Description

Technical Field

[0001] The utility model relates to the technical field of copper rod production, in particular to a copper rod extrusion mechanism. Background Art

[0002] After searching the patent with the announcement number CN 218224096 U, the first two-way screw drives the first slider to move, the first slider drives the placement frame to move, and the placement frame drives the traction roller and the limit rod to move, so that the traction roller contacts the copper rod and supports and clamps the copper rod;

[0003] During this process, the copper rod near the extrusion position of the extrusion die has a relatively high temperature and is more prone to deformation. Therefore, relatively dense support is required at this position to reduce the bending deformation of the copper rod. The copper rod far away from the extrusion die has been completely cooled, so no excessive support is required. If there are too many support points at this position, it will easily increase the weight of the entire device. Utility Model Content

[0032] The utility model is further described below in conjunction with the accompanying drawings:

[0033] like Figure 1-Figure 9 As shown, a copper rod extrusion mechanism includes an extrusion mechanism 1 for pushing and extruding the copper rod raw material, a fixing frame 4 is arranged at the lower side of the extrusion mechanism 1, and a support mechanism 2 for preventing the copper rod from bending after extrusion, the support mechanism 2 is located at the inner side of the clamping mechanism 3, and a driving component for driving the support mechanism 2 to move is arranged at one side of the clamping mechanism 3;

[0034] In this embodiment: the extrusion mechanism 1 includes an extrusion bracket 12, an extrusion motor 11 is fixed at the front end of the extrusion bracket 12, an extrusion die 14 is fixed inside the extrusion bracket 12, and two push wheels 13 that are symmetrical up and down are arranged on one side of the extrusion die 14. The two push wheels 13 are both rotatably connected to the extrusion bracket 12, and the push wheels 13 at the rear end thereof are driven to rotate by the rotating part of the extrusion motor 11, and then the two push wheels 13 start to rotate in opposite directions, thereby driving the copper rod raw material to be pushed into the extrusion die 14, and then the copper rod raw material passing through the extrusion die 14 is continuously pushed and extruded to form the required copper rod;

[0035] In this embodiment: the support mechanism 2 includes a toggle plate 22, and two mutually symmetrical support frames 21 are slidably connected to the upper end of the toggle plate 22. Support wheels 23 are provided on the upper ends of the two support frames 21, and a return spring 24 is provided between the two support frames 21. Elastic sheets 25 are fixed on one side of the two support frames 21. The support frames 21 on the toggle plate 22 are clamped and supported by the two support wheels 23 under the action of the clamping mechanism 3.

[0036] In this embodiment, the clamping mechanism 3 includes a clamping base 31, the upper end of the clamping base 31 is rotatably connected to two mutually symmetrical gathering frames 32, the gathering frames 32 are far away from the rubber strip 33 at the swing center, the lower end of the rubber strip 33 is fixed to the end of the clamping base 31, the clamping base 31 is provided with a slide groove near the gathering frame 32, and a clamping plate frame 34 is slidably connected in the slide groove, the clamping plate frame 34 is fixed to the slide by a limit pin 35, and the upper end of the clamping base 31 is located at the swing center of the gathering frame 32. A pin is fixed at the center position for supporting the gathering frame 32 to allow it to rotate. The side where the two gathering frames 32 are close to each other is an arc-shaped structure, and it is fixed to the rubber strip 33 by screws. The clamping machine base 31 is located at the gathering frame 32 and has a concave groove, and the gathering frame 32 is located in the concave groove. The top of the clamping plate frame 34 and the top of the clamping machine base 31 are each provided with three groups of corresponding limiting holes. The limiting pins 35 are inserted into the limiting holes of the clamping machine base 31 and the clamping plate frame 34. The front of the toggle plate 22 The rear two ends are cylindrical structures, and a sliding groove that cooperates with the cylindrical structure of the toggle plate 22 is opened on the inner wall of the clamping machine base 31. When the extruded copper rod enters between the two support wheels 23, the support frames 21 between the two clamping plate frames 34 approach each other, and then the support wheels 23 on the support frames 21 clamp the copper rod. At this time, at the position of the copper rod that has just been extruded, multiple groups of support frames 21 will gather under the action of the gathering frame 32, and then densely support the copper rod that has just been extruded. At this position, the elastic sheet 25 is in a compressed state; when the support frame 21 slides over the gathering frame 32, since the toggle plate 22 is separated from the obstruction of the gathering frame 32, the elastic sheet 25 stretches and makes the gathered toggle plates 22 move away from each other, and then no longer densely support; when the two support frames 21 are separated from the clamping plate frame 34, the two support frames 21 that are close to each other are moved away from each other along the toggle plate 22 by the action of the reset spring 24, and then the support wheel 23 is separated from the support of the copper rod.

[0037] In this embodiment: the driving component includes a driving motor 5, which is arranged at a position of the clamping base 31 close to the extrusion bracket 12, and the fixing part of the driving motor 5 is fixedly connected to the front end of the clamping base 31, and the clamping base 31 is rotatably connected to a dial wheel 6 at a position close to the extrusion bracket 12. The outer side of the dial wheel 6 is provided with teeth for cooperating with the toggle plate 22. The rotating part of the driving motor 5 is used to drive the dial wheel 6 at its rear end to rotate inside the clamping base 31, and then the toggle plate 22 on the opposite side is transported upward along one side of the clamping base 31, and the toggle plate 22 on the other side of the clamping base 31 will slide toward the dial wheel 6 along the inclination of the sliding groove.

[0038] Working principle: When in use, the pushing wheel 13 at the rear end is driven to rotate by the rotating part of the extrusion motor 11, and then the two pushing wheels 13 start to rotate in opposite directions, thereby driving the copper rod raw material to be pushed into the extrusion die 14, and then the copper rod raw material passing through the extrusion die 14 is continuously pushed and extruded to form the required copper rod;

[0039] At this time, the copper rod will extend into the position above the clamping machine base 31, and then the driving motor 5 will drive the dial wheel 6 to rotate, and then the support mechanism 2 will be transported upward along one side of the clamping machine base 31. At this time, the support mechanism 2 sent to the upper position of the clamping machine base 31 will allow the two support frames 21 on the same dial plate 22 to approach each other under the action of the two clamping plate frames 34, and then the support wheels 23 on the support frames 21 will clamp the copper rod. At this time, at the position of the copper rod that has just been squeezed out, multiple groups of support frames 21 will gather under the action of the gathering frame 32. When the support frame 21 slides over the gathering frame 32, the toggle plate 22 is separated from the obstruction of the gathering frame 32, and then the elastic sheet 25 stretches and the gathered toggle plates 22 move away from each other, and then no longer supports densely; when the two support frames 21 are separated from the clamping plate frame 34, the two support frames 21 close to each other are separated from each other along the toggle plate 22 by the action of the reset spring 24, and then the support wheel 23 is separated from the support of the copper rod;

[0040] In addition, the distance that the clamping plate frame 34 extends into the clamping base 31 can be adjusted by pulling out the limit pin 35, thereby changing the support distance between the two support wheels 23, and the blocking force of the entire gathering frame 32 can be changed by adjusting the fixed length of the rubber strip 33 on the clamping base 31, thereby adjusting the dense support distance of the support mechanism 2.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
