Description

Technical Field

[0001] This utility model relates to the field of bearing forging heating technology, and in particular to the structure of bearing forging heating furnace. Background Technology

[0002] Heating is crucial in bearing forging. When heating bearings for forging, a medium-frequency induction forging furnace is used. In this furnace, the bearing blank is fed into the furnace by a feeding structure. By passing a medium-frequency alternating current through the induction coil, an alternating magnetic field is generated. Due to electromagnetic induction, eddy currents are generated inside the bearing blank within the magnetic field. The blank's own resistance generates heat according to Joule's law as the eddy currents pass through, achieving direct internal heating and rapidly raising the temperature to the required forging temperature. The heated bearing blank is then sent out for forging.

[0003] In existing bearing forging furnaces, the bearing billet is fed into the furnace by an external conveying structure and supported by a bracket. As the billet is continuously pushed, it can move across the surface of the bracket and pass through the furnace to complete the heating process. However, the size of this bracket is usually fixed, and different sizes of brackets are usually required for bearing billet bars of different sizes. The replacement of the entire bracket is quite cumbersome, which makes bearing forging heating inconvenient. Therefore, we propose a bearing forging furnace structure. Utility Model Content

[0004] The main purpose of this utility model is to provide a bearing forging heating furnace structure. By setting a support mechanism at the base where the heating furnace body is located, the support mechanism adopts a V-shaped row of seats and a C-shaped support bar to form a liftable material support structure, which can support bearing blanks of different diameters. Unlike the traditional method, it does not require frequent replacement of different sized supports, thus meeting the heating requirements of bearing blanks of different sizes, improving the versatility and ease of use of the heating furnace, and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The bearing forging heating furnace structure includes a heating furnace body and a base. The heating furnace body is mounted on the surface of the base and also includes a support mechanism. The support mechanism includes an L-shaped support, a fixed block, a V-shaped support, a C-shaped support bar, a guide plate, a pallet box, a sliding rod, and an electric push rod. L-shaped supports are symmetrically installed on the base surfaces on both sides of the heating furnace body, and a fixed block is inserted into the top of the L-shaped support. The fixed block is symmetrically fixed in the V-shaped support, and the seat of the V-shaped support protrudes into the furnace chamber of the heating furnace body. A middle limit groove for mounting the C-shaped support bar is opened through the bottom plate of the V-shaped support. A guide plate is symmetrically fixed at the lower part of the C-shaped support bar that protrudes from the heating furnace body. The guide plate is locked in the pallet box by bolts and nuts. A sliding rod is welded to one side of the pallet box. The rod of the sliding rod protrudes through the sliding groove opened on the surface of the L-shaped support and is installed with the telescopic rod head of the electric push rod.

[0007] Furthermore, the top of the L-shaped support body is provided with a fixed groove, and a fixed block is vertically engaged in the fixed groove;

[0008] By adopting the above technical solution, the L-shaped support can be used to clamp the fixed block in the fixed groove, thereby providing support.

[0009] Furthermore, the vertical body of the L-shaped support has a sliding groove on its surface, and a base plate is welded to the bottom of the vertical body of the L-shaped support. An installation hole for screwing bolts is provided between the base plate and the base of the L-shaped support.

[0010] By adopting the above technical solution, the base plate of the L-shaped support can be locked to the base surface with bolts, and the vertical body of the L-shaped support has a groove for the sliding rod to slide.

[0011] Furthermore, the V-shaped seat wall surface of the V-shaped seat is symmetrically provided with grooves, and the inner seat wall at both ends of the V-shaped seat is provided with arc-shaped surfaces.

[0012] By adopting the above technical solution, the grooves of the V-shaped bearing seat facilitate the entry of heat to heat the bearing blank, while the V-shaped bearing seat can support the bearing blank with its arc-shaped surface.

[0013] Furthermore, the surface of the C-shaped support strip is provided with a concave arc-shaped surface, and the guide plate below the C-shaped support strip is inserted downward into the upper cavity of the tray box. The guide plate and the surface of the tray box are provided with through holes for bolts to pass through and screw on with nuts.

[0014] By adopting the above technical solution, the C-shaped support bar can support the bearing blank with its arc surface. Then, the guide plate below the C-shaped support bar is inserted into the cavity of the tray box. Bolts are used to pass through the through holes of the guide plate and the tray box and screw them with nuts to lock the connection between the guide plate and the tray box.

[0015] Furthermore, the telescopic rod head of the electric actuator is welded with a disc body with a U-shaped clamp fixed at the top, and the U-shaped clamp and the slide rod surface are provided with through holes for bolts to pass through and screw on with nuts.

[0016] By adopting the above technical solution, after welding a U-shaped chuck to the disc of the electric actuator, a slide rod is installed inside the U-shaped chuck, and then the bolt passes through the through hole of the U-shaped chuck and the slide rod and is locked with the nut.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a support mechanism at the base where the heating furnace body is located. The support mechanism consists of a V-shaped row of seats and a C-shaped support bar to form a liftable material support structure, which can support bearing blanks of different diameters. Unlike the traditional method, it does not require frequent replacement of different sized supports, thus meeting the heating requirements of bearing blanks of different sizes and improving the versatility and ease of use of the heating furnace.

[0019] Furthermore, the installation and adjustment of the support mechanism are relatively simple. The slide bar is raised and lowered in the slide groove by the electric push rod, which in turn drives the C-shaped support bar to rise or fall. The operation process can be controlled as needed by connecting an external controller under the guidance of professional electrical technicians, which makes it convenient to control the C-shaped support bar to support the bearing blank in the V-shaped seat for heating.

The fixed blocks 6 are symmetrically fixed within the V-shaped support 7. The seat of the V-shaped support 7 extends through the furnace chamber of the heating furnace body 1. The bottom plate of the V-shaped support 7 has a central limiting groove 8 for mounting the C-shaped support strip 9. The C-shaped support strip 9 extends through the lower strip of the heating furnace body 1 and is symmetrically fixed with guide plates 10. The guide plates 10 are locked in the tray box 11 by bolts and nuts. A sliding rod 12 is welded to one side of the tray box 11. The rod of the sliding rod 12 extends through the sliding groove 13 opened on the surface of the L-shaped support 4 and is installed with the telescopic rod head of the electric push rod 14.

[0026] The L-shaped support 4 has a fixed groove 5 at the top of its base, and a fixed block 6 is vertically fitted into the fixed groove 5.

[0027] By adopting the above technical solution, the L-shaped support 4 can be fitted with the fixed block 6 through the fixed groove 5, thereby providing support.

[0028] The vertical body of the L-shaped support 4 has a sliding groove 13 on its surface, and a base plate is welded to the bottom of the vertical body of the L-shaped support 4. An installation hole for screwing bolts is provided between the base plate of the L-shaped support 4 and the base 2.

[0029] By adopting the above technical solution, the base plate of the L-shaped support 4 can be locked to the surface of the base 2 with bolts, and the slide rod 12 can slide through the groove 13 at the vertical base of the L-shaped support 4.

[0030] The V-shaped seat 7 has symmetrically arranged grooves on its V-shaped seat wall surface, and arc-shaped surfaces are provided at both ends of the inner seat wall of the V-shaped seat 7.

[0031] By adopting the above technical solution, the groove of the V-shaped seat 7 facilitates the entry of heat to heat the bearing blank, and the V-shaped seat 7 can support the bearing blank with its arc-shaped surface.

[0032] The C-shaped support strip 9 has a concave arc surface on its surface, and the guide plate 10 below the C-shaped support strip 9 is inserted downward into the upper cavity of the tray box 11. The guide plate 10 and the tray box 11 have through holes for bolts to pass through and screw on.

[0033] By adopting the above technical solution, the C-shaped support bar 9 can support the bearing blank with its arc surface. Then, the guide plate 10 below the C-shaped support bar 9 is inserted into the cavity of the tray box 11. Bolts are used to pass through the through holes of the guide plate 10 and the tray box 11 and screwed into the nuts to lock the guide plate 10 and the tray box 11.

[0034] The electric actuator 14 has a plate body with a top-fixed U-shaped clamp 15 welded to the telescopic rod head, and the U-shaped clamp 15 and the slide rod 12 have through holes for bolts to pass through and screw on.

[0035] By adopting the above technical solution, after the U-shaped chuck 15 is welded to the disc body of the electric actuator 14, the slide rod 12 is inserted inside the U-shaped chuck 15, and then the bolt passes through the through hole of the U-shaped chuck 15 and the slide rod 12 and is locked with the nut.

[0036] It should be noted that this utility model is a bearing forging heating furnace structure. A support mechanism 3 is set at the base 2 where the heating furnace body 1 is located. The slide rod 12 of the support mechanism 3 passes through the slide groove 13 of the L-shaped support 4. Then, the L-shaped support 4 can be symmetrically installed on the surface of the base 2 on both sides of the heating furnace body 1 with the help of bolts. The C-shaped support strip 9 is pressed into the middle limit groove 8 of the V-shaped support 7. Then, the V-shaped support 7 can pass through the furnace chamber of the heating furnace body 1. At the same time, the V-shaped support 7 is positioned and locked in the fixed groove 5 by the fixing block 6 below. Then the C-shaped support 9 is installed in the middle limit groove 8 of the V-shaped support 7.

The liftable support structure formed by the V-shaped seat 7 and the C-shaped support bar 9 can support bearing blanks of different diameters. Subsequently, the bearing blank conveying machinery can directly feed the bearing blank onto the surface of the C-shaped support bar 9, and then the V-shaped surface of the V-shaped seat 7 can cooperate with the bearing blank to limit its movement. With continuous feeding, the bearing blank can be heated before forging within the heating furnace body 1. After heating, the bearing blank can be discharged from the V-shaped support 7 and sent to the bearing forging equipment for forging. The V-shaped support 7 can support and heat bearing blanks of multiple diameters. At the same time, the internal angle of the V-shaped support 7 can be customized as needed, so that the heating furnace body 1 can use the cooperation of the V-shaped support 7 and the C-shaped support strip 9 to support and heat bearing blanks of multiple diameters within the heating furnace body 1 before forging.
