AI Technical Summary
Chain clamps wear and deform during long-term use, causing the cotter pins to become unable to hold, increasing the probability of failure. Current technology requires replacing the entire clamp handle, which is costly and difficult to repair.
Design a chain clamp punching tool that allows for the reuse of the clamp handle by re-punching holes at the same position on the other side of the clamp handle, utilizing the existing Y-shaped structure of the clamp handle fixing arm and the shared connecting part.
It reduces maintenance costs and difficulty, increases the reusability of chain clamps, and ensures normal equipment operation.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to sheet production technical field, especially relate to a chain clamp punching frock. BACKGROUND
[0002] The function of the chain clamp is to clamp the sheet and make it be stretched horizontally in TDO (transverse direction stretching). In order to make the stretching process of the sheet smooth, multiple chain clamps are needed to clamp the sheet at the same time. Since the TDO is in a long-term running state and the number of chain clamps is large, the chain clamp fittings are inevitably worn out during the long opening and closing process, and even the clamps themselves can be worn and deformed. After the pin hole of the clamp handle is worn out, the new cotter pin cannot be firmly fixed, the frequency of loosening is greatly increased, and the probability of failure during operation is also greatly improved. SUMMARY
[0003] The utility model embodiment aims at providing a chain clamp punching frock, which can make a punching frock, re-punch at the same position on the other side of the clamp handle, and improve the reusability of the clamp handle.
[0004] The utility model embodiment is implemented in the following manner:
[0005] A chain clamp punching frock comprises a frock base, a clamp handle fixing arm, a main clamp handle fixing pin hole and a standby clamp handle fixing pin hole. The clamp handle fixing arm is arranged on the frock base. The clamp handle fixing arm has two and is arranged in parallel. The main clamp handle fixing pin hole is located on one clamp handle fixing arm. The standby clamp handle fixing pin hole is located on the other clamp handle fixing arm.
[0006] The two clamp handle fixing arms have a common connecting part integrally connected. The common connecting part is fixed on the frock base.
[0007] The clamp handle fixing arm has a Y-shaped structure.
[0008] The utility model embodiment can improve the reusability of the clamp handle by making a punching frock and re-punching at the same position on the other side of the clamp handle. The chain clamp can be normally used at the lowest cost without the need to order other non-interchangeable fittings or replace the clamp handle by ordering a new one. The maintenance time is short and the maintenance difficulty is low. BRIEF DESCRIPTION OF DRAWINGS
[0009] Figure 1 It is a structure diagram of the chain clamp punching frock of the utility model. DETAILED DESCRIPTION
[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0011] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:
[0012] like Figure 1 As shown, a chain clamp punching fixture includes: a fixture base 1, a clamping handle fixing arm 2, a main clamping handle fixing pin hole 3, and a spare clamping handle fixing pin hole 4. The clamping handle fixing arm is disposed on the fixture base. There are two clamping handle fixing arms, which are arranged in parallel. The main clamping handle fixing pin hole is located on one clamping handle fixing arm, and the spare clamping handle fixing pin hole is located on the other clamping handle fixing arm.
[0013] In the figure, the two clamping arms have a common connecting part that is integrally connected and fixed on the tooling base. The clamping arms have a Y-shaped structure.
[0014] In this embodiment of the invention, to ensure that the sheet material can be stretched to the ideal width within the TDO, the length of the TDO itself cannot be less than a certain number of meters. Therefore, a sufficient number of chain clamps are required to fix the sheet material within the track. Considering the operation of the TDO, the chain clamps experience frequent wear and replacement. Consequently, wear of the pin holes in the chain clamp handles is also frequent. When the pin holes are severely worn, cotter pins cannot be installed, and the chain clamp handle cannot be fixed. A drilling fixture can re-drill pin holes at the same location on the other side of the handle. This allows the chain clamp to be reused simply by reversing the direction of the connecting shaft. This allows the chain clamp to function normally at the lowest cost, eliminating the need to order other non-interchangeable parts or order new handles for replacement. Maintenance time is short, and maintenance difficulty is low.
[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
