Description

Technical Field

[0001] This utility model relates to the field of header processing equipment technology, and in particular to a header pipe cutting machine. Background Technology

[0002] The header consists of a main body, and the sides of the main body usually have one or more rows of branch pipes. When welding the branch pipes, due to the certain error in the depth of the branch pipes inserted into the main body, the ends of the branch pipes on the side of the header are not in the same plane. Therefore, it is necessary to cut a part of the end of the branch pipe so that the end of the branch pipe away from the main body of the header is flush.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a header pipe cutting machine to cut a portion of the end of a branch pipe, thereby meeting the requirement that the end of the branch pipe on the side away from the header body be flush.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A header pipe cutting machine includes: a base; a sliding assembly disposed on one side of the upper width direction of the base, the upper end of which has a sliding plate capable of sliding along the length direction of the sliding assembly; a cutting machine hinged to the sliding plate of the sliding assembly, capable of rotating about the hinge axis in a vertical plane parallel to the length direction of the base, the blade of the cutting machine being parallel to the length direction of the base; a support mechanism including: two brackets respectively disposed at both ends of the base along its length direction and located on the side of the sliding assembly; a first support rod and a second support rod fixed to the base, the second support rod being located on the side of the first support rod; a header including: a main body, both ends of which are snapped onto the brackets; a fixing plate disposed on one side of the main body and horizontally supported on the first support rod; and a branch pipe disposed on the other side of the main body and horizontally supported on the second support rod.

[0007] A further technical solution is that the base includes a hollow frame, and several horizontal bars are spaced apart along the length of the hollow frame. The first support bar and the second support bar are fixed to the front end or the rear end of the horizontal bars.

[0008] A further technical solution is that an arc-shaped groove is opened at the upper end of the bracket, the inner diameter of the groove is the same as the outer diameter of the main body, and the corresponding central angle is 180°.

[0009] A further technical solution is that the sliding component includes: two sets of slide rails, which are disposed on the base, parallel to the length direction of the base, and located on the right side of the upper end of the base; two sliders, which are respectively engaged with the slide rails and can slide along the slide rails; and a sliding plate, which is fixed to the upper end of the two sliders.

[0010] A further technical solution is to provide support feet at the four corners of the lower end of the base.

[0011] A further technical solution is that a waist-shaped hole is vertically opened on the first support rod and the second support rod, and two bolts are threaded through the crossbar and the waist-shaped hole in sequence to be connected to the nut.

[0012] A further technical solution is that the front side of the front bracket is flush with the front side of the sliding component, and the rear bracket is located on the front side of the rear end of the sliding component.

[0013] A further technical solution is that the number of the first support rods corresponds to the number of the fixed plates.

[0014] The beneficial effects of this utility model embodiment are as follows:

[0015] (I) The header pipe cutting machine of this utility model restricts the left and right movement of the header by snapping the front and rear ends of the header body into the upper end of the bracket. The fixing plate on one side of the header is horizontally supported on the first support rod, and the branch pipe on the other side of the header is horizontally supported on the second support rod, thus restricting the rotation of the header. The operator lifts the cutting machine and starts it. The cutting machine drives the blade to rotate, cutting the branch pipe while pushing the cutting machine and the slide plate to slide along the slide rail to the rear end, thereby cutting the header branch pipe and ensuring that the end of the branch pipe away from the header body is flush.

[0016] (ii) Furthermore, support feet are provided at the four corners of the lower end of the base. The support feet elevate the base, providing vertical movement space for the first and second support rods. The first and second support rods have vertical through-holes. Two bolts pass through the crossbar and the through-holes in sequence and are threaded to the nuts, ensuring that the first and second support rods are vertically set while their height can be adjusted according to the size of the fixing plate.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Example:

[0024] This embodiment discloses a header pipe cutting machine.

[0025] like Figure 1 As shown, the header pipe cutting machine includes a base 1, a sliding assembly 3, a cutting machine 2, a support mechanism 4, and a header 5.

[0026] Base 1 is placed on the ground. For example... Figure 2 As shown, for example, the base 1 includes a square hollow frame 11, and a plurality of crossbars 12 are arranged at intervals along its length inside the hollow frame 11.

[0027] A sliding assembly 3 is disposed on one side of the upper width direction of the base 1, and has a slider 32 at its upper end that can slide along the length direction of the sliding assembly 3. The cutter 2 is hinged to the slide plate 33 of the sliding assembly 3, and the blade of the cutter 2 is parallel to the length direction of the base 1. Exemplarily, the sliding assembly 3 includes a slide rail 31, a slider 32, and a slide plate 33. Two sets of slide rails 31 are disposed on the base 1, parallel to the length direction of the base 1, and located on the right side of the upper end of the base 1. Two sliders 32 are respectively engaged with the two slide rails 31 and can slide along the slide rails 31. The slide plate 33 is fixed to the upper ends of the two sliders 32. The cutter 2 is a commercially available handheld cutter 2, capable of rotating about a hinge axis in a vertical plane parallel to the length direction of the base 1.

[0028] like Figure 2 and Figure 3As shown, the support mechanism 4 includes a bracket 41, a first support rod 42, and a second support rod 43. There are two brackets 41, respectively located on the front and rear sides of the upper end of the base 1, and situated on the side of the sliding assembly 3. The first support rod 42 and the second support rod 43 are fixed to the base 1, with the second support rod 43 located on the right side of the first support rod 42. The header 5 includes a main body 51, a fixing plate 52, and a branch pipe 53. Both ends of the main body 51 are snapped onto the bracket 41. The fixing plate 52 is located on the left side of the main body 51, horizontally supporting the first support rod 42. The branch pipe 53 is located on the right side of the main body 51, horizontally supporting the second support rod 43. For example, an arc-shaped groove is formed at the upper end of the bracket 41, with the inner diameter of the groove being the same as the outer diameter of the main body 51, and the corresponding central angle being 180°. The header 5 main body 51 is snapped into the groove, restricting the left and right movement of the header 5. The first support rod 42 and the second support rod 43 are fixed to the front or rear end of the crossbar 12. The specific position, height, and thickness of the first support rod 42 are adjusted according to the position and size of the fixing plate 52 of the header 5, and the specific position, height, and thickness of the second support rod 43 are adjusted according to the position and size of the branch pipe 53 of the header 5. The number of first support rods 42 corresponds to the number of fixing plates 52.

[0029] like Figure 1 As shown, furthermore, support feet 13 are provided at the four corners of the lower end of the base 1. The support feet 13 elevate the base 1, providing vertical movement space for the first support rod 42 and the second support rod 43. A through-hole 421 is vertically formed on the first support rod 42 and the second support rod 43. Two bolts 422 pass through the crossbar 12 and the through-hole 421 in sequence and are threadedly connected to the nuts 423, ensuring that the first support rod 42 and the second support rod 43 are vertically positioned while their height can be adjusted according to the size of the fixing plate 52.

[0030] like Figure 2 As shown, the front side of the front bracket 41 is flush with the front side of the sliding assembly 3, and the rear bracket 41 is located in front of the rear end of the sliding assembly 3. Since the blade of the cutting machine 2 is located behind the slide plate 33, only when the rear bracket 41 is located in front of the rear end of the sliding assembly 3 can it be ensured that the blade can cut the last branch pipe 53 when the slide plate 33 slides to the rear end of the sliding assembly 3.

[0031] In this embodiment, by inserting both ends of the main body 51 of the header 5 into the upper end of the bracket 41, the left and right movement of the header 5 is restricted. The fixing plate 52 on the left side of the header 5 is horizontally supported on the first support rod 42, and the branch pipe 53 on the right side of the header 5 is horizontally supported on the second support rod 43, thus restricting the rotation of the header 5. The operator lifts and starts the cutting machine 2. The cutting machine 2 drives the blade to rotate, cutting the branch pipe 53 while pushing the cutting machine 2 and the slide plate 33 to slide along the slide rail 31 to the rear end, thereby cutting the branch pipe 53 of the header 5 and ensuring that the end of the branch pipe 53 away from the main body 51 of the header 5 is flush.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
