Description

Technical Field

[0001] The utility model relates to the technical field of gold-making devices, in particular to a metalworking wire drawing stool. Background Art

[0002] The wire drawing operation of gold and silver jewelry is to pass the metal wire through a wire drawing plate with a specific aperture to obtain a metal wire of the desired thickness. In order to avoid the time-consuming and laborious problem of manual wire drawing, some wire drawing bench products have appeared on the market. By fixing the wire drawing plate at one end, one end of the metal wire passing through the wire drawing hole is pulled through a clamp. In order to further improve work efficiency, the existing wire drawing bench fixes the clamp to one end of a belt or cable, and the other end of the belt or cable is wound through a turntable at the other end of the wire drawing bench, thereby driving the clamp and completing the wire drawing of the metal wire clamped by the clamp. This improved structure avoids the labor and difficulty of manual wire drawing and improves work efficiency to a certain extent, but the following problems still exist:

[0003] 1. The belt or cable used to connect and fix the clamp needs to be wound to drive the clamp to move along the wire drawing bench. Therefore, the flexible material characteristics of the belt or cable lead to instability during its movement, such as left-right or up-and-down shaking, which directly affects the direction of the wire during the wire drawing process and interferes with the smoothness of the wire drawing process.

[0004] Second, the existing wire-pulling stool equipment has a fixed length and can only pull a certain length of metal wire, and cannot meet the needs of pulling longer metal wires at one time with higher efficiency. Simply increasing the length of the wire-pulling stool not only increases production costs, but also takes up more space during work, making it inconvenient to use and store.

[0005] In order to better solve the problems existing in the prior art, the present application has developed a metalworking wire drawing stool that is practical, convenient and efficient in wire drawing. Utility Model Content

DETAILED DESCRIPTION

[0046] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods in combination with the accompanying drawings.

[0047] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0048] Example 1

[0049] like Figure 1-5 , shows the overall structure of an embodiment of the metalworking wire drawing bench, which includes a wire drawing bench body, which includes a supporting leg 1, a supporting groove 2 is arranged at the top of the supporting leg, a wire drawing plate fixing structure is arranged at the left end of the supporting groove, a hand-cranked turning handle 3 is arranged at the right end of the supporting groove, and a clamp bearing structure is arranged in the supporting groove, and the clamp bearing structure is driven by the hand-cranked turning handle to move along the length direction of the supporting groove; a wire winding roller 4 is detachably provided on the clamp bearing structure, and a notch 401 for winding and fixing the end of the metal wire is arranged on the wire winding roller, and the width of the notch is set smaller than the outer diameter of the wire winding roller; the notch is set to pass through the side wall of the wire winding roller in the width direction.

[0050] The clamp bearing structure includes a lead screw 5 and a lead screw slider 6, and a top seat 7 is connected above the lead screw slider. The top seat is surrounded by a side plate 701 and a bottom plate 702. An opening 703 is set on the side plate 701 of the top seat close to the wire drawing plate fixed structure. The opening is for the front part of the clamp 8 placed on the top seat to extend out. The opening cooperates with the clamp to pull the metal wire passing through the wire winding plate fixed structure during the movement of the top seat along the lead screw. The top seat 7 is open on one side corresponding to the hand-cranked handle, and two corresponding upper notches 704 are set on the other two side plates of the top seat. The two ends of the wire winding roller extend outward from the upper notches.

[0051] The opening is a long strip opening with a width matching the front of the clamp. As the top seat moves, the clamp holding the end of the metal wire gradually tightens and pulls the metal wire to move from the corresponding hole of the wire drawing plate fixing structure.

[0052] The winding roller 4 comprises a roller shaft 402 and a roller drum 403 disposed outside the roller shaft, bearings 404 are respectively sleeved on the ends of the roller shaft at both ends of the roller drum, and a rotating handle 405 is fixed to one end of the roller shaft. Bearing support plates 705 are disposed outside the two opposite side walls of the top seat 7, and bearing seats matching the bearings 404 at both ends of the roller shaft are disposed on the bearing support plates.

[0053] The above-mentioned supporting groove 2 is surrounded by two groove side plates 201 and a groove bottom plate 202. The wire drawing plate fixing structure is arranged between one end of the two groove side plates, and a connecting plate 203 is arranged between the other ends of the two groove side plates; the clamp bearing structure is slidably arranged above the groove side plates 201, and under the drive of the hand-cranked handle 3, the clamp bearing structure moves along the length direction of the groove side plates.

[0054] L-shaped recesses 706 are provided at the bottom ends of the two opposite side plates of the top seat 7 , and the top seat is slidably disposed above the groove side plates 201 through the L-shaped recesses.

[0055] The aforementioned support legs 1 are welded to the bottom end of the above-mentioned trough bottom plate 202, and there are four of them in total; a horizontal connecting beam 101 is fixedly connected between each support leg. The fixed support legs ensure the overall stability of the metalworking wire drawing bench and improve the wire drawing work efficiency.

[0056] The above-mentioned wire drawing plate fixing structure includes a fixed plate 9 and an adjustable movable plate 10. The fixed plate is arranged at the left end of the supporting channel 2, and an inverted trapezoidal opening 11 is arranged on the fixed plate; the adjustable movable plate includes a fixed flat plate and two L-shaped plate bodies arranged on the fixed flat plate at intervals, threaded holes are correspondingly arranged on the fixed flat plate and the L-shaped plate body, and the fastening bolts pass through the threaded holes to fix the position of the L-shaped plate body on the fixed flat plate. The structural setting of the fixed flat plate and the L-shaped plate body is a conventional setting structure, and no markings are made to indicate the fixed flat plate and the L-shaped plate body. The adjustable movable plate adjusts the horizontal spacing between it and the fixed plate 9 through this structure to meet the placement of wire drawing plates 12 of different thicknesses.

[0057] The fixing plate 9 is disposed between the left ends of the two slot side plates 201; the fixing plate 9, the slot side plates 201, the slot bottom plate 202 and the connecting plate 203 together form the supporting slot 2. The two ends of the lead screw are fixed to the fixing plate and the connecting plate 203 respectively.

[0058] A receiving cavity 204 is provided on one side of the support channel 2. The receiving cavity is surrounded by an outer protective plate along the length direction of the support channel, and a partition plate 205 is provided in the receiving cavity.

[0059] When in use, the wire drawing plate 12 is fixed between the fixed plate 9 and the adjustable movable plate 10 of the wire drawing plate fixing structure, and the hole through which the metal wire needs to pass is exposed at the inverted trapezoidal opening 11; then, the clamp 8 is placed on the bottom plate 702 of the top seat 7, so that its clamping mouth extends out of the opening 703 to the left side of the supporting groove. At this time, the clamp can be freely opened to a certain angle and can clamp the end of the metal wire; the lead screw 5 is rotated by the hand-cranked turning handle 3, so that the lead screw rotates and drives the top seat 7 above the lead screw slider 6 to move to the left and close to the fixed plate 9, and then, the wire winding roller 4 is stably squatted in the upper recess 704 on the top seat 7 through the bearing 404. The metal wire to be drawn is passed through the corresponding hole on the drawing plate 12 and clamped by the clamp 8, and the hand-cranked handle 3 is continuously rotated in the opposite direction, so that a pulling force is formed between the metal wire and the clamp. Under the action of this force, the clamp handle of the clamp is stuck in the opening 703 position. As the hand-cranked handle is rotated, the screw slider 6 drives the top seat 7 and the clamp 8 arranged thereon to move away from the fixed plate 9, so as to achieve a tighter clamping and drawing of the metal wire. When the top seat 7 moves to one end close to the hand-cranked handle 3, in order to achieve a longer distance of wire drawing of the metal wire, the end connected to the clamp 8 can be removed from the clamp, and then wound several times through the notch 401 on the wire winding roller 4, and then wound onto the roller 403, and the rotating handle 405 of the wire winding roller is rotated to allow the metal wire to continue to be wound and drawn, thereby solving the problem of limited drawing length of the existing wire drawing bench structure.

[0060] When the wire drawing is finished, the metal wire can be removed from the wire winding roller 4. When the clamp 8 and the wire winding roller 4 are not in use, they can be placed in the storage cavity.

The difference is that Figure 6 , showing the main difference structure of the metalworking wire drawing bench: the clamp bearing structure includes a screw 5 and a slider 13, an opening 14 for the screw to pass through is arranged on the slider, an internal thread is arranged on the inner top side of the opening, and the bottom end of the opening is open; the internal thread of the opening matches the external thread of the screw.

[0063] This structural setting enables the clamp bearing structure to be removed from the supporting channel 2, which is convenient for use and does not affect normal wire drawing.

[0064] The usage and process of the metalworking drawing stool refer to the usage in Example 1 and will not be described in detail here.

[0065] Example 3

[0066] like Figure 7 , showing the overall structure of another embodiment of the metalworking wire drawing stool. The structure of the metalworking wire drawing stool is the same as that of the metalworking wire drawing stool in Example 1, except that the hand-cranked turning handle 3 is replaced by an electric drive mechanism. Specifically, the reduction motor is supported and fixed on the outer plate 15 set at the right end of the support groove, and the reduction motor is accommodated by the housing 16, and the output shaft of the reduction motor is fixedly connected to the right end of the lead screw.

[0067] As an alternative, the drive motor may be disposed below the right end of the support groove 2, a chain is sleeved between the right end of the lead screw 5 and the output shaft of the drive motor, and the drive motor drives the lead screw to rotate via the chain.

[0068] As in the metalworking drawing stool structure of Examples 1-3, as an alternative implementation, two sets of supporting legs can be hingedly connected on both sides of the bottom end of the groove bottom plate 202; through the hinged manner, the metalworking drawing stool can be conveniently stored when not in use.
