Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing devices, and more specifically, it relates to a novel steel bar cutting machine. Background Art

[0002] A steel bar cutting machine is a tool used to cut steel bars. It is generally divided into fully automatic steel bar cutting machines and semi-automatic steel bar cutting machines. The fully automatic, also called electric cutting machine, converts electric energy into kinetic energy through a motor to control the cutting edge of the cutter to achieve the effect of cutting steel bars, while the semi-automatic one is manually controlled to cut the steel bars. In terms of efficiency, the electric steel bar cutting machine is many times faster than manual work. It is suitable for cutting various ordinary carbon steels, hot-rolled round steels, threaded steels, flat steels, and square steels in construction projects. Among them, the most widely used fully automatic cutting machine is the portable steel bar cutting machine. Compared with other cutting equipment, it has the characteristics of light weight, low energy consumption, reliable operation, and high efficiency. Therefore, it has played an important role in various fields of national economic construction in recent years. The principle is that the blade and the knife seat are intertwined and form a right angle with the steel bar, and the cutting surface of the steel bar is achieved by moving the blade.

[0003] When recycling scrap steel bars, a fully automatic steel bar cutting machine is required to cut them into particles. When in use, the steel bars are inserted vertically downward into the feed port, and the scrap steel bars naturally fall into the cutting box. The ends of the steel bars are automatically aligned on the bottom plane of the cutting box, and the blade continues to move back and forth for automatic cutting, and the cut steel bar particles continue to slide out. However, the recycled scrap steel bars are bent into balls. Unlike straight scrap steel bars, they are too large to be directly stuffed into the feed port. They need to be manually sorted and then semi-automatically cut into smaller steel bar ends for feeding and cutting, which affects the efficiency of steel bar cutting.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a new type of steel bar cutting machine. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a novel steel bar cutting machine.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the new steel bar cutting machine comprises a cutting box, a machine box and a compression feeding mechanism, wherein the machine box is arranged beside the cutting box, and the compression feeding mechanism is connected to the inside of the cutting box, and is used to squeeze and reduce the larger steel bar mass and feed it into the cutting box;

[0007] The compression feeding mechanism comprises a feeding bin, which is a V-shaped structure with upper and lower openings, wherein the end with a larger opening upward is a feeding end, and the end with a smaller opening downward is a discharging end, and the discharging end of the feeding bin is mounted on the cutting box and communicated with the inside of the cutting box;

[0008] A V-shaped extrusion roller group is installed in the upper material bin. The V-shaped extrusion rollers are mirror-symmetrical on the left and right and are arranged in parallel along the inclined surface of the upper material bin. The V-shaped extrusion roller group forms an extrusion opening in the gap in the vertical direction. The extrusion opening gradually converges downward in the vertical direction to achieve the effect of gradually squeezing the steel bar ball to reduce its volume.

[0009] Preferably, the surface of the V-shaped extrusion roller group is provided with hooking teeth to increase the gripping force to achieve the effect of continuously transporting the steel bar mass downward.

[0010] Preferably, the V-shaped squeezing roller group is connected to the output shaft of the rolling motor so that the V-shaped squeezing roller group can be braked by the rolling motor, and a transmission chain is installed between the V-shaped squeezing roller groups for transmission.

[0011] Preferably, an auxiliary extrusion assembly is also installed in the upper silo, and the auxiliary extrusion assembly includes a mounting rod and a sleeve. The mounting rod is installed on the inner wall of the upper silo, and a sleeve is movably sleeved on the mounting rod. The sleeve is used to form passive rolling from both sides of the extrusion port to assist feeding.

[0012] Preferably, a knife holder is installed in the cutting box, and a cutting knife is slidably installed in the cutting box for cutting the steel bars.

[0013] Preferably, a transmission assembly is installed in the chassis for braking the cutter, and the transmission assembly includes a rack for mounting the cutter, a running gear is meshed on the rack, and the running gear is mounted on a gear set, and a cutting motor output shaft is mounted on the gear set.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, a V-shaped extrusion roller group is provided to form an extrusion port that gradually closes downward. A hooking and pulling tooth that can hold the steel bar group and make the steel bar group continuously move downward and squeeze it can squeeze a large steel bar group into a smaller size and transport it to the cutting box for cutting. There is no need to cut the steel bar group in advance, thereby solving the problem that the recycled scrap steel bars are bent into a group. Unlike straight scrap steel bars, they are too large to be directly stuffed into the material guide port. They need to be manually sorted and then semi-automatically cut into smaller steel bar ends for feeding and cutting, which affects the efficiency of steel bar cutting.

[0016] 2. In the utility model, by setting up an auxiliary extrusion component, when the steel ball is squeezed by the V-shaped extrusion roller group to reduce its volume and is continuously transported downward, the sleeve can provide a resistance surface from both sides of the extrusion port, and the sleeve will be pulled and rotated by the steel bar, avoiding the direct contact between the steel bar and the inner wall of the upper bin to generate huge friction, thereby improving the feeding efficiency of the steel bar.

[0031] like Figure 1-3 As shown, a new type of steel bar cutting machine includes a cutting box 1, a chassis 2 and a compression feeding mechanism 3, wherein the chassis 2 is arranged beside the cutting box 1, and the compression feeding mechanism 3 is connected to the inside of the cutting box 1, and is used to squeeze and reduce a large steel bar mass to feed it into the cutting box 1;

[0032] The compression feeding mechanism 3 includes a loading bin 31, which is a V-shaped structure with upper and lower openings, wherein the end with a larger opening upward is the feeding end, and the end with a smaller opening downward is the discharging end. The discharging end of the loading bin 31 is installed on the cutting box 1 and is connected to the inside of the cutting box 1. A large steel ball is placed in the feeding end of the loading bin 31, and the feeding end with a larger opening can support a large steel ball;

[0033] The V-shaped squeezing roller set 32 ​​is connected to the output shaft of the rolling motor 35 so as to brake the V-shaped squeezing roller set 32 ​​through the rolling motor 35, and a transmission chain 34 is installed between the V-shaped squeezing roller sets 32 for transmission;

[0034] A V-shaped extrusion roller group 32 is installed in the upper bin 31. The V-shaped extrusion rollers are mirror-symmetrical and arranged in parallel along the inclined surface of the upper bin 31. The V-shaped extrusion roller group 32 forms an extrusion opening in the gap in the vertical direction. The extrusion opening gradually closes downward in the vertical direction to achieve the effect of gradually squeezing the steel bar mass to reduce its volume.

[0035] As attached Figure 1 As shown, the V-shaped extrusion roller group 32 transmission chain 34 is divided into two groups on the left and right, and the transmissions on the same side have the same rotation direction and speed. Figure 2 As shown, the V-shaped squeezing roller group 32 is composed of three pairs of squeezing rollers with large, medium and small diameters from top to bottom. The squeezing rollers on the same horizontal line have the same diameter. To achieve the effect of squeezing and transporting downward, the squeezing roller on the left rotates clockwise, and the squeezing roller on the right rotates counterclockwise.

[0036] The surface of the V-shaped extrusion roller group 32 is provided with hooking teeth 33 to increase the gripping force to achieve the effect of continuously transporting the steel bar group downward. When the hooking teeth 33 rotate into the extrusion port, they press the bent steel bar to drive the steel bar downward. When they rotate out of the extrusion port and face the inner wall of the upper hopper 31, the hooking teeth 33 turn away from the steel bar surface, and the next group of hooking teeth 33 on the same extrusion roller or the hooking teeth 33 on the next group of extrusion rollers continue to press the steel bar downward.

[0037] An auxiliary extrusion assembly 4 is also installed in the upper bin 31. The auxiliary extrusion assembly 4 includes a mounting rod 41 and a sleeve 42. The mounting rod 41 is installed on the inner wall of the upper bin 31. The mounting rod 41 is movably sleeved with the sleeve 42. The sleeve 42 is used to form passive rolling from both sides of the extrusion port to assist feeding.

[0038] When the extrusion rollers pass through the extrusion opening formed between them and continuously squeeze the steel bar mass downward, the steel bars on both sides of the extrusion opening will at most rub against the inner wall of the upper bin 31 without being squeezed at all. The sleeve 42 is provided to continuously pull the steel bars downward to rotate, thus avoiding direct friction with the wall of the upper bin 31 and causing wear, and also speeding up the discharging speed of the steel bars.

[0039] A transmission assembly 5 is installed in the chassis 2 for braking the cutter 7. The transmission assembly 5 includes a rack 52 for mounting the cutter 7. A running gear 51 is meshed on the rack 52. The running gear 51 is mounted on a gear set 53. The output shaft of a cutting motor 54 is mounted on the gear set 53.

[0040] The cutting motor 54 is braked, and the gear set 53 is transmitted to the running gear 51, and the running gear 51 drives the rack 52 to make a linear reciprocating motion;

[0041] A knife holder 6 is installed in the cutting box 1, and a cutter 7 is also slidably installed in the cutting box 1 for cutting steel bars;

[0042] When the steel bar falls into the cutting box 1, the rack 52 drives the cutter 7 forward to push the steel bar against the knife seat 6 to cut the steel bar, and the rack 52 drives the cutter 7 back again, and the compression feeding mechanism 3 continuously squeezes and transports the steel bar downward, thereby achieving the technical effect of continuous cutting;

[0043] Therefore, by setting a V-shaped squeezing roller group 32, an squeezing port that gradually closes downward is formed, and a hooking and pulling tooth 33 that can hold the steel bar group and make the steel bar group continuously move downward and squeeze it is set on the squeezing roller group. The steel bar group with a larger volume can be squeezed into a smaller size and transported to the cutting box 1 for cutting, without cutting the steel bar group in advance, thereby solving the problem that the recycled scrap steel bars are bent into a ball, which is different from the straight scrap steel bars. The volume is too large to be directly stuffed into the material guide port, and it needs to be manually sorted and then semi-automatically cut into smaller steel bar ends for feeding and cutting, which affects the efficiency of steel bar cutting;

[0044] Therefore, by setting up an auxiliary extrusion component 4, when the steel ball is squeezed by the V-shaped extrusion roller group 32 to reduce its volume and continuously transported downward, the sleeve 42 can provide a resistance surface from both sides of the extrusion port, and the sleeve 42 will be pulled by the steel bar to rotate, thereby avoiding the steel bar directly contacting the inner wall of the upper bin 31 to generate huge friction, thereby improving the feeding efficiency of the steel bar.

[0045] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
