Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of product detection, and particularly relates to a product pull-off force test fixture. Background Art
[0002] The pull-off force refers to the force required to pull and separate the tube and the tube sheet after connection. The expansion rate is a measure of the degree to which the tube adheres to the inner wall of the tube sheet hole after expansion, and the unit is Pascal (Pa). For example, during the operation of a heat exchanger, it is subjected to the combined action of fluid pressure and the temperature difference stress of the tube shell wall. These two forces generate a pull-off force at the connection joint of the tube and the tube sheet, causing the tube and the tube sheet to tend to separate.
[0003] Pull-off force testing is a type of test that many tubular products need to undergo during the production process to detect product quality. The pull-off force test fixtures of the prior art have complex structures and cumbersome operation processes. Therefore, the problems brought about are: one is the relatively high purchase cost, which will increase the company's testing costs; the other is that professional technical personnel are required to operate, which will increase the company's labor costs. Content of the Utility Model
[0004] The purpose of the utility model is to provide a product pull-off force test fixture to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A product pull-off force test fixture, including a base, one side of the base is provided with a mounting beam, the mounting beam and the base are arranged at an angle of 70°, the base is provided with a support frame, the support frame and the mounting beam are cross-connected, the mounting beam is provided with a support plate, the support plate and the support frame are cross-connected, the support frame is provided with a placement frame, both sides of the placement frame are provided with a first through hole and a second through hole at the same horizontal position, the upper end of the placement frame is provided with a baffle, and the baffle is provided with a pulling port.
[0006] Preferably, a fastening plate is provided between the mounting beam and the support frame.
[0007] Preferably, the mounting beam and the base are integrally formed.
[0008] Preferably, the support plate and the mounting beam are connected by a plurality of socket head cap screws.
[0009] Preferably, the bottom end of the support plate is provided with a mounting step, and the height of the mounting step is equal to the thickness of the mounting beam.
[0010] Preferably, there are two pulling ports, and symmetrically distributed cylinders are provided on the bottom side of the pulling ports.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: By providing a base, a mounting beam, a support plate, a support frame and a placement frame, the present utility model has a simple structure, is strong and durable, and is easy to operate, which can significantly reduce the detection cost of enterprises.
