[0003] Screws generally include a screw head, a screw shaft and a screw tail. In traditional screw processing, the screw head is first punched out, and then the threaded part is machined on the screw shaft through a turning process, and finally a thread rolling device is used to form high and low pitch threads on the outer peripheral wall of the threaded part blank.

[0004] When punching the screw end, the steel wire needs to be clamped and fixed first. The existing fixing device usually directly squeezes and fixes the steel wire when in use. After the punching is completed, the equipment cuts the steel wire, and the punched screw falls directly at the punching position. When the steel wire is continuously punched, the position of the screw cannot be automatically adjusted, and the punched screws need to be manually collected and cleaned. Even when the steel wire is sheared, if the steel wire is not completely cut off, the steel wire cannot be effectively separated from the screw, and the use effect is poor. Summary of the invention

DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, it is a structural diagram of a fixing device for screw processing provided by an embodiment of the present invention, comprising a workbench 1, two groups of relatively distributed vertical plates 2 are fixedly installed on the surface of the workbench 1, two groups of relatively distributed fixing blocks 3 are arranged between the two groups of the vertical plates 2 in the horizontal direction, the fixing blocks 3 are long strip structures, and the two opposite side walls of the two groups of fixing blocks 3 are respectively provided with fixing holes 31, the transverse cross-section of the fixing holes 31 is a semicircular structure, the bottom wall of the fixing block 31 is provided with an end slot 32 connected to the bottom end of the fixing hole 31, a shear block 33 is fixedly installed on the top of the fixing hole 31, the two groups of vertical plates 2 are jointly installed with a winding roller 5 located above the fixing block 3, the surface of the winding roller 5 is wound with steel wire, and a winding roller 5 connected to the fixing block 3 is arranged between the two groups of vertical plates 2. The fixed blocks 3 cooperate with each other in the telescopic component 6, and the telescopic component 6 is used to control the relative movement of the two groups of fixed blocks 3 in the horizontal direction. The surface of the workbench 1 is provided with a stamping part 7 located below the fixed block 3. The two groups of fixed blocks 3 are jointly provided with a clamping mechanism 8 that cooperates with the fixing hole 31. The clamping mechanism 8 includes a clamping bar 81, a positioning component 82 and an adjustment component 83. The positioning component 82 is located in one group of fixed blocks 3 and is connected to the clamping bar 81. The positioning component 82 is used to control the clamping bar 81 to be at the side wall of the fixing hole 31. The adjustment component 83 is located on the side wall of the other group of fixed blocks 3. The adjustment component 83 adjusts the relative position of the clamping bar 81 and the two groups of fixed blocks 3 by cooperating with the positioning component 82.

[0025] Initially, the two groups of fixed blocks 3 are separated from each other, and the positioning component 82 positions and fixes the clamping strip 81. At this time, the clamping strip 81 is at the side wall of one group of fixed blocks 3. The winding roller 5 rotates to release the steel wire, and the steel wire moves downward to between the two groups of fixed blocks 3. The telescopic component 6 controls the relative movement of the two groups of fixed blocks 3, so that the two groups of fixed blocks 3 fit each other, and the two groups of fixed holes 31 are combined to form a cylindrical structure. The steel wire is in the fixing hole 31, and the two groups of fixed blocks 3 squeeze and fix the steel wire. The shear block 33 at the top of the fixing hole 31 can automatically cut the steel wire. After the steel wire is fixed, the stamping part 7 can automatically stamp the steel wire in the end groove 32 of the bottom wall of the fixing block 3. After the stamping is completed, the telescopic component 6 controls the two groups of fixed blocks 3 to move back to back in the horizontal direction. The adjusting component 83 cooperates with the positioning component 82 to make the clamping strip 81 move in the opposite direction. 81 is connected as a whole with the group of fixed blocks 3 without the receiving groove 821. When the group of fixed blocks 3 without the receiving groove 821 moves to one side, it drives the clamping bar 81 to move synchronously. The clamping bar 81 cooperates with the fixed block 3 to continue to fix the stamped screw in the fixing hole 31. When the group of fixed blocks 3 without the receiving groove 821 moves to one side, it drives the screw to move synchronously. When the fixed block 3 moves to a certain distance, the adjustment component 83 releases the positioning of the clamping bar 81, and the positioning component 82 adjusts the position of the clamping bar 81 again. The clamping bar 81 moves back to the receiving groove 821. At this time, the screw falls from the side wall of the group of fixed blocks 3 without the receiving groove 821. At this time, the screw is far away from the stamping part 7. A corresponding collection box is placed on the surface of the workbench 1, and the screw falling from the fixing hole 31 can automatically fall into the collection box.

[0026] The two groups of shear blocks 33 cut the steel wire and then continuously punch out a plurality of screws. When the shear blocks 33 do not completely cut the steel wire, the steel wire is connected at the shearing position. When the two groups of fixing blocks 3 move away from each other after punching, the clamping strips 81 cooperate with the fixing blocks 3 to pull the screws to move synchronously, so that the screws can be pulled away from the shearing position, so that the screws are separated from the steel wire.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the telescopic assembly 6 includes two groups of relatively distributed side panels 61 fixedly installed between two groups of vertical panels 2, and the two groups of side panels 61 are jointly rotatably installed with two groups of relatively distributed threaded rods 62, and the threads on both sides of the threaded rods 62 are in opposite directions. The two groups of fixed blocks 3 are respectively spirally connected to the threaded rods 62, and a synchronous gear plate 63 is fixedly installed on the surface of the threaded rod 62. The two groups of synchronous gear plates 63 are jointly connected to a synchronous belt 64, and one end of a group of threaded rods 62 extends to the outside of the side panel 61 and is connected to a motor 65.

[0028] When in use, the motor 65 drives a group of threaded rods 62 to rotate, and the threaded rods 62 drive the synchronous gear plates 63 to rotate. The two groups of synchronous gear plates 63 cooperate with the synchronous belt 64 to drive the two groups of threaded rods 62 to rotate synchronously. The threaded rods 62 can push the two groups of fixing blocks 3 to move relative to each other between the two groups of vertical plates 2. When the two groups of fixing blocks 3 move relative to each other, the steel wire can be squeezed and fixed in the fixing hole 31. After the stamping is completed, the two groups of fixing blocks 3 move away from each other, and the stamped screws can be automatically taken out.

[0029] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the present invention, the stamping part 7 includes an electric telescopic rod 71 fixedly installed on the surface of the workbench 1, and a stamping plate 72 is fixedly installed on the telescopic end of the electric telescopic rod 71.

[0030] After the two sets of fixing blocks 3 squeeze and fix the steel wire through the fixing holes 31, the electric telescopic rod 71 pushes the stamping plate 72 to move upward. At this time, the stamping plate 72 can automatically stamp the cut steel wire at the end slot 32 to form the end head of the screw in the end slot 32.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, as a preferred embodiment of the present invention, the positioning assembly 82 includes a plurality of horizontal receiving grooves 821 formed on the side wall of a fixed block 3, the receiving grooves 821 are communicated with the fixing holes 31, the clamping strip 81 is located in the receiving grooves 821, and the fixed block 3 is provided with a plurality of telescopic cavities 822 at the same height as the receiving grooves 821, a connecting rod 824 is fixedly installed on the side wall of the clamping strip 81, one end of the connecting rod 824 away from the clamping strip 81 extends into the telescopic cavity 822 and is fixedly installed with a sliding block 823, and the sliding block 823 is slidably connected to the telescopic cavity 822.

[0032] Multiple groups of sliding blocks 823 cooperate with connecting rods 824 to position the clamping strip 81. The clamping strip 81 is in the receiving groove 821. When the two groups of fixed blocks 3 are squeezing and fixing the steel wire, the clamping strip 81 is in the receiving groove 821 and will not interfere with the entire extrusion process. When the group of fixed blocks 3 without the receiving groove 821 moves to one side after the stamping is completed, the adjusting component 83 controls the clamping strip 81 to move synchronously with it. The clamping strip 81 continues to squeeze and position the screw, and the screw moves synchronously with the fixed block 3. At this time, the sliding block 823 moves synchronously in the telescopic cavity 822. When the fixed block 3 moves to a certain distance, the adjusting component 83 releases the positioning of the clamping strip 81 at the side wall of the fixed block 3, and the adjusting component 83 pushes the sliding block 823 to move in the opposite direction in the telescopic cavity 822. The sliding block 823 cooperates with the connecting rod 824 to pull the clamping strip 81 to move in the opposite direction to the receiving groove 821.

[0033] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, as a preferred embodiment of the present invention, the adjustment component 83 includes an extrusion spring 832 fixedly installed at one end of the telescopic cavity 822 close to the storage groove 821, the extrusion spring 832 surrounds the outside of the connecting rod 824 and is connected to the sliding block 823, the clamping strip 81 is made of magnetic material, and the side wall of the group of fixed blocks 3 without the storage groove 821 is fixedly installed with a magnetic strip 831 that cooperates with the clamping strip 81.

[0034] When the two groups of fixed blocks 3 move relative to each other and fit together, the magnetic strip 831 at the side wall of the group of fixed blocks 3 without the receiving groove 821 is connected to the clamping strip 81 as a whole through the magnetic attraction. After the stamping is completed, the group of fixed blocks 3 without the receiving groove 821 moves to one side, and the magnetic strip 831 drives the clamping strip 81 to move synchronously with the fixed block 3. The clamping strip 81 cooperates with the fixed block 3, and the screw can be continuously positioned in the fixing hole 31. At this time, the sliding block 823 moves synchronously in the telescopic cavity 822 and squeezes the extrusion spring 832. After the two groups of fixed blocks 3 move back to back for a certain distance, the thrust of the extrusion spring 832 on the sliding block 823 is greater than the magnetic attraction of the magnetic strip 831 on the clamping strip 81, and the clamping strip 81 and the magnetic strip 831 are separated from each other, and the screw falls from the fixing hole 31. The extrusion spring 832 pushes the sliding block 823 to move in the opposite direction in the telescopic cavity 822 . The sliding block 823 cooperates with the connecting rod 824 to pull the clamping bar 81 to move in the opposite direction into the receiving groove 821 .

[0035] like Figure 1 , Figure 2 , Figure 5As shown, as a preferred embodiment of the present invention, the two side walls opposite to each other of the two groups of vertical plates 2 are respectively provided with limit grooves 9 distributed along the horizontal direction, and the limit blocks 10 are respectively fixedly installed at both ends of the fixed block 3, and the limit blocks 10 are slidably connected to the limit grooves 9.

[0036] When the two groups of fixed blocks 3 move relative to each other, the limiting block 10 moves synchronously in the limiting groove 9 . The limiting block 10 cooperates with the limiting groove 9 to effectively improve the stability of the fixed block 3 .

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, an electric heating plate 4 is fixedly installed between the two groups of vertical plates 2, and the electric heating plate 4 is located between the winding roller 5 and the fixed block 3. A straightening hole 41 is opened in the middle of the electric heating plate 4 with both ends passing through.

[0038] When the steel wire is released, it passes through the straightening hole 41, and the electric heating plate 4 heats the steel wire, so as to facilitate the straightening and stamping processing of the steel wire.

[0039] The working principle of the present invention is as follows: initially, the two groups of fixed blocks 3 are separated from each other, and the multiple groups of sliding blocks 823 cooperate with the connecting rod 824 to position the clamping bar 81, and the clamping bar 81 is in the receiving groove 821. The winding roller 5 rotates to release the steel wire, and the steel wire moves downward to between the two groups of fixed blocks 3. The motor 65 drives a group of threaded rods 62 to rotate, and the threaded rods 62 drive the synchronous toothed disc 63 to rotate. The two groups of synchronous toothed discs 63 cooperate with the synchronous belt 64 to drive the two groups of threaded rods 62 to rotate synchronously, and the threaded rods 62 can push The two groups of fixing blocks 3 move relative to each other between the two groups of vertical plates 2, so that the two groups of fixing blocks 3 fit each other, and the two groups of fixing holes 31 are combined to form a cylindrical structure. The steel wire is in the fixing hole 31, and the two groups of fixing blocks 3 squeeze and fix the steel wire. The shear block 33 at the top of the fixing hole 31 can automatically cut the steel wire. After the steel wire is fixed, the electric telescopic rod 71 pushes the stamping plate 72 to move upward. At this time, the stamping plate 72 can automatically stamp the cut steel wire at the end groove 32 to form the end head of the screw in the end groove 32.

[0040] After the stamping is completed, the two groups of fixed blocks 3 are controlled to move in opposite directions in the horizontal direction. The group of fixed blocks 3 without the receiving groove 821 moves to one side, and the magnetic strip 831 drives the clamping strip 81 to move synchronously with the fixed block 3. The clamping strip 81 cooperates with the fixed block 3 to continue to fix the stamped screw in the fixing hole 31. At this time, the sliding block 823 moves synchronously in the telescopic cavity 822 and squeezes the extrusion spring 832. When the group of fixed blocks 3 without the receiving groove 821 moves to one side, it drives the screw to move synchronously. When the fixed block 3 moves to a certain distance, the thrust of the extrusion spring 832 on the sliding block 823 is greater than the magnetic attraction of the magnetic strip 831 on the clamping strip 81, the clamping strip 81 and the magnetic strip 831 separate from each other, and the screw falls from the fixing hole 31. At this time, the screw is far away from the stamping part 7, and a corresponding collection box is placed on the surface of the workbench 1. The screw falling from the fixing hole 31 can automatically fall into the collection box. The extrusion spring 832 pushes the sliding block 823 to move in the opposite direction in the telescopic cavity 822 . The sliding block 823 cooperates with the connecting rod 824 to pull the clamping bar 81 to move in the opposite direction into the receiving groove 821 .

[0041] The two groups of shear blocks 33 cut the steel wire and then continuously punch out a plurality of screws. When the shear blocks 33 do not completely cut the steel wire, the steel wire is connected at the shearing position. When the two groups of fixing blocks 3 move away from each other after punching, the clamping strips 81 cooperate with the fixing blocks 3 to pull the screws to move synchronously, so that the screws can be pulled away from the shearing position, so that the screws are separated from the steel wire.

[0042] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
