Description

Technical Field

[0001] This utility model relates to the field of steel bar technology, specifically to a steel bar cutting device. Background Technology

[0002] Rebar refers to steel used in reinforced concrete and prestressed reinforced concrete, with a circular cross-section, sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars.

[0003] Currently, a rebar cutter is a tool used to cut rebar. It is an essential piece of equipment in rebar processing and is mainly used for cutting rebar to a fixed length in projects such as building construction, bridges, tunnels, power stations, and large-scale water conservancy projects. Compared with other cutting equipment, rebar cutters are lightweight, consume less energy, are reliable in operation, and are highly efficient. Therefore, in recent years, they have been widely adopted by mechanical processing and small steel rolling mills, playing an important role in various fields of national economic construction.

[0004] During the cutting and processing of steel bars, they are often discarded due to insufficient cutting precision. This is mostly caused by inaccurate manual placement or severe vibration during the cutting process, which causes the cutting position of the steel bars to shift, making the cut objects unusable and resulting in a large amount of material waste. This also causes inconvenience to the staff. Utility Model Content

[0011] Beneficial effects

[0012] This utility model provides a rebar cutting device. It has the following advantages: the rebar cutting device, through the cooperation of a cutter, a limiting device, a horizontal plate, an adjusting device, and a conveying device, can clamp and fix the rebar during cutting, thereby greatly reducing the problem of reduced cutting quality due to severe vibration during cutting.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] During the cutting and processing of steel bars, they are often discarded due to insufficient cutting precision. This is mostly due to inaccurate manual placement or violent vibration during the cutting process, which causes the cutting position of the steel bars to shift, making the cut objects unusable and resulting in a large amount of material waste. This also causes inconvenience to the staff.

[0022] In view of this, the present invention provides a rebar cutting device with the following advantages: the rebar cutting device, through the cooperation of a cutter, a limiting device, a horizontal plate, an adjusting device and a conveying device, can clamp and fix the rebar during cutting, thereby greatly reducing the problem of reduced cutting quality due to violent shaking during cutting, and can automatically carry out the rebar conveying work, eliminating the need for manual measurement and conveying by personnel, thus ensuring the cutting accuracy of the rebar and improving the cutting quality.

[0023] Example 1: By Figure 1 , 2 As shown in 3 and 4, a rebar cutting device includes a horizontal plate 1, with support legs 5 installed at the four corners of the bottom of the horizontal plate 1, a slide rail 9 installed on the top of the horizontal plate 1, a cutting table 6 installed on the top of the horizontal plate 1, a cutter 4 installed on the top of the cutting table 6, and two openings 10 machined on the top of the horizontal plate 1. The rebar cutting device also includes: a cooling device 2 installed below the horizontal plate 1; a limiting device 7 installed above the horizontal plate 1; a conveying device 8 installed below the horizontal plate 1; and an adjusting device 3 installed above the horizontal plate 1. The cooling device 2 can cool the cutting blade of the cutter 4, the limiting device 7 can clamp and limit the rebar, the conveying device 8 can convey the rebar through the limiting device 7 to limit the cutting length, and the adjusting device 3 can change the position and height of the cutter 4.

[0024] In the specific implementation process, it is worth noting that the cutter 4 is an existing cutting device. This case does not make any innovation or structural improvement to this part, and this is a well-known technology to those skilled in the art, so it will not be described in detail. Those skilled in the art should understand it in a broad sense. The cooling device 2 can cool down the cutter 4, the conveying device 8 can change the position of the limiting device 7, and thus the steel bar can be conveyed through the limiting device 7. The adjusting device 3 can change the height of the cutter 4, so that the cutter 4 can better complete the cutting work.

[0025] Specifically, when using this type of rebar cutting equipment, the operator first puts the rebar to be cut into the limiting device 7, and then turns on the external power supply of the conveying device 8. At this time, the conveying device 8 can convey a fixed length of rebar through the limiting device 7. At the same time, the operator turns on the control power supply of the adjusting device 3 and the cutter 4, and then the rebar can be cut. At the same time, the operator turns on the external power supply of the cooling device 2, and then the cooling device 2 can cool down the cutter 4.

[0026] Example 2: From Figure 1 , 2 As shown in section 3, the cooling device 2 includes: a water tank 204, installed at the bottom of the horizontal plate 1; a water pump 201, the model of which is not specifically limited as long as it meets the usage requirements, and is detachably connected to the inside of the water tank 204; a water pipe 202, connected to the output end of the water pump 201 and extending to the top of the horizontal plate 1, with the top of the water pipe 202 fixed to one side of the outer wall of the cutter 4; a filter screen 203, the mesh count of which is not specifically limited as long as it meets the usage requirements, and is installed inside the water tank 204; and a water inlet pipe 205, connected to the lower side of the water tank 204. External water can be supplied to the inside of the water tank 204 through the water inlet pipe 205. The water pump 201 can extract water from the inside of the water tank 204, transport it through the water pipe 202, and finally spray it onto the cutting position of the cutter 4. The used cooling water can flow back into the inside of the water tank 204 through the opening 10 and will also be filtered by the filter screen 203.

[0027] In the specific implementation process, it is worth noting that the filter screen 203 can filter the used coolant to prevent iron from entering the interior of the water tank 204 along with the coolant, thus ensuring the safe use of the water pump 201. The water pipe 202 is a flexible pipe that can be stretched and bent, and its specific material is not limited as long as it meets the usage requirements.

[0028] Specifically, based on the above embodiment one, when cutting steel bars, the worker turns on the external power supply of the water pump 201. The water pump 201 draws water from the water tank 204 and sprays it to the cutting position of the cutter 4 through the water pipe 202. The water pipe 202 can change with the position of the cutter 4. The opening 10 can introduce the cooled water into the water tank 204 for water resource recycling.

[0029] Example 3: From Figure 1 , 2 As shown in section 4, the limiting device 7 includes: two brackets 705, each positioned above the horizontal plate 1, with the bottom of the bracket 705 on the side furthest from the cutter 4 fixed to the top of the horizontal plate 1; two top plates 703, each mounted on the top of one of the two brackets 705; a first servo motor 701, model ECMA-E11320RS, detachably connected to the top of each of the two top plates 703; and two first threaded rods 706, each detachably connected to the output end of one of the two first servo motors 701, and connected to... The bearings are rotatably connected to the inner walls of the two top plates 703 respectively; two sleeves 704 are provided, each threadedly connected to the outer wall of the two first threaded rods 706; two clamping plates 708 are provided, each installed at the bottom of the two sleeves 704; multiple limiting rods 702 are provided, each installed at the top of the two clamping plates 708, and movably connected to the inner walls of the two top plates 703 respectively; a controller 707 is detachably connected to the bottom of the horizontal plate 1; wherein, the first servo motor 701 can drive the sleeves 704 to move the clamping plates 708 through the first threaded rods 706;

[0030] In the specific implementation process, it is worth noting that the first servo motor 701 can change the position of the clamping plate 708 through the first threaded rod 706, and then the clamping plate 708 can be used in conjunction with other components to clamp and limit the steel bar, so as to prevent the steel bar from shaking during cutting.

[0031] Specifically, based on the above embodiment one, when it is necessary to clamp and limit the rebar, the worker turns on the external power supply of the first servo motor 701. At this time, the first servo motor 701 drives the first threaded rod 706 to rotate. The first threaded rod 706 can change the position of the clamping plate 708 through the sleeve 704. As the position of the clamping plate 708 changes, the rebar can be clamped and limited.

[0032] Example 4: From Figure 1 , 2As shown in section 4, the conveying device 8 includes: a second servo motor 801, model ECMA-E11320RS, which is detachably connected to one side of the horizontal plate 1; a second threaded rod 802, which is rotatably connected to the lower part of the horizontal plate 1 via a bearing and is detachably connected to the output end of the second servo motor 801; and a slider 803, which is threadedly connected to the outer wall of the second threaded rod 802 and movably connected to the inner wall of the horizontal plate 1, with the upper part of the slider 803 slidably engaged with the outer wall of the slide rail 9; wherein, the second servo motor 801 can drive the second threaded rod 802 to change the position of the slider 803 on the outer wall of the slide rail 9;

[0033] In the specific implementation process, it is worth noting that the second servo motor 801 can change the position of the slider 803 through the second threaded rod 802, and then change the position of the limiting device 7 through the slider 803, so as to transport the steel bars.

[0034] Specifically, based on the above embodiments one, two and three, the operator turns on the external power supply of the second servo motor 801, which drives the second threaded rod 802 to rotate. The second threaded rod 802 can then drive the slider 803 to move along the outer wall of the slide rail 9. At this time, the slider 803 can change the position of the steel bar through the limiting device 7, thereby realizing the feeding operation.

[0035] Example 5: From Figure 1 , 2 As shown in section 3, the adjustment device 3 includes: four sleeve rods 301, all installed on the top of the horizontal plate 1; four electric push rods 302 (model TG-700), each installed inside one of the four sleeve rods 301; and a top plate 303, inserted into the four sleeve rods 301 and detachably connected to the output ends of the four electric push rods 302. The top of the top plate 303 is detachably connected to the top of the cutter 4. The electric push rods 302 can drive the top plate 303 to move along the inner wall of the sleeve rods 301, thereby changing the position and height of the cutter 4.

[0036] In the specific implementation process, it is worth noting that the electric push rod 302 can change the height of the cutter 4 through the top plate 303 so as to ensure that the cutter 4 can better complete the cutting work.

[0037] Specifically, based on the above embodiment one, when adjusting the position height of the cutter 4, the operator turns on the external power supply of the electric push rod 302, and the electric push rod 302 pushes the top plate 303 to move inside the sleeve rod 301, thereby changing the position height of the cutter 4 through the top plate 303.
