Freely displaceable structure of grooving machine

Abstract

The utility model relates to the technical field of groove pressing machines, in particular to a free-displacement structure of a groove pressing machine, and aims to solve the problems that in the prior art, the groove pressing machine moves only through universal wheels, so that the groove pressing machine is prone to displacement due to external force collision and the like in the using process, and the groove pressing machine cannot move freely. The grooving machine comprises a base and a grooving machine body fixed to the upper side of the base. When the notching machine body needs to be moved, the universal wheels are pushed through the tilting rods, so that the universal wheels make contact with the ground, then the base is supported through the tilting rods, and therefore the notching machine body moves through the base and the universal wheels, and when the notching machine body is not used, the stability of the notching machine body during use is improved by retracting the universal wheels; and the probability that the pipe machining is influenced due to insufficient stability caused by external force when the groove pressing machine body is used is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of slot pressing machines, and more specifically to a freely displaceable structure of a slot pressing machine. Background Art

[0002] Grooving machine (also called pipe bending machine) is a pipe bending machine used to cold bend or roll metal pipes into different shapes. Grooving machine locally squeezes a part of the pipe to bend the pipe to form the desired shape. Grooving machine is suitable for pipes of various diameters and wall thicknesses, and can process straight, curved, twisted and other curved pipes.

[0003] In order to facilitate movement during use, the groove pressing machine in the prior art will be equipped with universal wheels with a self-locking function at the bottom. Although the universal wheels make the groove pressing machine easy to move, the stability of the self-locking universal wheels will be affected under different ground conditions, especially on uneven or low-friction ground. Therefore, the self-locking universal wheels cannot provide sufficient stability for the groove pressing machine, resulting in the groove pressing machine being easily displaced due to external force collision and other reasons during use, thereby affecting the processing effect of the groove pressing machine when processing pipes.

A plurality of limiting grooves 9 are provided which penetrate the limiting grooves 9, and a tilting rod 10 is provided on the inner wall of the limiting grooves 9, one end of the tilting rod 10 extends into the base 1, and the other end of the tilting rod 10 extends to the outside of the base 1 and is provided with a universal wheel 11; when the groove pressing machine body 2 needs to be moved, the universal wheel 11 is pushed by the tilting rod 10, so that the universal wheel 11 contacts the ground and then the base 1 is propped up by the tilting rod 10, so that the groove pressing machine body 2 is moved through the base 1 and the universal wheel 11, and when not in use, the universal wheel 11 is folded up to increase its stability during use, thereby reducing the probability of the problem that the groove pressing machine body 2 is insufficiently stable due to external force during use and affects the pipe processing.

[0022] Furthermore, the top inner wall of the base 1 is rotatably connected to a plurality of reciprocating screws 12, the outer wall of the reciprocating screw 12 is fixedly connected to a transmission gear 13, the bottom of the shuttle of the reciprocating screw 12 is fixedly connected to a pillar 14, and the pillar 14 sleeves the reciprocating screw 12, the other end of the pillar 14 passes through the bottom of the base 1, and its outer wall is slidably connected to the base 1 at the penetration thereof, the inner wall of the swivel 3 is fixedly connected to a plurality of evenly arranged inner ring teeth 15, and the inner ring teeth 15 can mesh with the gear teeth of the transmission gear 13 when the swivel 3 rotates; by automatically releasing and retracting the pillar 14 in the base 1 during the process of retracting and releasing the universal wheel 11, the pillar 14 in the base 1 can be automatically released and retracted, so that in this process, the pillar 14 can support the base 1, and the height of the base 1 can be controlled by releasing and retracting the pillar 14, so that the height of the groove pressing machine body 2 can be adjusted, so that the groove pressing machine body 2 can adapt to and process pipes of different sizes.

[0023] Furthermore, a foot pedal 16 is fixedly connected to one side of the rotating rod 5 located outside the base 1 ; by providing the foot pedal 16 , a worker can more conveniently control the folding and releasing of the universal wheel 11 by stepping on the foot pedal 16 .

[0024] Furthermore, an anti-wear tube 17 is sleeved on one side of the tilting rod 10 located inside the base 1 and is rotatably connected to the tilting rod 10, and when the linkage plate 4 rotates with the swivel ring 3, its outer wall will abut against the outer wall of the anti-wear tube 17; by providing the anti-wear tube 17, the linkage plate 4 does not directly contact the outer wall of the tilting rod 10, but instead abuts against the anti-wear tube 17 to make the anti-wear tube 17 rotate on the tilting rod 10, so that the linkage plate 4 pushes the tilting rod 10 through the anti-wear tube 17, thereby controlling the retraction and release of the universal wheel 11, thereby preventing the tilting rod 10 and the linkage plate 4 from being worn and stuck.

[0026] Furthermore, the bottom of the pillars 14 are fixedly connected with anti-skid pads 18; by providing the anti-skid pads 18, the anti-skid effect of the bottom of the pillars 14 and the ground is increased when supporting the base 1, thereby increasing the stability of the groove pressing machine body 2 when in use.

[0027] Working principle: This embodiment provides a freely displaceable structure of the slotting machine. When in use, the staff steps on the foot pedal 16, so that the foot pedal 16 drives the rotating rod 5 to rotate, and the rotating rod 5 is reset and rotated under its own torque, so that the rotating rod 5 is cyclically rotated and reset;

[0028] The rotating rod 5 will drive the first ratchet 6 to rotate and reset when rotating, and the ratchet is a one-way transmission structure, so the first ratchet 6 can only drive the second ratchet 7 to rotate when the rotating rod 5 rotates due to the pedal 16, so that the second ratchet 7 can only rotate in one direction, and the second ratchet 7 can only rotate in one direction and drive the rotating ring 3 to rotate in one direction through the outer ring teeth 8, and the rotating ring 3 will synchronously drive the linkage plate 4 and the inner ring teeth 15 to rotate together when rotating;

[0029] When the linkage plate 4 rotates, its outer wall will gradually fit with the anti-wear tube 17, and the anti-wear tube 17 will fit the tilting rod 10, so that the tilting rod 10 is pushed and drives the universal wheel 11 to move downward, and at this time, the inner ring gear 15 drives the transmission gear 13 to rotate, and the rotation of the transmission gear 13 drives the reciprocating screw rod 12 to rotate. It should be noted that the shuttle of the reciprocating screw rod 12 is fixedly connected to the pillar 14, so the shuttle of the reciprocating screw rod 12 will drive the pillar 14 to move upward and retract into the base 1, so that the base 1 is supported by the universal wheel 11, so that the groove pressing machine body 2 can move freely through the universal wheel 11;

[0030] Similarly, as the swivel ring 3 continues to rotate, the linkage plate 4 gradually loses contact with the anti-wear tube 17. At this time, the universal wheel 11 will be lifted upward under the action of the tilting rod 10. It should also be noted that the reciprocating screw 12 is a screw that can make the shuttle on it realize reciprocating motion without changing the rotation direction of the main shaft. Therefore, as the reciprocating screw 12 continues to rotate, the shuttle on the reciprocating screw 12 will push the support 14 out, so that the bottom of the support 14 contacts the ground to support the base 1, so that after the universal wheel 11 is retracted, the support 14 can provide more stable support for the groove pressing machine body 2, and by controlling the number of times the rotating rod 5 is stepped on, the distance that the reciprocating screw 12 drives the support 14 to move is controlled, thereby controlling the overall height of the groove pressing machine body 2.
