[0002] In order to better protect the wall surface during the construction of the wall corner, the wall corner guards are used. According to the use position, the corner guards are divided into: positive corner guards (positive corners are installed in the protruding wall corners, most of which are large-hole profiles with a cross-section angle greater than 90 degrees), negative corner guards (negative corners are installed in the concave wall corners, most of which are small round holes, and the cross-section angle of the profile is less than 90 degrees), bendable corner guards, T-shaped corner guards, which have a wide variety of types, are quick to operate and convenient to construct, and can strengthen the strength of the wall corners, and have a wide range of practicality.

[0003] In the prior art, corner guards are usually produced in a relatively long length and are then cut at equal distances according to the use environment. However, the angles of the corner guards are different depending on the use environment, so different positioning molds need to be replaced when cutting the corner guards, which affects the cutting efficiency of the corner guards. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a pre-pressing positioning mechanism and a cutting machine for producing corner protectors, so as to solve the technical problems mentioned in the above background technology.

[0007] Furthermore, the positioning assembly includes a splint, a base plate and an auxiliary rod. Two splints are symmetrically arranged at the bottom center of the pressure plate. The two splints are connected to the pressure plate through a hinge.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 3 The utility model discloses a pre-pressing positioning mechanism, which includes a base 1, a support frame 2 is fixedly connected to the top of the base 1, a hydraulic press 3 is fixedly connected to the top of the support frame 2, an output shaft of the hydraulic press 3 passes through the support frame 2 and is connected to a pressing plate 4, a positioning component 5 for pressing the corner guard is connected to the bottom of the pressing plate 4, and an anti-slip pad 6 is fixedly connected to the top of the base 1 directly below the positioning component 5.

[0026] In this embodiment, the corner guard is placed on the anti-slip pad 6, and then the hydraulic press 3 is started to push the pressure plate 4 downward. During the downward movement of the pressure plate 4, the positioning assembly 5 at the bottom of the pressure plate 4 will gradually approach the corner guard and clamp the corner guard. After the positioning of the corner guard is completed, the corner guard is cut by the cutting machine body 11, and then the above steps are repeated in sequence to achieve continuous cutting of the corner guard, thereby improving the cutting efficiency of the corner guard.

[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, the positioning assembly 5 includes a clamping plate 51, a base plate 52 and an auxiliary rod 53. Two clamping plates 51 are symmetrically arranged at the bottom center of the pressure plate 4. The two clamping plates 51 are connected to the pressure plate 4 through hinges. The side of the clamping plate 51 away from the base plate 52 is rotatably connected to the base plate 52. One side of the base plate 52 is connected to the pressure plate 4 through an auxiliary rod 53.

[0028] In this embodiment, when the inclination angle of the corner guard becomes larger, the pressure plate 4 presses down with the positioning assembly 5 to approach the corner guard, and the clamping plate 51 in the positioning assembly 5 will first contact the corner guard, and then the clamping plate 51 will slide under the influence of the inclined surface of the corner guard, so that the two clamping plates 51 are opened, so that the clamping angle of the clamping plate 51 can be automatically adjusted according to the angle of the corner guard, so that the positioning assembly 5 can be used for a variety of corner guards, thereby improving the practicality of the pre-compression positioning mechanism.

[0029] Because the clamping plate 51 is stretched out by the corner bead, the clamping plate 51 cannot effectively support the pressing plate 4. Therefore, after the clamping plate 51 is attached to the corner bead, the output shaft of the hydraulic press 3 is still extended, so that the pressing plate 4 continues to press down and crushes the corner bead. Therefore, a bottom plate 52 is rotatably connected to one side of the clamping plate 51, and an anti-skid pad 6 is provided on the top of the base 1. After the clamping plate 51 contacts the anti-skid pad 6, a large friction force is generated by the contact between the bottom plate 52 and the anti-skid pad 6 to prevent the clamping plate 51 from sliding along the horizontal plane of the base 1, so that the clamping plate 51 can provide support for the pressing plate 4 and prevent the pressing plate 4 from crushing the corner bead.

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, the length of the auxiliary rod 53 is the same as the width of the clamping plate 51 , and the auxiliary rod 53 is arranged parallel to the clamping plate 51 .

[0031] In this embodiment, because the clamping plate 51 will automatically adjust the opening angle according to the inclination of the corner bead, the bottom plate 52 connected to the clamping plate 51 will rotate with the clamping plate 51, resulting in the bottom plate 52 not being able to completely fit with the anti-skid pad 6, thereby reducing the friction between the bottom plate 52 and the anti-skid pad 6, affecting the support of the clamping plate 51 to the pressure plate 4. Therefore, an auxiliary rod 53 is provided between the bottom plate 52 and the pressure plate 4, and the length of the auxiliary rod 53 is the same as the width of the clamping plate 51. The auxiliary rod 53 is kept parallel to the clamping plate 51, and can provide support to the bottom plate 52 when the clamping plate 51 rotates, so as to ensure that the bottom plate 52 and the anti-skid pad 6 remain level, so that the clamping plate 51 supports the pressure plate 4 more stably.

[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, the bottom of the bottom plate 52 is provided with an anti-skid texture for increasing friction.

[0033] In this embodiment, by providing an anti-skid texture on the bottom of the bottom plate 52 , the friction force generated after the bottom plate 52 contacts the anti-skid pad 6 can be further increased, thereby greatly improving the supporting effect of the clamping plate 51 on the pressure plate 4 .

[0034] In a further preferred embodiment of the present invention, Figure 3As shown, the top of the pressure plate 4 is fixedly connected with a sleeve 7, a piston 8 is slidably connected inside the sleeve 7, a supporting spring is connected between the bottom of the piston 8 and the sleeve 7, the top of the piston 8 is fixedly connected to the output shaft of the hydraulic press 3, and a pressure touch switch 9 is fixedly connected to the inner bottom wall of the sleeve 7.

[0035] In this embodiment, when the positioning component 5 touches the bottom, the hydraulic press 3 needs to be manually shut down to prevent the hydraulic press 3 from continuing to push the pressure plate 4 downward and crushing the positioning component 5. This operation method requires the operator to always keep an eye on the operation of the hydraulic press 3, which increases the burden on the workers.

[0036] Therefore, a sleeve 7 is provided on the top of the pressure plate 4, and a piston 8 is connected to the sleeve 7 through a supporting spring. The top of the piston 8 is connected to the output shaft of the hydraulic press 3. At this time, after the positioning assembly 5 touches the bottom, the hydraulic press 3 continues to run and the output shaft pushes the piston 8 downward in the sleeve 7 until the piston 8 contacts the pressure switch 9 and issues a command to shut down the hydraulic press 3, so that the hydraulic press 3 can stop automatically, thereby reducing the tasks of the workers and alleviating the burden on the workers.

[0037] In a further preferred embodiment of the present invention, Figure 2 As shown, two guide rails 10 are symmetrically arranged on the top of the pressure plate 4 with the hydraulic press 3 as the center, and the tops of the two guide rails 10 both extend upward and penetrate the support frame 2.

[0038] In this embodiment, a guide rail 10 is provided on the top of the pressing plate 4 to assist the movement of the pressing plate 4, thereby making the operation of the pressing plate 4 more stable and improving the positioning effect of the corner guard.

[0039] Reference Figure 1 The utility model discloses a cutting machine for producing corner guards, which includes a pre-pressing and positioning mechanism and a cutting machine body 11. The cutting machine body 11 is fixedly connected to one side of the base 1 and fits with one side of the support frame 2.

[0040] In this embodiment, by providing a cutting machine body 11 and cooperating with the pre-pressing positioning mechanism, the corner guard strips can be efficiently cut after the corner guard strips are positioned, which can effectively improve the production efficiency of the corner guard strips and make the cutting machine more practical.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
