Description

A sheet metal guiding and positioning device

technical field

The utility model relates to an auxiliary device for automatic stamping production, in particular to a device for positioning sheets during automatic stamping production.

Background technique

The stamping factory implements an automated production method. The sheet material enters the press mold through the feeding table. Before entering the press mold, it must be centered and positioned, so as to ensure that the position is the same every time, and the press mold will not be crushed due to inconsistent positions. . However, due to the beveled edges of some special-shaped sheets, the shapes of the sheets are inconsistent, and the quality of the sheets is asymmetrical. Under the action of gravity, the sheets cannot move forward on the belt, and they are easy to deviate and cannot enter the press mold in the center. , unable to go into production smoothly. The utility model with the notification number CN 2348952Y discloses a sheet metal positioning device for shearing machines and bending machines, which includes a front bracket, a rear bracket, a plurality of sliding brackets and a positioner arranged between the front and rear brackets, each sliding At least one locator is installed on the support, and the locator is fixed on one side of the sliding bracket by T-shaped bolts and fasteners. The locator is composed of a dolphin-shaped positioning body with a positioning surface, a sleeve, a box body, and a guide plate. It is easy to adjust the position of the positioner on the sliding bracket, and the operation is very convenient, and the positioning surface is small, which eliminates the error caused by the burr of the sheet material, making the positioning more accurate. But this utility model lacks the control to the deviation of special-shaped sheets, and it cannot be precisely positioned. The purpose of the utility model is to overcome the defect that the special-shaped sheet is easy to deviate and the positioning is not accurate in the prior art, and to provide a device for guiding and positioning the sheet, which can smoothly center the special-shaped sheet and achieve the purpose of smooth production.

Contents of the invention

The utility model provides a sheet material guiding and positioning device aiming at the problems in the prior art that the special-shaped sheet material is easy to deviate during the transmission process and cannot be centered smoothly.

The utility model mainly solves the above-mentioned technical problems through the following technical solutions: a sheet material guiding and positioning device, including a baffle plate and a bracket, and the middle of the baffle plate has a kink angle of 120 degrees to 165 degrees toward the bracket direction, according to the special shape of the sheet material Choose the number of folding angles according to the degree. When the slope of the special-shaped sheet material is seriously inclined, choose a large number of folding angles. When the slope of the special-shaped sheet material is slightly inclined, choose a small number of folding angles. The slider and the bracket are movably connected with the adjustment slider, the adjustment slider is provided with a fixing screw, and one side of the adjustment slider is welded and fixed with a U-shaped positioning card frame. When using the sheet material guiding and positioning device, the positioning card frame is clamped on the centering table in front of the press, the baffle is placed on the side of the feeding table, and then the bracket is adjusted according to the position where the sheet material passes, so that the bracket is relatively adjusted. The slider slides, slides the baffle to a suitable position on the conveying table, and then screws the fixing screw in and pushes it against the bracket, so that the position of the bracket is fixed, so that the position of the baffle is fixed, and there is no centered sheet or When the special-shaped sheet passes through the guide and positioning device, one side of the sheet is forward and one side is rearward, and the front side collides with the baffle surface. Under the reaction force of the baffle, the front side of the sheet is resisted. Slowly return to the center along the guide of the baffle, until after passing through the corner of the baffle, the sheet is smoothly centered and enters the press mold. The sheet material guiding and positioning device can smoothly center the sheet materials, especially the special-shaped sheet materials, and improve the product quality. The device has a simple structure and is easy to use.

As a preferred solution of the above solution, it is characterized in that balls or pulleys are installed between the bracket and the adjustment slider, so that the relative adjustment of the sliding bracket can be more flexible and the use is more convenient.

As a preferred solution of the above solution, it is characterized in that the support is a hollow tube, and the device is portable.

Therefore, the utility model has the characteristics of simple structure, convenient operation, improved product quality, and increased production efficiency.

Detailed ways

The technical scheme of the utility model is further specifically described below through the embodiments in conjunction with the accompanying drawings.

As shown in the accompanying drawing 1, a sheet material guiding and positioning device includes a baffle plate 1 and a bracket 2, and is characterized in that the middle of the baffle plate has a 160-degree knuckle in the direction of the bracket, and the bracket is fixedly connected in the middle of the baffle plate position, the bracket is provided with an adjustment slider 3, the bracket is movably connected with the adjustment slider, the adjustment slider is provided with a fixed screw 4, and one side of the adjustment slider is welded and fixed with a U-shaped positioning card frame 5.

As shown in accompanying drawing 2 and accompanying drawing 3, the positioning card frame of the guide positioning device of the sheet metal is clamped on the centering table 6 in front of the press, and the positioning card frame is connected to the adjusting slider, which also makes the adjusting slider The position of the baffle is fixed, and the baffle is placed on the side of the feeding table 7, and then the bracket is adjusted according to the position where the sheet material passes, so that the bracket slides relative to the adjusting slider, and slides to a suitable position on the feeding table with the baffle, and then Screw in the fixing screw and push it against the bracket, so that the position of the bracket is fixed, so that the position of the baffle is fixed. When there is no centered sheet or special-shaped sheet passing through the guiding and positioning device, one side of the sheet is front and one side is When the edge is close to the back, the front side collides with the baffle surface. Under the reaction force of the baffle, the front side of the sheet is resisted, and slowly returns to the center along the guide of the baffle until it passes through the corner of the baffle. The material enters the press mold smoothly. The device can make the sheet material be positioned smoothly, and especially plays a good guiding and centering effect on the special-shaped sheet material, so that the product quality is improved. The device has a simple structure and is easy to use.
