[0030] In this embodiment, a servo motor is provided inside the installation box 1, and the rotating shaft 2 passes through the top of the installation box 1 and is fixedly connected to the servo motor inside the installation box 1. Because the rotating shaft 2 is fixedly connected to the servo motor inside the installation box 1, when the servo motor is started, the servo motor will drive the rotating shaft 2 to rotate together.

[0031] In this embodiment, the connection point between the rotating shaft 2 and the rotating rod 3 is located at the center point of the rotating rod 3. The rotating rod 3 forms a rotating structure through the rotating shaft 2. Because the rotating shaft 2 and the rotating rod 3 are fixedly connected, when the rotating shaft 2 rotates, it will drive the rotating rod 3 to rotate clockwise.

[0032] In this embodiment, two groups of sliding columns 4 are provided, and the two groups of sliding columns 4 are respectively provided at the two ends of the rotating rod 3. Because the two groups of sliding columns 4 are respectively provided at the two ends of the rotating rod 3, when the rotating rod 3 rotates, the two groups of sliding columns 4 will be driven to rotate together.

[0033] In this embodiment, two groups of transmission plates 5 are symmetrically arranged, and the tops of the two groups of transmission plates 5 are opened with horizontally arranged sliding grooves. The two groups of sliding columns 4 are respectively embedded in the sliding grooves of the two groups of transmission plates 5 and are slidably connected with the transmission plates 5. Since the two groups of sliding columns 4 are respectively embedded in the sliding grooves of the transmission plates 5, when the rotating rod 3 drives the two groups of sliding columns 4 to rotate, they will slide left and right in the sliding grooves of the two groups of transmission plates 5 at the same time, and apply tension to the two groups of transmission plates 5, so that the two groups of transmission plates 5 are close to each other.

[0034] In this embodiment, two groups of fixed plates 6 are provided, and both groups of fixed plates 6 are provided in a rectangular shape. Because the two groups of fixed plates 6 are fixedly connected to the two groups of transmission plates 5 respectively, when the two groups of transmission plates 5 are close to each other, the two groups of fixed plates 6 will be driven to move close to each other. When the two groups of fixed plates 6 are close to each other and fit tightly with the guide tube 14, the chain 11 can be started to drive the fixed plate 6 to move to the left and pull the guide tube 14.

[0035] In this embodiment, a circular groove matching the size of the first inner mold 7 is opened on the side of the installation box 1, and six groups of mounting holes matching the screws 8 are opened on the side of the installation box 1 around the circular groove. By setting the circular groove and mounting holes on the side of the installation box 1, the first inner mold 7 can be first embedded into the circular groove on the side of the installation box 1, and then the screws 8 can be turned so that the screws 8 pass through the side of the first inner mold 7 and enter the mounting holes on the side of the installation box 1, thereby achieving the purpose of fixing the first inner mold 7 to the side of the installation box 1.

[0036] Example 2

[0037] On the basis of Example 1, a preferred embodiment of the utility model provided by the utility model for cold drawing of an integral solid inner die for an inclined material guide tube for petroleum is as follows Figures 1 to 5As shown: a mounting plate 9 is attached to the bottom of the mounting box 1, bolts 10 penetrate the surface of the mounting plate 9, a chain 11 is fixedly connected to the bottom of the mounting plate 9, a base 12 is fixedly connected to the bottom of the chain 11, a mold groove 13 is fixedly connected to the top of the base 12, a material guide tube 14 penetrates the side of the mold groove 13, and a second inner mold 15 is attached to the inner wall of the material guide tube 14.

[0038] In this embodiment, a mounting groove matching the size of the mounting box 1 is provided on the top of the mounting plate 9, and the mounting box 1 is embedded in the mounting groove of the mounting plate 9. By setting the mounting groove on the top of the mounting plate 9, the mounting box 1 can be first embedded in the rectangular groove on the top of the mounting plate 9, so that the circular hole on the surface of the mounting box 1 coincides with the circular hole on the surface of the mounting plate 9, thereby achieving the purpose of positioning.

[0039] In this embodiment, three groups of circular holes matching the sizes of the bolts 10 are provided on the surfaces and backs of the mounting plate 9 and the mounting box 1, and three groups of bolts 10 are arranged. Because three groups of circular holes matching the sizes of the bolts 10 are provided on the surfaces and backs of the mounting plate 9 and the mounting box 1, the bolts 10 can be first passed through the surfaces of the mounting plate 9 and the mounting box 1, and then the bolts 10 can be tightened, so as to achieve the purpose of fixing the mounting box 1 inside the mounting plate 9, and further achieve the purpose of fixing the pulling structure at the top of the mounting plate 9 to the top of the chain 11.

[0040] The working principle and use process of the utility model are as follows: first, the second inner mold 15 is embedded into the interior of the guide tube 14, and then the installation box 1 is embedded into the installation groove on the top of the installation plate 9, so that the circular hole on the surface of the installation box 1 coincides with the circular hole on the surface of the installation plate 9, and then the bolt 10 is screwed to fix the installation box 1 inside the installation plate 9, thereby fixing the pulling structure on the top of the installation plate 9 to the top of the chain 11, and then, the first inner mold 7 is embedded into the circular groove on the side of the installation box 1, and then the first inner mold 7 is fixed to the side of the installation box 1 by the screw 8. At this time, the chain 11 is started to embed the first inner mold 7 into the interior of the guide tube 14, and then the servo motor is controlled to drive the rotating shaft 2 to rotate clockwise. Because the rotating shaft 2 is fixedly connected to the rotating rod 3, when the rotating shaft 2 rotates, it will drive the rotating rod 3 to rotate clockwise together. Since the two sets of sliding columns 4 are both connected to the rotating The rod 3 is fixedly connected, and the two sets of sliding columns 4 are respectively embedded in the sliding grooves of the transmission plate 5, so when the rotating rod 3 rotates, it will drive the two sets of sliding columns 4 to slide left and right in the sliding grooves of the two sets of transmission plates 5, and apply tension to the two sets of transmission plates 5, so that the two sets of transmission plates 5 are close to each other. Because the two sets of fixed plates 6 are respectively fixedly connected to the two sets of transmission plates 5, when the two sets of transmission plates 5 are close to each other, the two sets of fixed plates 6 are driven to move close to each other. When the two sets of fixed plates 6 are close to each other until they are tightly fitted with the guide tube 14, the chain 11 can be started to drive the fixed plate 6 to move left, and pull the guide tube 14 to make the guide tube 14 separate from the second inner mold 15. Because the first inner mold 7 is always inside the guide tube 14, the guide tube 14 can be prevented from being deformed due to the extrusion force of the fixed plate 6, thereby achieving the purpose of reducing the incidence of defective products.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
