DETAILED DESCRIPTION

[0061] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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.

[0062] As described in the background technology, before extrusion molding, the aluminum alloy material needs to be heated to a certain temperature to enhance its plasticity. When the aluminum alloy grounding body is processed by the traditional aluminum alloy grounding body automatic extrusion molding equipment, the impact head is in contact with the high-temperature aluminum alloy material and heated. If the impact head cannot be cooled in time, it will cause the impact head to overheat, making the impact head prone to deformation, seriously affecting the qualified rate of the finished product. Therefore, how to dissipate heat from the impact head in time has become a technical problem that needs to be solved urgently by those skilled in the art.

[0063] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The present invention provides an automatic extrusion forming device for an aluminum alloy grounding body, comprising a die seat 110, an impact rod 120 and a cooling head 130. A positioning hole 111 for accommodating the aluminum alloy material to be extruded is formed in the middle of one side of the die seat 110. An impact head is formed at one end of the impact rod 120 facing the positioning hole 111. The impact head can move toward or away from the positioning hole 111. The cooling head 130 is sleeved on the impact head for cooling the impact head. When the impact head moves toward the positioning hole 111, the moving speed of the cooling head 130 is greater than that of the impact head and is separated from the impact head. When the impact head moves away from the positioning hole 111, the cooling head 130 moves away from the positioning hole 111 and is gradually sleeved on the impact head. In this way, the impact head can be effectively dissipated in the stamping gap, the impact head is prevented from being overheated and deformed, and the qualified rate of the finished product is guaranteed. A coolant flow cavity 131 is formed inside the cooling head 130. The automatic extrusion forming device for an aluminum alloy grounding body also includes a fixing seat 140 and a rotating drum 150. The fixed seat 140 is arranged opposite to the die seat 110. The rotating drum 150 is arranged between the die seat 110 and the fixed seat 140, one end of which is rotatably connected to the die seat 110, and the other end of which is rotatably connected to the fixed seat 140, and a clearance cavity for the impact rod 120 to pass through is formed inside. An upper coolant storage cavity 151 connected to the coolant flow cavity 131 is arranged inside the top of the rotating drum 150, and a lower coolant storage cavity 152 connected to the coolant flow cavity 131 is arranged inside the bottom. The coolant from the upper coolant storage cavity 151 flows through the coolant flow cavity 131 into the lower coolant storage cavity 152 to achieve the purpose of cooling the impact head. Door holes 159 for the aluminum alloy material to be extruded to pass through are respectively opened on opposite sides of the rotating drum 150, so as to facilitate the aluminum alloy material to be extruded to be placed in the positioning hole 111. The coolant flows through the cavity 131 and is connected to the upper coolant storage cavity 151 through the upper telescopic tube 161, and the coolant flows through the cavity 131 and is connected to the lower coolant storage cavity 152 through the lower telescopic tube 162, so that the coolant flows through the upper coolant storage cavity 151 and the coolant flows through the cavity 131 in turn and then flows into the lower coolant storage cavity 152.

[0064] Preferably, the upper telescopic tube 161 and the lower telescopic tube 162 are stainless steel telescopic tubes or flexible bellows.

[0065] Specifically, in the example, Figure 3 and Figure 4As shown, a receiving chamber 141 is formed inside the fixing seat 140. The automatic extrusion molding equipment for aluminum alloy grounding body also includes a first transmission assembly 170. The first transmission assembly 170 is installed in the receiving chamber 141 and is connected to the impact rod 120 and the rotating drum 150 respectively. When the impact head moves toward the positioning hole 111, the rotating drum 150 does not rotate. When the impact head moves away from the positioning hole 111, the impact rod 120 drives the rotating drum 150 to rotate through the first transmission assembly 170, so that the orientation of the upper coolant storage chamber 151 and the lower coolant storage chamber 152 are reversed. In this way, the coolant can be recycled. The first transmission assembly 170 includes a rack 171, a gear 172, a first rotating shaft 173, a one-way bearing, a first pulley 174, a second rotating shaft 175, a second pulley 176, a belt 177, a worm 178 and a gear ring 179. The rack 171 is installed on a side surface of the impact rod 120 along the axial direction of the impact rod 120. The side wall of the gear 172 is meshed with the rack 171. The axis of the first rotating shaft 173 is vertically arranged, and the bottom end is rotatably connected to the bottom of the accommodating chamber 141. The one-way bearing is sleeved on the upper part of the first rotating shaft 173, and the gear 172 is sleeved on the outside. The first pulley 174 is sleeved on the lower part of the first rotating shaft 173. The axis of the second rotating shaft 175 is vertically arranged, and the bottom end is rotatably connected to the bottom of the accommodating chamber 141. The second pulley 176 is sleeved on the lower part of the second rotating shaft 175. The belt 177 is wound around the first pulley 174 and the second pulley 176. The axis of the worm 178 is vertically arranged, and the bottom end is fixed to the top of the second rotating shaft 175. The gear ring 179 is sleeved on one end of the rotating drum 150 close to the fixed seat 140, and the outer wall is meshed with the worm 178. When the impact head moves toward the positioning hole 111, the first rotating shaft 173 does not rotate. When the impact head moves away from the positioning hole 111, the gear 171, the gear 172, the first rotating shaft 173, the one-way bearing, the first pulley 174, the second rotating shaft 175, the second pulley 176, the belt 177 and the worm 178 drive the gear ring 179 to rotate, and then drive the rotating drum 150 to rotate, so that the positions of the upper coolant storage chamber 151 and the lower coolant storage chamber 152 are reversed.

[0066] Specifically, in the example, Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the automatic extrusion molding equipment for aluminum alloy grounding body further includes a second transmission assembly 180. The second transmission assembly 180 is arranged in the drum 150, connected to the cooling head 130, and can drive the cooling head 130 to move. An upper hydraulic oil storage chamber 153 and an upper hydraulic oil flow chamber are arranged in the top of the drum 150, and a lower hydraulic oil storage chamber 155 and a lower hydraulic oil flow chamber 156 are arranged in the bottom. An upper guide groove 157 is arranged on the inner wall of the top of the drum 150, and a lower guide groove 158 is arranged on the inner wall of the bottom. The second transmission assembly 180 includes an upper spring 1811, an upper pressure plate 1821, an upper pressure seat 1831, a first upper ball, a second upper ball 1851, an upper cross bar 1861, an upper vertical bar 1871, a lower spring 1812, a lower pressure plate 1822, a lower pressure seat 1832, a first lower ball 1842, a second lower ball 1852, a lower cross bar 1862 and a lower vertical bar 1872. Hydraulic oil is stored in the upper hydraulic oil storage chamber 153. The upper spring 1811 is vertically installed in the upper hydraulic oil storage chamber 153. The upper pressure plate 1821 is installed at the bottom end of the upper spring 1811. The top end of the upper pressure seat 1831 is installed at the bottom end of the upper pressure plate 1821, and the bottom end abuts against the top side of the impact rod 120. The first upper ball is installed in the upper hydraulic oil flow chamber. The second upper ball 1851 is installed in the upper guide groove 157. One end of the top surface of the upper cross bar 1861 is fixedly connected to the first upper ball, and the other end of the top surface is slidably connected to the second upper ball 1851. The top end of the upper vertical rod 1871 is fixedly connected to the middle of the bottom end of the upper cross bar 1861, and the bottom end is fixedly connected to the upper side of the cooling head 130. Hydraulic oil is also stored in the lower hydraulic oil storage chamber 155. The lower spring 1812 is vertically installed in the lower hydraulic oil storage chamber 155. The lower pressure plate 1822 is installed at the top end of the lower spring 1812. The bottom end of the lower pressure seat 1832 is installed at the top end of the lower pressure plate 1822, and the top end abuts against the bottom side of the impact rod 120. The first lower ball 1842 is installed in the lower hydraulic oil flow chamber 156. The second lower ball 1852 is installed in the lower guide groove 158. One end of the bottom surface of the lower cross bar 1862 is fixedly connected to the first lower ball 1842, and the other end of the bottom surface is slidably connected to the second lower ball 1852. The bottom end of the lower vertical rod 1872 is fixedly connected to the middle of the top end of the lower cross bar 1862, and the top end is fixedly connected to the lower side of the cooling head 130. It should be noted that Figure 2As shown, the cross-sectional diameter of the end of the impact rod 120 close to the impact head is smaller than the cross-sectional diameter of the end of the impact rod 120 away from the impact head, and an inclined surface is provided at the connection. Correspondingly, transition inclined surfaces are provided at the bottom of the upper pressure seat 1831 and the top of the lower pressure seat 1832, respectively. When the impact head moves toward the positioning hole 111, the upper pressure seat 1831 is forced to move upward, and the lower pressure seat 1832 is forced to move downward, driving the upper pressure plate 1821 to move upward, and driving the lower pressure plate 1822 to move downward. The hydraulic oil in the upper hydraulic oil storage chamber 153 flows into the upper hydraulic oil flow chamber, and impacts the first upper ball to move along the upper hydraulic oil flow chamber, and the upper cross bar 1861 and the second upper ball 1851 move along the upper guide groove 157 to drive the upper vertical bar 1871 and the cooling head 130 to move. At the same time, the hydraulic oil in the lower hydraulic oil storage chamber 155 flows into the lower hydraulic oil flow chamber 156, and impacts the first lower ball 1842 to move along the lower hydraulic oil flow chamber 156, and the lower cross bar 1862 and the second lower ball 1852 move along the lower guide groove 158 to drive the lower vertical rod 1872 and the cooling head 130 to move. In this way, the movement speed of the cooling head 130 can be greater than that of the impact head and can be separated from the impact head. When the impact head moves away from the positioning hole 111, the upper pressure plate 1821 and the upper pressure seat 1831 are driven to move downward with the help of the force of the upper spring 1811 to restore the deformation. With the help of the force of the lower spring 1812 to restore the deformation, the lower pressure plate 1822 and the lower pressure seat 1832 are driven to move upward. The hydraulic oil in the upper hydraulic oil flow chamber flows back to the upper hydraulic oil storage chamber 153, the first upper ball moves and resets along the upper hydraulic oil flow chamber, the upper cross bar 1861 and the second upper ball 1851 move along the upper guide groove 157, so as to drive the upper vertical rod 1871 and the cooling head 130 to move and reset. At the same time, the hydraulic oil in the lower hydraulic oil flow chamber 156 flows back to the lower hydraulic oil storage chamber 155, the first lower ball 1842 moves and resets along the lower hydraulic oil flow chamber 156, the lower cross bar 1862 and the second lower ball 1852 move along the lower guide groove 158, so as to drive the lower vertical rod 1872 and the cooling head 130 to move and reset. In this way, the cooling head 130 can be gradually sleeved on the heated impact head to cool the impact head.

[0067] Preferably, the upper guide groove 157 includes an upper straight guide section and an upper oblique guide section that are connected. The lower guide groove 158 includes a lower straight guide section and a lower oblique guide section that are connected. In this way, when the cooling head 130 is separated from the impact head, the movement trajectory of the impact head can be avoided to ensure that the stamping work is carried out normally.

[0068] Specifically, in the example, Figure 1As shown, the automatic extrusion molding device for aluminum alloy grounding body further includes a linear drive 191 and a workbench 192. The output shaft of the linear drive 191 is fixedly connected to the end of the impact rod 120 away from the impact head, and is used to drive the impact rod 120 to perform linear reciprocating motion. The die holder 110 and the linear drive 191 are installed on the top surface of the workbench 192.

[0069] Preferably, the linear drive 191 is an electric push rod or a hydraulic cylinder or the like.
