Description

Technical Field

[0001] The invention relates to the technical field of brass strip processing, in particular to a brass strip extrusion gap adjustable device. Background Art

[0002] Brass strips are used in industrial machinery parts, electrical products, decorative materials and handicraft materials because of their good plasticity, high strength and excellent appearance. Due to their wide application, the brass strips for different purposes require different thicknesses, so it is necessary to extrude the brass strips to change their thickness.

[0003] The publication number is CN216574871U. A brass strip processing and extrusion device solves the problem that the existing brass strip processing and extrusion device is not convenient for adjusting the processing thickness of the brass strip during the production process, and cannot clean the dust on the surface of the brass strip, which affects the quality after extrusion, thereby reducing the practicality of the extrusion device;

[0004] However, in this application, the driving roller actually extrude the brass strip in cooperation with the extrusion rod, and the two do not actually rotate relative to each other at the same time. When the extrusion gap becomes larger, the driving roller and the extrusion rod will become out of sync. Similarly, the driving roller and the extrusion roller have only one rotating end. When adjusting the extrusion gap, the driving roller and the extrusion rod may rotate out of sync, thereby damaging the surface of the brass strip. Summary of the invention

[0005] In view of this, the object of the present invention is to provide a brass strip extrusion gap adjustable device to solve the above-mentioned problem.

[0006] Based on the above purpose, the present invention provides a brass strip extrusion gap adjustable device, comprising:

[0007] A vertical support is set on the ground, and slide grooves are symmetrically arranged on both sides of the vertical support;

[0008] A movable pressing roller, the two axial ends of which are rotatably connected to the two sliding blocks respectively;

[0014] As an optional implementation, the upper end of each threaded rod is fixedly connected to a pulley, and a transmission belt is transmission-connected between the two pulleys.

[0015] As an optional embodiment, the lubrication mechanism includes an oil storage tank fixedly connected to the top of the vertical bracket, two oil passages are symmetrically arranged on the inner side of the vertical bracket, a first oil outlet and a second oil outlet are symmetrically arranged at the upper and lower ends of the oil passage, an oil seepage pipe is rotatably connected between the two first oil outlets and between the two second oil outlets, and an oiling sleeve is fixedly connected to the outside of each oil seepage pipe.

[0032] like Figure 1-Figure 5 As shown, a brass strip extrusion gap adjustable device comprises:

[0033] A vertical support 1 is set on the ground, and slide grooves 2 are symmetrically arranged on both sides of the vertical support 1;

[0034] The movable pressing roller 3 has two axial ends respectively connected to the two sliding blocks for rotation;

[0035] There are two threaded rods 4, which are respectively threadedly connected to the two ends of the top of the vertical bracket 1, and the bottom of each threaded rod 4 is rotatably connected to a slider 5, and the two sliders are respectively slidably connected in the two slide grooves 2, and each threaded rod 4 is fixedly connected to a crank 6;

[0036] A fixed pressure roller 7 is threadedly connected to the bottom of the vertical bracket 1, one end of the fixed pressure roller 7 is fixedly connected to a transmission shaft 8, and the transmission shaft 8 passes through the vertical bracket 1 and is transmission-connected to a motor;

[0037] A transmission mechanism 9, which is transmission-connected between the fixed pressure roller 7 and the movable pressure roller 3;

[0038] The lubrication mechanism 10 is disposed in the vertical support 1 and abuts between the movable pressure roller 3 and the fixed pressure roller 7 .

[0039] In this embodiment, the copper strip to be processed is placed between the fixed pressure roller 7 and the movable pressure roller 3, and the transmission mechanism 9 is driven by a motor (not shown in the figure) to rotate the fixed pressure roller 7 and the movable pressure roller 3 to rotate in opposite directions to process the copper strip. During this process, the slider 5 is moved up and down by rotating the threaded rod 4, driving the height of the movable roller to change, thereby changing the extrusion gap. During the extrusion process, the lubrication mechanism 10 will continuously lubricate the movable pressure roller 3 and the fixed pressure roller 7 to improve the quality of the processed copper strip.

[0040] As an optional implementation, Figure 3 As shown, the transmission mechanism 9 includes a first transmission gear 11 fixedly connected to one side of the fixed pressure roller 7, a second transmission gear 12 is rotatably connected to one side of the vertical bracket 1, a first connecting rod 13 is rotatably connected to one side of the second transmission gear 12, a second connecting rod 14 is hinged at the end of the first connecting rod 13, a third transmission gear 15 is rotatably connected to the hinge point between the second connecting rod 14 and the first connecting rod 13, a fourth transmission gear 16 is transmission-connected to the end of the second connecting rod 14, the fourth transmission gear 16 is rotatably connected to the sliding block, the first transmission gear 11 is meshed with the second transmission gear 12, and the second transmission gear 12 is meshed with the third transmission gear 15, and the third transmission gear 15 is also meshed with the fourth transmission gear 16;

[0041] In this way, during the change of the height of the movable pressure roller 3, the first transmission gear 11 can also transmit power to the fourth transmission gear 16 through the movement of the first connecting rod 13 and the second connecting rod 14, so that the movable pressure roller 3 keeps rotating.

[0042] As an optional implementation, Figure 2 As shown, a pulley 17 is fixedly connected to the upper end of each threaded rod 4 , and a transmission belt 18 is transmission-connected between the two pulleys 17 .

[0043] As an optional implementation, Figure 4 As shown, the lubrication mechanism 10 includes an oil storage tank 19 fixedly connected to the top of the vertical bracket 1, two oil passages 20 are symmetrically arranged on the inner side of the vertical bracket 1, and a first oil outlet 21 and a second oil outlet 22 are symmetrically arranged at the upper and lower ends of the oil passage 20, and an oil seepage pipe 23 is rotatably connected between the two first oil outlets 21 and between the two second oil outlets 22, and an oiling sleeve 24 is fixedly connected to the outside of each oil seepage pipe 23;

[0044] In this way, liquid lubricating oil is stored in the oil storage tank 19 , and the lubricating oil flows from the oil passage 20 to the oil seepage pipe 23 by natural gravity, and the lubricating oil seeps out from the oil seepage pipe 23 to the oiling sleeve 24 .

[0045] As an optional implementation, Figure 4 As shown, the oil storage tank 19 is provided with a refueling port 25, and an upper cover 26 is threadedly connected to the refueling port 25;

[0046] In this way, refueling of the fuel filler port 25 is achieved.

[0047] As an optional implementation, Figure 5As shown, the oil seepage pipe 23 is hollow, communicates with the oil passage 20, and is provided with fine pores;

[0048] In this way, the small gap on the oil seepage pipe 23 can allow the lubricating oil to slowly flow out from the deep part of the oil seepage pipe 23, thereby preventing the oil from seeping out too quickly.

[0049] As an optional implementation, the oiling sleeve 24 is made of sponge;

[0050] In this way, the oiling sleeve 24 is used to store lubricating oil, and after the oiling sleeve 24 is squeezed, the lubricating oil will be squeezed out.

[0051] As an optional embodiment, the oiling sleeve 24 at the upper end conflicts with the movable pressure roller 3, and the oiling sleeve 24 at the lower end conflicts with the fixed pressure roller 7;

[0052] In this way, after being abutted by the fixed pressure roller 7 and the movable pressure roller 3, the oiling sleeve 24 will evenly apply the lubricating oil inside to the surfaces of the fixed pressure roller 7 and the movable pressure roller 3, which is beneficial to the quality of the copper strip processing surface.

[0053] As an optional implementation, Figure 2 As shown, the side of the stand rotatably connected to the second transmission gear 12 is fixedly connected to a shield 27;

[0054] This is used to protect the safety of the staff.
