[0003] In order to reduce the labor burden of the staff, the existing cold drawing machine will be equipped with a blanking device to assist in blanking, but the existing blanking device requires manual control of the blanking track to extend under the stretched steel pipe, which is not convenient enough. Therefore, the technicians in this field provide a convenient blanking cold drawing machine for seamless steel pipe production to solve the problems raised in the above background technology. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is designed with a storage groove, and the guide plate can be stored in the storage groove, so that when the clamping table is close to the die seat, it can be closely attached to the die seat, thereby reducing the distance that the steel pipe passes through the die seat, so as to facilitate the clamping of the steel pipe after passing through. At the same time, when the clamping table is away from the die seat, the guide plate automatically pops up to reduce manual operation.

[0013] 2.

[0021] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] See also Figures 1 to 3 In this embodiment, a convenient blanking cold drawing machine for seamless steel pipe production is provided, including a slide rail 1, a die seat 2 is fixedly installed at one end above the slide rail 1, a moving platform 3 is slidably connected to the slide rail 1, a clamping platform 5 is fixedly installed above the moving platform 3, and a guide mechanism 7 is installed on the clamping platform 5 and the die seat 2. The guide mechanism 7 includes a receiving groove 71 opened on the clamping platform 5 and the die seat 2, and a guide plate 73 is slidably connected inside the receiving groove 71. A collecting groove 6 is provided on one side of the slide rail 1.

[0023] When in use, the guide plate 73 can be stored in the storage groove 71, so that when the clamping platform 5 is close to the die seat 2, it can be tightly attached to the die seat 2, thereby reducing the distance that the steel pipe passes through the die seat 2, thereby facilitating the clamping of the steel pipe after passing through. At the same time, when the clamping platform 5 is away from the die seat 2, the guide plate 73 pops out automatically to reduce manual operation.

[0024] In further embodiments, see Figure 1 A driving mechanism 4 is installed between the slide rails 1 and below the moving platform 3. The driving mechanism 4 includes a motor and a screw. The motor drives the screw to rotate, and the screw passes through the bottom of the moving platform 3 and is threadedly connected to the moving platform 3, so that the moving platform 3 can be pushed to move when the screw rotates.

[0025] In further embodiments, see Figure 2 The two ends of the receiving groove 71 are open and inclined, and the end of the receiving groove 71 with a lower horizontal height is close to the collecting groove 6. A fixing plate 72 is fixedly connected inside the receiving groove 71, and the fixing plate 72 is slidably connected to the guide plate 73. A spring 74 is arranged between the guide plate 73 and the fixing plate 72. When the die holder 2 and the clamping platform 5 are close to each other, the guide plate 73 can be squeezed and stored inside the receiving groove 71, and when the die holder 2 and the clamping platform 5 are far away from each other, the guide plate 73 can be ejected by the spring 74 to form a guide rail.

[0026] In further embodiments, see Figure 2The guide plate 73 is parallel to the receiving groove 71, and the length of the guide plate 73 is greater than the length of the receiving groove 71. This increases the displacement distance of the steel pipe sliding.

[0027] In further embodiments, see Figure 3 The receiving groove 71 on the die holder 2 is fixedly connected with a limit plate 77, and the guide plate 73 on the die holder 2 is vertically slidably connected with a friction block 75. One end of the friction block 75 is fixedly connected with a connecting rod 76. One end of the connecting rod 76 is bent downward, and the lower end of the connecting rod 76 is lower than the horizontal height of the limit plate 77. After the guide plate 73 is ejected by the spring 74, the lower end of the connecting rod 76 is moved away from under the limit plate 77, so that the connecting rod 76 can rise. At the same time, an elastic component is arranged under the friction block 75, so that the friction block 75 can be ejected after losing the restriction, thereby protruding the guide plate 73, increasing the friction between the guide plate 73 and the steel pipe, so that the friction of the guide plate 73 on one side of the die holder 2 is greater than the friction of the clamping seat 5 on the steel pipe.

[0028] In further embodiments, see Figure 2 The clamping platform 5 is slidably connected to a clamping plate 51, which is provided with a socket. One end of the clamping plate 51 is located inside the socket. A lifting mechanism is installed between the clamping plate 51 and the clamping platform 5. The lifting mechanism causes the clamping plate 51 to descend, and the clamping plate 51 descends to clamp the steel pipe inserted into the socket.

[0029] In further embodiments, see Figure 1 A guide rod 61 is installed on one side of the collecting tank 6, one end of the guide rod 61 is raised toward the guide plate 73, and a plurality of deceleration blocks are installed on the guide rod 61. The steel pipes sliding down from the guide plate 73 are guided by the guide rod 61 to fall into the collecting tank 6, and the deceleration blocks reduce the falling speed of the steel pipes to reduce the damage caused by the impact. The elastic bottom plate is provided inside the collecting tank 6 to make it fall as the number of steel pipes increases, thereby reducing the impact damage when the steel pipes fall.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
