Description

Technical Field

[0001] This utility model relates to the field of square rail processing technology, specifically a box-type resistance furnace for square rail processing. Background Technology

[0002] Square rail machining refers to the precision machining process of linear guides with square cross-sections. It involves the cutting, assembly, and precision adjustment of components such as sliders and rails. It is mainly used in high-precision transmission systems of machine tools and automated equipment. During machining, a box-type resistance furnace is used to heat-treat the metal material to improve its performance. Square rails must possess high hardness, wear resistance, and dimensional stability, achieved through processes such as quenching and tempering. The box-type resistance furnace provides a controllable high-temperature environment to meet the heating requirements of materials such as carbon steel and alloy steel. The utility model disclosed in CN205046155U is a heat treatment resistance furnace. By setting a counterweight on the outside of the furnace body, the force required to turn the handle is reduced. At the same time, an insulation layer is provided on the outside of the furnace lining inside the furnace body to ensure that the temperature inside the furnace body is stable and does not easily dissipate. A baffle is set below the furnace door, and the baffle can be rotated through a support. The operator can rotate the baffle to the horizontal direction by pulling the rod, so that the residual oxide layer on the bottom surface of the furnace body can be directly cleaned.

[0003] However, the above-disclosed resistance furnaces for heat treatment still have the following problems in actual use: the resistance furnace heats the square rails and workpieces, but the heating mechanism requires manual loading and unloading. Some square rail workpieces do not have corresponding clamping parts when loading and unloading, and the heating chamber of the resistance furnace cannot be effectively observed during loading and unloading, thus affecting the loading and unloading efficiency.

[0004] Therefore, we propose a box-type resistance furnace for square rail processing to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a box-type resistance furnace for square rail processing. This solves the problem that existing resistance furnaces heat square rails and workpieces, but these heating mechanisms require manual loading and unloading during operation. Some square rail workpieces do not have corresponding clamping parts when being loaded or unloaded, and the heating chamber of the resistance furnace cannot be effectively observed during loading and unloading, thus affecting the loading and unloading efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a box-type resistance furnace for square rail processing, comprising a furnace body and heat dissipation grilles on the left and right sides below the furnace body, and an operation panel on the lower front of the furnace body; a heating mechanism is provided above the furnace body, and the heating mechanism includes a heating box and a protective door; a pushing mechanism is provided inside the heating box, and the pushing mechanism includes a placement platform, and filter slag grooves are evenly spaced inside the placement platform.

[0007] Preferably, the heating mechanism includes a heating box that is fixedly installed at the center of the upper part of the resistance furnace body, and the heating box has a heating cavity inside. The heating box and the heating cavity are used to store the placed square rails and realize resistance heating processing.

[0008] Preferably, the heating mechanism includes a protective partition door that is hinged to the front of the resistance furnace body, and the protective partition door is closed by rotating to the opening on the front of the heating chamber, thereby isolating heat during heating operations and improving heating efficiency.

[0009] Preferably, the pushing mechanism includes guide grooves, which are opened on the left and right sides of the lower part of the heating box. Guide rods are fixedly installed inside the guide grooves on both sides, and guide sliders are slidably provided through the outer wall of the guide rods.

[0010] Preferably, the top end of the guide slider included in the pushing mechanism is fixedly disposed on the left and right sides behind the bottom surface of the storage platform, and the symmetrically arranged guide sliders and the front end of the guide slide rod are connected to each other by a return spring. Moreover, the storage platform and the protective partition door are in contact with each other so as to move when the protective partition door is opened, closed and shut.

[0011] Preferably, the pushing mechanism includes a slag-blocking horizontal plate, with the rear end of the slag-blocking horizontal plate fixedly installed inside the lower part of the heating box, and the front end of the slag-blocking horizontal plate inserted into the inside of the placement platform, thereby sealing the filter slag trough to prevent slag from remaining inside the heating box.

[0012] Preferably, the pushing mechanism includes a slag collection hopper, which is fixedly installed inside the lower part of the electric resistance furnace body. The upper opening of the slag collection hopper corresponds to the slag filter troughs distributed inside the placing platform, which are used to discharge slag through the slag filter troughs downward when the placing platform pushes the material forward, and collect it by the slag collection hopper.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This box-type resistance furnace for square rail processing uses a loading platform inside the heating chamber to support the square rail workpiece and slides during processing and handling, improving the convenience of handling operations. Simultaneously, after the slag filter trough is opened, the slag inside is fed downwards and collected by the slag collection hopper, preventing residue from remaining inside the resistance furnace body and affecting its service life. The specific details are as follows: 1. Rotate to open the protective partition door on the front of the resistance furnace body so that the unobstructed placement platform can slide forward through the extension of the return spring at the bottom and move to the front outer wall of the heating chamber. The placement platform is not covered by the resistance furnace body, which facilitates the loading and unloading of square rail workpieces.

[0014] Furthermore, the square rail workpiece is placed on the top surface of the storage platform, and after the protective partition door is rotated, it comes into contact with the storage platform, causing the square rail workpiece to move backward into the heating chamber inside the heating box, facilitating subsequent heating operations.

[0015] 2. The placement platform moves backward into the heating chamber, and the inserted slag-blocking horizontal plate seals the filter slag trough so that the slag falling during the square rail heating operation can be stored on the top of the placement platform, preventing the slag from falling into the heating chamber and affecting subsequent heating operations.

[0016] Furthermore, the platform is moved to the front, and the inserted slag-blocking horizontal plate no longer seals the slag chute. Instead, the slag is fed downwards into the slag collection hopper through the open slag chute to improve the efficiency of the heating operation and extend the service life of the electric resistance furnace.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-7 The present invention provides the following technical solution: Example 1: To address the problems existing in the use of current resistance furnaces for square rail processing, this example discloses the following technical solution: a box-type resistance furnace for square rail processing, comprising a furnace body 1 and heat dissipation grilles 2 located on the left and right sides below the furnace body 1, and an operation panel 3 located on the lower front of the furnace body 1; and a heating mechanism including a protective door 5, the protective door 5 being hinged to the front of the furnace body 1, and the protective door 5 being rotated to close the opening on the front of the heating chamber 4, thereby isolating heat during heating operations and improving heating efficiency.

[0021] The heating mechanism includes a heating box 4 which is fixedly installed at the center of the upper part of the resistance furnace body 1. The heating box 4 has a heating cavity 8 inside. The heating box 4 and the heating cavity 8 are used to store the placed square rails and realize resistance heating processing. The heating mechanism is provided on the upper part of the resistance furnace body 1. The heating mechanism includes a heating box 4. The heating box 4 has a pushing mechanism inside. The pushing mechanism includes a placement platform 6.

[0022] The pushing mechanism includes guide slides 9, which are located on the left and right sides of the lower part of the heating box 4. Guide slide rods 10 are fixedly installed inside the guide slides 9 on both sides, and guide sliders 11 are slidably installed through the outer wall of the guide slide rods 10. The top of the guide sliders 11 included in the pushing mechanism is fixedly located on the left and right sides behind the bottom surface of the storage platform 6. The symmetrically arranged guide sliders 11 and the front end of the guide slide rods 10 are connected to each other by a return spring 14. The storage platform 6 and the protective partition door 5 are in contact with each other so as to move when the protective partition door 5 is opened, closed and shut.

[0023] like Figures 1-2, Figure 4 As shown, when the square rail needs to be heated and processed by the resistance furnace body 1, the protective partition door 5 hinged to the front of the resistance furnace body 1 is first opened by manually rotating it outward. The protective partition door 5 abuts against the placement platform 6 inside the heating chamber 4 through its inner wall, so that the protective partition door 5 no longer abuts against the placement platform 6 after it is opened. The guide slider 11 on the bottom surface of the placement platform 6 is slidably sleeved on the outer wall of the guide slide rod 10 through the return spring 14, so that after the return spring 14 extends, it drives the guide slider 11 and the placement platform 6 to slide forward, so that the placement platform 6 moves to the outside of the heating chamber 4, which facilitates the improvement of the efficiency and accuracy of picking up and putting down materials before and after the square rail processing operation.

[0024] Furthermore, after placing the square rail workpiece above the placement platform 6, the protective partition 5 is manually rotated backward to close to the front of the resistance furnace body 1. At the same time, the protective partition 5 abuts against the front end of the placement platform 6, thereby causing the placement platform 6 and the square rail workpiece above to move synchronously into the heating chamber 8 inside the heating box 4, which facilitates subsequent heating and processing operations.

[0025] Example 2: In order to solve the problems existing in the use of the existing resistance furnace for square rail processing, this example discloses the following technical solution: the inside of the placement platform 6 is provided with filter slag grooves 7 at equal intervals, the pushing mechanism includes a slag blocking plate 12, and the rear end of the slag blocking plate 12 is fixedly installed inside the lower part of the heating box 4, and the front end of the slag blocking plate 12 is inserted into the inside of the placement platform 6, and the filter slag grooves 7 are sealed to prevent slag from remaining inside the heating box 4.

[0026] The pushing mechanism includes a slag collection hopper 13, which is fixedly installed inside the lower part of the electric resistance furnace body 1. The upper opening of the slag collection hopper 13 corresponds to the slag filter trough 7 distributed inside the placing platform 6. It is used to put the slag down through the slag filter trough 7 when the placing platform 6 pushes the material forward, and collect it by the slag collection hopper 13.

[0027] like Figure 4 , Figures 6-7 As shown, a slag-blocking horizontal plate 12 is fixedly installed inside the heating box 4 so that after the placement platform 6 moves backward into the heating box 4, the inserted slag-blocking horizontal plate 12 will seal the slag filter groove 7 opened inside the placement platform 6, so that the slag falling during the square rail heating operation can be stored above the placement platform 6, and the slag will be prevented from falling into the heating box 4 and affecting the subsequent heating operation.

[0028] Furthermore, after the placement platform 6 moves the square rail workpiece above it forward to the outside of the heating box 4, the slag-blocking horizontal plate 12 inserted inside the placement platform 6 no longer seals the slag filter trough 7, so that the gradually opening slag filter trough 7 is always outside the heating box 4, and the slag material is thrown down into the slag collection hopper 13 for collection through the opening slag filter trough 7, so as to improve the efficiency of the heating operation and the service life of the resistance furnace body 1.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
