Description

Technical Field

[0001] The utility model relates to the field of aerated concrete equipment, in particular to a wax dipping device for a steel bar used in aerated concrete production. Background Art

[0002] During the preparation of autoclaved aerated concrete slabs, steel chisels are used to support the steel mesh cage to be inserted into the casting mold. When the steel mesh cage is solidified inside the blank by the slurry in the casting mold, the steel chisel is pulled out and then cleaned and dipped in wax to protect it.

[0003] The invention patent with Chinese patent application number 202210411426.0 discloses a wax dipping device, a control method and an aerated concrete production line, wherein the wax dipping device comprises: a wax dipping pool; a heating assembly, comprising a steam heating pipe, a steam inlet pipe and a steam outlet pipe, wherein the steam heating pipe is arranged at the bottom of the wax dipping pool, and the steam inlet pipe and the steam outlet pipe are both connected to the steam heating pipe; a first thermometer and a second thermometer, wherein the first thermometer is at least partially plugged into the wax liquid layer in the wax dipping pool, and the second thermometer is at least partially plugged into the water layer wax replenishing mechanism in the wax dipping pool, which is arranged above the wax dipping pool and is suitable for replenishing paraffin to the wax dipping pool. The wax dipping device of the present invention improves the heating efficiency, shortens the heat transfer path, reduces heat loss, and ensures the quality of wax dipping, and can replenish paraffin to the wax dipping pool in time to ensure the normal progress of the wax dipping process.

[0004] However, when the equipment is in use, the wax will not solidify immediately when the steel bar is removed from the wax immersion pool. Removing the steel bar at this time will cause the wax to drip around the wax immersion pool; waiting for the wax to solidify will affect the wax immersion efficiency. Utility Model Content

[0005] In view of the above problems, the utility model provides a wax dipping device for aerated concrete production, in which a cooling block that can move up and down is arranged inside the steel bar, and the cooling block is driven by a moving mechanism and a power mechanism. When the steel bar is moved out of the wax dipping pool, the cooling block and the steel bar produce relative movement, so that the cooling block always remains above the liquid level of the wax dipping pool. Therefore, after the steel bar is moved out of the liquid surface, the cooling block cools the steel bar so that the wax liquid solidifies quickly, thereby improving the wax dipping efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wax dipping device for steel bar used in aerated concrete production, comprising:

[0008] Waxing pool;

[0009] A support frame, wherein the support frame is movably arranged above the wax dipping pool;

[0010] Steel chisels, several groups of which are arranged vertically and horizontally and are detachably mounted on the support frame;

[0011] A cooling assembly, the cooling assembly comprising a movable groove coaxially provided inside the steel drill, a cooling block arranged inside the movable groove for vertical movement, a moving mechanism for driving the cooling block to move up and down, and a power mechanism installed on the support frame and driving a plurality of groups of the moving mechanisms to move synchronously;

[0012] The support frame drives several groups of the steel chisels to leave the wax immersion pool, and the power mechanism and the moving mechanism operate so that the cooling block is always located above the liquid level in the wax immersion pool and the relative positions of the two remain unchanged.

[0013] As an improvement, the cooling block includes a sliding block slidably disposed in the movable groove and a condensing water pipe surrounding the interior of the sliding block and communicating with an external cooling device.

[0014] As an improvement, the sliding block is made of copper.

[0015] As an improvement, the moving mechanism includes a lead screw coaxially arranged at the center position of the moving groove, a nut threadedly arranged on the lead screw and coaxially installed with the cooling block, a guide groove extending axially along the moving groove and opened on its inner wall, a guide block slidably arranged in the guide groove and fixedly installed on the outside of the cooling block, and a worm gear coaxially installed on the top end of the lead screw.

[0016] As an improvement, the power mechanism includes worms distributed along a longitudinal array and meshing with a worm wheel, two groups of support seats for supporting the worms and located at both ends thereof, a transmission pair for power-connecting several groups of the worms, and a power pair for driving any of the worms to rotate.

[0017] As an improvement, the transmission pair includes a sprocket coaxially mounted on one end of the worm and chains wound around the outside of a plurality of groups of the sprockets.

[0018] As an improvement, the power pair includes a motor mounting seat installed on the support seat, a reducer installed on the motor mounting seat, a servo motor installed on the reducer, and a coupling for dynamically connecting the reducer and the worm.

[0019] The beneficial effects of the utility model are:

[0020] (1) In the utility model, the support frame drives several groups of steel drills to move upward, and the steel drills leave the wax liquid surface. At the same time, under the action of the servo motor, the worm will rotate and drive the worm wheel to rotate, and then the lead screw will rotate and drive the slider and the nut to move relative to the steel drill, so that the slider and the nut remain unchanged relative to the wax liquid surface. The slider can cool the steel drill that leaves the wax liquid surface, so that the wax liquid attached to the steel drill can solidify quickly, so that the wax liquid will not drip, thereby improving the wax immersion efficiency;

[0021] (2) The material of the slider in the utility model is copper, which improves the thermal conductivity of the slider and makes the slider move more smoothly inside the steel drill, thereby improving the convenience of equipment use and further improving the wax dipping efficiency;

[0022] (3) The worm in the utility model extends laterally along the support frame, so that the steel chisel and the corresponding cooling assembly can be adjusted laterally along the support frame. After the adjustment is completed, the worm wheel and the worm are still in a mating state. For example, the distance between two adjacent groups of steel chisels can be adjusted to meet different processing requirements, thereby improving the applicability of the equipment.

[0023] In summary, the utility model has the advantages of simple structure and high wax impregnation efficiency, and is particularly suitable for the field of aerated concrete equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example:

[0035] like Figure 1 and Figure 2 As shown, a wax dipping device for steel bar used in aerated concrete production comprises:

[0036] Wax immersion pool 1;

[0037] A support frame 2, wherein the support frame 2 is movably disposed above the wax immersion pool 1;

[0038] Steel chisels 3, several groups of which are arranged vertically and horizontally and are detachably mounted on the support frame 2;

[0039] A cooling assembly 4, the cooling assembly 4 comprising a movable groove 40 correspondingly coaxially opened inside the steel drill 3, a cooling block 41 arranged inside the movable groove 40 for vertical movement, a moving mechanism 42 for driving the cooling block 41 to move up and down, and a power mechanism 43 installed on the support frame 2 and driving a plurality of groups of the moving mechanisms 42 to move synchronously;

[0040] The support frame 2 drives several groups of the steel chisels 3 to leave the wax immersion pool 1, and the power mechanism 43 and the moving mechanism 42 operate so that the cooling block 41 is always located above the liquid level in the wax immersion pool 1 and the relative positions of the two remain unchanged.

[0041] It should be noted that the support frame 2 can move up and down just above the wax immersion pool 1, thereby driving several groups of steel chisels 3 thereon to enter and leave the wax immersion pool 1, and the support frame 2 can also be moved away from above the wax immersion pool 1. The movement method and movement principle of the support frame 2 are both existing technologies, so they will not be described in detail in this utility model.

[0042] It should be further explained that the installation of the steel chisel 3 on the support frame 2 is a prior art, so it will not be described in detail in the present utility model.

[0043] Further, such as Figure 7 As shown, the cooling block 41 includes a slider 411 slidably disposed in the movable groove 40 and a condensing water pipe 412 surrounding the slider 411 and communicating with an external cooling device.

[0044] Furthermore, the slider 411 is made of copper.

[0045] It should be noted that the material of the slider 411 is copper, which can improve the thermal conductivity of the slider 411 , improve the cooling efficiency, and make the slider 411 move more smoothly in the moving groove 40 .

[0046] Further, such as Figure 5 and Figure 6 As shown, the moving mechanism 42 includes a lead screw 421 coaxially rotatably arranged at the center position of the moving groove 40, a nut 422 threadedly arranged on the lead screw 421 and coaxially installed with the cooling block 41, a guide groove 423 extending axially along the moving groove 40 and opened on the inner wall thereof, a guide block 424 slidably arranged in the guide groove 423 and fixedly installed on the outside of the cooling block 41, and a worm gear 425 coaxially installed on the top end of the lead screw 421.

[0047] It should be noted that the slider 411 is installed on the outer side of the nut 422 , and the guide block 424 is disposed on the slider 411 .

[0048] Further, such as Figure 3 and Figure 5As shown, the power mechanism 43 includes worms 431 distributed along a longitudinal array and meshing with the worm wheel 425, two groups of support seats 432 for supporting the worms 431 and located at both ends thereof, a transmission pair 433 for power connecting several groups of the worms 431, and a power pair 434 for driving any of the worms 431 to rotate.

[0049] It should be noted that the cooperation between the worm 431 and the worm wheel 425 has a self-locking function, which can effectively prevent the slider 411 from moving up and down.

[0050] It should be noted that the power pair 434 drives the worm 431 connected thereto to rotate, and then several groups of the worm 431 rotate simultaneously through the transmission pair 433, thereby driving the lead screw 421 to rotate, and the nut 422 and the slider 411 move in the movable groove 40.

[0051] It is also necessary to explain that, in the process of the steel drill 3 moving upward, the nut 422 and the slider 411 move downward in the moving groove 40, so that the moving speeds of the nut 422 and the slider 411 are adapted to the moving speed of the steel drill 3, so that the slider 411 is always kept consistent with the liquid level of the wax liquid, and the slider 411 is located above the liquid level of the wax liquid, so that the slider 411 cools the steel drill 3 that leaves the liquid wax surface, which is beneficial to the solidification of the wax liquid.

[0052] Further, such as Figure 4 As shown, the transmission pair 433 includes a sprocket 4331 coaxially mounted on one end of the worm 431 and chains 4332 wound around the outside of a plurality of groups of the sprockets 4331 .

[0053] Further, such as Figure 3 As shown, the power pair 434 includes a motor mounting base 4341 mounted on the support base 432, a reducer 4342 mounted on the motor mounting base 4341, a servo motor 4343 mounted on the reducer 4342, and a coupling 4344 for dynamically connecting the reducer 4342 and the worm 431.

[0054] It should be noted that the rotation speed of the servo motor 4343 is controllable. Using the servo motor 4343 as a power source makes the moving speed of the slider 411 more compatible with the moving speed of the steel drill 3, further improving the cooling effect of the steel drill 3.

[0055] It should be further explained that the model of the servo motor 4343 is hg-kn43j_-s100, the brand is Mitsubishi, and the model of the reducer 4342 is NB-060-L1-5 helical gear precision planetary reducer, the brand is Senad.

[0056] Working process:

[0057] The wax immersion pool 1 contains wax liquid, and the support frame 2 drives several groups of the steel bar 3 to move downward so that the steel bar 3 extends into the wax liquid, and then the support frame 2 drives the steel bar 3 to move upward. At this time, the servo motor 4343 drives the worm 431 to rotate, and under the action of the chain 4332 and several groups of the sprockets 4331, several groups of the worm 431 rotate synchronously, thereby driving several groups of the worm wheels 425 to rotate, and the worm wheels 425 drive the lead screw 421 to rotate, thereby causing the nut 422 and the slider 411 to move downward in the movable groove 40, and the steel bar 3 gradually moves out of the wax liquid, and the slider 411 always remains above the wax liquid surface, and the slider 411 cooperates with the condensation water pipe 412 to cool the steel bar 3, so that the wax liquid attached to the steel bar 3 solidifies quickly.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
