Description

Technical Field

[0001] This utility model belongs to the technical field of drawing machine equipment and specifically relates to an adjustable chuck device for a drawing machine. Background Technology

[0002] Currently, the most common chucks used in drawing machines are chain chucks. At the interface of the wire or pipe, a wedge block needs to be hammered into the chuck to achieve the purpose of clamping. Moreover, if one side of the wedge block has serrations, the clamping effect is not good. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an adjustable chuck device for a drawing machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An adjustable chuck device for a drawing machine includes a chuck device body, a pull rod, a chuck component, a push retractor, and an elastic element;

[0006] The chuck device body has a cavity for placing the push retractor, the chuck component and the elastic element. One end of the chuck device body has an opening communicating with the cavity. The chuck component and the push retractor are slidably engaged with the cavity. The chuck component has an adjustable clamping part.

[0007] The two ends of the elastic element are respectively connected to the clamping component and the inner wall surface of the cavity;

[0008] One end of the tie rod is located inside the cavity and is hinged to the push retractor;

[0009] One end of the push retractor is connected to the clamp head;

[0010] As the pull rod rotates relative to the chuck device body and the push retractor drives the chuck component to extend from the opening, the size of the clamping part decreases, and the elastic element is in a compressed state at this time.

[0011] As the pull rod rotates relative to the chuck device body and the push retractor drives the chuck component to retract from the opening, the size of the clamping part increases, and the elastic element is in a compressed state.

[0012] Preferably, the chuck device body includes a base, a top plate, and fixing bolts, wherein the base and the top plate are connected by the fixing bolts to form the chuck device body.

[0013] Preferably, the cavity is located on the base, and the cavity has a guide bevel that cooperates with the clamp component.

[0014] Preferably, the chuck component includes two symmetrically arranged chucks, each chuck having a wedge-shaped structure, an inner end face and an outer end face, the inner end faces of the two chucks being arranged opposite each other to form the clamping portion, and the outer end faces of the two chucks engaging with the guide bevel of the cavity.

[0015] Preferably, the inner end face of the chuck is provided with serrations.

[0016] Preferably, the clamp is provided with a connecting hole for connection with the elastic element.

[0017] Preferably, the push retractor includes a connecting part hinged to the pull rod and a hook part connected to the clamping member. A connecting rod is provided between the two clamping members. The hook part cooperates with the connecting rod, and the connecting rod slides with the clamping member.

[0018] Preferably, the cavity is provided with a first limiting through hole, the top plate is provided with a second limiting through hole, one end of the pull rod passes through the second limiting through hole and is hinged to the push retractor, and the end of one end of the pull rod cooperates with the first limiting through hole.

[0019] Preferably, the pull rod includes a first pull rod portion and a second pull rod portion that are inclined to each other, the first pull rod portion passing through the second limiting through hole and hinged to the push retractor.

[0020] Preferably, the other end of the chuck device body is provided with a connection port for connecting to the drawing machine.

[0021] Compared with the prior art, the beneficial effects of this utility model include:

[0022] The adjustable clamping device of this application can be installed on various types of drawing machines, such as straight drawing and coil drawing machines. During use, the pull rod rotates relative to the clamping device body, causing the clamping component to retract from the opening. At this time, the size of the clamping part increases, and the wire or pipe is placed in the clamping part. When the force on the pull rod is released, under the elastic force of the elastic element, the pull rod rotates in the opposite direction relative to the clamping device body. At this time, the clamping component extends from the opening, and the size of the clamping part decreases, thereby clamping and fixing the wire or pipe. The above structure, based on the elastic element always exerting a compressive elastic force on the clamping component, can ensure the clamping force of the clamping part and the stability of the clamping fixation. At the same time, the size of the clamping part can be changed, thus adapting to wires and pipes of different sizes. Attached Figure Description

[0035] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] Example:

[0038] like Figure 1-5 As shown, this embodiment provides an adjustable chuck device for a drawing machine, including a chuck device body 1, a pull rod 2, a chuck component 3, a push retractor 4, and an elastic element 5;

[0039] The chuck device body 1 is provided with a cavity 101 for placing the push retractor 4, the chuck component 3 and the elastic element 5. One end of the chuck device body 1 is provided with an opening 108 communicating with the cavity 101. The chuck component 3 and the push retractor 4 are slidably engaged with the cavity 101. The chuck component 3 is provided with a clamping part 301 with adjustable size.

[0040] The two ends of the elastic element 5 are respectively connected to the clamping component 3 and the inner wall surface of the cavity 101;

[0041] One end of the tie rod 2 is located inside the cavity 101 and is hinged to the push retractor 4;

[0042] One end of the push retractor 4 is connected to the clamp head;

[0043] As the pull rod 2 rotates relative to the chuck device body 1 and the push retractor 4 drives the chuck component 3 to extend from the opening 108, the size of the clamping part 301 decreases, and the elastic element 5 is in a compressed state at this time.

[0044] As the pull rod 2 rotates relative to the chuck device body 1 and the push retractor 4 drives the chuck component 3 to retract from the opening 108, the size of the clamping part 301 increases, and at this time the elastic element 5 is in a compressed state.

[0045] The adjustable clamping device of this embodiment can be installed on various types of drawing machines such as straight drawing and coil drawing machines. In use, the pull rod 2 rotates relative to the clamping device body 1, causing the clamping part 3 to retract from the opening 108. At this time, the size of the clamping part 301 increases, and the wire or pipe is placed in the clamping part 301. When the force on the pull rod 2 is released, under the elastic force of the elastic member 5, the pull rod 2 rotates in the opposite direction relative to the clamping device body 1. At this time, the clamping part 3 extends from the opening 108, and the size of the clamping part 301 decreases, thereby clamping and fixing the wire or pipe. The above structure ensures the clamping force of the clamping part 301 and the stability of the clamping fixation by ensuring that the elastic member 5 always has a compressive elastic force on the clamping part 3. At the same time, the size of the clamping part 301 can be changed, so that it can be used for wires and pipes of different sizes.

[0046] The specific structure of the chuck device body 1 in this embodiment is as follows:

[0047] It includes a base 102, a top plate 103 and a fixing bolt 104. The base 102 and the top plate 103 are connected by the fixing bolt 104 to form the chuck device body 1.

[0048] Specifically, the cavity 101 is located on the base 102, and the cavity 101 is provided with a guide slope 105 that cooperates with the chuck component 3.

[0049] Meanwhile, the clamp component 3 of this embodiment includes two symmetrically arranged clamping members 302. The clamping members 302 have a wedge-shaped structure and have inner and outer end faces. The inner end faces of the two clamping members 302 are arranged opposite each other to form a clamping part 301, and the outer end faces of the two clamping members 302 cooperate with the guide inclined part 105 of the cavity 101. It should be noted that the elastic members 5 are spring members, and there are two of them, corresponding to the two clamping members 302. The two elastic members 5 act on the clamping members 302 respectively to ensure the clamping force of the two clamping members 302, so that the wire or pipe between the clamping members 302 is more stable.

[0050] In the above structure, when the two clamping members 302 move along the guide slope 105, the distance between the two clamping members 302 changes, thereby achieving the effect of changing the size of the clamping part 301.

[0051] The inner end face of the chuck 302 is provided with serrations 303. The structure of the serrations 303 can increase the friction with the wire or tube, thereby effectively clamping the wire or tube to be pulled.

[0052] In this embodiment, the clamp 302 is provided with a connection hole 304 that connects to the elastic member 5.

[0053] The specific structure of the propulsion retractor 4 in this embodiment includes a connecting part 401 hinged to the pull rod 2 and a hook part 402 connected to the clamping member 3. A connecting rod is provided between the two clamping members 302. The hook part 402 cooperates with the connecting rod, and the connecting rod slides with the clamping member 302. When the two clamping members 302 move along the guide slope 105, the distance between the two clamping members 302 changes, so that the clamping members 302 can slide on the connecting rod, ensuring the stability of the dimensional change process of the clamping part 301.

[0054] In this embodiment, a first limiting through hole 106 is provided at the cavity 101, and a second limiting through hole 107 is provided at the top plate 103. One end of the pull rod 2 passes through the second limiting through hole 107 and is hinged to the push retractor 4. The end of one end of the pull rod 2 is engaged with the first limiting through hole 106.

[0055] The specific structure of the tie rod 2 in this embodiment includes a first tie rod part 201 and a second tie rod part 202 that are connected at an incline to each other. The first tie rod part 201 passes through the second limiting through hole 107 and is hinged to the push retractor 4.

[0056] Specifically, the other end of the clamping device body 1 is provided with a connection port 109 for connecting various types of drawing machines such as straight drawing machines and coil drawing machines.

[0057] In summary, this application can effectively clamp and fix wires and pipes through the structure of the elastic element 5 and the serration 303. At the same time, the size of the clamping part 301 can be adjusted, making it more adaptable to wires and pipes of various diameters. The clamping operation is also convenient and quick, making it easy to promote.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
