Description

Technical Field

[0001] The present invention relates to the technical field of parts or accessories of furnaces, kilns, baking furnaces or distillation furnaces commonly used in more than one furnace, and in particular to a walking beam heating furnace for rods. Background Art

[0002] The rod heating furnace is an industrial device used to heat rods and is widely used in metal processing, forging, heat treatment and other fields.

[0003] When loading the rods into the heating furnace, since the size of the rods is generally large, it is often necessary to use a lifting device to lift the rods and then transfer them to the interior of the heating furnace. When using a lifting device to lift the rods, first, lift the rods to a higher position, then transfer them to the upper end of the heating furnace, then loosen the lifting device, and let the rods fall into the heating furnace. Due to the limitations of the lifting device, the entire process causes the rods to move noisily, and the mutual collision of the rods can easily cause damage to the surface of the rods and damage to the transfer device caused by the rods colliding with the transfer device. Therefore, there is an urgent need for a walking heating furnace for rods that can minimize the collision between the rods when transferring the rods. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a walking-beam heating furnace for rods, which can solve the problems of mutual collision of rods during plate transportation, which can easily cause damage to the surface of the rods and damage to the transportation device caused by the collision of rods with the transportation device.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a walking beam heating furnace for rods, comprising a ground and a walking beam assembly;

[0006] The stepper assembly is arranged on the ground, and the stepper assembly includes multiple roller one, multiple connecting parts one, multiple roller two, multiple ramp parts, connecting parts two, multiple guide columns, fixing parts, connecting rods, supporting parts, multiple guide holes and supporting frames. The multiple ramp parts are welded to the upper end of the ground, and the multiple roller twos roll along the inclined surfaces of the corresponding ramp parts respectively. The lower ends of the multiple connecting parts one are respectively connected to the corresponding roller two for rotation, and the upper ends of the multiple connecting parts one are respectively connected to the corresponding roller one for rotation, and the multiple connecting parts one are fixed on the connecting rod. The upper surfaces of the multiple rollers one are in rolling contact with the connecting part two, and the lower ends of the multiple guide columns are fixedly connected to the upper end of the connecting part two.

[0007] Preferably, the fixing member is fixed on the ground, and the fixing member is fixed to the upper end of the second connecting member.

[0008] Preferably, the plurality of guide holes are all formed on the fixing member, and the plurality of guide posts slide along the insides of the corresponding guide holes respectively.

[0009] Preferably, the plurality of guide posts are all against the support member, and the right end of the support member is connected to the output end of the linear motor.

[0010] Preferably, a plurality of rod-type steel materials are provided at the upper end of the support member, and the support frame is fixed on the fixing member.

[0011] Preferably, a plurality of grooves are provided on both sides of the support frame, and two ends of a plurality of rod-type steel materials are respectively clamped in the corresponding grooves.

[0012] Preferably, a heating furnace body is fixedly installed on the left side of the ground, and the entrance of the ground is lower than the position of the plurality of rod-type steel materials.

[0013] Preferably, a hydraulic sleeve is fixedly installed on the ground, a hydraulic push rod is installed inside the hydraulic sleeve, and the other end of the hydraulic push rod is connected to the connecting rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The walking beam heating furnace for bars has a support frame in the walking beam assembly, and a plurality of bar-type steels are placed inside the groove on the support frame, so as to avoid mutual collision between the bar-type steels during the transfer of the bar-type steels, thereby preventing the bar-type steels from being damaged, thus achieving the real meaning of "handle with care" and extending the service life of the components of the entire transfer device.

[0016] 2. The walking-beam heating furnace for the rod supports the support member to move up and down by moving a plurality of rollers at the bottom of the support member upward. The plurality of rollers roll to drive the support member to move upward, and the up and down movement is gentler, and the impact force is smaller and more evenly distributed, thereby ensuring that the support member with a longer size can move upward steadily.

[0017] 3. The walking beam heating furnace for rods is provided with a plurality of guide holes, and the plurality of guide holes respectively limit the up and down movement of the corresponding guide columns, so that the support member presents an up and down movement, that is, the slope movement formed by the plurality of rollers can be converted into an up and down movement, so as to better separate and control the movement of the plurality of rod-type steel materials on the support member.

[0018] 4. The walking-beam heating furnace for the rods is provided with a walking assembly, which can move the multiple rod-type steels on the upper end of the walking assembly to the inside of the left heating furnace body in a constant time manner. This can not only avoid the problem of excessive heating burden of the heating furnace body caused by too many rod-type steels inside the heating furnace body, but also, the constant time of unloading and taking materials can ensure that the heating time of some rod-type steels is almost consistent, thereby ensuring the quality of each batch of rod-type steels in the final heating and forming, which is more convenient for actual processing.

[0027] See also Figure 1-2 , the present invention provides a technical solution: a walking beam heating furnace for rods, comprising a ground 17 and a walking beam assembly;

[0028] The stepper assembly is arranged on the ground 17, and the stepper assembly includes multiple rollers 2, multiple connecting members 3, multiple rollers 4, multiple ramp members 5, connecting members 6, multiple guide columns 7, fixing members 8, connecting rod members 9, supporting members 13, multiple guide holes 14 and supporting frames 15. The multiple ramp members 5 are all welded to the upper end of the ground 17, and the multiple rollers 4 roll along the inclined surfaces of the corresponding ramp members 5 respectively. The lower ends of the multiple connecting members 3 are respectively connected to the corresponding rollers 4 for rotation, and the upper ends of the multiple connecting members 3 are respectively connected to the corresponding rollers 2 for rotation. The multiple connecting members 3 are all fixed on the connecting rod member 9, and the upper surfaces of the multiple rollers 2 are in rolling contact with the connecting member 2 6. The lower ends of the multiple guide columns 7 are all fixedly connected to the upper ends of the connecting member 2 6.

[0029] The fixing member 8 is fixed on the ground 17 , and the fixing member 8 is fixed on the upper end of the second connecting member 6 .

[0030] A plurality of guide holes 14 are formed on the fixing member 8 , and a plurality of guide posts 7 slide along the inside of the corresponding guide holes 14 .

[0031] The plurality of guide posts 7 are all against the support member 13 , and the right end of the support member 13 is connected to the output end of the linear motor 12 .

[0032] A plurality of rod-shaped steel materials 16 are disposed at the upper end of the support member 13 , and the support frame 15 is fixed on the fixing member 8 .

[0033] A plurality of grooves are formed on both sides of the support frame 15 , and two ends of a plurality of rod-shaped steel materials 16 are respectively clamped in the corresponding grooves.

[0034] The heating furnace body 1 is fixedly installed on the left side of the ground 17 , and the entrance of the ground 17 is lower than the position of the plurality of rod-shaped steel materials 16 .

[0035] A hydraulic sleeve 10 is fixedly installed on the ground 17 , a hydraulic push rod 11 is installed inside the hydraulic sleeve 10 , and the other end of the hydraulic push rod 11 is connected to the connecting rod 9 .

[0036] When it is necessary to step and load the rod-shaped steel material 16 into the interior of the heating furnace body 1;

[0037] First, the hydraulic sleeve 10 is started by an external power supply. The start of the hydraulic sleeve 10 drives the hydraulic push rod 11 to move. The movement of the hydraulic push rod 11 pushes the connecting rod 9 to move. The movement of the connecting rod 9 drives multiple connecting members 3 to move. The movements of the multiple connecting members 3 drive the corresponding rollers 2 4 to roll along the corresponding ramp members 5. At the same time, the movements of the multiple connecting members 3 drive the corresponding rollers 2 to move. The movement of the multiple rollers 2 drives the connecting member 2 6 to move upward. The upward movement of the connecting member 2 6 drives the multiple guide columns 7 to slide upward along the corresponding guide holes 14. The upward movement of the multiple guide columns 7 drives the support member 13 to move upward. The upward movement of the multiple support members 13 drives the multiple rod-type steels 16 at the upper end of the support member 13 to move upward. The two ends of the multiple rod-type steels 16 move upward to disengage from the grooves on the corresponding support frames 15.

[0038] Secondly, start the linear motor 12. The start of the linear motor 12 drives the support member 13 to move in the opposite direction. The movement of the support member 13 drives the multiple rod-type steels 16 on the support member 13 to move to a certain distance. The leftmost rod-type steel 16 on the support member 13 enters the interior of the heating furnace body 1, and the other rod-type steels 16 all step to the left by the distance of a groove on the support frame 15.

[0039] Finally, start the hydraulic sleeve 10. The start of the hydraulic sleeve 10 drives the hydraulic push rod 11 to move back to its original position. The movement of the hydraulic push rod 11 drives the connecting rod 9 to move. The movement of the connecting rod 9 drives multiple connecting parts 3 to move. The movement of multiple connecting parts 3 drives the corresponding rollers 2 4 to roll downward along the corresponding ramp parts 5. At the same time, the movement of multiple connecting parts 3 drives the corresponding rollers 2 to move downward. The downward movement of multiple rollers 2 drives the corresponding connecting rods 9 to move downward. The downward movement of the connecting rod 9 drives multiple guide columns 7 to move downward. The downward movement of multiple guide columns 7 drives the support 13 to move downward. The downward movement of the support 13 drives multiple rod-type steels 16 to move downward to the inside of the groove of the support frame 15. Then, start the linear motor 12. The start of the linear motor 12 drives the support 13 back to its original position.

[0040] By setting up a support frame 15 in the stepping assembly, a plurality of rod-type steel materials 16 are placed inside the groove on the support frame 15, thereby avoiding collision between the rod-type steel materials 16 during the transfer of the rod-type steel materials 16, thereby preventing the rod-type steel materials 16 from being damaged. This achieves the true meaning of "handle with care" and extends the service life of the components of the entire transfer device.

[0041] The support member 13 is supported to move up and down by having multiple rollers 2 at the bottom of the support member 13 move upward. The multiple rollers 2 drive the support member 13 to move upward in a rolling manner. The up and down movement is gentler, and the impact force is smaller and more evenly distributed, thereby ensuring that the longer support member 13 can move upward steadily.

[0042] By setting up a plurality of guide holes 14, the plurality of guide holes 14 respectively limit the up and down movement of the corresponding guide columns 7, so that the support member 13 can present an up and down movement, that is, the slope movement formed by the plurality of rollers 2 can be converted into an up and down movement, so as to better separate and control the movement of the plurality of rod-type steel materials 16 on the support member 13.

[0043] By setting up a stepping assembly, the stepping assembly can move the multiple rod-type steel materials 16 on the upper end of the stepping assembly to the inside of the left heating furnace body 1 in a constant time manner, which can not only avoid the problem of excessive heating burden of the heating furnace body 1 caused by too many rod-type steel materials 16 inside the heating furnace body 1, but also, the constant time of unloading and taking materials can ensure that the heating time of some rod-type steel materials 16 is almost consistent, thereby ensuring the quality of each batch of rod-type steel materials 16 that are finally heated and formed, which is more convenient for actual processing.
