TECHNICAL FIELD

[0002] In the machining process of automobile parts, circular or rectangular metal strips are often used as workpieces, which are machined into specific shapes to meet assembly requirements. By heating the local metal strip to a certain temperature, the yield strength of the heated area of the metal strip is reduced, avoiding cracks during the bending process of the metal strip under stress. The heated area of the metal strip can start plastic deformation under lower stress, and then obtain a specific product form.
[0003] In actual work process, metal strip is transported to high temperature treatment area as workpiece for local heating, and then moved to next process after heating process is completed. The processing method is to place the metal strip on the transfer steel belt for transportation, and then gradually clamp the metal strip by mechanical arm, and move the metal strip to high temperature treatment area for heating. After heating is completed, the metal strip is placed on the transfer steel belt by mechanical arm and transported to next process. Although this method has high intelligence, considering cost and large-scale production demand, the processing efficiency and benefit are not obvious.
[0004] After improvement, the metal strip is transported to heating area by transport steel belt for local heating, and then transported to next process by metal steel belt after heating. This method significantly increases processing efficiency, but still has many problems to be improved: on the one hand, due to the physical property change of the heated metal strip, the metal strip often slips on the transport steel belt, and local collision between metal strips occurs, which increases the risk of deformation of the heated area of the metal strip and increases the risk of surface defects of the metal strip. On the other hand, the transport posture of the metal strip on the transfer steel belt is not easy to limit, which causes the metal strip on the transfer steel belt to not correspond to the required heating area in the heating area. Therefore, how to better input the metal strip into the heating area for heating, and how to reduce the collision risk of the metal strip after heating from the transport belt to the next process are currently urgent.

[0027] The current carrier 1 is mainly the existing integrated carrier, and a heating device is pre-set on the carrier 1, and the heating device is generally a spray gun or a hollow electric heating furnace, so that the heating device heats the local metal strip by passing or penetrating through the heating device. Considering the original mechanical arm cooperation, the equipment cost is higher, and only one metal strip can be processed at a time, and the production capacity is easily dragged. Therefore, after improvement, a longer heating device is installed on the current carrier 1, so that the heating area is longer and can accommodate more metal strips. The production line has improved the grabbing head of the mechanical arm, and the efficiency is increased by increasing the number of metal strips heated at the same time, but the grabbing difficulty and the equipment stroke greatly occupy the factory space, so it is necessary to adjust the way of metal strip entering the heating area for heating and reduce the improvement cost.
[0028] Reference Figures 1 to 3 As shown in the figure, an embodiment of the utility model is a surrounding type processing support for part heat treatment, including carrier 1 and transfer steel belt 2, wherein the transfer steel belt 2 is a chain type steel belt made of existing high-temperature-resistant metal; the metal strip is transported to the heating area of the carrier 1 by the transfer steel belt 2; the metal strip is transported to the heating area C of the heating device of the carrier 1 by the transfer steel belt 2, the metal strip is controlled to enter the heating area C of the heating device in a stable posture, and the time of the metal strip passing through the heating area C is controlled to meet the heating time requirement of the metal strip.
[0029] Reference Figure 1 And Figure 6As shown, considering that the heating device matches the heating area position of the metal strip, the first end and the last end of the carrier 1 are respectively provided with a first transmission shaft 101 and a second transmission shaft 102, the first transmission shaft 101 and the second transmission shaft 102 are arranged at the same horizontal height, and the conveying steel belt 2 is sleeved on the first transmission shaft 101 and the second transmission shaft 102; wherein the first transmission shaft 101 and the second transmission shaft 102 are of the same specification, and the conveying steel belt 2 is circulated and rotated by the first transmission shaft 101 and the second transmission shaft 102. In addition, the first transmission shaft 101 and the second transmission shaft 102 are arranged at the same height, which can also ensure that the upper surface of the conveying steel belt 2 is on a machining horizontal plane corresponding to the heating area C of the carrier 1. The metal strip is horizontally moved to the heating area C by the conveying steel belt 2, and the local heating of the metal strip is completed by passing through the heating area C, so that the metal strip can be bent in the next process.

The movable piece 3 is provided with a limiting block 4, and a clamping gap is arranged between the adjacent two limiting blocks 4, and the metal strip is limited by the clamping gap; wherein the limiting block 4 is protruded on the movable piece 3, so that there are two protrusions between the two movable pieces 3, and the spacing between the limiting blocks 4 can be used to limit the metal strip.
[0031] Since the spacing between the limiting blocks 4 can limit the metal strip, in order to facilitate the metal to be separated from the limiting block 4 after being heated, a third transmission shaft 103 matched with the conveying steel belt 2 is arranged below the second transmission shaft 102, the third transmission shaft 103 is used to drive the conveying steel belt 2 to be inclined between the second transmission shaft 102 and the third transmission shaft 103 and form a blanking section; wherein the third transmission shaft 103 is arranged on an inclined track on the moving path of the conveying steel belt 2, so that the metal strip can be separated from the limiting block 4 during the movement of the limiting block 4 from the second transmission shaft 102 to the third transmission shaft 103. In order to ensure that the metal strip is completely separated, a stripping plate 5 is arranged on one side of the conveying steel belt 2, the height of the stripping plate 5 is between the second transmission shaft 102 and the third transmission shaft 103, and the stripping plate 5 is gradually inclined from top to bottom. If the metal strip on the limiting block 4 cannot be separated after passing through the second transmission shaft 102, as the limiting block 4 continues to move to the third transmission shaft 103, the metal strip will contact the stripping plate 5, at this time, the stripping plate 5 will resist the metal strip, and as the limiting block 4 continues to move to the third transmission shaft 103, the metal strip will be forced to separate from the limiting block 4.

[0033] In order to guarantee the cooperation of unhooking plate 5 and transfer steel band 2, the spacing between two transfer steel band 2 is greater than the length of above-mentioned unhooking plate 5, and unhooking plate 5 is placed between two transfer steel band 2, so that the movement of transfer steel band 2 is not influenced by unhooking plate 5, and unhooking plate 5 can also normally abut metal strip in the process that metal strip continues to move with transfer steel band 2.
[0034] Further technical solutions are, in order to optimize the stability of transfer steel band 2 moving on transmission shaft, the lower surface of the transfer steel band 2 is provided with a guide groove 201, the first transmission shaft 101, the second transmission shaft 102 and the third transmission shaft 103 are all provided with a guide wheel 105 matched with the guide groove 201, and the guide wheel 105 is used to extend into the guide groove 201 and apply a friction force to the transfer steel band 2 through the inner wall of the guide groove 201. The guide wheel 105 extends into the guide groove 201, which can provide stable support and guidance when the transfer steel band 2 moves, effectively reducing the shaking or deviation of the metal strip during transmission, ensuring the stability of the movement of the metal strip, and facilitating the heating of the metal strip in the heating area C.

When the transfer steel band 2 moves from the fourth transmission shaft 104 to the first transmission shaft 101, the movement path of the transfer steel band 2 is inclined, so as to move in an inclined state, and the inclined mode is convenient for observation, thereby facilitating the insertion of the metal strip. At the same time, the setting of the fourth transmission shaft 104 helps to maintain or increase the tension of the transfer steel band 2.
[0036] Further, reference Figure 2 and Figure 3As shown, the first transmission shaft, the second transmission shaft 102, the third transmission shaft 103 and the fourth transmission shaft 104 are provided with transmission wheels 106, the transmission belt 6 is sleeved on the transmission wheel 106, and the transmission belt 6 is used to drive the first transmission shaft, the second transmission shaft 102, the third transmission shaft 103 and the fourth transmission shaft 104 to rotate synchronously; wherein the first transmission shaft, the second transmission shaft 102, the third transmission shaft 103 and the fourth transmission shaft 104 are provided with driving motors.
