Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy component processing, in particular to a pressing and forming die for processing an aluminum alloy pipe component. Background Art

[0002] Aluminum alloy pipe components are pipe components made of aluminum alloy materials, which are used in various fields of construction, industry and manufacturing applications; they are made of aluminum alloy materials through a series of processing processes, and have the advantages of light weight, high strength, corrosion resistance, etc.; aluminum alloy pipe components have many different types and uses, among which aluminum alloy cylinders are cylindrical components made of aluminum alloy materials, which have the characteristics of tubular shape; therefore, aluminum alloy cylinders are a type of aluminum alloy pipe components;

[0003] The impact extrusion molding machine is a common equipment for the production of aluminum alloy tubes. During the impact extrusion molding process, the aluminum alloy bar or profile is first heated by a preheating module and then placed in the die of the impact extruder. Then, by applying high pressure and impact force, the aluminum alloy material is quickly extruded into the shape of the die. The impact extrusion molding machine usually has a large impact force so that the aluminum alloy material is forced to fill the mold space to form the required tube shape. In addition, the impact extrusion molding machine has fast manufacturing speed, high production efficiency, and can manufacture aluminum alloy tubes with more complex shapes. Therefore, it is widely welcomed by small and medium-sized enterprises.

[0004] During the extrusion process of the impact extruded aluminum alloy tube, its end portion (also called the tube mouth) usually deforms or produces an irregular shape; in order to make the tube mouth have a more precise size and shape to meet specific design requirements and connection requirements, it is usually necessary to cut the tube mouth; and the cutting operation usually occurs after the impact extrusion process is completed, when the aluminum alloy tube has been cooled and reaches room temperature; the tube mouth of the aluminum alloy tube can be cut; but after the aluminum alloy tube is cooled, the aluminum alloy tube will not only be improved; the strength of the aluminum alloy tube will be increased; and the aluminum alloy tube will cause stress inside the material during the rapid cooling process; therefore, during the cutting process of the cooled aluminum alloy tube; the release of internal stress will cause bending deformation;

[0038] At this time, the user controls the driving motor 231 to operate so that the driving motor 231 can drive the cutting blade 23 to rotate; then controls the pushing unit to operate so that the pushing unit pushes the mounting column 24 to move in the direction close to the punching head 13; so that the mounting column 24 drives the cutting blade 23 rotating at the lower end to continuously approach the punching rod 133; until the cutting blade 23 contacts the aluminum alloy tube; so that the driving motor 231 can drive the cutting blade 23 to cut the end part of the aluminum alloy tube; and at this time, controls the hydraulic cylinder 121 to continue to contract; so that the hydraulic cylinder 121 can pull the mounting plate 2 up; so that the mounting plate 2 can drive the internal transmission gear ring 211 and the driving gear 22 to rise; because the driving gear 22 is connected with the screw rod 15 by helical transmission; the driving gear 22 that makes the screw rod 15 rise can rotate relative to the screw rod 15; so that the rotating driving gear 22 can drive the transmission gear ring 211 meshing with it to rotate; so that the transmission gear ring 211 drives the connecting gear 212 meshing with it to rotate through the internal teeth 213; so that the connecting gear 212 can directly drive the connecting rod 131 to rotate through the spur gear 132 meshing with it; so that the connecting rod 131 can drive the punching rod 133 to rotate simultaneously The punch rod 133 rotates in a step; during the impact extrusion process, due to the high temperature and pressure of the material, the surface of the aluminum alloy cylinder will produce a thermal bonding phenomenon when it contacts the punch rod 133; the aluminum alloy cylinder adheres to the punch rod 133 and the push block 141; so during the rotation of the punch rod 133, the punch rod 133 will drive the aluminum alloy cylinder to rotate; at this time, the cutting blade 23 cuts the rotating aluminum alloy cylinder; in order to prevent the aluminum alloy cylinder on the surface of the punch rod 133 from falling off during cutting, the hydraulic push rod 142 is controlled to push the push block 141 up; so that the push block 141 extends out of the connecting groove of the die seat 11; so that the push block 141 The moving block 141 can support the aluminum alloy cylinder; and the pushing block 141 is rotatably connected with the hydraulic push rod 142.

Moreover, the extruded aluminum alloy tube is still at a relatively high temperature, at which time the aluminum alloy tube not only has a lower hardness but is also easier to cut, thereby achieving higher cutting accuracy and surface quality. Moreover, cutting the aluminum alloy tube at a high temperature causes the thermal expansion and heat conduction of the material itself to cause the internal stress to be released faster, thereby reducing the deformation and bending of the tube during the cutting process, thereby improving the production quality of the aluminum alloy tube, and effectively improving the practical application effect of the present invention.

[0040] As an embodiment of the present invention, the pushing unit includes a rotating rod 241; a spiral groove 242 is opened on the surface of the rotating rod 241; one end of the rotating rod 241 is rotatably connected to the punch head 13, and the other end is rotatably connected to the mounting plate 2; a bevel gear shaft 243 is fixedly installed at the end of the rotating rod 241 away from the punch head 13; a bevel gear ring 244 is rotatably connected inside the mounting plate 2; the bevel gear ring 244 is spirally connected to the screw 15; the mounting column 24 is spirally connected to the rotating rod 241.

[0042] During operation, in the initial state, the projection 248 is located in the annular groove 245 close to the punch head 13; at this time, the return spring 247 located between the mounting column 24 and the punch head 13 is squeezed and in a compressed state; when the user controls the hydraulic cylinder 121 to push the mounting plate 2 down, the mounting plate 2 can drive the internal bevel gear ring 244 to descend synchronously; since the bevel gear ring 244 is connected to the screw rod 15 by a spiral transmission; the bevel gear ring 244 can rotate relative to the screw rod 15; so that the rotating bevel gear ring 244 can drive the bevel gear shaft 243 meshing with it to rotate; so that the bevel gear shaft 243 can drive the rotating rod 241 fixed to it to rotate; at this time, the projection 248 rotates in the annular groove 245; when the projection 248 rotates until the annular groove 245 and the screw rod are in contact, the bevel gear ring 244 can rotate relative to the screw rod 15; When the mounting post 24 is connected to the spiral groove 242, the mounting post 24 is pushed by the return spring 247 to drive the protrusion 248 on the inner wall of the through groove 246 to enter the spiral groove 242 through the annular groove 245; so that the protrusion 248 entering the spiral groove 242 is pushed by the inner wall of the spiral groove 242 to move in the direction away from the punch head 13; until the mounting post 24 drives the protrusion 248 to enter the annular groove 245 at one end away from the punch head 13; at this time, the return spring 247 on the side of the mounting post 24 away from the punch head 13 is located between the mounting post 24 and the mounting plate 2; and the return spring 247 is in a compressed state under the action of the blocking force of the mounting plate 2 at this time, as the rotating rod 241 continues to rotate; so that the mounting post 24 is connected to the annular groove 24 on the side away from the punch head 13 through the protrusion 248. 5; and at this time, the mounting column 24 is located directly above the storage tank 16; as the hydraulic cylinder 121 continues to push the punch head 13 and drives the punch rod 133 below to enter the connecting groove of the die seat 11; until the punch rod 133 contacts the aluminum ingot, during the process of the punch rod 133 continuously entering the connecting groove of the die seat 11; the hydraulic cylinder 121 pushes the mounting plate 2 to continuously descend and approach the machine body 1; so that the mounting plate 2 drives the cutting blade 23 below to continuously approach the machine body 1; because the cutting blade 23 is located directly above the storage tank 16; the cutting blade 23 can enter the storage tank 16, thereby avoiding the cutting blade 23 from contacting the machine body 1; preventing the cutting blade 23 pushed downward by the mounting plate 2 from being broken or bent due to being blocked by the machine body 1; thereby ensuring the cutting The normal use of the cutting blade 23 effectively improves the practical application effect of the present invention. When the punching rod 133 completes the pressing of the aluminum ingot in the die seat 11, the hydraulic cylinder 121 contracts. At this time, the hydraulic cylinder 121 pulls the mounting plate 2 up, so that the mounting plate 2 drives the internal bevel gear ring 244 to rotate in the opposite direction relative to the screw rod 15. The bevel gear ring 244 rotating in the opposite direction can drive the bevel gear shaft 243 to drive the rotating rod 241 to rotate in the opposite direction. The rotating rod 241 rotating in the opposite direction can drive the annular groove 245 in the spiral groove 242 to rotate in the opposite direction. At this time, the protrusion 248 rotates in the annular groove 245. When the hydraulic cylinder 121 drives the punching rod 133 at the lower end to extend out of the connecting groove of the die seat 11, the mounting plate 2 drives the cutting blade 23 to extend out of the storage groove 16.At this time, the protrusion 248 rotates to the connection between the spiral groove 242 and the annular groove 245; due to the action of the reset spring 247, the reset spring 247 pushes the mounting column 24 and drives the protrusion 248 to enter the spiral groove 242; the protrusion 248 is pushed by the inner wall of the spiral groove 242 and moves toward the direction close to the punch head 13; at this time, by controlling the operation of the drive motor 231, the drive motor 231 can drive the lower end of the cutting blade 23 to rotate; before the cutting blade 23 contacts the aluminum alloy cylinder, the hydraulic push rod 142 pushes the aluminum alloy cylinder to continuously rise and extend out of the connecting groove; then the cutting blade 23 contacts the aluminum alloy cylinder and cuts the end part of the aluminum alloy cylinder. ;

[0043] As an embodiment of the present invention, a groove 17 is provided at the lower end of the punch head 13; the punch rod 133 is slidably connected in the groove 17; a cylindrical groove 171 is provided at the bottom of the groove 17; the punch rod 133 is fixedly connected to the bottom of the cylindrical groove 171 through a support spring 172.

[0046] During operation, during the cutting process of the cutting blade 23, the cutting blade 23 needs to cut and separate the end part of the aluminum alloy tube; so the cutting blade 23 needs to cut into the inner wall of the aluminum alloy tube; at this time, the cutting blade 23 will cut into the surface of the punching rod 133; thereby cutting a ring-shaped cutting opening on the surface of the punching rod 133; when the aluminum ingot with the ring-shaped cutting opening is pressed, the pressed aluminum ingot will enter the ring-shaped cutting opening on the surface of the punching rod 133 under the obstruction of the inner wall of the connecting groove 246, making it difficult for the cutting blade 23 to completely cut off the part of the aluminum alloy tube entering the ring-shaped cutting opening; and thus it is difficult to cause the aluminum alloy tube to be completely separated; for this purpose, the present invention sets a groove 17; so that in the initial state, the end of the punching rod 133 connected to the support spring 172 is located in the groove 17; when the hydraulic cylinder 121 pushes the punching rod 133 down, the punching rod 133 will enter the connecting groove of the mold seat 11; so that the punching rod 1 33 first contacts the aluminum ingot; then the hydraulic cylinder 121 pushes the punch head 13 to continuously descend; so that the punch head 13 approaches the punch rod 133; so that the punch head 13 can drive the internal cylindrical groove 171 to continuously approach the punch rod 133; so that the punch rod 133 moves relative to the punch head 13 into the cylindrical groove 171; so that the punch rod 133 squeezes the support spring 172 and enters the cylindrical groove 171, when the punch rod 133 completely enters the cylindrical groove 171 When the punching rod 133 is in close contact with the punching head 13, the punching head 13 pushes the punching rod 133 to press the aluminum ingot in the connecting groove. Since the punching head 13 presses the aluminum ingot by pushing the punching rod 133, the punching head 13 and the punching rod 133 are pressed tightly, which greatly reduces the gap between the punching rod 133 and the punching head 13, thereby preventing the pressed aluminum ingot from entering between the punching rod 133 and the punching head 13 due to extrusion deformation.

[0047] In addition, the upper end of the punching rod 133 cooperates with the groove 17; so that when the hydraulic cylinder 121 pushes the mounting plate 2 down, the driving gear 22 in the mounting plate 2 will drive the transmission gear ring 211 to rotate; so that the transmission gear ring 211 can drive the spur gear 132 to rotate through the internal teeth 213 and the connecting gear 212; at this time, the spur gear 132 drives the punching rod 133 to rotate through the groove 17 in the punching head 13; when the punching rod 133 squeezes the support spring 172 to enter the cylindrical groove 171, at this time, the punching rod 133 rotates in the cylindrical groove 171 relative to the punching head 13; when the pressing is completed; the hydraulic cylinder 121 pulls the punching head 13 up; at this time, the punching rod 133 moves from the cylindrical groove 171 to the groove 17 direction under the push of gravity, that is, the restoring force of the support spring 172; when the punching rod 133 and the groove 17 port contact; at this time, as the punch head 13 rises; the punch head 13 will rotate under the drive of the transmission gear ring 211; until the punch rod 133 cooperates with the groove 17; at this time, the punch rod 133 completely enters the groove 17; and at this time, there is a separation gap at the connection between the punch rod 133 and the punch head 13; then when the cutting blade 23 cuts the aluminum alloy cylinder; the part where the cutting blade 23 cuts into the inner wall of the aluminum alloy cylinder is just located between the connection and separation gap between the punch rod 133 and the punch head 13; thereby avoiding the cutting blade 23 from cutting the surface of the punch rod 133 to produce a cutting opening; preventing the cutting blade 23 from being unable to completely cut the part of the aluminum alloy that is squeezed and enters the cutting opening; thereby ensuring that the cutting blade 23 can completely cut and separate the end part of the aluminum alloy cylinder; thereby effectively improving the practical application effect of the present invention;

[0048] When the cutting blade 23 cuts the aluminum alloy cylinder, the metal particles generated by the cutting will be sputtered outward in the form of sparks; in order to prevent the metal particles at the cutting sputtering from adhering to the thread groove on the surface of the screw 15; causing the metal particles in the thread groove on the surface of the screw 15 to block the spiral transmission connection between the bevel gear ring 244 or the drive gear 22 and the screw 15; therefore, the present invention provides a bellows 26; so that the bellows 26 can be sleeved on the surface of the screw 15; so that the bellows 26 can prevent the sputtered metal particles from adhering to the surface of the screw 15; thereby ensuring that the bevel gear ring 244 or the drive gear 22 can stably connect with the screw The rod 15 is connected by a spiral transmission; the practical application effect of the present invention is improved; and the sputtered metal particles will also enter the storage tank 16; on the one hand, it is difficult to clean the metal particles entering the storage tank 16; thus, it will increase the difficulty of cleaning for the staff; on the other hand, the metal particles are accumulated in the storage tank 16; when the cutting blade 23 enters the storage tank 16, the cutting blade 23 and the metal particles entering the storage tank 16 are squeezed against each other; thus, the cutting blade 23 is squeezed by the metal particles and is bent and deformed; therefore, the present invention sets a baffle 161; so that the baffle 161 can be connected to the spring The spring 162 pushes the notch located in the storage tank 16, so that the baffle 161 can block the sputtered metal particles and prevent the metal particles from entering the storage tank 16. The upper end surface of the baffle 161 is set as an arc surface, and the baffle 161 is made of PTFE material, so that the upper end surface of the baffle 161 is smooth, so that the metal particles falling on the baffle 161 will roll along the arc surface, and also prevent the metal particles from adhering to the surface of the baffle 161. The setting of the rack 25 is that when the hydraulic cylinder 121 pushes the mounting plate 2 downward, the column slot 171 drives the cutting blade 23 to the rack 25. At this time, the column The protrusion 248 in the cylindrical groove 171 is located in the annular groove 245 away from the punch head 13; when the mounting plate 2 pushes the cylindrical groove 171 to move downward; the mounting plate 2 will drive the lower end of the storage rack 25 to descend; so that the storage rack 25 drives the upper end of the mounting column 24 and pushes the baffle 161 to squeeze the connecting spring 162 into the storage groove 16; avoid the mounting column 24 driving the lower end of the cutting blade 23 to directly contact the baffle 161; avoid the cutting blade 23 being blocked by the arc surface of the baffle 161 and causing bending and deformation problems; thereby achieving protection for the cutting blade 23; so that the practical application effect of the present invention is further improved.
