Description

Technical Field

[0001] The utility model relates to the technical field of wire processing, in particular to a length meter for wire processing. Background Art

[0002] The descriptions in this section only provide background information related to the present disclosure and do not constitute prior art.

[0003] With the rapid development of economic construction, the equipment in the construction industry is gradually updated. Automatic straightening machines are widely used in the field of construction machinery and equipment. In the production process of steel bars, especially in the production of wire bars, in order to facilitate wire transportation, the wire bars are often coiled into circular coils. Therefore, before production, the coiled bars need to be straightened and cut, and the straightening machine is a commonly used straightening and cutting device. The length meter on the discharge rack of the straightening machine is an indispensable and important part of the bar processing equipment, especially in the wire production process. At present, the length meters of traditional straightening machines use manual adjustment and bolt clamping, which have cumbersome procedures, long time consumption, and seriously affect the measurement accuracy, measurement efficiency of wire dimensions and the straightening output.

[0004] The utility model patents with the publication number CN213195415U, titled "Reinforcing bar straightening machine with optimized length meter installation" and the publication number CN214133726U, titled "Length meter of straightening machine", although both can measure the length of steel bars, they both have the following problems: when adjusting the distance between the two clamping length meters, one length meter is fixed and the position of the other length meter is adjustable. Therefore, when the diameter of the steel bar changes, the central axis of the steel bar will move up or down, resulting in the bending or rotation of the steel bar wire, thereby affecting the measurement accuracy and dimensional stability of the steel bar wire. Summary of the Utility Model

[0020] An upper wheel frame rotatably mounted on the bracket through a fixed rotating shaft, and the upper pressing part is rotatably mounted on the upper wheel frame;

[0021] A lower wheel frame rotatably mounted on the bracket through another fixed rotating shaft and located directly below the upper wheel frame, and the lower pressing part is rotatably mounted on the lower wheel frame;

[0022] The upper wheel frame and the lower wheel frame are meshed by tooth - shape to realize that when one rotates along the fixed rotating shaft, the other rotates synchronously in the opposite direction.

[0033] (1). By setting the self-centering clamping mechanism in the present utility model, when measuring the length dimension of steel wire bars with different diameter sizes, it can clamp the steel wire bars without changing the center line of the steel wire bars, thereby avoiding the rise or fall of the center line of the steel wire bars due to the increase or decrease of the diameter size of the steel wire bars, and thus avoiding the bending or rotation of the steel wire bars, which leads to the reduction of the counting and measuring accuracy, and ensuring the stability of the size measurement of the steel wire bars; by setting the linkage part, the upper pressing part and the lower pressing part can move towards or away from each other simultaneously, and further realize simultaneous clamping or simultaneous reverse loosening, so that the length meter is not affected by the thickness of the wire.

[0056] In order to solve the limitations of the prior art, this embodiment provides a technical solution. The following further explains the technical solution of the present utility model in conjunction with the accompanying drawings and embodiments.

[0057] The present utility model discloses a length counter for wire processing, which is mainly used for measuring the length of wire-shaped products such as steel bars. The measurement mainly adopts the principle of contact measurement. The technical improvement of the present utility model mainly aims at the problems of poor measurement accuracy and poor dimensional stability when measuring steel bar wires with different diameters.

[0058] Embodiment 1

[0059] See the attached Figures 1-6, A length meter for wire processing, comprising: a bracket 100 for mounting a counting and output mechanism 200 and a self-centering clamping mechanism 300. Specifically, the bracket 100 includes a horizontal bottom plate and a vertical plate vertically installed on the horizontal bottom plate. The counting and output mechanism 200 is installed on the vertical plate, and a fixed rotating shaft 700 is also rotatably installed on the vertical plate. A self-centering clamping mechanism 300 for clamping the clamped wire 500 while ensuring that the height of the central axis of the clamped wire 500 remains unchanged. Specifically, the self-centering clamping mechanism 300 includes: an upper pressing part 301 for pressing the upper side of the clamped wire 500, a lower pressing part 302 for cooperating with the upper pressing part 301 to press the lower side of the clamped wire 500. Both the upper pressing part 301 and the lower pressing part 302 are set in a disc shape, and the pressing surface is the circumferential side surface of the disc. A linkage part for connecting the upper pressing part 301 and the lower pressing part 302 to generate opposite clamping forces between the upper pressing part 301 and the lower pressing part 302 to clamp clamped wires 500 of different sizes. Specifically, the linkage part adopts a tooth engagement, a connecting rod 800, a chain or a screw rod structure. When using tooth engagement, the linkage part includes: an upper wheel frame 303 set in a plate shape, one end of which is rotatably installed on the bracket 100 through the fixed rotating shaft 700, and the upper pressing part 301 is rotatably installed on the upper wheel frame 303; a lower wheel frame 304, one end of which is rotatably installed on the bracket 100 through another fixed rotating shaft 700 and is located directly below the upper wheel frame 303, and the lower pressing part 302 is rotatably installed on the lower wheel frame 304. Here, both the upper pressing part 301 and the lower pressing part 302 are rotatably installed on the upper wheel frame 303 and the lower wheel frame 304 respectively by movable rotating shafts 305, and both the upper pressing part 301 and the lower pressing part 302 are located on the same side of the fixed rotating shaft 700; the upper wheel frame 303 and the lower wheel frame 304 are engaged by teeth to achieve synchronous rotation of the other in the opposite direction when one rotates along the fixed rotating shaft 700. Here, it can be understood that when the upper wheel frame 303 rotates downward along the fixed rotating shaft 700, the tooth engagement between the upper wheel frame 303 and the lower wheel frame 304 drives the lower wheel frame 304 to rotate upward, thereby realizing the approaching and clamping actions of the upper pressing part 301 and the lower pressing part 302. Specifically, an upper arc tooth 306 is provided at the bottom edge of the upper wheel frame 303, and a lower arc tooth 307 is provided at the top edge of the lower wheel frame 304. The upper arc tooth 306 and the lower arc tooth 307 are engaged and installed. Here, the meaning of the arc tooth is that the arrangement of the teeth is in an arc, adapting to the rotation actions of the upper wheel frame 303 and the lower wheel frame 304 along the fixed rotating shaft 700. A pre-tightening mechanism 600 for applying a pre-tightening force to the upper pressing part 301 or the lower pressing part 302. Specifically, the pre-tightening mechanism 600 adopts a spring, a screw tightening, a pneumatic mechanism or a hydraulic mechanism. When using a spring, the pre-tightening mechanism 600 includes: an adjusting column installed on the bracket 100 through a nut and the bottom of which presses against the top of the upper wheel frame 303. Here, the bottom of the adjusting column can be understood as the nut end of the screw, that is, the end away from the nut; a spring sleeved on the adjusting column and located between the bottom of the adjusting column and the bracket 100.

[0060] A counting and output mechanism 200 is used to count and output the length of the clamped wire 500 passing through the self-centering mechanism. The counting and output mechanism 200 adopts a mechanical counter, an electronic encoder or a light sensor counter, and the number is at least one. It also includes a guiding mechanism 400, which is installed on the bracket 100 to guide the clamped wire 500. Specifically, there are two guiding mechanisms 400, which are respectively located on both sides of the self-centering clamping mechanism 300. The guiding mechanism 400 is set as a circular ring structure installed on the bracket 100, and the central direction of this circular ring structure is collinear with the midline between the upper pressing part 301 and the lower pressing part 302.

[0061] When using the above-mentioned length measuring device to measure the size of the wire, the steel bar wire passes through one guiding mechanism 400, then passes between the upper pressing part 301 and the lower pressing part 302, and then passes through another guiding mechanism 400 and exits. At this time, under the pre-tightening force of the spring, the upper wheel frame 303 and the lower wheel frame 304 are engaged to drive the upper pressing part 301 and the lower pressing part 302 to clamp the wire. While the wire moves, the counting and output mechanism 200 measures the length of the wire; when replacing a wire with a small diameter, under the action of the pre-tightening force of the spring, the upper wheel frame 303 remains in contact with the upper surface of the wire, so the upper wheel frame 303 rotates clockwise along the fixed rotating shaft 700. At this time, the lower wheel frame 304 rotates counterclockwise because it is engaged with the upper wheel frame 303, so as to realize the lowering of the upper pressing part 301 and the rising of the lower pressing part 302, and further press the wire tightly. On the contrary, when replacing a wire with a large diameter, the upper wheel frame 303 rotates counterclockwise and the lower wheel frame 304 rotates clockwise to continue clamping the wire.

[0062] Embodiment 2

[0063] See the appendix Figure 7 Differing from Embodiment 1, the linkage part includes: an upper wheel frame 303, which is rotatably installed on the bracket 100 through a fixed rotating shaft 700, and the upper pressing part 301 is rotatably installed on the upper wheel frame 303; a lower wheel frame 304, which is rotatably installed on the bracket 100 through another fixed rotating shaft 700 and is located directly below the upper wheel frame 303, and the lower pressing part 302 is rotatably installed on the lower wheel frame 304; the upper wheel frame 303 and the lower wheel frame 304 are connected by a connecting rod 800 to realize that when one rotates along the fixed rotating shaft 700, the other rotates synchronously in the opposite direction. One end of the connecting rod is rotatably installed on the upper wheel frame 303, and the other end is rotatably installed on the lower wheel frame 304. It can be understood that on the upper wheel frame 303, the position of the fixed rotating shaft 700 is between the position of the connection between the upper pressing part 301 and the connecting rod 800, and on the lower wheel frame 304, the position of the connection of the connecting rod 800 is between the position of the fixed rotating shaft 700 and the lower pressing part 302.

[0064] When using the linear meter of this embodiment to measure the size of a wire, the steel bar wire is located between and in contact with the upper pressing part 301 and the lower pressing part 302. When replacing a wire with a smaller size, under the action of the spring, the upper wheel frame 303 rotates clockwise along the fixed rotating shaft 700, and the upper pressing part 301 descends. At this time, the other end drives the connecting rod 800 to rise. At the same time, the rising of the connecting rod 800 drives the lower wheel frame 304 to rise, and the upper wheel frame 303 drives the lower pressing part 302 to rise, thereby completing the continuous clamping action on the wire.

[0065] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.

[0066] The foregoing is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
