Background

The drawbench is also called a cold drawing machine, and can be classified into a chain type, a hydraulic transmission type, a rack type, a screw type, and the like, according to a transmission mode.

In a chain type bar drawing machine, as shown in fig. 1 and 4, a traction trolley is supported by two cross beams and is driven by a power unit through a chain, so that the traction trolley runs along guide rails on the cross beams. The chain is hooked by the traction trolley through the hook, and in order to keep the chain at a sufficient tension degree, the cylinder is arranged between the hook and the traction trolley, so that the chain positioned at the front part of the traction trolley (taking the advancing direction of the trolley during running as the front) is in an inclined suspension state in the actual running process. When the traction trolley pulls the bar stock out of the wire drawing die, the chain is instantaneously separated from the hook of the traction trolley under the action of inertia due to sudden force loss of the bar stock. In the process of chain separation, the chain can collide with the longitudinal beam of the frame body of the strip drawing machine under the action of gravity. Because the weight of the chain in the strip drawing machine is large and can reach 70 kilograms per meter, the impact sound of falling metal is very large, serious noise pollution is generated, and the hearing of workers is easily damaged.

Detailed Description

For convenience of description, the forward direction of the tractor 2 when running under load is defined as the forward direction.

In order to facilitate understanding of the present solution, a brief description will now be made of a partial structure of the slitter. As shown in fig. 1 and 2, the stripping machine comprises a stripping machine frame body 1, the stripping machine frame body 1 comprises two cross beams 11, a plurality of longitudinal beams 12 are uniformly distributed between the two cross beams 11 along the length direction of the cross beams 11 in a welding mode, and the cross beams 11 and the longitudinal beams 12 form a main frame structure of the stripping machine frame body 1. The front end of the frame body 1 of the stripping machine is provided with a power unit 3, and the power unit 3 drives a traction trolley 2 to move forwards along a cross beam 11 through a chain 4, so that a bar is pulled out of a wire drawing die. The traction trolley 2 stretches across the upper part of the stripping machine frame body 1, and a trolley walking wheel train 21 of the traction trolley 2 can move back and forth along a guide rail on a cross beam 11 of the stripping machine frame body 1. The chain 4 is positioned between the traction trolley 2 and the frame body 1 of the stripping machine and is positioned in the middle of the traction trolley 2. The front part of the traction trolley 2 is provided with a hook 22, and the hook 22 is hooked on a certain chain link of the chain 4, so that the traction trolley 2 is driven to move forwards through the chain 4.

As shown in fig. 1 and 2, a stripping and noise reduction mechanism applied to a stripping machine comprises a plurality of groups of elastic support assemblies 5 arranged at the front end of a frame body 1 of the stripping machine. As a specific implementation manner, three sets of elastic supporting components 5 are disposed at the front end of the frame body 1 of the slitter in the embodiment. And the elastic support assembly 5 is arranged between two adjacent longitudinal beams 12.

Here, the number of the elastic support members 5 can be adjusted according to the actual situation, mainly according to the length of the processed bar, so as to ensure that the elastic support members 5 are arranged at the lower part of the chain 4 when the chain is unhooked.

As shown in fig. 4, 5 and 7, the elastic support assembly 5 includes a bottom plate 51, a support frame 52 is disposed on the bottom plate 51, a roller 53 is disposed above the support frame 52, and the roller 53 is rotatably connected to an ear plate 521 on the support frame 52 through a pin 54. At least two mandrels 522 are fixedly arranged below the support frame 52 in a welding mode, and through holes for accommodating the mandrels 522 are formed in the bottom plate 51. As a specific embodiment, the support frame 52 described in this embodiment is provided with three mandrels 522. The mandrel 522 extends through the bottom plate 51 to below the bottom plate 51. A pressure spring 55 is sleeved on the mandrel 522 between the support frame 52 and the bottom plate 51.

As shown in fig. 3, in the free state, the distance M between the upper side surface of the roller 53 and the upper end surface of the side member 12 is greater than 50 mm.

In this embodiment, the front and rear ends of the bottom plate 51 are fixedly connected to the longitudinal beams 12 by welding.

Further, as shown in fig. 5, since the chain 4 is still in the running state during the falling, the impact force on the elastic support assembly 5 is obliquely forward and downward during the falling, so that the two rollers 53 are impacted by the falling of the chain and simultaneously reduce the friction of the forward running of the chain, which is also the reason for arranging the rollers 53.

For this purpose, as shown in fig. 5 and 7, a pulling brace 58 is disposed behind the supporting frame 52, a front end of the pulling brace 58 is fixedly connected with the supporting frame 52 by welding, and a rear end of the pulling brace 58 is hinged to the bottom plate 51.

Further, as shown in fig. 4, two rollers 53 are disposed on the supporting frame 52 along the left-right direction, and the rollers 53 are rotatably connected to the ear plate 521 on the supporting frame 52 through a pin 54. The two rollers 53 correspond to friction surfaces on the left and right sides of the chain 4, respectively.

The arrangement mainly considers that the roller 53 can not generate the phenomenon of surface abrasion with the bottom of the chain due to rotation, and the maintenance is reduced in the using process.

Further, as shown in fig. 6, a plurality of height adjusting pads 56 are disposed on the mandrel 522 between the compression spring 55 and the bottom plate 51. The number of the height adjusting pads 56 can be increased or decreased according to the requirement, and when the height adjusting device is used, the number of the height adjusting pads 56 is increased or decreased, so that the roller 53 can reach the required height and the equal height of a plurality of supporting frames can be adjusted.

Further, as shown in fig. 8, since the supporting frame 52 with the spindle 522 thereon rotates around the hinge point at the rear end of the pulling-up frame 58 during the actual operation, the spindle 522 is inclined in the compressed state, and in order to ensure uniform force application of the compression spring 55, as shown in fig. 6, a tapered pad 57 is disposed on the spindle 522 between the bottom plate 51 and the lowermost height adjusting pad 56.
