Problems solved by technology

Therefore, it is necessary to control the length of the raw material wire released from the winding reel. At present, more control methods are to control the number of rotations of the winding reel or to control the rotation time of the motor. The winding reel rotates the same number of turns or the motor rotates for the same time, but the length of the wire released from the winding reel may be different, which cannot be precisely controlled, and the length of the raw material wire released is not only unsightly, but also may be stuck in other parts on, easy to damage parts

Embodiment 1

[0020] Such as figure 1 As shown, the spring wire feeder with the function of precisely controlling the length of the incoming wire of the present invention includes a bracket 8, a wire storage control mechanism and a wire entry control mechanism, and the wire storage control mechanism includes a guide rod 1, a pulley 3, and a threader 2, wherein , the pulley 3 is fixed on the upper end of the bracket 1, the guide rod 1 is fixed on the lower end of the bracket 1, the threader 2 is movably connected to the guide rod 1, and can move up and down along the guide rod 1, so as to realize the storage of the raw material wire 9 and the control of the wire speed The threader 2 is for example but does not include a support plate provided with a thread hole, a cylindrical mechanism, such as a roller, a pulley, etc.; the thread storage control mechanism also includes an opening touch device 41 and a Close the touch control device 42, both of which are connected with the incoming line cont...

Embodiment 2

[0022] The present invention is on the basis of embodiment 1:

[0023] The threader 2 further includes a support plate and a pulley fixed on the support plate, the support plate is provided with at least 2 wire passing holes, so that the raw material wire 9 is wound around the lower end of the pulley on the support plate through the two wire passing holes; Bolts are connected to the positions corresponding to the guide rod 1 at both ends of the support plate, and copper sheets that are in sliding contact with the guide rod 1 are fixed on the bolts, so that the support plate and the guide rod 1 are freely slidably connected, so as to facilitate wire storage and wire entry control;

[0024] In addition, in order to obtain a better balance effect for the needle threader 2, the number of the above-mentioned guide rods 1 is 2;

[0025] In order to make the raw material wire 9 enter the spring production equipment more conveniently, at least two fixed pulleys are arranged on the ab...

Abstract

The invention discloses a spring wire feeder with an accurate wire feeding length control function. The spring wire feeder comprises a support (8), a wire storage control mechanism and a wire feeding control mechanism. The wire storage control mechanism comprises a guide rod (1), a pulley (3) and a wire threader (2). The pulley (3) is fixed at the upper end of the support (1), the guide rod (1) is fixed at the lower end of the support (1), and the wire threader (2) is movably connected onto the guide rod (1). The wire storage control mechanism further comprises a starting touch device (41) and a closing touch device (42) which are respectively fixed at the upper end and the lower end of the guide rod (1) and connected with the wire feeding control mechanism. The wire feeding control device can accurately control wire feeding length, effectively controls wire feeding speed of a raw material wire, stores the raw material wire, enables the raw material wire to keep certain tension at any time and has the advantages of being simple and compact in structure, low in cost and the like.

Description

technical field [0001] The invention relates to the field of spring processing, in particular to a spring wire feeder used in spring production with the function of precisely controlling the length of the incoming wire. Background technique [0002] In the spring production line, since the raw wire is generally coiled on the winding reel, it is necessary to use a wire feeder for control. Present wire feeder generally comprises winding reel, support, electric control box, motor, controls motor rotation by electric control box, thereby drives winding reel to rotate, and emits raw material wire. [0003] In order to ensure the production quality of the spring, it is necessary to ensure that the feeding speed of the raw material wire is consistent, and the raw material wire should be kept at a certain tension as much as possible. Therefore, it is necessary to control the length of the raw material wire released from the winding reel. At present, more control methods are to con...
