Description

Technical Field

[0001] The present invention relates to the field of extrusion molding equipment, and particularly relates to a production and processing equipment for arc-shaped metal signs. Background Art

[0002] When bending a metal sign, a hand-cranked rolling machine is usually used. The rolling component of the hand-cranked rolling machine consists of three rolling rollers arranged in a triangular pattern. One end of the metal sign is fed between the rolling rollers arranged in a triangular pattern, and the handle is manually shaken to make the rolling rollers rotate, so that the metal sign can be pulled between the rolling rollers and bent into shape. When the bent arc of the formed metal sign tends to be circular, it will be wrapped around the rolling rollers of the rolling machine. At this time, the fixing frame on one side of the rolling roller needs to be removed in order to take out the metal sign from one side while ensuring the shape of the metal sign. When bending the next metal sign, the removed fixing frame needs to be reinstalled to ensure the stable support on both sides of the rolling roller. Therefore, the blanking process of the metal sign is cumbersome, affecting the overall processing efficiency. Summary of the Invention

[0029] It further includes a slider 3, a second side plate 4, a pressure roller 5, a C-shaped ring 6, a circular ring sleeve 7, a hand-crank driving assembly and an adjusting assembly; a sliding groove 101 is provided on each side of the base 1; a slider 3 in an L shape is slidably connected in each sliding groove 101; the horizontal side of the slider 3 is located in the sliding groove 101; a second side plate 4 is rotatably connected between the vertical sides of the two sliders 3; three pressure rollers 5 arranged in a triangular pattern are rotatably connected to the first side plate 2; a connecting shaft 501 is fixedly connected to each pressure roller 5; all the connecting shafts 501 are rotatably connected to the first side plate 2; all the pressure rollers 5 are jointly connected to a hand-crank driving assembly; the hand-crank driving assembly drives the pressure rollers 5 to rotate; three C-shaped rings 6 arranged in a triangular pattern are connected to the second side plate 4; the openings of the three C-shaped rings 6 face each other; a circular ring sleeve 7 is rotatably connected to each C-shaped ring 6 in an embedded manner; there is a clearance fit between the circular ring sleeve 7 and the pressure roller 5; an adjusting assembly is connected to the first side plate 2 and the second side plate 4.

[0030] The hand-crank driving assembly includes a crank handle 21, a spur gear 22 and an intermediate gear 23; a crank handle 21 is fixedly connected to one of the connecting shafts 501 located below; a spur gear 22 is fixedly connected to each of the two connecting shafts 501 located below; an intermediate gear 23 is rotatably connected to the first side plate 2; the intermediate gear 23 meshes with the two spur gears 22.

[0031] The adjusting assembly includes a first threaded rod 201, a first adjusting block 202, a second threaded rod 401 and a second adjusting block 402; the first threaded rod 201 is threadedly connected to the first side plate 2; the bottom end of the first threaded rod 201 is fixedly connected to the first adjusting block 202; the first adjusting block 202 is slidably connected to the first side plate 2; the first adjusting block 202 is rotatably connected to the connecting shaft 501 located above; the second threaded rod 401 is threadedly connected to the second side plate 4; the bottom end of the second threaded rod 401 is fixedly connected to the second adjusting block 402; the second adjusting block 402 is slidably connected to the second side plate 4; the second adjusting block 402 is fixedly connected to the upper C-shaped ring 6.

[0032] A rubber sleeve is provided on the holding part of the crank handle 21 to increase the comfort and friction of the user's grip.

[0033] The circular ring sleeve 7 and the C-shaped ring 6 are detachably connected, which is convenient for the user to add lubricating oil between the C-shaped ring 6 and the circular ring sleeve 7 to ensure the smooth rotation of the circular ring sleeve 7.

[0034] The side of the circular ring sleeve 7 close to the pressure roller 5 is funnel-shaped, which is convenient for the pressure roller 5 to be inserted into the circular ring sleeve 7.

[0035] Scales are provided at the sliding groove 101, which is convenient for the user to judge the relative position of the slider 3 and the sliding groove 101.

[0036] The base 1 is made of cast iron, so that the weight of the present invention is concentrated at the lower part, improving the use stability.

[0037] Before using the present invention, the user rotates the first threaded rod 201 and the second threaded rod 401 to drive the first adjusting block 202 and the second adjusting block 402 to move up and down. The first adjusting block 202 and the second adjusting block 402 drive the upper connecting shaft 501, the C-shaped ring 6 and the ring sleeve 7 to move up and down, so as to adjust the distance between the upper pressing roller 5 and the two lower pressing rollers 5, and to adjust the bending arc of the present invention for the metal sign.

[0038] When performing the bending work, the user inserts the metal sign to be bent into the gap between the upper pressing roller 5 and the two lower pressing rollers 5. Then, the user holds and rotates the crank 21 with one hand. The crank 21 drives the corresponding connecting shaft 501 to rotate. The connecting shaft 501 drives the corresponding spur gear 22 to rotate. The spur gear 22 drives the intermediate gear 23 to rotate. The intermediate gear 23 drives another spur gear 22 to rotate and the corresponding pressing roller 5 and connecting shaft 501 to rotate. At this time, the two lower pressing rollers 5 rotate in the same direction, pulling the metal sign into the space between the three pressing rollers 5 for bending work; Figure 1 Taking [reference benchmark], the side plate one 2 is on the right side and the side plate two 4 is on the left side. After the metal sign is bent and formed, the user pulls the side plate two 4 to the left. The side plate two 4 drives the slider 3 to move leftward in the sliding groove 101 until the ring sleeve 7 and the pressing roller 5 are separated. Then, as Figure 6 shown, the user flips the side plate two 4 downward so that it does not block the left side of the pressing roller 5. Then, the user slides the formed metal sign out from between the three pressing rollers 5 from right to left to remove the metal sign; then the user flips up the side plate two 4 again and pushes the side plate two 4 and the slider 3 back to the right (the user can judge the relative position of the slider 3 and the sliding groove 101 according to the scale set at the sliding groove 101 so that the side plate two 4 returns to the correct position), so that the ring sleeve 7 and the pressing roller 5 are butted. The ring sleeve 7 supports and limits the left side of the pressing roller 5 to prevent the left side of the three pressing rollers 5 from shifting, resulting in different gap sizes between the left and right sides and affecting the bending quality of the metal sign; thus, compared with the prior art, the present invention can quickly separate the ring sleeve 7 from the pressing roller 5 by moving the side plate two 4 a short distance, and flip the side plate two 4 downward to avoid it, so as to quickly take out the formed metal sign from between the pressing rollers 5. Then, the side plate two 4 is flipped and translated back to its original position, and the ring sleeve 7 is re-connected with the pressing roller 5 for limiting. The operation is fast and convenient for blanking and quickly performing the bending work on the next metal sign.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, as Figures 1-3 、 Figure 8 and Figure 9As shown, it further includes an extension block 31; the lower side of the base 1 is slidably connected with the extension block 31; two moving grooves 3101 are formed on the extension block 31; the horizontal side of the slider 3 slides in the adjacent moving grooves 3101; the pressing roller 5 is composed of a head section 51, an extended section 52 and a tail section 53; the head section 51, the extended section 52 and the tail section 53 are threadedly connected, and by increasing or decreasing the number of the extended sections 52, the overall length of the pressing roller 5 is changed.

[0041] The length of the pressing roller 5 is limited, and the sizes of the metal nameplates to be bent are different. In order to adapt to the bending work of larger-sized metal nameplates, at this time, the user pushes the second side plate 4 to the left, driving the slider 3 to move to the left in the sliding groove 101 and the moving groove 3101. After the slider 3 contacts the left side wall of the moving groove 3101, it will push the extension block 31 to move to the left and extend out of the base 1, thereby extending the distance between the first side plate 2 and the second side plate 4, as Figure 9 shown; then the user unscrews the tail section 53 from the extended section 52, and according to the length requirement, a corresponding number of extended sections 52 are newly added to the left side of the original extended section 52. Then the tail section 53 and the newly added extended section 52 are screwed together on the left side to form a lengthened complete pressing roller 5. Then the user pushes the second side plate 4 to the right, so that the ring sleeve 7 is docked with the lengthened pressing roller 5 to provide limit support for its left side, thereby completing the lengthening of the pressing roller 5 to adapt to larger-sized metal nameplates.

[0042] Embodiment 3

[0043] On the basis of Embodiment 1 and Embodiment 2, as Figures 1-3 and Figure 6 shown, it further includes an upper limit plate 41 and a lower limit plate 42; an upper limit plate 41 and a lower limit plate 42 are respectively connected to the opposite surfaces of the first side plate 2 and the second side plate 4; the two upper limit plates 41 are respectively fixedly connected to the corresponding adjusting block one 202 and adjusting block two 402; a limit groove 43 is formed between the upper limit plate 41 and the lower limit plate 42; the limit groove 43 aligns with the middle gaps of the three pressing rollers 5 arranged in a triangular pattern.

[0044] The hand-cranked rolling machine is small in volume and can be conveniently carried to different working locations to quickly start work on-site. After use, it can be easily stored and will not occupy valuable working areas for a long time; when using the present invention to bend a metal nameplate, the user needs to hold the metal nameplate with one hand and turn the crank 21 to drive the pressing roller 5 to rotate, and there is no free hand to stabilize the base 1. Moreover, the user's force is concentrated on one side of the crank 21, and it is very easy for the present invention to tilt or move to the side of the crank 21 during use, resulting in poor stability; therefore, the upper limit plate 41 and the lower limit plate 42 are provided to assist in limiting the metal nameplate, allowing the user to free one hand to fix the base 1 during the bending process. The specific process is as follows:

[0045] The user adjusts the distance between the first side plate 2 and the second side plate 4 according to the size of the metal sign, so that the distance between the first side plate 2 and the second side plate 4 is the same as the size of the metal sign. Then, one end of the metal sign is inserted between the three pressure rollers 5, and the left and right sides of the metal sign are respectively located in the limit grooves 43, and are limited and guided between the three pressure rollers 5 by the upper limit plate 41 and the lower limit plate 42. After that, the user can release the metal sign, fix the base 1 with one hand, and turn the crank 21 with the other hand. The three pressure rollers 5 rotate to pull the metal sign between the three pressure rollers 5 to complete the bending work (when slipping occurs, the user can use their hand to assist in pushing the metal sign). Therefore, during the bending process, the user does not need to hold the metal sign for positioning, and can free up a hand to fix the base 1 to prevent the present invention from tilting or moving towards the side of the crank 21.
