Description

Cutter assembly for limiting clamping hook of torsion spring

Technical Field

The utility model belongs to the technical field of the torsional spring technique and specifically relates to a cutter unit for spacing pothook of torsional spring.

Background

The torsion spring belongs to a spiral spring, and can store and release angular energy or statically fix a certain device by rotating a force arm around a central shaft of a spring body. The ends of the torsion spring are fixed to the other components, and as the other components rotate about the spring center, the spring pulls them back to the original position, creating a torque or rotational force.

The limiting hook of the existing torsion spring is generally manufactured by a mode of cutting off at right angles, and is cut out by a machine, but the torsion spring manufactured by the method has poor quality and poor product stability.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the utility model provides a adopt and dash the area and cut direct manufacturing out spacing pothook, the equal better cutter subassembly for spacing pothook of torsional spring of product stability and quality.

The utility model provides a technical scheme that its technical problem adopted is: a cutter component for a limiting hook of a torsion spring comprises a first cutter and a second cutter, wherein a stamping cutter head is arranged at the end part of the first cutter, one side edge of the stamping cutter head is an arc surface, and the arc surface is in contact with a wire; an open slot and a wire clamping slot are formed in the end portion of the second cutter, the open slot and the wire clamping slot are vertically arranged, a wire is clamped in the wire clamping slot, and a punching cutter head of the first cutter punches and cuts the wire at the open slot.

Furthermore, the cross section of the stamping cutter head is U-shaped.

Further, the axis of the opening groove is coincided with the axis of the punching tool bit.

Furthermore, the wire clamping groove is formed in the edge of the end face of one end of the second cutter.

The utility model has the advantages that: the utility model discloses simple structure is novel, adopts even to dash to take to cut and directly makes out spacing pothook, and this kind is directly dashed out with the cutter, therefore the stability and the quality of product are all better, and work efficiency is high, and direct mount is on the coiling machine, easy operation.

Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The cutter assembly for the torsion spring limiting hook shown in fig. 1 to 4 comprises a first cutter 1 and a second cutter 2, wherein the first cutter 1 and the second cutter 2 are vertically arranged, a stamping cutter head 3 is arranged at the end part of the first cutter 1, one side edge of the stamping cutter head 3 is an arc surface, and the arc surface is in contact with a wire;

an open slot 4 and a wire clamping slot 5 are formed in the end portion of the second cutter 2, the open slot 4 and the wire clamping slot 5 are vertically arranged, a wire is clamped in the wire clamping slot 5, and the punching cutter head 3 of the first cutter 1 punches and cuts the wire at the open slot 4.

The cross section of the punching tool bit 3 is U-shaped, the cross section of the opening groove 4 is also U-shaped, and the arc surface of the punching tool bit 3 faces the arc bottom surface of the opening groove 4.

The axis of the open slot 4 is coincident with the axis of the punching tool bit 3, so that the superimportant tool bit 3 can be punched into the open slot 4.

Wherein, the wire clamping groove 5 is arranged at the edge of one end face of the second cutter 2.

Specifically be the vertical state with first cutter 1 and second cutter 2 and install on the coiling machine, in the production process of the spacing pothook of torsional spring, wire rod is blocked to card wire casing 5 on the second cutter 2, then the wire rod of 4 openings of open slot openings are aimed at to the arcwall face of the punching press tool bit 3 of second cutter 1 carries out the punching press, and at this moment, the punching press of spacing pothook is the right angle and cuts off through the notch on card wire casing 5, accomplishes the preparation of the spacing pothook of torsional spring.

While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
