Abstract

The utility model discloses a galvanized tension leveler, which comprises a machine frame and a roller frame of a supporting roller. The roller frame of the supporting roller is disposed on the machine frame. The roller frame of the supporting roller is set to three rows parallel to each other in the transverse direction and each three roller frames of the supporting rollers is set as a group in the longitudinal direction. The roller frame of the supporting roller located in the middle of each group is lower than edge roller frames of the supporting rollers located on both sides of the middle roller frame of the supporting roller. The middle roller frame of the supporting roller and the edge miller frames of the supporting roller are disposed in an intersect mode. The galvanized tension leveler is capable of eliminating the scratch on the surface of a plate strip, and quality of the plate strip is improved.

Description

Zinc-plated straightening machine

Technical field

The utility model relates to a kind of zinc-plated straightening machine.

Background technology

At present, in the zinc-plated field of strip, generally use zinc-plated straightening machine that strip is carried out stretch-bending straightening and handle, to eliminate the unflatness of zinc-plated strip.Strip is being carried out in the process of stretch-bending straightening, what contact with strip is working roll, and working roll is delivered to intermediate calender rolls with suffered power, and intermediate calender rolls is in the backing roll transmission to both sides.

Illustrated in figures 1 and 2 is present a kind of zinc-plated straightening machine roller box structural representation partly; Comprise frame 1 ' and backing roll roller frame 5 '; Backing roll roller frame 5 ' is located on the frame 1 '; Frame 1 ' goes up through bearing working roll 2 ' and intermediate calender rolls 3 ' is installed, and on the backing roll roller frame 5 ' backing roll 4 ' is installed.Backing roll 4 ' is cells arranged in matrix, is three row's multiple row structures, each arrange backing roll parallel to each other, etc. high the setting, each row also laterally arranges and has whenever listed three backing rolls 4 '.Intermediate calender rolls 3 ' is located at backing roll 4 ' top and is contacted with three backing rolls, the 4 ' line that lists together, and working roll 2 ' is located at intermediate calender rolls 3 ' top and is contacted with intermediate calender rolls 3 ' line.

But, in actual production, backing roll 4 ' per three one row on the present whole roller box of this zinc-plated straightening machine, be spaced, making has one section clear band 6 ' between every row.Though working roll 2 ' is delivered to backing roll 4 ' with intermediate calender rolls 3 ' with most of power in the process of straightening, finally is delivered on the frame 1 '.Working roll 2 ' can clear band 6 ' produce local bending with intermediate calender rolls 3 ' in the stretch-bending straightening process; And working roll 2 ' and intermediate calender rolls 3 ' axially are being free play; Will certainly produce amount of deflection, thereby produce axial force, finally make working roll 2 ' and intermediate calender rolls 3 ' produce cut with two groups of backing rolls, 4 ' engagement edge place; Finally being reflected on the strip is exactly long striped, influences the quality of strip.

The utility model content

The purpose of the utility model is in order to overcome deficiency of the prior art, a kind of zinc-plated straightening machine of in the stretch-bending straightening process, eliminating the strip surface scratch, improving the strip quality to be provided.

For realizing above purpose, the utility model is realized through following technical scheme:

A kind of zinc-plated straightening machine; Comprise frame and backing roll roller frame; Said backing roll roller is set up on the said frame; Said backing roll roller frame is three rows parallel to each other at horizontally set, and vertically per three backing roll roller framves are one group, and lateral margin backing roll roller frame and intermediate support roller roller frame and lateral margin backing roll roller frame that the intermediate support roller roller frame in the middle of being positioned in every group is lower than its both sides laterally are being crisscross arranged.

Preferably, in every group of said backing roll roller frame, height such as two said lateral margin backing roll roller framves and its are centered close on the vertical line of same row's lateral margin backing roll roller frame.

Preferably, the center of the roller of intermediate support described in every group roller frame equates to the distance of four said lateral margin backing roll roller framves of two adjacent groups.

The zinc-plated straightening machine of the utility model is through being divided into one group with vertical per three backing roll roller framves; Lateral margin backing roll roller frame and intermediate support roller roller frame that intermediate support roller roller frame in the middle of being positioned in every group is lower than its both sides laterally are being crisscross arranged with lateral margin backing roll roller frame, can eliminate the quality of strip surface scratch, raising strip.

Description of drawings

Fig. 1 is the part-structure sketch map of existing a kind of zinc-plated straightening machine.

Fig. 2 is the structural representation of the roller frame of zinc-plated straightening machine shown in Figure 1.

Fig. 3 is the part-structure sketch map of the zinc-plated straightening machine of the utility model.

Fig. 4 is the structural representation of the roller frame of zinc-plated straightening machine shown in Figure 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is carried out detailed description:

Like Fig. 3 and shown in Figure 4: zinc-plated straightening machine, comprise frame 1 and backing roll roller frame 2, backing roll roller frame 2 is installed on the frame 1.Horizontal two adjacent backing roll roller framves 2 are fixed backing rolls 5; Backing roll 5 tops are provided with the intermediate calender rolls 4 that contacts with backing roll 5 lines; Intermediate calender rolls 4 tops are provided with the working roll 3 that contacts with intermediate calender rolls 4 lines, and intermediate calender rolls 4 all is fixed on the frame 1 through bearing 6 with working roll 3.

Backing roll roller frame 2 is three rows parallel to each other at horizontally set; Vertically per three backing roll roller framves 2 are one group; Lateral margin backing roll roller frame 21 and intermediate support roller roller frame 22 that intermediate support roller roller frame 22 in the middle of being positioned in every group is lower than its both sides laterally are being crisscross arranged with lateral margin backing roll roller frame 21; That is, the floor projection of intermediate support roller roller frame in every group 22 and lateral margin backing roll roller frame 21 constitutes a triangle.Like this, can avoid every group of backing roll roller frame vertically to be provided with and cause producing between the two adjacent groups backing roll 5 clear band point-blank, reduce the cut on the strip; Can eliminate the cut on the strip through adjustment backing roll 5 in horizontal length.

In every group of backing roll roller frame 2, height such as two lateral margin backing roll roller framves 21 and its are centered close on the vertical line of same row's lateral margin backing roll roller frame 21.Helping backing roll 5 like this, more provides enough support forces to support intermediate calender rolls 4.

The preferably, the center of intermediate support roller roller frame 22 equates to the distance of four lateral margin backing rolls of two adjacent groups roller frame 21 in each group.Bearing capacity on each backing roll 5 of reasonable distribution so more.

The zinc-plated straightening machine of the utility model is through being divided into one group with vertical per three backing roll roller framves 2; Lateral margin backing roll roller frame 21 and intermediate support roller roller frame 22 that intermediate support roller roller frame 22 in the middle of being positioned in every group is lower than its both sides laterally are being crisscross arranged with lateral margin backing roll roller frame 21, can eliminate the quality of strip surface scratch, raising strip.

Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
