Description

Technical Field

[0001] This utility model relates to the field of bar and wire rolling technology, and in particular to a clamping device for bar and wire processing. Background Technology

[0002] In the nation's total steel production, bar and wire rod account for 40% of the total output. Bar and wire rod have a wide range of applications; aside from rebar and wire rod used directly as finished products in construction, they generally require further processing to become finished products. Because the rolled bars and wire rods are long and require long cutting lengths, they first need to be segmented and cut to high precision before finishing. When processing bars and wire rods in batches, clamps are used to hold them in place; however, existing clamps are prone to rotation during bar and wire rod cutting, resulting in insufficient cutting surface and precision.

[0003] For example, a clamping device for bar and wire processing disclosed in Chinese patent literature (publication number: CN212886235U) improves the cutting accuracy of bars and wires by setting upper and lower pads on the upper and lower frames that contact the bar and wire respectively, and by putting a protective rubber sleeve on the screw that contacts the bar and wire.

[0004] However, in actual batch processing scenarios, the bars and wires that are in direct contact with the gaskets on the outside can obtain relatively firm restraint, thus ensuring basic cutting accuracy during cutting. However, for the bars and wires located at the center of the stack, since they are surrounded by other bars and wires, they cannot obtain the direct and stable support and restraint from the gaskets during processing and cutting, unlike the outer bars and wires. Once the cutting equipment is started, the bars and wires are impacted by the cutting force. The bars and wires located in the middle are very prone to displacement and shaking due to uneven force. This instability will not only cause burrs, unevenness and other defects on the cutting surface of the bars and wires, affecting their surface quality, but may also cause deviations in the cutting dimensions, which are far from the preset accuracy requirements. Ultimately, this greatly reduces the overall processing quality and makes it difficult to meet the needs of high-precision processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor clamping stability during bar and wire processing, which leads to reduced processing quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for bar and wire processing, comprising a fixed base, a synchronous clamping mechanism provided at the upper end of the fixed base, and the synchronous clamping mechanism comprising guide rods, a plurality of guide rods being arranged in a rectangular array and fixedly connected to the upper end of the fixed base, and fixed clamping platforms arranged in a linear array being fixedly connected to the outside of the plurality of guide rods, wherein the lower end of one of the fixed clamping platforms is in contact with the upper end of the fixed base, and a first V-shaped clamping groove arranged in a linear array is provided at the upper end of the fixed clamping platform, and a first anti-slip pad is fixedly connected to the inner wall of the first V-shaped clamping groove;

[0007] Several guide rods are movably sleeved with movable clamping platforms arranged in a linear array. The lower end of the movable clamping platform is provided with a second V-shaped clamping groove arranged in a linear array. The inner wall of the second V-shaped clamping groove is fixedly connected with a second anti-slip pad. Fixed blocks are fixedly connected to both sides of the movable clamping platform in a symmetrical arrangement. A synchronization block is fixedly connected to one side of each of the fixed blocks.

[0008] A top plate is fixedly connected to the upper end of several guide rods. A hydraulic cylinder is fixedly installed on the upper end of the top plate. One end of the piston rod of the hydraulic cylinder passes through the top plate and is fixedly connected to the upper end of one of the movable clamping platforms.

[0009] The upper end of the fixed base is provided with a guide slope, the upper end of the fixed base is provided with a moving groove, and a servo motor is fixedly installed on the front of the fixed base.

[0010] The output shaft of the servo motor is fixedly mounted with a lead screw via a coupling, and one end of the lead screw passes through and extends into the interior of the moving slot.

[0011] One end of the lead screw is rotatably connected to the inner rear wall of the moving groove via a bearing. A threaded block is threadedly connected to the outside of the lead screw, and the outside of the threaded block is slidably connected to the inner wall of the moving groove.

[0012] A pointer is fixedly connected to the upper end of the threaded block, and a column is fixedly connected to the upper end of the threaded block.

[0013] An adjusting baffle is fixedly connected to one side of the column.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the synchronous clamping mechanism enables the simultaneous clamping and fixing of batches of bar and wire materials, which not only improves processing efficiency but also prevents loosening during processing. Furthermore, by adjusting the adjustment baffle, the cutting length of the bar and wire materials can be quickly limited, further improving the cutting efficiency of the bar and wire materials.

[0022] Example

[0023] like Figure 1-4 As shown, a clamping device for bar and wire processing includes a fixed base 1, which serves as a solid foundation for the entire device and provides stable support for numerous subsequent components.

[0024] A synchronous clamping mechanism is provided at the upper end of the fixed base 1, and the synchronous clamping mechanism includes guide rods 2. Several guide rods 2 are arranged in a rectangular array and are fixedly connected to the upper end of the fixed base 1. Fixed clamping platforms 21 arranged in a linear array are fixedly connected to the outside of several guide rods 2. The lower end of one of the fixed clamping platforms 21 contacts the upper end of the fixed base 1. The upper end of the fixed clamping platform 21 is provided with a first V-shaped clamping groove arranged in a linear array. It can better fit the circular cross section of the bar wire and provide stable lateral support force. A first anti-slip pad 22 is fixedly connected to the inner wall of the first V-shaped clamping groove. Its material is usually rubber or polyurethane material with high friction coefficient, wear resistance and not easy to damage the surface of the bar wire.

[0025] Several guide rods 2 are movably sleeved with movable clamping platforms 23 arranged in a linear array. This design allows the movable clamping platforms 23 to be flexibly raised and lowered under the guidance of the guide rods 2, so as to achieve precise clamping of the bar wire.

[0026] The lower end of the movable clamping platform 23 is provided with a second V-shaped clamping groove arranged in a linear array. The inner wall of the second V-shaped clamping groove is fixedly connected with a second anti-slip pad 24. The two sides of the movable clamping platform 23 are fixedly connected with symmetrically distributed fixing blocks 25. Each side of several fixing blocks 25 is fixedly connected with a synchronization block 26. These fixing blocks 25 act as bridges, connecting and transmitting forces. Through the coordinated linkage between the synchronization blocks 26, it is ensured that several movable clamping platforms 23 can perform lifting and lowering operations in a uniform manner, realizing the synchronous and efficient clamping of batches of bar wires.

[0027] A top plate 27 is fixedly connected to the upper end of several guide rods 2. The top plate 27 serves as the support platform for the upper components and must have sufficient strength and stability. A hydraulic cylinder 28 is fixedly installed on the upper end of the top plate 27. One end of the piston rod of the hydraulic cylinder 28 passes through the top plate 27 and is fixedly connected to the upper end of one of the movable clamping platforms 23. The hydraulic cylinder 28 serves as the key power source for driving the movable clamping platform 23 to rise and fall. It can smoothly drive the movable clamping platform 23 to move up and down along the guide rods 2, thereby realizing the clamping and releasing action of the bar wire.

[0028] The upper end of the fixed base 1 is provided with a guide slope 3, which enables the bar wire to be quickly discharged and collected after cutting. The upper end of the fixed base 1 is provided with a moving groove 4. A servo motor 5 is fixedly installed on the front of the fixed base 1. The servo motor 5 serves as the power core for the movement of the adjusting baffle 10. It has high-precision speed control and position feedback capabilities and can accurately drive the adjusting baffle 10 to adjust its position according to processing requirements.

[0029] The output shaft of the servo motor 5 is fixedly mounted with a lead screw 6 via a coupling. One end of the lead screw 6 passes through and extends into the interior of the moving groove 4. The servo motor 5 drives the lead screw 6 to rotate stably in both the forward and reverse directions.

[0030] One end of the lead screw 6 is rotatably connected to the inner rear wall of the moving groove 4 via a bearing. This connection method can ensure the flexible rotation of the lead screw 6 and provide stable support to prevent axial and radial movement.

[0031] The lead screw 6 has an external threaded connection to a threaded block 7. The external part of the threaded block 7 is slidably connected to the inner wall of the moving groove 4. The threaded fit between the threaded block 7 and the lead screw 6 is finely ground, with a very small transmission clearance, ensuring that the threaded block 7 can slide precisely along the inner wall of the moving groove 4 as the lead screw 6 rotates. The sliding connection design between the external part of the threaded block 7 and the inner wall of the moving groove 4 further ensures the smoothness and directionality of its movement.

[0032] A pointer 8 is fixedly connected to the upper end of the threaded block 7. The pointer 8 is usually made of a lightweight, rigid and easy-to-observe material, such as aluminum alloy or engineering plastic. It moves synchronously with the threaded block 7. Together with the pre-marked and accurate scale groove on the fixed base 1, it allows the operator to quickly and intuitively determine the moving distance of the adjustment baffle 10 from a distance, which greatly improves the convenience and accuracy of operation.

[0033] The upper end of the threaded block 7 is fixedly connected to a column 9. The column 9 serves as a vertical support component connecting the adjusting baffle 10 and the threaded block 7. It must have sufficient strength and verticality to ensure that the adjusting baffle 10 will not tilt or shake during movement.

[0034] An adjusting baffle 10 is fixedly connected to one side of the column 9. The adjusting baffle 10 is driven by the lead screw 6 and the threaded block 7 through the servo motor 5 to move, thereby quickly and accurately adjusting the position according to different cutting requirements, realizing efficient limiting of the cutting length of bar and wire, and further improving the efficiency and quality of the entire bar and wire processing.

[0035] The working process of this utility model:

[0036] Step 1: Start the servo motor 5 to drive the lead screw 6 to rotate. The rotation of the lead screw 6 causes the threaded block 7 to move through the moving slot 4. The movement of the threaded block 7 drives the position adjustment baffle 10 to move and adjust through the column 9, thereby limiting the position according to the length of the cutting rod wire. The movement of the threaded block 7 also drives the pointer 8 to move. The movement of the pointer 8, in conjunction with the scale groove on the fixed base 1, allows the operator to quickly determine the moving distance of the adjustment baffle 10.

[0037] Step two: Place the bar wires sequentially into the first V-shaped clamping groove above the fixed clamping table 21, and make one end of it contact the adjusting baffle 10. Then, start the piston rod of the hydraulic cylinder 28 to extend. The piston rod of the hydraulic cylinder 28 drives several moving clamping tables 23 to move down synchronously through the cooperation of the fixed block 25 and the synchronizing block 26. The guide rod 2 guides the movement of the moving clamping tables 23, thereby fixing multiple bar wires synchronously. The cooperation of the first anti-slip pad 22 and the second anti-slip pad 24 ensures stable clamping of a single bar wire, improving the stability during subsequent cutting.

[0038] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
