DETAILED DESCRIPTION

[0030] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Example

[0032] like Figure 1-7 As shown, a multi-pass continuous drawing device for a brass rod proposed by the utility model comprises a base 1, a first mold 5 mounted on the base 1, and a first feeding mechanism mounted on the base 1. A drawing mechanism mounted on the base 1. A bearing seat 101 is mounted on the base 1. When the brass rod is stretched, the brass rod is passed through the bearing seat 101. The first feeding mechanism comprises two first feeding hydraulic rods 201 fixedly mounted on the base 1, and a first clamping block 2 fixedly mounted on the output shafts of the two first feeding hydraulic rods 201. The drawing mechanism comprises a support plate 302 fixedly mounted on the ground, two drawing hydraulic rods 301 fixedly mounted on the support plate 302 and the base 1, and a second clamping block 3 fixedly mounted on the output shafts of the two drawing hydraulic rods 301. The first clamping mechanism is mounted on both the first clamping block 2 and the second clamping block 3. The first feeding hydraulic rod 201 can drive the first clamping block 2 to move, and the drawing hydraulic rod 301 can drive the second clamping block 3 to move. When the brass rod passes through the first die 5, after the brass rod is clamped by the first clamping block 2, the brass rod is passed through the first die 5 by the first feeding hydraulic rod 201, and then the brass rod passing through the first die 5 is clamped by the second clamping block 3, and then the brass rod is pulled out of the first die 5 by the pulling hydraulic rod 301, completing the first stretching of the brass rod.

[0033] The first clamping mechanism includes a first clamping hydraulic rod 4 fixedly mounted on both sides of the first clamping block 2 and the second clamping block 3, a clamping hole provided on the first clamping block 2 and the second clamping block 3, and two first clamping pieces 401 slidably mounted in the clamping holes. The first clamping pieces 401 correspond to and are fixedly connected with the first clamping hydraulic rod 4. When the brass rod is located inside the clamping hole, starting the first clamping hydraulic rod 4 can drive the first clamping piece 401 to clamp and fix the brass rod.

[0034] It also includes a feeding chute 6 arranged on the base 1. The brass rod after passing through the first mold 5 will enter the feeding chute 6, and the transfer pipe 601 fixedly installed on the base 1 and located below the feeding chute 6. The brass rod can enter the transfer pipe 601 through the feeding chute 6. The transfer drive mechanism is installed on both sides of the transfer pipe 601, and the transfer drive mechanism drives the brass rod in the transfer pipe 601 to move. The transfer drive mechanism includes a plurality of drive disks 602 rotatably installed on both sides of the transfer pipe 601, and a linkage belt 603 fixedly installed on the drive disks 602, wherein two drive disks 602 are fixedly installed with gears 604, the two gears 604 are meshed with each other, and the two gears 604 are located on both sides of the transfer pipe 601, and a motor seat 606 is fixedly installed on the ground, and a motor 605 is fixedly installed on the motor seat 606, and the output shaft of the motor 605 is fixedly connected to one of the gears 604. When the brass rod enters the transfer tube 601, it will be located between the multiple drive disks 602 on both sides. At this time, the motor 605 is started to drive one of the gears 604 to rotate, so that the two gears 604 can rotate in the opposite direction. The linkage belt 603 is used to drive the multiple drive disks 602 on both sides to rotate in the opposite direction. The friction between the brass rod and the drive disk 602 bracket can drive the brass rod to move inside the transfer tube 601.

[0035] The lifting mechanism is installed on one side of the transfer tube 601, and the lifting mechanism lifts the brass rod in the transfer tube 601. The lifting mechanism includes two lifting hydraulic rods 7 fixedly installed on the ground, and the lifting hydraulic rods 7 penetrate the transfer tube 601 and extend to the inside of the transfer tube 601. A support seat 701 is fixedly installed on the output shaft of the lifting hydraulic rod 7, and the support seat 701 is located inside the transfer tube 601. The transfer tube 601 is provided with a placement groove for holding the support seat 701. When the brass rod moves above the support seat 701, the lifting hydraulic rod 7 can be started to drive the support seat 701 to rise, and the support seat 701 can support the brass rod to rise, thereby moving the brass rod upward.

[0036] The second die 9 is installed on the base 1. The second feeding mechanism is installed on the base 1, and the second feeding mechanism inserts the brass rod on the lifting mechanism into the second die 9. The second feeding mechanism includes a slide bar 8 fixedly installed on the base 1, a third clamping block 801 slidably installed on the slide bar 8, and a second feeding hydraulic rod 802 fixedly installed on the third clamping block 801. The output shaft of the second feeding hydraulic rod 802 is fixedly connected to the base 1, and also includes a second clamping mechanism installed on the third clamping block 801. The brass rod lifted by the lifting mechanism will be clamped by the third clamping block 801, and under the action of the second feeding hydraulic rod 802, the third clamping block 801 drives the brass rod to move in the direction close to the second die, thereby driving the brass rod to pass through the second die 9. The brass rod passing through the second die 9 can be clamped again by the second clamping block 3, so that the brass rod can be stretched for a second time, and the brass rod can be stretched for a second time during the return process of the second clamping block 3, thereby improving the stretching efficiency.

[0037] The second clamping mechanism includes a notch provided on the third clamping block 801, two second clamping pieces 804 slidably mounted in the notch, and second clamping hydraulic rods 803 fixedly mounted on both sides of the third clamping block 801. The second clamping pieces 804 correspond to and are fixedly connected to the second clamping hydraulic rods 803. When the second clamping hydraulic rods 803 are activated, the second clamping pieces 804 can be driven to clamp and fix the brass rod.

[0038] It also includes an interception mechanism installed on the base 1, which controls whether the brass rod can pass through the feeding chute 6. The interception mechanism includes two electric push rods 10 fixedly installed on the base 1, and an interception rod 1001 fixedly installed on the output shaft of the electric push rod 10. The interception rod 1001 penetrates one side of the base 1 and extends to the inside of the feeding chute 6. When the brass rod is separated from the second clamping block 3 after the secondary stretching, the electric push rod 10 is started to move the interception rod 1001 to the inside of the feeding chute 6, thereby preventing the brass rod from falling into the transfer tube 601 again, so as to facilitate the removal of the brass rod after the stretching is completed.

[0039] Working principle: The first brass rod is passed through the bearing seat 101, and after being clamped by the first clamping block 2, the first brass rod is passed through the first mold 5 by the first feeding hydraulic rod 201, and then the first brass rod passing through the first mold 5 is clamped by the second clamping block 3, and then the first brass rod is pulled out of the first mold 5 by the pulling hydraulic rod 301, completing the first stretching of the first brass rod. At this time, the intercepting rod 1001 is located outside the feeding chute 6, and does not block the first brass rod. After the second clamping block 3 pulls the first brass rod out of the first mold, the first brass rod is canceled. The first brass rod will be clamped, and the first brass rod will enter the transfer tube 601, and then the hydraulic rod 301 will be pulled to drive the second clamping block 3 to return (Note: after the first pulling is completed, the return is empty, and the subsequent return is not empty) and the second brass rod will be stretched for the first time. At the same time, the brass rod entering the transfer tube 601 will be moved inside the transfer tube 601 through the driving disk 602. When the first brass rod moves to the top of the support seat 701, the lifting hydraulic rod 7 can be started to drive the support seat 701 to rise, and the support seat 701 can support the first brass rod to rise, thereby moving the first brass rod upward. At this time, the pulling hydraulic rod 301 drives the second clamping block 3 to pull the second brass rod out of the first mold 5. At this time, the first brass rod can be clamped by the third clamping block 801, and the first brass rod can be driven to pass through the second mold 9. The first brass rod passing through the second mold 9 can be clamped again by the second clamping block 3, so that the first brass rod can be stretched for the second time. When the first brass rod is pulled out of the second mold, the intercepting rod 1001 is moved to the inside of the discharge trough 6, so that the first brass rod stretched for the second time enters the inside of the transfer tube 601 again, which is convenient for taking out the first brass rod after the second stretching, and then the third brass rod can be stretched for the first time, and the second brass rod can be stretched for the second time during the return journey, and so on.
