Description

Technical Field

[0001] The invention relates to the technical field of spring production, in particular to a sealing oblique spring production tool. Background Art

[0002] Sealed oblique springs are generally used at the interfaces of electrical equipment to play the role of sealing electromagnetic shielding. Existing seals are all produced automatically using torsion spring machines. They are rolled and bent at the same time, and then cut to a certain length and laser welded at the ends to complete the production of the oblique spring. However, torsion spring machines only use springs with larger wire diameters and inclination angles. For springs with small wire diameters and small inclination angles, the small wire diameter can easily lead to deformation and extrusion during the feeding process of the torsion spring machine, making production difficult and requiring frequent shutdowns for cleaning. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a sealing oblique spring production tooling, which changes the production method of small-diameter sealing oblique springs through the cooperation between the deformation module and the tempering module, and solves the problem of difficulty in automatic production by torsion spring machines.

[0004] In order to solve the above technical problems, the present invention provides a technical solution: a sealing oblique spring production tool, including a deformation module and a tempering module, characterized in that: the deformation module includes a bottom plate, a support rod and a pressing block, the bottom plate is provided with a pressing groove and a placement groove, the curvature of the pressing groove matches the curvature of the sealing oblique spring, and the depth of the pressing groove is half of the outer diameter of the sealing oblique spring, and the diameter of the support rod is half of the inner diameter of the sealing oblique spring; The tempering module comprises a fixing plate and a fixing ring. The fixing plate is a circular structure. The fixing ring is sleeved on the fixing plate, and a gap between the fixing plate and the fixing ring is matched with a gap of the annular sealing oblique spring.

[0005] Furthermore, two ends of the pressing groove and the placing groove are connected to two ends of the bottom plate.

[0006] Furthermore, the pressing block is provided with a handle.

[0007] Furthermore, the bottom plate has limiting grooves for the support rod, the pressing block, the fixing plate and the fixing ring to be respectively embedded in.

[0008] In order to solve the above technical problems, another technical solution provided by the present invention is: based on the production method of the sealing oblique spring production tooling described above, Step 1: Use a spring coiling machine to coil the wire, and cut the coiled wire into a certain length to form a round spring; Step 2: Hold the coil spring and the support rod, insert one end of the support rod into the coil spring, and place the coil spring in the pressing groove; Step 3: Press the support rod exposed from the end of the coil spring, press the coil spring into the pressing groove, take the pressing block and place it on one end of the coil spring; Step 4: Press the pressing block downward to bend and tilt the circular spring, then continue to press the pressing block and move it to the other end of the circular spring so that the entire circular spring is in a bent and tilted state; Step 5: Pick up the round spring in the bent and tilted state, pull out the support rod and perform laser welding at the ends to make the whole into a closed circular ring; Step 6: Put the closed circular spring on the fixed plate, and then put the fixed ring on the circular spring to limit and fix the circular spring. Then temper them together and cool them to room temperature to complete the production of the inclined spring.

[0009] Furthermore, the coiling and cutting of the wire are both completed by a spring coiling machine.

[0010] Furthermore, when the pressing block is tilted downward to press and bend the circular spring, the bending and inclination direction of the circular spring is the same as the moving direction of the pressing block.

[0011] Furthermore, when taking the support rod from the placement slot or taking the support rod and the round spring from the pressing slot, the support rod and the oblique spring are moved out of the placement slot or the pressing slot by pushing them.

[0012] The beneficial effects of the present invention are: 1. The present application changes the production of oblique springs through the cooperation between the deformation module and the tempering module. Only the spring coiling machine is used for coiling the springs, and the bending step is replaced by manual work through the deformation module. After welding, the tempering operation is performed through the tempering module. After the bending state is finalized, the production of the oblique spring is completed, thereby solving the problem that the production process of the existing torsion spring machine is difficult and requires frequent shutdowns for cleaning.

[0013] 2. In this application, the sizes and wire diameters of the pressing groove, support rod and inclined spring match each other to ensure the bending quality and improve the success rate of manual bending. The semi-finished products after welding are tempered by the fixing plate and fixing ring to shape the bend, reduce the chance of rebound during manual bending, and ensure product quality.

[0014] 3. In the present application, the two ends of the pressing groove and the placement groove are connected to the two ends of the bottom plate, so as to facilitate pushing the support rod and the oblique spring out of the pressing groove and the placement groove and taking the support rod and the oblique spring.

[0015] 4. In the present application, a handle is provided on the pressing block, which is convenient for taking the handle to bend the spring placed in the pressing groove. At the same time, the bottom plate is provided with limiting grooves for the support rod, pressing block, fixing plate and fixing ring to be respectively embedded, so that the support rod, pressing block, fixing plate and fixing ring can be stored and placed to form a whole, which is convenient for storage and transportation.
