Description

Technical Field

[0001] The invention belongs to the technical field of aluminum profile extrusion dies, in particular to a heating type industrial aluminum profile extrusion die. Background Art

[0002] The heated industrial aluminum profile extrusion die uses a heating wire embedded in the die. By heating the die and the aluminum profile, the temperatures of the two are equalized or crystallized, thereby changing the fluidity of the aluminum profile when the aluminum rod passes through the die, improving extrusion efficiency and product quality, and meeting the industry's demand for high-precision and high-performance aluminum profiles.

[0003] Usually, an aluminum profile extrusion die includes an upper die (front die) and a lower die (rear die). Before extruding the aluminum rod, the operator needs to feed the heated aluminum rod into a rack (the rack is a block with a tubular through hole in the middle, and the aluminum rod is placed in the tubular through hole). The rack moves toward the die and fits tightly with the front die of the die. Then, the extruder runs to push the aluminum rod in the rack into the die for extrusion. After an aluminum rod is extruded, the rack is separated from the die. At this time, the shearing knives on both sides of the die will shear the remaining material at both ends of the die to facilitate subsequent loading of the device. Generally speaking, there will be a section at the connection between the front die and the rear die. At this time, for the aluminum rod material at the same height as the section, when this part needs to pass through the diverter hole or through the belt, the aluminum rod material at the end face has a longer flow distance and a more complex flow environment than the aluminum rod material part at the same height as the separation diverter hole or through the belt (that is, the aluminum rod at the section is temporarily retained at the section and is continuously sheared). Under normal circumstances, the mold and the aluminum rod will be heated to 480°C for extrusion operation, but even in this case, the aluminum rod raw material will continue to remain at the section and circulate, and fatigue will still occur, resulting in cracks on the surface of the extruded aluminum profile, local fractures, or a decrease in overall plasticity.

[0004] Therefore, in order to solve the above problems, a heating type industrial aluminum profile extrusion die is proposed. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a heated industrial aluminum profile extrusion die, which solves the problem that when the aluminum rod passes through the extrusion die, the aluminum rod raw material continues to remain at the cross section, resulting in reduced quality of the extruded aluminum profile.

[0014] The top end of the push rod abuts against the diverter block, and when the push rod moves upward, it can squeeze the diverter block to move outward.

[0015] Preferably, a notch is provided at one end of the connecting rod located inside the front mold, and when the front mold is separated from the rear mold in an initial state, the bottom end of the push rod can be detached from the notch of the connecting rod.

[0016] Preferably, one end of the tension spring combination slider extends to the outside of the rear mold and is provided with a groove with an opening facing upward.

[0017] Preferably, an aluminum rod retraction assembly is elastically connected inside the annular block; the aluminum rod retraction assembly includes an elastic block 1 elastically connected to the annular block, one end of the elastic block 1 extends into the interior of the front mold and is movably connected to the front mold, an extrusion surface and an inclined block are respectively provided at both ends of the elastic block 1, a guide groove is also provided inside the annular block, a convex shaft that can slide in the guide groove is fixedly connected to the elastic block 1, and an elastic block 2 is elastically hinged inside the front mold, and the inclined block has an overlapping portion with the elastic block 2 in the horizontal direction.

[0018] Preferably, a socket 1 is provided on the front mold, an isolation rod is fixed inside the socket 1, one end of the isolation rod extends to the inner wall of the annular block and is movably connected to the inner wall of the annular block, and one end of the isolation rod extends to one end of the elastic block and separates the annular block cavity from the elastic block 1.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the above scheme, after the aluminum rod enters the annular block from the material rack, the end of the aluminum rod will be diverted by the diverter bridge 2 and then diverted axially by the diverter bridge 1. At the same time, the diverter surface will guide the metal flow overlapping with the diverter block in the axial direction to the corner of the rectangular frame, and balance the metal flow through the gaps between adjacent diverter bridges 1 and diverter bridges 2. Subsequently, the diverted aluminum rod will also be guided by the guide curved surface and the diverted metal will be welded through the diverter hole and the welding chamber, and finally extruded through the gap between the working belt and the core body to form an aluminum profile, thereby avoiding the situation where the aluminum rod raw material continues to remain at the cross section when the aluminum rod passes through the extrusion die, resulting in a decrease in the quality of the extruded aluminum profile.

[0021] When the above scheme cuts the residual material at the end of the rear mold through the shearing device, after the cutting knife completes cutting the residual material, the bottom of the cutting knife will abut against the tension spring combination slider and push the tension spring combination slider downward to make the connecting rod rotate around the axis, thereby driving the push rod upward to squeeze the diverter block. At this time, the diverter block will push the end of the residual material in the front mold out of one end of the front mold, so as to facilitate the shearing knife to cut the residual material of the aluminum bar at the front mold;

[0022] The above scheme is that when the diverter block pushes out the residual material, the inclined block will squeeze and pass over the elastic block 2. The feeding rack for the next group of aluminum bars will first squeeze the annular block to reset, so that the inclined block squeezes the elastic block 2. Since the inclined angle of the inclined block and the elastic block 2 relative to each other is large, and the elastic block 2 cannot rotate clockwise at this time, the elastic block 2 will force the inclined block to drive the elastic block downward and make the extrusion surface squeeze the end of the residual aluminum bar material, and move the residual aluminum bar material as a whole toward the rear die outlet. When the inclined block passes over the elastic block 2, the elastic block 1 will be reset by the elastic force, and the annular block will also be reset at the same time. At this time, after the rear die end is cut, a gap will be left between the end of the metal residual material and the end of the annular block, which is convenient for the entry of the next group of bars.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 11 As shown, the present invention provides a heated industrial aluminum profile extrusion die, comprising a front die 1 and a rear die 2 mounted thereon, and further comprising: a core assembly 3, which is arranged inside the front die 1 and extends into the rear die 2; an annular block 6, which is movably sleeved at one end inside the front die 1; an aluminum rod pushing assembly 5, which is respectively arranged in the front die 1 and the rear die 2 and is used for the shearing device to shear the residual material at the end of the rear die 2 and then push the annular block 6 outward; a guide curved surface 11 and a diverter hole 13 are provided on the front die 1; a working belt 21 is provided on the rear die 2;

[0037] The core assembly 3 includes a core body 31 disposed inside the front mold 1, a shunt bridge 1 32 is fixedly connected to the outer periphery of the core body 31 in an annular array, the core body 31 is fixedly connected to the front mold 1 through the shunt bridge 1 32, one end of the core body 31 is elastically connected to a shunt block 33, the core body 31 and the shunt block 33 have a tendency to move toward each other, a shunt bridge 2 34 with a thickness less than the shunt bridge 1 32 is fixedly connected to the outer periphery of the shunt block 33 in an annular array, and the other end of the shunt bridge 2 34 is fixedly connected to the inner wall of the annular block 6;

[0038] One end of the mold core body 31 passes through the working belt 21 and forms an annular rectangular frame with the inner wall of the working belt 21; a circumferential array of diversion surfaces 331 for diverting the aluminum rod toward the rectangular frame is provided on the diversion block 33; a second plug hole 22 is provided on the rear mold 2, and a pin 12 that can be inserted into the second plug hole 22 is fixedly connected to the front mold 1;

[0039] A welding part 4 is also provided between the front mold 1 and the rear mold 2; the welding part 4 is provided with a welding chamber 41 sleeved on the outside of the mold core body 31, the diverter hole 13 is connected to the working belt 21 through the welding chamber 41, both ends of the welding chamber 41 are rectangular channels, and the rectangular channel gradually shrinks from one side of the front mold 1 to the rear mold 2 to a rectangular hole with the same cross-section as the working belt 21; the rear mold 2 is provided with a plug hole 23, and the welding part 4 is fixed with a plug pin 2 42 that can be inserted into the plug hole 23

[0040] By adopting the above scheme, after the aluminum rod enters the annular block 6 from the material rack, the end of the aluminum rod will be diverted by the diverter bridge 2 34 and then diverted axially by the diverter bridge 1 32. At the same time, the diverter surface 331 will guide the metal flow overlapping with the diverter block 33 in the axial direction to the corner of the rectangular frame, and balance the metal flow through the gaps between adjacent diverter bridges 1 32 and diverter bridges 2 34. Subsequently, the diverted aluminum rod will also be guided by the guide surface 11 and pass through the diverter hole 13 through the welding chamber 41 to complete the welding of the diverted metal, and finally be extruded through the gap between the working belt 21 and the core body 31 to form an aluminum profile, thereby avoiding the situation where the aluminum rod raw material continues to remain at the cross section when the aluminum rod passes through the extrusion die, resulting in a decrease in the quality of the extruded aluminum profile.

[0041] like Figure 1 , Figure 2 and Figure 4-Figure 8 As shown, the aluminum rod ejection assembly 5 includes a tension spring combination slider 51 elastically connected to the bottom of the rear mold 2, a connecting rod 52 is also hinged in the rear mold 2, a push rod 53 is movably connected in the shunt bridge 1 32, the top and bottom ends of the push rod 53 extend to the mold core body 31 and the front mold 1 respectively, one end of the connecting rod 52 extends to the inside of the front mold 1 and is movably connected to the bottom end of the push rod 53, and the other end of the connecting rod 52 is movably connected to the bottom of the tension spring combination slider 51;

[0042] The top end of the push rod 53 abuts against the diverter block 33, and when the push rod 53 moves upward, it can squeeze the diverter block 33 to move outward;

[0043] By adopting the above scheme, when the residual material at the end of the rear mold 2 is cut by the shearing device, after the cutting knife completes cutting the residual material, the bottom of the cutting knife will abut against the tension spring combination slider 51 and push the tension spring combination slider 51 downward to make the connecting rod 52 rotate around the axis, thereby driving the push rod 53 to move upward to squeeze the diverter block 33. At this time, the diverter block 33 will push the end of the residual material in the front mold 1 out of one end of the front mold 1, thereby facilitating the shearing knife to cut the residual aluminum bar at the front mold 1.

[0044] like Figure 1 , Figure 2 , Figure 6 and Figure 8As shown, a notch is provided at one end of the connecting rod 52 located inside the front mold 1. When the front mold 1 is separated from the rear mold 2 in the initial state, the bottom end of the push rod 53 can be separated from the notch of the connecting rod 52; one end of the tension spring combination slider 51 extends to the outside of the rear mold 2 and is provided with a groove 511 with an opening facing upward;

[0045] By adopting the above solution, a notch is provided on the connecting rod 52, so that the connecting rod 52 and the bottom end of the push rod 53 can be easily separated when the front mold 1 and the rear mold 2 are separated;

[0046] At the same time, by opening a notched groove 511 on the tension spring combination slider 51, when the bottom of the shearing device is blade-shaped, the blade of the shearing device will enter the groove 511, and the slope position on the blade will abut against the tension spring combination slider 51, thereby preventing the shearing device from chipping.

[0047] like Figure 2-Figure 4 , Figure 7 , Fig. 9 and Fig.10 As shown, an aluminum rod retracting assembly 7 is elastically connected inside the annular block 6; the aluminum rod retracting assembly 7 includes an elastic block 1 71 elastically connected to the annular block 6, one end of the elastic block 1 71 extends to the inside of the front mold 1 and is movably connected to the front mold 1, and an extrusion surface 711 and an inclined block 72 are respectively provided at both ends of the elastic block 1 71, and a guide groove 74 is also provided inside the annular block 6, and a convex shaft 73 that can slide in the guide groove 74 is also fixedly connected to the elastic block 1 71, and an elastic block 2 75 is also elastically hinged inside the front mold 1, and the inclined block 72 has an overlapping portion with the elastic block 2 75 in the horizontal direction;

[0048] By adopting the above scheme, when the diverter block 33 pushes out the residual material, the inclined block 72 will squeeze and pass over the elastic block 2 75. The feeding rack for the next group of aluminum bars will first squeeze the annular block 6 to reset, so that the inclined block 72 squeezes the elastic block 2 75. Since the inclined angle of the inclined block 72 and the elastic block 2 75 relative to each other is large, and the elastic block 2 75 cannot rotate clockwise at this time, the elastic block 2 75 will force the inclined block 72 to drive the elastic block 1 71 downward and make the extrusion surface 711 squeeze the end of the residual aluminum bar material, and move the residual aluminum bar material as a whole toward the outlet of the rear mold 2. When the inclined block 72 passes over the elastic block 2 75, the elastic block 1 71 will be reset by the elastic force, and the annular block 6 will also be reset. At this time, after the end of the rear mold 2 is cut, a gap will be left between the end of the metal residual material and the end of the annular block 6, which is convenient for the entry of the next group of bars.

[0049] like Figure 4 , Figure 7 and Fig.10As shown, the front mold 1 is provided with a plug hole 14, and an isolation rod 15 is fixedly connected to the inside of the plug hole 14. One end of the isolation rod 15 extends to the inner wall of the annular block 6 and is movably connected to the inner wall of the annular block 6. One end of the isolation rod 15 extends to the end of the elastic block 71 and separates the cavity of the annular block 6 from the elastic block 71.

[0050] By adopting the above scheme, when the material rack pushes the annular block 6 to reset, the isolation rod 15 will also squeeze the bottom end of the extrusion surface 711 and isolate the bottom end of the extrusion surface 711 from the cavity of the annular block 6, so as to prevent the metal fluid from entering the gap at the bottom end of the extrusion surface 711 during the subsequent extrusion of the aluminum rod and causing the material to get stuck.

[0051] The working principle and use process of the present invention:

[0052] When the aluminum rod enters the annular block 6 from the material rack, the end of the aluminum rod will be diverted by the diverter bridge 2 34 and then diverted axially by the diverter bridge 1 32. At the same time, the diverter surface 331 will guide the metal flow overlapping with the diverter block 33 in the axial direction to the corner of the rectangular frame, and balance the metal flow through the gaps between adjacent diverter bridges 1 32 and diverter bridges 2 34. Subsequently, the diverted aluminum rod will also be guided by the guide curved surface 11 and pass through the diverter hole 13 through the welding chamber 41 to complete the welding of the diverted metal, and finally be extruded through the gap between the working belt 21 and the core body 31 to form an aluminum profile;

[0053] When the shearing device cuts the residual material at the end of the rear mold 2, after the cutting knife has completed the cutting of the residual material, the bottom of the cutting knife will abut against the tension spring combination slider 51 and push the tension spring combination slider 51 downward to make the connecting rod 52 rotate around the axis, thereby driving the push rod 53 to press the diverter block 33 upward. At this time, the diverter block 33 will push the end of the residual material in the front mold 1 out of one end of the front mold 1, so that the shearing knife can cut the residual material of the aluminum bar at the front mold 1.

[0054] When the shunt block 33 pushes out the remaining material, the annular block 6 will also move synchronously. At this time, the inclined block 72 will squeeze and pass over the elastic block 2 75. When the next group of aluminum bars needs to be loaded, the material rack will first squeeze the annular block 6 to reset, thereby causing the inclined block 72 to squeeze the elastic block 2 75. At this time, since the inclined block 72 and the elastic block 2 75 have a larger inclination angle relative to each other, and the elastic block 2 75 cannot rotate clockwise at this time, the elastic block 2 75 will force the inclined block 72 to drive the elastic block 1 71 downward and make the extrusion surface 711 extrude the end of the aluminum bar remaining material, and make the aluminum bar remaining material move as a whole toward the outlet of the rear mold 2. After the inclined block 72 passes over the elastic block 2 75, the elastic block 1 71 will be reset by the elastic force, and then the material rack will continue to push the annular block 6 to move. At this time, the isolation rod 15 will squeeze the bottom end of the extrusion surface 711 and isolate the bottom end of the extrusion surface 711 from the cavity of the annular block 6 to prevent the metal fluid from entering the gap at the bottom end of the extrusion surface 711 when the subsequent aluminum bars are extruded.
