Description

Technical fields:

[0001] This utility model relates to the technical field of steel bar stretching wire processing equipment, and more specifically to a steel wire tension adjustment mechanism for a wire drawing machine. Background technology:

[0002] The existing method of drawing steel bars involves cold drawing the steel bars to lengthen and thin them, and then winding them into coils. Generally, the diameter of the steel wires in the coils is relatively large at this stage. Therefore, it is necessary to place them in the corresponding drawing equipment for secondary drawing to gradually lengthen them and reduce their outer diameter to meet the processing requirements.

[0003] During the drawing process in a wire drawing machine, it is necessary to ensure a certain tension of the incoming steel wire and to guide it. The existing method is to fix a guide roller support frame on the rear wall of the wire drawing machine, and fix multiple guide rollers on the guide roller support frame to guide the wire. However, the distance between the guide roller support frame and the drawing die is too short, and the distance between the two cannot be adjusted, which makes it impossible to adjust the tension and has limited effectiveness. Utility Model Content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wire tension adjustment mechanism for a wire drawing machine. It can adjust the distance between the front tension roller device and the rear tension roller device and the main body of the wire drawing machine, thereby changing the tension. Moreover, it is easy to connect and disassemble with the main body of the wire drawing machine and to facilitate replacement.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A wire tension adjustment mechanism for a wire drawing machine includes a main frame body placed at the rear of the wire drawing machine host. The top surfaces of two transverse beams on the upper part of the main frame body are each fixed with a forward-extending transverse support adjustment screw. The extension screw is located at the front end of the corresponding transverse support adjustment screw. A transverse adjustment sleeve is screwed onto the transverse support adjustment screw and the extension screw. A gripping part is fixed on the outer wall of the middle part of the transverse adjustment sleeve.

[0007] The front end of the extension screw is fixed with a connecting block. The bottom surface of the connecting block is formed with an upwardly extending slot. The connecting block is located on the left or right side wall of the rear end of the wire drawing machine host. The limiting post fixed on the left or right side wall of the wire drawing machine host is inserted into the corresponding slot. The top surface of the limiting post presses against the top surface of the corresponding slot.

[0008] Rear bearing seats are fixed on the upper rear side walls of the two left and right support columns at the rear of the main frame. The two ends of the rear tensioning shaft are fixed in the inner rings of the two rear bearing seats. A rear tensioning roller device is installed on the rear tensioning shaft. Front bearing seats are fixed on the middle front side walls of the two left and right support columns at the front of the main frame. The two ends of the front tensioning shaft are fixed in the inner rings of the two front bearing seats. A front tensioning roller device is installed on the front tensioning shaft. The steel wire to be processed is conveyed forward from the rear and backward along the front tensioning roller device to the rear tensioning roller device, and then forward into the drawing die feed port of the drawing host fixed on the top rear part of the wire drawing machine host.

[0009] The rear ends of the two transverse beams are fixed to the front side wall of the middle of the two left and right support columns at the rear of the main frame, and the top surfaces of the two front left and right support columns are fixed to the bottom surface of the front of the transverse beams.

[0010] Bottom sliders are fixed to the bottom surfaces of the four support columns of the main frame. Two guide rails extending forward and backward are fixed to the ground behind the wire drawing machine. The upper part of the guide rails is inserted into the upward-extending guide groove formed in the middle of the bottom surface of the corresponding bottom slider.

[0011] The outstanding effect of this utility model is:

[0012] It can adjust the distance between the front tensioning roller device and the rear tensioning roller device and the main body of the wire drawing machine, thereby changing its tension. Moreover, it is easy to connect and disassemble with the main body of the wire drawing machine, and easy to replace. In addition, both the front tensioning roller device and the rear tensioning roller device are equipped with four guide rollers to achieve guiding support, and its guiding support effect is good.

[0014] Figure 2 This is a partial top view of the main frame;

[0015] Figure 3 This is a partial structural diagram of the connection block and the limiting post. Detailed implementation method:

[0016] For example, see below. Figures 1 to 3As shown, a wire tension adjustment mechanism for a wire drawing machine includes a main frame 10 placed behind the main body 100 of the wire drawing machine (which is an existing, known, and readily available product, and will not be described in detail here). Bottom sliders 1 are fixed to the bottom surfaces of the four support columns 16 of the main frame 10. Two guide rails 2 extending forward and backward are fixed to the ground behind the main body 100. The upper part of the guide rails 2 is inserted into an upwardly extending guide groove formed in the center of the bottom surface of the corresponding bottom slider 1. This structure allows the main frame 10 to move forward and backward along the guide rails 2.

[0017] The top surfaces of the two transverse beams at the upper part of the main frame 10 are each fixed with a forward-extending transverse support adjusting screw 11. An extension screw 12 is located at the front end of the corresponding transverse support adjusting screw 11. A transverse adjusting sleeve 13 is screwed onto the transverse support adjusting screw 11 and the extension screw 12. A gripping part 14 is fixed on the outer wall of the middle part of the transverse adjusting sleeve 13. The thread direction of the transverse support adjusting screw 11 and the thread direction of the extension screw 12 are opposite, so that when the transverse adjusting sleeve 13 is rotated, the corresponding transverse adjusting sleeve 13 and the extension screw 12 can be brought closer or moved further apart, thereby realizing the distance adjustment between the main frame 10 and the wire drawing machine host 100.

[0018] The front end of the extension screw 12 is fixed with a connecting block 15. The bottom surface of the connecting block 15 is formed with an upwardly extending slot 151. The connecting block 15 is located on the left or right side wall of the rear end of the wire drawing machine host 100. The limiting post 20 fixed on the left or right side wall of the wire drawing machine host 100 is inserted into the corresponding slot 151, and the top surface of the limiting post 20 presses against the top surface of the corresponding slot 151.

[0019] Rear bearing seats 17 are fixed on the upper rear side walls of the two left and right support columns 16 at the rear of the main frame 10. The two ends of the rear tensioning shaft 18 are fixed in the inner rings of the two rear bearing seats 17. A rear tensioning roller device 30 is installed on the rear tensioning shaft 18. Front bearing seats 161 are fixed on the front side walls of the middle of the two left and right support columns 16 at the front of the main frame 10. The two ends of the front tensioning shaft 19 are fixed in the inner rings of the two front bearing seats 161. A front tensioning roller device 40 is installed on the front tensioning shaft 19.

[0020] Furthermore, the front tensioning roller device 40 and the rear tensioning roller device 30 have the same structure, both including end connecting plates 31 fixed to the left and right parts of the rear tensioning shaft 18 or the front tensioning shaft 19. Guide rollers 32 extending to the left and right are installed between the front, rear, upper and lower parts of the two corresponding end connecting plates 31. The left and right ends of the guide rollers 32 are fixed to the two end connecting plates 31.

[0021] Furthermore, all guide rollers 32 between the two corresponding end connecting plates 31 are evenly distributed on the two end connecting plates 31 with the central axis of the front tensioning shaft 19 or the rear tensioning shaft 18 fixed to the two end connecting plates 31 as the center.

[0022] The outer side of the outer end of the limiting post 20 is formed with a radial extension edge 21, and the connecting block 15 is located between the corresponding radial extension edge 21 and the left or right side wall of the rear part of the wire drawing machine host 100.

[0023] Furthermore, the rear ends of the two transverse beams are fixed to the front side wall of the middle of the two left and right support columns 16 at the rear of the main frame 10, and the top surfaces of the two left and right support columns 16 at the front are fixed to the bottom surface of the front of the transverse beams.

[0024] In this embodiment, the steel wire to be processed is conveyed from the rear to the front and along the guide roller 32 of the front tensioning roller device 40 to the guide roller 32 of the rear tensioning roller device 30, and then conveyed forward into the drawing die feed port of the drawing host fixed on the rear top surface of the wire drawing machine host 100.

[0025] By rotating the two lateral adjusting sleeves 13, the distance between the corresponding lateral support adjusting screw 11 and extension screw 12 is changed, thereby changing the distance between the main frame 10 and the wire drawing machine host 100, and thus changing the tension of the wire drawing.

[0026] In this embodiment, a radially extending edge 21 is formed on the outer side of the outer end of the limiting post 20. The connecting block 15 is located between the corresponding radially extending edge 21 and the left or right side wall of the rear part of the wire drawing machine host 100, making it difficult for the connecting block 15 to detach from the limiting post 20, thus achieving a firm connection.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
