When the trolley annealing furnace is used in silicon steel production, it can eliminate work hardening, restore a certain plasticity of the material, and facilitate further processing. By controlling parameters such as heating temperature and time, the magnetic properties of silicon steel can be adjusted to meet the needs of different products; in addition, during the annealing process, the surface of silicon steel is oxidized to form an oxide film, which increases its corrosion resistance, improves surface quality, and further improves the stability and reliability of the product.

[0003] During the use of the trolley-type annealing furnace, the trolley and the workpiece will enter the furnace body for heating treatment together, which not only wastes energy, but also because the temperature in the furnace during annealing is as high as 600-900 degrees Celsius, it is easy to damage the overall structure of the trolley and the driving source that drives the trolley to move, affecting the service life of the trolley.

The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0032] like Figure 1-Figure 8 As shown, the trolley-type annealing furnace for silicon steel processing of the utility model comprises:

[0033] A furnace body 1, one side of which is vertically and openly arranged, a support member 11 is arranged on the inner bottom wall of the furnace body 1, the top surface of the support member 11 is a supporting surface, and a heating member 12 is also arranged in the furnace body 1;

The furnace door 2 in the closed position and the furnace body 1 enclose a furnace cavity isolated from the outside world. In the open position, the inner cavity of the furnace body 1 is connected to the outside world.

[0035] The trolley 4 and the track 5, the track 5 extends to be close to the open side of the furnace body 1, the trolley 4 moves on the track 5, and the top surface of the trolley 4 is a bearing surface located at the same level as the supporting surface;

[0036] The transfer frame 6 and the push-pull assembly 7, the transfer frame 6 is used to place silicon steel workpieces, the push-pull assembly 7 is arranged on the trolley 4, the push-pull assembly 7 drives the transfer frame 6 to translate, and the output end of the push-pull assembly 7 is detachably connected to the transfer frame 6 to drive the transfer frame 6 to move between the supporting surface and the bearing surface.

[0037] When the device is in use, in the initial state, the driving component 3 drives the furnace door 2 to move to the open position, so that the open side of the furnace body 1 is opened, the transfer rack 6 is placed on the bearing surface of the trolley 4, and the output end of the push-pull component 7 is connected to the transfer rack 6, and then the silicon steel workpiece to be annealed is placed on the transfer rack 6.

[0038] Afterwards, the trolley 4 moves along the track 5 to the open side close to the furnace body 1, and then the transfer rack 6 is pushed onto the supporting surface of the support member 11 in the furnace body 1 through the push-pull assembly 7. Then the push-pull assembly 7 is separated from the transfer rack 6, and then after leaving the furnace body 1, the driving assembly 3 drives the furnace door 2 to move to the closed position, so that the furnace door 2 and the furnace body 1 are enclosed to form a furnace chamber isolated from the outside world, and the heating element 12 is started to anneal the silicon steel workpiece in the furnace chamber.

[0039] After annealing is completed, the heating element 12 is turned off, and the furnace door 2 is driven to the open position by the driving component 3, so that the open side of the furnace body 1 is opened, and the push-pull component 7 on the trolley 4 is extended into the furnace body 1 and connected to the transfer rack 6, and the transfer rack 6 is pulled from the supporting surface of the support member 11 in the furnace body 1 to the bearing surface of the trolley 4, and then the annealed silicon steel workpiece is pulled out of the furnace body 1.

[0040] Compared with the prior art, the device does not require the trolley 4 to enter the furnace body when annealing the silicon steel workpiece, thereby avoiding the need to heat the trolley 4 and reducing the power consumption of the annealing process. In addition, only a single trolley 4 and a single track 5 are required, which cooperate with the push-pull assembly 7 to drive the transfer frame 6 to move in the furnace body 1 and on the trolley 4, thereby simplifying the overall structure and reducing costs.

[0041] In order to facilitate the movement of the furnace door 2 between the open position and the closed position, in the utility model, the furnace door 2 slides on the open side of the furnace body 1 along the vertical direction, and the driving component 3 is a lifting component. Specifically, the open side of the furnace body 1 is provided with a guide rail 13 extending along the vertical direction, and both sides of the furnace door 2 slide with the guide rail 13. The lifting component is a winch arranged on the top of the guide rail 13, and the steel cable of the winch is connected to the furnace door 2. Figure 1-4 As shown, the furnace door 2 is in the open position, and the winch pulls the steel cable to drive the furnace door 2 to move up and down along the guide rail 13, so that the furnace door 2 can move between the open position and the closed position. When the furnace door 2 is lowered to the lowest position, the furnace door 2 covers the open side of the furnace body 1, so that the furnace door 2 and the furnace body 1 are enclosed to form a furnace cavity, which is convenient for annealing the silicon steel workpiece in the furnace body 1.

[0042] A further improvement is that the extension direction of the track 5 is perpendicular to the open side of the furnace body 1, and the track 5 is facing the open side of the furnace body 1. With this design, when the trolley 4 moves to the end adjacent to the track 5 and the furnace body 1, the trolley 4 and the push-pull assembly 7 on the trolley 4 are facing the inner cavity of the furnace body 1, so that the push-pull assembly 7 can conveniently send the transfer rack 6 and the silicon steel workpiece on the transfer rack 6 into the furnace body 1, or after the annealing of the silicon steel workpiece is completed, the transfer rack 6 and the silicon steel workpiece on the transfer rack 6 are pulled back from the furnace body 1 to the trolley 4.

[0043] A further improvement is that the trolley 4 is provided with first rollers 41 distributed side by side, the tops of the first rollers 41 are combined to form a bearing surface, the support member 11 includes second rollers 111 distributed side by side, the tops of the second rollers 111 are combined to form a supporting surface, and the distribution direction of the first rollers 41 and the distribution direction of the second rollers 111 are both parallel to the extension direction of the track 5.

[0044] Second rollers 111 are arranged side by side at the bottom of the furnace body 1 , and the tops of the second rollers 111 form a supporting surface, which supports the transfer rack 6 and facilitates the movement of the transfer rack 6 , thereby reducing the wear of the transfer rack 6 when moving in the furnace body 1 .

[0045] The specific structure of the trolley 4 is as follows Figure 5 and Figure 6 As shown, the trolley 4 includes a base frame 43, and a traveling device 45 is arranged below the base frame 43. The traveling device 45 is used to drive the trolley 4 to move along the track 5. Two parallel roller frames 42 are fixed above the two sides of the base frame 43. The first roller 41 rotates around its own axis between the two roller frames 42. The top of the first roller 41 forms a bearing surface to support the transfer frame 6, which facilitates the movement of the transfer frame 6. A tail frame 44 is fixed to the end of the base frame 43 away from the furnace body 1, and the push-pull assembly 7 is arranged on the tail frame 44.

[0047] Specifically, the translation unit 71 is arranged on the tail frame 44, and the moving direction of the output end of the translation unit 71 is parallel to the extension direction of the track 5. The output end of the translation unit 71 is connected to the connecting unit 72, and the connecting unit 72 is detachably connected to the transfer frame 6, so that the push-pull assembly 7 can not only drive the transfer frame 6 to move between the supporting surface and the bearing surface, but also be separated and connected with the transfer frame 6.

[0048] A further improvement is that the transfer frame 6 includes two docking pieces 61 arranged relatively along a horizontal direction perpendicular to the extension direction of the track 5, and two connecting units 72 are provided and correspond one to one with the two docking pieces 61. The two connecting units 72 are both telescopic units, and the output end of the telescopic unit is plugged into and matched with the corresponding docking piece 61 along its own movable direction, and the telescopic direction of the telescopic unit is parallel to the distribution direction of the two docking pieces 61.

[0049] Through the telescopic movement of the telescopic unit, the plug-in cooperation with the transfer rack 6 is achieved. When the telescopic end of the telescopic unit is plugged into the docking piece 61 of the transfer rack 6, the telescopic unit is connected to the transfer rack 6, and then the transfer rack 6 can be driven to move along the extension direction of the track 5 through the translation unit 71. When the telescopic end of the telescopic unit is separated from the docking piece 61 of the transfer rack 6, the telescopic unit is separated from the transfer rack 6. When the translation unit 71 moves, it does not affect the position of the transfer rack 6.

[0050] A further improvement is that two docking pieces 61 are respectively arranged on both sides of the bottom of the transfer frame 6 and are arranged opposite to each other. After adopting the above design, when the telescopic unit is connected to the transfer frame 6, the two telescopic units enter between the two docking pieces 61, and the telescopic ends of the two telescopic units move away from each other in opposite directions and connect with their corresponding docking pieces 61, which is conducive to reducing the space occupied by the telescopic unit and making the push-pull assembly 7 more compact.

[0051] A further improvement is that the telescopic unit includes an insertion rod 721, a magnetic plate 722, an elastic member 723 and an electromagnet 724, the electromagnet 724 is fixed to the output end of the translation unit 71, the electromagnet 724 is connected to the magnetic plate 722 through the elastic member 723, the insertion rod 721 is fixedly connected to the magnetic plate 722 and the axial direction is consistent with the telescopic direction of the elastic member 723, the insertion rod 721 slides along its own axial direction at the output end of the translation unit 71, and a socket 611 for plugging and mating with the insertion rod 721 is provided on the docking member 61; a plurality of sockets 611 are provided, which are spaced apart along the movable direction parallel to the output end of the translation unit 71; a ball 725 is protruded from the end of the insertion rod 721 away from the electromagnet 724, and the ball 725 rotates around its own spherical center on the insertion rod 721.

[0052] Specifically, Figure 7 and Figure 8As shown, the translation unit 71 includes a telescopic frame 712, and the two ends of the telescopic frame 712 are respectively a translation end and an adjustment end. The two sides of the adjustment end are respectively connected to the tail frame 44 through a connecting seat 715 and an electric push rod 711. The axial direction of the electric push rod 711 is parallel to the axial direction of the first roller 41. By moving the output end of the electric push rod 711, the distance between it and the connecting seat 715 is adjusted, thereby driving the telescopic frame 712 to deform, changing the position of the translation end, and realizing the position translation of the telescopic unit; the two sides of the translation end are respectively connected with a connecting seat 715 and a slider 713, and the slider 713 is slidably connected with a slide rail 714. The slide rail 714 and the above-mentioned connecting seat 715 are fixed on a translation plate 716 to drive the translation plate 716 to move along a direction parallel to the length of the track 5.

[0053] The length direction of the translation plate 716 is parallel to the axial direction of the first roller 41, and the two telescopic units are respectively arranged at the two ends of the translation plate 716 away from the telescopic frame 712. In the telescopic unit, the axial direction of the insertion rod 721 is parallel to the axial direction of the first roller 41 and the outer sliding sleeve of the insertion rod 721 is provided with a ring 726, the ring 726, the ring 726 and the electromagnet 724 are all fixed on the translation plate 716, and the elastic member 723 is a compression spring connected between the electromagnet 724 and the magnetic attraction plate 722.

[0054] After adopting the above structure, by turning on and off the power of the electromagnet 724, changing the magnetic field strength and direction of the electromagnet 724, the force between the magnetic plate 722 and the electromagnet 724 can be changed, and the elastic member 723 is cooperated to make the magnetic plate 722 and the plug rod 721 move axially along the collar 726, and change the axial position of the plug rod 721, so that the end of the plug rod 721 away from the magnetic plate 722 is inserted into the socket 611 or leaves the socket 611, thereby realizing the detachable connection between the push-pull assembly 7 and the transfer rack 6. The docking member 61 is provided with a plurality of sockets 611 spaced apart along the length direction of the track 5, and the plug rod 721 can dock with any of the sockets 611, thereby facilitating the connection between the push-pull assembly 7 and the transfer rack 6.

[0055] A further improvement is that a ball 725 is protruded from one end of the insertion rod 721 away from the electromagnet 724 , and the ball 725 rotates on the insertion rod 721 around its own spherical center.

[0056] By setting the ball bearing 725, when the insertion rod 721 moves toward the docking piece 61 and is not inserted into the socket 611, after the ball bearing 725 abuts against the docking piece 61, when the translation unit 71 drives the telescopic unit to move, the position of the telescopic unit is changed, and the ball bearing 725 is used to reduce the friction between the insertion rod 721 and the docking piece 61. In this way, as the telescopic unit translates, the end of the insertion rod 721 away from the magnetic suction plate 722 can be inserted into one of the sockets 611, thereby realizing the connection between the push-pull assembly 7 and the transfer frame 6.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
