Description

TECHNICAL FIELD

[0001] The utility model relates to a wire drawing die clamp for wire drawing polishing hole belongs to wire drawing die clamp technical field. BACKGROUND

[0002] Wire drawing die is used for drawing or extruding metal wire product meeting the specification and shape, and the smoothness of wire drawing hole directly influences the qualified rate of metal wire product. The diameter of wire drawing hole of general wire drawing die is very small, only 4-6mm, and the length of hole is about 15-20mm, and the processing technology is mostly that a wire drawing hole original hole slightly smaller than the specified specification is first pressed on the wire drawing die, and then the round hole is polished and processed. Since the diameter of wire drawing hole is too small, the core rod is easily broken and blocked by using core rod insertion forming, and currently micro-beam laser polishing is generally adopted, but the operation precision requirement is too high, and slight deviation will cause the inner wall surface of wire drawing hole to change and exceed the specified inner hole diameter, thereby leading to the whole wire drawing die to be scrapped.

[0003] To solve the above problems, the company has invented a polishing and polishing method for wire drawing hole of wire drawing die, and a key problem involved in the method is that a flow channel which cannot be fixed and sealed must form a particle liquid columnar jet under pressure, and particle liquid leakage is not allowed. The flow channel which cannot be fixed and sealed is a flow channel temporarily constructed in a pasting and pressing connection mode by a jet flow channel, a return flow channel and a wire drawing hole of a wire drawing die, the wire drawing hole of the wire drawing die is located between the jet flow channel and the return flow channel, and the wire drawing die needs to rotate at high speed with the axis of the wire drawing hole as the axis, therefore, fixed sealing cannot be implemented between the wire drawing hole of the wire drawing die and the jet flow channel, and between the wire drawing hole of the wire drawing die and the return flow channel. Here, a pressure liquid flow device developed by the company is involved, which has two jet flow nozzles of jet flow, and the two jet flow nozzles need to be pasted and pressed on both ends of the wire drawing die in a pasting and pressing mode when applied, so that the jet flow holes of the two jet flow nozzles can temporarily form a section of coaxial pressure flow channel which cannot be fixed and sealed with the wire drawing hole. Here, the problems of how to make the wire drawing die rotate and how to make the two jet flow nozzles pasted and pressed on both ends of the wire drawing die are involved, which actually involve how to assemble the above-mentioned related parts and the clamp for clamping the wire drawing die.

DETAILED DESCRIPTION

[0020] In order to facilitate the description and understanding of the utility model, the two jet nozzles and the wire drawing die of the pressure liquid flow device involved in the utility model are simply described below.

[0021] As Figure 4 shown, the two jet nozzles of the pressure liquid flow device include jet nozzle one 6 and jet nozzle two 7 respectively having jet hole one 61 and jet hole two 71, the jet nozzle one 6 and the jet nozzle two 7 are conical nozzles respectively having outer taper surface one 62 and outer taper surface two 72, the rear ends of the jet nozzle one 6 and the jet nozzle two 7 are respectively connected with a rigid connecting pipe one 8 and a connecting pipe two 9, the outer peripheries of the middle parts of the connecting pipe one 8 and the connecting pipe two 9 respectively have stop flange one 81 and stop flange two 91 which are threadedly matched, rotating the stop flange one 81 and the stop flange two 91 can make the stop flange one 81 and the stop flange two 91 respectively axially move on the connecting pipe one 8 and the connecting pipe two 9.

[0022] As Figure 4 shown, the wire drawing hole 101 of the wire drawing die 10 is changed into a taper hole shape respectively having inner taper surface one 111 and inner taper surface two 112 at both ends, the tapers of the inner taper surface one 111 and the inner taper surface two 112 are respectively consistent with the tapers of the outer taper surface one 62 and the outer taper surface two 72.

[0023] The utility model is further described below in combination with the embodiments and the drawings:

[0024] As Figure 1 , 5As shown in Figure 6, a wire drawing die fixture for grinding wire drawing holes using liquid flow includes a base 100, a support 1, a support 2, a pressing component 3, a pressing component 4, a rotor 5, and a motor 56. The support 1 and the support 2 are symmetrically installed in the middle area of ​​the base 100. The rotor 5 is installed between the support 1 and the support 2. The motor 56 is installed on the base 100, and there is a transmission structure between the motor 56 and the rotor 5. The pressing component 3 and the pressing component 4 are installed at both ends of the base 100 and are used to press the jet nozzle 6 and the jet nozzle 7 of the pressure liquid flow device onto the two ends of the wire drawing die 10 on the rotor 5, respectively. In application, the pressure components 3 and 4 respectively press the jet nozzles 6 and 7 of the pressure fluid flow device onto the two ends of the drawing die 10 on the rotor 5. This means that the outer conical surface 62 of jet nozzle 6 and the outer conical surface 72 of jet nozzle 7 are pressed against the inner conical surfaces 111 and 112 at both ends of the drawing hole 101, respectively, thus temporarily forming a straight flow channel between the jet hole 61, the drawing hole 101, and the jet hole 71. Jet nozzles 6 and 7 alternately spray columnar jets into the drawing hole 101, axially scouring and polishing it. When one jet nozzle forms a columnar jet under positive pressure, the other forms a negative pressure that draws in the columnar jet. At the same time, the motor drives the wire drawing die 10 to rotate, causing the inner wall of the wire drawing hole 101 to form circumferential friction with the columnar jet, thus performing circumferential brushing and polishing on the wire drawing hole 101. In this way, the wire drawing die is clamped and the jet nozzles 6 and 7 are pressed against both ends of the wire drawing die 10.

[0025] like Figure 1 As shown in Figure 3, the rotor 5 is provided with a clamping groove 53 with a semi-annular cross-section for clamping the wire drawing die 10. At both ends of the rotor 5 are tubular shafts 51 and 52, respectively mounted on supports 1 and 2. Tubular shafts 51 and 52 have through holes 511 and 521 communicating with the clamping groove 53, respectively. The through holes 511 and 521 share the same axis as the wire drawing hole 101 of the clamped wire drawing die 10, and the rotor 5 rotates around the axis of the wire drawing hole 101. Threaded pin holes are provided at both ends of the rotor 5 above the opening of the clamping groove 53, into which bolts 54 can be inserted to press down on both ends of the wire drawing die 10. In this way, clamping and fixing the wire drawing die 10 is very convenient and secure, and through holes 511 and 521 are provided as channels for the jet nozzle 6 and jet nozzle 7 to press against the wire drawing die.

[0026] A gear 55 is provided on support 1 or support 2 to drive the rotor 5 to rotate, and a transmission structure is provided between the gear 55 and the motor 56.

[0027] like Figure 1As shown in Figure 6, the first pressing component 3 includes a pressing seat 31 with a guide hole 311 and a compression spring 32, and the second pressing component 4 includes a pressing seat 41 with a guide hole 411 and a compression spring 42. Both the first and second guide holes 311 and 411 are coaxial with the first and second through holes 511 and 521, respectively. The connecting pipe 8 is located in the through hole 511 and the guide hole 311. The stop flange 81 is located between the tubular shaft 51 and the pressing seat 31. The compression spring 32 is fitted around the outer periphery of the connecting pipe 8 between the stop flange 81 and the pressing seat 31, so that the outer conical surface 62 of the jet nozzle 6 is aligned with the wire drawing hole 10. 1. The inner conical surface 111 of the tapered hole at one end is pressed against each other; the connecting tube 2 9 is located in the through hole 2 521 and the guide hole 2 411, the stop flange 2 91 is located between the tubular shaft 2 52 and the pressure seat 2 41, and the compression spring 2 42 is fitted on the outer periphery of the connecting tube 2 9 between the stop flange 2 91 and the pressure seat 2 41, so that the outer conical surface 2 72 of the jet nozzle 2 7 is pressed against the inner conical surface 112 of the tapered hole at one end of the wire drawing hole 101. In this way, the outer conical surfaces 62 and 72 of the jet nozzle 1 6 and the jet nozzle 2 7 can always maintain a tight press against the inner conical surfaces 111 and 112 of the tapered holes at both ends of the wire drawing hole 101, and the tightness of the press can be maintained at a suitable state by adjusting the stop flange 81 and the stop flange 91.

[0028] Obviously, the above embodiments are only used to illustrate the present invention and cannot be used to limit the scope of protection covered by the present invention. Any improvements or modifications made by any person without departing from the principle of the present invention should be considered to fall within the scope of protection of the present invention.
