Abstract
Description
Technical Field
[0001] This utility model relates to the field of stretching die technology, specifically a multi-station material-saving steel shell stretching die. Background Technology
[0002] In today's industrial manufacturing sector, steel shell products are widely used in numerous industries, such as electronic device housings, automotive parts, and protective covers for machinery, due to their excellent structural strength and protective performance. The production of steel shells typically involves forming them using stretching dies. The stretching process plays a crucial role in gradually transforming flat raw materials into steel shells with specific shapes and dimensions.
[0003] With the increasing demands for cost control and resource utilization efficiency in the manufacturing industry, saving raw materials during steel shell stretching has become a crucial issue that urgently needs to be addressed. Traditional steel shell stretching dies often result in material waste due to inaccurate raw material positioning during actual processing.
[0004] In multi-station steel shell stretching dies, raw materials need to undergo a series of processes, such as pre-stretching, multiple stretching, and shaping, through several different stations. However, due to the lack of an effective positioning mechanism, it is difficult to ensure that the raw material is centered when placed on the station. Once the initial position of the raw material deviates, for example, if it is biased to one side, the stress on the originally evenly distributed raw material will be uneven during the subsequent stretching process. In order to ensure the forming quality of the final steel shell product, that is, complete shape and dimensional compliance, more raw material must be used in areas with less material distribution to compensate for the local material shortage caused by the positional deviation. This results in the overall consumption of raw materials far exceeding the theoretical requirement, increasing production costs and contradicting the current development concept of green manufacturing and efficient resource utilization.
[0005] Based on this, a multi-station material-saving steel shell stretching die is introduced to improve the situation. Utility Model Content
[0006] The purpose of this invention is to provide a multi-station material-saving steel shell stretching die to solve the problems mentioned in the background art.
[0007] To achieve the above object, the utility model provides the following technical solution: A multi-station material-saving steel shell stretching die, including a workbench, on both the left and right sides of the top of the workbench are installed columns, on the top of the columns is installed a top plate, on the outer wall of the columns is sleeved a base, at the center position of the top of the top plate is screw-connected a hydraulic cylinder, the output end of the lower surface of the hydraulic cylinder penetrates the top plate and is fixedly connected to the top of the base, from left to right at the bottom of the base are installed brackets, at the bottom of the brackets is installed an upper die base, on both the left and right sides of the top of the workbench are provided bumps, from left to right on the top of the workbench are installed springs, at the top of the springs is installed a lower die base, at one end of the left and right sides of the bottom of the lower die base are installed limiting rods, and the other end of the limiting rods sequentially penetrates the springs and the outer wall of the workbench, on the inner circumference of the cavity of the lower die base are evenly arranged guide rods, on the outer wall of the guide rods is sleeved a base, on the outer circumference of the outer wall of the lower die base are screw-connected electric push rods, the inner output end of the electric push rods extends into the cavity of the lower die base and is fixedly connected to the outer wall of the base, at one end of the outer side of the base is installed a push rod, the other end of the push rod extends out of the outer wall of the lower die base and is installed a tactile sensor, and inside the tactile sensor is provided a top block.
[0008] Preferably, the upper die base and the bumps are matched and their positions correspond to each other.
[0009] Preferably, the limiting rod is in a "convex" shape.
[0010] Preferably, the number of the guide rods is three, and the three guide rods are distributed on the inner wall circumference of the lower die base at intervals of 120 degrees clockwise.
[0011] Preferably, the electric push rod and the tactile sensor are electrically connected to each other.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-station material-saving steel shell stretching die can push the base through an electric push rod to cause the push rod to move the tactile sensor and the push block together inward or outward. When multiple push blocks move inward simultaneously and abut against the outer wall of the raw material, the raw material is pushed to the center of the lower die base. At this time, the three tactile sensors will detect that all three push blocks are in contact with the raw material. The electric push rod will pull the base to cause the push rod to move the tactile sensor and the push block together outward, that is, the push block will move away from the lower die base, thereby completing the positioning of the raw material. By moving the upper die base downward and using it in conjunction with the protrusion, spring, lower die base and limiting rod, the positioned raw material can be subjected to conventional stretching processing. This device has an auxiliary positioning function, which can accurately position the raw material in the center of the station, effectively avoiding the need to rely on more raw material to make up for the local material shortage caused by deviation, saving production costs, conforming to the development concept of green manufacturing and efficient resource utilization, easy to use, highly practical, and meeting the needs of the current market.

At the bottom end of the base 4, brackets 6 are installed from left to right. At the bottom ends of the brackets 6, an upper die base 7 is installed. On both the left and right sides of the top end of the workbench 1, convex blocks 8 are provided. On the top end of the workbench 1, springs 9 are installed from left to right. At the top ends of the springs 9, a lower die base 10 is installed. At one ends of the left and right sides of the bottom end of the lower die base 10, one ends of limit rods 11 are installed, and the other ends of the limit rods 11 sequentially penetrate through the springs 9 and the outer wall of the workbench 1. On the inner circumference of the inner cavity of the lower die base 10, guide rods 12 are provided. A base 13 is sleeved on the outer wall of the guide rods 12. On the outer circumference of the outer wall of the lower die base 10, electric push rods 14 are connected by screws. The inner output ends of the electric push rods 14 extend into the inner cavity of the lower die base 10 and are fixedly connected to the outer wall of the base 13. At one end of the outer side top end of the base 13, one end of a push rod 15 is installed. The other end of the push rod 15 extends out of the outer wall of the lower die base 10 and a tactile sensor 16 is installed. Inside the tactile sensor 16, a top block 17 is provided.
[0019] As a preferred solution, furthermore, the upper die base 7 and the convex block 8 are matched with each other and their positions correspond.
[0020] As a preferred solution, furthermore, the limit rod 11 is arranged in a "convex" shape.
[0021] As a preferred solution, furthermore, the number of the guide rods 12 is three, and the three guide rods 12 are distributed on the inner wall circumference of the lower die base 10 at intervals of 120 degrees in the clockwise direction.
[0022] As a preferred solution, furthermore, the electric push rod 14 and the tactile sensor 16 are electrically connected to each other.
[0023] The electrical components mentioned in this solution are all prior arts. Only one of their models is listed here. As long as the electrical components can meet the requirements in this solution, they can be used.
[0024] Through the personnel in this field, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, the electrical connection should be completed according to the sequence of the working order of each electrical component in the following working principle. The detailed connection means are well-known techniques in this field. The following mainly introduces the working principle and process, and no further description of the electrical control will be made. The specific work is as follows.
[0025] In use, the raw material is placed on the lower mold base 10, and multiple electric push rods 14 are activated simultaneously. The electric push rods 14 cause the base 13 to move the push rod 15, tactile sensor 16, and push block 17 inwards or outwards. When multiple push blocks 17 move inwards simultaneously and abut against the outer wall of the raw material, the raw material is pushed to the center of the lower mold base 10. At this time, the three tactile sensors 16 detect that all three push blocks 17 are in contact with the raw material. The electric push rods 14 then pull the base 13, causing the push rod 15 to move the tactile sensor 16 and push block 17 outwards, thus removing the push block 17 from the lower mold base 10, completing the positioning of the raw material. The hydraulic cylinder 5 is then activated, causing the base 4, bracket 6, and upper mold base 7 to move downwards together. During this process, the upper mold base... The upper mold 7 will press against the outer wall of the raw material and push the lower mold base 10 downward. The lower mold base 10 will compress the spring 9, and the edge of the raw material on the lower mold base 10 will be pressed and move downward along with it. The middle part of the raw material will be pushed up by the protrusion 8, so that the raw material can be subjected to conventional stretching processing. After processing is completed, the hydraulic cylinder 5 will move the upper mold base 7 upward. The elasticity of the spring 9 will push the lower mold base 10 to reset. At this time, the processed raw material can be replaced. This device has an auxiliary positioning function, which can accurately position the raw material in the center of the workstation, effectively avoiding the need to rely on more raw material to make up for the local material shortage caused by deviation. It saves production costs, conforms to the development concept of green manufacturing and efficient use of resources, is easy to use, has strong practicality, and is suitable for promotion.
