[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the present utility model discloses an induction heating automatic feeding device for seamless bearing steel pipes.

[0026] Embodiment 1

[0027] The present utility model provides an induction heating automatic feeding device for seamless bearing steel pipes as shown in Figures 1-3 Figure 34, which includes a feeding hopper 1 and an open-ended hollow plate 2 communicated with the top of the feeding hopper 1. A support frame 3 is fixedly arranged at the bottom of the open-ended hollow plate 2. A connecting frame 4 is fixedly arranged on the side wall of the open-ended hollow plate 2, and a heating pipe 5 is fixedly arranged through the connecting frame 4. An induction coil 6 is wound around the outside of the heating pipe 5;

[0028] An outlet hole is opened at the lower end of the side of the open-ended hollow plate 2 close to the heating pipe 5. A guide groove is opened at the bottom of the open-ended hollow plate 2. A slider 7 is slidably penetrated in the guide groove. A groove is opened at the top of the slider 7, and a push plate 8 is arranged in the groove. A pushing mechanism for driving the push plate 8 to move is arranged between the slider 7 and the support frame 3. A blanking slope 16 is opened at the lower side of the inner wall of the open-ended hollow plate 2, and a storage groove 17 is opened, and the storage groove 17 is communicated with the guide groove;

[0029] A through hole is opened inside the push plate 8. A guide plate 11 is slidably penetrated through the inner wall of the through hole. The guide plate 11 is fixedly arranged in the groove. A first spring 12 is arranged in the through hole. Two ends of the first spring 12 are respectively fixedly connected with the guide plate 11 and the top of the inner wall of the through hole.

[0030] Before the steel pipe is induction heated, multiple seamless bearing steel pipes are placed in the feeding hopper 1. At this time, under the internal space limitation of the open hollow plate 2, multiple steel pipes are vertically arranged in the open hollow plate 2. Then the slider 7 drives the push plate 8 to move horizontally, so that the push plate 8 moves out of the receiving groove 17 and pushes the end of the steel pipe, so that the steel pipe can enter the heating pipe 5 through the feeding hole for heating. When the push plate 8 moves back, supported by the inclined surface of the push plate 8 and the elastic force of the first spring 12, the push plate 8 can be supported by the lowest steel pipe and enter the groove, and rebound into the receiving groove 17 when moving to the other end of the steel pipe, so as to facilitate the subsequent pushing and feeding of the steel pipe.

[0031] Example 2

[0032] Example 2 is based on Example 1 in order to enable the slider 7 to drive the push plate 8 to move back and forth to complete the pushing of the steel pipe. Figures 1-2 As shown, the pushing mechanism includes a motor 9, which is fixed to the upper end of the outer wall of the support frame 3, and the output shaft passes through the support frame 3 and is fixed with a reciprocating screw 10, and the slider 7 is threadedly sleeved on the outside of the reciprocating screw 10.

[0033] Before the steel pipe is processed, the motor 9 is started to rotate the reciprocating screw 10. At this time, the reciprocating screw 10 pushes the slider 7, so that the slider 7 moves stably laterally in cooperation with the guide groove. At the same time, after the push plate 8 pushes the steel pipe into the heating pipe 5, it can be stably moved back to its original position, ensuring that the feeding work of the steel pipe is carried out continuously and stably.

[0034] Example 3

[0035] Example 3 is based on Example 1 to avoid as much as possible that when the steel pipe inside the heating pipe 5 is heated, the heat inside the heating pipe 5 is not transferred outwards and affects the steel pipe inside the open hollow plate 2. Figure 1 As shown, a vertical rod 13 is slidably provided on the top of the connecting frame 4, and an insulating block 14 is fixedly provided on the bottom of the vertical rod 13. The insulating block 14 and the push plate 8 are provided with a pushing slope on the side close to the support frame 3. The insulating block 14 is arranged between the heating tube 5 and the open hollow plate 2. The lower end of the vertical rod 13 is provided with a second spring 15, and the two ends of the second spring 15 are fixedly connected to the connecting frame 4 and the insulating block 14 respectively.

[0036] By setting the heat-insulating block 14, the end of the heating tube 5 close to the open hollow plate 2 can be blocked, so as to avoid the heat inside the heating tube 5 from being transferred outward and affecting the steel tube inside the open hollow plate 2. At the same time, under the setting of the vertical rod 13 and the second spring 15, when the steel tube moves laterally and is pushed, the heat-insulating block 14 can be moved longitudinally and returned to its original position by pushing the inclined surface, so as not to hinder the unloading work of the steel tube and ensure the use effect of the device.

[0037] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
