Description

Technical Field

[0001] The utility model relates to a device for quickly demoulding a pipe after bending and forming. Background Art

[0002] At present, the demoulding of the bending process of "￠14mm ball tube bending forming" with multiple bends and a bending angle of 180° is done by rotating the angle twice to avoid the mold and then demoulding.

[0003] After the normal bending of the ￠14mm ball tube is completed, the demoulding steps are as follows: the demoulding is completed in 3 steps: the tube tail rotates 55° once, the tube tail translates once, the tube tail rotates 90° upward again, avoids interference, and translates again to remove the tube.

[0004] The demoulding operation of the ￠14mm ball tube after bending 180° wastes a certain amount of waiting time and the gap at the material removal position is extremely narrow: the demoulding is not completely completed in one time after bending, and it needs to be rotated twice in space to have a demoulding gap. It takes about 3-5 seconds to complete the demoulding. Utility Model Content

[0005] In view of the above problems, the utility model provides a device for quickly demoulding a pipe after bending and forming, which effectively solves the problems pointed out in the background technology.

[0006] The technical solution adopted by the utility model is:

[0007] A device for quickly demoulding a pipe after bending and forming, comprising an upper wheel die and a lower wheel die, wherein a U-shaped die groove is arranged at the mold joint of the upper wheel die and the lower wheel die, wherein the upper half of the U-shaped die groove is located at the bottom edge of the upper wheel die, and the lower half is located at the top edge of the lower wheel die, and a tooth pattern area is arranged in the U-shaped die groove, wherein the upper wheel die is fixed on an upper die seat, wherein the upper die seat is moved up and down by an oil cylinder, and wherein the lower wheel die is fixed on a lower die seat.

[0008] Preferably, a first longitudinal positioning rod and a second longitudinal positioning rod are fixed to the bottom of the upper wheel mold, and a first positioning hole and a second positioning hole are opened on the top of the lower wheel mold, and the first positioning rod and the second positioning rod match the first positioning hole and the second positioning hole respectively.

[0009] The upper wheel mold and the lower wheel mold are accurately positioned when the mold is closed through the cooperation of the first positioning rod and the first positioning hole, and the second positioning rod and the second positioning hole, so as to ensure the bending effect.

[0010] Preferably, the lower die seat is fixed on the base, the cylinder seat of the oil cylinder is fixed on the top seat, the piston rod is fixed to the upper die seat, and the base and the top seat are fixedly connected by a bracket.

[0011] Preferably, the cross-section of the U-shaped die groove is semicircular.

[0012] The semicircular die groove can provide the best support for the ball tube and ensure the bending effect.

[0013] The utility model redesigns the bending wheel mold structure, splits the 180° bending closed wheel mold into a separate wheel mold, which is divided into an upper wheel mold and a lower wheel mold, and adds a base, a top seat and a bracket to improve the stability of the wheel mold for 180° bending. After bending and forming, the oil cylinder is opened, so that the upper wheel mold moves upward with the upper mold seat and separates from the lower wheel mold, so that the ball tube can be quickly separated and demolded, eliminating the steps of multiple rotations of the ball tube and improving the demolding efficiency.

[0014] The utility model can improve the clamping friction force by arranging the tooth pattern area in the U-shaped die groove.

[0015] The utility model changes the closed wheel mold into an upper and lower opening and closing wheel mold. The top seat, the base and the bracket form a separate structure, and the upper and lower wheel molds are opened and closed by the oil cylinder to ensure the inner roundness requirements and the outer diameter deformation of the ball tube. After bending 180 degrees, the traditional demoulding method is cancelled, and the ball tube can be demoulded by moving horizontally after lifting, which greatly improves the demoulding efficiency.

[0024] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0025] like Figure 1As shown, a device for quickly demolding a pipe after bending and forming comprises an upper wheel die 1 and a lower wheel die 2, wherein a U-shaped die groove 3 is provided at the mold joint of the upper wheel die 1 and the lower wheel die 2, wherein the upper half of the U-shaped die groove 3 is located at the bottom edge of the upper wheel die 1, and the lower half is located at the top edge of the lower wheel die 2, and a tooth pattern area 4 is provided in the U-shaped die groove 3, the upper wheel die 1 is fixed on an upper die base 5, the upper die base 5 is moved up and down by an oil cylinder 6, and the lower wheel die 2 is fixed on a lower die base 7.

[0026] A first longitudinal positioning rod 8 and a second longitudinal positioning rod 9 are fixed to the bottom of the upper wheel mold 1, and a first positioning hole 10 and a second positioning hole 11 are opened on the top of the lower wheel mold 2. The first positioning rod 8 and the second positioning rod 9 match the first positioning hole 10 and the second positioning hole 11 respectively.

[0027] The lower die seat 7 is fixed on the base 12 , the cylinder seat of the oil cylinder 6 is fixed on the top seat 13 , the piston rod is fixed to the upper die seat 5 , and the base 12 and the top seat 13 are fixedly connected via a bracket 14 .

[0028] The cross section of the U-shaped die groove 3 is semicircular.

[0029] The U-shaped die groove 3 of the utility model is used for the last bend of the ball tube. After the bending of the tube is completed, the upper wheel die 2 can be directly controlled by the oil cylinder 6 to move up and separate it from the lower wheel die 2, so that the ball tube can be quickly taken out.

[0030] The lower wheel mold 2 of the present invention also has a first-bend mold groove and a second-bend mold groove. Since its structure is the same as that of a conventional mold, the present invention will not be described in detail.

[0031] When the utility model is bending the tube, the upper wheel die 1 and the lower wheel die 2 are in a mold-closing state in the initial state by the action of the oil cylinder 6. When bending the tube, the tube is first placed in the first and second bends of the die grooves below the lower wheel die 2 for bending, and then placed in the U-shaped die groove 3 for the third bend. After the third bend is completed, the upper wheel die 2 can be controlled by the oil cylinder 6 to move up, so that the upper wheel die 1 is separated from the lower wheel die 2. Figure 2 As shown, finally the ball tube can be lifted and then moved horizontally to complete demoulding. The lifting and horizontal movement of the ball tube can be completed by a robot. Since it is relatively common for a robot to complete such actions, the utility model will not describe them in detail.

[0032] Finally, it should be noted that the above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by a person skilled in the art from the present invention should be considered as the protection scope of the present invention.
