down the rolling speed of the steel balls, preventing the steel balls from colliding and being damaged, ensuring the use safety. Then the lane moves up, disconnecting the outlet from the intercepting member and connecting it to the ball cooling platform, causing the steel balls to roll onto the ball cooling platform, which is simple and smooth to use.

[0008] To further optimize this technical solution, the frame includes a base. Both the guiding and driving member and the intercepting member are fixedly installed on the base. And support seats are fixedly installed at both ends in the length direction of the base, and the top surfaces of the support seats are in contact with the bottom surface of the lane.

[0009] The base supports the support seats and the guiding and driving member, and the support seats support the lane, making it stable and reliable when the steel balls roll from the elevator into the lane.

[0010] To further optimize this technical solution, the guiding and driving member includes a linear driving member fixedly installed in the middle of the base and straight rods that are circumferentially distributed along the top surface of the base and are vertically arranged; the output end of the linear driving member is fixedly installed on the bottom surface of the lane, and the straight rods are fixedly installed on the top surface of the base, and the lane is slidably installed on the straight rods by means of a slideway assembly.

[0011] Straight rods are separately arranged on the periphery of the lane. When the linear driving member assembled with the base drives the lane to move up and down, the lane moves up and down along the straight rods by means of the slideway assembly. The slideway assembly prevents the lane from shaking and tilting, ensuring the smoothness and stability of the lifting.

[0012] To further optimize this technical solution, the slideway assembly includes "C" steel fixedly installed on the straight rods respectively and pulleys fixedly installed on the outer wall of the lane. The pulleys correspond to the positions and quantities of the "C" steel respectively, and the pulleys are slidably assembled with the "C" steel respectively.

[0013] The pulleys assembled on the periphery of the lane are assembled with the "C" steel assembled on the straight rods. The "C" steel restricts the pulleys, and the pulleys slide along the steel grooves of the "C" steel, ensuring the stability of the movement.

[0014] To further optimize this technical solution, the linear driving member is a hydraulic cylinder. The hydraulic cylinder is fixedly installed on the base, and the output end of the hydraulic cylinder is fixedly installed on the bottom surface of the lane.

[0015] The hydraulic cylinder of the linear driving member has a simple structure, is stable and reliable in use, and has a low use cost.

[0016] Further optimize this technical solution. The intercepting member includes an intercepting plate fixedly installed on the top surface of the base, and the end surface of the intercepting plate abuts against the end surface of the ball track outlet.

[0017] After the intercepting plate assembled with the base abuts against the end surface of the ball track outlet, it prevents the steel balls in the ball track from rolling down. After the ball track is lifted, the outlet of the ball track gradually gets out of the intercepting range of the intercepting plate, so that the outlet of the ball track loses the shield, and the steel balls in the ball track can roll smoothly onto the ball cooling platform.

[0018] Further optimize this technical solution. The heat-insulating damping curtain includes a connecting rod detachably installed on the ball track, and ceramic fiber tapes are evenly and detachably installed on the bottom surface of the connecting rod.

[0019] The ceramic fiber tapes are assembled on the bottom surface of the connecting rod and are supported on the ball track by the connecting rod. In this way, the steel balls contact the ceramic fiber tapes, providing frictional damping for the rolling of the steel balls, slowing down the rolling rate of the steel balls. Moreover, the ceramic fiber tapes have high-temperature resistance characteristics, avoiding damage to them caused by high-temperature steel balls, extending their service life, and ensuring the reliability of use.

[0020] Further optimize this technical solution. Slots are provided at both ends of the bottom surface of the connecting rod, and the slots are inserted into the outer wall of the ball track.

[0021] The connecting rod is inserted and supported on the sliding groove by the slots provided at both ends of the bottom surface. The assembly is simple and the use is stable.

[0022] Further optimize this technical solution. Connecting pieces are evenly arranged on the bottom surface of the connecting rod along the length direction. The number and positions of the connecting pieces correspond to those of the ceramic fiber tapes, and the ceramic fiber tapes are tightened and fixed to the connecting pieces by bolts.

[0023] The ceramic fiber tapes are tightened and fixed to the connecting pieces on the bottom surface of the connecting rod by bolts, which is convenient for disassembling and maintaining the ceramic fiber tapes and makes the use flexible.

[0024] Further optimize this technical solution. The inner surface of the ball track is coated with a heat-insulating coating.

[0025] The heat-insulating coating applied inside the ball track avoids high-temperature damage to the ball track caused by high-temperature steel balls, extends the service life of the ball track, and ensures the safety of use.

[0026] The beneficial effects of the present utility model are as follows:

[0027] 1. The inner bottom surface of the ball track is inclined, with its inlet height higher than the outlet height. After the steel balls enter the ball track from the inlet, they roll towards the outlet. The ceramic fiber tapes supported in the ball track contact the steel balls, providing frictional damping for the steel balls, slowing down the rolling rate of the steel balls, avoiding mutual collision and damage of the steel balls, ensuring the reliability of use. Moreover, the ceramic fiber tapes are resistant to high temperatures, which can avoid damage to them caused by high-temperature steel balls, extend their service life, and ensure the safety of use;

[0028] 2. When the ball track is placed on the support base to load steel balls, the support of the hydraulic cylinder on the ball track is released to ensure the safety of the hydraulic cylinder. When the hydraulic cylinder operates to push the ball track upward, the "C" steel erected by the straight rod on the circumferential side of the ball track provides guidance and restraint for the pulley on the side wall of the ball track, making the lifting of the ball track stable and smooth, and avoiding the shaking and tilting of the ball track, ensuring the safety of use;

[0029] 3. When the ball track is lifted by the hydraulic cylinder, the outlet of the ball track gradually gets out of the interception range of the intercepting plate, so that the outlet of the ball track gradually loses the shelter. After its outlet is completely exposed, the steel balls in the ball track smoothly roll onto the ball cooling platform. After the steel balls in the ball track are emptied, the ball track falls onto the support base again to continue loading steel balls, with flexible use. Description of the Drawings

[0038] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0039] Please refer to the attached Figures 1-3, An automatic ball - topping device in front of a cool - ball platform, comprising a frame 1. Inside the frame 1, a ball track 2 is vertically lifted and lowered by a guiding and driving member. The frame 1 includes a base 101 for support. The base 101 is arranged between the elevator and the cool - ball platform, enabling the ball track 2 to connect the elevator and the cool - ball platform. The guiding and driving member is assembled on the base 101. The guiding and driving member includes a linear driving member 4 fixedly installed on the base 101. The linear driving member 4 can be a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly installed on the bottom surface 203 of the ball track 2. Straight rods 5 are circumferentially distributed on the top surface of the base 101. The straight rods 5 are vertically and fixedly installed on the base 101, and the ball track 2 is slidably installed with the straight rods 5 by a slideway assembly 6. When the hydraulic cylinder operates to drive the ball track 2 to lift and lower, the slideway assembly 6 makes the lifting and lowering of the ball track 2 stable. The slideway assembly 6 includes "C" - shaped steel 601 fixedly installed on the straight rods 5 respectively and pulleys 602 fixedly installed on the outer wall of the ball track 2. The pulleys 602 correspond to the positions and quantities of the "C" - shaped steel 601 respectively. The pulleys 602 are slidably assembled with the "C" - shaped steel 601 respectively. The "C" - shaped steel 601 guides the pulleys 602, making the lifting and lowering of the ball track 2 smooth and stable;

[0040] Please refer to the appendix Figure 1 and the appendix Figures 3-5 , At both ends of the base 101 in the length direction, support seats 102 are fixedly installed. After the hydraulic cylinder drives the ball track 2 to fall, the ball track 2 falls onto the support seats 102. The top surface of the support seats 102 abuts against the bottom surface 203 of the ball track 2, thus relieving the support of the hydraulic cylinder on the ball track 2 and ensuring the safety of the use of the hydraulic cylinder. When the support seats 102 support the base 101, an inlet 201 and an outlet 202 are respectively arranged at both ends of the ball track 2 in the length direction. The ball outlet of the elevator is connected to the inlet 201 of the ball track 2 so that steel balls can roll into the ball track 2. The bottom surface 203 of the ball track 2 is inclined, and the height of the inlet 201 of the ball track 2 is higher than the height of the outlet 202 of the ball track 2. Thus, the steel balls roll along the bottom surface 203 of the ball track 2 towards the outlet 202 of the ball track 2. An intercepting member is arranged at the outlet 202 of the ball track 2. The intercepting member includes an intercepting plate 7 fixedly installed on the base 101. The end face of the intercepting plate 7 abuts against the end face of the outlet 202 of the ball track 2, thereby preventing the steel balls from rolling out of the ball track 2 and making the steel balls stack in rows inside the ball track 2;

[0041] Please refer to the appendix Figure 4 and the appendix Figures 6-7, along the length direction of the inner edge of the lane 2, heat insulation damping curtains 3 are evenly installed. The heat insulation damping curtain 3 includes a connecting rod 301 detachably installed on the lane 2. At both ends of the bottom surface 203 of the connecting rod 301, slot 3011 is provided, and the slot 3011 is inserted into the outer wall of the lane 2, making the assembly simple. On the bottom surface 203 of the connecting rod 301, ceramic fiber tapes 302 are evenly arranged. The ceramic fiber tapes 302 are assembled on the bottom surface 203 of the connecting rod 301 by means of connecting pieces 3012. The connecting pieces 3012 are fixedly arranged on the bottom surface 203 of the connecting rod 301, and the number and positions of the connecting pieces 3012 correspond to those of the ceramic fiber tapes 302. The ceramic fiber tapes 302 are fixed on the connecting pieces 3012 by tightening bolts, which is convenient for disassembly, assembly and maintenance. When the steel ball rolls along the lane 2 towards the outlet 202, the steel ball will continuously contact the ceramic fiber tapes 302, push the ceramic fiber tapes 302 away, and finally roll to the outlet 202 of the lane 2. The contact between the ceramic fiber tapes 302 and the steel ball provides frictional resistance to it, thereby slowing down the rolling speed of the steel ball, so as to avoid the collision damage caused when the steel balls are stacked in rows in the lane 2, improve the use safety, and the ceramic fiber tapes 302 have the characteristic of high temperature resistance, which can avoid the damage caused by high-temperature steel balls to it and extend its service life;

[0042] Please refer to the appendix Figure 2 , after the steel balls are stacked at the outlet 202 in the lane 2, the hydraulic cylinder drives the lane 2 to move upward, so that the outlet 202 of the lane 2 is connected with the cool ball platform. During the upward movement of the lane 2, the outlet 202 of the lane 2 gradually gets out of the interception range of the interception plate 7, so that the outlet 202 of the lane 2 loses the shelter, so that the steel balls in the lane 2 can roll smoothly onto the cool ball platform, and after emptying the steel balls in the lane 2, the hydraulic cylinder pulls the lane 2 back onto the support seat 102 to continue loading steel balls. And when realizing the automatic loading and discharging of steel balls, by installing sensors at the inlet 201 and outlet 202 of the lane 2, and using the sensors to detect the position of the steel balls. After the inlet 201 of the lane 2 detects the steel balls, the loading of the steel balls in the lane 2 is completed, and the hydraulic cylinder drives the lane 2 to move upward so that the steel balls can roll onto the cool ball platform. After the sensor at the outlet 202 of the lane 2 fails to detect the steel balls, the steel balls in the lane 2 are emptied, and the hydraulic cylinder pulls the lane 2 back to the support seat 102 to continue loading steel balls, improving the degree of automation;

[0043] The working principle of the automatic ball topping device in front of the cooling ball platform is as follows: When the ball track 2 lands on the support base 102, the support of the hydraulic cylinder is released to ensure the safety of the hydraulic cylinder during use. The inlet 201 of the ball track 2 is connected to the ball outlet of the elevator. The quenched steel balls roll from the ball outlet into the ball track 2 and roll down along the inclined bottom surface 203 of the ball track 2 towards its outlet 202, and are connected by the intercepting plate 7 at the outlet 202, causing the steel balls to accumulate in the ball track 2. During the process of the steel balls rolling along the ball track 2, they continuously come into contact with the heat-insulating damping curtain 3 in the ball track 2, thereby providing frictional force to the steel balls, delaying the rolling rate of the steel balls, reducing the force of contact and collision of the steel balls, avoiding damage to the steel balls, improving the safety of steel ball transfer, and the ceramic fiber belt 302 material of the heat-insulating damping curtain 3 has high-temperature resistance characteristics, avoiding damage caused by high-temperature steel balls and extending its service life;

[0044] After the steel balls accumulate at the inlet 201 in the ball track 2, the hydraulic cylinder drives the ball track 2 to move upward, causing the outlet 202 of the ball track 2 to gradually move out of the intercepting range of the intercepting plate 7. After the outlet 202 is connected to the cooling ball platform, the outlet 202 is completely out of interception, so that the steel balls can smoothly roll onto the cooling ball platform. After emptying the steel balls, the ball track 2 is pulled back onto the support base 102 to continue loading steel balls for smooth use;

[0045] When the hydraulic cylinder drives the ball track 2 to reciprocate up and down, the pulley 602 assembled on the periphery of the ball track 2 slides along the "C" shaped steel 601 vertically installed by the straight rod 5 on the periphery of the ball track 2. The pulley 602 is placed in the steel groove of the "C" shaped steel 601 to constrain and guide the pulley 602, avoiding the front and back tilting and shaking of the slideway and improving the stability of the up and down movement of the ball track 2.
