Description

Technical Field

[0001] This application relates to the technical field of aerated concrete cutting equipment, and particularly relates to a cutting machine that facilitates improving the flatness of aerated concrete products. Background Art

[0002] Aerated concrete is a lightweight porous silicate product made from siliceous materials (such as sand, fly ash, and silicon-containing tailings) and calcareous materials (such as lime and cement) as the main raw materials, admixed with a foaming agent (aluminum powder), and through processes such as batching, mixing, casting, pre-curing, cutting, autoclaving, and curing. Because it contains a large number of uniform and small pores after foaming, it is named aerated concrete. Its production process includes multiple steps. After the raw materials are mixed and cast, they need to be pushed into the initial curing chamber for gas generation and initial setting. When the initial setting is completed, cutting equipment is required to cut it into several blocks of material blocks that meet the predetermined size, and then autoclaving treatment is carried out to make it completely solidify to reach the designed strength.

[0003] In the prior art, a general cutting machine uses a cutting wire as a tool to perform vertical cutting on wet billets. Its cutting principle is to generate a large pressure with a smaller contact area of the wire, and then achieve cutting, which is the same as the cutting principle of a normal tool, that is, forcing an object to separate by applying a large pressure within the contact range. This cutting method will apply a large shear force to the contact surface during cutting, easily causing the wet billet that is not fully coagulated to deform in the direction of the force movement, resulting in poor flatness of the final cutting surface. Therefore, in view of the above problems, a cutting machine that facilitates improving the flatness of aerated concrete products is proposed. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, this application provides a cutting machine that facilitates improving the flatness of aerated concrete products, overcomes the deficiencies of the prior art, and aims to solve the problem that general equipment for aerated concrete cutting is prone to deformation of the cutting surface due to a unidirectional cutting force during operation and cannot ensure the flatness of the cutting surface.

[0005] To achieve the above object, this application provides the following technical solutions:

[0006] A cutting machine that facilitates improving the flatness of aerated concrete products, including a base. On both sides of the upper end surface of the base, a number of rows of cutting gantries are fixedly arranged. The cutting gantry includes two driving columns arranged oppositely. A transverse driving mechanism is connected to the driving columns. The transverse driving mechanism includes a connecting extension arm. The front end of the connecting extension arm is fixedly connected with a motor fixing shell. A second driving motor is fixedly arranged inside the motor fixing shell. The output shaft of the second driving motor is fixedly connected with a cable reel. A groove is formed in the middle of the cable reel and an end connecting wire is fixedly wound in the groove. One end of the end connecting wire far from the cable reel is fixedly connected with a wire saw.

[0007] By adopting the above technical solution, the cutting method of vertically cutting the wet blank can be replaced by the cutting method of horizontally sawing the wet blank. Specifically, the second driving motors on both sides drive the cable reels to rotate synchronously in the same forward direction, and then rotate synchronously in the opposite direction at a certain interval, so that the wire saw fixedly connected to the upper end of the wire can move left and right repeatedly, realizing the sawing effect on the wet blank. Since this method does not apply too much shear force to the cutting surface at one time and the forces applied to the cutting surface when the wire saw moves left and right once can cancel each other out to a certain extent, it is not easy to cause deformation of the cutting surface, and the flatness of the cutting surface can be ensured. At the same time, the driving column can drive the entire horizontal driving mechanism fixedly connected to it to move straight up and down, and there will be no situation of the cutting surface being inclined, which can also play a role in ensuring the flatness of the cutting surface.

[0008] As a preferred technical solution of the present application, a first mounting cover is fixedly covered on the front end surface of the second driving motor, a first encoder is fixedly installed in the first mounting cover, and the rotating shaft of the first encoder is fixedly connected to the center of the front end surface of the cable reel.

[0009] By adopting the above technical solution, the rotation information of the second driving motor can be obtained by the first encoder, so as to facilitate adjusting the second driving motors on both sides to work synchronously and avoid the situation of the wire saw being loose or over-tightened.

[0010] As a preferred technical solution of the present application, a through hole for the end connecting wire to pass through is opened on the first mounting cover.

[0011] By adopting the above technical solution, it can be avoided that the first mounting cover interferes with the winding and unwinding of the end connecting wire on the cable reel.

[0012] As a preferred technical solution of the present application, the driving column includes a first driving motor fixedly arranged in the base and a columnar cylinder fixedly arranged on the upper end surface of the base. A sliding block is slidably arranged in the columnar cylinder. The output shaft of the first driving motor is fixedly connected with a lead screw. The lead screw passes through the middle of the sliding block and is threadedly connected with it. The end of the connecting extension arm is fixedly connected with the sliding block.

[0013] By adopting the above technical solution, the first driving motor can drive the lead screw to rotate. Under the meshing action of the thread, the sliding block is driven to move up and down in the vertical direction, so as to drive the horizontal driving mechanism fixedly connected to it to move up and down to complete the cutting work of the entire cutting surface.

[0014] As a preferred technical solution of the present application, an end bearing is embedded in the top plate of the columnar cylinder. The outer ring of the end bearing is fixedly connected with the top plate of the columnar cylinder, and the lead screw is fixedly connected with the inner ring of the end bearing.

[0015] By adopting the above technical solution, it is possible to play a role in restraining and supporting the end of the lead screw while not interfering with its normal rotation.

[0016] As a preferred technical solution of the present application, a through chute is provided in the middle of the front side plate of the columnar cylinder, and the connecting extension arm is slidably arranged in the chute.

[0017] By adopting the above technical solution, it is possible to provide the necessary conditions for the fixed connection between the connecting extension arm and the sliding block.

[0018] As a preferred technical solution of the present application, a second mounting cover is fixedly covered on the upper end surface of the top plate of the columnar cylinder, a second encoder is fixedly installed in the second mounting cover, and the rotating shaft of the second encoder is fixedly connected to the center of the upper end surface of the lead screw.

[0019] By adopting the above technical solution, it is possible to obtain the rotation information of the first driving motor with the second encoder, so as to facilitate the adjustment of the sliding speeds of the two sliding blocks on both sides, so as to control the vertical movement speed of the wire saw, and avoid applying a large shear force to the cutting surface during the cutting process due to too fast speed, resulting in deformation of the cutting surface.

[0020] As a preferred technical solution of the present application, two symmetrically arranged slide rails are fixedly arranged on the upper end surface of the base, and a reinforcing plate is fixedly arranged at a position directly below the slide rails inside the base.

[0021] By adopting the above technical solution, it is possible to allow the structure with wet billets placed on it to move along the slide rails to complete the cutting work, and the reinforcing plate can share the vertical load transmitted from the slide rails, avoiding the compression deformation of the top plate of the base.

[0022] The beneficial effects of the present application: It is possible to replace the vertical cutting method with a horizontal sawing method for wet billets. Specifically, the horizontal driving mechanism can pull the wire saw to move left and right repeatedly to achieve the sawing effect on the wet billets. Since this method does not apply too large a shear force to the cutting surface at one time and the forces applied to the cutting surface when the wire saw moves left and right once can cancel each other out to a certain extent, it is not easy to cause deformation of the cutting surface and can ensure the flatness of the cutting surface;

[0023] At the same time, the driving column can drive the entire horizontal driving mechanism fixedly connected thereto to move straight up and down, and there will be no situation where the cutting surface is inclined, which can also play a role in ensuring the flatness of the cutting surface.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Referring to Figures 1-3 , a cutting machine for facilitating the improvement of the flatness of aerated concrete products, including a base 1. On both sides of the upper end surface of the base 1, a number of rows of cutting gantries 2 are fixedly arranged. The cutting gantry 2 includes two oppositely arranged driving columns 21. A transverse driving mechanism 3 is connected to the driving column 21. The transverse driving mechanism 3 includes a connecting extension arm 31. The front end of the connecting extension arm 31 is fixedly connected with a motor fixing shell 32. A second driving motor 33 is fixedly arranged in the motor fixing shell 32. The output shaft of the second driving motor 33 is fixedly connected with a cable reel 34. A groove is formed in the middle of the cable reel 34 and an end connecting steel wire 35 is fixedly wound in the groove. One end of the end connecting steel wire 35 away from the cable reel 34 is fixedly connected with a wire saw 4. By adopting the above technical solution, the cutting method of horizontally sawing wet blanks can be used to replace the cutting method of vertically cutting, so as to improve the flatness of the cutting surface;

[0031] Specifically, the second drive motors 33 on both sides drive the cable reels 34 to rotate synchronously in the same forward direction, and then rotate synchronously in the opposite direction at a certain interval, so that the hacksaw 4 fixedly connected to the upper end thereof by the steel wire 35 can move left and right repeatedly, realizing the sawing effect on the wet blank. Since this method does not apply too large a shearing force to the cutting surface at one time and the forces applied to the cutting surface when the hacksaw 4 moves left and right once can cancel each other out to a certain extent, it is not easy to cause deformation of the cutting surface, and the flatness of the cutting surface can be ensured. At the same time, the drive column 21 can drive the transverse drive mechanism 3 fixedly connected thereto to move straight up and down, and there will be no situation where the cutting surface is inclined, which can also play a role in ensuring the flatness of the cutting surface.

[0032] Refer to Figure 4 , a first mounting cover 51 is fixedly covered on the front end face of the second drive motor 33. A first encoder 5 is fixedly installed in the first mounting cover 51. The rotating shaft of the first encoder 5 is fixedly connected to the center of the front end face of the cable reel 34. By adopting the above technical solution, the rotation information of the second drive motor 33 can be obtained by the first encoder 5, so as to facilitate adjusting the second drive motors 33 on both sides to work synchronously and avoid the situation of the hacksaw 4 being slack or over-tightened. In addition, a through hole through which the end connecting wire 35 can pass is opened on the first mounting cover 51. This structural form can avoid interfering with the winding and unwinding of the end connecting wire 35 on the cable reel 34 due to the set first mounting cover 51.

[0033] Refer to Figures 2-3 , the drive column 21 includes a first drive motor 211 fixedly arranged in the base 1 and a cylindrical barrel 212 fixedly arranged on the upper end face of the base 1. A sliding block 213 is slidably arranged in the cylindrical barrel 212. The output shaft of the first drive motor 211 is fixedly connected to a lead screw 214. The lead screw 214 passes through the middle of the sliding block 213 and is threadedly connected thereto. The end of the connecting extension arm 31 is fixedly connected to the sliding block 213. By adopting the above technical solution, the first drive motor 211 can be used to drive the lead screw 214 to rotate. Under the meshing action of the thread, the sliding block 213 is driven to move up and down in the vertical direction, so as to drive the transverse drive mechanism 3 fixedly connected thereto to move up and down to complete the cutting work of the entire cutting surface.

[0034] Refer to Figure 3 , an end bearing 215 is embedded in the top plate of the cylindrical barrel 212. The outer ring of the end bearing 215 is fixedly connected to the top plate of the cylindrical barrel 212, and the lead screw 214 is fixedly connected to the inner ring of the end bearing 215. This structural form can play a role in restraining and supporting the end of the lead screw 214, and at the same time will not prevent its normal rotation. In addition, a through groove 216 is opened in the middle of the front side plate of the cylindrical barrel 212, and the connecting extension arm 31 is slidably arranged in the through groove 216, which can provide necessary conditions for the fixed connection between the connecting extension arm 31 and the sliding block 213.

[0035] Referring to Figure 3 Figure 3 , a second mounting cover 61 is fixedly covered on the upper end surface of the top plate of the columnar cylinder 212. A second encoder 6 is fixedly installed in the second mounting cover 61. The rotating shaft of the second encoder 6 is fixedly connected to the center of the upper end surface of the lead screw 214. By adopting the above technical solution, the rotation information of the first driving motor 211 can be obtained by the second encoder 6, so as to facilitate adjusting the sliding speeds of the two sliding blocks 213, so as to control the vertical movement speed of the wire saw 4, and avoid applying a large shearing force to the cutting surface during cutting due to too fast speed, resulting in deformation of the cutting surface.

[0036] Referring to Figures 1-2 Figures 1-2 , two symmetrically arranged slide rails 11 are fixedly arranged on the upper end surface of the base 1. A reinforcing plate 12 is fixedly arranged at a position directly below the slide rails 11 inside the base 1. By adopting the above technical solution, a structure with wet blanks placed thereon can be allowed to move along the slide rails 11 to complete the cutting work, and the reinforcing plate 12 can share the vertical load transmitted from the slide rails 11, avoiding compression deformation of the top plate of the base 1.

[0037] Working principle: This equipment can replace the vertical cutting method with a horizontal cutting method for wet blanks. Specifically, it is manifested that the second driving motors 33 on both sides drive the cable reels 34 to rotate synchronously and in the same forward direction, and then rotate synchronously and in the opposite direction at a certain interval, so that the wire saw 4 fixedly connected to the upper end of the wire 35 can move left and right repeatedly, realizing the sawing effect on the wet blank. Since this method does not apply too large a shearing force to the cutting surface at one time and the forces applied to the cutting surface when the wire saw 4 moves left and right once can offset each other to a certain extent, it is not easy to cause deformation of the cutting surface and can ensure the flatness of the cutting surface;

[0038] During horizontal cutting, the first driving motor 211 drives the lead screw 214 to rotate. Under the meshing action of the threads, the sliding block 213 is driven to move up and down along the vertical direction, so as to drive the horizontal driving mechanism 3 fixedly connected thereto to move up and down to complete the cutting work of the entire cutting surface. The above movement form can ensure that the whole horizontal driving mechanism 3 moves straight up and down during the movement process, without the situation of the cutting surface being inclined, and can also play a role in ensuring the flatness of the cutting surface;

[0039] In addition, the rotation information of the second drive motor 33 can be obtained by the first encoder 5, so as to facilitate the adjustment of the second drive motors 33 on both sides to work synchronously, avoiding the situation of the wire saw 4 being slack or over-tightened. At the same time, the rotation information of the first drive motor 211 can be obtained by the second encoder 6, so as to facilitate the adjustment of the sliding speeds of the sliding blocks 213 on both sides, so as to control the vertical movement speed of the wire saw 4, avoiding applying a large shearing force to the cutting surface during the cutting process due to too fast speed, resulting in the deformation of the cutting surface.

[0040] The foregoing is only the preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
