Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat treatment technology for metal workpieces, specifically to a testing device for metal workpieces after heat treatment. Background Technology
[0002] In the production and processing of metal workpieces such as automotive parts, molds and structural components, heat treatment processes such as quenching and tempering are usually required to change the internal structure and properties of the metal workpieces, improve their mechanical properties, wear resistance, corrosion resistance, etc., and ensure that the workpieces have the required performance and lifespan in use.
[0003] Currently, some heat-treated metal workpieces, due to precision requirements, may undergo oxidation and decarburization on the metal surface after high-temperature heat treatment (such as normalizing, annealing, carburizing, and tempering), forming oxide scale or losing some material. This requires personnel to place them on a weighing device to assess material loss, ensure accurate workpiece quality, and transfer qualified metal workpieces to the next process.
[0004] Currently, the weighing process for metal workpieces mainly relies on manual handling to place them onto the weighing device, weigh and classify them, and repeat this operation for batch inspection of metal workpieces. This process is time-consuming, labor-intensive, and cumbersome, which is not conducive to the production and processing of large quantities of workpieces.
[0005] Based on this, this utility model designs a testing device for metal workpieces after heat treatment to solve the above problems. Summary of the Invention
[0006] The purpose of this invention is to provide a testing device for metal workpieces after heat treatment, so as to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a metal workpiece heat treatment inspection device, comprising: an input conveyor belt, an inspection frame, and an output conveyor belt; the inspection frame is respectively fixed to the output end of the input conveyor belt and the input end of the output conveyor belt, and the inspection frame includes a weighing device disposed on the top, a pulling mechanism disposed on the top of the inspection frame, and a pushing mechanism;
[0008] The pulling mechanism includes a first electric cylinder fixed to one end of the detection frame, a pull plate connected to one end of the telescopic shaft of the first electric cylinder, and an electromagnet disposed on the outer wall of the pull plate;
[0009] The pushing mechanism includes a second electric cylinder fixed to one end of the testing frame and a push plate that is connected to one end of the telescopic shaft of the second electric cylinder.
[0010] Preferably, a main control box is fixed at the bottom of the testing frame, and the main control box is equipped with a controller that connects the weighing device, the first electric cylinder, the second electric cylinder and the electromagnet.
[0011] Preferably, the testing frame has a material discharge port near the top of the weighing device.

[0013] Preferably, one end of the testing frame is fixed with a bracket, and one end of the bracket is fixed to the tail end of the first electric cylinder.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] Large quantities of magnetically attracted metal workpieces can be placed sequentially on the input conveyor belt and transported to the top of the inspection frame. The weighing device measures the weight, and workpieces that meet the weight setting standard are pushed by the push plate controlled by the second electric cylinder to the output conveyor belt for transfer. Workpieces that do not meet the weight setting standard are attracted by the electromagnet and pulled to the material drop position of the inspection frame for processing. The inspection process saves manpower, is simple, fast and more accurate, and is suitable for the inspection of large batches of workpieces. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a metal workpiece heat treatment inspection device, including: an input conveyor belt 1, an inspection frame 2 and an output conveyor belt 12; the inspection frame 2 is fixed to the output end of the input conveyor belt 1 and the input end of the output conveyor belt 12 respectively, and the inspection frame 2 includes a weighing device 3 set on the top, a pulling mechanism and a pushing mechanism set on the top of the inspection frame 2;
[0025] The pulling mechanism includes a first electric cylinder 4 fixed to one end of the testing frame 2, a pull plate 5 connected to one end of the telescopic shaft of the first electric cylinder 4, and an electromagnet 6 disposed on the outer wall of the pull plate 5.
[0026] The pushing mechanism includes a second electric cylinder 7 fixed to one end of the testing frame 2 and a push plate 8 that is connected to one end of the telescopic shaft of the second electric cylinder 7.
[0027] The input conveyor belt 1 serves as a component for transporting metal workpieces toward the inspection frame 2. It sequentially transports batches of metal workpieces to the inspection frame 2. Simultaneously, the electromagnet 6 in the pulling mechanism attracts the workpieces that have just arrived at the inspection frame 2, allowing them to be smoothly moved to the middle position of the weighing panel of the weighing device 3 for weight detection. The weighing panel of the weighing device 3 is horizontally higher than the top surface of the inspection frame 2 and the output conveyor belt 12, but lower than the input conveyor belt 1, the pull plate 5, and the push plate 8 to meet the weighing drop requirements. This does not affect the movement of the metal workpieces, the pull plate 5, and the push plate 8. If the weighing device 3 weighs the workpieces that pass the test, the L-shaped push plate 8 controlled by the second electric cylinder 7 will push them to the output conveyor belt 12 for output. If the workpieces fail the test, the pull plate 5 will pull the weighing device 3 away.
[0028] More preferably, a main control box 13 is fixed at the bottom of the testing frame 2, and a controller connected to the weighing device 3, the first electric cylinder 4, the second electric cylinder 7 and the electromagnet 6 is installed in the main control box 13;
[0029] The main control box 13 at the bottom of the testing frame 2 receives, processes, and transmits signals from the weighing device 3, the first electric cylinder 4, the second electric cylinder 7, and the electromagnet 6 through an internal controller, controlling the coordinated operation of each connected component.
[0030] Preferably, the top of the testing frame 2 near the weighing device 3 has a material discharge port 9;
[0031] The material drop port 9 of the detection frame 2 corresponds to the waste drop position of the electromagnet 6, and a waste bin can be placed below for collection.
[0032] More preferably, the top of the input conveyor belt 1 is provided with two symmetrical limiting baffles 10;
[0033] The input conveyor belt 1 is protected from metal workpiece displacement by two limit baffles 10 and is directly facing the moving contact electromagnet 6.
[0034] More preferably, one end of the testing frame 2 is fixed with a bracket 11, and one end of the bracket 11 is fixed to the tail end of the first electric cylinder 4;
[0035] The bracket 11 ensures the stability of the first electric cylinder 4, enabling it to stably control the operation of the pull plate 5.
[0036] One specific application of this embodiment is as follows: A large batch of magnetically attracted metal workpieces to be inspected can be placed sequentially between the two limiting baffles 10 of the input conveyor belt 1, and transported by the input conveyor belt to the top of the inspection frame 2. They first come into contact with the magnetic end of the electromagnet 6 on the outer wall of the pull plate 5. After the electromagnet 6 contacts the metal workpiece, it attracts it. By pulling the first electric cylinder 4, it is pulled to the middle position of the inspection panel of the weighing device 3 of the inspection frame 2 and then released. After the weighing device 3 measures, the workpieces that meet the weight setting standard will be pushed by the push plate 8 controlled by the second electric cylinder 7 and transferred to the output conveyor belt 12. The workpieces that do not meet the weight setting standard will be attracted by the electromagnet 6 again and pulled to the drop port 9 position of the inspection frame 2. Personnel can set up a waste bin below the drop port 9 in advance to collect the workpieces that fall from the drop port 9 after the magnetic attraction is broken.
