Description

Technical Field

[0001] This utility model relates to the field of length setting and cutting technology for automotive suspension springs, specifically to a length setting forming and cutting device for automotive suspension springs. Background Technology

[0002] The spring strength requirements for automotive suspension springs are higher than those for conventional springs, and the requirements for their manufacturing process are also more stringent. The need for fixed-length and timed cutting requires the use of multiple sets of motors and cylinders for electrical control, resulting in greater energy loss and waste of industrial electricity.

[0003] Existing methods for manufacturing and cutting automotive suspension springs require multiple sets of motors and cylinders, which is resource-intensive. For example, CN215238611U discloses a cutting device for automotive suspension spring production, comprising a body, a working chamber, and a base. The working chamber is located at the lower end of the body, and an electric telescopic rod is installed on the center left side of the working chamber. A baffle plate is fixedly connected to the right end of the electric telescopic rod. This invention uses a laser cutter to produce a smoother cut that is less prone to cracking. By installing a fixed plate, the spring to be cut can be placed in the fixed plate and fixed therein by a locking block engaging with a locking slot. The bottom of a threaded block engages with the top of a threaded rod. When a second motor drives the threaded rod to rotate, the locking block pushes the spring to move until it reaches the baffle plate. The position of the baffle plate can be adjusted by installing an electric telescopic rod, thus controlling the length of the spring to be cut. A placement box is installed at the bottom of the baffle plate, where the spring will fall after cutting for easy collection. However, this solution cannot achieve timed, scheduled cutting of suspension springs.

[0004] Therefore, it is necessary to invent a fixed-length forming and cutting device for automotive suspension springs to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fixed-length forming and cutting device for automotive suspension springs, in order to solve the problem that the timing and length cutting of suspension springs in the present invention requires multiple motors and cylinders, which wastes resources.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length forming and cutting device for automotive suspension springs, comprising a main body, a protective cover, a feeding port, a feeding mechanism, a cutter, and a cutting table. The protective cover is fixedly connected to the main body, and an inclined feeding port is fixedly provided at the bottom of the protective cover. The protective cover is T-shaped and has a viewing window and a dustproof net. A feeding mechanism is provided between the protective cover and the main body. The feeding mechanism consists of multiple sets of rollers of the same diameter, and the surfaces of the multiple sets of rollers are clamped to the steel reinforcement material used for the suspension springs. Two pushing mechanisms are arranged in a mirror image on the main body. The output end of one pushing mechanism is a U-shaped component, and the output end of the other pushing mechanism is a roller. Both pushing mechanisms are inclined. A hydraulic cylinder is also provided on the main body, and the output end of the hydraulic cylinder is connected to a cutter. The bottom of the cutter can contact the cutting table, which is fixedly connected to the main body. A movable fixed-length auxiliary component is also provided on the main body, extending beyond the main body and contacting the surface of the supplied steel reinforcement material used for the suspension springs.

[0007] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0008] This invention uses dual motors to power the feeding mechanism, continuously conveying the steel used for suspension springs. Simultaneously, it drives a bevel gear set and a cam, causing the fixed-length auxiliary component to move back and forth, moving the spring laterally to the same length where it is cut by the cutter. The entire process achieves fixed-length, timed cutting of the suspension spring. Furthermore, the invention utilizes a rolling mechanism adapted to the groove on the cam to drive the connecting rod to slide within a slot. When the fixed-length auxiliary component is pushed to its maximum limit, the connecting rod slides upwards to its highest point, pressing against the pushing component and opening the hydraulic cylinder. This activates the cutter to cut the material. The entire process requires only dual motors, eliminating the need for additional power sources and saving energy. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figures 1-3 The illustrated device for cutting and shaping automotive suspension springs to a fixed length includes a main body 1, a protective cover 2, a feeding port 3, a feeding mechanism 4, a cutter 7, and a cutting table 8. The protective cover 2 is fixedly connected to the main body 1. An inclined feeding port 3 is fixedly provided at the bottom of the protective cover 2. The protective cover 2 is T-shaped and has a viewing window and a dustproof net. A feeding mechanism 4 is provided between the protective cover 2 and the main body 1. The feeding mechanism 4 consists of multiple sets of rollers of the same diameter, and the surfaces of these rollers are clamped to the suspension springs using reinforcing steel. The main body 1... The equipment is configured with two push mechanisms 5 in a relatively mirror-like arrangement. The output end of one push mechanism 5 is a U-shaped part, and the output end of the other push mechanism 5 is a roller. Both push mechanisms 5 are inclined. The main body 1 is also equipped with a hydraulic cylinder 6. The output end of the hydraulic cylinder 6 is connected to a cutter 7. The bottom of the cutter 7 can contact the cutting table 8. The cutting table 8 is fixedly connected to the main body 1. The main body 1 is also equipped with a movable fixed-length auxiliary part 9. The fixed-length auxiliary part 9 extends out of the main body 1 and can contact the surface of the steel reinforcement material of the suspension spring that is delivered.

[0018] This allows the entire main body 1 to be transported to the front of the cutting table 8, rotated by two sets of pushing mechanisms 5, and extended laterally by the fixed-length auxiliary parts 9. After reaching a certain length, it is cut by the cutter 7 and the cutting table 8.

[0019] The fixed-length auxiliary component 9 extends into the inner end of the equipment body 1 and is connected to a connecting rod 10. The top end of the connecting rod 10 is slidably connected in a slide groove 101. The slide groove 101 is opened on the back of the equipment body 1. The top of the slide groove 101 is connected to a pusher 11 by a spring. The pusher 11 can contact the electric control switch 601. The electric control switch 601 is electrically connected to the hydraulic cylinder 6. The connecting rod 10 is hinged to the end of the fixed-length auxiliary component 9 extending into the equipment body 1. The length of the connecting rod 10 is close to the length of the slide groove 101.

[0020] When the fixed-length auxiliary component 9 is pushed forward to its limit, the connecting rod 10 is pushed upward to its highest point, pressing against the pusher 11 at the top of the slide 101, opening the electric control switch 601, and activating the hydraulic cylinder 6 to push the cutter 7 to cut the material.

[0021] The feeding mechanism 4 is driven to rotate by two motors 12 and two sprockets 13. A bevel gear set 14 is installed on the two sprockets 13, and a cam 15 is connected to the bevel gear set 14. A groove is opened on the surface of the cam 15. The groove is adapted to the thickness of the roller at the end of the fixed length auxiliary part 9 that extends into the inner end of the equipment body 1. The two sprockets 13 are arranged in parallel, and the rotation frequency of the two sprockets 13 is the same.

[0022] The continuous feeding of the feeding mechanism 4 is powered by the dual motors 12 and the dual sprockets 13. The continuous rotation of the dual sprockets 13 also provides timing control for the start hydraulic cylinder 6, thereby realizing the timing of material cutting.

[0023] Working principle of this utility model:

[0024] Refer to the instruction manual appendix Figures 1-3 When using this utility model, the raw material steel or steel bar of the suspension spring is first transported to the feeding mechanism 4 through a reel. The continuously rotating feeding mechanism 4 transports it into the protective cover 2. When it is close to the cutting table 8, the two pushing mechanisms 5 are activated to continuously wind the end of the steel bar upward into a spring shape.

[0025] The synchronous fixed-length auxiliary component 9 will also continuously move outward from the main body 1 of the equipment, extending laterally while continuously winding upward, supporting the suspension spring of a certain length.

[0026] Refer to the instruction manual appendix Figures 3-5 When using this utility model, the operation of the dual motors 12 drives the feeding mechanism 4, which in turn drives the dual sprockets 13, which in turn drives the bevel gear set 14 to rotate, causing the cam 15 to rotate. The rotation of the cam 15 causes the fixed-length auxiliary part 9 to continuously extend and reciprocate on the main body 1 of the equipment, so that the suspension spring is continuously pushed laterally until it is cut off after reaching a certain length, and then returns to the initial position. When the fixed-length auxiliary part 9 is extended to the limit length, the connecting rod 10 is raised to the maximum height, which presses the pusher 11 to press the electric control switch 601, which starts the hydraulic cylinder 6 to push the cutter 7, and cuts off the suspension spring.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
