DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 4 As shown, a material return structure proposed in one embodiment of the present application includes:

[0026] A sliding frame 1 is slidably arranged on the frame, the sliding frame 1 is in a vertical direction and slides in the vertical direction, and a ring plate 2 is arranged on the sliding frame 1 and sleeved on the outer side of the cylinder, and the ring plate 2 is in a horizontal direction and fixed on the sliding frame 1;

[0027] A driving member is arranged on the frame and the sliding frame 1, and drives the sliding frame 1 to slide through the driving member;

[0028] The unloading chute 3 and the pushing piece are both arranged on the frame. The unloading chute 3 is fixed on the frame. The unloading chute 3 includes a flat plate and an inclined plate that are fixedly connected. The workpiece on the ring plate 2 is pushed onto the unloading chute 3 by the pushing piece.

[0029] In the initial state, the ring plate 2 is close to the bottom of the cylinder, the two molds are far away from the cylinder, and the movable ends of the two hydraulic cylinders are retracted. When in use, the staff will place the workpiece horizontally on the frame, so that the movable end of one of the hydraulic cylinders will be extended first and then retracted, driving the corresponding mold to slide, and the workpiece is extruded into a U-shape through the cooperation of the mold and the cylinder, and then the movable end of the other hydraulic cylinder will be extended first and then retracted, driving the corresponding mold to slide, and the workpiece is extruded into a circular ring through the cooperation of the mold and the cylinder, and then the sliding frame 1 is driven by the driving member to slide upward, driving the ring plate 2 to move away from the cylinder, and the circular ring workpiece is removed from the cylinder through the ring plate 2, and then the workpiece on the ring plate 2 is pushed to the unloading slide 3 by the pushing member. The workpiece is first located on the flat plate, and then slides down along the inclined plate, and then the sliding frame 1 is driven by the driving member to slide downward, driving the ring plate 2 to move to the initial position;

[0030] To sum up, the present application abandons the method in the prior art in which the staff removes the annular workpiece from the cylinder. When in use, the sliding frame 1 is driven to slide by the driving member, driving the ring plate 2 to move together, and the annular workpiece is removed from the cylinder through the ring plate 2, and then the workpiece on the ring plate 2 is pushed into the unloading chute 3 by the pushing member, and the material is unloaded through the unloading chute 3, which avoids the annular workpiece from being difficult to remove due to its close fit to the cylinder. The operation is convenient, and at the same time, it avoids the hand being pinched by the mold due to machine failure, reduces safety hazards, and is therefore more practical.

[0031] like Figure 4 As shown, in some embodiments, the driving member includes a roller 4 rotatably arranged on a sliding frame 1, the roller 4 is in a vertical direction, a slide plate 5 is slidably arranged on the frame, the slide plate 5 is in a horizontal direction and slides in the horizontal direction, and a first plane 6, a guide inclined plane 7 and a second plane 8 are continuously distributed on the slide plate 5, the first plane 6 and the second plane 8 are both in a horizontal direction and have a height difference, the guide inclined plane 7 is used to connect the first plane 6 and the second plane 8, and the roller 4 rolls and overlaps with the first plane 6, the guide inclined plane 7 and the second plane 8;

[0032] Referring to the above, in the initial state, the skateboard 5 is located at the initial position, the roller 4 rolls and overlaps with the first plane 6, and the ring plate 2 is located at the initial position. When in use, the skateboard 5 is driven to slide forward, and the roller 4 first rolls from the first plane 6 to the guide slope 7, and then rolls from the guide slope 7 to the second plane 8. During this process, the roller 4 moves upward and drives the sliding frame 1 to slide upward. Conversely, the skateboard 5 is driven to slide in the opposite direction to the initial position, and the sliding frame 1 will slide downward due to gravity. The roller 4 first rolls from the second plane 8 to the guide slope 7, and then rolls from the guide slope 7 to the first plane 6.

[0033] like Figure 4As shown, in some embodiments, a compression spring 9 is provided between the sliding frame 1 and the frame, and the compression spring 9 is in a vertical direction and has two ends fixedly connected to the sliding frame 1 and the frame respectively;

[0034] Referring to the above, in the initial state, the extrusion spring 9 is in a natural state. When the sliding frame 1 slides upward, the extrusion spring 9 is forced to be squeezed. When the sliding frame 1 slides downward due to gravity, the extrusion spring 9 returns to the natural state. Through the design of the extrusion spring 9, interference and jamming can be avoided when the sliding frame 1 slides downward, making the sliding of the sliding frame 1 smoother.

At this time, the mold and the resistance block 10 are in contact and overlapped, the elastic member is in a natural state, and the slide plate 5 is in the initial position. When in use, the mold is slid from the initial position to the extreme position, driving the resistance block 10 to slide together, and the slide plate 5 is driven to slide forward through the transmission member, and the elastic member is squeezed. Conversely, when the mold slides from the extreme position to the initial position, the elastic member is reset to the natural state, and the elastic potential energy is used to drive the resistance block 10 and the slide plate 5 to slide to the initial position together. This design not only improves the synchronization during use, but also does not require additional power, and is more convenient to use.

Conversely, when the elastic member is restored to the natural state, the slide plate 5 applies tension to the pull rope 14, and the pull rope 14 is guided and limited by the guide wheel 12 and the two fixed pulleys 13, and the resistance block 10 is pulled by the pull rope 14 to slide to the initial position.

Conversely, when the mold slides from the extreme position to the initial position, the return spring 18 returns to the natural state, and drives the slide plate 5 to slide to the initial position through elastic potential energy, driving the slide bar 16 and the limit block 17 to move to the initial position together.

[0041] like Figure 1 As shown, in some embodiments, the pusher includes an electric push rod 19 arranged on the frame, the electric push rod 19 is horizontal and fixed on the frame, and the movable end of the electric push rod 19 is provided with an arc plate 20 that contacts and overlaps with the workpiece, and the arc plate 20 is horizontal and fixedly connected to the movable end of the electric push rod 19;

[0042] Referring to the above, in the initial state, the movable end of the electric push rod 19 is retracted, and the arc plate 20 is close to the electric push rod 19.
