Description

Technical Field

[0001] The utility model belongs to the technical field of metal rolling positioning, and specifically relates to a metal positioning rolling machine. Background Art

[0002] Metal rolling is one of the processes in the steel industry. In fact, it is the process of melting the raw metal ore and reducing it into billets and molds of a certain purity. These billets and molds after smelting and casting are made into the required shape or structural form through external forces such as rolling, forging or extrusion. This is the process of rolling.

[0004] However, in actual work, most of the rolled metals are of different sizes, and workers need to frequently turn the threaded rod to adjust the position of the sliders at both ends, which increases the number of operation steps for workers and reduces work efficiency. At the same time, the positioning mechanism adjusts the position of the movable limit plate through the positioning hole, resulting in a limited adjustment range, making it impossible to tightly clamp the metal, so that the metal can move during the rolling process, which affects the rolling quality.

[0005] In view of this, the present utility model is proposed. Utility Model Content

The following embodiments are used to illustrate the utility model.

[0028] See also Figure 1-6A metal positioning calender comprises an operating table 1, a calendering assembly 8 is movably installed on the operating table 1, a cavity is opened in the operating table 1, a push block 4 is rotatably connected in the cavity, both sides of the push block 4 are abutted with transmission blocks 402, the transmission blocks 402 are movably installed in the cavity of the operating table 1, the push block 4 can rotate and push the two transmission blocks 402 to slide in the opposite direction, and the transmission blocks 402 are installed with clamping mechanisms 2 for clamping metal, and the clamping mechanism 2 is driven to move outward by the outward movement of the transmission block 402, so as to separate from the metal, release the restriction on the metal, and clamp the metal. The mechanism 2 includes a shell 205, which is arranged above the transmission block 402. A bidirectional threaded rod 202 is rotatably installed in the shell 205. The outer walls on both sides of the bidirectional threaded rod 202 are provided with external threads with opposite thread directions. The wall of the shell 205 is slidably connected with two clamps 201. Both clamps 201 are threadedly connected to the bidirectional threaded rod 202. By rotating the bidirectional threaded rod 202, the opposite thread directions at both ends drive the clamps 201 at both ends to move inward or outward at the same time, thereby adjusting the fine size of the metal clamping, making the clamps 201 fit closely to the metal surface, and improving the clamping effect.

[0029] It is worth noting that the calendering assembly 8 is composed of a bracket, a moving mechanism, an adjusting mechanism, a calendering mechanism, etc. The moving mechanism is used to drive the bracket to move horizontally on the operating table 1, and the adjusting mechanism and the calendering mechanism are used to control the calendering roller to press down and calender the metal. Among them, the structures of the calendering assembly 8, the bracket, the moving mechanism, the adjusting mechanism, the calendering mechanism, etc. are all prior arts, which have been disclosed in a non-ferrous metal calendering device (application number 202311661113.1) and will not be repeated here.

[0030] Specifically, the middle axis of the pushing block 4 is connected to the driving motor 401, and the driving motor 401 is fixedly installed in the cavity. Both ends of the pushing block 4 are raised semi-ellipses, and the arc surface abuts the transmission block 402. The driving motor 401 drives the pushing block 4 to rotate, thereby driving the device.

[0031] Specifically, fasteners 403 are clamped at both ends of the transmission block 402, and a return spring 404 is provided between the two fasteners 403. The two ends of the return spring 404 are fixedly connected to the two fasteners 403 respectively. The return spring 404 can pull the two transmission blocks 402 closer to each other. The return spring 404 uses its own elasticity to pull the transmission block 402 inward at the same time, and the transmission block 402 drives the shell 205 to move inward, so that the metal is quickly clamped and fixed, reducing the number of workers' operating steps and improving work efficiency. At the same time, the fastener 403 is clamped, so that the fastener 403 can be quickly installed and disassembled, thereby quickly installing and disassembling the return spring 404.

[0032] Specifically, a connecting shaft is fixedly installed at one end of the two-way threaded rod 202, and the connecting shaft is rotatably connected to the shell 205. A knob 203 is fixedly connected to the end of the connecting shaft. A baffle 204 is arranged in the middle of the two-way threaded rod 202, and the baffle 204 is fixedly connected to the shell 205. The two-way threaded rod 202 movably connects the baffle 204. The knob 203 is rotated manually to drive the two-way threaded rod 202. The baffle 204 in the middle of the two-way threaded rod 202 is used to limit the movable range of the splint 201, so as to avoid operating errors of workers, which will cause the splints 201 at both ends to always move inward, resulting in excessive extrusion and damage of the splint 201, thereby improving the service life of the device.

[0033] Specifically, one end of the pushing block 4 is axially connected to a connecting rod 301, and the other end of the connecting rod 301 is axially connected to a push plate 3. A second slide groove 6 is provided on the top of the operating table 1. The pushing block 4 is rotated to drive one end of the connecting rod 301 to move, and the other end of the connecting rod 301 drives the push plate 3 to move inward. The rolled metal is pushed out of the operating table 1 by the push plate 3, thereby completing the unloading while releasing the clamping of the metal, reducing the operating steps of the workers and improving work efficiency.

[0034] Specifically, a limit block 405 is fixedly connected to the middle part of the transmission block 402, a first slide groove 5 is provided on the top of the operating table 1, the limit block 405 is slidably connected to the first slide groove 5, and the upper end of the limit block 405 is fixedly connected to the shell 205. The movable range of the limit block 405 is limited by the first slide groove 5, thereby avoiding the shell 205 from being offset when the shell 205 is driven to move, thereby affecting the clamping effect.

[0035] Specifically, the push plate 3 is slidably connected to the second slide groove 6. The push plate 3 is in an I-shape as a whole. The groove in the middle of the push plate 3 is slidably connected to the second slide groove 6. The second slide groove 6 limits the range of movement of the push plate 3, so that the push plate 3 is pushed back and forth, thereby ensuring the continuity of unloading of the device.

[0036] Specifically, a plurality of legs 7 are fixedly connected to the bottom end of the operating platform 1 , and the legs 7 support the operating platform 1 , and the legs 7 support the ground surface of the operating platform 1 .

[0037] When in use, the return spring 404 uses its own elasticity to pull the transmission block 402 inward at the same time, and the transmission block 402 drives the clamping mechanism 2 to move inward, so that the metal is quickly clamped and fixed, reducing the number of operating steps for workers and improving work efficiency. The knob 203 is turned by manpower to drive the bidirectional threaded rod 202 to rotate, and the opposite thread directions at both ends drive the clamping plates 201 at both ends to move inward or outward at the same time, thereby adjusting the fine size of the metal clamping, making the clamping plates 201 fit the metal surface closely, and improving the clamping effect. The calendering operation is performed through the calendering mechanism inside the calendering assembly 8. When the calendering is completed, the driving motor 401 drives the pushing block 4 to rotate, and the transmission block 402 moves outward to drive the clamping mechanism 2 to move outward to separate from the metal and release the restriction on the metal. At the same time, the pushing block 4 rotates to drive one end of the connecting rod 301 to follow the movement, and the other end of the connecting rod 301 drives the push plate 3 to move inward, and the pushed plate 3 is used to push the rolled metal from the operating table 1, thereby completing the unloading while releasing the clamping and fixation of the metal, reducing the operating steps of the workers and improving work efficiency.
