Description

Technical Field

[0001] The utility model relates to the technical field of spiral steel pipe shearing, in particular to an anti-corrosion plastic-coated spiral steel pipe shearing and forming device. Background Art

[0002] The spiral steel pipe is a spiral seam steel pipe made of strip steel coils, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding. The spiral steel pipe feeds the strip steel into the welded pipe unit, and after multiple roller rolling, the strip steel gradually rolls up to form a round pipe blank with an open gap.

[0003] During the production and processing of spiral steel pipes, shearing equipment is used so that the spiral steel pipes can be sheared into specified specifications for later use. At present, before shearing, the spiral steel pipes are fixed with limit plates at both ends, and then the cutting end is sheared at the measured position after measurement with a ruler, thereby realizing the shearing of the spiral steel pipe. However, this method has the following shortcomings when used: the shearing equipment limits the two ends of the spiral steel pipe through the limit plates, and the limit plates are fixedly connected to the shearing equipment, which makes the shearing equipment only clamp one specification of spiral steel pipe. If a spiral steel pipe with a larger or smaller specification is encountered, the limit plates are difficult to fit with the wall of the spiral steel pipe, so that the stability of the spiral steel pipe after limiting cannot be guaranteed; and because the two ends of the spiral steel pipe are limited by the limit plates, the cutting end will generate pressure on the shearing point of the spiral steel pipe when it moves down. Because the shearing point of the spiral steel pipe is not supported, the shearing point of the spiral steel pipe is tilted, resulting in uneven incisions of the spiral steel pipe after shearing, thereby affecting the efficiency of shearing the spiral steel pipe. Utility Model Content

[0004] The utility model aims to solve the problem that the shearing equipment in the prior art can only clamp spiral steel pipes of one specification, and proposes a shearing and forming device for anti-corrosion plastic-coated spiral steel pipes.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for shearing and forming an anti-corrosion plastic-coated spiral steel pipe comprises a base, a lifting cutting head and a ruler, wherein the base is provided with a matching guide rail and a slider, and a bracket is integrally connected between the two sliders, and the ruler is arranged on the bracket, a connecting plate is fixedly installed on the bracket, and a symmetrically arranged connecting frame and a telescopic rod are respectively fixedly installed on the connecting plate, and the lifting cutting head is arranged on the connecting plate;

[0007] A lower clamping plate is detachably mounted on the connecting frame, a sleeve is fixedly connected to the output end of the telescopic rod, and a connecting end is placed in the sleeve, an upper clamping plate corresponding to the lower clamping plate and used to limit the spiral steel pipe is integrally connected to the connecting end, and a soft cushion is provided between the upper clamping plate and the lower clamping plate to resist the spiral steel pipe.

[0008] Preferably, a support for supporting the spiral steel pipe is fixedly mounted on the base, and a limit plate movably abutting against the end of the spiral steel pipe is placed on the base.

[0009] Preferably, symmetrically arranged connecting ears are fixedly mounted on the lower clamping plate, and locking bolts detachably connected to the connecting frame are threadedly connected to the connecting ears.

[0010] Preferably, the upper clamping plate and the connecting end extend to the lower end position outside the sleeve, and a fixing bolt detachably connected to the connecting end is threadedly connected to the sleeve.

[0011] Preferably, the upper clamping plate and the lower clamping plate are both arc-shaped structures compatible with the spiral steel pipe, and a collecting frame for collecting debris is integrally connected between the two connecting frames.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model realizes detachable installation of the upper clamping plate and the lower clamping plate, so that the upper clamping plate and the lower clamping plate can limit the spiral steel pipes of different specifications, thereby increasing the adaptability of the spiral steel pipe equipment, and also when the upper clamping plate and the lower clamping plate limit the spiral steel pipe, the stability of the spiral steel pipe during shearing can be guaranteed.

[0014] 2. The utility model can drive the two connecting frames to move through the movement of the bracket, so that the two connecting frames drive the upper clamping plate and the lower clamping plate to limit and support the two ends of the shearing point of the spiral steel pipe, so that the spiral steel pipe will not be deformed due to the downward movement of the lifting cutting head during cutting, thereby ensuring the aesthetics of the spiral steel pipe after shearing.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A device for shearing and forming an anti-corrosion plastic-coated spiral steel pipe comprises a base 1, a lifting cutting head, and a ruler 4. A support 14 for supporting the spiral steel pipe is fixedly installed on the base 1. A limit plate 15 that is movably abutted against the end of the spiral steel pipe is placed on the base 1. The movable spiral steel pipe can be supported by the support 14. When the spiral steel pipe extends between the upper clamping plate 12 and the lower clamping plate 8, the end of the spiral steel pipe can be movably abutted against the limit plate 15.

[0022] The base 1 is provided with a matching guide rail and a slider, and a bracket 2 is integrally connected between the two sliders, and a ruler 4 is provided on the bracket 2, a connecting plate 3 is fixedly installed on the bracket 2, and a symmetrically arranged connecting frame 5 and a telescopic rod 6 are fixedly installed on the connecting plate 3, respectively, and a lifting cutting head is provided on the connecting plate 3. It is supplemented that the guide rail and the slider can realize the movement of the bracket 2 as an existing technology;

[0023] A lower clamping plate 8 is detachably mounted on the connecting frame 5, and symmetrically arranged connecting ears 9 are fixedly mounted on the lower clamping plate 8, and a locking bolt detachably connected to the connecting frame 5 is threadedly connected to the connecting ears 9;

[0024] The output end of the telescopic rod 6 is fixedly connected with a sleeve 10, and a connecting end 11 is placed in the sleeve 10. The connecting end 11 is integrally connected with an upper clamping plate 12 corresponding to the lower clamping plate 8 and used to limit the spiral steel pipe. The upper clamping plate 12 and the connecting end 11 extend to the lower end position outside the sleeve 10, and the sleeve 10 is threadedly connected with a fixing bolt that is detachably connected to the connecting end 11.

[0025] By limiting the spiral steel pipe from both sides by the upper clamping plate 12 and the lower clamping plate 8, the contact area between the upper clamping plate 12, the lower clamping plate 8 and the spiral steel pipe can be increased, and before the spiral steel pipe is clamped, the specifications of the upper clamping plate 12 and the lower clamping plate 8 are first selected so that the upper clamping plate 12 and the lower clamping plate 8 can fit the spiral steel pipe after moving, so that the shearing equipment can limit the spiral steel pipes of different specifications, thereby increasing the adaptability of the shearing equipment;

[0026] A cushion 13 is provided between the upper clamping plate 12 and the lower clamping plate 8 to resist the spiral steel pipe. The upper clamping plate 12 and the lower clamping plate 8 are arc-shaped structures adapted to the spiral steel pipe. By setting the upper clamping plate 12 and the lower clamping plate 8 as arc-shaped structures adapted to the spiral steel pipe, the contact degree between the upper clamping plate 12, the lower clamping plate 8 and the spiral steel pipe can be increased. By arranging the cushion 13 on the upper clamping plate 12 and the lower clamping plate 8, the upper clamping plate 12 and the lower clamping plate 8 will not cause pressure damage to the spiral steel pipe when clamping the spiral steel pipe. A collection frame 7 for collecting debris is integrally connected between the two connecting frames 5.

[0027] The upper clamping plate 12 and the lower clamping plate 8 on the two connecting frames 5 can support both ends of the shearing point of the spiral steel pipe, so that the shearing points of the spiral steel pipe are supported during shearing, so that the spiral steel pipe will not tilt during shearing, and the incision of the spiral steel pipe is flush after cutting;

[0028] It should be noted that the specific models and specifications of the telescopic rod 6 and the lifting cutting head need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] The sizes of the upper clamping plate 12 and the lower clamping plate 8 are selected according to the specifications of the spiral steel pipe;

[0031] After the upper clamping plate 12 is selected, the connecting end 11 equipped with the upper clamping plate 12 is extended into the sleeve 10, and the sleeve 10 and the connecting end 11 are connected by a fixing bolt;

[0032] After the lower clamping plate 8 is selected, the connecting ear 9 equipped with the lower clamping plate 8 is placed on the connecting frame 5, and the connecting ear 9 is connected to the connecting frame 5 using a locking bolt;

[0033] Place the spiral steel pipe on the support 14 and extend it into the base 1. The spiral steel pipe continues to move and extends between the upper clamping plate 12 and the lower clamping plate 8, so that the end of the spiral steel pipe and the limit plate 15 are movable against each other.

[0034] The guide rail and the slider cooperate with each other to drive the bracket 2 to move, so that the bracket 2 drives the connecting plate 3, the upper clamping plate 12, the lower clamping plate 8, and the lifting cutting head to move. The length of the spiral steel pipe can be measured by the ruler 4, so that the lifting cutting head can move to a position above the shearing point of the spiral steel pipe;

[0035] The output ends of the two telescopic rods 6 drive the sleeve 10 to move downward, so that the sleeve 10 drives the connecting end 11 and the upper clamping plate 12 to move downward, so that the upper clamping plate 12 can press the spiral steel pipe from the top position, so that both ends of the shear point of the spiral steel pipe are limited by the upper clamping plate 12 and the lower clamping plate 8;

[0036] The lifting cutting head cuts the spiral steel pipe, and the debris generated when the spiral steel pipe is cut can be collected by the collecting frame 7.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
