Description

Technical Field

[0001] The utility model relates to the technical field, and specifically relates to a wire drawing machine correction device for screw processing. Background Technique

[0002] During the screw processing, a wire drawing machine is required to draw metal bars. During the drawing process, the wire may be deformed due to factors such as residual stress, material properties, or mechanical action. The correction device can effectively eliminate these deformations and restore the wire to an ideal shape and size. Most of the existing correction devices adopt two-way correction. The two-way correction method can better ensure the straightness and roundness of the wire than the traditional single-direction correction, making the wire more in line with the quality requirements after drawing.

[0003] Patent No. CN 218191770 U discloses a wire drawing machine correction device for screw processing, including a horizontal rolling wheel, a vertical rolling wheel, a four-link structure, a swing rod, etc. The upper and lower sides of the wire are corrected by the vertical rolling mechanism; by setting a horizontal rolling mechanism, the left and right sides of the wire are corrected: by performing two-way correction on the wire, the straightening effect of the wire is improved; the correction efficiency of the wire is greatly improved by the left and right movement of the horizontal rolling wheel and the vertical rolling wheel.

[0004] However, in use, it has the following defects:

[0005] Although the vertical rolling wheel and the horizontal rolling wheel are respectively moved relatively and left and right to perform two-way correction, since the distance between the vertical rolling wheel and the horizontal rolling wheel is fixedly set, only single wire correction can be satisfied during correction, and wires with different thicknesses cannot be constrained, thus affecting the practicability of the device. Content of the Utility Model

[0006] The purpose of the utility model is to provide an electronic auxiliary evaluation device for paperless bidding, which solves the problem that although the vertical rolling wheel and the horizontal rolling wheel are respectively moved relatively and left and right to perform two-way correction, since the distance between the vertical rolling wheel and the horizontal rolling wheel is fixedly set, only single wire correction can be satisfied during correction, and wires with different thicknesses cannot be constrained, thus affecting the practicability of the device as mentioned in the background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A wire drawing machine correction device for screw processing, comprising a base, a mounting frame, a horizontal rolling wheel and a plug rod. The center of the top end of the base is fixedly installed with an adjustment groove. The inside of the adjustment groove is rotatably connected with a first bidirectional lead screw. Both sides of the surface of the first bidirectional lead screw are threadedly connected with a first threaded block. The top end of the first threaded block is fixedly connected with a mounting frame. The top end of the mounting frame is penetrated and provided with a top groove. The inside of the top groove is slidably connected with a T-shaped block. And a bottom groove is opened on the surface of the mounting frame directly below the top groove. The inside of the bottom groove is rotatably connected with a second bidirectional lead screw. Both sides of the surface of the second bidirectional lead screw are threadedly connected with a second threaded block. The bottom of the T-shaped block and the top end of the second threaded block are both fixedly connected with a plug rod. The T-shaped block and the second threaded block are respectively movably inserted into both ends of the longitudinal rolling wheel through the plug rod. And the two ends of the horizontal rolling wheel are also movably inserted with T-shaped blocks of the same size.

[0008] In this technical solution, the wire is threaded through between the two driving rollers, and then passes through between the longitudinal rolling wheel and the horizontal rolling wheel in sequence, and finally passes out between the driving rollers on the other side. After the driving motor is started, it will drive the first bidirectional lead screw to rotate, so that the first threaded block drives the mounting frame to move relatively. At this time, the horizontal rolling wheel and the longitudinal rolling wheel in contact with the wire will simultaneously correct the surface of the wire horizontally and longitudinally. Through the bottom groove, the top groove and the vertical groove, the distance between the longitudinal rolling wheel and the horizontal rolling wheel can be adjusted. Manually rotate the convex block to drive the second bidirectional lead screw, so that the two second threaded blocks move relatively. The second threaded block will drive the longitudinal rolling wheel to change the distance. Similarly, slide the T-shaped block inside the vertical groove to change its up and down position and fix it with a fixing bolt, thereby changing the distance between the horizontal rolling wheels, adapting to the correction requirements of different wires, improving the practicability of the device. At the same time, through the T-shaped block, the second threaded block and the plug rod, it is convenient to disassemble and assemble the longitudinal rolling wheel and the horizontal rolling wheel. The two ends of the horizontal rolling wheel and the longitudinal rolling wheel are connected to the T-shaped block and the second threaded block through the plug rod. When disassembly is required, slide the T-shaped block out of the top groove or the vertical groove, and the horizontal rolling wheel and the longitudinal rolling wheel can be disassembled, so as to replace and maintain them to ensure the subsequent correction effect. The structure is simple and the disassembly and assembly are convenient.

[0009] As an optional solution of the technical solution of the present utility model, center frames are fixedly installed on the surface of the base on both sides of the center of the adjustment groove. The top end of the center frame is provided with a vertical groove. The inside of the vertical groove is slidably connected with a T-shaped block.

[0010] As an optional solution of the technical solution of the present utility model, the right end of the first bidirectional lead screw is fixedly connected to the output end of the driving motor. The driving motor is fixedly installed on the outer wall of the right end of the adjustment groove.

[0011] As an alternative embodiment of the technical solution of the present utility model, a fixing bolt is threadedly connected to the surface of the I-shaped block on the side opposite to the insertion rod.

[0012] As an alternative embodiment of the technical solution of the present utility model, the outer end of the second bidirectional lead screw penetrates through the bottom groove and is fixedly connected to the convex block.

[0013] As an alternative embodiment of the technical solution of the present utility model, two support frames are fixedly installed on the top surface of the base on both the left and right sides of the adjustment groove, and two transmission rollers are rotatably connected between the two support frames.

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

[0015] 1. Through the bottom groove, the top groove and the vertical groove, the present utility model can adjust the distance between the longitudinal rolling wheel and the transverse rolling wheel. Manually rotate the convex block to drive the second bidirectional lead screw, so that the two second threaded blocks move relative to each other. The second threaded block will drive the longitudinal rolling wheel to change the distance. Similarly, slide the I-shaped block inside the vertical groove to change its vertical position and fix it with a fixing bolt, thereby changing the distance between the transverse rolling wheels, adapting to the correction requirements of different wire materials, and improving the practicability of the device.

[0016] 2. Through the I-shaped block, the second threaded block and the insertion rod, the present utility model can facilitate the disassembly and assembly of the longitudinal rolling wheel and the transverse rolling wheel. Both ends of the transverse rolling wheel and the longitudinal rolling wheel are connected to the I-shaped block and the second threaded block through the insertion rod. When disassembly is required, slide the I-shaped block out of the top groove or the vertical groove, and the transverse rolling wheel and the longitudinal rolling wheel can be disassembled, so as to replace and maintain them to ensure the subsequent correction effect. The structure is simple and the disassembly and assembly are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the following will be further elaborated in combination with specific implementation modes.

[0024] As Figure 1 shown, a wire drawing machine correction device for screw processing includes a base 1, an installation frame 7, a transverse rolling wheel 121 and an insert rod 132. A central part of the top end of the base 1 is fixedly installed with an adjusting groove 4. The inside of the adjusting groove 4 is rotatably connected with a first double-headed screw rod 5. The right end of the first double-headed screw rod 5 is fixedly connected to the output end of the driving motor 501. The driving motor 501 is fixedly installed on the outer wall of the right end of the adjusting groove 4.

[0025] As Figure 1 shown, central parts of both sides of the surface of the base 1 of the adjusting groove 4 are fixedly installed with central frames 14. The top ends of the central frames 14 are provided with vertical grooves 15. The inside of the vertical grooves 15 is slidably connected with I-shaped blocks 13. The I-shaped blocks 13 move up and down in the vertical grooves 15, thereby changing the distance between the transverse rolling wheels 121.

[0026] As Figure 1 shown, two support frames 2 are fixedly installed on the top surfaces of both sides of the base 1 of the adjusting groove 4, and two driving rollers 3 are rotatably connected between the two support frames 2. The upper driving roller 3 is in a movable state and contacts the lower driving roller 3 under the action of gravity. When the wire passes through, the upper driving roller 3 will be lifted up, pressing the wire between the two driving rollers 3.

[0027] As Figure 2As shown in the figure, on both sides of the surface of the first double-headed lead screw 5 are threadedly connected with first threaded blocks 6. The top ends of the first threaded blocks 6 are fixedly connected with mounting frames 7. The top ends of the mounting frames 7 are penetrated and provided with top grooves 9. Inside the top grooves 9 are slidably connected with I-shaped blocks 13. On the surface of the I-shaped block 13 on the opposite side of the insertion rod 132 is threadedly connected with a fixing bolt 131. And on the surface of the mounting frame 7 directly below the top groove 9 is provided with a bottom groove 8. Inside the bottom groove 8 is rotatably connected with a second double-headed lead screw 10. The outer ends of the second double-headed lead screw 10 penetrate the bottom groove 8 and are fixedly connected with bumps 101. On both sides of the surface of the second double-headed lead screw 10 are threadedly connected with second threaded blocks 11. The second threaded blocks 11 drive the upper longitudinal rolling wheels 12 to move relatively to change the spacing. After the fixing bolt 131 is tightened, the upper I-shaped block 13 will be tightly squeezed on the surface of the top groove 9, so as to maintain stability and facilitate the rotation of the longitudinal rolling wheel 12.

[0028] As Figure 3 and Figure 4 shown in the figure, at the bottom of the I-shaped block 13 and the top ends of the second threaded blocks 11 are fixedly connected with insertion rods 132. The I-shaped block 13 and the second threaded blocks 11 are respectively movably inserted at both ends of the longitudinal rolling wheel 12 through the insertion rods 132. And at both ends of the transverse rolling wheel 121 are also movably inserted with I-shaped blocks 13 of the same size. The I-shaped block 13 is a universal part and can slide freely in the top groove 9 and the vertical groove 15.

[0029] During actual use, the wire is threaded through between the two driving rollers 3, then passes through between the longitudinal rolling wheel 12 and the transverse rolling wheel 121 in sequence, and finally passes out between the driving rollers 3 on the other side. After the driving motor 501 is started, it will drive the first double-headed lead screw 5 to rotate, so that the first threaded block 6 drives the mounting frame 7 to move relatively. At this time, the transverse rolling wheel 121 and the longitudinal rolling wheel 12 in contact with the wire will simultaneously correct the surface of the wire horizontally and longitudinally. Manually rotate the bump 101 to drive the second double-headed lead screw 10, so that the two second threaded blocks 11 move relatively. The second threaded blocks 11 will drive the longitudinal rolling wheel 12 to change the spacing. Similarly, slide the I-shaped block 13 inside the vertical groove 15 to change its vertical position and fix it with the fixing bolt 131, so as to change the spacing of the transverse rolling wheel 121 and adapt to the correction requirements of different wires, improving the practicability of the device. The two ends of the transverse rolling wheel 121 and the longitudinal rolling wheel 12 are connected to the I-shaped block 13 and the second threaded block 11 through the insertion rod 132. When disassembly is required, slide the I-shaped block 13 out of the top groove 9 or the vertical groove 15, and the transverse rolling wheel 121 and the longitudinal rolling wheel 12 can be disassembled, so as to replace and maintain them to ensure the subsequent correction effect. The structure is simple and the disassembly and assembly are convenient.
