Description

Technical Field

[0001] The utility model belongs to the technical field of steel rolling production equipment and relates to a vertical looper outlet guide device. Background Art

[0002] The vertical looper is one of the necessary supporting equipment for the rolling mill in the modern high-speed wire rod rolling process. It is used to maintain an appropriate amount of looping between adjacent rolling mill frames, so as to achieve tension-free rolling of wire rods. The appropriate amount of looping can prevent the rolled pieces between the rolling mills from being pulled or piled up. During the rolling process, when the rolled pieces between the adjacent rolling mill frames are subjected to tension, the looper's looping amount is reduced, thereby playing a buffering role for the rolled pieces between the frames, thereby overcoming the tension formed in the rolled pieces that affects the quality of the rolled pieces themselves, and even causing necking and fracture due to excessive tension; and when there is a risk of excessive pile-up of rolled pieces between the frames, the looper's looping amount between the frames is increased to absorb the excessive rolled pieces, thereby avoiding pile-up of steel and eliminating safety hazards.

[0003] In order to reduce the potential safety hazards in the production process, guide grooves or guide guards are often placed at the entrance and exit of the rolling equipment to allow the rolled pieces to enter the subsequent rolling equipment accurately. The traditional vertical looper outlet is often equipped with a fixed guide groove. After a period of use, due to the wear between the rolled pieces and the guide groove, the bottom height of the guide groove is reduced, and it can no longer meet the original technical regulations and needs to be replaced. The replacement of the guide groove is not only costly, but also complicated to operate, which affects production. Therefore, it is necessary to optimize the vertical looper outlet guide groove to make it easy to replace while reducing the number of replacements and saving production costs. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the problem of frequent wear and replacement of vertical looper guide grooves, and to provide a vertical looper outlet guide device, which adopts a detachable roller mechanism instead of a fixed guide groove to reduce production costs.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A vertical looper outlet guide device comprises a base and two roller mechanisms detachably arranged up and down on the base; the base is detachably connected to the looper frame by bolts; a steel rolling channel is provided in the middle of the base, two guide guard plates arranged up and down are provided at the inlet end of the steel rolling channel, two roller mechanisms are symmetrically arranged at the outlet end of the steel rolling channel, and lateral baffles are provided on the left and right sides of the outlet end of the steel rolling channel.

[0007] Furthermore, the roller mechanism includes a roller, a rotating shaft, and a bracket; the roller is rotatably arranged on the rotating shaft, and the rotating shaft is fixed on the bracket. The bracket is provided with vertically arranged strip holes, and is connected to the base through the strip holes and bolts, and the installation height of the bracket is adjusted through the strip holes.

[0008] Furthermore, a shaft shoulder for positioning the roller is provided at one end of the rotating shaft, and the other end of the rotating shaft is fixed to the bracket via a locking nut; the rotating shaft and the roller are connected via a rolling bearing.

[0009] Furthermore, the guide guard plate is fixedly connected to the bracket.

[0010] Furthermore, the lateral baffle is welded to the base.

[0011] Furthermore, the base is provided with a strip hole, and is connected to the looper frame through the strip hole and the bolt, and the installation height of the base is adjusted through the strip hole.

[0012] The beneficial effects of the utility model are:

[0013] 1) The utility model adopts a detachable roller mechanism instead of a fixed guide groove. When the roller mechanism is worn out after long-term use, the roller spacing is accurately positioned by adjusting the roller mechanism, thereby solving the problem of setting a fixed guide groove at the outlet of the traditional loop and being difficult to replace after long-term use. The utility model has a simple structure and is easy to replace, saving the cost of replacing the outlet guide device.

[0014] 2) The utility model adopts an adjustable roller mechanism that can cooperate with the loop body to adapt to the passage of materials of various sizes, and improves the safety of materials passing through the loop during the rolling process through the guide guard plate and the side baffle.
