Description

Technical Field

[0001] The present application relates to the field of spring manufacturing, and more particularly, to a cutting device for a hanger spring. Background Art

[0002] A spring is an elastic element that works by generating large elastic deformations on its own. It is widely used in various types of machines. There are many types of springs. According to the nature of the load they bear, springs are mainly divided into four types: tension springs, compression springs, torsion springs, and bending springs. However, in some special occasions, a cutting device for a certain type of spring is required to meet the needs of installation or assembly. When the wire diameter of some springs is relatively large, it often brings quite a lot of trouble to the cutting of the wire. Sometimes, it is even necessary to stop the entire machine and let another machine or tooling come in to cut the wire, which makes the entire spring processing discontinuous, reduces the processing efficiency, and increases the processing cost of a single spring.

[0003] The patent document with the publication number CN207358023U discloses a cutting device for a spring, which includes a blocking mechanism, a cutting table mechanism, and a cutting tool mechanism. The blocking mechanism is used to prevent the spring processing device from stopping working. The cutting table mechanism includes a cutting table and a traveling device. The cutting table extends into the interior of the spring and abuts against the wire of the spring. The traveling device is used to control the cutting table to extend into the interior of the spring and retract the cutting table when the cutting tool mechanism cuts the wire of the spring. The cutting tool mechanism includes a cutting tool and a propulsion device. When the cutting table abuts against the wire of the spring, the cutting tool is tangent to the cutting table to cut the wire of the spring. The propulsion device propels the cutting tool to cut the wire of the spring and drives the cutting tool to retract to its original position when it is tangent to the cutting table. This cutting device can cut springs with a relatively large wire diameter, which is beneficial to the continuous operation of the spring processing device, improves efficiency, and reduces costs. Although the above application document can facilitate the continuous operation of the spring processing device, improve efficiency, and reduce costs, the spring is not fixed during cutting, and it is easy to deviate during cutting, resulting in low cutting accuracy. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the present utility model provides a cutting device for a hanger spring, which solves the problems raised in the above-mentioned background art. To achieve the above objectives, the present utility model is realized through the following technical solutions: A cutting device for a hanger spring, comprising a box body, on which a clamping device is provided. The clamping device includes a fixed seat, which is fixedly connected to the bottom of the inner wall of the box body. A chute is provided at the top of the fixed seat, and a slider is slidably connected to the bottom of the inner wall of the chute. A clamping block is fixedly connected to the top of the slider. The top of the fixed seat is rotatably connected to a rotating rod through a bearing. A rotating block is fixedly connected to the top of the rotating rod, and a movable rod is hinged to the top of the rotating block.

[0005] Preferably, the left side of the movable rod is hinged to the bottom of the inner wall of the clamping block, and a bracket is fixedly connected to the top of the fixed seat.

[0006] Preferably, the rotating rod extends downward through the fixed seat movably, and a first motor is fixedly connected to the bottom of the inner wall of the fixed seat. The output end of the first motor is fixedly connected to the extended end of the rotating rod.

[0007] Preferably, a moving device is provided on the box body. The moving device includes a lead screw, which is rotatably connected to the front inner wall of the box body through a bearing. A moving block is slidably connected to the outer wall of the lead screw. A limiting rod is fixedly connected to the front inner wall of the box body, and the moving block is slidably connected to the outer wall of the limiting rod.

[0008] Preferably, the lead screw extends forward through the box body movably, and a second motor is fixedly connected to the front inner wall of the box body. The output end of the second motor is fixedly connected to the extended end of the lead screw.

[0009] Preferably, a cutting tool body is fixedly connected to the bottom of the moving block, and a box door is hinged to the front inner wall of the box body.

[0010] The advantages of this application are as follows:

[0011] In this application, by setting a clamping device, the spring is placed on the top of the bracket. The first motor is started, and the output end of the first motor drives the rotating rod to rotate. The rotating rod drives the rotating block to rotate. The rotating block drives the movable rod to move to the right. The movable rod drives the clamping block to move to the right. The clamping block drives the bottom slider to slide on the inner wall of the chute, which is used to limit the moving track of the clamping block. At the same time, the rotating block rotates to drive the two clamping blocks to move towards the middle to clamp the ceiling spring, thus solving the problem in the background art that the spring is not fixed during cutting, but during cutting, it is easy to deviate and cause low cutting accuracy.

[0012] Second, in the present application, a mobile device is provided. The second motor drives the lead screw to rotate, and the lead screw drives the moving block to move back and forth. Driven by the motor, the lead screw generates a back-and-forth movement. The moving block is limited by the limiting rod, and the limiting rod is used to restrict the movement range of the moving block to ensure that it moves within the specified position. The moving block drives the cutting tool body to move, thereby accurately cutting the hanger spring. This automated cutting device improves production efficiency and ensures the accuracy and consistency of the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS
