Description

Technical Field

[0001] This utility model relates to the field of automotive leaf spring technology, and in particular to a support frame for heat treatment in automotive leaf spring production. Background Technology

[0002] Automotive leaf springs are the most traditional elastic elements in automotive suspension systems. They are widely used due to their high reliability, simple structure, short manufacturing process, low cost, and ability to significantly simplify the structure. An automotive leaf spring is generally composed of several alloy spring steel leaves of unequal length, forming a spring beam with approximately equal strength. In the suspension system, besides its cushioning function, when it is longitudinally mounted on the vehicle and hinged at one end to the frame, it can transmit forces and moments in all directions and determine the trajectory of the wheels, acting as a guide. Therefore, there is no need for other guiding mechanisms. Furthermore, since automotive leaf springs are composed of multiple stacked leaves, when deformed under load, the leaves slide relative to each other, generating friction and producing a certain resistance, thus reducing vehicle vibration. Therefore, this structure eliminates the need for shock absorbers. To address the issue of relaxation fatigue fracture under long-term alternating stress, automotive leaf springs are generally heat-treated. However, existing support frames for heat treatment in leaf spring production still have problems such as being unable to stably support the leaf springs, being unable to move them quickly, and being unable to quickly transport them into the heating furnace.

[0003] Therefore, it is essential to invent a support frame for heat treatment in the production of automotive leaf springs. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a support frame for heat treatment in automotive leaf spring production. This solves the issues of existing support frames failing to stably support the automotive leaf springs, hindering rapid movement, and preventing quick transport to the heating furnace. The support frame for heat treatment in automotive leaf spring production includes a movable bracket, a sliding bracket, a support bracket, a feeding bracket, a push-pull handle, and an automotive leaf spring. Two sets of sliding brackets are used, with the support brackets fixedly installed at both ends of the two sets of sliding brackets. The sliding brackets are slidably installed inside the movable bracket. The feeding brackets are fixedly installed on the inner sides of both ends of the support bracket, and the push-pull handles are fixedly installed on the outer sides of both ends of the support bracket. The automotive leaf spring is placed on the feeding bracket.

[0005] The mobile support includes a vehicle frame, a support carriage, a support skeleton, a sliding groove, and mobile wheels. The support carriage is fixedly installed on the top of the vehicle frame, and the support skeleton is fixedly installed between the support carriages. The sliding groove is opened inside the support carriage, and the mobile support is slidably installed inside the sliding groove. The mobile wheels are fixedly installed on the bottom of the vehicle frame.

[0006] The support bracket includes an adjusting cylinder, a support arm, fixing bolts, and a mounting block. The support arm is slidably installed inside both ends of the adjusting cylinder and is fixed by applying inward pressure with the fixing bolts. The mounting block is fixedly installed on the outer end of the support arm.

[0007] The movable support is a vehicle-shaped stainless steel metal support, and the entire movable support can be moved by movable wheels; there are 4 supporting slides, which are installed on the upper part of the vehicle frame in a two-upper-two-lower configuration; all sliding grooves face inward, and the position of the sliding grooves is completely consistent with the position of the movable support, and the height of the sliding grooves is consistent with the height of the sliding grooves inside the heating furnace; the sliding grooves allow the movable support to slide directly into the sliding groove inside the heating furnace.

[0008] The support bracket is divided into upper and lower layers, which can hold two layers of automotive leaf springs; the support arm can slide the middle cylinder, and the extension and retraction of the support arm can drive the feeding bracket to move closer or further away. The support arm can control the movement of the feeding bracket so that the hooks at both ends of the automotive leaf spring are suspended above it.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The movable support frame of this utility model allows for flexible movement of the entire machine via the bottom casters and push-pull handles, facilitating the transfer of the leaf springs to their respective workstations. Its precisely designed sliding groove seamlessly connects with the heat treatment furnace track, allowing the sliding frame to slide directly into the furnace, avoiding secondary handling under high-temperature conditions. Furthermore, its stainless steel material ensures high-temperature resistance and deformation resistance in the heat treatment environment, a key foundation for the efficient and stable operation of the entire system.

[0011] 2. The support bracket of this utility model, through the design of the material feeding brackets at both ends and the telescopic support arm, can not only stably suspend automotive leaf springs of different specifications, but also adapt to the processing needs of various lengths; by adjusting the matching structure of the middle cylinder and the fixing bolt, the support span can be flexibly adjusted and quickly locked; by using the mounting block to organically combine the entire support system with the mobile bracket, while ensuring structural stability, the push-pull handle on the outside optimizes the human-machine operation experience, making it a key functional module integrating load-bearing, adjustment and connection functions.
