Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of punching equipment, specifically to a tension adjustment mechanism and a punching equipment containing the mechanism. Background Technology
[0002] Blanking involves the relative movement of the punch and die, which, under the action of a press, causes the material to undergo shear deformation and separation along a specific contour. The process is divided into three stages: elastic deformation, plastic deformation, and fracture separation. In the blanking process of strip materials, the strip needs to be tensioned and flattened.
[0003] Currently, in the process of tensioning the material strip, it is usually necessary to use a feeding servo controller and a tension detection mechanism to detect and adjust in real time to maintain a constant tension in the material strip during the punching process. However, the equipment purchase and maintenance costs of such systems are relatively high, and their effect on improving the production efficiency of small enterprises is limited.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a tension adjustment mechanism and a punching device containing the mechanism. Utility Model Content
[0005] The purpose of this invention is to provide a tension adjustment mechanism and a punching device containing the mechanism, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a tension adjustment mechanism, comprising a base and a lifting assembly, wherein columns are symmetrically arranged at one top end of the base, and a top plate is fixed to the top of the columns; the lifting assembly is disposed on the outer side of the middle part of the top plate, and the lifting assembly includes a sliding sleeve, a mounting seat and a pressure roller; the sliding sleeve is slidably connected to the outer side of the middle part of the columns, and a mounting seat is fixed to the outer side of the sliding sleeve; and a pressure roller is rotatably connected to one side of the mounting seat.
[0007] Furthermore, the mounting base is L-shaped, and there are two mounting bases.
[0008] Furthermore, side plates are symmetrically arranged at both ends of the bottom of the top plate, and one end of the side plate is rotatably connected to a limit roller.
[0009] Furthermore, a guide roller is rotatably connected to the other end of the side plate, and the cross-section of the guide roller is I-shaped.
[0010] Furthermore, the top of the mounting base is provided with an adjustment component, which includes a screw, a counterweight, and a nut. The counterweight is sleeved on the outside of the screw, and a nut is provided on the top of the counterweight.
[0011] Furthermore, the nut is threadedly connected to the screw, and the screw is fixedly connected to the mounting base.
[0012] Furthermore, the counterweight is ring-shaped, and the inner diameter of the counterweight is smaller than the diameter of the nut.
[0013] A blanking device, wherein the blanking device is equipped with a tension adjustment mechanism as described above.
[0014] This utility model provides a tension adjusting mechanism and a punching device containing the mechanism, which has the following beneficial effects: 1. This utility model, through the setting of the lifting component, forms a V-shaped structure as the material strip passes sequentially through the upper part of the limiting roller, the bottom of the pressure roller, and the upper part of the guide roller. Therefore, when the feeding mechanism and the winding mechanism of the punching equipment stop working and are ready to punch the material strip, the pressure roller will move downward along the column under the action of gravity, automatically tightening and flattening the material strip between the winding mechanism and the feeding mechanism, improving the quality of subsequent punching. At the same time, no additional control and monitoring system is required, thereby saving maintenance costs and improving the production efficiency of enterprises. 2. By adjusting the settings of the components, when it is necessary to adjust the applied tension according to the material of the strip, simply put the counterweight of the specified weight on the screw and then lock it with the nut to change the pressure applied by the pressure roller, thereby meeting the usage requirements under different conditions and further improving the adaptability of the equipment.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0018] like Figure 1 and Figure 2As shown, a tension adjusting mechanism includes a base 1 and a lifting assembly 4. A column 2 is symmetrically arranged at one top end of the base 1, and a top plate 3 is fixed to the top of the column 2. The lifting assembly 4 is located on the outer side of the middle portion of the top plate 3, and includes a sliding sleeve 401, a mounting seat 402, and a pressure roller 403. The sliding sleeve 401 is slidably connected to the outer side of the middle portion of the column 2, and the mounting seat 402 is fixed to the outer side of the sliding sleeve 401. The pressure roller 403 is rotatably connected to one side of the mounting seat 402. The mounting seat 402 is L-shaped, and there are two mounting seats 402. The mounting seat 402 limits the pressure roller 403. At the bottom of the top plate 3, side plates 5 are symmetrically arranged at both ends. One end of the side plate 5 is rotatably connected to a limiting roller 6, and the other end of the side plate 5 is rotatably connected to a guide roller 7. The guide roller 7 has an I-shaped cross section. Since the material strip passes through the upper part of the limiting roller 6, the bottom of the pressure roller 403, and the upper part of the guide roller 7 in sequence, forming a V-shaped structure, when the feeding mechanism and the winding mechanism of the punching equipment stop working and are ready to punch the material strip, the pressure roller 403 will drive the sliding sleeve 401 in the mounting base 402 to move downward along the axial direction of the column 2 under the action of gravity, automatically tightening and flattening the material strip between the winding mechanism and the feeding mechanism.
[0019] like Figure 3 As shown, the top of the mounting base 402 is provided with an adjustment component 8, which includes a screw 801, a counterweight 802, and a nut 803. The counterweight 802 is sleeved on the outside of the screw 801, and the nut 803 is provided on the top of the counterweight 802. The nut 803 is threadedly connected to the screw 801, and the screw 801 is fixedly connected to the mounting base 402. The counterweight 802 is annular, and the inner diameter of the counterweight 802 is smaller than the diameter of the nut 803. By simply putting the counterweight 802 of a specified weight on the screw 801 and then locking it with the nut 803, the pressure applied by the pressure roller 403 can be changed, thereby meeting the usage requirements under different conditions.
[0020] A punching device is provided, which is equipped with the tension adjustment mechanism described above, so that no additional control and monitoring system is required during the tensioning of the strip, which helps to save maintenance costs and improve the production efficiency of enterprises.
[0021] In summary, when using this tension adjustment mechanism and the blanking equipment containing this mechanism, firstly according to... Figure 1 , Figure 2 and Figure 3The structure shown illustrates that during the conveying of the material strip, the material strip fed by the feeding mechanism at one end of the base 1 passes sequentially through the upper part of the limiting roller 6, the bottom of the pressure roller 403, and the upper part of the guide roller 7, forming a V-shaped structure. It is then wound up by the winding mechanism after passing through the punching mechanism. Next, the feeding and winding mechanisms of the punching equipment stop working, and the pressure roller 403, under the action of gravity, drives the sliding sleeve 401 in the mounting base 402 to move downward along the axial direction of the column 2, automatically tightening and flattening the material strip between the winding and feeding mechanisms. Then, the punching mechanism of the punching equipment punches the tensioned material strip, thereby improving the quality of subsequent punching. At the same time, no additional control and monitoring system is required, thus saving maintenance costs. Finally, when it is necessary to adjust the applied tension when processing material strips of different materials, simply put the counterweight block 802 of a specified weight on the screw 801 and lock it with the nut 803 to change the pressure applied by the pressure roller 403, thereby meeting the usage requirements under different conditions.
