Description

Technical Field

[0001] This invention relates to the field of strip processing technology, and more specifically to a strip pulling mechanism. Background Technology

[0002] A progressive die consists of multiple stations, each completing a series of different stamping processes sequentially after one stroke of the press. After one stroke, the strip is fed at a fixed pitch. However, the rapid progressive feeding method of the strip makes it prone to breakage. If breakage occurs during stamping, it will affect the quality of the stamped product. Breakage of the edge material after stamping will directly affect the winding of the edge material, making edge material recycling more complicated and requiring unnecessary manpower.

[0003] Chinese Patent No. CN207086675U discloses a continuous stamping device for mobile phone card trays. This technical solution solves the above-mentioned technical problems by first heating the strip to improve its ductility before winding it up. However, due to the increased ductility of the strip, it is easy for the strip to deform during the pulling process, which affects the accurate feeding of the strip at a fixed step distance. Moreover, the parts on the strip become relatively soft after being heated, which is not conducive to stamping. Summary of the Invention

[0004] 1. The technical problem that the invention aims to solve

[0005] The purpose of this invention is to solve the technical problems existing in the prior art and provide a strip pulling mechanism that can prevent the heat of the rear end of the strip from being transferred to the front end, keep the temperature of the front end of the strip at a low value, make it hard, not easy to deform, facilitate stamping, and effectively prevent the deformation of the strip during the pulling process, ensuring the accuracy of the stamping position of the strip.

[0006] 2. Technical Solution

[0007] To solve the above problems, the technical solution provided by the present invention is as follows:

[0008] A material feeding mechanism includes a feeding mechanism, a cooling mechanism, a heating mechanism, and a winding mechanism arranged sequentially along the feeding direction of the material belt. The feeding mechanism includes a base; a movable block movably connected to the base; and a control structure for controlling the movable block to move back and forth along the feeding direction of the material belt. Two finger cylinders are symmetrically arranged at both ends of the movable block, and the clamping parts of the two finger cylinders are arranged opposite to each other.

[0009] Optionally, the control structure includes a guide rod, which is arranged along the feeding direction of the material belt and connected to the base; and several cylinders, which are respectively arranged on both sides of the movable block.

[0010] Optionally, the refrigeration mechanism includes a cold box, which is equipped with a refrigeration module and a material belt refrigeration channel.

[0011] Optionally, the heating mechanism includes a water tank filled with hot water, and a first pressure roller is provided inside the water tank, the first pressure roller being immersed in the hot water.

[0012] Optionally, the water tank is further provided with a second pressure roller, which is immersed in hot water. The first pressure roller and the second pressure roller abut against each other to form a material strip flattening channel.

[0013] Optionally, a feeding roller is provided on the base at the rear side of the refrigeration mechanism. The two ends of the feeding roller are connected to bearing seats, which are connected to the base. The feeding roller is hollow to form a hot water channel. It also includes a hot water pipe for connecting the feeding roller and the water tank.

[0014] Optionally, the winding mechanism includes a winding seat and a winding roller mounted on the winding seat, wherein the upper end face of the winding seat is an inclined surface that is inclined toward the water tank.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0017] The material pulling mechanism pulls the material strip by moving the movable block back and forth in conjunction with the finger cylinder. The cooling mechanism prevents heat from the rear end of the material strip from being transferred to the front end, keeping the front end temperature low, resulting in high hardness, resistance to deformation, and easy stamping. It also effectively prevents deformation of the material strip during the pulling process, ensuring accurate stamping position. By heating the rear end of the material strip, its ductility is improved, making it less prone to breakage during winding, ensuring continuous winding, and resulting in tighter bonding between layers. The resulting coil is smaller and less loose. Attached Figure Description

[0023] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0024] Combined with appendix Figure 1 This embodiment of a strip feeding mechanism includes a feeding mechanism 1, a cooling mechanism 2, a heating mechanism 3, and a winding mechanism 4 arranged sequentially along the strip feeding direction. When the stamped strip is wound up, it passes through the feeding mechanism 1, cooling mechanism 2, heating mechanism 3, and winding mechanism 4 in sequence. The cooling mechanism 2 is used to cool the strip, and the heating mechanism 3 is used to heat the strip. The feeding mechanism 1 includes a base 11; a movable block 12 movably connected to the base 11, which can slide relative to the base 11; and a control structure for controlling the movable block 12 to move back and forth along the strip feeding direction. Two finger cylinders 13 are symmetrically arranged at both ends of the movable block 12, with their clamping parts facing each other and cooperating to clamp both sides of the strip.

[0025] The material pulling mechanism of this strip achieves the pulling action of the strip by the back and forth movement of the movable block 12 and the cooperation of the finger cylinder 13. The cooling mechanism 2 can prevent the heat of the rear end of the strip from being transferred to the front end of the strip, so that the temperature of the front end of the strip is kept at a low value, the hardness is high, it is not easy to deform, and it is easy to stamp and form. It can also effectively prevent the deformation of the strip during the pulling process and ensure the accuracy of the stamping position of the strip. By heating the rear end of the strip, the extensibility of the rear end of the strip is improved, and it is not easy to break during the winding process, ensuring the continuous winding of the strip. Moreover, the adhesion between the layers is tighter, and the resulting roll is smaller and less loose.

[0026] As an optional embodiment of the present invention, the control structure includes a guide rod 14, which is arranged along the feeding direction of the material strip and connected to the base 11. The movable block 12 is sleeved on the guide rod 14, and the two ends of the guide rod 14 are connected to connecting seats, which are fixed to the base 11. Several cylinders 15 are respectively arranged on both sides of the movable block 12. In this embodiment, a total of four cylinders 15 are arranged on both sides of the movable block 12. The purpose of moving the movable block 12 is achieved by the extension and retraction of the cylinders 15. When one cylinder extends to push the movable block 12, the other cylinder retracts to limit the movement distance of the movable block 12. Through the linkage of the cylinders 15 on both sides, the movement distance of the movable block 12 can be effectively guaranteed, thereby facilitating the pulling distance of the material strip.

[0027] As an optional embodiment of the present invention, the refrigeration mechanism 2 includes a cold box 21, which is mounted on the base 11. The cold box 21 is provided with a refrigeration module and a material strip refrigeration channel 22. After passing through the material strip refrigeration channel 22, the material strip enters the heating mechanism 3. The refrigeration module includes a cold air blower or a cooler for providing cooling capacity to the material strip refrigeration channel 22. When the hot end of the material strip reaches the position of the refrigeration mechanism, it cannot continue to be transmitted forward, thereby achieving the purpose of heat insulation.

[0028] As an optional embodiment of the present invention, the heating mechanism 3 includes a water tank 31 filled with hot water. The water tank 31 may also be equipped with an electric heating wire or electric heating rod for heating the hot water. The water tank 31 is provided with a first pressure roller 32, which is immersed in the hot water. The material strip passes under the first pressure roller 32 to ensure that the material strip is completely immersed in the hot water. In this embodiment, heating the material strip with hot water can effectively increase the heat exchange area and ensure the heating speed of the material strip, especially when there are many gaps in the material strip after stamping.

[0029] As an optional embodiment of the present invention, the water tank 31 is further provided with a second pressure roller 33, which is located below the first pressure roller 32. The second pressure roller 33 is immersed in hot water. The first pressure roller 32 and the second pressure roller 33 abut against each other to form a material strip flattening channel. When the material strip passes through the material strip flattening channel, it is flattened under the squeezing action of the first pressure roller 32 and the second pressure roller 33, which prevents the burrs on the material strip from protruding outward and affecting the winding effect. At the same time, in this embodiment, the method of heating before flattening can ensure the flattening effect of the material strip. If a heating plate is used, not only is the heating effect poor, but the flattening effect will also be greatly reduced because both are flattening before heating methods.

[0030] As an optional embodiment of the present invention, the first pressure roller 32 and the second pressure roller 33 can be rotated by a motor.

[0031] As an optional embodiment of the present invention, a feeding roller 5 is provided on the base 11 at the rear side of the refrigeration mechanism 2. The two ends of the feeding roller 5 are connected to bearing seats 6, which are connected to the base 11. The feeding roller 5 is hollow inside to form a hot water channel. The bearing seats 6 are provided with an inlet and a outlet communicating with the hot water channel. It also includes a hot water pipe 7 for connecting the feeding roller 5 and the water tank 31. The hot water pipe 7 includes an inlet pipe connected to the inlet and a outlet pipe connected to the outlet. A water pump is provided on the inlet pipe. By pumping hot water into the feeding roller 5, preheating can be achieved when the material belt passes through the feeding roller 5, avoiding deformation, cracking, breakage, etc. of the low-temperature part of the material belt directly entering the hot water.

[0032] As an optional embodiment of the present invention, the surface of the feeding roller 5 is provided with a thermally conductive silicone layer.

[0033] As an optional embodiment of the present invention, the winding mechanism 4 includes a winding base 41 and a winding roller 42 mounted on the winding base 41. The winding roller 42 is controlled to rotate by a motor. During winding, the front end of the material strip is held by the finger cylinder 13. The material strip is tensioned and deformed under the action of the winding roller 42 to ensure that the material strip is tightly wound on the winding roller 42. At the same time, it can also prevent the stamping position of the material strip from being pulled during the winding process.

[0034] As an optional embodiment of the present invention, the upper end face of the winding seat 41 is inclined towards the water tank 31 so that water droplets on the surface of the material belt can flow back into the water tank 31 for reuse.

[0035] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
