Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a cutting device for processing metal spring materials. Background Technique

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original shape after the external force is removed, also known as a "spring". Generally made of spring steel, the types of springs are complex and diverse. According to the shape, there are mainly helical springs, scroll springs, leaf springs, special-shaped springs, etc. After the spring is processed, there will be a part of the metal rod remaining at both ends, and this part of the metal rod needs to be cut off. Therefore, a cutting device for processing metal spring materials is required for the cutting operation.

[0003] After retrieval, the Chinese patent publication number CN216632865U discloses a material cutting device for metal spring processing, including a bottom main body. Adjusting devices are installed inside both vertical plates. Fixed cutting devices are installed on the opposite sides of the two vertical plates. A threaded rod is movably connected inside the chute. The right side of the threaded rod is fixedly connected to a turntable. An adjusting disk is fixedly connected to the outside of the sleeve rod. A stop block is arranged on the outside of the sleeve rod. A spring is sleeved on the outside of the sleeve rod. In the utility model, when the cutting knife cuts off the redundant part, the top fixed block and the bottom fixed block just come into contact with each other, and the redundant part is located between the top fixed groove and the bottom fixed groove, and the redundant part will not fly out when it is cut off.

[0004] However, there are certain defects in actual use. After the spring is cut off, the redundant part will remain inside the fixed groove. Therefore, after each cutting operation on the spring, the redundant part needs to be cleaned and collected, which affects the processing efficiency. Summary of the Utility Model

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , an embodiment provided by the present utility model: A cutting device for processing metal spring materials, including a bottom plate 1 for assembling the cutting device. The middle of the bottom plate 1 is provided with a base 2 by screws or welding. The first electric push rods 5 of the pressing assembly are equidistantly arranged on the base 2 (at the four corners). The output ends (i.e., the tops) of the first electric push rods 5 are jointly installed with a moving pressure plate 6. Arc-shaped grooves are opened on both the lower side of the moving pressure plate 6 and the upper side of the base 2, and rubber pads 7 are bonded in the arc-shaped grooves, which can facilitate the preliminary positioning and fixing of the spring body 4 to be cut, and then facilitate the subsequent cutting operation on the redundant parts at both ends of the produced spring body 4. For the convenience of the cutting operation, the hydraulic telescopic rods 8 of the lifting assembly in the cutting mechanism are symmetrically arranged along the center at both ends of the base 2. The output ends of the hydraulic telescopic rods 8 are fixedly installed with a lifting plate 9. The bottom end of the lifting plate 9 is welded with a mounting plate 11. The mounting plate 11 can be fixedly installed with a cutting knife 12 by bolts, which is convenient for the cutting operation and also convenient for disassembly for maintenance or replacement operations.

[0024] Please refer to Figures 1 - 5 , and in order to conveniently lift and position both ends of the spring body 4 during truncation, and at the same time, it is also convenient to automatically collect the truncated materials after truncation to avoid jamming. At the same time, it is also possible to select to truncate both ends simultaneously according to the situation of the spring body 4. For those that do not meet the requirements, one end can be truncated first, and then the other end can be truncated. Collection hoppers 3 are symmetrically arranged along the center at both ends of the base 2 to facilitate the collection of the truncated metal materials, and thus it is convenient for subsequent recycling and reuse. Electric push rods two 10 of the lifting mechanism (fixedly installed on the bottom plate 1) are symmetrically arranged along the center at both ends of the base 2. The output end of the electric push rod two 10 is fixedly installed with an adjusting plate 13. In the middle of the top end of the adjusting plate 13, a rectangular plate 14 can be fixedly installed through screws. In the middle of the rectangular plate 14, a rotating block 15 of the rotating assembly is welded. The rotating end of the rotating block 15 is connected with a connecting plate 16. The connecting plate 16 is fixedly welded with the supporting plate 18, which can conveniently drive the supporting plate 18 to rotate on the rotating block 15. Two groups of positioning members 17 are welded at the rear end of the supporting plate 18. A clamping groove is opened at the bottom end of the positioning member 17 (as shown in Figure 5 ), which can be used for limiting when the supporting plate 18 is horizontal to avoid rotation. A placing groove 19 for conveniently placing the part of the spring body 4 to be truncated is opened on the supporting plate 18, and a truncating groove 20 for conveniently performing the truncating operation is also opened, which is convenient for cooperating with the truncating knife 12 to perform the truncating operation.

[0025] Working principle: When the present utility model is in use, the spring body 4 to be truncated is placed in the arc-shaped groove of the base 2. By the contraction of the electric push rod one 5, the moving pressure plate 6 is driven to move downward, and then it contacts with the spring body 4. Cooperating with the rubber pad 7, the spring body 4 can be initially positioned and fixed. Then, by the elongation of the electric push rod two 10, the adjusting plate 13 and the rectangular plate 14 are driven to move upward. At this time, due to the action of the rotating block 15 and the connecting plate 16, the supporting plate 18 is in an inclined state (one end located in the collection hopper 3 is low and the rear end is high), and the high rear end contacts with the spring body 4 to be truncated. As it continues to move upward, the supporting plate 18 and the connecting plate 16 can be driven to rotate on the rotating block 15 until it is horizontal. When it rotates to the horizontal position, the positioning member 17 is engaged with the rectangular plate 14 for limiting, which can prevent further rotation and ensure the horizontal state during truncation. At this time, the spring body 4 to be truncated enters the placing groove 19. By the downward movement of the hydraulic telescopic rod 8, the lifting plate 9 is driven to move downward, and then the truncating knife 12 contacts with it. Cooperating with the truncating groove 20, the truncating operation can be completed. Then, the hydraulic telescopic rod 8 moves upward to reset, and at the same time, the electric push rod two 10 contracts, driving the adjusting plate 13 to move downward. Under the action of its own gravity, the supporting plate 18 starts to rotate and incline, and then inclines towards the direction of the collection hopper 3, so that the truncated metal materials can enter the collection hopper 3 along the placing groove 19. Then, the electric push rod one 5 elongates to drive the moving pressure plate 6 to move upward to reset, and the pressing on the spring body 4 is lost, and it can be taken off, which is convenient for the next truncating use.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
