Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a plate shearing positioning device. Background Art

[0002] In the construction, decoration, light industry and other industries, shearing machines and other equipment are needed to cut plates. The core structure of the current shearing machine lies in two blades with a reasonable blade gap, including a moving upper blade and a fixed lower blade, which apply shear force to metal plates of various thicknesses to break and separate the plates according to the required size.

[0003] Generally, the plate is transported to the bottom of the blade for shearing by means of external force such as conveyor belts or manual pushing. However, thicker plates may deviate from the predetermined conveying path, causing the subsequent blade cut surface to be non-parallel to the previous blade cut surface, thus affecting the shearing quality.

[0004] In summary, we need to consider avoiding the problem of plate deviation and warping when shearing the plate, so that it can always maintain a predetermined position relationship and be transported forward for shearing; in view of this, we propose a plate shearing positioning device.

[0032] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-6 The utility model describes the above technical solution in detail through the following embodiments:

[0034] A plate shearing and positioning device comprises a conveyor belt 1 for conveying plates, and further comprises:

[0035] The shear positioning part includes a shear blade 7 installed on the mounting side frame 2, and a transmission roller 8 arranged on both sides of the shear blade 7. The transmission roller 8 is provided with two pressure positioning components on one side close to the plate to be sheared. The shear blade 7 of this embodiment is a group of shear blades, and its shearing action is an existing mature technology.

[0036] The pressing assembly comprises a pressing roller 4 for pressing the plate to prevent it from tilting. The pressing roller 4 is provided with two positioning snap rings 6. The positioning snap rings 6 are used to keep the conveying path of the plate to be sheared at the rear unchanged.

[0037] The plate shearing and positioning device of the present embodiment has the following working principle: the spacing between the positioning rings 6 on the two pressure rollers 4 is adjusted by the width of the plate, so that the plate is limited between the positioning rings 6, the pressure rollers 4 are adjusted to fit the surface of the plate, the conveyor belt 1 is conveyed forward, and the shearing blade 7 is sheared. Under the action of the pressure rollers 4 and the positioning rings 6, the plate cannot be tilted or shifted, and is always conveyed forward in the direction defined by the two positioning rings 6, which is conducive to obtaining a stable and front-to-back parallel knife edge section.

[0038] See also Figure 1 In the structure shown, in this embodiment, conveyor belts 1 are provided on both sides of the two driving rollers 8, and the highest point of the roller surface of the driving roller 8 is consistent with the belt surface height of the conveyor belt 1. The purpose is to continuously transport the sheared plates and the plates to be sheared forward by the conveyor belt 1. Here, the driving roller 8 can play a transition role, so that the force acts on the roller body, keeping the belt surface of the conveyor belt 1 always horizontal and without deformation. A driving motor 9 is installed on the mounting side frame 2, and the driving motor 9 is coaxially connected to the output shaft of the driving roller 8.

[0039] In this embodiment, the pressure roller 4 is arranged above the conveyor belt 1, so that the pressure roller 4 and the driving roller 8 are respectively located on the upper and lower sides of the plate, and the shearing position is shown in the figure. During shearing, the plate tends to press upward against the pressure roller 4. If the pressure roller 4 is not provided, it will cause warping. In this embodiment, two pressure rollers 4 are provided.

[0040] See also Figure 2-Figure 5 In the structure shown, both ends of the pressure roller 4 are provided with height adjustment units 5, and the height adjustment unit 5 includes a connecting block 51 with a rotating hole 512; the pressure roller 4 can rotate in the rotating hole 512 through the bearing 10, thereby reducing friction, so that the pressure roller 4 only plays the role of fitting the plate in height, avoiding hindering the forward conveyance of the plate.

[0041] In this embodiment, a vertical frame 3 is detachably mounted on the mounting side frame 2, and a lifting chamber 31 and a socket 301 are provided on the vertical frame 3; a sliding groove 511 for being inserted into the lifting chamber 31 is provided on the connecting block 51, and a threaded vertical rod 52 for passing through the socket 301 is installed on the connecting block 51, and a nut 53 is installed on the threaded vertical rod 52. The height of the connecting block 51 in the lifting chamber 31 can be controlled by adjusting the nut 53, which is suitable for plates of different thicknesses and has adjustability.

[0042] See also Figure 6 In the structure shown, a groove 401 is provided on the pressure roller 4, and a protrusion 61 that fits with the groove 401 is provided on the positioning snap ring 6. The positioning snap ring 6 is slidably installed on the pressure roller 4. The positioning snap ring 6 is provided with a groove 611 at the protrusion 61. A threaded hole is provided at the bottom of the groove 611. A fastening screw 11 is detachably installed at the threaded hole, and the spacing of the positioning snap ring 6 can be adjusted according to the width of the plate and then fixed.

If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "multiple" means more than two.
