Description

Technical Field

[0001] This utility model relates to the technical field of cutting, specifically to a tube sheet cutting device. Background Technology

[0002] Tube sheets use steel pipes and plates of different lengths during use, but the length of steel pipes and plates produced in general is constant, so they need to be cut to the required length. Before cutting, they need to be fixed.

[0003] For example, Chinese utility model patent CN108326362A discloses a plate and tube cutting device for easy material fixing, including a support base. A cutting machine is connected to the upper surface of the support base. A lead screw groove is formed on the upper surface of the support base, and a lead screw is installed in the groove. Bearings are provided in opposite sidewalls of the groove. Both ends of the lead screw extend into the bearings, and one end of the lead screw passes through the bearing and extends outward from the support base. Symmetrically arranged threads with opposite directions are provided on the lead screw. A lead screw nut is symmetrically arranged on the lead screw, and a clamping block is connected to the upper end of the lead screw nut. Buffer devices are provided on the opposite sidewalls of the two clamping blocks, and a clamp is connected to the end of the buffer device away from the clamping block. This invention has a simple structure, is easy to operate, and is very convenient. It tightly clamps the plate and tube between the clamps, improving work efficiency and reducing the adverse effects of vibration during the cutting process on the fixing of the plate and tube.

[0004] However, since the pipe is cylindrical, it is not convenient to fix the outer wall of the pipe in the same way as fixing plates, which reduces the fixing effect of the device on the pipe and thus affects the cutting effect of the device on the pipe. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tube sheet cutting device that improves the fixing effect of the device before the tube sheet cutting operation, prevents the tube sheet from moving during the cutting process, improves the cutting effect of the subsequent device on the tube sheet, and enhances its practicality.

[0006] This utility model discloses a tube sheet cutting device, including a support platform, a support block fixedly installed on one side of the top of the support platform, a fixing mechanism provided at the top of the support block, and a cutting mechanism fixedly installed at the top of the support platform through a sliding mechanism; the fixing mechanism includes a top plate, a first sliding groove is opened at the top of the support block, a sliding plate is slidably installed inside the first sliding groove, the bottom end of the sliding plate is fixedly connected to the bottom end of the first sliding groove through multiple springs, and two support mechanisms are symmetrically arranged at the top of the sliding plate; The support mechanism includes two rotating plates, which are symmetrically fixedly installed on the top of the slide plate.

While rotating the first screw, the limiting plate and clamping plate are moved synchronously. The bottom end of the clamping plate contacts the tube sheet, thus fixing the tube sheet. The sliding mechanism drives the cutting mechanism to cut the tube sheet. This improves the device's ability to fix the tube sheet before cutting, preventing movement during cutting and improving the subsequent cutting effect, thus enhancing practicality.

[0007] Preferably, the sliding mechanism includes two limiting posts, which are symmetrically fixedly installed on the top of the support platform. Each limiting post has a sliding rod fixedly installed on its top, and a slider is slidably installed on each sliding rod. The tops of the two sliders are fixedly connected by a connecting block. A second sliding groove is provided on the connecting block, and a cutting mechanism is provided on the second sliding groove. When the slider slides on the limiting post, it simultaneously drives the connecting block and the cutting mechanism on the connecting block to slide.

[0009] Preferably, a baffle is fixedly installed at one end of each of the two upright plates. A first connecting groove and a second connecting groove are respectively opened on the outer side wall of the baffle. By installing the baffle, it is convenient to limit the cutting of the tube sheet. By opening the first connecting groove, it is convenient to limit the plate material. By opening the second connecting groove, it is convenient to limit the pipe material.

[0010] Preferably, two anti-slip strips are symmetrically fixedly installed on the top of the support block, which facilitates the support operation of the tube sheet.

[0011] Preferably, a support plate is fixedly installed at the top of the support platform, and a limiting groove is opened in the middle area of ​​the support plate.

[0012] Preferably, an extension plate is fixedly installed on the outer side wall of each connecting block, and a third screw is longitudinally screwed onto each extension plate. A clamping plate is rotatably installed at the bottom end of each third screw, and the bottom end of each clamping plate is tightly fitted with the top end of two limiting posts. By rotating the third screw, the clamping plate is simultaneously driven to tightly fit with the top end of the limiting posts, thereby completing the limiting operation of the sliding slider.

[0013] Preferably, one of the limiting posts has a through hole, which facilitates the loading and unloading of the collection tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This tube sheet cutting device, through the extension of the spring, synchronously drives the sliding plate, rotating plate and support roller to support the operation. The rotating support roller contacts the tube sheet, thereby performing the initial support operation on the tube sheet.
