Description

Technical Field

[0001] The present invention relates to the technical field of extrusion molding, and more specifically, to an aluminum profile extrusion molding process and equipment. Background Art

[0002] Extrusion molding is usually a process in which a solid punch pushes aluminum through a die, allowing the aluminum to be extruded from the die hole and formed. It can be understood as squeezing a toothpaste tube by hand, and when squeezing, the toothpaste will flow out in the shape of the tube hole. The opening of the toothpaste tube mainly plays the same role as the extrusion die. Direct extrusion is the most commonly used method for extruding aluminum profiles. People also call this method a forward extrusion process. The extrusion speed is directly related to the metal pressure and temperature in the container. Therefore, the speed, pressure and temperature must be properly related to maintain a stable process and produce a constant extrusion section. If the temperature is too high, the metal fluidity will increase, and ultimately the metal cannot enter the narrow area. At the same time, too high a temperature will also cause tearing at sharp corners and thin edges during the molding process, affecting the yield rate; if the temperature is not enough, the aluminum may cool to room temperature during the process of being placed in the extrusion equipment, resulting in the need for greater pressure for extrusion, increasing the energy consumption of extrusion. Therefore, it is necessary to keep the temperature moderate during the production process and keep the temperature constant as much as possible during the extrusion process. Therefore, how to maintain the temperature during extrusion is the technical problem to be solved by the present invention. Summary of the invention

DETAILED DESCRIPTION

[0053] like Figure 1-Figure 10 As shown, the present invention provides an aluminum profile extrusion forming device, comprising: a pretreatment module, used for pretreatment of an aluminum rod 100 and an extrusion die 23;

The second cutting device 25 is located between the first guiding device 24 and the extrusion die 23 and is used to cut off the extruded product 101. After cutting, the extruded product 101 connected to the first guiding device 24 is a primary product 102.

[0058] The processing module is composed of a second guiding device 31 and a stretching device 32 clamped at both ends of the primary product 102, a third cutting device 33, and a heat treatment box 34. The second guiding device 31 and the stretching device 32 are used to guide the primary product 102 to leave the extrusion module 2. The stretching device 32 is used to stretch the primary product 102 to make a secondary product 103. The third cutting device 33 is used to cut the secondary product 103 into tertiary products 104. The heat treatment box 34 is used to heat treat the tertiary product 104 to make a finished product 105.

[0059] At the same time, if Figure 1 As shown, the present invention also provides an aluminum profile extrusion molding process, using the above aluminum profile extrusion molding equipment, the processing steps are as follows

[0060] S1: pre-treating the aluminum rod 100 and the extrusion die 23;

[0061] S101: sending the aluminum rod 100 into the first preheating device 11 for heating, and sending the extrusion die 23 into the second preheating device 12 for heating;

[0062] S102: the preheated aluminum rod 100 is cut into sections of the preheated aluminum rod 100 by the first cutting device 13 and sent to the extrusion module 2;

[0063] S2: Extruding the pretreated aluminum rod 100 into a primary product 102;

[0064] S201: placing the preheated extrusion die 23 into the cavity 21;

[0065] S202: placing the preheated aluminum rod 100 into the mold cavity 21;

[0066] S203: the pushing device 22 pushes the material block 221 in the cavity 21, and the material block 221 pushes the aluminum rod 100 to contact the extrusion die 23, and is extruded out of the cavity 21 to form an extruded product 101;

[0067] S204: the extruded product 101 moves under the guidance of the first guiding device 24. After the length reaches the standard, the second cutting device 25 cuts the extruded product 101 to obtain a primary product 102.

[0068] S3: manufacturing the primary product 102 into a finished product 105;

[0069] S301: The primary product 102 is moved from the first guiding device 24 to the second guiding device 31 and the stretching device 32, and is sent to the processing position by the second guiding device 31 and the stretching device 32;

[0070] S302: The stretching device 32 stretches the primary product 102 to obtain a secondary product 103;

[0071] S303: The third cutting device 33 cuts the secondary product 103 into a plurality of tertiary products 104 of the same length according to the production standard;

[0072] S304: After the tertiary products 104 are stacked according to the internal shape of the heat treatment box 34, they are sent into the heat treatment box 34 for heat treatment;

[0073] S305: After heat treatment, the finished product 105 is obtained.

[0074] The working principle and beneficial effects of the above technical solution: In the present invention, the aluminum rod 100 and the extrusion die 23 are preheated respectively by the first preheating device 11 and the second preheating device 12 in the pretreatment module, so as to ensure that a certain extrusion temperature can be maintained in the extrusion module 2 to avoid the situation where the temperature is too low, and at the same time, the temperature difference between the aluminum rod 100 and the extrusion die 23 is also avoided. During the extrusion process, the extrusion die 23 will also generate heat due to friction to avoid temperature reduction. After the aluminum rod 100 is preheated, the temperature can be maintained stable before the end of extrusion to avoid temperature reduction, thereby achieving the effect of maintaining the extrusion temperature during the extrusion process.

[0075] During the extrusion process, in addition to temperature, pressure and advancement speed will also affect the shape of the extruded product 101. Therefore, the extruded product 101 is prone to poor flatness during the extrusion process. The usual practice is to repair it through shaping, which will greatly increase the manufacturing cost and production cycle. Therefore, at the two deformation nodes where flatness problems are prone to occur, that is, when the aluminum rod 100 is extruded into the extruded product 101, and when the stretching device 32 stretches the primary product 102 into the secondary product, a surface adjustment component is added to immediately adjust the flatness after the extrusion and stretching deformation is completed, thereby avoiding the problem of poor flatness, thereby reducing the repair rate, improving production efficiency, and reducing production costs. In this embodiment, Figure 2As shown, the extrusion module 2 is provided with a first surface adjustment component 4, and the processing module is provided with a second surface adjustment component 5. After the aluminum rod 100 is extruded and formed by the extrusion die 23, it is firstly subjected to the first surface adjustment component 4 for the first surface shaping to form a primary product 102. The number of the first surface adjustment components 4 is usually determined according to the number of outer surfaces of the extruded product 101. For example, if the extruded product 101 has three outer surfaces and its cross section is triangular, three first surface adjustment components 4 are provided. If the extruded product 101 has four outer surfaces and its cross section is rectangular, four first surface adjustment components 4 are provided. If the extruded product 101 has one or more surfaces and its cross section is circular or polygonal, the first surface adjustment component 4 can be structurally optimized. For details, see the following embodiment. Before the primary product 102 is made into a finished product 105 in the processing module, it is subjected to the second surface shaping by the second surface adjustment component 5 to form a finished product 105. The number and setting method of the second surface adjustment component 5 are the same as those of the first surface adjustment component 4.

[0076] Similarly, because the first surface adjustment component 4 and the second surface adjustment component 5 are added, the corresponding molding process is further optimized, wherein step S204 further includes:

[0077] S2041: After the extruded product 101 is extruded, the end of the extruded product 101 passes through the first surface adjustment component 4, the spray system, the second cutting device 25 in sequence and reaches the first guiding device 24;

[0078] S2042: The first guiding device 24 guides the extruded product 101 that has undergone the first shaping and spray cooling to move;

[0079] S2043: After the length reaches the standard, the second cutting device 25 cuts the extruded product 101 to obtain a primary product 102;

[0080] Step S302 also includes:

[0081] S3021: The stretching device 32 stretches the primary product 102;

[0082] S3022: The second surface adjustment component 5 performs a second surface shaping on the elongated primary product 102 to obtain a secondary product 103.

[0083] Because after the extruded product 101 comes out of the extrusion die 23, under the dual effects of the traction of the first guide device 24 and the continuous pushing of the pushing device 22, the extruded product 101 is in continuous linear motion. In order to avoid the first surface adjustment component 4 from affecting the extrusion speed, etc., the first surface adjustment component 4 usually adopts a cylindrical structure, so that the first surface adjustment component 4 fits on the outer surface of the extruded product 101 and can roll relative to the extruded product 101. The first surface adjustment components 4 are usually arranged relatively to each other, so that the surface of the extruded product 101 is shaped by a fixed distance between two first surface adjustment components 4. On this basis, the first surface adjustment component 4 is composed of an abutting tube 41 abutting the outer surface of the extruded product 101, an eccentric tube 42 arranged in the abutting tube 41, and an eccentric shaft 43 arranged in the eccentric tube 42. The outer wall shape of the abutting tube 41 can be set according to the shape of the extruded product 101. For example, the abutting tube 41 can be cylindrical, which is used for the extruded product 101 with a flat surface, or it can be an hourglass shape with wide ends and narrow in the middle, which is used for the extruded product 101 with a curved surface. The abutting tube 41 is mainly used to abut against the surface of the extruded product 101 to shape the surface. The two ends of the eccentric tube 42 are provided with shaft covers 44, and the two ends of the eccentric shaft 43 are movably connected with the two shaft covers 44. The eccentric shaft 43 is semi-cylindrical, so as to achieve the effect of eccentric rotation. Figure 6-8 As shown, both ends of the abutting tube 41 are provided with sealing covers 45 movably connected to the outer wall of the shaft cover 44, so that the eccentric tube 42 can be enclosed in the abutting tube 41, one of the shaft covers 44 is connected to the driving device, the eccentric tube 42 can be cylindrical, and an eccentric block is provided on the outer wall of the eccentric tube 42, thereby achieving an eccentric effect. It should be noted that, regardless of whether an eccentric block is provided, the end with a larger weight should be located on the side close to the extruded product 101 through the driving device, for example Figure 5 As shown, the eccentric block is always located on one side of the extruded product 101, so that when the eccentric tube 42 rotates rapidly, a force can be applied to the surface of the extruded product 101, thereby further shaping the surface of the extruded product 101. The abutting tube 41, the eccentric tube 42 and the eccentric shaft 43 have the same rotation center axis, and the inner wall of the eccentric tube 42 is provided with a clamping table 46, and the clamping table 46 abuts against the eccentric shaft 43. By providing the clamping table 46, the first surface adjustment component 4 can realize the selection of two surface adjustment forces, low force and high force. For example, when performing a low-force adjustment, the driving device drives the eccentric tube 42 to rotate, and its rotation direction causes the semi-cylindrical eccentric shaft 43 to abut against one side of the clamping table 46. At this time, the center of gravity of the eccentric shaft 43 does not coincide with the center of gravity of the eccentric tube 42, as shown in FIG. Figure 8As shown in FIG. DD, when high-force adjustment is required, the driving device drives the eccentric tube 42 to rotate in the opposite direction, so that the eccentric shaft 43 abuts against the other side of the clamping table 46. At this time, the center of gravity of the eccentric shaft 43 coincides with the center of gravity of the eccentric tube 42, as shown in FIG. Figure 8 As shown in EE, through the design of the above structure, the force acting on the surface of the extruded product 101 by the eccentric tube 42 can be changed by changing the rotation direction of the eccentric tube 42, and the surface adjustment force can be adjusted according to the thickness of the extruded product 101.

[0084] Different from the continuous material transportation of the first deformation of the aluminum rod 100 (deformation of the aluminum rod 100 into the extruded product 101 through the extrusion module 2), the length of the primary product 102 itself is cut by the second cutting device 25, and the two ends are fixed by the stretching device 32 and the second guide device 31, so after it is stretched, it is usually directly sent to the third cutting device 33 for cutting, so the primary product 102 itself will not be in a translational state like the extruded product 101, and therefore the stretched primary product 102 can be subjected to a second surface shaping by the second surface adjustment component 5 and transported to the third cutting device 33 for cutting. Therefore, the second surface adjustment component 5 needs to have the functions of surface adjustment and transportation. It should be noted that the transportation function and the surface adjustment function are independent of each other, and the second surface adjustment component 5 does not have to have the ability to transport the primary product 102. In order to achieve the effects of surface adjustment and conveying at the same time, the second surface adjustment component 5 is composed of a fixing portion 51, a horizontal displacement component 52 arranged on the fixing portion 51, a vertical displacement component 53 arranged in the horizontal displacement component 52, a surface bonding plate 54 arranged on the vertical displacement component 53, and an eccentric wheel 55 connected to the axis of the vertical displacement component 53. The cross section of the horizontal displacement component 52 is C-shaped, as shown in FIG. Fig. 9As shown, its opening is located at the top of the horizontal displacement assembly 52, and the vertical displacement assembly 53 is provided with a driving device for driving the eccentric wheel 55 to rotate. The surface bonding plate 54 is located above the horizontal displacement assembly 52, and penetrates the horizontal displacement assembly 52 from the top opening of the horizontal displacement assembly 52 through the connecting column 541, and is connected to the top of the vertical displacement assembly 53. The shape of the surface bonding plate 54 is adapted to the surface of the primary product 102. The horizontal displacement assembly 52 is movably connected to the fixing portion 51 through at least two first reset assemblies, and the vertical displacement assembly 53 is movably connected to the horizontal displacement assembly 52 through at least two second reset assemblies. The two first reset assemblies are respectively a left reset member 56 and a right reset member 57, and the two second reset assemblies are respectively an upper reset member 58 and a lower reset member 59. The upper reset member 58 is located between the top surface of the vertical displacement assembly 53 and the inner top surface of the horizontal displacement assembly 52, and the lower reset member 59 is located between the bottom surface of the vertical displacement assembly 53 and the inner bottom surface of the horizontal displacement assembly 52. Usually the cross section of the vertical displacement assembly 53 is rectangular, such as Fig. 9 As shown, two limit columns are respectively provided at the top and bottom of the vertical displacement component 53, which are two upper limit columns and two lower limit columns. The second reset component is usually four, namely two upper reset members 58 and two lower reset members 59, which are all sleeved on the outside of the limit columns. The vertical displacement component 53 is connected to the inner wall of the horizontal displacement component 52 through the upper reset member 58 and the lower reset member 59. The end faces of the upper and lower limit columns do not contact the inner wall of the horizontal displacement component 52. At the same time, a gap is left so that the vertical displacement component 53 can move up and down, thereby driving the surface bonding plate 54 to move up and down. The fixing portion 51 is provided with two parallel limit plates, namely a left limit plate 511 and a right limit plate 512. The horizontal displacement assembly 52 is located between the two limit plates, and limit columns are provided on two surfaces opposite to the two limit plates, namely a left limit column 521 provided with a left reset member 56, and a right limit column 522 provided with a right reset member 57. The left limit column 521 penetrates the left limit plate 511 and is movably connected to the left limit plate 511. The left reset member 56 is located between the left limit plate 511 and the horizontal displacement assembly 52. ​​The right limit column 522 penetrates the right limit plate 512 and is movably connected to the right limit plate 512. The right reset member 57 is located between the right limit plate 512 and the horizontal displacement assembly 52.

[0085] When the second surface adjustment assembly 5 is not started and the eccentric wheel 55 is located away from the primary product 102 , the forces on the left and right reset members and the upper and lower reset members are in a balanced state, and the surface bonding plate 54 is not bonded to the surface of the primary product 102 .

[0086] After the second surface adjustment assembly 5 is started, take the example of the driving device driving the eccentric wheel 55 to rotate counterclockwise. Fig.10As shown in FIG. 1 , when it rotates counterclockwise to a horizontal left position, the vertical displacement assembly 53 is driven downward by the eccentric wheel 55, pressing the lower reset member 59 and stretching the upper reset member 58. At the same time, the horizontal displacement assembly 52 translates to the left relative to the fixing portion 51, squeezing the left reset member 56 and stretching the right reset member 57, thereby causing the surface bonding plate 54 to move downward and leftward, as shown in FIG. Fig.10 As shown, separation from the surface of the primary product 102 is achieved, and the surface bonding plate 54 is located at the far left end.

[0087] As the eccentric wheel 55 continues to rotate counterclockwise, when it rotates to the bottom, the lower reset member 59 is pressed to the lowest point. If a lower limit column is provided, the lower limit column abuts against the inner bottom surface of the horizontal displacement assembly 52 for limiting, and the surface bonding plate 54 is located at the lowest end. Then the eccentric wheel 55 continues to rotate counterclockwise. When it rotates to the right, the horizontal displacement assembly 52 squeezes the right reset member 57 and stretches the left reset member 56, and the surface bonding plate 54 is located at the rightmost end. When it rotates to the top, the upper reset member 58 is squeezed to the limit, and the surface bonding plate 54 squeezes the surface of the primary product 102 to perform a second surface shaping. When it rotates to the right, it drives the primary product 102 to move to the left until the eccentric wheel 55 rotates to the left and the surface bonding plate 54 separates.

[0088] In this embodiment, the surface shaping is performed multiple times by the surface bonding plate 54 to ensure the uniformity of the surface shaping, and at the same time, the primary product 102 can be driven to translate.
