Abstract
Description
Technical Field
[0001] This utility model relates to the field of corner cutting equipment technology, and in particular to a pipe corner trimming device. Background Technology
[0002] When pipes are spliced into various shapes, it is often necessary to trim and cut the corners of the pipes to ensure a smooth and beautiful surface after welding, which is convenient for forming different shapes. The current pipe corner processing usually uses conventional cutting saw blades for manual cutting, which has poor cutting accuracy, long measurement time, and is also prone to causing dangers such as splashing during cutting. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a pipe corner trimming device in response to the above-mentioned technical deficiencies. The device uses a punch with an anvil and a feeding hole to quickly cut the corner of the pipe, which solves the problems of poor cutting accuracy, long measurement time and the risk of splashing during cutting.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a pipe corner trimming device, including a fixed frame, a slide seat provided on the upper side of the frame, the slide seat being slidably connected within the frame, a lead screw passing vertically through the frame, the lead screw being threadedly connected to the slide seat, a sliding slider provided at the bottom of the slide seat, a shearing seat provided at the bottom of the slider, a lifting drive mechanism provided at the top of the slider, a punch provided at the bottom of the shearing seat, the punch having an isosceles triangular cross-section, an anvil provided below the shearing seat, a trimming cavity provided at the position corresponding to the punch, and feeding holes passing through the left and right sides of the anvil, the feeding holes being intersected with the trimming cavity.
[0005] To further optimize this technical solution, a groove is provided at the bottom of the punch, and cutting blades are provided on both sides of the groove.
[0006] To further optimize this technical solution, a notch is provided at the top of the feeding hole, and the notch extends vertically between the top of the anvil and the feeding hole.
[0007] To further optimize this technical solution, a material drop plate is provided at the bottom of the anvil, and the material drop plate is located at the lower part of the trimming cavity.
[0008] Compared with the prior art, this utility model has the following advantages: 1. By selecting an anvil with a suitable diameter for the pipe to be cut, and cooperating with the up-and-down movement of the punch in the trimming chamber, the punch can cut the pipe. The feeding hole ensures that the position of the pipe does not move and avoids deformation of the pipe; 2. The cutting blade can cut the pipe at an angle, making the operation safe and efficient.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0014] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" used in this application to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings. They are used solely for the convenience of describing this disclosure and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0015] Combination Figures 1 to 3As shown, a pipe corner trimming device includes a fixed frame 1. A slide 2 is provided on one side of the upper part of the frame 1, and the slide 2 is slidably connected within the frame 1. A lead screw 11 runs vertically through the frame 1 and is threadedly connected to the slide 2. A sliding block 3 is provided at the bottom of the slide 2, and a shearing seat 5 is provided at the bottom of the block 3. A lifting drive mechanism is provided at the top of the block 3. The lifting drive mechanism can be manual, hydraulic, or pneumatic. In this embodiment, a pressure rod 4 is linked to a connecting plate 30 to drive the lifting and lowering of the block 3, thereby driving the punch 51 to achieve shearing. The punch 51 is provided at the bottom of the shearing seat 5. The cross-section of the punch 51 is an isosceles triangular structure, and the cross-section can be set to different shapes according to the shape of the pipe corner to be cut. A groove 52 is provided at the bottom of the punch 51, and cutting blades 53 are provided on both sides of the groove 52. Below the shearing seat 5 is an anvil seat 6. A trimming chamber 62 is located at the position corresponding to the punch 51 on the anvil seat 6. Feed holes 60 extend through the anvil seat 6 from left to right. The inner diameter of the feed holes 60 can be set differently according to the diameter of the tube to be cut. The feed holes 60 intersect with the trimming chamber 62. A discharge plate 63 is located at the bottom of the anvil seat 6, below the trimming chamber 62. A notch 61 is located at the top of the feed holes 60, extending vertically between the top of the anvil seat 6 and the feed holes 60.
[0016] When using, combine Figures 1 to 3 As shown, select an anvil 6 with a suitable diameter for the pipe to be cut, and fix the anvil 6 in the mounting platform of the frame 1 to ensure that the punch 51 can move smoothly up and down in the trimming chamber 62. The punch 51 always slides inside the trimming chamber 62. After installation, feed the pipe into the trimming chamber 62 through the feeding hole 60. After adjusting the length, press down the slider 3 and the punch 51 to move downward along the trimming chamber 62. The pipe is cut at an angle by the set cutting blade 53. The operation is safe and efficient.
